Description

Technical Field

[0001] This application belongs to the field of atomizing device technology, and particularly relates to an airway seal, a battery rod, and an atomizing device. Background Technology

[0002] An atomizing device is a device used to heat an aerosol matrix to atomize it into an aerosol. An atomizing device consists of a battery rod and an atomizer. The atomizer is installed within the housing of the battery rod. When the atomizer's mouthpiece is inhaled, a negative pressure is created between the bottom of the atomizer and the battery rod. This negative pressure is transmitted to a pressure detection device on the battery rod. Because the atomizer and battery rod must have a clearance fit—otherwise, the atomizer cannot be easily replaced—these assembly gaps may result in insufficient negative pressure between the bottom of the atomizer and the battery rod when inhaling, preventing the pressure detection device from being triggered and thus affecting the sensitivity of the atomizing device. Utility Model Content

[0003] The purpose of this application is to provide an airway seal, a battery rod, and an atomizing device to solve the technical problem in the prior art where insufficient negative pressure may occur when inhaling the mouthpiece of the atomizer due to the gap between the atomizer and the battery rod, preventing the pressure sensor from being triggered.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A first aspect of this application provides an air passage seal for mounting in a recess on a battery rod, the air passage seal comprising a seal bottom and a seal side, wherein:

[0006] The side of the seal is connected to the circumferential edge of the bottom of the seal so that the two form a gas cavity; the bottom of the seal is provided with an air hole, and the end of the side of the seal away from the bottom of the seal is flared to be used for sealing with the bottom of the atomizer.

[0007] In some implementations, the thickness of the flared region on the side of the seal decreases along the direction away from the bottom of the seal.

[0008] In some implementations, two air holes are provided on the bottom of the seal, and the two air holes are spaced apart along the length direction of the bottom of the seal; the air passage seal has a symmetrical structure, and the axis of symmetry of the air passage seal is parallel to the width direction of the bottom of the seal.

[0009] In some implementations, the seal further includes a limiting portion disposed on the outer circumferential side of the side portion of the seal, wherein when the airway seal is located in the recessed groove, the limiting portion is located outside the recessed groove.

[0010] In some implementations, the limiting portion includes a limiting circumferential portion and a limiting extension portion. The limiting circumferential portion is connected to the outer circumferential side of the sealing member side, and one end of the limiting extension portion is connected to the limiting circumferential portion.

[0011] In some implementations, there are multiple limiting extensions, and the multiple limiting extensions are symmetrically arranged on the limiting circumferential portion.

[0012] In some implementations, the bottom and / or side of the seal engage with the recessed groove in a sealing fit.

[0013] A second aspect of this application provides a battery rod, including a battery bracket and an airway seal provided by any of the above-described technical solutions, wherein: a recessed groove is provided on the end face of one end of the battery bracket, and a detection airway communicating with the recessed groove is formed on the battery bracket; the airway seal is installed in the recessed groove, and the airway seal includes a seal bottom and a seal side, wherein the seal side protrudes from the recessed groove on the side opposite to the seal bottom for sealing cooperation with an atomizer.

[0014] In some implementations, the battery rod further includes an anti-detachment component, and the anti-detachment component is fixed to one end of the battery bracket where the recessed groove is located. The anti-detachment component is provided with a clearance hole to avoid the side of the sealing component. The air passage sealing component further includes a limiting part, which is located on the outer circumferential side of the side of the sealing component. The limiting part is located outside the recessed groove and is limited between the anti-detachment component and the battery bracket.

[0015] A third aspect of this application provides an atomizing device, including an atomizer and a battery rod provided by any of the above technical solutions. One end of the battery rod has a receiving cavity, the atomizer is inserted into the receiving cavity and connected to the battery rod, the bottom of the atomizer is sealed to an air passage seal on the battery rod, and the air inlet at the bottom of the atomizer is connected to the gas chamber of the air passage seal.

