Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector that collects dust by using static electricity.

[0002]

2. Description of the Related Art As a conventional dust collector using static electricity, a dust collector in which fibers or plastic filaments made of a material which is easily charged with static electricity is bundled is attached to a plastic handle. Such a dust collector has a function of charging the dust collector and adsorbing dust by friction between the dust collector and the surface to be cleaned during use.

[0003]

In most of the conventional dust collectors, the material of the dust collector and the material of the surface to be cleaned are not sufficiently separated in the Faraday charging line.
There was a problem that sufficient static electricity could not be obtained.

Further, the frictional static electricity cannot obtain sufficient electricity unless it is rubbed considerably strongly, and since it is a very slight friction in ordinary cleaning, a sufficient adsorption force for practical use cannot be obtained. on the other hand,
The vacuum cleaner has a problem that a sufficient suction force cannot be obtained even with a dry battery, the power consumption is large, and the noise is large. An object of the present invention is to solve the above problems and to provide an electrostatic precipitator having a strong dust collecting force on any surface to be cleaned.

[0005]

The present invention provides an electrostatic precipitator utilizing static electricity, which is provided with a gripping part, a dust collecting part, and a high-voltage generating part, and which is disposed on the gripping part and the dust collecting part side. An electrostatic precipitator, characterized in that the high voltage generating part and both electrodes of the high voltage electrode are electrically connected.

[0006]

According to the electrostatic precipitator of the present invention, high-voltage electricity generated in the high-voltage generating section is applied to the dielectric poles arranged on the gripping section and the dust collecting section side, and electrostatically induced to collect with the gripping section. A high voltage is induced between the dust parts. Since the gripping portion is held at the ground potential by the human body, a high voltage is maintained in the dust collecting portion and a dust suction force can be generated.

[0007]

EXAMPLE A first example will be described with reference to FIG. 1 is a dust collector of the present invention. Reference numeral 2 is a gripping portion, and 3 is a dust collecting portion. The grip portion 2 is composed of a container 20 made of an insulating material such as plastic, and a dielectric pole 8 made of a good electrical conductor is arranged on the inner surface thereof.

In the dust collecting portion 3, the core portion 10 is made of an insulator,
Inside it a dielectric pole 9 made of a conductor is arranged.
A battery 4 and a high voltage generator 5 are provided inside the container 20, and switches 6 and 38 are provided on the surface. For the dielectric poles 8 and 9,
The high voltage electrode of the high voltage generator 5 is connected via a switch 38. The core portion 10 of the dust collecting portion 3 is covered with a plastic or fiber bag body 13 in which a dust collecting body 12 made of a bundle of plastic filaments or fibers is implanted. By using the bag body 13, replacement work of the dust collecting body 12 can be facilitated.

When a high voltage is applied to the dielectric poles 8 and 9, a high voltage is induced in the dust collector 3 by electrostatic induction, and the dust collector 1
2 is charged with a high voltage and can adsorb dust. Since the grip portion 2 is held by a person's hand, the potential is held at a low potential near the ground potential.

FIG. 2 is a circuit diagram of this embodiment. Reference numeral 31 denotes an oscillating unit, which constitutes an oscillating circuit using the transistor 32, the transformer 33, and the resistor 34. The DC voltage of the battery 4 is converted into an alternating current, and at the same time, the transformer 33 boosts the voltage in proportion to the number of turns of the coil. Reference numeral 35 is a booster circuit including a diode 36 and a capacitor 37. This booster circuit is N
If it is composed of stages, the output of the transformer can be boosted N times.

The switch 38 is interlocked with the switch 6, the power is turned on at the position c, a high voltage is applied between the dielectric electrodes 8 and 9, and dust is absorbed. At the position b, the power is turned off, but the electric charge accumulated in the capacitor 37 leaves a potential difference between the dielectric electrodes 8 and 9, and the dust absorption state is maintained.
At the position a, the dielectric poles 8 and 9 are short-circuited, so that the potential difference becomes 0 and the dust suction action disappears. That is, this switch can freely control the adsorption and release of dust. In particular, at the position b, the dust absorption state can be maintained for a while with the power turned off, and the battery consumption can be reduced.

Since the outer periphery of this electrostatic precipitator is made of an insulating material, there is no danger to the human body such as an electric shock. Even if electricity leaks to the outside due to a breakdown of the container, etc., if both poles fail at the same time, electricity will not flow to the human body and no shock will be felt. In the case where both electrodes fail at the same time, it is expected that the high voltage generation mechanism itself will be destroyed, and it can be said that there is no danger.
Even in the worst case, since the electric current is weak, there is no danger of injuring the human body.

FIG. 3 shows another embodiment of the motor 40.
Friction body 4 in contact with the disc 42 connected to the shaft 41 of the
3, the triboelectricity is generated to form a high voltage generating portion.

[0014]

According to the present invention, an electrostatic precipitator having a strong dust collecting effect can be provided. Switch O
By turning the switch N and OFF, it is possible to freely control the adsorption and release of dust, and it is now possible to easily open the dust that has been adsorbed by cleaning in the trash box. or,
Compared with a vacuum cleaner, it has the advantage of less power consumption and no noise.
