Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a nozzle sealing structure and an aerosol generation device. Background Technology

[0002] An aerosol generator is an electronic device that produces aerosols through atomization technology. It mainly includes a housing, a nozzle, a support, atomizing components, and a power supply. The nozzle is typically located at the top of the housing, and its seal with the support is usually achieved using silicone sealant inside the housing.

[0003] In related technologies, the sealing silicone is usually placed on a support to form a component, and then this component is assembled with the nozzle. In this method, during the transportation of the component or during the subsequent assembly of the component with the nozzle, the sealing silicone may fall off the support, resulting in the failure of the sealing function and affecting the normal use of the aerosol generating device. Utility Model Content

[0004] This application provides a nozzle sealing structure and an aerosol generating device, which can prevent the sealing silicone from falling off the support and causing the sealing function to fail, thus affecting the normal use of the aerosol generating device.

[0005] In a first aspect, embodiments of this application provide a suction nozzle sealing structure, including a suction nozzle and a bracket. The suction nozzle is provided with a connecting portion; the bracket is provided with a connecting hole, at least a portion of the connecting portion is accommodated in the connecting hole, the bracket includes a rigid portion and a first soft portion connected to each other, the hardness of the first soft portion is less than the hardness of the rigid portion, the first soft portion defines at least a portion of the inner wall of the connecting hole, and the first soft portion abuts against the connecting portion.

[0006] The nozzle sealing structure provided in this application has the following advantages: Since the nozzle is provided with a connecting part and the bracket is provided with a connecting hole, at least part of the connecting part is accommodated in the connecting hole, and the bracket includes a connected hard part and a first soft part, the hardness of the first soft part is less than the hard part, and the first soft part defines at least part of the inner wall of the connecting hole. Therefore, the connection between the connecting part of the nozzle and the inner wall of the connecting hole of the bracket can be sealed by the first soft part abutting against the connecting part. The hard part can also ensure that the bracket has a certain strength. Furthermore, by connecting the hard part and the first soft part, the first soft part can be prevented from falling off the hard part, which would cause the sealing function to fail, thus ensuring the normal use of the aerosol generating device.

[0007] In some embodiments, the first soft portion includes a first portion and a second portion connected together, the second portion protruding relative to the first portion toward an axis close to the connecting hole, and the second portion extending circumferentially along the connecting hole, the second portion abutting against the connecting portion.

[0008] By adopting the above solution, the second part can be tightly abutted against the connecting part, thereby effectively ensuring the sealing between the connecting part and the inner wall of the connecting hole.

[0009] In some embodiments, multiple second parts are provided, and the multiple second parts are spaced apart along the axial direction of the connecting hole.

[0010] By adopting the above solution, the sealing performance between the connection part and the inner wall of the connection hole can be improved.

[0011] In some embodiments, the support includes a second soft portion, the hardness of which is less than that of the hard portion. Both the hard portion and the first soft portion are connected to the second soft portion. The second soft portion defines a first surface of the support, and the first surface is connected to the inner wall of the connecting hole.

[0012] By adopting the above solution, both the first soft part and the second soft part can be connected to the hard part. Since the first soft part and the second soft part are also connected, both the first soft part and the second soft part can be tightly connected to the hard part and are not easy to detach from the hard part.

[0013] In some embodiments, the support includes a third soft portion, the hardness of which is less than that of the hard portion. Both the hard portion and the second soft portion are connected to the third soft portion, and the third soft portion defines a second surface of the support, the second surface being disposed opposite to the inner wall of the connecting hole.

[0014] By adopting the above solution, the first soft part, the second soft part, and the third soft part can all be connected to the hard part. Since the first soft part, the second soft part, and the third soft part are also connected, the first soft part, the second soft part, and the third soft part can be tightly connected to the hard part and are not easy to detach from the hard part.

[0015] In some embodiments, the rigid part is made of plastic, metal or ceramic; and / or, the first soft part is made of silicone, rubber or TPE.

[0016] By adopting the above solution, it becomes easier to manufacture the hard part and the first soft part.

[0017] Secondly, embodiments of this application provide an aerosol generating device, which includes an outer shell and a nozzle sealing structure as described in the first aspect, wherein the support is disposed inside the outer shell.

