[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. It should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] This utility model discloses a multi-mode massage comb with multiple working modes such as massage mode, oil control mode, revitalization mode and all-effect mode, which can meet the different hair care needs of users and eliminate the need to purchase different types of massage combs or hair growth combs.

[0031] In massage mode, the vibration motor 110 and negative ion generator 111 are activated. Massage mode is suitable for regular hair combing. In massage mode, the massage comb vibrates in a cycle, providing a cyclical massage stimulation when the comb teeth touch the scalp, promoting blood circulation in the scalp, relaxing head muscles, and relieving stress and fatigue. At the same time, the negative ions generated by the negative ion generator 111 neutralize the positive charge in the hair, eliminate static electricity, smooth dry hair, and make it smooth. Combing the hair smooth and relieving fatigue, it is combined with the essence guided to the scalp by the liquid-guiding comb teeth 102, massaging and soothing the scalp and promoting nutrient absorption.

[0032] In oil control mode, the negative ion generator 111, EMS microcurrent, and LED blue light source are activated. This mode is suitable for oily hair. The blue light can penetrate deep into the hair follicle roots to clean up excess oil secretion. The EMS microcurrent simulates the body's own biocurrent, which enhances the vitality of scalp cells, muscles, and fascia. Negative ions neutralize the positive charge in the hair, making it smooth, improving the scalp's water-oil balance, controlling oil, preventing hair loss, and reducing dandruff.

[0033] In Revitalization Mode, the negative ion generator 111, EMS microcurrent, LED red light source, and low-energy laser are activated. The red light penetrates the hair and skin to promote cell regeneration and activate effective ingredients. The low-energy laser promotes blood circulation and the release of growth factors, stimulating hair follicle redevelopment. The EMS microcurrent enhances the vitality of scalp cells and muscles, revitalizing hair follicles.

[0034] In full-effect mode, the vibration motor 110, negative ion generator 111, EMS microcurrent, LED red light source, LED blue light source, and low-energy laser are activated. The dual light source of red and blue light waves provides care, while the low-energy laser promotes blood circulation and the release of growth factors. The EMS microcurrent enhances the vitality of scalp cells and muscles, and the liquid-guiding comb teeth 102 introduce the medicine. Vibration massage provides comprehensive care for scalp cells and hair, and periodic full-effect head care comprehensively improves scalp microcirculation.

[0035] like Figure 1-3 As shown, a multi-mode massage comb includes a comb body 100, a handle 200, and a drive circuit. The comb body 100 is provided with metal comb teeth 101, liquid-guiding comb teeth 102, a negative ion generator 111, and an irradiation area 104. The metal comb teeth 101 are divided into group A comb teeth 105 and group B comb teeth 106. Group A comb teeth 105 are arranged in a circle on the inner side of the comb body 100 in the same direction as the handle 200. Group B comb teeth 106 are arranged on the outer side of the comb body 100 and are surrounded by a number of layers of comb teeth. An irradiation area 104 is provided between group A comb teeth 105 and group B comb teeth 106. A red light source 107, a blue light source 108, and a laser light source 109 are provided in the irradiation area 104. Liquid-guiding comb teeth 102 are provided in the circles formed by group A comb teeth 105. At the same time, a negative ion probe is provided on the comb body 100, which ionizes the air to generate negative ions.

[0036] EMS microcurrents contact the hair through the metal comb teeth 101, allowing the EMS microcurrents to enter the body from the scalp. The microcurrents then flow back from the conductive sensing strip 201 in contact with the palm of the arm holding the handle 200, forming a complete microcurrent circuit. The ends of the liquid-guiding comb teeth 102 are equipped with ball bearings. When the massage comb is combing the hair, the essence in the liquid-guiding comb teeth 102 is guided to the scalp and hair as the ball bearings continuously roll on the scalp and hair, and is absorbed by the scalp.

[0037] like Figure 3 , Figure 4As shown, vibration motors 110 are installed at both the front and rear ends of the comb body 100. When the two vibration motors 110 vibrate synchronously, the massage comb vibrates regularly in a cycle. A medicine box 112 is installed inside the comb body 100. The liquid guide comb teeth 102 are embedded in the liquid outlet of the medicine box 112 and the surface of the comb body 100. The end of the liquid guide comb teeth 102 is provided with a ball, which dispenses liquid evenly when rolling. An inlet pipe 113 is provided on the medicine box 112. A silicone sealing plug 114 is provided on the inlet pipe 113. The sealing plug is opened to replenish the essence. A battery 202 and a negative ion generator 111 are installed inside the handle 200. The negative ion generator 111 is connected to a negative ion probe, which discharges and ionizes the tip of the negative ion probe to generate negative ions.

