BACKGROUND
[0002] In the related art, an electronic atomization device is usually configured to heat
and atomize cigarette liquid stored therein, and form atomized gas for a user to inhale.

flow channel of the electronic atomization device. When the atomized air enters the
air outlet channel, the atomized gas will partially condense when it meets a side
wall of the air outlet channel to form a condensate. The condensate will easily enter
an atomization cavity by gravity and leak out from a bottom of the atomization cavity
to an outside of a housing. In addition, the cigarette liquid in an atomization element
in the atomization cavity may also leak from the bottom of the atomization cavity
to the outside of the housing, resulting in a poor user experience.

[0029] FIGS. 1 to 4 show a first embodiment of the electronic atomization device of the
present disclosure. The electronic atomization device is applied to an atomization
of liquid medium such as atomization cigarette liquid and medicine. The electronic
atomization device includes an atomizer and a power supply device mechanically and
electrically connected to the atomizer. The atomizer is configured for heating and
atomizing the liquid medium, and the power supply device is configured for powering
the atomizer. In some embodiments, the atomizer and the power supply device are detachably
connected. The power supply device includes a power supply case; a battery arranged
in the power supply case; a conductive contact arranged in the power supply case,
connected to the battery, and connected to the atomizer; and a control circuit arranged
in the power supply case and electrically connected to the battery and the atomizer.
[0030] As shown in FIGS. 3 to 7, in the embodiments, the atomizer includes a housing 10,
a base 20, an atomization assembly 30, a first sealing member 40, an air-liquid balancing
element 50, and a liquid guiding element 60. The housing 10 is sleeved on a periphery
of the atomization assembly 30, and an inner side of the housing 10 is configured
to define a liquid storage cavity 111 for accommodating the liquid medium. In the
embodiments, the liquid medium is cigarette liquid. The base 20 is configured for
an installation of the atomization assembly 30, and the housing 10 is sleeved on the
base 20. The atomization assembly 30 is arranged in the housing 10 and on the base
20. The first sealing member 40 is arranged on the base 20 and is configured to seal
a connection between the atomization assembly 30 and the base 20. The air-liquid balancing
element 50 is arranged in a main body 11 at a lower part of the liquid storage cavity
111, is sleeved on the periphery of the atomization assembly 30, and is arranged on
the base 20. The air-liquid balancing element 50 connects the liquid storage cavity
111 with the outside, so as to balance the air pressure in the liquid storage cavity
211. The number of the liquid guiding elements 60 may be two. It can be understood
that in other embodiments, the number of the liquid guiding elements 60 may be one
or more. The liquid guiding element 60 is inserted through the air-liquid balancing
element 50, and is configured to connect the liquid storage cavity 111 with the atomization
assembly 30 for providing liquid medium to the atomization assembly 30. It can be
understood that in other embodiments, both the air-liquid balancing element 50 and
the liquid guiding element 60 may be omitted.
[0031] Further, in the embodiment, the housing 10 includes a main body 11 and an air outlet
tube 12. The main body 11 and the air outlet tube 12 are integrally formed by injection
molding. It can be understood that in other embodiments, the air outlet tube 12 and
the main body 11 are separate structures. The main body 11 is sleeved on the base
20 and the atomization assembly 30, and a space is defined within the main body 11
above the atomization assembly 30. The space is configured to define the liquid storage
cavity 111. The air outlet tube 12 is longitudinally arranged in the main body 11
and is connected to the atomization assembly 30. The air outlet tube 12 is arranged
at a central axis of the body 11. It can be understood that in other embodiments,
the air outlet tube 12 is arranged on a side of the main body 11 and is not limited
to the central axis. The air outlet tube 12 may also be arranged obliquely. An air
outlet channel 121 is defined on an inner side of the air outlet tube 12, and the
air outlet channel 121 is arranged along an axial direction of the air outlet tube
12. A side wall of the air outlet channel 121 is integrally formed with the housing.
When a user inhales, an atomized gas may reach the mouth of the user through the air
outlet channel 121. A second end 1212 of the air outlet channel 121 is inserted into
the atomization assembly 30, and a first end 1211 of the air outlet channel 121 forms
a cigarette holder for the user to inhale the atomized gas. At least one first liquid
absorbing groove 122 is defined on an inner side wall of the air outlet channel 121.
In the embodiments, the number of the at least one first liquid absorbing groove 122
may be more than one. In some embodiments, the number of the first liquid absorbing
grooves 121 is not limited to multiple, and it may also be one. The first liquid absorbing
groove 122 has a capillary function, which is configured to suck the condensate formed
by condensation on the side wall of the air outlet channel 121. The condensate flows
to the atomization assembly 30 under the action of gravity. The atomization assembly
30 atomizes the condensate flowing down from the first liquid absorbing groove 122
again, thereby improving the utilization rate of the liquid medium.
[0032] Further, in the embodiments, the plurality of first liquid absorbing grooves 122
are arranged on an inner side wall of the air outlet tube 12 and are arranged at intervals
along the air outlet channel 121 in a circumferential direction. When the atomized
gas reaches an air outlet through the air outlet channel 121, airflow around the air
outlet channel 121 meets the inner side wall of the air outlet tube 12 to condense
to form the condensate. At this time, the first liquid absorbing groove 122 may suck
the condensate in by capillary function. In the embodiment, the first liquid absorbing
groove 122 is arranged along a longitudinal direction of the air outlet channel 121,
and extends from the second end 1212 of the air outlet channel 121 toward the first
end 1211 of the air outlet channel 121. The first liquid absorbing groove 122 is parallel
to the central axis of the air outlet channel 121 and is connected to the atomization
assembly 30 in a liquid conducting manner, such that the condensate flows to the top
of the atomization assembly 30 in the direction of the first liquid absorbing groove
122 under the action of gravity and drops on the atomization assembly 30 to be atomized
again, thereby improving the utilization rate of the liquid medium, and preventing
the liquid medium from being inhaled into the user's mouth, thus improving the user
experience. In the embodiments, the first liquid absorbing groove is not limited to
being arranged longitudinally, and it may be arranged spirally or inclined.
[0033] In the embodiments, an outlet 1221 is defined on an end surface of the first end
1211 of the air outlet channel 121. The outlet 1221 is in communication with the first
liquid absorbing groove 122 and is in communication with the atomization assembly
30. The liquid in the first liquid absorbing groove 122 may drop onto the atomization
assembly 30 through the outlet 1221.
[0034] In the embodiments, the depth of the first liquid absorbing groove 122 is gradually
reduced along the direction away from the outlet 1221. A bottom surface of the first
liquid absorbing groove 122 is a slope inclined toward the direction of the outlet
1221. In this way, an upper part of the first liquid absorbing groove 122 stores less
liquid, and a lower part of the first liquid absorbing groove 122 stores more liquid,
thereby preventing the liquid in the upper part of the first liquid absorbing groove
122 from being inhaled into the user's mouth. The bottom surface of the first liquid
absorbing groove 122 is set as an inclined surface inclined toward the direction of
the outlet 1221, thereby increasing the resistance of the lower liquid to be sucked
out, further preventing the liquid from being inhaled into the user's mouth. Specifically,
in the embodiments, the depth of each first liquid absorbing groove 122 may be greater
than or equal to 0.1 mm. In the embodiments, the width of each first liquid absorbing
groove 122 is gradually increased along the opening direction of the first liquid
absorbing groove 122, such that the first liquid absorbing groove 122 has a narrow
inside and a wide opening. This feature further facilitates the flow of liquid to
the atomization assembly 30 along the first liquid absorbing groove 122. In the embodiments,
the width of each liquid storage groove 122 may be 0.05-1 mm.
[0035] As shown in FIGS. 4 to 8, in the embodiments, the base 20 includes a base body 21,
a support assembly 22 arranged on the base body 21, and a liquid storage structure
23. The shape and size of a cross-section of the base body 21 are adapted to the shape
and size of an opening end of the housing 10. The base body 21 is configured to block
the opening of the housing 10. The base 20 defines a groove 211. Specifically, the
groove 211 is defined on a side of the base body 21 opposite to an atomization cavity
311 of the atomization assembly 30, thereby forming the liquid storage structure 23
at the bottom of the atomization cavity 311. The support assembly 22 includes two
sets of support pillars arranged at intervals. The two sets of support pillars are
arranged on two opposite sides of the groove 211, which are configured to support
an atomization element 32 of the atomization assembly 30. The liquid storage structure
23 is arranged in the groove 211 and communicates with the atomization cavity 311
of the atomization assembly 30. The liquid storage structure 23 is configured to store
the liquid medium and prevent the liquid medium from leaking.
