TECHNICAL FIELD
[0001] The present invention relates to an inhaler, a control device for an inhaler, an
information processing method, and a program.
BACKGROUND ART
[0002] Inhalers, such as an electronic cigarette, a nebulizer, and so on, each of which
generates gas to which a flavor component that is to be sucked by a user has been
added, have spread through the market. For example, a flavor component generating
base-material which contributes to generation of gas to which flavor components have
been added, such as a flavor source for adding flavor to an aerosol source for generating
aerosol or to aerosol, is installed in an inhaler; and contents stored in the flavor
component generating base-material are consumed every time when the flavor-component-added
gas is generated. A user can taste the flavor together with the gas, by sucking (hereinafter,
this action may be referred to as puffing) the flavor-component-added gas generated
by each of the above inhalers.
[0003] For making it possible to generate flavor-component-added gas in a satisfactory manner,
it is desirable that a flavor component generating base-material be installed correctly
in an inhaler. In view of the above point, for example, Patent Literature 1 discloses
a technique for detecting, by using an optical sensor, a state with respect to whether
a cigarette has been inserted in a device which heats a cigarette inserted therein
to make a flavor component be allowed to be sucked.

DESCRIPTION OF EMBODIMENTS
[0033] In the following description, preferred embodiments of the present invention will
be explained in detail with reference to the attached figures. In this regard, in
the specification and the figures, for omitting overlapping explanations, a reference
number that is the same as that assigned to one component is assigned to the other
component, in the case that the other component has a function/construction that is
substantially the same as that of the one component.
<< 1. Basic Construction >>
[0034] In the following description, a basic construction example of an inhaler according
to the present invention will be explained with reference to Figs. 1-3. Fig. 1 is
a figure showing a construction example of an inhaler 100 according to an embodiment
of the present invention.
[0035] Fig. 1 is a general perspective view of an inhaler according to an embodiment of
the present invention. Fig. 2 is a general perspective view of the inhaler in the
state that it is holding a flavor component generating base-material, according to
the embodiment of the present invention. In the present embodiment, the inhaler 100
is constructed to generate aerosol including a flavor, for example, by heating a flavor
component generating base-material, such as a smoking article, which comprises an
aerosol source and a filling article including a flavor source. In the present embodiment,
a smoking article 200 is used as a flavor component generating base-material.
[0036] A person skilled in the art will understand that the smoking article 200 is a mere
example of a flavor component generating base-material. An aerosol source included
in a flavor component generating base-material may be solid or liquid. The aerosol
source may be liquid such as polyhydric alcohol, such as glycerin or propylene glycol,
or water, or the like, for example. The aerosol source may comprise a tobacco raw
material or an extract originated from a tobacco raw material, which releases a fragrance-inhaling-taste
component when it is heated. In the case that the inhaler 100 is an inhaler for medical
use, such as a nebulizer or the like, the aerosol source may comprise a medicine that
is to be sucked by a patient. The flavor component generating base-material may not
comprise a flavor source, depending on intended use thereof. Further, gas, to which
flavor components generated from a flavor component generating base-material are to
be added, is not limited to aerosol, and, for example, invisible vapor may be generated.
[0037] As shown in Figs. 1 and 2, the inhaler 100 comprises a top housing 171A, a bottom
housing 171B, a cover 172, a power source switch 173, and a lid part 174. Further,
as shown in Fig. 2, the inhaler 100 comprises a holding part 175 and a heating unit
176 therein. The outermost housing 171 of the inhaler 100 is constructed as a result
that the top housing 171A and the bottom housing 171B are connected to each other.
The housing 171 may have a size that fits in a hand of a user. In the above case,
when a user uses the inhaler 100, the user can hold the inhaler 100 by a user's hand,
and suck aerosol.
[0038] The top housing 171A comprises an opening (not shown in the figures), and the cover
172 is coupled to the top housing 171A to close the opening. As shown in Fig. 2, the
cover 172 has an opening 172a into which the smoking article 200 can be inserted.
The lid part 174 is constructed to open/close the opening 172a of the cover 172. Specifically,
the lid part 174 is attached to the cover 172, and constructed to be able to move,
along a surface of the cover 172, between a first position for closing the opening
172a and a second position for opening the opening 172a.
[0039] The power source switch 173 is used for switching between an ON state and an OFF
state of operation of the inhaler 100. For example, in a state that the smoking article
200 has been inserted in the opening 172a and attached therein as shown in Fig. 2,
a user can make the smoking article 200 be heated without combustion thereof, by manipulating
the power source switch 173 to thereby supply electric power from a battery (not shown
in the figures) to the heating unit 176. As a result that the smoking article 200
is heated, aerosol is generated from an aerosol source included in the smoking article
200, and flavor in a flavor source is taken in the aerosol. A user can suck aerosol
including flavor, by sucking it from a part of the smoking article 200 projecting
from the inhaler 100 (the part shown in Fig. 2).
[0040] In this regard, in this specification, a direction along that a flavor component
generating base-material such as the smoking article 200 is inserted to the opening
172a is also referred to as an inserting direction, and a direction along that a flavor
component generating base-material such as the smoking article 200 is pulled out from
the opening 172a is also referred to as a pulling-out direction. In the case that
it is not necessary to specifically distinguish between the inserting direction and
the pulling-out direction, these directions are also collectively referred to as a
longitudinal direction.
[0041] The holding part 175 comprises an inner space, and houses part of the smoking article
200 in the inner space and holds the smoking article 200. The holding part 175 comprises
the opening 172a which makes the inner space communicate with an outer space, and
holds the smoking article 200 inserted from the opening 172a to the inner space. For
example, the holding part 175 is a cylindrical body extending along the longitudinal
direction, and defines a columnar inner space. The holding part 172 may be constructed
in such a manner that, at least in part thereof in the longitudinal direction, an
inner diameter is smaller than an outer diameter of the smoking article, and may hold
the smoking article 200 inserted in the inner space by pressing the smoking article
200 from the outer periphery thereof. The holding part 175 also has a function to
define a flow path of air supplied to the smoking article.
[0042] In the state that the smoking article 200 is being held by the holding part 175,
if a user holds the part protruding from the opening 172a of the smoking article 200
in the user's mouth and performs a sucking action, air flows into the inside of the
holding part 175 from a hole which is not shown in the figures. The air that has flown
into the inside of the holding part 175 passes through the inside, and, together with
aerosol generated from the smoking article 200, arrives at the inside of the mouth
of the user. Thus, the side closer to the opening 172a of the holding part 175 is
a downstream side, and the side opposite thereto is an upstream side. In the example
shown in Fig. 2, the pulling out direction is that to the downstream side, and the
inserting direction is that to the upstream side.
[0043] The heating unit 176 has a function to heat the smoking article 200 held in the inner
space of the holding part 175 from the outer periphery of the smoking article 200,
by heating the inner space of the holding part 175 from the outer periphery thereof.
At least part of the holding part 175 may be the heating unit 176. For example, the
heating unit 176 may be a cylindrical body extending along the longitudinal direction,
and may be part of the construction of the holding part 175. Also, the heating unit
176 may be arranged on the circumference of the holding part 175, and may heat the
smoking article 200 across the holding part 175. In this regard, the heating unit
176 is a mere example of a function part which applies, to a flavor component generating
base-material held in the holding part, a function that makes the flavor component
generating base-material generate flavor-component-added gas. Regarding the function
applied to the flavor component generating base-material, the function is not limited
to a heating function, and may be any function such as an ultrasonic vibration function
or the like.
[0044] The construction of the inhaler 100 shown in each of Figs. 1 and 2 is a mere example
of the inhaler according to the present invention. The inhaler according to the present
invention can be constructed to have any one of various types of forms, wherein, in
each form, flavor-component-added gas is generated from a flavor component generating
base-material by holding the flavor component generating base-material and applying
a function, and the generated gas is allowed to be sucked by a user.
