[0025] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0026] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0027] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0028] In related art, to facilitate users to intuitively receive information about the remaining liquid storage or battery level of the atomizer, a display screen can be provided on the atomizer. To conserve power, the display screen can be set to illuminate when in use and to be dimmed when not in use. One approach is to make the atomizer housing a black, translucent piece. This allows the housing's exterior color to remain consistent when the display screen is off. However, this results in the atomizer housing being restricted to black, resulting in a single color for the atomizer product, which is not conducive to product diversification and reduces market competitiveness.

[0029] See also Figures 1 to 4 The embodiment of the present application provides a display housing of an atomizing device, including a housing 1, a light-transmitting layer 3, and other functional components that may exist as needed, which are described in detail below.

[0030] like Figure 1-Figure 3 、 Figure 7 As shown, the outer surface of the housing 1 in this embodiment is provided with a concavo-convex texture structure 202, and the housing 1 is provided with a transparent display area 201, which is used to correspond to the display screen 6 located in the housing 1. The light-transmitting layer 3 is non-transparent and covers the texture structure 202. The light-transmitting layer 3 is a paint material and is covered on the texture structure 202 by spraying paint.

[0031] It is understood that transparency in this embodiment means that the material allows light to pass through completely without significant attenuation or change of direction; opaque means that the material allows part of the light to pass through; and translucent means that the translucent layer 3 allows light to pass through. Therefore, both the transparent display area 201 and the opaque translucent layer 3 allow light emitted from the display screen 6 in the housing 1 to pass through, thereby realizing the display function of the display housing 1. This embodiment does not impose any specific restrictions on the material of the housing 1, and any transparent material can be used. Figure 2 、 Figure 3As shown, the texture structure 202 in this embodiment is a tiny structure on the outer surface of the shell 1, which can make the outer surface of the shell 1 appear rough. When touched, it can feel rough but there will be no obvious bumps. The light-transmitting layer 3 covers the texture structure 202. Because the texture structure 202 is concave and convex, it is beneficial for the light-transmitting layer 3 to better adhere or stick to the outer surface of the shell 1, and the light-transmitting layer 3 is not easy to fall off. The display area 201 in this embodiment is the area on the shell 1 corresponding to the position of the display screen 6, so that the light emitted by the display screen 6 can pass through the display area 201, realizing the luminescence of the display shell 1. The light-transmitting layer 3 in this embodiment covers the display area 201 and other areas on the shell 1 except the display area 201, that is, the outer surface of the shell 1 is covered with the light-transmitting layer 3 as a whole. The overall coverage is beneficial to improving the consistency of the appearance color of the shell when the display screen 6 is not displayed.

[0032] In one embodiment, the light-transmitting layer 3 is a paint material, and the light-transmitting layer 3 is applied to the texture structure 202 by spraying. Spraying paint is simple and quick to produce, which helps reduce the processing cost of the atomizing device and shortens the processing cycle of the atomizing device. Furthermore, the light-transmitting layer 3 applied to the texture structure 202 by spraying paint has good adhesion and is not easily detached, which facilitates the long-term use of the atomizing device. Spraying paint allows for the color of the exterior to be changed at low cost and very conveniently. Using different colors of paint can achieve different color effects, and by spraying different paints at different locations, a multicolored exterior can also be achieved. Furthermore, the light-transmitting layer 3 formed by spraying paint is thinner, and a thinner light-transmitting layer 3 has better light transmittance, resulting in clearer edges of images or text, and improving halation of images or text. In some application scenarios, the light-transmitting layer 3 can also be formed on the outer surface of the housing 1 by a coating process, or the light-transmitting layer 3 can be made of other materials and processes. For example, the light-transmitting layer 3 can be a thin, colored plastic film layer, which is attached to the outer surface of the housing 1 by a laminating process, which also achieves light transmission.

