[0029] The utility model provides a button and indication structure and a therapeutic device.

[0030] Combine Figure 1 and Figure 3As shown, in one embodiment of the present invention, the button and indication structure 1 includes a light-shielding member 20, a light-guiding member 10 and a button 30. The light-shielding member 20 includes a button portion 21 and a light-shielding portion 22 connected to each other. A light-transmitting hole 25 is provided on the surface of the light-shielding portion 22. At least one of the connection structures between the button portion 21 and the light-shielding portion 22 is made of elastic material; the light-guiding member 10 is covered on the light-shielding member 20, and a button hole 11 is provided on the surface of the light-guiding member 10. The button portion 21 is arranged opposite to the button hole 11; the button 30 is connected to the button portion 21 through the button hole 11; and the button 30 can drive the button portion 21 to deform and press the switch of the therapeutic device 100. The light emitted by the indicator light of the therapeutic device 100 passes through the light-transmitting hole 25 and is displayed through the light-guiding member 10.

[0031] The button and indicator structure 1 is widely used in medical devices such as electro-ultrasonic therapy devices 100, radiofrequency therapy devices 100, and laser therapy devices 100. The switches of the therapy device 100 can be gear switches, power switches, mode switches, etc. The button and indicator structure 1 typically includes an on / off button and a gear button. Each button 30 is equipped with a corresponding indicator light to provide intuitive feedback. When the user first presses the on / off button, the corresponding indicator light illuminates to indicate that the device is powered on and in standby mode. The therapy device 100 typically has multiple energy levels, and the user can adjust the desired level by pressing the gear button. Each time the level is changed, a different indicator light or a different brightness level of the same indicator light illuminates to indicate the current level of the therapy device 100. When the treatment is complete, the user presses the on / off button again, and the corresponding indicator light turns off to indicate that the device has shut down. Through the above design, the button and indicator structure 1 not only provides user convenience but also enhances the device's interactivity and user experience. The intuitive light feedback allows the user to monitor the device status in real time to ensure the safety and effectiveness of the treatment process.

[0032] In this embodiment, the light guide 10 is made of epoxy resin or hard polycarbonate, etc., so that it has good light transmittance. The light of the indicator light is displayed through the light guide 10 so that the user can know the above working status.

[0033] The shading member 20 is made of materials such as thermoplastic polyurethane or thermoplastic elastomer, which provides excellent shading effects, allowing precise control of light transmission and preventing unnecessary light leakage. At least one of the button portion 21 or the connection structure between the button portion 21 and the shading member 22 is made of an elastic material. The use of the elastic material ensures that when the button portion 21 is pressed, the button portion 21 or the connection structure can produce elastic deformation, thereby pressing and triggering the switch of the therapeutic device 100 to switch the operating state of the therapeutic device 100. After the pressing is completed, the button portion 21 or the connection structure can also automatically return to its original position due to the elastic force of the elastic material. Therefore, the use of the elastic material allows the shading member 20 to have a shading effect while also integrating a pressure-bearing effect.

[0034] The button portion 21 and the light shielding portion 22 can be integrally formed to enhance assembly convenience and structural stability of the light shielding member 20. The light holes 25 can be designed to be circular, oval, or rectangular. The light holes 25 are evenly distributed in an array across the surface of the light shielding portion 22, enhancing the overall aesthetics while ensuring that light from the indicator light is evenly distributed across the surface of the light shielding portion 22, ensuring that the light-transmitting area corresponding to each light hole 25 is adequately illuminated. Of course, the light holes 25 can also be arranged irregularly.

[0035] The button 30 is made of materials such as silicone or plastic to provide good press feedback and resist wear and aging. The surface of the button 30 is designed with a non-slip texture to enhance the user experience. The diameter of the button hole 11 is slightly larger than the diameter of the button 30 to facilitate installation and removal of the button 30. The button 30 can be connected to the button portion 21 through a threaded structure, a snap-fit structure, a slot, and a combination of slots and grooves.

[0036] The light guide 10 is overlaid on the light shielding member 20, so that the light guide 10 and the light shielding member 20 are closely fitted, thereby guiding the light of the indicator light to be emitted from the limited light guide area, effectively blocking unnecessary light leakage. By arranging the button 30 structure on the light indication structure, the present application can realize more buttons 30 and light display functions within the limited space of the therapeutic device 100, thereby improving space utilization, simplifying the manufacturing process, reducing manufacturing costs, and simplifying the assembly process.

[0037] Combine Figure 2 and Figure 3 As shown, in one embodiment of the present invention, a connection hole is opened on the surface of the shading portion 22, and the button portion 21 is located in the connection hole. The connection structure between the button portion 21 and the hole wall of the connection hole is an elastic arm 23, and the button portion 21 can be deformed through the elastic arm 23.

[0038] In this embodiment, the connection hole on the surface of the light shielding portion 22 is arranged vertically corresponding to the button hole 11 on the surface of the light guide 10. The edge of the hole wall of the connection hole is designed to be chamfered to reduce wear on the button portion 21 and improve the overall aesthetics.

