[0020] Referring now to FIGS. 1-3, an embodiment of the present invention provides an electronic
atomization device 100 with individually replaceable liquid storage assembly, including:
an atomizing assembly 10, a main body assembly 20, and a liquid storage assembly 30.
The liquid storage assembly 30 is configured to store a liquid, the atomizing assembly
10 is configured to heat the liquid, and the main body assembly 20 is configured to
control a heating of the atomizing assembly 10. The liquid storage assembly 30 is
pluggably connected to the atomizing assembly 10, such that the liquid storage assembly
30 can be replaced individually from the atomizing assembly 10.
[0021] In particular, as shown in FIG. 2, the liquid storage assembly 30 includes a liquid
reservoir 32 having a generally hollow cylindrical shape, the liquid is contained
in the liquid reservoir 32. A penetrating channel 331 in the axial direction is also
provided within the liquid reservoir 32 for the passage of ambient air as well as
the generated smoke. Note that axial direction and radial direction herein refer to
axial direction and radial direction of the electronic atomization device 100 respectively.
The configuration of the liquid and channel 331 in this embodiment includes, but is
not limited to, the following forms: a liquid storage element 33 is provided in the
liquid reservoir 32, the liquid is adsorbed by the liquid storage element. The channel
331 is provided in the liquid storage element 33 and the channel 331 extends through
the liquid storage element 33 in the axial direction. It is noted that the liquid
storage element 33 can restrict a flow of the liquid when the channel 331 is not in
communication with the outside (no suction). When the channel 331 is in communication
with the outside, the liquid storage element 33 is able to make the liquid flow at
an appropriate flow rate to the atomizing assembly 10. Preferably, the dimensions
of the liquid storage element 33 are adapted to an internal profile of the liquid
reservoir 32, i.e., the liquid storage element 33 is substantially attached to an
internal wall of the liquid reservoir 32. In this embodiment, the liquid storage element
33 is liquid storage cotton. It will be appreciated that in other embodiments, a liquid
storage element made of one or more of ceramic, microporous ceramic, diatomaceous
earth may also be provided to adsorb the liquid. The liquid storage element 33 is
provided so that liquid can be adsorbed thereon, the fluidity of the liquid can be
reduced and the risk of liquid leakage can be reduced. And during replacing the liquid
storage element 33, the liquid storage element 33 can be placed in the liquid reservoir
32 without inverting the liquid reservoir 32, thereby eliminating burdensome operations
of injecting the liquid and resulting in convenient operation.
[0022] To better seal the liquid reservoir 32, the electronic atomization device of this
embodiment also includes a mouthpiece 40 for a user to smoke, ambient air may enter
the electronic atomization device, and eventually generated smoke may also flow to
the mouthpiece 40. Preferably, as shown in FIG. 2, the mouthpiece 40 is connected
to and seals an upper end in the axial direction of the liquid reservoir 32 (except
for the channel 331). The mouthpiece 40 is also substantially cylindrical and the
channel 331 communicates with the mouthpiece 40. Preferably, the mouthpiece 40 is
made of a silicone material, to effectively seal against the upper end in the axial
direction of the liquid reservoir 32. More preferably, the liquid reservoir 32 and
the mouthpiece 40 are integrated to facilitate processing. Both of the liquid reservoir
32 and the mouthpiece 40 can be manufactured as an integrated product to achieve universal
production and also to facilitate replacement. It will be appreciated that, in other
embodiments, the mouthpiece 40 may take any suitable configuration and may not be
integrally formed with the liquid reservoir 32.
[0023] A lower end in the axial direction of the liquid reservoir 32 is provided with a
third opening 321, the liquid storage assembly 30 further includes a first sealing
gasket 34 for sealing the third opening 321. The first sealing gasket 34 rests on
a lower end face in the axial direction of the liquid storage element 33. The first
sealing gasket 34 is provided with a penetrating first through hole 341 in the axial
direction communicating and coaxial with the channel 331 of the liquid storage element
33, such that the first sealing gasket 34 is allowed to seal the liquid within the
liquid reservoir 32 without obstructing the passage of the gas in the channel 331.
