Detailed Description

The following description will be made using embodiments, but the invention is not limited to the following.

(embodiment 1)

< Structure >

The foam generating device 17a according to embodiment 1 is described with reference to a cross-sectional view of fig. 2 (a) and a plan view of fig. 2 (b). The foam generating device 17a has a container 15, a rotating portion 30a, and a rotating mechanism 13.

< rotating portion 30a >

The rotating portion 30a has a first rotating portion 11, a foam generating portion 14, a second rotating portion 12, and a rotating shaft 16, and the rotating shaft 16 connects the first rotating portion 11, the foam generating portion 14, the second rotating portion 12, and the rotating mechanism 13.

The first rotating part 11 rotates to blow up the soapy water 20, thereby producing the first foam 21.

The foam generating portion 14 is a thin plate having through holes. The second foam 22 is generated by passing the first foam 21 through the through holes. Instead of the through hole, a slit may be used. So long as there is a gap.

The second rotating part 12 prevents the second foam 22 from moving upward. The second foam 22 is pressed downward. The second foam 22 advancing downward is formed into the first foam 21 by the first rotating portion 11 again. The above-described operations are repeated to produce a stable foam.

The rotation shaft 16 connects the first rotation portion 11, the foam generating portion 14, the second rotation portion 12, and the rotation mechanism 13. The whole becomes a rotating portion 30a. The rotation shaft 16 is a central shaft when the rotation portion 30a rotates. In this example, the first rotating portion 11 is covered by the foam generating portion 14.

< Container 15>

Soapy water 20 is placed into the container 15. The container 15 has a cylindrical shape. The rotating portion 30a rotates inside the container 15 to generate foam.

< rotation mechanism 13>

The rotation mechanism 13 is an activation portion that rotates the rotation shaft 16 of the rotation portion 30a. Or may be manually rotated. Or may be rotated by a motor or the like.

< Process >

(1) Soapy water 20 is placed into the container 15.

(2) The rotating portion 30a is put into the container 15.

(3) The rotating part 30a is rotated by the rotating mechanism 13, and the soapy water 20 is blown upward to generate the first foam 21.

(4) When the first foam 21 passes through the through-holes, slits, and the like of the foam generating section 14, the second foam 22 is generated. If the foam increases, the foam reaches the second rotating part 12. At this time, the second foam 22 is not moved upward by the second rotating portion 12. The second foam 22 returns to the soapy water 20 in the lower portion of the container 15.

(5) By repeating the above operation again, a high-density foam having a minute shape is formed.

< first rotating portion 11>

The first rotating portion 11 according to embodiment 1 will be described with reference to a bottom view of fig. 3 (a) and a partial side view of fig. 3 (b).

The first rotating portion 11 has a plurality of blades 11a around the rotating shaft 16. The blade 11a is inclined with respect to the vertical direction. The soapy water 20 located at the lower portion is blown upward by the rotation to generate the first foam 21.

< second rotating portion 12>

The second rotating portion 12 according to embodiment 1 will be described with reference to a plan view of fig. 4 (a) and a partial side view of fig. 4 (b).

The second rotating portion 12 has a plurality of blades 12a around the rotating shaft 16. The blade 12a is inclined with respect to the horizontal direction. The second foam 22 rising upward is pressed downward by the rotation.

< foam Generation portion 14>

Fig. 5 (a) to 5 (c) are plan views illustrating a part of the foam generating section 14.

In fig. 5 (a), the foam generating section 14 is shown as a net shape. Fig. 5 (b) shows that the foam generating section 14 has a circular opening 14a in a flat plate. Fig. 5 (c) shows that the foam generating section 14 has a slit-shaped opening 14a in a flat plate.

The foam generating section 14 requires at least an opening through which the first foam 21 can pass. The shape of the foam generating section 14 has various shapes.

In addition, the foam generating portion 14 preferably substantially surrounds a space between the periphery of the first rotating portion 11 and the rotating shaft 16. It need not be completely enclosed.

< soapy Water 20>

The soapy water 20 is soapy water, surfactant, or the like. Any aqueous solution that foams can be used.

< container 15 and rotating portion 30a >

The rotating portion 30a changes position with respect to the container 15 by rotation or the like, thereby generating foam. In particular, the rotating portion 30a may be moved in the up-down direction with respect to the container 15 and rotated to generate foam.

< first gap 18a and second gap 18b >

A second gap 18b is provided between the inner surface of the container 15 and the second rotating portion 12, and a first gap 18a is provided between the inner surface of the container 15 and the first rotating portion 11.