[0016] The beneficial effects of this application are as follows: When the airway seal provided in the embodiment of this application is set in the recessed groove on the battery bracket, the flared area of ​​the airway seal can seal and cooperate with the bottom of the atomizer, so that the air inlet at the bottom of the atomizer is only connected to the gas chamber in the airway seal and not connected to the assembly gap between the atomizer and the battery rod, making it easy to trigger the air pressure detection device when inhaling the atomizing device.

[0052] Please see Figures 1-2 , Figure 1 This is a schematic diagram of the structure of the atomizing device 100 provided in the embodiments of this application. Figure 2This is an exploded view of the atomizing device 100 provided in an embodiment of this application. It is worth noting that, for the convenience of the following description, the following orientations are defined: the atomizing device 100 can be calibrated using the following three mutually perpendicular axes: the X-axis, the Y-axis, and the Z-axis. Wherein, as...

[0053] Please see Figure 1 and Figure 2 The atomizing device 100 provided in this application embodiment includes an atomizer 20 and a battery rod 10. The battery rod 10 is connected to the atomizer 20 and can provide power to the atomizer 20.

[0054] The atomizer 20 has a cavity for storing aerosol matrix, and the atomizer 20 includes an atomizing core. The atomizing core is electrically connected to the battery 19 in the battery rod 10. When the atomizing core is in working condition (i.e., current flows through the atomizing core), the atomizing core can heat the aerosol matrix that has penetrated into the atomizing core and cause it to evaporate. When the user inhales through the mouthpiece 21 of the atomizer 20, there is airflow in the atomizing core. The evaporated aerosol matrix forms mist under the condensation effect of the airflow. The mist can flow with the airflow to the mouthpiece 21.

[0055] In one example, the atomizer 20 is detachably connected to the battery rod 10, for example, the atomizer 20 can be detachably connected to the battery rod 10 by magnetic attraction.

[0056] Please see Figures 3-5 , Figure 3 This is a schematic diagram of the structure of the battery rod 10 provided in an embodiment of this application. Figure 4 This is an exploded view of the battery rod 10 provided in an embodiment of this application. Figure 5 An exploded view of the outer casing 13 provided in an embodiment of this application.

[0057] Please see Figure 3 The battery rod 10 has a receiving cavity 14 formed at one end along its length, through which the atomizer 20 can be inserted into the battery rod 10. (See also...) Figure 3 The diagram shows that an electrode 16 is provided on the bottom surface of the cavity 14, and the electrode 16 is used to electrically connect with the atomizer 20.

[0058] Please see Figure 4 The battery rod 10 provided in this application embodiment includes a housing 13 and a battery bracket 11, with the housing 13 sleeved on the outside of the battery bracket 11.

[0059] Specifically, the inner side of the outer shell 13 includes a first region and a second region, which are arranged sequentially along the length of the outer shell 13. The battery bracket 11 is located in the second region, and one end of the battery bracket 11 and the space enclosed by the first region form a receiving cavity 14 for placing the atomizer 20.

[0060] Please see Figure 4 The diagram illustrates the battery 19 and motherboard 18 mounted on the battery bracket 11. In one example, the battery 19 and motherboard 18 are arranged side by side. A display bracket is provided on the side of the motherboard 18 away from the battery 19. The display bracket is connected to the battery bracket 11. A flexible display screen 110 is provided on the side of the display bracket away from the motherboard 18.

[0061] In one example, the battery holder 11 is snapped into the housing 13.

[0062] In one example, see 4 and Figure 5 The outer casing 13 includes an outer casing body 131, a decorative part 132, and a lens part 133. The outer casing body 131 is cylindrical. The decorative part 132 and the lens part 133 are both bent into a U-shape along the thickness direction of the battery rod 10. The decorative part 132 and the lens part 133 are disposed opposite to each other on the outer casing body 131 along the width direction of the battery rod 10. The decorative part 132 is disposed on the outer side of the outer casing body 131. The outer casing body 131 is provided with a mounting slot 1311. The lens part 133 is located in the mounting slot 1311 and faces the flexible display screen 110.