Preferably, a lower end face in the axial direction of the first sealing gasket 34
may also be provided with an annular gasket 31, to further enhance the sealing effect.
[0024] Both ends in the axial direction of the liquid reservoir 32 of the present embodiment
provide effective sealing of the liquid within the liquid reservoir 32 by providing
the mouthpiece 40 and the first sealing gasket 34. It should be note that, when the
liquid reservoir 32 is provided integrally with the mouthpiece 40 as a finished product,
when the liquid reservoir 32 is not in use, the mouthpiece 40 and the first through
hole 341 of the first sealing gasket 34 may be plugged with a sealing plug (not shown)
to prevent evaporation of the liquid therein and to facilitate transport and storage.
Prior to fitting liquid reservoir into the housing 11, the sealing plug may be removed.
[0025] In this embodiment, the main body assembly 20 is electrically connected to the atomizing
assembly 30, and the main body assembly 20 includes a main casing 21, a pneumatic
sensor 26, an electrode 23, a battery 24, and a circuit board 25. The main casing
21 is generally in the shape of a long rod, and is hollow and encases the pneumatic
sensor 26, the positive and negative electrodes 23, the battery 24 and the circuit
board 25. Specific structures, connection relationships, and modes of operation of
the main body assembly 20 will be described in more detail below.
[0026] The atomizing assembly 10 includes a housing 11 and an atomizer 12 which are interconnected,
as shown in FIGS. 2 and 8. The housing 11 is long rod shaped and hollow, and the atomizer
12 is disposed within an internal cavity of the housing 11. An upper end in the axial
direction of the housing 11 is provided with a first opening 1111. The liquid storage
assembly 30 is pluggably disposed within the internal cavity of the housing 11 through
the first opening 1111, such that the liquid storage assembly 30 is encased within
the housing 11. When the liquid storage assembly 30 is inserted into the housing 11,
one end of the atomizer 12 is inserted into the channel 331 of the liquid storage
element 33 such that the atomizer 12 is in contact with the liquid storage assembly
30.
[0027] Since the liquid reservoir 32 is provided separately from the atomizer 12 in the
electronic atomization device of the present embodiment, a middle of the liquid storage
assembly 30 defines a channel 331, the housing 11 of the atomizing assembly 10 is
fixedly connected to the atomizer 12, and the liquid storage assembly 30 is capable
of being pluggably disposed within the housing 11 via the first opening 1111 of the
housing 11, such that when the liquid is exhausted or the liquid storage cotton 33
is damaged, the liquid storage assembly 30 can be pulled out of the housing 11 and
then the liquid storage cotton 33 therein is replaced via the third opening 321, without
replacing the atomizing assembly 20. The liquid storage assembly 30 is enabled to
be individually replaced independently of the atomizing assembly 20. Material waste
is effectively reduced. Once the liquid storage assembly 30 is inserted into the housing
11, the liquid guide column 121 of the atomizer 12 can be inserted into the channel
331 from the bottom of the liquid storage assembly 30, such that the atomizing assembly
10 is in contact with the liquid storage assembly 30. It is not only advantageous
to save space, but also easy and reasonable to assemble.
[0028] Specifically, as shown in FIG. 8, the housing 11 defines first cavity 111and a second
cavity 112 which are oppositely arranged in the axial direction. The first cavity
111 provided with a first opening 1111 facing upwards in the axial direction and dimensions
of the first cavity 111 are adapted to the dimensions of the liquid reservoir 32,
such that the liquid storage assembly 30 can be inserted into or pulled out of the
first cavity 111 through the first opening 1111. The second cavity 112 is provided
with a second opening 1121 facing away from the first opening 1111, and the dimensions
of the second cavity 112 are adapted to the dimensions of the main casing 21, such
that the main body assembly 20 can be inserted into and pulled out of the second cavity
112 through the second opening 1121. Each of the liquid storage assembly 30 and the
main body assembly 20 of the present embodiment is located on one side in the axial
direction of the atomizer 12. The electronic atomization device 100 is assembled by
a two-step operation of inserting the liquid storage assembly 30 into the first cavity
111 and inserting the main body assembly 20 into the second cavity 112. Preferably,
the first cavity 111 and the second cavity 112 are formed integrally in this embodiment.
