[0004] However, the existing resilient seals and first mounting brackets are not easy to assemble. Utility Model Content

[0005] Therefore, it is necessary to provide an atomizing device that facilitates the assembly of the elastic seal with the first mounting bracket to address the above-mentioned problems.

[0006] An atomizing device, the atomizing device comprising:

[0007] A first support structure is provided with a first airflow channel and a first connecting part, and a first airflow cavity is opened in the first airflow channel.

[0009] An elastic seal is provided, wherein a third airflow cavity is provided within the elastic seal, and the elastic seal is embedded in the second support structure;

[0010] When the first connecting part and the second connecting part are detachably fastened together, the bottom of the first airflow channel abuts against the side of the elastic seal near the first support structure, the first airflow cavity and the third airflow cavity are connected, and the connecting part of the first airflow channel and the elastic seal seals the connection between the first airflow cavity and the third airflow cavity.

[0040] See appendix Figure 1 To be continued Figure 7 As shown, this application provides an atomizing device, which includes a first support structure 20, a second support structure 30, and an elastic sealing element 70.

[0041] The first support structure 20 is provided with a first airflow channel 200 and a first connecting part 21, and a first airflow cavity 201 is formed within the first airflow channel 200. The second support structure 30 is provided with a second connecting part 32 adapted to the first connecting part 21, and the second connecting part 32 is detachably fastened to the first connecting part 21. A third airflow cavity 71 is formed within the elastic seal 70, and the elastic seal 70 is embedded in the second support structure 30. When the first connecting part 21 and the second connecting part 32 are detachably fastened, the bottom of the first airflow channel 200 abuts against the side of the elastic seal 70 near the first support structure 20, the first airflow cavity 201 and the third airflow cavity 71 are connected, and the connection between the first airflow channel 200 and the elastic seal 70 seals the connection between the first airflow cavity 201 and the third airflow cavity 71.

[0042] Specifically, after the first support structure 20 is connected to the second support structure 30 via the first connecting portion 21 and the second connecting portion 32, the first support structure 20 and the second support structure 30 enclose a first mounting space for mounting the battery 40 of the atomizing device. A second mounting space is formed between the first support structure 20 and the outer casing 10 for mounting the atomizer 50. The first airflow cavity 201 and the second airflow cavity 301 form an airflow channel. In this embodiment, the first support structure 20 and the second support structure 30 are detachably configured to facilitate the assembly of the battery 40 within the first mounting space. In some embodiments, the first support structure 20 includes a first mounting bracket, and the second support structure 30 includes a second mounting bracket, with the first mounting bracket positioned on top of the second mounting bracket. Understandably, when the atomizing device is working, air passes through the airflow channel and the atomizer 50, causing the atomized aerosol to flow and be inhaled by the user through the mouthpiece 60. When the sealing performance of the airflow channel is poor, on the one hand, the atomizer 50 will atomize the aerosol poorly, meaning that the airflow entering the atomizer 50 is difficult to control, which may result in the aerosol not being fully atomized; on the other hand, the poor sealing performance of the airflow channel will cause abnormal suction resistance of the atomizing device, thereby reducing the user experience; at the same time, the poor sealing performance of the airflow channel will also cause turbulence in the airflow channel, thereby increasing the noise of the atomizing device and affecting the user experience.

[0043] In existing atomizing devices, to facilitate the assembly of the battery 40 within the first mounting space, the first support structure 20 and the second support structure 30 are typically separate units. This results in a gap between the first airflow cavity 201 of the first support structure 20 and the second support structure 30, allowing some gas to enter the airflow channel through this gap, ultimately reducing the sealing performance of the airflow channel. One existing solution to this problem is to install an elastic seal 70 at the connection between the first airflow channel 200 and the second support structure 30, thereby improving the sealing effect of the airflow channel. However, this solution has a problem: during assembly, the first airflow channel 200 needs to be inserted into the third airflow cavity 71 of the elastic seal 70. However, during assembly, due to the lack of positioning between the elastic seal 70 and the outer wall of the first airflow channel 200, it is difficult to assemble successfully in one go, leading to assembly difficulties, wasting time and effort, and potentially damaging the elastic seal 70 in severe cases.

