Description

Technical Field

[0001] The utility model relates to the field of shavers, in particular to a shaver head fixed blade structure, a blade head structure and a shaver. Background Art

[0002] A shaver is used to clean body hair to improve personal image. For example, patent application No. 202221400467.1 discloses a shaver with a safety blade head, which includes a lower blade holder, a fixed blade, a movable blade, an upper blade holder, a torsion spring, an upper shell, a lower shell, an inner shell, a blade head motor, an eccentric shaft, a circuit board assembly, a battery, a switch button and a spring hook; the fixed blade is pressed into the lower blade holder to form a fixed blade assembly; the movable blade is connected to the upper blade holder by a buckle to form a movable blade assembly; the fixed blade includes a fixed blade body, a covering guardrail, and a mounting hole. The fixed blade body is fixedly mounted on the inner side of the lower blade holder. The mounting hole is opened on the surface of the fixed blade body and the number of mounting holes is the same as the number of mounting columns. The fixed blade is pressed into the outer side of the mounting column of the lower blade holder through the mounting hole to connect the fixed blade to the lower blade holder. The fixed blade structure of the shaver head is a guardrail structure that is directly stamped and bent on the fixed blade body. The thickness of the fixed blade body plate using the stamping and bending process cannot be too thick. The thin thickness of the fixed blade will make the blade body have poor rigidity. The poor rigidity of the blade body will cause the blade body to be easily deformed, because it is not convenient to process the teeth after bending. The teeth of the fixed blade body structure have been processed before bending. When the bending process is performed, it is also easy to cause the fixed blade body to deform. Due to the limitations of the structural processing technology, it is easy to cause the fixed blade body to deform, resulting in a high rate of product processing defects and high processing costs. The tooth position plane and the tooth position plane of the moving blade body need a certain degree of plane fit to cooperate with the blade head to achieve a good shearing effect. The deformation of the tooth position plane of the fixed blade body that is poorly processed will cause the shearing effect of the blade head to deteriorate, and the hair will not be cut or pulled, which is easy to cause harm to the user and trigger corresponding safety incidents. To this end, the present application proposes a fixed blade structure of a shaver head, a blade head structure and a shaver to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combination Figures 1 to 3 The present embodiment is described. The present embodiment provides a fixed blade structure of a shaver head, which includes a fixed blade body 11 and a guardrail structure 2. The fixed blade body 1 is embedded in the guardrail structure 2. One end of the fixed blade body 1 is provided with a blade tooth 11. One end of the guardrail structure 2 is provided with a fence 21. The shape of the fence 21 is consistent with the shape of the blade tooth 11 and is aligned with each other. The fixed blade body 11 and the guardrail structure 2 are split structures. The fixed blade body 11 adopts a sheet structure, and the guardrail structure 2 is provided with a plane structure 22. The fixed blade body 11 is attached to the plane of the guardrail structure 2. On the structure 22, the fixed blade of the sheet structure is not easy to deform during the processing, and the thickness of the blade body can be freely selected, which can well ensure the flatness and rigidity of the blade body, improve the quality of the fixed blade, and well ensure the shearing effect of the blade head. The structure can also effectively shield the moving blade 4 to prevent the sharp part of the moving blade of the blade head from contacting the skin during the use of the shaver. The tip of the blade head is a smooth arc angle formed by the surface bending. The tip of the blade head of the guardrail structure 2 will feel softer and more comfortable when in contact with the skin, which can bring a better experience to the user. The fixed blade body 1 is easier to process, the blade body has good rigidity, is not easy to deform, can better ensure the shearing effect of the blade head, and can also avoid the contact of the moving blade 4 on the shaver head with the skin during the use of the shaver to the greatest extent, greatly improving the safety factor of the use of the shaver, and bringing safer protection to consumers.

[0031] Applied to the cutter head structure, such as Figure 4-7 As shown in Figure 11, the tool head structure includes the above-mentioned fixed knife structure, lower knife holder 3, movable blade 4, upper knife holder 5 and torsion spring 6.

The movable blade 4 connected to the upper knife holder 5 is connected to the fixed knife structure in the lower knife holder 3 through the action of the torsion spring 6, and the movable blade 4 can reciprocate left and right along the fixed knife structure.

[0032] like Figure 1-3As shown in , 9, two positioning holes 7 and four mounting holes 8 are provided on the plane structure 22 of the fixed blade body 11 and the guardrail structure 2. The positioning holes 7 and the mounting holes 8 are symmetrically arranged. The inner side of the lower tool holder 3 is provided with corresponding positioning columns 31 and rivet columns 32. After the fixed blade body 11 is embedded in the guardrail structure 2, the positioning column 31 is inserted into the positioning hole 7 to position the fixed blade body 11 and the guardrail structure 2. The mounting hole 8 on the guardrail structure 2 is slightly smaller than the mounting hole 8 on the fixed blade body 11. After the two are welded together, a cup head rivet hole is formed. At the same time, the rivet column 32 is used to pass through the mounting hole 8 to fix the fixed blade body 11 and the guardrail structure 2. The rivet column 32 is a hollow structure. Pressure is applied by a hot riveting machine to expand its flange to fill the cup head of the cup head rivet hole on the fixed blade structure, so that the fixed blade structure is fixed in the lower tool holder 2.

The baffle 33 can prevent the skin from contacting with the blade of the movable blade 4, thereby avoiding possible damage to the skin caused by the blades of the movable blades 4 on both sides of the cutter head, and buckles 34 are arranged on the baffle 33, and the engaging holes 24 on the support walls 23 are buckled with the buckles 34, thereby further fixing the fixed blade structure. When disassembling the cutter head, the cutter head can be broken off by pinching the fence 21, thereby avoiding contact with the movable blade 4 during the disassembly process of the cutter head.

[0034] like Figure 9-12 As shown, a guide groove 35 is further provided on the inner side of the lower tool holder 3 , and a guide block 53 is provided on the upper tool holder 5 , and the guide block 53 slides back and forth along the guide groove 35 .
