CA 3194259 2023-03-28
[0033] Referring to FIGS. 1-2, the electronic cigarette atomizer includes a
housing body
100, a cigarette holder 300, and a base 200. The cigarette holder 300 and the
base 200 are
respectively disposed on the housing body 100.
[0034] Furthermore, a battery bin 110 and a cigarette cartridge bin 120 are
disposed in
the housing body 100. A battery 130 is detachably disposed in the battery bin
110. A first
opening 150 is defined in a first end of the housing body 100. The first
opening 150 is
communicated with the battery bin 110 and the cigarette cartridge bin 120. A
second
opening 160 is defined in a second end of the housing body 100. The second
opening 160
is communicated with the cigarette cartridge bin 120.
[0035] The embodiment further provides two first openings 150, one of the two
first
openings 150 is communicated with the battery bin 110, the other one of the
two first
openings 150 is communicated with the cigarette cartridge bin 120, and sizes
and shapes
of the two first openings 150 are inconsistent.
[0036] Of course, in some embodiments, one first opening 150 is provided, and
the first
opening 150 is simultaneously communicated with the cigarette cartridge bin
120 and the
battery bin 110.
[0037] The cigarette holder 300 is disposed at one end, close to the second
opening 160,
of the housing body 100. When the cigarette holder 300 is disposed on the
housing body
100, a channel in the cigarette holder 300 is communicated with the second
opening 160.
[0038] The cigarette holder 300 and the housing body 100 are connected through
buckles.
[0039] A PCB (Printed Circuit Board) 210 is disposed in the base 200. An
ejector pin 220
is disposed on the PCB 210. The ejector pin 220 protrudes out of the base 200.
In addition,
a mounting hole 230 is defined on the base 200. A cigarette cartridge 140 is
detachably
mounted in the mounting hole 230. An air inlet hole 240 is further defined on
the base 200.
The air inlet hole 240 is communicated with the mounting hole 230.
[0040] The mounting hole 230 is a threaded through hole, and the cigarette
cartridge 140
6
CA 3194259 2023-03-28
is detachably connected to the mounting hole 230 in a threaded connection
mode.
[0041] Specifically, when the cigarette cartridge 140 is disposed in the
mounting hole 230,
the cigarette cartridge 140 is in contact with the PCB 210, and the PCB 210
controls
opening or closing of the cigarette cartridge 140.
[0042] When the base 200 is disposed at one end, close to the first opening
150, of the
housing body 100, the ejector pin 220 is just in contact with the battery 130
in the battery
bin 110, and the cigarette cartridge 140 is just located in the cigarette
cartridge bin 120.
[0043] During actual use, first detaching the base 200 from the housing body
100, and
then connecting an air inlet end of the cigarette cartridge 140 to the
mounting hole 230, so
that the cigarette cartridge 140 is fixed on the base 200 and is in contact
with the PCB 210.
The cigarette cartridge 140 is in contact with the PCB 210 through
conventional means,
such as through positive and negative elastic needles, which is not described
in details
herein. Then, extending the cigarette cartridge 140 into the cigarette
cartridge bin 120 in
the housing body 100, and the base 200 is connected to the housing body 100 to
complete
.. installation or replacement of the cigarette cartridge 140.
[0044] When a user inhales, external airflow sequentially enters the cigarette
cartridge
140 through the air inlet hole 240 and the mounting hole 230, and smoke
generated in the
cigarette cartridge 140 is sucked by the user along with the airflow through
the second
opening 160 and the cigarette holder 300.
[0045] According to the electronic cigarette atomizer, the base 200 and the
housing body
100 are detachably disposed, and the mounting hole 230 is defined on the base
200 to
detachably mount the cigarette cartridge 140, so as to fix the cigarette
cartridge 140. The
cigarette cartridge bin 120 is disposed in the housing body 100 to contain the
cigarette
cartridge 140, so as to hidden and protect the cigarette cartridge 140.
