Described second channel open at both ends; Described photoelectron emission device, photoelectric receiving arrangement are divided into second channel two ends, and described second channel is the light-path of photoelectron emission device and photoelectric receiving arrangement;
The inner chamber of described first passage, second channel is filled with low-melting alloy respectively, and first passage, second channel cut off by described low-melting alloy respectively;
Described electric-controlled plate connects fuse, photoelectron emission device and photoelectric receiving arrangement respectively;
Described electric-controlled plate is provided with the broken circuit detection circuit triggered by fuse.
Preferably, in described fuse, the fusing point of melt is 90 ~ 110 DEG C.
Preferably, the fusing point of described low-melting alloy is 120 ~ 160 DEG C.
Preferably, the inner chamber of described first passage and second channel is filled completely by low-melting alloy respectively.
Preferably, described metal master periphery is provided with screw thread, described metal master by its periphery screw thread and diffusion absorption type refrigeration system fastening.