[0045] Next, as an example of a flavor component generating base-material used in the inhaler
100 according to the present embodiment, the construction of the smoking article 200
will be explained. Fig. 3 is a cross-section view of the smoking article 200. In the
embodiment shown in Fig. 3, the smoking article 200 comprises a base-material part
200A, which comprises a filling article 201 and first rolling paper 202 by which the
filling article 201 is wound, and a suction opening part 200B which forms an end part
opposite to the base-material part 200A. The base-material part 200A and the suction
opening part 200B are connected by second rolling paper 203 which is different from
the first rolling paper 202. In this regard, it is possible to connect the base-material
part 200A and the suction opening part 200B by using the first rolling paper 202,
i.e., by omitting the second rolling paper 203.
[0046] The suction opening part 200B in Fig. 3 comprises a paper tube part 204, a filter
part 205, and a hollow segment part 206 positioned between the paper tube part 204
and the filter part 205. For example, the hollow segment part 206 comprises a filling
layer including one or plural hollow channels, and a plug wrapper for covering the
filling layer. Since the density of filled fibers in the filling layer is high, air
and aerosol flows through the hollow channel only, and almost no air and aerosol flows
through the filling layer, when suction action is performed. Regarding the smoking
article 200, if it is desired to lower a decrease in the quantity of delivery of aerosol
due to filtering of the aerosol components in the filter part 205, shortening the
length of the filter part 205 and replacing that part by the hollow segment part 206
will be effective for increasing the quantity of delivery of the aerosol.
[0047] In the embodiment shown in Fig. 3, the suction opening part 200B comprises three
segments. However, in the other embodiment, the suction opening part 200B may be constructed
by using one or two segments, or may be constructed by using four or more segments.
For example, it is possible to omit the hollow segment part 206, and form the suction
opening part 200B by arranging the paper tube part 204 and the filter part 205 adjacent
to each other.
[0048] In the embodiment shown in Fig. 3, regarding the length in the longitudinal direction
of the smoking article 200, it is preferable to set it to 40-90 mm, more preferable
to set it to 50-75 mm, and still more preferably to set it to 50-60 mm. Regarding
the circumference of the smoking article 200, it is preferable to set it to 15-25
mm, more preferable to set it to that equal to or less than 17-24 mm, and still more
preferably to set it to 20-22 mm. Further, regarding the smoking article 200, the
length of the base-material part 200A may be 20 mm, the length of the first rolling
paper 202 may be 20 mm, the length of the hollow segment part 206 may be 8 mm, and
the length of the filter part 205 may be 7 mm. The length of each of the above segments
may be changed appropriately, according to suitability to manufacture, required quality,
and so on.
[0049] In the present embodiment, the filling article 201 in the smoking article 200 may
comprise an aerosol source which generates aerosol when it is heated at predetermined
temperature. The kind of the aerosol source is not specifically limited, and extracted
material and/or components obtained from various natural products may be selected
as an aerosol source according to intended use. Glycerin, propylene glycol, triacetin,
1,3-butanediol, and a mixture thereof, for example, can be listed as aerosol sources.
The aerosol source content of the filling article 201 is not specifically limited;
and, in view of generation of sufficient quantity of aerosol and satisfactory addition
of fragrance inhaling taste, the aerosol source content is usually equal to or greater
than 5 weight percent, and is preferably equal to or greater than 10 weight percent,
and is usually equal to or less than 50 weight percent, and is preferably equal to
or less than 20 weight percent.
[0050] The filling article 201 in the smoking article 200 in the present embodiment may
comprise shredded tobacco as a flavor source. The material of shredded tobacco is
not specifically limited, and publicly known material such as a lamina, a stem, and
so on may be used as the material. The range of the content of the filling article
201 in the smoking article 200, in the case that the circumference is 22 mm and the
length is 20 mm, is, for example, 200-400 mg, and is preferably 250-320 mg. The water
content of the filling article 201 is, for example, 8-18 weight percent, and is preferably
10-16 weight percent. In the case that the water content is that explained above,
occurrence of staining at the time of rolling is suppressed, and suitability to rolling
at the time of manufacture of the base-material part 200A is made satisfactory. There
is no special limitation with respect to the size, the preparation method, and so
on of the shredded tobacco used as the filling article 201. For example, dried tobacco
leaves cut into pieces, each having the width of 0.8-1.2 mm, may be used. Alternatively,
dried tobacco leaves are crushed and uniformized to become particles, regarding which
the average particle size is approximately 20-200 µm, and the particles are processed
to become a sheet, and the sheet cut into pieces, each having the width of 0.8-1.2
mm, may be used. Further, the above sheet formed via the sheet process may be processed
to gather it without cutting it, and the gathered sheet may be used as the filling
article 201. Further, the filling article 201 may comprise one kind or two or more
kinds of flavors. The kinds of flavors are not specifically limited; however, in view
of provision of satisfactory smoke flavor, a flavor is menthol, preferably.
[0051] In the present embodiment, each sheet of the first and second rolling paper 202 and
203 in the smoking article 200 may be constructed by use of base paper which has the
basis weight of, for example, 20-65 gsm, preferably, 25-45 gsm. The thickness of each
sheet of the first and second rolling paper 202 and 203 is not specifically limited;
however, in view of rigidness, gas permeability, and easiness of adjustment at the
time of paper manufacture, the thickness is set to 10-100 µm, preferably, set to 20-75
µm, and, more preferably, set to 30-50 µm.
[0052] In the present embodiment, filler may be included in the rolling paper 202 and 203
in the smoking article 200. The filler content may be equal to or greater than 10
weight percent and less than 60 weight percent, and, may preferably be 15-45 weigh
percent, with respect to the total weight of the first rolling paper 202 and the second
rolling paper 203. In the present embodiment, it is preferable that the filler be
15-45 weight percent, with respect to a preferable range of basis weight (25-45 gsm).
For example, calcium carbonate, titanium dioxide, kaolin, and so on may be used as
filler. Paper including filler such as that explained above presents a white color
that is preferable in view of appearance of paper used as rolling paper of the smoking
article 200, and is able to keep its whiteness permanently. By including a large quantity
of filler such as that explained above, the ISO whiteness of rolling paper can be
raised to 83 % or more, for example. Further, in view of practicality in terms of
use of it as rolling paper in the smoking article 200, it is preferable that the first
rolling paper 202 and the second rolling paper 203 have the tensile strength of 8N/15mm
or more. The tensile strength can be increased by reducing the filler content. Specifically,
the tensile strength can be increased by reducing the filler content to that less
than the upper limit of the filler content that has been shown with respect to each
range of the basis weight illustrated in the above description.
<< 2. First Embodiment >>
[0053] The present embodiment has a form wherein a pressure sensor is installed in a downstream-side
end part of a holding part, and the state of arrangement of a flavor component generating
base-material in the holding part is specified based on result of detection by the
pressure sensor.
(Construction Example)
[0054] Fig. 4 is a block diagram showing an example of a schematic construction of an inhaler
100 in the state that it is holding a smoking article 200, according to a first embodiment.
As shown in Fig. 4, the inhaler 100 comprises a pressure sensor 177, a battery 178,
a notification unit 179, and a control unit 180, in addition to the components explained
with reference to Figs. 1 and 2. In this regard, representation of the same components
(for example, the heating unit 176 and the pressure sensor 177) in the figure, that
are represented in such a manner that they hold the holding part 175 between them
from the top side and the bottom side of the holding part 175, represents the construction
that components are installed in such a manner that they surround the holding part
175. In the following description, the above matter also apply to other block diagrams.
[0055] The pressure sensor 177 detects pressure applied to an inner wall of the holding
part 175. The inner wall of the holding part 175 is a wall defining the inner space
of the holding part 175. For example, the pressure sensor 177 may detect pressure
applied to at least one point in the inner wall, may detect a total value of pressure
applied to a predetermined area of the inner wall, or may detect distribution of pressure
applied to a predetermined area of the inner wall. The pressure sensor 177 is installed
in a position, in the inner wall of the holding part 175, that is closer to the side
of the opening 172a than the position heated by the heating unit 176, and detects
pressure applied to the inner wall in the position where the pressure sensor 177 is
installed. In the example shown in Fig. 4, the pressure sensor 177 is installed in
the downstream-side end part of the holding part 175, and detects pressure applied
to the inner wall of the downstream-side end part. For example, the holding part 175
is that holding the smoking article 200 in such a manner that it applies pressure
to the outer periphery of the smoking article 200, and the pressure sensor 177 is
installed in a part in the holding part 175 where the inner diameter thereof is smaller
than the outer diameter of the smoking article 200. Thus, pressure applied to the
above part is detected by the pressure sensor 177. The pressure sensor 177 is also
able to detect attachment/detachment of the smoking article 200 to/from the inhaler
100, based on judgment as to whether or not the detected pressure is equal to or greater
than a predetermined threshold value. Since the pressure sensor 177 is installed in
the downstream-side end part of the holding part 175, the pressure sensor 177 can
be separated from the heating unit 176 and failure of the pressure sensor 177 due
to the heat can be prevented.
