[0038] Please combine Figures 1-2 The first embodiment of this utility model provides a liquid-guiding comb 12, which includes a fixed member 120 and a floating member 121 that are movably connected. One end of the fixed member 120 has an opening 1205, and part of the floating member 121 protrudes from the opening 1205. The fixed member 120 has a first cavity 1201 and a second cavity 1202 that are connected to each other. The opening 1205 connects to the second cavity 1202. At least one through hole 1204 connecting to the outside is formed on the inner wall of the second cavity 1202. A stop structure 120 is provided at the connection between the inner walls of the first cavity 1201 and the second cavity 1202. 3. A portion of the floating member 121 is located in the first cavity 1201, and the stop structure 1203 restricts the portion of the floating member 121 located in the first cavity 1201 from entering the second cavity 1202; an elastic member 122 is provided in the first cavity 1201, one end of the elastic member 122 away from the second cavity 1202 is fixedly disposed relative to the fixed member 120, and the other end abuts against the floating member 121, and the portion of the floating member 121 located in the first cavity can abut against or move away from the stop structure 1203 so that the first cavity 1201 and the second cavity 1202 are separated or connected.

[0039] Understandably, the first cavity 1201 and the second cavity 1202 are essential channels for liquid flow. After the liquid enters the second cavity 1202 through the first cavity 1201, it flows to the outside through the through hole 1204. Specifically, the floating member 121 can move relative to the fixed member 120, and part of the floating member 121 is exposed from the opening. When the exposed part of the floating member 121 is subjected to force, it compresses the elastic member 122, and the floating member 121 moves away from the stop structure 1203. At this time, the first cavity 1201 and the second cavity 1202 are connected, allowing the liquid to flow to the through hole. When not in use, due to the force of the elastic member 122, the floating member 121 rebounds and abuts against the stop structure 1203. At this time, the first cavity 1201 and the second cavity 1202 are separated, and the liquid cannot flow into the second cavity 1202, thereby avoiding liquid waste.

[0040] In this embodiment, the elastic element 122 is a spring.

[0041] Understandably, the through hole 1204 is not limited to one, but can be multiple. In this embodiment, multiple through holes 1204 are provided around the second cavity 1202 and spaced apart, so that the hair can be evenly coated from multiple angles.

[0042] Specifically, in this embodiment, the fixing member 120 is a columnar structure with a curved outer surface, which can reduce the resistance when combing hair and make combing hair smoother.

[0043] For further information, please refer to [link / reference]. Figure 2 The floating member 121 includes at least two stacked spheres, one of which engages with the opening 1205 and is partially exposed from the opening 1205, and the other sphere engages with the stop structure 1203 and can abut against or move away from the stop structure 1203.

[0044] Understandably, the spheres abut against each other, and the spheres can not only be pressed against the elastic member 122, but also rotate when subjected to a force not directed toward the elastic member 122. When rotating, the spheres that cooperate with the opening 1205 can bring out the liquid in the second cavity 1202.

[0045] Specifically, in this embodiment, three spheres are used to accommodate the length of the second cavity 1202. Of course, in other embodiments, any number of spheres can be selected according to the actual situation.

[0046] Furthermore, the sphere that mates with the opening is defined as a first sphere 1211, the diameter of the first sphere 1211 being larger than the diameter of the opening and smaller than the inner diameter of the second cavity 1202.

[0047] Understandably, the diameter of the first sphere 1211 ( Figure 2The diameter of the first sphere 1211 is greater than the diameter of the opening, so that only a portion of the first sphere 1211 can protrude from the opening, thus preventing the first sphere 1211 from falling directly out of the opening 1205. Furthermore, the diameter of the first sphere 1211 (r) is greater than the diameter of the opening, thus preventing the first sphere 1211 from falling directly out of the opening 1205. Figure 2 The diameter of r in the second cavity 1202 is smaller than the inner diameter of r. Figure 2 The structure D in the diagram creates a gap between the first sphere 1211 and the second cavity 1202, facilitating the flow of liquid.