[0044] Compared to the prior art, this embodiment provides a first connecting part 21 on the first support structure 20 and a second connecting part 32 on the second support structure 30. When the first connecting part 21 and the second connecting part 32 are connected, the first airflow channel 200 abuts against the side of the elastic seal 70 near the first support structure 20. That is, when the first connecting part 21 and the second connecting part 32 are connected, the first airflow channel 200 on the first support structure 20 can be automatically positioned and abut against the side of the elastic seal 70 near the first support structure 20. At this time, the elastic seal 70 seals between the first airflow cavity 201 and the second support structure 30. The structure of this embodiment can quickly assemble the elastic seal 70 and the first support structure 20, thereby avoiding the problem of difficult assembly of the elastic seal 70 and the first support structure 20, and improving the sealing performance between the first airflow channel 200 and the second support structure 30.

[0045] Furthermore, the second support structure is provided with a mounting base 311, and a second airflow cavity 301 is provided inside the mounting base 311, with the elastic seal 70 embedded in the second airflow cavity 301.

[0046] Specifically, when assembling the elastic seal 70, the first support structure 20, and the second support structure 30, the elastic seal 70 is first installed on the mounting base 311, and then the elastic seal 70 is embedded in the second airflow cavity 301. At this time, the elastic seal 70 is fixed in the second airflow cavity 301. Then, the first connecting part 21 of the first support structure 20 is connected to the second connecting part 32 of the second support structure 30. At this time, the first airflow channel 200 abuts against the side of the elastic seal 70 near the first support structure 20, and the first airflow cavity 201 communicates with the third airflow cavity 71. That is to say, after the first connecting part 21 is connected to the second connecting part 32, the first airflow channel 200 needs to penetrate into the second airflow cavity 301 of the mounting base 311 and finally abut against the outer surface of the elastic seal 70. The mounting base 311 restricts the position of the elastic seal 70 on the one hand, and provides a positioning effect for the first airflow channel 200 on the other hand.

[0047] To prevent excessive pressure exerted by the first airflow channel 200 on the elastic seal 70, which could cause the elastic seal 70 to detach from the second airflow cavity 301, therefore, in this embodiment, as shown in the attached... Figure 4 As shown, the first airflow channel 200 includes an inner recessed section 203 and an outer expansion section 202 connected to each other at one end near the second support structure 30. The bottom of the inner recessed section 203 abuts against the side of the elastic seal 70 near the first support structure 20, and the bottom of the outer expansion section 202 abuts against the side of the mounting base 311 near the first support structure 20.

[0048] Understandably, after the first support structure 20 and the second support structure 30 are connected, the bottom of the inward section 203 abuts against the side of the elastic seal 70 near the first support structure 20, ensuring the sealing between the elastic seal 70 and the first airflow cavity 201. The bottom of the outward expansion section 202 abuts against the side of the mounting base 311 near the first support structure 20. At this time, the mounting base 311 applies a supporting force to the outward expansion section 202, thereby preventing the inward section 203 from applying too much external force to the elastic seal 70, which would cause the elastic seal 70 to detach from the second airflow cavity 301.

[0049] In addition, the inner wall surface of the second airflow cavity 301 is provided with a flange 3011, which is formed by the inner wall surface of the second airflow cavity 301 protruding along the direction close to the axis of the second airflow cavity 301; a groove 72 adapted to the flange 3011 is provided on the outer peripheral side wall of the elastic seal 70, and the flange 3011 is embedded in the groove 72.

[0050] Specifically, the flange 3011 and the groove 72 improve the connection stability between the elastic seal 70 and the second airflow cavity 301, which to a certain extent prevents the elastic seal 70 from detaching from the second airflow cavity 301 or the first airflow channel 200 from collapsing when the external force applied to the elastic seal 70 of the first airflow channel 200 is too large.

[0051] Furthermore, the atomizing device also includes a housing 10, within which a receiving cavity is provided. A first support structure 20 and a second support structure 30 are disposed within the receiving cavity, and an air inlet 101 is provided on the housing 10. The atomizing device also includes an adjusting component 80, which is disposed between the housing 10 and the second support structure 30. The adjusting component 80 has a first position with the air inlet 101 open and a second position with the air inlet 101 closed.

