(3) Examples Examples of the present invention will be explained below with reference to the drawings.
First, in FIG. 1 showing an embodiment of the present invention, an aquarium 1 for rearing goldfish, tropical fish, saltwater fish, etc. before appreciation is formed in a box shape, and two orthogonal sections of this aquarium 1 are shown. A water pipe 3 is attached to a corner portion 2 formed by two side surfaces 1a and lb.

With reference to FIGS. 2, 3, and 4, the water conduit 3
is basically formed into a cylindrical shape with a bottom made of synthetic resin, for example, and its cross-sectional shape consists of a back wall 7 facing the corner 2 side and a back wall 7 facing the corner 2 side, and the inner side of the water tank 1. The facing wall 8 forms a closed cross section and is connected to the front wall 8 .

The back wall 7 is formed by connecting a pair of attachment parts 9.10 with a connecting part 11, and the re-attachment part 9.10 is made by changing the angle α between them to the angle made by the sides 1a and lb of the aquarium 1, i.e. 90
The connecting portion 11 is arranged in a slightly larger shape than the angle 2, and the connecting portion 11 is formed in a circular arc shape convexly curved toward the corner portion 2 side. On the other hand, the front wall 8 is formed into a trapezoid shape that narrows toward the inside of the water tank 1.

A drain port 12 opening toward the inside of the water tank 1 is provided at the upper end of the water guide pipe 3, and an auxiliary water intake port 14 is bored in the bottom wall 13 of the water guide pipe 3. Further, in the lower part of the surface wall 8 of the water conduit 3, there are a plurality of slit-shaped water intake ports 1 spaced apart vertically.
5 is drilled.

On the other hand, in the back wall 7 of the water conduit 3, a pair of recesses 16 are provided on the outer surface of the reattachment portions 9 and 10, spaced apart from each other in the vertical direction, and a housing groove 17 is provided in the connection portion 11.

Moreover, the accommodation groove 17 is arranged to extend vertically from the upper end of the water pipe 3 to near the bottom.
The upper end is open upward, and the lower end of the housing groove 17 is provided with an end wall 18 facing upward. Furthermore, this end wall 18
A hole 19 communicating with the inside of the water conduit 3 is bored in the hole 19 .

A suction cup 4 is fixed to each recess 16 of the reattachment parts 9 and 10, and the base of the suction cup 4 is attached to the attachment part 9.1.
0 is engaged. Moreover, the tip of each suction cup 4 is the mounting part 9.1
Projects outward from the outer surface of 0.

A columnar filter member 5 having a cross-sectional shape substantially corresponding to the cross-sectional shape of the front wall 8 is housed and arranged in the water conduit 3 so as to be biased towards the front wall 8 side. Thereby, in the water conduit 3, a conduit 20 extending over the entire length of the conduit 3 is defined between the back wall 7 and the filter member 5, the upper end of this conduit 20 is connected to the drain port 12, and the lower end is connected to the drain port 12. is connected to the auxiliary water intake port 14.

At the lower part of the water conduit 20, an air injection member 6 formed into a cylindrical shape and made of a breathable material such as a foamable synthetic resin is disposed. This air injection member 6 is integrally provided with a small diameter connecting pipe 21, which projects from the hole 19 into the housing groove 20.

One end of a hose 22 is connected to the air pump P of the water tank 1.
7 , extends downward within the housing groove 17 , and is connected to the connecting pipe 21 of the air injection member 6 .

Next, the operation of this embodiment will be explained with reference to FIG. 5. When attaching the water pipe 3 to the water tank 1,
The back wall 7 is made to face the corner part 2 so that the drain port 12 corresponds to the water surface in the water tank 1.

In this state, first, as shown by the arrow Pa in FIG. 5(a), one of the attachment parts 9 is pressed toward one side surface 1a of the aquarium 1 so that the suction cup 4 is attracted to the side surface 1a.

Next, as shown by the arrow pb in FIG.
so that it sticks to the side surface 1b.