[0063] In one example, the decorative part 132 is made of polyurethane synthetic leather and is attached to the outer shell body 131.

[0064] In one example, the lens portion 133 is snapped onto the housing body 131.

[0065] In one example, see Figure 5 The outer casing 13 also includes a shielding part 134. A bottom groove is formed at the bottom of the outer casing body 131 (i.e., the end of the outer casing body 131 away from the atomizer 20). The shielding part 134 is disposed in the bottom groove and can shield the connector connecting the outer casing body 131, the lens part 133 and the battery bracket 11.

[0066] In one example, the shielding part 134 is made of polyurethane synthetic leather and is attached to the outer shell body 131.

[0067] Please see Figures 6-10 , Figure 6 This is a schematic diagram of the structure of the battery holder 11 and the air passage seal 12 provided in the embodiments of this application. Figure 7This is an exploded view of the battery holder 11 and the airway seal 12 provided in the embodiments of this application. Figure 8 Schematic diagram of the structure of the airway seal 12 provided in the embodiments of this application Figure 1 , Figure 9 Schematic diagram of the structure of the airway seal 12 provided in the embodiments of this application Figure 2 , Figure 10 This is a partial cross-sectional view of the battery holder 11 and the air passage seal 12 provided in the embodiments of this application.

[0068] Please see Figure 7 A recessed groove 111 is formed on the end face of one end of the battery holder 11. The recessed groove 111 is used to house the air passage seal 12. The shape of the air passage seal 12 matches that of the recessed groove 111. Please refer to [link to relevant documentation]. Figure 6 This illustrates that the airway seal 12 is mounted on the battery bracket 11.

[0069] Please see Figure 8 The airway seal 12 includes a seal bottom 121 and a seal side 122. The seal side 122 is connected to the circumferential edge of the seal bottom 121 so that the two form a gas cavity 123. The seal bottom 121 corresponds to the bottom surface of the recessed groove 111, and the seal side 122 corresponds to the side surface of the recessed groove 111.

[0070] Please see Figure 9 The bottom 121 of the seal is provided with an air hole 124, please refer to Figure 10 The vent 124 is connected to the detection air passage 112 on the battery holder 11. Please refer to... Figure 10 One end of the detection air passage 112 extends to the bottom surface of the recessed groove 111, and the other end of the detection air passage 112 faces the air pressure detection device on the main board 18 of the battery 19. Please refer to... Figure 7 The end of the detection airway 112 that opens to the bottom of the recessed groove 111 is the first end 1121 of the airway, and the first end 1121 of the airway is connected to the air hole 124 on the airway seal 12.

[0071] In one example, the bottom 121 of the seal is sealed to the bottom surface of the recessed groove 111, and / or the side 122 of the seal is sealed to the side surface of the recessed groove 111, so that air in the detection air passage 112 can flow through the air hole 124 to the gas chamber 123 in the air passage seal 12, preventing air in the detection air passage 112 from flowing out through the gap between the air passage seal 12 and the recessed groove 111.

[0072] In one example, the airway seal 12 is made of silicone.

[0073] In this embodiment of the application, please refer to Figure 8The end of the sealing side 122 facing away from the bottom 121 of the sealing element is flared, and the end of the sealing side 122 facing away from the bottom 121 of the sealing element extends out of the recessed groove 111 for sealing and engaging with the bottom of the atomizer 20. It should be noted that, for ease of description below, the flared area on the sealing side 122 is referred to as the flared area 1221. Please refer to [link to relevant documentation]. Figure 8 This indicates the flared area 1221.

[0074] Please return to the previous page. Figure 2 An air inlet 22 is provided at the bottom of the atomizer 20. When the atomizer 20 is installed on the battery rod 10, the flared area 1221 is squeezed between the battery rod 10 and the bottom of the atomizer 20. The flared area 1221 is arranged around the air inlet 22 so that the interior of the airway seal 12 is connected to the air inlet 22 at the bottom of the atomizer 20.

