First embodiment
Through the applicant the study found that with the density of population of the quickening of urbanization process and residential block and shopping centre
It increases rapidly, all types of sensor alarms enters people’s lives on a large scale, and wherein fire source probing device is due to right
The prevention and alarm of fire play an important role, but existing fire source probing device can be divided into according to the difference of detection principle
Feel cigarette formula, photosensitizing type, detection of gas formula and temp.-measuring type.But feels cigarette formula and gas type detection device is suitable for closing, is short-range
Environment is detected, in opening or long distance environment, smog, gas diffusion are fast, are not easy collected detection；Photosensitizing type is then in burning things which may cause a fire disaster
Cigarette ash by larger limitation when being stopped, such as on cigarette butt can seriously affect detection accuracy and the spirit of photosensitizing type detector
Sensitivity；Existing frequently-used temp.-measuring type fire source probing device generally uses large area array infrared thermal imaging photosensitive element, and there are photosensitive elements
It is of high cost, not with universal problem.To solve the above-mentioned problems, a kind of fire source probing device 100 is present embodiments provided.
It please refers to Fig.1 and Fig. 2, Fig. 1 is a kind of fire source probing device for providing of the utility model first embodiment first
Structural schematic diagram under visual angle, Fig. 2 are a kind of fire source probing device for providing of the utility model first embodiment at the second visual angle
Under structural schematic diagram.
