Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to saltwater fish, freshwater fish,
The present invention relates to a fish tank for various types of fish such as tropical fish or ornamental fish.

[0002]

2. Description of the Related Art As is well known, a conventional fish tank of this type is made of a transparent glass or plastic material and is composed of a container having a bottom and a side wall integrated with each other.

[0003]

However, the conventional fish tank has the following problems. (A) When replacing the water in the aquarium, the water must be pumped out of the container through the upper opening to reduce the weight, then transported to the sink and drained of the water remaining in the fish tank.
Then, after this, the working procedure of pouring new water must be taken. Therefore, it takes a long time to replace the water, and the work is very troublesome. This drawback becomes more remarkable as the water tank becomes larger. (B) When cleaning the aquarium, it is necessary to scoop the fish with a net or hands and transfer it to another container. In such a case, the larger the aquarium is, the more difficult it is to catch and transfer fish. In addition, it will damage the fish to a large extent and impair the health of the fish. In the worst case, it can be fatal to the fish. For this reason, when the fish is an expensive ornamental fish or a tropical fish which is vulnerable to environmental changes, the fish transfer work requires extremely careful attention. (C) Since the replacement of water is troublesome as described above, there is generally a tendency to replace all the water at once. For this reason, sudden changes in the environment, especially changes in water temperature, cause the fish to catch a so-called cold, which shortens the life of the fish. (D) Fish droppings and uneaten food accumulate on the bottom, and the environment of the fish breeding area deteriorates over time. This shortens the life of the fish.

[0004] Therefore, an object of the present invention is to provide a fish tank capable of easily exchanging water.

Another object of the present invention is to provide a fish aquarium that can easily transfer fish during cleaning of the aquarium and can minimize damage to the fish.

[0006] Another object of the present invention is to provide a fish tank which can secure a comfortable breeding area for fish.

[0007] Another object of the present invention is to provide a fish tank which can discharge feces and foods at the same time as water exchange.

[0008]

To solve the above problems, a fish tank according to the present invention comprises a container member, a bottom member, and
It includes a partition plate member, a drainage means, and a fish discharge pipe. The container member is made of a translucent material and forms an internal water storage region. The bottom member is arranged on the bottom side of the container member and closes the inner region on the bottom side. The partition member has a large number of through holes in its surface, and is provided across the inner region so as to divide the inner region of the container member into two at a distance from the bottom member. There is. The drainage means is provided in the bottom member. The fish discharge pipe communicates with the inner region above the partition member and can be opened and closed. The container member forms a water storage inner region, and the bottom member is disposed on the bottom side of the container member. Since the inner region is closed on the bottom side, the region formed by the container member and the bottom member serves as a water storage region, and water can be stored in this water storage region.

The container member is made of a translucent material, and fish such as saltwater fish, freshwater fish, tropical fish or ornamental fish swimming in the water stored in the water storage area can be seen from the outside of the container member.

Since the drain member is provided in the bottom member,
When the drainage means is opened, the water stored in the water storage area is naturally discharged. On the contrary, water can be supplied through the drainage means. This makes it possible to obtain a fish tank in which water can be easily exchanged only by operating the drainage means.

Since the fish discharge pipe can be opened and closed and communicates with the inner region of the upper part of the partition plate member, when the fish needs to be transferred during the cleaning work of the water tank, the fish discharge pipe is discharged. The tube can be opened and the fish can be directly transferred to a separately prepared container such as a bucket. During this time, the fish will not come into contact with the net or hands. Therefore, the fish can be easily transferred, and damage to the fish can be minimized.

Since the partition plate member is provided across the inner region at a distance from the bottom member so as to divide the inner region of the container member into two parts, of the inner region divided by the partition member. The inner region opposite to the bottom member side can be used as a breeding region for fish.

Since the partition plate member has a large number of through holes in its surface, the feces discharged from the fish and the dropped food are passed through the through holes.
It can be dropped from the fish breeding area side to the bottom member side which is the non-breeding area side. As a result, feces and food are separated from the fish breeding region, and a breeding region that is comfortable for the fish is secured above the partition member. The size and number of the through holes are set to values that can prevent fish from passing through the through holes and are suitable for passing feces and food.

The feces and food falling on the bottom member are discharged at the same time when the drainage means is opened and the water is exchanged. As a result, it is possible to obtain a fish tank capable of discharging feces and food at the same time as water exchange. Regular water exchange prevents the accumulation of feces and food and keeps the fish tank clean.

Since the partition plate member has a large number of through holes in the surface and is provided at a distance from the bottom member, the air piping for generating bubbles, the light-emitting body for lighting up, and the like are provided within the space. It can be fixed to the partition plate member by a stopper that is placed on the through hole and is hung on the through hole. Further, the through holes allow the bubbles to be made uniform in size. Further, by guiding the light emitted from the light-emitting body through the through hole, it is possible to obtain an illumination effect as if illuminated by a plurality of light rays.
