Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cutter for cutting hair.

[0002]

2. Description of the Related Art For hair cutters used at home, it is desired that hair scraps do not scatter on the floor or the like. For this reason, for example, Japanese Utility Model Laid-Open No. 51-1183.
Various types have been proposed that employ a suction method such as that shown in Japanese Patent Laid-Open No. 88, which is capable of sucking the cut dust a and storing it in the storage case 100, but has not yet been put to practical use.

[0003]

The reason for this is that in the suction type as described above, as shown in FIG. 17, the hair scrap receiving portion 50 is provided on the movable blade 21 side, and the cut hair is cut. This is because the scrap a will be repelled by the reciprocating movable blade 21, and even if there is suction means, scattering of the scrap by the movable blade 21 will increase.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a hair cutter capable of cutting hair without scattering hair scraps.

[0005]

SUMMARY OF THE INVENTION According to the present invention, however, a blade member comprising a comb-shaped fixed blade and a movable blade is provided, and a pair of hair supporting members arranged on both surfaces of the blade member. The cutting action portion of the blade portion is located in the vicinity of the line connecting the tips of the two support members, and the comb portion projects from the tip of the movable blade side support member. And a suction means communicating with the hair scrap receiving portion.

[0006]

According to the present invention, due to the presence of the pair of support members, it is possible to prevent the hair from being cut by being cut by the cutting action portion of the blade portion, and at the same time, to remove the hair that has come off one of the support members. Only the tip reaches the cutting action part of the blade and is cut, and a simple step cut can be performed simply by moving the hair along the flow of the hair while combing the hair. And
The hair scraps after cutting are stored in the hair scraper receiving portion provided on the fixed blade side by the suction means, and the hair can be cut without being scattered by the reciprocating movable blade.