[0036] Further, in the embodiments, the liquid storage structure 23 includes a plurality
of second liquid absorbing grooves 231, a branch groove 232, and a plurality of guide
grooves 233. The plurality of second liquid absorbing grooves 231 are arranged side
by side and spaced at a bottom of the groove 211. The plurality of second liquid absorbing
grooves 231 are arranged opposite to the atomization cavity 311, which have a capillary
function and can suck from the liquid medium dropping from the atomization cavity
311 or the air outlet channel 121. The number of the second liquid absorbing grooves
231 is not limited to multiple, and it may be one. The branch groove 232 is arranged
on the bottom surface of the groove 211 and is intersected with the plurality of second
liquid absorbing grooves 231. The branch groove 232 crosses and communicates with
the second liquid absorbing grooves 231, thereby achieving diversion and enabling
faster suction of the liquid medium. The plurality of guide grooves 233 are arranged
on a side wall of the groove 211 at intervals, are arranged corresponding to the second
liquid absorbing grooves 231 and the branch groove 232, and are connected to the second
liquid absorbing grooves 231 and the branch groove 232. The plurality of guide grooves
233 have a capillary function and are configured to pour liquid into the second liquid
absorbing grooves 231.
[0037] Further, in the embodiments, each second liquid absorbing groove 231 extends laterally
along the bottom surface of the groove 211, that is, extends laterally along the atomization
cavity 311. In this way, the flow direction of the liquid medium may be controlled,
thereby effectively preventing liquid leakage. In the embodiments, the width of each
second liquid absorbing groove 231 is 0.05-1 mm, and the depth of each second liquid
absorbing groove 231 is greater than 0.1 mm. It can be understood that in other embodiments,
the depth of each second liquid absorbing groove 231 may be equal to 0.1 mm.
[0038] Further, in the embodiments, the branch groove 232 is perpendicular to each second
liquid absorbing groove 231 and divides each second liquid absorbing groove 231 into
two sections. The width of the branch groove 232 is greater than the width of each
second liquid absorbing groove 231, thereby increasing the liquid suction rate and
preventing the liquid medium from penetrating to the outside from an electrode pore.
[0039] Further, in the embodiments, the guide grooves 233 are arranged on the side wall
of the groove 211 and extend along the longitudinal direction of the base 20. Each
guide groove 233 communicates with a corresponding second liquid absorbing groove
231 and the branch groove 232. The guide grooves 233 are configured to guide the liquid
medium to the second liquid absorbing grooves 231 and the branch groove 232. In the
embodiments, an opening at an end of each guide groove 233 away from the corresponding
second liquid absorbing groove 231 and the branch groove 232 is arranged outside the
atomization cavity 311, which is configured to suck liquid leakage from the outside
of the atomization cavity 311. In the embodiments, a step 2111 is arranged on the
inner side wall of the groove 211, and the step is configured for mating and assembling
with an atomization shell 31 of the atomization assembly 30 to improve the compactness
of the assembly. In the embodiments, the guide grooves 233 have a capillary function,
which is configured to suck the leakage and cause the leakage to the second absorbing
grooves 231. In the embodiments, the width of each guide groove 233 may be 0.05-1
mm. It can be understood that in other embodiments, the width of each guide groove
233 is not limited to 0.05-1 mm.
[0040] Further, in the embodiments, the atomization assembly 30 includes an atomization
shell 31 and an atomization element 32. The atomization shell 31 is sleeved on the
base 20 and inserted into the groove 211. The atomization shell 31 is configured for
arranging and fixing the atomization element 32. An inner side of the atomization
shell 31 defines an atomization cavity 311. The atomization cavity 311 is arranged
on the upper part of the base 20 and is directly connected to the first liquid absorbing
groove 122. Liquid leakage is prone to occurring at the position at which the atomization
shell 31 contacts the atomization element 32, and the liquid medium is easy to leak
from the connection between a first sealing member 40 and the atomization shell 31.
The opening at the end of each guide groove 233 away from the corresponding second
liquid absorbing groove 231 and the branch groove 232 is arranged opposite to the
connection between the atomization shell 31 and the first sealing member 40. Specifically,
the opening directly faces the connection, which can suck the leakage by capillary
force. The atomization element 32 passes through the atomization shell 31 in a transverse
direction. The atomization element 32 includes an atomization core 321 passing through
the atomization shell 31 and a heating element 322 surrounding the atomization core
321. The atomization core 321 may be a cotton core. Two ends of the atomization core
321 are arranged on the two sets of support pillars on the base body 211 and are connected
to the liquid guiding element 60 for liquid guiding. A conductive connection part
of the heating element 322 penetrates the base 20 and is connected to an electrode
90. In the embodiments, the heating element 322 may be a heating wire.
[0041] Further, in the embodiments, the first sealing member 40 is sleeved on the base 20
and is sleeved on a periphery of the atomization shell 31. Specifically, the first
sealing member 40 may be a sealing sleeve. The sealing sleeve may be a silicone sleeve
or a rubber sleeve. It can be understood that in other embodiments, the sealing sleeve
is not limited to a silicone sleeve or a rubber sleeve.
[0042] Further, in the embodiments, the air-liquid balancing element 50 is cylindrical,
specifically, it is in a cylindrical shape with an oval or rectangular cross-section.
An outer circumference of the air-liquid balancing element 50 is combined with the
inner wall surface of the housing 10 by means of interference fit to seal the liquid
storage cavity 111. In the embodiments, the air-liquid balancing element 50 includes
two through holes 51, a liquid storage and air exchange structure 52 arranged on a
periphery of each through hole 51, and an air flow channel 53 arranged between the
two through holes 51. The liquid guiding elements 60 are inserted into the through
holes 51. The liquid storage and air exchange structure 52 is configured to communicate
the liquid storage cavity 111 with the outside to balance the air pressure in the
liquid storage cavity 111. The liquid storage and air exchange structure 52 includes
a plurality of liquid storage grooves 521 arranged side-by-side to generate capillary
force on the liquid medium and two air return grooves. The air return groove are configured
to store liquid to prevent leakage. The air return grooves are arranged in the longitudinal
direction, transversely cut the liquid storage grooves 521, and communicate with the
liquid storage grooves 521 and the liquid storage cavity 111, thereby supplying gas
into the liquid storage cavity 111. The air flow channel 53 communicates with the
air outlet channel 121 to facilitate the communication between the air outlet channel
121 and the atomization cavity 311. With the air-liquid balancing element 60, a temperature
ventilation process is formed, which prevents frying oil and burnt odor caused by
long-term non-ventilation (insufficient liquid supply), and prevents large-particle
droplets and liquid leakage phenomenon caused by sudden large-scale ventilation (excessive
liquid supply). Further, by forming an independent ventilation channel and sealing
the structural gap, the liquid leakage caused by capillary force of the gap and environmental
changes may be prevented, and leakage and condensate may be prevented from being inhaled,
thereby improving product yield.
[0043] Further, in the embodiments, each liquid guiding element 60 is arranged corresponding
to the through hole 51 on the air-liquid balancing element 50. The liquid guiding
elements 60 are inserted into the through holes 51 and are arranged at both ends of
the atomization core 321. The liquid guiding elements 60 are connected to the atomization
core 321 in a liquid conducting manner. The liquid guiding element 60 may be a cotton
core. It is understood that in other embodiments, the liquid guiding element 60 is
not limited to a cotton core.
[0044] Further, in the embodiments, the atomizer further includes a fixing sleeve 70 configured
for fixing the conductive connection part of the heating element 322 and for positioning
the conductive connection part of the heating element 322. The conductive connecting
part of the heating element 322 penetrates the fixing sleeve 70. The fixing sleeve
70 defines a through hole 71 communicating with the atomization cavity 311. The through
hole 71 is arranged in the longitudinal direction and communicates with the air outlet
channel 121 to facilitate gas circulation. In the embodiments, the fixing sleeve 70
may be a silicone sleeve. It can be understood that in other embodiments, the fixing
sleeve 70 may be omitted.
[0045] Further, in the embodiments, the atomizer further includes a second sealing member
80. The second sealing member 80 may be a sealing sleeve, which is sleeved on the
air-liquid balancing element 50. The second sealing member 80 defines relief holes
facing the liquid guiding element 60 and the air outlet channel 121. The second sealing
member 80 may be a silicone sleeve or a rubber sleeve.
