DETAILED DESCRIPTION

[0040] The embodiments of the present application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The electronic cigarette 1 according to the embodiments of the present application is described below with reference to Figures 1 to 10. The electronic cigarette 1 includes: a shell 10 and an atomizer assembly 20, a battery assembly 30, and a circuit board 40 arranged in the shell 10.

[0041] As shown in Figures 1 to 9, the atomizer assembly 20 and the battery assembly 30 are located on the same side of the circuit board 40. The side of the circuit board 40 facing the battery assembly 30 is provided with a battery connection end 41 and an atomizer assembly connection end 42. The battery connection end 41 is electrically connected to the battery assembly 30, and the atomizer assembly connection end 42 is electrically connected to the atomizer assembly 20.

[0042] For example, the shell 10 is provided with an air inlet 121 and an air inlet 111, and an oil storage tank 13 is provided in the shell 10, and the oil storage tank 13 is used to accommodate the medium to be atomized. The atomizer assembly 20 is provided in the shell 10, and the atomizer assembly 20 is respectively connected to the air inlet 111 and the air inlet 121. The atomizer assembly 20 includes an atomizer core 21, and the atomizer core 21 is used to atomize the medium to be atomized to release an aerosol. The battery assembly 30 is provided on the side of the atomizer assembly 20 away from the air inlet 111, and the battery assembly 30 and the atomizer assembly 20 are both electrically connected to the circuit board 40. To facilitate electrical connection with the circuit board 40, a battery connection terminal 41 and an atomizer assembly connection terminal 42 are provided on the circuit board 40. The battery assembly 30 supplies power to the circuit board 40, and the circuit board 40 is electrically connected to the atomizer assembly 20 so that the atomizer assembly 20 can work.

[0043] According to the electronic cigarette 1 of the embodiment of the present application, by locating the battery connection terminal 41 and the atomizer assembly connection terminal 42 provided on the circuit board 40 on the same side, the connection between the circuit board 40 and the battery assembly 30 and the atomizer assembly 20, as well as the installation and positioning of the circuit board 40 and the battery assembly 30 are facilitated, so that the internal structure of the electronic cigarette 1 can be modularly designed, the assembly efficiency is improved, the design of the wiring harness is reduced, the internal space of the electronic cigarette 1 is saved, the assembly process is reduced, the automated assembly of the electronic cigarette 1 is facilitated, and the overall cost of the electronic cigarette 1 is reduced.

[0044] 3 , the atomizer assembly 20, the battery assembly 30 and the circuit board 40 are connected in sequence along the assembly direction. In this embodiment, the assembly direction is the length direction of the shell 10, that is, at least one end of the shell 10 is open. The atomizer assembly 20 is installed into the shell 10 from the open end of the shell 10 before the battery assembly 30, and then the battery assembly 30 and the circuit board 40 are installed in sequence, so that the circuit board 40 can be electrically connected to the battery assembly 30 and the atomizer assembly 20 at the same time, thereby realizing conduction between the internal components of the entire electronic cigarette 1.

[0045] Optionally, as shown in Figures 1 to 6, the battery assembly 30 includes a battery 31, a positive electrode connecting piece 33, and a negative electrode connecting piece 34. The battery 31 includes a battery body 311, a battery positive electrode 312, and a battery negative electrode 313. The battery positive electrode 312 and the battery negative electrode 313 are both located at one end of the battery body 311 adjacent to the circuit board 40. The circuit board 40 is integrated with a battery connecting terminal 41 and an atomizer assembly connecting terminal 42. The battery connecting terminal 41 is electrically connected to the battery positive electrode 312 and the battery negative electrode 313. One end of the positive electrode connecting piece 33 and the negative electrode connecting piece 34 are electrically connected to the atomizer assembly connecting terminal 42. The other ends of the positive electrode connecting piece 33 and the negative electrode connecting piece 34 are electrically connected to the atomizer assembly 20, so that the atomizer assembly connecting terminal 42 is electrically connected to the atomizer core 21 in the atomizer assembly 20.

