Description

Automatic brush for water scrubbing}

The present invention relates to an automatic brush for cleaning water, which can clean a signboard, a wall of a building, or a wall of a swimming pool. More specifically, the hollow shaft of a hollow pipe is mounted on a motor shaft embedded in a portable power tool type drive unit with a built-in motor. One gear of the gear part which is inherently protected and directly connects one end of the long drive connecting rod of which the linear gear is machined to the outer peripheral face of the other end, and the gear processing part of the other end outer peripheral surface of the driving connecting rod directly connected to the motor shaft. After coupling to the brush, the brush is coupled to the brush rotating shaft coupled to the other gear meshed with one gear, and at the same time, the brush is provided with a water supply hose connected from the driving side to the inside of the brush casing along the outer circumferential surface of the hollow pipe. By activating it, you can't reach the signboards, walls, pool walls The present invention relates to an automatic brush for cleaning the water so that the back can be easily cleaned.

In general, to clean the walls, signboards or walls of water tanks or swimming pools that are out of reach of people, a ladder is used, or a plate-like support member that serves as a support plate on which a person can sit or stand is provided. After connecting the rope to a higher position than the cleaning position, such as a roof, a person climbs on the support member tied to the rope to clean with a brush or the like.

However, the cleaning method as described above is inconvenient to change the position of the ladder or the support member frequently according to the cleaning site, and in general, the cleaning itself is very difficult because the cleaning itself almost depends on the power of the person.

In addition, as a cleaning tool for cleaning the floor of a building, various tools have been developed and used that can efficiently clean while minimizing the power of a person, such as a vacuum cleaner, an automatic brush using a motor, and the like. Since tools use motors, their weight increases, which makes them unsuitable for cleaning walls and signs that need to be cleaned with people.

Unlike floor cleaning tools that are placed on the floor and can be easily moved by wheels, etc., cleaning tools such as walls, signboards, and pool walls are subject to weight restrictions due to the nature of lifting the tools by the person. Unlike the cleaning tools, it is difficult to automate using a motor.

In particular, a ladder is generally used for cleaning a place of about 2 to 4 m from the floor, which is approximately the first floor of a building. As described above, there is an inconvenience in that the ladder must be continuously moved according to the cleaning part. In addition, there is a problem that the risk of a safety accident that may injure a person exists because the ladder loses balance and falls due to the movement of a person during cleaning.

In order to solve the above inconveniences and dangers, a cleaning tool such as a brush is connected to a long rod to perform cleaning while standing on the floor without using a ladder. As this becomes small, there is a problem that removal of contaminants is not easy.

In the case of the manual cleaning as described above, there is no suitable means for supplying water to the contaminated site in order to wash away the contaminants to be removed.

That is, when cleaning the wall, signboard, or the wall of the swimming pool, it is inconvenient to spray water separately from the cleaning tool by water pressure through a pump or hose connected to the tap water, or to wet the cleaning tool whenever necessary.

The present invention was devised to solve all the problems of the conventional manual cleaning tools used for cleaning walls, signboards, water tanks or swimming pool walls. It is an object of the present invention to provide an automatic cleaning tool that can be provided with a device that can be supplied to easily clean the wall or signboard with little force.
