[0002] With the accelerated pace of life and frequent mental activities, "hair loss" is happening to younger people, with more and more young and middle-aged people joining the ranks of "Mediterranean" people. The trouble of "sudden baldness" is not only a damage to the appearance, but also a blow to the psychology. Investigating the causes of hair loss, in addition to hair loss caused by congenital defects, the most obvious cause is the loss of collagen and damaged blood circulation in hair follicles with age, which leads to insufficient nutrient supply to the hair.

[0040] The embodiment of the present application further proposes a nursing device 200 in the second aspect, comprising a plurality of accessories 100 and a main body 4 as in the first aspect; the main body 4 is provided with a plurality of light emitting holes 41 connecting the inside and the outside of the main body 4, and the light emitting side 411 of the light emitting hole 41 corresponds to and is connected to the connecting 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 arranged inside the main body 4, and the output end of the electric shock control circuit 51 is electrically connected to the shell 1 of the accessory 100, and the electric shock control circuit 51, the shell 1 and the human body form a current loop; the light source assembly 6 has a plurality of emission ports 61 which are all located inside the main body 4 and can emit parallel light rays 65, and the emission ports 61 are connected one by one to the light input side 412 of the light emitting hole 41, and the light guiding component 2 can conduct the parallel light rays 65 in parallel from the second end of the shell 1.

[0041] The nursing device 200 of the present application includes a plurality of accessories 100 and a main body 4, wherein the main body 4 is provided with an electric shock control circuit 51 and a light source assembly 6, wherein the electric shock control circuit 51 is arranged inside the main body 4, and the nursing device 200 has an emission port 61 capable of emitting parallel light 65, wherein the shell 1 connection end 11 of the accessory 100 is connected to the light emitting side 411 of the light emitting hole 41, and the shell 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, and the electric shock control circuit 51, the shell 1 and the human body form a closed electric shock current loop, which can For hair care; the light source assembly 6 has a plurality of emission ports 61 which are all located inside the main body 4 and can emit parallel light 65, the emission ports 61 are connected one by one with the light inlet side 412 of the light outlet 41, the light guide component 2 can conduct the parallel light 65 emitted from the emission ports 61 in parallel from the second end of the shell 1, and make the parallel light 65 be conducted along the axial direction of the shell 1, the second end of the shell 1 is provided with a light-transmitting component 3, the light-transmitting component 3 is used to close the shell 1, and conduct the parallel light 65 out of the shell 1, and the parallel light 65 can be used for hair care.

[0042] Here, the care device 200 is applied to hair care, and can provide light stimulation therapy and electrical stimulation therapy at the same time, effectively improving the effect of hair care, and meeting people's demands for comfort, convenience, and labor saving.

[0043] It should be noted that: human skin has a large resistance, and people initially feel slight numbness and weak tingling of electric current. This accessory 100 is used in the care device 200 to part the hair on the head, so that electrical stimulation and light stimulation can directly act on the skin of the head and transmit the microcurrent to the human body. The microcurrent penetrates from the epidermis to the dermis, which can accelerate the metabolic function of the skin on the head, promote the growth of hair follicles, and promote the growth of hair.

[0044] Adhering to the principle of providing people with comfortable, convenient and labor-saving health care massage, the accessory 100 is assembled on the care device 200. When performing health care, the accessory 100 and the skin of the human body such as the head should produce a relatively soft and gentle contact. The shell 1 of the accessory 100 should be flexible and not too hard, otherwise it will squeeze the skin and bring a bad experience to the user. Moreover, the shell 1 of the accessory 100 can restore its original shape after care so that health care massage can be performed again later. In addition, the accessory 100 also needs to be able to conduct electricity and light.

[0045] In this regard, the shell 1 of the accessory 100 is a flexible conductive integrated structure made of conductive material, and a light-guiding component 2 is arranged inside the shell 1 to conduct the light emitted from the emission port 61 of the nursing device 200; or, the shell 1 has a conductive part 12 and an insulating part 13, and the conductive part 12 and the insulating part 13 are combined together by insert injection molding. The conductive part 12 has a connecting section 121, a deformation section 122 and an electrode section 123. The first end of the insulating part 13 is formed with a connecting end 11, and a part of the connecting section 121 is exposed on the inner side or the outer side of the connecting end 11 and can be electrically connected to the internal control circuit, the deformation section 122 is embedded in the insulating part 13, and a part of the electrode section 123 is exposed on the outside of the second end of the insulating part 13 and is configured as an electrode.

[0046] A cavity is formed inside the insulating portion 13, and the light guide member 2 is mounted inside the cavity.

[0047] Whether the shell 1 of the 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 shell 1 of the accessory 100, the hardness of the shell 1 of the accessory 100 needs to be maintained in the range of 50°-70°, which can maintain a good touch and can restore the shape well, and can be used for long-term health care, such as long-term health care massage.

[0048] The shell 1 formed of conductive material has good conductivity, can well transmit the current of the nursing device 200, and form a good closed electric shock current loop between the internal control circuit of the nursing device 200 and the human body, so that long-term electrical stimulation treatment can be carried out to ensure the treatment effect.

[0049] In some embodiments, the conductive material includes conductive rubber. The accessory shell 1 made of conductive rubber has good deformation ability and conductivity, can transmit the current of the internal control circuit of the care device 200 to the human skin well, and can be bent arbitrarily. After bending, it can restore its original shape without being subjected to force.

[0050] The shell 1 of the accessory 100 is formed by insert injection molding, and also needs to have the same conductivity, so as to form a good closed electric shock current loop between the internal control circuit of the nursing device 200 and the human body.

[0051] To this end, 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 outside 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.