[0075] When using the atomizing device 100 provided in this application embodiment, when the user inhales through the mouthpiece 21 of the atomizer 20, the air in the detection airway 112 flows through the air hole 124 on the airway seal 12 to the gas chamber 123 in the airway seal 12, and flows into the atomizer 20 through the air inlet 22 at the bottom of the atomizer 20, and is finally discharged through the mouthpiece 21. At this time, a negative pressure state is formed around the air pressure detection device, which can trigger the air pressure detection device.

[0076] In existing technologies, a groove is usually set on the battery holder of the battery rod that is directly connected to the air intake at the bottom of the atomizer. That is, the groove and the air intake at the bottom of the atomizer are not sealed. Since the atomizer and the battery rod must be fitted with a gap, otherwise the atomizer cannot be replaced smoothly, these assembly gaps may cause insufficient negative pressure between the bottom of the atomizer and the battery rod when inhaling the atomizer, which will prevent the air pressure detection device from being triggered, thus affecting the sensitivity of the atomizer.

[0077] In this embodiment, when the airway seal 12 is placed in the recessed groove 111 on the battery bracket 11, the flared area 1221 of the airway seal 12 can seal with the bottom of the atomizer 20, so that the air inlet 22 at the bottom of the atomizer 20 is only connected to the gas chamber 123 in the airway seal 12 and not connected to the assembly gap between the atomizer 20 and the battery rod 10, making it easy to trigger the air pressure detection device when the atomizing device 100 is inhaled.

[0078] In one embodiment, please refer to Figure 8 An annular protrusion 126 is formed on the circumferential side of the sealing element side 122, and the annular protrusion 126 enables the air passage sealing element 12 to seal against the groove side of the recessed groove 111.

[0079] In one example, the number of annular protrusions 126 on the side 122 of the seal is one or more. For example, the number of annular protrusions 126 on the side 122 of the seal is one; or, the number of annular protrusions 126 on the side 122 of the seal is two or more, and each annular protrusion 126 is arranged sequentially along the depth direction of the gas cavity 123 on the air passage seal 12.

[0080] It is worth noting that, as described in the above embodiment, an annular protrusion 126 is formed on the circumferential side of the sealing member side 122. In other embodiments, an annular protrusion for sealing and engaging with the bottom surface of the recessed groove 111 may also be provided on the bottom 121 of the sealing member, and the annular protrusion is wrapped around the outside of the air hole 124 on the air passage seal 12.

[0081] In one embodiment, please refer to Figure 7 Along the thickness direction of battery rod 10, i.e. Figure 7 In the Y-axis direction, electrode holes 117 are provided on both sides of the recessed groove 111, and the electrodes 16 of the battery rod 10 can be inserted into the electrode holes 117.

[0082] In one embodiment, please refer to Figure 7 Along the width direction of battery rod 10, i.e. Figure 7 In the X-axis direction, magnetic mounting slots 119 are provided on opposite sides of the recessed groove 111. Magnetic components 17 for magnetic attraction with the magnet on the atomizer 20 can be installed in the magnetic mounting slots 119 to achieve a detachable connection between the atomizer 20 and the battery rod 10.

[0083] In one embodiment, please refer to Figure 7 A bracket groove 114 is formed at one end of the battery bracket 11, and several reinforcing ribs 115 are provided on the bottom surface of the bracket groove 114.

[0084] In one example, see Figure 7 The bracket includes several reinforcing ribs 115, including arc-shaped reinforcing ribs 1151, with two arc-shaped reinforcing ribs 1151 arranged opposite to each other. A column 116 is also provided on the bottom surface of the support groove 114, with two columns 116 arranged opposite to each other along the thickness direction of the battery rod 10. Through holes within the columns 116 are used to form a portion of the electrode hole 117 along the axial direction. The two ends of the two arc-shaped reinforcing ribs 1151 are respectively connected to the two columns 116 to form a recessed groove 111.

