The utility model is using the above structure, reasonable in design, by the air bag of setting and mutually matched rotating ring and
Stationary ring and the through-hole being arranged on stationary ring and the circular hole being arranged on rotating ring, three hole outlets can form sound wave superposition, effectively protect
Hinder operating pressure, and greatly reduce sound attenuating, the frequency surface of covering is narrow, reduces frequency, improves acoustical power, saves into
This.
Detailed description of the invention:
Fig. 1 is the configuration schematic diagram of the utility model.
In figure: 1, air bag, 2, inlet flange, 3, built-in motor, 4, output shaft, 5, stationary ring, 6, rotating ring, 7, through-hole, 8, go out
Gas flange, 9, circular hole, 10, axis, 11, gasket, 12, keyway, 13, bearing.
Specific embodiment:
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in fig. 1, a kind of air swirl formula sonic generator, including an air bag 1 are set in the rear end end of air bag 1
There is an inlet flange 2, a built-in motor 3 is equipped in air bag 1, the output shaft 4 of built-in motor 3 passes through after being pierced by 1 front end of air bag
One stationary ring 5 is connected with one with the rotating ring 6 that stationary ring 5 matches, and the circumferencial direction on stationary ring 5 along stationary ring 5 is equipped at intervals with several
Through-hole 7 is connected, if the circumferencial direction on rotating ring 6 along rotating ring 6 is equipped at intervals with an outlet flange 8 in the forward end of stationary ring 5
The dry circular hole 9 matched respectively with through-hole 7.
The output shaft 4 of built-in motor 3 is connected after being pierced by 1 front end of air bag with one end of an axis 10, and the other end of axis 10 passes through
It is connected after stationary ring 5 with rotating ring 6.
The air bag 1 is tube type air sack 1；The installation built-in motor 3 and its mechanical structured member that can be convenient, can use capsule
Interior compressed air radiates to built-in motor 3 reduces 3 thermal component of built-in motor, reduces built-in motor 3 and overheats caused failure, together
