Abstract

The invention discloses a water level sensor structure. The water level sensor structure is characterized by comprising an upper housing and an air inlet cover matched with the upper housing to form an inner cavity through installation, wherein a partition film for dividing the inner cavity into two cavities is arranged between the air inlet cover and the upper housing, an air inlet nozzle communicated with the lower cavity is formed in the air inlet cover, and an oscillating circuit (LC) is arranged in the upper cavity. The LC comprises a coil framework, the outer side of the coil framework is wound by an enameled wire, and a plug hole for penetrating through a terminal is formed in the coil framework. A positioning hole correspondingly connected to the upper housing is formed in the edgeof the coil framework, and a positioning pin is arranged on the inner wall of the upper housing, is correspondingly plug-connected in the positioning hole and adopts welding positioning. The water level sensor structure can be suitable for batch production, the pass percent of produced products is high, and the water level sensor is low in cost and high in stability and has better application prospect.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to the structure of a water level sensor. Background technique [0002] It is already known in this field that the ① water level sensor or pressure switch used in the washing machine, through the LC oscillation circuit (Colpitts type), Hz, where L is the inductance of the coil in Hz, and C is the electrostatic capacity of the capacitor F; during the operation of the washing machine, multiple parameters are set to ensure the normal operation of the equipment; figure 1 As shown in , one end of the inlet nozzle of the water level sensor 16 is connected to the air collection chamber 19 in the washing machine inner drum 18 through a hose 17 to form a complete washing machine inner drum liquid level detection system. In the prior art, most water level sensors have complex structures, cumbersome installation processes and poor stability. Contents of the invention [00...
