Description

Hair trimmer

Technical Field

The present invention relates to a hair trimmer.

Background

In the' 201520235738.6 patent application, a stationary blade and blade set is disclosed, in particular, as shown in fig. 1, the stationary blade being arranged to move through hair in a direction of movement for cutting the hair, comprising a first wall portion arranged to function in operation as a skin-facing wall, a second wall portion offset from the first wall portion such that the first and second wall portions define a guide slot therebetween arranged to receive a movable cutting blade, at least one toothed leading edge formed by the first and second wall portions together, wherein the at least one toothed leading edge comprises a plurality of teeth, wherein the first and second wall portions are connected at a front end of the at least one leading edge, thereby forming tips of the teeth, wherein the stationary blade is an integrally formed metal-plastic composite stationary blade, wherein the first wall portion is at least partially made of a metal material, and wherein the second wall portion is at least partially made of a plastic material. In the above patent, in order to secure the strength of the stationary blade, the second wall portion is provided to reinforce the strength of the first wall portion. The second wall portion for reinforcement is again provided at least partly of a plastic material, which, after being provided, to a certain extent meets the strength required for a thinner stationary knife, but the forming process and costs are high. In addition, in order to achieve better cutting effect by cutting shorter hair, the blade assembly in the prior art needs to be provided with a supporting structure (a fixed blade seat) used in cooperation with the fixed blade to increase the strength of the fixed blade, so that the phenomenon that the moving blade shakes or jumps when the moving blade is used due to the fact that the fixed blade bends and deforms in the direction perpendicular to the moving direction of the moving blade is avoided. In general, there is also a blade set in the prior art, in which a support structure for supporting a stationary blade is provided, the support structure having a wall portion along the moving direction of the movable blade, by which wall portion the wall portion of the movable blade is supported. Although this form can also enhance the strength of the static knife to some extent, it requires an increase in the supporting structure, which is equivalent to an increase in the thickness of the whole static knife tooth, and therefore, this design cannot be used to cut short hairs, or when cutting short hairs, the cutting effect is not ideal.

Due to the high precision required by the razor in cutting, the requirements on the fit of the various elements in the razor blade set are high, and even if the precision required is a few tenths of a millimeter worse, the hair may not be cut and may be pulled or jump. The die opening cost and the difficulty of the manufacturing process are multiplied for each added element. Accordingly, as can be appreciated from the foregoing description of the prior art, none of the existing razor blade sets simultaneously address the issues of strength, cutting effectiveness, and manufacturing process of the razor.
