Damage-resistance high-performance washing-machine water-level sensor

Abstract

The invention discloses a damage-resistance high-performance washing-machine water-level sensor. The sensor includes an air cover, a terminal and a bracket, a screw hole is formed in the top wall of the bracket, an adjusting nut is installed in the screw hole, and the center of the bottom of the air cover is provided with an air tap. The sensor is characterized in that an adjusting cylinder is not arranged, the adjusting nut is directly arranged on the top wall of the bracket, the bottom of the bracket is provided with a mounting flange, the air cover is fixed on the bracket in a clamped mode, and the bracket is also provided with a lug boss, an insertion groove and a mounting wing plate. Compared with the prior art, the sensor has the advantages that the complicated design is avoided that tapping screws are arranged on traditional sensors, an assembly operation process is simplified, the structure is more simple and reliable, and accumulative errors resulting from excessive assembly links are greatly reduced; because parts are reduced and the structure is optimized, the dropping resistance, deformation resistance and other performances of products are greatly improved, assembly errors resulting from dropping, deformation and the like are reduced, the quality and performance-price ratio of the products are improved, and the sensor is wider in application range.

Description

technical field [0001] The invention relates to the field of electronic sensors, in particular to a damage-resistant high-performance washing machine water level sensor. Background technique [0002] The water level sensor of the washing machine is an important device for detecting and controlling the water level of the washing machine. A traditional washing machine water level sensor usually includes an adjustment cylinder, a bracket, a protective cover and a base, and the protective cover and the bracket are fixed to the base by self-tapping screws. The desired initial frequency is achieved by adjusting the position of the nut, and then the adjusting nut and the bracket are fixed together by hot glue. This fixing method has poor drop resistance, resulting in hidden dangers in product quality; and self-tapping screws are used for fixing, and the torque on the self-tapping screws will also have a negative impact on the position of the inductance coil; at the same time, the ...
