[0014] Preferably, a magnetic suction element is provided on one of the liquid storage tank and the main body, and a mating element is provided on the other.

[0015] Compared with the prior art, the care comb provided by this utility model has the following advantages:

[0016] 1. The nursing comb provided in this embodiment of the utility model includes a liquid-guiding comb tooth comprising 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 to each other. 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 step is provided at the connection between the inner walls of the first cavity and the second cavity. The floating member includes a limiting end and a liquid-guiding part. The limiting end can abut against or move away from the stop structure to separate or connect the first cavity and the second cavity. It can be understood that the liquid-guiding comb tooth is set as a telescopic structure. The liquid is dispensing is controlled by telescopic movement. It can not only be used to massage the scalp, but also to apply the nursing liquid to different parts of the hair through the through hole to achieve a uniform application effect.

[0017] 2. The hair care comb provided in this embodiment of the present invention has a floating component that is also provided with a liquid distribution channel that connects to the second cavity. When in use, some of the liquid entering the second cavity also enters the liquid distribution channel and then flows out from the liquid outlet. The liquid flowing out from the liquid outlet can more easily contact the scalp. Therefore, the hair care comb provided in this embodiment can better and more evenly care for the hair.

[0018] 3. In the nursing comb provided in this embodiment of the utility model, the diameter of the liquid guiding part gradually decreases from near the limiting end to far away from the limiting end. Since the size of the opening remains unchanged, when the floating part is pressed, the diameter of the liquid guiding part flush with the opening decreases, thereby leaving a gap between the opening and the liquid guiding part. At this time, the liquid in the second cavity can also flow out from the opening, thereby evenly applying the liquid to the hair in multiple directions.

[0019] 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.

[0020] 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.

[0021] 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.

[0038] Please combine Figures 1-4 The first embodiment of this utility model provides a nursing comb 1, including a main body 10 and comb teeth 11 disposed on one side of the main body 10. The main body 10 includes a liquid storage space 103, and the comb teeth 11 include liquid guiding comb teeth 12. The liquid guiding comb teeth 12 include a fixing member 120 and a floating member 121 that are movably connected. The fixing member 120 has a first cavity 1201 close to the main body 10 and a second cavity 1202 away from the main body 10. The first cavity 1201 communicates with the liquid storage space 103. The fixing member 120 has an opening 1205 at the end away from the main body 10. At least part of component 121 is exposed from opening 1205. A through hole 1204 communicating with the outside is provided on the inner wall of the second cavity 1202. A stop structure 1203 is provided at the connection between the inner walls of the first cavity 1201 and the second cavity 1202. An elastic component 122 is provided in the first cavity 1201. The floating component 121 includes a limiting end 1211. The limiting end 1211 is located in the first cavity 1201 and abuts against the elastic component 122. The limiting end 1211 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] 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.

[0040] The liquid storage space 103 is used to store liquids, such as conditioning solutions and medications, for hair care. The limiting end 1211 is located between the stop structure 1203 and the elastic member 122 to prevent the floating member 121 from falling off. Understandably, since the floating member 121 of the liquid-guiding comb teeth 12 is movably connected to the fixed member 120, during use, the floating member 121 is pressed against the elastic member 122, with the limiting end 1211 moving away from the stop structure 1203, thus opening the first cavity 1201. The liquid is connected to the second cavity 1202. At this time, the liquid in the liquid 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. When not in use, due to the force of the elastic member 122, the rebound floating member 121 is made to abut 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.

[0041] In this embodiment, the elastic element 122 is a spring.

[0042] 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.

[0043] Specifically, in this embodiment, both the fixing member 120 and the floating member 121 are columnar structures with curved outer surfaces, which can reduce the resistance when combing hair and make combing hair smoother.

[0044] Please continue reading. Figure 3 and Figure 4 Furthermore, the floating member 121 also includes a liquid guiding part 1212 connected to the limiting end 1211. The liquid guiding part 1212 passes through the first cavity 1201 and is at least partially exposed from the opening 1205. There is a gap between the liquid guiding part 1212 and the inner wall of the second cavity 1202. A liquid distribution channel 1213 is provided in the liquid guiding part 1212. The liquid distribution channel 1213 includes an inlet 1214 communicating with the second cavity 1202 and an outlet 1215 exposed from the opening 1205.

[0045] Understandably, the floating component 121 is also provided with a liquid distribution channel 1213 that connects to the second cavity 1202. During use, some of the liquid entering the second cavity 1202 also enters the liquid distribution channel 1213 and then flows out from the liquid outlet 1215. The liquid flowing out from the liquid outlet 1215 can more easily contact the scalp. Therefore, the hair care comb 1 provided in this embodiment can better and more evenly care for the hair.

[0046] Specifically, in this embodiment, only one liquid outlet 1215 is provided, and it is located at the end of the floating member 121 away from the limiting end 1211; while multiple liquid inlets 1214 can be provided to ensure that enough liquid can enter the liquid distribution channel 1213 as much as possible.

[0047] Please continue reading. Figure 4 Furthermore, at least a portion of the diameter of the liquid guiding portion 1212 gradually decreases from near the limiting end 1211 to away from the limiting end 1211. When the limiting end 1211 abuts against the stop structure 1203, the liquid guiding portion 1212 closes the opening 1205.

