In addition, during the frequency lock time of the control board, if the liquid condition has low temperature, shaking and other changes that hinder cavitation, the ultrasonic module will not be able to output stable cavitation effects for a long time (usually more than 1min).

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] A cavitation quick start operation method, comprising the following steps:
[0020] Step 1: Place the power ultrasonic probe in the liquid;
[0021] Step 2: Turn on the ultrasound for a specific period of time according to the specified power;
[0022] Step 3: Turn off the ultrasound and pull out the ultrasound probe from the liquid;
[0023] Specifically: before the ultrasonic module is inserted into the liquid surface, the ultrasonic module is first turned on in the air, and the control board is frequency-locked for a period of time until it can work stably at the natural frequency in the air, and then the ultrasonic module is inserted into the designated position on the liquid surface In order to prevent the splashing of the liquid surface when the ultrasonic module is inserted into the liquid surface, it is controlled at a lower amplitude in the air, and i...

The invention belongs to the technical field of ultrasound, and particularly relates to a quick starting operation method for cavitation. The method comprises the following steps: 1, placing a power ultrasonic probe in liquid; 2, starting ultrasonic treatment for a specific period of time according to specified power; and 3, closing the ultrasound and pulling out the ultrasonic probe from the liquid. Concretely, before an ultrasonic module is inserted into the liquid level, ultrasonic waves are started in the air firstly, a control board card conducts frequency locking for a period of time till the control board card can stably work in the air according to the inherent frequency, and then the ultrasonic module is inserted into the designated position of the liquid level to act; in order toprevent liquid level splashing caused when the ultrasonic module is inserted into the liquid level, the ultrasonic module is controlled in the air at a low amplitude, and the ultrasonic module is output at a high amplitude meeting the use condition after being inserted into the liquid level. According to the invention, the ultrasonic module can quickly generate a cavitation effect in the acted liquid, so that a better acting effect can be generated within limited acting time.
Description
technical field [0001] The invention belongs to the field of ultrasonic technology, and in particular relates to a cavitation quick start operation method. Background technique [0002] Power ultrasound can stably generate cavitation bubbles in a liquid environment. When the cavitation bubble explodes, it will generate instantaneous high pressure locally, accompanied by light emission and heat release. In the field of life sciences, cavitation effects can be used for cell disruption, thrombus therapy and surgical hemostasis; in chemistry, cavitation effects can also be used for wastewater treatment, chemical catalysis and surface cleaning. [0003] The sound energy output by the ultrasonic module is converted from the electric energy in the control board through the piezoelectric ceramic transducer. In actual use, the control board often locks the output frequency to the natural frequency of the transducer in the form of frequency locking to achieve the highest output effi...
