Therefore, they should not be construed as limitations on this utility model.

[0037] like Figures 1-7As shown, in the first aspect, this application provides an accessory 100 for a nursing device 200, which is assembled onto the nursing device 200. The accessory 100 has a conductive and flexible housing 1 and a flexible light guide 2 enclosed inside the housing 1. A connection end 11 is formed at the first end of the housing 1. The nursing device 200 has an emission port 61 that can emit light. The connection end 11 is configured to connect to the emission port 61. The housing 1 and the internal control circuit of the nursing device 200 are electrically connected at the connection end 11. The light guide 2 can conduct light along the axial direction of the housing 1. A light-transmitting component 3 is provided at the second end of the housing 1. The light-transmitting component 3 is used to close the housing 1 and conduct light out of the housing 1.

[0038] Based on the above technical solution, the accessory 100 of this application can be assembled into the light-emitting port 61 of the nursing device 200. The housing 1 of the accessory 100 and the internal control circuit of the nursing device 200 are electrically connected at the light-emitting port 61. The nursing device 200 has multiple light-emitting ports 61, and each light-emitting port 61 is connected to the accessory 100. The positive and negative output terminals of the internal control circuit of the nursing device 200 can be electrically connected to different accessories 100. After being energized, these accessories 100 can serve as positive and negative electrodes for electrostimulation therapy to deliver electric shocks to the human body, such as stimulating hair follicles inside the scalp, accelerating blood circulation, and promoting hair growth. At the same time, the light-emitting port 61 of the nursing device 200 can emit light, and the light guide component 2 inside the accessory 100 can guide the light along the accessory housing. The light is conducted axially from body 1 and exits from the light-transmitting component 3 to provide light therapy to the human body, such as stimulating cell regeneration in the scalp and promoting hair growth. Furthermore, a closed electric shock current circuit is formed between the internal control circuit of the care device 200, the accessory 100 which serves as the positive and negative poles for electric stimulation therapy, and the human body. That is, the second end of the accessory housing 1 will provide an electric shock to the skin of the human body, such as the scalp. At the same time, the accessory 100 can conduct the light emitted from the emission port 61 of the care device 200 to the location on the human skin that receives the electric shock. The light can relieve the fatigue of the human skin, repair damage, and amplify the effect of the electric shock on the human skin, thus expanding the effects of promoting cell regeneration, repairing damaged hair follicles, and accelerating blood circulation. The effective treatment area for hair care is wide and the care effect is obvious.

[0039] This application also provides a nursing device 200 in a second aspect, including multiple accessories 100 as in the first aspect and a main body 4; the main body 4 is provided with multiple light-emitting holes 41 communicating with the interior and exterior of the main body 4, and the light-emitting side 411 of the light-emitting hole 41 is connected to the connection end 11 of the accessory 100; the main body 4 is provided with an electric shock control circuit 51 and a light source assembly 6; the electric shock control circuit 51 is disposed inside the main body 4, and the output end of the electric shock control circuit 51 is electrically connected to the housing 1 of the accessory 100, and the electric shock control circuit 51, the housing 1 and the human body form a current loop; the light source assembly 6 has multiple emission ports 61, all located inside the main body 4, which can emit parallel light rays 65, and the emission ports 61 are connected to the light-inlet side 412 of the light-emitting hole 41, and the light guide component 2 can conduct the parallel light rays 65 out parallel from the second end of the housing 1.

[0040] The nursing device 200 of this application includes multiple accessories 100 and a main body 4. The main body 4 is equipped with an electric shock control circuit 51 and a light source assembly 6. The electric shock control circuit 51 is located inside the main body 4. The nursing device 200 has an emission port 61 that can emit parallel light rays 65. The housing 1 of the accessory 100 is connected to the light-emitting side 411 of the light-emitting hole 41, and the housing 1 and the internal control circuit of the nursing device 200, namely the electric shock control circuit 51, are electrically connected at the connection end 11. The electric shock control circuit 51, the housing 1, and the human body form a closed electric shock current loop, which can... For use in hair care; the light source assembly 6 has multiple emission ports 61 located inside the main body 4 that can emit parallel light rays 65. Each emission port 61 corresponds to and is connected to the light-inlet side 412 of the light-emitting hole 41. The light guide component 2 can conduct the parallel light rays 65 emitted from the emission ports 61 out parallel from the second end of the housing 1, and make the parallel light rays 65 conduct along the axial direction of the housing 1. The second end of the housing 1 is provided with a light-transmitting component 3, which is used to close the housing 1 and conduct the parallel light rays 65 out to the outside of the housing 1. The parallel light rays 65 can be used for hair care.