[0048] Understandably, in this embodiment, the diameter of a portion of the liquid guiding portion 1212 gradually decreases as it moves further away from the limiting end 1211. The diameter D near the limiting end 1211 is greater than the diameter d far from the limiting end 1211, and gradually decreases from D to d. The cross section with diameter D on the liquid guiding portion 1212 is parallel to the opening 1205 or located in the second cavity, and D is greater than or equal to the diameter of the opening 1205.

[0049] Since the size of the opening 1205 remains unchanged, when the floating part 121 is pressed, the diameter of the liquid guiding part 1212, which is flush with the opening 1205, decreases, thereby leaving a gap between the opening 1205 and the liquid guiding part 1212. At this time, the liquid in the second cavity 1202 can also flow out from the opening 1205, thereby evenly applying the liquid to the hair from multiple directions.

[0050] Furthermore, in this embodiment, when the limiting end 1211 abuts against the step, the liquid guiding part 1212 closes the opening 1205, thereby preventing the liquid remaining in the second cavity 1202 from flowing out.

[0051] Furthermore, the stop structure 1203 is an annular step, and the diameter of the limiting end 1211 is larger than the inner diameter of the stop structure 1203.

[0052] Understandably, the stop structure 1203 is an annular step that surrounds the inner wall of the second cavity 1202, that is, the inner diameter of the first cavity 1201 is smaller than the inner diameter of the second cavity 1202, wherein the minimum inner diameter of the step is equal to the inner diameter of the second cavity 1202.

[0053] Specifically, in other embodiments, there may be multiple diameters of the limiting end 1211 and the inner diameter of the step, that is, the diameters of the limiting end 1211 at different positions are different, and the inner diameters of the step at different positions are different. Therefore, more specifically, the maximum diameter of the limiting end 1211 is greater than the minimum inner diameter of the step, so as to further ensure that the limiting end 1211 is restricted in its range of motion by the step.

[0054] Understandably, the stop structure restricts the limiting end 1211 within the second cavity 1202, and when the limiting end 1211 abuts against the stop structure, the first cavity 1201 and the second cavity 1202 are separated.

[0055] Specifically, in this embodiment, there is a gap between the limiting end 1211 and the inner wall of the first cavity 1201.

[0056] Understandably, the liquid in the first cavity 1201 enters the second cavity 1202 through the gap, and the gap also prevents the limiting end 1211 from forming friction with the inner wall of the first cavity 1201, thus allowing the floating part 121 to be pressed better.

[0057] In some other embodiments, the diameter of the limiting end 1211 is equal to the inner diameter of the first cavity 1201, and the liquid in the first cavity 1201 can enter the second cavity 1202 through the notch or hole by opening a notch or hole on the limiting end 1211.

[0058] Furthermore, the surface of the stop structure 1203 that abuts against the limiting end 1211 is set as an inclined surface, and the angle formed by the stepped inclined surface and the inner wall of the second cavity 1202 is an acute angle.

[0059] Understandably, the angle α formed by the inclined surface of the step and the inner wall of the second cavity 1202 (e.g., Figure 4 As shown in the figure, setting it to an inclined plane makes it easier to guide the liquid flow to the second chamber.

[0060] Further, please refer to Figure 1 , Figure 2 and Figure 5 The main body 10 includes a liquid storage tank 102, and 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. The liquid guiding comb teeth 12 are set on the liquid storage tank 102.

[0061] 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.

[0062] Moreover, by directly setting the liquid guide comb 12 on the liquid storage tank 102, the liquid flow path is shortened, reducing liquid waste.

[0063] Furthermore, the comb teeth 11 also include conductive comb teeth 13, which are arranged around the groove 104.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] The light can be laser light, etc., and is not limited here.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Compared with the prior art, the care comb provided by this utility model has the following advantages:

[0073] 1. The nursing comb provided in this embodiment of the utility model includes a liquid-guiding comb tooth comprising 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 to each other. 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 step is provided at the connection between the inner walls of the first cavity and the second cavity. The floating member includes a limiting end and a liquid-guiding part. The limiting end can abut against or move away from the stop structure to separate or connect the first cavity and the second cavity. It can be understood that the liquid-guiding comb tooth is set as a telescopic structure. The liquid is dispensing is controlled by telescopic movement. It can not only be used to massage the scalp, but also to apply the nursing liquid to different parts of the hair through the through hole to achieve a uniform application effect.

[0074] 2. The hair care comb provided in this embodiment of the present invention has a floating component that is also provided with a liquid distribution channel that connects to the second cavity. When in use, some of the liquid entering the second cavity also enters the liquid distribution channel and then flows out from the liquid outlet. The liquid flowing out from the liquid outlet can more easily contact the scalp. Therefore, the hair care comb provided in this embodiment can better and more evenly care for the hair.

[0075] 3. In the nursing comb provided in this embodiment of the utility model, the diameter of the liquid guiding part gradually decreases from near the limiting end to far away from the limiting end. Since the size of the opening remains unchanged, when the floating part is pressed, the diameter of the liquid guiding part flush with the opening decreases, thereby leaving a gap between the opening and the liquid guiding part. At this time, the liquid in the second cavity can also flow out from the opening, thereby evenly applying the liquid to the hair in multiple directions.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.
