Description

[Detailed Description of the Invention] The present invention relates to a bristle material for brushes used in car wash machines.

The general car wash machine shown in FIG.
A lower side cleaning brush 4 is also provided. Each brush 2, 3, 4 is formed by planting a large number of bristles in the length direction and circumferential direction of the rotating shaft. By the way, cleaning efficiency can be improved if each brush 2, 3, 4 contains enough water. Therefore, in order to improve the adhesion of water, conventionally, as shown in FIG. It has a configuration consisting of a plurality of radiating parts 7. According to this, water 8 tends to adhere to the slit portion between the radiating portions 7.

However, in reality, since the radiating portion 7 is straight or has a tapered end, the attached water 8 tends to scatter due to rotation of the brush, etc., so that sufficient cleaning efficiency cannot be expected. Furthermore, since the tip of the radiation part 7 is a corner, there is a risk of damaging the cleaning surface of the car to be washed.

An object of the present invention is to provide a bristle material for a brush for a cleaning machine that can greatly reduce the scattering of adhering water and at the same time prevent damage to the cleaning surface.

In order to achieve the above object, the bristle material of the car wash brush according to the present invention has a cross section in a direction perpendicular to the length direction, which includes a core, a plurality of radiating parts connected from the core, and It is configured to include a circular tip part that is integrated with the free end of the radiating part and has a diameter larger than the thickness of the radiating part.

According to the present invention having such a configuration, water adhering to the slit between the radiating parts is received by the circular tip at the outer end of the slit, resulting in a good water pool (water is difficult to separate). Furthermore, since the tip of the radiation portion is circular, the curved surface comes into contact with the cleaning surface.

An embodiment of the present invention will be described below with reference to FIG. That is, the bristle material 10 includes a core portion 11 whose cross section in a direction perpendicular to the length direction is square;
Four radiating parts 12 are integrally connected from each corner of this core part 11, and a circular tip part 13 is integrated with the free ends of these radiating parts 12 and has a diameter D larger than the thickness t of the radiating parts 12. It was formed from

Therefore, the diameter D of the circular tip 13 is
The outer end of the water 14 adhering to the slit between the radiating parts 12 is larger than the thickness t of the circular tip part 1.
It was caught by 3 and the water was in good condition. Furthermore, since the curved surface of the circular tip 13 comes into contact with the cleaning of the car to be washed, the cleaning surface will never be damaged or the paint will peel off due to the impact upon contact.

In the figure, the cross section is shown as a cross, but
Various modifications such as a star shape in which the radiation part 12 has five are also possible.

According to the present invention having the above structure, the water adhering to the slit between the radiating parts is received by the circular tip at the outer end of the slit, resulting in a good pool of water, which allows the water to accumulate when the brush rotates. The scattering of adhered water can be greatly reduced. Therefore, water droplets can be efficiently dispersed onto the car body to be washed, and the brush with sufficient moisture attached can greatly improve the cleaning effect. In addition, since the curved surface of the circular tip comes into contact with the cleaning surface of the car being washed, it is possible to avoid damaging the cleaning surface or peeling off the paint due to the impact caused by contact, and it is always good. You can wash your car properly.