It will be appreciated that in other embodiments, the first cavity 111 and the second
cavity 112 may also be provided separately.
[0029] Preferably, when the liquid storage assembly 30 is inserted into the housing 11 from
the first opening 1111, the liquid storage assembly 30 may be fully accommodated within
the housing 11, or a portion of the liquid storage assembly 30 is accommodated within
the housing 11 and another portion of the liquid storage assembly 30 is exposed outside
the lower end of the housing 11. Once the lower end of the liquid storage assembly
30 is in contact with the upper end of the atomizing assembly 10, the liquid storage
assembly 30 may be inserted into the lower end of the atomizing assembly 10 and secured
within the housing 11, or attracted and fixed to the lower end of the atomizing assembly
10, or snapped onto the inner wall of the housing 11. Preferably, when the liquid
storage assembly 30 is provided inside the housing 11, the mouthpiece 40 is located
outside the housing 11. The user may pull the liquid storage assembly 30 out of the
first cavity 111 by applying a force to the mouthpiece 40.
[0030] As shown in FIGS. 5 to 7, an outer side wall of the liquid reservoir 32 is provided
with a first bump 322 and an inner side wall of the housing 11 is provided with a
first groove 113 in a position corresponding to the first bump 322. The first groove
113 is configured to receive the first bump 322. When the liquid storage assembly
30 is accommodated in the first cavity 111, the first bump 322 is snap-fitted into
the first groove 113. Such configuration is effective to prevent the liquid storage
assembly 30 from falling out of the housing 11 during use. It will be appreciated
that a snapping force between the first bump 322 and the first groove 113 is limited,
when an outward force applied by a hand on the mouthpiece 40 is greater than this
snapping force, the liquid storage assembly 30 can then be pulled out of the housing
11e. Preferably, an inner wall face of the first groove 113 is circular arc shaped,
correspondingly an outer wall face of the first bump 322 is circular arc shaped. It
is easier to pull out the liquid storage assembly 30 by the abutting fit between the
circular arcs of the first bump 322 and the first groove 113.
[0031] As shown in FIGS. 2-3, the atomizer 12 includes a liquid guide column 121 and a fixing
seat 122 that are interconnected. The liquid guide column 121 and the fixing seat
122 together define a penetrating tunnel 125 in the axial direction. The tunnel 125
is in communication with the channel 331. An atomizing wick 124 is provided within
the tunnel 125. A wall of the liquid guide column 121 is provided with a penetrating
liquid inlet 1211 in the radical direction, the atomizing wick 124 is positioned at
the liquid inlet 1211. The liquid inlet 1211 is in communication with the channel
125, so that liquid within the liquid storage element 33 can flow from the liquid
inlet 1211 of the liquid guide column 121 to the atomizing wick 124 and be heated
by the atomizing wick 124 into a smoke which can then flow through the channel 331
to the mouthpiece 31 to be inhaled by a user. In this embodiment, when the atomizer
12 is inserted into the channel 331 of the liquid storage element 33, the liquid storage
element 30 surrounds and rests on the periphery of one end of the atomizer 12 inserted
into the channel 33.