[0046] When the battery 31 is connected to the circuit board 40 to power it, the battery's positive electrode 312 and negative electrode 313 are connected to the battery connection terminal 41. The atomizer assembly 20 is connected to the atomizer assembly connection terminal 42. This allows the circuit board 40 to be powered, powering the atomizer assembly 20 and operating the atomizer core 21, thereby atomizing the atomized medium that falls onto the atomizer core 21 into an aerosol for inhalation by the user. The battery assembly 30 abuts against the circuit board 40 along the assembly direction of the electronic cigarette 1.

[0047] As a result, the battery positive electrode 312 and the battery negative electrode 313 are located at the same end of the battery body 311, which facilitates the abutment of the battery 31 against the circuit board 40 when electrically connected to the circuit board 40. It also facilitates the distribution of the positions of the battery 31 and the circuit board 40, and increases the stability of the electrical connection between the circuit board 40 and the battery 31. The provision of the positive electrode connecting piece 33 and the negative electrode connecting piece 34 facilitates the electrical connection of the atomizer assembly 20 to the circuit board 40 via the positive and negative electrode connecting pieces 34.

[0048] In some embodiments, as shown in Figures 1, 5 and 6, the battery positive electrode 312 and the battery negative electrode 313 are both columnar structures, and a battery connector 43 is provided on the side surface of the circuit board 40 facing the battery assembly 30. The battery connector 43 is used to connect to the battery 31. The battery connection end 41 includes a battery positive electrode conductive insertion hole 431 and a battery negative electrode conductive insertion hole 432 formed on the battery connector 43. The battery positive electrode 312 and the battery negative electrode 313 are respectively fitted into the battery positive electrode conductive insertion hole 431 and the battery negative electrode conductive insertion hole 432 to achieve electrical connection between the circuit board 40 and the battery 31. That is, the end of the circuit board 40 adjacent to the battery 31 is a battery connection terminal 41, which is provided with a battery connector 43. The battery connector 43 is provided with a positive-electrode conductive insertion hole 431 and a negative-electrode conductive insertion hole 432 for connecting the battery positive electrode 312 and the battery negative electrode 313. When the battery 31 is connected to the circuit board 40, the positive-electrode 312 and the negative-electrode 313 are directly inserted into the positive-electrode conductive insertion hole 431 and the negative-electrode conductive insertion hole 432 to achieve a quick electrical connection between the battery 31 and the circuit board 40. Therefore, the provision of the positive-electrode conductive insertion hole 431 and the negative-electrode conductive insertion hole 432 facilitates the connection of the positive-electrode 312 and the negative-electrode 313 to the circuit board 40, improving the efficiency and precision of the assembly of the circuit board 40 and the battery 31.

[0049] In some embodiments, referring to FIG. 1 , the positive and negative conductive insertion holes 431 and 432 are spaced apart from each other. These holes extend through the battery connector 43 and the circuit board 40, respectively, along the assembly direction, i.e., the length of the housing 10. The spaced-apart arrangement of the positive and negative conductive insertion holes 431 and 432 prevents interference between the positive and negative electrodes 312 and 313, allowing the positive and negative electrodes 312 and 313 to be positioned opposite each other. The fact that the positive and negative conductive insertion holes 431 and 432 extend through the circuit board 40 facilitates the placement of the conductive holes and accommodates different lengths of positive and negative electrodes 312 and 313. This allows the circuit board 40 to accommodate a wider range of applications and batteries 31 of varying specifications, increasing its versatility.

[0050] Of course, the battery positive conductive insertion hole 431 and the battery negative conductive insertion hole 432 may not penetrate the circuit board 40 , that is, the battery positive conductive insertion hole 431 and the battery negative conductive insertion hole 432 form a closed structure on the side away from the battery 31 .

