Abstract
Description
Technical Field
[0001] The utility model relates to a reciprocating shaver, in particular to a reciprocating shaver cutter head. Background Art
[0002] Due to the continuous improvement of people's living standards, as people's quality requirements for daily necessities are getting higher and higher, a reciprocating shaver is required to provide a better skin feeling. For a reciprocating shaver, a mesh-type stationary cutter with holes is more suitable for short beards, and a flat-type stationary cutter with an open inlet for beards is good at shaving long curly hairs, so it is often used as a side cutter unit. Since the stationary cutter directly contacts the skin, the grooves or sharp parts are easy to cut the skin, which has a safety hazard risk, so it brings difficulties to installation and assembly. The connection between the stationary cutter and the housing is relatively rigid, and the reciprocating movement of the moving cutter brings certain vibrations to the stationary cutter, affecting the skin feeling and the service life of the stationary cutter. Seriously, it may even damage the fixed connection relationship of the stationary cutter on the housing. Summary of the Invention
[0003] The utility model provides a reciprocating shaver cutter head with safety and a flat stationary cutter.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions: A reciprocating shaver cutter head includes a housing, a moving cutter assembly and a stationary cutter assembly installed in the housing. The moving cutter assembly moves relative to the stationary cutter assembly under the drive of a driving member to achieve shaving. The stationary cutter assembly includes a stationary cutter and a stationary cutter holder fixedly connected to the lower part of the stationary cutter. The stationary cutter holder includes a middle main body frame and two elastic buffer arms respectively bent left and right at the end parts of the middle main body frame. The free ends of the elastic buffer arms are limited by abutting against the inner wall of the housing.
[0005] As an improvement: The cross-section of the middle main body frame of the stationary cutter holder is generally in an inverted U shape. The cutting edges of the moving cutter of the moving cutter assembly are arranged along the reciprocating direction on the front and back sides of the middle main body frame, and the middle main body frame is non-contact with the moving cutter cutting edges.
[0006] As an improvement: The lower left and lower right parts of the front and back walls of the inverted U-shaped middle main body frame are obliquely inwardly converged, that is, the lower left and right ends of the inverted U-shaped middle main body frame are far from the elastic buffer arms.
[0007] As an improvement: The housing is provided with connecting parts integrally or separately protruding inwardly from the left and right inner walls of the housing. The upper surface of the connecting part is provided with a sinking position for limiting the stationary cutter, and a step for the free end of the elastic buffer arm to abut against is formed on the inner wall of the connecting part.
[0008] As an improvement: A convex column is formed by extending downward at the lower part of the connecting part, and a cutter head floating spring is sleeved on the convex column.
[0009] As an improvement: The free ends of the elastic buffer arms are lower in height than the upper surface of the middle main body frame.
[0010] As an improvement: the stationary tool rest is fixedly connected to the stationary knife through laser welding on the lower surface of the stationary knife by means of an intermediate main body frame.
[0011] The beneficial effects provided by the present utility model are as follows: a stationary tool rest is fixedly arranged under the stationary knife. Since elastic buffer arms are arranged at both ends of the stationary tool rest, the reciprocating impact brought by the moving knife to the stationary knife is reduced. At the same time, the limiting of the stationary knife on the housing is assisted, so that the stationary knife is limited and connected in multiple directions, and the connection is more stable. Moreover, the structural design or expansion of the stationary knife assembly can be realized through the stationary tool rest, keeping the flatness of the stationary knife. Especially when the entire tool head floats, the stationary knife is not affected, and there is no breakage on the surface of the stationary knife except for the slot for whisker entry, ensuring safety and greatly improving the skin feeling.
[0012] The present utility model will be further introduced in detail below with reference to the drawings and embodiments. Description of the Drawings

[0015] Figure 3 is Figure 1 a cross-sectional view of Detailed Embodiment
[0016] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, an embodiment of the reciprocating shaver head of the present utility model includes a housing 3, a moving blade assembly and a stationary blade assembly installed in the housing 3. The moving blade assembly moves relative to the stationary blade assembly driven by a driving member to achieve shaving. The stationary blade assembly includes a steel stationary blade 1 and a metal stationary blade holder 2 fixed under the stationary blade. The stationary blade holder 2 includes a middle main body frame 21 and two elastic buffer arms 22 bent left and right respectively at the end of the middle main body frame. The free ends of the elastic buffer arms 22 are limited by abutting against the inner wall of the housing. To ensure the flatness of the stationary blade, in this embodiment, the stationary blade holder 2 is fixedly connected to the stationary blade by laser welding on the lower surface of the stationary blade by the middle main body frame 21. The laser welding points can be evenly distributed along the reciprocating direction. The cross-section of the middle main body frame 21 of the stationary blade holder 2 in this embodiment is generally in an inverted U shape. The moving blade cutting edges of the moving blade assembly are arranged on the front and back sides of the middle main body frame 21 along the reciprocating direction, and the middle main body frame is non-contact with the moving blade cutting edges. The lower left and lower right parts of the front and back walls of the inverted U-shaped middle main body frame are obliquely inwardly converged, that is, the left and right ends of the lower part of the inverted U-shaped middle main body frame are far from the elastic buffer arms 22. The structural design of the oblique inward convergence leaves a working space for the elastic buffer arms, and the buffer and shock absorption effect is obvious. To stabilize the connection of the stationary blade and at the same time realize the floating of the shaver head and simplify the internal structure, in this embodiment, the housing is provided with a connecting part 31 integrally protruding from the left and right inner walls of the housing. The upper surface of the connecting part 31 is provided with a sinking position 32 for limiting the stationary blade. The free ends of the elastic buffer arms 22 are lower than the upper surface of the middle main body frame 21 in height. A step 33 for the free ends of the elastic buffer arms 22 to abut against is opened on the inner wall of the connecting part 31. The connecting part 31 is arranged longitudinally between the elastic buffer arms 22 and the end of the stationary blade, and the stationary blade is fully limited. A convex column 34 is formed by extending downward at the lower part of the connecting part 31. A shaver head floating spring 4 is sleeved on the convex column 34. The overall up and down floating of the shaver head is realized through the shaver head floating spring. Of course, the connecting part 31 can also be connected to the housing in a split manner according to needs.
[0017] Although the present utility model has been disclosed above with specific embodiments, it is not intended to limit the present utility model. Any person skilled in the art can still make some modifications and refinements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the scope defined in the appended claims.
