hole 1522 is in communication with the vaporization cavity 125 to be further in communication
with the external air through the air inlet hole 126 at the bottom of the vaporization
cavity 125.
[0092] In another embodiment, referring to FIG. 21, FIG. 21 is a schematic structural diagram
of a ninth embodiment of a vent channel in an electronic vaporization device according
to this application. The air guide groove structure 151 further includes a third air
guide groove 1513 and a fourth air guide groove 1514. An end of the third air guide
groove 1513 is in communication with the first air guide hole 1521, and another end
is in communication with the liquid flowing hole 111. An end of the fourth air guide
groove 1514 is in communication with the second air guide hole 1522, and another end

can guide the air transmitted in the first air guide groove 1511 to flow through the
liquid flowing hole 111, and the fourth air guide groove 1514 can guide the air transmitted
in the second air guide groove 1512 to flow through the liquid flowing hole 111, so
that the first air guide hole 1521, the second air guide hole 1522, and the liquid
flowing hole 111 perform air transmission at the same time, thereby shortening a duration
for balancing the air pressure in the liquid storage tank 4 and the external air pressure.
[0093] In another embodiment, an end of the first air guide groove 1511 is in communication
with the vaporization cavity 125 or the external air, and another end is in communication
with the first air guide hole 1521. An end of the third air guide groove 1513 is in
direct communication with the vaporization cavity 125 or the external air, and another