[0048] Furthermore, the sphere that mates with the stop structure 1203 is defined as the second sphere 1212, and the diameter of the second sphere 1212 is greater than the minimum inner diameter of the stop structure 1203 and smaller than the inner diameter of the first cavity 1201.

[0049] Understandably, the direct ( Figure 2 The R in the figure is greater than the minimum inner diameter of the stop structure 1203, while in this embodiment, the minimum inner diameter of the stop structure 1203 is equal to the inner diameter of the second cavity. Figure 2 The second sphere 1212 is not fully inserted into the second cavity 1202 when it comes into contact with the stop structure 1203, and the diameter of the second sphere 1212 is smaller than the inner diameter of the first cavity 1201, so that there is a gap between the second sphere 1212 and the first cavity 1201 to facilitate the flow of liquid.

[0050] Understandably, the inner diameters of the first cavity 1201 and the second cavity 1202 are not limited, and they may be the same or different, all of which are within the protection scope of this utility model.

[0051] Specifically, in this embodiment, the stop structure 1203 is an annular step, and the side of the stop structure 1203 that abuts against the sphere matches the outline of the sphere.

[0052] Further, please refer to Figures 3-5 The second embodiment of this utility model also provides a nursing comb 1, including a main body 10 and liquid guiding comb teeth 12 disposed on one side of the main body 10 as described in the first embodiment. The main body 10 includes a liquid storage space 103, and a first cavity 1201 communicates with the liquid storage space 103.

[0053] Specifically, the main body 10 includes a handle 100 and a comb tooth 101, wherein the comb tooth 11 is disposed on one side of the comb tooth 101. Understandably, when using it, the user only needs to hold the handle 100 and apply the corresponding force to control the movement trajectory of the comb tooth 11 on the comb tooth 101, thereby using the comb tooth 11 to comb the hair, massage the scalp, etc.

[0054] The liquid storage space 103 is used to store liquids, such as hair care solutions, medicines, etc., for hair care.

[0055] In use, the liquid in the storage space 103 enters the second cavity 1202 through the first cavity 1201 and flows out from the through hole 1204 opened in the inner wall of the second cavity 1202.

[0056] Furthermore, the main body 10 includes a liquid storage tank 102, the liquid storage space 103 is formed in the liquid storage tank 102, the side of the main body 10 where the comb teeth 11 are set is defined as the working surface 108, the working surface 108 is provided with a groove 104, the liquid storage tank 102 is detachably connected to the groove 104, and the liquid guiding comb teeth 12 are set on the liquid storage tank 102.

[0057] Understandably, the groove 104 matches the shape of the liquid reservoir 102. Since the liquid reservoir 102 is detachably installed in the groove 104, when the contact lens solution needs to be replenished, the liquid reservoir 102 containing the contact lens solution can be quickly removed. After replenishing the contact lens solution, the liquid reservoir 102 can be quickly installed back onto the main body 10, saving time and effort and providing a good user experience.

[0058] Moreover, by directly setting the liquid guide comb 12 on the liquid storage tank 102, the liquid flow path is shortened, reducing liquid waste.

[0059] Furthermore, the comb teeth 11 also include conductive comb teeth 13, which are arranged around the groove 104.

[0060] The main body 10 contains a circuit board 105, and the conductive comb teeth 13 are electrically connected to the circuit board 105. The circuit board 105 conducts microcurrents to the conductive comb teeth 13. After the conductive comb teeth 13 come into contact with the scalp, the microcurrents stimulate the scalp cells. Combined with the comb teeth 11 massaging the scalp, this better stimulates the scalp cells, promotes hair growth, and provides better hair care.

[0061] Specifically, the working surface 108 is provided with a light-transmitting element 106, the conductive comb teeth 13 are disposed on the light-transmitting element 106, and the main body 10 is provided with a light-emitting element 107. The light emitted by the light-emitting element 107 shines out from the working surface 108 through the light-transmitting element 106.

[0062] Understandably, by setting a light-emitting element 107 in the main body 10, light is used to irradiate the scalp, and at the same time, the comb teeth 11 can contact the scalp and massage to awaken the scalp, so that the scalp cells can better receive light stimulation when irradiated, thereby improving the hair growth effect.

