Technical Field
[0001] This utility model relates to the field of beauty instrument technology, and in particular to a beauty instrument with an improved button structure. Background Technology
[0002] In traditional light-colored beauty devices, the light-shielding component in the button module is usually made of a single dark-colored material to prevent light leakage. For example, Chinese utility model patent CN219110661U discloses a beauty device comprising: a housing with an opening and a receiving cavity, the receiving cavity housing a circuit board; a light-emitting component disposed on and electrically connected to the circuit board; and a light-guiding structure disposed at the opening and opposite to the light-emitting component. The light-guiding structure includes a light-shielding component and a light-guiding component, the light-guiding component being sleeved on the light-shielding component, and the light-guiding component and the light-shielding component forming the light-guiding structure through two-color injection molding. This improves waterproofing and increases the assembly efficiency of the beauty device.
[0003] The aforementioned existing technology uses a single light-shielding component, which is generally made of a darker color such as black to achieve the light-shielding effect. If the beauty device adopts an overall design of light color such as white, the color of the light-shielding component can easily show through the light-colored shell, causing the appearance of the beauty device to appear dark in some areas or produce color differences, which seriously limits the design freedom of light-colored beauty devices. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a beauty device with an improved button structure. It uses a double-layer light-shielding component, in which a dark-colored light-shielding component serves as the main light-shielding layer on the inner layer to make the text or pattern clear, while the outer layer is a light-colored light-shielding component.
[0005] This utility model provides a beauty device with an improved button structure, including a beauty device body and a button module. The beauty device body has an inner shell inside, and the front side of the inner shell has a button mounting position. The button module is installed in the button mounting position.
[0006] The button module includes a button circuit board connected to the inner side of the button mounting position, arranged sequentially from the inside to the outside; a light-emitting element disposed on the button circuit board and electrically connected to the button circuit board; a receiving element installed on the outer side of the button mounting position; and a key body connected to the receiving element. The button circuit board is provided with a plurality of key positions.
[0007] The receiving component includes a soft rubber part connected to the key and a light guide part covering the light-emitting element. Between the key body and the light guide part of the receiving component, there are dark light-shielding parts and light light-shielding parts stacked sequentially from the inside to the outside.
[0008] In one of the alternative technical solutions, the dark-colored light-shielding component and the light-colored light-shielding component are respectively provided with light-transmitting patterns of the same shape, and the area of the light-transmitting pattern on the light-colored light-shielding component is larger than the area of the light-transmitting pattern on the dark-colored light-shielding component.
[0009] In one of the alternative technical solutions, the surfaces of both the dark-colored and light-colored light-shielding components have a base coat and a color coat layer stacked sequentially from the inside out, and the light-transmitting pattern is formed on the color coat layer by laser engraving.
[0010] In one of the alternative technical solutions, the paint layer on the dark-colored light-shielding component is black, and the paint layer on the light-colored light-shielding component is white.
[0011] In one of the alternative technical solutions, the dark-colored light-shielding member is fixedly bonded to the outer periphery of the light-colored light-shielding member.
[0012] In one of the alternative technical solutions, the dark-colored light-shielding component and the light-colored light-shielding component are respectively provided with a plurality of mounting holes and mounting clearance holes.
[0013] In one of the optional technical solutions, the front side of the button mounting position is provided with a first clearance hole matching the button position, a second clearance hole matching the light-emitting element, and a mounting through hole, and the button circuit board is provided with a reserved through hole matching the mounting through hole.
[0014] In one of the alternative technical solutions, the soft rubber part of the receiving component is embedded in and fills the first clearance hole, and the light guide part is embedded in and fills the second clearance hole.
[0015] In one of the alternative technical solutions, the middle part of the soft rubber portion is an elastic gasket, and the outer periphery of the soft rubber portion is a sealing ring.
[0016] In one of the alternative technical solutions, the side of the key body is provided with a protrusion, the middle of the elastic gasket is provided with a groove that matches the protrusion, and the outer periphery of the sealing ring has a sealing structure with alternating concave and convex shapes.
[0017] The above technical solution has the following beneficial effects:
[0018] This utility model provides a beauty device with an improved button structure. It employs a double-layer design combining a dark-colored light-blocking component and a light-colored light-blocking component. The dark-colored component is placed on the inner side to absorb stray light, while the light-colored component covers the outer side to prevent color penetration. This structure completely conceals the dark-colored component internally, allowing only the uniform light transmission of the light-colored component to be visible from the outside, ensuring a clean and color-free appearance for the light-colored beauty device. Simultaneously, the double-layered light-blocking component enhances light-blocking performance, preventing light leakage or spillage, and ensuring that the button markings maintain high contrast and clear display under the light-colored casing, thus balancing aesthetic design and functionality.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] like Figure 1-3 As shown, an embodiment of the present invention provides a beauty device with an improved button structure, including a beauty device body 1 and a button module 2. The beauty device body 1 has an inner shell 11 inside, and a button mounting position 12 is provided on the front side of the inner shell 11. The button module 2 is installed in the button mounting position 12.
[0033] The button module 2 includes a button circuit board 21 connected to the inside of the button mounting position 12, a light-emitting element 22 disposed on the button circuit board 21 and electrically connected to the button circuit board 21, a receiving element 23 installed on the outside of the button mounting position 12, and a key body 24 connected to the receiving element 23. The button circuit board 21 is provided with a plurality of key positions 25.
[0034] The receiving component 23 includes a soft rubber part 231 connected to the key 25 and a light guide part 232 covering the light-emitting component 22. Between the key body 24 and the light guide part 232 of the receiving component 23, there are dark light-shielding components 3 and light light-shielding components 4 stacked sequentially from the inside to the outside.
