Electrolytic Ozone Generator

Abstract

An electrolytic ozone generator comprises a cavity, and electrodes and a membrane disposed in the cavity. The electrodes comprise an anode and a cathode. A water inlet and a water outlet are formed in two ends of the cavity respectively. The membrane has a side face parallel and opposite to the anode and a side face parallel and opposite to the cathode. An annular guide channel is formed between a periphery of the anode, the cathode and the membrane, and an inner wall of the cavity. A water distribution space is formed between the water inlet and the electrode at the water inlet end, and is communicated with the annular guide channel and the through holes in the electrode at the water inlet end. The anode and the cathode are electrically connected through water flowing therethrough. The ozone generator can increase the ozone concentration in water.
