Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a filter device for an aquarium fish tank that is placed on the top surface of the aquarium tank and that drains the water in the tank.

<Prior art> A filtering device that is placed on the top surface of an aquarium fish tank to pass through the water in the tank and return it back into the tank has been described in Japanese Utility Model Publication No. 53-22556 proposed by the present applicant. things are known.

The above-mentioned filter device is placed on the top of the aquarium fish tank, and a pump mechanism pumps water in the tank to pass through the layer, allowing the excess water that passes through the layer to fall into the tank from the outlet. It is.

<Problems to be solved by the invention> However, in the overflow device having the above structure, there is a certain height from the liquid level of the water tank to the lower surface of the overflow frame, so the falling force of overflow water is strong. Therefore, the water in the aquarium may splash up from the water surface and scatter to the outside of the aquarium, and the water in the aquarium may rapidly flow downwards at the point where excess water falls, so do not place it on the bottom of the aquarium. Gravel flies around, exposing the bottom and spoiling its appearance. In addition, the rapid flow of water in the aquarium causes aquatic plants and ornaments inside the tank to sway, detracting from its aesthetic appearance. In particular, if the appearance of an aquarium fish tank is impaired, not only will it have no decorative effect even if installed indoors, but conversely, if the fish tank is damaged, it will become extremely unsightly.

<Means for Solving the Problems> The present invention was proposed in view of the above. A through hole is formed in the bottom of the overframe and a drain pipe is installed so as to extend downward. A water receiver with a vertical member on the top surface of the water receiver plate is inserted from below into the lower end of the water receiver plate, and a gap is formed between the lower end of the drain pipe and the water receiver plate of the water receiver, and the drain pipe is removed from the drain pipe. Since the flowing excess water is caught by the water receiver and then allowed to fall into the aquarium, the force of the excess water flowing down from the drain pipe is relaxed and it can fall to the water surface in the aquarium.

<Examples> Examples of the present invention will be described below based on the drawings.

The aquarium fish tank 1 used in the present invention has a frame shape with an open top made of glass on the front, back, left, and right sides.
The filter device 3 of the present invention is placed on the open top portion 2 of the ornamental fish tank 1.

This pumping device 3 is provided with a pump mechanism 5 on one side of a horizontally long overframe 4, and when the pump mechanism 5 operates, the sucked water is raised through a pumping pipe 6, and this water is provided inside the overframe 4. Water is supplied to a water sprinkling pipe 8 extending on the upper surface of the sieve chamber 7 to spray water almost evenly over the entire surface of the sieve chamber 7, and the water that has passed through the sieve chamber 7 is passed through a through hole opened in the bottom part 9 of the sieve frame 4. Aquarium fish tank 1 from 10
It is caused to fall inside. According to the present invention, a drain pipe 11 is inserted and fixed into the through hole 10 formed in the bottom surface portion 9 so as to extend downward from the through hole 10, and a water receiver 12 is installed at the lower end of the drain pipe 11. Insert.

This water receiver 12 has a vertical member 14 provided upright on the upper surface of a disc-shaped water receiver plate 13 having approximately the same diameter as the drain pipe 11, and this vertical member 14 is made up of two vertical plates 1
5 and 15 are fixed in a cross-shaped manner to form a cross-shaped cross section.

The vertical member 14 described above has a tapered shape in which the width at the lower end is slightly longer than the width at the upper end, and the width gradually becomes narrower from the lower end to the upper end. It is wider than the inner diameter of the drain pipe 11, and the width at the upper end is narrower than the inner diameter of the drain pipe 11.

Therefore, the water receptacle 12 described above is connected to the drain pipe 11.
When the vertical member 14 is fully inserted into the drain pipe 11 by inserting it upward from the open lower end of the vertical member 14, the vertical member 14 can only be inserted until the lower part of the vertical member 14 protrudes below the drain pipe 11. A gap 16 is formed between the lower end of the pipe 11 and the surface of the water receiving plate 13, and the water flowing down the drain pipe 11 is discharged and falls from the gap 16. Since the water receiving plate 13 is located at a position that is not much higher than the water surface in the aquarium tank 1, the force of water falling from the gap 16 is extremely reduced and does not damage the plants in the tank.

Although the present invention has been described below with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments described above, and may be implemented in any manner as long as the structure described in the claims for utility model registration is not changed. be able to.

<Effects of the invention> In summary, according to the invention, a through hole is formed in the bottom part of the overframe, a drain pipe is installed so as to extend downward, and a water receiving plate is attached to the lower end of the drain pipe on the upper surface of the water receiving plate. A water receiver with a vertical member is inserted from below, and a gap is formed between the lower end of the drain pipe and the water receiver plate of the water receiver to catch excess water flowing down from the drain pipe. Since the water flowing down the drain pipe is caught by the water receiving plate of the water receiving device, it falls into the water tank. Therefore, the water will not fall forcefully onto the water surface in the aquarium, and the water will not splash up and cause damage to the outside of the aquarium. In addition, the gravel on the bottom of the aquarium does not scatter, and the aquatic plants and decorations do not move around and damage the plants, so the aesthetic appearance is always maintained.

Moreover, it has an extremely simple structure and can be used by simply inserting a water receiver from the bottom end of the drain pipe, and can also be used as is in conventional aquarium fish tanks, so it has extremely high practical value. becomes.
