Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a ring-shaped induction airway microphone sealing structure for preventing oil immersion used in electronic cigarettes. Background Art

[0002] Electronic cigarettes typically feature an airflow sensor to detect the airflow generated when a user inhales. When the microphone sensor (also known as an airflow sensor) senses the airflow, it sends a signal to the main control chip, informing it that the user is inhaling, thereby activating the electronic cigarette. Existing microphone sensors typically have an airflow sensing hole located at the top, which can easily allow smoke oil and condensate to enter the sensor, causing damage and loss of function. Therefore, it is necessary to optimize the design of the airway structure for the microphone sensor, both for airflow entry and for the discharge of the smoke oil and condensate mixture. This ensures that the microphone sensor is protected from oil contamination by the mixture while still allowing it to drain. Utility Model Content

[0003] In order to achieve the above-mentioned purpose, the utility model proposes an electronic cigarette with a ring-shaped induction airway microphone sealing structure that prevents oil immersion.

[0004] The present invention discloses an electronic cigarette with an annular inductive airway microphone sealing structure that prevents oil immersion, comprising a cartridge unit and a battery main unit. The battery main unit has an upper end with a plug-in cavity, into which the cartridge unit is plugged and electrically connected to the battery main unit. The battery main unit comprises a main housing and a mounting bracket sleeved within the main housing. The mounting bracket has an upper end with an upper base, and the sides and lower ends of the upper base are bracket frames. The bracket frames are provided within the bracket frames. A battery and a main control circuit board are provided within the bracket frames. A first electrode terminal group is provided in the middle of the upper base. A microphone mounting position for mounting a microphone sensor is provided at one side of the bottom of the upper base. An air inlet channel is provided on the bracket frame on the other side of the microphone mounting position. The air inlet channel communicates with the top surface of the upper base. A first annular groove is provided around the outer wall of the upper base. A first channel opening communicating with the microphone mounting cavity and a second channel opening communicating with the air inlet channel are provided on either side of the first annular groove. The air inlet channel communicates with an air inlet hole provided on the side wall of the main housing.

[0005] Furthermore, a first silicone seal is provided on the first annular groove, and the outer wall of the first silicone seal is a second annular groove provided on the first annular groove. The bottom of the second annular groove is provided with through holes corresponding to the positions of the first channel opening and the second channel opening. The first silicone seal is used to form a seal with the inner wall of the main housing.

[0006] Furthermore, the first silicone seal is provided with an air intake channel edge sealing silicone ring integrally formed with the first silicone seal on one side of the air intake channel on the bracket frame, which is used to form a seal between the edge of the air intake channel and the inner wall of the host shell.

[0007] Furthermore, the microphone mounting position is integrally injection molded with the mounting bracket, the top of the microphone mounting position is an opening, a second silicone seal is embedded in the opening, the second silicone seal is in the shape of a cover plate, and a groove extending from the middle to the edge is provided at the bottom of the second silicone seal, and the notch formed at the edge of the second silicone seal docks with the first channel opening.

[0008] Furthermore, an air regulating valve that moves up and down is provided at the air intake passage in the air intake hole, and the air regulating valve adjusts the size of the air intake hole by moving its position.

[0009] Furthermore, the cigarette cartridge unit adopts a double heating wire atomizer core, and a second electrode terminal group connected to the double heating wire atomizer core is provided at the bottom of the cigarette cartridge unit, and the second electrode terminal group is electrically connected to the first electrode terminal group in a contact manner.

[0010] Furthermore, the main control circuit board is connected to a control key panel for controlling single heating or dual heating of the dual heating wire atomizer core. The control key panel is fixed to any side of the bracket frame of the mounting bracket, and the side wall of the host shell corresponding to the side where the control key panel is provided is provided with a hole for exposing the key cap installed on the control key panel.

[0011] Furthermore, the main control circuit board is connected to a display screen for displaying the power level and the single heating or dual heating working mode of the dual heating wire atomizer core.

[0012] Furthermore, the main control circuit board is connected to a charging board, which is provided with a charging socket. The charging board is fixed to the lower end of the mounting bracket, and a hole is provided at the bottom of the host housing to expose the charging socket.

[0013] The beneficial effects of the present invention are as follows: The core design innovation of the electronic cigarette designed according to this technical solution lies in the design of the microphone mounting position of the microphone sensor of the battery host unit and the airway for activating the microphone sensor, as well as the structural design of the air intake channel and the airway for activating the microphone sensor. This ensures that the top of the microphone sensor is free of a through-hole for the inhaled airflow to form a microphone sensor sense, thereby effectively preventing the flow of smoke oil, condensate, or a mixture of the two into the microphone sensor. This solution helps to increase the service life of the microphone sensor and reduce the failure rate. In addition, the design of the air intake channel of the mounting bracket allows the smoke oil, condensate, or a mixture of the two produced by the cigarette cartridge unit at the insertion cavity of the mounting bracket, i.e., the upper end of the mounting bracket, to flow into the air intake channel and then be discharged through the air intake hole of the main body housing. When discharging the smoke oil, condensate, or mixture, the user usually wipes it with a paper towel or absorbs it through the air intake hole, which is simple and convenient, and helps to prevent the electronic cigarette from being contaminated by smoke oil, condensate, or a mixture of the two.

[0022] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts are also within the scope of protection of the present disclosure.

