[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] See Figures 1-8 This embodiment provides a therapeutic comb, including a housing 1, a first phototherapy component 2, a second phototherapy component 3, and a comb body 4. The housing 1 has a mounting base 12 and a housing body 11 connected to each other, forming an inner cavity 13. The mounting base 12 has a first light-transmitting portion, and the housing body 11 has a second light-transmitting portion. The first phototherapy component 2 is located in the inner cavity 13 and is disposed adjacent to the mounting base 12. The first phototherapy component 2 includes a first circuit board 21 and a first... The first light therapy lamp 22 emits light towards the first light-transmitting part; the second light therapy component 3 is located in the inner cavity 13 and is disposed adjacent to the housing body 11. The second light therapy component 3 includes a second circuit board 31 and a second light therapy lamp 32 that are electrically connected. The light emitted by the second light therapy lamp 32 is directed towards the second light-transmitting part; the comb body 4 is fixed to the mounting base 12. The comb body 4 has a plurality of comb teeth 41 that protrude from the housing 1. The comb body 4 is provided with a third light-transmitting part, and the first light-transmitting part and the third light-transmitting part are disposed correspondingly.

[0043] Thus, the comb body 4 can be used to comb hair. When using the comb body 4 to comb hair, the light emitted by the first light therapy lamp 22 can pass through the first light-transmitting part and the third light-transmitting part to perform light therapy on the scalp; while the light emitted by the second light therapy lamp 32 can pass through the second light-transmitting part on the housing body 11, so that the user can use the housing body 11 to perform light therapy on the skin that does not need to be combed, realizing multiple uses in one device and improving the convenience of use.

[0044] In this embodiment, the mounting base 12 and the housing body 11 can be connected to each other by means of bonding, snap-fit ​​connection, integral molding connection, etc. Preferably, the mounting base 12 and the housing body 11 are connected by snap-fit, which makes it easy to open the inner cavity 13 and maintain the components in the inner cavity 13.

[0045] In this embodiment, the first light therapy lamp 22 can be a white light, red light, blue light, ultraviolet light, or infrared light, etc., and can be set as needed. There can be one or more first light therapy lamps 22. When there are multiple first light therapy lamps 22, they can emit the same light or different light. Similarly, the second light therapy lamp 32 can be a white light, red light, blue light, ultraviolet light, or infrared light, etc., and can be set as needed. There can also be one or more second light therapy lamps 32. When there are multiple second light therapy lamps 32, they can emit the same light or different light; the first light therapy lamp 22 and the second light therapy lamp 32 can emit the same light or different light.

[0046] In this embodiment, the first light-transmitting part can be a through hole connecting the outside and the inner cavity, through which the light emitted by the first light therapy lamp can be emitted outward; or, the first light-transmitting part can be a light-transmitting plate without a through hole, the light-transmitting plate being made of a light-transmitting material, through which the light emitted by the first light therapy lamp can be emitted outward.

[0047] In this embodiment, the second light-transmitting part can be a through hole connecting the outside and the inner cavity, through which the light emitted by the second light therapy lamp can be emitted outward; or, the second light-transmitting part can be a light-transmitting plate without a through hole, the light-transmitting plate being made of a light-transmitting material, through which the light emitted by the second light therapy lamp can be emitted outward.

[0048] In this embodiment, the third light-transmitting part can be a through hole connecting the outside and the inner cavity, through which the light emitted by the first light therapy lamp can be emitted outward; or, the third light-transmitting part can be a light-transmitting plate without a through hole, the light-transmitting plate being made of a light-transmitting material, through which the light emitted by the first light therapy lamp can be emitted outward.

[0049] See Figures 1-3 In some embodiments, the housing body 11 has a handle portion 111, and the comb body 4, the handle portion 111, and the second light-transmitting portion are arranged in sequence.

[0050] Thus, the comb body 4 and the second light-transmitting part are located at both ends of the handle 111. When holding the handle, one can choose to use the comb body 4 to comb the hair and use the first light therapy component 2 to perform light therapy on the scalp, or one can choose to use the second light therapy component 3 to perform light therapy on other parts of the skin through the housing body 11, which facilitates operation and control of the therapeutic comb.

[0051] See Figures 5-7In some embodiments, the outer wall surface of the housing body 11 is provided with a groove 112, and the second light-transmitting part includes a first light-transmitting hole 113. The first light-transmitting hole 113 is disposed on the groove wall of the groove 112 and communicates with the inner cavity 13. The physiotherapy comb also includes a connector 5. The connector 5 is installed in the groove 112 and seals the first light-transmitting hole 113. The connector 5 is provided with a fourth light-transmitting part, which is correspondingly disposed with the first light-transmitting hole 113.

