Description

[Detailed description of the invention] This invention relates to the improvement of a brush for cleaning hair debris from electric razors, by making the effective cleaning length of the bristle bundle variable, so that one brush can be adapted to various complex shapes of electric razors. It is possible to provide a brush with a simple structure.

Generally, this type of brush 50 has a tip base 52 of a grip portion 51.
Conventionally, the reason why a large number of synthetic fiber hair bundles 53 are implanted is that the entire length of the hair bundles is the same, so that the same elastic force can be obtained over the entire hair bundle.

On the other hand, the cleaning parts of the electric shaver include the inner surface of the outer cutter 54 as shown in FIG. 1, the cutting edge of the inner cutter 55 shown in FIG.
The threaded portion 57 of the main body case 56 to which the main body case 56 is screwed, etc., has various complicated shapes.

Therefore, if these many complex-shaped parts were cleaned with the brush 50 made of the bristle bundles having the same elasticity over the entire area, satisfactory cleaning could not be achieved.

The fundamental cause of this is that, as shown in Fig. 3, the hair scale and cortex K firmly attached to the curved side 55a of the cutting edge of the inner cutter 55 must be forcibly scraped off with the brush 50, and as a result, the hair As shown in FIG. 4, the tip is rounded and has a tendency to bend, and even if the brush 50 with this bending tendency is used to sweep the beard debris from the inner surface of the outer blade 54, it will reliably follow the inner surface as shown in FIG. Without,
They tend to fall apart, reducing cleaning effectiveness.

Therefore, in order to eliminate the above-mentioned drawbacks, a sliding type bristle holding plate (not shown) that can slide around the bristle strand of the brush 50 and can be slid around the bristle strand of the brush 50 has been provided, and the effective length of the bristle strand can be varied. However, this method requires a complicated locking positioning means to satisfy the contradictory conditions of the presser plate not shaking during use and that it is easy to slide. The plate is designed to prevent it from easily falling off the brush, so when cleaning the lint that has entered between the bristle bundles, the presser plate gets in the way and can cause too much clumps of bristle to be removed. It had the drawback of sometimes staining other parts.

In order to eliminate these drawbacks, this invention has a hair bundle implanted in a synthetic resin base at the tip of the grip, and a hair bundle is attached to both sides of the hair bundle in the longitudinal direction from the base via a thin hinge part. This is an integrally extended holding plate.

Examples of this invention will be described below with reference to the drawings.

In FIG. 6, reference numeral 1 denotes a grip part, and a large number of hair bundles 3 are planted at the base 2 of this tip, and the longitudinal direction P of the hair bundles 3 is
Hair bundle pressing plates 5 and 6 are integrally extended from the base 2 via a thin hinge portion 4 on both sides of the hair.

In this case, a protrusion 7 having a spherical tip is provided on the right side bristle presser plate 5, and a recess 8 into which the tip of the protrusion 7 fits is provided on the left side bristle presser plate 6.

The length L of the presser plates 5 and 6 is set to approximately I of the total length l of the hair bundle 3, as shown in FIG.

Also, grip part 1. Base 29 Hair bundle 39 Hair bundle pressing plate 5, 6. Each of the protrusions 7 is integrally molded from a flexible synthetic resin such as nylon resin or polypropylene resin.

Therefore, since the entire product can be produced in one molding process, no processing effort is required, making it inexpensive and ideal for mass production.

In the brush having such a structure, as shown in FIG. 8, the left and right bristle holding plates 5 and 6 are bent from the hinge part 4 so as to face each other, and the protrusion 7 is inserted into the recess 8 through which the bristle 3 is inserted. If the bristle bundle 3 is press-fitted, the effective cleaning length S of the hair bundle 3 is l-L.
As a result, the elasticity of the hair bundle 3 is increased, and it is possible to scrape away the hair scale, cortex, etc. stubbornly adhered to the back of the cutting edge of the inner blade of the electric razor. Even if you press it strongly against the surface to be cleaned, the hair strands 3 are stuck to the presser plate 5.
．． 6, there is no possibility that a curl-like bending tendency will remain at the tip of the hair bundle 3.

In addition, when cleaning deep areas such as the inner surface of the outer cutter that is easily damaged or the threaded groove of the outer cutter holder, the effective length of the bristle bundle 3 can be increased by opening the presser plates 5 and 6 as shown in Fig. 7. (S-
L) is made longer and has a softer elasticity, allowing you to clean every nook and cranny.

If the open presser plates 5 and 6 become a hindrance to the cleaning operation, hook-shaped protrusions 9 are provided on the end surfaces of the presser plates 5 and 6 as shown in FIG. What is necessary is to provide an engagement recess 10 in which the hook-shaped projection 9 is engaged.

Furthermore, with frequent use, lint may become hidden between the 3 strands of the brush's bristles and scatter at unexpected times, but with this one, the presser plates 5 and 6 can be completely opened, making it easy to clean the brush. It is possible.

This effect is due to the fact that compared to the conventional sliding presser plate type, the sliding type requires a separate presser plate from the brush body, and this sliding presser plate can easily be used with the presser force applied during use. In order to prevent the hair from slipping off from the base, a secure means of locking is required, which not only makes the structure complicated and expensive, but also prevents the sliding presser plate from coming off easily. It has many drawbacks, such as the fact that hidden hair particles gradually accumulate and tend to be carelessly scattered around, and the sliding presser plate gets in the way when removing this hair particles, making it difficult to clean as desired. However, with the brush according to this invention, all of these problems can be solved.

In the above-mentioned embodiment, the connecting means for the presser plates 5 and 6 is constructed of the protrusion 7 and the recess 8, but other known connecting means may also be used.

Further, in the above embodiment, all the brushes were integrally molded from the same resin, but the grip portion 1, the protrusion 7, etc. may be made of various materials depending on the design.

As described above, according to the brush of this invention, the elasticity of the bristle bundle can be used properly depending on the area to be cleaned, and the presser plate 5.6 for this purpose is connected to the base 2 and the thin hinge part. Since it can be integrally molded through 4, it does not require much processing time and can be mass-produced at low cost.

Furthermore, since the presser plates 5 and 6 can be fully opened from the hinge portion 4 with respect to the hair bundles 3, cleaning of hair debris between the hair bundles 3 can be facilitated.