At this time, the angle formed by both mounting parts 9 and 10 is both sides 1a,]
,b is slightly larger than the angle of the angle between the front wall 8 and the side surface 1a, so that the coupling portion 11 side of the attachment portion 9 separates from the side surface 1a while the end on the front wall 8 side is in contact with the side surface 1a, and the suction cup 4 of the attachment portion 9 The pressure in the sealed space between the side surfaces 18 is reduced. Therefore, the suction force of the suction cup 4 becomes large, and the attachment part 9 is reliably attached to the side surface 1a.

When the pressing state of the mounting part 10 is released, the mounting part 10 brings the end of the front wall 8 into contact with the side surface 1b due to the suction force of the suction cup 4 of the nine mounting parts to the side surface 1a, as shown in FIG. The connecting portion 11 side is separated from the side surface 1b after being brought into contact with each other. As a result, the airtight space between the suction cup 4 and the side surface lb is depressurized in the same way as described above, and the adsorption force of the suction cup 4 is increased, so that the mounting portion 10 is attached to the side surface lb.
It can be securely attached to b.

In this mounting state, each mounting portion 9 on the back wall 7,
The front wall 8 side end portion of 10 is in close contact with both side surfaces la and lb of the water tank 1, and the space between the water conduit 3 and the corner portion 2 is closed. Therefore, it is reliably prevented that the water before viewing enters between the water conduit 3 and the aquarium 1. Moreover, since the hose 22 is accommodated in the housing groove 17 provided in the back wall 7, it is possible to bring the back wall 7 closer to the corner 2, thereby further reducing the gap between the corner 2 and the back wall 7. It can be made smaller, and this also prevents the water before viewing from entering between the water pipe 3 and the water tank 1.

When pressurized air is supplied from the air pump P to the air injection member 6 with the water conduit 3 attached to the water tank 1, air bubbles generated in the air injection member 6 rise within the water conduit 20; Water flow occurs. This rising water flow is formed by water that passes through the water intake port 15 and flows into the water conduit 20 through the filter member 5, and water that flows into the water conduit 20 from the auxiliary water intake port 14. The water is purified by passing through the filter member 5 at an appropriate speed, and then flows back into the water tank 1 through the drain port 12. That is, by providing the auxiliary water inlet 14, the speed of water passing through the filter member 5 is adjusted to an appropriate value to promote the reproduction of chlorella and aerobic microorganisms, and the aerobic microorganisms By decomposing organic matter such as leftover feed and feces, it is possible to prevent clogging of the filter member 5 and to serve chlorella and the like as raw rice cakes before viewing.

In addition to the hose 22, the accommodation groove 17 provided in the back wall 7 of the water conduit 3 can also accommodate, for example, a cord such as a thermostat installed in the water tank for adjusting the water temperature.

FIG. 6 shows another embodiment of the present invention, in which the aquarium 1
A flat casing 27 having a plurality of water intake ports 26 is buried in the gravel 25 spread inside, and a pump P communicating with the inside of the casing 27 is connected to the corner 2 of the aquarium 1. installed at the bottom.

The lower end of the water guide pipe 3a, which is made into a hollow cylinder by omitting the filtering member from the water guide pipe of the previous embodiment, is connected to the pump P, and the water guide pipe 3a is closely connected to the corner part 2 as in the previous embodiment. Installed.

In this embodiment as well, ornamental colors are prevented from entering between the water conduit 3a and the aquarium 1, as in the previous embodiment.

As yet another embodiment of the present invention, as shown in FIG.
b may be connected to the casing 27 at the lower end, and the pump P may be disposed above the water pipe 3b. In this case as well, the water pipe 3b may be attached closely to the corner 2 of the water tank 1. This makes it possible to prevent ornamental colors from entering between the aquarium 1 and the water conduit 3b.

C2 Effect of the Invention As described above, according to the present invention, a pair of mounting parts forming a slightly larger angle than the corner of the aquarium are connected by a connecting part, and the mounting part is arranged facing the corner. a back wall,
The outer surface of the reattachment part of the back wall has a cross-sectional shape in which the front wall facing the inner side of the aquarium is connected to form a closed section, and the outer surface of the reattachment part of the back wall is attached to the two sides of the aquarium forming the corner part. Since a suction cup is fixed to each side, the end of the mounting part on the front wall side can be brought into close contact with the two sides of the aquarium, and the water pipe can be securely attached to the aquarium using the suction cup.