[0018] The aerosol generating device provided in this application has the following advantages: Since the nozzle is provided with a connecting part and the bracket is provided with a connecting hole, at least a portion of the connecting part is accommodated in the connecting hole, and the bracket includes a rigid part and a first soft part connected to each other, the hardness of the first soft part is less than the hardness of the rigid part, and the first soft part defines at least a portion of the inner wall of the connecting hole. Therefore, the connection between the connecting part of the nozzle and the inner wall of the connecting hole of the bracket can be sealed by the first soft part abutting against the connecting part. The rigid part can also ensure that the bracket has a certain strength. Furthermore, by connecting the rigid part and the first soft part, the first soft part can be prevented from falling off the rigid part, which would cause the sealing function to fail, thus ensuring the normal use of the aerosol generating device.

[0019] In some embodiments, the suction nozzle includes a main body and a flange disposed on the outer surface of the main body, the connecting part is disposed inside the main body, the outer shell is provided with a mounting groove, the bottom wall of the mounting groove is provided with a through hole, a portion of the main body is located in the through hole, and the flange abuts against the bottom surface of the mounting groove.

[0020] By adopting the above solution, the main body can be prevented from moving towards the bracket by the flange abutting against the bottom surface of the mounting groove, and the position of the main body can be restricted by the inner wall of the through hole.

[0021] In some embodiments, the nozzle further includes a limiting portion connected to the main body, the inner wall surface of the outer shell abutting against the limiting portion, and the bottom surface of the mounting groove being disposed opposite to the inner wall surface.

[0022] By adopting the above solution, the inner wall surface of the outer shell abuts against the limiting part to prevent the main body from moving away from the bracket, thereby cooperating with the flange to limit the position of the main body in the axial direction of the through hole.

[0023] In some embodiments, the main body is provided with a guide portion, the outer shell is provided with a mating portion, the guide portion and the mating portion are slidably engaged, and the sliding direction of the guide portion relative to the mating portion is parallel to the depth direction of the mounting groove.

[0024] By adopting the above solution, the main body can be easily placed into the mounting slot, so that part of the main body is located in the through hole. Attached Figure Description

Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0044] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0045] An aerosol generator is an electronic device that produces aerosols through atomization technology. It mainly includes a housing, a nozzle, a support, atomizing components, and a power supply. The nozzle is typically located at the top of the housing, and its seal with the support is usually achieved through an interference fit with silicone sealant.

[0046] In related technologies, the sealing silicone is usually placed on a support to form a component, and then this component is assembled with the nozzle. In this way, during the transportation of the component or during the subsequent assembly of the component with the nozzle, the sealing silicone may fall off the support, which may cause the sealing function to fail and affect the normal use of the aerosol generating device.

[0047] In view of this, this application provides a nozzle sealing structure and an aerosol generating device. Since the nozzle is provided with a connecting part and the bracket is provided with a connecting hole, at least a portion of the connecting part is accommodated in the connecting hole, and the bracket includes a rigid part and a first soft part connected together, the hardness of the first soft part is less than the hardness of the rigid part, and the first soft part defines at least a portion of the inner wall of the connecting hole. Therefore, the connection between the connecting part of the nozzle and the inner wall of the connecting hole of the bracket can be sealed by the first soft part abutting against the connecting part. The rigid part can also ensure that the bracket has a certain strength. Furthermore, by connecting the rigid part and the first soft part, the first soft part can be prevented from falling off the rigid part, which would cause the sealing function to fail, thus ensuring the normal use of the aerosol generating device.

[0048] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the aerosol generating device 100 in one embodiment of this application. Figure 2 yes Figure 1 The diagram shown is an exploded view of the aerosol generating device 100. Figure 3 yes Figure 2 A magnified view of a portion of point A in the middle. Figure 4 yes Figure 1 The diagram shows a front view of the aerosol generating apparatus 100. Figure 5 yes Figure 4 The aerosol generating apparatus 100 shown is a cross-sectional view along the MM direction. Figure 6 yes Figure 5 A magnified view of a section at point B.

[0049] In a first aspect, embodiments of this application provide a nozzle sealing structure that can be used in an aerosol generating device 100. The nozzle sealing structure includes a nozzle 10 and a support 20, and the nozzle 10 is provided with a connecting portion 11.