[0085] In one example, see Figure 9 The two ends of the sealing side 122 along the length direction are arc-shaped, and the middle area of ​​the sealing side 122 on both sides is recessed inward along the width direction of the air passage seal 12.

[0086] In one example, see Figure 7The magnetic component mounting groove 119 is formed by reinforcing ribs 115.

[0087] In one embodiment, please refer to Figure 7 A recessed groove 113 is provided on the bottom surface of the recessed groove 111, and the first end 1121 of the air passage opens to the bottom surface of the recessed groove 113. The air hole 124 on the air passage seal 12 is connected to the recessed groove 113.

[0088] In this embodiment of the application, a recessed groove 113 is provided on the bottom surface of the recessed groove 111 to facilitate the connection between the air hole 124 on the air passage seal 12 and the first end 1121 of the air passage.

[0089] It is worth noting that the above embodiment describes a recessed groove 113 provided on the bottom surface of the recessed groove 111. In other embodiments, a groove may also be provided on the side of the bottom 121 of the seal near the bottom of the recessed groove 111, with one end of the air hole 124 extending into the groove, and the groove communicating with the first end 1121 of the air passage.

[0090] In one embodiment, please refer to Figure 9 A boss 127 is formed on the bottom surface of the gas chamber 123 of the air passage seal 12, and an air hole 124 penetrates the boss 127.

[0091] In this embodiment, by providing a boss 127, the strength of the airway seal 12 is increased, thus preventing the airway seal 12 from being easily damaged at the position of the air hole 124.

[0092] Please see Figure 11 , Figure 11 This is a cross-sectional schematic diagram of the airway seal 12 provided in an embodiment of this application.

[0093] In one embodiment, the thickness of the flared region of the seal side 122 decreases along the direction away from the bottom 121 of the seal.

[0094] For ease of description, the flared area on the side 122 of the seal is referred to as the flared area 1221. Please refer to [link to relevant documentation]. Figure 11 The diagram illustrates the flared area 1221, and the thickness of the flared area 1221 decreases along the direction away from the bottom 121 of the seal.

[0095] In this embodiment, the thickness of the flared area 1221 is less than the thickness of other areas on the airway seal 12 except for the flared area 1221, so that the other areas on the airway seal 12 except for the flared area 1221 have sufficient strength, while also ensuring that the flared area 1221 is easy to undergo elastic deformation, so as to achieve a sealing fit with the bottom of the atomizer 20.

[0096] Please see Figures 12-13 , Figure 12 This is a bottom view of the airway seal 12 provided in the embodiments of this application. Figure 13 An exploded view of the battery holder 11 and the anti-detachment component 15 provided in the embodiments of this application.

[0097] In one embodiment, please refer to Figure 12 Two air holes 124 are provided on the bottom 121 of the seal, and the two air holes 124 are spaced apart along the length direction of the bottom 121 of the seal; the air passage seal 12 has a symmetrical structure, and the axis of symmetry of the air passage seal 12 is parallel to the width direction of the bottom 121 of the seal. Please refer to Figure 12 , Figure 12 The axis of symmetry of the airway seal 12 is indicated by the dashed line L.

[0098] Two air holes 124 are provided on the bottom 121 of the seal. For ease of description, the two air holes 124 are referred to as the first air hole and the second air hole, respectively. When the air passage seal 12 is installed in the recessed groove 111 of the battery bracket 11, the first air hole can be set close to the first end 1121 of the detection air passage 112, or the second air hole can be set close to the first end 1121 of the detection air passage 112.

[0099] When a vent 124 is provided on the bottom 121 of the seal, when the air passage seal 12 is installed in the recessed groove 111 of the battery bracket 11, the positional relationship between the air passage seal 12 and the recessed groove 111 along the length direction needs to be considered so that the vent 124 is close to the first end 1121 of the detection air passage 112. However, in this application, by providing two vents 124 on the bottom 121 of the seal and setting the air passage seal 12 to a symmetrical structure, when the air passage seal 12 is installed in the recessed groove 111 on the battery bracket 11, the positional relationship between the air passage seal 12 and the recessed groove 111 along the length direction of the air passage seal 12 does not need to be considered, which facilitates the rapid installation of the air passage seal 12.

