Abstract

PURPOSE:To supply mousse-like soap again immediately after use, by lowering the piston in the cylinder in accordance with pressing down of a pushing bar to transfer the soap solution in the foam chamber to a mixing chamber to mix with air and ejecting it from the delivery outlet as mousse-like foam. CONSTITUTION:When letting a pushing bar 4 go off, the piston 2 rises up in the cylinder 1 due to a spring 3 and hence, a soap solution is sucked from the lower path R4 in the foam chamber S1 of the cylinder 1 and air is mixed in the soap solution through an air hole 14. On the other hand, when the pushing bar 4 is pressed down with a hand, the piston 2 is lowered in the cylinder 1 and hence, a vertical pipe 12 is forced to enter into an inner cylinder 10 and the soap solution in the foam chamber S1 is extruded and raised from a connection hole 11 into a mixing chamber S2 through a plurality of paths R1, R2. And further, the air left in the upper part of the foam chamber S1 is conducted from an air hole 9 into the mixing chamber S2 and mixed with the soap solution in a netted body 8. As a result, the soap solution gets to mousse-like foam and it is ejected from the delivery outlet 5.

[0005]

In the first aspect, when the piston portion is moved upward in the cylinder, the soap solution is supplied into the bubble chamber of the cylinder, and at the same time, air is mixed into the bubble chamber of the cylinder and the bubble chamber is mixed. The soap water mixed with air will generate bubbles, and the soap solution mixed with air will fill the bubble chamber, and then the piston part will be lowered in the cylinder, and the bubbles will be stored in the bubble chamber. The soap solution mixed with the air enters the passage through the communication hole, and further introduces air from the air hole provided in the passage in the piston part, and the air introduced from the air hole makes finer bubbles to form a mousse soap. And is ejected to the outside. Therefore, air is mixed when entering the cylinder and also when exiting from the cylinder, so that good mousse-like soap can be ejected, and bubbles of soap liquid accumulated in the cylinder Even when it disappears with the lapse of time, air is mixed in at the outlet side, so that good mousse-like soap can be discharged.

Further, in the second aspect, the soap mixed with the air stored in the bubble chamber in the cylinder is formed in the inner cylinder by pressing the piston portion from above and lowering it in the cylinder. It is introduced into the mixing chamber through the communication hole and further through the passage, and is further mixed with the air introduced from the air hole in the mixing chamber to form fine mousse-like bubbles, which are discharged to the outside through the passage. Also, when the pressing force on the piston is released, the piston moves upward in the cylinder due to the urging force of the spring, and at this time, soap water is sucked into the cylinder from the soap tank etc. through the passage, but at this time Air is sucked in through the holes and is stored in the foam chamber as a soap solution of foam in which air is mixed well.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are cross-sectional structural views of the mousse-like soap supplying device, and FIG.
Shows the state when the piston is moved downward to discharge the mousse-like soap water. In this mousse-like soap supply device, a piston portion 2 is internally slidable in a cylinder 1, and the piston portion 2 is provided on an upper end of a spring 3 that is raised from a bottom surface portion 1b of the cylinder 1. It abuts and is always urged upward by the urging force of the spring 3.

A push rod portion 4 is integrally formed on the piston portion 2 so as to project upward from the upper surface portion 1a of the cylinder 1. A discharge port 5 is formed in the push rod portion 4, and the push rod portion is formed. An upper passage R3 communicating with the discharge port 5 is formed in the portion 4, and a check valve 6 having a ball 6a is provided in the upper passage R3. The upper passage R3 communicates with a mixing chamber S2 formed in the piston portion 2, and a mesh body 8 is horizontally arranged in the mixing chamber S2, and a lower end of the mixing chamber S2 is provided. A hanging pipe 12 is hung in a downward direction, and a passage R2 communicating with the upper passage R3 is formed in the hanging pipe 12. Also,
An air hole 9 is penetratingly formed in the mixing chamber S2 in parallel with the hanging pipe 12, and the mixing chamber S2 and the bubble chamber S1 in the cylinder 1 are communicated by the air hole 9. There is. An air vent hole 7 is formed in the upper surface 1a of the cylinder 1 to facilitate the sliding movement of the piston 2.