[0051] In some embodiments, as shown in Figures 3-6, the battery assembly 30 further includes a mounting bracket 32, a battery compartment 321 formed on the mounting bracket 32, the battery 31 being disposed within the battery compartment 321, a positive electrode connector 33 and a negative electrode connector 34 being spaced apart from each other and disposed on the mounting bracket 32, and the atomizer assembly connection terminal 42 being electrically connected to the atomizer assembly 20 via the positive electrode connector 33 and the negative electrode connector 34. For example, the mounting bracket 32 ​​is an annular structure, with the positive electrode connector 33 and the negative electrode connector 34 being mounted within the sidewalls of the mounting bracket 32, and extending outward from the ends of the mounting bracket 32 ​​along the assembly direction of the electronic cigarette 1. The battery 31 is disposed within the mounting bracket 32, and a support member 322 is disposed at one end of the mounting bracket 32 ​​adjacent to the circuit board 40. One end of the support member 322 is connected to the mounting bracket 32, and the other end of the support member 322 extends perpendicularly to the assembly direction toward the center of the mounting bracket 32. The support member 322 includes two sub-support members 322 spaced apart from each other. The positive electrode 312 and the negative electrode 313 of the battery are located between the two sub-support members 322. After the circuit board 40 and the battery 31 are assembled, the support member 322 abuts against the circuit board 40. The support members 322 and the mounting bracket 32 ​​together define the battery compartment 321. As a result, the spaced-apart positive and negative electrode connectors 33 and 34 prevent each other from interfering with each other, thereby preventing a short circuit.

[0052] In some embodiments, as shown in Figures 5, 6, and 8, the atomizer assembly connection end 42 includes a circuit board positive pin 421 and a circuit board negative pin 422, the positive connecting piece 33 has a positive slot 331, and the negative connecting piece 34 has a negative slot 341. The circuit board positive pin 421 and the circuit board negative pin 422 are respectively fitted into the positive slot 331 and the negative slot 341. The circuit board positive pin 421 and the circuit board negative pin 422 can be located on the same side of the circuit board 40, and the circuit board positive pin 421 and the positive slot 331 are opposite, and the circuit board negative pin 422 and the negative slot 341 are opposite, so that the atomizer assembly connection end 42 can be quickly positioned with the circuit board 40 after installation, and the positive slot 331 and the negative slot 341 are interference fit when connected to the positive connecting piece 33 and the negative connecting piece 34 to ensure the reliability of the connection.

[0053] In some embodiments, as shown in FIG6 , the positive electrode slot 331 is formed by bending one end of the positive electrode connecting piece 33 adjacent to the circuit board 40, and the negative electrode slot 341 is formed by bending one end of the negative electrode connecting piece 34 adjacent to the circuit board 40. The positive electrode connecting piece 33 is bent to form the positive electrode slot 331, which opens toward the circuit board 40. The positive electrode slot 331 mates with the positive electrode pin 421 of the circuit board. The negative electrode connecting piece 34 is bent to form the negative electrode slot 341, which opens toward the circuit board 40. The negative electrode slot 341 mates with the negative electrode pin 422 of the circuit board. Therefore, the setting of the positive pole slot 331 and the negative pole slot 341 facilitates the plug-in cooperation with the positive pole pin 421 and the negative pole pin 422 of the circuit board, simplifies the structure of the installation of the circuit board 40 and the connecting piece, improves the efficiency and accuracy of the cooperation between the circuit board 40 and the positive connecting piece 33 and the negative connecting piece 34, and can ensure that the positive pole pin 421 and the negative pole pin 422 of the circuit board maintain good contact with the connecting piece, thereby increasing the reliability of the circuit board 40.

[0054] In some embodiments, the end of the positive electrode connecting piece 33 adjacent to the circuit board 40 is a positive spring structure, and the end of the negative electrode connecting piece 34 adjacent to the circuit board 40 is a negative spring structure. The positive and negative spring structures are respectively electrically connected to the circuit board 40. The provision of the positive and negative spring structures facilitates abutment against the circuit board 40 when the connecting pieces are electrically connected to the circuit board 40, thereby increasing the reliability of the connection between the positive and negative electrode connecting pieces 33 and 34 and the circuit board 40.

[0055] Furthermore, the atomizer assembly connection end 42 includes a positive protrusion on the circuit board and a negative protrusion on the circuit board (not shown in the figure). The positive protrusion on the circuit board abuts against the positive spring structure, and the negative protrusion on the circuit board abuts against the negative spring structure. That is, a positive protrusion on the circuit board and a negative protrusion on the circuit board are provided on the side of the circuit board 40 where the battery connection end 41 is provided. The positive protrusion on the circuit board and the negative protrusion on the circuit board are used to abut against the positive connecting piece 33 and the negative connecting piece 34 to form an electrical connection between the circuit board 40 and the atomizer core 21. In this way, the part where the positive connecting piece 33 abuts against the positive protrusion on the circuit board and the part where the negative connecting piece 34 abuts against the negative protrusion on the circuit board are both spring structures. When abutting, the positive spring structure and the negative spring structure are squeezed to ensure the contact reliability and stability between the connecting piece and the protrusion. In some embodiments, in conjunction with Figures 3, 5 and 8, a microphone 44 is integrated on the surface of the side of the circuit board 40 away from the battery connection end 41 and the atomizer assembly connection end 42. Microphone 44 is a conversion device that can convert sound energy into electrical energy.

