Abstract

The invention discloses an air volume regulation device for an exhaust fan. The air volume regulation device comprises an exhaust fan body with a side sealing cover, wherein an air inlet is formed in the side sealing cover, and is connected with an air inlet pipe; a throttle regulation piece is arranged on the air inlet. The air volume regulation device is characterized in that an air supplementation port is also formed in the side sealing cover, wherein the air supplementation port and an area between the air supplementation port and the air inlet are covered when the throttle regulation piece is positioned on the outermost side; the throttle regulation piece moves relative to the center of the air inlet to regulate the sizes of areas of the air inlet and the air supplementation port; the area of the corresponding air supplementation port is enlarged when the area of the air inlet is reduced, and is reduced when the area of the air inlet is enlarged, so that the total volume of air passing through an air outlet can be kept unchanged, and the exhaust fan is prevented from being overloaded and damaged by sharp changes in the volume of sucked air. The invention also discloses the exhaust fan employing the device and an organic matter degrader.

Description

technical field [0001] The invention relates to the technical field of an exhaust fan, in particular to an air volume regulating device for an exhaust fan. Background technique [0002] For the exhaust fan in the prior art, when the damper adjusting piece is adjusted, when the damper adjusting piece moves to the center, the amount of gas sucked into the body by the exhaust fan decreases, which easily leads to motor overload and damages the exhaust fan. Contents of the invention [0003] The present invention aims to solve the above problems to a certain extent, and at least provide a commercial application. [0004] For this reason, the purpose of the first invention of the present invention is to provide an air volume regulating device for an exhaust fan; the purpose of the second invention of the present invention is to provide an exhaust fan; the purpose of the third invention of the present invention is to provide an organic matter degradation machine. [0005] In ord...
