Problems solved by technology

In addition, this razor has a poor beard removal effect in the lower part due to the larger ribs in the lower part; while the ribs in the upper part are smaller, the fixation of the blades in the upper part will be weaker, so the blades in the upper part may It will become warped and affect the effect of shaving
Also, this razor is less well secured by the rib in the upper layer, so the uppermost blade will be perforated and held in place by the post in the upper rib and the cap
However, the cost of machining holes on the blade is relatively high, and the process is difficult.

Embodiment Construction

[0036] figure 1 An exploded view of a preferred embodiment of the razor head according to the invention is shown. The razor head 10 is adapted to be mounted on a suitable handle to form a razor for shaving hair, and is particularly suitable for use as a shaver. The razor head 10 is easy to clean after shaving. In addition, the razor head 10 reduces the possibility of clogging the spaces between the blades during shaving, and thus reduces the number of cleanings during shaving, or even eliminates the need for cleaning during shaving. Such as figure 1 As shown, the razor head 10 includes a cartridge 20, 4 blades 50, 52, 54, 56, a gland 60, a mechanism for guiding hair to the blades (in figure 1 Shown as herringbone groove 74) and lubricating strip 80. see Figure 2-6 , as described in detail below, the four blades are inserted into the space formed by the ribs of the cartridge 20, and the gland 60 is attached (eg, by ultrasonic welding) to the cartridge.

Abstract

The invention provides a razor head which comprises at least one blade, a blade frame and a press cover, wherein the blade frame is provided with a front end and a rear end, and the press cover is connected with the blade frame and is provided with a left side wall and a right side wall. The blade frame comprises at least two groups of ribs which extend from the rear end to the front end. The ribs are arranged at intervals on the length direction of the blade frame. The groups of ribs are approximately positioned on respective planes. The two adjacent groups of ribs are arranged in a mode that one group of ribs are positioned above the other group of ribs, and are spaced apart from each other so as to form a space for containing one blade on the length direction. The blade is positioned between the side walls. The two adjacent groups of ribs are deflected from each other on the vertical direction of the blade frame. The invention also provides a method for manufacturing the razor headaccording to the razor head.

Description

technical field [0001] The invention relates to the field of razors, in particular to a razor head for shaving hair, especially a razor head for shaving. Furthermore, the invention relates to a method of manufacturing a razor head. Background technique [0002] During shaving (usually shaving), the razor head is moved from one part of the skin to another to shave the beard between them, wherein the blades in the razor head cut through the beard to achieve the shaving effect. Severed hairs often fall into the crevices in the shaving heads. Particularly when the razor head has multiple spaced apart blades, severed hairs can fall into the gaps between the blades. [0003] In some existing razor heads, the space between the blades is covered by an intermediate sheet for clamping, so there is no room for hair to fall behind the blades. Make it difficult to clean. [0004] To solve this technical problem, Chinese utility model patent 200720150872.1 provides an easy-to-clean sh...
