As the motor speed increases, the pulses that impact the bubbles on the treatment instrument also increase, thereby enabling adjustment of the pulse frequency.
The working process of the invention is as follows:
an instrument to be processed is placed on the upper portion of a supporting block of the bubble covering and extinguishing frame, a rotating motor drives a rotating paddle in work, and liquid pressure on the lower portion of the paddle is low in the rotating process, so that bubbles are generated (the principle is equal to the cavitation process of an impeller machine). The bubbles leave the paddle and move upwards to enter the micro-channel of the bubble covering and extinguishing frame, and in the process of moving upwards from the lower part of the channel, because the interface of the channel becomes small, the volume of the bubbles extruded becomes small, the internal pressure increases, and the bubbles are broken and extinguished at the outlet of the micro-channel. The bubbles are broken to generate vibration, and the impact wave of the vibration acts on the instrument on the upper part of the supporting block, so that the vibration is generated. Along with the change of the rotating speed of the motor, the frequency of the bubbles acting on the instrument is changed, so that the adjustment of the vibration frequency is realized.
Compared with the prior art, the invention has the following advantages: the structure is simple, low-frequency oscillation can be generated, and the oscillation frequency can be adjusted within a large range.