[0046] Further, in the embodiments, the atomizer further includes an electrode 90. The electrode
90 includes two electrode columns. The two electrode columns are a positive electrode
column and a negative electrode column, which are arranged side by side on the base
body 211. For each electrode column, an end is connected to the conductive connection
part of the heating element 322 by a lead wire, and the other end is conductively
connected to the power supply device.
[0047] FIGS. 9-12 show a second embodiment of the atomizer of the present disclosure. The
present disclosure provides an atomizer, including: a base 20; a housing 10 sleeved
on the base 20, and sealed and connected to the base 20 to define a liquid storage
cavity 111; an electrode 90 arranged on a bottom of the base 20; a liquid injection
assembly 109 arranged on and penetrating the base 20 for filling the liquid storage
cavity 111; an atomizer body arranged on the base 20; an air flow channel running
through the entire atomizer; and a liquid absorbing structure 101. Among them, the
base includes a liquid storage structure, and the liquid storage structure refers
to the first embodiment, which will not be repeated here. The atomizer body includes
an atomization assembly 30, and the air flow channel includes an air inlet channel
131, an atomization cavity 311 and an air outlet channel 121. The liquid absorbing
structure 101 is arranged in the air outlet channel 121, and the liquid absorbing
structure 101 defines a plurality of liquid storage grooves 105 in a circumferential
direction. The liquid storage groove 105 sucks a condensate in the air outlet channel
121 and/or an incomplete atomized cigarette liquid carried out during an inhaling
process by capillary forces. In the embodiments, the material of the liquid absorbing
structure 101 is one or more of PETG, PCTG, and PC.
[0048] Specifically, the liquid absorbing structure 101 includes a plurality of fins 104.
The fins 104 are arranged at intervals in parallel along a longitudinal direction,
and a liquid storage groove 105 is defined between every two adjacent fins 104. The
width of the liquid storage groove 105 is small enough to generate a capillary force
on the condensate, such that in the smoke generated during the inhaling process, the
liquid droplets brought out by passing through the fin 104 structure will be trapped
in the liquid storage groove 105, and a liquid film is formed in the liquid storage
groove 105. In this way, the liquid droplets may be stored in the liquid storage groove
105 to prevent the leakage of liquid from being inhaled.
[0049] The atomization assembly 30 includes a cylindrical atomization core 321, a liquid
guiding cotton 323 surrounding the atomization core 321, and a heating element 322
wound on the atomization core 321. A conductive connection part of the heating element
322 penetrates the base 20 and is connected to the electrode 90. In some embodiments,
the heating element 322 may be a heating wire. When in use, the atomization core 321
sucks the cigarette liquid in the liquid storage cavity 111, and the heating element
322 is energized to generate heat, such that the cigarette liquid in the atomization
core 321 is atomized. The user inhales through an inhaling port of a top cover of
the atomizer. Air enters the atomization core 321 from the air inlet channel 131 under
the inhaling action, is mixed with the atomized cigarette liquid in the atomization
core 321, and is discharged from the inhaling port of the top cover of the atomizer
after passing through the air outlet channel 121.
[0050] In the embodiments, the liquid absorbing structure 101 includes a plurality of fins
104. The fins 104 are arranged in parallel or non-parallel at intervals along the
longitudinal direction, and a liquid storage groove 105 is defined between every two
adjacent fins 104. The width of the liquid storage groove 105 is small enough to generate
a capillary force on the condensate, such that in the smoke generated during the inhaling
process, the liquid droplets brought out by passing through the fin 104 structure
will be trapped in the liquid storage groove 105, and a liquid film is formed in the
liquid storage groove 105. In this way, the liquid droplets may be stored in the liquid
storage groove 105 to prevent the leakage of liquid from being inhaled. The thickness
of the fin 104 and the width of the liquid storage groove 105 are 0.1-0.5 mm, and
in some embodiments 0.15-0.3 mm.
[0051] In order to prevent that too much cigarette liquid accumulated in the liquid storage
groove 105 in the liquid absorbing structure 101 will be taken out along with the
inhaling, in the embodiments, the liquid absorbing structure 101 includes: at least
one return groove 106 extending in the longitudinal direction. At least one return
groove 106 longitudinally intersects with at least part of the liquid storage groove
105. When the liquid storage groove 105 accumulates too much cigarette liquid, the
cigarette liquid may flow back to the atomization core 321 along the return groove
106 to be atomized again. Specifically, two return grooves 106 with the same diameter
are defined on the inner wall of the liquid absorbing structure 101. The return grooves
106 longitudinally extend from the next fin 104 of the top fin 104 of the liquid absorbing
structure 101 to the bottom fin. 104. The top fin 104 of the liquid absorbing structure
101 is configured to block the condensate in the return groove 106 from flowing to
the air outlet channel 121.
[0052] Further, as shown in FIG. 12, in order to make the refluxed cigarette liquid better
be sucked by the atomization core 321 and re-atomized, the length of the bottom fin
104 of the liquid absorbing structure 101 extending to the central axis of the absorbing
structure 101 is shorter than the length of an adjacent fin 104 extending to the central
axis.
[0053] In some embodiments, the air outlet channel 121 and the atomization assembly 30 are
arranged next to each other up and down. The liquid absorbing structure 101 and the
air outlet channel 121 are an integral structure. The liquid storage groove 105 is
defined on the inner wall surface of the air outlet channel 121. In the embodiments,
as shown in FIG. 12, the liquid absorbing structure 101 and the air outlet channel
121 are separate structures. The liquid absorbing structure 101 includes a cylindrical
body, which is arranged directly above the atomization assembly 30. The housing 10
includes a main body and an air outlet tube 12 longitudinally arranged in an internal
cavity of the main body. The air inlet channel 131, the atomization cavity 311, the
inner cavity of the liquid absorbing structure 101, and the air outlet tube 12 form
a complete air flow channel.
[0054] The liquid absorbing structure 101 is arranged directly above the atomization core
321 and is arranged next to the atomization core 321. The reason of this arrangement
is: when the electronic cigarette is heated, due to an oil film in the atomization
process, bubbles generated during the atomization process may easily bring out the
incompletely atomized cigarette liquid. When the smoke rises, the liquid absorbing
structure directly above the atomization core 321 sucks and stores the liquid droplets
carried in the smoke in the liquid storage groove, which greatly reduces the possibility
of leakage being inhaled.
[0055] The plurality of fins 104 are arranged on the inner wall surface of the cylindrical
body. As shown in FIG. 12, the cylindrical body includes a first part 102 and a second
part (not shown) that are detachably enclosed together. The inner wall surface of
the first part 102 is arranged with a plurality of first fins, and the inner wall
surface of the second part is arranged with a plurality of second fins. Specifically,
the liquid absorbing structure is cylindrical and may be formed by a combination of
two half-cylinders, and the fins are fan-ring shaped.
[0056] The atomization assembly 30 and the liquid absorbing structure 101 may also be arranged
in a same sleeve 107, and the liquid absorbing structure 101 is arranged next to the
atomization assembly 30. A position of the sleeve 107 corresponding to the atomization
assembly 30 defines at least one liquid inlet 110, which is configured to allow the
cigarette liquid in the liquid storage cavity 111 to enter the atomization core 321.
[0057] In addition, in order to fix the atomization assembly 30 and the liquid absorbing
structure 101 and make the installation more convenient, the outer side wall of the
liquid absorbing structure 101 and the inner side wall of the sleeve 107 are closely
arranged. In some embodiments, the liquid absorbing structure 101 and the sleeve 107
may be an integral structure.
[0058] In order to seal a connection between the sleeve 107 and the air outlet channel 121,
the sleeve 107 corresponding to the top of the liquid absorbing structure 101 is arranged
with a sealing member 108 that is sealed and connected to the air outlet channel 121.
The seal member may be a silicone sleeve or a rubber sleeve. It can be understood
that in other embodiments, the sealing member 108 is not limited to a silicone sleeve
or a rubber sleeve.
[0059] The present disclosure also provides an electronic atomization device, as shown in
FIGS. 9-12, which includes: a base 20; a housing 10 sleeved on the base 20, and sealed
and connected to the base 20 to define a liquid storage cavity 111; an electrode 90
arranged on a bottom of the base 20; a liquid injection assembly 109 arranged on and
penetrating the base 20 for filling the liquid storage cavity 111; an atomizer body
arranged on the base 20; an air flow channel running through the entire atomizer;
and a liquid absorbing structure 101. Among them, the atomizer body includes an atomization
assembly 30, and the air flow channel includes an air inlet channel 131, an atomization
cavity 311, and an air outlet channel 121. The liquid absorbing structure 101 is arranged
in the air outlet channel 121, and the liquid absorbing structure 101 defines a plurality
of liquid storage grooves 105 in a circumferential direction. The liquid storage groove
105 sucks a condensate in the air outlet channel 121 and/or an incomplete atomized
cigarette liquid carried out during an inhaling process by capillary forces. In the
embodiments, the material of the liquid absorbing structure 101 is one or more of
PETG, PCTG, and PC. The electronic atomization device may be a disposable atomization
device with the base, housing, and atomizer body in an integrated structure, and may
also be an atomization device with the base, housing, and atomizer body in a separate
structure.