[0038] like Figure 4 As shown, a function indicator light 115, a first button 116, and a second button 117 are provided on the back of the massage comb. The first button 116 and the second button 117 output signals to the control chip 301 to switch the massage comb mode. Press and hold the first button 116 to turn the massage comb on or off, and press the first button 116 to cycle through the modes. The second button 117 selects the intensity of the massage level, and the function indicator light 115 indicates the corresponding function.

[0039] like Figure 5 As shown, a drive circuit is provided inside the comb body 100. The drive circuit includes a control chip 301, a micro-current control circuit 302, a negative ion generation control circuit 303, a vibration control circuit 304, and a red and blue light control circuit 305. The output terminal of the micro-current control circuit 302 is connected to a conductive sheet, which is connected to the metal comb teeth 101. The micro-current control circuit 302 controls the output micro-voltage to the metal comb teeth 101 to form a micro-current on the metal comb teeth 101. The EMS micro-current generated when the comb teeth comb the hair stimulates the scalp cells. The micro-current control circuit 302 controls the flow of the EMS micro-current on the metal comb teeth 101. The negative ion generation control circuit 303 is connected to the negative ion generator 111 and controls the circuit of the negative ion generator 111 to start the negative ion generator. 111 generates negative ions, and the negative ion generation control circuit 303 controls the start and stop of the negative ion generator 111; the vibration control circuit 304 is connected to the negative terminal of the vibration motor 110, and controls the conduction of the circuit of the vibration motor 110 to start the vibration motor 110 to vibrate and massage the scalp; the vibration control circuit 304 controls the start and stop of the vibration motor 110; the red and blue light control circuit 305 includes a red light control circuit 306 and a blue light control circuit 307. The red light control circuit 306 is connected to the negative terminals of the red light source 107 and the laser source 109, and controls the conduction of the circuit of the red light source 107 and the laser source 109 to emit red light and low-energy laser; the blue light control circuit 307 is connected to the negative terminal of the blue light source 108, and controls the conduction of the circuit of the blue light source 108 to emit blue light.

[0040] The control chip 301 is connected to the microcurrent control circuit 302, the negative ion generation control circuit 303, the vibration control circuit 304, and the red and blue light control circuit 305 respectively. The control chip 301 can output signals to control the conduction of each circuit, thereby controlling the operation of each component.

[0041] like Figure 6 As shown, in this embodiment, the control chip 301 uses chip U4, which is powered by a 3.3V DC voltage and has 24 pins.

[0042] like Figure 8 As shown, the negative ion generation control circuit 303 includes a transistor Q10. The base of the transistor Q10 is connected to the chip U4, the emitter of the transistor Q10 is connected to the ground point, the collector of the transistor Q10 is connected to the negative terminal of the negative ion generator 111, and the positive terminal of the negative ion generator 111 is connected to the battery 202BAT. The chip U4 outputs a signal ION to turn on the transistor Q10, so that the negative ion generator 111 forms a circuit and starts the negative ion generator 111 to generate negative ions at the negative ion tip 103.

[0043] like Figure 8 As shown, the vibration control circuit 304 includes a transistor Q11. Two vibration motors 110 are connected in parallel on the circuit. The positive terminal of the vibration motor 110 is connected to the battery 202BAT, the negative terminal of the vibration motor 110 is connected to the collector of the transistor Q11, the base of the transistor Q11 is connected to the chip U4, and the emitter of the transistor Q11 is connected to the ground point. The chip U4 outputs a signal motor to turn on the transistor Q11 to form a circuit, start the vibration motor 110, and make the massage comb vibrate to massage the scalp.