[0035] The combination of dark-colored light-shielding component 3 and light-colored light-shielding component 4 effectively controls the scattering of the internal light-emitting component 22, allowing the pre-designed patterns or text to be clearly displayed on the button. At the same time, the light from the light-emitting component 22 is evenly diffused by the light guide 232, ensuring that the button markings are clearly visible in low-light environments. The multi-layered light-shielding structure effectively prevents light leakage and improves the clarity of the display. It also allows the dark-colored light-shielding component 3 to be completely hidden inside the button module 2, while only the uniform light transmission effect of the light-colored light-shielding component 4 is visible from the outside. This allows the buttons of the beauty device to adopt a light-colored design, adapting to various colors of the beauty device body 1, avoiding color variations on the button's appearance, and ensuring that the button module 2 provided by this utility model can adapt to various colors of beauty device designs.
[0036] In one embodiment, the dark light-blocking member 3 and the light light-blocking member 4 are respectively provided with light-transmitting patterns of the same shape, and the area of the light-transmitting pattern on the light light-blocking member 4 is larger than the area of the light-transmitting pattern on the dark light-blocking member 3.
[0037] In this embodiment, the light-transmitting pattern of the light-colored light-shielding component 4 is larger than that of the dark-colored light-shielding component 3. This ensures that the dark-colored light-shielding component 3 controls the blocking and scattering of light with a better light-shielding effect, allowing the light-shielding component to precisely control the pattern of light emission. After being controlled by the dark-colored light-shielding component 3, the light can completely pass through the light-transmitting pattern of the light-colored light-shielding component 4, so that the final light emission effect is not affected by the setting of two layers of light-shielding components.
[0038] In one embodiment, both the dark-colored light-shielding component 3 and the light-colored light-shielding component 4 have a primer layer and a paint layer stacked sequentially from the inside out, and the light-transmitting pattern is laser-engraved on the paint layer. Preferably, the paint layer on the dark-colored light-shielding component 3 is black, and the paint layer on the light-colored light-shielding component 4 is white. Furthermore, the outer peripheries of the dark-colored light-shielding component 3 and the light-colored light-shielding component 4 are fixedly bonded.
[0039] In this embodiment, the laser engraving process precisely etches the translucent pattern, ensuring that the edges of the pattern are sharp and burr-free. The primer layer enhances the adhesion of the paint, preventing the coating from peeling off after long-term use. At the same time, the paint layer provides uniform color coverage, further improving the light-blocking performance.
[0040] The black paint layer maximizes light absorption, while the white paint layer reflects excess light. Together, they reduce light loss and enhance the brightness of the translucent pattern. This allows it to be compatible with various colors of beauty device casings, and the paint color can also be selected according to specific needs.
[0041] The perimeter bonding design ensures that the two layers of light-shielding components fit tightly together, preventing separation between the layers due to vibration or temperature differences. It also prevents dust from entering the interlayer and affecting the light transmission effect, ensuring the alignment of the light transmission pattern and the clarity of the illuminated pattern on the button under long-term use.
[0042] In one embodiment, the dark-colored light-shielding member 3 and the light-colored light-shielding member 4 are respectively provided with a plurality of mounting holes and mounting clearance holes.
[0043] In this embodiment, the corresponding design of the mounting hole and the avoidance hole facilitates the accurate positioning of the light shield in the button module 2, simplifies the assembly process, and at the same time prevents the key body 24 from touching the light shield during the installation process, causing the light shield to be misaligned, deformed or damaged.
[0044] In one embodiment, such as Figure 4 As shown, the front side of the button mounting position 12 is provided with a first clearance hole matching the button position 25, a second clearance hole matching the light-emitting element 22, and a mounting through hole. The button circuit board 21 is provided with a reserved through hole matching the mounting through hole. Furthermore, the soft rubber part 231 of the receiving part 23 is embedded and fills the first clearance hole, and the light guide part 232 is embedded and fills the second clearance hole.
[0045] In this embodiment, the first clearance hole and the second clearance hole respectively accommodate the pressing part of the key body 24 and the light guide part 232. The mounting through hole fixes the key circuit board 21 with screws, realizing the quick assembly of the key module 2 and the inner shell 11. The reserved through hole ensures that the key circuit board 21 is not damaged by stress when the screw is installed.
[0046] The interference fit between the soft rubber part 231 and the light guide part 232 and the clearance hole provides a sealing effect to prevent liquid or dust from entering the inner housing 11. At the same time, the elasticity of the soft rubber part 231 enhances the key feel, and the light guide part 232 ensures that light is efficiently transmitted to the surface of the key body 24.
[0047] In one embodiment, the middle part of the soft rubber portion 231 is an elastic gasket, and the outer periphery of the soft rubber portion 231 is a sealing ring. Further, the side of the key body 24 is provided with a protrusion, the middle part of the elastic gasket is provided with a groove that matches the protrusion, and the outer periphery of the sealing ring has a sealing structure with alternating concave and convex sections.
[0048] In this embodiment, the elastic pad provides gentle pressing feedback, and the sealing ring fits tightly against the inner wall of the button mounting position 12 through its concave-convex structure. This double-seal design significantly improves waterproof and dustproof performance, making it suitable for use in humid environments. The structure of the protrusions and grooves effectively restricts the lateral displacement of the button body 24, ensuring that the button body 24 moves only in the vertical direction when pressed, avoiding button jamming or accidental touches caused by misalignment, and improving operational accuracy.
[0049] As needed, the above technical solutions can be combined to achieve the best technical effect.
[0050] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