[0056] The inhaler 100 may comprise any sensors different from the pressure sensor 177.
For example, the inhaler 100 may comprise a pressure sensor for detecting change in
air pressure in the inside of the holding part 175 or a flow rate sensor for detecting
a flow rate of aerosol, and presence/absence of suction action and the quantity of
suction by a user may be detected by the above sensors. The above pressure sensor
or flow rate sensor may be constructed to count the number of times of puffs performed
by a user by using the inhaler 100. Further, the inhaler 100 may comprise a weight
sensor for detecting the weight of the smoking article 200. Further, the inhaler 100
may comprise a sensor which accumulates time of electrical conduction to the heating
unit 176. Further, the inhaler 100 may comprise a sensor for detecting an SOC (State
of Charge), an integrated current value, a voltage, or the like of the battery 178.
The integrated current value may be obtained by using a current integration method,
an SOC-OCV (Open Circuit Voltage) method, or the like.
[0057] The battery 178 is a power source which stores electric power, and supplies electric
power to the respective components in the inhaler 100, such as the heating unit 176,
the notification unit 179, the pressure sensor 177, the control unit 180, and so on.
The battery 178 may be a rechargeable battery or a non-rechargeable battery, for example.
The battery 178 may be charged by connecting it to an external electric power source
via a predetermined port (not shown in the figure) of the inhaler 100. The battery
178 only may be able to be detached from the inhaler 100, and may be able to be replaced
by a new battery 178.
[0058] The notification unit 179 may comprise a light emitting element such as an LED (Light
Emitting Diode), a display, a speaker, a vibrator, and so on. The notification unit
179 is constructed to provide a user with some information by performing at least
one of light emission, display, sound output, and vibration actions, as necessary.
Further, the notification unit 179 may comprise a communication device, and transmit
information to the other device such as a smartphone or the like to provide a user
with the information via the other device.
[0059] The control unit 180 functions as an arithmetic processing unit and a control device,
and controls overall operation in the inhaler 100. The control unit 180 may be an
electronic circuit module constructed as a microprocessor or a microcomputer. The
control unit 180 may be constructed to control operation of the inhaler 100 in accordance
with computer-executable instructions stored in a storage unit which is not shown
in the figure. The storage unit is a storage medium such as a ROM (Read Only Memory),
a RAM (Random Access Memory), a flash memory, or the like. The storage unit may store,
in addition to computer-executable instructions such as those explained above, setting
data which are necessary for controlling the inhaler 100 and other data. For example,
the storage unit may store various data such as methods for controlling the notification
unit 179 (modes of light emission, vocalization, vibration, etc., and so on), values
detected by the pressure sensor 177, history of heating by the heating unit 176, and
so on. The control unit 180 reads data from the storage unit and uses the data for
controlling the inhaler 100 as necessary, and stores data in the storage unit as necessary.
[0060] The smoking article 200 is inserted into the holding part 175 and held thereby. In
the state that the smoking article 200 is being held in the holding part 175, the
longitudinal direction of the inhaler 100 and the longitudinal direction of the smoking
article 200 coincide or approximately coincide with each other. In the following description,
it is supposed that the longitudinal direction of the inhaler 100 and the longitudinal
direction of the smoking article 200 coincide with each other, unless specifically
explained. The smoking article 200 is inserted into the inner space of the holding
part 175 from the opening 172a in such a manner that the base-material part 200A which
is defined as the head is inserted first into the holding part 175, and is held in
the state that at least part of the suction opening part 200B protrudes to the outer
space. With respect to the ends of the smoking article 200 in the longitudinal direction,
one end positioned in the base-material part 200A side is referred to as a tip 210a,
and the other end positioned in the suction opening part 200B side is also referred
to as a rear end 210b.
[0061] In this regard, the base-material part 200A includes, as contents, an aerosol source
and a flavor source, to which flavor-component-added gas contributes. The base-material
part 200A corresponds to a flavor component generating part of a flavor component
generating base-material. On the other hand, the suction opening part 200B is a part,
that is to be held in a user's mouth, for allowing suction of aerosol generated by
the base-material part 200A, and does not include a flavor source or a aerosol source,
typically. The suction opening part 200B corresponds to a part, which is not the flavor-component
generating part, of a flavor component generating base-material.
(Operation)
- Specifying of Arrangement
[0062] The control unit 180 specifies, based on result of detection by the pressure sensor
177, arrangement of the smoking article 200 in the inner space of the holding part
175. Arrangement of the smoking article 200 in the holding part 175 refers to arrangement
of the smoking article 200 inserted into the inner space of the holding part 175 in
the longitudinal direction. If it is explained more simply, arrangement of the smoking
article 200 in the holding part 175 refers to a position of the tip 210a of the smoking
article 200 in the longitudinal direction, in other words, the depth that the smoking
article 200 is inserted.
[0063] For example, the control unit 180 judges whether arrangement of the smoking article
200 in the holding part 175 corresponds to predetermined correct arrangement. The
arrangement shown in Fig. 4 is an example of correct arrangement. Correct arrangement
is that wherein the base-material part 200A and a part of the suction opening part
200B are held in the inner space of the holding part 175, and the other part of the
suction opening part 200B protrudes from the opening 172a to the outer space. The
longitudinal-direction length L
S from a bottom part 175a of the holding part 175 to the opening 172a is longer than
the longitudinal-direction length L
T-A of the base-material part 200A, and shorter than the longitudinal-direction length
L
T of the smoking article 200. Thus, for example, if the smoking article 200 is inserted
in such a manner that the tip 210a of the smoking article 200 touches the bottom part
175a of the holding part 175 (i.e., reaches the innermost place), it is regarded that
the arrangement of the smoking article 200 corresponds to the correct arrangement.
In the other point of view, correct arrangement refers to arrangement wherein the
smoking article 200 is positioned in a position heated by the heating unit 176. In
the case that arrangement of the smoking article 200 corresponds to correct arrangement,
heat is applied by the heating unit 176 to part, that is larger when compared with
the part in the case that the arrangement of the smoking article 200 does not correspond
to the correct arrangement, of the base-material part 200A, uneven heating can be
prevented, and flavor-component-added aerosol can be generated efficiently. Further,
in the case that arrangement of the smoking article 200 corresponds to correct arrangement,
heating by the heating unit 176 without an object to be heated can be prevented.
[0064] Regarding the smoking article 200, the smoking article 200 comprises the base-material
part 200A and the suction opening part 200B which are positioned in an order in the
longitudinal direction from the position of the tip 210a to the position of the rear
end 210b, and hardness of one of them is different from that of the other. It is desirable
to set the range of hardness of the base-material part 200A and the range of hardness
of the suction opening part 200B in such a manner that they are separated from each
other by more than a predetermined value for ensuring accuracy with respect to specifying
of arrangement of the smoking article 200. Typically, the hardness of the base-material
part 200A is uniform and the hardness of the suction opening part 200B is uniform,
in the longitudinal direction; and the base-material part 200A is softer than the
other, i.e, the suction opening part 200B is harder than the other.
