The circuit structure may be adaptively adjusted with reference to the circuit structure provided in CN2016207315632, or directly borrow the circuit structure without adjustment. It is noted that CN2018213802211 also provides a similar circuit structure.

Referring to fig. 1 to 3, the head massager in the embodiment further includes retractable comb teeth 3, the housing 1 has a cavity therein, and the retractable comb teeth 3 can be extended and shortened independently relative to the housing 1, so that when a user uses the head massager, different retractable comb teeth 3 can be adjusted in a retractable manner according to the contour of the head, and the user does not easily damage the scalp and need to adjust the use angle of the head massager frequently; but also can ensure that most of the telescopic comb teeth 3 can contact the scalp to form micro-current, thereby bringing great convenience to users.

In the embodiment, the housing 1 includes an upper housing 4 and a lower housing 5 assembled from top to bottom, and the above-mentioned cavity is formed between the upper housing 4 at the top and the lower housing 5 at the bottom. The telescopic comb teeth 3 are inserted into the lower case 5, and the telescopic comb teeth 3 can be extended and shortened relative to the lower case 5, that is, the length of the telescopic comb teeth 3 exposed from the lower case 5 and the length of the telescopic comb teeth located in the cavity can be adaptively adjusted when the telescopic comb teeth 3 receive external force.

The extension and contraction of the telescopic comb teeth 3 are relatively independent. Specifically, each telescopic comb 3 can be independently telescopic under the action of external force, and the telescopic length is also independent without influencing each other. In this way, the individual telescopic comb teeth 3 can each be adapted to the shape of the head contour.

More preferably, the upper part of each telescopic comb 3 is connected with an elastic telescopic structure. The elastic telescopic structure is arranged in the shell 1, when external force acts on the telescopic comb teeth 3 to shorten (insert) the telescopic comb teeth 3 relative to the lower shell 5, the elastic telescopic structure applies elastic force towards the lower part of the lower shell 5 to the telescopic comb teeth 3, and the elastic force pushes the telescopic comb teeth 3 to abut against the skin of the head so as to be better adapted to the head; after the external force is removed, the elastic telescopic structure pushes the telescopic comb teeth 3 back to reset.

Further preferably, a plurality of telescopic holes for the telescopic comb teeth 3 to penetrate are formed in the surface of the lower shell 5, the elastic telescopic structure comprises springs 6 sleeved outside the telescopic comb teeth 3, and the springs 6 are located above the telescopic holes. The top end of each spring 6 is fixed relative to the shell 1, and the bottom end is positioned and connected with the telescopic comb teeth 3. When the telescopic comb teeth 3 are shortened relative to the lower shell 5, the bottom ends of the springs 6 are driven to move upwards, so that the springs 6 are compressed, and elastic restoring force towards the lower part is formed; the top end of the spring 6 is fixed at this time.

In the preferred embodiment, the retractable comb teeth 3 are electrically connected with the springs 6, the output end of the voltage boosting circuit 23 is electrically connected with each spring 6, and the voltage is transmitted to the retractable comb teeth 3 through the springs 6, so that the connection mode or the conductive mode is more reliable, and the connection is easier.

Furthermore, the outer wall in the middle of each telescopic comb tooth 3 is connected with a metal supporting sheet 7 through welding or other modes, the metal supporting sheet 7 is electrically connected with the telescopic comb teeth 3, and the bottom end of the spring 6 is fixedly connected with the metal supporting sheet 7. The output end of the booster circuit 23 is connected to the metal supporting sheet 7 through a wire, and the metal supporting sheet 7 conducts electricity to the spring 6 and the telescopic comb teeth 3. Generally, the metal blade 7 has a large surface area, and is more easily connected stably, and the connection is not easily detached even when external vibration or high-frequency vibration of the connection itself is applied.

Further preferably, a guide plate arranged along the horizontal direction is fixedly arranged inside the housing 1, guide holes for the telescopic comb teeth 3 to pass through are formed in the positions, corresponding to the telescopic comb teeth 3, of the guide plate, and the aperture of each guide hole is matched with the outline of each telescopic comb tooth 3. The guide holes and the guide plates are used for limiting the moving direction of the telescopic comb teeth 3, so that the telescopic comb teeth can only do up-and-down telescopic movement but cannot transversely move and cannot form an included angle with the up-and-down direction.

Specifically, the deflector includes the last deflector 8 and the lower deflector 9 that are parallel to each other, goes up the deflector 8 and the guiding hole one-to-one of lower deflector 9, and flexible broach 3 cartridge is just between two guiding holes that correspond, and just can stretch out and draw back spring 6 from top to bottom and be located between deflector 8 and the lower deflector 9, and 8 lower surfaces are connected on the top of spring 6, and the up end of deflector 9 under the metal support piece 7 butt. In addition to the use for wiring, the metal blade 7 also functions as a positioning element. Mainly, when the outline of the metal supporting sheet 7 is larger than the aperture of the guide hole of the lower guide plate 9, the telescopic comb teeth 3 cannot move further downwards to be separated from the lower object when the metal supporting sheet 7 abuts against the upper end face of the lower guide plate 9. Meanwhile, the metal supporting sheet 7 also plays a role in transferring action, namely, the elastic restoring force of the spring 6 acts on the telescopic comb teeth 3 through the metal supporting sheet 7.

Further preferably, the housing 1 is provided with a shift position button 10 and a switch button 11, and both the shift position button 10 and the switch button 11 are electrically connected to the shift position selecting circuit 21. Specifically, range button 10 corresponds to a switch in range selection circuit 21, and switch button 11 is used primarily to control the power on and off of range selection circuit 21.
