Description

But wireless remote control's from open-close type contrary air door that ends

Technical Field

The utility model relates to a wireless remote control self-opening and self-closing type check air door.

Background

The check valve is a device used at the joint of the exhaust duct and the flue of the range hood, and is used for exhausting the oil smoke of the range hood and preventing the oil smoke in the flue from returning to the range hood. The existing check valves are divided into gravity type and spring type. The gravity type is that the non-return sheet is closed under the action of gravity when the cigarette machine is not opened. When the cigarette machine is opened, the generated air flow pushes the non-return sheet away, so that the oil smoke air is discharged. The spring type is that the check sheet closes the valve sheet under the action of the spring when the cigarette machine is not opened. When the cigarette machine is opened, the generated air flow pushes the non-return sheet away to remove oil smoke and air. However, both types of check valves have the following problems: the valve plate can not be completely opened: because the opening of the smoke exhaust ventilator is realized by relying on the principle that air pressure overcomes gravity or spring force, the valve plates cannot be completely opened when the smoke exhaust ventilator works, and the smoke exhaust ventilator cannot be completely opened to discharge smoke. And the motor of the cigarette machine needs to do certain work for opening the valve plate, so that energy waste is caused to a certain degree. After the check valve is used for a certain time, the oil smoke on the check valve can block the closing of the valve plate, so that the check effect of the check valve is poor; (II) installation and wiring problems: the distance between the range hood and the flue can be adjusted according to the actual installation environment, but if the distance is long, the problem of inconvenient wiring exists, and the use of the check valve can be influenced.
