AI Technical Summary
[0003]本申请提供一种雾化装置，能解决雾化装置的主壳体与装饰壳因制造公差大造成装配后配合间隙不稳定的问题
[0014]该雾化装置通过在主壳体上设置安装槽，装饰壳和安装槽通过凸筋和凹槽配合，由于凸筋和凹槽均为大尺寸的壳上的小尺寸结构，小尺寸的凸筋和凹槽之间的制造公差可精确控制，例如凸筋宽度设计若为2-3mm，其公差可控制在正负0.05mm范围内，而大尺寸的主壳体的整体尺寸的公差可达0.5mm，可见，凸筋的公差控制远小于壳体整体尺寸的公差控制。装配时，凸筋卡入凹槽中，无论装饰壳整体尺寸是否因负公差缩小，凹槽和凸筋均遵循小尺寸的更小的公差，不会随装饰壳整体负公差同步缩小，若装饰壳因整体负公差继续试图缩小与主壳体的间隙，凹槽的内壁会被凸筋的外壁挡住，使得装饰壳无法继续偏移，直接限制了装饰壳的可偏移空间，避免了额外空隙的产生。传统结构中，由于缺乏凸筋-凹槽的限位，装饰壳可自由偏移，无任何结构阻挡；而本申请通过凸筋和凹槽的小尺寸精准配合，将装饰壳的偏移空间从无限制变为被凸筋和凹槽的配合严格限定，本质是用局部小尺寸的精准控制弥补了整体大尺寸负公差的缺陷，最终从结构层面解决了传统设计中间隙无限制扩大的问题。

Description
Technical Field
[0001] This application relates to the field of atomization technology, specifically to an atomization device. Background Technology
[0002] In the manufacturing of atomizing devices, controlling the assembly clearance between housings has a crucial impact on the overall quality and appearance of the product. Currently, the main housing and decorative housing, as core appearance components of atomizing devices, often need to be designed with relatively large dimensions to meet the overall shape and functional requirements of the device. However, as the size of the parts increases, the tolerances in the manufacturing process often expand accordingly. Relying solely on the natural fit of the parts' external dimensions, when the dimensions at the main housing's mating point are within the positive tolerance range and the corresponding dimensions of the decorative housing are within the negative tolerance range, the main housing lacks effective constraint on the decorative housing. The clearance between the two will significantly exceed the design standards, resulting in unstable mating clearances. This severely compromises the atomizing device's appearance regularity and reduces the product's visual quality. Utility Model Content
[0003] This application provides an atomizing device that can solve the problem of unstable fit clearance between the main housing and decorative housing after assembly due to large manufacturing tolerances.
[0004] To address the aforementioned technical problems, this application provides an atomizing device, comprising a main housing and a decorative shell.

The inner side of the decorative shell faces the bottom of the groove, the outer side of the decorative shell faces away from the bottom of the groove, the transition surface faces the side of the groove, the side of the groove is used to limit the transition surface, the side of the groove includes a first inclined surface, the transition surface includes a second inclined surface, and the first inclined surface faces the second inclined surface. One of the bottom surface and the inner surface of the groove is provided with a raised rib, and the other is provided with a groove. The raised rib is inserted into the groove.
[0005] In one embodiment, the number of ribs and grooves is at least two, the main housing has a central axis, and the atomizing device has a first side and a second side opposite to each other along the direction of the central axis. A portion of the ribs and a portion of the grooves are disposed near the first side, and another portion of the ribs and another portion of the grooves are disposed near the second side.
[0006] In one embodiment, each rib has a consistent shape, each groove has a consistent shape, the ribs are spaced apart and aligned along the central axis, and the grooves are spaced apart and aligned along the central axis.
[0007] In one embodiment, both the ribs and the grooves are strip-shaped structures.
[0008] In one embodiment, the length extension direction of both the rib and the groove is perpendicular to the central axis of the main housing.
[0009] In one embodiment, the bottom surface of the tank includes a first bottom surface, a second bottom surface, and a third bottom surface that are sequentially connected along the circumferential direction of the main housing. The first bottom surface and the third bottom surface are disposed opposite to each other and are connected by the second bottom surface. The inner surface includes a first side, a second side, and a third side connected sequentially along the circumferential direction of the main housing. The first side and the third side are arranged opposite to each other and are connected by the second side. One of the second side and the second bottom surface is provided with a rib, and the other is provided with a groove.