[0050] The bracket 20 is provided with a connection hole 201, and at least a portion of the connection portion 11 is accommodated in the connection hole 201. The bracket 20 includes a rigid portion 21 and a first soft portion 22 connected to each other. The hardness of the first soft portion 22 is less than that of the rigid portion 21. The first soft portion 22 defines at least a portion of the inner wall of the connection hole 201, and the first soft portion 22 abuts against the connection portion 11.

[0051] The rigid part 21 can be made of plastic, metal, or ceramic. The first soft part 22 can be made of silicone, rubber, or TPE (Thermoplastic Elastomer). The rigid part 21 and the first soft part 22 can be connected by bonding or fused together by an overmolding process to form a single part. The first soft part 22 will not detach from the rigid part 21 during transportation, which facilitates automation.

[0052] Since the hardness of the first soft part 22 is less than that of the hard part 21, the first soft part 22 defines at least a portion of the inner wall of the connecting hole 201, and the first soft part 22 abuts against the connecting part 11. Therefore, the first soft part 22 can ensure the sealing between the connection between the connecting part 11 and the inner wall of the connecting hole 201, and the hard part 21 can ensure that the bracket 20 has sufficient strength to meet the usage requirements.

[0053] As can be seen from the above, the nozzle sealing structure provided in this application embodiment has a connecting part 11 on the nozzle 10 and a connecting hole 201 on the bracket 20. At least part of the connecting part 11 is accommodated in the connecting hole 201. The bracket 20 includes a hard part 21 and a first soft part 22 connected to each other. The hardness of the first soft part 22 is less than that of the hard part 21. The first soft part 22 defines at least part of the inner wall of the connecting hole 201. Therefore, the first soft part 22 can abut against the connecting part 11 to seal the connection between the connecting part 11 of the nozzle 10 and the inner wall of the connecting hole 201 of the bracket 20. The hard part 21 can also ensure that the bracket 20 has a certain strength. Furthermore, by connecting the hard part 21 and the first soft part 22, the first soft part 22 can be prevented from falling off the hard part 21, which would cause the sealing function to fail and ensure the normal use of the aerosol generating device 100.

[0054] It should be noted that a vent hole 101 may also be provided inside the connecting part 11 of the nozzle 10. The axis of the vent hole 101 may be parallel to the axis of the connecting hole 201. The aerosol generated inside the aerosol generating device 100 is discharged through the vent hole 101 and will not leak from the connection between the connecting part 11 and the inner wall of the connecting hole 201.

[0055] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the first soft portion 22 includes a first portion 221 and a second portion 222 connected to each other. The second portion 222 protrudes relative to the first portion 221 toward the axis of the connecting hole 201 and extends circumferentially along the connecting hole 201. The second portion 222 abuts against the connecting portion 11.

[0056] By adopting the above solution, the second part 222 can be tightly abutted against the connecting part 11, thereby effectively ensuring the sealing between the connection between the connecting part 11 and the inner wall of the connecting hole 201.

[0057] It should be noted that the first part 221 and the second part 222 can be set up as a whole, such as by injection molding.

[0058] Optionally, multiple second parts 222 are provided, and the multiple second parts 222 are spaced apart along the axial direction of the connecting hole 201.

[0059] This design allows for a better seal between the connection between the connecting part 11 and the inner wall of the connecting hole 201.

[0060] Please continue to refer to this. Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the support 20 includes a second soft portion 23, the hardness of which is less than that of the hard portion 21. Both the hard portion 21 and the first soft portion 22 are connected to the second soft portion 23. The second soft portion 23 defines a first surface of the support 20, which is connected to the inner wall of the connection hole 201.

[0061] By adopting the above solution, both the first soft part 22 and the second soft part 23 can be connected to the hard part 21. Since the first soft part 22 and the second soft part 23 are also connected, the first soft part 22 and the second soft part 23 can be tightly connected to the hard part 21 and are not easy to detach from the hard part 21.

[0062] Optionally, the bracket 20 includes a third soft portion 24, the hardness of which is less than that of the hard portion 21. The hard portion 21 and the second soft portion 23 are both connected to the third soft portion 24, and the third soft portion 24 defines a second surface of the bracket 20. The second surface is disposed opposite to the inner wall of the connecting hole 201.

[0063] By adopting the above solution, the first soft part 22, the second soft part 23, and the third soft part 24 can all be connected to the hard part 21. Since the first soft part 22, the second soft part 23, and the third soft part 24 are also connected, the first soft part 22, the second soft part 23, and the third soft part 24 can be tightly connected to the hard part 21 and are not easy to detach from the hard part 21.

