BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning brush, and more particularly to a cleaning brush of the kind used for car washing and wall cleaning.

[0002]

2. Description of the Related Art Generally, a cleaning brush of this type has a grip handle having a ring-shaped cleaning member attached to the tip end thereof, or an annular brush having a handle made of synthetic resin and having a hollow end. A brush forming part is provided, bristles are planted on one side surface of the brush forming part, a hose is connected to the water supply port at the rear end of the handle, and water supplied from the hose is sprayed from the bristles to wash the car or It is widely known that the wall surface is cleaned.

However, among the cleaning brushes having such a well-known structure, the former one in which a ring-shaped bundle-like cleaning member is attached to the tip portion of the handle has a force acting on the attachment portion between the cleaning member and the handle. However, there was a problem that the mounting part was easily deformed or broken and the durability was poor. In the latter case, since the hard brush forming part made of synthetic resin is exposed, the hard brush forming part is easy to touch the vehicle body and the wall surface, and the surface to be cleaned such as the vehicle body and the wall surface is not exposed to water. The problem that it is easily scratched because it is rubbed with bristles before it gets wet, and the cleaning brush itself becomes heavy because the water supplied from the hose fills the brush forming part in which the bristles are planted, and a large amount of cleaning operation occurs. There was a problem that it took time and effort.

Therefore, the present applicant has conducted various tests and studies, and has previously proposed a cleaning brush such as that found in Japanese Patent Application No. 5-28829. The cleaning brush according to the previous proposal has cleaning bristles radially formed around the core wire, and ends of the core wire are joined or brought close to each other to form an annular brush portion,
By attaching the end of the core wire to the tip of the handle with the cleaning bristles facing or facing the ends of the core wires joined or close to each other, the brush portion is pressed at two points and This is to disperse the force applied to the end portion, prevent the mounting portion from being damaged early, and improve the durability.

In order to lighten the operation of the cleaning brush, a water supply hose is connected to the rear end of the handle as in Japanese Patent Application No. 4-215067, and the high pressure cleaning water supplied from the water supply hose is brushed. The pressure regulating valve provided on the handle near the part prevents the water supply hose from coming off due to excessive pressure, and the pressure-controlled cleaning water is sprayed from the spray nozzle to be interposed between the bristles and the surface to be cleaned. Therefore, there is a cleaning brush that is lighter in operation and that prevents the cleaning surface from being damaged.

[0006]

However, in the one described in Japanese Patent Application No. 5-288829 mentioned above, when the handle is operated in the direction of pressing the wash hair, this force is dispersed and transmitted to the wash hair. Since the force when pulling up is concentrated on the end of the core wire attached to the tip of the handle, there is a problem that this part will be damaged early, and the durability is sufficiently improved. There was a problem that I couldn't do it.

Further, in the case of controlling the pressure of high-pressure water with a pressure regulating valve as in Japanese Patent Application No. 4-215067, there is a problem that the pressure regulating valve complicates the structure and increases the cost. . Furthermore, when cleaning the surface to be cleaned while spraying cleaning water, when performing a cleaning operation at a place where the handle is higher than horizontal, the sprayed water and the dirty water that has washed the cleaning surface travels through the handle.
There was a problem that it would affect your hands.
