Problems solved by technology

[0002] The existing vortex ring generation device, after the airflow is accelerated by the fan, often sets up a mechanical device inside the pipeline to cut off the airflow to realize the pulse vortex ring. However, since the fan is always in a rotating state, excess gas will be generated every time it is cut off, causing blockage. Rear runner

Abstract

The invention discloses an elastic sensing type vortex ring exciter comprising a ventilation pipeline, a reducing nozzle, an axial flow fan, an elastic cut-off mechanism, a sensing mechanism and a locking mechanism, the axial flow fan and the elastic cut-off mechanism are sequentially arranged in the ventilation pipeline in the airflow flowing direction, and the reducing nozzle is arranged at an outlet of the ventilation pipeline. According to the elastic sensing type vortex ring exciter, a pulse vortex ring is realized, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of fluid mechanics, in particular to an elastic sensing type vortex ring exciter. Background technique [0002] The existing vortex ring generation device, after the airflow is accelerated by the fan, often sets up a mechanical device inside the pipeline to cut off the airflow to realize the pulse vortex ring. However, since the fan is always in a rotating state, excess gas will be generated every time it is cut off, causing blockage. rear runner. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elastic sensing type vortex ring exciter to realize pulsed vortex rings and reduce energy loss in view of the above-mentioned defects in the prior art. [0004] The technical scheme that the present invention adopts for solving the problems of the technologies described above is: [0005] An elastic sensing type vortex ring actuator, including a venti...
