[Effect of invention]

The bubbler, the bubble generating device, and the bubble generating method of the present invention can generate high-density bubbles.

Hereinafter, although an Example demonstrates it, this invention is not limited to these. (Example 1) ＜Construction＞ The bubble generator 17a of Example 1 is demonstrated with the sectional drawing of FIG. 2(a) and the top view of FIG. 2(b). The bubble generating device 17a includes the container 15, the rotating part 30a, and the rotating mechanism 13.

<Rotating part 30a> The rotating part 30a includes the first rotating part 11, the bubble generating part 14, the second rotating part 12, and the first rotating part 11 and the bubble generating part 14, and the second rotating part 12 and the rotating mechanism 13. Rotary shaft 16 . The 1st rotating part 11 is made into the 1st bubble 21 by blowing up the soapy water 20 by rotation. The bubble generating portion 14 is a thin plate having through holes. The second bubbles 22 are generated by passing the first bubbles 21 through the through holes. Even if it is not a through hole, it may be a slit. Just have a gap. The second rotating part 12 prevents the second air bubbles 22 from advancing upward. The second air bubble 22 is pressed downward. The second air bubble 22 advancing downward becomes the first air bubble 21 in the first rotating part 11 again. By repeating this process, solid bubbles can be generated. The rotating shaft 16 connects the first rotating part 11 and the bubble generating part 14 and the second rotating part 12 and the rotating mechanism 13 . The whole becomes the rotating part 30a. The rotating shaft 16 is a central axis when the rotating part 30a rotates. In this example, the first rotating portion 11 is covered by the bubble generating portion 14 .

<Container 15> In the container 15, soapy water 20 is put. The container 15 is cylindrical. Inside the container 15, the rotating part 30a is rotated to generate air bubbles. <Rotation mechanism 13> The rotation mechanism 13 is an activation part that rotates the rotation shaft 16 of the rotation part 30a. Manual rotation is also possible. Alternatively, it may be rotated by a motor or the like.

<handler> (1) Put the soapy water 20 into the container 15 . (2) Put the rotating part 30 a into the container 15 . (3) The rotating part 30a is rotated by the rotating mechanism 13, and the soapy water 20 is blown upward, and the first air bubbles 21 are generated. (4) When the first air bubbles 21 pass through gaps such as through holes and slits in the air bubble generating portion 14 , the second air bubbles 22 are generated. If the air bubbles increase, the air bubbles will reach the second rotating part 12 . At this time, the second air bubble 22 is prevented from proceeding upward by the second rotating portion 12 . The soapy water 20 in the lower part of the container 15 is returned to the 2nd bubble 22. (5) By repeating the above again, microscopic high-density air bubbles can be formed.

<1st rotating part 11> The 1st rotating part 11 of Example 1 is demonstrated from the bottom view of FIG.3(a), and the partial side view of FIG.3(b). The first rotating part 11 has a plurality of blades 11 a around the rotating shaft 16 . The wings 11a are inclined with respect to the vertical direction. By rotating, the soapy water 20 in the lower part is blown upward, and the 1st air bubble 21 is generated.

<Second rotating part 12> The 2nd rotating part 12 of Example 1 is demonstrated from the top view of FIG. 4 (a), and the partial side view of FIG. 4 (b). The second rotating part 12 has a plurality of blades 12 a around the rotating shaft 16 . The wings 12a are inclined with respect to the horizontal direction. By the rotation, the second air bubble 22 rising upward is pressed downward.

<Bubble generation part 14> FIGS. 5( a ) to 5 ( c ) are plan views illustrating a part of the bubble generating portion 14 . In Fig. 5(a), it is shown that the bubble generating portion 14 is formed in a net shape. Fig. 5(b) shows that the bubble generating portion 14 has a circular opening 14a in a flat plate. As shown in Fig. 5(c), the air bubble generating portion 14 has a slit-shaped opening 14a in a flat plate. The bubble generating portion 14 must be at least an opening through which the first bubbles 21 can pass. Its shape has various shapes. In addition, 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 is not necessary to surround completely.

＜Soapy water 20＞ The soapy water 20 is soapy water, a surfactant, and the like. Foamed aqueous solutions can be utilized. <The container 15 and the rotating part 30a> The rotation part 30a changes the position with respect to the container 15 by rotation etc., and generates air bubbles. In particular, the rotating part 30a may be moved and rotated in the vertical direction with respect to the container 15 to generate air bubbles.

