Abstract

The invention discloses a liquid level switch, which belongs to the field of a liquid level sensor. The traditional liquid level switch has defects that an installation mechanism is inconvenient to operate and easy to damage. The liquid level switch comprises a supporting column, a limiting clamping sheet, a floater and an installation mechanism, wherein a sensing element is arranged inside the supporting column, a magnetic ring is embedded inside the floater, the floater is provided with a through hole, the through hole runs through the center of the magnetic ring, the floater is sleeved on the supporting column, the floater can move up and down on the supporting column, and the sensing element is paired with the magnetic ring to form a sensing mechanism; and the limiting clamping sheet is installed on one end part of the supporting column, the installation mechanism is installed on the other end of the supporting column, and the installation mechanism is a push-clamping structure and tightened by a screw. Due to adopting the liquid level switch, the firmness in installation is effectively enhanced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of liquid level sensors, and in particular relates to a liquid level switch. Background technique [0002] The liquid level switch is used to realize the detection of the liquid level height, and it is widely used in household appliances, automobiles and other fields, such as the automatic drainage system of the ceiling or mobile air conditioner, the liquid level control system of the automobile, etc., the liquid level switch is used as An automatic liquid level control component, usually together with an actuator (such as a drainage pump, etc.) to realize the control of the liquid level. Existing liquid level switches such as figure 1 As shown, it generally includes a pillar 3 and a float 4. The pillar 3 is provided with an inductive element, and the float 4 is embedded with a magnetic ring 10 and a through hole passing through the center of the magnetic ring. The magnetic ring 10 is set on the pillar 3 by the flo...