[0065] The control unit 180 uses a difference between the hardness of the base-material
part 200A and the hardness of the suction opening part 200B to specify arrangement
of the smoking article 200 in the holding part 175. Specifically, the control unit
180 judges that arrangement of the smoking article 200 corresponds to correct arrangement,
in the case that the pressure detected by the pressure sensor 177 is that within a
range of pressure comprising pressure that is assumed to be detected when arrangement
of the smoking article 200 corresponds to correct arrangement. In the present case,
the longitudinal-direction length L
C from the bottom part 175a of the holding part 175 to the position where the pressure
sensor 177 detects pressure is longer than the longitudinal-direction length L
T-A of the base-material part 200A and shorter than the longitudinal-direction length
L
T of the smoking article 200. Thus, in the case that arrangement of the smoking article
200 corresponds to correct arrangement, the suction opening part 200B positions in
the position where the pressure sensor 177 detects pressure, as shown in Fig. 4. Accordingly,
the control unit 180 judges that arrangement of the smoking article 200 corresponds
to correct arrangement, in the case that pressure corresponding to the hardness of
the suction opening part 200B is detected by the pressure sensor 177. For example,
the control unit 180 judges that arrangement of the smoking article 200 corresponds
to correct arrangement, in the case that pressure detected by the pressure sensor
177 is equal to or greater than a predetermined threshold value. On the other hand,
the control unit 180 judges that arrangement of the smoking article 200 does not correspond
to the correct arrangement, in the case that pressure detected by the pressure sensor
177 is less than the predetermined threshold value. For example, the predetermined
threshold value is any value between a pressure value corresponding to the hardness
of the base-material part 200A and a pressure value corresponding to the hardness
of the suction opening part 200B.
[0066] Regarding operation modes of the inhaler 100, the modes may include a sleep mode,
a standby mode, and heating mode. The sleep mode is an operation mode for monitoring
pressing of the power source switch 173. The standby mode is an operation mode for
monitoring arrangement of the smoking article 200 in the holding part 175 and monitoring
judgement with respect to whether a condition to perform heating is satisfied. The
heating mode is an operation mode for performing supplying of electric power to the
heating unit 176. If the power source switch 173 is pressed when the operation mode
of the inhaler 100 is the sleep mode, the mode changes to the standby mode. After
the mode is changed to the standby mode, supplying of electric power from the battery
178 to the pressure sensor 177 is started, so that the pressure sensor 177 is brought
to a state wherein it can detects pressure, and the above-explained process to specify
arrangement of the smoking article 200 is performed. It may also be possible to continue
specifying of arrangement of the smoking article 200 in the heating mode.
- Control Corresponding to Specified Arrangement
[0067] The control unit 180 controls, based on specified arrangement of the smoking article
200, the state with respect to supplying of electric power to the heating unit 176.
In more detail, in the case that it is specified that arrangement of the smoking article
200 corresponds to correct arrangement, the control unit 180 changes the state with
respect to supplying of electric power to the heating unit 176 to a state that allows
supplying of electric power to the heating unit 176. The state that allows supplying
of electric power to the heating unit 176 is a state wherein supplying of electric
power to the heating unit 176 is performed if a predetermined condition (hereinafter,
a heating performing condition) is satisfied in the state. On the other hand, in the
case that it is specified that arrangement of the smoking article 200 does not correspond
to correct arrangement, the control unit 180 changes the state with respect to supplying
of electric power to the heating unit 176 to a state that does not allow supplying
of electric power to the heating unit 176. The state that does not allow supplying
of electric power to the heating unit 176 is a state wherein supplying of electric
power to the heating unit 176 is not performed regardless of whether the heating performing
condition is satisfied. Supplying of electric power to the heating unit 176 is allowed
only when arrangement of the smoking article 200 corresponds to correct arrangement,
so that it becomes possible to prevent occurrence of uneven heating and heating without
an object to be heated.
[0068] The heating performing condition may be occurrence of an event that the power source
switch 173 is pressed. In the above case, the control unit 180 starts supplying of
electric power to the heating unit 176, in the case that the power source switch 173
is pressed during the state that allows supplying of electric power to the heating
unit 176. In more detail, the control unit 180 makes the battery 178 start supplying
of electric power to the heating unit 176 to make the heating unit 176 perform heating.
In the above case, a user can enjoy a good inhalation experience, during that uneven
heating or heating without an object to be heated does not occur, by simply pressing
the power source switch 173 and without specifically checking whether arrangement
of the smoking article 200 corresponds to correct arrangement. In this regard, in
the case that the operation mode of the inhaler 100 is the sleep mode, supplying of
electric power to the heating unit 176 is started by pressing the power source switch
173 two times. First pressing action applied to the power source switch 173 is the
action for making the inhaler 100 return to the standby mode from the sleep mode.
Second pressing action applied to the power source switch 173 is the action for starting
supplying of electric power to the heating unit 176. It should be reminded that the
power source switch 173 is an example of an operation input part which accepts an
input relating to operation from a user, and pressing of the power source switch 173
is an example of predetermined operation inputted to the operation input part. Alternatively,
the operation input part may be constructed by using any input device, such as a lever,
a touch sensor, or the like, for example; and the predetermined operation may be up
and down movement of a lever or touching on a touch sensor.
[0069] In a different example, the heating performing condition may be occurrence of an
event that an aerosol sucking action is performed by a user. In the above case, the
control unit 180 starts supplying of electric power to the heating unit 176, in the
case that an aerosol sucking action performed by a user is detected during the state
that allows supplying of electric power to the heating unit 176. In the above case,
a user can also enjoy a good inhalation experience, during that uneven heating or
heating without an object to be heated does not occur, by simply performing sucking
action and without specifically checking whether arrangement of the smoking article
200 corresponds to correct arrangement.
[0070] In a different example, the heating performing condition may be occurrence of an
event that a smoking article 200 is attached in such a manner that arrangement thereof
is correct. In the above case, the control unit 180 starts supplying of electric power
to the heating unit 176, in the case that it is specified based on result of detection
of pressure by the pressure sensor 177 that arrangement of the smoking article 200
corresponds to correct arrangement. Since heating is started right after the smoking
article 200 is attached in such a manner that arrangement thereof is correct, it becomes
possible to quickly allow a user to suck aerosol.
[0071] The control unit 180, when it has specified based on result of detection of pressure
by the pressure sensor 177 that arrangement of the smoking article 200 does not correspond
to correct arrangement, stops supplying of electric power to the heating unit 176,
immediately or after the elapse of a predetermined period of time, to stop hearting.
As a result, it becomes possible to prevent occurrence of uneven heating and heating
without an object to be heated, when the smoking article 200 is pulled out from the
holding part 175 or the position of the smoking article 200 is shifted by a user by
mistake.
[0072] Regarding an example of control other than control of the heating unit 176, the control
unit 180 may control the notification unit 179 to make it provide notification corresponding
to specified arrangement of the smoking article 200. For example, the control unit
180 makes the notification unit 179 output emission light, a display, sound, or vibration
corresponding to arrangement of the smoking article 200. In this regard, the control
unit 180 may control the notification unit 179 to make it output different notification,
according to judgment as to whether specified arrangement of the smoking article 200
corresponds to correct arrangement. For example, the notification unit 179 emits light
having a different emission pattern or a different color, and/or outputs different
sound, according to judgment as to whether arrangement of the smoking article 200
corresponds to correct arrangement. In the other example, the notification unit 179
provides notification if arrangement of the smoking article 200 corresponds to correct
arrangement, and does not provide notification if arrangement of the smoking article
200 does not correspond to correct arrangement. In any case, a user can easily check
whether arrangement of the smoking article 200 corresponds to correct arrangement.
(Flow of Process)
[0073] Fig. 5 is a flow chart showing an example of a flow of a heating control process
performed in the inhaler 100 according to the present embodiment. At the time when
the heating control process relating to the above flow is started, the operation mode
of the inhaler 100 is the sleep mode. In the case that the mode is the standby mode,
the process starts from step S106.
