ABSTRACT:
BACKGROUND OF INVENTION
Recently, hairdryers, hairbrushes, etc., with functions to expel ionized particles (negatively ionized air or positively ionized air) have enjoyed increasing popularity. These devices make it possible to obtain the effect of treating the hair, making it more manageable and giving it more body, by expelling towards the hair negatively ionized air or positively ionized air while drying the hair or brushing the hair.
In conventional hairdryers, etc., of the type described above, the effect of expelling negatively ionized air or positively ionized air at an object has been to create a static charge in the object due to the ionized particles expelled. The build up of this static charge presents a problem in that it prevents the treatment, described above, from being fully effective. For example, as shown in
FIG. 24
, when an object
3
becomes positively charged and negatively ionized particles generated by an ionized particle generator
2
strike the object
3
, the positive charges that have accumulated in the object
3
are neutralized by the negatively ionized particles
1
, reducing the electric potential V
1
as shown in FIG.
25
. After this, when the object
3
goes to a negative electric potential, the ionized particles
1
and the object
3
both have the same polarity, and thus repel each other, preventing the adsorption of the ionized particles. When, as is shown in
FIG. 26
, a negative charge has accumulated on the object
3
, the electric potential V
2
of the object
3
is the same as that of the ionized particles (as shown in FIG.
27
), so they repel each other, preventing adsorption. As shown in
FIGS. 28 through 31
, when positively ionized particles are used as the ionized particles
1
, the electric potential V
3
of the object
3
and the electric potential of the charged particle
1
are both reversed, and so, similarly, as time passes the electric potential V
4
of the object
3
(
FIG. 31
) goes to the same polarity as the ionized particles
1
, causing the ionized particles
1
and the object
3
to repel each other, preventing the ionized particles
1
from adsorbing. The result is that it has been difficult to cause the ionized particles
1
generated by the ionized particle generator
2
to be adsorbed continuously by the object
3
.
The present invention provides an ion application device and ion application method that is able to apply ionized particles continuously, able to cause a greater number of ionized particles to be attracted to the object, and able to cause these ionized particles to be adsorbed continuously by the object.
SUMMARY OF INVENTION
In general, in one aspect, the present invention relates to an apparatus for applying ionized particles. The apparatus comprises an ionized particle emitter for emitting generating ionized particles against an object, and an electric potential maintainer for maintaining electric potential of the object at a predetermined level such that the ionized particles emitted against the object by the ionized particle emitter are continuously attracted to the object while the electric potential is maintained.
