Description

Technical Field

[0001] The utility model relates to a hair care comb. Background Art

[0002] As a daily hair care tool, hair care combs have attracted more and more attention in the market in recent years. Traditional hair care combs mainly use various methods to transfer the liquid in the liquid storage bottle to the comb teeth, so that the nutrient solution is evenly applied to the hair and scalp during the hair combing process. Among them, the most common design is to use a motor to drive the screw to squeeze out the liquid in the liquid storage bottle.

[0003] The motor drives the screw extrusion structure to drive the screw forward through the rotation of the motor, thereby squeezing the liquid in the liquid storage bottle, so that the liquid enters the liquid guide comb teeth through the catheter and is evenly distributed on the hair.

[0004] However, the motor-driven screw extrusion method also has some shortcomings in actual use. First, the structure of the motor and screw is complex, the manufacturing cost is high, and the weight and volume of the product are increased, making it inconvenient to carry. Secondly, the motor will generate noise when running, which may affect the user experience. In addition, the long-term use of the motor and screw may cause mechanical wear, requiring regular maintenance and replacement of parts, which increases the cost of use and the difficulty of maintenance. Utility Model Content

[0005] The utility model aims to provide a hair care comb which can extract liquid in a liquid storage bottle and introduce the liquid into liquid guide comb teeth, thereby improving the convenience of use and the utilization rate of the liquid.

[0006] The purpose of the utility model is achieved in this way:

[0007] A hair care comb, comprising a comb body, a liquid extraction device and liquid-conducting comb teeth for discharging liquid, wherein the liquid-conducting comb teeth are arranged on the comb body at intervals;

[0008] The comb body is provided with a liquid storage bottle installation cavity, and the comb body has an opening corresponding to the position of the liquid storage bottle installation cavity;

[0009] The liquid extraction device is arranged in the comb body, and comprises a liquid extraction port and a liquid discharge port for connecting to a liquid storage bottle, wherein the liquid discharge port is connected to the liquid guiding comb teeth.

[0010] Prevent leakage: The valve of the liquid extraction device can be automatically closed when not in use to prevent liquid from leaking out of the liquid storage bottle. This design greatly improves the sealing of the product, avoids liquid waste and comb body contamination, and maintains hygiene and cleanliness during use.

[0011] Easy to use: Compared with the traditional method of using a motor to drive a screw to squeeze liquid, the liquid extraction method of this utility model is simpler. Users do not need to perform complicated operations, but only need to easily extract the liquid to deliver the nutrient solution to the liquid-guiding comb teeth, achieving a convenient hair care experience.

[0012] Uniform liquid distribution: The liquid extraction device of the utility model can ensure that the liquid is evenly output to the liquid guide comb teeth, so that the nutrient solution is evenly distributed on the hair and scalp during the combing process, thereby improving the hair care effect and ensuring that each hair strand can be fully nourished.

[0013] Improve liquid utilization: Compared with the traditional squeezing method, the liquid extraction method can more thoroughly extract the liquid in the liquid storage bottle, reduce residue, avoid waste, thereby improving the utilization rate of the liquid and maximizing the user's use value.

[0019] Furthermore, the liquid extraction port of the liquid extraction device is provided with a valve, and the valve includes a shell, a ball and a spring. The shell has a liquid conducting channel, and the ball and the spring are placed in the liquid conducting channel. The elastic force of the spring pushes the ball against the entrance of the liquid conducting channel so that the ball closes the entrance of the liquid conducting channel. The liquid extraction port of the liquid extraction device is connected to the outlet of the liquid conducting channel.

[0020] Effective anti-leakage: The valve design uses the elastic force of the spring to push the ball to the entrance of the liquid guide channel to achieve automatic closure. When the hair care comb is not in use, the ball tightly closes the entrance of the liquid guide channel under the action of the spring to prevent accidental leakage of the liquid in the liquid storage bottle. This design greatly improves the sealing of the product, prevents liquid waste and comb body contamination, and keeps the comb clean.