[0039] The elastic arm 23 is made of materials such as silicone, thermoplastic polyurethane or thermoplastic elastomer to ensure that the elastic arm 23 can be deformed when the button part 21 is pressed, so that the button part 21 moves and presses against the switch of the therapeutic device 100, thereby switching the working state of the therapeutic device 100. After releasing the button 30 and releasing the pressure, the elastic arm 23 quickly returns to its original state, thereby providing stable button 30 operation feedback. Furthermore, the elastic arm 23 is configured to be arched and protrudes toward the direction of the button 30 to improve the rebound effect after the button 30 is pressed. The elastic arm 23 and the button part 21 are an integrally molded structure to simplify the assembly process and improve the structural stability between the two. In other embodiments, the elastic arm 23 can also be detachably connected to the button part 21.

[0040] Combine Figure 2 and Figure 3 As shown, in one embodiment of the present invention, a plurality of elastic arms 23 are provided, and the plurality of elastic arms 23 are arranged at intervals along the periphery of the button portion 21, and a plurality of light emitting gaps 24 are formed between every two adjacent elastic arms 23. The light of the indicator light is used to be emitted through the light emitting gaps 24 and the light guide 10 on the periphery of the button 30.

[0041] In this embodiment, multiple elastic arms 23 are evenly distributed around the periphery of the button portion 21, effectively dispersing stress points and avoiding stress concentration at a single contact point. This reduces the risk of material fracture and fatigue, thereby forming a stable support structure. Light gaps 24 are distributed along the periphery of the button portion 21, allowing the light from the indicator to form a distinct halo around the button 30. This enhances the visual effect of the button 30, helps the user more easily identify its location and shape when touching it, and improves operational convenience.

[0042] Combine Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a positioning groove 211 is provided on the side of the button portion 21 facing the button 30, and a positioning member 31 corresponding to the positioning groove 211 is provided on the side of the button 30 facing the button portion 21. The positioning member 31 is inserted into the positioning groove 211 so that the button 30 is plugged and connected to the button portion 21.

[0043] In this embodiment, the positioning member 31 is designed as a protrusion with a cross-shaped cross section, and the positioning groove 211 is a cross-shaped groove that matches the positioning member 31, so that the positioning member 31 can be tightly inserted into the positioning groove 211, ensuring the stability of the connection between the key 30 and the key portion 21. The cross-shaped groove provides a guide for the insertion of the positioning member 31, so that the positioning member 31 can be accurately positioned in the positioning groove 211 during insertion. When the positioning member 31 is inserted into the positioning groove 211, the groove wall of the positioning groove 211 limits the positioning member 31 in the circumferential direction, preventing the key 30 from rotating or moving horizontally relative to the key portion 21, so that the key 30 can maintain its position and alignment even after repeated use and under various usage conditions.

[0044] In other embodiments, the positioning member 31 and the positioning groove 211 may also be designed as a structure in which a circular protrusion and a groove, or a polygonal protrusion and a groove cooperate. Alternatively, the positioning member 31 and the positioning groove 211 are not provided, and the button 30 and the button portion 21 are tightly connected via a threaded structure, a snap-fit structure, an elastic clamping structure, or the like.

[0045] Combine Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the light guide 10 is provided with two button holes 11, and two button parts 21 and buttons 30 are provided. Each button 30 is embedded in a button hole 11 and is located in a button part 21; one button 30 is used to control the switch of the therapeutic device 100, and the other button 30 is used to switch the energy gear of the therapeutic device 100.

[0046] In this embodiment, two button holes 11 are spaced apart along the axis of the therapeutic device 100 to facilitate intuitive user identification and operation of the corresponding button 30. The button 30 is designed to match the shape of the button hole 11 and is typically round or square. The button 30 used to control the therapeutic device 100 on and off is an on / off button. A single press of the on / off button switches the state of the therapeutic device 100: a first press activates the device, while a second press deactivates it. This design simplifies user operation and reduces the complexity of learning the device. The button 30 used to switch the energy level of the therapeutic device 100 is a gear button. This button 30 is designed to respond to multiple presses, with each press increasing the energy level of the therapeutic device 100 by one level. The user can select the desired gear level according to their needs. Providing two buttons 30 with different functions improves user convenience. Furthermore, the two buttons 30 can be configured to be different sizes, allowing the user to quickly distinguish between the on / off button and the gear button, thereby reducing misoperation.

[0047] Combine Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the light guide member 10 and the light shielding member 20 are an integrally formed structure;

[0048] And / or, the light guide member 10 is made of hard polycarbonate, and the light shielding member 20 is made of thermoplastic polyurethane or thermoplastic elastomer.

[0049] In this embodiment, the light guide member 10 and the light shielding member 20 are integrally formed by a soft-hard double-color injection molding process. This structure not only simplifies the assembly process, but also improves the durability and waterproof performance of the product.

[0050] When the light guide 10 and the light shading member 20 are limited to be an integrally formed structure or not, the light guide 10 is made of hard polycarbonate material, which has excellent optical transparency to ensure the effective transmission and distribution of light inside the light guide 10. At the same time, its higher hardness also helps to maintain the morphological stability of the light guide 10, thereby ensuring the durability and reliability of the light guide 10 during long-term use.

