System for generating aqueous ozone solution with variably controlled ozone generator and pipe assembly for in-line mixing

A system for generating aqueous ozone solution, comprising:

• an ozone generator;
• a relay configured to selectively activate the ozone generator by supplying an electrical current to the ozone generator;
• a variable resistor for controlling the rate of ozone output from the ozone generator by adjusting the electrical current supplied to the ozone generator from the relay;
• and
• a plurality of pipe assemblies, each of the pipe assemblies comprising:
• a first flow path for water to flow through, the first flow path including one or more ozone intake ports, the one or more ozone intake ports being fluidically coupled to the ozone generator, wherein the first flow path is defined by a first set of pipe segments and fittings between a water input port and a water output port;
• a second flow path fluidically coupled in parallel with the first flow path, the second flow path including a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path to produce an aqueous ozone solution, wherein the second flow path is defined by a second set of pipe segments and fittings that form a D shaped branch out of the first flow path;
• and
• a third flow path fluidically coupled in parallel with the first and second flow paths, wherein the third flow path includes a flow switch configured to transmit one or more control signals to the relay in response to sensing a flow of water, the relay being configured to supply the electrical current to the ozone generator in response to the one or more control signals.
