 As shown in FIG. 1, the ozone generator of the present invention comprises a hollow tubular electrode 1, a conductive spring 2, an upper cylindrical member 3, a lower cylindrical member 4, a quartz tube 5 and a columnar electrode 6.

The above-mentioned tubular electrode 1 is made of a good conductor, and the conductive spring 2 connects a power source to the tubular electrode 1.

Above the upper cylindrical member 3, a rubber seal ring 31 and a coupling lid 32 are fitted and placed.

An insulating plug 51 is fitted into the opening of the quartz tube 5, and a single conductive guide rod 61 connected to a power source is passed through the insulating plug 51.

On the outer circumference of the upper stage of the upper cylindrical member 3, one air inlet pipe 33 communicating with the central hole of the upper cylindrical member 3 is provided, and the lower cylindrical member 4 has a closed bottom cylindrical body, An air supply branch pipe 41 communicating with the inside is provided, and a positioning seat 42 that projects annularly and is used for positioning the columnar electrode 6 is provided on the inner bottom surface of the lower cylindrical member 4.

The columnar electrode 6 is formed by forming a good conductor into a columnar shape, and the thread-shaped protrusions 62 are provided on the entire outer periphery thereof and are distributed in a spiral shape.

FIG. 2 shows a state after the above-mentioned components are combined. The conductive spring 2 is installed on the outer circumference of the tubular electrode 1 and is connected to the power supply line 71. The upper part of the tubular electrode 1 is closely fitted in the upper cylindrical member 3, and the lower part of the tubular electrode 1 is inside the lower cylindrical member 4. The tubular electrode 1 and the upper cylindrical member 3 and the lower cylindrical member 4 are connected to be integrated with each other, and the quartz tube 5 and other members to be described later are placed in the center of the tubular electrode 1 and the air inlet tube 33. Is used to draw in clean and dry air, which is subjected to electric shock to contain ozone, and is then sent to the outside via the air supply branch pipe 41.

A columnar electrode 6 is placed in the quartz tube 5, and an upper part of the quartz tube 5 is sealed with an insulating plug 51, so that the columnar electrode 6 is in a stable state. One conductive screw rod 61 penetrating the insulating plug 51 is inserted above the columnar electrode 6, and the conductive screw rod 61 is connected to the power supply line 72. The threaded projection 62 of the columnar electrode 6 is very close to the inner tube wall of the English tube 5.

In the above-mentioned device, the distance between each protrusion 62 of the columnar electrode 6 and the inner wall of the tubular electrode 1 is substantially the same, that is, the discharge position between the tubular electrode 1 and the columnar electrode 6 is substantially the same. Since the air is distributed at intervals, the air in the gap 8 (see FIG. 3) between the inner wall of the columnar electrode 6 and the outer wall of the quartz tube 5 of the projection 62 receives an electric shock and a part of the air is converted into ozone (a known technique).

In summary, the feature of the present invention is that the spiral projection 62 provided on the outer periphery of the columnar electrode 6 serves as a discharge area to stabilize the discharge.

Further, the protrusions 62 on the outer periphery of the columnar electrode 6 of the present invention may be provided in a plurality of ring-shaped nodules (see FIG. 4), in which case the ring-shaped protrusions 62 serve as discharge sections, The distribution of and the gap 8 are also easily determined by this.

[Effect of the invention]

 The present invention has the following excellent points. 1. Since the screw-shaped protrusion on the outer circumference of one electrode is located at the discharge position, the discharge area is evenly distributed, and stable control is performed for the distance of each discharge area. Highly effective. 2. Easy to set the distance between both poles. 3. Since the discharge sections are evenly distributed, overheating is unlikely to occur at any one point. 4. The circulating air containing ozone gas passes between the outer circumference of the quartz tube and the tube wall of the tubular electrode, that is, because both sides of the air passage are smooth walls, the air passes smoothly and stays. do not do. 5. Since the discharge position and distance are both effectively controlled, the efficiency is high and the best discharge effect can be obtained. 6. When air is drawn in, if the air is first passed through a ceramic tube having a filtering and dehumidifying function to keep the air clean and dry (known technology), the efficiency is further enhanced and the service life is extended. 7. It is easy to assemble, advantageous for production, easy to control quality, and easy to achieve the effect of ozone generation.
