[0028] The utility model provides a hair trimmer, comprising a first housing 1 and a second housing 2 which are rotatably connected. Figure 1 The rotation position of the first shell 1 and the second shell 2 is located at one end of the whole, and the first shell 1 and the second shell 2 can be opened and closed in an alligator mouth style. A cutting notch 11 is provided in the first shell 1, and the cutting notch 11 is preferably located at one end away from the rotation position. A cutting base 3 is rotatably connected in the cutting notch 11, and an equipment cavity 31 is provided in the cutting base 3. A clearance groove 32 connected to the equipment cavity 31 is provided on the surface of the cutting base 3, and a hair cutting component 33 is provided in the equipment cavity 31. The hair cutting component 33 partially extends out of the equipment cavity 31 through the clearance groove 32. The part of the hair cutting component 33 that extends out is mainly a blade, which is used to cut the split ends of the hair. A plurality of comb teeth 34 are fixed on the cutting base 3, and a driving device 35 is provided in the cutting base 3. The driving device 35 is used to drive the cutting base 3 to rotate and the hair cutting component 33 to cut.

[0029] The use principle of this scheme is as follows: the first shell 1 and the second shell 2 clamp the hair and then continue to pull it down. The operation of this step can refer to the straight hair operation of the electric heating clamp. At the same time, the cutting base 3 in the first shell 1 rotates continuously, and the comb teeth 34 on the cutting base 3 comb and scatter the hair, so that the hair ends entering between the first shell 1 and the second shell 2 are lifted from the main body of the hair, and then the lifted hair ends are trimmed by the hair cutting assembly 33 on the cutting base 3. The healthy long hair rod is clamped by the first shell 1 and the second shell 2 and will not lift up until the hair ends of the long hair rod enter. Since there is a certain distance between the rotating hair cutting assembly 33 and the clamped hair main body, the long hair rod is avoided from being cut by mistake, and the hair cutting assembly 33 is ensured to have a trimming effect only on the hair ends. The user only needs to clamp the hair with the first shell 1 and the second shell 2 and pull it down to complete the trimming of the hair ends, and the operation is also more convenient.

As a whole, the first output shaft 352 and the first shell 1 remain relatively fixed, and after power is turned on, the first driving motor 351 rotates around the first output shaft 352, and the first driving motor 351 remains fixedly connected to the cutting base 3, thereby achieving the rotation effect of the cutting base 3 relative to the first shell 1.

[0031] In this solution, the first drive motor 351 rotates continuously. In order to power the motor during the rotation process, a first circuit board 12 is fixed inside the first shell 1, and an annular conductive ring 121 is provided on the first circuit board 12. A power connection shell is fixed outside the first drive motor 351, and the power connection shell is fixedly connected to the cutting base 3.

A connecting plate 334 is hinged between the scissor blade pressing plate 333 and the connecting column 362. The scissor blade pressing plate 333 slides in the equipment cavity 31. The scissor blade pressing plate 333 moves back and forth under the drive of the connecting plate 334, and drives the upper scissor blade 331 to move synchronously, and the cutting effect on the hair ends is achieved by the interlacing between the upper and lower scissor blades 332.

[0034] like Figure 1As shown, the outer sleeve of the cutting base 3 is provided with a rotating bearing 4, the cutting base 3 and the inner ring of the rotating bearing 4 are kept fixed, the rotating bearing 4 is fixedly connected to the first shell 1, and the rotation effect of the cutting base 3 is realized by the rotating bearing 4.

[0036] Considering that the operating speed of the hair cutting assembly 33 is significantly higher than the rotation speed of the cutting base 3, and the power of both comes from the first driving motor, Figure 5 In order to meet the different speed requirements of the two, a reducer 355 is fixed at one end of the first driving motor 351, one end of the first output shaft 352 is connected to the reducer 355, and a second output shaft 356 is provided on the reducer 355. The second output shaft 356 is fixedly connected to the first shell 1, and the second output shaft 356 serves as the rotation starting point of the cutting base 3 to meet the operation requirements of the cutting base 3 with a lower rotation speed.

[0037] like Figure 3 As shown, the give way grooves 32 are more than one group, and a mounting plane is provided between adjacent give way grooves 32. The comb teeth 34 are fixed on the mounting plane. The increase of the give way grooves 32 also increases the processing stations for cutting on the cutting base 3, thereby improving the cutting efficiency of the product on the hair ends.
