[0005] Furthermore, the driving device includes a first driving motor, which is fixedly connected to the cutting base. The first driving motor is provided with a first output shaft, one end of which extends out of the cutting base and is fixedly connected to the first housing.

[0006] Furthermore, a first circuit board is fixed inside the first housing, and an annular conductive ring is provided on the first circuit board. A power receiving shell is fixed outside the first drive motor. The power receiving shell is fixedly connected to the cutting base. A conductive post is provided on the power receiving shell, and the conductive post abuts against the annular conductive ring.

[0007] Furthermore, an output gear is fixed at the other end of the first output shaft, a transmission hole is provided on the cutting base, a transition gear is rotatably connected in the transmission hole, the output gear meshes with the transition gear, and a connecting column is eccentrically provided on the transition gear.

[0008] Furthermore, the hair-shaving assembly includes an upper scissor blade, a lower scissor blade, and a scissor blade pressure plate. The lower scissor blade is fixed in the device cavity, the upper scissor blade is fixedly connected to the scissor blade pressure plate, the scissor blade pressure plate is slidably connected in the device cavity, and a connecting plate is hinged between the scissor blade pressure plate and the connecting post.

[0009] Furthermore, the cutting base is fitted with a rotating bearing, which is fixedly connected to the first housing.

[0028] This invention provides a hair trimmer, comprising a first housing 1 and a second housing 2 rotatably connected, see reference. Figure 1 The first housing 1 and the second housing 2 are located at one end of the whole. The first housing 1 and the second housing 2 can be opened and closed in an alligator mouth style. The first housing 1 is provided with a cutting groove 11. The cutting groove 11 is preferably located at the end away from the rotating position. A cutting base 3 is rotatably connected in the cutting groove 11. The cutting base 3 is provided with a device cavity 31. The surface of the cutting base 3 is provided with a relief groove 32 that communicates with the device cavity 31. A hair-shaving component 33 is provided in the device cavity 31. The hair-shaving component 33 extends out of the device cavity 31 through the relief groove 32. The extended part of the hair-shaving component 33 is mainly a blade, which is used to cut the split ends of the hair. Several comb teeth 34 are fixed on the cutting base 3. 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-shaving component 33 to cut.

[0029] The operating principle of this solution is as follows: After clamping the hair with the first housing 1 and the second housing 2, the hair is continuously pulled down. This operation is similar to the operation of a hair straightener. At the same time, the cutting base 3 in the first housing 1 rotates continuously. The comb teeth 34 on the cutting base 3 comb and loosen the hair, causing the ends of the hair that enter between the first housing 1 and the second housing 2 to lift up from the main body of the hair. The hair trimming component 33 on the cutting base 3 then trims the lifted ends. Healthy long hair shafts are clamped by the first housing 1 and the second housing 2 and will not lift up until the ends of the long hair shafts enter. Because there is a certain distance between the rotating hair trimming component 33 and the clamped main body of the hair, the accidental cutting of long hair shafts is avoided, ensuring that the hair trimming component 33 only trims the ends of the hair. Users only need to clamp the hair with the first housing 1 and the second housing 2 and pull it down to complete the trimming of the ends of the hair, making the operation more convenient.

[0030] like Figure 3 , 4As shown, the driving device 35 includes a first driving motor 351, which is fixedly connected to the cutting base 3. The first driving motor 351 has a first output shaft 352, one end of which extends out of the cutting base 3 and is fixedly connected to the first housing 1. Overall, the first output shaft 352 and the first housing 1 remain relatively fixed. When energized, the first driving motor 351 rotates around the first output shaft 352, maintaining a fixed connection between the first driving motor 351 and the cutting base 3, thereby achieving the rotation effect of the cutting base 3 relative to the first housing 1.

[0031] In this design, the first drive motor 351 rotates continuously. To supply power to the motor during rotation, a first circuit board 12 is fixed inside the first housing 1. The first circuit board 12 is provided with an annular conductive ring 121. A power receiving shell is fixed outside the first drive motor 351. The power receiving shell is fixedly connected to the cutting base 3. The power receiving shell is provided with a conductive post 353. The conductive post 353 abuts against the annular conductive ring 121. Power is supplied to the first drive motor 351 through the conductive post 353 and the power receiving shell.

[0032] like Figure 4 As shown, an output gear 354 is fixed at the other end of the first output shaft 352. A transmission hole 36 is provided on the cutting base 3. A transition gear 361 is rotatably connected in the transmission hole 36. The output gear 354 meshes with the transition gear 361. A connecting post 362 is eccentrically provided on the transition gear 361. The eccentric movement of the connecting post 362 provides the driving force for the reciprocating motion of the hair-cutting assembly 33.

[0033] like Figure 4 As shown, the hair-shaving assembly 33 includes an upper scissor blade 331, a lower scissor blade 332, and a scissor blade pressure plate 333. The lower scissor blade 332 is fixed in the device cavity 31. The upper scissor blade 331 is fixedly connected to the scissor blade pressure plate 333. A connecting plate 334 is hinged between the scissor blade pressure plate 333 and the connecting post 362. The scissor blade pressure plate 333 slides in the device cavity 31. The scissor blade pressure plate 333 reciprocates under the drive of the connecting plate 334, and drives the upper scissor blade 331 to move synchronously. The cutting effect on the hair ends is achieved through the alternation of the upper and lower scissor blades 332.

[0034] like Figure 1As shown, the cutting base 3 is fitted with a rotating bearing 4, and the inner ring of the cutting base 3 and the rotating bearing 4 are fixed. The rotating bearing 4 is fixedly connected to the first housing 1. The rotating bearing 4 enables the cutting base 3 to rotate. One end of the cutting base 3 is provided with a rotating boss 37, and the side wall of the cutting groove 11 is provided with a rotating positioning groove 111. The rotating boss 37 is rotatably connected in the rotating positioning groove 111, and the rotating boss 37 can ensure the rotational stability of the cutting base 3.

[0035] To facilitate the collection of hair clippings generated during cutting, the first housing 1 is provided with an opening 13, which is located above the cutting groove 11. The first housing 1 is provided with a detachable transparent cover 14, which is used to close the opening 13. Hair clippings enter the transparent cover 14 under the action of the continuously rotating comb teeth 34 and the hair-cutting component 33, and are retained in the transparent cover 14 under the action of centrifugal force and the wind force generated by the rotation of various components on the cutting base 3, which facilitates subsequent cleaning.

[0036] Considering that the operating speed of the hair-cutting component 33 is significantly higher than the rotation speed of the cutting base 3, and both are powered by the first drive motor, see [reference needed]. Figure 5 To meet the different speed requirements of the two, a reducer 355 is fixed at one end of the first drive motor 351, and one end of the first output shaft 352 is connected to the reducer 355. A second output shaft 356 is provided on the reducer 355. The second output shaft 356 is fixedly connected to the first housing 1. The second output shaft 356 serves as the rotation initiation point of the cutting base 3, meeting the operation requirements of the cutting base 3 with a lower rotation speed.

[0037] like Figure 3 As shown, the clearance grooves 32 are in groups of one or more, and an installation plane is provided between adjacent clearance grooves 32. The comb teeth 34 are fixed on the installation plane. The increase of clearance grooves 32 also realizes the increase of the processing station for cutting on the cutting base 3, thereby improving the cutting efficiency of this product on hair ends.

[0038] The first housing 1 is also provided with a second circuit board 15, a button 16 and a power supply 17 that are electrically connected to the drive device 35. The button 16 is connected to the second circuit board 15 and is used to control whether the whole machine is powered on or off. The power supply 17 provides energy for the operation of the whole machine.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
