connected to.

Next, the operation of this embodiment will be explained with reference to FIG. 7 facing the corner 2.
In this state, first, as shown by the arrow Pa in FIG. 5a, one of the mounting 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 arrow Pb in FIG. 5b, the other mounting portion 10 is pressed toward the other side surface 1b so that the suction cup 4 is attracted to the side surface 1b. At this time, the angle formed by both mounting parts 9 and 10 is 1 on both sides.
Since the angle is slightly larger than the angle formed by a and 1b, one of the mounting parts 9 has its front wall 8 side end in contact with the side surface 1a, and the connecting part 11 side is separated from the side surface 1a,
The pressure in the sealed space between the suction cup 4 and the side surface 1a of the attachment portion 9 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 1
0 is the suction cup 4 on the mounting part 9 side, as shown in FIG.
Due to the suction force on the side surface 1a, the end portion on the front wall 8 side is brought into contact with the side surface 1b, and the connecting portion 11 side is separated from the side surface 1b. As a result, the suction cup 4 is
The pressure in the sealed space between the side surface 1b and the side surface 1b is reduced, and the suction cup 4
The adsorption force becomes large, and the attachment part 10 is reliably attached to the side surface 1b.

In this installation state, the ends of the mounting parts 9 and 10 on the back wall 7 on the front wall 8 side are in close contact with both side surfaces 1a and 1b of the water tank 1, and the space between the water pipe 3 and the corner part 2 is small. Closed. Therefore, ornamental fish are reliably prevented from entering between the water pipe 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. This also prevents ornamental fish from entering between the water pipe 3 and the aquarium 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 conduit 20; Water flow occurs. This rising water flow includes water that passes through the filter member 5 from the water intake port 15 and flows into the water conduit 20, and water that passes through the water intake port 15 and flows into the water conduit 20
Water flowing into the water conduit 20 from the water inlet 15 passes through the filter member 5 at an appropriate speed and is purified.
The water flows back into the water tank 1. In other words, 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 these aerobic microorganisms can promote the growth of ornamental fish. Decomposes organic matter such as leftover feed and feces to prevent clogging of the filter member 5, and
It becomes possible to provide chlorella and the like as live bait for ornamental fish.

In addition to the hose 22, the housing groove 17 provided in the back wall 7 of the water conduit 3 can also house a cord for a thermostat or the like installed in the water tank to adjust the water temperature.

FIG. 6 shows another embodiment of the present invention, in which a flat casing 27 having a plurality of water inlets 26 is buried in gravel 25 spread inside the aquarium 1. A pump P leading to the water tank 1 is installed at the bottom of the water tank 1 corresponding to the corner 2 of the water tank 1.

The filtering member is omitted from the water guide pipe of the previous embodiment, and the lower end of the water guide pipe 3a is made into a hollow cylinder shape and connected to the pump P, and the water guide pipe 3a is attached closely to the corner part 2 as in the previous embodiment. It will be done.

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

As yet another embodiment of the present invention, as shown in FIG. 7, the lower end of a water guide pipe 3b having basically the same structure as the water guide pipe 3a is connected to the casing 27, and the upper end of the water guide pipe 3b is connected to the casing 27. A pump P may be provided, and in this case as well, the water guide pipe 3b can be attached closely to the corner 2 of the aquarium 1, thereby preventing ornamental fish from entering between the aquarium 1 and the water guide pipe 3b. can do.

C. Effects of the Invention As described above, according to the present invention, a pair of mounting portions forming an angle slightly larger than the corner portion of the aquarium are connected by a connecting portion, and the mounting portions are arranged facing the corner portion side. The back wall has a cross-sectional shape in which a back wall facing the inner side of the aquarium and a front wall facing the inner side of the aquarium are connected to form a closed cross section, and the back wall is attached to the two sides of the aquarium forming the corner portion. Since suction cups are fixed on the outside of both mounting parts, the end of the mounting part on the front wall can be brought into close contact with the two sides of the aquarium, and the water guide pipe can be securely attached to the aquarium using the suction cups. Entrance between the water tank and water pipes is reliably prevented.