[0064] It should be noted that the first soft part 22, the second soft part 23, and the third soft part 24 can be integrally formed, such as by integral injection molding. The materials of the first soft part 22, the second soft part 23, and the third soft part 24 can be the same.

[0065] Optionally, the rigid part 21 may be made of plastic, metal or ceramic; and / or the first soft part 22 may be made of silicone, rubber or TPE.

[0066] This design makes it easier to manufacture the hard part 21 and the first soft part 22.

[0067] It is understandable that the material of the second soft part 23 and the third soft part 24 can also be silicone, rubber, or TPE. The second soft part 23 and the third soft part 24 can be connected to the hard part 21 by bonding or by fusion through an overmolding process to directly form a single part.

[0068] Please refer to Figures 1 to 6 Secondly, embodiments of this application provide an aerosol generating device 100, which includes a housing 30 and a nozzle sealing structure as described in the first aspect, with a bracket 20 disposed inside the housing 30.

[0069] The aerosol generating device 100 provided in this application embodiment has a connecting portion 11 on the nozzle 10 and a connecting hole 201 on the bracket 20. At least a portion of the connecting portion 11 is accommodated in the connecting hole 201. The bracket 20 includes a rigid portion 21 and a first soft portion 22 connected together. The hardness of the first soft portion 22 is less than that of the rigid portion 21. The first soft portion 22 defines at least a portion of the inner wall of the connecting hole 201. Therefore, the connection between the connecting portion 11 of the nozzle 10 and the inner wall of the connecting hole 201 of the bracket 20 can be sealed by the first soft portion 22 abutting against the connecting portion 11. The rigid portion 21 can also ensure that the bracket 20 has a certain strength. Furthermore, by connecting the rigid portion 21 and the first soft portion 22, the first soft portion 22 can be prevented from falling off the rigid portion 21, which would cause the sealing function to fail, thus ensuring the normal use of the aerosol generating device 100.

[0070] It is understood that the aerosol generating device 100 provided in the embodiments of this application may also include atomizing components, power supply and circuit board, etc., which will not be described in detail here.

[0071] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the suction nozzle 10 includes a main body 12 and a flange 13 disposed on the outer surface of the main body 12. The connecting part 11 is disposed inside the main body 12. The outer shell 30 is provided with a mounting groove 31. The bottom wall of the mounting groove 31 is provided with a through hole 32. Part of the main body 12 is located in the through hole 32. The flange 13 abuts against the bottom surface of the mounting groove 31.

[0072] By adopting the above solution, the main body 12 can be prevented from moving closer to the bracket 20 by the flange 13 abutting against the bottom surface of the mounting groove 31, and the position of the main body 12 can be restricted by the inner wall of the through hole 32.

[0073] It should be noted that the axis of the through hole 32 can be parallel to the axis of the connecting hole 201.

[0074] Optionally, the nozzle 10 also includes a limiting part 14, which is connected to the main body 12. The inner wall surface 33 of the outer shell 30 abuts against the limiting part 14, and the bottom surface of the mounting groove 31 is disposed opposite to the inner wall surface 33.

[0075] With this configuration, the inner wall surface 33 of the outer casing 30 abuts against the limiting part 14 to prevent the main body 12 from moving away from the bracket 20, thereby cooperating with the flange 13 to limit the position of the main body 12 in the axial direction of the through hole 32.

[0076] Multiple limiting parts 14 may be provided and the multiple limiting parts 14 are spaced apart to better prevent the main body 12 from moving away from the bracket 20.

[0077] Optionally, the main body 12 is provided with a guide portion 15, and the outer shell 30 is provided with a mating portion (not shown in the figure). The guide portion 15 is slidably engaged with the mating portion, and the sliding direction of the guide portion 15 relative to the mating portion is parallel to the depth direction of the mounting groove 31.

[0078] This arrangement allows the main body 12 to be easily placed into the mounting slot 31, so that part of the main body 12 is located in the through hole 32.

[0079] In this configuration, one of the guide portion 15 and the mating portion can be configured as a groove, and the other of the guide portion 15 and the mating portion can be configured as a slider. Multiple guide portions 15 and mating portions can be provided, and each guide portion 15 and mating portion is configured in a one-to-one correspondence.

[0080] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
