2. A device for controlling a dissolved amount of gas comprising:
an injection supply part arranged in an upper part of a closed tank and injecting pressurized fluid supplied from a hot water supply machine, a tap water system, or the like for mixing in a large amount of gas of a compressed state in the tank;
a liquid foam generating container part in which a diameter of an inner cross section of a container arranged in an upper part of the tank and, having an upward opening is reduced slightly in an upper part so that an uppermost part has a wide angled opening, through which the pressurized fluid injected from the injection supply part is received, said liquid foam generating container part being provided within the tank; and
a discharge rate controlling part which is attached downstream of the tank and controls a discharge rate of a solution or alternatively achieves constant rate discharge, thereby controls a pressure of the gas of the tank or maintains a constant pressure.
