Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an interesting water dispenser suitable for dispensing drinking water, etc., in, for example, ordinary homes and restaurants.

[Prior Art] Conventionally, as this type of water supply device, a hand pump type water supply device with a suction pipe inserted therein has been widely used. However, there is the inconvenience of having to press the pump every time water is supplied, and since it merely has a water supply function, the interior cannot be seen and is not as interesting as this.

[Purpose of the invention] The purpose of the invention is that once the hand pump is operated, it can be used to supply water several times.In addition to having a water supply function, the purpose of the invention is to The purpose is to provide an interesting water dispenser that gives a mysterious feeling of not knowing whether it is coming out or not.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
A water container equipped with a pump mechanism for pressurizing air into the interior has a double-walled structure combining an inner cylinder and an outer cylinder both made of transparent materials, with a narrow gap between the inner cylinder and the outer cylinder, and a narrow gap between the inner cylinder and the outer cylinder. The inside of the inner cylinder is communicated with the inside of the inner cylinder at the lower part of the inner cylinder, and the water stored in the inner cylinder is passed through the gap from below the inner cylinder, and water is supplied by air pressure from a water supply port connected above the gap. This water dispenser is characterized by:

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

FIG. 1 is a sectional view showing an embodiment of the water supply device according to the present invention, and FIG. 2 is an external view thereof. The water container has a double-walled structure consisting of an inner cylinder 1 and an outer cylinder 2, both made of a transparent material, and a narrow gap 3 of about 2 mm is formed between the inner cylinder 1 and the outer cylinder 2. The inside of the inner cylinder 1 and the gap 3 are connected at the lower part of the inner cylinder 1. A partition tube 4 is screwed onto the upper part of the outer tube 2, and a partition wall 5 provided integrally with the partition tube 4 has a threaded tube 6 screwed onto the inside thereof, so that the inner surface of the inner tube 1 is connected to the partition wall 5. It is pressed. Therefore, the inner cylinder 1 is separated from the outer chamber 8 connected above the gap 3 by the partition wall 5, and the outer chamber 8 is provided with a water supply port 9. Further, a funnel-shaped water inlet 10 communicating with the inner cylinder 1 is provided at the center of the partition cylinder 4.

A lid 11 is removably screwed onto the upper side of the partition cylinder 4, and the lid 11 is equipped with a pressure regulating valve 12 and a pump mechanism 13. Pump mechanism 13
The cylinder chamber 14 has an upper opening and is integrally formed with the lid body 11, a hand-push piston 15 that slides inside the cylinder chamber 14, and a compression cylinder housed in the cylinder chamber 14 for pushing the hand-push piston 15 upward. Consisting of a spring 16, a first check valve 17 provided at the bottom of the cylinder chamber 14, and a second check valve 18 provided at the bottom of the hand piston 15, when the hand piston 15 is pushed down, , air in the cylinder chamber 14 can be sent into the inner cylinder 1 through the first check valve 17.

On the other hand, a bottom cover 20 is provided at the lower part of the outer cylinder 2, but in order to communicate between the inner cylinder 1 and the gap 3, a A decorative floor board 21 as illustrated in FIGS. 3a and 3b is laid. Since this decorative bottom plate 21 has a notch 22 in the peripheral portion on which the lower end of the inner cylinder 1 is placed, the inner cylinder 1 and the gap 3 are communicated through this notch 22. If a decorative board in the shape of a flower, a family crest, or any other appropriate shape is used as the decorative board 21, it is effective both in terms of design and as a double-layer blind board. However, if a communication gap, recess, or small hole is provided at the lower end of the inner cylinder 1, this decorative bottom plate 21 is not necessarily necessary.

In addition, between the outer cylinder 2 and the partition cylinder 4, the partition cylinder 4
and the lid body 11, between the partition wall 5 and the threaded cylinder 6, between the cylinder chamber 14 and the hand piston 15, or between the outer cylinder 2 and the bottom lid 20, etc. Needless to say, a gasket 23 is provided as appropriate to prevent air leakage, water leakage, etc. In addition, a hand piston 1 is provided in the cylinder chamber 14.
5 is provided with a stopper to prevent it from falling off, and the water supply port 9 is further connected to a water supply pipe 25 equipped with a well-known suitable socket 24 as illustrated in FIG.

To use the water dispenser of this embodiment, first
1 is removed and water is injected into the water storage chamber 7 from the water inlet 10. In this case, since the inner cylinder 1 and the gap 3 communicate with each other at the lower end of the inner cylinder 1, water also flows into the gap 3 and rises above the gap 3 due to capillary action. Next, when the hand piston 15 is pushed down after tightening the lid 11, the air in the cylinder chamber 14 is released to the first check valve 17 as described above.
The air is press-fitted into the pressure air chamber 19 through the air. Of course,
When the hand piston 15 is released, the hand piston 15 is pushed up by the compression spring 16 and moves to the first position.
The second check valve 17 is closed, and the second check valve 18 is opened, allowing outside air to enter the cylinder chamber 14. Therefore, when the hand piston 15 is continuously pushed down several times, the pressure inside the inner cylinder 1 increases, and this pressure causes the water inside to fill the outer chamber 8 through the gap 3, causing the water in the inner cylinder 1 to fill up in the outer chamber 8, and even in the pot 24. If you open it, water supply pipe 2 will flow from water supply port 9.
Water is supplied to the outside through 5. This water supply is for inner cylinder 1
This can be continued until the internal pressure reaches atmospheric pressure, so once the internal pressure is increased by operating the hand piston 15, there is no need to push the hand piston 15 every time water is supplied.

The water inside flows from the bottom of the inner cylinder 1 to the gap 3 between it and the outer cylinder 2.
Water is supplied to the outer chamber 8 through the inner tube 1, and both the inner tube 1 and the outer tube 2 are made of transparent material, and the gap 3 is
Since the water level is at the top due to capillary action, it is difficult to see a double structure when viewed from the outside. Therefore,
At the time of water supply, the water surface S only falls, and the phenomenon that water is rising from the surrounding gap 3 cannot be easily detected.

In addition, in the above-mentioned embodiment, in order to partition the inner cylinder 1 and the outer chamber 8, the case where the partition cylinder 4 and the threaded cylinder 6 were used was shown, but the partition cylinder 4 and the thread cylinder 6 are not necessarily used. The inner cylinder 1 and the outer chamber 8 can be separated. Further, various modifications can be made to the structure illustrated in FIG. 1.

[Effects of the invention] As explained above, the water dispenser according to the present invention not only has a water supply function, but also a person looking from the outside can only see the phenomenon that the water level inside drops when water is being supplied. You have no idea if water is coming out of the water pipe, and it's interesting that it feels as if you're watching magic. Further, it has the advantage that it is possible to easily check how much water is left inside, and there is no need to operate a hand pump every time water is supplied.