[0074] First, as shown in Fig. 5, the control unit 180 monitors a state as to whether the
power source switch 173 has been pressed (step S102). If the power source switch 173
is pressed (step S102 / YES), the control unit 180 starts supplying of electric power
from the battery 178 to the pressure sensor 177 (step S104). On the other hand, if
the power source switch 173 is not pressed (step S102 / NO), the process returns to
step S102 again. After step S104, the control unit 180 obtains result of detection
of pressure by the pressure sensor 177 (step S106). Next, the control unit 180 specifies,
based on the result of detection of pressure by the pressure sensor 177, arrangement
of the smoking article 200 in the inner space of the holding part 175 (step S108).
If it is judged that arrangement of the smoking article 200 corresponds to correct
arrangement (step S110 / YES), the control unit 180 changes the state with respect
to supplying of electric power to the heating unit 176 to a state that allows supplying
of electric power (step S112). On the other hand, if it is judged that arrangement
of the smoking article 200 does not correspond to correct arrangement (step S110 /
NO), the control unit 180 changes the state with respect to supplying of electric
power to the heating unit 176 to a state that does not allow supplying of electric
power (step S114). Thereafter, the process returns to step S110 again. After step
S112, the control unit 180 judges whether the power source switch 173 has been pressed,
and whether a suction action has been detected (step S116). If it is judged that the
power source switch 173 has been pressed or a suction action has been detected (step
S116 / YES), the control unit 180 performs supplying of electric power to the heating
unit 176 to start heating of the smoking article 200 (step S118). Thereafter, the
process is terminated. On the other hand, if it is judged that the power source switch
173 has not been pressed and a suction action has not been detected (step S116 / NO),
the process returns to step S116 again.
(Effect)
[0075] As explained above, only when arrangement of the smoking article 200 in the holding
part 175 corresponds to correct arrangement, supplying of electric power to the heating
unit 176 is performed. That is, even if the smoking article 200 is inserted in the
holding part 175, supplying of electric power to the heating unit 176 is not performed
if arrangement of the smoking article 200 does not correspond to correct arrangement.
Accordingly, occurrence of uneven heating and heating without an object to be heated
can be prevented in a precise manner. Further, since judgment as to whether arrangement
corresponds to correct arrangement is performed automatically by using a pressure
sensor, convenience of a user can be raised.
(Supplement)
[0076] The inhaler 100 may comprise an additional pressure sensor positioned between the
pressure sensor 177 and the heating unit 176 shown in Fig. 4. It is desirable that
the longitudinal-direction length from the bottom part 175a of the holding part 175
to the position where the additional pressure sensor detects pressure be shorter than
the longitudinal-direction length L
T-A of the base-material part 200A. In such a case, if arrangement of the smoking article
200 corresponds to the correct arrangement, the base-material part 200A positions
on the position where the additional pressure sensor detects pressure. The control
unit 180 specifies that arrangement of the smoking article 200 corresponds to the
correct arrangement, if pressure corresponding to hardness of the suction opening
part 200B is detected by the pressure sensor 177 and pressure corresponding to hardness
of the base-material part 200A is detected by the additional pressure sensor. Thus,
in the case that the smoking article 200 is inserted to reach an excessively deep
position so that the suction opening part 200B is inserted to be positioned on the
position of the additional sensor, it is possible to specify that the above arrangement
of the smoking article 200 does not correspond to correct arrangement.
<< 3. Second Embodiment >>
[0077] The present embodiment has a form wherein a pressure sensor is positioned in an upstream-side
end part of a holding part, and arrangement of a flavor component generating base-material
in the holding part is specified based on result of detection by the pressure sensor.
In the following description, explanation of parts shared by the present embodiment
and the first embodiment will be omitted, and parts of the present embodiment different
from those of the first embodiment will be explained mainly.
(Construction Example)
[0078] Fig. 6 is a block diagram showing an example of a schematic construction of an inhaler
100 in the state that it is holding a smoking article 200, according to a second embodiment.
As shown in Fig. 6, the inhaler 100 according to the present embodiment comprises
components similar to those in the inhaler 100 according to the first embodiment that
has been explained with reference to Fig. 4. In this regard, the construction of the
pressure sensor 177 in the present embodiment is different from that in the first
embodiment.
[0079] The pressure sensor 177 detects pressure applied to an inner wall of the holding
part 175. In the present embodiment, the pressure sensor 177 detects pressure applied
to an inner wall which is a part in the inner wall of the holding part 175 and is
positioned in the end part in the inserting direction. In the example shown in Fig.
6, the pressure sensor 177 detects pressure added to the bottom part 175a of the holding
part 175. In this regard, the bottom part 175a according to the present embodiment
may be constructed as a piston member which can move in the inserting direction. The
back side of the bottom part 175a is provided with a columnar convex part 175b which
extends in the inserting direction. An elastic member 175c is constructed, for example,
by using a compression coil spring, which is installed to surround the periphery of
the convex part 175b, is compressed in the inserting direction, and exerts elastic
force in the pulling-out direction. In the state that the smoking article 200 has
been inserted into the holding part 175 and the tip 210a has been brought into contact
with the bottom part 175a, if the smoking article 200 is further inserted, the bottom
part 175a moves, in the inserting direction, from an initial position. Thereafter,
if the smoking article 200 is pulled out from the holding part 175, the bottom part
175a is pushed back in the pulling-out direction by the elastic member 175c, and returns
to the initial position. The construction of the piston member is not limited to that
shown in Fig. 6, if movement such as that explained above can be realized.
(Operation)
[0080] The only difference between the operation of the inhaler 100 according to the present
embodiment and that in the first embodiment resides in the process for specifying
arrangement. In the following description, the above point will be explained in detail.
[0081] The control unit 180 according to the present embodiment specifies that arrangement
of the smoking article 200 corresponds to correct arrangement, if pressure representing
a state that the distance of movement of the bottom part 175a in the inserting direction
has reached a predetermined threshold value is detected by the pressure sensor 177.
In an example, the pressure sensor 177 may be connected to the elastic member 175c.
In such a case, the control unit 180 specifies that arrangement of the smoking article
200 corresponds to correct arrangement, if pressure added to the pressure sensor 177
from the elastic member 175c has reached a predetermined threshold value. In the other
example, the pressure sensor 177 may be installed in a position where the convex part
175 is brought in contact with the pressure sensor 177 when the distance of movement
of the bottom part 175a in the inserting direction has reached a predetermined threshold
value. In such a case, the control unit 180 specifies that arrangement of the smoking
article 200 corresponds to correct arrangement, if an event that the convex part 175b
is in contact with the pressure sensor 177 is detected. In this regard, regarding
the construction for detecting the contact state, a contact sensor may be installed
in place of the pressure sensor 177. On the other hand, the control unit 180 specifies
that arrangement of the smoking article 200 does not correspond to correct arrangement,
if pressure representing a state that the distance of movement of the bottom part
175a in the inserting direction has reached a predetermined threshold value is not
detected by the pressure sensor 177.
(Flow of Process)
[0082] The flow of the process in the inhaler 100 according to the present embodiment is
similar to that according to the first embodiment.
(Effect)
[0083] According to the present embodiment, since the pressure sensor 177 is installed in
a position distant from the holding part 175, effect of heat from the heating unit
176 on the pressure sensor 177 can be further suppressed, compared with the case of
the first embodiment. Thus, it becomes possible to further prevent failure of the
pressure sensor 177 due to heat.
<< 4. Third Embodiment >>
[0084] The present embodiment has a form wherein an elastic member is positioned in a downstream-side
end part of a holding part, and pressure added to the elastic member is detected by
a pressure sensor. In the following description, explanation of parts shared by the
present embodiment and the first embodiment will be omitted, and parts of the present
embodiment different from those of the first embodiment will be explained mainly.
(Construction Example)
[0085] Fig. 7 is a block diagram showing an example of a schematic construction of an inhaler
100 in the state that it is holding a smoking article 200, according to a third embodiment.