[0041] Therefore, this hair care device 200 is used in hair care and can provide both photostimulation and electrical stimulation therapy, effectively improving the effect of hair care and meeting people's demands for comfort, convenience and effortlessness.

[0042] It should be noted that human skin has a relatively high resistance, and the initial sensation of electric current is a slight tingling or a weak needle-like sensation. This accessory 100 is used in the care device 200 to part the hair on the head, so that electrical and light stimulation can directly act on the scalp, conducting microcurrents to the human body. The microcurrents penetrate from the epidermis to the dermis, which can accelerate the metabolic function of the scalp, promote hair follicle growth, and promote hair growth.

[0043] Adhering to the principle of providing people with comfortable, convenient, and effortless health care massage, this accessory 100 is assembled on the care device 200. During health care, this accessory 100 should make relatively gentle and soft contact with the skin of the human body, such as the head. The shell 1 of this accessory 100 should be flexible and not too hard, otherwise it will squeeze the skin and bring an unpleasant experience to the user. In addition, the shell 1 of this accessory 100 should be able to return to its original shape after the care so that it can be used for health care massage again. Furthermore, this accessory 100 also needs to be able to conduct electricity and light.

[0044] In this regard, the housing 1 of this accessory 100 is a flexible and conductive integral structure made of conductive material. A light guide component 2 is provided inside the housing 1 to conduct the light emitted from the emission port 61 of the nursing device 200. Alternatively, the housing 1 has a conductive part 12 and an insulating part 13, which are joined together by insert injection molding. The conductive part 12 has a connecting section 121, a deformable section 122 and an electrode section 123. The first end of the insulating part 13 forms a connecting end 11. A portion of the connecting section 121 is exposed on the inner or outer side of the connecting end 11 and can be electrically connected to the internal control circuit. The deformable section 122 is embedded inside the insulating part 13. A portion of the electrode section 123 is exposed on the outer side of the second end of the insulating part 13 and is configured as an electrode.

[0045] The interior of the insulating part 13 has a cavity, and the light guide component 2 is assembled inside the cavity.

[0046] Whether the housing 1 of this accessory 100 is made of conductive material or the conductive part 12 and the insulating part 13 are combined by insert injection molding to form the housing 1 of this accessory 100, the hardness of the housing 1 of this accessory 100 needs to be maintained in the range of 50°-70°. This can maintain a good tactile feel and can restore its shape well, so that it can be used for long-term health care, such as long-term health care massage.

[0047] The shell 1, made of conductive material, has good conductivity and can effectively transmit the current of the nursing device 200. It forms a good closed electric shock current loop with the internal control circuit of the nursing device 200 and the human body, which can be used for long-term electric stimulation therapy to ensure the treatment effect.

[0048] In some embodiments, the conductive material includes conductive rubber. The accessory housing 1 made of conductive rubber has good deformation and conductivity, which can effectively transmit the current of the internal control circuit of the care device 200 to the human skin. It can be bent at will and can return to its original shape when not under stress.

[0049] The housing 1 of this accessory 100 is formed by insert injection molding and also needs to have the same conductivity so that it can form a good closed electric shock current loop with the internal control circuit of the nursing device 200 and the human body.

[0050] In some embodiments, the portion of the connecting segment 121 exposed on the inner or outer side of the connecting end 11 forms a conductive contact surface 121a, and the conductive contact surface 121a forms a surface contact with the output end of the internal control circuit; the electrode segment 123 exposed on the outer side of the second end of the insulating portion 13 forms an electrode contact surface 123a, and the electrode contact surface 123a is configured to form a surface contact with the human body.

[0051] The conductive contact surface 121a and the output terminal of the internal control circuit of the nursing device 200 form a surface contact at the emission port 61. The resistance between the conductive contact surface 121a and the output terminal of the internal control circuit of the nursing device 200 is small, resulting in low current loss and efficient transmission of the current output by the internal control circuit of the nursing device 200. Simultaneously, the electrode contact surface 123a forms a surface contact with the area of ​​the human skin requiring electrostimulation treatment. The contact resistance between the electrode contact surface 123a and the human skin is relatively small, resulting in low current loss of the internal control circuit of the nursing device 200. The nursing device 200 outputs the correct amount of current to the human skin, providing precise electrical stimulation treatment without causing stinging or discomfort to the user.

