Description

Magnetic wiper assembly

Technical Field The utility model relates to equipment for cultivating ornamental fish, in particular to a wiping tool for cleaning the observation window glass of an aquarium.

BACKGROUND OF THE INVENTION In the prior art, the wiping tool used to clean the observation window glass of the aquarium generally adopts a magnetic wiping assembly. The magnetic wiper assembly consists of an internal wiper and a hand-held external wiper. Magnets are installed in both the inner wiper and the outer wiper. Both surfaces of the inner wiper and the outer wiper are attached with stickers that can wipe the aquarium. The material of the wiping surface of the observation window glass, the external wiper slides on the outer surface of the aquarium observation window glass, and the inner wiper on the inner surface of the observation window glass is magnetically pulled to follow the movement, so that the magnetic wiper assembly can clean the inner surface of the aquarium observation window glass and outer surfaces. There is a problem in the use of the magnetic wiper assembly in the prior art: when the inner wiper is separated from the magnetic control of the outer wiper, the outer wiper must be magnetically pulled to follow the movement of the inner wiper again, that is, the entire magnetic wiper assembly must Returning to normal working condition, the solution is more troublesome. Currently commonly used solutions are:

1. When the internal wiper is out of the magnetic control of the external wiper, during the sinking process of the internal wiper or after the internal wiper sinks to the bottom of the aquarium, use your hands or tools to reach into the water and directly fish out the internal wiper. Make the magnetic wipe assembly return to normal working condition.

2. Connect a rope between the inner wiper and the outer wiper. When the inner wiper is out of the magnetic control of the outer wiper, use the rope to pull out the internal components to restore the magnetic wiper assembly to its normal working state.

3. Make the specific gravity of the internal wiper less than that of the liquid in the aquarium. When the internal wiper is separated from the magnetic control of the external wiper, the internal wiper will float to the surface of the liquid in the aquarium, and then try to fiddle with it to the observation window glass inside to restore it to normal working condition.

The above solutions cannot easily restore the normal operation of the magnetic wiper assembly, and when encountering an aquarium with a higher installation position, or an aquarium with a top cover, or an aquarium embedded in the wall, the above method is even more difficult.