[0056] Optionally, an indicator light 45 is integrated on the circuit board 40 and is arranged corresponding to the air inlet 121. When the microphone 44 vibrates and generates electricity, the circuit board 40 lights up the indicator light 45. The indicator light 45 is arranged opposite to the air inlet 121 and can emit light through the air inlet 121, making it easier for the user to observe the working status of the electronic cigarette 1 and enhancing the user experience.

[0057] Furthermore, the indicator light 45 is disposed on a side of the circuit board 40 away from the battery connection terminal 41 and the atomizer assembly connection terminal 42. That is, the indicator light 45 and the microphone 44 are located on the same side of the circuit board 40, which facilitates the emission of light from the indicator light 45, making it easier for the user to observe the on and off of the light, thereby providing a better user experience. It also facilitates the layout of electrical components on the circuit board 40, helps improve the space utilization of the circuit board 40, and facilitates the integrated and miniaturized design of the circuit board 40.

[0058] In some embodiments, as shown in FIG3 , the circuit board 40 is provided on a side of the battery assembly 30 away from the atomizer assembly 20, and the circuit board 40 is electrically connected to the battery assembly 30 and the atomizer assembly 20. The battery assembly 30 is electrically connected to the circuit board 40 to supply power to the circuit board 40, and the circuit board 40 is electrically connected to the atomizer assembly 20. After the circuit board 40 is powered, power is provided to the atomizer assembly 20 so that the atomizer assembly 20 works to atomize the medium to be atomized into an aerosol for the user to inhale. Thus, the position of the circuit board 40 is set, even if the battery assembly 30 and the atomizer assembly 20 are both located on the same side of the circuit board 40, which facilitates the internal arrangement and space utilization of the electronic cigarette 1, and the circuit board 40 is set adjacent to the air inlet 121, which can facilitate timely maintenance when a fault occurs inside the electronic cigarette 1, thereby reducing the cost of use.

[0059] In some embodiments, as shown in conjunction with Figures 5 and 8 , the arrangement direction of the circuit board positive electrode pin 421 and the circuit board negative electrode pin 422 is perpendicular to the arrangement direction of the battery positive electrode conductive insertion hole 431 and the battery negative electrode conductive insertion hole 432. The arrangement of the pins and insertion holes can be specifically configured based on the mounting bracket 32 ​​of the battery assembly 30 and the arrangement position of the positive and negative electrode connecting pieces 34. In this embodiment, because the circuit board 40 is constrained by the position of the positive electrode connecting piece 33 and the negative electrode connecting piece 34 on the mounting bracket 32, the arrangement direction of the circuit board positive electrode pin 421 and the circuit board negative electrode pin 422 relative to each other is perpendicular to the arrangement direction of the battery positive electrode conductive insertion hole 431 and the battery negative electrode conductive insertion hole 432.

[0060] In this embodiment, the electronic cigarette 1 further includes a first sealing member 61 and a base 12. The base 12 is a part of the shell 10. That is, the shell 10 includes a shell body 11 and the base 12. The base 12 cooperates with the shell body 11 at the open end of the shell body 11 to achieve sealing of the shell body 11.

