[0012] As shown in FIG. 1 to FIG. 6, an electronic atomization device 100 includes an upper
housing 10, a first sealing member 11, a second sealing member 12, a base 13, a conveying
tube 14, an atomization core 15, a sleeve 16, a suction nozzle 17, an e-liquid absorption
member 18, a e-liquid storage member 19, a lower housing 20, a battery cell 21, an
air flow sensor 22, and a shell 23.
[0013] Upper and lower ends of the upper housing 10 are open ends. The first sealing member
11 is arranged at an upper end of the upper housing 10, and the second sealing member
12 is arranged at a lower end of the upper housing 10.
[0014] The first sealing member 11 and the second sealing member 12 are both made of sealing
materials, such as silica gel.
[0015] An outer side wall of the first sealing member 11 has a protruding portion 111 that
extends in a radial direction, and a portion of the first sealing member 11 located
below the protruding portion 111 extends into the upper housing 10. The outer side
wall of the first sealing member 11 is abutted against an inner side wall of the upper
housing 10 to achieve sealing. Further, the outer side wall of the first sealing member
11 has a convex ring, to achieve a good sealing effect with the inner side wall of
the upper housing 10. An end surface of the upper end of the upper housing 10 is abutted
against a lower surface of the protruding portion 111 to achieve sealing.
[0016] Similarly, an outer side wall of the second sealing member 12 has a protruding portion
121 that extends in the radial direction, and a portion of the second sealing member
12 located above the protruding portion 121 extends into the upper housing 10. The
outer side wall of the second sealing member 12 is abutted against the inner side
wall of the upper housing 10 to achieve sealing. Further, the outer side wall of the
second sealing member 12 has a convex ring, to achieve a good sealing effect with
the inner side wall of the upper housing 10. An end surface of the lower end of the
upper housing 10 is abutted against an upper surface of the protruding portion 121
to achieve sealing.
[0017] The first sealing member 11 has a through hole 112, and the second sealing member
12 has a through hole 122. A lower end of the base 13 is accommodated or held in the
through hole 122. An upper end of the conveying tube 14 is accommodated or held in
the through hole 112, and a lower end of the conveying tube 14 is accommodated in
the base 13 and is abutted against an end surface of an upper end of the atomization
core 15. In this way, a vent tube formed by the base 13 and the conveying tube 14
jointly form an air flow channel of the electronic atomization device 100.
[0018] The base 13 internally has an accommodating cavity configured to accommodate the
atomization core 15. A side wall of the base 13 has an e-liquid passing hole 131 that
communicates an e-liquid storage cavity to the atomization core 15, and a sleeve 16
sleeves the base 13 and the conveying tube 14. The sleeve 16 can absorb the e-liquid
matrix stored in the e-liquid storage cavity and convey the e-liquid matrix to the
atomization core 15 through the e-liquid passing hole 131. In another example, the
sleeve 16 may alternatively be omitted.
[0019] The atomization core 15 is close to the second sealing member 12. The atomization
core 15 includes an e-liquid guide element 151 and a heating element 152. The e-liquid
guide element 151 may be, for example, a cotton fiber, a metal fiber, a ceramic fiber,
a glass fiber, or cellular ceramic, and is preferably made of the cotton fiber and
constructed into a tubular structure extending in a longitudinal direction of the
electronic atomization device 100. The heating element 152 is a heating mesh made
of a resistive material. The heating element 152 may be arranged on an inner wall
of the e-liquid guide element 151.
[0020] In other examples, the atomization core 15 may extend in a transverse direction of
the electronic atomization device 100. For example: the heating element 152 transversely
passes through the base 13 after being wrapped around the e-liquid guide element 151.
The heating element 152 is arranged in the base 13, and two ends of the e-liquid guide
element 151 may extend into the e-liquid storage cavity.
[0021] An aerosol generated by heating and atomization by the atomization core 15 may be
conveyed to the suction nozzle 17 through the conveying tube 14.
[0022] A portion of the first sealing member 11 located above the protruding portion 111
extends into the suction nozzle 17, and an end surface of a lower end of the suction
nozzle 17 is abutted against an upper surface of the protruding portion 111 to achieve
sealing. The suction nozzle 17 has a connection tube 171 extending downward from a
mouth piece end, and the connection tube 171 communicates with the through hole 112.