[0052] Thus, the light emitted by the second light therapy lamp 32 can pass through the first light-transmitting hole 113 and the fourth light-transmitting part in sequence and shine outward to the human skin to perform phototherapy on the skin; the first light-transmitting hole 113 is sealed by the connector 5, so that external liquids, dust and other substances cannot easily enter the interior of the therapy comb through the first light-transmitting hole 113.

[0053] In this embodiment, the connector 5 can be connected to the groove wall of the groove 112 by means of snap-fit ​​connection, glue bonding, injection molding, etc., and no limitation is made here.

[0054] See Figures 5-8 In some embodiments, the physiotherapy comb further includes a physiotherapy component 6, which is disposed on the side of the connector 5 away from the first light-transmitting hole 113. The physiotherapy component 6 is provided with a second light-transmitting hole 61 corresponding to the first light-transmitting hole 113. The fourth light-transmitting part includes a base 51 and a light-transmitting protrusion 52 that are fixedly connected. The base 51 seals the first light-transmitting hole 113. The light-transmitting protrusion 52 is disposed on the side of the base 51 away from the first light-transmitting hole 113. At least part of the light-transmitting protrusion 52 extends into the second light-transmitting hole 61 and seals the second light-transmitting hole 61.

[0055] Thus, when the therapeutic component 6 is close to or in contact with the skin, it can provide physical therapy to the skin; the light emitted by the second light therapy lamp 32 can be projected outward to the human skin through the first light-transmitting hole 113, the substrate 51, the light-transmitting protrusion 52 and the second light-transmitting hole 61 to provide phototherapy to the skin; the second light-transmitting hole 61 is sealed by the light-transmitting protrusion 52, so that external liquids, dust and other substances are not easy to enter the interior of the therapeutic comb through the second light-transmitting hole 61.

[0056] In this embodiment, the light-transmitting protrusion 52 can be fixedly connected to the substrate 51 by means of snap-fit ​​connection, adhesive bonding, injection molding, etc., and no limitation is made here.

[0057] See Figure 8 In some embodiments, the therapeutic component 6 has a skin-contact surface for contact with the skin. Thus, when the skin-contact surface is close to or in contact with the skin, it can provide physical therapy to the skin, including but not limited to phototherapy, electrotherapy, cold compress, hot compress, vibration, or massage.

[0058] In this embodiment, the physiotherapy component 6 can be made of materials such as stainless steel, gold plating, rhodium plating, silicone, and ceramic. Preferably, the physiotherapy component 6 is made of stainless steel, which is more robust and durable, more corrosion resistant, and easier to clean and disinfect.

[0059] See Figure 6 and Figure 7 In some embodiments, the light-transmitting protrusion 52 protrudes from the skin-contacting surface. In this embodiment, the therapeutic component 6 has a second light-transmitting hole 61. The edge of the second light-transmitting hole 61 is prone to burrs, which can easily cause scratches on the skin-contacting surface when in contact with the skin. By designing the light-transmitting protrusion 52 to protrude from the skin-contacting surface, the edge of the second light-transmitting hole 61 is less likely to directly contact the skin, which helps to reduce the risk of skin scratches. At the same time, the light-transmitting protrusion 52 protrudes from the skin-contacting surface, forming a raised dot structure, which can be used to massage the skin.

[0060] See Figure 2 , Figure 5 and Figure 8 In some embodiments, the skin-contact surface is provided with massage textures 62. When the skin-contact surface rolls on the skin, the uneven structure formed by the massage textures 62 compresses and releases the subcutaneous tissue and blood vessels, which can promote local blood circulation and accelerate skin metabolism. The massage textures 62 can be raised structures or grooved structures, and are not limited thereto.

[0061] See Figure 2 , Figure 5 and Figure 8 In some implementations, the skin-contacting surface is curved, which makes it less likely to damage the skin when in contact with it, and the curved design better fits the curves of the human body, making it easier for the skin-contacting surface to approach or contact the skin for physiotherapy.

[0062] In this embodiment, the skin-contacting surface can be a flat, round, U-shaped, or hemispherical arc surface. Preferably, the skin-contacting surface is a hemispherical surface, which has greater versatility. No matter which part of the body it contacts, the hemispherical surface can achieve good contact with the skin through a point or a small contact surface, ensuring effective energy transfer.

[0063] See Figure 2 , Figure 5 and Figure 8 In some embodiments, the therapeutic comb further includes a first electrode element 7 and a second electrode element 8, which are disposed on the housing 1 and exposed on the skin-contacting surface. By simultaneously contacting the first electrode element 7 and the second electrode element 8 with the skin to form an electrical circuit, the microcurrent in the electrical circuit can pass through the skin, thereby achieving microcurrent treatment of the skin; the exposure of the first electrode element 7 and the second electrode element 8 on the skin-contacting surface facilitates contact between the first electrode element 7 and the second electrode element 8 and the skin.

