Embodiment

[0012] Such as figure 1 , figure 2 As shown, the invention discloses a design scheme of a moisture-proof switch. A moisture-proof switch is mainly composed of a sealed shell 1, an internal conductive part, and a drying box 2. There is a wire sealing ring at the entrance of the external wire, and a drying box is arranged in the switch shell 1. The drying box 1 is a turntable structure, with a circular turntable 3 at the bottom, and a partition barrier 4 on the turntable, which divides the drying box into two independent drying chambers 5, each drying chamber 5 places a drying ball, and the turntable 3 Align one of the drying chambers to the inside of the switch while the other 5 is turned to the outside of the switch. The drying box 2 has a humidity switch door 6 towards the inside of the switch, and the humidity switch door has a humidity detector 7. When the humidity value reaches 40%, the humidity switch door 6 is started to open the door, as figure 2 As shown; when it...

Abstract

The invention provides a moisture-proof switch. The moisture-proof switch is composed of a sealed casing and an internal conductive component, the inlet of an external wire is provided with a wire seal ring, a drying box in which drying balls are arranged is arranged inside the casing, the drying box is provided with a humidity opening and closing door, when the air humidity inside the switch exceeds a fixed value, the humidity opening and closing door is opened, and when the drying balls absorb moisture inside the switch to a humidity value lower than the fixed value, the humidity opening and closing door is closed. The drying box is of a rotating disc type structure, the bottom of the drying box is provided with a rotating disc, and the inside of the drying box is provided with two separate drying rooms inside which one drying ball is arranged respectively, a user can replace the drying balls at any time by rotating the rotating disc to enable one drying room to aim at the inside of the switch and enable the other drying room to rotate to the outside of the switch. The drying box is provided with an alarm, when the humidity opening and closing door is opened, the humidity value cannot be reduced at a certain time, the rotating disc of the drying box rotates to enable the drying room needing changing the drying ball to rotate towards the outside of the switch, and the alarm reminds the user to change the drying ball. By means of the moisture-proof switch, the moisture-proof performance of the switch can be improved continuously to further guarantee the normal operation of the switch, and the safety factor of switch using is improved.

Description

technical field [0001] The invention belongs to the field of switch function expansion, in particular to a moisture-proof switch. Background technique [0002] Generally, in a normal environment, the switch does not need special moisture-proof measures, but for places with high humidity and bathrooms, the moisture-proof property of the switch is a very important factor. The moisture-proof performance of the switch is low, which will not only affect the use of electrical appliances, but also cause casualties due to leakage. Ordinary moisture-proof switches just add a sealing ring or a simple plastic cover to the shell. This kind of switch cannot play a good role in moisture-proof, and the gap is still large. It is still prone to poor operation of the switch after being wet, or electric shock. Therefore, how to ensure the moisture-proof performance of the switch is a problem worth solving. Contents of the invention [0003] The present invention provides a moisture-proof s...