cavity 125 or the external air, and another end is in communication with the liquid
flowing hole 111.
[0094] The liquid in the liquid storage tank 4 flows to the vaporization core 2 through
the liquid flowing hole 111. If the air pressure in the liquid storage tank 4 decreases,
a speed at which the liquid in the liquid storage tank 4 flows to the vaporization
core 2 through the liquid flowing hole 111 is less than a speed at which the vaporization
core 2 vaporizes the liquid. Air is guided to the liquid storage tank 4 through the
vent channel 15, to balance the air pressure in the liquid storage tank 4 and the
external air pressure.
[0095] In a specific embodiment, a user inhales the electronic vaporization device 100.
The vaporization core 2 vaporizes e-liquid, the air pressure in the vaporization cavity
125 is greater than the air pressure in the liquid storage tank 4, the vaporization
cavity 125 is in communication with the external air, and the external air enters
the vaporization cavity 125 through the air inlet hole 126. The air in the vaporization
cavity 125 is pressed into the first air guide groove 1511 and the second air guide
groove 1512 due to an air pressure difference, the air in the first air guide groove
1511 enters the liquid storage tank 4 through the first air guide hole 1521, the air
in the second air guide groove 1512 enters the liquid storage tank 4 through the second
air guide hole 1522, and the air is guided to the liquid storage tank 4 through the
first air guide hole 1521 and the second air guide hole 1522. Therefore, the air pressure
in the liquid storage tank 4 and the air pressure in the vaporization cavity 125 are
balanced, and the e-liquid in the liquid storage tank 4 further enters the vaporization
core 2 through the liquid flowing hole 111, so that the e-liquid in the liquid storage
tank 4 can be smoothly transmitted to the vaporization core 2 through the liquid flowing
hole 111, thereby avoiding dry burning of the vaporization core 2.
[0096] In a specific embodiment, a user inhales the electronic vaporization device 100.
The vaporization core 2 vaporizes e-liquid, the external air pressure is greater than
the air pressure in the liquid storage tank 4, and the external air is pressed into
the first air guide groove 1511 and the second air guide groove 1512 due to an air
pressure difference. The air in the first air guide groove 1511 enters the liquid
storage tank 4 through the first air guide hole 1521, the air in the second air guide
groove 1512 enters the liquid storage tank 4 through the second air guide hole 1522,
and the air is guided to the liquid storage tank 4 through the first air guide hole
1521 and the second air guide hole 1522. Therefore, the air pressure in the liquid
storage tank 4 and the external air pressure are balanced, and the e-liquid in the
liquid storage tank 4 further enters the vaporization core 2 through the liquid flowing
hole 111, so that the e-liquid in the liquid storage tank 4 can be smoothly transmitted
to the vaporization core 2 through the liquid flowing hole 111, thereby avoiding dry
burning of the vaporization core 2.
[0097] In a specific embodiment, a user inhales the electronic vaporization device 100.
The vaporization core 2 vaporizes e-liquid, the air pressure in the vaporization cavity
125 is greater than the air pressure in the liquid storage tank 4, the vaporization
cavity 125 is in communication with the external air, the external air enters the
vaporization cavity 125 through the air inlet hole 126, the air in the vaporization
cavity 125 is pressed into the first air guide groove 1511 and the second air guide
groove 1512 due to an air pressure difference, and the air in the first air guide
groove 1511 enters the liquid storage tank 4 through the first air guide hole 1521.
When an amount of the air transmitted by the first air guide groove 1511 is greater
than an amount of the air transmitted by the first air guide hole 1521, the third
air guide groove 1513 transmits air, which is not transmitted in the first air guide
groove 1511, to the liquid storage tank 4 through the liquid flowing hole 111. When
an amount of the air transmitted by the second air guide groove 1512 is greater than
an amount of the air transmitted by the second air guide hole 1522, the fourth air
guide groove 1514 transmits air, whichis not transmitted in the second air guide groove
1512, to the liquid storage tank 4 through the liquid flowing hole 111. Since the
first air guide hole 1521, the second air guide hole 1522, and the liquid flowing
hole 111 transmit air to the liquid storage tank 4, the air pressure in the liquid
storage tank 4 and the air pressure in the vaporization cavity 125 are balanced, and
the e-liquid in the liquid storage tank 4 further enters the vaporization core 2 through
the liquid flowing hole 111, so that the e-liquid in the liquid storage tank 4 can
be smoothly transmitted to the vaporization core 2 through the liquid flowing hole
111, thereby avoiding dry burning of the vaporization core 2.
[0098] The vaporizer 10 further includes a seal member 3, and the seal member 3 is provided
between the mounting base 1 and the vaporization core 2. The seal member 3 may be
a seal ring. The porous substrate 21 is made of any one of a porous ceramic or a porous
metal.
[0099] The porous substrate 21 is in communication with the liquid stored in the liquid
storage tank 4 and absorbs the liquid from the liquid storage tank 4 through the capillary
force; and the heating element 22 is configured to heat and vaporize the liquid of
the porous substrate 21. In an embodiment, the porous substrate 21 includes an e-liquid
transmission portion 211 and a protruding portion 212 integrally formed on a side
of the e-liquid transmission portion 211, and the leaked liquid buffer structure 122
is in contact with a periphery of a side surface of the e-liquid transmission portion
211 provided with the protruding portion 212. A surface of the protruding portion
212 away from the e-liquid transmission portion 211 is a vaporization surface 214,
a surface of the e-liquid transmission portion 211 in contact with the e-liquid is
a liquid absorbing surface 213, and the leaked liquid buffer structure 122 is in contact
with an edge of the side surface of the e-liquid transmission portion 211 provided
with the protruding portion 212. That is, the leaked liquid buffer structure 122 is
provided in contact with the edge of the e-liquid transmission portion 211 and is
spaced apart from the protruding portion 212, so that the leaked liquid buffer structure
122 can be prevented from being damaged due to a high temperature of the heating element
22 on the vaporization surface 214. The heating element 22 is provided on the vaporization
surface 214. Specifically, the heating element 22 may be a heating film or may be
a heating circuit. In a specific embodiment, the heating element 22 is electrically
connected to an electrode, and an end of the electrode passes through a foundation
base 121 to be connected to the power supply component 202. Specifically, the e-liquid
transmission portion 211 and the protruding portion 212 are integrally formed, and
