Reusable drying and dehumidifying system for electromagnetic relay

Abstract

The invention discloses a reusable drying and dehumidifying system for an electromagnetic relay. The system comprises a shell, an annular cavity is formed in the shell, silica gel is arranged in the annular cavity, two sliding plates are symmetrically connected to the top in the annular cavity in a sliding mode, the side walls, away from each other, of the two sliding plates are elastically connected with the inner wall of the annular cavity through reset springs, an air suction bag is fixedly connected between the two sliding plates, and a cavity is formed in the bottom in the shell. Water inexternal moisture can be absorbed through silica gel, and the problem that moisture enters the shell to corrode electronic elements in the shell and affect normal use of the electronic elements is avoided. The volume of the silica gel is expanded after moisture absorption, an impeller continuously rotates, a magnetic plate continuously skims over the position under a magnetic sliding plug, and then a spiral coil continuously cuts the magnetic induction line to generate an induction current, so that a heating plate is powered on and heated, the silica gel is heated, moisture in the silica gelis removed, and the silica gel can be recycled.

Description

technical field [0001] The invention relates to the technical field of electromagnetic relays, in particular to a reusable drying and dehumidifying system for electromagnetic relays. Background technique [0002] Electromagnetic relay is an electronic control device. It is actually an automatic switch that uses small current to control large current operation. It is composed of coil loop and contact loop. It uses electromagnetic principle to attract the armature to make the contact loop work, so as to achieve control circuit The purpose of conducting and cutting off. [0003] Due to the diversification of the use environment of the electromagnetic relay, when the electromagnetic relay is used in a dark and humid environment for a long time, due to the high humidity in the dark and humid environment, the external moisture will slowly pass through the gap between the closed shells of the electromagnetic relay. The gap enters the shell, causing corrosion to the electronic comp...

[0003] Due to the diversification of the use environment of the electromagnetic relay, when the electromagnetic relay is used in a dark and humid environment for a long time, due to the high humidity in the dark and humid environment, the external moisture will slowly pass through the gap between the closed shells of the electromagnetic relay. The gap enters the shell, causing corrosion to the electronic components in the electromagnetic relay and affecting the normal use of the electromagnetic relay. At present, after the electromagnetic relay is disassembled regularly by professional staff, the moisture infiltrated inside is dried. The operation is complicated and requires Specific personnel operation, high cost