<1st gap 18a and 2nd 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 is for pressing the second air bubbles 22 . The second gap 18b is narrow. In the first rotating part 11, in order to generate the first air bubbles 21, the first gap 18a has a certain size. At least the first gap 18a is larger than the second gap 18b.

<Shaft tip 19> The front end of the rotating shaft 16 , that is, the shaft front end 19 is projected downward from the first rotating part 11 . The front end 19 of the shaft is in contact with the bottom surface of the container 15, but the rotating part 30a can still be rotated. However, the rotating part 30a may be rotated so that the shaft front end 19 is raised from the bottom surface of the container 15 . Moreover, the bottom part of the container 15 may have a protrusion, and the lower part of the rotating part 30a may have a concave part. ＜Effect＞ (1) Air bubbles can be generated more efficiently by rotational movement. (2) By returning the air bubbles by the second rotating part 12, high-density micro-bubbles can be formed. Compared with conventional bubblers, high-density bubbles can be efficiently and easily generated. Therefore, it can be used in beauty salons, beauty salons, and the like in addition to ordinary households.

(Example 2) (Using a Motor, Manual Rotation Mechanism, etc.) Referring to Fig. 6, the bubble generating device 17b of the second embodiment will be described. The difference from the first embodiment is (1) the rotation mechanism 13 and (2) the bubble generating part 14 . Unexplained matters are the same as those in Example 1. <Rotation mechanism 13> The rotating mechanism 13 has gears in the second rotating part 12 and the cover 40 a, respectively, and rotates the second rotating part 12 by rotating the gears of the cover 40 . As a result, the entirety of the rotating portion 30b rotates. In addition, in Fig. 6, although the gear of the cover 40a is rotated manually, a rotating device such as a motor may be used.

<Bubble generation part 14> The bubble generating portion 14 has the first protrusion 41 and the second protrusion 42 on the side surface in addition to the bubble generating portion 14 of the first embodiment. The first projections 41 and the second projections 42 are formed from the second bubbles 22 and the third bubbles 23 are further produced. Generate air bubbles more efficiently. ＜Effect＞ The bubbles can be further thinned.

(Example 3) 7(a), the bubble generating apparatus 17c of Example 3 is demonstrated. The difference from the first embodiment is that the upper and lower sides of the rotating portion 30c are reversed. Unexplained matters are the same as those in Example 1. The first rotating part 11 is up, and the second rotating part 12 is down. The bubble generating part 14 covers the first rotating part 11 . The first air bubbles 21 are generated by the second rotating portion 12 by inverting the rotating portion 30c. The first air bubbles 21 rise along the side surface of the air bubble generating portion 14 . The first air bubbles 21 enter the air bubble generating part 14 from the vicinity of the second rotating part 12 and are produced as the second air bubbles 22 . Again, the second air bubbles 22 pass through the lower air bubble generating portion 14 and become thinner. Then, the second rotating part 12 is raised to suppress the drop of the air bubbles, and the above is repeated to make the air bubbles thinner. Fig. 7(b) is a modified example. Fig. 7(b), for Fig. 7(a), (1) the container 15 is formed into a trapezoidal (conical) shape, (2) a lid 32 is provided, (3) a seal is provided between the lid 32 and the rotating part 30c The point of part 38 is different. By (1), the generation of bubbles is more rapid. Since the upper part is thinned, air bubbles can be efficiently generated. By (2), the air bubbles can be moved downward by the cover 32, and high-density air bubbles can be produced. By (3), the air bubbles can be confined, and high-density air bubbles can be produced. Although the sealing portion 38 is constituted by a concave portion and a convex portion, other structures may be used. An airtight structure using a rubber material may also be used. These three configurations can also be used in other embodiments. Higher density bubbles can be made. ＜Effect＞ The bubbles can be further thinned. In addition, other embodiments may be reversed up and down.

(Example 4) 8, the bubble generator 17d of Example 4 is demonstrated. The difference from Embodiment 1 is the configuration of the rotating portion 30d. Unexplained matters are the same as those in Example 1. The first rotating part 11 and the second rotating part 12 are connected by the bubble generating part 14 . A space is formed by the first rotating part 11 , the second rotating part 12 , and the bubble generating part 14 . The first air bubbles 21 are surely moved toward the second air bubbles 22 . ＜Effect＞ The bubbles can be further thinned.

