According to an embodiment of the present invention, a blade for enhancing hair removal efficiency is used in combination with an electric hair clipper for cutting hair such as hair, and is adapted to make repeated lateral movements with a movable blade or a stationary blade, thereby forming a cutting action.

As shown in fig. 1 to 5, the blade of the present embodiment includes a blade body 100 and a blade tooth 200 provided at one end of the blade body 100, the length of the blade body is about 40mm, the thickness of the blade body is about 7mm, and the width of the entire blade is about 21 mm.

Example 1

The cutter tooth 200 comprises a tooth root 210 and a plurality of tooth parts 220 arranged on the tooth root 210, wherein each tooth part 220 is provided with a cutting surface 221 and a non-cutting surface 222 which are arranged oppositely, each cutting surface 221 comprises a top 2211 and cutter edges 2212 positioned on two sides of the top 2211, the cutter edges 2212 between every two adjacent tooth parts 220 form a cutting area 230 which is basically in an inverted herringbone shape, the tops 2211 are flat and straight, and the included angle between the tops and the cutter edges is about 100-145 degrees, so that the hair is facilitated to be sent.

Specifically, the two cutting edges 2212 positioned on the outermost side of the cutter tooth 200 extend to the tooth root 210, and more specifically, the two cutting edges 2212 positioned on the outermost side of the cutter tooth 200 extend to the joint between the tooth root 210 and the cutter body 100 along the side of the tooth root 210, that is, the two sides of the tooth root 210 are also used as cutting surfaces, and the cutting edges are positioned on the same straight line with the side positions of the tooth root and are linearly and inwardly inclined.

Specifically, the cutting surface 221 and the non-cutting surface 222 are both flat end surface structures, but both sides of the cutting surface, i.e., the blade position, extend to both sides of the non-cutting surface, taking the cutting surface as an example of an isosceles trapezoid structure, the projection surface of the non-cutting surface is located in the middle of the cutting surface, the upper bottom and the lower bottom of the non-cutting surface are parallel, but the upper bottom and the lower bottom of the cutting surface are both longer than the upper bottom and the lower bottom of the non-cutting surface, so that two inclined connecting surfaces 1000 exist between the cutting surface and the non-cutting surface, and the blade structure protrudes.

Then, an oil groove 240 is formed in the tooth root portion 210, a gap exists between the oil groove 240 and the tooth portion 220, the oil groove 240 extends along the distribution direction of the tooth portion 220 and does not penetrate through the tooth root portion 210, the upper edge and the lower edge of the oil groove are linear and parallel to the top portion 2211, oil storage is facilitated, a lubricating effect is provided during the movement of the blade, and the distance between the top portion 2211 and the upper edge of the oil groove is about 1.8 mm.

The cutter body 100 mainly includes a first connecting section 110, a second connecting section 120 and a third connecting section 130, the first connecting section 110 extends downward along the bottom edge of the tooth root 210, the second connecting section 120 extends downward along the bottom edge of the first connecting section 110, and the third connecting section 130 extends downward along the bottom edge of the second connecting section 120. The first connecting section 110 and the second connecting section 120 both have radians, the cambered surfaces of the first connecting section 110 and the second connecting section 120 face opposite directions, the third connecting section 130 is in a straight surface shape, the third connecting section 130 is parallel to the tooth root 210, the first connecting section and the second connecting section are equal in length, the first connecting section and the second connecting section are combined to form an S-shaped transitional elastic section structure, the side surface of the first connecting section is in a parabolic shape, the side surface of the second connecting section is in a semicircular shape with the radius of about 0.65mm, and two mounting holes are correspondingly formed in the third connecting section and are matched with a hair clipper for use.

Example 2

In this embodiment, unlike embodiment 1, the two blades 2212 located at the outermost side of the cutter tooth 200 specifically include a first blade 201, a second blade 202, and a third blade 203, the first blade extends linearly outward from the top of the tooth in a slant direction, and the tail is connected to the second blade 202, the tail is located at the outer side of the tooth root, the second blade 202 is arc-shaped, the arc surface faces the outer side of the tooth root, and the tail of the second blade 202 is retracted inward to the side of the tooth root, thereby extending completely to the side of the tooth root and using the side of the tooth root as a cutting surface.

It has increased the volume of sending out to a certain extent through the blade structure of two outmost sides that have the protruding changeover portion, avoids the card to send out.

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.