[0021] Automatic opening and closing: During use, the liquid extraction device is connected to the outlet of the liquid guide channel through the liquid extraction port. When the user performs the liquid extraction operation, the liquid pressure pushes the ball away from the inlet, allowing the liquid to pass through; after the operation is completed, the elastic force of the spring automatically pushes the ball back to close the entrance of the liquid guide channel, without the need for manual adjustment by the user, and the operation is simple and quick.

[0022] Even liquid distribution: The automatic control mechanism of the valve ensures that the liquid can flow smoothly into the liquid-guiding comb teeth when needed, ensuring precise control and even output of the liquid, so that the nutrient solution is evenly distributed on the hair and scalp during the combing process, significantly improving the hair care effect.

[0023] Prevent backflow: The valve design not only prevents leakage, but also effectively prevents liquid backflow. The ball fits tightly to the entrance of the liquid guide channel under the action of the spring, preventing the liquid from flowing back to the liquid storage bottle during the combing process, ensuring the consistency and continuity of liquid delivery.

[0024] Simplify the structure and reduce costs: Compared with the complex structure of the motor and screw, the mechanical structure of the ball and spring is simpler, which reduces the manufacturing cost and product weight, while reducing the product volume and improving portability, making it easier for users to carry and use.

[0025] Easy to maintain: Due to the simple structure of the valve, maintenance is convenient and there are few parts. The detachable cover design makes it easier to clean and replace the liquid storage bottle and valve, extending the service life of the product and reducing maintenance costs.

[0026] Silent operation: This utility model adopts a motor-free design to avoid the noise generated by the operation of the motor, providing users with a quieter use environment and improving the user experience.

[0027] Furthermore, it also includes a liquid guiding block, which is arranged in the comb body, and the liquid guiding block is provided with a liquid guiding main channel and liquid guiding branch channels, and the number of the liquid guiding branch channels matches the number of the liquid guiding comb teeth;

[0029] Evenly distribute liquid: The liquid guide block is equipped with a main liquid guide channel and multiple liquid guide branch channels to ensure that the liquid can be evenly distributed to each liquid guide comb tooth after being discharged from the liquid extraction device. In this way, during use, the nutrient solution can be evenly applied to the hair and scalp, improving the hair care effect.

[0030] Improve liquid delivery efficiency: Through the main channel and branch channel structure of the liquid guide block, the liquid can be quickly and efficiently transported from the liquid pumping device to each liquid guide comb tooth, reducing the resistance and time of liquid delivery and improving the use efficiency.

[0031] Optimized structure to avoid blockage: The main channel and branch channels of the liquid guide block are reasonably designed, which can effectively prevent blockage during liquid transportation and ensure that the liquid can flow smoothly every time it is used.

[0032] Simplified liquid channel design: The liquid delivery path is concentrated in the liquid guide block. By rationally designing the main liquid guide channel and branch channels, the liquid delivery structure is simplified, making the internal design of the entire comb body more concise, reducing manufacturing complexity and

[0033] Furthermore, a liquid separation and concentration port is provided at the center of the liquid guiding block, the liquid guiding branch channels are arranged at intervals on the liquid guiding block and are located at the periphery of the liquid separation and concentration port, and the inlets of the liquid guiding branch channels are connected to the liquid separation and concentration port.

[0034] Even liquid distribution: A liquid distribution center is set in the center of the liquid guide block to ensure that the liquid is first concentrated in the center of the liquid guide block, and then evenly distributed to each liquid guide branch channel through the liquid distribution center. This design makes the liquid discharge time of each liquid guide comb closer, ensuring that the nutrient solution can be evenly applied to the hair and scalp, improving the hair care effect.

[0035] Improve liquid delivery efficiency: Through the reasonable layout of the liquid separation and concentration ports and branch channels, the liquid can be quickly and efficiently discharged from the liquid extraction device and distributed to each liquid guide comb. This reduces the delay in liquid delivery, improves the efficiency of use, and ensures the timeliness of liquid supply during use.

