Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a heating wind pressure detection device, includes casing 3 and wind pressure detection switch 9, its characterized in that, the horizontal end both sides of casing 3 communicate respectively has play tuber pipe 1 and air-supply line 2 to the casing 3 outside is provided with wind pressure detection switch 9, the inside of casing 3 is provided with the wind pressure with the laminating of air-supply line 2 and detects baffle 10, and the top welding that the wind pressure detected baffle 10 has the pivot 8 of being connected with casing 3 rotation, pivot 8 runs through casing 3 and extends to wind pressure detection switch 9 one side, and pivot 8 extends the end and closes soon and be connected with contact 12.