[0044] like Figure 7 As shown, the red and blue light control circuit 305 includes a red light control circuit 306 and a blue light control circuit 307. Several red LEDs and laser diodes are connected in parallel. In this embodiment, the massage comb uses eight 660nm wavelength red LEDs, eight 460nm wavelength blue LEDs, and six 550nm wavelength laser diodes as the red light source 107, blue light source 108, and laser source 109, respectively. Figure 2 Red light source 107 and blue light source 108 are staggered in pairs, with laser light source 109 interspersed throughout. In the circuit setup, both the red LED and the laser diode are controlled by the red light control circuit 306. The red LED and the laser diode are turned on together. The positive terminals of the red LED and the laser diode are connected to a 3V DC voltage, and the negative terminals of the red LED and the laser diode are connected to the collector of transistor Q3. The base of transistor Q3 is connected to chip U4, and the emitter of transistor Q3 is connected to ground. Chip U4 outputs the signal RED to conduct transistor Q3, turning on the red LED and the laser diode, emitting red light with a wavelength of 660nm and low-energy laser light with a wavelength of 550nm.

[0045] Similarly, several blue LEDs are connected in parallel. The positive terminal of the blue LED is connected to a 3V DC voltage, the negative terminal of the blue LED is connected to the collector of transistor Q4, the base of transistor Q4 is connected to chip U4, and the emitter of transistor Q4 is connected to ground. Chip U4 outputs a signal BLUE to turn on transistor Q4, thus turning on the blue LED and emitting blue light with a wavelength of 460nm.

[0046] like Figure 9 As shown, the micro-current control circuit 302 includes a micro-voltage circuit 308 and a micro-current circuit 309. The micro-voltage circuit 308 filters out interference from the battery voltage and outputs a constant voltage. Simultaneously, the output voltage is controlled by the chip, thereby adjusting the magnitude of the output micro-current. The micro-voltage circuit 308 includes a transistor Q8, a Zener diode D2, an inductor L1, and a capacitor C15. Inductor L1 and Zener diode D2 are connected in series. Inductor L1 is connected to the battery 202BAT to filter out interference from the battery voltage and output the micro-voltage SY-V required for the micro-current. Capacitor C15 is connected in parallel at the output terminal. The collector of transistor Q8 is connected to the other end of inductor L1, the emitter of transistor Q8 is connected to ground, and the base of transistor Q8 is connected to resistor R39 and then to chip U4. Chip U4 outputs the signal SY_PWM. Chip U4 dynamically adjusts the output voltage value by adjusting the pulse duty cycle of the output signal.

[0047] The microcurrent circuit 309 includes transistors Q1, Q2, Q5, Q6, Q7, and Q9. Transistors Q1, Q2, and Q5 form channel A of microcurrent output, connected to comb teeth 105 in group A. Transistors Q6, Q7, and Q9 form channel B of microcurrent output, connected to comb teeth 106 in group B. Transistor Q1 is a PNP transistor. The emitter of transistor Q1 is connected to the input microvoltage SY-V, and the collector of transistor Q1 serves as the output terminal, connected to comb teeth 105 in group A, outputting an EMS microcurrent. The microvoltage SY-V terminal is connected to resistors R24 and R25, and then to the collector of transistor Q5. The emitter of transistor Q5 is grounded, and the base of transistor Q5 is connected to chip U4. The base of transistor Q1 is connected to the other end of resistor R24. Thus, chip U4 outputs the signal "pulse current". Transistor Q5 is turned on, allowing current to flow through resistors R24 and R25. The micro-voltage SY-V drops across resistor R24, causing the base potential of transistor Q1 to fall below its emitter potential, thus turning on transistor Q1 to output an EMS micro-current. Simultaneously, the A-channel micro-current output terminal is connected to the emitter of transistor Q6, a PNP transistor. The collector of transistor Q6 is connected to ground via parallel resistor R34 and Zener diode D1. The base of transistor Q6 is connected to the collector of the B-channel micro-current output transistor Q7. In this way, the A-channel and B-channel micro-current outputs are interlocked to control safe grounding. When the potential at the A-channel micro-current output terminal is greater than the potential of the B-channel micro-current circuit 309, transistor Q6 is turned on to discharge voltage, ensuring the electrical safety of the EMS micro-current.

[0048] Transistors Q6, Q7, and Q9 constitute the microcurrent output of circuit B. Figure 9 The settings shown are similar, so I won't go into detail here.

[0049] like Figure 3 , Figure 4 As shown, a battery 202 and a Type-C charging port 203 are provided inside the handle 200 of the massage comb. The battery 202 provides power to the various circuits and components in the drive circuit, and the Type-C charging port 203 replenishes the battery 202 with power.