[0036] Furthermore, the liquid guiding block is provided with a liquid inlet and a concentrated liquid inlet, and the liquid discharge port of the liquid pumping device is connected to the liquid inlet and a concentrated liquid inlet;

[0037] The inlet of the main liquid-conducting channel is connected to the liquid-inlet central port, and the outlet of the main liquid-conducting channel is connected to the liquid-separation central port.

[0038] Efficient liquid delivery: The liquid inlet and concentration port of the liquid guide block is connected to the liquid outlet of the liquid pumping device to ensure that the liquid can quickly and smoothly enter the liquid guide block. The liquid is transported to the liquid separation and concentration port through the liquid guide main channel, and then distributed to each liquid guide branch channel, thereby achieving efficient liquid delivery.

[0039] Even liquid distribution: The liquid enters the main liquid channel from the liquid inlet, is concentrated at the liquid distribution port, and then evenly distributed to the liquid branch channel, ensuring that the liquid discharge time of each liquid guide comb tooth is close. This design ensures that the nutrient solution is evenly applied to the hair and scalp, improving the hair care effect.

[0040] Avoid blockage: The reasonable design of the liquid inlet, liquid guide channel and liquid separation port inside the liquid guide block ensures smooth liquid delivery, reduces the risk of blockage in the liquid path, ensures smooth flow of liquid every time it is used, and improves reliability of use.

[0041] Optimized structural design: The layout of the liquid inlet concentrated port, the liquid guide channel and the liquid separation concentrated port inside the liquid guide block makes the liquid delivery path more concise and reasonable, reduces the manufacturing complexity and cost, and improves the overall structural stability of the product.

[0042] Furthermore, the surface of the liquid-conducting block is provided with the liquid-conducting branch channel, and the bottom surface of the liquid-conducting block is provided with the liquid-conducting main channel.

[0043] Liquid flow path optimization: The liquid-conducting branch channels are arranged on the surface of the liquid-conducting block, while the liquid-conducting main channel is arranged on the bottom surface, which can effectively simplify the flow path of the liquid from the main channel to the branch channel and improve the efficiency of the liquid flow.

[0044] Uniform distribution: This design ensures that the liquid can be quickly and evenly distributed to each liquid guide branch channel after entering the liquid guide block, further ensuring that the liquid output of each liquid guide comb tooth is consistent.

[0045] Reduce resistance and loss: The optimized channel design reduces the resistance and energy loss during liquid flow, allowing the liquid to reach each liquid-guiding comb tooth more smoothly, thereby improving the overall use effect.

[0046] The structure is simple and easy to manufacture: the branch channels and the main channel are respectively arranged on different planes of the liquid guiding block, so that the structure of the liquid guiding block is simpler, the manufacturing and assembly process is more convenient, and it is conducive to production and maintenance.

[0047] Furthermore, the liquid conducting block is a silicone liquid conducting block.

[0048] Improved sealing and durability: Silicone material has good elasticity and sealing. By using silicone blocks to design the liquid guide path, liquid leakage can be effectively prevented and the sealing of the system can be enhanced. At the same time, the durability and wear resistance of silicone materials increase the service life of the liquid guide block.

[0049] Furthermore, a membrane sheet for closing the outlet of the liquid-conducting branch channel is provided at a position on the bottom surface of the liquid-conducting block corresponding to the outlet of the liquid-conducting branch channel, and the membrane sheet is provided with a cutting opening.

[0050] Effectively prevent leakage: The diaphragm with a cutout is set at the outlet of the liquid-conducting branch channel. When the hair care comb is not in use, the diaphragm can effectively close the outlet of the liquid-conducting branch channel. Since the pressure of the nutrient solution is not enough to break through the cutout, leakage of the liquid in a static state is avoided, ensuring that the liquid in the comb body remains stable.

[0051] Precise control of liquid output: When the pumping device is running, the pressure of the nutrient solution increases, enough to break through the cut on the diaphragm, allowing the liquid to flow out of the branch channel smoothly and output through the comb teeth. This design ensures that the liquid is output only when needed, accurately controls the amount of liquid used each time, and avoids waste.

[0052] Enhanced sealing: The design of the cut-out diaphragm further enhances the sealing of the liquid delivery system, preventing outside air from entering the liquid channel, avoiding the liquid from becoming ineffective due to oxidation or contamination, and ensuring the quality and efficacy of the nutrient solution.