[0052] Specifically, air from outside the atomizing device enters the accommodating cavity through the air inlet 101, and then sequentially passes through the second airflow cavity 301, the third airflow cavity 71, and the first airflow cavity 201 before entering the atomizer 50. This air then carries the atomized aerosol matrix from the atomizer 50 out of the mouthpiece 60. In this embodiment, the adjusting component 80 is used to adjust the opening and closing of the air inlet 101. When the user needs to use the device, the adjusting component 80 should be moved to the first position to allow air to smoothly enter the atomizer 50 through the airflow channel. When the user does not need to use the device, the adjusting component 80 should be moved to the second position to prevent air from entering the atomizer 50 and affecting the aerosol. Furthermore, when the adjusting component 80 is moved to the second position, the air inlet 101 is closed, making it difficult for the user to apply suction to the aerosol in the gas channel through the mouthpiece 60.

[0053] Furthermore, the adjustment component 80 includes a control part 82 and a blocking part 81. The control part 82 is connected to the blocking part 81, and the blocking part 81 is provided with a first through hole 812. When the control part 82 is driven by an external force to move the blocking part 81 to the first position, the first through hole 812 is connected to the air inlet 101 and the third airflow cavity 71 respectively. When the control part 82 is driven by an external force to move the blocking part 81 to the second position, the first through hole 812 is separated from the air inlet 101 and the third airflow cavity 71 respectively.

[0054] In some embodiments, the control unit 82 includes an operating member connected to the side of the blocking part 81 away from the second support structure 30, and the operating member extends to the outside of the outer casing 10. The blocking part 81 includes a baffle with a first through hole 812. When it is necessary to close the air inlet 101, an external force is applied to the operating member, causing the operating member to move the baffle to a second position, at which point the air inlet 101 is blocked by the baffle. When it is necessary to open the air inlet 101, an external force is applied to the operating member, causing the operating member to move the baffle to a first position, at which point the air inlet 101 is connected to the first through hole 812, and external air can enter the air inlet 101 and the third airflow cavity 71 through the first through hole 812.

[0055] In some embodiments, the blocking part 81 is provided with a locking protrusion, and the second support structure 30 is provided with a sliding groove. The locking protrusion is engaged in the sliding groove, thereby enabling the blocking part 81 to be fixed on the second support structure 30 and to switch between the first position and the second position.

[0056] In some embodiments, the first through holes 812 include a plurality of holes, which are spaced apart on the blocking portion 81. It is understood that, since there are multiple first through holes 812, the number of first through holes 812 communicating with the air inlet 101 affects the airflow rate into the airflow channel. In a specific embodiment, as the baffle moves from the first position to the second position, the number of first through holes 812 communicating with the air inlet 101 gradually increases. This configuration facilitates automatic adjustment of the airflow rate in the airflow channel by the user, allowing the user to adjust the atomization degree of the aerosol according to their preference.

[0057] Furthermore, the elastic seal 70 is provided with an annular protrusion 73, which protrudes towards the side near the blocking part 81. The third airflow cavity 71 passes through the middle of the annular protrusion 73, and the annular protrusion 73 abuts against the blocking part 81.

[0058] Specifically, in this embodiment, the annular protrusion 73 can fully contact the baffle and, to a certain extent, prevent a gap from existing between the baffle and the annular protrusion 73 after the baffle is tilted, thereby affecting the sealing performance between the elastic seal 70 and the baffle. Furthermore, when the baffle is in the second position, the annular protrusion 73 abuts against the blocking portion 81, and the elastic seal 70 and the baffle are in a sealed state. When the baffle is in the first position, the third airflow cavity 71, the first through hole 812, and the air inlet 101 are connected.

[0059] See appendix Figure 2As shown, the atomizing device also includes a control board 90, which is disposed between the first support structure 20 and the second support structure 30. A power switch 91 is provided on the control board 90. The power switch 91 has a third position for turning on the power of the atomizing device and a fourth position for turning off the power of the atomizing device. An adjustment component 80 is connected to the power switch 91. When the adjustment component 80 switches between the first position and the second position, the adjustment component 80 drives the power switch 91 to switch between the third position and the fourth position.