the e-liquid transmission portion 211 and the protruding portion 212 are both made
of porous materials. For example, the materials of the e-liquid transmission portion
211 and the protruding portion 212 may be a porous ceramic or a porous metal, but
are not limited to the two materials, provided that the e-liquid in the liquid storage
tank 4 can be transmitted to the heating element 22 through the capillary force to
be vaporized. The e-liquid transmission portion 211 only covers a part of the leaked
liquid buffer structure 122. The capillary force of the porous substrate 21 is greater
than the capillary force of the leaked liquid buffer structure 122, and when the heating
element 22 heats and vaporizes the liquid of the porous substrate 21, the liquid received
by the leaked liquid buffer structure 122 may reflux to the porous substrate 21 and
is heated and vaporized.
[0100] The mounting base 1 includes the vaporization cavity 125, the vaporization core 2
is accommodated in the vaporization cavity 125, and the leaked liquid buffer structure
122 is connected to the bottom of the vaporization cavity 125 and absorbs liquid deposited
at the bottom of the vaporization cavity 125 through a capillary force. The mounting
base 1 includes the upper base body 11 and the lower base body 12. The lower base
body 12 includes the foundation base 121, the liquid flowing hole 111 is provided
on the upper base body 11, the e-liquid in the liquid storage tank 4 flows to the
porous substrate 21 through the liquid flowing hole 111. The leaked liquid buffer
structure 122 is provided on the lower base body 12, the porous substrate 21 includes
the liquid absorbing surface 213 and the vaporization surface 214, the liquid absorbing
surface 213 is connected to the liquid flowing hole 111, the heating element 22 is
provided on the vaporization surface 214, and the porous substrate 21 is in contact
with the leaked liquid buffer structure 122.
[0101] When the air pressure in the liquid storage tank 4 increases, the air pressure in
the liquid storage tank 4 is greater than the air pressure in the vaporization cavity
125, an air pressure difference between the liquid storage tank 4 and the vaporization
cavity 125 presses the liquid in the liquid storage tank 4 to the porous substrate
21, so that redundant liquid overflows out of the porous substrate 21, and the leaked
liquid buffer structure 122 receives and locks the overflowed redundant liquid. When
the air pressure in the liquid storage tank 4 decreases, the air pressure in the liquid
storage tank 4 is less than the air pressure in the vaporization cavity 125, the air
pressure difference between the liquid storage tank 4 and the vaporization cavity
125 enables the liquid in the leaked liquid buffer structure 122 to reflux, due to
the capillary force, to the porous substrate 21 in contact with the leaked liquid
buffer structure, and the porous substrate 21 enables the liquid to reflux to the
liquid storage tank 4.
[0102] In this embodiment, the upper base body 11 and the lower base body 12 are integrally
formed. Alternatively, a groove 112 may be provided on the upper base body 11, and
a clamp member 124 is provided on an outer side wall of the lower base body 12 and
is configured to be clamped to the groove 112 on the upper base body 11, so that the
lower base body 12 is fixedly connected to the upper base body 11.
[0103] A material of the leaked liquid buffer structure 122 is a porous material, and the
porous material may be a hard porous material or may be a soft porous material.
[0104] When the material of the leaked liquid buffer structure 122 is the hard porous material,
in order to save space, the leaked liquid buffer structure 122 can be also configured
to support the vaporization core 2. The hard porous material is at least one of a
porous ceramic or a porous metal, or may be another material with a supporting capability
and a liquid absorbing capability.
[0105] Referring to FIG. 22, FIG. 22 is a schematic structural diagram of a first embodiment
of a leaked liquid buffer structure according to this application. In a specific embodiment,
the leaked liquid buffer structure 122 includes two leaked liquid buffer sub-members
1221 that are spaced apart from each other. A material of the leaked liquid buffer
sub-member 1221 is a hard porous material, for example, may be a material such as
a porous ceramic or a porous metal with the supporting capability and the liquid absorbing
capability, so that the leaked liquid buffer sub-member can be served as a support
member 127 supporting the vaporization core 2. It may be understood that, if the vaporization
core 2 is fixed through another component, the leaked liquid buffer sub-member 1221
may not be configured to support the vaporization core 2. When the air pressure in
the liquid storage tank 4 is greater than the air pressure in the vaporization cavity
125, the leaked liquid buffer sub-member 1221 can collect e-liquid leaked from the
porous substrate 21. When the air pressure in the liquid storage tank 4 is less than
the air pressure in the vaporization cavity 125, the e-liquid stored in the leaked
liquid buffer sub-member 1221 can reflux to the porous substrate 21 in contact with
the leaked liquid buffer sub-member, such that the leaked e-liquid can be further
utilized effectively, and cyclic collection and reflux of the e-liquid for a plurality
of times may be achieved through the leaked liquid buffer structure 122. The liquid
absorbing capability of the porous material forming the leaked liquid buffer structure
122 is less than the liquid absorbing capability of the porous material forming the
e-liquid transmission portion 211. The condensed liquid collecting structure 14 and
the vent channel 15 are in communication with the leaked liquid buffer sub-structure
122, and liquid collected in the condensed liquid collecting structure 14 refluxes
to the porous substrate 21 in contact with the leaked liquid buffer structure through
the leaked liquid buffer structure 122.
[0106] Referring to FIG. 23, FIG. 23 is a schematic structural diagram of a second embodiment
of a leaked liquid buffer structure according to this application. In another specific
embodiment, the leaked liquid buffer structure 122 is U-shaped and the material thereof
is the hard porous material. Specifically, the leaked liquid buffer structure 122
includes the leaked liquid buffer sub-member 1221 and a connecting portion 1222 connected
to an end portion of the leaked liquid buffer sub-member 1221 away from the porous
substrate 21. Materials of the leaked liquid buffer sub-member 1221 and the connecting
portion 1222 are porous materials, for example, may be materials such as a porous
ceramic or a porous metal with the supporting capability and the liquid absorbing
capability. A duct matching the air inlet hole 126 provided on the foundation base
121 is provided on the connecting portion 1222. The connecting portion 1222 is configured
to absorb condensed e-liquid that is condensed from the vaporized e-liquid in the
vaporization cavity 125, which is defined cooperatively by the leaked liquid buffer