On the bottom surface 1b of the cylinder 1, the inner cylinder 1 is erected upward along the central axis of the cylinder 1.
0 is erected, and the passage R is provided in the inner cylinder 10.
1 is formed. In addition, the base portion 10 of the inner cylinder 10
a is a horizontal communication hole 1 that intersects the passage R1 at a right angle.
1 is formed so as to penetrate, and the communication hole 11 allows passage R
1 and the bubble chamber S1 communicate with each other. Further, a lower passage R4 is formed in the bottom surface 1b of the cylinder 1 so as to communicate with the passage R1 and hang down. A check valve 13 is formed in the bottom surface 1b at the upper end of the lower passage R4. The ball 13a is arranged inside. The lower passage R
Reference numeral 4 is extended further downward from the bottom surface of the cylinder 1 by a tube or the like, and is connected to a soap tank or the like which stores soap liquid (not shown).

In such a structure, when the push rod portion 4 is released from the state shown in FIG. 2, the piston portion 2 moves upward in the cylinder 1 by the urging force of the spring 3, and at this time, the lower passage R4. The soap solution is sucked from the soap tank into the bubble chamber S1 of the cylinder 1 through this, but at this time, the ball 6a of the check valve 6 closes the upper passage R3, and conversely the lower check valve 13 is closed. The ball 13a has a lower passage R
4 is opened, and air is introduced into the lower passage R4 from the air hole 14 formed in the bottom surface portion 1b on the upstream side of the check valve 13 with respect to the soap liquid rising through the lower passage R4. As a result, air is mixed into the soap solution to form a foamy soap solution, and the soap solution passes through the check valve 13 and further through the communication hole 11 and is sucked and stored in the foam chamber S1. When the piston part 2 stops rising, the ball 13
In a, the lower passage R4 is closed to keep the foamy soap liquid sealed in the foam chamber S1.

In this state, as shown in FIG. 2, when the user pushes the push rod portion 4 downward with a finger or the like, the piston portion 2 descends in the cylinder 1 and the hanging pipe 12 is placed in the inner cylinder 10. The downward movement causes the passage R1 and the passage R2 to overlap each other. At this time, the lower check valve 13 is closed, and conversely, the ball 6a of the upper check valve 6 is raised to open the upper passage R3. Then, the soap liquid in the bubble chamber S1 becomes the piston portion 2
Is pushed out by the downward movement, enters the passage R2 through the communication hole 11 and rises into the mixing chamber S2. At this time, the air remaining in the upper portion of the bubble chamber S1 from the air hole 9 is mixed with the mixing chamber S2. The air enters the inside of the mixing chamber S2, and the air is further mixed into the soap to form fine bubbles. Particularly, the air is well mixed in the mesh body 8 to form finer mousse-like bubbles. It is ejected from the discharge port 5 to the outside through the passage R3.

Therefore, in this example, the push rod portion 4 is used during use.
When is pressed and operated, air is mixed in the mixing chamber S2 to surely form a mousse-shaped soap solution, so that the soap solution is stored in the foam chamber S1 for a long time in the state of FIG. 1 and the foam disappears. Even in such a case, the air is always mixed in the mixing chamber S2 at the time of use to form a good mousse-like soap liquid and is discharged to the outside.

Therefore, in this embodiment, when the soap liquid flows into the foam chamber S1, air is mixed from the air holes 14 to be sealed in the foam chamber S1 in a good foam state.
At the time of use, air can be further mixed in the mixing chamber S2, and fine air bubbles can be discharged to the outside by mixing the air twice, so that a good mousse-like soap can be reliably supplied. A large amount of soap liquid can be stored in the bubble chamber S1, and a sufficient amount of mousse-like soap can be discharged during use.

In this embodiment, the hanging pipe 12 is moved up and down in the inner cylinder 10. However, instead of the hanging pipe 12 and the inner cylinder 10, this portion can be expanded or contracted by a tube or bellows-like member. Can be changed to. Further, the mesh body 8 may be changed to a porous body such as ceramic, and the mesh body 8 or the porous body is provided in the upper passage R3 on the downstream side of the check valve 6. Alternatively, they may be provided on the upstream side and the downstream side of the check valve 6, respectively.
