Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for taking out a liquid, and more particularly to a device for taking out a soap solution or a shampoo in a bathroom, a lavatory or a toilet.

[0002]

2. Description of the Related Art Conventionally, a liquid take-out apparatus has a container as shown in FIG. 1 or 5 (Japanese Utility Model Publication No. 42-13648) which is mounted upside down, as often seen in a washroom or a toilet. There is a type in which a valve attached to the lower end of a liquid is pushed up by hand to open it, and the liquid is taken out by the drop of gravity.

[0003]

In the conventional liquid removing apparatus of this type, in the conventional removal of the soap liquid or the like, since the liquid is simply closed with a check valve or the like after the removal, the leakage still continues. In addition, when the valve breaks or is damaged, the valve may easily leak immediately, which is not only uneconomical for the user but also unfavorable in appearance.

[0004] Accordingly, it is an object of the present invention to improve these points and to obtain a liquid take-out device with a perfect seal.

[0005] In the above-mentioned conventional structure, when the soap solution is taken out, sometimes the soap solution does not come out when the valve mechanism is pushed by hand. The cause of this is that the soap liquid tends to solidify from about the fourth day when it comes into contact with air, so that the soap liquid solidifies and clogs from the part that comes into contact with air. Further, there are many conventional structures as shown in FIGS. 1 and 5, but since the discharge chamber is in contact with the outside by a check valve, the discharge chamber tends to easily come into contact with air and to be easily solidified from that part. In particular, the discharge pipe for taking out the liquid that comes into contact with air is clogged. Further, it is difficult to determine where the liquid accumulates and solidifies when the diameters of the discharge tubes are equal, and it is difficult to find the clogged portion.

As a result, it is often necessary to remove the liquid removing mechanism from the container and then clean the inside of the discharge pipe and the pipe to remove the clogging. For this reason, the clogging and inspection of the discharge pipe and the pipe require manual operation, and particularly, the operation and inspection at a hotel outside a home or in a large residential area are difficult. SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned problems, to obtain a liquid take-out device which can block contact with air and prevent clogging due to solidification of liquid.

Further, in the conventional liquid removing apparatus, as shown in the conventional example of FIGS. 1 and 5 (Japanese Utility Model Publication No. Sho 42-136648), since it is located behind the pressing member 7,
The user has to reach deeper and the position is difficult to see from above the user, so sometimes the liquid may drop off the hand, but the present invention , The inside of the discharge member that performs the pump action as a liquid flow passage,
An object of the present invention is to perform easy washing by bringing a liquid discharge tube closer to a hand washer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 2 shows one embodiment of the liquid removing apparatus 1 of the present invention.

FIG. 2 shows an example in which the liquid take-out device 1 is mounted in a mounting device for accommodating the liquid container 8 (the mounting device is mounted on a wall surface). In the example shown in FIG. 2, the liquid container 8 containing the soap solution is fixed to a wall surface of a washroom or the like via an appropriate attachment. The liquid extracting device 1 is provided with a liquid container 8 containing a shampoo or the like detachably on the liquid extracting device 1 with its liquid outlet facing downward. In any of the mounting examples, the liquid removing device 1 of the present invention can be applied.

The liquid container 8 is mounted in the screw portion 30 of the attaching / detaching portion 3 of the unloading device 1 by being vertically screwed with the screw inside the liquid container 8.

A spherical check valve 300 is housed in the valve seat 301 in the detachable portion 3. The check valve 300 is connected to the suction port 3
02 is closed or opened. The attachment / detachment unit 3 includes the liquid removal device 1
Attached to the main body 2. The main body 2 has a cylindrical shape, and has a discharge member 4 therein, and constitutes a mechanism that slides inside the main body 2 against a spring 201 to perform a pump action.