[0061] In conjunction with Figures 1 to 5, a movable switch 122 is provided on the base 12, which can control the size and switch of the air inlet 121, so that the user can inhale and the atomization work of the atomizer core 21 can proceed smoothly. A first seal 61 is provided between the base 12 and the circuit board 40. The first seal 61 and the base 12 jointly define a first air inlet channel 71 and a second air inlet channel 72. The center line of the air inlet 121 corresponding to the first air inlet channel 71 coincides with the center line of the electronic cigarette 1. After the first air inlet channel 71 takes in air, the incoming air will produce sound, causing the microphone 44 opposite to the first air inlet channel 71 to vibrate. The microphone 44 converts the vibration into an electrical signal. After the circuit board 40 recognizes the electrical signal, it controls the on and off of the indicator light 45. The light of the indicator light 45 can be emitted from the air inlet 121 corresponding to the first air inlet channel 71. For example, when a user inhales the aerosol atomized by the atomizer core 21, air is taken in by the first air inlet channel 71 and the second air inlet channel 72 at the same time. The air flows in the first air inlet channel 71 and causes the microphone 44 to vibrate and generate an electrical signal to light up the indicator light 45. The light of the indicator light 45 can be emitted from the air inlet port 121 opposite to the first air inlet channel 71, so that the user can know whether the electronic cigarette 1 is working, thereby enhancing the user's usage experience.

[0062] In addition, referring to Figure 6, the present application implants the positive and negative electrode connecting pieces 34 into a plastic mold, and through the injection molding process, the positive and negative electrode connecting pieces 34 are integrated with the plastic mounting bracket 32 ​​of the battery 31 to form an integral molded part. The positive electrode connecting piece 33 and the negative electrode connecting piece 34 are respectively arranged on both sides of the mounting bracket 32. A limiting rib 323 is provided at one end of the battery compartment 321 of the mounting bracket 32. The limiting rib 323 is provided with foam to abut the battery 31 to fix the battery 31. The limiting rib 323 and the support member 322 provided at the other end of the battery compartment 321 together form the assembly of the battery 31.

[0063] The mounting bracket 32 ​​and the housing 10 define the aforementioned second air inlet passage 72. A second seal 62 is provided at the end of the mounting bracket 32 ​​away from the circuit board 40. The second seal 62 engages with the mounting bracket 32. An annular rib is provided on the outer periphery of the second seal 62 for abutting against the inner wall of the housing 10, thereby sealing the assembly gap between the second seal 62 and the housing 10 and preventing leakage of the atomized medium.

[0064] As shown in Figures 2-4, the electronic cigarette 1 also includes an atomizer core fixing bracket 50 and a third seal 63. The third seal 63 is located at one end of the atomizer core fixing bracket 50 away from the second seal 62. The third seal 63 is sleeved over the end of the atomizer core fixing bracket 50 away from the second seal 62. The outer periphery of the third seal 63 is provided with a rib for sealing the assembly gap between the third seal 63 and the housing 10, while also sealing the inner wall of the oil storage tank 13, placing the medium to be atomized so that it flows into the atomization chamber 14. The atomizer core 21 is fixed to the atomizer core fixing bracket 50. The atomizer core fixing bracket 50 and the second seal 62 define the atomization chamber 14, which is connected to the second air inlet channel 72. The medium to be atomized in the oil storage tank 13 defined by the shell 10 flows to the atomizer core 21, and after being atomized by the atomizer core 21, flows to the air inlet 111. An air flow channel 74 is provided between the air inlet 111 and the atomizer tank 14. The medium to be atomized may be tobacco oil.

[0065] The upper end surface of the second sealing member 62 is provided with a sealing positioning groove, and the lower end surface of the atomizer core fixing bracket 50 is provided with a sealing positioning rib. The sealing positioning rib and the sealing positioning groove are interference-fitted and arranged one-to-one to prevent the atomized medium in the oil storage tank 13 from leaking into the second air inlet channel 72. An air inlet hole 73 is provided in the center of the second sealing member 62, and an air inlet hole is also provided in the middle area of ​​the mounting bracket 32. The air inlet hole 73 is connected to the second air inlet channel 72. Air entering from the air inlet 121 enters the atomizer chamber 14 through the second air inlet channel 72 and the air inlet hole 73, and finally flows out through the air flow channel 74.

[0066] The housing 10 is made of plastic, which can be opaque, translucent, or transparent. An airflow channel 74 is provided in the center of the housing 10, communicating with the outside atmosphere. The aerosol generated by the heated atomizer core 21 mixes with the air and is then discharged from the air inlet 111 through the airflow channel 74.

