A magnetic brush for automatically cleaning fish tanks

Abstract

The invention discloses a magnetic brush for automatically cleaning fish tanks, which comprises a tank inner brush placed on the inner wall of the fish tank and an outer tank brush placed on the outer wall of the fish tank and magnetically attracted to the inner brush in the tank. Both the outer tank brush and the inner brush are equipped with Permanent magnet, the inner side of the brush outside the cylinder and the inner side of the brush inside the cylinder can be attracted to each other through the permanent magnet, the brush outside the cylinder is formed with an installation cavity, the installation cavity is provided with a cover plate, and a drive unit is provided in the installation cavity, the drive unit includes a battery, The motor electrically connected to the battery, the eccentric head connected to the output shaft of the motor, the front end of the installation cavity is provided with a connecting frame, the eccentric shaft at the front end of the eccentric head is inserted into the bayonet of the connecting frame, the front end of the connecting frame is connected with the driving head, and the driving head is set There is at least one outer magnet, and the cleaning head is movably set on the front end of the brush in the tank. The cleaning head is provided with an inner magnet that attracts the outer magnet. A cleaning unit is provided on the surface of the cleaning head in contact with the fish tank. The design is reasonable and the labor intensity is small. , One-time cleaning effect is good.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a magnetic brush for automatically cleaning fish tanks. Background technique [0002] After the fish tank is used for a period of time, stains and algae, such as moss, will accumulate on the inner wall of the fish tank, so it is necessary to replace the water and clean the inner wall of the fish tank regularly. [0003] The existing magnetic brush is composed of an inner brush and an outer brush. Through the adsorption of magnets, the outer brush of the moving cylinder drives the inner brush to move to clean the inner wall of the fish tank. However, some difficulties may appear on the inner wall of the fish tank during the use of the fish tank. To clean up the stains and algae, it is necessary to move the outer brush and the inner brush back and forth to clean these places. During the operation, the outer brush will move too fast, which will cause the inner brush to separate from the outer br...

Problems solved by technology

[0003] The existing magnetic brush is composed of an inner brush and an outer brush. Through the adsorption of magnets, the outer brush of the moving cylinder drives the inner brush to move to clean the inner wall of the fish tank. However, some difficulties may appear on the inner wall of the fish tank during the use of the fish tank. To clean up the stains and algae, it is necessary to move the outer brush and the inner brush back and forth to clean these places. During the operation, the outer brush will move too fast, which will cause the inner brush to separate from the outer brush, so it needs to be re-installed. Adsorbing the inner brush and the outer brush is a waste of time. To clean the same stain, the outer brush needs to be moved back and forth many times, which is labor-intensive
