Description

Technical Field

[0002] With the continuous development of electronic atomization technology, various electronic atomization products have emerged on the market. The atomization components of some electronic atomizers are replaceable. Such electronic atomizers mostly adopt a one-time air intake method, and external gas sequentially passes through the battery housing, the base of the atomization component, the atomization core air passage, and the mouthpiece housing. However, there is usually a risk of air leakage. For example, there is a gap in the assembly between the atomization component and the battery housing. Air leakage will cause instability in the draw resistance, and at the same time will lead to a decrease in the negative pressure difference, reducing the sensitivity of the airflow sensing component. Some electronic atomizers also have an adjustment device for adjusting the draw resistance, and there is also an assembly gap between the adjustment device and the battery housing. To solve the air leakage problems in various places, various sealing structures or various seals are provided inside the electronic atomizer, resulting in a complex internal assembly structure and a relatively high overall cost.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0043] Please refer to Figures 1 to 5 together, and now an elastic seal 30 provided by an embodiment of this application will be described. The elastic seal 30 can but is not limited to being made of sealing silica gel. The elastic seal 30 is provided with an air inlet cavity 301 and an installation cavity 320 that communicate with each other. The elastic seal 30 is configured to be in sealing contact with the inner wall of the housing 10 of the electronic atomization device, the bottom surface of the atomization assembly 20, and the air regulating member 13 respectively. The installation cavity 320 is used to accommodate the airflow sensing assembly 40 in the housing 10. The airflow channel 201 of the atomization assembly 20 can communicate with the air inlet hole 120 of the housing 10 through the air inlet cavity 301. In this way, when the elastic seal 30 is installed in the electronic atomization device, it can be in elastic sealing contact with the inner wall of the housing 10 of the electronic atomization device, the bottom surface of the atomization assembly 20, and the air regulating member 13 respectively, effectively preventing leakage at each connection, and thus ensuring the sensitivity of the airflow sensing assembly 40 and the stability of the suction resistance. Compared with the conventional method of using multiple seals or multiple sealing structures to achieve sealing, using a single component can achieve sealing at various places, optimizing the sealing structure of the corresponding electronic atomization device, making the assembly of the electronic atomization device simpler and more convenient, and at the same time reducing the manufacturing cost of the corresponding electronic atomization device.

[0044] Refer to Figures 1 to 3 and Figure 5 as shown, the elastic seal 30 includes a first sealing portion 31, a second sealing portion 32, and a third sealing portion 33 that are connected in sequence from top to bottom, and each sealing portion is integrally formed. The first sealing portion 31 is used for sealing contact with the bottom surface of the atomization assembly 20, and the third sealing portion 33 is used for sealing contact with the air regulating member 13. The second sealing portion 32 is provided with an installation cavity 320, that is, the airflow sensing assembly 40 is installed in the second sealing portion 32. The air inlet cavity 301 extends from the first sealing portion 31 to the third sealing portion 33. The upper and lower ends of the air inlet cavity 301 are respectively open, being a cavity that penetrates up and down. The opening at the bottom of the third sealing portion 33 is the inlet of the air inlet cavity 301, and the opening at the top of the first sealing portion 31 is the outlet of the air inlet cavity 301.

[0045] The first sealing portion 31 encloses an annular accommodation cavity 310, and the air inlet cavity 301 extends from the third sealing portion 33 to the accommodation cavity 310. The first sealing portion 31 is a thin-wall structure, and a circle of thin walls encloses the accommodation cavity 310. As Figure 2As shown, the accommodation cavity 310 is a cavity with a gradually widening opening from bottom to top, so that the first sealing portion 31 is not easily curled inward after being squeezed and leakage occurs.

[0046] The second sealing portion 32 is provided with a stepped hole 324. The stepped hole 324 includes a small-diameter hole 326 and a large-diameter hole 325. The aperture of the large-diameter hole 325 is larger than that of the small-diameter hole 326. The large-diameter hole 325 is adapted to the airflow sensing assembly 40. The hole wall of the large-diameter hole 325 encloses an installation cavity 320. The large-diameter hole 325 is used to seal the airflow sensing assembly 40. The accommodation cavity 310 can communicate with the sensing membrane of the airflow sensing assembly 40 through the small-diameter hole 326, so that the airflow sensing assembly 40 can sense the air pressure change.