The structure of the discharge member 4 includes a chamber 43 and a chamber 45. The chamber 43 has a front portion 40, and the front portion 40
A hole 400 is provided therein and housed in the chamber 43. In the chamber 43, as shown in FIGS.
A disk 41 acting as a valve is provided. The disc 41 is not forcibly supported by a spring or the like in the chamber 43 and can freely move in the chamber 43, so that no extra parts are required.

In this embodiment, the check valve is used in combination with the disk 41. However, it is possible to use a normal spherical check valve. The combination with the plate 41 does not require a member such as a spring that causes unnecessary material fatigue, and can reduce the number of parts.
No assembling is required and only the inside of the room 43 is stored. Since the structure is simple, there is no failure. The action is reliable and the seal is better.

An intermediate portion 42 is provided on the right side of the disc 41. The intermediate portion 42 has a hole 420 and a convex portion 421 projecting toward the chamber 43 as shown in FIG. 2 and FIG. It is provided in. Inside the chamber 45, there is an intermediate portion 42 in front,
At the rear is a rear part 44. In the rear part 44, FIG.
As shown in (3), a plurality of holes 440 through which the liquid flows out are provided.

The hole 440 of the rear portion 44 through which the liquid flows out is provided with a plurality of small holes in FIG. 3 (3), but a large hole can be provided as shown in FIG. 3 (4).
In this case, the diameter of the hole near the center is made relatively large in order to make it difficult for the liquid in the small hole 440 of the rear part 44 to solidify. At the same time, it is provided near the center to prevent the liquid pool in the chamber 45 from decreasing (to reduce the time for releasing the liquid at the next time),
In addition, they are closely attached to the end wall surface 205 of the main body to prevent leakage at the time of closing and to achieve sealing. In addition, the diameter and the number of holes should be considered according to conditions.

The intermediate portion 42 is, as shown in FIG.
The plurality of holes 420 and the plurality of protrusions 42 protruding toward the chamber 43 side.
Although 1 is provided, the number and size thereof can be set arbitrarily.

The right side of FIG. 2 shows the end wall surface 205 of the main body 2.
A discharge tube 5 is provided close to this as shown in FIG. The cross-sectional shape of the discharge tube 5 has a tapered reduction section 500 and an expansion section 50.
And 1. The reason is that the liquid does not accumulate and harden. In this figure, the cross section is formed by a parabolic or arc-shaped curve, but the shape of the discharge tube 5 as shown in FIG. Enlarged part 5 with a straight cross section
01 may be used. On the other hand, the tapered portion may be curved, and the enlarged portion may be linear in cross section, and vice versa.

A pressing member 46 is provided in the main body 2 so that the discharge member 4 can slide manually. Then, the slider 460 of the pressing member 46 is attached to the discharge member 4. In the embodiment, as shown in the drawing, the attachment portion is attached by utilizing the provision of the intermediate portion 42 and the rear portion 44. In this case, since the slider 460 is fixed at two places, there is no shaking and the sliding can be performed reliably.

The operation of the liquid removing device 1 is as follows. First, the pressing member 46 is moved to the left in FIG. 2 by hand against the spring 201. The position shown in FIG. 2 shows the stop position where the spring 201 is compressed. The rest position is the right end in FIG. Then, the check valve 300 of the attachment / detachment part 3 is closed, while the front part 4 is closed.
Although the liquid flows in from the hole 400 of 0, the disc 41 is pushed by the pressure of the flowing liquid, and moves with respect to the intermediate part 42.
Since the hole 420 is not closed due to the presence of the convex portion 421, the liquid flows into the chamber 45 through the hole 420 from the gap at the outer peripheral portion of the disk 41.

The discharge member 4, which has reached the end of the main body 2, moves rightward in FIG. Then, the check valve 3 of the detachable part 300
00 is opened and the flow of liquid starts. In the chamber 43, the liquid flows backward and the disc 41 hits the front surface 40 and closes the hole 400, so that the liquid in the chamber 45 is increased in pressure as the discharge member 4 moves to the right, When the liquid is filled in the chamber 45 by several slides, the liquid flows into the space formed by the discharge member 4 and the main body 2 from the hole 440 this time. Then, the liquid that has flowed into the space is pushed out by the discharge member 4 and discharged from the discharge pipe 5 to the outside.

