Description

[0002] The liquid push hair care comb is an innovative healthy hair care product designed to improve the health of hair and promote hair growth. When combing hair, the user uses the liquid push module and the liquid outlet comb teeth to apply the hair care liquid to the scalp and hair roots, achieving the effect of caring for the scalp and hair.

[0003] However, the existing liquid-pushing hair care comb has a relatively simple liquid-pushing control. In order to ensure that the hair care liquid can be evenly applied to the scalp. When combing the hair, the comb is used to comb from front to back, and then the comb is moved to the front to repeat this action. During this action, the comb teeth of the hair care comb will be separated from the scalp, while the liquid-pushing module continues to push the liquid. This will lead to a waste of hair care liquid, which may be used up early and cannot be evenly covered. In addition, too much hair care liquid will remain on the hair during the application process, making the hair look like it has not been cleaned for a long time. Utility Model Content

[0019] Furthermore, the combing head of the hair care comb body is separately connected to the handle part, an elastic member is provided between the combing head and the handle part, and both ends of the elastic member are electrically connected to the resistive sensor.

[0020] By applying the technical solution of the utility model, through distance sensing technology, the liquid pushing unit starts pushing liquid only when the hair care comb is close to the scalp, effectively reducing the waste of hair care liquid, avoiding excessive hair care liquid remaining on the hair, and ensuring that the hair care liquid can be evenly applied to the scalp.

[0033] Reference Figure 1 As shown, a distance-sensing liquid-pushing hair care comb comprises:

[0034] A hair care comb body 100, wherein a combing head 110 of the hair care comb body 100 is provided with a liquid pushing unit 200;

[0035] A central control unit, which is disposed in the hair care comb body 100 and is electrically connected to the liquid pushing unit 200;

[0036] A distance sensing unit, the distance sensing unit is electrically connected to the central control unit;

[0037] Among them, the central control unit controls the liquid pushing unit 200 according to the electrical signal of the distance sensing unit. The design idea of ​​the distance sensing liquid pushing hair care comb is to use distance sensing technology to realize the control of the liquid pushing unit 200. When the user uses the hair care comb, the distance sensing unit can sense the contact between the user and the scalp and transmit the contact signal to the central control unit. The central control unit controls the operation of the liquid pushing unit 200 according to the change of the contact signal, so that the hair care liquid starts to be released only when it contacts the scalp. Through the design of distance sensing, the liquid pushing unit 200 will only start to release the hair care liquid when the user actually contacts the scalp, which effectively reduces the waste of hair care liquid. Since the hair care liquid is only released when it contacts the scalp, it can be ensured that the hair care liquid can be evenly applied to the scalp to improve the hair care effect. The central control unit automatically controls the operation of the liquid pushing unit 200 according to the signal of the distance sensing unit, without the user performing additional operations, simplifying the use process. Through the design of distance sensing, the liquid pushing hair care comb can sense the contact between the user and the scalp, automatically control the release of the hair care liquid, and make the user feel more comfortable during use.

[0038] Reference Figure 2-6 As shown, in implementation case one, the distance sensing unit is an infrared distance measuring sensor. The distance sensing unit uses an infrared distance measuring sensor as a sensing device. The infrared distance measuring sensor uses the emission and reception of infrared light to sense the distance of an object. The infrared distance measuring sensor includes an infrared emitting part and an infrared receiving part. When measuring distance, the central control unit controls the infrared emitting part to emit infrared rays, which are reflected by an object (such as scalp or hair) and then received by the infrared receiving part. When the user uses a hair care comb, the infrared distance measuring sensor emits infrared light and receives the reflected signal of the infrared light. By calculating the time difference or intensity difference of the reflected light, the sensor can determine the contact between the user and the scalp, thereby triggering the central control unit to control the operation of the liquid pushing unit 200.

[0039] The central control unit can use a main control chip of model ZX32F018, which has rich IO ports. The infrared transmitting part and the infrared receiving part are respectively connected to an IO port of the main control chip, and the IO ports output high and low level signals to control the infrared transmitting part and the infrared receiving part. Of course, in other embodiments, the central control unit can also use other integrated chips with the same functions, such as STM32F series single-chip microcomputers, etc., and the utility model does not limit this.

[0040] The infrared distance sensor has a high distance measurement accuracy and can accurately sense the contact between the user and the scalp to achieve precise control of the liquid pushing. The infrared distance sensor has a fast response speed and can sense the contact between the user and the scalp in real time, ensuring that the liquid pushing unit 200 can start or stop pushing the liquid in a timely manner. The working principle of the infrared distance sensor is to sense the distance through the reflection of infrared light. It does not need to directly contact the scalp and will not cause discomfort or harm to the user. The infrared distance sensor has high reliability and stability and can work stably under different environmental conditions to ensure the accuracy and long-term stability of the liquid pushing hair care comb.

[0041] In the first implementation example, the combing head 110 is provided with a lampshade 300, and a PCB lamp board 400 is provided inside the lampshade 300. The PCB lamp board 400 is provided with phototherapy red light beads and an infrared distance sensor. When the user uses the hair care comb, the phototherapy red light beads will emit red light of a specific wavelength, which can penetrate the skin and scalp and be absorbed by cells. The energy of red light can stimulate the vitality of cells, promote blood circulation and metabolism, increase the blood oxygen supply of the scalp, and thus improve the health of the scalp. The infrared distance sensor is used to sense the contact between the user and the scalp.