[0060] Specifically, the liquid absorbing structure 101 includes a plurality of fins 104.
The fins 104 are arranged at intervals in parallel along a longitudinal direction,
and a liquid storage groove 105 is defined between every two adjacent fins 104. The
width of the liquid storage groove 105 is small enough to generate a capillary force
on the condensate, such that in the smoke generated during the inhaling process, the
liquid droplets brought out by the fin 104 structure will be trapped in the liquid
storage groove 105, and a liquid film is formed in the liquid storage groove 105.
In this way, the liquid droplets may be stored in the liquid storage groove 105 to
prevent the leakage of liquid from being inhaled.
[0061] The atomization assembly 30 includes a cylindrical atomization core 321, a liquid
guiding cotton 323 surrounding the atomization core 321, and a heating element 322
wound on the atomization core 321. A conductive connection part of the heating element
322 penetrates the base 20 and is connected to the electrode 90. In some embodiments,
the heating element 322 may be a heating wire. When in use, the atomization core 321
sucks the cigarette liquid in the liquid storage cavity 111, and the heating element
322 is energized to generate heat, such that the cigarette liquid in the atomization
core 321 is atomized. The user inhales through an inhaling port of a top cover of
the atomizer. Air enters the atomization core 321 from the air inlet channel 131 under
the inhaling action, is mixed with the atomized cigarette liquid in the atomization
core 321, and is discharged from the inhaling port of the top cover of the atomizer
after passing through the air outlet channel 121.
[0062] In the embodiments, the liquid absorbing structure 101 includes a plurality of fins
104. The fins 104 are arranged in parallel or non-parallel at intervals along the
longitudinal direction, and a liquid storage groove 105 is defined between every two
adjacent fins 104. The width of the liquid storage groove 105 is small enough to generate
a capillary force on the condensate, such that in the smoke generated during the inhaling
process, the liquid droplets brought out by passing through the fin 104 structure
will be trapped in the liquid storage groove 105, and a liquid film is formed in the
liquid storage groove 105. In this way, the liquid droplets may be stored in the liquid
storage groove 105 to prevent the leakage of liquid from being inhaled. The thickness
of the fin 104 and the width of the liquid storage groove 105 are 0.1-0.5 mm, and
in some embodiments 0.15-0.3 mm.
[0063] In order to prevent that too much cigarette liquid accumulated in the liquid storage
groove 105 in the liquid absorbing structure 101 will be taken out along with the
inhaling, in the embodiments, the liquid absorbing structure 101 includes: at least
one return groove 106 extending in the longitudinal direction. At least one return
groove 106 longitudinally intersects with at least part of the liquid storage groove
105. When the liquid storage groove 105 accumulates too much cigarette liquid, the
cigarette liquid may flow back to the atomization core 321 along the return groove
106 to be atomized again. Specifically, two return grooves 106 with the same diameter
are defined on the inner wall of the liquid absorbing structure 101. The return grooves
106 longitudinally extend from the next fin 104 of the top fin 104 of the liquid absorbing
structure 101 to the bottom fin. 104. The top fin 104 of the liquid absorbing structure
101 is configured to block the condensate in the return groove 106 from flowing to
the air outlet channel 121.
[0064] Further, as shown in FIG. 12, in order to make the refluxed cigarette liquid better
be sucked by the atomization core 321 and re-atomized, the length of the bottom fin
104 of the liquid absorbing structure 101 extending to the central axis of the liquid
absorbing structure 101 is shorter than the length of an adjacent fin 104 extending
to the central axis.
[0065] In some embodiments, the air outlet channel 121 and the atomization assembly 30 are
arranged next to each other up and down. The liquid absorbing structure 101 and the
air outlet channel 121 are an integral structure. The liquid storage groove 105 is
defined on the inner wall surface of the air outlet channel 121. In the embodiments,
as shown in FIG. 12, the liquid absorbing structure 101 and the air outlet channel
121 are separate structures. The liquid absorbing structure 101 includes a cylindrical
body, which is arranged directly above the atomization assembly 30. The housing 10
includes a main body and an air outlet tube 12 longitudinally arranged in an internal
cavity of the main body. The air inlet channel 131, the atomization cavity 311, the
inner cavity of the liquid absorbing structure 101, and the air outlet tube 12 form
a complete air flow channel.
[0066] The liquid absorbing structure 101 is arranged directly above the atomization core
321 and is arranged next to the atomization core 321. The reason of this arrangement
is: when the electronic cigarette is heated, due to an oil film in the atomization
process, bubbles generated during the atomization process may easily bring out the
incompletely atomized cigarette liquid. When the smoke rises, the liquid absorbing
structure directly above the atomization core 321 sucks and stores the liquid droplets
carried in the smoke in the liquid storage groove, which greatly reduces the possibility
of leakage being inhaled.
[0067] The plurality of fins 104 are arranged on the inner wall surface of the cylindrical
body. As shown in FIG. 12, the cylindrical body includes a first part 102 and a second
part (not shown) that are detachably enclosed together. The inner wall surface of
the first part 102 is arranged with a plurality of first fins, and the inner wall
surface of the second part is arranged with a plurality of second fins. Specifically,
the liquid absorbing structure is cylindrical and may be formed by a combination of
two half-cylinders, and the fins are fan-ring shaped.
[0068] The atomization assembly 30 and the liquid absorbing structure 101 may also be arranged
in a same sleeve 107, and the liquid absorbing structure 101 is arranged next to the
atomization assembly 30. The sleeve 107 corresponding to the atomization assembly
30 defines at least one liquid inlet 110, which is configured to allow the cigarette
liquid in the liquid storage cavity 111 to enter the atomization core 321.
[0069] In addition, in order to fix the atomization assembly 30 and the liquid absorbing
structure 101 and make the installation more convenient, the outer side wall of the
liquid absorbing structure 101 and the inner side wall of the sleeve 107 are closely
arranged. In some embodiments, the liquid absorbing structure 101 and the sleeve 107
may be an integral structure.
[0070] In order to seal a connection between the sleeve 107 and the air outlet channel 121,
a position of the sleeve 107 corresponding to the top of the liquid absorbing structure
101 is arranged with a sealing member 108 that is sealed and connected to the air
outlet channel 121. The seal member may be a silicone sleeve or a rubber sleeve. It
can be understood that in other embodiments, the sealing member 108 is not limited
to a silicone sleeve or a rubber sleeve.
[0071] By implementing the second embodiment, the following beneficial effects may be achieved:
[0072] In the present disclosure, the liquid absorbing structure is arranged in the air
outlet channel, and the plurality of liquid storage grooves are defined in the circumferential
direction of the liquid absorbing structure. The liquid storage groove sucks the condensate
in the air outlet channel by capillary force, such that the condensate generated in
the inhaling process and/or the cigarette liquid that is not completely atomized stays
in the liquid storage groove and is stored in the liquid storage groove with a liquid
film formed in the liquid storage groove, thereby preventing the user from inhaling
the leaking liquid during the inhaling process and improving the user's experience.
[0073] In addition, the liquid absorbing structure includes the plurality of fins, the fins
are arranged in parallel and spaced along the longitudinal direction, and the liquid
storage groove is defined between each two adjacent fins. In the smoke generated during
the inhaling process, the liquid droplets brought out by passing through the fin will
be trapped in the liquid storage groove.
[0074] In order to further prevent that too much cigarette liquid accumulated in the liquid
storage groove in the liquid absorbing structure will be carried out with suction,
the liquid absorbing structure of the present disclosure includes at least one return
groove extending in the longitudinal direction, and at least one return groove longitudinally
intersects with at least part of the liquid storage groove. When the liquid storage
groove accumulates too much cigarette liquid, the cigarette liquid may flow back to
the atomization core along the return groove to be atomized again.
[0075] In order to better suck and re-atomize the refluxed cigarette liquid, the length
of the bottom fin of the liquid absorbing structure extending to the central axis
of the liquid absorbing structure is shorter than the length of the adjacent fin extending
to the central axis.
