A pair of upper and lower water inlets 37 are formed on the lower side of the water guide 34 along both sides of the water guide portion 34. The opening 36 and the water intake 37 are formed to a size that does not allow the fish 4 to pass therethrough, but when small fish such as fry are bred in the aquarium 1, a net or the like not shown is used. It is desirable to cover the lower end portion of the water guiding portion 34 by means of the above.

Next, the operation of the above configuration will be described. First, as shown in FIG. 1, after connecting the drainage pipe 9 and the water absorption pipe 10 to both ends of the water circulation path 6, the drainage pipe 9 is inserted through the suction cup 11 so that the discharge port 17 is submerged in the water tank 1. 1 is attached and fixed to the side portion 1A. At the same time, on the opposite side of the drain pipe 9, the water suction pipe 10 is attached and fixed to the side portion 1A of the water tank 1 via the suction cup 11 so that the water guiding portion 34 is submerged in the water tank 1.
In this state, when the circulation pump 8 of the purifying device 5 is started,
The water W in the water tank 1 is sucked up from the opening 36 and the water suction port 37, and the water W is sent out to the water circulation path 6 via the water suction pipe 10.
The dust D and the like contained in the water W is filtered by the filter 6. Then, the purified water W is sent out to the discharge pipe 9 by the circulation pump 8 and is again discharged into the water tank 1 through the opening 18 of the discharge port 17.

In this series of operations, the water W sent to the discharge pipe 9 passes through the upper end of the folded portion 14, and is guided to the lower side of the wall surface of the inclined portion 15 and the end portion 16 as shown by the arrow in FIG. While being guided to the outlet 17. Then, the water W passing through the end portion 16 continues to flow along the lower wall portion 20 of the discharge port 17, and the portion where the water W flows is formed as the discharge path 21 below the discharge port 17. Furthermore, since the water W in the upper part of the discharge path 21 merges and is entrained with the flow of the water W passing through the discharge path 21, the water W near the water surface F in the entire water tank 1 is discharged from the opening 18 together with the dust D. Suction path 22 for sucking the water W in the aquarium 1 into the discharge port 17
Is formed. Therefore, the water W in the suction passage 22 and the discharge passage
Due to the confluence of the water W of 21 with each other, the dust D sucked from the upper portion of the opening 18 is discharged again from the lower portion of the opening 18, and the dust D is widely diffused in the aquarium 1 without staying in one place. . Further, since the outlet 17 is expanded in a funnel shape toward the opening 18, the water W from the opening 18 is appropriately diffused without generating a water flow in one direction in the water tank 1.

The height of the discharge port 17 can be arbitrarily changed depending on the mounting position of the suction cup 11. For this reason,
For example, when many oil films are seen on the water surface F, the position of the discharge port 17 may be adjusted so that the opening 18 is arranged near the water surface F. In addition, the aquarium 1 by raising the nose of fish 4, etc.
When the oxygen deficiency state of the water W in the inside is recognized, the position of the discharge port 17 is adjusted so that the opening 18 is about 1/3 above the water surface F as shown by the alternate long and short dash line in FIG. More air A
If the air is taken in, the air A is entrained with the flow of the water W passing through the discharge passage 21 described above, and an excellent aeration effect is brought about.

On the other hand, on the side of the water absorbing pipe 10, the opening 36 of the water absorbing portion 35 is provided.
Not only is there a plurality of water inlets 37, so water W
A large amount of the dust D is taken in from the opening 36 and the water inlet 37, and by the action of the outlet 17, the water tank 1
The dust D and the oil film of the entire inside circulate in the water tank 1 along with the flow of the water W in the discharge passage 21, so that the dust D in a part of the water tank 1
The water W is efficiently purified without the accumulation of oil film and oil film. Further, even if the opening 36 of the water absorbing portion 35 is clogged with dust D or the like, the water W and the dust D can be collected from the plurality of water suction ports 37.

As described above, according to the above embodiment, the funnel-shaped drainage port 17 is formed obliquely downward at the end 16 of the drainage pipe 9, so that the water W passing under the drainage port 17 is formed. The water W on the upper side of the discharge port 17 merges and is entrained with the flow of water, and the water W and the dust D in the water tank 1 are sucked into the discharge port 17 once, and then the water tank 1 is again discharged from the discharge port 17. Can be diffused throughout. Therefore, this outlet 17
Since the water flow is generated in the entire water tank 1 due to the suction of the water W by the, it is possible to eliminate the problem that the dust D is accumulated in a specific portion as in the conventional case, and the water tank 1 can be sufficiently cleaned. Is possible. Also, the opening of the outlet 17
By moving 18 near the water surface F, it is possible to effectively remove not only the dust D but also the oil film. Moreover, since the discharge port 17 is expanded in a funnel shape toward the opening 18, the water W from the opening 18 can be appropriately diffused without generating a water flow in one direction in the water tank 1.
The aquatic plant 3 does not always move in the same direction, and the aesthetics of the aquarium 1 can be significantly improved.

Further, since the plurality of water inlets 37 formed in the water suction pipe 10 collect a large amount of dust D, oil film and the like diffused throughout the water tank 1, the water W in the water tank 1 is quickly collected.
It becomes possible to carry out the purification of more fully and efficiently.

Further, the following points can be mentioned as effects of the embodiment. First, since the drainage pipe 9 and the water absorption pipe 10 are both made of a transparent material made of glass, there is no discomfort when installed in the water tank 1, and the suction cup 11 is attached from the outside of the side portion 1A of the water tank 1. Since the suction cups 11 are not arranged inside the water tank 1, the appearance inside the water tank 1 can be significantly improved. Further, since the suction cup 11 is attached to the outside of the side portion 1A, the drain pipe 9 and the water suction pipe 10 can be moved easily without putting a hand in the water tank 1. Furthermore, if the suction cup 11 is removed, the drain pipe 9
Also, the water absorption tube 10 itself can be easily cleaned by using chlorine bleaching material for kitchen. Moreover, if the position of the discharge port 17 is adjusted so that the opening 18 is about ⅓ above the water surface F, oxygen in the air A can be supplied to the water W in the water tank 1, resulting in an excellent aeration effect. Bring

Further, the opening of the water absorption portion 35 having a horizontally long shape
Since the water W, the dust D, and the like are collected by the 36 and the plurality of water absorbing portions 37, the dust D is less likely to be clogged, and the motor constituting the circulation pipe 8 is less likely to be burdened. Moreover, even if the opening 36 is clogged with dust D or the like, the water W and the dust D can be collected from the plurality of water inlets 37, so that there is no fear that the purification capacity will be deteriorated.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, a carbon dioxide supply device may be provided in the aquarium in order to promote the growth of aquatic plants. In this case, it is also possible to bring about an effect that carbon dioxide which tends to dissolve in water diffuses in the entire water tank by the circulation action of water by the discharge port.