[0010] In one embodiment, the groove side surface further includes a fourth side surface and a fifth side surface, the fourth side surface, the first inclined surface and the fifth side surface are connected sequentially along the circumferential direction of the main housing; the angle between the normal of the first inclined surface and the normal of the second bottom surface is not perpendicular, the transition surface includes a sixth side surface and a seventh side surface, the sixth side surface, the second inclined surface and the seventh side surface are connected sequentially along the circumferential direction of the main housing, the angle between the normal of the second inclined surface and the normal of the second side surface is not perpendicular.
[0011] In one embodiment, a first mounting hole is provided on the bottom surface of the groove, and a second mounting hole is provided on the decorative shell. The second mounting hole penetrates the inner side and the outer side. The first mounting hole and the second mounting hole are arranged opposite to each other. The atomizing device also includes a fastener that passes through the second mounting hole and is threadedly connected to the first mounting hole.
[0012] In one embodiment, a first viewing window is provided on the bottom surface of the groove, and a second viewing window is provided on the decorative shell, which penetrates the decorative shell. The first viewing window and the second viewing window are arranged opposite to each other, and the first viewing window is connected to the assembly space and the second viewing window.
[0013] In one embodiment, a protruding ring is provided on the inner side, the protruding ring surrounds to form a second window, the protruding ring extends into the first window and abuts against the inner wall of the first window.
[0014] This atomizing device features a mounting groove on the main housing. The decorative shell and the mounting groove are fitted together by ribs and grooves. Since both the ribs and grooves are small-sized structures on a large-sized shell, the manufacturing tolerances between the small ribs and grooves can be precisely controlled. For example, if the width of the rib is designed to be 2-3mm, its tolerance can be controlled within ±0.05mm, while the overall dimensional tolerance of the large-sized main housing can reach 0.5mm. Therefore, the tolerance control of the rib is much smaller than the tolerance control of the overall housing dimension. During assembly, the rib engages with the groove. Regardless of whether the overall dimension of the decorative shell shrinks due to negative tolerance, the groove and rib follow the smaller tolerance of the smaller dimensions and will not shrink synchronously with the overall negative tolerance of the decorative shell. If the decorative shell continues to attempt to reduce the gap with the main housing due to the overall negative tolerance, the inner wall of the groove will be blocked by the outer wall of the rib, preventing the decorative shell from shifting further. This directly limits the offset space of the decorative shell and avoids the generation of additional gaps. In traditional structures, due to the lack of ribs and grooves for restraint, the decorative shell can shift freely without any structural obstruction. However, this application, through the precise matching of small dimensions of the ribs and grooves, changes the unrestricted offset space of the decorative shell to one that is strictly limited by the matching of the ribs and grooves. Essentially, it uses precise control of small local dimensions to compensate for the defects of negative tolerance of large overall dimensions, and ultimately solves the problem of unlimited expansion of gaps in traditional designs from a structural perspective.

Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.
[0021] Please refer to Figure 1-5 This application provides an atomizing device, which includes a main housing 10 and a decorative housing 20. Furthermore, the atomizing device may also include an atomizing component, which includes a support, an atomizing core, and other structures. The support is used to fix the atomizing core, and the atomizing core is used to heat and atomize the atomizing substrate to generate an aerosol.
[0022] The main housing 10 has an assembly space 11 for assembling atomizing components. An installation groove 12 is formed on the outer wall of the main housing 10. The installation groove 12 has a bottom surface 121 and a side surface 122. Specifically, the side surface 122 extends approximately along the depth direction of the installation groove 12, the opening of the installation groove 12 faces outward, and the bottom surface 121 is the surface opposite to the opening of the installation groove 12.
[0023] like Figure 1 and Figure 2 As shown, at least a portion of the decorative shell 20 is disposed within the mounting groove 12 and fixedly connected to the main shell 10. Specifically, the shape of the decorative shell 20 is approximately consistent with the shape of the mounting groove 12. Figure 4 and Figure 5 As shown, the decorative shell 20 has an inner side 21, an outer side 22, and a transition surface 23 connecting the inner side 21 and the outer side 22. The inner side 21 of the decorative shell 20 faces the main shell 10, and the outer side 22 faces away from the main shell 10. That is, the inner side 21 of the decorative shell 20 faces and fits against the bottom surface 121 of the groove, the outer side 22 of the decorative shell 20 faces away from the bottom surface 121 of the groove, and the transition surface 23 faces the side surface 122 of the groove. Figure 3 As shown, the groove side surface 122 can be used to limit the transition surface 23. When the decorative part has a positive tolerance, the groove side surface 122 will press against the transition surface 23 of the decorative part, thus confining the decorative part within the mounting groove 12. Specifically, the groove side surface 122 includes a first inclined surface 1221, and the transition surface 23 includes a second inclined surface 231. The first inclined surface 1221 is set towards the second inclined surface 231. The inclination direction and degree of the first inclined surface 1221 and the second inclined surface 231 are the same. The first inclined surface 1221 and the second inclined surface 231 also have a guiding function during assembly. During assembly, the second inclined surface 231 of the decorative shell 20 can naturally slide into the mounting groove 12 along the inclination direction of the first inclined surface 1221, greatly reducing the difficulty of assembly operation.