For example, the material of the leaked liquid buffer structure 122 may be a material
such as a porous ceramic or a porous metal with a supporting capability and a liquid

material of the leaked liquid buffer structure 122 may be alternatively a material
such as cotton, fiber, or liquid absorbing resin with a liquid absorbing capability
and without a supporting capability. The liquid absorbing capability of the porous
material forming the leaked liquid buffer structure 122 is less than the liquid absorbing

fourth embodiment of a leaked liquid buffer structure according to this application;
and FIG. 26 is a top view of the leaked liquid buffer structure provided in FIG. 25.
In a specific embodiment, the material of the leaked liquid buffer structure 122 is
a soft porous material. The anti-leakage liquid absorbing member 1227 is supported
by the support portion 127, so that an end of the leaked liquid buffer structure 122
is in contact with the porous substrate 21, and another end extends to the bottom
of the vaporization cavity 125. The support portion 127 includes a first support sub-member
1271 and a second support sub-member 1272. An airflow guide channel 1233 is provided

portion 211 in the porous substrate 21, and another end extends to the foundation
base 121 of the lower base body 12. The airflow guide channel 1233 may be a groove
structure, and a size of a groove of the airflow guide channel 1233 is greater than
a size of a first capillary groove 1223. An opening 31 of an end of the airflow guide
channel 1233 is provided on an inner side wall of each of the first support sub-member
1271 and the second support sub-member 1272, and an opening 31 of another end is located
on an end surface of the first support sub-member 1271 and the second support sub-member
1272 away from the foundation base 121, and the leaked liquid buffer structure 122
filled in the airflow guide channel 1233 is in contact with the e-liquid transmission
portion 211. A size of a cross section of a groove provided on surfaces of the first
support sub-member 1271 and the second support sub-member 1272 away from the foundation
base 121 is not less than a contact size between the e-liquid transmission portion
211 and the first support sub-member 1271 and the second support sub-member 1272.
Specifically, a width of an opening 31 of the airflow guide channel 1233 on the end
surfaces of the first support sub-member 1271 and the second support sub-member 1272
in a connecting line direction of the first support sub-member 1271 and the second
support sub-member 1272 is not less than a contact width between the first support
sub-member 1271 and the second support sub-member 1272 and the e-liquid transmission
portion 211 in the connecting line direction of the first support sub-member 1271
and the second support sub-member 1272. The leaked liquid buffer structure 122 is

