[0045] This embodiment provides a sealing member fixing structure, including a mainboard bracket 1, an airway sealing member 2, and an airway pressing member 3. Figure 1-Figure 3 , illustrating the mainboard bracket 1, the airway seal 2 and the airway pressure piece 3.
[0046] See Figure 2 A mounting groove 101 is formed on the mainboard bracket 1 , the airway seal 2 is arranged in the mounting groove 101 , and an airflow cavity 201 is formed in the airway seal 2 .
[0047] See Figure 3 An air passage 103 is formed on the mainboard bracket 1. The air passage 103 is arranged below the mounting slot 101 and is connected to the airflow cavity 201 in the airway seal 2. In the prior art, an airflow detection device 6 is provided at the free end of the air passage 103. When air flows through the airflow detection device 6 to the air passage 103, the airflow in the air passage 103 may flow into the airway seal. However, due to the lack of a stable structure to fix the airway seal in the mounting slot 101, when air flows toward the airway seal, the airway seal may change position relative to the mounting slot 101, causing part of the airflow to flow between the airway seal and the slot wall of the mounting slot 101, resulting in air leakage.
[0048] In this embodiment, the airway seal 2 and the mainboard bracket 1 are connected by the airway pressing piece 3, and the airway seal 2 is pressed and fixed to the mainboard bracket 1 by the airway pressing piece 3, so that when the airflow in the air channel 103 flows to the airflow cavity 201 of the airway seal 2, the airway seal 2 can still be stably fixed on the mainboard bracket 1, avoiding the situation in the prior art where the airflow blows the airway seal, causing air leakage between the airway seal and the groove wall of the installation groove 101, thereby solving the technical problem in the prior art that the installation method of the airway seal on the electronic atomization device easily leads to the risk of air leakage.
[0049] As mentioned above, the airway pressing piece 3 presses the airway sealing piece 2 onto the mainboard bracket 1. In one embodiment, see Figure 4 and Figure 5 The airway pressure piece 3 includes a pressing plate 301 and a connecting portion 302 , and the connecting portion 302 is connected to the pressing plate 301 .
[0050] Preferably, the pressing plate 301 and the connecting portion 302 are an integrally formed structure; the material of the airway sealing member 2 can be selected to be a hard plastic material.
[0051] In this embodiment, the number of connecting portions 302 is more than one, that is, the pressing plate 301 may be provided with one connecting portion 302, or two, three, etc. connecting portions 302 may be provided. A reasonable number of connecting portions 302 may be provided on the pressing plate 301 according to the area of the pressing plate 301.
[0052] See Figure 6 and Figure 7 The airway seal 2 includes a sealing bottom 202 and a sealing side 203 . The sealing side 203 is arranged along the circumferential edge of the sealing bottom 202 and connected to the sealing bottom 202 . The sealing bottom 202 and the sealing side 203 form an airflow cavity 201 .
[0053] See Figure 1 and Figure 3 The airway seal 2 is disposed within the mounting groove 101 of the mainboard bracket 1. The size and shape of the airway seal 2 match the size and shape of the mounting groove 101. Specifically, the shape of the sealing bottom 202 is the same as or substantially the same as the shape of the groove bottom surface of the mounting groove 101, and the shape of the sealing side portion 203 is the same as or substantially the same as the shape of the circumferential side wall of the mounting groove 101. When the airway seal 2 is disposed within the mounting groove 101, the sealing bottom 202 preferably abuts the groove bottom surface of the mounting groove 101, and the sealing side portion 203 abuts the circumferential side wall of the mounting groove 101. The airway seal 2 can be made of silicone, which is soft and easily abuts the mounting groove 101.
