Abstract

An atomization device 1 comprises a casing 2, a rotor 3 disposed rotatably with respect to the casing 2, and a stator 4 disposed on the same axis line with the rotor 3. The rotor 3 includes a first rotor cylinder portion 33 and a second rotor cylinder portion 34 which have a plurality of through-holes provided in peripheral walls thereof and which are disposed concentrically. The stator 4 includes a main-stator cylinder portion 42 and an inside sub-stator cylinder portion 43 which have a plurality of through-holes provided in peripheral walls thereof and which are disposed concentrically. The rotor 3 is fixedly positioned with respect to the casing 2. The stator 4 is movable by a lifting/lowering means 7 in the axial line L direction.

First claim

The invention claimed is:

1. An atomization device comprising:
a casing;
a rotor disposed rotatably with respect to the casing; and
a stator disposed on the same axis line with the rotor,
wherein:
the rotor has a plurality of concentrically disposed rotor cylinder portions each having a plurality of through-holes provided in a peripheral wall thereof;
the stator has at least one main-stator cylinder portion which has a plurality of through-holes provided in a peripheral wall thereof and which is inserted between rotor cylinder portions adjacent to each other; and
the rotor and the stator are relatively movable along the axial line direction, wherein
the rotor is fixedly positioned with respect to the casing, and
the stator is movable by a lifting/lowering means along the axial line direction.

2. The atomization device according to claim 1 , wherein the stator further includes an inside sub-stator cylinder portion which is disposed inside a rotor cylinder portion positioned on an inner-most side radially among the plurality of rotor cylinder portions, and which has a plurality of through-holes provided in a peripheral wall thereof.

3. The atomization device according to claim 1 , wherein the stator further includes an outside sub-stator cylinder portion which is disposed outside a rotor cylinder portion positioned on an outer-most side radially among the plurality of rotor cylinder portions, and which has a plurality of through-holes provided in a peripheral wall thereof.

4. The atomization device according to claim 1 , wherein the stator is movable such that a lower end of the main-stator cylinder portion is positioned above an upper end of the rotor cylinder portions.

5. The atomization device according to claim 1 , wherein the stator further includes a link portion formed integrally with the main-stator cylinder portion and linked with the lifting/lowering means.

6. The atomization device according to claim 1 , wherein the casing is a tank with an upper opening,
the atomization device further including a rotary blade which is disposed between a bottom portion of the casing and the rotor and which rotates as the rotor rotates.
