Also cross the center of rotating circular disk and fixed disc, the center of rotating circular disk is fixed in connecting shaft connecting shaft,
Bearing is equipped between the center and connecting shaft of fixed disc.
It is connected with an air gauge in the front and rear of ontology.
The front of ontology is pre-small post-large taper, and rear portion is cylinder, which further increases the effect of exciting.
Ten fan-shaped slot holes are uniformly provided on rotating circular disk, the central angle a of fan-shaped slot hole is 18 °, that is, when rotational circle spirals
It circles, 10 openings is just completed between plenum chamber and low-pressure chamber and are closed, to make spout air-flow cause to pulse.
The beneficial effects of the invention are as follows：
Intrinsic gas chamber has been divided into low-pressure chamber and plenum chamber by disc assembly in the present invention, and fixed disc and
The design of several sector slot holes makes rotating circular disk after rotating a circle on rotating circular disk, can be complete between plenum chamber and low-pressure chamber
At multiple open and closure, spout air-flow is set to cause to pulse, so that exciting range is big, exciting force is big, it is sufficient to meet various scientific researches
Oscillation intensity needs.
Description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
