Description
[ technical field ] A method for producing a semiconductor device
The application relates to tobacco pipe base field especially relates to the smoke ventilator field.
[ background ] A method for producing a semiconductor device
At present, a check valve composed of two semicircular valve plates is generally arranged on a smoke tube base on the market. When the fan of the range hood operates, the valve plate is blown open by the airflow generated by the fan, the airflow pipeline of the smoke tube base is smooth, and oil smoke is discharged along with the airflow. When the fan of the range hood stops operating, the valve plates reset under the action of self gravity, the two semicircular valve plates are closed, and the airflow pipeline of the smoke pipe base is closed, so that the oil smoke in the public flue is prevented from flowing back to the kitchen. However, since the valve plate is in direct contact with the oil smoke for a long time, grease is easily attached to the valve plate and cannot be smoothly opened, which affects normal smoke discharge. Moreover, after the valve plate is adhered with grease, the valve plate can not be completely reset when the fan of the range hood stops running, so that an airflow pipeline of the smoke pipe base can not be completely closed, and the oil smoke in the public smoke channel can be caused to flow backwards. Therefore, the service life of the existing check valve is very limited, and the check valve needs to be cleaned or replaced in time after being used for a certain time. In addition, the valve plate of the existing check valve is always opened automatically due to the air pressure generated in the public flue, so that the oil smoke in the public flue flows backwards.
Unless otherwise supported by sufficient evidence, the prior art described herein is not meant to be an admission that such prior art is widely known to those of ordinary skill in the art to which this application pertains prior to the filing date of the present application.