As shown in Fig. 7, the inhaler 100 according to the present embodiment comprises
an elastic member 181, in addition to components similar to those in the inhaler 100
according to the first embodiment that has been explained with reference to Fig. 4.
[0086] The elastic member 181 is installed in a position, in the inner wall of the holding
part 175, that is closer to the side of the opening 172a than the position heated
by the heating unit 176. For example, in the downstream-side end part of the holding
part 175, the elastic member 181 further protrudes from the inner wall of the holding
part 175 to the inner-space side, and is constructed in such a manner that the inner
diameter of the inner space in the protruded part is smaller than the outer diameter
of the smoking article 200. Further, the elastic member 181 holds the smoking article
200 by applying pressure from the periphery of the smoking article 200 inserted into
the inner space of the holding part 175. The elastic member 181 is constructed by
using any material such as rubber, sponge, or the like, for example. According to
the above construction, positioning of the smoking article 200 can be made easier,
and shifting of arrangement of the smoking article 200 out of correct arrangement
can be prevented more strongly.
[0087] The pressure sensor 177 detects pressure applied to the elastic member 181. For example,
the pressure sensor 177 may be an elastic gauge which detects pressure, based on deformation
of the elastic member 181. The pressure, that is applied to the elastic member 181
when the elastic member 181 holds the smoking article 200 by applying pressure to
the periphery of the smoking article 200, is detected by the pressure sensor 177.
The pressure sensor 177 is also be able to detect attachment/detachment of the smoking
article 2300 to/from the inhaler 100, based on judgment as to whether the detected
pressure is equal to or greater than a predetermined threshold value.
(Operation)
[0088] The operation of the inhaler 100 according to the present embodiment is similar to
that according to the first embodiment.
(Flow of Process)
[0089] The flow of the process in the inhaler 100 according to the present embodiment is
similar to that according to the first embodiment.
(Effect)
[0090] According to the present embodiment, the smoking article 200 is held by the elastic
member 181. Thus, compared with the case in the first embodiment, positioning of the
smoking article 200 can be made easier, and shifting of arrangement of the smoking
article 200 out of correct arrangement can be prevented more strongly.
<< 5. Fourth Embodiment >>
[0091] The present embodiment has a form wherein a plurality of function parts is installed,
and a function part which is to be activated is selected according to specified arrangement
of a flavor component generating base-material. In the following description, explanation
of parts shared by the present embodiment and the first embodiment will be omitted,
and parts of the present embodiment different from those of the first embodiment will
be explained mainly.
(Construction Example)
[0092] Fig. 8 is a block diagram showing an example of a schematic construction of an inhaler
100 in the state that it is holding a smoking article 200, according to a fourth embodiment.
As shown in Fig. 8, the inhaler 100 according to the present embodiment comprises
components similar to those in the inhaler 100 according to the first embodiment that
has been explained with reference to Fig. 4. However, the inhaler 100 according to
the present embodiment comprises a plurality of heating units 176 (a heating unit
176A and a heating unit 176B).
[0093] The plural heating units 176 are installed in different positions in the longitudinal
direction, respectively. For example, the distance L
H-A from the bottom part 175a of the holding part 175 to the position where the heating
unit 176A is installed is different from the distance L
H-B from the bottom part 175a of the holding part 175 to the position where the heating
unit 176B is installed. Further, the plural heating units 176 heat, from the different
positions in the longitudinal direction, respectively, the smoking article 200 held
by the holding part 175. It should be reminded that, although Fig. 8 shows an example
wherein two heating units 176 are installed, it may be possible to install three or
more heating units 176.
(Operation)
- Specifying of Arrangement
[0094] In the present embodiment, regarding the smoking article 200 in the part from one
end to the other end thereof in the longitudinal direction, the smoking article 200
has a part having hardness different from that of other parts. For example, the hardness
of the smoking article 200 gradually changes in the longitudinal direction. Change
in the hardness may be uniform increase or uniform decrease. For ensuring accuracy
of specifying of arrangement of the smoking article 200 that will be explained later,
it is desirable that positions in the smoking article 200 in the longitudinal direction
have one-to-one relationship with degrees of hardness.
[0095] The control unit 180 specifies arrangement of the smoking article 200 in the holding
part 175, by using difference in degrees of hardness of parts in the smoking article
200 from one end to the other end thereof in the longitudinal direction. In more detail,
the control unit 180 performs recognition with respect to the pressure detected by
the pressure sensor 177 for determining to which specific pressure corresponding to
a specific position in the smoking article 200 in the longitudinal direction the detected
pressure corresponds. Thereafter, the control unit 180 specifies the position of the
tip 210a of the smoking article 200 in the inner space of the holding part 175, based
on the distance L
I between the position P
I of the smoking article 200 corresponding to the pressure detected by the pressure
sensor 177 and the tip 210a of the smoking article 200.
- Control Corresponding to Specified Arrangement
[0096] The control unit 180 selects, from plural heating units 176, a heating unit 176 to
which electric power is to be supplied, based on the specified position of the tip
210a of the smoking article 200 in the inner space of the holding part 175. In more
detail, the control unit 180 selects, from the plural heating units 176, a heating
unit 176, to which electric power is to be supplied, which applies heat from a position
closer to the side of the opening 172a than the position of the tip 210a of the smoking
article 200. For example, the control unit 180 calculates, based on the distance L
I, a distance L
R between the tip 210a of the smoking article 200 and the bottom part 175a of the holding
part 175. Thereafter, the control unit 180 selects the heating units 176A and 176b
if the distance L
R is shorter than the distance L
H-B, selects the heating unit 176A if the distance L
R is equal to or longer than the distance L
H-B and shorter than L
H-A, and does not select any of the heating units if the distance L
R is equal to or longer than the distance L
H-A. In the example shown in Fig. 8, the distance L
R is equal to or longer than the distance L
H-B and shorter than L
H-A, so that the control unit 180 selects the heating unit 176A as that to which electric
power is to be supplied.
[0097] In this regard, after destination of supply of electric power is selected, the state
with respect to supplying of electric power to the heating unit 176, which is selected
as the destination of supply of electric power, is changed to a state that allows
supplying of electric power. On the other hand, the state with respect to supplying
of electric power to the heating unit 176, which is not selected as the destination
of supply of electric power, is changed to a state that does not allow supplying of
electric power.
[0098] As explained above, as result that a heating unit 176, which applies heat from a
position where the smoking article 200 is not being inserted, in the plural hearting
units 176 is not selected as a destination of supply of electric power, occurrence
of uneven heating and heating without an object to be heated can be prevented. Further,
as a result that a heating unit 176, which applies heat from a position where the
smoking article 200 is being inserted, in the plural hearting units 176 is selected
as a destination of supply of electric power, the smoking article 200 can be heated
to generate aerosol even in the case that the smoking article 200, although it is
being inserted, does not reach the innermost place of the holding part 175.
(Flow of Process)
[0099] Fig. 9 is a flow chart showing an example of a flow of a heating control process
performed in the inhaler 100 according to the present embodiment. At the time when
the heating control process relating to the above flow is started, the operation mode
of the inhaler 100 is the sleep mode. In the case that the mode is the standby mode,
the process starts from step S206.
[0100] The processes relating to steps S202-206 are similar to the processes relating to
steps S102-106 explained with reference to Fig. 5. As shown in Fig. 9, after step
S206, the control unit 180 specifies, based on result of detection of pressure by
the pressure sensor 177, a position of the tip 210a of the smoking article 200 in
the inner space of the holding part 175 (step S208). Next, based on the specified
position of the tip 210a of the smoking article 200, the control unit 180 selects
a heating unit 176, as a destination of supply of electric power, from the plural
heating units 176 (step S210). Next, the control unit 180 changes the state with respect
to supplying of electric power to the heating unit 176, that has been selected as
a destination of supply of electric power, to a state that allows supplying of electric
power (step S212). Next, the control unit 180 judges whether the power source switch
173 has been pressed, and whether a suction action has been detected (step S214).
