Abstract

PROBLEM TO BE SOLVED: To provide a water-exchanging apparatus for aquarium fishes capable of exchanging water in water tank for aquarium fishes without consuming much effort and time and without suddenly changing environment of aquarium fishes. SOLUTION: This water-exchanging apparatus is constituted of a water supply tank 1 equipped with a float valve 2 installed on the upper part of a water tank 3 for aquarium fishes, a solenoid valve 4 equipped with a timer attached to a small hole on the side of the water tank 3 for aquarium fishes and a water storage tank 6 installed on the bottom of the small hole of the water tank for aquarium fishes, and the solenoid valve 4 is opened during a set time at a time set by a user and water in the water tank for aquarium fishes is released to the water storage tank 6 and the released water is supplied from the water supply tank 1 to exchange water in the water tank for aquarium fishes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium water changing device for ornamental fish.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned aquarium, the aquarium manager has spent a lot of effort and time to change the water periodically.

[0003] In other words, fish change their condition when the environment changes suddenly. Therefore, it is necessary to spend a long time to change the water, which is troublesome.

[0004] In addition, since water in the aquarium accumulates nitrogen compounds in the excrement of ornamental fish, it must be replaced periodically.

[0005]

SUMMARY OF THE INVENTION There has been a need for an apparatus for exchanging water in an aquarium fish tank without a sudden change in the environment.

[0006]

The present invention employs the following means to solve the above-mentioned problems.

That is, according to the present invention, the water in the ornamental fish tank is discharged into the water tank by installing a solenoid valve with a timer in the water tank and periodically operating the solenoid valve for a fixed time.

When the water level of the ornamental fish tank decreases due to the release, water is automatically supplied to the ornamental fish tank from a water supply tank with a float valve installed above the ornamental fish tank.

By appropriately setting the regular timer, the above-described repetition can be performed, so that the water in the water supply tank with the float valve and the water in the ornamental fish tank can be performed without suddenly changing the environment of the ornamental fish tank.

Therefore, the water tank manager can change the water in the ornamental fish tank simply by disposing of the water in the water storage tank, refilling the water supply tank, and setting a timer according to the size of the ornamental fish tank.

[0011]

[Function] By attaching the above device to the aquarium fish tank,
The aquarium manager can change the water of the ornamental fish tank without spending time and effort, and without abruptly changing the environment of the ornamental fish tank, so that the water quality of the tank can be kept stable.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a combination of the present invention and an ornamental fish tank. In the figure, a small hole is provided on the side of the ornamental fish tank 3, and the small hole is opened and closed by a solenoid valve 4 with a timer 5. In addition, a water storage tank 6 is installed at the bottom of the small hole, and when the solenoid valve with the timer is open, water in the ornamental fish tank is received.

On the other hand, when the water level of the ornamental fish tank decreases, the water supply tank 1 with the float valve 2 supplies water until the water level reaches a certain level.

Therefore, according to the time set by the aquarium fish tank manager, a part of the aquarium fish tank water can be discharged to the water storage tank, and the released water can be supplied from the water supply tank.

[0016]

As described above, according to the present invention, it is necessary to exchange water for a long time and a large amount of labor in an ornamental fish tank without suddenly changing the environment of fish and reducing nitrogen compounds excreted by fish. The feature is that it can be done without spending.

Claims (1)

[Claims] The present invention comprises an electromagnetic valve with a timer, a water supply tank with a float valve, and a water storage tank, and is opened for a set time at a time set by an electromagnetic valve with a timer attached to the aquarium fish tank, and is opened to the water storage tank. The water in the aquarium is released and the water level is lowered by discharging the water, and the released water is supplied from a water tank with a float valve.
