Operation principle: core of the present utility model is signal circuit, single chip machine controlling circuit, first, second circuit for power conversion, first, second ultrasonic transmitter, because it is especially big that power is done, make high power device in high pressure (300V), big electric current (20A) permanent load work again, do not generate heat, admittedly adopt double circuit conversion work method, i.e. one tunnel work, have a rest and cool off in another road, after first via work, single-chip microcomputer issues instructions to gate circuit in the single chip machine controlling circuit, and gate circuit makes signal forward the second the tunnel to from the first via.Realized circuit conversion work.

Utilize strong radiofrequency field that several physical actions are taken place medium, become dirty material under the radiofrequency field effect, a series of variations take place in its physics and thing univoltine matter, thereby causing into dirty material comes off, be dispersed into the smalls shape, form loose and deposit that be difficult for hardening, it mainly acts on and showing as:

Destroyed the condition that dirty thing generates and hardens on wall, made into dirty thing and in solution, form the dirty crystallization that disperses, and no longer on wall, form hard scale.

The cavitation of radio-frequency drive convection cell, make liquid produce a large amount of holes and bubble, when the gentle follicular rupture in hole, produce powerful pressure spike in certain limit, it not only can make into dirty material and form little dirty agglomerate tabling power fast in liquid, and can also cause established hard scale fragmentation.

Advantage of the present utility model:

1, first circuit for power conversion, second circuit for power conversion have adopted the high power module IGBT module of Japanese import, its electric current can reach 100A, voltage is 1200V, the ultrasonic power generator that is used for the 5KW level, more than required electric current and the voltage surplus capacity 5 times, caloric value reduces greatly when so just making this crucial high power device work, and the high power device surface temperature has only 20 ℃.And prior art adopts the single tube low-power device, and when with the 2KW level, the temperature of device surface can reach 60 ℃～70 ℃ during work.

2, first output-stage circuit of the present utility model and second output-stage circuit adopt E type ferrite iron core, and its magnetic circuit is closed, and metal is not acted on by or not magnetic field on every side, and the line bag does not generate heat, and guarantee to be operated in optimum state, and adjustment of inductance is also very convenient.What prior art adopted is straight bar type magnetic core, outer coiling, and the magnetic line of force is space radiation towards periphery, and the metal around making produces eddy current, coil heating.

3, instrument ventilates, and heat radiation is good, and is rational in infrastructure, cheap.