[0076] In addition, when the electronic cigarette is heated, due to an oil film in the atomization
process, bubbles generated during the atomization process may easily bring out the
incompletely atomized cigarette liquid. When the smoke rises, the liquid absorbing
structure directly above the atomization core sucks and stores the liquid droplets
carried in the smoke in the liquid storage groove, which greatly reduces the possibility
of leakage being inhaled.
[0077] FIGS. 9, 10, 11, 13-17 show a third embodiment of the atomizer of the present disclosure.
As shown in FIGS. 9, 10 and 11, the present disclosure provides an atomizer, a base
20; a housing 10 sleeved on the base 20, and sealed and connected to the base 20 to
define a liquid storage cavity 111; an electrode 90 arranged on a bottom of the base
20; a liquid injection assembly 109 arranged on and penetrating the base 20 for filling
the liquid storage cavity 111; an atomizer body arranged on the base 20; an air flow
channel running through the entire atomizer; and a first liquid absorbing structure
and a second liquid absorbing structure. Among them, the base includes a liquid storage
structure, and the liquid storage structure refers to the first embodiment, which
will not be repeated here. The atomizer body includes an atomization assembly 30,
and the air flow channel includes an air inlet channel 131, an atomization cavity
311, and an air outlet channel 121. The first liquid absorbing structure and the second
liquid absorbing structure are connected to the air outlet channel 121 in a liquid
conducting manner. The first liquid absorbing structure and the second liquid absorbing
structure suck the condensate formed on the air outlet channel 121 by capillary force.
The second liquid absorbing structure is arranged between the atomization assembly
30 and the first liquid absorbing structure, and the capillary force of the second
liquid absorbing structure is greater than that of the first liquid absorbing structure.
The second liquid absorbing structure defines a liquid storage groove 105 that sucks
and stores condensate by capillary force. The condensate in the first liquid absorbing
structure reaches the second liquid absorbing structure under the capillary force
of the liquid storage groove 105 to be sucked and stored.
[0078] In the embodiments, the second liquid absorbing structure has an inner wall, the
inner wall is recessed to define the liquid storage groove 105, and the inner wall
of the second liquid absorbing structure encloses a part of the air outlet channel
121. The first liquid absorbing structure is a liquid absorbing groove 122 extending
along the longitudinal direction of the inner wall of the air outlet channel 121,
and an end of the liquid absorbing groove 122 is butted with the liquid storage groove
105.
[0079] In the embodiments, the air outlet channel 121 includes a detachable first airway
wall and a second airway wall. The first liquid absorbing structure is formed on the
first airway wall, and the second airway wall is the inner wall of the first liquid
absorbing structure. As shown in FIG. 11, the housing 10 includes a main body and
an air outlet tube 12 longitudinally arranged in the internal cavity of the main body.
The second liquid absorbing structure is arranged below the air outlet tube 12, and
the first airway wall is the air outlet tube 12. The second airway wall is the inner
wall of the first liquid absorbing structure, and a complete air outlet channel 121
is formed by the air outlet tube 12 and the inner cavity of the second liquid absorbing
structure.
[0080] In other embodiments, the second liquid absorbing structure may be formed on an integrally
formed single element. For example, the air outlet tube 12 and the atomization assembly
30 are arranged next to each other up and down, and the second liquid absorbing structure
and the air outlet tube 12 may be an integrated structure. The liquid storage groove
105 is defined on the inner wall surface of the air outlet tube 12. While in the embodiments,
the second liquid absorbing structure and the air outlet tube 12 are separate structures,
and the second liquid absorbing structure includes a cylindrical body, which is arranged
directly above the atomization assembly 30. The air inlet channel 131, the atomization
cavity 311, the inner cavity of the second liquid absorbing structure, and the air
outlet tube 12 form a complete air flow channel.
[0081] As shown in FIGS. 13 and 14, the air outlet tube 12 includes a first end 1211 close
to the atomization assembly 30 and a second end 1212 far away from the atomization
assembly 30. The liquid absorbing groove 122 extends longitudinally from the first
end 1211 of the air outlet tube 12 toward the second end 1212 of the air outlet tube
12. The number of liquid absorbing grooves 122 is more than one, and the liquid absorbing
grooves 122 are evenly distributed along the peripheral wall of the air outlet channel
121. The liquid absorbing grooves 122 are parallel to the central axis of the air
outlet channel 121. The first liquid absorbing structure is detachably connected or
fixedly connected to the inner side wall of the air outlet tube 12. In the embodiments,
the first liquid absorbing structure is fixedly connected to the inner side wall of
the air outlet tube 12, that is, the first liquid absorbing structure and the air
outlet tube 12 are an integral structure. At least one longitudinally extending liquid
absorbing groove 122 is defined on the inner side wall of the air outlet tube 12.
The liquid absorbing groove 122 is not limited to being arranged in the longitudinal
direction, and it can be arranged spirally, or inclinedly, or the inner side wall
surface is arranged with a rough surface texture to increase the wettability of the
surface to the condensate. In other embodiments, the leakage guide is detachably connected
to the inner side wall of the air outlet tube 12 by pasting, snapping, or the like.
[0082] As shown in FIG. 11, the atomization assembly 30 includes a cylindrical atomization
core 321, a liquid guiding cotton 323 surrounding the atomization core 321, and a
heating element 322 wound around the atomization core 321. A conductive connecting
part of the heating element 322 penetrates the base 20 and is connected to the electrode
90. In some embodiments, the heating element 322 may be a heating wire. When in use,
the liquid guiding cotton 323 sucks the cigarette liquid in the liquid storage cavity
111, and the heating element 322 is energized to generate heat, such that the cigarette
liquid in the atomization core 321 is atomized. The user inhales through an inhaling
port of a top cover of the atomizer. Air enters the atomization core 321 from the
air inlet channel under the inhaling action, is mixed with the atomized cigarette
liquid in the atomization core 321, and is discharged from the inhaling port of the
top cover of the atomizer after passing through the air outlet channel 121.
[0083] When the atomized gas reaches the air outlet through the air outlet channel 121,
airflow around the air outlet channel 121 meets the inner side wall of the air outlet
tube 12 to condense to form smoke oil condensate. At this time, the liquid absorbing
groove 122 sucks the condensate by capillary action. Since the capillary force of
the liquid storage groove 105 is greater than the capillary force of the liquid absorbing
groove 122, the condensate in the liquid absorbing groove 122 reaches the second liquid
absorbing structure under the capillary force of the liquid storage groove 105 to
be sucked and stored.
[0084] In order to make the condensate sucked into the liquid absorbing groove 122 better
flow back to the second liquid absorbing structure under the capillary force of the
liquid storage groove 105, and be sucked and stored by the second liquid absorbing
structure, the depth of the liquid absorbing groove 122 gradually increases along
a direction toward the liquid storage groove 105, that is, gradually increasing from
the second end 1212 to the first end 1211. In some embodiments, the depth of the liquid
absorbing groove 122 is greater than or equal to 0.1 mm.
[0085] It may also be arranged by setting the width of the liquid absorbing groove 122 to
gradually increase along the direction toward the liquid storage groove 105, that
is, gradually increasing from the second end 1212 to the first end 1211. And the width
of the liquid absorbing groove 122 to gradually increase along a direction from a
bottom to an opening. In some embodiments, the width of the liquid absorbing groove
122 is 0.05-1 mm.
[0086] Based on the above embodiments of the first liquid absorbing structure, the bottom
of the second liquid absorbing structure abuts against the liquid guiding cotton 323
of the atomization assembly 30, and the bottom of the second liquid absorbing structure
is arranged with a reflux structure to connect the liquid storage groove 105 and the
liquid guiding cotton 323 in a liquid conducting manner, such that the condensate
in the liquid storage groove 105 is returned to the liquid guiding cotton 323 to be
sucked and reused. The reflux structure may be a return groove or a liquid outlet
or a stepped structure.
[0087] As shown in FIG. 15, in some embodiments, the liquid storage groove 105 is a horizontal
liquid storage groove. Specifically, a plurality of first fins 104 are arranged on
the inner wall of the second liquid absorbing structure, and the first fins 104 are
arranged in parallel and spaced apart along the longitudinal direction. Each two adjacently
arranged first fins 104 define a transverse liquid storage groove therebetween. The
width of the liquid storage groove 105 is small enough to generate capillary force
on the condensate, such that in the smoke generated during the inhaling process, the
liquid droplets brought out by passing through the fin 104 structure will be trapped
in the liquid storage groove 105, and a liquid film is formed in the liquid storage
groove 105. In this way, the liquid droplets may be stored in the liquid storage groove
105 to prevent the leakage of liquid from being inhaled.
