Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a blade 11 according to the present embodiment. Fig. 2 is a schematic front view of the blade 11 according to this embodiment. Fig. 3 is a schematic sectional view taken along line a-a of fig. 2.

Referring to fig. 1 and 2, the blade 11 provided herein will now be described. The blade 11 includes a body 111, one end of the body 111 has a cutting face 112, and one side of the cutting face 112 has a blade edge 113 for cutting. The body 111 has a groove 114 formed on a side surface thereof, the groove 114 is located on a side of the body 111 where the blade 113 is disposed, and the groove 114 is adapted to guide hairs to a direction of the other end of the body 111. Referring to fig. 5, the other end of the body 111 is used to connect with the cutter 12 to fix the blade 11 on the cutter 12. The grooves 114 are adapted to guide hairs to the other end of the body 111, i.e. after the hair is cut by the cutting edge 113, the cut hairs can be guided to the cutter head 12 through the grooves 114 for discharge, ensuring the shaving efficiency of the blades 11. The end of the recess 114 near the cutting surface 112 has a concave surface 1141, and the concave surface 1141 intersects the cutting surface 112 at the cutting edge 113, so that the recess 114 extends to the cutting edge 113, thereby making the cutting edge 113 sharper and improving shaving efficiency. This blade 11 through set up cutting face 112 and cutting edge 113 on body 111 to guarantee the structural strength of blade 11, set up recess 114 on body 111, with the guide hair, the hair of convenient cutting is discharged, guarantees cutting efficiency, and can avoid having clean dead angle on the blade 11, convenient washing.

In one embodiment, the groove 114 may be an arc-shaped groove to smoothly guide the hair to the other end of the body 111. Of course, in some embodiments, the groove 114 may also be a curved groove with a smooth inner surface. In still other embodiments, the groove 114 may be a V-groove with a smooth bottom.

In one embodiment, the cutting edge 113 has a curved section 1131, and the curved section 1131 is curved in a manner that the middle portion is recessed toward the other side of the cutting surface 112, i.e., the middle portion of the curved section 1131 is recessed inward. When the structure is used for cutting hair, the hair can be guided to the middle position of the blade 113, so that the hair can be cut off better, and the shaving efficiency is improved; and can gather the cut hairs to be better guided to the cutter head 12, so as to discharge the cut hairs. In one embodiment, the curved section 1131 may have a parabolic shape, which may allow the hairs to be better gathered and cut. In other embodiments, the curved section 1131 can be configured in other shapes, such as an arc shape, a V shape, and the like.

In one embodiment, referring to fig. 1-3, the inner recessed surface 1141 defines an inner recess 1142, the inner recess 1142 has an inner support surface 1143, the inner support surface 1143 is located at an end of the inner recess 1142 adjacent to the cutting surface 112, and the inner support surface 1143 intersects the cutting surface 112 at the curved section 1131. The provision of the inner groove 1142 such that the inner support surface 1143 of the inner groove 1142 intersects the cutting surface 112 at the curved section 1131 and the inner groove 1142 extends to the curved section 1131 makes the curved section 1131 sharper, thereby improving shaving efficiency. In addition, the inner groove 1142 is provided, and the curved section 1131 can guide the hair to the cutter head direction better after cutting the hair, so as to discharge the cut hair.

Alternatively, the thickness of the portion of the blade 113 may be increased from the end to the middle of the curved section 1131. Because the curved section 1131 folds the hairs, the middle portion of the curved section 1131 needs to cut more hairs, so that the thickness of the blade 113 portion gradually increases from the end portion to the middle portion of the curved section 1131, and the two end portions of the curved section 1131 can better cut the hairs, while the middle portion of the curved section 1131 is less prone to wear, thereby prolonging the service life of the blade 11.

In some embodiments, the cutting surface 112 may have other shapes, such as an upper convex surface with a middle portion protruding toward one end of the body 111. The cutting surface 112 may also be wavy such that debris may be removed at the valleys of the wavy shape of the cutting surface 112.

In one embodiment, the side 115 of the body 111 on the side of the blade 113 is planar, and the groove 114 is formed on the side 115 to facilitate the processing of the groove 114, and facilitate the design and manufacture of the shape of the blade 113, thereby ensuring the manufacturing accuracy of the upper blade 113 of the blade 11.

In one embodiment, the side 116 of the body 111 facing away from the cutting edge 113 is arc-shaped, and for the cutting edge 113 having the curved section 1131, the thickness of the corresponding portion of the cutting edge 113, i.e., the width of the cutting surface 112, can be ensured, so that not only the structural strength of the blade 11 can be ensured, but also the structural strength of the cutting edge 113 portion can be increased, and the wear resistance can be improved.
