Problems solved by technology

[0002] The fan system is used to convert mechanical energy into gas pressure energy and kinetic energy. Usually, the fan system is a cavity with an inlet and an outlet composed of a fan cover and other components. The design of the fan cover structure will directly affect the efficiency of the entire air duct system. , the windshield structure in the existing structure may generate a large backflow, causing a certain pressure relief, resulting in a large reduction in the conversion efficiency of the system

Abstract

The invention relates to the technical field of power transmission and discloses a fan system and an electric instrument. The fan system comprises a fan cover (10) and a movable impeller (20). The fan cover (10) is provided with an air inlet (11) and a ring-shaped groove (12) formed around the air inlet (11). The movable impeller (20) comprises a front cover plate (21). The front cover plate (21) is provided with a center through hole and bent upwards toward the center through hole from outside to inside. The top of the front cover plate (21) extends into the ring-shaped groove (12), and a gap is kept between the top of the front cover plate (21) and the side wall of the ring-shaped groove (12). The fan system is utilized and can prevent backflow from being generated in the fan cover structure, and thus pressure relief is prevented to improve efficiency of the system.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a fan system and electric appliances. Background technique [0002] The fan system is used to convert mechanical energy into gas pressure energy and kinetic energy. Usually, the fan system is a cavity with an inlet and an outlet composed of a fan cover and other components. The design of the fan cover structure will directly affect the efficiency of the entire air duct system. , the structure of the windshield in the existing structure may generate a large backflow, causing a certain pressure relief, resulting in a large reduction in the conversion efficiency of the system. Contents of the invention [0003] The purpose of the present invention is to solve the problem of backflow in the fan system fan system structure in the prior art, and provide a fan system that can prevent the backflow generated by the fan system. [0004] In order to achieve the above object, t...
