Abstract

The utility model provides a novel pneumatic impeller. The novel pneumatic impeller comprises a machine body, a wheel body, and blades. The blades are fixed on the wheel body which is fixed on a wheel shaft and arranged in a cavity of the machine body. A bearing is arranged in the wall of the machine body on the wheel shaft. Tongue pieces which are the same as the blades in width are arranged on sides of top edges of the blades in an anticlockwise mode. The tongue pieces are movably connected with the blades through movable shafts. Using the connecting shaft as an axis, the other edge of each tongue piece can move vertically within 90 degrees along the blade face of the other blade of adjacent blades. The blade face corresponding to the movable edge of each tongue piece is arc-shaped. When the tongue piece sliding edges are located at upper stopping points, the two adjacent blades, the wheel body, the tongue pieces, and the wall the cavity of the machine body form a relatively-sealed impeller hollow cavity. An annular air groove is formed in the side wall, corresponding to the bottom of the impeller hollow cavity, of the machine body. The annular air groove is communicated with an air inlet through an air passage and an air passage opening. A pressure control valve is arranged on the air passage. A cam shaft is arranged at the air inlet. The air inlet is communicated with an air inlet passage, and an exhaust port is communicated with an exhaust passage.
