Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a static electricity erasing function that ejects ions and gas at the same time to neutralize and eliminate static electricity by the ions, and also blows off dust that has risen due to static electricity elimination by the gas. The present invention relates to a simple dust remover.

[0002]

2. Description of the Related Art Printing equipment, electronic equipment, optical equipment, medical equipment, various measuring equipment, and the like, which are made of many plastic materials, are easily charged with static electricity and cause various troubles. And this becomes more pronounced in the dry season. When static electricity is charged, dust is easily adsorbed, and once adsorbed, it does not easily fall off.

Under these circumstances, conventionally, an apparatus has been devised for ejecting ions and gas at the same time to erase static electricity and blow off dust.

[0004]

However, since the conventional device is a large-sized device using a compressor, and is bulky and heavy, it is inconvenient to carry and there is a problem that the place of use is limited. . Further, there is a problem that the manufacturing cost is high because of the large number of parts.

The present invention has been made in view of the above points, and it is small and lightweight, can be easily carried anywhere, and is simple in dust removal with an electrostatic elimination function, which is inexpensive in cost. It is intended to provide a device.

[0006]

The gist of the present invention is to provide a blow bomb filled with a dust blowing gas and a battery, and a power supply for supplying an electric current to an electrode in a blow gun described later. The current from the pack and the power pack is boosted and supplied to the electrodes to generate corona discharge at the electrodes to generate ions, and when a trigger is pulled, a gas containing ions is ejected from the injection port. A simple dust remover with an electrostatic erasing function, in which the blow cylinder is connected to the blow gun with a tube having a connecting coupler and the power pack is connected to the blow gun with a power cord.

Further, if the connecting coupler has a structure capable of pushing down and releasing the injection nozzle of the blow bomb, it is possible to eliminate the pressure load on the gas on-off valve in the blow gun when not in use. That is, if the strong pressure is constantly applied, the valve portion is likely to fail, but this can be solved.

Further, if a hook member for hanging the belt on the power pack is fixed and a means for detachably holding the blow cylinder is provided in the power pack, the power pack and the blow cylinder can be attached to the waist. Can be held. Therefore, it is easy to carry and does not feel heavy. In addition, you can use your hands freely, which will speed up your work.