[0054] See Figure 6 , a socket 2021 is provided on the sealing bottom 202. When the airway seal 2 is pressed and fixed on the mainboard bracket 1 through the airway pressing piece 3, please refer to Figure 3 The pressing plate 301 of the airway pressure piece 3 fits with the sealing bottom 202 , and the connecting portion 302 passes through the socket 2021 and is fixed on the mainboard bracket 1 , thereby pressing the airway pressure piece 3 onto the mainboard bracket 1 .
[0055] The structure of the airway pressing piece 3 provided in this embodiment can not only stably fix the airway sealing piece 2 on the mainboard bracket 1, but also has a simple structure.
[0056] Regarding the connection part 302 being fixed on the motherboard bracket 1, in one example, a bracket socket 102 is provided on the motherboard bracket 1, and the connection part 302 is tightly fitted with the bracket socket 102; or, in another embodiment, the connection part 302 is an elastic clip, and the connection part 302 passes through the motherboard bracket 1 and is clipped onto the motherboard bracket 1.
[0057] See Figure 2 A bracket insertion hole 102 is provided on the bottom surface of the mounting groove 101 , and the connecting portion 302 passes through the socket 2021 on the airway pressure piece 3 and is inserted into the bracket insertion hole 102 .
[0058] In this embodiment, by setting the connecting portion 302 as an elastic snap-fit structure, the airway pressure piece 3 can be quickly fixed on the mainboard bracket 1.
[0059] In the example where the connecting portion 302 is an elastic buckle, in one embodiment, see Figure 4 and Figure 5 The connecting portion 302 includes a first snap-fit portion 3021 and a second snap-fit portion 3022 . The first snap-fit portion 3021 and the second snap-fit portion 3022 are spaced apart from each other and both are connected to one side of the pressing plate 301 .
[0060] See Figure 4 and Figure 5 , illustrating the first snap portion 3021 and the second snap portion 3022. When the airway pressure piece 3 is installed on the mainboard bracket 1, the first snap portion 3021 and the second snap portion 3022 are inserted into the socket 2021 on the airway seal 2 and the bracket socket 102 on the bracket socket 102 in sequence. When the first snap portion 3021 and the second snap portion 3022 are inserted into the bracket socket 102, the first snap portion 3021 and the second snap portion 3022 are deformed in the direction of approaching each other. When the first snap portion 3021 and the second snap portion 3022 are inserted into place, the first snap portion 3021 and the second snap portion 3022 move in the direction of resetting, thereby causing the connecting portion 302 to be snapped and fixed to the mainboard bracket 1.
[0061] The structure of the connecting portion 302 provided in this embodiment is simple and easy to manufacture.
[0062] In one embodiment, there are more than two connecting parts 302 , and the number of the sockets 2021 on the airway sealing element 2 is consistent with the number of the connecting parts 302 , and the connecting parts 302 are inserted into the corresponding sockets 2021 .
[0063] See Figure 5 , schematically showing that two connecting parts 302 are provided on the pressing plate 301, and the two connecting parts 302 are spaced apart along the length direction of the pressing plate 301. Figure 6The airway seal 2 is provided with two sockets 2021, and the mainboard bracket 1 is provided with two bracket sockets 102. The connecting parts 302 are respectively inserted into the corresponding sockets 2021 and bracket sockets 102. That is, in this embodiment, it is preferred to provide two connecting parts 302 on the pressing plate 301.
[0064] For each connecting portion 302 on the pressing plate 301 , it is preferred that each connecting portion 302 has the same structure, that is, each connecting portion 302 includes a first buckle portion 3021 and a second buckle portion 3022 .
[0065] In this embodiment, by providing two or more connecting portions 302 , the airway pressure piece 3 can be stably fixed on the mainboard bracket 1 .
[0066] In an embodiment, based on the example that the connecting portion 302 includes a first buckle portion 3021 and a second buckle portion 3022, see Figure 4 and Figure 5 An air guide column 303 is provided on the side of the pressing plate 301 facing away from the bottom surface of the installation groove 101, and a through hole 3031 is provided on the air guide column 303. An air hole 3011 is provided on the pressing plate 301, and the air hole 3011 is located between the first snap portion 3021 and the second snap portion 3022 of one of the connecting parts 302, and the air hole 3011 is connected to the through hole 3031 and the corresponding socket 2021.