[0052] It should be noted that the resistance of human skin varies in different locations, and the amount of current applied to the skin during electrical stimulation therapy varies. For example, applying current of tens to hundreds of microamps is required for electrical stimulation therapy of the scalp.

[0053] In some embodiments, the length of the electrode segment 123 exposed outside the second end of the insulating portion 13 is 0.1 mm to 0.3 mm, preferably 0.1 mm.

[0054] This accessory 100 is fitted to the light-emitting port 61 of the care device 200. The light guide component 2 inside the accessory housing 1 can conduct the light emitted from the light-emitting port 61 to the light-transmitting component 3. This light can be transmitted from inside the light-transmitting component 3 to the user's skin for photostimulation therapy, so as to cooperate with the electrical stimulation therapy and make the health care effect of the care device 200 better.

[0055] The light guide component 2 needs to be bent in conjunction with the accessory housing 1, and can return to its original shape after the treatment is completed. At the same time, it must ensure that the light is not lost during transmission inside, and ensure that the light emitted from the emission port 61 of the care device 200 can be transmitted to the human skin without damage. The amount of light emitted from the emission port 61 of the care device 200 is exactly the amount of light that acts on the human skin, so as to accurately perform photostimulation treatment on the human skin.

[0056] In some embodiments, the light guide component 2 includes an optical fiber 21, the inner diameter of which is larger than the inner diameter of the emission port 61 of the care device 200, and the optical fiber 21 and the emission port 61 are coaxially arranged.

[0057] The optical fiber 21 can be bent freely and will recover its original shape well after bending, or it can follow the housing 1 of accessory 100 to recover its shape before treatment. Furthermore, the optical fiber 21 can transmit the light emitted from the emission port 61 of the care device 200 without loss. This ensures that the care device 200 accurately applies photostimulation therapy to the human skin, ensuring the effectiveness of the photostimulation therapy, avoiding discomfort caused by excessive light intensity, and avoiding insignificant effects due to insufficient light intensity. The light emitted from the emission port 61 of the care device 200 is a parallel light ray 65. The optical fiber 21 can conduct the parallel light ray 65, ensuring that the parallel light ray 65 is emitted vertically from the light-transmitting component 3 without tilting, maximizing the energy of the light on the human skin and preventing light leakage.

[0058] Specifically, the way in which the optical fiber 21 is assembled inside the housing 1 of the accessory 100 can refer to the common methods in the prior art, and will not be described in detail here; in other embodiments, this application may also use other components that can transmit light without damage, which will not be listed in detail here.

[0059] In some embodiments, the housing 1 of accessory 100 is manufactured using an insert injection molding process, and the conductive part 12 can be selected from a metal spring 124 or a metal spring sheet. Therefore, the conductive part 12 includes a metal spring 124 and a metal spring sheet, with the metal spring 124 encasing the optical fiber 21. In some embodiments, the nursing device needs to be equipped with multiple accessories 100 of this application, serving as electrodes for outputting electrical energy from the nursing device and as a medium for guiding the light emitted from the emission port of the nursing device. Among these accessories 100, the conductive part 12 of the housing 1 of some accessories 100 can be selected from a metal spring 124, while the conductive part 12 of the housing 1 of some accessories 100 can be selected from a metal spring 124. The conductive portion 12 of the housing 1 of accessory 100 can be made of metal springs. For example, a portion of accessory 100 with metal springs 124 can be used as the positive electrode for electrical stimulation therapy, and a portion of accessory 100 with metal springs can be used as the negative electrode for electrical stimulation therapy. Alternatively, all accessories 100 with metal springs 124 can be used as both the positive and negative electrodes for electrical stimulation therapy, or all accessories 100 with metal springs can be used as both the positive and negative electrodes for electrical stimulation therapy. In addition, other components with the same effect in the prior art can be used to replace the metal springs 124 and metal springs, which will not be described in detail here.

[0060] To simplify the manufacturing process and reduce the difficulty, this application sets the housing 1 of accessory 100 to a cavity structure. In order to ensure that light can be transmitted through the second end of the accessory housing 1 without damage, the second end of the accessory housing 1 needs to be opened and a light-transmitting component 3 is set there.

[0061] Here, an opening 14 is formed at the second end of the housing 1, the light-transmitting component 3 is sealed and connected to the opening 14, one end of the light-guiding component 2 is connected to the connecting end 11, and the other end abuts against the light-transmitting component 3.

