Description

The present invention relates to a movable open tabletop fountain device that fountains the air by increasing the pressure of air according to a natural principle without using a motor, a pump or the like by a power source.

A fountain device that fountains using a motor or a pump is generally used as a tabletop or a toy (see, for example, Patent Document 1). Apart from this, a tabletop fountain device that fountains by the circulation of air and water based on the natural principle without using electricity, a pump or the like has also been developed (see, for example, Patent Documents 2, 3, and 4). A feature of the fountain device based on the circulation of air and water is that the fountain device is placed in a sealed state. By this sealed state, the water for fountain stored in the water reservoir disappears and the fountain is terminated. Returning the discharged water discharged to the water tank to its original state, that is, returning the water to the water storage tank is possible, enabling repeated fountains.

However, in this sealed fountain apparatus, there is a problem that the feeling of release is small because the fountain is also fountained into the sealed space. On the other hand, in the present invention, it is the same that the fountain is circulated by the circulation of water and air, but it is thought that it is difficult to fountain not in the sealed space but in the open air to increase the feeling of release and in a sealed state. It enables water return work and realizes repeated fountains.

That is, an object of the present invention is to realize a fountain apparatus that can be easily moved without using a motor or a pump as in the prior art and that can repeatedly fountain into the air using stored water.

FIG. 1 shows a typical sealed fountain device that uses a fountain device in a sealed state without using a pump to fountain water by circulation of water and air according to a natural principle. The present invention is based on the sealed fountain device of FIG. 1 and realizes an open fountain device that fountains in the air instead of the sealed space of FIG.

Fig.1 (a) is explanatory drawing of the conventional sealed fountain apparatus. It has a fountain chamber 2, a water storage chamber 3, and a water collection chamber 4 that are sealed from the top to the bottom. The upper end opens in the fountain chamber 2, and the inflow hole 1 a at the lower end does not contact the lower portion of the water storage chamber 3. A fountain pipe 1 that is positioned a little apart, i.e., "leaving a gap", a water pipe 5a that has an upper end that opens in the fountain chamber 2 and a lower end that leaves a gap in the lower part of the water collection chamber 4; A fountain cylinder A having a lower end opened in the water collecting chamber 4 and an upper end disposed with a ventilation pipe 5b located above the water storage chamber 3 leaving a gap is used.

When the stored water Wa is stored almost completely in the water storage chamber 3 and then the staying water Wb stays below the top of the fountain pipe 1 in the fountain chamber 2, the fountain starts by the following circulation of water and air. FIG. 1A shows the initial water level at which the fountain begins with a solid line.

The accumulated water Wb flows out to the water flow pipe 5a and is discharged to the water collecting chamber 4. Since the air pressure in the fountain chamber 2 is reduced by the outflow of the staying water Wb, an action of sucking the stored water Wa into the fountain pipe 1 occurs. On the other hand, the same amount of air is pushed out to the water storage chamber 3 through the ventilation pipe 5b by the discharged water Wc discharged to the water collecting chamber 4, and the pressure of the water in the water storage chamber 3 is increased. To push up. Thus, the stored water Wa ascends the fountain pipe 1 by the action of sucking up and pushing up the stored water Wa and the fountain starts. The same amount of water that has flowed out of the fountain chamber 2 is fountained and falls into the fountain chamber 2. Accordingly, the amount of the retained water Wb in the fountain chamber 2 remains unchanged in the initial state without changing.

When the stored water Wa in the water storage chamber 3 disappears due to the fountain, one fountain is completed. At the end of the fountain, the length of the fountain pipe 1 is equal to or less than the water level difference ΔH (= water level of Wb−water level of Wc) between the accumulated water Wb and the discharged water Wc. Is done. The water collection chamber 4 stores discharged water Wc that is a combination of the stored water Wa and the accumulated water Wb (see FIG. 1B).

After the fountain is over and all the accumulated water Wb is discharged into the water collection chamber 4, the fountain tube A is turned upside down, that is, "inverted" to prepare for the re-fountain. FIG. 1C shows a state immediately after the fountain tube A is inverted. From the state of FIG. 1C, the discharged water Wc collected in the water collection chamber 4 flows down the ventilation pipe 5b and enters the water storage chamber 3. The amount of water discharged and flowing over the inflow hole 1a of the fountain pipe 1 flows down the fountain pipe 1 and is discharged into the fountain chamber 2 to become retained water Wb, and the amount of water below the inflow hole 1a of the fountain pipe 1 becomes stored water Wa (FIG. 1 (d)). When the fountain tube A is turned over again from the state of FIG. 1 (d), it returns to the original state of FIG. 1 (a) and re-fountain starts.