If it is judged that the power source switch 173 has been pressed or a suction action
has been detected (step S214 / YES), the control unit 180 performs supplying of electric
power to the heating unit 176, which has been selected as a destination of supply
of electric power, to start heating of the smoking article 200 (step S216). Thereafter,
the process is terminated. On the other hand, if it is judged that the power source
switch 173 has not been pressed and a suction action has not been detected (step S214
/ NO), the process returns to step S214 again.
[0101] It should be reminded that the above explained flow of the process is an example,
and the present invention is not limited by the above example. For example, processes
relating to steps S212 and S214 may be omitted. In such a case, the inhaler 100 selects
a heating unit 176 as a destination of supply of electric power, and, right after
selection, performs supplying of electric power to the heating unit 176 selected as
a destination of supply of electric power.
(Effect)
[0102] According to the present embodiment, even in the case that the smoking article 200
does not reach the innermost place of the holding part 175 although it is being inserted
into the holding part 175, the smoking article 200 can be heated to generate aerosol
while preventing occurrence of uneven heating or heating without an object to be heated.
<< 6. Modified Examples >>
< 6.1. First Modified Example >
[0103] In each of the above embodiment, judgment as to whether arrangement of the smoking
article 100 corresponds to correct arrangement is made based on result of detection
of pressure by the pressure sensor; however, the present invention is not limited
by the above embodiments. For example, judgment as to whether arrangement of the smoking
article 100 corresponds to correct arrangement may be made by using a physical mechanism.
In the following description, the above point will be explained in detail.
(Construction Example)
[0104] Fig. 10 is a figure schematically showing a procedure to insert a smoking article
200 into an inhaler 100 according to a first modified example. An insertion procedure
proceeds in accordance with step S302 to step S306. Step S302 shows a state before
insertion. Step S304 shows a state during an inserting process. Step S306 shows a
state after completion of insertion.
[0105] As shown in step S302, the smoking article 200 according to the present modified
example comprises, in addition to the base-material part 200A and the suction opening
part 200B, a stick holder 200C that is installed to cover the tip 210a of the base-material
part 200A. The stick holder 200C comprises an elastic member 211 which protrudes in
a transverse direction of the smoking article 200. In this regard, the transverse
direction is a direction orthogonal to the longitudinal direction, so that, for example,
if the shape of the cross section of the stick holder 200C is circular, the transverse
direction is a radial direction. The elastic member 211 is constructed by using an
elastic member such as rubber or the like, for example, to have a columnar shape extending
in the transverse direction, and exerts elastic force in a direction orthogonal to
the transverse direction.
[0106] The holding part 175 according to the present modified example comprises a groove
part 182 along which the elastic member 211 can slide when the smoking article 200
is inserted or pulled out. The groove part 182 is formed in the inner wall of the
holding part 175. The smoking article 200 is inserted into the holding part 175 after
the position of a gate 182A of the groove part 182 formed in the opening 172a and
the position of the elastic member 211 are aligned with each other. The elastic member
211 slides along the inside of the groove part 182 in the inserting direction when
the smoking article 200 is inserted, and slides along the inside of the groove part
182 in the pulling-out direction when the smoking article 200 is pulled out. Hereinafter,
the axis passing through the gate 182A and extending in the longitudinal direction
is also referred to as a central axis 182B. As shown in Fig. 10, the groove part 182
is bent toward the direction of the circumference of the inner space of the holding
part 175. In a section wherein position shift d from the position of the gate 182A
in the circumferential direction (i.e., position shift from the central axis 182B
in the circumferential direction) exceeds 0, the elastic member 211 is in a state
that it is being bent in the circumferential direction and the tip thereof slides
along the inside of the groove part 182. In the above state, the elastic member 211
exerts elastic force that works to move it back in the direction toward the central
axis 182B. The groove part 182 comprises a first end 183 (183A and 183B) positioned
in the inserting direction, and a second end 184 positioned between the first end
183 and the opening 172a and in the pulling-out direction. Further, the inhaler 100
comprises an elastic member 185 which exerts, to the smoking article 200, elastic
force in the pulling-out direction. The elastic member 185 is constructed by using
a compression coil spring or the like, for example.
[0107] As shown in step S304, when the smoking article 200 is inserted in the inserting
direction by a hand of a user, the elastic member 185 is compressed while the smoking
article 200 is being inserted. At the time when the inserted smoking article 200 has
reached the innermost place, the elastic member 211 reaches the first end part 183.
At that time, the position shift d
1 in the circumferential direction between the gate 128A and the first end part 183
is large, compared with the position shift d
2 in the circumferential direction between the gate 128A and the second end part 184.
In the example shown in Fig. 10, it is shown that d
1>0 and D
2=0. Thus, in the state that the elastic member 211 has reached the first end part
183, the elastic member 211 exerts elastic force that works to move it back in the
direction toward the central axis 182B. In the above state, if a user takes a user's
hand off the smoking article 200, the elastic member 211 attempts to move back in
the direction toward the central axis 182B, i.e., exerts elastic force that works
to move it in the direction toward the second end part 184, with respect to which
the position shift from the central axis 182B is smaller. As a result, the elastic
member 211 slides along the inside of the groove part 182 from the first end part
183 to the second end part 184, and, by the elastic force exerted from the elastic
member 185 while it is sliding, the smoking article 200 is pushed back in the pulling
out direction. Thereafter, when the elastic member 211 has reached the second end
par 184, pushing-back action in the pulling out direction is terminated. In this regard,
in the case that the tip part, which is to be in contact with the groove part 182,
of the elastic member 211 is covered by a metal or the like, sound of collision may
be generated when the elastic member 211 (the tip part thereof) collides, as a result
of pushing-back, with the second end part 184.
[0108] Step S306 shows a state that the elastic member 211 has been pushed back and has
reached the second end part 184. The correct arrangement of the smoking article 200
according to the present modified example refers to the state shown in step S306.
[0109] On the other hand, when pulling out the smoking article 200, a user once pushes it
until the elastic member 211 reaches the first end part 183. Thereafter, the user
pulls out the smoking article 200 in such a manner that, while it is being pulled
out, it is rotated in a direction along that the elastic member 211 is moved away
from the central axis 182B. In this manner, the smoking article 200 can be pulled
out from the holding part 175.
(Effect)
[0110] According to the present modified example, a user inserts the smoking article 200
in the inserting direction by a user's hand, and, thereafter, can recognize that arrangement
of the smoking article 200 corresponds to correct arrangement, when action that the
elastic member 211 is pushed back until it reaches the second end part 184 is completed.
More simply, a user can also recognize that arrangement of the smoking article 200
corresponds to correct arrangement, by hearing sound of collision between the elastic
member 211 and the second end part 184. Further, according to the present modified
example, it becomes possible to prevent unsatisfactory insertion of the smoking article
200, so that occurrence of uneven heating and heating without an object to be heated
can be prevented.
(Supplement 1)
[0111] It should be reminded that the inhaler 100 according to the present modified example
may comprise a pressure sensor 177. For example, the pressure sensor 177 may be installed
in a manner explained in relation to each of the above embodiments, and arrangement
of the smoking article 200 may be specified thereby. In the other example, a pressure
sensor 177 may be installed in the second end part 184, and arrangement of the smoking
article 200 may be specified based on result as to whether the state that the elastic
member 211 has reached the second end part 184 is detected by the pressure sensor
177. Further, a process corresponding to specified arrangement of the smoking article
200 may be performed.
(Supplement 2)
[0112] Further, although an example in which the stick holder 200C is installed on the smoking
article 200 is illustrated in Fig. 10, the present invention is not limited by the
above example. For example, the stick holder 200C may not be installed on the smoking
article 200, and may be installed, in the inhaler 100, as a sliding member which slides
in the inner space of the holding part 175. Such a sliding member is installed in
the inner space of the holding part 175 in such a manner that it can slide, along
an inner wall of the holding part 175, in the inner space of the holding part 175.