[0053] Easy to use: Users do not need to manually adjust or operate during use. Once the pumping device is started, the pressure of the nutrient solution will automatically break through the cut on the diaphragm to achieve liquid output. It is easy to operate and provides a good user experience.

[0054] Reduce maintenance costs: Since the diaphragm design can effectively prevent liquid leakage and contamination, users do not need to frequently clean and maintain it after daily use, which reduces the use and maintenance costs and improves the overall economy of the product.

[0055] Furthermore, the central position of the surface of the liquid-conducting block is provided with the main liquid-conducting channel, the end of the main liquid-conducting channel is closed, and the end of the main liquid-conducting channel is provided with flow-conducting holes corresponding to the number of the liquid-conducting branch channels, and the flow-conducting holes form the outlet of the main liquid-conducting channel;

[0056] The bottom surface of the liquid guiding block is located at the periphery of the main liquid guiding channel and is provided with the liquid guiding branch channels at intervals. The flow guiding holes are communicated with the inlets of the liquid guiding branch channels.

[0057] Evenly distribute the liquid: By setting the main liquid conduction channel at the center of the surface of the liquid conduction block and opening a diversion hole at its end, it can be ensured that after the nutrient solution enters the main liquid conduction channel, it is evenly distributed to each liquid conduction branch channel through the diversion hole, thereby achieving even distribution of the liquid.

[0058] Liquid flow path optimization: This design simplifies the path of the liquid from the main channel to the branch channel, effectively reduces the resistance and energy loss of the liquid during the flow process, and improves the liquid delivery efficiency.

[0059] Stability and reliability: By arranging branch channels of liquid guide at intervals on the bottom surface of the liquid guide block and connecting them with the guide holes, it can be ensured that the liquid flows smoothly from the main liquid guide channel to each branch channel, ensuring that the liquid output of each liquid guide comb tooth is consistent, thereby improving the overall use effect.

[0060] Reduce the risk of leakage: The closed design at the end of the main liquid guide channel and the setting of the diversion holes can effectively control the flow path of the liquid, reduce the risk of leakage, and maintain the sealing of the liquid guide system.

[0061] Compact structure and easy to manufacture: This design makes the liquid guide block structure more compact, and the manufacturing and assembly process are simpler, which is conducive to improving production efficiency and reducing manufacturing costs.

[0062] Improve service life: The optimized liquid flow path and efficient liquid distribution method can reduce wear and aging during liquid delivery and improve the service life of the hair care comb.

[0063] Through this design, the liquid delivery system of the hair care comb can distribute the nutrient solution to each liquid-guiding comb tooth more efficiently and evenly, ensuring stable and uniform liquid flow during use, thereby improving product performance and user experience.

[0064] Furthermore, the liquid-conducting comb teeth are hollow cylinders, a liquid outlet hole is formed on a side wall of the hollow cylinder at a position higher than the bottom end thereof, and an upper port of the hollow cylinder abuts against an outlet of a corresponding liquid-conducting branch channel.

[0065] Avoid clogging: In the traditional design, the liquid outlet is located at the bottom of the liquid-guiding comb teeth, which is easily blocked by the scalp when combing hair, resulting in the liquid not being able to flow out smoothly. The utility model sets the liquid outlet at a position where the side wall of the hollow cylinder is higher than the bottom, avoiding direct contact of the scalp with the liquid outlet, thereby effectively preventing the liquid outlet from being blocked and ensuring smooth liquid output.

[0066] Improve the uniformity of liquid distribution: The liquid outlet is set at a high position on the side wall of the hollow cylinder, so that the liquid can flow out from a higher position, ensuring that the liquid can be evenly distributed on the hair and scalp during the combing process, optimizing the liquid application effect and enhancing the hair care function.

[0067] Reduce liquid waste: The high-position liquid outlet design avoids the waste of liquid when it flows out directly from the bottom, so that more nutrient solution can be effectively utilized, improves the efficiency of liquid use, and reduces unnecessary waste.