FIG. 2 is an explanatory view of the open fountain device of the present invention. From the upper side to the lower side, it has a fountain 12 whose upper part is open, a water storage chamber 13 sealed below it, and a water collecting chamber 14 sealed below it. The lower end inflow hole 11a is located in the lower part of the water storage chamber 13 leaving a gap, and the upper end is opened in the fountain chamber 12, and the lower end has a gap in the lower part of the water collecting chamber 14. A fountain cylinder B is used in which a water pipe 15a that is left and a ventilation pipe 15b that has a lower end that opens in the water collection chamber 14 and an upper end that is positioned leaving a gap above the water storage chamber 13 are used. The

In the fountain tube B, a water-sparing chamber 16 that was not in the fountain tube A is attached inside or outside the water reservoir 12. FIG. 2 shows the case where it is mounted inside. The stagnation chamber 16 has an upper surface and a lower surface and is attached to the fountain 12 at the same height, and a lower portion has an outflow hole 16 a communicating with the fountain 12. An upper end opens in the upper part of the water chamber 16, an inflow hole 17 a at the lower end is located above the inflow hole 11 a of the fountain pipe 11, and the water pipe 17 that penetrates the lower surface of the water chamber 16 in a sealing manner is connected. Has been.

If the reservoir water Wa is stored almost in the reservoir chamber 13 and then stays in the fountain chamber 12 below the top of the fountain pipe 11 (see the solid line in FIG. 2A), the retained water Wb. Flows into the water flow pipe 15a and is discharged to the water collection chamber 14, and the same amount of air as the discharged water Wc is pushed out to the water storage chamber 13 through the air flow pipe 15b, and the air in the water storage chamber 13 is increased in pressure. The stored water Wa is pushed up to the fountain pipe 11 and the fountain starts.

Although the action of pushing up the stored water Wa also occurs in the stagnant pipe 17, the stored water Wa does not flow out from the upper part of the stagnant pipe 17 if the stagnant pipe 17 is long, but if it is short, it flows out. The length of the stagnant pipe is determined by the application of the fountain device. That is, when the fountain from one of the fountain pipes 11 is intended as shown in FIG. 2 (see FIG. 3 (a)), the squirt pipe 17 is also fountained and a plurality of fountains are aimed. Is shortened (see FIG. 4A). The same amount of water that has flowed out of the fountain 12 is fountained and falls to the fountain 12. Accordingly, the amount of the retained water Wb in the fountain device 12 does not change and is retained in the initial state.

When the stored water Wa in the water storage chamber 13 disappears due to the fountain, one fountain is completed (see the one-dot chain line in FIG. 2A). When the fountain ends, the length of the fountain pipe 11 is equal to or less than the water level difference ΔH (= water level of Wb−water level of Wc) between the accumulated water Wb and the discharged water Wc, so that all the accumulated water Wb is discharged into the water collection chamber 14. Is done. The water collection chamber 14 stores discharged water Wc that is a combination of the stored water Wa and the accumulated water Wb. After discharging the accumulated water Wb, the fountain tube B is turned over to prepare for the re-fountain.

FIG. 2B is an explanatory diagram of the process of turning the fountain cylinder B upside down and returning the discharged water Wc to the water storage chamber 13. In FIG. 2 (b), the water level immediately after being inverted is indicated by a solid line, and the state in which all the discharged water Wc has been discharged is indicated by a one-dot chain line. The discharged water Wc collected in the water collecting chamber 14 flows down the ventilation pipe 15 b and is discharged to the water storage chamber 13, and the amount of water exceeding the inflow hole 17 a of the water collecting pipe 17 flows down the water collecting pipe 17 and enters the water collecting chamber 16. The accumulated water Wb is retained water Wb, and the amount of water below the injection hole 17a of the stagnant pipe 17 is stored water Wa.

