[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figure 1-7 As shown, this embodiment provides an electronic cigarette, which includes a housing 1, a sealing member 2, and a microphone 3. The housing 1 includes a receiving cavity 11 and a suction cavity 12. The sealing member 2 is disposed inside the housing 1 to separate the receiving cavity 11 and the suction cavity 12. The sealing member 2 is provided with a mounting groove 23 facing the receiving cavity 11. The sealing member 2 is provided with an air passage 231 that connects the mounting groove 23 and the suction cavity 12. The microphone 3 is disposed in the mounting groove 23.

[0043] The housing 1 is provided with a suction hole 13, which is connected to the suction chamber 12. In use, the smoker can inhale through the suction hole 13, which generates negative pressure in the suction chamber 12. The air passage 231 of the seal 2 can trigger the microphone 3 in the mounting groove 23, which in turn triggers the tobacco cartridge 6 in the suction chamber 12 to produce smoke.

[0044] The electronic cigarette uses a seal 2 to separate the housing cavity 11 and the suction cavity 12 of the housing 1. The seal 2 is provided with a mounting groove 23 and an air passage 231, so that the microphone 3 can be directly installed in the mounting groove 23 and can be triggered through the air passage 231. With the help of the seal 2, the structure of the electronic cigarette is simplified, the number of parts is reduced, the production cost is reduced, and the fewer parts simplify the assembly process and improve the assembly efficiency.

[0045] The outer ring of the seal 2 is fitted with a first sealing ring 21. The plane of the first sealing ring 21 is perpendicular to the extension direction of the housing 1. The first sealing ring 21 is used to abut against the inner wall of the housing 1. The setting of the first sealing ring 21 makes the sealing effect between the receiving cavity 11 and the suction cavity 12 better, which is conducive to the transmission of negative pressure and makes the smoking effect more realistic.

[0046] The seal 2 is provided with a relief groove 24, which connects to the receiving cavity 11. The relief groove 24 allows the receiving cavity 11 to provide a larger receiving space.

[0047] In another embodiment, the seal 2 includes a sealing body 20 and a first sealing ring 21, the first sealing ring 21 being disposed around the outer periphery of the sealing body 20. In this embodiment, the sealing body 20 and the first sealing ring 21 are integrally formed. The integral forming of the sealing body 20 and the first sealing ring 21 reduces the number of parts in the seal 2, thereby improving assembly efficiency.

[0048] Furthermore, at least two first sealing rings 21 are provided, and the at least two first sealing rings 21 are spaced apart along the extending direction of the housing 1. The housing 1 extends along the Z direction. The arrangement of the two first sealing rings 21 further improves the sealing effect between the receiving cavity 11 and the suction cavity 12. The Z direction is perpendicular to the vertical direction and perpendicular to the horizontal direction.

[0049] A second sealing ring 22 is provided on the inner wall of the mounting groove 23. The plane of the second sealing ring 22 is perpendicular to the extension direction of the mounting groove 23, and the second sealing ring 22 is used to wrap around the microphone 3. The mounting groove 23 extends along the Z direction. The second sealing ring 22 improves the sealing effect between the microphone 3 and the mounting groove 23, prevents air leakage, facilitates the transmission of negative pressure, and makes the smoking effect more realistic. The second sealing ring 22 is integrally formed on the inner wall of the mounting groove 23.

[0050] At least two second sealing rings 22 are provided, and the at least two second sealing rings 22 are spaced apart along the extension direction of the mounting groove 23. The arrangement of two second sealing rings 22 further improves the sealing effect between the microphone 3 and the mounting groove 23. In addition, the way the two second sealing rings 22 are spaced apart along the extension direction of the mounting groove 23 allows the microphone 3 to be stably supported, preventing the microphone 3 from tilting within the mounting groove 23. Of course, in other embodiments, three, four, or even five second sealing rings 22 can be provided. The specific number can be reasonably set according to the length and structure of the microphone 3. The more second sealing rings 22 there are, the better they can adapt to the outer contour shape of the microphone 3 and the better they can improve the sealing performance between the microphone 3 and the mounting groove 23. In this embodiment, the cross-section of the second sealing ring 22 can be semi-circular.

[0051] To prevent the microphone 3 from tilting in the mounting groove 23, a second sealing ring 22 can be provided, and the cross-section of the second sealing ring 22 is rectangular to increase the contact area with the microphone 3. Optionally, the width dimension of the second sealing ring 22 along the Z direction is greater than or equal to half the length dimension of the microphone 3 along the Z direction.

[0052] Generally, to install the cartridge 6, a bracket needs to be installed inside the suction chamber 12, and the bracket needs to be fixedly connected to the side wall of the suction chamber 12 to achieve relative fixation between the cartridge 6 and the housing 1. In this embodiment, the surface of the sealing member 2 facing the suction chamber 12 is the top surface 26, and the cartridge 6 located inside the suction chamber 12 abuts against the top surface 26. This arrangement allows the sealing member 2 to also be used as a bracket, reducing the need for brackets, further reducing costs, and improving assembly efficiency. In addition, reducing the need for brackets saves internal space in the housing 1, allowing for more flexible arrangement of other components.

[0053] In order to achieve the connection between the components inside the accommodating cavity 11 and the components inside the suction cavity 12, in this embodiment, the sealing member 2 is provided with a through hole 25, which connects the accommodating cavity 11 and the suction cavity 12. The cable 61 passes through the through hole 25, and its two ends are located in the suction cavity 12 and the accommodating cavity 11, respectively.