[0042] By arranging the lampshade 300 and the PCB lamp board 400 on the combing head 110, the red light irradiation and infrared distance measurement functions can be realized, thereby increasing the versatility of the hair care comb.

[0043] In the first implementation example, the infrared band of the infrared ranging sensor is 940nm. The infrared ranging sensor emits infrared light with a wavelength of 940nm, irradiates the light to the target object, and then receives the infrared light signal reflected back by the target object. The sensor measures the time difference or intensity difference of the infrared light, and calculates the distance between the target object and the sensor based on these differences. The use of the 940nm infrared band can provide higher ranging accuracy, allowing the infrared ranging sensor to accurately sense the distance between the target object and the sensor.

[0044] Infrared light in the 940nm infrared band has less absorption in the atmosphere and can work stably under different environmental conditions, providing reliable ranging performance.

[0045] In the second implementation case, the distance sensing unit is a static capacitance sensor. The static capacitance sensor consists of two electrodes. When no object is close, the capacitance value between the electrodes is relatively stable. However, when an object approaches the sensor, the charge of the object will affect the electric field distribution between the electrodes, causing the capacitance value to change. The sensor determines whether the object is close to or in contact with the sensor by measuring the change in capacitance. The static capacitance sensor is used to sense the contact between the user and the scalp. When the user uses a hair comb, the static capacitance sensor can sense the change in capacitance between the user's fingers or hair and the sensor electrodes, thereby determining the contact between the user and the scalp.

[0046] The electrostatic capacitance sensor has high sensitivity and precision, and can accurately sense the contact between the user and the scalp, thus achieving precise liquid pushing control. The electrostatic capacitance sensor can sense the contact between the user and the scalp in real time, has a fast response speed, and can trigger the operation of the liquid pushing unit 200 in a timely manner.

[0047] In the second implementation case, the comb teeth on the comb head 110 are made of metal, and the comb teeth are electrically connected to the electrostatic capacitance sensor. An electrical connection is established between the metal comb teeth and the electrostatic capacitance sensor to form an electrode system of the capacitance sensor. When the user uses the hair care comb, when the hand scalp contacts the metal comb teeth, it will cause the capacitance of the electrostatic capacitance sensor to change. The sensor can determine the contact between the user and the scalp by measuring the change in capacitance. The metal comb teeth serve as the electrodes of the sensor, which can sense the contact between the user and the scalp in real time and achieve precise liquid pushing control. Electrically connecting the metal comb teeth to the electrostatic capacitance sensor can simplify the overall design, reduce the electrical connection lines of the sensor, and improve the reliability and stability of the product.

[0048] In implementation case three, the distance sensing unit is a pressure sensor. The pressure sensor is usually composed of a sensitive element and a signal processing circuit. When the user uses a hair care comb, the sensitive element of the pressure sensor will be subjected to pressure applied by the user's fingers or hair. This pressure will cause the sensitive element to deform or produce electrical signal changes. The signal processing circuit will convert these changes into electrical signals and determine the contact between the user and the scalp based on the changes in the signals. The pressure sensor can accurately sense the pressure applied between the user and the scalp to achieve precise liquid pushing control. The pressure sensor can sense the contact status between the user and the scalp in real time, and quickly convert it into an electrical signal to achieve real-time liquid pushing action.

[0049] In implementation case three, the pressure sensor is located below the comb teeth of the comb head 110. When the user uses a hair care comb, the pressure applied by the fingers or hair on the comb teeth will be transmitted to the pressure sensor below the comb teeth. The pressure sensor can sense this pressure and convert it into a corresponding electrical signal. By detecting the pressure changes below the pressure sensor, the central control unit can judge the user's usage strength and combing action, and control the operation of the liquid pushing unit 200 according to the set threshold. This ensures that the hair care liquid is released only under appropriate pressure, improving the efficiency of the use of the hair care liquid and the user's comfortable experience. Placing the pressure sensor below the comb teeth can accurately sense the changes in pressure applied by the user on the comb teeth when combing the hair, and achieve precise liquid pushing control. Placing the pressure sensor below the comb teeth will not interfere with the user's combing process, providing a more natural and comfortable user experience.

[0050] In the fourth implementation example, the distance sensing unit is a resistive sensor. A resistive sensor is usually composed of a sensing resistor and a signal processing circuit. When a user uses a hair care comb, the sensing resistor above the comb teeth will change due to the pressure applied by the user's fingers or hair. This pressure will cause the resistance value of the sensing resistor to change. The signal processing circuit will convert the change in resistance value into an electrical signal, and judge the contact between the user and the scalp based on the change in the signal.

[0051] In the fourth implementation example, the combing head 110 of the hair care comb body 100 is separately connected to the handle part, and an elastic member is provided between the combing head 110 and the handle part, and the two ends of the elastic member are electrically connected to the resistive sensor. When the user uses the hair care comb, the pressure applied by the fingers or hair on the combing head 110 will cause the elastic member to deform. The deformation of the elastic member will cause the resistance value of the resistive sensor to change. The sensor can determine the contact between the user and the hair care comb by measuring the change in resistance value. By detecting the change in resistance value of the resistive sensor, the central control unit can determine the user's use force and combing action, and control the operation of the liquid pushing unit 200 according to the set threshold value. In this way, it can be ensured that the hair care liquid is released only under appropriate pressure, thereby improving the use efficiency of the hair care liquid and the user's comfortable experience.
