DETAILED DESCRIPTION

[0024] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] This application proposes a gas-controllable electronic cigarette, please refer to Figure 1 、 Figure 3 and Figure 4, including: a mouthpiece 10, an atomizer assembly 11, a control assembly 12, a seal 20 and a shell 30. The shell 30 is hollow and has an accommodating cavity inside. The atomizer assembly 11, the control assembly 12 and the seal 20 are all arranged in the accommodating cavity. The atomizer assembly 11 and the control assembly 12 are electrically connected. The shell 30 includes a top, an upper part, a lower part and a bottom part. The control assembly 12 is arranged at the lower part, the atomizer assembly 11 is arranged at the upper part, the mouthpiece 10 is arranged at the top, and the control assembly 12 is heavier. Therefore, the center of gravity is at the lower part, which makes it easier for users to hold the electronic cigarette. The atomizer assembly 11 is used to atomize the tobacco oil or heat the tobacco cartridge. The control assembly 12 can control the atomizer assembly 11 to be in working state or standby state. When the user draws at the mouthpiece 10, the control assembly 12 sends a working instruction to the atomizer assembly 11, and the atomizer assembly 11 executes the instruction work, and the rest are in standby state or off state. An air inlet 31 is provided on the housing 30, and an air flow channel 33 is provided at the connection gap between the atomizer assembly 11 and the control assembly 12. The seal 20 is provided below the air flow channel 33, and an extension 23 extends from the top of the seal 20. The extension 23 seals against the air inlet end of the atomizer assembly 11, sealing the air inlet end of the atomizer assembly 11. The seal 20 is provided with a vent 21 in communication with the atomizer assembly 11, so that the gas of the atomizer assembly 11 can only enter through the vent 21. That is, the gas that enters the air flow channel 33 due to part tolerances and assembly errors also enters the interior of the atomizer assembly 11 through the vent 21. The air inlet 31, air flow channel 33, vent 21, atomizer assembly 11, and mouthpiece 10 are sequentially connected to prevent air leakage caused by component tolerances and assembly errors from affecting the draw resistance. The size of the vent 21 stabilizes the draw resistance of the electronic cigarette. Compared with the prior art, the draw resistance of the electronic cigarette is controlled by the air inlet, and the size of the air inlet determines the air intake rate. However, due to problems such as component assembly and manufacturing tolerances, air leaks exist in various places in the electronic cigarette, resulting in poor sealing. However, the separate vent in this application solves the problem of insensitive draw of the electronic cigarette. Without increasing product costs, the user experience is improved.

[0026] It should be noted that when the electronic cigarette is in working state: when the user draws air at the mouthpiece 10, the external gas flows through the air inlet 31, the air flow channel 33 and the vent 21 in sequence, and all the external gas enters the atomizer assembly 11 through the vent 21. The atomizer assembly 11 heats the cigarette cartridge to form smoke, and finally the smoke is drawn out from the mouthpiece 10.

[0027] See also Figure 1 There are two air inlet holes 31, which are symmetrically arranged so that external air can quickly enter the air flow channel 33, reducing the resistance of the user to inhale the electronic cigarette.

[0028] Further, see Figure 2 and Figure 3The seal 20 is made of silicone. During assembly, first install the seal 20, then press the atomizer assembly 11 down to the top of the seal 20, where it seals against the top of the seal 20, enhancing the seal and further improving the stability of the draw resistance. In addition, the top of the seal 20 is a right or inverted frustum, with a hollow interior. The top of the seal 20 seals the air inlet end of the atomizer assembly 11, ensuring a tight seal.

[0029] Furthermore, the controllable gas electronic cigarette also includes a reinforcement frame 22, which is sleeved in the vent 21. The reinforcement frame 22 is made of hard plastic to stabilize the shape of the vent 21, prevent the vent 21 from being squeezed and deformed, and cause changes in the inhalation resistance, thereby improving the stability of the controllable gas electronic cigarette.

[0030] In one embodiment, the atomizer assembly 11 includes a heating coil, a smoke channel, and a cartridge slot. The cartridge slot is used to hold a cigarette cartridge, and the heating coil abuts against the cigarette cartridge in the cartridge slot. When the atomizer assembly 11 is in operation, the heating coil is energized and generates heat, which is used to heat the cigarette cartridge. External gas enters through the smoke channel, and the partially vaporized cigarette cartridge mixes with the external gas to produce smoke. The smoke flows through the smoke channel and is ultimately drawn out of the mouthpiece 10.

[0031] Further, see Figure 1 The control component 12 includes a battery cell 121 and a circuit board 122. The battery cell 121 is electrically connected to the circuit board 122 and the atomizer assembly 11 respectively. The battery cell 121 is used to power the circuit board 122 and the atomizer assembly 11, ensuring that the electronic cigarette can be used in any scenario without the need for an external power supply, making it easy to carry and use. In addition, the control component 12 is also equipped with a switch. The switch is electrically connected to the circuit board 122 and can control the on and off of the battery cell 121 supplying energy to the atomizer assembly 11, so that the electronic cigarette can be turned off, saving energy and avoiding accidental touches.

[0032] In one embodiment, please continue to refer to Figure 4 The housing 30 is provided with a charging port 32 at its bottom. The charging port 32 is electrically connected to the battery cell 121 and is electrically connected to an external power source via a charger. The charging port 32 can charge the battery cell 121, thus enabling recycling of the battery cell 121. Furthermore, the charging port 32 is electrically connected to the control assembly 12. The charging port 32 snaps onto the circuit board 122, facilitating assembly and maintenance. Preferably, the top of the housing 30 is flat, suitable for contact between the top mouthpiece 10 and the lips, making the inhalation feel pleasant to the user.

[0033] Furthermore, a sealing ring is provided in the fitting gap between the atomizing assembly 11 and the housing 30 below the smoke passage to prevent smoke from escaping from the fitting gap or air from entering the smoke passage therefrom, thereby affecting the suction effect and taste.

[0034] Also, please refer again to Figure 1 Two positioning posts 40 extend from the housing 30 toward the circuit board 122. Two positioning holes are defined in the circuit board 122. The top ends of the positioning posts 40 penetrate into the holes, and the middle portions of the positioning posts 40 abut against the edges of the holes. This allows the circuit board 122 to be precisely positioned before being screwed in. The housing 30 has two screw holes, and the circuit board 122 has matching fixing holes. Screws pass through the fixing holes and engage with the screws, with the nuts abutting against the circuit board 122, making it easier for assemblers to secure the circuit board 122 to the housing 30 with screws.

[0035] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