[0062] In one embodiment of this application, the light guide component 2 is an optical fiber 21. One end of the optical fiber 21 is connected to the connection end 11, and the other end abuts against the light-transmitting component 3, so that the light-transmitting component 3 can be locked in the opening 14 at the second end of the accessory housing 1. The optical fiber 21 and the light-transmitting component 3 are always tightly connected. In this way, light can be accurately transmitted from the optical fiber 21 to the light-transmitting component 3 without leakage from the assembly gap between the optical fiber 21 and the light-transmitting component 3. Furthermore, the light-transmitting component 3 can transmit light without loss and act on the human skin to accurately perform photostimulation therapy.

[0063] In actual hair care and maintenance, sometimes it is necessary to use hair growth liquid for treatment, or sometimes it is necessary to wet the scalp for treatment. At this time, it is necessary to ensure that the hair growth liquid or water does not enter the interior of the accessory housing 1, so as to avoid contaminating the light guide component 2 inside the accessory housing 1, so as not to affect the effect of photostimulation treatment.

[0064] Therefore, it is necessary to seal the second end of the light-transmitting component 3 and the accessory housing 1.

[0065] Specifically, the light-transmitting component 3 has a first light-transmitting part 31 and a second light-transmitting part 32, and a step 33 is formed between the first light-transmitting part 31 and the second light-transmitting part 32. Correspondingly, the housing 1 has an annular wall part 15 formed at the opening 14. The first light-transmitting part 31 and the annular wall part 15 are sealed together. The side of the second light-transmitting part 32 is connected to the opening 14. The light-emitting surface 34 of the second light-transmitting part 32 is located inside or outside the opening 14.

[0066] Therefore, the light-transmitting component 3 and the accessory housing 1 are sealed together at the opening 14 at their second end, which can prevent hair growth liquid or moisture from entering the interior of the housing 1 and avoid contaminating the light guide component 2.

[0067] In some embodiments, the light-transmitting component 3 includes a planar lens and a collimating lens. The light-transmitting component 3 can transmit light without damage, allowing it to act on the skin of the human body. The light-transmitting component 3 can be a planar lens, and the emission port 61 of the care device 200 can emit parallel light rays 65. The planar lens can shoot the parallel light rays 65 vertically. Alternatively, the light-transmitting component 3 can be a collimating lens, and the emission port 61 of the care device 200 can emit divergent light rays. The collimating lens can collimate the divergent light rays, allowing them to be shot vertically. When the light is shot vertically and irradiates the human skin, the effect of photostimulation therapy can be maximized.

[0068] Specifically, in some embodiments, the conductive portion 12 of this application is selected as a metal spring 124 or a metal spring sheet. The length of the electrode segment 123 of the metal spring 124 or the metal spring sheet exposed outside the light-transmitting component 3 at the second end of the insulating portion 13 is 0.1mm-0.3mm, preferably 0.1mm.

[0069] The accessory 100 of this application is assembled on the nursing device 200 to perform photostimulation therapy and electrical stimulation therapy. For ease of assembly, the connecting end 11 and the emission port 61 of the nursing device 200 are threaded or snapped together.

[0070] This nursing device 200 can emit parallel light rays 65. The parallel light rays 65 enter vertically from the light guide component 2 inside the accessory housing 1 and exit vertically from the light-transmitting component 3 at the second end of the accessory housing 1. When applied vertically to the human skin, the light stimulation therapy effect can be maximized.

[0071] To ensure the emission of parallel light rays at 65°, reduce light loss, and achieve the best photostimulation therapy effect.

[0072] The light source assembly 6 of this application includes a plurality of light sources 62 and a number of collimating components 63 corresponding to the light sources 62. A light source 62, a collimating component 63 and a light-emitting aperture 41 are coaxially arranged.

[0073] The collimating component 63 can collimate the divergent light emitted by the corresponding light source 62, turning it into a parallel light ray 65, thus reducing light loss. Furthermore, the collimating component 63 and the light output aperture 41 are coaxially arranged, which can prevent the light from being blocked by the side wall of the light output aperture 41 and thus causing loss.

[0074] In order to prevent light from being reflected and lost before entering the light guide component 2 inside the accessory housing 1 and coming into contact with the connection end 11 of the accessory housing 1, the light guide component 2 is also coaxially arranged with the light outlet 41, the collimating component 63 and the light source 62 when no external force is applied.

