Description

Technical Field

[0001] The invention relates to the technical field of shavers, and in particular to a shaver and a blade structure thereof. Background Art

[0002] A shaver is a tool for shaving hair, which includes a fixed knife assembly and a movable knife assembly. The fixed knife assembly includes a fixed knife fixing frame and a fixed knife, and the movable knife assembly includes a movable knife fixing frame and a movable knife. The front ends of the movable knife and the fixed knife are both provided with tooth cutting edges. When the shaver is working, the movable knife moves horizontally relative to the fixed knife, so that the tooth cutting edge of the movable knife produces a relatively horizontal horizontal shearing effect relative to the tooth cutting edge of the fixed knife, thereby achieving hair shaving.

[0003] In order to ensure that the moving blade head performs parallel cutting movement relative to the fixed blade head, it is necessary to limit the up and down movement of the moving blade assembly and the fixed blade assembly. Existing shavers are usually limited by a pressure elastic element, so that the fixed end of the pressure elastic element is fixed on the fixed blade assembly, and the pressure end of the pressure elastic element is fixed on the moving blade assembly, thereby limiting the up and down movement of the moving blade assembly relative to the fixed blade assembly. Due to the pressurizing effect of the pressure elastic element, the rear end of the moving blade will directly contact the rear end of the fixed blade, and the moving blade and the fixed blade are both made of cutting tool materials. If the contact time is long, they are prone to sticking or sticking after washing; and because the rear end of the moving blade is in direct contact with the rear end of the fixed blade, when the shaver is working, a large friction resistance will be generated between the moving blade and the fixed blade, resulting in an increase in the driving current required for the blade head movement, and an increase in temperature rise and noise.

[0004] In summary, how to solve the problem that the rear end of the movable blade and the rear end of the fixed blade of the shaver are easily stuck together has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide a shaver and a blade structure thereof, so as to solve the problem that the rear end of the movable blade and the rear end of the fixed blade of the shaver are easily stuck together.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a blade structure of a shaver, comprising a fixed knife assembly and a movable knife assembly horizontally and laterally slidingly matched with the fixed knife assembly, the movable knife assembly is pressed onto the fixed knife assembly through a pressure elastic element, the fixed knife assembly comprises a fixed knife and a fixed knife fixing frame fixedly connected to the fixed knife, the movable knife assembly comprises a movable knife and a movable knife fixing frame moving synchronously with the movable knife; a wear-resistant spacer is arranged between the rear end of the movable knife and the rear end of the fixed knife.

[0007] Preferably, a first groove arranged horizontally and transversely is provided at the lower end of the movable knife fixing frame, the rear end of the movable knife is embedded in the first groove, and the lower edge of the first groove serves as the wear-resistant spacer.

[0008] Preferably, a second groove arranged horizontally and transversely is provided at the upper end of the fixed knife fixing frame, the rear end of the fixed knife is embedded in the second groove, and the upper edge of the second groove serves as the wear-resistant spacer.

[0009] Preferably, the wear-resistant spacer is arranged on the movable knife.

[0010] Preferably, the wear-resistant spacer is arranged on the fixed knife.

[0011] Preferably, the movable knife and the movable knife fixing frame are split structures.

[0012] Preferably, the movable knife and the movable knife fixing frame are fixedly connected by snapping.

[0013] Preferably, a positioning hole and a clamping slot are provided on the movable knife, and a positioning column matched with the positioning hole and a clamping tongue matched with the clamping slot are provided on the movable knife fixing frame.

[0014] Preferably, the fixed knife and the fixed knife fixing frame are split structures.

[0015] Compared with the background technology, the blade structure of the shaver includes a fixed blade assembly and a movable blade assembly horizontally and laterally slidingly matched with the fixed blade assembly, the movable blade assembly is pressed on the fixed blade assembly through a pressure elastic element, the fixed blade assembly includes a fixed blade and a fixed blade fixing frame fixedly connected to the fixed blade, the movable blade assembly includes a movable blade and a movable blade fixing frame moving synchronously with the movable blade; a wear-resistant spacer is arranged between the rear end of the movable blade and the rear end of the fixed blade. In the above blade structure, when the shaver is working, the motor drives the movable blade fixing frame to move, and then the movable blade fixing frame drives the movable blade to perform horizontal and transverse cutting movement relative to the fixed blade. Since the wear-resistant spacer is arranged at the rear end of the fixed blade and the rear end of the movable blade, the rear end of the fixed blade and the rear end of the movable blade are separated from each other, and they will not directly rub against each other, but the rear end of the movable blade or the rear end of the fixed blade will produce friction with the wear-resistant spacer, so that the rear end of the movable blade and the rear end of the fixed blade can be prevented from sticking to each other.

DETAILED DESCRIPTION

[0025] The core of the present invention is to provide a shaver and a blade structure thereof, so as to solve the problem that the rear end of the movable blade and the rear end of the fixed blade of the shaver are easy to stick together.

