BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antistatic ion generator that prevents static electricity from damaging electronic parts and equipment.

0002

[Prior Art] Conventionally, various electronic components and devices themselves, or the factories where they are manufactured or the places where they are used, tend to generate static electricity or generate large amounts of static electricity depending on the surrounding environment. There were times when it became electrically charged. This charged static electricity may cause equipment to malfunction, or in some cases, a large amount of static electricity may flow instantaneously, damaging electronic components and equipment.

[0003] Therefore, in recent years, in factories that handle electronic parts and equipment, etc., ion generators (ionizers) that emit ions have been installed within the factory in order to gradually remove the charged electricity. It is being said.

[0004] This ion generator releases positive and negative ions by applying high positive and negative voltages to two discharge electrodes arranged at a predetermined distance, and the amount of each ion generated is controlled. By controlling it, it neutralizes the electric charge that has built up around electronic equipment and removes static electricity, and it is usually attached to the ceiling or wall of the room where work is performed.

[0005]

[Problems to be Solved by the Invention] However, in conventional ion generators installed in factories, etc., a power supply unit installed inside or outside the factory is connected via a high-voltage cable conduit installed inside the factory. Power was being supplied from.

[0006] For this reason, when it is desired to change the mounting position of an existing ion generator, it is necessary to replace the high-voltage cable conduit, which poses a problem that the work is complicated and expensive.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an antistatic ion generator that can be installed easily and at low cost.

[0008]

[Means for Solving the Problems] That is, the present invention has been made to achieve the above-mentioned object. The ion generator includes a box-shaped housing, an ion generator attached to the outer surface of the housing, and a high-voltage power supply built into the housing from a low-voltage indoor power source to the ion generator. The gist of the present invention is an antistatic ion generator characterized by being equipped with a high voltage power supply for performing the following steps.

[0009]

[Operation] In the present invention, an ion generator is attached to the outer surface of a box-shaped casing of an ion generator for static prevention, and high-voltage power to be supplied to the ion generator from a low-voltage indoor power supply is generated inside the casing. Since a high voltage power supply is provided, the antistatic ion generator can be used without installing high voltage cables within the factory.

The negative high voltage DC pulse is supplied to the ion generator 4b.

The power supply unit 11 also generates power to the controller 12 and fan motor 13 that control its operation. The controller 12 is given a signal from the sensor 6 that corresponds to the concentration of positive ions and negative ions. Based on the signal from the sensor 6, the controller 12 adjusts the levels of the positive high voltage DC pulse and the negative high voltage DC pulse supplied from the power supply unit 11 from kV to kV so that the ion concentration is set in advance.
Change within the range.

The transmitter 14 for remotely controlling the ion generator 1 includes a switch for turning on and off the power of the ion generator 1, a switch for starting and stopping the fan motor 13, and a switch for transmitting cations and anions. A key is provided for adjusting the amount of generation. Signals corresponding to the above-mentioned switch and key operations are transmitted from the transmitter 14 to the receiver 8.