In this way, the aerosol generated by heating and atomization by the atomization core
15 may flow out of the mouth piece end through the conveying tube 14, the through
hole 112, and the connection tube 171. In a further implementation, the first sealing
member 11 has a first groove 113. The e-liquid absorption member 18 is arranged in
the first groove 113. The e-liquid absorption member 18 has a channel for an air flow
to pass through. In this way, the e-liquid absorption member 18 can absorb the e-liquid
matrix that is condensed in the suction nozzle 17.
[0023] A gap between the upper housing 10, the first sealing member 11, the second sealing
member 12, the base 13, and the conveying tube 14 forms the e-liquid storage cavity
(not shown) for storing the e-liquid matrix.
[0024] The first sealing member 11 further has a second groove 114, and the second groove
114 limits or forms a first e-liquid storage space of the e-liquid storage cavity.
The second sealing member 12 has a groove 123, and the groove 123 limits or forms
a second e-liquid storage space of the e-liquid storage cavity. A portion of the e-liquid
storage cavity between the first e-liquid storage space and the second e-liquid storage
space limits or forms a third e-liquid storage space. The first e-liquid storage space,
the third e-liquid storage space, and the second e-liquid storage space are arranged
in sequence in the longitudinal direction of the electronic atomization device 100.
[0025] The e-liquid storage member 19 is arranged or accommodated in the third e-liquid
storage space, and the e-liquid storage member 19 does not extend into the first e-liquid
storage space or the second e-liquid storage space. The e-liquid storage member 19
is preferably made of a cotton fiber. The e-liquid storage member 19 is configured
to adsorb the e-liquid matrix, to hold at least a portion of the e-liquid matrix in
the third e-liquid storage space. The e-liquid storage member 19 has a through hole
(not shown) penetrating through an upper end and a lower end of the e-liquid storage
member, to sleeve the base 13 and the conveying tube 14. The e-liquid storage member
19 may be in contact with an end surface of a lower end of the first sealing member
11 and/or an end surface of an upper end of the second sealing member 12, to be maintained
between the first sealing member 11 and the second sealing member 12.
[0026] In other examples, the first sealing member 11 does not form the first e-liquid storage
space, namely, the e-liquid storage cavity includes a portion of the e-liquid storage
space basically located in the upper housing 10 and the other portion of the e-liquid
storage space formed in the second sealing member 12. On the contrary, it is also
feasible that the second sealing member 12 does not form the second e-liquid storage
space and the first sealing member 11 forms the first e-liquid storage space.
[0027] A volume of the first e-liquid storage space and a volume of the second e-liquid
storage space are both less than a volume of the third e-liquid storage space. Preferably,
the volume of the first e-liquid storage space is greater than the volume of the second
e-liquid storage space. Generally, the volume of the first e-liquid storage space
and the volume of the second e-liquid storage space are both between 1 ml and 4 ml.
Preferably, the volumes are between 1 ml and 3 ml. A ratio of the volume of the third
e-liquid storage space to the volume of the first e-liquid storage space is between
5 and 8. Preferably, the ratio is between 5 and 7. A ratio of the volume of the third
e-liquid storage space to the volume of the second e-liquid storage space is similar
to the above ratio. Specifically for example, the volume of the third e-liquid storage
space may be 10 ml; the volume of the second e-liquid storage space may be 2 ml; and
the volume of the first e-liquid storage space may be 3 ml. In this way, the first
e-liquid storage space formed in the first sealing member 11 and the second e-liquid
storage space formed in the second sealing member 12 enlarge the volume of the e-liquid
storage cavity in the existing electronic atomization device, thereby enhancing the
user experience.
[0028] A side wall of the first e-liquid storage space is inclined to the longitudinal direction
of the electronic atomization device 100, and a side wall of the second e-liquid storage
space is inclined to the longitudinal direction of the electronic atomization device
100. An angle between the side wall of the first e-liquid storage space and the longitudinal
direction of the electronic atomization device 100 is between 10° and 20° (preferably,
between 12° and 20°; further preferably, between 14° and 20°; still further preferably,
between 14° and 18°; further preferably, 14° to 16°). An angle between the side wall
of the second e-liquid storage space and the longitudinal direction of the electronic
atomization device 100 is between 10° and 20° (preferably, between 12° and 20°; still
further preferably, between 14° and 20°; still further preferably, between 14° and
18°; still further preferably, 14° to 16°). In this way, when the electronic atomization
device 100 is placed vertically (as shown in FIG. 2), a portion of the e-liquid matrix
in the e-liquid storage cavity may be stored in the second e-liquid storage space,
and the e-liquid matrix stored in the first e-liquid storage space may flow towards
the e-liquid storage member through the inclined side wall. When the electronic atomization
device 100 is placed upside down (after the direction shown in FIG. 2 is rotated 180°),
the portion of the e-liquid matrix in the e-liquid storage cavity may be stored in
the first e-liquid storage space, and the e-liquid matrix stored in the second e-liquid
storage space may flow towards the e-liquid storage member through the inclined side
wall. In this way, the e-liquid matrix can be prevented from being accumulated at
one end of the e-liquid storage member 19 to cause leakage of the e-liquid matrix
from the e-liquid passing hole 131.
