[0034] As Figures 1 to 10 shown, a massage comb with automatic identification of liquid discharge provided in this embodiment includes:

[0035] A massage comb body, the massage comb body includes a handle portion 1 and a massage portion 2 integrally connected to the handle portion 1. The handle portion 1 is provided with a main circuit board 11. One end face of the massage portion 2 is provided with massage comb teeth 21 for massage, and the massage portion 2 is provided with an installation cavity 22;

[0036] A liquid storage bin 3, the liquid storage bin 3 is detachably installed in the installation cavity 22. The liquid storage bin 3 is provided with a liquid storage cavity 31 and a liquid filling port 32 communicated with the liquid storage cavity 31. An electric connection contact 33 is arranged on the outer surface of the liquid storage bin 3. A partition cavity is arranged inside the liquid storage bin 3 and a peristaltic pump 34 is installed in the partition cavity. The water inlet pipe of the peristaltic pump 34 is communicated with the liquid storage cavity 31. The lower end of the liquid storage bin 3 is provided with a liquid outlet comb tooth 35. The top end of the liquid outlet comb tooth 35 is provided with a liquid outlet and is placed at the massage comb tooth 21. The water outlet pipe of the peristaltic pump 34 is communicated with the liquid outlet comb tooth 35. The electric connection contact 33 is electrically connected with the peristaltic pump 34;

[0037] An identification mechanism 4, the identification mechanism 4 is installed on the massage part 2 and an induction comb tooth 41 is arranged on the same end face of the liquid outlet comb tooth 35 and the massage comb tooth 21. The identification mechanism 4 is provided with a secondary circuit board 42 and a conductive thimble 43. The induction comb tooth 41 is made of a conductive material. The induction comb tooth 41, the conductive thimble 43 and the main circuit board 11 are all electrically connected with the secondary circuit board 42. The top end of the conductive thimble 43 is exposed outside the installation cavity 22;

[0038] Wherein, after the liquid storage bin 3 is installed in the installation cavity 22, the conductive thimble 43 forms a top contact with the electric connection contact 33. The main circuit board 11 or the secondary circuit board 42 is provided with an EMS skin detection circuit. The EMS skin detection circuit is electrically connected with the induction comb tooth 41 through circuit board traces.

[0039] In this embodiment, an identification mechanism 4 is mainly established on the original massage comb. The induction comb tooth 41 on the identification mechanism 4 is used to detect the human body current to determine whether it contacts the human skin, so as to provide a trigger condition for subsequent automatic liquid discharge control; at the same time, the liquid discharge form of the liquid storage bin 3 uses a peristaltic pump 34 as the drive, so that the essence liquid inside the liquid storage bin 3 can only be discharged outward after the peristaltic pump 34 works. Combining with the trigger condition provided by the identification mechanism 4, an automatic identification and liquid discharge function can be formed, and the use of the peristaltic pump 34 for discharge will not cause liquid leakage or seepage, and also makes the liquid storage more balanced.

[0040] The specific usage steps are as follows: First, add the corresponding essence to the liquid storage chamber 3 from the liquid filling port 32. After adding the essence, seal the liquid filling port 32 (usually sealed with a soft rubber plug). Then, align and install the liquid storage chamber 3 into the installation cavity 22. Subsequently, the massage work can be started. After the massage work is started, the user only needs to hold the handle part 1 with one hand, and make the massage comb teeth 21 of the massage part 2 lean against the scalp or other places. Since the induction comb teeth 41 and the liquid outlet comb teeth 35 are on the same side, at this time, the induction comb teeth 41 will contact the scalp. Because the human body has a natural bioelectric current, when the induction comb teeth 41 contact the human body, the bioelectric current will be transmitted to the EMS skin detection circuit through the induction comb teeth. As for the circuit structure of the EMS skin detection circuit, it can be adopted as Figure 10 shown in the appendix Figure 10 . In the figure, G_VDD is the voltage network after the boost circuit boosts the voltage, V01 and VO2 are two EMS contact networks, DG is the single-chip microcomputer skin detection and recognition point, VO_B and VO_A are two IO ports of the single-chip microcomputer control bipolar. When VO_B gives a high-level signal, Q3 conducts, making the EMS contact VO2 have a high voltage. At this time, VO1 has a low voltage, and the high voltage at VO2 and the low voltage at VO1 contact the skin to form a loop to generate an EMS current. The current flows from VO2 to VO1, and VO1 flows through Q3 conduction to the DG network and then to GND. The DG network detects the voltage to determine contact with the skin. When the circuit system has recognized contact with the skin, it will control the peristaltic pump 34 to work. After the peristaltic pump 34 works, it will first extract the essence in the liquid storage cavity 31, and then through the power of the peristaltic pump 34, discharge the essence from the liquid outlet comb teeth 35. As long as the skin is recognized, the liquid will be discharged, and there will be no uncontrollable phenomena such as random liquid discharge. In this way, the function of massaging and timely discharging the essence can be achieved. When the massage is no longer needed, only by separating the massage part from the contact with the human body, the peristaltic pump 34 will automatically stop working,

