Abstract

The invention discloses an air supply device based on centrifugal cut-off. The air supply device comprises an air supply pipeline and a centrifugal cut-off device, wherein the centrifugal cut-off device is arranged in the air supply pipeline, and the centrifugal cut-off device is used for cutting off or opening the air supply pipeline; and the centrifugal cut-off device comprises a centrifugal cut-off disc, a return mechanism and a delay trigger mechanism, the centrifugal cut-off disc is transversely arranged in the air supply pipeline, a plurality of first sliding ways distributed in a radial direction are arranged on the centrifugal cut-off disc in the circumferential direction, a centrifugal cut-off plate is arranged in each first sliding way, through hole flow channels are formed in the far ends of the first sliding ways, the return mechanism is arranged at the rotating center of the centrifugal cut-off disc and connected with the centrifugal cut-off plates, and the delay trigger mechanism is arranged on the centrifugal cut-off disc and connected with the return mechanism. The air supply pipeline is cut off and opened, the airflow uniformity is improved, and a vortex ring generation effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of fluid mechanics, in particular to an air supply device based on centrifugal cut-off. Background technique [0002] The existing vortex ring generating device often needs to set at least two power sources of the fan and the motor, and the structure is relatively complicated. Therefore, the present invention provides an integrated structure design, which can make it relatively simple to use when there is only one power source. The unique mechanism realizes the whole set of motion to generate the vortex ring. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air supply device based on centrifugal cut-off to realize the cut-off and opening of the air supply duct, improve the uniformity of the air flow, and enhance the generation effect of the vortex ring in view of the above-mentioned defects in the prior art. . [0004] The technical scheme th...