[0075] In some embodiments, the light guide component 2 includes an optical fiber 21, the inner diameter of which is larger than the inner diameter of the light outlet aperture 41, and the optical fiber 21 and the light outlet aperture 41 are coaxially arranged.

[0076] The collimating component 63 of this nursing device 200 includes a collimating lens, which can collimate the diverging light emitted from the light source 62 into parallel light rays 65.

[0077] Specifically, the light source 62 of this application is not limited to lasers, but also includes LED light panels. A collimating lens with a suitable focal length can be selected according to the size of the divergence angle of the light emitted by the light source 62.

[0078] The main body 4 of this nursing device 200 includes an upper cover 7, a lower cover 8, and a circuit board 5. The light source assembly 6 includes a light source board 64. The upper cover 7 has multiple mounting holes 71 that penetrate its opposite sides. The circuit board 5 is located on one side of the upper cover 7 and has a light emission hole 41. The light emission hole 41 corresponds to the mounting hole 71. The connecting end 11 of the accessory housing 1 is connected to the light emission hole 41, and the electric shock control circuit 51 on the housing 1 and the circuit board 5 forms an electrical connection at the light emission hole 41. The lower cover 8 is connected to the upper cover 7. The lower cover 8 and the upper cover 7 together cover the circuit board 5 and the first end of the housing 1 of the accessory 100, i.e., the connecting end 11. The second end of the housing 1 of the accessory 100 is located outside the lower cover 8. The light source board 64 is located on the other side of the upper cover 7. The light source board 64 has a light source 62, which corresponds to the mounting hole 71. The collimating component 63 is arranged inside the mounting hole 71.

[0079] Specifically, the lower cover 8 is provided with an assembly hole 81 corresponding to the light emission hole 41. The side wall of the housing 1 of the accessory 100 and the assembly hole 81 form a sealed connection to prevent hair growth liquid or moisture from entering the interior of the main body 4, causing a short circuit in the internal circuit of the main body 4, or contaminating the collimating component 63 and affecting the light emission. The second end of the housing 1 of the accessory 100 is located outside the assembly hole 81.

[0080] The electric shock control circuit 51 on the internal circuit board 5 of the main body 4 of this nursing device 200 includes a pulse current control circuit and a radio frequency current control circuit. The positive and negative output terminals of the electric shock control circuit 51 are electrically connected to different accessories 100, dividing the accessories 100 into positive accessory 52 and negative accessory 53. The positive accessory 52 and negative accessory 53 form a closed electric shock current loop with the electric shock control circuit 51 and the human body, respectively. The current in the electric shock control circuit 51 can flow through the human skin to perform electric stimulation therapy on the human body.

[0081] In some embodiments, the circuit board 5 is not limited to PCB and FPC, as well as aluminum substrate, copper substrate, etc.

[0082] The product forms of this nursing device 200 include, but are not limited to, combs, hair growth caps, and massagers.

[0083] In a third aspect, this application also proposes a hair growth comb, including a care device 200 as described in the second aspect. The care device 200 has a lower cover 8, and the lower cover 8 is further provided with a plurality of components 9 parallel to the housing 1 of the accessory 100. The accessory 100 and the components 9 serve as the comb teeth 10 of the hair growth comb.

[0084] Specifically, component 9 is surrounded by accessory 100, component 9 includes soft rubber component 9, and component 9 and accessory 100 are the same size.

[0085] In some embodiments, the accessory 100 and component 9 serve as the comb teeth 10 of a hair growth comb. The outer diameter of the comb teeth 10 is 4mm-5mm, the length is 14mm-17mm, and the hardness is 50° to 70°. At this hardness, the comb teeth 10 can be bent arbitrarily without scratching the skin of the human head, and can automatically return to their original shape after bending.

[0086] This hair growth comb can be used for hair care and treatment, while also providing photostimulation and electrostimulation therapy to the scalp. The comb teeth 100 emit light to stimulate cell regeneration on the scalp, promoting hair growth. Furthermore, the comb teeth 100 act as the positive and negative electrodes for electrostimulation, forming a closed electrical current circuit with the scalp. This provides an electric shock to the scalp, relieving fatigue and repairing damage. Simultaneously, the light amplifies the effects of the electric shock, further promoting cell regeneration, repairing damaged hair follicles, and accelerating blood circulation. This results in a wide effective treatment area and significant hair care results.