Since the accumulated water Wb is stored below the outflow hole 16a of the stagnant water chamber 16, the discharged water Wc does not leak out from the fountain tube B. When the fountain cylinder B is turned upside down again from this state (see FIG. 2C), the accumulated water Wb stored in the water stagnation chamber 16 flows out from the outflow hole 16a at the lower part of the water stagnation chamber 16 and the lower part of the fountain unit 12 It returns to its original state (see Fig. 1 (a)) and the fountain starts.

The above is a description of the sealed type and open type fountain apparatus according to FIGS. 1 and 2. Here, assuming that the upper part of the fountain chamber 2 above the sealed type in FIG. Even if the first fountain occurs, the fountain does not occur after re-inversion because there is no stagnant water Wb. In order to make a fountain, water must be poured into the fountain chamber 2 anew. In the open fountain apparatus of the present invention, this new water pouring is automatically carried out by the outflow of water from the water-stagnation chamber 16 to enable fountains again.

The method of fountain in the air by the circulation of water and air according to the natural principle without using a pump enables a tabletop fountain device that can be moved easily and has a sense of openness regardless of installation location, and it can be used as a toy or figurine It is expected.

It is explanatory drawing of the conventional sealed fountain apparatus. It is explanatory drawing of the open type fountain apparatus of this invention. 2 is an explanatory diagram of Embodiment 1. FIG. FIG. 6 is an explanatory diagram of Example 2.

Example 1 is an open type fountain device that fountains from the center of the fountain, and will be described with reference to FIG. 3 (a) is a perspective view of an open-type fountain cylinder C, FIG. 3 (b) is a plan view thereof, FIG. 3 (c) is a normal sectional view thereof, and FIG. It is sectional drawing. The open-type fountain cylinder C is inverted when the fountain is over, and after a period of time for returning the fountained water, that is, after taking “interval”, the fountain cylinder C is inverted again to return to the normal state and resume the fountain.

As shown in FIG. 3C, the open fountain apparatus shown in FIG. 3 is connected to a water storage chamber 23 and a water collection chamber 24 that are sealed under a fountain 22 that is open at the top. In addition, the water fountain 22 has a cylindrical water stagnation chamber 26 that is closed on both sides, the upper end is opened in the fountain 22, and the inflow hole 21a at the lower end is a gap in the lower part of the water storage chamber 23. The fountain pipe 21 is located in the fountain chamber 22, the lower end is opened in the fountain chamber 22, the lower end is located in the lower portion of the water collection chamber 24, and the lower end is located in the water collection chamber 24. Ventilation pipe 25b which is open and has an upper end located above the water storage chamber 23 leaving a gap, and an upper end which opens to the upper portion of the water-stagnation chamber 26. The lower end inflow hole 27a is above the inflow hole 21a of the fountain pipe 21. A fountain cylinder C in which a water-spilling pipe 27 located at the position is arranged. The water fountain 22 has transparency, and the water collection chamber 24 has a larger capacity than the water storage chamber 23.

When the water storage chamber 23 is filled with the stored water Wa and then the accumulated water Wb is poured into the fountain device 22 (see the solid line in FIG. 3C), the accumulated water Wb passes through the water flow pipe 25a and the water collecting chamber 24. The same amount of air is pushed out to the water storage chamber 22 through the ventilation pipe 25b and the air pressure is increased, and the stored water Wa is pushed up to the fountain pipe 21 to start fountain. Although the stagnant pipe 27 also has an effect of pushing up the stored water Wa, the stagnant pipe 27 is connected to the upper part of the stagnant chamber 26 and is sufficiently long. The stored water Wa cannot be pushed up to the upper end of the water and cannot be ejected.

The fountain from the fountain pipe 21 blows up high initially, but gradually decreases with the passage of time, and when there is no stored water Wa in the water storage chamber 23, one fountain ends (see the one-dot chain line in FIG. 3C). When the fountain ends, the length of the fountain pipe 21 is equal to or less than the water level difference ΔH between the accumulated water Wb and the discharged water Wc, so that all the accumulated water Wb is discharged into the water collecting chamber 24. The water collection chamber 24 stores discharged water Wc that is a combination of the stored water Wa and the accumulated water Wb. After discharging the staying water Wb, the fountain cylinder C is turned over to prepare for the re-fountain.

