Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish tank for various types of fish such as saltwater fish, freshwater fish, 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) Since the water exchange is troublesome as described above, generally, there is a tendency that all the water is exchanged 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. (C) Fish dung and uneaten bait accumulate at the bottom, and the environment of the fish living space 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 tank which can secure a comfortable living space for fish.

[0006] Another object of the present invention is to provide a fish tank which can simultaneously discharge water and excrement of feces and food.

[0007]

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 member and a cock. The container member is made of a translucent material and forms an internal space for storing water. The bottom member is arranged on the bottom side of the container member and closes the internal space on the bottom side. The partition plate member has a large number of through holes in its surface, and is provided across the internal space so as to divide the internal space of the container member into two at a distance from the bottom member. There is. The cock is provided on the bottom member.

[0008]

The container member forms an internal space for storing water, and the bottom member is arranged on the bottom side of the container member and closes the internal space at the bottom side. Therefore, the space formed by the container member and the bottom member. Becomes a water storage space, and water can be stored in this water storage space.

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 space can be seen from the outside of the container member.

Since the cock is provided on the bottom member, when the cock is opened, the water stored in the water storage space is naturally discharged. Conversely, water can be supplied through the cock. This makes it possible to obtain a fish tank in which water can be easily exchanged only by operating the cock.

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

Since the partition plate member has a large number of through holes in its surface, the feces from the fish and the dropped food are passed through the through holes,
The fish can be dropped from the living space side to the bottom member side, which is the non-living space side. As a result, feces and food are separated from the living space of the fish, and a comfortable living space 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 bait falling on the bottom member are discharged at the same time when the cock is opened and the water is exchanged. This allows
With the water exchange, a fish tank can be obtained which can simultaneously discharge feces and food. 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 light-up, etc. 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.