Therefore, according
to above mode, the cigarette cartridge 140 is fixed through the base 200, and
the cigarette
cartridge 140 is protected through the housing body 100, so that the cigarette
cartridge 140
7
CA 3194259 2023-03-28
=
is conveniently replaced and is further prevented from falling off.
[0046] Furthermore, a detachable connection between the housing body 100 and
the base
200 is specifically achieved by providing a magnet on the housing body 100
and/or the
base 200, where the magnet is not shown in the figures. The base 200 is
detachably
connected to the housing body 100 through the magnet, so that the base 200 is
more
convenient to disassemble.
[0047] Of course, in other embodiments, the base 200 and the housing body 100
are
further detachably connected through threads or buckles.
[0048] Referring to FIG. 2, a cavity is defined in the base 200, and the
cavity is
respectively communicated with the air inlet hole 240 and the mounting hole
230.
[0049] It can be understood that an interior of the base 200 is made into a
cavity structure,
on one hand, the PCB 210 is convenient to accommodate, on the other hand, the
air inlet
hole 240 is convenient to communicate with the mounting hole 230, and an air
channel
does not need to be additionally disposed. The air inlet hole 240 and the
mounting hole 230
are connected only through a structure such as the gap between the PCB 210 and
an inner
wall of the base 200, which makes structure of the whole base 200 simpler.
[0050] Furthermore, the electronic cigarette atomizer further includes a
microphone 250.
The microphone 250 is disposed in the cavity. The microphone 250 is
electrically
connected to the PCB 210. The microphone 250 is configured to sense airflow
entering the
air inlet hole 240.
[0051] When the user sucks, the external airflow enters the cavity through the
air inlet
hole 240, and after the microphone 250 senses the airflow, the PCB 210
controls the
cigarette cartridge 140 to work.
[0052] Furthermore, a mounting groove 260 is defined in the cavity of the base
200. The
microphone 250 is disposed in the mounting groove 260. An air outlet hole 270
is defined
on the base 200. The air outlet hole 270 is communicated with the mounting
groove 260.
8
CA 3194259 2023-03-28
When the base 200 is disposed on the housing body 100, the air outlet hole 270
is
communicated with the first opening 150 with respect to the cigarette
cartridge bin 120.
[0053] Specifically, a part of the airflow entering from the air inlet hole
240 is discharged
out of the base 200 from the air outlet hole 270 after passing through the
microphone 250
and enters the first opening 150, and other airflow enters the cigarette
cartridge 140 through
the mounting hole 230.
[0054] In addition, when the cigarette cartridge 140 is located in the cavity
of the cigarette
cartridge 140, a gap 170 is reserved between a side wall of the cigarette
cartridge 140 and
an inner wall of the cigarette cartridge bin 120. The gap 170 is communicated
with the first
opening 150 and the second opening 160.
[0055] Specifically, the part of the airflow entering the air inlet hole 240
is discharged out
of the base 200 from the air outlet hole 270 after passing through the
microphone 250 and
enters the gap 170 through the first opening 150, and then the part of the
airflow is
discharged through the second opening 160. The other airflow enters the
cigarette cartridge
140 through the mounting hole 230. Smoke generated in the cigarette cartridge
140 is
discharged through the second opening 160. Size and structure of the gap 170
are not
limited herein, and the gap 170 only needs to Meet requirements that the
airflow can pass
through.
[0056] It can be seen that, in the mode, the gap 170 is defined between the
cigarette
cartridge 140 and the inner wall of the cigarette cartridge bin 120 to enable
the airflow to
pass through, so that atomizing airflow 400 passing through the cigarette
cartridge 140 and
switch airflow 500 passing through the microphone 250 respectively flow out
from two
independent airflow channels. According to the mode, after the air channel in
the cigarette
cartridge 140 is blocked by the tobacco tar, the switch airflow 500 of the
microphone 250
still flows out from the channel of the switch airflow 500 generated by the
gap 170, so that
the microphone 250 further senses the airflow, and then the PCB 210 still
controls the
9
CA 3194259 2023-03-28
cigarette cartridge 140 to work to atomize the tobacco tar to open the blocked
channel. In
other words, the mode well ensures that the cigarette cartridge 140 cannot be
blocked by
the tobacco tar, and the atomizer will not stop working after the air channel
in the cigarette
cartridge 140 is blocked by the tobacco tar.