[0067] See Figure 4 , schematically shows the air guide column 303 provided on the pressing plate 301 , and the air guide column 303 and the connecting portion 302 are respectively provided on two opposite sides of the pressing plate 301 . Figure 4 FIG. 3 schematically shows that the air guide column 303 is provided with a through hole 3031. Figure 5 Schematically shows the air hole 3011 provided on the pressing plate 301 , and the through hole 3031 is connected to the air hole 3011 .
[0068] When the airway seal 2 is fixed to the mainboard bracket 1 through the airway pressure piece 3, the airflow in the air channel 103 on the mainboard bracket 1 can flow to the airflow cavity 201 of the airway seal 2 through the spacing space between the first snap portion 3021 and the second snap portion 3022 and the air hole 3011 and the through hole 3031.
[0069] When there are more than two connecting parts 302, the air hole 3011 is located between the first buckle part 3021 and the second buckle part 3022 of one of the connecting parts 302. Figure 5 , illustrating that the air hole 3011 is located between the first snap portion 3021 and the second snap portion 3022 on the right side.
[0070] In this embodiment, the air hole 3011 is arranged between the first snap portion 3021 and the second snap portion 3022 of one of the connecting portions 302, so that the air flow in the air channel 103 on the mainboard bracket 1 can flow to the air hole 3011 through the bracket socket 102 and the socket 2021, without the need to add new holes connected to the air hole 3011 on the mainboard bracket 1 and the airway seal 2.
[0071] In one embodiment, a bottom annular protrusion 2022 is provided on the side of the sealing bottom 202 that contacts the bottom surface of the mounting groove 101. The bottom annular protrusion 2022 surrounds the socket 2021 and each socket 2021 corresponds to at least one bottom annular protrusion 2022. Figure 7 , schematically shows the bottom annular protrusion 2022, which is arranged around the socket 2021. Preferably, the center of the bottom annular protrusion 2022 is located on the axis of the socket 2021.
[0072] When the airway sealing member 2 is pressed and fixed on the mainboard bracket 1 by the airway pressing member 3 , the bottom annular protrusion 2022 is squeezed and deformed, so as to better seal the position of the socket 2021 .
[0073] In the example where there are more than two sockets 2021 on the airway seal 2, each socket 2021 has a corresponding bottom annular protrusion 2022. Figure 7 , schematically shows two sockets 2021 on the airway seal 2, each socket 2021 corresponding to an annular protrusion 2022.
[0074] Each socket 2021 corresponds to at least one bottom annular protrusion 2022, see Figure 7 , illustrating that each socket 2021 corresponds to a bottom annular protrusion 2022, or each socket 2021 can also correspond to two bottom annular protrusions 2022, and the two bottom annular protrusions 2022 are concentrically arranged and have different radii.
[0075] In this embodiment, by providing the bottom annular protrusion 2022, the position of the socket 2021 is better sealed to further prevent air leakage.
[0076] The above embodiment describes the bottom annular protrusion 2022 as being disposed around the sockets 2021, meaning that each socket 2021 mates with a corresponding bottom annular protrusion 2022. Regarding the bottom annular protrusion 2022, in another embodiment, the bottom annular protrusion 2022 is disposed on the side of the sealing bottom 202 that contacts the bottom surface of the mounting groove 101, and each socket 2021 is located inwardly of the bottom annular protrusion 2022 within the sealing bottom 202. In this case, even if there are more than two sockets 2021, the number of bottom annular protrusions 2022 can be set to one. Of course, more than two bottom annular protrusions 202 can also be provided, with each bottom annular protrusion 2022 being nested in sequence.