The second rotating part 12 presses the second foam 22. Therefore, the second gap 18b is narrow. The first rotating part 11 generates the first foam 21, and thus 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>

The shaft tip 19 at the tip of the rotation shaft 16 protrudes further downward than the first rotation portion 11. The shaft tip 19 is in contact with the bottom surface of the container 15, and the rotating portion 30a is rotatable. However, the shaft tip 19 may be lifted from the bottom surface of the container 15 and the rotating portion 30a may be rotated. Further, a protrusion may be provided at the bottom of the container 15, and a recess may be provided at the lower portion of the rotating portion 30a.

< Effect >

(1) Foam can be effectively produced by using the spin transfer.

(2) The foam is returned by the second rotating part 12 to form a high-density minute foam.

A high density foam can be produced efficiently and easily compared to existing bubblers. Therefore, the present invention can be applied to beauty parlors, beauty salons, and the like, in addition to the general household.

(embodiment 2) (use of a motor, a manual rotation mechanism, etc.)

The foam generating apparatus 17b according to embodiment 2 will be described with reference to fig. 6.

The points different from embodiment 1 are (1) a rotation mechanism 13 and (2) a foam generating section 14.

The matters not described are the same as those in embodiment 1.

< rotation mechanism 13>

The rotation mechanism 13 has gears on the second rotation portion 12 and the cover 40a, respectively, and rotates the gears of the cover 40, whereby the second rotation portion 12 rotates. As a result, the rotating portion 30b rotates as a whole.

In fig. 6, the gear of the cover 40a is rotated manually, but a rotating device such as a motor may be used.

< foam Generation portion 14>

The foam generating section 14 has a first protrusion 41 and a second protrusion 42 on the side surfaces in addition to the foam generating section 14 of embodiment 1.

The first and

second protrusions

41 and 42 further produce the third foam 23 from the second foam 22. Foam is produced more efficiently.

< Effect >

The foam can be made finer.

Embodiment 3

The foam generating device 17c according to embodiment 3 will be described with reference to fig. 7 (a).

The point of difference from embodiment 1 is that the rotating portion 30c is turned upside down. The matters not described are the same as those in embodiment 1.

The first rotating part 11 is located above and the second rotating part 12 is located below. The foam generating part 14 covers the first rotating part 11. By reversing the rotating portion 30c, the first foam 21 is generated by the second rotating portion 12. The first foam 21 rises on the side of the foam generating section 14. The first foam 21 enters the foam generating section 14 from the vicinity of the second rotating section 12, and the second foam 22 is produced. The second foam 22 passes through the lower foam generating section 14 again to become fine. In the second rotating portion 12, the foam is restrained from descending and ascending, and the above operation is repeated, whereby the foam is made finer.

Fig. 7 (b) is a modification. Fig. 7 (b) differs from fig. 7 (a) in that (1) the container 15 is made trapezoidal (truncated cone), (2) the cover 32 is provided, and (3) the sealing portion 38 is provided between the cover 32 and the rotating portion 30 c.

According to (1), the generation of foam becomes earlier. Since the upper part is not tight, the foam can be effectively generated.

According to (2), the foam can be directed downward by the cover 32, and a high-density foam can be produced.

According to (3), the foam can be sealed, and a high-density foam can be produced.

The seal portion 38 is constituted by a concave portion and a convex portion, but may have other structures. A sealing structure using a rubber material is also possible.

These three structures may also be used in other embodiments. High density foam can be produced more well.

< Effect >

The foam can be made finer.

In addition, the device may be turned upside down in other embodiments.

Embodiment 4

The rotating portion 30e includes a first rotating portion 11, a second rotating portion 12, and a foam generating portion 14.

The first rotating portion 11 is annular.

The second rotating portion 12 is annular, and has a projection on the upper surface on the rotating shaft 16 side. The generated second foam 22 is guided toward the rotating shaft 16 so that the second foam 22 does not grow along the inner surface of the container 15.

The foam generating portion 14 has a plate shape and a flat portion 14b along the inner surface of the container 15. The foam generating portion 14 is constituted by a flat portion 14b and a plate-like body on the container inner side. The plate-like body is substantially perpendicular to the inner surface of the container. A second foam 22 is generated in the gap between the planar portion 14b and the inner surface of the container 15. Since the second foam 22 is generated in the gaps, a fine foam, a high density foam can be generated. It is preferable that the flat portion 14b has no opening or the like. Large, low density foam is not produced due to the openings. In the rotating portion 30e, two foam generating portions 14 are provided at opposite positions.
