Plasma liquid generating device

A plasma liquid generating device, comprising:

• a tube having at least an air inlet and a flow channel outlet;
• a plasma generating module disposed adjacent to the air inlet and configured to ionize air outside the tube to form plasma;
• a flow limiting unit detachably disposed in the tube, wherein a distance between the flow limiting unit and the flow channel outlet is greater than a distance between the air inlet and the flow channel outlet, a water flow passes through the flow limiting unit so as to suck the plasma into the tube through the air inlet, the plasma is then mixed in the water flow, and the flow channel outlet of the tube is large enough for configuring the flow limiting unit;
• a position limiting member detachably disposed at the flow channel outlet to limit a position of the flow limiting unit;
• a hydroelectric generator for providing power to the plasma generating module;
• a driving circuit coupled with the plasma generating module and driving the plasma generating module to generate ozone and nitrate ions;
• a waterproof housing for accommodating the tube, the plasma generating module, the flow limiting unit, the position limiting member, the driving circuit, and the hydroelectric generator;
• and
• an adjust-controlling unit coupled with the driving circuit and controlling the driving circuit to control a generation proportion of the ozone and the nitrate ions generated by the plasma generating module;
• wherein the driving circuit outputs a driving voltage to the plasma generating module;
• when the driving voltage has a high frequency, the generated nitrate ions are more than the generated ozone in the generation proportion;
• and
• when the driving voltage has a low frequency, the generated ozone is more than the generated nitrate ions in the generation proportion.
