Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and particularly to a housing assembly, an atomizer, and an aerosol generating device. Background Technology

[0002] Housing assemblies are typically the outermost structure of equipment, primarily used to house other structures and provide protection. To facilitate equipment assembly or enhance aesthetics, housing assemblies usually consist of at least two housings that are assembled together to form a single unit. These housings can have different colors or be made of different materials.

[0003] For small devices such as atomizers and aerosol generators, the housing components are typically assembled manually or using small automated equipment. The structure of the housing components has a significant impact on the ease of assembly and also affects production efficiency.

[0004] Currently, some housing components are either easy to assemble but have unstable connections and are easy to separate, or have stable connections and are not easy to separate but are difficult to assemble, making it difficult to balance the convenience of assembly and the stability of the connection. Utility Model Content

[0005] This application provides a housing assembly, an atomizer, and an aerosol generating device, which are easy to assemble, structurally stable, and not easily separated. The technical solution is as follows:

[0007] The second housing includes a first part and a second part connected together, the first part having a second plug-in structure on the side away from the second part, and the second part having a second snap-fit ​​structure on the side away from the first part;

[0008] The first part is located on the first side of the first housing, and the second plug-in structure is plugged into the first plug-in structure;

[0009] The second part is located on the second side of the first housing, and the second snap-fit ​​structure snaps into the first snap-fit ​​structure.

[0010] In some examples, one of the first plug-in structure and the second plug-in structure includes a first plug-in board, and the other of the first plug-in structure and the second plug-in structure includes a first plug-in interface;

[0011] The first plug plate passes through the first plug interface at least partially. The first plug plate cooperates with the first plug interface to allow the second housing to rotate relative to the first housing, so that the second snap-fit ​​structure moves closer to or further away from the first snap-fit ​​structure.

[0012] In some examples, the first side of the first housing has a stop structure, the stop structure including a stop surface and a mating surface, the stop surface and the mating surface intersecting, the stop surface being used to abut against the side of the first portion away from the second portion, and the mating surface being used to fit against the first portion.

[0013] In some examples, the first plug-in structure includes a first plug-in interface, a portion of which is located on the stop surface and another portion of which is located on the mating surface.

[0014] In some examples, the first side of the first housing also has a third plug-in structure;

[0015] The first part also has a fourth plug-in structure on the side near the first housing, and the fourth plug-in structure is plugged into the third plug-in structure.

[0016] In some examples, the second side of the first housing also has a fifth plug-in structure;

[0017] The second part also has a sixth plug-in structure on the side near the first housing, which plugs into the fifth plug-in structure.

[0018] In some examples, the first housing has an opening located on a side of the first housing that is adjacent to both the first side and the second side;

[0019] The second housing further includes a splicing portion connected to the edge of the first portion, the splicing portion being located in the opening to close at least a portion of the opening.

[0020] In some examples, the opening has a seventh plug-in structure on the side away from the first side;

[0021] The splicing part has an eighth insertion structure at its edge away from the first part, and the eighth insertion structure is inserted into the seventh insertion structure.

[0022] Secondly, embodiments of this application also provide an atomizer, the atomizer including an atomizing component, a liquid storage component, and a housing component as described in the first aspect, wherein the atomizing component and the liquid storage component are both located in the first housing.

[0023] Thirdly, embodiments of this application also provide an aerosol generating device, which includes an atomizing component, a liquid storage component, a power supply component, and any of the housing components described in the first aspect, wherein the atomizing component, the liquid storage component, and the power supply component are all located in the first housing; or,

[0024] The aerosol generating device includes a power supply component and an atomizer as described in the second aspect, wherein the power supply component is connected to the atomizer and is used to supply power to the atomizer.

