Background technique

At present, along with the raising of living standards of the people, range hood is extensive use, and people more and more pay attention to domestic environment and indoor air quality.But because the public flue of family kitchen that a variety of causes causes falls to distinguish the flavor of, the taint of odour phenomenon is still very general, fail effectively to be solved always, had a strong impact on resident's quality of life.Mounted anti-down cigarette device in the new residential building of paying, the complex structure that has is impracticable, and what have is poorly sealed, and effect is relatively poor.The illusory function that has, few of practical use; Deficiency in the anti-down cigarette device design has all directly influenced the air quality of household.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-down cigarette, anti-taint of odour, anti-wind, the non-return product of anti-down smoothly cigarette of discharging fume---the anti-down cigarette check valve of the plug-in type device of irritating.

The purpose of this utility model is achieved through the following technical solutions:

The anti-down cigarette check valve of a kind of plug-in type device comprises base, check valve, reducing three parts.Check valve one end is connected with base, and the other end is connected with reducing; Check valve is cylindrical, is constituted by valve body and air door, and the check valve inner chamber is equipped with a whole panel metal air door, and this air door is fixed in the valve body exhaust outlet by a positioning shaft, and air door can be done the opening and closing campaign around positioning shaft.

Base is made up of square plate and cylinder, the hollow shell-like that communicates before and after being, and there is a location sword groove that is used for determining installation direction the upper end of base inboard.

The hollow shell-like that reducing communicates before and after being, the reducing front end is connected with the heavy caliber airduct of range hood, and the end that reducing rear end and check valve do not have a sword groove is faucet type and is connected.

Be connected combination between check valve and the reducing, can be connected on the intake grill of check valve by reduction center, promptly the reducing rear end is faucet type with no sword groove one end of check valve and is connected; Also can respectively be plugged with a reducing at the two ends of check valve.

The anti-down cigarette check valve of plug-in type of the present utility model device, anti-down cigarette, anti-taint of odour, the anti-wind of irritating, it is smooth and easy to discharge fume.And easy for installation, to be convenient to clean, cost is lower, is easy to promote.