to the e-liquid transmission portion 211, and another end extends between the first
support sub-member 1271 and the second support sub-member 1272, or may extend to a
surface of the foundation base 121, such that the condensed liquid of the vaporized
e-liquid may be collected, thereby preventing the vaporized e-liquid from leaking
out from the air inlet hole 126 provided on the foundation base 121 after being condensed
and preventing affecting the user experience. When the air pressure in the liquid
storage tank 4 decreases, the leaked liquid buffer structure 122 may further enable
the collected e-liquid to reflux, due to the capillary force, to the e-liquid transmission
portion 211 in contact with the leaked liquid buffer structure, such that the leaked
liquid may be utilized effectively, and the leaked liquid buffer structure 122 allows
the cyclic collection and reflux of the e-liquid for a plurality of times to be achieved.
The liquid absorbing capability of the leaked liquid buffer structure 122 is less
than the liquid absorbing capability of the e-liquid transmission portion 211. Specifically,
the liquid absorbing capability of the porous material forming the leaked liquid buffer
structure 122 is less than the liquid absorbing capability of the porous material
forming the e-liquid transmission portion 211. The leaked liquid buffer structure
122 may be made of a liquid absorbing material such as cotton, fiber, or liquid absorbing
resin. The condensed liquid collecting structure 14 and the vent channel 15 are in
communication with the leaked liquid buffer structure 122, and the liquid collected
in the condensed liquid collecting structure 14 refluxes to the porous substrate 21
in contact with the leaked liquid buffer structure through the leaked liquid buffer
structure 122.
[0110] When a temperature increases, a size of each bubble in the e-liquid in the liquid
storage tank 4 may expand to increase the air pressure in the liquid storage tank
4, and the e-liquid in the vaporization core 2 further leaks from the vaporization
core 2 through the end portions of the e-liquid transmission portion 211. The e-liquid
leaked from the e-liquid transmission portion 211 can flow to the leaked liquid buffer
structure 122 connected to the e-liquid transmission portion 211, the leaked liquid
buffer structure 122 is configured to collect the leaked e-liquid, and the e-liquid
can penetrate in an extending direction of the leaked liquid buffer structure 122,
such that the e-liquid may be prevented from leaking out from the air inlet hole 126.
When the temperature decreases, the vaporized e-liquid in the vaporization cavity
125 may form e-liquid through cooling and flows to the foundation base 121, and the
e-liquid is collected through the leaked liquid buffer structure 122 extending to
the surface of the foundation base 121. Meanwhile, the size of each bubble in the
e-liquid in the liquid storage tank 4 may shrink to decrease the air pressure in the
liquid storage tank 4. Since there is an air pressure difference between the inside
and the outside of the liquid storage tank 4, the e-liquid collected and stored in
the leaked liquid buffer structure 122 flows, along the leaked liquid buffer structure
122, to the e-liquid transmission portion 211 connected to the leaked liquid buffer
structure 122 in a direction approaching the e-liquid transmission portion 211 through
capillary action, to effectively utilize the collected e-liquid.

cavity 125 or the foundation base 121 and is in contact with the e-liquid transmission
portion 211, and another end of the body extends in a direction approaching the bottom
of the vaporization cavity 125 or the foundation base 121. The first capillary groove

1224 may be the same as the number of the first capillary grooves 1223, namely, one
first capillary groove 1223 is in communication with one corresponding second capillary
groove 1224. The first capillary groove 1223 can allow e-liquid leaked from end portions
of the e-liquid transmission portion 211 to flow to the second capillary groove 1224
in an extending direction of the first capillary groove 1223, to store the leaked

the air pressure in the liquid storage tank 4, and the e-liquid in the vaporization
core 2 further leaks from the vaporization core 2 through the end portions of the

2, may be cooled to form e-liquid and then flows to the foundation base 121, and the
e-liquid is collected by the second capillary groove 1224. Meanwhile, the size of
each bubble in the e-liquid in the liquid storage tank 4 may shrink to decrease the
air pressure in the liquid storage tank 4. Since there is an air pressure difference
between the inside and the outside of the liquid storage tank 4, the e-liquid collected
and stored in the first capillary groove 1223 and the second capillary groove 1224
flows, along the first capillary groove 1223 and due to the capillary force, to the

of the second capillary grooves 1224 may be the same as the number of the capillary
holes 1225, namely, one capillary hole 1225 is in communication with one corresponding

storage tank 4 may expand to increase the air pressure in the liquid storage tank
4, and the e-liquid in the vaporization core 2 further leaks from the vaporization

cavity 125 may form e-liquid through cooling and flows to the foundation base 121,
and the e-liquid is collected through the second capillary groove 1224. Meanwhile,
the size of each bubble in the e-liquid in the liquid storage tank 4 may shrink to

