An electrical discharge ozone generation cell has first and second electrode base plates which are separated by a nonconductive flat spacer plate. Within a central opening in the spacer plate is fitted an electrode plate in close contact with the first electrode base plate. A dielectric plate in close contact with the second electrode base plate and with the spacer plate helps define a gas discharge chamber with the interior edges of the spacer plate and the electrode plate. Gaskets on the two sides of the spacer plate around the central opening displaced away from the interior edges of the spacer plate ensure a gas seal for the electrical discharge chamber.

The present invention generally includes an ozone generation system with a power supply that measures the rate of energy delivered to the ozone generation cell. While changing voltage, frequency or current will likely affect the rate of energy delivery, current, frequency and voltage provide a very poor and unreliable control for an ozone generation cell. It is only through control of the rate of energy delivery that consistent, reliable ozone generation is possible. Based upon the measurements of the rate of energy delivery as measured at the ozone generation cell, compared to the rate of energy delivery supplied, the rate of energy delivery supplied can be adjusted to improve ozone production and control.

A disinfection system includes an ozone water generator and a top seat. A base of the top seat has a top seat entrance and a top seat exit. A middle portion of an underside of the base is formed with an opening having a top seat inlet and a top seat outlet to communicate with the top seat entrance and the top seat exit. A power interface is provided on an outer cover of the top seat. Generator claws are interlocked with top seat claws. A generator mouth at a middle portion of the upper end of the ozone water generator is inserted into the opening. The generator mouth is formed with a generator inlet and a generator outlet to communicate with the top seat inlet and the top seat outlet. An anode and a cathode of the ozone water generator are movably connected to the generator control board through wires. The disinfection system is able to avoid unnecessary waste and improve convenience of use.

A smart toilet and an ozone assembly thereof are provided. The ozone assembly is provided for being connected to a water pipe of a water spraying assembly. The ozone assembly includes an ozone electrolyzer for being assembled to the water pipe and an ozone circuit module that is electrically coupled to the ozone electrolyzer. The ozone electrolyzer is configured to generate an ozone gas to be mixed into the water transported toward the water spraying assembly so as to form ozone water. The ozone electrolyzer is configured to maintain an ozone concentration of the ozone water to be within a range from 0.05 ppm to 0.3 ppm. The ozone circuit module is configured to drive the ozone electrolyzer while the water spraying assembly performs a water drawing process.
