[0002] Hair clippers are common hair trimming tools at present. They mainly consist of a moving blade and a fixed blade, and the trimming of hair is achieved through the relative reciprocating motion between the two. For example, the fixed blade structure of an electric hair clipper disclosed in the patent number CN218534636U includes a blade body part and a blade tooth part. The blade body part includes a front side and a back side arranged oppositely. The blade tooth part includes a plurality of uniformly arranged blade tooth bodies at the top of the blade body part. There is a gap between two adjacent blade tooth bodies. A plurality of grooves are recessed inward on the front side of the blade body part, and the gap extends to the grooves. A first clearance groove is recessed inward on the back side of the blade body part. The first clearance groove is arranged below the blade tooth part and is not connected to the blade tooth part. However, this fixed blade structure is more suitable for human hair and less suitable for trimming animal hair, with insufficient hair intake, affecting the trimming efficiency and effect.

A blade tooth group is arranged on the blade head part. The width of the blade head part is greater than that of the blade body part. The blade tooth group includes a plurality of long blade tooth bodies and a plurality of short blade tooth bodies. The long blade tooth bodies and the short blade tooth bodies are arranged at intervals. The bottoms of the long blade tooth bodies and the short blade tooth bodies are flush. The length of the long blade tooth bodies is greater than that of the short blade tooth bodies, and the length of the long blade tooth bodies is consistent with the width of the blade head part.
[0005] In several embodiments, a plurality of first hair intake grooves are recessed downward from the upper end of the blade head part. The first hair intake grooves are arranged between adjacent long blade tooth bodies and short blade tooth bodies, and the bottom of the first hair intake grooves is in a concave arc shape.
[0006] In several embodiments, a second hair intake groove is recessed inward on the front side of the blade head part. The second hair intake groove is communicated with the first hair intake groove, and the second hair intake groove does not penetrate the blade head part.
[0007] In several embodiments, the blade head part includes a front side and a back side arranged oppositely. One side surface is arranged on each of the two sides of the front side and the back side. The front side includes a first end surface, a second end surface, and a third end surface arranged in sequence. The second end surface is inclined inward.
[0008] In several embodiments, the back surface includes a first surface that is recessed inward and a second surface that is convex outward, and the radius of the first surface is 45-55 times the radius of the second surface.
[0009] In several embodiments, the side surface includes a first arc surface, a first straight surface, and a second arc surface arranged in sequence. The first arc surface extends to the upper end of the cutter head, and the second arc surface extends to the bottom end of the cutter head.
[0010] In several embodiments, both the long cutter tooth body and the short cutter tooth body include a tooth top surface, the tooth top surface extends downward to form a tooth body, and both sides of the tooth body incline outward to form tooth edge surfaces.
[0011] The beneficial effects of the present utility model are as follows:
[0012] Through the distribution design of long and short teeth, the present utility model can increase the hair entry volume, improve the trimming efficiency, make the hair enter more smoothly, and avoid jamming.
[0013] Through the structural design of specific surfaces of the cutter head, the present utility model can effectively fit the skin of animals, improve the service strength, and at the same time increase the hair entry volume and improve the shearing efficiency. Description of the Drawings

[0021] Embodiment 1
[0022] As Figures 1-4 shown, the hair trimming blade in this embodiment includes a blade body portion 10 and a blade head portion 20. The width of the blade head portion 20 is greater than the width of the blade body portion 10. A set of cutter teeth 30 is provided on the blade head portion 20. The set of cutter teeth 30 includes a plurality of long cutter tooth bodies 31 and a plurality of short cutter tooth bodies 32. The long cutter tooth bodies 31 and the short cutter tooth bodies 32 are arranged at intervals. The bottoms of the long cutter tooth bodies 31 and the short cutter tooth bodies 32 are flush. The length of the long cutter tooth bodies 31 is greater than the length of the short cutter tooth bodies 32, and the length of the long cutter tooth bodies 31 is the same as the width of the blade head portion 20. Among them, the height difference between the long cutter tooth bodies 31 and the short cutter tooth bodies 32 is about 0.5 mm.
[0023] Among them, a plurality of first hair guiding grooves 41 are recessed downward at the upper end of the blade head portion 20. The first hair guiding grooves 41 are arranged between adjacent long cutter tooth bodies 31 and short cutter tooth bodies 32. The bottom of the first hair guiding grooves 41 is in a concave arc shape. A second hair guiding groove 42 is recessed inward on the front side of the blade head portion 20. The second hair guiding groove 42 is communicated with the first hair guiding groove 41, and the second hair guiding groove 42 does not penetrate the blade head portion 20. Through the cooperation of the long cutter tooth bodies 31, the short cutter tooth bodies 32, the first hair guiding grooves 41 and the second hair guiding grooves 42, the hair guiding amount and the smoothness of hair guiding and discharging can be improved.
[0024] Among them, the blade head portion 20 includes a front face 21 and a back face 22 which are oppositely arranged. A side face 23 is provided on each side of the front face 21 and the back face 22. The front face 21 includes a first end face 211, a second end face 212 and a third end face 213 which are arranged in sequence. The second end face 212 is inclined inward. Thus, the third end face 213 is concave with respect to the first end face 211.
[0025] Moreover, the back surface 22 includes a first surface 221 that is recessed inward and a second surface 222 that is convex outward. The radius of the first surface 221 is 45 - 55 times the radius of the second surface 222, that is, the first surface 221 occupies most of the back surface 22, which extends from the top position to the bottom position of the cutter head 20 and is transitioned by the second surface 222 at the bottom position.
[0026] Moreover, the side surface 23 includes a first arc surface 231, a first straight surface 232, and a second arc surface 233 arranged in sequence. The first arc surface 231 extends to the upper end of the cutter head 20, and the second arc surface 233 extends to the bottom end of the cutter head 20. The overall side surface 23 is generally in an arc-shaped structure.
[0027] Moreover, both the long cutter teeth body 31 and the short cutter teeth body 32 include a tooth top surface 301. The tooth top surface 301 extends downward to form a tooth body 302. Both sides of the tooth body 302 incline outward to form a tooth edge surface 303. The tooth edge surfaces 303 are distributed in a V-shaped pattern, which is conducive to cutting hair.
[0028] Moreover, the cutter body portion 10 is generally in a U-shaped structure, and a plurality of connection holes are conventionally provided thereon, which is convenient for connection and fixation with the hair cutting appliance.
[0029] The scope of the present utility model is not limited by the embodiments described above, but is defined by the appended claims and their equivalents.
