Figure 2a shows an embodiment of a bucket 11 according to the present invention.

Referring to FIG. 2A, the bucket 11 may have a hexahedron shape having a large bottom surface as a whole and may be made of FRP or plastic. A foaming agent such as water or a surfactant may be filled in the bucket 11. Surfactants are intended for the generation of foam and include, for example, anionic surfactants having a carboxylic acid salt, sulfonic acid salt or phosphate structure, cationic surfactants containing quaternary ammonium salts as hydrophilic groups, amphoteric surfactants such as alkylsulfobetaines or alkylcarboxybetaines. Active agents and nonionic surfactants consisting of low molecular weights such as alkylglycols or polymeric systems such as polyethylene glycols and polyvinylalcohols. Foaming agents such as surfactants may be injected into the bucket 11 through the water inlet 24 together with water or into the bucket 11 in various ways. The water level of the water filled inside the bucket 11 may be limited. For example, water may only be filled up to the level limit line 25 and the level limit line 25 formed on the inner side 113 may be set equal to or below the lowest position of the bubble trap 21. The level limit line 25 is for determining the level of water to be filled in the interior of the bucket 11 and may be represented in any form and is not limited to a specific method.

Bubble trap 21 is installed above the water tank 11 or adjacent to the inner top surface 111, and the inside of the bubble trap 21 to induce the flow of bubbles while generating bubbles induction pipe (22a, 22b) It can be connected with. Induction pipes 22a and 22b extend downward from the inside of the water tank 11 and again upward, and are connected to the outside of the water tank 11 through the pipe inlet hole 221. One end of the induction tubes 22a and 22b exposed to the outside of the water tank 11 may be opened or closed and the other end of the induction tubes 22a and 22b may be connected to the bubble trap 21. As shown in the detail section indicated by A of FIG. 2A, an introduction tube 32 connected to the air supply means 12 described in FIG. 1 inside the induction pipes 22a and 22b is used for the induction pipes 22a and 22b. It can be introduced to a certain depth and the bubble generating means 33 can be fixed to the end of the inlet tube 32. The foaming means 33 may be, for example, an air stone, but is not limited thereto. Air stone refers to limewood or poros stone used for the purpose of gradually diffusing oxygen into the tank. Air stones can be made from bonded glass beads or glass fibers and can generate various kinds of bubbles depending on shape, size or coarseness. For example, the air stone can be a blue-colored porous porous stone of ceramic material connected to a plastic nozzle with an air hose of the appropriate diameter, but can be made in various shapes and sizes or colors. The air stone can be mechanically compressed to form a solid aggregate with fine gaps and can be made in various forms depending on the purpose. The bubble generating means 33 according to the present invention includes any means capable of generating bubbles from water and a surfactant, without being limited to air stones.

As shown in A of FIG. 2A, the bubble generating means 33 may be installed at the end of the inflow tube 32 into which oxygen or air is introduced, and the inflow hole 222 formed in the induction pipes 22a and 22b may be formed. Bubbles may be generated from water including the bubble generator introduced into the induction pipes 22a and 22b. The induction pipes 22a and 22b are advantageously connected to the bubble trap 21 via a position adjacent the inner bottom 112. The connection paths of the induction pipes 22a and 22b not only allow water in the water tank 11 to easily flow into the induction pipes 22a and 22b through the inlet hole 222, but also simultaneously generate bubbles easily. It can be collected in the bubble collecting container (21). The generated bubbles may be collected in the bubble collecting container 21 and the bubbles filled in the bubble collecting container 21 may be discharged to the toilet through the bubble discharge pipe 23. One end of the foam discharge pipe 23 is connected to the bubble collecting container 21 through the discharge port 231 and the other end is connected to the water tank by the pipe connecting means T known in the art, such as a T-shaped connecting tube. Can be derived outside of (11).

As shown in FIG. 2A, the outlet 231 may be formed on the opposite side of the portion to which the induction pipes 22a and 22b are connected, and is also formed in the upper portion of the bubble trap 21 with the water container 11 installed. Can be. Such a position of the outlet 231 allows the foam to be continuously discharged into the toilet after the foam collecting container 21 is filled with a sufficient amount of foam. In addition, the pipe connecting means (T) for guiding the bubbles of the bubble collecting container 21 to the outside may be installed near the center in the vertical direction of the water container 11 in the installed state of the water container 11, but is not particularly limited. . However, the pipe connecting means (T) is advantageously provided between the lower portion of the foam trap (21) and the upper portion of the toilet bowl.

