Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary ozone generator.

Conventional ozone generators are known to utilize flat plate electrodes or tubular electrodes in order to obtain the necessary corona discharge, and by passing air through the discharge space of these fixed electrodes, Converting the oxygen produced into ozone is being carried out. There are also devices in which one of the electrodes is configured to be movable and a discharge space is provided between the fixed electrode and the movable electrode.

The disadvantage of such conventional devices is that the smaller the devices, the more difficult it becomes to treat the air in their discharge space; Dust and moisture adhere to the electrode surface, and the hydrogen compounds formed thereby reduce the efficiency of ozone generation, which also causes unplanned current collection. It was impossible to obtain small devices.

The present invention was made to eliminate such drawbacks, and its structure will be explained with reference to the drawings.
Reference numeral 1 designates a motor, one of whose shafts 2 rotates a Shirotsko fan 3 and the other rotates a rotor 4 made of an insulator, and 5 a hood that surrounds the Shirotsko fan 3. The details of the rotor 4 are as shown in FIGS. 3 and 4, and the shaft 2 of the motor 1 is inserted and fixed from one end of the rotor 4 made of a cylindrical insulator along its rotational axis. In this embodiment, a cross-shaped power feeding surface 6 is fixed to the other end surface. The tip of each side 6' of the power feeding surface 6 extending in a cross shape is bent along the outer circumferential surface of the rotor 4 and fixed to the outer circumferential surface, and is connected to the four rotating electrodes 7 of the rotor 4.
form. 8 is an insulator that completely covers each rotating electrode 7 of the rotor 4. In this way, four rotating electrodes 7 covered with an insulator 8 are installed on the outer peripheral surface of the cylindrical rotor 4.

A cylindrical body 9 made of a cylindrical insulator is installed around the rotor 4 to surround the rotor 4, and fixed electrodes are provided on the inner peripheral surface of the body 9 facing the rotating electrode 7 of the rotor 4. 10 is installed, and its surface is covered with an insulating cylinder 11
covered with. Further, a fixed electrode terminal T protruding from the outer peripheral surface of the cylindrical body 9 is electrically connected to the fixed electrode 10.

Although both ends of the cylindrical body 9 are open,
Those open parts are a closing plate 12 and a lid body 1, respectively.
3 is fixed to the cylindrical body 9, thereby closing it. To explain these parts, the shaft 2 of the motor 1 passes through the closing plate 12 installed between the motor 1 and the rotor 4, and an exhaust pipe 14 is protruded from a part of the closing plate 12. 14 is the connecting tube 1
5 to the hood 5 of the Sirotskov fan 3. On the other hand, the lid body 13 fixed to the end of the cylinder body 9 facing the power supply part 6 of the rotor 4 has an intake cylinder 16 in a part thereof, and the lid body 13 is fixed to a substantially central part of the lid body 13. The power supply terminal t is electrically connected to the contact 17 via the spring S, and the contact 1
7 is brought into physical and electrical contact with approximately the center of the power supply section 6 under the action of a spring S.

Incidentally, the part indicated by the symbol O in FIG. 2 is an air outlet installed in the hood 5 of the Sirotskov fan 3. In addition, in the attached drawings, in order to avoid complexity, the wiring and switches necessary to operate the motor 1, and the wiring that should be connected to the fixed electrode terminal T and the power supply terminal t are omitted. ing.

Next, to explain the operation of the present invention configured as above, when a voltage required for discharge is applied between the fixed electrode terminal T and the power supply terminal T and the motor 1 is further rotated, the shaft The Sirotskov fan 3 and the rotor 4 fixed to the hood 2 start rotating, and the rotation of the former causes the air inside the device to be released to the outside from the air outlet O of the hood 5, thereby creating a negative pressure inside the device. As a result, external air is sucked into the device from the intake pipe 16 of the lid 13. Further, electric discharge occurs between the rotating electrode 7 of the rotor 4 and the fixed electrode 10 of the cylinder 9, and a large amount of ozone is generated in the air introduced into the apparatus from the intake cylinder 16 by the electric discharge.

In this case, the contact 17 installed on the lid 13 is pressed into contact with the center of the power supply part 6 of the rotor 4 by the action of the spring S, so even if the rotor 4 is rotated, the contact is always released. Therefore, the necessary voltage can be continuously supplied to the rotating electrode 7 of the rotor 4.

As described above, according to the present invention, the Sirotskov fan 3
Since forced air circulation is ensured, even if the interval between the rotating electrode 7 and the fixed electrode 10 is narrowed as desired, there is no problem with the air circulation between them, and the entire device can be adjusted to meet the requirements. It can be miniaturized, and the completed device consists of three parts: the part necessary for discharge, the part necessary for driving the device, and the part controlling air circulation, making it suitable for any purpose. It also has the effect of being completely compatible.
Furthermore, by predetermining the efficiency of the Sirotskov fan 3, the mixing ratio of ozone and air can be adjusted. coated, which eliminates the possibility of leaks and
Furthermore, by rotating one of the electrodes by the rotor 4, a more stable ozone generation space can be ensured.
