The purpose of this utility model is; the problem existing for prior art; a kind of device that improves infrared sensor detection accuracy is provided; it is a kind of infrared sensor protective device; this device can greatly alleviate the dust that produces in the working environments such as dust, smog, smog etc. in the crystallization of infrared sensor detecting head surface and the adsorption phenomena of condensing; guarantee the clean of infrared sensor working environment, improved the detection accuracy of infrared sensor.
A kind of infrared sensor protective device that the utility model provides; it is characterized in that this device comprises top cover, base; top cover comprises top and neck; from top one side direction of top cover, extend to form a right cylinder projection; right cylinder projection inside has air intake opening; in top cover, be provided with one section of top cover cavity matching with infrared probe gap, described cavity is convex structure.From top and neck intersection, to top cover inwall, extend to form a ring groove, the midsection of described ring groove is ear shape structure, and this ring groove and described top cover cavity form a boss top cover is inner, makes gas uniform and distribute circulation.This ring groove communicates with air admission hole.Base is provided with the base cavity pocket matching with infrared sensor sound end, on base, inwall and top cover top are threaded connection fixing, under base, inwall and infrared sensor join with thread forms, the screw thread place that described base connects infrared sensor has several small through hole, and described small through hole is evenly arranges.On the neck inwall of top cover, base, respectively and between infrared sensor, form certain annular gap, base extends to form base cavity pocket downwards to inwall, and described air intake opening, ring groove, gap, several apertures and base cavity pocket form gas passage.
From air intake opening input inert gas, gas enters top cover ring groove from air intake opening, be full of top cover inside cavity gas uniform, gas is respectively by the annular gap between top cover, base and infrared sensor subsequently, air-flow circulates in the through hole of base lower end, through equally distributed through hole, to cavity place, infrared sensor probe below, blow out, blow open and float near floating dust or the smog of infrared sensor probe.Air-flow continues input and blows out, and guarantees that infrared sensor probe is clean.
The infrared sensor protective device that the utility model provides; its base plate through holes is evenly arranged in the form of a ring; can realize the object that gas uniform distributes; greatly alleviate infrared probe and in the working environments such as dust, smog, caused the crystallization of dust, smog and the absorption of condensing, improved the detection accuracy of infrared sensor.