[0064] In this embodiment, the first electrode element 7 and the second electrode element 8 can be electrode blocks, electrode needles, electrode rings, or other electrode elements. Preferably, the first electrode element 7 and the second electrode element 8 are electrode rings, and the two electrode rings are arranged on the skin-contact surface, so that the user does not need to distinguish the direction of use, thus improving the convenience of use.

[0065] See Figure 5 and Figure 6 In some embodiments, the physiotherapy component 6 and the connector 5 are detachably connected. In this embodiment, the physiotherapy component 6 and the connector 5 can be detachably connected by means of threaded connection, snap-fit ​​connection, magnetic connection, etc., which facilitates the removal of the physiotherapy component 6 for cleaning.

[0066] See Figures 4-6 In some embodiments, the therapeutic comb also includes an electrical control component 9, which is disposed in the inner cavity 13. The first phototherapy component 2 and the second phototherapy component 3 are both electrically connected to the electrical control component 9. The electrical control component 9 can provide power to the first phototherapy component 2 and the second phototherapy component 3 and can control the first phototherapy component 2 and the second phototherapy component 3 to turn on or off. The first phototherapy component 2 and the second phototherapy component 3 are respectively located on opposite sides of the electrical control component 9, which facilitates the electrical connection between the first phototherapy component 2, the second phototherapy component 3 and the electrical control component 9 and reduces the difficulty of wiring.

[0067] Specifically, the electronic control component 9 includes a battery and a third circuit board (not shown in the figure) disposed in the inner cavity 13. The first circuit board 21, the second circuit board 31, the first electrode element 7, the second electrode element 8 and the battery are all electrically connected to the third circuit board, and the battery can supply power to the third circuit board.

[0068] See Figures 1-8 In some embodiments, the comb body 4 is made of a light-transmitting material. In this way, the light emitted by the first light therapy lamp 22 can pass through the first light-transmitting part and the comb body 4 and be projected outward to the human skin to perform phototherapy on the skin.

[0069] In this embodiment, the comb body 4 can be made of light-transmitting materials such as transparent silicone, polycarbonate, and polymethyl methacrylate, and there is no limitation on this.

[0070] See Figure 1 , Figure 4 and Figure 6In some embodiments, the mounting base 12 has a protrusion 121 extending away from the second phototherapy component 3, and the comb body 4 has a clearance hole 42. The protrusion 121 extends out of the housing 1 through the clearance hole 42 to contact the skin. The physiotherapy comb also includes a temperature control device 122, which is disposed in the inner cavity 13 and is thermally connected to the protrusion 121 to heat or cool the protrusion 121. When the protrusion 121 contacts the skin, it can apply cold or hot compresses to the skin, enriching the physiotherapy functions of the physiotherapy comb and realizing multiple uses in one device.

[0071] See Figure 6 In some embodiments, the protrusion 121 has a cavity 1211 communicating with the inner cavity 13, and the temperature control 122 is attached to the cavity wall of the cavity 1211.

[0072] In this way, the heat or cold air generated by the temperature control 122 can be directly transferred to the cavity wall of the cavity 1211, and then quickly diffuse to the outer wall of the entire protrusion 121, which greatly shortens the path of heat transfer to the working surface, so that the outer wall of the protrusion 121 can quickly reach the preset temperature, resulting in a better user experience. Since the cavity 1211 of the protrusion 121 is connected to the inner cavity 13, it is convenient for the temperature control 122 to be electrically connected to the electronic control component 9 in the inner cavity 13 to provide power to the temperature control 122.

[0073] Among them, the temperature control element 122 can be a heating element, heating tube, heating coil, compression refrigeration component, semiconductor refrigeration component, etc., and can be set according to requirements.

[0074] See Figure 4 and Figure 6 In some embodiments, the outer wall of the protrusion 121 has an arc-shaped structure. Because the protrusion 121 has an arc-shaped structure, it can glide smoothly when in contact with skin or hair, reducing the risk of scratching the skin or pulling the hair.

[0075] See Figure 6 In some embodiments, the height of the comb teeth 41 exposed above the housing 1 is greater than the height of the protrusion 121 exposed above the housing 1. Because the height of the comb teeth 41 is higher than the height of the protrusion 121, the protrusion 121 does not affect the use of the comb teeth 41. When combing hair, the comb teeth 41 can be close to the scalp to massage the scalp and promote blood circulation.
