Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF APPLICATION IN FL INDUSTRY The present invention relates to a rotary hand polisher brush for polishing surfaces and three-dimensional surfaces.

2. Description of the Related Art A conventional hand brush t#-brush will be explained with reference to FIGS. 3 to 5. J3 in Figure 3 and Figure 4, 11
are brush bristles made of the same material, 12 is a circular brush base on which the brush bristles 11 are flocked, 13 is a rotating shaft for rotating the brush base 12, and 14 houses a power switch 15, a motor, a reduction gear, etc. This is the main body of Polyrasha. As shown in FIG. 4, the brush portion is connected to the rotating shaft at appropriate intervals on a plurality of straight lines parallel to the rotating shaft 13 that are parallel to the rotating shaft 13 in the circumferential direction on the outer peripheral surface of the brush base 12 that rotates together with the rotating shaft 13. Brush bristles 11 are flocked in a radial direction perpendicular to the bristles 13, and by rotating the brush base 12 and rotating the bristles 11, floors, walls, or articles are polished.

This type of hand polisher brush is a hand-held type, so it has a large eaves structure, and the force to press it against the polishing surface is mainly human power. In addition, when the columnar brush surface made up of the tips of the brush bristles 11 is applied to the polished surface,
Since the brush bristles 11 are radially flocked as shown in FIG. 4, the brush bristles 11 are strong and difficult to bend.
A large vibration occurs in the polygon body 14, similar to when a polygonal prism formed by connecting the tips of the polygons 1 in the circumferential direction with straight lines is applied to the polishing surface and rotated, and the hand holding the body 14 of the Borisshi 1p vibrates, causing a very strong vibration. As you get tired, you won't be able to press the polisher enough and it will end up floating, making it impossible to work stably.

For this reason, as shown in Fig. 5, between adjacent straight lines on the outer peripheral surface of the brush base on which the brush bristles shown in Fig. 3 have been implanted, brush bristles made of different materials are placed at appropriate intervals on a straight line parallel to the rotation axis. There is a method in which the bristles are planted in a staggered manner as a whole, and the tips of the bristles are tied in a straight line in the circumferential direction to form a polygonal column that is further polygonal to approximate internal rotation. In Fig. 5, 21 is a hole for implanting brush bristles made of material A, which has high strength, and 22 is a hole for implanting brush bristles of august quality that has good water retention. We are trying to improve usability by using integrated tIC.

Problems to be Solved by the Invention However, in the hand brush as shown in FIG. Because of this, when the brush part is placed against the polishing surface and rotated, the A41-quality brush bristles and the 844-quality brush bristles lined up in rows alternately, making it difficult to use and shortening the service life. It got dark.

The present invention solves the above-mentioned problems, and aims to provide a hand bolisher brush that is easy to use and has a long life.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a method in which the brush bristles are arranged in a staggered manner on a plurality of straight lines parallel to the rotation axis of the outer peripheral surface of the brush base. The bristles on each straight line are alternately arranged and made of different materials, and the bristles made of the same material are arranged spirally on the outer peripheral surface.

Effect With the above configuration, the brush base can be applied on the outer peripheral surface of the brush base on a straight line parallel to the rotation axis or on a circumference in a plane perpendicular to the rotation axis.
Brush bristles made of different materials are arranged alternately,
The brush bristles that hit the polishing surface alternate, but bristles made of different materials hit the polishing surface at the same time.Moreover, when looking at brush bristles made of the same material on the outer peripheral surface of the brush base, continuous spirals in the circumferential direction rotate sequentially. It has a movable shape, and when the brush part touches the polishing surface, there is less vibration when it rotates, making it easier to use and improving water retention.

Furthermore, since 44 different types of bristles are always in contact with the polishing surface at the same time, the constant force applied to the brush part prevents the softer bristles from being unduly pressed, greatly extending the life of the bristles. It is possible to postpone it.

Example An embodiment of the present invention will be explained below based on the drawings.

FIG. 1 is a partially omitted front view of a brush portion of a hand polisher brush showing an embodiment of the present invention.

In Fig. 1, 1 is a hole for implanting strong A'@ quality brush bristles, 2 is a hole for implanting 844 quality brush bristles with good water retention, 3 is a cylindrical brush base, and 4 is this hole. This is the rotating shaft that rotates the brush base. These holes 1 and 2 are arranged on a plurality of straight lines parallel to the rotating shaft 4 parallel to each other in the circumferential direction on the outer circumferential surface 3a of the brush base 3, and are staggered with respect to each other on adjacent straight lines. The holes 1 and 2 are arranged alternately on each straight line, and the first
As shown in the figure, the holes 1 and 2 are connected in a spiral manner on the outer peripheral surface 3a, and this spiral shape has 4433 patterns arranged alternately in the direction of the rotation axis.

Further, on the circumference of the city perpendicular to the rotation axis 4, the positions are 1, 2' and 1'' or 2, 1' and 2''.

The brush bristles planted in these holes 1.2 extend radially orthogonally to the rotating shaft 4, as in the conventional case.

Next, the effect will be explained using the drawing of FIG. 2 when the brush part is applied to the polished surface. In FIG. 2, reference numeral 5 indicates brush bristles of A material that are implanted in hole 1, 6 indicates brush bristles of B44 material that are implanted in hole 2, and 7t indicates a polished surface. In this way, the brush bristles 5 and 6 alternate on the straight line parallel to the rotation axis 4, and since there are brush bristles 5 and 6 made of the same material even on adjacent straight lines, the holes shown in FIG. 1 and 2
The brush bristles 5 and 6 touch the rotary shaft 4 at the same time in the axial direction, and when the brush part rotates, the position where the brush bristles 5 and 6 touch the polisher 7 changes, for example, the holes 2' and 1' shown in FIG. The brush bristles 6 and 5 come into contact with each other in the axial direction, and the brush bristles 5,
6 always hits at the same time. In this way, the brush bristles 5 and 6 made of different materials A and B hit the polishing surface while changing sequentially in the axial direction and the circumferential direction, so when the brush part is applied to the polishing surface 7 and rotated. There is less vibration, and the brush bristles 5.6 of the different materials A and 8 hit the polishing surface 7 at an appropriate fPJ, so the water retention is good and the strength is appropriate, and the brush bristles 141? The force applied per bristles is also made uniform, and the lifespan can be significantly extended.

Effects of the Invention According to the present invention, the brush bristles that hit the polishing surface alternately as the brush part rotates, or the bristles made of different materials hit the polishing surface all at the same time. Since the contact position is sequentially moved along the axial direction of the rotating shaft, vibration is reduced, usability is improved, and water retention is improved. Also, since the brush bristles made of the same material are never used to polish the same area, there is no risk of damaging the polisher. Furthermore, since the force applied to each material is equalized, the life of the brush bristles can be significantly extended.