[0024] like Figure 3-5As shown, one of the bottom surface 121 and the inner surface 21 of the groove is provided with a raised rib 30, and the other is provided with a groove 40. The raised rib 30 is inserted into the groove 40. The atomizing device is provided with a mounting groove 12 on the main housing 10. The decorative shell 20 and the mounting groove 12 are connected by the raised rib 30 and the groove 40. Since the raised rib 30 and the groove 40 are small-sized structures on a large-sized shell, the manufacturing tolerance between the small-sized raised rib 30 and the groove 40 can be precisely controlled. This is because various errors in the production process of large-sized parts (such as uneven temperature distribution of injection molds, fluctuation of injection pressure, uneven cooling shrinkage of parts, etc.) will accumulate and superimpose as the size range increases. However, the error accumulation space in the manufacturing process of small-sized structures is small. For example, if the width of the raised rib 30 is designed to be 2-3mm, its tolerance can be controlled within the range of ±0.05mm, while the overall size tolerance of the large-sized main housing 10 can reach 0.5mm. It can be seen that the tolerance control of the raised rib 30 is much smaller than the tolerance control of the overall size of the housing.
[0025] During assembly, the rib 30 engages with the groove 40. Regardless of whether the overall size of the decorative shell 20 is reduced due to negative tolerance, both the groove 40 and the rib 30 adhere to the tolerance precision of small dimensions and will not shrink synchronously with the overall negative tolerance of the decorative shell 20. If the gap between the decorative shell 20 and the main shell 10 shrinks due to the overall negative tolerance, the inner wall of the groove 40 will be blocked by the outer wall of the rib 30, preventing the decorative shell 20 from shifting further. This directly limits the offset space of the decorative shell 20 and avoids the generation of additional gaps. In traditional structures, due to the lack of the limiting effect of the rib 30 and the groove 40, the decorative shell 20 can shift freely without any structural obstruction. However, this application, through the precise fit of the rib 30 and the groove 40 with small dimensions, changes the offset space of the decorative shell 20 from unlimited to strictly limited by the fit of the rib 30 and the groove 40. Essentially, it uses the precise control of local small dimensions to compensate for the defects of the overall large-dimensional negative tolerance, ultimately solving the problem of unlimited gap expansion in traditional designs from a structural perspective.
[0026] In one embodiment, such as Figure 4 and Figure 5 As shown, the number of ribs 30 and grooves 40 is at least two, such as Figure 1 As shown, the main housing 10 has a central axis. Figure 1 The dashed line in the diagram illustrates the central axis of the main housing 10. Specifically, the line connecting the midpoint of the top of the main housing 10 and the midpoint of the bottom of the main housing 10 can coincide with the position of the central axis. Generally, the central axis of the main housing 10 is parallel to the height direction of the main housing 10. The top is usually where the nozzle of the atomizing device is located.
[0027] The atomizing device has opposing first and second sides along the direction of the central axis, for example, in Figure 1In the middle, the first side is the top side, and the second side is the bottom side. A portion of the protruding ribs 30 and a portion of the grooves 40 are positioned near the first side, while other portions of the protruding ribs 30 and other portions of the grooves 40 are positioned near the second side. For example, in... Figure 4 and Figure 5 In this embodiment, there are three ribs 30 and three grooves 40. One rib 30 and one groove 40 are located on the top side, and the other two ribs 30 and the other two grooves 40 are located on the bottom side. Each cooperating rib 30 and groove 40 can correct the misalignment and work together to solve the problem of unstable mating clearance.
[0028] In one embodiment, each rib 30 has a consistent shape, and each groove 40 has a consistent shape. The ribs 30 are spaced apart and aligned along the central axis, and the grooves 40 are spaced apart and aligned along the central axis. This ensures that after assembly, the engagement force between each rib 30 and groove 40 is essentially the same, the force direction is relatively uniform, and when the ribs 30 engage with the grooves 40, the direction in which each rib 30 engages with the groove 40 is consistent, further facilitating smoother assembly.
