[0056] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0058] Wherein: the cutter head 2 can be detachably mounted on the main machine handle 1; the drive motor 3 is mounted inside the main machine handle 1, and the drive shaft 31 extends outward from the main machine handle 1 to drive the cutter head 2 to work; the power supply 4 is used to supply power to the drive motor 3; the power switch 5 is connected to the circuit of the power supply 4 supplying power to the drive motor 3; the circuit board structure 6 has a circuit for supplying different voltages to the drive motor 3; the infrared transmitter 7 is arranged on the main machine handle 1 and can emit infrared rays; the reflective groove 8 is arranged on the cutter head 2, opposite to the infrared transmitter 7, and is used to reflect infrared light line; the infrared receiver 9 is arranged on the host handle 1, and can receive the infrared rays reflected back by the reflective groove 8; the bottom reflective surface of the reflective groove 8 arranged on different types of the cutter heads 2 is at different distances from the infrared transmitter 7 and / or the infrared receiver 9, and the infrared receiver 9 sends out different indication signals according to the strength of the received infrared rays; the chip 61 is arranged on the circuit board structure 6, and after receiving different indication signals emitted by the infrared receiver 9, the circuit board structure 6 is controlled to connect different circuits to supply the corresponding cutter heads 2 with corresponding voltages.

[0059] In the multifunctional shaver of the present embodiment, which can automatically adapt the power supply voltage according to the cutter head, the bottom reflective surface of the reflective groove 8 arranged on different types of cutter heads 2 has different distances from the infrared transmitter 7 and / or the infrared receiver 9. Since infrared rays are obviously attenuated with the increase of propagation distance, the bottom reflective surface of the reflective groove 8 arranged on different types of cutter heads 2 is designed to be at different distances from the infrared transmitter 7 and / or the infrared receiver 9, so that the propagation distances received by the infrared receiver 9 after reflection from the bottom surface of the reflective groove 8 starting from the infrared transmitter 7 are different, and then the signals received by the infrared receiver 9 are also different, so as to identify the type of the cutter head 2 and further transmit the signal to the chip 61. The chip 61 controls the circuit board structure 6 to connect different circuits. When the power switch 5 is started, the power supply 4 can provide the current type of cutter head 2 with a power supply voltage adapted to it through the circuit.

[0060] The cutter head 2 is detachably mounted on the host handle 1 via a mounting cover 20 , and the reflective groove 8 is arranged at the inner bottom of the mounting cover 20 .

[0061] In this embodiment, the reflective groove 8 is arranged at substantially the same position inside the mounting cover 20, but at different depths. The infrared transmitter 7 and the infrared receiver 9 are both arranged at the end of the host handle 1, and are opposite to the reflective groove 8 up and down.

[0062] like Figure 9-10As shown, a head magnet 11 is provided at the end of the host handle 1, and a tool head magnet 24 is provided at the corresponding position of the tool head 2. When the tool head 2 is installed on the host handle 1, the head magnet 11 and the tool head magnet 24 attract each other, thereby accurately controlling the distance between the reflective groove 8 and the infrared transmitter 7 and the infrared receiver 9.

[0063] Specifically, the head magnet 11 is annular and fixedly disposed at the end of the host handle 1 .

[0064] like Figure 3 and Figure 8 As shown, it also includes a limiting structure, which is arranged between the host handle 1 and the mounting cover 20; the limiting structure includes: a first limiting groove 12 and / or a first limiting ridge 13, which are integrally formed on the side wall of the end of the host handle 1; a second limiting ridge 201 and / or a second limiting groove 202, which are integrally formed on the inner wall of the mounting cover 20; the first limiting groove 12 can be matched and plugged with the second limiting ridge 201, and the first limiting ridge 13 can be matched and plugged with the second limiting groove 202.

[0065] like Figure 11-13 As shown, the cutter head 2 includes three types of cutter heads, namely, a razor head 21, a U-shaped cutter head 22 and a nose hair cutter head 23; the razor head 21 is suitable for trimming facial beard, the U-shaped cutter head 22 is suitable for trimming hair, and the nose hair cutter head 23 is suitable for trimming nose hair.

[0066] The sum of the distances between the reflective bottom surface of the reflective groove 8 arranged on the shaver head 21 and the infrared transmitter 7 and the infrared receiver 9 is a first distance. After receiving the infrared ray, the infrared receiver 9 sends a first signal to the chip 61. The chip 61 controls the circuit board structure 6 to output a circuit capable of supplying a first voltage to the shaver head 21. In this embodiment, the numerical range of the first voltage is 3.4V-3.6V.

[0067] The sum of the distances between the reflective bottom surface of the reflective groove 8 arranged on the U-shaped blade head 22 and the infrared transmitter 7 and the infrared receiver 9 is the second distance. After receiving the infrared ray, the infrared receiver 9 sends a second signal to the chip 61. The chip 61 controls the circuit board structure 6 to output a circuit capable of supplying a second voltage to the U-shaped blade head 22. In this embodiment, the numerical range of the second voltage is 3.2V-3.4V.

[0068] The sum of the distances between the reflective bottom surface of the reflective groove 8 arranged on the nose hair cutter head 23 and the infrared transmitter 7 and the infrared receiver 9 is a third distance. After receiving the infrared ray, the infrared receiver 9 sends a third signal to the chip 61. The chip 61 controls the circuit board structure 6 to output a circuit capable of supplying a third voltage to the nose hair cutter head 23. In this embodiment, the value range of the third voltage is 3.0V-3.2V.

[0069] like Figure 1 As shown, on the front of the host handle 1, above the power switch 5, there are also indicator lights, which are, from top to bottom, a U-shaped U-blade indicator light, a razor indicator light with lines in a box, a diamond-shaped nose hair cutter indicator light, and a charging indicator light with a battery symbol. When the U-shaped cutter head is installed on the host handle 1, the U-blade indicator light is on, and the shaving indicator light, the nose hair indicator light, and the charging indicator light are off; when other cutter heads are replaced, the indicator light indicating this type of cutter head is on, and the other lights are off; the charging indicator light is only on when charging.

[0070] The method of using the multifunctional shaver capable of automatically adapting the power supply voltage according to the cutter head in this embodiment is as follows:

[0071] First, according to the user's usage requirements, for example, the shaver head 21 is installed on the main unit handle 1. At this time, the infrared ray emitted by the infrared transmitter 7 is directed to the reflective groove 8, and is received by the infrared receiver 9 after being reflected by the reflective groove 8. The infrared receiver 9 determines that the type of the currently installed head is a shaver head based on the information of the received infrared ray, and then sends a signal to the chip 61 installed on the circuit board structure 6. After receiving the signal, the chip 61 controls the circuit board structure 6 to connect the circuit that can supply the first voltage to the shaver head 21, and at this time, the mark on the main unit handle 1 for identifying the shaver head 21 lights up; when the power switch 5 is pressed, the power switch 5 controls the power supply 4 to supply the first voltage to the shaver head 21; the working processes of the remaining heads are similar.

[0072] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