[0067] 4 and 7 , the atomizer core 21 includes a main body of the atomizer core 21 and a heating element 22 . The heating element 22 can be wound around the outer peripheral surface of the main body of the atomizer core 21 . The atomizer core 21 is assembled between the atomizer core fixing bracket 50 and the second sealing member 62 . The second sealing member 62 can be provided with a positioning groove. The atomizer core 21 can be fixed in the positioning groove by the heating element 22 . The medium to be atomized inside the oil storage tank 13 can flow to the atomizer core 21 , so that the atomizer core 21 can absorb the medium to be atomized and form an aerosol under the action of the heating element 22 , which enters the atomization bin 14 and flows out from the air flow channel 74 connected to the atomization bin 14 .

[0068] 2 and 10 , an annular air path groove 51 is formed between the outer peripheral surface of the atomizing core fixing bracket 50 and the shell 10. The annular air path groove 51 extends around the assembly direction of the shell 10. A third sealing member 63 is provided at one end of the annular air path groove 51. The third sealing member 63 is configured to connect the atomizing bin 14 and the oil storage bin 13 when the pressure difference between the atomizing bin 14 and the oil storage bin 13 is greater than a predetermined value, and to cut off the connection between the atomizing bin 14 and the oil storage bin 13 when the pressure difference between the atomizing bin 14 and the oil storage bin 13 is less than or equal to a predetermined value.

[0069] Under the action of the user's inhalation, a negative pressure environment is formed in the atomization chamber 14. The pressure in the annular air path groove 51 is now greater than the pressure in the oil storage chamber 13 and the atomization chamber 14. The airflow entering from the air inlet 121 flows through the atomization core fixing bracket 50 into the oil storage chamber 13, achieving pressure balance between the inside of the oil storage chamber 13 and the air inlet 121, facilitating the flow of the atomized medium in the oil storage chamber 13 to the atomization core 21 for atomization to form an aerosol. The aerosol generated after the atomization of the atomization core 21 flows to the air inlet 111 through the atomization chamber 14 and the air flow channel 74. An annular air path groove 51 is formed between the outer circumference of the atomization core fixing bracket 50 and the housing 10. That is, the annular air path groove 51 can be provided on the outer circumference of the atomization core fixing bracket 50, or the annular air path groove 51 can be provided on the inner circumference of the housing 10 opposite to the atomization core fixing bracket 50. When air flows toward the atomizer core fixing bracket 50, an annular air path groove 51 is provided on the outer circumferential surface of the atomizer core fixing bracket 50. The annular air path groove 51 extends on the outer circumferential surface of the atomizer core fixing bracket 50 along the central axis of the atomizer core fixing bracket 50. When the pressure difference between the atomizer bin 14 and the oil storage bin 13 is greater than a predetermined value, the atomizer bin 14 is connected to the air inlet 121. When the pressure at the air inlet 121 is greater than the pressure inside the oil storage bin 13, the resulting pressure differential causes the third sealing member 63 to deform and connect the atomizer bin 14 and the oil storage bin 13. The atomized medium in the oil storage bin 13 can flow toward the atomizer core 21 for atomization. When the pressure difference between the atomizer bin 14 and the oil storage bin 13 is less than or equal to the predetermined value, the third sealing member 63 recovers its deformation to isolate the connection between the atomizer bin 14 and the oil storage bin 13.

[0070] Similarly, when the annular air path groove 51 is provided on the inner circumferential surface of the housing 10, the annular air path groove 51 extends along the central axis of the atomizer core fixing bracket 50 on the inner circumferential surface of the housing 10. The principle of connecting and separating the atomizer chamber 14 and the oil storage tank 13 is the same as that of the annular air path groove 51 provided on the atomizer core fixing bracket 50, and will not be further described. In this embodiment, the annular air path groove 51 provided on the outer circumferential surface of the atomizer core fixing bracket 50 is used as an example.

[0071] According to the atomization device of the embodiment of the present application, by providing an annular air path groove 51 between the outer peripheral surface of the atomizer core fixing bracket 50 and the shell 10, it is possible to facilitate external airflow to enter the oil storage tank 13 from the air inlet 121, balance the pressure inside the oil storage tank 13, and facilitate the smooth flow of the atomized medium stored in the oil storage tank 13 to the atomizer core 21, so that the atomizer core 21 can work normally. At the same time, the annular air path groove 51 can increase the path length of the external airflow to flow into the oil storage tank 13, so that the annular air path groove 51 has the function of oil storage and flow resistance, thereby preventing the atomized medium inside the oil storage tank 13 from leaking from the annular air path groove 51.