[0026] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-Figure 6 As shown, a blade structure of a shaver provided by an embodiment of the present invention comprises a fixed knife assembly 1 and a movable knife assembly 2 horizontally and laterally slidably matched with the fixed knife assembly 1, the movable knife assembly 2 is pressed onto the fixed knife assembly 1 through a pressure elastic element 3, the fixed knife assembly 1 comprises a fixed knife 11 and a fixed knife fixing frame 12 fixedly connected to the fixed knife 11, the movable knife assembly 2 comprises a movable knife 21 and a movable knife fixing frame 22 moving synchronously with the movable knife 21; a wear-resistant spacer 4 is arranged between the rear end of the movable knife 21 and the rear end of the fixed knife 11.

[0028] With the above blade structure, when the shaver is working, the motor drives the movable knife fixing frame to move, and then the movable knife fixing frame drives the movable knife to perform horizontal and transverse cutting movement relative to the fixed knife. Since wear-resistant spacers are provided at the rear ends of the fixed knife and the movable knife, the rear ends of the fixed knife and the movable knife are separated from each other and will not directly rub against each other. Instead, the rear end of the movable knife or the rear end of the fixed knife will rub against the wear-resistant spacer, thereby preventing the rear ends of the movable knife and the fixed knife from sticking to each other.

[0029] It should be noted that those skilled in the art should be able to understand that the material of the wear-resistant spacer should be different from the wear-resistant material of the fixed knife and the movable knife, such as non-metallic materials such as wear-resistant resin and wear-resistant ceramic, and of course, it can also be a wear-resistant metal material, such as tungsten carbide, etc. It should also be noted that the pressure elastic element 3 includes a fixed end and a pressure end, and the fixed end can be fixedly connected to the fixed knife fixing frame or fixedly connected to the fixed knife; the pressure end can be fixedly connected to the movable knife fixing frame or fixedly connected to the movable knife, which is not specifically limited here.

[0030] In some more specific embodiments, the number of wear-resistant spacers includes at least two arranged side by side, and symmetrically distributed in the gap between the rear end of the fixed blade and the rear end of the movable blade. By arranging them in the form of segments, the contact area between the fixed blade or the movable blade and the wear-resistant spacer can be further reduced, thereby reducing the friction resistance generated by the relative movement, and the surface of the wear-resistant spacer is preferably smooth, which can reduce the friction coefficient and further reduce the friction resistance. By reducing the friction resistance, the required driving current is reduced during the movement of the blade, and the temperature rise and noise are also reduced accordingly.

[0031] In some more specific embodiments, the wear-resistant spacer may be an integrated structure with the movable knife fixing frame, for example, a first groove 220 arranged horizontally and transversely is provided at the lower end of the movable knife fixing frame 22, the rear end of the movable knife 21 is embedded in the first groove 220, and the lower edge of the first groove 220 serves as the wear-resistant spacer 4. The wear-resistant spacer may also be an integrated structure with the fixed knife fixing frame, for example, a second groove arranged horizontally and transversely is provided at the upper end of the fixed knife fixing frame 1, the rear end of the fixed knife 11 is embedded in the second groove, and the upper edge of the second groove serves as the wear-resistant spacer 4.

[0032] Of course, it can be understood that the above-mentioned structure in which the wear-resistant spacer and the movable blade fixing frame or the fixed blade fixing frame are integrated is only a preferred example of the embodiment of the present invention. In actual application, the wear-resistant spacer 4 can also be directly set on the movable blade 21, or directly set on the fixed blade 11. The specific setting method can be an integrated structure, such as deposition, fusion, welding, etc.; it can also be a split structure, such as screw connection, riveting, etc.

[0033] It should be noted here that the movable knife 21 and the movable knife fixing frame 22 can adopt an integrated structure, such as a structure connected by fusion, welding, etc.; or a split structure, such as a structure connected by screw connection, riveting, clamping, etc.

[0034] In a further embodiment, the movable knife 21 and the movable knife fixing frame 22 are preferably connected by a clamping connection, because the clamping connection is more convenient to disassemble, and when a component is damaged, the corresponding component can be replaced without wasting the entire movable knife assembly.

[0035] The specific structure of the corresponding clamping connection can be that the movable knife 21 is provided with a positioning hole 211 and a clamping slot 212, and the movable knife fixing frame 22 is provided with a positioning column 221 adapted to the positioning hole 211 and a clamping tongue 222 adapted to the clamping slot 212. The positioning hole and the positioning column are used to position the movable knife relative to the movable knife fixing frame in the front, back, left, and right directions, and the clamping tongue and the clamping slot are used to limit and lock the movable knife relative to the movable knife fixing frame in a direction perpendicular to the movable knife fixing frame. Of course, it can be understood that the above-mentioned structural form is only a preferred example of the clamping structure in the embodiment of the present invention. In actual application, other clamping structural forms commonly used by those skilled in the art can also be used.

[0036] In addition, it should be noted that the fixed knife 11 and the fixed knife fixing frame 12 can be an integrated structure, such as a structure connected by fusion or welding; or a split structure, such as a structure connected by screws, rivets, or clamping.

[0037] In addition, the present invention also provides a shaver, including a blade structure, wherein the blade structure is the blade structure described in any of the above schemes. Since the above blade structure has the above technical effects, the shaver having the above blade structure should also have corresponding technical effects, which will not be described in detail here.

[0038] The above is a detailed introduction to the shaver and its blade structure provided by the present invention. It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the various embodiments can be referred to each other.