[0033] The display housing of the atomizing device provided in this embodiment includes a housing 1 and a light-transmitting layer 3. The outer surface of the housing 1 is provided with a concave-convex texture structure 202. The housing 1 is provided with a transparent display area 201, which is used to correspond to the display screen 6 located within the housing 1. The non-transparent light-transmitting layer 3 covers the texture structure 202. The light-transmitting layer 3 is a paint material and is covered by spraying paint on the texture structure 202. This helps to improve the consistency of the outer color of the housing when the display screen 6 is not displayed. The outer color of the product can be changed by changing the color of the light-transmitting layer 3. The appearance of the product can also be changed by changing different texture structures 202. This facilitates the diversified design of atomizing device products and improves their market competitiveness.

[0034] In one embodiment, the texture structure 202 may include a plurality of raised or recessed stripe structures. The stripe structures in this embodiment are micro structures on the outer surface of the housing 1. The shapes and sizes of the stripe structures may be consistent or inconsistent, and the stripe structures may be evenly distributed or unevenly distributed. In one embodiment, as Figure 2 As shown, the texture structure 202 may also include a plurality of independent circular arc shaped convex structures. The convex structure in this embodiment is also a tiny structure on the outer surface of the shell 1. The circular arc shaped convex structure has a divergent effect on the light, which is beneficial to improving the uniformity of the light emission. In some application scenarios, the texture structure 202 may also be other tiny structures with other concave-convex shapes, or the texture structure 202 may also have the above-mentioned striped structure, circular arc shaped convex structure, and other tiny structures at the same time, which can be set as needed. When the texture structure 202 is a striped structure, the display housing 1 can be presented in one appearance. When the texture structure 202 is a circular arc shaped convex structure, the display housing 1 can be presented in another appearance. By replacing different texture structures 202, the appearance of the display housing 1 can be changed, which is beneficial to the diversified design of the atomizing device product.

[0035] In one embodiment, when the light-transmitting layer 3 is covered on the texture structure 202 by spraying paint, the thickness of the light-transmitting layer 3 may be 20 μm-40 μm. By controlling the thickness of the paint layer, not only can the light transmittance of the light-transmitting layer 3 be achieved, but it is also beneficial to improve the consistency of the appearance color of the shell when the display screen 6 is not displayed. In some application scenarios, when the requirements for the color consistency of the shell are not high, the thickness of the light-transmitting layer 3 may also be less than 20 μm, or when the brightness of the display screen 6 is high, the thickness of the light-transmitting layer 3 may also be greater than 40 μm. When the light-transmitting layer 3 is made of materials other than paint materials, the thickness of the light-transmitting layer 3 can be set as needed to achieve the light transmittance of the light-transmitting layer 3.

[0036] In one embodiment, the housing 1 and the textured structure 202 thereon are integrally injection-molded from a transparent material, and the textured structure 202 is integrally injection-molded onto the outer surface of the housing 1. The housing 1 in this embodiment is made of transparent plastic. The housing 1 integrally injection-molded from the transparent material is transparent as a whole, that is, the display area 201 and other areas outside the display area 201 are all transparent. In this case, the color consistency of the display housing 1 is higher, and the manufacturing process is simple, which helps to reduce processing costs. In some embodiments, only the display area 201 can be made of a transparent material, and other areas on the housing 1 can be made of a non-transparent material, as long as the display area 201 can display well.

[0037] In one embodiment, Figure 4As shown, the inner side of the housing 1 is provided with a groove 203 for accommodating the display screen 6. The bottom of the groove 203 is designed to contact the display surface of the display screen 6. Providing the groove 203 on the inner side of the housing 1 can reduce the thickness of the housing 1, which is beneficial for improving the display effect. The bottom of the groove 203 contacts the display surface of the display screen 6, which helps prevent impurities from entering between the housing 1 and the display screen 6 and affecting the luminous display. The lack of a gap between the housing 1 and the display screen 6 also helps reduce diffuse reflection and improve the display effect. The display surface of the display screen 6 contacts the bottom of the groove 203, that is, the display surface of the display screen 6 is located within the groove 203. In this case, when impurities such as water or dust enter the display surface of the display screen 6, they must pass through the gap between the groove wall of the groove 203 and the side wall of the display screen 6 to enter. This extends the impurity entry path and also helps prevent impurities from entering between the housing 1 and the display screen 6 and affecting the luminous display. In some application scenarios, the groove 203 can be omitted as needed, and the display surface of the display screen 6 can be directly attached to the inner surface of the housing 1.