[0088] In order to prevent excessive cigarette liquid accumulated in the liquid storage
groove 105 in the second liquid absorbing structure, which will be carried out with
inhaling, and to achieve reuse of the condensate, in the embodiments, the second absorbing
structure includes: at least one return groove 106 extending in the longitudinal direction.
At least one return groove 106 longitudinally intersects with at least part of the
liquid storage groove 105. When the liquid storage groove 105 accumulates too much
cigarette liquid, the cigarette liquid may flow back to the atomization core 321 along
the return groove 106 to be atomized again. Specifically, two return grooves 106 with
the same diameter are defined on the inner wall of the liquid absorbing structure
101. The return grooves 106 longitudinally extend from the next fin 104 of the top
fin 104 of the liquid absorbing structure 101 to the bottom fin. 104. The top fin
104 of the liquid absorbing structure 101 is configured to block the condensate in
the return groove 106 from flowing to the air outlet channel 121.
[0089] In order to make the refluxed cigarette liquid better be sucked by the atomization
core 321 and re-atomized, the length of the bottom fin 104 of the liquid absorbing
structure 101 extending to the central axis of the absorbing structure 101 is shorter
than the length of an adjacent fin 104 extending to the central axis.
[0090] Since the condensate in the liquid absorbing groove 122 will reach the second liquid
absorbing structure under the capillary force of the liquid storage groove 105 to
be sucked and stored, the first fin 104 on the top of the second liquid absorbing
structure defines a first liquid guiding port 117 facing the liquid absorbing groove
122. The first liquid guiding port 117 is configured to divert the condensate in the
liquid absorbing groove 122 to the liquid storage groove 105, so as to be better sucked
and stored by the second liquid absorbing structure. Specifically, in the embodiments,
the second liquid absorbing structure is cylindrical, the top first fin 104 is circular,
and the other fins are fan ring shaped. The first liquid guiding port 117 is a notch
defined on the inner circular edge of the top first fin 104.
[0091] The plurality of first fins 104 are arranged on the inner wall surface of the cylindrical
body. As shown in FIG. 15, the cylindrical body includes a first part 102 and a second
part (not shown) that are detachably enclosed together. The inner wall surfaces of
the first part 102 and the second part are arranged with the plurality of first fins.
Specifically, the liquid absorbing structure is cylindrical and may be formed by a
combination of two half-cylinders. The top first fin 104 has a semicircular ring shape,
and the other fins have a fan ring shape.
[0092] As shown in FIGS. 16 and 17, in some embodiments, the liquid storage groove 105 is
a longitudinal liquid storage groove. Specifically, the second liquid absorbing structure
is a hollow structure with a top wall 113 on the top, a plurality of liquid storage
plates 114 are arranged from the top wall 113 longitudinally to the bottom, with the
liquid storage plates 114 spaced apart. A liquid storage groove 105 is defined between
each adjacent two liquid storage plates 114.
[0093] In order to achieve better diversion and liquid suction, in the embodiments, the
second liquid absorbing structure further includes at least one liquid guide groove
115 for diverting condensate connected to a part of the liquid storage groove 105.
The liquid guide groove 115 transversely intersects with the middle of at least some
of the liquid storage plates 114. In some embodiments, the liquid guide groove 115
and the liquid storage groove 114 are not limited to be parallel or perpendicular,
as long as the cross flow can be achieved.
[0094] In order to achieve diversion at the bottom of the second liquid absorbing structure,
the second liquid absorbing structure further includes at least one first stepped
platform 116 for diverting condensate. The first stepped platform 116 transversely
intersects with the bottom of some of the liquid storage plates 114. In the embodiments,
the first stepped platform 116 transversely intersects with the bottom of all the
liquid storage plates 114.
[0095] In order to allow the divided condensate to better flow back to the atomization core
and be re-atomized, the at least one first stepped platform 116 is arranged with a
second stepped platform 125. In the embodiments, second stepped platforms 125 are
arranged on two first stepped platforms 116. The first stepped platforms 116, the
second stepped platforms 125 and the liquid storage groove 105 form a stepped structure.
[0096] Similarly, since the condensate in the liquid absorbing groove 122 will reach the
second liquid absorbing structure under the capillary force of the liquid storage
groove 105 to be sucked and stored, the top wall 113 of the second liquid absorbing
structure defines a second liquid guiding port 118 facing the liquid absorbing groove
122. Specifically, in the embodiments, the second liquid absorbing structure is cylindrical,
the top wall 113 is circular, and the second liquid guiding port 118 is a notch defined
on the inner circular edge of the top wall 113.
[0097] A plurality of liquid storage plates 114 are arranged on the inner wall of the cylindrical
body. The cylindrical body includes a first part and a second part that are detachably
enclosed together. The inner wall surfaces of the first part and the second part are
arranged with a plurality of liquid storage plates 114. Specifically, the second liquid
absorbing structure is cylindrical, and may be formed by combining two semi-cylindricals.
[0098] In some embodiments, the liquid storage groove 105 is a threaded liquid storage groove,
and includes: a second fin 120 arranged in a spiral on the inner wall to form the
liquid storage groove 105 with a threaded structure.
[0099] In order to allow the condensate in the liquid storage groove 105 to flow back to
the atomization core and be re-atomized, the second liquid absorbing structure includes
at least one liquid outlet, which longitudinally cuts the second fin 120 at the bottom
part.
[0100] A plurality of second fins 120 are arranged on the inner wall of the cylindrical
body. The cylindrical body includes a first part and a second part that are detachably
enclosed together. The inner wall surfaces of the first part and the second part are
arranged with the plurality of second fins 120. Specifically, the second liquid absorbing
structure is cylindrical, and may be formed by combining two semi-cylindricals.
[0101] In the above embodiments, the reason why the second liquid absorbing structure is
arranged directly above the atomization core 321 and adjacent to the atomization core
321 is that: when the electronic cigarette is heated and atomized, the smoke passes
through the air outlet channel and condensate is easily formed on the airway wall.
The second liquid absorbing structure of the present disclosure arranged directly
above the atomization assembly can suck and store the liquid droplets carried in the
smoke in the liquid storage groove, which greatly reduces the possibility of inhaling
leakage.
[0102] In some embodiments, the depth of the liquid storage groove 105 is greater than or
equal to 0.1 mm, and the width of the liquid storage groove 105 is 0.05-1 mm. The
material of the second liquid absorbing structure may also be one or more of PETG,
PCTG and PC.
[0103] Moreover, in the embodiments, as shown in FIG. 11, the atomization assembly 30 and
the second liquid absorbing structure are also arranged in a same sleeve 107, and
the second liquid absorbing structure is arranged next to the atomization assembly
30. A position of the sleeve 107 corresponding to the atomization assembly 30 defines
at least one liquid inlet 110, which is configured to allow the cigarette liquid in
the liquid storage cavity 111 to be sucked by the liquid guiding cotton 323.
[0104] In order to fix the atomization assembly 30 and the second liquid absorbing structure
and make the installation more convenient, the outer side wall of the second liquid
absorbing structure and the inner side wall of the sleeve 107 are closely arranged.
In some embodiments, the second liquid absorbing structure and the sleeve 107 may
be an integral structure.
[0105] In order to seal the connection between the sleeve 107 and the air outlet channel
121, a position of the sleeve 107 corresponding to the top of the second liquid absorbing
structure is arranged with a sealing member 108 that is sealed and connected to the
air outlet channel 121. The seal member may be a silicone sleeve or a rubber sleeve.
It can be understood that in other embodiments, the sealing member 108 is not limited
to a silicone sleeve or a rubber sleeve.
[0106] The present disclosure also proposes an electronic atomization device, as shown in
FIGS. 9, 10 and 11, including a base 20, a housing 10 sleeved on the base 20, and
sealed and connected to the base 20 to define a liquid storage cavity 111; an electrode
90 arranged on a bottom 20 of the base 20; a liquid injection assembly 109 arranged
on and penetrating the base 20 for filling the liquid storage cavity 111; an atomizer
body arranged on the base 20; an air flow channel running through the entire atomizer;
and a first liquid absorbing structure and a second liquid absorbing structure. Among
them, the atomizer body includes an atomization assembly 30, and the air flow channel
includes an air inlet channel 131, an atomization cavity 311, and an air outlet channel
121. The first liquid absorbing structure and the second liquid absorbing structure
are connected to the air outlet channel 121 in a liquid conducting manner. The first
liquid absorbing structure and the second liquid absorbing structure suck the condensate
formed on the air outlet channel 121 by capillary force. The second liquid absorbing
structure is arranged between the atomization assembly 30 and the first liquid absorbing
structure, and the capillary force of the second liquid absorbing structure is greater
than that of the first liquid absorbing structure. The second liquid absorbing structure
defines a liquid storage groove 105 that sucks and stores condensate by capillary
force. The condensate in the first liquid absorbing structure reaches the second liquid
absorbing structure under the capillary force of the liquid storage groove 105 to
be sucked and stored. In the embodiment, the electronic atomization device is a disposable
atomization device with the base, the housing, and the atomizer body in an integrated
structure, or a disposable atomization device with the base, the housing, and the
atomizer body in a separated structure.
