The present invention is more advantage to, and more particularly, to continuously maintain the generation of ozone can be easily grasp the ozone generating unit lifetime, and the ozone generation amount, and easy replacement on the outside of the sterilization device to the appropriate time relates to an ozone generating apparatus Castle the present invention relates to an ozone generator to improve,
In particular, the present invention is to the front of the case body toward the interior ozone generating portion for emitting light and, installing the ozone generating portion passes through a life detection means detects the light to verify the ozone generating unit lifetime, and inside the body of forming an opening, and then, to install the Led circuit panels can be represented on the signal detected by the life detection means to the front inner side of the opening to the color, it can be fixed to the front side of the sterilization device to the front opening of the Led circuit panel and installing the front cover from the outside in, and then, the front cover having a Led display that can detect a Led light on the other hand, the first terminal for applying a power to the rear, the air pump of the case body in the ozone-generating unit and a second terminal portion for supplying power to each electronic circuit is characterized in that a possibly installed detachably with the power source connecting terminal of the sterilizing apparatus