[0068] Enhanced infusion stability: The hollow cylindrical structure and the side wall liquid outlet hole design allow the liquid to flow out more smoothly during the combing process, avoiding liquid splashing or uneven application caused by the combing action, ensuring stability and comfort during use.

[0069] Simplified cleaning and maintenance: The hollow cylinder and high-position liquid outlet design on the side wall make the liquid channel simpler, reducing the risk of liquid residue and blockage, making it easier for users to clean and maintain after use, ensuring the hygiene and smooth flow of the liquid channel and extending the service life of the product.

[0070] Protective diaphragm: The upper port of the hollow cylinder rests against the diaphragm, which prevents the diaphragm from being affected by external physical contact, effectively protects the diaphragm, prolongs its service life, and ensures its sealing performance and leak-proof effect.

[0071] Improve product reliability: By optimizing the position and structural design of the liquid outlet, the risk of liquid outlet blockage and liquid leakage is reduced, the overall reliability of the product is improved, and the best effect can be obtained every time it is used.

[0072] Optimize user experience: The improved liquid-guiding comb tooth design makes the liquid output smoother and more uniform, reduces liquid waste and unnecessary leakage that may occur during the combing process, improves the user experience, and enables users to enjoy efficient, convenient and high-quality hair care services every time they use it.

[0073] Furthermore, it also includes a liquid storage bottle, which includes a bottle body with an open top and a piston, the piston is placed in the inner cavity of the bottle body through the open mouth, a liquid storage cavity is formed between the piston and the inner cavity of the bottle body, and a plug connector connected to the liquid storage cavity is provided at the bottom of the bottle body;

[0074] The liquid storage bottle is placed in the liquid storage bottle installation cavity, and the plug connector is inserted into the entrance of the liquid guide channel. The plug connector overcomes the elastic force of the spring to push the ball to leave the entrance of the liquid guide channel, so that the liquid guide channel is connected to the plug connector, and a seal is formed between the plug connector and the entrance of the liquid guide channel.

[0075] Ensure the stability of liquid delivery: The design of the liquid storage bottle and the plug connector ensures the sealing of the liquid delivery system. When the plug connector is inserted into the entrance of the liquid guide channel and overcomes the elastic force of the spring to push the ball out of the entrance of the liquid guide channel, a reliable sealing connection is formed to ensure that there will be no leakage during the liquid delivery process, thereby improving the stability and reliability of the system.

[0076] Realize negative pressure extraction: When the extraction device extracts the nutrient solution in the storage bottle, the negative pressure generated can drive the piston to move. This negative pressure mechanism ensures that no matter what angle the hair care comb is at, the negative pressure can effectively extract the liquid in the storage bottle, ensuring the continuity and consistency of the liquid delivery process, regardless of the angle of use.

[0077] Enhanced flexibility of use: Since the liquid extraction device can work effectively at any angle, users do not need to worry about the problem of not being able to extract liquid when using the hair care comb. This design greatly improves the flexibility and convenience of use, allowing users to easily use the hair care comb in any posture, improving the user experience.

[0078] Improve liquid utilization: The piston design in the liquid storage bottle can ensure that the liquid is fully extracted under the action of negative pressure, reduce liquid residue, improve the utilization rate of the nutrient solution, ensure that every drop of liquid can be effectively utilized, and improve the use efficiency.

[0079] Easy to replace and maintain: The liquid storage bottle can be easily placed in the liquid storage bottle installation cavity, and the plug connector is inserted into the liquid guide channel to form a sealed connection. This design not only makes it easy for users to replace the liquid storage bottle, but also simplifies the system maintenance process, ensuring the long-term reliable operation of the liquid delivery system.

[0080] Prevent air from entering: The sealed connection formed between the plug connector and the entrance of the liquid guide channel effectively prevents air from entering the liquid delivery system, avoids liquid oxidation and contamination caused by air entry, and ensures the quality and efficacy of the nutrient solution.

[0081] Improve product durability: By ensuring the sealing and stability of the liquid delivery system, the risk of liquid leakage and system damage is reduced, the service life of the product is extended, and the overall durability and reliability of the product are improved.