[0029] In one embodiment, both the rib 30 and the groove 40 are strip-shaped structures. The longer mating surface of the strip-shaped structure avoids structural deformation caused by excessive local stress and enhances the reliability of the fit between the rib 30 and the groove 40. In another embodiment, the length extension direction of both the rib 30 and the groove 40 is perpendicular to the central axis of the main housing 10. That is, the rib 30 can be a transverse rib, and the groove 40 can be a transverse groove.
[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the bottom surface 121 of the tank includes a first bottom surface 1211, a second bottom surface 1212 and a third bottom surface connected sequentially along the circumferential direction of the main housing 10. The first bottom surface 1211 and the third bottom surface are arranged opposite to each other and are connected by the second bottom surface 1212. The first bottom surface 1211, the second bottom surface 1212 and the third bottom surface generally enclose a U-shaped surface.
[0031] The inner surface 21 includes a first side surface, a second side surface 212, and a third side surface 213 connected sequentially along the circumferential direction of the main shell 10. The first side surface and the third side surface 213 are arranged opposite to each other and connected by the second side surface 212. They have the same shape as the first bottom surface 1211, the second bottom surface 1212, and the third bottom surface, and the first side surface, the second side surface 212, and the third side surface 213 generally form a U-shaped surface. The first side surface has the same shape as the first bottom surface 1211 and they abut against each other. The second bottom surface 1212 has the same shape as the second side surface 212 and they abut against each other. The third bottom surface and the third side surface 213 have the same shape and they abut against each other. One of the second side surface 212 and the second bottom surface 1212 is provided with a protruding rib 30, and the other is provided with a groove 40. That is, the protruding rib 30 and the groove 40 are provided on the surface in the width direction of the shell.
[0032] In one embodiment, the groove side surface 122 further includes a fourth side surface 1222 and a fifth side surface 1223, which are sequentially connected along the circumferential direction of the main housing 10. The angle between the normal of the first inclined surface 1221 and the normal of the second bottom surface 1212 is not perpendicular. The transition surface 23 includes a sixth side surface 232 and a seventh side surface 233, which are sequentially connected along the circumferential direction of the main housing 10. The angle between the normal of the second inclined surface 231 and the normal of the second side surface 212 is not perpendicular. Specifically, the fourth side surface 1222 is connected to the first bottom surface 1211, the first inclined surface 1221 is connected to the second bottom surface 1212, and the fifth side surface 1223 is connected to the third bottom surface; the first side surface is connected to the sixth side surface 232, the second inclined surface 231 is connected to the second side surface 212, and the third side surface 213 is connected to the seventh side surface 233. That is, the first inclined surface 1221 and the second inclined surface 231 are also provided on the surface of the shell in the width direction.
[0033] In one embodiment, a first viewing window 1213 is also provided on the bottom surface 121 of the groove, and a second viewing window 24 is provided on the decorative shell 20, which penetrates the decorative shell 20. The first viewing window 1213 and the second viewing window 24 are arranged opposite to each other. The first viewing window 1213 is connected to both the assembly space 11 and the second viewing window 24. By setting the first viewing window 1213 and the second viewing window 24, the amount of atomizing matrix in the assembly space 11 can be observed from the outside of the decorative shell 20, so as to prompt the user on the amount of atomizing matrix used.
[0034] In one embodiment, such as Figure 4As shown, a protruding ring 25 is provided on the inner side 21, forming a second viewing window 24. The protruding ring 25 extends into the first viewing window 1213 and abuts against the inner wall of the first viewing window 1213. Preferably, the thickness of the protruding ring 25 is the same as the depth of the first viewing window 1213, thereby allowing the protruding ring 25 to be engaged within the first viewing window 1213, thus increasing the stability of the fit between the decorative part and the main housing 10.
[0035] In one embodiment, such as Figure 4 and Figure 5 As shown, a first mounting hole 1214 is provided on the bottom surface 121 of the groove, and a second mounting hole 26 is provided on the decorative shell 20. The second mounting hole 26 penetrates the inner side surface 21 and the outer side surface 22. The first mounting hole 1214 and the second mounting hole 26 are arranged opposite to each other. The atomizing device also includes a fastener 50, which passes through the second mounting hole 26 and is threadedly connected to the first mounting hole 1214. The fastener 50 can be, for example, a screw or other threaded component. By setting the threaded component to fasten the main shell 10 and the decorative component, the main shell 10 and the decorative component can be stably fixed, preventing relative movement between the decorative component and the main shell 10.