[0047] The circumferential contour dimensions of the first sealing portion 31 and the circumferential contour dimensions of the third sealing portion 33 are set to be smaller than the circumferential contour dimensions of the second sealing portion 32. In this way, the protruding part of the periphery of the second sealing portion 32 relative to the peripheries of the first sealing portion 31 and the third sealing portion 33 forms a convex edge 321. That is to say, the elastic seal 30 has a circumferential contour that is larger in the middle and smaller on the upper and lower sides. Other components in the electronic atomization device can press and fix the elastic seal 30 in the housing 10 by means of the convex edge 321.

[0048] Refer to Figures 4 to 6 , the electronic atomization device provided by the embodiment of the present application will now be described. The electronic atomization device has a replaceable atomization assembly and adjustable air intake. The electronic atomization device includes a housing 10 and an atomization assembly 20. The housing 10 includes an outer shell 11 and a bottom shell 12 clamped to the lower end of the outer shell 11. The bottom shell 12 is provided with an air intake hole 120. The top of the outer shell 11 is provided with a hanging portion 111 for hanging a rope. As Figure 7 shown, the atomization assembly 20 is detachably arranged in the outer shell 11, that is, the atomization assembly 20 is a replaceable component. The atomization assembly 20 and the housing 10 can be assembled together by a magnetic attraction connection or other detachable connection structures. It can be understood that the atomization assembly 20 can also be set as a non-replaceable component, that is, the atomization assembly 20 is fixed to the housing 10 and the atomization assembly 20 cannot be pulled out of the housing 10.

[0049] An air intake adjustment member 13 is provided at the air intake hole 120 of the bottom shell 12, and the suction resistance can be adjusted through the air intake adjustment member 13. At least two air intake adjustment holes 132 are opened on the air intake adjustment member 13. The air intake hole 120 communicates with the accommodation cavity 310 through the air intake adjustment holes 132, and the number of the air intake adjustment holes 132 can be increased according to requirements. The air intake adjustment member 13 is movably arranged on the bottom shell 12, and the air intake adjustment member 13 can be slidably or rotatably arranged on the bottom shell 12. Specifically, the air intake adjustment member 13 is slidably connected to the bottom shell 12. By sliding the air intake adjustment member 13, the number of the air intake adjustment holes 132 in communication can be adjusted, thereby changing the suction resistance of the air intake hole 120. During the sliding process of the air intake adjustment member 13, at least one air intake adjustment hole 132 is aligned with the accommodation cavity 310.

[0050] Refer to Figure 4 and Figure 5 , a mouthpiece 22 is provided at the top of the atomization assembly 20. A sleeve 23 is fixed inside the atomization assembly 20. The sleeve 23 encloses an oil chamber. An oil storage part 24 is provided in the oil chamber. A heating unit 25 is arranged at the center of the oil storage part 24. An upper silica gel 26 is provided at the upper part of the oil chamber, and a lower silica gel 27 is provided at the lower part of the oil chamber. An oil absorption cotton 28 is provided between the upper silica gel 26 and the oil storage part 24. The atomization assembly 20 is provided with an air flow channel 201. A bottom cover 21 is provided at the bottom of the atomization assembly 20. One end of the elastic seal 30 is in sealed contact with the bottom surface of the bottom cover 21. At least one air inlet 210 is formed on the bottom surface of the bottom cover 21, and the air inlet 210 forms an inlet of the air flow channel 201. An air flow sensing assembly 40 is provided inside the housing 10. The air flow sensing assembly 40 responds by sensing air pressure changes, triggers the control circuit, and the heating unit 25 starts to work to generate aerosol for inhalation.

