Floating-ball switch

Abstract

The invention relates to a floating-ball switch. The floating-ball switch is a liquid level control device. The switch mainly comprises a floating-ball control mechanism, a displacement swing arm mechanism and a contactor. The floating-ball control mechanism is connected with the displacement swing arm mechanism through a screw directly, and the displacement swing arm mechanism is connected with the contactor through a rocking arm to form a whole. During the operation, on and off of a water pump power supply is controlled by the floating-ball control mechanism, the displacement swing arm mechanism and the contactor through the floating ball weight and floating force. The switch is simple in structure, capable of controlling the water pump power supply directly, high in reliability, capable of not consuming electricity, convenient to mount and capable of not changing a water tank, saving power and water and achieving unmanned watch. Meanwhile, the floating-ball control mechanism, the displacement swing arm mechanism and the contactor can be combined respectively to achieve different control functions; the switch is particularly applicable to liquid level control of water tanks and water ponds.

Description

technical field [0001] The invention relates to a float switch, in particular to a liquid level control device with a displacement swing arm mechanism, which is especially suitable for controlling the liquid level of water tanks and pools. Background technique [0002] With the general improvement of living standards in the vast rural areas of our country, household water tanks have been widely used, but most of the water supply to the water tanks is still controlled manually, that is, it is not known to add water to the water tank until the tap does not discharge water, and when the water pump is powered on, it needs to Always pay attention to the overflow pipe above the water tank, once the water comes out, immediately cut off the power supply of the water pump. This water supply method is a waste of time on the one hand, and on the other hand, forgetting to turn off the water will cause a large amount of water to flow out from the overflow pipe, resulting in the loss of w...

AI Technical Summary

Problems solved by technology

This method of water supply is a waste of time, and the second is that forgetting to turn off the water will cause a large amount of water to flow out of the overflow pipe, resulting in the loss of water resources

Third, forgetting to fill the water will lead to abnormal water use

At present, there are electronically controlled automatic water fillers that are common in the market. The structure is complex, and the water tank needs to be greatly modified. It is inconvenient to install, so the cost is high, and it is difficult for users to accept.
