Hereinafter, the invention will be described with reference to embodiments, but the invention is not limited to the following.
(Embodiment 1)
<Structure>
The bubble generator 17a of the first embodiment will be described with reference to a cross-sectional view of FIG. 2 (a) and a plan view of FIG. 2 (b). The foam generator 17a includes a container 15, a rotating portion 30a, and a rotating mechanism 13.

<Rotating part 30a>
The rotating portion 30a is a rotating shaft that connects the first rotating portion 11, the bubble generating portion 14, the second rotating portion 12, the first rotating portion 11, the bubble generating portion 14, the second rotating portion 12, and the rotating mechanism 13. 16 and.
The first rotating portion 11 rotates to blow up the soapy water 20 upward to form the first bubble 21.
The bubble generating portion 14 is a thin plate having a through hole. The second bubble 22 is generated by passing the first bubble 21 through the through hole. It may be a slit instead of a through hole. All you need is a gap.
The second rotating portion 12 prevents the second bubble 22 from going upward. The second bubble 22 is held downward. The second bubble 22 that has advanced downward becomes the first bubble 21 again at the first rotating portion 11. By repeating this, a firm foam is generated.
The rotating shaft 16 connects the first rotating portion 11, the bubble generating portion 14, the second rotating portion 12, and the rotating mechanism 13. As a whole, it becomes the rotating portion 30a. The rotating shaft 16 is a central axis when the rotating portion 30a rotates. In this example, the bubble generating portion 14 covers the first rotating portion 11.

<Container 15>
Soap water 20 is put in the container 15. The container 15 has a cylindrical shape. Inside the container 15, the rotating portion 30a rotates to generate bubbles.
<Rotation mechanism 13>
The rotation mechanism 13 is an activation unit that rotates the rotation shaft 16 of the rotation unit 30a. You may rotate it manually. Alternatively, it may be rotated by a motor or the like.

<Process>
(1) Put soapy water 20 in the container 15.
(2) Put the rotating portion 30a into the container 15.
(3) The rotating mechanism 13 rotates the rotating portion 30a, and the soapy water 20 blows upward to generate the first bubble 21.
(4) When the first bubble 21 passes through a gap such as a through hole or a slit of the bubble generating portion 14, the second bubble 22 is generated. When the number of bubbles increases, the bubbles reach the second rotating portion 12. At this time, the second bubble 22 does not go upward in the second rotating portion 12. The second foam 22 returns to the soapy water 20 at the bottom of the container 15.
(5) By repeating the above again, microscopic high-density bubbles are formed.

<1st rotating part 11>
The first rotating portion 11 of the first embodiment will be described with reference to the bottom view of FIG. 3A and the partial side view of FIG. 3B.
The first rotating portion 11 has a plurality of splashes 11a around the rotating shaft 16. The splash 11a is inclined with respect to the vertical direction. By rotation, the soapy water 20 at the lower part is blown upward to generate the first bubble 21.

<Second rotating part 12>
The second rotating portion 12 of the first embodiment will be described with reference to the plan view of FIG. 4A and the partial side view of FIG. 4B.
The second rotating portion 12 has a plurality of splashes 12a around the rotating shaft 16. The splash 12a is inclined with respect to the horizontal direction. Due to the rotation, the second bubble 22 that has risen to the upper part is held down.

<Foam generator 14>
5 (a) to 5 (c) are plan views illustrating a part of the bubble generating portion 14.
FIG. 5A shows that the bubble generating portion 14 is reticulated. FIG. 5B shows that the bubble generating portion 14 has a circular opening 14a in the flat plate. FIG. 5C shows that the bubble generating portion 14 has a slit-shaped opening 14a in the flat plate.
The bubble generation unit 14 needs at least an opening through which the first bubble 21 can pass. There are various shapes.
It is preferable that the bubble generating portion 14 substantially surrounds the space between the periphery of the first rotating portion 11 and the rotating shaft 16. It does not have to be completely enclosed.

<Soap water 20>
The soapy water 20 is soapy water, a surfactant, or the like. Any aqueous solution with bubbles can be used.
<Container 15 and rotating part 30a>
The rotating portion 30a changes its position with respect to the container 15 by rotation or the like to generate bubbles. In particular, the rotating portion 30a may move vertically with respect to the container 15 and rotate to generate bubbles.

<First gap 18a and second gap 18b>
There is a second gap 18b between the inner surface of the container 15 and the second rotating portion 12, and there is a first gap 18a between the inner surface of the container 15 and the first rotating portion 11.
The second rotating portion 12 is for suppressing the second bubble 22. The second gap 18b is narrow. Since the first rotating portion 11 generates the first bubble 21, the first gap 18a is large to some extent. At least, the first gap 18a is larger than the second gap 18b.

<Shaft tip 19>
At the tip of the rotating shaft 16, the shaft tip 19 protrudes downward from the first rotating portion 11. The shaft tip 19 comes into contact with the bottom surface of the container 15, and the rotating portion 30a can rotate. However, the shaft tip 19 may be floated from the bottom surface of the container 15 to rotate the rotating portion 30a. Further, there may be a protrusion on the bottom of the container 15 and a recess on the lower part of the rotating portion 30a.
<Effect>
(1) Bubbles can be efficiently generated by rotational movement.
(2) The second rotating portion 12 returns the bubbles to form high-density micro bubbles.

By reversing the rotating portion 30c, the first bubble 21 is generated in the second rotating portion 12. The first bubble 21 rises on the side surface of the bubble generating portion 14. The first bubble 21 enters the bubble generating section 14 from the vicinity of the second rotating section 12, and the second bubble 22 is produced. Again, the second foam 22 passes through the lower foam generating portion 14 and becomes finer. Then, in the second rotating portion 12, the drop of the bubble is suppressed and rises, and the above is repeated to make the bubble finer.
FIG. 7B is a modified example. 7 (b) shows that (1) the container 15 is trapezoidal (conical cone), (2) the lid 32 is provided, and (3) the lid 32 and the rotating portion 30c are shown with respect to FIG. 7 (a). It is different that the seal portion 38 is provided between the and.