[0051] Refer to Figures 1 to 3 and Figure 5 , an elastic seal 30 is further provided inside the housing 10. The elastic seal 30 is in sealed contact with the inner wall of the outer shell 11, the bottom surface of the atomization assembly 20, and the air regulating member 13. The elastic seal 30 can be made of, but is not limited to, silica gel material. In this embodiment, the elastic seal 30 is made of sealing silica gel. The elastic seal 30 is provided with an air inlet cavity 301 and a mounting cavity 320. The upper and lower ends of the air inlet cavity 301 are respectively open, and it is a cavity that penetrates up and down. The air inlet cavity 301 is communicated with the mounting cavity 320. The air flow sensing assembly 40 is accommodated and fixed in the mounting cavity 320, and at least the side wall of the air flow sensing assembly 40 is in sealed contact with the side wall of the mounting cavity 320. The air flow channel 201 is communicated with the air inlet hole 120 at the bottom of the housing 10 through the air inlet cavity 301. That is to say, by providing the elastic seal 30, leakage at the corresponding connection parts between the outer shell 11 and the bottom shell 12, between the atomization assembly 20 and the outer shell 11, and between the air regulating member 13 and the outer shell 11 can be prevented, the sensitivity of the air flow sensing assembly 40 is ensured, the overall suction resistance of the electronic atomization device is more stable, and it is more convenient to use; at the same time, using a single component can solve the air leakage risks at the above three places. Compared with the method of separately providing sealing structures or seals at the assembly parts of each component, its processing is simple, the assembly between components is convenient, and the manufacturing cost is reduced.

[0052] Combined with reference to Figure 4 and Figure 5 , Figure 5The arrow in the figure shows the gas flow direction. During inhalation, the gas flow process is as follows: External gas enters through the air inlet hole 120, then enters the air inlet cavity 301 of the elastic seal 30 through the air adjustment hole 132 of the air adjustment member 13, then enters the air flow channel 201 through the air inlet 210 of the bottom cover 21 of the atomization assembly 20, and finally flows out from the outlet of the air flow channel 201, that is, the opening at the top of the mouthpiece 22.

[0053] Refer to Figure 5 、 Figure 8 For details, the housing 11 includes a main housing 110 and a bracket 14. The main housing 110 is fixedly connected to the bracket 14 by snap connection, and the bottom shell 12 is fixedly connected to the bracket 14 by snap connection. A convex ring 140 is protruded on the inner peripheral wall of the bracket 14, and a first magnetic attraction member 142 is fixed inside the convex ring 140. A second magnetic attraction member 220 is provided at the position of the bottom cover 21 corresponding to the first magnetic attraction member 142. The first magnetic attraction member 142 and the second magnetic attraction member 220 attract each other. In this way, when the atomization assembly 20 is inserted into a predetermined position in the housing 10, the atomization assembly 20 is fixed relative to the housing 10 by this magnetic attraction method. The atomization assembly 20 is inserted into the cavity above the convex ring 140 inside the bracket 14, and the outer peripheral wall of the elastic seal 30 is in sealing contact with the inner peripheral wall of the convex ring 140. In this way, by providing the elastic seal 30, leakage at the connection between the bottom shell 12 and the bracket 14 is avoided.

[0054] Refer to Figures 1 to 3 and Figure 5 For details, the elastic seal 30 includes a first seal part 31, a second seal part 32 and a third seal part 33 which are connected in sequence from top to bottom. The top end of the first seal part 31 is in sealing contact with the bottom surface of the atomization assembly 20, that is, the first seal part 31 is in elastic sealing contact with the bottom cover 21 at the bottom of the atomization assembly 20. The bottom end of the third seal part 33 is in sealing contact with the air adjustment member 13. An installation cavity 320 is provided in the second seal part 32 to fix the air flow induction assembly 40, and the outer peripheral wall of the second seal part 32 is in sealing contact with the inner peripheral wall of the convex ring 140. The first seal part 31 encloses an annular accommodation cavity 310, that is, the first seal part 31 has a thin-walled structure and forms the accommodation cavity 310 around the top surface of the second seal part 32. The air inlet cavity 301 extends from the third seal part 33 to the accommodation cavity 310, and the inlet of the air flow channel 201 faces the accommodation cavity 310, that is, the accommodation cavity 310 forms a part of the air inlet cavity 301. The air inlet cavity 301 is a cavity with openings at both upper and lower ends. While the second seal part 32 seals the air flow induction assembly 40, the air inlet cavity 301 is communicated with the induction film of the air flow induction assembly 40.

