Why does the triangle disinfection cabinet have a "tick-tock" sound?

1. The door may not be closed properly, resulting in the failure of the protection switch. Users should check whether the door is closed. For example, ZTP80E-3 will call the police when it opens the door, but it will not call the police when it closes the door. When the door switch is broken or the door is closed, the disinfection cabinet with alarm function will give an alarm, and the disinfection cabinet without alarm function will stop working if the work button is pressed and then released. 2. The bump of the door switch is small and easy to break. To replace the door touch switch, you can use pointed scissors to hold the upper and lower concave points on the switch and rotate it 90 to the left to remove the door touch switch. The door can't touch the switch-loosen the upper and lower hinge fixing screws of the door, adjust the door body, make the support of the pressure switch press the protrusion of the door touch switch, and lock the upper and lower hinge fixing screws of the door.