[0025] The beneficial effects of the technical solutions provided in this application include at least the following:

[0026] By setting up a first housing and a second housing, the first housing has a first plug-in structure and a first snap-fit ​​structure, and the second housing has a second plug-in structure and a second snap-fit ​​structure. The first housing and the second housing are assembled together through the cooperation of the first plug-in structure and the second plug-in structure, and the cooperation of the first snap-fit ​​structure and the second snap-fit ​​structure. Since the first plug-in structure and the first snap-fit ​​structure are located on different sides of the first housing, the second plug-in structure is located on the side of the first part of the second housing away from the second part, and the second snap-fit ​​structure is located on the side of the second part of the second housing away from the first part, when assembling the first housing and the second housing, the first plug-in structure and the second plug-in structure can be plugged together first to initially locate the relative positions of the first housing and the second housing, and then the first snap-fit ​​structure and the second snap-fit ​​structure can be snapped together to further lock the relative positions of the first housing and the second housing. The first plug-in structure and the second plug-in structure cooperate by plugging in, which has little impact on the operation of the first snap-fit ​​structure and the second snap-fit ​​structure engaging with each other, and the assembly is convenient. Assembling the first housing and the second housing using both plugging and snap-fit ​​methods on different sides of the first housing results in a stable structure that is not easily separated.

[0046] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 is used to supply power to the atomizer 200.

[0047] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Because the power supply assembly 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0048] For example, atomizer 200 may include housing assembly 300, and power supply assembly 100 may be detachably connected to housing assembly 300.

[0049] Figure 2 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 2 As shown, the aerosol generating device includes a power supply component 100, an atomizer 200, and a housing assembly 300, with the power supply component 100 and the atomizer 200 located within the housing assembly 300. In this aerosol generating device, the power supply component 100 and the atomizer 200 share a common housing structure.

[0050] Figure 3 This is a schematic diagram of a housing assembly provided in an embodiment of this application. The housing assembly can be the housing assembly 300 of the atomizer 200, or it can be the housing assembly 300 in an aerosol generating device used to house the power supply assembly 100 and the atomizer 200. Figure 3 As shown, the housing assembly includes a first housing 310 and a second housing 320. The first housing 310 has a first plug-in structure 311 on a first side and a first snap-fit ​​structure 312 on a second side.

[0051] As an example, the second side of the first housing 310 may be adjacent to the first side of the first housing 310.

[0052] In other possible implementations, the second side of the first housing 310 may not be adjacent to the first side of the first housing 310, for example, they may be spaced apart from each other or opposite each other.

[0053] The second housing 320 includes a first part 321 and a second part 322 connected together, and the first part 321 has a second plug-in structure 323 on the side away from the second part 322. Figure 4 This is a schematic diagram of the structure of a second shell provided in an embodiment of this application, as shown below. Figure 4 As shown, the second part 322 has a second snap-fit ​​structure 324 on the side away from the first part 321.

[0054] As an example, the second side of the first housing 310 is adjacent to the first side of the first housing 310, and the second portion 322 of the second housing 320 is connected to the first portion 321 of the second housing 320, forming an L-shape or an inverted L-shape. Both the first portion 321 and the second portion 322 can be plate-shaped.

[0055] The first part 321 is located on the first side of the first housing 310, and the second plug-in structure 323 is plugged into the first plug-in structure 311; the second part 322 is located on the second side of the first housing 310, and the second snap-fit ​​structure 324 is snap-fitted into the first snap-fit ​​structure 312.

[0056] By providing a first housing 310 and a second housing 320, the first housing 310 has a first insertion structure 311 and a first snap-fit ​​structure 312, and the second housing 320 has a second insertion structure 323 and a second snap-fit ​​structure 324. The first housing 310 and the second housing 320 are assembled together by the cooperation of the first insertion structure 311 and the second insertion structure 323, and the cooperation of the first snap-fit ​​structure 312 and the second snap-fit ​​structure 324. Since the first insertion structure 311 and the first snap-fit ​​structure 312 are located on different sides of the first housing 310, the second insertion structure 323 is located on the side of the first part 321 of the second housing 320 away from the second part 322, and the second snap-fit ​​structure 324 is located on the side of the second part 322 of the second housing 320 away from the first part 321, when assembling the first housing 310 and the second housing 320, the first insertion structure 311 and the second insertion structure 323 can be inserted together first to initially position the relative positions of the first housing 310 and the second housing 320. Then, the first snap-fit ​​structure 312 and the second snap-fit ​​structure 324 can be snapped together to further lock the relative positions of the first housing 310 and the second housing 320. The first insertion structure 311 and the second insertion structure 323 cooperate by insertion, which has little impact on the process of the first snap-fit ​​structure 312 and the second snap-fit ​​structure 324 engaging with each other, making assembly convenient. The first housing 310 and the second housing 320 are assembled on different sides of the first housing 310 using both plug-in and snap-fit ​​methods, resulting in a stable structure that is not easily separated.