[0052] The conductive contact surface 121a and the output end of the internal control circuit of the nursing device 200 form a surface contact at the position of the transmitting port 61. The resistance between the conductive contact surface 121a and the output end of the internal control circuit of the nursing device 200 is small, and the current loss is small, so the current output by the internal control circuit of the nursing device 200 can be transmitted well. At the same time, the electrode contact surface 123a and the position of the human skin that requires electric shock treatment form a surface contact. The contact resistance between the electrode contact surface 123a and the human skin is relatively small, and the output current loss of the internal control circuit of the nursing device 200 is small. The nursing device 200 outputs an accurate amount of current to the human skin, and performs electrical stimulation treatment with an accurate current on the human skin, which will not cause stinging to the skin and will not cause discomfort to the user.

[0053] It should be noted here that the resistance values ​​of different parts of human skin are different. When performing electrical stimulation therapy, the current passed through the human skin is different. For electrical stimulation therapy of the skin on the human head, a current of tens to hundreds of microamperes is required.

[0054] In some embodiments, the length of the electrode segment 123 exposed outside the second end of the insulating portion 13 is 0.1 mm-0.3 mm, preferably 0.1 mm.

[0055] The accessory 100 is mounted on the emission port 61 of the care device 200 that can emit light. The light-guiding component 2 inside the accessory housing 1 can transmit the light emitted from the emission port 61 to the light-transmitting component 3. The light can be transmitted from the inside of the light-transmitting component 3 to the user's skin for light stimulation therapy, so as to cooperate with the electrical stimulation therapy, thereby making the health care effect of the care device 200 better.

[0056] The light-guiding component 2 needs to be bent in coordination with the accessory housing 1, and can restore its original shape after the treatment is completed. At the same time, it is also necessary to ensure that there is no loss of light during transmission inside it, and to ensure that the light emitted from the emission port 61 of the care device 200 can be transmitted to the human skin without loss. The amount of light emitted from the emission port 61 of the care device 200 is the same as the amount of light that acts on the human skin, thereby accurately performing photostimulation therapy on the human skin.

[0057] In some embodiments, the light guiding component 2 includes an optical fiber 21 , the inner diameter of the optical fiber 21 is larger than the inner diameter of the emission port 61 of the nursing device 200 , and the optical fiber 21 and the emission port 61 are coaxially arranged.

[0058] The optical fiber 21 can be bent at will, and can restore its original shape well after bending, or it can follow the shell 1 of the accessory 100 to restore the shape before nursing treatment; and the optical fiber 21 can transmit the light emitted from the emission port 61 of the nursing device 200 without loss, which can ensure that the nursing device 200 accurately performs light stimulation treatment on the human skin, ensure the effect of light stimulation treatment, avoid excessive light intensity causing discomfort to the user, and avoid too low light intensity causing the light stimulation treatment effect to be unclear. The light emitted from the emission port 61 of the nursing device 200 is parallel light 65, and the optical fiber 21 can conduct the parallel light 65 so that the parallel light 65 is emitted vertically from the light-transmitting component 3 without tilting, so that the energy of the light can be maximized to act on the human skin without light leakage.

[0059] Specifically, the way in which the optical fiber 21 is assembled inside the shell 1 of the accessory 100 can refer to the common way in the prior art, which will not be described in detail here; in other embodiments, the present application can also use other components that can transmit light without loss, which will not be listed in detail here.

[0060] In some embodiments, the shell 1 of the accessory 100 is made by insert injection molding technology, and the conductive part 12 can be made of metal springs 124 or metal shrapnel. Therefore, the conductive part 12 includes a metal spring 124 and a metal shrapnel, and the metal spring 124 wraps the optical fiber 21; in some embodiments, the nursing device needs to be equipped with multiple accessories 100 of the present application, which serve as electrodes for outputting electrical energy of the nursing device and as a medium for exporting light emitted from the transmitting port of the nursing device. Among these accessories 100, the conductive part 12 of the shell 1 of some accessories 100 can be made of metal springs 124, and some The conductive part 12 of the shell 1 of the accessory 100 can be made of metal springs, such as selecting a part of the accessory 100 with a metal spring 124 as the positive electrode of the electrical stimulation therapy, selecting a part of the accessory 100 with a metal spring as the negative electrode of the electrical stimulation therapy, or all accessories 100 with a metal spring 124 are selected as the positive and negative electrodes of the electrical stimulation therapy, or all accessories 100 with metal springs are selected as the positive and negative electrodes of the electrical stimulation therapy; in addition, other components with the same effect in the prior art can also be selected to replace the metal spring 124 and the metal spring, which will not be described in detail here.

[0061] In order to simplify the manufacturing process and difficulty, the present application sets the shell 1 of the accessory 100 to have a cavity structure, and to ensure that light is transmitted undamaged from the second end of the accessory shell 1, it is necessary to penetrate the second end of the accessory shell 1 and set a light-transmitting component 3 here.

[0062] 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 .

[0063] In one embodiment of the present application, the light-guiding component 2 uses an optical fiber 21, one end of the optical fiber 21 is connected to the connecting end 11, and the other end abuts against the light-transmitting component 3, so that the light-transmitting component 3 can be clamped at the opening 14 of the second end of the accessory housing 1, and the optical fiber 21 and the light-transmitting component 3 are always tightly connected, so that light can be accurately transmitted from the optical fiber 21 to the light-transmitting component 3 without leaking from the assembly gap between the optical fiber 21 and the light-transmitting component 3; and the light-transmitting component 3 can transmit the light without loss and act on the skin of the human body, so as to accurately perform light stimulation therapy.

[0064] In actual hair care, 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 shell 1 to avoid contaminating the light guide component 2 inside the accessory shell 1, so as not to affect the effect of the light stimulation treatment.

[0065] For this purpose, the light-transmitting component 3 and the second end of the accessory housing 1 need to be sealed.