The inlet 24 installed above the bucket 11 is for the inflow of water or surfactant and can be installed by any suitable method known in the art and a cover can be installed as necessary.

The amount of bubbles generated in the bubble generating means 33 can be controlled by the air supply means.

Figure 2b shows another embodiment of a bucket for generating bubbles.

Referring to FIG. 2B, the bubble generating means 33 in which the water level limiting line 25 can be set and the end of the inflow tube 32 can be set in the water tank 11, which can be filled with water and the bubble generating agent. The silver may be installed below the foam collecting pipe 27 through the induction pipe 22. The foam collecting tube 27 has a function similar to that of the foam collecting container 21 in the embodiment related to FIG. 2A, and may be installed to cross the bucket 11 from the top to the bottom thereof. Although not shown in FIG. 2B, the upper portion of the foam collection tube 27 may be exposed to the outside of the bucket 11 and closed by an openable cap (not shown). If necessary, the cap may be opened to allow water and foaming agent to be introduced into the bucket. When such a cap is installed, the inlet 24 as described in FIG. 2A does not need to be separately installed. On the other hand, the bottom of the bubble collecting tube 27 may be spaced apart from the inner bottom 112 of the bucket 11 by a predetermined distance t. The spacing of the predetermined interval (t) is to allow the water and the foaming agent inside the bucket 11 to be introduced into the foam collection pipe (27). As an alternative to spaced apart t, an inlet hole (not shown) that can be opened and closed may be installed below the foam collection tube 27. As such, the method of introducing the water and the bubble generating agent into the bubble collecting tube 27 may be formed in various forms, and the embodiment shown in FIG. 2B is exemplary. In addition, it is possible to limit the amount of water and the foaming agent that can be introduced into the foam collecting tube 27 so that the water and the foaming agent are filled only up to a portion just above the foaming means 33, for example.

In the embodiment shown in FIG. 2B, the amount of water and bubble generating agent filled in the bubble generating tube 27 coincides with the level of water and bubble generating agent present in the bucket 11. For example, when the water and the bubble generator is initially filled up to the water level limit line 25 inside the bucket 11, the water and the bubble generator are filled up to the full water level surface 271 inside the bubble generating tube 27. In the bubble generating tube 27, bubbles are filled in the upper portion of the full water surface 271, and the water level inside the bucket 11 is lowered little by little. However, the volume of the entire bucket 11 is large enough to be larger than the volume of the foaming tube 27, and as a result, the water level of the bucket 11 is lowered. The top of is filled with bubbles as the water level drops. When the foam is sufficiently filled, the foam can be discharged to the toilet through the foam discharge pipe (23). The foam discharge tube 23 can be of any shape known in the art, such as, for example, a plastic tube, and the outlet 231 of the foam discharge tube 23 is the top or full surface of the foam generating tube 27 ( It is installed above 271 and the external connection outlet 232 can be installed below or at least below the middle height of the bucket 11, but is not limited thereto. The external connection outlet 231 is similar to the position where the pipe connection means T is installed in the embodiment associated with FIG. 2A. Although not illustrated in the embodiment illustrated in FIG. 2B, the components necessary for generating bubbles may be applied to the embodiment illustrated in FIG. 2B in the same or similar form as those described in the embodiment of FIG. 2A.

Along the circumferential face of the bucket 11 an attachment face 29 may be formed to which a cover for sealing may be attached and the cover may be made of any material known in the art, for example glass or plastic. have.

In the embodiment shown in FIG. 2B, unlike the embodiment of FIG. 2A, only one induction pipe 22 is installed. In addition, only one of the induction tube 22 and the inflow tube 32 and the bubble generating means 33 installed therein are similarly provided. The bubble generating means 33 can be installed in various numbers in consideration of the amount of bubbles generated, and the present invention is not limited by the number of installation of such bubble generating means 33.
