Description

Technical Field

[0001] This utility model relates to the field of electric clipper technology, and in particular to a moving blade of an electric clipper. Background Technology

[0002] Electric hair clippers are a common hair-cutting tool widely used for trimming human hair or animal fur. Their main structure typically includes a housing, a blade assembly, and a drive motor. The blade assembly consists of a fixed blade and a moving blade that work together. The fixed blade has fixed teeth, and the moving blade has moving teeth. During operation, the drive motor drives the moving blade to perform a high-speed lateral reciprocating motion relative to the fixed blade, causing the moving teeth to engage with the fixed teeth, thus achieving the hair-cutting operation.

[0003] In existing technology, the cutting edge of the moving blade is designed with a transition arc segment at the tip of the moving blade. During actual shearing operations, this structure will exert an outward pushing effect on the hair located on both sides of the tip of the moving blade. Specifically, when the moving blade reciprocates, the hair on both sides of the tip of the blade is prone to contact with the transition arc segment. The lateral component of the arc surface will push the hair away from the shearing area of ​​the fixed and moving blades. This phenomenon leads to a reduction in the actual amount of hair cut by the blade assembly and a decrease in effective shearing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a moving blade for electric clippers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A moving blade includes a main body and teeth. The teeth are disposed on one side of the main body and include a plurality of moving teeth arranged along the length direction of the main body. Each moving tooth has a first surface, and the two sides of the first surface have cutting edges. The cutting edges extend from the root of the moving tooth to the tip of the moving tooth. The cutting edges have a straight profile at least in the region adjacent to the tip of the tooth, and the profile extends to the edge of the tip of the tooth.

[0007] Furthermore, the moving cutter tooth has a second surface, which is opposite to the first surface. The moving cutter tooth has an inclined surface on the second surface. Along the extending direction of the inclined surface, the inclined surface has a first end, which is located at the tooth tip, so that the tooth tip is in the shape of an "I".

[0008] Furthermore, from the tooth root to the tooth tip, the outline of the cutting edge always extends in a straight line.

[0009] Furthermore, in the direction perpendicular to the first surface, the projection surface of the moving cutter tooth is trapezoidal.

[0010] Furthermore, the first surface is a smooth, planar surface.

[0011] Furthermore, the main body includes a base, a first bend, and a second bend. The first bend is disposed on one side of the base, the second bend is disposed on the other side of the base, and the tooth is disposed on the side of the first bend away from the base.

[0012] Furthermore, the base is provided with a plurality of mounting holes.

[0013] The beneficial effects of this utility model are as follows: The moving blade provided by this utility model sets the contour line of the cutting edge on both sides of the tooth tip of the moving blade to a straight line, replacing the arc transition section in the prior art. When the electric clipper is performing a cutting operation, the straight cutting edge on both sides of the tooth tip can effectively prevent the hair from being pushed away from the cutting area of ​​the fixed blade and the moving blade, thereby increasing the actual amount of hair cut by the blade assembly and improving the cutting efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 The illustrated moving blade includes a main body 1 and a toothed part 2. The toothed part 2 is disposed on one side of the main body 1 and includes a plurality of moving blade teeth 21 arranged along the length direction of the main body 1. The direction in which the moving blade slides relative to the fixed blade 3 (i.e. the direction of cutting hair) is defined as the length direction of the main body 1. Along the length direction of the main body 1, a tooth gap 22 for hair to enter is formed between two adjacent moving blade teeth 21.

[0020] The moving blade 21 has a first surface 211, which slides into contact with the fixed blade 31 of the fixed blade 3. In this embodiment, to improve the fit between the moving blade 21 and the fixed blade 31, the first surface 211 is a smooth plane. The two sides of the first surface 211 have cutting edges 212, which extend from the root 213 of the moving blade 21 to the tip 214 of the moving blade 21. The cutting edge 212 has a straight profile, at least in the region adjacent to the tip 214, and the profile extends to the edge of the tip 214. In this embodiment, to further improve the shearing efficiency of the blade assembly, the profile of the cutting edge 212 always extends in a straight line from the root 213 to the tip 214.

[0021] The movable blade provided by this utility model sets the outline of the cutting edge 212 on both sides of the tooth tip 214 of the movable blade tooth 21 as a straight line to replace the arc transition section in the prior art. When the electric clipper is performing a cutting operation, the straight cutting edge 212 on both sides of the tooth tip 214 can effectively prevent hair from being pushed away from the cutting area of ​​the fixed blade tooth and the movable blade tooth 21, thereby increasing the actual amount of hair cut by the blade assembly and improving the cutting efficiency.

[0022] Preferably, the moving cutter tooth 21 has a second surface 215, which is opposite to the first surface 211. The moving cutter tooth 21 has an inclined surface 216 on the second surface 215. Along the extending direction of the inclined surface 216, the inclined surface 216 has a first end 2161, which is located at the tooth tip 214, so that the tooth tip 214 is in the shape of "I". In existing technologies, moving cutter teeth 21 and cutting edges 212 are generally formed using a gear-opening machine. However, during the processing, due to wear of the gears in the gear-opening machine, a rounded transition section easily appears on both sides of the tooth tip 214 at the cutting edge 212 of the moving cutter teeth 21. In the moving cutter processing provided by this utility model, after forming the moving cutter teeth 21 and cutting edges 212 using a gear-opening machine, an inclined surface 216 is further formed on the second surface 215 of the moving cutter teeth 21 through machining. This helps to form a straight cutting edge 212 on both sides of the tooth tip 214, thus eliminating the rounded transition section that appears on both sides of the cutting edge 212 at the tooth tip 214. In addition, by setting the inclined surface 216 on the second surface 215, the tooth tip 214 is made into a "I" shape, which also helps to keep all the tooth tips 214 of the tooth part 2 in the same straight direction.

[0023] Preferably, in order to increase the amount of hair entering the cutting area of ​​the fixed blade tooth 31 and the moving blade tooth 21, the projection surface of the moving blade tooth 21 is a trapezoid with "narrow tip and wide root" in the direction perpendicular to the first surface 211.

[0024] Preferably, the main body 1 includes a base 11, a first bent portion 12, and a second bent portion 13. The first bent portion 12 is disposed on one side of the base 11, and the second bent portion 13 is disposed on the other side of the base 11. The tooth 2 is disposed on the side of the first bent portion 12 away from the base 11. The base 11 is arched relative to the first bent portion 12 and the second bent portion 13. That is, the main body 1 slides with the fixed blade 3 through the first bent portion 12 and the second bent portion 13. The arched design of the base 11 reduces the contact area between the moving blade and the fixed blade 3, which helps to reduce the frictional resistance between them and also helps to reduce the heat generated during the sliding friction process, avoiding a burning sensation for the user.

[0025] Furthermore, the base 11 is provided with a plurality of mounting holes 111, which are used to facilitate the connection of the moving blade to the moving tool holder.

[0026] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
