Specific embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in the utility model embodiment
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
As shown in Figure 1 to Figure 3, a kind of active suction-type flammable explosive gas detection means air channel of the utility model embodiment
Structure, including vertical cabinet 1 and drawing fan, the upper surface of vertical cabinet 1 are inclined plane, and the centre of inclined plane has an inlet air
Mouth 2；Drawing fan is fixedly mounted in air intake vent 2；The side plate upper end of the arranged on left and right sides of vertical cabinet 1 has some through holes 4,
Lower end is provided with air outlet 7；The front panel upper inside wall level of vertical cabinet 1 is provided with a baffle plate 5；The rear board of vertical cabinet 1
Inclined on inwall and be provided with a guide vanes 6, and guide vanes 6 are located at the lower section of baffle plate 5.
Drawing fan includes fan shroud 301 and drawing fan body 302；Fan shroud 301 is fixedly connected on air intake vent 2；