and the first air inlet hole 304 runs through the bottom wall 301. There may be two
first air inlet holes 304, a connecting line of the two first air inlet holes 304
passes through a geometric center of the bottom wall 301, and may be further parallel
to the two opposite long sides. A position where the first air inlet hole 304 is provided
matches a position where an electrode connector 306 is provided, provided that end
portions of the electrode connector 306 are exposed. The first air inlet hole 304
is configured to expose the electrode connector 306, and a size of the first air inlet
hole 304 is greater than a size of the electrode connector 306, so that a gap between
the electrode connector 306 and the first air inlet hole 304 serves as an air inlet
of an air passage of an air sensor. A shape of the first air inlet hole 304 may be
a square or may be a rectangle or a circle. The shape of the first air inlet hole
304 may be the same as or different from an image of a cross section of the electrode
connector 306. The shape and an area of the first air inlet hole 304 may be the same
as or different from those of an end surface of the air passage of the air sensor,
provided that air in the air passage of the air sensor enters the vaporizer 10, and
the shape of the first air inlet hole 304 is not limited herein.
[0123] In this embodiment, the second air inlet hole 305 is provided on the first connecting
portion 405 provided between the bottom wall 301 and the cylindrical side wall 302.
The second air inlet hole 305 communicates the inner cavity with the outside of the
end cap 30. The second air inlet hole 305 extends onto the bottom wall 301 and the
cylindrical side wall 302, so that air in a gap between the shell 201 and the side
wall of the vaporizer 10 may enter the vaporizer 10 through the second air inlet hole
305, and air in a gap between the end cap 30 and the power supply component 202 may
also enter the vaporizer 10 through the second air inlet hole 305. When the shell
201 abuts against the side wall of the vaporizer 10 excessively tightly, the air in
the gap between the end cap 30 and the power supply component 202 may enter the vaporizer
10 through the second air inlet hole 305, to ensure an air inlet amount. When the
end cap 30 abuts against the power supply component 202 excessively tightly, the air
in the gap between the shell 201 and the side wall of the vaporizer 10 may enter the
vaporizer 10 through the second air inlet hole 305, to ensure an air inlet amount.
In addition, when the vaporizer 10 is plugged and unplugged, the air in the gap between
the shell 201 and the side wall of the vaporizer 10 may complement to the gap between
the end cap 30 and the power supply component 202 through the second air inlet hole
305, to further reduce a negative pressure generated between the end cap 30 and the
power supply component 202, thereby preventing the negative pressure from affecting
an air pressure in the air passage of the air sensor and reducing a possibility of
mistaken triggering.
[0124] In this embodiment, the second air inlet hole 305 is provided on the two opposite
long sides. Therefore, a travel distance that liquid is leaked from the bottom of
the vaporization cavity 125 can be extended, and the liquid leaked from the bottom
of the vaporization cavity 125 may not directly leak out. Compared with arranging
the second air inlet hole 305 on the short sides provided opposite to each other,
arranging the second air inlet hole 305 on the two opposite long sides can reduce
an air inlet travel distance, so that air inlet can be quick and smooth and start
is more agilely in an inhalation process. In a specific embodiment, there may be one
or two or more second air inlet holes 305. In an exemplary embodiment, to ensure the
air inlet amount in the vaporizer 10, there are two second air inlet holes 305. The
two second air inlet holes 305 may be provided on one long side, and the two second
air inlet holes 305 may be alternatively symmetrically provided on the two opposite
long sides. A connecting line of the two second air inlet holes 305 passes through
the geometric center of the bottom wall 301 and is perpendicular to the two opposite
long sides. An area of the second air inlet hole 305 is from 1.0 square millimeters
to 2.0 square millimeters. In an exemplary embodiment, the area of the second air
inlet hole 305 is 1.5 square millimeters. A shape of the second air inlet hole 305
may be a square or may be a rectangle or a circle, provided that air on an outer side
of the end cap 30 can enter the inner cavity through the second air inlet hole 305,
and the shape of the second air inlet hole 305 is not limited. An air inlet source
of the second air inlet hole 305 may be air entering from a charging port of the power
supply component 202 or may be air entering from a through hole opened on the shell
201.
[0125] In an embodiment, a third air inlet is further provided on the bottom wall 301, a
third air inlet is also provided on the cylindrical side wall 302, and the third air
inlets on the bottom wall 301 and/or the cylindrical side wall 302 are in communication
with the second air inlet hole 305.
[0126] An air inlet groove 307 is provided on a bottom surface of the lower base body 12
close to the end cap 30, the end cap 30 covers the air inlet groove 307 to form an
air inlet channel 308, and the air inlet channel 308 is in communication with the
air inlet hole 126 of the vaporization cavity 125. The first air inlet hole 304 and/or
the second air inlet hole 305 provided on the end cap 30 are/is provided corresponding
to an end portion of the air inlet channel 308 away from the air inlet hole 126 and
in communication with the end portion.
[0127] In this embodiment, the first connecting portion 405 between the bottom wall 301
and the cylindrical side wall 302 is an arc surface structure, so that when the vaporizer
10 is inserted in the shell 201 and is in contact with a battery component, a gap
is always formed between the end cap 30 and the power supply component 202, thereby
ensuring smooth air inlet.