[0082] Furthermore, the liquid pumping device is a peristaltic pump.

[0083] Precise control of liquid output: Peristaltic pumps use controllable peristaltic motion to extract liquid, and can accurately control the amount of liquid output each time. Compared with traditional liquid extraction methods, such as pressure extrusion or gravity flow, peristaltic pumps can more accurately adjust the amount of liquid output, ensuring that the expected amount of liquid is obtained each time it is used, improving the product's efficiency and user experience.

[0084] Fast liquid delivery: The peristaltic pump has a high liquid delivery rate, which can quickly draw liquid from the liquid storage bottle and deliver it to the liquid guide comb teeth, reducing waiting time. Users do not need to wait for a long time for the hair care liquid to flow out when using the hair care comb, which improves the convenience and efficiency of use.

[0085] Applicable to a variety of liquids: Peristaltic pumps are suitable for a variety of liquids, including viscous liquids and easily oxidized liquids. Whether it is liquid hair care products or other care liquids, they can be accurately extracted and transported through peristaltic pumps, which enhances the applicability and flexibility of the product.

[0086] Reduce liquid residue: The peristaltic pump has good adsorption performance and can fully extract the liquid in the liquid storage bottle, reducing the possibility of liquid residue. This ensures that the liquid resources in the liquid storage bottle can be fully utilized every time, reducing waste and saving costs.

[0087] Improve stability and reliability: The peristaltic pump has a simple structure, stable operation and a long service life. Using a peristaltic pump as a pumping device can improve the stability and reliability of the product, reduce the possibility of failure and maintenance, and extend the service life of the product.

[0088] Improved user experience: Since the peristaltic pump can quickly and accurately deliver liquid to the liquid-guiding comb teeth, users can more easily control the output of liquid when using the hair care comb, avoiding long waiting times and uneven liquid, and improving the comfort and convenience of use.

[0089] The beneficial effects of the utility model are as follows:

[0090] Compared with the traditional method of using a motor to drive a screw to squeeze liquid, the present invention is more convenient in extracting liquid. Users do not need to perform complicated operations, but only need to easily extract liquid to deliver the nutrient solution to the liquid-guiding comb teeth, thus achieving a convenient hair care experience. Moreover, the liquid extraction device can ensure that the liquid is evenly output to the liquid-guiding comb teeth, so that the nutrient solution is evenly distributed to the hair and scalp during the combing process, thereby improving the hair care effect and ensuring that each hair strand can be fully nourished.

[0091] In the utility model, liquid enters the liquid guide channel from the liquid inlet, and is evenly distributed to the liquid guide branch channel after being concentrated at the liquid separation concentrated port, ensuring that the liquid discharge time of each liquid guide comb tooth is close. This design ensures that the nutrient solution is evenly applied to the hair and scalp, improving the hair care effect.

[0092] The utility model arranges the branch channel and the main channel on different planes of the liquid guiding block, so that the structure of the liquid guiding block is simpler, the manufacturing and assembly process is more convenient, and it is beneficial to production and maintenance.

[0093] The utility model effectively prevents liquid leakage: a diaphragm with a cutout is arranged at the outlet of the liquid-conducting branch channel. When the hair care comb is not in use, the diaphragm can effectively close the outlet of the liquid-conducting branch channel. Since the pressure of the nutrient solution is not enough to break through the cutout, leakage of the liquid in a static state is avoided, ensuring that the liquid in the comb body remains stable. When the liquid extraction device is running, the pressure of the nutrient solution increases, which is enough to break through the cutout on the diaphragm, allowing the liquid to smoothly flow out of the liquid-conducting branch channel and be output through the liquid-conducting comb teeth. This design ensures that the liquid is output only when needed, accurately controls the amount of liquid used each time, and avoids waste.

[0094] The utility model arranges the liquid outlet hole at a position where the side wall of the hollow cylinder is higher than the bottom end, thereby preventing the scalp from directly contacting the liquid outlet hole, thereby effectively preventing the liquid outlet hole from being blocked and ensuring smooth output of the liquid.