[0077] Regarding the bottom annular protrusion 2022, in another embodiment, a bottom annular protrusion 2022 is provided on the side where the sealing bottom 202 is in contact with the bottom surface of the mounting groove 101. There are multiple bottom annular protrusions 2022, such as Figure 7 The bottom annular protrusion 2022 shown surrounds the corresponding socket 2021, and there is a bottom annular protrusion 2022 that surrounds each socket 2021. In this embodiment, by providing multiple bottom annular protrusions 2022, the socket 2021 position is better sealed to further prevent air leakage.
[0078] In one embodiment, a top annular protrusion 2023 is provided on the side of the sealing bottom 202 that contacts the pressing plate 301 , and each socket 2021 is located on the inner side of the top annular protrusion 2023 on the sealing bottom 202 .
[0079] See Figure 6 , illustrating the top annular protrusion 2023 , which matches the shape of the sealing bottom 202 , and the two sockets 2021 are both located on the inner side of the top annular protrusion 2023 .
[0080] When the airway sealing member 2 is pressed and fixed on the mainboard bracket 1 by the airway pressing member 3 , the top annular protrusion 2023 is squeezed and deformed, so as to better achieve sealing with the pressing plate 301 .
[0081] Regarding the number of the top annular protrusion 2023, which can be set to one, see Figure 6 , schematically shows a top annular protrusion 2023, or the number of the top annular protrusions 2023 can be set to more than two, and the top annular protrusions 2023 are arranged in sequence.
[0082] In this embodiment, by providing the top annular protrusion 2023 , better sealing with the pressing plate 301 can be achieved, further preventing air leakage.
[0083] The above embodiment records that the position of each socket 2021 in the sealing bottom 202 is located on the inner side of the top annular protrusion 2023. Regarding the top annular protrusion 2023, in another embodiment, a top annular protrusion 2023 is provided on the side of the sealing bottom 202 that is in contact with the pressing plate 301. The top annular protrusion 2023 is arranged around the socket 2021 and each socket 2021 corresponds to at least one top annular protrusion 2023.
[0084] Regarding the top annular protrusion 2023, in another embodiment, a top annular protrusion 2023 is provided on the side where the sealing bottom 202 is in contact with the pressing plate 301. There are multiple top annular protrusions 2023, including a top annular protrusion 2023 surrounding the corresponding socket 2021, and a top annular protrusion 2023 as shown in FIG. Figure 6 As shown, each socket 2021 is arranged around the top annular protrusion 2023 on its inner side. In this embodiment, by providing multiple top annular protrusions 2023, a better seal with the pressing plate 301 can be achieved, further preventing the occurrence of air leakage.
[0085] In one embodiment, one end of the sealing side portion 203 away from the sealing bottom 202 extends away from the center of the airflow cavity 201 to form a flange structure 204, which is used to seal with the base 4 above the mainboard bracket 1.
[0086] See Figure 6 and Figure 7 , showing the flange structure 204, see Figure 9 , illustrating the base 4 set on the mainboard bracket 1, that is, when the base 4 is set above the mainboard bracket 1, the flange structure 204 is squeezed between the mainboard bracket 1 and the base 4, thereby realizing the sealing fit between the airway seal 2 and the base 4.
[0087] In this embodiment, a flange structure 204 is formed on the airway seal 2 to facilitate the sealing cooperation between the airway seal 2 and the base 4, thereby preventing the gas in the airway seal 2 from leaking through the gap between the airway seal 2 and the base 4.
[0088] See Figure 8-Figure 9 , Figure 8 This is a schematic diagram of the structure of the electronic atomization device provided in an embodiment of the present application. Figure 9 This is a schematic cross-sectional view of part of the structure of the electronic atomization device provided in an embodiment of the present application.
[0089] This embodiment provides an electronic atomization device, including a base 4, a mainboard 5, and a sealing member fixing structure provided in any of the above embodiments. Figure 9 , showing the base 4 and the main board 5.