(Example 5) The bubble generating apparatus 17e of Example 5 is demonstrated with reference to Fig. 9 (a) - Fig. 9 (b). The difference from Embodiment 1 is the configuration of the rotating portion 30e. Unexplained matters are the same as those in Example 1. Fig. 9(a) is a perspective view of the rotating part 30e of the bubble generating device 17e according to the fifth embodiment. Fig. 9(b) is a cross-sectional view of the bubble generating device 17e of the fifth embodiment. Similar to the above-described embodiment, the rotating portion 30 e is placed in the container 15 and rotated by the rotating mechanism 13 .

The rotating part 30 e includes the first rotating part 11 , the second rotating part 12 , and the bubble generating part 14 . The first rotating part 11 is annular. The second rotating portion 12 is annular and has a protrusion on the upper surface thereof on the side of the rotating shaft 16 . The generated second air bubbles 22 are induced to the rotating shaft 16 side so as not to grow along the inner surface of the container 15 . The bubble generating portion 14 is plate-shaped and has a flat portion 14b along the inner surface of the container 15 . The bubble generating portion 14 is constituted by a flat surface portion 14b and a plate-like body on the inner side of the container. The plate-like body is substantially vertical on the inner surface of the container. As a result, the second air bubbles 22 are generated in the gap between the flat surface portion 14b and the inner surface of the container 15 . Since it is generated by the gap, fine air bubbles and high-density air bubbles can be generated. In the flat portion 14b, it is preferable that there is no opening or the like. So that low-density air bubbles larger than the opening are not generated. In the rotating part 30e, two bubble generating parts 14 are provided in the positions facing each other.

Figs. 9(c) to 10(d) are modifications of the rotating part 30e of Fig. 9(a). In FIG. 9(c), the rotating part 30e has four bubble generating parts 14. As shown in FIG. In Fig. 10(a), the rotating part 30e has six bubble generating parts 14. As shown in FIG. In FIG. 10(b), in the rotating part 30e, the flat body inside the bubble generating part 14 has an opening. Although the second rotating portion 12 is flat, it may be annular. In FIG. 10(c), in the rotating part 30e, the bubble generating part 14 is a flat plate shape and has an opening. The second rotating portion 12 is annular. In Fig. 10(d), the first rotating part 11 has wings 12a (plate-shaped bodies). The wing 12a is a plate-like surface parallel to the upper or lower surface of the container. Close a part. It is the same as the 3rd (a), 3rd (b) of Example 1. The second rotating part 12 may have wings 12a. ＜Effect＞ The bubbles can be further thinned.

(Example 6) 11 (a) - 11 (d), the rotating part 30g of Example 6 will be described. Fig. 11(a) and Fig. 11(d) are perspective views of the rotating part 30g according to the sixth embodiment. Fig. 11(b) and Fig. 11(c) are enlarged perspective views of the rotating part 30g of the sixth embodiment. Fig. 11(e) and Fig. 11(f) are front views of the rotating part 30g. 11(g) and 11(h) are plan views illustrating the process of forming fine bubbles 74 and 75 in the bubble generating portion 14, and the rotation portion is partially omitted. The difference from the fifth embodiment is the structure of the rotating portion 30g. Matters not described are the same as those in Examples 1 to 5. The first rotating part 11 and the second rotating part 12 are linear plates. The bubble generating portion 14 includes an outer plate 14e, an inner plate 14c, and an opening 14a. Each is parallel in the up and down direction. The air bubbles on the inner surface of the container 15 are scraped up by the outer plate 14e, and the air bubbles are thinned by the inner plate 14c and returned to the inner surface of the container from the opening 14a. The rotation direction of the rotating part 30g may be clockwise when viewed from above. Furthermore, as shown in Fig. 11(g) and Fig. 11(h), the air bubbles 75 can be made thinner by continuously entering and exiting the air bubbles 74 between the inner plate 14c and the outer plate 14e many times. A modified example is shown in Fig. 11(f). Fig. 11(f) is a modification of the rotating part 30g. The first rotating part 11 and the second rotating part 12 may be provided with net parts 11a and 12b. The generation efficiency of air bubbles can be further improved by either of the net parts 11b and 12b. ＜Effect＞ The bubbles can be further thinned. In addition, the inner panel 14c may not be inclined. It may be perpendicular to the rotation direction, or may be perpendicular to the outer plate 14e. In addition, the cross section of the end (outer side) of the outer plate 14e may be an arrow shape, a wedge shape, or a wing.

