Fixed cutter, electric shaving tool bit applying fixed cutter and manufacturing method thereof

Abstract

The invention discloses a reciprocating type linear cutting electric shaving tool bit which comprises a fixed cutter support and a fixed cutter, wherein the fixed cutter support is provided with a left supporting part and a right supporting part for supporting the fixed cutter from the two sides, an inner containing cavity is formed between the fixed cutter and the fixed cutter support, a hair inlet groove is formed between the fixed cutter and the fixed cutter support, and a movable cutter matched with the fixed cutter is arranged in the inner containing cavity, a middle mounting hole is formed in the middle of the top wall of the fixed cutter, a middle cutter net which penetrates through the middle mounting hole and protrudes above the top surface of the fixed cutter is arranged in the inner containing cavity, and a middle cutter which is matched with the middle cutter net and can reciprocate back and forth for cutting is arranged below the middle cutter net; and also comprises a transmission part which is used for connecting the movable cutter and the middle cutter with a power device of an electric shaver; the invention further discloses the fixed cutter used for the electric shaving tool bit. The invention further discloses a method for manufacturing the electric shaving tool bit. The electric shaving tool bit is simple in structure, small in size and good in cutting performance, and has the cutting function of protruding from the middle to the upper portion of the fixed cutter.

Description

【Technical field】 [0001] The invention relates to a fixed knife of a reciprocating linear cutting electric razor head. The invention also relates to a reciprocating linear cutting electric razor head. The invention also relates to a reciprocating linear cutting electric razor head. The hairy knife method. 【Background technique】 [0002] The existing reciprocating linear motion razor heads usually have the characteristics of small size, flexible use, and sharp cutting. Generally, the fixed knife is fixed by the fixed knife bracket to form a cavity for the linear movement of the movable knife, and then Form a cutting surface on the top surface of the fixed knife, and cut from the left and right sides. This type of reciprocating razor head, because the fixed knife is fixed on the fixed knife bracket from both sides by metal sheet, the fixed knife is an integral structure, and the fixed knife is made of a very thin metal sheet, Usually the thickness is the same, that is, there...

AI Technical Summary

Problems solved by technology

This type of reciprocating razor head, because the fixed knife is fixed on the fixed knife bracket from both sides by metal sheet, the fixed knife is an integral structure, and the fixed knife is made of a very thin metal sheet, Usually the thickness is the same, that is, there is only one thickness when cutting. Although it meets the cutting requirements well, the function is relatively single, and the user experience needs to be further improved.

However, due to its small size, in the industry of reciprocating razors, it is generally believed that the design space for this type of product is already very small. The connection structure between the knife brackets, the cooperation between the moving knife and the fixed knife and the fixed knife bracket do some specific optimization designs, such as the patent of the blade group and its manufacturing method with the publication number CN109623884A, a problem faced is exactly difficult to break through the existing technical limitations
