Abstract

The invention consists of a floating ball and a sealed plastic case. A magnetic control switch is set in the plastic case. On the outer side of the top of the plastic case, there is a sliding way in which there is a plastic slider in which a magnet is sealed, which is made of NdFeB. The one end of plastic slider is connected with the plastic case through an elastic component, and anther end of it is connected with the floating ball through a connective band. There is a wire connected with the magnetic control switch, and is set in sheath. The plastic case is set under the liquid level, and the floating ball drags the plastic slider. When liquid level raises or drops, the floating ball drags the plastic slider to make its position change. At preset position, the slider overcomes the tensile force of elastic component, and changes the position of magnet to make the magnetic control switch act.

Description

Technical field: [0001] The invention relates to a water treatment device, in particular to a water level height measuring element, in particular to a magnetic control liquid level switch device. Background technique: [0002] In the prior art, a liquid level switch is generally used as a device for detecting the water level, which is suitable for timing and quantitative dosing. The liquid level switch in the prior art is usually composed of a sealed mechanical switch and a lever connected to a floating ball. The floating ball drives the lever, and the lever pushes the switch movable contact. In order to achieve a higher sealing performance of the electrical contact, the liquid level switch in the prior art often adopts a relatively complicated structure, which causes the use cost to be too high. Summary of the invention: [0003] The technical problem in the prior art to be solved by the present invention is: because the liquid level switch in the prior art is usually composed ...