[0054] Specifically, one end of the through hole 25 connects to the clearance groove 24, and the other end of the through hole 25 connects to the suction chamber 12. A battery 51 is housed within the accommodating cavity 11. One end of the cable 61 of the cartridge 6 is electrically connected to the battery 51, and the other end is electrically connected to the heating element 62 of the cartridge 6 within the suction chamber 12. When the microphone 3 is triggered, the cartridge 6 generates smoke. Specifically, the heating element 62 is wrapped around wicking cotton. When the microphone 3 is triggered, the heating element 62 heats up, and the wicking cotton generates smoke. Of course, in other embodiments, the connection between the components inside the accommodating cavity 11 and the components inside the suction chamber 12 can be achieved wirelessly. The cartridge 6 also includes a container 63, and the heating element 62 is located within the container 63. The support for the cartridge 6 can be understood as the support for the container 63.

[0055] Since the sealing element 2 is made of rubber, and the clearance groove 24 reduces the thickness of the sealing element 2 in the Z direction, to improve the support performance for the cartridge 6, in this embodiment, the electronic cigarette includes a mounting bracket 4. The mounting bracket 4 is used to mount the electronic component 5. The mounting bracket 4 is installed in the receiving cavity 11, and one end of the mounting bracket 4 is inserted into the clearance groove 24 and abuts against the bottom of the clearance groove 24. This arrangement provides strong support for the bottom of the clearance groove 24, allowing the cartridge 6 to be stably supported; on the other hand, it provides a mounting position for the electronic component 5, making the installation of the electronic component 5 more convenient. The electronic component 5 includes a battery 51, a controller, and a circuit board 52. The battery 51 and the circuit board 52 are electrically connected. Both the controller and the battery 51 are fixed on the circuit board 52. The battery 51 is used to power the controller and the heating element 62. Optionally, the battery 51 is a rechargeable lithium battery. The charging port of the battery 51 is located at the end of the housing 1 away from the suction hole 13.

[0056] In this embodiment, one end of the mounting bracket 4 has a support portion, which is located within the clearance groove 24 and abuts against a portion of the inner wall of the clearance groove 24. The inner wall of the clearance groove 24 abutting against the support portion is disposed opposite to the outer wall of the clearance groove 24 that contacts the housing 1. In other words, the support portion abuts against the upper, lower, and left inner walls of the clearance groove 24 to support the clearance groove 24 and prevent the clearance groove 24 from collapsing and failing to achieve a sealing effect. Specifically, the mounting bracket 4 includes a base 41 and a cover 42. The electronic component 5 is mounted on the base 41, and the cover 42 covers the base 41. In addition, the second protrusion 421 at one end of the cover 42 and the first protrusion 414 at one end of the base 41 form the support portion. To further improve the support performance of the seal 2, in this embodiment, the seal 2 has an upper support groove 27 on the upper side of the mounting groove 23 and a lower support groove 28 on the lower side of the mounting groove 23. The base 41 has a lower support protrusion 411, and the cover 42 has an upper support protrusion. The upper support protrusion is inserted into the upper support groove 27, and the lower support protrusion 411 is inserted into the lower support groove 28. This arrangement ensures that, on the one hand, the outer wall of the clearance groove 24 will not collapse when separating the receiving cavity 11 and the suction cavity 12, provided that the seal 2 has a clearance groove 24. On the other hand, the mounting cavity formed between the cover 42 and the base 41 protects the electronic components 5 partially housed within it, and the separate design of the cover 42 and the base 41 facilitates the installation of the electronic components 5.

[0057] The support plate 412 is integrally formed on the end of the first protrusion 414 near the seal 2.

[0058] The base 41 includes a support plate 412 that abuts against the bottom of the clearance groove 24 to support the tobacco cartridge 6. The bottom and top surface 26 of the clearance groove 24 are parallel and opposite to each other. The support plate 412 has two spaced-apart cable channels 413 through which the cable 61 supplies power to the heating element 62 in the suction chamber 12.

[0059] The base 41 has a first support abutment surface 415 on the outer side of the first protrusion 414, and the cover 42 has a second support abutment surface 422 on the outer side of the second protrusion 421. The end of the seal 2 away from the top surface 26 has a sealing abutment surface 29, which abuts against the first support abutment surface 415 and the second support abutment surface 422. The first support abutment surface 415 and the second support abutment surface 422 form an annular support surface, abutting against the end faces of the clearance groove 24 and the mounting groove 23. This structure provides support for the side walls of the clearance groove 24 and the mounting groove 23. Within the entire housing 1, the mounting bracket 4 provides all-around support for the seal 2 in the Z direction, further preventing deformation of the seal 2 that could lead to seal failure, and improving the seal 2's support capacity for the cartridge 6. Optionally, the width of the annular support surface is the same as the thickness of the clearance groove 24 wall and the same as the thickness of the mounting groove 23 wall.

[0060] Optionally, the cover 42 and the base 41 are snap-fitted together. Of course, in other embodiments, the cover 42 and the base 41 can be screwed or glued together.

[0061] In this embodiment, the housing 1 is provided with an observation hole 14, which is connected to the suction chamber 12. Through the observation hole 14, at least the cartridge 6 inside the suction chamber 12 can be observed. In addition, the sealing member 2 can also be observed through the observation hole 14, so as to clearly see whether the cartridge 6 and the top surface 26 are in contact and have completed a firm connection. There are two observation holes 14, which are respectively located on both sides of the housing 1.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