[0100] In one embodiment, please refer to Figure 12 The airway seal 12 also includes a limiting portion 125, which is disposed on the outer peripheral side of the seal side portion 122. Please refer to [link to relevant documentation]. Figure 13 When the airway seal 12 is located in the recessed groove 111, the limiting part 125 is located outside the recessed groove 111.

[0101] In the embodiments of this application, please refer to Figure 13The battery rod 10 also includes an anti-detachment component 15. The anti-detachment component 15 is fixed at one end of the battery bracket 11 with a recessed groove 111. The anti-detachment component 15 is provided with a clearance hole 151 to avoid the side portion 122 of the sealing component. When the airway sealing component 12 is located in the recessed groove 111, the limiting portion 125 of the airway sealing component 12 is limited between the anti-detachment component 15 and the battery bracket 11.

[0102] In this embodiment, by setting the limiting part 125 of the air passage seal 12 to be limited between the anti-detachment member 15 and the battery bracket 11, the air passage seal 12 can be further limited on the battery bracket 11.

[0103] In one example, the number of anti-detachment parts 15 is one or more, and when the number of anti-detachment parts 15 is two or more, different anti-detachment parts 15 may be located at different parts of the blocking and limiting part 125.

[0104] In one example, the anti-detachment member 15 is only used to block the limiting portion 125 of the airway seal 12, and does not block the magnetic member 17 mounted on the battery bracket 11; or, in other examples, the anti-detachment member 15 blocks both the limiting portion 125 of the airway seal 12 and the magnetic member 17 mounted on the battery bracket 11, so as to prevent the magnetic member 17 from detaching from the battery bracket 11.

[0105] In one example, see Figure 13 The clearance hole 151 on the anti-detachment component 15 includes a first clearance hole 1511 and a second clearance hole 1512. The two second clearance holes 1512 are arranged opposite to each other on both sides of the first clearance hole 1511. Both second clearance holes 1512 are connected to the first clearance hole 1511. The shape of the first clearance hole 1511 is the same as that of the recessed groove 111 on the battery holder 11. The first clearance hole 1511 is used to avoid the flared area 1221 on the anti-detachment component 15. The two second clearance holes 1512 are respectively located above the two corresponding electrode holes 117.

[0106] In one example, while implementing the avoidance hole 151 to avoid the electrode hole 117 and the flared area 1221, the shape of the avoidance hole 151 can also be set to be the same as the outer contour shape of the anti-detachment member 15; or, the avoidance hole 151 can be set to other shapes.

[0107] In this embodiment, the anti-detachment component 15 is fixed to the battery bracket 11, meaning that the anti-detachment component 15 can be detachably connected to the battery bracket 11 or non-detachably connected to the battery bracket 11.

[0108] For example, in one example, the anti-detachment component 15 is snapped onto the battery holder 11 by a snap-fit ​​structure, or the anti-detachment component 15 is connected to the battery holder 11 by a connector such as a screw, bolt or rivet.

[0109] In one embodiment, the anti-detachment component 15 includes a rigid layer and an adhesive layer, with the adhesive layer disposed on one side of the rigid layer and bonded to the battery holder 11.

[0110] In one example, the rigid layer is made of plastic, such as polycarbonate (PC).

[0111] In one example, the thickness of the hard layer ranges from 0.5 to 3.0 mm. For instance, the thickness of the hard layer could range from 0.5 to 1.0 mm, or 1.0 to 1.5 mm, or 1.5 to 2.0 mm, or 2.0 to 2.5 mm, or 2.5 to 3.0 mm, etc.