[0032] In particular, the liquid guide column 121 is hollow cylinder shaped, and the fixing
seat 122 is circular table shaped and is located below the liquid guide column 121
in the axial direction, such that the atomizer 12 has the overall shape of letter
T upside down. The fixing seat 122 is for fixed connection with the housing 11. When
the liquid storage assembly 30 is inserted into the housing 11 from the first opening
1111, the fixing seat 122 holds the liquid storage element 33 and the first sealing
gasket 34 and the gasket 31 arranged on a lower end face in the axial direction of
the liquid storage element 33 at the third opening 321, while the liquid guide column
121 of the atomizer 12 is inserted into the channel 331 of the liquid storage element
33. A radial dimension of the fixing seat 122 is adapted to that of the liquid storage
element 33, and the radial dimension of the liquid guide column 121 is adapted to
the radial dimension of the channel 331. When liquid guide column 121 is inserted
into channel 331, the outer wall of liquid guide column 121 abuts against the inner
wall of channel 331. This configuration, on the one hand, prevents leakage of the
liquid from the gap between the liquid guide column 121 and the channel 331, and,
on the other hand, allows the liquid guide column 121 to be securely encased by the
liquid storage element 33 to enhance its robustness. Preferably, an inner diameter
of a first through hole 341 of the first sealing gasket 34 is adapted to an outer
diameter of the liquid guide column 121, such that when the liquid storage assembly
30 is inserted into the first cavity 111, the liquid guide column 121 abuts against
the first through hole 341, to enhance the sealing and reduce leakage of the liquid.
[0033] Preferably, the guide ring 126 is provided at an upper end in the axial direction
of the liquid guide column 121, the radial dimension of the guide ring 126 is slightly
smaller than the radial dimension of the liquid guide column 121, and preferably the
radial dimension thereof tapers in a direction away from the liquid guide column 121.
This arrangement allows smooth insertion of the liquid guide column 121 into the channel
331. Preferably, an upper edge of the liquid inlet 1211 is provided with a liquid
guide port 1212, the liquid guide port 1212 is strip shaped, and extends away from
the fixing seat 122 in the axial direction. The liquid guide port 1212 can increase
the liquid guide velocity of the liquid and facilitate evacuation of air bubbles from
the liquid. More preferably, the axial middle of the liquid inlet 1211 is provided
with a connecting strip 1213 extending from one side of the liquid inlet 1211 to an
opposite side in a circumferential direction, to prevent deformation of the liquid
storage element 33 by the tension of the liquid guide column 121 from the heating
expansion.
[0034] To avoid leakage of liquid downward from the fixing seat 122, as shown in FIG. 3,
the fixing seat 122 is provided with a first stop 1221 convex toward the liquid storage
assembly 30, the first stop 1221 has a smaller dimension than those of the other portions
of the fixing seat 122. And the dimension of the first stop 1221 are adapted to the
dimension of the fourth opening 321 of the liquid reservoir 32, such that when the
liquid storage assembly 30 is inserted into the first cavity 111, an end face of the
first stop 1221 in the axial direction closes the fourth opening 321 (except for the
channel 331) and a peripheral wall of the first stop 1221 abuts against the inner
wall of the liquid reservoir 32, thereby effectively reducing leakage of the liquid.
[0035] The atomizing assembly 10 may also be provided with a second sealing gasket 13. Referring
to FIG. 2, the fixing seat 122 is with a third cavity 1222 recessed away from the
main body assembly 20, the second sealing gasket 13 is disposed within the third cavity
1222. The second sealing gasket 13 is also provided with a second through hole 131
communicating with the tunnel 125 for conducting a gas flow. When the main body assembly
20 is inserted into the second cavity 112, the second sealing gasket 13 separates
the main body assembly 20 from the atomizing assembly 10, to prevent the liquid in
the liquid reservoir 32 from leaking through the gaps between the components and contaminating
the other components. Preferably, as shown in FIG. 3, an end face of the second sealing
gasket 13 facing the fixing seat is concavely provided with a fourth cavity 131, an
absorbent cotton 14 is provided in the fourth cavity 131. The absorbent cotton 14
abuts against the fixing seat 122 and the second sealing gasket 13 respectively, for
absorbing liquid or condensed water flowing from the tunnel 125 to the second sealing
gasket 13.
[0036] To enhance the stability of the connection between the atomizer 12 to the housing
11, referring to FIGS. 2, 8 and 9, a peripheral wall of the fixing seat 122 is convexly
provided with a hook 1223, and the housing 11 is provided with a penetrating clamping
opening 115 in the radical direction at a position corresponding to the hook 1223.