[0072] In some embodiments, as shown in Figures 2 and 10, the annular air path groove 51 communicates with the oil storage tank 13 through the ventilation groove 52. At least a portion of the third sealing member 63 is located between the inner wall surface of the housing 10 and the atomizer core fixing bracket 50 to seal the gap formed between the atomizer core fixing bracket 50 and the housing 10, thereby reducing the possibility of leakage of the atomized medium inside the oil storage tank 13 through the gap and increasing the stability of the atomizer core fixing bracket 50 installed in the housing 10. The ventilation groove 52 is provided on the outer circumferential surface of the atomizer core fixing bracket 50 and extends along the assembly direction. The ventilation groove 52 communicates with the connecting groove provided in the annular air path groove 51. The third sealing member 63 is provided with at least one ventilation elastic portion 631, which covers the end of the ventilation groove 52 facing the oil storage tank 13. The ventilation elastic portion 631 is disposed at the end of the atomizer core fixing bracket 50 away from the air inlet 121. The ventilation elastic portion 631 is disposed between the atomizer core fixing bracket 50 and the oil storage tank 13, and connects the oil storage tank 13 and the atomizer tank 14. When a user inhales aerosol, the pressure inside the oil storage tank 13 decreases. When the pressure at the air inlet 121 is greater than the pressure in the oil storage tank 13, the ventilation elastic portion 631 deforms under the pressure difference between the two to open the ventilation groove 52. For example, the air pressure inside the ventilation groove 52 pushes open the ventilation elastic portion 631 at the end of the ventilation groove 52, allowing the airflow inside the ventilation groove 52 to flow toward the oil storage tank 13, achieving pressure balance within the oil storage tank 13. When the pressure at the air inlet 121 is no greater than the pressure in the oil storage tank 13, the ventilation elastic portion 631, under the action of its own elastic force, blocks the ventilation groove 52.

[0073] Therefore, a ventilation groove 52 is provided on the atomizer core fixing bracket 50, and the ventilation elastic portion 631 is provided to separate the ventilation groove 52 and the oil storage tank 13. When a pressure difference occurs between the air pressure in the ventilation groove 52 and the air pressure in the oil storage tank 13, the air pressure in the ventilation groove 52 can overcome the elasticity of the ventilation elastic portion 631 and push the ventilation elastic portion 631 open to enter the oil storage tank 13, thereby balancing the air pressure in the oil storage tank 13. At the same time, the implementation method and structure are relatively simple and effective, and the third sealing member 63 can form a seal for the ventilation groove 52.

[0074] Specifically, with reference to Figure 5, when a user inhales, the microphone 44 on the circuit board 40 generates negative pressure through the first air inlet channel 71 above, turning on the switch 122 of the electronic cigarette 1 and starting operation. The sensor set in the electronic cigarette 1 is triggered, sending a signal to drive the positive and negative connecting pieces 34 at both ends of the mounting bracket 32 ​​to connect one by one, and the heating element 22 begins to heat. The atomized medium is heated and atomized. At the same time, outside air first enters from the air inlet 121 of the base 12, passes through the second air inlet channel 72, the second sealing member 62, and the air inlet hole 73 of the mounting bracket 32, mixes with the aerosol heated by the heating element 22, and flows out from the middle atomization space of the atomizer core 21 and enters the user's mouth through the air flow channel 74. As the aerosol is generated, the atomized medium is gradually adsorbed by the heating element 22, and the air pressure on one side of the oil storage tank 13 drops, forming a negative pressure. Due to the high and low pressure differential, the external atmospheric pressure enters the upper oil storage tank 13 through the ventilation channel 75 formed by the atomizer core fixing bracket 50 and the third sealing member 63, achieving pressure balance between the internal and external pressures of the oil storage tank 13. Furthermore, the oil in the oil storage tank 13 flows smoothly, allowing the atomizer core 21 to absorb sufficient atomized medium for atomization.