[0057] The first housing 310 and the second housing 320 may differ in at least one of the following: color, light transmittance, and material. For example, the first housing 310 or a portion thereof may be transparent.

[0058] In some examples, one of the first snap-fit ​​structure 312 and the second snap-fit ​​structure 324 includes a hook 3120, and the other of the first snap-fit ​​structure 312 and the second snap-fit ​​structure 324 includes a slot 3240. The hook 3120 snaps into the slot 3240.

[0059] In some examples, one of the first plug-in structure 311 and the second plug-in structure 323 includes a first plug-in plate 3230, and the other of the first plug-in structure 311 and the second plug-in structure 323 includes a first plug-in interface 3110. The first plug-in plate 3230 is plugged into the first plug-in interface 3110.

[0060] Figure 5 This is an assembly diagram of a first housing and a second housing provided in an embodiment of this application, as shown below. Figure 5As shown, the first plug plate 3230 passes through the first plug interface 3110 at least partially. The first plug plate 3230 cooperates with the first plug interface 3110, so that the second housing 320 can rotate relative to the first housing 310, so that the second snap-fit ​​structure 324 moves closer to or away from the first snap-fit ​​structure 312.

[0061] In this embodiment, the first insertion interface 3110 and the first insertion plate 3230 are not interference-fitted or zero-clearance, but rather have a relatively large clearance. For example, there is a large clearance on one side of the first insertion plate 3230, which allows the second housing 320 to rotate relative to the first housing 310 after the first insertion plate 3230 passes through the first insertion interface 3110, thereby facilitating the assembly of the first housing 310 and the second housing 320.

[0062] As an example, the first plug-in structure 311 may include a first plug-in interface 3110, and the second plug-in structure 323 may include a first plug-in plate 3230. When assembling the first housing 310 and the second housing 320, the first plug-in plate 3230 of the second plug-in structure 323 may first be plugged into the first plug-in interface 3110 of the first plug-in structure 311; then the second housing 320 may be rotated relative to the first housing 310 by a certain angle, so that the second part 322 of the second housing 320 moves to the second side of the first housing 310, and the second snap-fit ​​structure 324 gradually approaches the first snap-fit ​​structure 312; finally, the second snap-fit ​​structure 324 is snapped into the first snap-fit ​​structure 312, so that the second housing 320 and the first housing 310 are assembled together.

[0063] The first plug-in structure 311 may include two or more first plug-in interfaces 3110, and the second plug-in structure 323 may include two or more first plug-in plates 3230 to further improve the stability of the connection between the first housing 310 and the second housing 320.

[0064] In other possible implementations, the first plug-in structure 311 may include a first plug-in board 3230, and the second plug-in structure 323 may include a first plug-in interface 3110; or, the first plug-in structure 311 may include a first plug-in board 3230 and a first plug-in interface 3110, and the second plug-in structure 323 may include a first plug-in interface 3110 and a first plug-in board 3230.

[0065] Figure 6 This is a partial structural diagram of a first housing provided in an embodiment of this application, as shown below. Figure 6As shown, the first housing 310 has a stop structure 313 on its first side. The stop structure 313 includes a stop surface 3131 and a mating surface 3132, which intersect. The stop surface 3131 abuts against the side of the first portion 321 away from the second portion 322, and the mating surface 3132 is mated to the first portion 321. Exemplarily, the stop surface 3131 and the mating surface 3132 may be perpendicular to each other.

[0066] After the second housing 320 is assembled to the first housing 310, the first portion 321 of the first housing 310 abuts against the stop surface 3131 to reduce the gap between the edge of the first portion 321 and the stop surface 3131. Simultaneously, the stop surface 3131 also provides a limiting position for the second housing 320, preventing it from loosening and making the assembly of the second housing 320 and the first housing 310 more stable and tight. The first portion 321 also abuts against the mating surface 3132, which further stabilizes the first portion 321 under its support.