[0055] The circumferential profile dimensions of both the first sealing portion 31 and the third sealing portion 33 are smaller than the circumferential profile dimension of the second sealing portion 32. In this way, the peripheral edge of the second sealing portion 32 protrudes relative to the peripheral edges of the sealing portions on both sides, and the protruding part constitutes a convex edge 321. The flange 141 of the convex ring 140 abuts against the convex edge 321, thereby pressing the elastic seal 30 tightly against the circuit board 51.

[0056] Refer to Figures 1 to 3 and Figure 5 As shown in

[0057] Refer to Figure 5 , Figure 8 and Figure 9 , a power supply assembly 50 is provided in the housing 10. The power supply assembly 50 includes a circuit board 51 and a battery 52 which are electrically connected. The circuit board 51 is arranged horizontally and is fixed in the chamber surrounded by the bottom case 12. The bracket 14 forms a battery accommodation cavity 143 beside the atomization assembly 20. The battery 52 is vertically fixed in the battery accommodation cavity 143 and is located above one end of the circuit board 51. The airflow sensing assembly 40 is fixed on the top surface of the circuit board 51. The third sealing portion 33 passes through and is clamped to the first circuit board 51. The third sealing portion 33 is provided with an annular groove 330 at the connection with the second sealing portion 32. After passing through the circuit board 51, the third sealing portion 33 is clamped to the circuit board 51 through the annular groove 330. The entrance of the third sealing portion 33 is arranged in a trumpet shape with a smaller upper part and a larger lower part. A clamping portion 331 protrudes from the outer peripheral surface of the third sealing portion 33. The side wall of the upper section of the clamping portion 331 is in a vertical state. The lower section of the clamping portion 331 is a reduced-diameter section, and its circumferential profile dimension gradually decreases from top to bottom. In this way, an annular groove 330 for clamping the circuit board 51 is formed between the upper section of the clamping portion 331 and the second sealing portion 32. The lower section of the clamping portion 331 is formed with a tapered surface with a larger upper part and a smaller lower part, which is beneficial to the operation of the third sealing portion 33 passing through the circuit board 51.

[0058] The first electrode 511 is provided on the circuit board 51, and the second electrode 29 is provided on the bottom cover 21. The second electrode 29 is connected to the electrode pin of the heating element of the heating unit 25. When the atomization assembly 20 is inserted into the housing 10, the second electrode 29 is in contact with the first electrode 511, thus forming an electrical connection and further supplying power to the heating element of the heating unit 25. The elastic seal 30 is provided with a through hole corresponding to the position of the first electrode 511. A hollow extension column is provided on the bottom surface of the accommodation cavity 310 of the first sealing portion 31 corresponding to the through hole. The top end of the first electrode 511 passes through the extension column and is in contact with the second electrode 29, thereby achieving electrical connection.

[0059] Refer to Figure 1 , Figure 5 and Figure 8 , the convex ring 140 presses the second sealing portion 32 against the circuit board 51. Specifically, a flange 141 is radially extended from the inner peripheral wall of the convex ring 140, and the flange 141 abuts against the top surface of the periphery of the second sealing portion 32. The convex ring 140 presses the second sealing portion 32 against the circuit board 51 through the flange 141. That is, the circumferential contour dimension of the second sealing portion 32 is larger than that of the first sealing portion 31. The second sealing portion 32 has a protruding edge 321 extending relative to the first sealing portion 31, and the flange 141 of the convex ring 140 abuts against the protruding edge 321, thus pressing and fixing the elastic seal 30 to the circuit board 51.
