Background

In the prior art, most dishes are cooked by heating edible oil to a high temperature and then frying, stir-frying, cooking and frying, the cooking habit can generate a large amount of water vapor and oil smoke along with the food making process, the oil smoke is condensed and then attached to the surfaces of solid bodies such as walls, air suction and exhaust equipment and the like and is difficult to clean, the surrounding environment is polluted, the original dynamic balance of an air wheel of the air exhaust equipment is destroyed, and the service life of the air exhaust equipment is shortened. In addition, the cooking oil generates oil smoke containing a large amount of organic chemicals such as benzene, aldehydes, ketones, hydrocarbons, fatty acids, alcohols, and the like. Among them, most substances are harmful to human body.

In order to clean up the oil smoke, a range hood appears in the prior art. However, the existing inertial interception equipment mainly adopts a barrier and an oil mist net cover to intercept waste gas and oil fume generated during cooking, then the waste gas and the oil fume are sucked into a cavity of the range hood, and a large amount of waste gas containing oil stain oil fume is discharged to the outside through the cavity of the range hood and a wind wheel.