[0067] In some examples, the outer surface of the second housing 320 may be flush with the outer surface of the first housing 310. The outer surface of the second housing 320 may refer to the surface of the second housing 320 that is away from the first housing 310. For example, the thickness of the first housing 310 may be the same as the width of the mating surface 3132, thereby making the outer surface of the second housing 320 flush with the outer surface of the first housing 310, improving the smoothness of the outer surface of the housing assembly and avoiding obvious discontinuities on the outer surface of the housing assembly.

[0068] like Figure 6 As shown, a portion of the first insertion interface 3110 is located on the stop surface 3131, and another portion of the first insertion interface 3110 is located on the mating surface 3132.

[0069] In this example, the first insertion interface 3110 is located at the junction of the stop surface 3131 and the mating surface 3132. During the assembly of the first housing 310 and the second housing 320, the first insertion plate 3230 is inserted into the first insertion interface 3110, which provides space for the first insertion plate 3230 to move. As the second housing 320 is rotated relative to the first housing 310, causing the first portion 321 of the second housing 320 to gradually approach the first housing 310, the first insertion plate 3230 gradually rotates within the first insertion interface 3110 until it is located within the portion of the first insertion interface 3110 that is on the stop surface 3131.

[0070] Figure 7 This is a schematic diagram of the structure of a first housing provided in an embodiment of this application, as shown below. Figure 7 As shown, the first side of the first housing 310 also has a third insertion structure 314. (Refer to...) Figure 4The first part 321 also has a fourth plug-in structure 325 on the side near the first housing 310, and the fourth plug-in structure 325 is plugged into the third plug-in structure 314.

[0071] Both the third plug-in structure 314 and the fourth plug-in structure 325 may include at least one of the second plug-in plate 3250 and the second plug-in interface 3140.

[0072] As an example, the third plug-in structure 314 includes a second plug-in interface 3140, and the fourth plug-in structure 325 includes a second plug-in plate 3250. After the second housing 320 is assembled to the first housing 310, the second plug-in plate 3250 is plugged into the second plug-in interface 3140.

[0073] The cooperation of the third insertion structure 314 and the fourth insertion structure 325 can further restrict the relative positions of the first housing 310 and the second housing 320, for example, restricting the first housing 310 and the second housing 320 in... Figure 3 The relative displacement in the Z or Y direction shown improves the stability of the housing assembly and prevents the first housing 310 and the second housing 320 from separating.

[0074] In some examples, the third plug-in structure 314 may include two or more second plug-in interfaces 3140, and the fourth plug-in structure 325 may include two or more second plug-in plates 3250 to further improve the stability of the housing assembly. For example, in this example, the third plug-in structure 314 includes two second plug-in interfaces 3140, and the fourth plug-in structure 325 includes two second plug-in plates 3250 located on two opposite sides of the first portion 321.

[0075] like Figure 7 As shown, the second side of the first housing 310 also has a fifth insertion structure 315. (Refer to...) Figure 4 The second part 322 also has a sixth plug-in structure 326 on the side near the first housing 310, and the sixth plug-in structure 326 is plugged into the fifth plug-in structure 315.

[0076] Both the fifth plug-in structure 315 and the sixth plug-in structure 326 may include at least one of the third plug-in plate 3260 and the third plug-in interface 3150.

[0077] As an example, the fifth plug-in structure 315 includes a third plug-in interface 3150, and the sixth plug-in structure 326 includes a third plug-in plate 3260. After the second housing 320 is assembled to the first housing 310, the third plug-in plate 3260 is plugged into the third plug-in interface 3150.

[0078] The cooperation of the fifth insertion structure 315 and the sixth insertion structure 326 can further restrict the relative positions of the first housing 310 and the second housing 320, for example, restricting the first housing 310 and the second housing 320 in... Figure 3 The relative displacement in the X or Z direction shown improves the stability of the housing assembly and prevents the first housing 310 and the second housing 320 from separating.

[0079] In some examples, the fifth plug-in structure 315 may include two or more third plug-in interfaces 3150, and the sixth plug-in structure 326 may include two or more third plug-in plates 3260 to further improve the stability of the housing assembly. For example, in this example, the fifth plug-in structure 315 includes two third plug-in interfaces 3150, and the sixth plug-in structure 326 includes two third plug-in plates 3260 located on two opposite sides of the second portion 322.