[0060] Specifically, the control board 90 is electrically connected to the battery 40, and the atomizer 50 is electrically connected to the control board 90. When the power switch 91 is in the third position, the atomizer 50 receives current, thus atomizing the aerosol. When the power switch 91 is in the fourth position, the atomizer 50 receives no current, and the aerosol in the atomizing device will not atomize. Furthermore, the adjustment component 80 is connected to the power switch 91. When the adjustment component 80 moves to the first position, it drives the power switch 91 to the third position, i.e., when the air inlet 101 is open, the atomizer 50 receives current to facilitate aerosol atomization. When the adjustment component 80 moves to the second position, it drives the power switch 91 to the fourth position, i.e., when the air inlet 101 is closed, the atomizer 50 receives no current, preventing aerosol atomization and reducing energy consumption of the battery 40.

[0061] In some embodiments, a limiting groove 811 is provided on the side of the blocking part 81 near the second support structure 30, and the power switch 91 passes through the limiting groove 811. When the blocking part 81 moves, the inner wall of the limiting groove 811 applies an external force to the power switch 91, thereby causing the power switch 91 to switch between the third position and the fourth position.

[0062] Furthermore, the resilient seal 70 includes at least one of a silicone resilient seal, a nitrile rubber resilient seal, a polytetrafluoroethylene resilient seal, and a fluororubber resilient seal.

[0063] In this embodiment, thanks to the good wear resistance and elasticity of the silicone elastic seal, nitrile rubber elastic seal, polytetrafluoroethylene elastic seal and fluororubber elastic seal, when the elastic seal 70 is subjected to pressure by the first airflow channel 200, the elastic seal 70 can tightly adhere to the bottom of the first airflow channel 200, thereby improving the sealing effect between the outer wall surface of the first through hole 812 and the outer surface of the elastic seal 70. At the same time, the good wear resistance improves the service life of the elastic seal 70.

[0064] Furthermore, one of the first connecting part 21 and the second connecting part 32 is provided with a buckle 211, and the other is provided with a slot 321. The first connecting part 21 and the second connecting part 32 are detachably fastened together by the buckle 211 and the slot 321.

[0065] In one specific embodiment, the first connecting part 21 is a buckle 211, and the second connecting part 32 is a slot 321. The buckle 211 is fastened into the slot 321, thereby fixing the first support structure 20 and the second support structure 30. In some embodiments, there are multiple slots 321, which are spaced apart on the second support structure 30. There are also multiple buckles 211, which are spaced apart on the first support structure 20. Each buckle 211 corresponds to each slot 321, thereby improving the connection stability between the first support structure 20 and the second support structure 30.

[0066] In summary, the atomizing device of this application is provided with a first connecting portion 21 and a second connecting portion 32 on the first support structure 20 and the second support structure 30, respectively. When the first connecting portion 21 and the second connecting portion 32 are connected, the first airflow channel 200 abuts against the side of the elastic seal 70 near the first support structure 20, and the elastic seal 70 seals the connection between the first airflow cavity 201 and the third airflow cavity 71, thereby improving the ease of assembly of the first support structure 20, the second support structure 30, and the elastic seal 70, as well as the sealing performance of the overall structure. In this application, the elastic seal 70 is embedded in the second airflow cavity 301, and a flange 3011 is provided in the second airflow cavity 301. A groove 72 adapted to the flange 3011 is opened on the outer periphery of the elastic seal 70, and the flange 3011 passes through the groove 72, thereby preventing the elastic seal 70 from being dislodged from the second airflow cavity 301 due to excessive pressure applied by the first airflow channel 200. The atomizing device of this application also includes an adjustment component 80, which has a first position with the air inlet 101 open and a second position with the air inlet 101 closed to adapt to different working states of the atomizing device. Furthermore, the elastic seal 70 of this application has an annular protrusion 73 on the side near the blocking portion 81. The annular protrusion 73 abuts against the blocking portion 81 and is used to improve the sealing performance between the elastic seal 70 and the blocking portion 81, preventing the blocking portion 81 from shifting and causing a gap between the elastic seal 70 and the blocking portion 81.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
