Hereinafter, embodiments according to the present invention will be described in detail with reference to fig. 1 to 5.

Example 1

The stationary blade structure of the electric hair clipper mainly comprises a blade part 100 and a blade tooth part 200, and is usually used in cooperation with an electric hair clipper for cutting hair such as hair and animal hair, and the cutting action is formed by the transverse movement of the corresponding movable blade.

As shown in fig. 1-2, in particular, the blade portion 100 includes a front surface 11 and a back surface 12 disposed opposite to each other, the back surface 12 is used as a surface for cooperating with the movable blade, and the front surface 11 has an outward arc-shaped protrusion 101, so that the blade portion is more comfortable to be used by being attached to the skin.

The cutter tooth portion 200 is composed of a plurality of cutter tooth bodies 210 uniformly arranged at the top end of the cutter body portion 100, and a hair advancing gap exists between two adjacent cutter tooth bodies 210, correspondingly, a plurality of grooves 110 are inwards recessed in the front surface 11 of the cutter body portion 100, the grooves 110 extend downwards to the arc-shaped protrusion 101 part along the same straight line from the gap position between the cutter tooth bodies 210, and substantially span the length of half of the cutter body portion 110, so that the gap and the grooves 110 are visually connected into a whole as shown in fig. 2, and the cutter body portion 110 and the cutter tooth bodies 210 are also connected into a whole, thereby the hair advancing gap length is prolonged, the hair is avoided, and the hair jam is avoided.

As shown in fig. 3-4, a first clearance groove 120 is recessed inward on the back 12 of the blade portion 100, the first clearance groove 120 is disposed below the blade portion 200 and is not communicated with the blade portion 200, the width of the first clearance groove 120 is greater than or equal to the width of the blade portion 200, the first clearance groove 120 includes a main groove body 121 and a branch groove body 122 that are communicated, the main groove body 121 substantially spans the width direction of the blade portion 100 and is in a rectangular structure, the branch groove bodies 122 are uniformly disposed on one side above the main groove body 121, the branch groove body 122 is substantially in a semicircular structure, the direction protruding toward the blade portion 210, that is, the position of the branch 122 corresponds to the position of the blade portion 210, the contact area with the blade portion is reduced by the structure of the first clearance groove 120, and the oil can be injected into the blade portion 210 for lubrication.

Four second clearance grooves 130 are symmetrically arranged below the first clearance groove 120, the two second clearance grooves 130 are in a group and are all obliquely arranged, and the second clearance grooves 130 are in a strip-shaped structure and can also play a role in reducing the contact area.

Meanwhile, the body portion 100 is further provided with three weight-reducing grooves 140, two weight-reducing grooves 140 on two sides are symmetrically arranged and are just located below the two groups of second empty-avoiding grooves 130, the two weight-reducing grooves 140 are in special-shaped shapes and play roles of attractiveness, identification and weight reduction, and one weight-reducing groove 140 in the middle is located at the middle lower position between the two groups of empty-avoiding grooves 130 and is generally in a convex structure.

As shown in fig. 1 and 5, the cutter tooth body 210 in this embodiment includes a head portion and a body portion 213 extending downward from the head portion, the head portion includes a straight edge section 211 and an arc edge section 212 connected, the straight edge section 211, i.e., a straight-sided edge, is oriented toward the back side 12, the arc edge section 212, i.e., an arc-sided edge, is oriented toward the front side 11, the skin-contacting hair-cutting effect is facilitated by the arc edge section 212, and the hair-cutting effect is enhanced by the straight edge section 211.

It should be noted that, in the present invention, the unexplained connection mode between the components can be the connection mode commonly used in the field.

The scope of the present invention is defined not by the above-described embodiments but by the appended claims and equivalents thereof.