The clamping opening 115 is configured to receive the hook 1223, and the fixing seat
122 can be secured to the housing 11 by connection of the clamping opening 115 to
the hook 1223. The hook 1223 is preferably made of a resilient material, the fixing
seat 122 can be disengaged from the housing 11 when the hook 1223 is forced to disengage
from the clamping opening 115. Preferably, the number of the hook 1223 is two, the
two hooks 1223 are symmetrically disposed on the peripheral wall of the fixing seat
122 in the radial direction. Correspondingly, two clamping openings 115 are also provided,
so that the fixing seat 122 is more evenly forced when disengaged and easily disengaged
from the housing 11. Preferably, as shown in FIG. 9, the inner wall of the housing
11 can also be concavely provided with a second stop 116, the second stop 116 can
hold a portion of a bottom end of the fixing seat 122, to prevent the fixing seat
122 from running downward in the axial direction.
[0037] In this embodiment, when the main body assembly 20 is inserted into the second cavity
112 through the second opening 1121, the main body assembly 20 establishes an electrical
connection with the atomizing assembly 10. Specifically, as shown in FIGS. 2-4, the
atomizer 12 includes two pins 123 extending downwardly in the axial direction, the
pins 123 are connected with an atomizing wick 124. The second sealing gasket 13 is
provided with two plug holes 132 extending in the axial direction. The pins 124 pass
through the absorbent cotton 14 in the fourth cavity 131 and are bent into the plug
holes 132 respectively. As shown in FIGS. 2 and 10, the main casing 21 is open at
its upper end and receives a holder 22 defining a pneumatic sensor cavity 211, a battery
cavity 222 and a circuit board holder 223 which are configured to receive the pneumatic
sensor 26, the battery 24 and the circuit board 25 respectively. The main casing 21
encases the holder 22 and the components within the holder 22 for protection. The
circuit board 25 is electrically connected with the pneumatic sensor 26 and the battery
24. The pneumatic sensor cavity 211 is located below the second through hole 131 in
the axial direction and communicates with the tunnel 125, and the battery cavity 222
and the circuit board holder 223 are located below the pneumatic sensor cavity 211
in the axial direction. The positive and negative electrodes 23 protrude from the
main casing 21. When the main body assembly 20 is inserted into the second cavity
112, the positive and negative electrodes 23 are inserted into the plug holes 132
of the second sealing gasket 13, to connect with the pins 123, thereby establishing
an electrical connection with the atomizing wick 124 of the atomizer 12. When the
mouthpiece 40 is sucked, ambient air flows through the pneumatic sensor cavity 211
and triggers the pneumatic sensor 26, the pneumatic sensor 26 sends a trigger signal
to the circuit board 25, thereby driving the atomizing wick 124 to heat the liquid
to generate smoke.
[0038] Once the main body assembly 20 is inserted into the second cavity 112 of the housing
11 from the second opening 1113, the main body assembly 20 may be fully received within
the housing 11 or partially received within the housing 11, or partially received
within the housing 11 and partially exposed from the lower end of the housing 11.
Once the upper end of the main body assembly 20 is in contact with the lower end of
the atomizing assembly 10, the main body assembly 20 may be plugged onto the lower
end of the atomizing assembly 10 and secured within the second chamber 112, or attracted
and fixed to the lower end of the atomizing assembly 10, or clamped onto the inner
wall of the housing 11. Since the main casing 21 of the main body assembly 20 is clamped
internally in this embodiment, no other components inside are visible when the main
body assembly 20 is inserted into the second cavity 112, which makes the overall look
more aesthetically pleasing. At the same time, since main body assembly 20 is pluggable,
it is easier to clean the condensate from the main body assembly 20 after the main
body assembly 20 is pulled out. The main body assembly 20 in the prior art is complex
to assemble and disassemble, inconvenient to clean, and costly to maintain.