[0029] Further, a first capillary slot 114a is provided in a side wall of the first e-liquid
storage space, and the first capillary slot 114a extends from a top wall of the first
e-liquid storage space in a direction towards the second e-liquid storage space. A
second capillary slot 123a is provided in a side wall of the second e-liquid storage
space; and the second capillary slot 123a extends from a bottom wall of the second
e-liquid storage space in a direction towards the first e-liquid storage space. A
width of the first capillary slot 114a is between 0.1 mm and 1 mm (preferably, between
0.1 mm and 0.8 mm; preferably, between 0.1 mm and 0.7 mm; preferably, between 0.2
mm and 0.7 mm; preferably, between 0.4 mm and 0.7 mm; preferably, 0.5 mm and 0.7 mm),
and a width of the second capillary slot 123a is between 0.1 mm to 1 mm (preferably,
between 0.1 mm and 0.8 mm; preferably, between 0.1 mm and 0.7 mm; preferably, between
0.2 mm and 0.7 mm; preferably, between 0.4 mm and 0.7 mm; preferably, between 0.5
mm and 0.7 mm).
[0030] An upper end of the lower housing 20 is an open end, and a lower end is a closed
end. An end surface of the upper end of the lower housing 20 is abutted against a
lower surface of the protruding portion 121 to achieve sealing. The shell 23 sleeves
the upper housing 10 and the lower housing 20. An end surface of an upper end of the
shell 23 is abutted against a surface of a portion, which protrudes outwards in the
radial direction, of the suction nozzle 17. An end surface of a lower end of the shell
23 is abutted against a surface of a portion, which protrudes outwards in the radial
direction, of the lower housing 20. Both the protruding portion 111 and the protruding
portion 121 may be abutted against an inner surface of the shell 23 to achieve sealing.
The upper housing 10, the lower housing 20, and the shell 23 form a housing assembly
of the electronic atomization device 100. In other examples, it is also feasible that
no shell 23 is provided. In other examples, the upper housing 10, the lower housing
20, and the shell 23 may be integrally formed.
[0031] The battery cell 21 is arranged in the lower housing 20 and is located below the
second sealing member 12. The battery cell 21 supplies electric power for operating
the electronic atomization device 100. The battery cell 21 may be a rechargeable battery
or a disposable battery. Preferably, the rechargeable battery is used.
[0032] An air inlet is provided in the closed end of the lower housing 20. External air
flows into the electronic atomization device 100 through the air inlet, and then flows
into the atomization core 15 through the through hole 122. The external air and the
aerosol generated by heating and atomization flow out of the mouth piece end of the
suction nozzle 17 together after passing through the conveying tube 14, the through
hole 112, and the suction nozzle 17 in sequence.
[0033] An accommodating cavity is further arranged in the lower housing 20, and the air
flow sensor 22 is accommodated in the accommodating cavity. The air flow sensor 22,
for example, a microphone, controls, when sensing that the electronic atomization
device 100 is vaped, the atomization core 15 to start to work.
[0034] It should be noted that, in the examples shown in FIG. 1 to FIG. 6, the electronic
atomization device 100 is integrated. In other examples, the electronic atomization
device 100 may be a cylinder or an atomizer used in combination with a power supply
device. For example, the electronic atomization device 100 and the power supply device
are detachably connected. The upper housing 10, the first sealing member 11, the second
sealing member 12, the base 13, the conveying tube 14, the atomization core 15, the
sleeve 16, the suction nozzle 17, the e-liquid absorption member 18, and the e-liquid
storage member 19 may be arranged in the electronic atomization device 100. The lower
housing 20, the battery cell 21, and the air flow sensor 22 are arranged in the power
supply device.
