Further, the air inlet front end is equipped with airscoop shroud.
Further, holder is equipped between the smoke detection unit and shell.
Further, conduction oil is filled in the passage of heat.
The advantageous effect of the utility model compared with prior art：Due to being equipped with heat in the shell residing for smoke detection unit
Channel, and heating unit and temperature sensor are equipped in the passage of heat, smoke detection unit is arranged in the space that the passage of heat is formed,
Ensure that smoke detection unit is positively retained at optimum operating temperature, it is low to solve smoke detection element sensitivity under low-temperature condition
Or the case where can not working, eliminates simultaneously as smoke detection unit is set up directly in low temperature environment and installs detector
Precision problem caused by detection of gas is introduced in room temperature environment；Equipped with the multistage passage of heat, under test gas and the passage of heat are improved
Also contacts area, improve the efficiency of heating surface, ensure the temperature into the gas of smoke detection unit in OK range, heating
Effect is good；It is equipped with heat insulation layer in shell, completely cuts off scattering and disappearing for temperature, reduces the heat generated in smoke detector to low temperature ring
The influence in border；It is equipped with holder between smoke detection unit and shell, prevents smoke detection unit to be in direct contact with the passage of heat, avoids
Apparatus overheat aging；Conduction oil, good heat conduction effect are equipped in the passage of heat.
