Preferably, ventilation opening axle center array is arranged on fuselage outer side surface, and runs through annular protrusion.
Compared with prior art, the utility model has the beneficial effect that the fuselage interior of this fire-fighting sense cigarette detector
Bottom end and the concentric position of fuselage are equipped with annular protrusion, and are accommodated by forming an annular between annular protrusion and fuselage
Chamber is equipped with protective device inside accommodating chamber, extraneous dust and moisture infiltration can be prevented into detector by protective device
Inside, solving leads to that the forecast is inaccurate really because dust or moisture enter inside detector, or even the problem of can not work, prevents simultaneously
The guard shield of protection unit is by being fastened and connected in fuselage interior, convenient for the disassembly of guard shield, and can be to protection
Dust guard and water-tight device on device are cleaned or are replaced.