[0063] The light can be laser light, etc., and is not limited here.

[0064] Specifically, in this embodiment, the conductive comb teeth 13 are retractable comb teeth 11, which prevents the user's scalp from being poked and causing a poor user experience. Instead, the retractable teeth have a certain massage effect, giving the user a comfortable experience.

[0065] Furthermore, a magnetic suction element 1021 is provided on one of the liquid storage tank 102 and the main body 10, and a mating element 109 is provided on the other to magnetically engage with the magnetic suction element 1021.

[0066] Understandably, the magnetic suction element 1021 and the mating element 109 can both be magnets, or one can be a magnet and the other can be a magnetic metal, or the liquid storage tank 102 can be made of a magnetic metal.

[0067] Because the reservoir 102 is magnetically connected to the main body 10, it can be quickly attached and detached from the main body 10. When it is necessary to replenish the reservoir 102 with contact lens solution, the liquid guide comb 12 on the reservoir 102 can be held to overcome the magnetic attraction between the reservoir 102 and the main body 10 to disassemble the reservoir 102. After replenishing the contact lens solution, the reservoir 102 can be brought close to the main body 10 and reinstalled using the magnetic attraction. Compared with the traditional screw-based assembly and disassembly method, this saves the time of tightening screws, making the reservoir 102 quick, easy, and convenient to use.

[0068] Compared with the prior art, the fluid-guiding comb and care comb provided by this utility model have the following advantages:

[0069] 1. The liquid-guiding comb teeth provided in this embodiment of the utility model include a fixed member and a floating member that are movably connected. The fixed member has a first cavity and a second cavity that are connected. The first cavity is connected to the liquid storage space. The fixed member has an opening and a through hole on its end face and side face that are connected to the second cavity, respectively. A stop structure is provided at the connection between the inner walls of the first cavity and the second cavity. The floating member can abut against or move away from the step so that the first cavity and the second cavity are separated or connected. It can be understood that the liquid-guiding comb teeth are set as a telescopic structure. The liquid is controlled by telescopic movement. It can not only be used to massage the scalp, but also to apply the conditioner to different parts of the hair through the through hole. The liquid guiding part can be applied to the hair root, while the through hole can be applied to the hair other than the hair root, so as to achieve the effect of even application.

[0070] 2. The liquid-guiding comb provided in this embodiment of the utility model has a floating component consisting of at least two stacked spheres that abut against each other. The spheres can not only be pressed by the spring, but also rotate when subjected to a force not directed towards the spring. During rotation, the spheres can bring out the liquid in the second cavity.

[0071] 3. In the liquid-guiding comb provided in this embodiment of the present invention, the diameter of the first sphere is larger than the diameter of the opening, so that only a portion of the first sphere can protrude from the opening, thus preventing the sphere from falling directly out of the opening. Furthermore, the diameter of the first sphere is smaller than the inner diameter of the second cavity, creating a gap between the first sphere and the second cavity to facilitate liquid flow. The diameter of the second sphere is larger than the inner diameter of the second cavity, preventing the second sphere from fully entering the second cavity when it abuts against the stop structure. The diameter of the second sphere is smaller than the inner diameter of the first cavity, creating a gap between the second sphere and the first cavity to facilitate liquid flow.

[0072] 4. The care comb provided in this embodiment of the utility model has a detachable liquid storage tank installed in the groove. When it is necessary to replenish the care solution, the liquid storage tank can be quickly removed. After replenishing the care solution, the liquid storage tank can be quickly installed on the main body, which saves time and effort and provides a good user experience.

[0073] 5. The hair care comb provided in this embodiment of the invention uses a conductive comb tooth to stimulate scalp cells through microcurrent after contacting the scalp. Combined with the comb tooth's massage effect on the scalp, this better stimulates scalp cells, promotes hair growth, and provides better hair care.

[0074] 6. The nursing comb provided in this embodiment of the utility model has a light-emitting element in the main body. The light is used to irradiate the scalp, and the comb teeth can contact the scalp and massage it to wake it up, so that the scalp cells can better receive light stimulation when irradiated, thereby improving the hair growth effect.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