(Example 7) 12 (a) - 13 (b), the bubble generator 17f of Example 7 is demonstrated. The difference from Embodiment 1 is the configuration of the rotating portion 30f. Unexplained matters are the same as those in Example 1. Fig. 12(a) is a perspective view of the rotating part 30f of the bubble generating device 17f of the sixth embodiment. Fig. 12(b) is a cross-sectional view of the bubble generating device 17f of the sixth embodiment. The rotating part 30f is different from the above-mentioned embodiment and has a pressing part 40b. The extrusion part 40b pushes the surrounding air bubbles downward. The container 15 has a cylinder 40c which is different from the above-mentioned embodiment. The cylinder 40c is a cylindrical body that moves the air bubbles downward. FIGS. 12( c ) and 12 ( d ) are perspective views showing the operation of the container 15 . The cylinder 40c is changed between the state shown in Fig. 12(c) and the state shown in Fig. 12(d). The cylindrical tube 40c has a door 43 and an opening 40d along the side surface thereof. In FIG. 12(c), the opening 40d is closed by the door 43. As shown in FIG. In Fig. 12(d), the door 43 is moved so that the opening 40d is opened. In this example, the rotating part 30f is preferably counterclockwise when viewed from above, so that air bubbles can be easily ejected.

The processing procedure will be described with reference to the cross-sectional views of the bubble generating device 17f in Figs. 13(a) and 13(b). FIG. 13( a ) shows a state in which the first air bubble 21 and the second air bubble 22 are generated by rotating the rotating part 30 f by the rotating mechanism 13 . Fig. 13(b) shows a state in which the door 43 of the cylinder 40c is moved and the opening 40d is opened after Fig. 13(a). When the rotating part 30f is rotated in this state, air bubbles are introduced into the cylinder 40c through the door 43, and the air bubbles are moved downward by the extrusion part 40b. At the same time, the discharge port 44 is opened to discharge air bubbles toward the container 45 .

<Variation> Fig. 14(a) is a cross-sectional view of a modification of the bubble generating device 17f. Fig. 14(b) is a diagram showing the control of the bubble generating device 17f. In Fig. 14(a), the bubble generating device 17f further includes a supply unit 52. As shown in Figs. The supply unit 52 holds the soapy water 20 and supplies the soapy water 20 to the container 15 by opening the valve 51 . The valve 51 is opened and closed by the control unit 53 . The control unit 53 also controls the rotation mechanism 13 . That is, the control unit 53 controls the rotation mechanism 13 and the supply unit 52 . <handler> (1) The soapy water 20 is replenished from the supply unit 52 to the container 15 . (2) The rotating part 30f is rotated by the rotating mechanism 13 . (3) After the bubbles are sufficiently formed, the rotating part 30f is stopped, the door 43 of the cylinder 40c is moved, and the opening 40d is opened. (4) After that, the rotating part 30f is rotated, the air bubbles are introduced into the cylinder 40c through the door 43, and the air bubbles are moved downward by the extrusion part 40b. At the same time, the discharge port 44 is opened to discharge air bubbles toward the container 45 . Air bubbles are easily expelled from the container 15f. ＜Effect＞ The bubbles can be further thinned.

(Example 8) 15 (a) - 15 (b), the bubble generator 17g of Example 8 is demonstrated. The difference from the above-described embodiment is the air blowing portion 60 . In any of the above-described embodiments, the air blowing portion 60 may be provided. The unexplained matters are the same as those of the above-mentioned embodiment. Fig. 15(a) is a cross-sectional view of the bubble generating device 17g of the eighth embodiment. Fig. 15(b) is a perspective view of the air blowing part 60 of the eighth embodiment. The air bubble generating device 17g is provided with an air blowing part 60 at the rotating shaft 16 of the air bubble generating device 17c in Fig. 7 and the third embodiment. The air blowing part 60 has the blowing part 60b in the introduction cylinder 60a and the front-end|tip. The introduction tube 60a sucks in the outside air and sends it out toward the blowing part 60b. The blowing part 60b supplies the air to the soapy water 20 .