[0080] like Figure 7 As shown, the first housing 310 has an opening 310a, which is located on a side of the first housing 310 adjacent to both the first side and the second side. (Refer to...) Figure 4 As shown, the second housing 320 also includes a splicing portion 3211, which is connected to the edge of the first portion 321 of the second housing 320. The splicing portion 3211 is located in the opening 310a to close at least a portion of the opening 310a.

[0081] The opening 310a is located on the side of the first housing 310 adjacent to both the first and second sides. The splicing portion 3211 is located at the opening 310a, meaning that the splicing portion 3211 is also located on the side of the first housing 310 adjacent to both the first and second sides. The splicing portion 3211 is connected to the first part 321 of the second housing 320. The splicing portion 3211 can restrict the second housing 320 and the first housing 310 from moving together. Figure 3 The relative displacement in the Y or Z direction shown makes the assembly of the first housing 310 and the second housing 320 more stable.

[0082] By providing an opening 310a, the splicing part 3211 can enter the opening 310a, which helps to reduce the height of the splicing part 3211 protruding relative to the outer surface of the first housing 310, and can even make the outer surface of the splicing part 3211 flush with the outer surface of the first housing 310, thereby reducing the discontinuity of the outer surface of the housing assembly.

[0083] As an example, the first housing 310 may have two openings 310a located on opposite sides of the first housing 310, and the second housing 320 includes two splicing portions 3211 located on opposite sides of the first portion 321. The two splicing portions 3211 limit the first housing 310 from opposite sides, thereby making the first housing 310 and the second housing 320 fit together more tightly.

[0084] like Figure 7 As shown, the opening 310a has a seventh insertion structure 316 on its side away from the first side. (Refer to...) Figure 4 As shown, the splicing part 3211 has an eighth insertion structure 327 at the edge away from the first part 321, and the eighth insertion structure 327 is inserted into the seventh insertion structure 316.

[0085] As an example, the seventh plug-in structure 316 includes a plug-in slot 3160, and the eighth plug-in structure 327 includes a fourth plug-in plate 3270. After the second housing 320 is assembled to the first housing 310, the fourth plug-in plate 3270 is inserted into the plug-in slot 3160.

[0086] The cooperation of the seventh insertion structure 316 and the eighth insertion structure 327 can further restrict the relative positions of the first housing 310 and the second housing 320, for example, restricting the first housing 310 and the second housing 320 in... Figure 3 The relative displacement in the X or Y direction shown improves the stability of the housing assembly and prevents the first housing 310 and the second housing 320 from separating.

[0087] In some examples, the seventh plug structure 316 may include two or more plug slots 3160, and the eighth plug structure 327 may include two or more fourth plug plates 3270 to further improve the stability of the housing assembly.

[0088] Figure 8 This is an assembly diagram of a first housing and a second housing provided in an embodiment of this application. The diagram shows the inner side of the first housing 310. Figure 8 At least a portion of the structure of the first housing 310 and a portion of the structure of the second housing 320 were removed. For example... Figure 8 As shown, the insertion slot 3160 can be located on the inner surface of the first housing 310. The fourth insertion plate 3270 is located at the edge of the splicing portion 3211, and the fourth insertion plate 3270 is close to the inner surface of the splicing portion 3211, which helps to reduce the discontinuity between the outer surface of the splicing portion 3211 and the outer surface of the first housing 310. Here, the inner surface of the splicing portion 3211 refers to the surface of the splicing portion 3211 that is close to the first housing 310.

[0089] like Figure 8As shown, the first housing 310 may further include a limiting protrusion 317, which is located in the opening 310a and outside the insertion groove 3160. After the first housing 310 and the second housing 320 are assembled, the limiting protrusion 317 is located inside the splicing portion 3211 to limit the movement of the first housing 310 and the second housing 320. Figure 3 The relative displacement in the Z direction shown makes the assembly of the first housing 310 and the second housing 320 more stable. As an example, a limiting protrusion 317 may be distributed on each side of the insertion slot 3160.