[0057] Furthermore, in order to enable the airflow discharged by the air
outlet hole 270
to enter the gap 170 and guarantee smoothness of the switch airflow 500. An
extending
portion opening 180 is further extended to one side of a position, with
respect to the
cigarette cartridge bin 120, of the first opening 150. The extending portion
opening 180 is
communicated with the cigarette cartridge bin 120.
[0058] Specifically, when the base 200 is disposed on the housing body 100,
the air outlet
hole 270 is communicated with the extending portion opening 180, and the
airflow
exhausted by the air outlet hole 270 enters the gap 170 through the extending
portion
opening 180.
[0059] Referring to FIG. 2, the housing body 100 includes a support 190a and a
housing
190b. The battery bin 110 and the cigarette cartridge bin 120 are respectively
disposed on
the support 190a. The housing 190b is sleeved on the support 190a, and the
housing 190b
is configured to surround the support 190a.
[0060] According to the above mode, the housing body 100 is divided into the
independent support 190a and the independent housing 190b, on one hand,
processing of
structures such as the battery bin 110, a cabin of the cigarette cartridge
140, the first
opening 150, and the second opening 160 are facilitated, and on the other
hand, integrity
of the housing body 100 with the cigarette holder 300 and the base 200 after
installation is
guaranteed.
[0061] Furthermore, the cigarette cartridge bin 120 and/or the battery bin 110
are
disposed as semi-surrounding structures. On one hand, the semi-surrounding
structures
facilitate formation of the gap 170, and on the other hand, the semi-
surrounding structures
CA 3194259 2023-03-28
facilitate installation of the battery 130. Meanwhile, the semi-surrounding
structures enable
the battery bin 110 and the cigarette cartridge bin 120 to be compatible with
the batteries
130 or the cigarette cartridges 140 of different sizes and models.
[0062] Referring to FIG. 2, a sealing ring 280 is disposed on an outer wall of
the base
.. 200. When the base 200 is disposed on the housing body 100, the sealing
ring 280 is located
between the outer wall of the base 200 and an inner wall of the housing 190b,
which plays
a role in sealing a joint of the base 200 and the housing body 100, prevents
oil leakage and
prevents water or other impurities from entering the cavity. And the sealing
ring 280 is
located between the outer wall of the base 200 and the inner wall of the
housing 190b,
which plays a role in horizontally extruding the sealing ring 280, and
improves sealing
effects.
[0063] Referring to FIG. 2, a charging port 290a and/or a key 290b are further
disposed
on the base 200. The charging port 290a and/or the key 290b are respectively
electrically
connected to the PCB 210. The charging port 290a is configured to charge the
battery 130,
and the key 290b is configured to control the PCB 210.
[0064] Furthermore, the air inlet hole 240 is defined between an outer wall of
the charging
port 290a and/or the key 290b and the base 200.
[0065] That is, a gap is defined between the outer wall of the charging port
290a and/or
the key 290b and the base 200, and the gap serves as the air inlet hole 240.
According to
.. the structure, a through hole does not need to be additionally defined on
the base 200 to
serve as the air inlet hole 240, which achieves a function of hiding the air
inlet hole 240.
[0066] The above descriptions are merely preferred embodiments of the present
disclosure, and are not intended to limit the present disclosure. Any
modification,
equivalent replacement, improvement and the like made within spirit and
principle of the
present disclosure shall fall within a scope of protection of the present
disclosure.
