[0042] like Figures 1 to 4 FIG. 1 shows an electronic cigarette according to an embodiment of the present invention, comprising an air intake structure 100 . The electronic cigarette further comprises a housing 200 , a liquid reservoir 300 , a battery assembly 400 , and a circuit board 500 . The liquid reservoir 300 , the battery assembly 400 , and the circuit board 500 are all disposed inside the housing 200 . A nozzle 600 is disposed at the top of the housing 200 . An atomizer core 310 is disposed inside the liquid reservoir 300 . The atomizer core 310 is electrically connected to the circuit board 500 , and the battery assembly 400 is electrically connected to the circuit board 500 .

[0043] Specifically, the air intake structure 100 is arranged below the oil storage cotton 300, and the upper end of the air intake structure 100 is connected to the inner side of the oil storage cotton 300; a through hole 210 is provided at the bottom of the outer shell 200, and the lower end of the air intake structure 100 is connected to the through hole 210; the battery assembly 400 is assembled in the air intake structure 100, and the circuit board 500 is arranged on one side of the air intake mechanism.

[0044] During use, the user draws air through the nozzle 600, and external air enters the electronic cigarette through the perforation 210, and the air enters the oil storage cotton 300 through the air intake structure 100; the atomization core 310 generates high temperature to atomize the oil in the oil storage cotton 300 into smoke, and the smoke is inhaled by the user through the nozzle 600 under the action of the airflow.

[0045] like Figures 5 to 9 As shown, the air intake structure 100 is used to connect the outside world with the electronic cigarette to prevent condensation from affecting components.

[0046] See also Figure 6 and Figure 7 The air intake structure 100 includes a bracket 11, an upper connecting seat 12 mounted on the upper end of the bracket 11, and a lower connecting seat 13 mounted on the lower end of the bracket. The bracket 11 is provided with a channel 111, which vertically passes through the bracket 11. The upper end of the bracket 11 is provided with an air outlet groove 112 connected to the channel 111, and the lower end of the bracket 11 is provided with an air intake groove 113 connected to the channel 111. The air outlet groove 112, the channel 111, and the air intake groove 113 form a gas channel 115, through which external air enters the electronic cigarette. A accommodating chamber 114 is provided in the middle of the bracket 11, and the accommodating chamber 114 and the gas channel 115 are not connected to each other.

[0047] When in use, external air enters the gas channel 115 through the perforation 210; the external air flows along Figure 9 and Figure 10 The airflow in the oil storage sponge passes sequentially through the air inlet slot 113, the hole 111, and the air outlet slot 112, ultimately entering the oil storage sponge 300. After use, the temperature drops, and condensation forms on the inner wall of the air channel 115. The battery assembly 400 is located in the accommodating cavity 114, and the circuit board 500 is located on one side of the bracket 11. The air channel 115 does not contact the battery assembly 400, the circuit board 500, and other components, so the condensation does not come into contact with the components and cause negative effects such as corrosion or short circuits.

[0048] Specifically, the upper connecting seat 12 is arranged around the outer edge of the air outlet groove 112, and the upper connecting seat 12 and the air outlet groove 112 form a first cavity 123 therebetween. The upper connecting seat 12 is provided with an air outlet hole 121, which is connected to the air outlet groove 112. A plug-in column 122 extends from the upper end of the upper connecting seat 12, and the air outlet hole 121 vertically passes through the plug-in column 122. After assembly is completed, the plug-in column 122 is plugged into the oil storage cotton 300. The upper connecting seat 12 is provided, and the bracket 11 is connected to the oil storage cotton 300 through the upper connecting seat 12. During use, the airflow enters the first cavity 123 along the gas channel 115, and enters the oil storage cotton 300 through the air outlet hole 121 in the plug-in column 122. The first cavity 123 acts as a buffer, and the airflow enters the oil storage cotton 300 through the air outlet hole 121. The airflow is more concentrated, thereby improving the user experience of smoking.

[0049] Specifically, an oil-absorbing cotton pad 124 is provided on the inner side of the outlet groove 112. The oil-absorbing cotton pad 124 is used to absorb condensed liquid from the outlet groove 112, further preventing the condensed liquid from coming into contact with the components. Furthermore, a stopper 126 is provided on the inner side of the outlet groove 112. The stopper 126 is used to limit the position of the oil-absorbing cotton pad 124. The oil-absorbing cotton pad 124 is fixed between the stopper 126 and the inner wall of the outlet groove 112 to prevent it from falling out. The oil-absorbing cotton pad 124 is provided with an air-avoidance gap 125. The air-avoidance gap 125 is arranged corresponding to the channel 111 to prevent the oil-absorbing cotton pad 124 from clogging the channel 111 and affecting the air flow into the outlet groove 112.

[0050] Specifically, the lower connecting seat 13 is arranged around the outer edge of the air inlet groove 113, and a second cavity 131 is formed between the lower connecting seat 13 and the air inlet groove 113. The lower connecting seat 13 is provided with an air inlet hole 132, and the air inlet hole 132 is connected to the air inlet groove 113; the lower connecting seat 13 is used to realize the connection between the bracket 11 and the shell 200; the external gas enters the second cavity 131 through the air inlet hole 132, and enters the electronic cigarette through the gas channel 115.

[0051] More specifically, a movable air-blocking block 133 is provided at the lower end of the lower connecting base 13. This block 133 is locked within the air inlet 132. The block 133 can slide along the length of the air inlet 132 to adjust the area of ​​the air inlet 132 it blocks. The user can adjust the area of ​​the air inlet 132 it blocks by manipulating the block 133, thereby adjusting the air intake volume of the electronic cigarette and ultimately producing varying amounts of vapor.

[0052] Specifically, the bracket 11 is provided with a mounting slot 116 extending horizontally. A through-hole 117 is provided at the bottom of the mounting slot 116, connecting the mounting slot 116 to the channel 111 through the through-hole 117. Correspondingly, a microphone switch 510 for sensing airflow is welded to the circuit board 500. The circuit board 500 controls the start or stop of the atomizer core 310 based on the airflow sensed by the microphone switch 510. When the circuit board 500 is assembled to one side of the bracket 11, the microphone switch 510 is assembled into the mounting slot 116. The sensing end of the microphone switch 510 senses the airflow within the channel 111 through the through-hole 117. After assembly, the microphone switch 510 blocks the through-hole 117, ensuring airflow sensing while preventing condensation from contacting the circuit board 500 through the through-hole 117.

[0053] Furthermore, a positioning member 118 is fixedly provided inside the mounting groove 116 , and a through hole communicating with the through hole 117 is provided at the bottom of the positioning member 118 , and the microphone switch 510 is assembled to the inside of the positioning member 118 to improve assembly stability.

[0054] Compared with the prior art, the air intake structure 100 and the electronic cigarette involved in the present invention include a bracket 11, on which an air intake groove 113, a channel 111 and an air outlet groove 112 are provided, forming a sealed gas channel 115; a receiving chamber 114 for accommodating the battery assembly 400 is also provided on the bracket 11, and the receiving chamber 114 and the gas channel 115 are not connected to each other; during the use of the electronic cigarette, external gas enters the electronic cigarette through the gas channel 115, and the condensate generated in this process will not come into contact with components such as the circuit board 500 and the battery assembly 400, thereby avoiding affecting the components; at the same time, the microphone switch 510 of the circuit board 500 is connected to the gas channel 115, thereby ensuring the normal use of the electronic cigarette under the premise of avoiding the influence of condensate; in addition, oil-absorbing cotton 124 is provided in the air intake groove 113 to further absorb condensate to ensure the normal use of the electronic cigarette.

[0055] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
