When the box door 1 is closed, the box door 1 applies force to the action reed of the microswitch 7 to quickly connect the movable contact and the fixed contact at the tail end of the action reed, so that the infrared induction acousto-optic alarm module 41 is electrified to enter a working state; when the box door 1 is opened, after the acting force on the transmission element is removed, the action reed generates reverse action force, the movable contact and the fixed contact at the tail end of the action reed are quickly disconnected, and the infrared induction acousto-optic alarm module 41 is powered off to stop working.

A gap of 10-15cm is left between the partition plate 3 and the top of the box cover 5. The temperature of the large chamber 22 and the small chamber 21 can be ensured to be consistent through the gap.

The side wall of the rear side of the box body 2 is provided with a threading hole 23. The wires in the box body 2 penetrate through the threading holes 23 to be connected with the electric elements outside the box body 2.
