[0002]

2. Description of the Related Art A conventional ozone generator generates ozone mainly by a combination of a ceramic electrode and a tungsten wire electrode, and discharges ozone using an electric fan.

[0003]

In the conventional ozone generator, it was essential to use an electric fan to flow and diffuse ozone. For this reason, it has been necessary to take measures against the increase in the number of parts and noise generated by the motor.

[0004] Further, since the structure of the ceramic electrode is complicated, there is another problem that the manufacturing cost such as the cost for the mold is high.

Further, in order to increase or decrease the amount of generated ozone, it is necessary to increase or decrease the size of the ceramic electrode and lengthen or shorten the length of the tungsten electrode wire.
It was almost impossible to adjust the amount of ozone after assembly.

In addition, if the device is used for a long time, dust adheres to the electrode and the amount of ozone generated decreases, so it is necessary to remove the dust. In the conventional device, however, the user needs to remove the dust. There was a problem that no countermeasures were taken.

An object of the present invention is to provide an ozone generator which can adjust the amount of generated ozone and remove dust without using a blower such as an electric fan and at low cost.

[0008]

The ozone generator according to the present invention is characterized in that a high DC voltage is applied between a discharge electrode comprising a cylindrical electrode and a needle electrode arranged near one opening of the cylindrical electrode. The application allows ions and ozone air to flow out from the other opening of the cylindrical electrode, and a cartridge detachably attached to a case containing the discharge electrode and the high-pressure generator is provided. The cylindrical electrode is disposed therein. It is characterized by being provided.

[0009]

In the ozone generator of the present invention, a high voltage is applied to a discharge electrode consisting of a cylindrical electrode and a needle electrode, whereby the inside of the cylindrical electrode is charged. An air current containing ions and ozone is generated in the electrode. The ions and ozone air are used as they are to flow out of the opening of the cylindrical electrode to generate and diffuse negative ions and ozone.

Further, by mounting the cylindrical electrode in a detachable cartridge, the cylindrical electrode can be easily taken out of the case.

Further, by providing a fragrance introducing member for guiding the fragrance into the cylindrical electrode, the fragrance emitted from the fragrance guided into the cylindrical electrode flows out to the outside together with the above-mentioned wind, and is deodorized by ozone and the fragrance is removed. discharge.