FIG. 3D is an explanatory diagram of a process of turning the fountain cylinder C upside down to return the discharged water Wc to the water storage chamber 23 and the water-stagnation chamber 26. The discharged water Wc collected in the water collecting chamber 24 (see the solid line in FIG. 3 (d)) flows down the ventilation pipe 25b and is discharged into the water storage chamber 23, and the amount of water exceeding the inflow hole 27a of the water collecting pipe 27 is stagnant. The pipe 27 flows down and is stored in the water-stagnation chamber 26 to become the stagnant water Wb, and the inflow hole 27a and below of the water-spilling pipe becomes the stored water Wa. Although the upper portion of the fountain device 22 is open, the drainage water Wc does not leak out from the fountain tube C because the water-stagnation chamber 26 is installed.

When the fountain cylinder C is turned upside down again from this state, the accumulated water Wb stored in the water stagnation chamber 26 flows out from the outflow hole 26a below the water stagnation chamber 26 and spreads below the fountain device 22 as shown in FIG. The fountain starts after returning to the original state.

Example 2 is an open-type fountain device that fountains from a plurality of locations, and will be described with reference to FIG. 4 (a) is a perspective view of the fountain tube D, FIG. 4 (b) is a plan view thereof, FIG. 4 (c) is a sectional view thereof in a normal state, and FIG. 4 (d) is a sectional view thereof in an inverted state. is there. The open-type fountain cylinder D is turned over when the fountain is over, and after a while, it is turned over again to return to the normal state to resume the fountain.

As shown in FIG. 4 c, the open-type fountain cylinder D shown in FIG. 4 is composed of a fountain device 32, a water storage chamber 33, a water collection chamber 34, and a retention chamber 36, as shown in FIG. The water pipe 35a and the air pipe 35b are arranged in the same manner as the fountain tube C. The water fountain 32 and the water storage chamber 36 are transparent, and the water collection chamber 34 has a larger capacity than the water storage chamber 33. The difference from the fountain cylinder C is that the two stagnation chambers 36 in which the stagnation pipes 37 are incorporated are fixed inside the fountain 32 in the fountain cylinder D, and the protruding part of the stagnation pipe 37 is the fountain pipe 31. It is short at almost the same height as the protruding part.

After the water storage chamber 33 is almost filled with the stored water Wa, when the accumulated water Wb is poured into the fountain device 32 (see the solid line in FIG. 4 (c)), the water flows out into the water pipe 35a. In addition, the water Wa in the water storage chamber 32 is pushed up by the circulation of water and air, and the fountains from the fountain pipe 31 and the two stagnation pipes 37 are started. The fountain from the fountain pipe 31 at the center of the fountain 32 rises in the air, and the two stagnation pipes 37 on both sides fountain so as to hit the ceiling of the stagnation chamber 36.

The fountain is gradually lowered with time, and when the stored water Wa in the water storage chamber 33 is exhausted, one fountain is completed (see the one-dot chain line in FIG. 4C). When the fountain ends, the lengths of the fountain pipe 31 and the stagnant water pipe 37 are equal to or less than the water level difference ΔH between the accumulated water Wb and the discharged water Wc, so that all the accumulated water Wb is discharged into the water collecting chamber 34. The water collection chamber 34 stores discharged water Wc that is a combination of the stored water Wa and the accumulated water Wb. After discharging the accumulated water Wb, the fountain device D is turned over to prepare for the re-fountain.

FIG. 4D is an explanatory diagram of a process of returning the discharged water Wc to the water storage chamber 33 by turning the fountain cylinder D upside down. The discharged water Wc collected in the water collecting chamber 34 (see the solid line in FIG. 4 (d)) flows down the ventilation pipe 35b and is discharged to the water storage chamber 33, and the amount of water exceeding the inflow hole 37a of the water collecting pipe 37 is stagnant. The pipe 37 flows down and is stored in the stagnant water chamber 36 to become the stagnant water Wb, and the inflow hole 37a and below of the stagnant pipe becomes the stored water Wa (see the one-dot chain line in FIG. 4 (d)). Although the upper part of the fountain device 32 is opened, the drainage water Wc does not leak out of the fountain tube D because the water-stagnation chamber 36 is installed. When the fountain cylinder D is turned over again from this state, the water chamber 36 is also turned upside down, and the retained water Wb stored in the water chamber 36 flows out from the outflow hole 36a below the water chamber 36, and the fountain device. It spreads to the lower part of 32, returns to the original state (refer FIG.4 (c)), and a fountain starts.