[0039] As one embodiment, the main body assembly 20 of the present embodiment is received
in the second cavity 112 and is partially exposed from the lower end of the second
opening 1121 of the housing 11, and the exposed portion of the main body assembly
20 forms a pull-out portion 215. The pull-out portion 215 is exposed from the lower
end of the housing 11, so that when the entire main body assembly 20 needs to be replaced,
the main body assembly 20 is pulled out as a whole by applying a force to the pull-out
portion 215 in a direction away from the second opening 1121. The circuit board holder
223 is located in an area where the pull-out 215 is located. And a lower end of the
pull-out portion 215 in the axial direction may be provided with a charging port 211
configured to charge the battery 24 while also configured for intake.
[0040] Preferably, the upper end of the pull-out portion 215 is provided with a third stop
2151 configured to contact with the lower end of the housing 11, and an outer edge
of the third stop 2151 is flush with the outer edge of the lower end of the housing
11 after contact. The third stop may prevent over insertion of the main body assembly
20 into the housing 11 and damage to the atomizing assembly 10. At the same time,
the outer edge of the third stop is flush with the outer edge of the lower end of
the housing 11, so that the housing 11 and the pull-out portion 215 appear integral
from outside, which makes the entire atomization device more aesthetically pleasing.
[0041] As shown in FIGS. 5 to 7, the outer side wall of the main casing 21 is convexly provided
with a second bump 214. The inner side wall of the housing 1 1 is provided with a
second groove 114 in a position corresponding to the second bump 214. The second bump
214 is snap-fitted into the second groove 114 when the main body assembly 20 is received
within the second cavity 112. Such configuration is effective to prevent the main
body assembly 20 from falling out of the housing 11 during use. As it will be appreciated,
the main body assembly 20 may then be pulled out of the housing 11 when an outward
force applied on the pull-out portion 213 by a hand is greater than this snapping
force. Preferably, the inner wall face of the second groove 114 are circular arc shaped,
correspondingly the outer wall face of the second bump 214 are circular arc shaped.
It is easier to pull out the liquid storage assembly 30 by the abutting fit between
the circular arcs of the second bump 214 and the second groove 114.
[0042] The housing 11 of the electronic atomization device 100 of the present embodiment
may also be provided with a decorative sticker. The users can change the decorative
sticker according to their own preferences, to achieve a refreshing new visual experience.
[0043] The electronic atomization device 100 of the present embodiment operates as follows:
the liquid storage assembly 30 is inserted into the first cavity 111 and the atomizer
12 is inserted into the channel 331; the main body assembly 20 is inserted into the
second cavity 112 and then the mouthpiece 40 may be sucked to allow the atomizer 12
to operate.
[0044] When the liquid is exhausted or the liquid storage element 33 is damaged, the liquid
storage element 33 can be replaced by simply pulling the liquid storage assembly 30
out of the first opening 1111 and removing the first sealing gasket 34; when there
is a failure in the atomizer 12, the atomizer 12 can be removed and replaced individually
by simply removing the liquid storage assembly 30 from the first opening 1111 and
then applying force to the hook 1223 to disengage the fixing seat 122 from the housing
11; when there is a failure in the main body assembly 20, the main body assembly 20
may simply be pulled out of the second opening 1121 to be replaced or serviced.
[0045] This embodiment not only facilitates space saving but also is aesthetically pleasing
by providing the electronic atomization device 100 as three separate assemblies of
the liquid storage assembly 30, the main body assembly 20, and the atomizer 12, and
pluggably connecting the liquid storage assembly 30, the main body assembly 20, and
the atomizer 12 to the housing 11. Also, the assembly is simple and reasonable, the
assembly of the entire electronic atomization device 100 can be completed by simple
two-step insertion (insertion of the liquid storage assembly 30 into the first cavity
111 and insertion of the main body assembly 20 into the second cavity 112). In addition,
each of the three assemblies can be individually replaced and reused multiple times,
which effectively reduces material waste. And the three assemblies are structurally
complete and can be prepared in alternative inner container formats to achieve universal
production.