[0051] The light shield 20 can be made of thermoplastic polyurethane or thermoplastic elastomer. These materials have excellent light-shielding properties and effectively block the passage of light, ensuring that only the light-transmitting aperture 25 and the light-exit gap 24 are transparent, while other areas remain opaque. Furthermore, these materials possess excellent flexibility and elasticity, absorbing and buffering pressure during the operation of the key 30 while maintaining shape stability. This provides the necessary elastic feedback when the key 30 is pressed, enhancing the user experience. After the key 30 is pressed, the light shield 20 returns to its original state due to its elastic recovery force.

[0052] Combine Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the light guide member 10 is provided with a plurality of light guide posts 12 , and a plurality of light transmission holes 25 are provided, and each light guide post 12 is embedded in a light transmission hole 25 .

[0053] In this embodiment, a plurality of light guides 12 are arrayed or evenly spaced on the surface of the light guide 10 to ensure that light is evenly dispersed on the entire surface of the light guide 10, avoiding the situation of local over-brightness or over-darkness, and ensuring the uniformity and consistency of light. Figure 3 As shown, eight light guide columns 12 are provided on the surface of the light guide 10. The eight light guide columns 12 are divided into two groups, each group contains four light guide columns 12, and each group of light guide columns 12 adopts a rotationally symmetrical structure. The light guide columns 12 are evenly spaced within the group to achieve uniform distribution of light and optimize visual effects.

[0054] The shape of the light guide column 12 matches the shape of the light transmission hole 25 and can be circular, elliptical or rectangular. The light guide column 12 is embedded in the light transmission hole 25 to allow light to pass through the light guide column 12 and guide the light to propagate along a specific path.

[0055] The plurality of light guide pillars 12 are disposed between the two button holes 11 , and the central axis of each button hole 11 coincides with the central axes of the two opposite light guide pillars 12 .

[0056] The light guide columns 12 correspond one-to-one to the gears of the therapeutic device 100. Each light guide column 12 represents a specific gear. When the therapeutic device 100 switches to the corresponding gear, the corresponding light guide column 12 will be illuminated so that the user can know the energy gear of the therapeutic device 100.

[0057] Combine Figure 3 As shown, in one embodiment of the present invention, the light shielding member 20 further includes a plurality of light shielding columns 221 . The light shielding columns 221 are protruding from the side of the light shielding portion 22 facing the light guide member 10 and are disposed between every two adjacent light guide columns 12 .

[0058] In this embodiment, the light shielding columns 221 are spaced apart from the light guide columns 12, with at least one light shielding column 221 between every two light guide columns 12. This effectively prevents unnecessary light leakage and crosstalk, while also improving the clarity and contrast of the display through precise light control. When using the therapeutic device 100, the user can clearly see the light emitted by the light guide column 12 corresponding to each gear position, thereby intuitively understanding the current gear position of the therapeutic device 100.

[0059] Combine Figure 2 As shown, in one embodiment of the present invention, a waterproof ring 26 is provided on the side of the light guide 10 away from the light shielding portion 22 , and the waterproof ring 26 is used to seal the light guide 10 and the housing 2 of the therapeutic device 100 .

[0060] In this embodiment, the waterproof ring 26 is made of thermoplastic elastomer or silicone rubber, which makes it have good elasticity and waterproof performance. The cross-section of the waterproof ring 26 can be semicircular, circular or square to adapt to different installation spaces. The waterproof ring 26 is a structure that is raised on the surface of the light guide 10 to form an uninterrupted sealing barrier, which surrounds the joint between the light guide 10 and the housing 2 of the therapeutic device 100 and fits tightly with the housing 2, and has good waterproof and anti-static effects. Through the injection molding process, the waterproof ring 26 is integrally formed with the light shielding member 20 and is tightly combined, effectively preventing the intrusion of moisture and dust, and improving the durability and reliability of the product.

[0061] In other embodiments, the waterproof ring 26 can also be two separate structures from the light-shielding member 20. For example, a sealing gasket or an O-ring can be set on the surface of the light guide member 10, or a sealant can be used on the joint surface between the light guide member 10 and the housing 2 of the therapeutic device 100 to replace the waterproof ring 26, which can also achieve the effect of waterproofing and sealing.

[0062] The present invention also proposes a therapeutic device 100, which includes a shell 2, a light board 3, a button and indicator structure 1. The specific structure of the button and indicator structure 1 refers to the above embodiment. Since the therapeutic device 100 adopts all the technical solutions of all the embodiments of the above-mentioned button and indicator structure 1, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0063] Combine Figure 5 As shown, the light board 3, the button and the indicator structure 1 are all installed on the shell 2. The button and the indicator structure 1 are arranged on the light board 3 and fit tightly with the inner wall of the shell 2. The button 30 is exposed on the surface of the shell 2. When the user presses the button 30 of the therapeutic device 100, it will not only trigger the corresponding functional operation, such as starting, shutting down or switching gears, but also there will be clear light feedback, and the light will be turned on or off to confirm to the user that the operation has been executed.

[0064] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