[0038] The display housing of the atomizing device provided in the above embodiment includes a housing 1 and a light-transmitting layer 3. The outer surface of the housing 1 is provided with a concave-convex texture structure 202. The housing 1 is provided with a transparent display area 201, which is used to correspond to the display screen 6 located within the housing 1. The non-transparent light-transmitting layer 3 covers the texture structure 202. The light-transmitting layer 3 is a paint material and is covered by spraying paint on the texture structure 202. This helps to improve the consistency of the outer color of the housing when the display screen 6 is not displayed. The product's appearance color can be changed by changing the color of the light-transmitting layer 3. The product's appearance can also be changed by changing different texture structures 202. This facilitates the diversified design of atomizing device products and improves their market competitiveness.

[0039] See also Figure 5 The present application also provides a method for manufacturing a display housing of the atomizing device as described above, comprising the following steps:

[0040] S1: forming a shell having a textured structure.

[0041] The structure of the housing 1 in this embodiment can be the same as that of the above embodiment. The housing 1 in this embodiment can be made of transparent plastic and formed in one piece through an injection molding process. The texture structure 202 is formed on the outer surface of the housing 1 through one piece injection molding. The housing 1 formed by one piece injection molding of transparent material is transparent as a whole, that is, the display area 201 and other areas outside the display area 201 are transparent. In this case, the appearance color consistency of the display housing 1 is higher, and the production is simple, which helps to reduce processing costs. In some embodiments, only the display area 201 can be made of transparent material, and other areas on the housing 1 can be made of non-transparent material, as long as the display area 201 can display well.

[0042] S2: forming a light-transmitting layer covering the texture structure on the outer surface of the shell through a painting process.

[0043] Among them, the light-transmitting layer covers the display area and other areas on the shell except the display area. The production of spray painting is simple and quick, which is conducive to reducing the processing cost of the atomizing device and shortening the processing cycle of the atomizing device. The light-transmitting layer 3 covered on the texture structure 202 by spray painting has good adhesion and is not easy to fall off, which is conducive to the long-term use of the atomizing device. In one embodiment, the thickness of the spray paint can be 20μm-40μm. By controlling the thickness of the paint layer, not only can the light transmittance of the light-transmitting layer 3 be achieved, but it is also conducive to improving the consistency of the appearance color of the shell when the display screen 6 is not displayed.

[0044] In the method for manufacturing the display housing of the atomizing device provided in the above embodiment, a housing 1 and a light-transmitting layer 3 covering the housing 1 are formed. The outer surface of the housing 1 is provided with a concave-convex texture structure 202. The housing 1 is provided with a transparent display area 201. The display area 201 is used to correspond to the display screen 6 located in the housing 1. The non-transparent light-transmitting layer 3 covers the texture structure 202. The light-transmitting layer 3 is a paint material and is covered on the texture structure 202 by spraying paint. This is conducive to improving the consistency of the outer color of the housing when the display screen 6 is not displayed. The outer color of the product can be changed by changing the color of the light-transmitting layer 3. The appearance of the product can also be changed by changing different texture structures 202. This is conducive to the diversified design of atomizing device products and improves market competitiveness.

[0045] See also Figures 6 to 8 The embodiment of the present application also provides an atomization device, including a display screen 6, a liquid storage component 7, an atomization component 8, and a display shell of the atomization device as described above. The display screen 6, the liquid storage component 7, and the atomization component 8 are all arranged in the shell 1. The display surface of the display screen 6 corresponds to the display area 201. The liquid storage component 7 is used to store the atomization matrix, and the atomization component 8 is used to heat the atomization matrix to form an aerosol.