[0023] Please refer to Figures 1 to 5 , an electronic cigarette with an annular induction airway microphone sealing structure that prevents oil immersion provided by the present technical solution, includes a cigarette cartridge unit 1 and a battery 23 main unit 2. The upper end of the battery 23 main unit 2 is a plug-in cavity, and the cigarette cartridge unit 1 is plugged into the plug-in cavity and electrically connected to the battery 23 main unit 2. The battery 23 host unit 2 includes a host shell 21 and a mounting bracket 22 mounted in the host shell 21. The upper end of the mounting bracket 22 is an upper end seat body, and the two sides and the lower end of the upper end seat body are bracket frames. The battery 23 and the main control circuit board 24 are arranged in the bracket frame. The middle part of the upper end seat body is provided with a first electrode terminal group. The bottom of the upper end seat body is provided with a microphone mounting position 224 for mounting a microphone sensor at one side. The bracket frame on the other side opposite to the microphone mounting position 224 is provided with an air intake channel 225. The air intake channel 225 is connected to the top surface of the upper end seat body. The outer wall of the upper end seat body is provided with a first annular groove 221. The two sides of the first annular groove 221 are respectively provided with a first channel opening 223 connected to the microphone mounting cavity and a second channel opening 222 connected to the air intake channel 225. The air intake channel 225 corresponds to the air intake hole 211 provided on the side wall of the host shell 21.

[0024] Reference Figure 1 、 Figure 2 , further, a first silicone seal 28 is sleeved on the first annular groove 221, and the outer wall of the first silicone seal 28 is a second annular groove 281 sleeved on the first annular groove 221, and the bottom of the second annular groove 281 is corresponding to the positions of the first channel opening 223 and the second channel opening 222, and a through hole 282 is correspondingly provided. The first silicone seal 28 is used to form a seal with the inner wall of the main housing 21 to prevent the first annular groove 221 on the outer wall of the upper end seat of the mounting bracket 22 from having a gap with the inner wall of the main housing 21. The gap will cause the smoke oil or condensate or a mixture of the two in the cartridge unit 1 to flow into the gap, causing damage to the battery 23 inside the main unit 2.

[0025] Furthermore, the first silicone seal 28 is provided with an air intake channel edge sealing silicone ring 283 integrally formed with the first silicone seal 28 on one side of the air intake channel 225 corresponding to the frame of the bracket, which is used to form a seal between the edge of the air intake channel 225 and the inner wall of the main body shell 21 to prevent a gap between the edge of the air intake channel 225 and the inner wall of the main body shell 21, which will cause air leakage in the air intake channel 225 and affect the suction resistance sensing of the microphone sensor.

[0026] Please refer to Figures 2 to 5 Furthermore, the microphone mounting position 224 is integrally injection molded with the mounting bracket 22. The top of the microphone mounting position 224 is open, and a second silicone sealant 25 is embedded in the opening. The second silicone sealant 25 is in the form of a cover plate, and a groove 251 is formed at the bottom of the second silicone sealant 25, extending from the center to the edge. The groove formed at the edge of the second silicone sealant 25 engages with the first channel opening 223. Integrated injection molding improves component production efficiency, but an opening is required at the top of the microphone mounting position 224 to facilitate the insertion of the microphone sensor. The second silicone sealant 25 is then designed to serve as a cover plate to cover the opening, and a groove 251 is formed at the bottom of the second silicone sealant 25. The groove 251 engages with the first channel opening 223. This design eliminates the need for a top opening for the microphone sensor, unlike conventional microphone mounting positions 224, which have a top opening for sensing airflow. Conventional designs can easily cause smoke oil, condensate, or a mixture of the two to enter the microphone sensor, causing damage.

[0027] Please refer to, Figure 6 When the electronic cigarette designed in this solution is used for inhalation, external air enters through the air inlet channel 225. Since the air inlet channel 225 is connected to the second channel opening 222, the second channel opening 222 and the first channel opening 223 connected to the microphone mounting position 224 form an annular first annular groove 221. In order to seal the annular groove and the inner wall of the main body shell 21, a first silicone seal 28 is provided on the first annular groove 221. Through the second annular groove 281 on the first silicone seal 28 and the through-hole opening 282 corresponding to the first channel opening 223 and the second channel opening 222, the airflow of the microphone sensor is realized to flow in the second annular groove 281, thereby effectively preventing the microphone sensor from being immersed in smoke oil or condensate or a mixture of the two, thereby effectively protecting the microphone sensor.

[0028] Preferably, an air regulating valve 212 that moves up and down is provided at the air inlet channel 225 in the air inlet hole 211 , and the air regulating valve 212 adjusts the size of the air inlet hole 211 by moving its position.

[0029] Preferably, the cartridge unit 1 adopts a dual-heating wire atomizer core, and a second electrode terminal group connected to the dual-heating wire atomizer core is provided at the bottom of the cartridge unit 1, and the second electrode terminal group is electrically connected to the first electrode terminal group in a contact manner. The main control circuit board 24 is connected to a control key panel 26 for controlling single heating or dual heating of the dual-heating wire atomizer core. The control key panel 26 is fixed to any side of the bracket frame of the mounting bracket 22, and the side wall of the main housing 21 corresponding to the side where the control key panel 26 is provided is provided with a hole for exposing the key cap installed on the control key panel 26. The main control circuit board 24 is connected to a display screen 27 for displaying the power level and the single heating or dual heating working mode of the dual-heating wire atomizer core.

[0030] Preferably, the main control circuit board 24 is connected to a charging board 29, which is provided with a charging socket. The charging board 29 is fixed to the lower end of the mounting bracket 22, and a hole is provided at the bottom of the host housing 21 to expose the charging socket.
