Ozone water supply apparatus and ozone generation device

An ozone water supply apparatus and an ozone supply device are provided. The ozone generation device includes a Venturi tube and an ozone generation module connected to the Venturi tube. The ozone generation module includes a circuit unit, an ozone-activated tube, and a launcher, the latter two of which are electrically coupled to the circuit unit. The launcher includes a transparent tube, a floating body arranged in the transparent tube, and an optical detector arranged outside of the transparent tube and electrically coupled to the circuit unit. When a gas flows through the transparent tube so as to move the floating body along the transparent tube, the optical detector is configured to detect the movement of the floating body, so that the ozone-activated tube can be driven by the circuit unit to excite the gas to become an ozone that floats toward the Venturi tube.
