Abstract: A water heat source generator device, including an airtight water storage tank, a feeding structure linked to the water storage tank, and a guide-in structure connected to the water storage tank and the feeding structure. In which the water storage tank enables normal passing in and out of water, and the feeding structure enables water to be drawn from the water storage tank, before which the guide-in structure guides in hydrogen, oxygen or common air, and high speed rotation is used to cause friction between the gas and water to effect an approximately cavitation phenomenon, generating a heat source, which is carried to a decompression structure along with the water to produce microscopic water air bubbles, whereupon a burst temperature is generated when the air bubbles instantaneously burst, and the generated heat source diffuses into the water storage tank for continuous circulation thereof to achieve production of hot water.

Abstract: A bubble generator is constructed to include a cylindrical casing, a tapered tube suspended in a front open side of the casing and adapted for guiding water into the casing, the tapered tube having recessed holes on the inside adapted for causing a negative pressure when water passing through the tapered tube into the inside of the casing toward the water outlet, a rod member axially slidably inserted through a rear closed side of the casing into the inside of the tapered tube, and a stopper fixedly fastened to the rod member and moved with the rod member to adjust the gap between the stopper and the tapered tube.