[0107] In the embodiments, the second liquid absorbing structure has an inner wall, the
inner wall is recessed to define the liquid storage groove 105, and the inner wall
of the second liquid absorbing structure encloses a part of the air outlet channel
121. The first liquid absorbing structure is a liquid absorbing groove 122 extending
along the longitudinal direction of the inner wall of the air outlet channel 121,
and an end of the liquid absorbing groove 122 is butted with the liquid storage groove
105.
[0108] In the embodiments, the air outlet channel 121 includes a detachable first airway
wall and a second airway wall. The first liquid absorbing structure is formed on the
first airway wall, and the second airway wall is the inner wall of the first liquid
absorbing structure. As shown in FIG. 11, the housing 10 includes a main body and
an air outlet tube 12 longitudinally arranged in the internal cavity of the main body.
The second liquid absorbing structure is arranged below the air outlet tube 12, and
the first airway wall is the air outlet tube 12. The second airway wall is the inner
wall of the first liquid absorbing structure, and a complete air outlet channel 121
is formed by the air outlet tube 12 and the inner cavity of the second liquid absorbing
structure.
[0109] In other embodiments, the second liquid absorbing structure may be formed on an integrally
formed single element. For example, the air outlet tube 12 and the atomization assembly
30 are arranged next to each other up and down, and the second liquid absorbing structure
and the air outlet tube 12 may be an integrated structure. The liquid storage groove
105 is defined on the inner wall surface of the air outlet tube 12. While in the embodiments,
the second liquid absorbing structure and the air outlet tube 12 are separate structures,
and the second liquid absorbing structure includes a cylindrical body, which is arranged
directly above the atomization assembly 30. The air inlet channel 131, the atomization
cavity 311, the inner cavity of the second liquid absorbing structure, and the air
outlet tube 12 form a complete air flow channel.
[0110] As shown in FIGS. 13 and 14, the air outlet tube 12 includes a first end 1211 close
to the atomization assembly 30 and a second end 1212 far away from the atomization
assembly 30. The liquid absorbing groove 122 extends longitudinally from the first
end 1211 of the air outlet tube 12 toward the second end 1212 of the air outlet tube
12. The number of liquid absorbing grooves 122 is more than one, and the liquid absorbing
grooves 122 are evenly distributed along the peripheral wall of the air outlet channel
121. The liquid absorbing grooves 122 are parallel to the central axis of the air
outlet channel 121. The first liquid absorbing structure is detachably connected or
fixedly connected to the inner side wall of the air outlet tube 12. In the embodiments,
the first liquid absorbing structure is fixedly connected to the inner side wall of
the air outlet tube 12, that is, the first liquid absorbing structure and the air
outlet tube 12 are an integral structure. At least one longitudinally extending liquid
absorbing groove 122 is defined on the inner side wall of the air outlet tube 12.
The liquid absorbing groove 122 is not limited to being arranged in the longitudinal
direction, and it can be arranged spirally, or inclinedly, or the inner side wall
surface is arranged with a rough surface texture to increase the wettability of the
surface to the condensate. In other embodiments, the leakage guide is detachably connected
to the inner side wall of the air outlet tube 12 by pasting, snapping, or the like.
[0111] As shown in FIG. 11, the atomization assembly 30 includes a cylindrical atomization
core 321, a liquid guiding cotton 323 surrounding the atomization core 321, and a
heating element 322 wound around the atomization core 321. A conductive connecting
part of the heating element 322 penetrates the base 20 and is connected to the electrode
90. In some embodiments, the heating element 322 may be a heating wire. When in use,
the liquid guiding cotton 323 sucks the cigarette liquid in the liquid storage cavity
111, and the heating element 322 is energized to generate heat, such that the cigarette
liquid in the atomization core 321 is atomized. The user inhales through an inhaling
port of a top cover of the atomizer. Air enters the atomization core 321 from the
air inlet channel under the inhaling action, is mixed with the atomized cigarette
liquid in the atomization core 321, and is discharged from the inhaling port of the
top cover of the atomizer after passing through the air outlet channel 121.
[0112] When the atomized gas reaches the air outlet through the air outlet channel 121,
airflow around the air outlet channel 121 meets the inner side wall of the air outlet
tube 12 to condense to form smoke oil condensate. At this time, the liquid absorbing
groove 122 sucks the condensate by capillary action. Since the capillary force of
the liquid storage groove 105 is greater than the capillary force of the liquid absorbing
groove 122, the condensate in the liquid absorbing groove 122 reaches the second liquid
absorbing structure under the capillary force of the liquid storage groove 105 to
be sucked and stored.
[0113] In order to make the condensate sucked into the liquid absorbing groove 122 better
flow back to the second liquid absorbing structure under the capillary force of the
liquid storage groove 105, and be sucked and stored by the second liquid absorbing
structure, the depth of the liquid absorbing groove 122 gradually increases along
a direction toward the liquid storage groove 105, that is, gradually increasing from
the second end 1212 to the first end 1211. In some embodiments, the depth of the liquid
absorbing groove 122 is greater than or equal to 0.1 mm.
[0114] It may also be arranged by setting the width of the liquid absorbing groove 122 to
gradually increase along the direction toward the liquid storage groove 105, that
is, gradually increasing from the second end 1212 to the first end 1211. And the width
of the liquid absorbing groove 122 to gradually increase along a direction from a
bottom to an opening. In some embodiments, the width of the liquid absorbing groove
122 is 0.05-1 mm.
[0115] Based on the above embodiments of the first liquid absorbing structure, the bottom
of the second liquid absorbing structure abuts against the liquid guiding cotton 323
of the atomization assembly 30, and the bottom of the second liquid absorbing structure
is arranged with a reflux structure to connect the liquid storage groove 105 and the
liquid guiding cotton 323 in a liquid conducting manner, such that the condensate
in the liquid storage groove 105 is returned to the liquid guiding cotton 323 to be
sucked and reused. The reflux structure may be a return groove or a liquid outlet
or a stepped structure.
[0116] As shown in FIG. 15, in some embodiments, the liquid storage groove 105 is a horizontal
liquid storage groove. Specifically, a plurality of first fins 104 are arranged on
the inner wall of the second liquid absorbing structure, and the first fins 104 are
arranged in parallel and spaced apart along the longitudinal direction. Each two adjacently
arranged first fins 104 define a transverse liquid storage groove therebetween. The
width of the liquid storage groove 105 is small enough to generate capillary force
on the condensate, such that in the smoke generated during the inhaling process, the
liquid droplets brought out by passing through the fin 104 structure will be trapped
in the liquid storage groove 105, and a liquid film is formed in the liquid storage
groove 105. In this way, the liquid droplets may be stored in the liquid storage groove
105 to prevent the leakage of liquid from being inhaled.
[0117] In order to prevent excessive cigarette liquid accumulated in the liquid storage
groove 105 in the second liquid absorbing structure, which will be carried out with
inhaling, and to achieve reuse of the condensate, in the embodiments, the second absorbing
structure includes: at least one return groove 106 extending in the longitudinal direction.
At least one return groove 106 longitudinally intersects with at least part of the
liquid storage groove 105. When the liquid storage groove 105 accumulates too much
cigarette liquid, the cigarette liquid may flow back to the atomization core 321 along
the return groove 106 to be atomized again. Specifically, two return grooves 106 with
the same diameter are defined on the inner wall of the liquid absorbing structure
101. The return grooves 106 longitudinally extend from the next fin 104 of the top
fin 104 of the liquid absorbing structure 101 to the bottom fin. 104. The top fin
104 of the liquid absorbing structure 101 is configured to block the condensate in
the return groove 106 from flowing to the air outlet channel 121.
[0118] In order to make the refluxed cigarette liquid better be sucked by the atomization
core 321 and re-atomized, the length of the bottom fin 104 of the liquid absorbing
structure 101 extending to the central axis of the absorbing structure 101 is shorter
than the length of an adjacent fin 104 extending to the central axis.