[0095] In the utility model, when the liquid extraction device extracts the nutrient solution in the liquid storage bottle, the negative pressure generated can drive the piston to move. This negative pressure mechanism enables the negative pressure to effectively extract the liquid in the liquid storage bottle regardless of the angle of the hair care comb, thereby ensuring the continuity and consistency of the liquid delivery process without being restricted by the use angle.

[0096] The utility model: the peristaltic pump realizes the extraction of liquid by controllable peristaltic motion, and can accurately control the output amount of liquid each time. Compared with the traditional liquid extraction method, such as pressure squeezing or gravity flow, the peristaltic pump can more accurately adjust the liquid output, ensuring that the expected amount of liquid can be obtained each time it is used, improving the use efficiency and user experience of the product, and the peristaltic pump has a high liquid delivery rate, which can quickly extract the liquid from the liquid storage bottle and deliver it to the liquid guide comb teeth, reducing the waiting time. When using the hair care comb, the user does not need to wait for a long time for the hair care liquid to flow out, which improves the convenience and efficiency of use.

[0129] Working principle:

[0130] The user installs the liquid storage bottle 10 in the liquid storage bottle installation cavity 11 , and the plug connector 104 of the liquid storage bottle 10 is inserted into the entrance of the liquid guiding channel 511 .

[0131] The role of peristaltic pump:

[0132] The peristaltic pump is a type of liquid pumping device that extracts the nutrient solution from the storage bottle and transports it to the liquid guide comb teeth by squeezing the hose.

[0133] The peristaltic pump has precise control capabilities and can adjust the flow and pressure of the liquid as needed to ensure that the liquid flows evenly into the liquid-guiding comb teeth.

[0134] Liquid delivery of the liquid guide comb:

[0135] When the user uses the hair care comb, the liquid extraction device (peristaltic pump) is activated and draws nutrient solution from the liquid storage bottle through the liquid extraction port.

[0136] The nutrient solution enters the main liquid guiding channel through the liquid discharge port of the liquid pumping device, and is then distributed to each liquid guiding comb tooth through the liquid guiding branch channels.

[0137] The design of the liquid-guiding comb teeth allows the liquid to flow out evenly from the liquid outlet and be applied directly to the scalp and hair.

[0138] Liquid supply to the reservoir bottle:

[0139] The nutrient solution in the liquid storage bottle is subjected to the negative pressure of the liquid pumping device through the design of the piston and the liquid storage chamber, so that it is sucked and transported to the liquid guide comb teeth.

[0140] The nutrient solution is evenly flowed through the hair care comb:

[0141] First, the nutrient solution is stored in the liquid storage bottle inside the comb body. When the hair care comb is used, the peristaltic pump is activated and starts to extract the nutrient solution from the liquid storage bottle. The peristaltic pump, with its unique working method (moving the liquid by squeezing the hose), can accurately control the flow rate and pressure of the liquid to ensure the uniformity and continuity of the flow.

[0142] The nutrient solution is then transported to the liquid guide block. Here, the nutrient solution first enters the liquid inlet and then flows into the main liquid guide channel. Through the main liquid guide channel, the liquid is evenly distributed to each liquid guide branch channel. The design of these branch channels matches the number of liquid guide comb teeth to ensure that each comb tooth can obtain enough nutrient solution.

[0143] Next, the nutrient solution flows into the liquid-conducting comb teeth through the branch channels. Each comb tooth is a hollow cylinder with a liquid outlet opening on the side wall. Since the upper port of the hollow cylinder contacts the diaphragm of the liquid-conducting branch channel, the liquid can smoothly and evenly flow out through the liquid outlet hole. This diaphragm has a cutout, which not only plays a sealing role, but also ensures that the liquid can flow out smoothly when necessary.

[0144] Through the above steps, the hair care comb can ensure that the nutrient solution is evenly distributed on the scalp and hair during the entire use process, achieving the ideal care effect. This finely controlled process not only improves the efficiency of liquid use, but also ensures the even distribution of the liquid, so that the scalp and hair can obtain sufficient nutrition.
