[0002] At first, shavers were mainly used for shaving, and only facial beards were shaved, but not other body hairs. The functions were relatively simple. With the change of people's living habits, simple beard shaving can no longer meet the diverse needs of users. Therefore, multifunctional shavers have appeared on the market, which generally include shaver heads, nose hair shaving heads, and body hair shaving heads. Users can install different heads according to different needs to meet different needs.

[0055] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0056] This embodiment provides a multifunctional shaver capable of automatically adjusting the power supply voltage. Figure 1-10 As shown, it includes: a host handle 1, a cutter head 2, a driving motor 3, a power supply 4, a power switch 5, a circuit board structure 6, a first chip 7 and a second chip 8.

[0057] Among them: the cutter head 2 can be detachably installed on the host handle 1; the drive motor 3 is installed inside the host handle 1, and the drive shaft 31 extends outward from the host 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 first chip 7 is arranged on the host handle 1 and can control the circuit board structure 6; the second chip 8 is arranged on the cutter head 2, and the second chip 8 arranged on different types of the cutter heads 2 is different; after different types of the cutter heads 2 are installed on the host handle 1, the first chip 7 and the second chip 8 contact or sense to identify the type of the installed cutter head 2, and the first chip 7 controls the circuit board structure 6 to connect the circuit to supply the corresponding type of the cutter head 2 with an adaptive voltage.

[0058] When different types of cutter heads 2 are installed on the main handle 1, the first chip 7 and the second chip 8 contact or sense each other to identify the type of the installed cutter head 2, and then the first chip 7 controls the circuit board structure 6 to connect the circuit that supplies the corresponding type of cutter head 2 with an adaptive voltage; that is, the multifunctional shaver of this embodiment, by respectively arranging the first chip 7 and the second chip 8 on the main handle 1 and the cutter head 2, when the cutter head 2 is installed on the main handle 1, the first chip 7 can identify the information about the cutter head type carried on the second chip 8, thereby identifying the type of the cutter head currently installed, and controlling the circuit board structure 6 to connect the circuit that supplies the power supply voltage that is adapted to the type of the cutter head currently installed.

[0059] Specifically, the first chip 7 is provided with an identifier, and the second chip 8 is burned with a code of a corresponding type of blade head. After the first chip 7 and the second chip 8 are in contact or mutually sensed, the first chip 7 recognizes the code of the second chip 8 through the identifier, and then recognizes the type of the blade head 2 corresponding to the second chip 8. Regarding the structure of the first chip 7 and the second chip 8, the existing common chip structure can be used, and burning the code into the second chip 8 is also a conventional technology. Recognizing the code burned on the second chip 8 by the identifier also belongs to the existing technology.

[0060] The blade head 2 is detachably mounted on the host handle 1 through a mounting cover 21, and the second chip 8 is arranged on the bottom surface of the mounting cover 21 facing the host handle 1 (such as Fig.10 as shown).

[0061] like Fig. 9 As shown, the first chip 7 is arranged at the end of the host handle 1 and extends upward to a certain height; when the cutter head 2 is installed on the host handle 1, the first chip 7 is in contact with and connected to the second chip 8, or can be sensed and identified.

[0062] like Figure 3 and Fig.10 As shown, it also includes a limiting structure, which is arranged between the host handle 1 and the mounting cover 21; the limiting structure includes: a first limiting groove 11 and / or a first limiting ridge 12, which are integrally formed on the side wall of the end of the host handle 1; a second limiting ridge 210 and / or a second limiting groove 211, which are integrally formed on the inner wall of the mounting cover 21; the first limiting groove 11 can be matched and plugged with the second limiting ridge 210, and the first limiting ridge 12 can be matched and plugged with the second limiting groove 211.

[0063] like Figure 7-8 As shown, a head magnet 13 is provided at the end of the host handle 1, and a tool head magnet 25 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 13 and the tool head magnet 25 attract each other, thereby accurately controlling the distance between the first chip 7 and the second chip 8.

[0064] Preferably, the head magnet 13 is annular and fixedly disposed at the end of the host handle 1 .

[0065] like Figure 11-13 As shown, the cutter head 2 includes at least one of the three types of cutter heads: a razor head 22, a U-shaped cutter head 23 and a nose hair cutter head 24; the razor head 22 is suitable for trimming facial beard, the U-shaped cutter head 23 is suitable for trimming hair, and the nose hair cutter head 24 is suitable for trimming nose hair.

[0066] The second chip 8 arranged on the razor head 22 is burned with a first code. After the first chip 7 recognizes the first code, it determines that the head installed on the second chip 8 is the razor head 22, and controls the circuit board structure 6 to connect the circuit that supplies the first voltage to the razor head 22. The value range of the first voltage is 3.4V-3.6V.

[0067] The second chip 8 arranged on the U-shaped blade head 23 is burned with a second code. After the first chip 7 recognizes the second code, it is determined that the blade head installed by the second chip 8 is the U-shaped blade head 23, and the circuit board structure 6 is controlled to connect the circuit to supply the second voltage to the U-shaped blade head 23. The value range of the second voltage is 3.2V-3.4V.

[0068] The second chip 8 arranged on the nose hair cutter head 24 is burned with a third code. After the first chip 7 recognizes the third code, it determines that the cutter head installed by the second chip 8 is the nose hair cutter head 24, and controls the circuit board structure 6 to connect the circuit that supplies the third voltage to the nose hair cutter head 24. The numerical range of the third voltage is 3.0V-3.2V.

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 adjusting the power supply voltage in this embodiment is as follows:

[0071] First, according to the user's needs, the cutter head 2 is installed on the host handle 1. The first chip 7 installed on the handle 1 contacts or senses the second chip 8 installed on the cutter head 2. The first chip 7 recognizes the code on the second chip 8, and then identifies the type of the currently installed cutter head. The signal is then transmitted to the circuit board structure 6. The circuit board structure 6 is connected to the circuit that supplies the corresponding type of cutter head 2 with a corresponding voltage. At this time, the indicator light on the host handle 1 for identifying the type of cutter head is lit; when the power switch 5 is pressed, the power opening 5 controls the power supply 4 to supply the cutter head 2 with a corresponding voltage.

[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.