[0119] Since the condensate in the liquid absorbing groove 122 will reach the second liquid
absorbing structure under the capillary force of the liquid storage groove 105 to
be sucked and stored, the first fin 104 on the top of the second liquid absorbing
structure defines a first liquid guiding port 117 facing the liquid absorbing groove
122. The first liquid guiding port 117 is configured to divert the condensate in the
liquid absorbing groove 122 to the liquid storage groove 105, so as to be better sucked
and stored by the second liquid absorbing structure. Specifically, in the embodiments,
the second liquid absorbing structure is cylindrical, the top first fin 104 is circular,
and the other fins are fan ring shaped. The first liquid guiding port 117 is a notch
defined on the inner circular edge of the top first fin 104.
[0120] The plurality of first fins 104 are arranged on the inner wall surface of the cylindrical
body. As shown in FIG. 15, the cylindrical body includes a first part 102 and a second
part (not shown) that are detachably enclosed together. The inner wall surfaces of
the first part 102 and the second part are arranged with the plurality of first fins.
Specifically, the liquid absorbing structure is cylindrical and may be formed by a
combination of two half-cylinders. The top first fin 104 has a semicircular ring shape,
and the other fins have a fan ring shape.
[0121] As shown in FIGS. 16 and 17, in some embodiments, the liquid storage groove 105 is
a longitudinal liquid storage groove. Specifically, the second liquid absorbing structure
is a hollow structure with a top wall 113 on the top, a plurality of liquid storage
plates 114 are arranged from the top wall 113 longitudinally to the bottom, with the
liquid storage plates 114 spaced apart. A liquid storage groove 105 is defined between
each adjacent two liquid storage plates 114.
[0122] In order to achieve better diversion and liquid suction, in the embodiments, the
second liquid absorbing structure further includes at least one liquid guide groove
115 for diverting condensate connected to a part of the liquid storage groove 105.
The liquid guide groove 115 transversely intersects with the middle of at least some
of the liquid storage plates 114. In some embodiments, the liquid guide groove 115
and the liquid storage plate 114 are not limited to be parallel or perpendicular,
as long as the cross flow can be achieved.
[0123] In order to achieve diversion at the bottom of the second liquid absorbing structure,
the second liquid absorbing structure further includes at least one first stepped
platform 116 for diverting condensate. The first stepped platform 116 transversely
intersects with the bottom of some of the liquid storage plates 114. In the embodiments,
the first stepped platform 116 transversely intersects with the bottom of all the
liquid storage plates 114.
[0124] In order to allow the divided condensate to better flow back to the atomization core
and be re-atomized, the at least one first stepped platform 116 is arranged with a
second stepped platform 125. In the embodiments, second stepped platforms 125 are
arranged on two first stepped platforms 116. The first stepped platforms 116, the
second stepped platforms 125 and the liquid storage groove 105 form a stepped structure.
[0125] Similarly, since the condensate in the liquid absorbing groove 122 will reach the
second liquid absorbing structure under the capillary force of the liquid storage
groove 105 to be sucked and stored, the top wall 113 of the second liquid absorbing
structure defines a second liquid guiding port 118 facing the liquid absorbing groove
122. Specifically, in the embodiments, the second liquid absorbing structure is cylindrical,
the top wall 113 is circular, and the second liquid guiding port 118 is a notch defined
on the inner circular edge of the top wall 113.
[0126] A plurality of liquid storage plates 114 are arranged on the inner wall of the cylindrical
body. The cylindrical body includes a first part and a second part that are detachably
enclosed together. The inner wall surfaces of the first part and the second part are
arranged with a plurality of liquid storage plates 114. Specifically, the second liquid
absorbing structure is cylindrical, and may be formed by combining two semi-cylindricals.
[0127] In some embodiments, the liquid storage groove 105 is a threaded liquid storage groove,
and includes: a second fin 120 arranged in a spiral on the inner wall to form the
liquid storage groove 105 with a threaded structure.
[0128] In order to allow the condensate in the liquid storage groove 105 to flow back to
the atomization core and be re-atomized, the second liquid absorbing structure includes
at least one liquid outlet, which longitudinally cuts the second fin 120 at the bottom
part.
[0129] A plurality of second fins 120 are arranged on the inner wall of the cylindrical
body. The cylindrical body includes a first part and a second part that are detachably
enclosed together. The inner wall surfaces of the first part and the second part are
arranged with the plurality of second fins 120. Specifically, the second liquid absorbing
structure is cylindrical, and may be formed by combining two semi-cylindricals.
[0130] In the above embodiments, the reason why the second liquid absorbing structure is
arranged directly above the atomization core 321 and adjacent to the atomization core
321 is that: when the electronic cigarette is heated and atomized, the smoke passes
through the air outlet channel and condensate is easily formed on the airway wall.
The second liquid absorbing structure of the present disclosure arranged directly
above the atomization assembly can suck and store the liquid droplets carried in the
smoke in the liquid storage groove, which greatly reduces the possibility of inhaling
leakage.
[0131] In some embodiments, the depth of the liquid storage groove 105 is greater than or
equal to 0.1 mm, and the width of the liquid storage groove 105 is 0.05-1 mm. The
material of the second liquid absorbing structure may also be one or more of PETG,
PCTG and PC.
[0132] Moreover, in the embodiments, as shown in FIG. 11, the atomization assembly 30 and
the second liquid absorbing structure are also arranged in a same sleeve 107, and
the second liquid absorbing structure is arranged next to the atomization assembly
30. A position of the sleeve 107 corresponding to the atomization assembly 30 defines
at least one liquid inlet 110, which is configured to allow the cigarette liquid in
the liquid storage cavity 111 to be sucked by the liquid guiding cotton 323.
[0133] In order to fix the atomization assembly 30 and the second liquid absorbing structure
and make the installation more convenient, the outer side wall of the second liquid
absorbing structure and the inner side wall of the sleeve 107 are closely arranged.
In some embodiments, the second liquid absorbing structure and the sleeve 107 may
be an integral structure.
[0134] In order to seal the connection between the sleeve 107 and the air outlet channel
121, a position of the sleeve 107 corresponding to the top of the second liquid absorbing
structure is arranged with a sealing member 108 that is sealed and connected to the
air outlet channel 121. The seal member may be a silicone sleeve or a rubber sleeve.
It can be understood that in other embodiments, the sealing member 108 is not limited
to a silicone sleeve or a rubber sleeve.
[0135] By implementing the third embodiment, the following beneficial effects are achieved:
[0136] In the present disclosure, the first liquid absorbing structure and the second liquid
absorbing structure connected in a liquid conducting manner are arranged on the air
outlet channel. The first liquid absorbing structure and the second liquid absorbing
structure suck the condensate formed on the air outlet channel by capillary force.
The second liquid absorbing structure is arranged between the atomization assembly
and the first liquid absorbing structure, and the capillary force of the second liquid
absorbing structure is greater than that of the first liquid absorbing structure.
The second liquid absorbing structure defines a liquid storage groove that sucks and
stores condensate by capillary force. The condensate in the first liquid absorbing
structure reaches the second liquid absorbing structure under the capillary force
of the liquid storage groove to be sucked and stored, which makes smoke oil not fully
atomized in the inhaling process and condensate generated on the outlet channel to
be absorbed and stored, preventing users from inhaling leakage during the inhaling
process, and improving the user experience.
[0137] In addition, the bottom of the second liquid absorbing structure of the present disclosure
abuts against the liquid guiding cotton 323, and the bottom of the second liquid absorbing
structure is arranged with a backflow structure to allow the liquid storage groove
and the liquid guiding cotton 323 to communicate with each other. The condensate in
the liquid reservoir is recovered to the liquid guiding cotton 323 to be re-atomized
to improve the utilization rate of the cigarette oil.
[0138] When the electronic cigarette is heated and atomized, the smoke passes through the
air outlet channel and condensate is easily formed on the airway wall. The second
liquid absorbing structure of the present disclosure arranged directly above the atomization
assembly can suck and store the liquid droplets carried in the smoke in the liquid
storage groove, which greatly reduces the possibility of inhaling leakage.
[0139] It is to be understood that the above examples only present preferred embodiments
of the present disclosure, and the description is more specific and detailed, but
it should not be construed as a limitation on the scope of the present disclosure.
It should be noted that for those skilled in the art, the above technical features
can be freely combined and several deformations and improvements can be made without
departing from the conception of the present disclosure, all of which fall within
the scope of the present disclosure. Therefore, all equivalent transformations and
modifications made within the scope of the claims of the present disclosure shall
fall within the scope of coverage of the claims of the present disclosure.