When the liquid has been taken out, the discharge member 4 is moved to the position shown in FIG.
Is moved by the spring 201 to the right as shown in FIG.
Stop at the end wall surface 205. Therefore, since the hole 440 provided in the rear portion 44 abuts on the end wall surface 205, the liquid is prevented from leaking out of the chamber 45 by being sealed.

Since the air is shut off and does not enter the chamber 45, it is not solidified in the main body 2. Therefore, there is a possibility of solidification in the discharge tube 5 as described above. That is, when the discharge stops, the liquid hardly stays in the enlarged portion 501, but in the case where the liquid stays, the liquid dares to easily accumulate in the lower end portion 510 of the tapered portion 500.

When reusing, the enlarged portion 5 of the discharge tube 5
Since the liquid does not remain at 01 and the liquid is stored at the lower end 510 of the tapered portion 500, when the discharge member 4 starts operating, the liquid flows into the discharge pipe 5 from the hole 440. The inflowing liquid has a tapered shape and is gradually pressurized and pushed in, thereby pushing out the liquid material accumulated at the lower end portion 510. As a result, it was found from an experiment that when the liquid was not used after the liquid was taken out, the problem that the liquid hardened and could not be taken away was solved. As described above, even when the liquid is solidified, it is not necessary to perform any special operation, and it is possible to automatically remove the clogging at the same time as the operation of discharging the normal liquid.

As the sealing structure, since the discharge pipe 5 is provided near the end wall surface 205 of the main body 2, the main body 2 closes the discharge pipe 5, so that the discharge pipe 5 is also doubled so that it becomes double. No leaks. In other words, the sealing is performed twice, and the prevention of leakage is more reliable than in the case where the conventional check valve is provided. Further, since the liquid is retained in the chamber 45 and the disk 41 which functions as a check valve in the chamber 43, the seal is hardly leaked and the seal is doubled by the chambers 43 and 45, so that the seal is more reliable.

Further, since the flow of the liquid flows as a passage in the discharge member 4 acting as a pump, the flow to the outside thereof is
The discharge tube 5 is located near the end of the main body 2, and this position is close to the pressing member 46, so that when pressed, the liquid is placed on the palm immediately, which is preferable. Conventionally, since it is provided inside the discharge member, it is far from the pressing member 46, and the discharge pipe is located below the take-out device and cannot be seen by the user, so there is a surface that does not know where to discharge. However, in the present invention, there is no such fear since the five discharge paths are immediately visible to the side.

In this embodiment, the check valve applied to the reciprocating pump has a shell shape on the upstream side.
Of course, other well-known check valves, such as spherical and plate-shaped, can be applied. or,

In this embodiment, the liquid removing device is installed in the horizontal direction, and the discharge pipe and the liquid container are installed in the vertical direction. However, the liquid extracting device of the present invention is operated by a pump. Regardless of its installation, various other installations can be implemented by those skilled in the art.

Although the liquid-solidification automatic removal structure in the present invention has been described using a soap liquid as an example, other liquids may of course be used.

[0034]

As described above, in the conventional removal of the soap solution and the like, since the soap liquid is simply closed by a check valve or the like after the removal, the leakage may still continue. In the present invention, the liquid can be sealed twice and the chamber is doubled, so that a liquid take-out device having a more reliable leakage prevention structure as compared with the conventional check valve structure is obtained.

According to the present invention, clogging due to a liquid pool, which has been a problem when liquid is taken out of a liquid container containing the liquid, can be performed without a special device or equipment. At the same time, it can be automatically removed.

Further, according to the present invention, the discharge member which performs a pumping operation is improved, and the inside of the discharge member is used as a flow passage, so that the liquid discharge pipe can be made closer to a hand-washing direction, and easy cleaning can be performed. I did it.