[0041] Further, to make the discharge volume of each liquid outlet comb tooth 35 more evenly controllable, a sleeve 36 is sleeved on the bottom of the liquid storage chamber 3 in this embodiment. The liquid outlet comb teeth 35 are arranged on the sleeve 36. A socket groove 37 for receiving the liquid storage cavity 31 is provided on the sleeve 36. A pressing plate 38 covers the bottom of the socket groove 37. The bottom surface of the socket groove 37 is provided with non-connected diversion grooves 371. After the pressing plate 38 is fixedly placed on the bottom of the liquid storage cavity 31, the diversion grooves 371 form non-connected diversion channels. One end of each diversion channel is respectively connected to a single liquid outlet comb tooth 35, and the other ends of all the diversion channels converge at one place. Water inlet holes 381 are provided on the pressing plate 38 at the corresponding air flow channels. A socket 39 for inserting the water outlet pipe of the peristaltic pump 34 is provided at the bottom of the liquid storage cavity 31. The bottom of the socket 39 covers all the water inlet holes 381. And a bifurcation port 391 corresponding to the number of the water inlet holes 381 is formed at the port of the socket 39 where it is docked with the diversion channel. Each bifurcation port 391 is respectively docked with a single water inlet hole 381. Through such a setting, relying on a single water outlet pipe, the discharged essence liquid can be automatically diverted and sent to the corresponding liquid outlet comb teeth 35, so that there will be no problem of a large difference in the discharge volume among different liquid outlet comb teeth 35.

[0042] Further, for the design of the induction comb teeth 41, to ensure that after the massage comb teeth 21 contact the skin, the induction comb teeth 41 can also contact the skin. Therefore, the safest solution is that the height of the induction comb teeth 41 extended by default is greater than that of the massage comb teeth 21. However, if it is higher than the massage comb teeth 21, the induction comb teeth 41 will hinder the work of the massage comb teeth 21. Therefore, in this embodiment, the induction comb teeth 51 are specially provided to be telescopic. That is, the induction comb teeth 41 include a top column 411 and a base 412 made of conductive materials. The top end of the top column 411 is a smooth surface. The bottom of the top column 411 is hidden in the inner cavity of the base 412. And a spring 413 is provided between the bottom of the top column 411 and the inner cavity of the base 412. The base 412 is fixedly installed on the secondary circuit board 42 and is electrically connected to the secondary circuit board 42. After the top column 411 first contacts the skin, relying on the setting of the spring 413, the top column 411 can be pushed, so that the subsequent massage comb teeth 21 can smoothly contact the skin.

[0043] Further, to improve the product grade and functional diversification, lamp beads 44 are provided on the secondary circuit board 42 in this embodiment. The material of the massage part 2 at the position directly opposite to the lamp beads 44 is set as a light-transmitting material. In this way, there can be a lighting effect during massage. When necessary, corresponding effects can also be designed according to different light wave frequency bands of the set lights, which is specifically determined according to actual needs.

[0044] Further, the liquid storage chamber 3 of this embodiment is a detachable structure. Specifically, at least two clamping protrusions 301 are provided on the side surface of the liquid storage chamber 3, and clamping grooves 302 corresponding to the clamping protrusions 301 are provided at the opening of the installation cavity 22. The clamping grooves 302 are in an "L" shape. The clamping protrusions 301 are provided with arc-shaped protrusions 303. Correspondingly, arc-shaped grooves 304 are provided in the clamping grooves 302. In this way, it can not only meet the requirements of detachable installation of the liquid storage chamber, but also ensure more stable assembly after assembly, and can also ensure that the conductive thimble and the power connection contact can form a top contact after assembly is completed.

[0045] Further, to better facilitate the user to install or remove the liquid storage chamber and prevent the user's fingers from slipping, the top end of the liquid storage chamber 3 of this embodiment is placed outside the massage part, and a protective corrugation 305 is provided at the top end of the liquid storage chamber 3.

[0046] Further, for the internal control system, mainly the main circuit board 11 is integrated with an MCU chip (i.e., the single-chip microcomputer mentioned above), a peristaltic pump control circuit, and a button 12. The button 12 is placed on the shell of the handle part 1. The EMS skin detection circuit, the peristaltic pump control circuit, and the button 12 are all electrically connected to the MCU chip. The MCU chip can adopt the SC8F5776 model.

[0047] Further, a rechargeable battery 13 and a charging port 14 are built in the handle part 1 of this embodiment, and the main circuit board 11 is connected to the rechargeable battery 13 and the charging port 14 respectively through a charge and discharge management circuit.

[0048] In addition, for the structure of the massage comb teeth 21 of this embodiment, it can be fixed massage comb teeth 21, or electric massage comb teeth that can swing under electric drive. Both of these forms are applicable to this embodiment.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