Similar to the stick holder 200C shown in Fig. 10, the sliding member comprises an
elastic member 211 protruding in the transverse direction in the inner space of the
holding part 175. In this regard, the transverse direction is a direction orthogonal
to the longitudinal direction, so that, for example, if the shape of the cross section
of the inner space of the holding part 175 is circular, the transverse direction is
a radial direction.
[0113] Other constructions are similar to those shown in Fig. 10. For example, the holding
part 175 comprises a groove part 182 along which the elastic member 211 can slide
when the sliding member slides. The sliding member slides in the inner space of the
holding part 175 in the inserting direction or the pulling-out direction when the
smoking article 200 is inserted or pulled out. In conjunction with the above sliding,
the elastic member 200 slides along the inside of the groove part 182 in the inserting
direction when the smoking article 200 is inserted, and slides along the inside of
the groove part 182 in the pulling-out direction when the smoking article 200 is pulled
out. The groove part 182 comprises a first end 183 and a second end 184. Further,
the inhaler 100 comprises an elastic member 185 which exerts, to the sliding member,
elastic force in the pulling-out direction.
[0114] The inserting/pulling-out procedure for inserting/pulling-out the smoking article
into/from the inhaler 100 is also similar to that explained above with reference to
Fig. 10. However, in the inserting procedure, the smoking article 200 is inserted
into the holding part 175 in such a manner that the sliding member is pushed by the
tip of the smoking article 200 and the sliding member slides in the inserting direction.
A user can insert the smoking article 200 with sliding movement of the sliding member
in the inserting direction. On the other hand, in the pulling-out procedure, the elastic
member 185 exerts elastic force in the pulling-out direction, that is applied to the
sliding member, to push the sliding member back to a position in the pulling-out direction
in the holding part 175. In relation to the above action, the user can pull out the
smoking article 200 from the holding part 175.
[0115] According to the present construction, since it is unnecessary for the smoking article
200 to have the stick holder 200C, the cost required for manufacturing the smoking
article 200 can be reduced, compared with that in the case of the construction in
which the smoking article 200 has the stick holder 200C.
< 6.1. Second Modified Example >
[0116] Regarding each of the above embodiments, although an example in which the smoking
article 200 is inserted from the opening 172a into the inner space of the holding
part 175 has been explained, the present invention is not limited by the above example.
In the following description, the other example will be explained.
(Construction Example)
[0117] Fig. 11 is a figure showing a schematic construction example of an inhaler 100 according
to a second modified example. As shown in Fig. 11, the holding part 175 according
to the present modified example comprises a first housing 190A and a second housing
190B which can be separated from or coupled to each other. For example, the first
housing 190A is coupled to the second housing 190B via a rotation axis 191, and can
be rotated about the rotation axis 191 as the center of rotation. Thus, the first
housing 190A and the second housing 190B are separated by rotating them in a direction
for separating them from each other, and are coupled with each other by rotating them
until they are brought to be in contact with each other. It should be reminded that,
in Fig. 11, illustration of the constructions of the heating unit 176 and so on are
omitted.
[0118] For inserting the smoking article 200 into the inhaler 100, first, the first housing
190A and the second housing 190B are brought to a state wherein they are separated
from each other, and the smoking article 200 is put in a groove part 192 in the second
housing 190B. While maintaining the above state, the first housing 190A is rotated
until it is brought to be in contact with the second housing 190B, and is fixed during
the contact state, and, as a result, the first housing 190A and the second housing
190B are coupled with each other. The holding part 175 holds the smoking article 200
between the first housing 190A and the second housing 190B which are in a state that
they are being coupled with each other. For example, a pressure sensor 177 is installed
in the groove part 192 in the second housing 190B, and detects pressure applied thereto
when the smoking article 200 is held between the housings.
(Supplement)
[0119] It should be reminded that arrangement of the smoking article 200 may be specified
based on result of detection by the pressure sensor and by using the method explained
in relation to each of the above embodiments. Further, a process corresponding to
specified arrangement of the smoking article 200 may be performed.
<< 7. Conclusion >>
[0120] Embodiments of the present invention have been explained in detail with reference
to Figs. 1-11. As explained above, according to each embodiment, the inhaler 100 comprises
a holding part for holding the smoking article 200 in the internal space, and a pressure
sensor 177 for detecting pressure applied to the inner wall of the holding part 175.
Further, the inhaler 100 specifies, based on result of detection by the pressure sensor
177, arrangement of the smoking article 200 in the holding part 175. In addition to
judgment as to whether the smoking article 200 has been inserted into the holding
part 175, the inhaler 100 can specify whether arrangement of the smoking article 200
in the holding part 175 corresponds to correct arrangement. Further, since the pressure
sensor 177 is not affected by ambient light, accuracy of detection can be improved,
compared with the case that a light sensor is used.
[0121] In the above description, preferred embodiments of the present invention have been
explained in detail with reference to the attached figures; however, the present invention
is not limited by the examples explained above. It is obvious to a person, who has
ordinary skill in the technical field to which the present invention pertains, that
it is possible to conceive of various kinds of modified examples or rectified examples
within the scope of the technical idea disclosed in the claims; and it is understood
that they are also those pertaining to the scope of the technique of the present invention.
[0122] For example, regarding each of the above embodiments, it has been explained that
arrangement of the smoking article 200 in the holding part 175 refers to arrangement
of the smoking article 200 inserted into the inner space of the holding part 175 in
the longitudinal direction; however, the present invention is not limited to the above
example. For example, arrangement of the smoking article 200 in the holding part 175
may refer to an angle of the smoking article 200 inserted into the inner space of
the holding part 175. In this regard, the angle of the smoking article 200 is an angle
formed between an axis in the longitudinal direction of the inhaler 100 and an axis
in the longitudinal direction of the smoking article. For example, plural pressure
sensors 177 are installed side by side in the longitudinal direction in the inner
wall of the holding part 175, and the angel of the smoking article 200 is specified
based on a slope with respect to values of pressure detected by the plural pressure
sensors 177.
[0123] Further, each of the above-explained embodiments may be combined with the other embodiment
in an appropriate manner. For example, the first embodiment may be combined with the
second embodiment. In such a case, pressure sensors are installed in both the downstream-side
end part and the upstream-side end part of the holding part, and arrangement of the
flavor component generating base-material in the holding part is specified based on
result of detection by these pressure sensors. In the above case, accuracy with respect
to specifying of arrangement of the flavor component generating base-material can
be improved, compared with the case wherein one of the pressure sensors only is installed.
[0124] It should be reminded that the inhaled 100 explained in this specification may be
realized as a single device, or a device comprising a different device as a component
thereof or comprising different devices as components constituting the device. For
example, in the functional constructions in the inhaler 100 explained with reference
to Fig. 4 and so on, the control unit 180 may be installed in a control device, that
is for the inhaler 100, in a smart phone, a server, of the like which is connected
to the inhaler 100 via a network or the like. In the above case, the inhaler 100 transmits
result of detection by the pressure sensor 177 to the control device. Next, the control
device specifies arrangement of the smoking article 200 based on the result of detection
by the pressure sensor 177, generates control information (for example, an instruction
to start heating by the heating unit 176) corresponding to the specified arrangement,
and transmits the generated control information to the inhaler 100. Thereafter, the
inhaler 100 performs a process instructed in the control information received from
the control device.
[0125] It should be reminded that the series of processes performed by the respective devices
explained in the present specification may be realized by using any one of software,
hardware, and a combination of software and hardware. Programs, that are components
of the software, are stored in advance in a storage medium (a non-transitory medium:
a non-transitory media) implemented in the inside or the outside of the respective
devices, for example. Further, for example, each program is read into a RAM when a
computer is operated, and is executed by a processor such as a CPU. The above storage
medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk,
a flash memory, or the like. Further, the above-explained computer program may be
delivered via a network without using a storage medium, for example.
[0126] Further, the processes explained by using each of the flow charts and sequence diagrams
in the present specification may not necessarily be performed in the illustrated order.
Some processing steps may be performed in a parallel manner. Further, an additional
processing step may be adopted, and some processing steps may be omitted.