[0112] In one example, an adhesive layer is provided on the entire side of the rigid layer near the battery holder 11; or, in other examples, an adhesive layer is provided on a portion of the rigid layer near the battery holder 11.

[0113] In one example, the thickness of the adhesive layer ranges from 0.1 to 1.0 mm. For instance, the thickness of the adhesive layer may range from 0.1 to 0.2 mm, or 0.2 to 0.3 mm, or 0.3 to 0.4 mm, or 0.4 to 0.5 mm, or 0.5 to 0.6 mm, or 0.6 to 0.7 mm, or 0.7 to 0.8 mm, or 0.8 to 0.9 mm, or 0.9 to 1.0 mm, etc.

[0114] In this embodiment, by providing the anti-detachment component 15, which includes a hard layer and an adhesive layer, the anti-detachment component 15 can be attached to the battery bracket 11, and the connection method between the anti-detachment component 15 and the battery bracket 11 is simple.

[0115] In one embodiment, please refer to Figure 12 The limiting part 125 includes a limiting circumferential part 1251 and a limiting extension part 1252. The limiting circumferential part 1251 is connected to the outer circumferential side of the sealing side part 122, and one end of the limiting extension part 1252 is connected to the limiting circumferential part 1251.

[0116] In one example, the limiting circumferential portion 1251 is annular; in other examples, please refer to Figure 12 Along the width direction of the air passage seal 12, the middle area of ​​the side portion 122 of the seal is recessed inward on both sides. The recessed area can be called the recessed area. The recessed area can be provided without the limiting circumferential portion 1251. The two arc ends of the side portion 122 of the seal are provided with the limiting circumferential portion 1251 along the length direction.

[0117] In one example, the two arc-shaped ends of the sealing side 122 along the length direction are provided with limiting circumferential portions 1251, the length of which along the radial direction of the airway seal 12 is greater than the length along the radial direction of the limiting extension 1252 located in the recessed area, wherein the radial direction is the direction from the center of the airway seal 12 to the circumferential edge.

[0118] In one example, in the limiting circumferential portion 1251 and the limiting extension portion 1252, the anti-detachment member 15 at least covers the limiting extension portion 1252.

[0119] In one example, see Figure 8 The limiting extension 1252 is rectangular.

[0120] In one example, there are multiple limiting extensions 1252, which are symmetrically arranged on the limiting circumferential portion 1251. See also... Figure 11 The diagram shows that there are four limiting extensions 1252, and each pair of limiting extensions 1252 are symmetrically arranged at both ends of the airway seal 12 along the length direction.

[0121] In one embodiment, please refer to Figure 13 An annular boss 118 is formed on the end face of the recessed groove 111 of the battery bracket 11. The annular boss 118 is provided along the circumferential edge of the battery bracket 11. The anti-detachment member 15 is provided at one end of the battery bracket 11 and located in the annular boss 118.

[0122] In one example, the annular boss 118 is generally annular; or, in other examples, the annular boss 118 includes a plurality of protrusions, which are evenly spaced along the circumferential direction of the battery holder 11.

[0123] In one example, the number of anti-detachment parts 15 is one, and the shape enclosed by the annular boss 118 is the same as the outer contour shape of the anti-detachment part 15; or, in other examples, the number of anti-detachment parts 15 is multiple, and the outer contour shape of the graphic formed by the multiple anti-detachment parts 15 is the same as the shape enclosed by the annular boss 118.

[0124] In one example, see Figure 13 The outer contour of the anti-slip component 15 is elliptical.

[0125] In one example, the height of the annular boss 118 protruding from the end face of the battery holder 11 is not less than the thickness of the anti-detachment member 15; or, in other examples, the height of the annular boss 118 protruding from the end face of the battery holder 11 is less than the thickness of the anti-detachment member 15.

[0126] In this embodiment, by setting the anti-detachment component 15 inside the annular boss 118, the installation position of the anti-detachment component 15 can be limited, making it convenient to fix the anti-detachment component 15 on the battery bracket 11.

[0127] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