[0046] It is understandable that the display housing of the atomizing device in this embodiment may be the same as that in the above-mentioned embodiment, and will not be described in detail here. In this embodiment, a suction nozzle 5 may be provided at one end of the housing 1, and a bottom cover 4 may be provided at the other end. The liquid storage part 7 in this embodiment is used to store the atomizing matrix, and the atomizing matrix may be a medicinal liquid, an e-liquid, or other liquid matrix that can be atomized. The atomizing assembly 8 is used to heat the atomizing matrix to form an aerosol, and the atomizing assembly 8 includes but is not limited to a heating element. The atomizing device in this embodiment may also include other structures or components, such as a battery 9 and a circuit board, and the circuit board is electrically connected to the display screen 6, the battery 9, and the atomizing assembly 8, respectively.

[0047] In one embodiment, Figure 7、 Figure 8 As shown, the display screen 6 can be arranged between the liquid storage part 7 and the shell 1. A positioning rib 701 is provided on the side of the liquid storage part 7 corresponding to the display area 201 on the shell 1. The positioning rib 701 is used to position at least one side of the display screen 6. The positioning rib 701 can mark the installation position of the display screen 6, which is convenient for assembly. The positioning rib 701 can also limit the assembly space of the display screen 6, which is convenient for preventing the display screen 6 from shifting. In some embodiments, when the suction nozzle 5 is provided at one end of the shell 1 and the bottom cover 4 is provided at the other end, the end of the bottom cover 4 can be opposite to one side of the display screen 6 to limit the side of the display screen 6. The other three sides of the display screen 6 are respectively provided with a positioning rib 701, and the positioning ribs 701 on the other three sides are all provided on the liquid storage part 7. In some application scenarios, the positioning rib 701 can also be provided on other components or structures in the shell 1, or the positioning rib 701 can be omitted as needed.

[0048] In one embodiment, a groove 203 for accommodating a display screen 6 is provided on the inner side of the shell 1. The display screen 6 is a flexible display screen 6. The flexible display screen 6 is fixed to the liquid storage part 7 by means of foam glue, and the flexible display screen 6 is pressed against the bottom of the groove 203 by means of foam glue, so that the display surface of the display screen 6 is in contact with the shell 1. The flexible display screen 6 has a deformable ability and can adapt to both flat and curved displays, so that both the curved and flat parts of the shell 1 can be used as the display area 201, which expands the space in which the display area 201 can be arranged on the shell 1, and is conducive to improving the diversified design of the product. The foam glue in this embodiment has bonding and deformation capabilities. The foam glue can be a double-sided tape, with one side of the foam glue bonded to the display screen 6 and the other side bonded to the liquid storage part 7, thereby fixing the display screen 6 in the shell 1. The distance between the display screen 6 and the liquid storage member 7 can be less than the thickness of the foam adhesive when not in use. After assembly, the foam adhesive will be squeezed, and the squeezed foam adhesive can press the display screen 6 against the bottom of the groove 203, so that the display surface of the display screen 6 contacts the housing 1, improving the display effect. In some application scenarios, the display screen 6 can also be a non-flexible display screen 6, and the display screen 6 can also be fixed in the housing 1 by other connection methods, such as screws.

[0049] The atomizing device provided in the above embodiment includes a housing 1 and a light-transmitting layer 3. The outer surface of the housing 1 is provided with a concave-convex texture structure 202. The housing 1 is provided with a transparent display area 201, which is used to correspond to the display screen 6 located within the housing 1. The non-transparent light-transmitting layer 3 covers the texture structure 202. The light-transmitting layer 3 is a paint material and is covered by spraying paint on the texture structure 202. This helps to improve the consistency of the outer shell's appearance color when the display screen 6 is not displayed. The appearance color of the product can be changed by changing the color of the light-transmitting layer 3. The appearance of the product can also be changed by changing different texture structures 202. This facilitates the diversified design of atomizing device products and improves market competitiveness.

[0050] The above examples are used to illustrate the present application, which are only used to help understand the present application and are not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