It is easy to foam by being supplied with air. It is preferable that the blowing part 60b is located in the lower part of the container 15. The air blowing part 60 may be provided independently in the rotating part 30c. In addition, the air blowing part 60 may be provided in any one of the rotating parts of the above-mentioned embodiments. The air blowing part 60 is tubular, has a blowing part 60b at the front end, and blows air into the soapy water 20 from the outside. The blowing part 60b is formed by cutting a pipe obliquely, and has an opening on the opposite side of the rotation direction of the air blowing part 60 . Thereby, air is naturally blown in from the introduction tube 60a. In addition, a pump may be connected to the introduction cylinder 60a, and air may be forcedly blown into the introduction cylinder 60a. ＜Effect＞ The bubbles can be further thinned.

(Example 9) 16(a) to 16(b), the bubble generating apparatus 17h of Example 9 will be described. Fig. 16(a) is a cross-sectional view of the bubble generating device 17h. Fig. 16(b) is a perspective view of the air blowing part 60 of the air bubble generating device 17h of the ninth embodiment (the first rotating part 11 is omitted). The difference from the above-described eighth embodiment is that the air blowing part 60 is different. The unexplained matters are the same as those of the above-mentioned embodiment. The side surface of the air blowing part 60 has the helical protrusion 14d. The upper part has the first rotating part 11 . The lower part has the blowing part 60b as the second rotating part 12 . Along with the rotation of the rotating part 30c, air is naturally blown in from the blowing part 60b to generate air bubbles. By moving the air bubbles so as to move above the protrusions 14d, the air bubbles are efficiently thinned. The air bubbles are suppressed from the lower part by the first rotating part 11, and the air bubbles move from the lower part to the upper part again and become thinner. ＜Effect＞ The bubbles can be further thinned.

(Example 10) 17, the application of the bubble generating apparatus of Example 10 is demonstrated. Fig. 17 is an application example using the bubble generating device 17h. Using the bubble generating apparatus of Example 9, bubbles were generated in the large container 70 . The container 70 is, for example, a large one such as a bathtub and has water 73 . The vessel 70 may also be a pool or aqueduct (waterway). The bubble generating device 17h has the guide part 71 on the side surface and the suction part 72 on the lower part. The suction part 72 is a fin or the like that attracts water. The guide part 71 is a wall which raises a bubble along the side surface of the bubble generator 17h. At this point, the bubbles are thinned. In addition, the bubble generator 17h may be the bubble generator of another Example. The air bubbles produced by the air bubble generator 17h are ejected toward the water 73 from above, and the air bubbles are produced from the entire container 70 .

(Example 11) In Example 6, by replacing the soapy water 20 with egg whites, a high-density meringue can be efficiently and easily completed compared with a conventional bubbler. Therefore, the bubble generating device and the bubble generating method of the present invention can also be used in general households, food manufacturing, restaurants, bakeries, and the like.

(Example 12) In Example 6, the soapy water 20 was replaced with whipped cream, and high-density whipped cream could be efficiently and easily completed compared with a conventional foamer. Therefore, the bubble generating device and the bubble generating method of the present invention can also be used in general households, food manufacturing, restaurants, bakeries, and the like.

(Department) The above-described embodiments can be combined with each other. In the above-mentioned embodiment, it is preferable to have a lid on the container 15 . The air bubbles can be suppressed from being ejected to the outside, and the air bubbles can be returned to the inside of the container 15 again, and the air bubbles can be made thinner. In the above-mentioned embodiment, although the second rotating part 12 is not necessary, it is preferable if it exists. Fig. 18(a) and Fig. 18(b) are cross-sectional views of an example in which the second rotating portion 12 is not shown. In Fig. 18(a), although there is no second rotating part 12, it has a container upper part 15a. By the container upper part 15a, the air bubbles which rise up are restrained in the downward direction, and the air bubbles are thinned. In FIG. 18(b), the generated air bubbles are immediately ejected toward the water 73, and the air bubbles are ejected toward the entire water 73. As shown in FIG. In addition, although the rotation mechanism 13 of the above-mentioned embodiment was arrange|positioned at the upper part, it may be arrange|positioned at the lower part using a belt etc., as well. If it is arranged in the lower part, the heavier one can be located below, and the device can be more stable. [Industrial Availability]
