Technical Field

[0001] The present invention relates to the technical field of hair trimming equipment, and in particular to a multi-functional angle-adjustable hair clipper for bald heads. Background Art

[0002] With the increasing emphasis on personal image and hygiene management, hair clippers, as tools for shaving hair, have been widely used. Traditional hair clippers mainly consist of a motor, a razor head, a housing, and a power supply. Their working principle is to drive the razor head to rotate at high speed or reciprocate through the motor, thereby achieving the shaving of hair.

[0003] In currently common hair clippers on the market, the angle of the razor head is usually fixed. Although this design can meet the basic hair shaving needs to a certain extent, there are some obvious limitations in actual use. For example, when users need to shave hair in different parts, due to the fixed angle of the razor head, the shaving effect may not be ideal. Especially when shaving hair in areas such as the neck and hairline, it is easy to have the situation of incomplete shaving or skin injury. In addition, for users with different head shapes and hair qualities, the fixed-angle razor head is difficult to adapt to diverse shaving needs, reducing the user experience.

[0004] Due to the fixed angle of the razor head, it cannot be adjusted according to different shaving parts and angles, resulting in an unsatisfactory shaving effect and prone to incomplete shaving or skin injury;

[0005] The fixed-angle razor head is difficult to meet the needs of users with different head shapes and hair qualities, reducing the versatility and applicability of the product;

[0095] Furthermore, the rotating connection mechanism includes a first connection portion 5 provided on the driving device 2, and a second connection portion 6 provided on the inner wall of the receiving portion 4 and rotatably connected to the first connection portion 5; an angle locking mechanism is also provided at the connection between the driving device 2 and the main body 1.

[0096] Furthermore, the angle locking mechanism includes a toothed groove disk 15 fixedly provided in the housing 201, and a fixed tooth disk 16 elastically connected to one end of the second connection portion 6 connected to the first connection portion 5 and meshing with the toothed groove disk 15.

[0097] Further, a button 13 is installed on the body 1. One end of the button 13 protrudes with a fixing post 14 that penetrates the outer wall of the body 1 and the second connecting portion 6. The fixing post 14 penetrates the fixing gear disk 16, and the outer wall of the fixing post 14 engages with the fixing gear disk 16. One end of the fixing post 14 penetrates and engages with the second connecting portion 6 on the other side.

[0098] In this embodiment, by installing the button 13 on the body 1, the button 13 uses the fixing post 14 penetrating in the second connecting portion 6 to push the fixing gear disk 16 located in the housing 201, so that it can move in the housing 201. When the button 13 is pressed, the fixing post 14 pushes the fixing gear disk 16, and pushes the fixing gear disk 16 that was originally engaged with the tooth groove disk 15 fixedly arranged in the housing 201, so that it disengages from the tooth groove disk 15. When the fixing gear disk 16 disengages from the tooth groove disk 15, the housing 201 is in an active state on the body 1, and the angle of the housing 201 can be adjusted, thereby adjusting the angle of the driving device 2. After adjusting the angle, the button 13 can be released, and the fixing gear disk 16 is reset by the elastic force of the spring 12 and engages with the tooth groove disk 15 to fix the housing 201.

[0099] Specifically, a through hole communicating to the outside of the housing 201 is reserved at the middle position of the tooth groove disk 15. The fixing gear disk 16 is a hollow structure, and the diameter of the hollow part of the fixing gear disk 16 is smaller than the diameter of the through hole of the tooth groove disk 15. A spring 12 is installed at the other end of the fixing gear disk 16, so that the spring 12 applies an elastic force to the fixing gear disk 16 to ensure its stable engagement with the tooth groove disk 15. The fixing post 14 is a variable-diameter structure. The part of it located in the through hole of the tooth groove disk 15 is thicker, and the part of it penetrating the hollow part of the fixing gear disk 16 is thinner. The joint of the thick and thin parts of the fixing post 14 abuts against the fixing gear disk 16 to facilitate pushing the fixing gear disk 16 to move. Among them, at least one side of the outer wall of the fixing post 14 is set as a horizontal plane, and the cross-sectional shape of the fixing post 14 matches the shape of the hollow part in the middle of the second connecting portion 6, which can prevent the situation that the housing 201 can still rotate when the fixing gear disk 16 is engaged with the tooth groove disk 15.

[0100] Further, the housing 201 includes a first housing 204 and a second housing 205. The first housing 204 and the second housing 205 are assembled together, and a connecting structure 206 is installed at the joint of the first housing 204 and the second housing 205. The first connecting portion 5 is opened on the connecting structure 206.

[0101] Further, the connecting portion 203 is a component protruding from the outer shell 201. A clamping groove 17 is formed in the connecting portion 203. The driving end of the driving motor 202 penetrates through the connecting portion 203 and is connected with a transmission member 18. One end of the cutter head 3 is provided with a mounting portion 19 engaged in the clamping groove 17;

[0102] The inner wall of the clamping groove 17 is provided with a clamping ring 20 protruding therefrom. The outer wall of the mounting portion 19 is provided with a positioning groove 21 engaged with the clamping ring 20.

[0103] By engaging the mounting portion 19 on the cutter head 3 to the connecting portion 203, the cutter head 3 can be fixed on the driving device 2, and the linkage member for driving the blade to rotate at a high speed in the cutter head 3 is engaged with the driving motor 202 to ensure the smooth transmission of power of the driving motor 202; wherein, the outer wall of the connecting portion 203 may be provided with a protrusion, and the protrusion can limit the angle at which the mounting portion 19 is mounted on the connecting portion 203, limit the rotation of the mounting portion 19, and prevent its rotation from affecting the use.

[0104] Specifically, the cutter head 3 includes a central cutter head and a plurality of movable cutter heads arranged in a surrounding manner outside the center. Both the central cutter head and the movable cutter heads are composed of an outer cutter net and inner blades rotatably connected inside the outer cutter net. Moreover, the movable cutter heads are movably connected to the central cutter head, and the movable cutter heads can swing relative to the central cutter head within a certain range, endowing the movable cutter heads with a certain degree of mobility and expanding their applicable range;

[0105] Among them, the inner blade of the central cutter head is connected to the transmission member 18 through a connecting member. The driving motor 202 drives the connecting member to rotate, thereby driving the inner blade of the central cutter head in a linkage manner. At the same time, gears or other types of linkage members for driving the inner blades of other movable cutter heads are also provided on the connecting member. The inner blades of each movable cutter head are linked with the linkage member on the connecting member through linkage members such as gears, so that the driving motor 202 can drive multiple inner blades to work simultaneously.

[0106] Further, a magnetic attraction ring 22 is embedded in the bottom wall of the clamping groove 17, and an adsorbing member 23 that mutually attracts the magnetic attraction ring 22 is further provided at the edge of the end of the mounting portion 19.

[0107] In some embodiments, a magnetic attraction ring 22 that magnetically attracts the mounting portion 19 is built into the clamping groove 17, which can further improve the stability of the mounting portion 19 in the clamping groove 17. At the same time, the positioning function of magnetic attraction can be utilized to ensure that the mounting portion 19 is correctly mounted in the clamping groove 17.
