[0002] The cover of the product generally has characters and patterns to facilitate the user to identify and use the product, for example, the characters are the names of the corresponding functions, and pressing the patterns can realize the corresponding functions. However, the characters and patterns of the existing product are generally manufactured by silk printing and spray drawing, which results in that the characters and patterns are not clear enough and have burrs and ghosting, and are prone to fading after long-term use, which affects the use of the user. SUMMARY

[0003] Therefore, it is necessary to provide a cover structure and range hood in view of the problem that the characters and patterns of the existing product cover are not clear enough, have burrs and ghosting, and are prone to fading, which affects the use of the user.

[0004] A cover structure comprises a cover assembly, a first plating layer arranged on the cover assembly, a second plating layer provided with a hollow area, the second plating layer being arranged on the first plating layer, the first plating layer being of a first color, the second plating layer being of a second color, a light source assembly arranged on the cover assembly, the light source assembly facing the hollow area, and a control assembly electrically connected with the light source assembly, the control assembly being used to control the opening and closing of the light source assembly.

[0005] The first aspect of the present application discloses a cover structure with patterns, which forms characters and patterns by engraving a hollow area on the second plating layer to expose the first plating layer, thereby avoiding the problem that the characters and patterns are not clear enough and have burrs and ghosting, making the edges of the characters and patterns more sharp and clear, so that the user can more accurately identify the details such as the content of the characters and the shape of the patterns, and fading does not occur after long-term use, which facilitates the operation of the user. Moreover, the first plating layer and the second plating layer are of different colors, and the depth of the hollow area is generally processed to the first plating layer, so that the first plating layer is of the color of the characters and patterns, and the second plating layer is of the color of the product, thereby the characters and patterns are more clear and visible. The opening and closing control of the light source assembly by the control assembly enables the light source assembly to illuminate the characters and patterns, so that the user can well operate the functions of the product at night, and the user experience is good.

[0006] The following are the steps of forming the characters and patterns of the product: S1, the first time of spraying primer is red to form the first plating layer; S2, the second time of spraying primer is black to form the second plating layer; S3, using a laser machine to engrave through the second plating layer to form characters or patterns, the characters or patterns being of the color of the first plating layer.

[0007] In one of the embodiments, a coating layer is further included, which is arranged on the second plating layer and covers the hollowed-out areas. The coating layer is arranged to make the outer side of the product front cover flush and have a high appearance quality.

[0008] In one of the embodiments, the coating layer is UV paint or PU paint. The coating layer is UV paint or PU paint and transparent, which makes the product appearance smoother and has a high appearance quality. This design does not affect the clear display of the patterns.

[0009] In one of the embodiments, a light shielding member is further included, which is arranged on the cover assembly and / or the light source assembly, is located between the cover assembly and the light source assembly, and is provided with a light channel extending towards the direction of the hollowed-out areas. The light channel of the light shielding member extending towards the direction of the hollowed-out areas can guide the light to be concentrated on the areas to be displayed and avoid the light scattering to other directions.

The first opening is closed by the light source assembly, the second opening is closed by the cover assembly, and the first opening and the second opening are in communication with the light channel, which can ensure that the light emitted by the light source assembly propagates in the light channel and realizes accurate light guiding. This design effectively prevents the light from leaking out of the two ends of the light channel, reduces light scattering, ensures that the light energy is concentrated in the predetermined area, and enhances the stability of the text and pattern display effect.

[0011] In one of the embodiments, the second plating layer forms a plurality of hollowed-out areas, the plurality of hollowed-out areas are arranged in sequence along the length direction of the cover assembly, the number of the light shielding members is the same as that of the hollowed-out areas, the light shielding members extend towards the hollowed-out areas one by one, and the light shielding members and the hollowed-out areas are respectively located on two sides of the cover assembly. The plurality of hollowed-out areas are arranged in sequence along the length direction of the cover assembly, and the same number of light shielding members extend towards the hollowed-out areas one by one, which makes the text form an orderly arrangement in vision. When the light passes through the light shielding member and shines on the hollowed-out area, the text will be more prominent and eye-catching, which enhances the overall visual effect of the text and helps to better convey the relevant information of the product.

[0012] In one of the embodiments, the light shielding member comprises a light shielding sleeve and a clamping member, the light shielding sleeve is arranged on the light source assembly, the light shielding sleeve is provided with the light channel, the clamping member is arranged on the light shielding sleeve and located on the side of the light shielding sleeve facing the light source assembly, and the clamping member is clamped with the light source assembly.

Moreover, the installation of the light shielding member is more firm and reliable.

[0013] In one of the embodiments, the light source assembly is provided with clamping holes, the number of the clamping holes is multiple, the multiple clamping holes are sequentially arranged along the length direction of the light source assembly, and the clamping member is matched with the clamping holes. By sequentially arranging the multiple clamping holes along the length direction of the light source assembly and matching the clamping member with the clamping holes, the installation position of the light shielding member on the light source assembly can be accurately determined. This design ensures that the light channel is accurately directed to the direction of the text and / or pattern, avoids the light from not accurately irradiating the predetermined area due to the installation position deviation, and improves the accuracy of light management.
