Description

Filtration Device for Fishtank}

The present invention relates to a filtration device for a water tank, and more particularly, to a filtration device for a water tank configured to filter foreign substances in water while a water stream generated by floating of air bubbles passes through a filter medium.

Generally, a tank is used to raise fish such as goldfish and tropical fish at home. The water tank is easily contaminated with fish excrement and secretions, so the water is purified through a filtration device.

The water tank filtration device circulates water with a pump and filters out contaminants in the water by installing a filter in the water circulation path. The filtering device is installed inside or outside the water tank, and the filtering device installed inside the water tank is often installed on the bottom or side wall of the water tank.

Korean Patent Registration No. 10-1156799 discloses an aquarium having a filtering function. The aquarium is equipped with a filtration filter and includes a filtration device that sucks and filters water from the habitation area and discharges it to the filtration area.

The conventional aquarium configured as described above uses a pump to circulate water, so the water flow is relatively strong. Therefore, it often interferes with the growth of fish or aquatic plants, and the fry or small fish are sucked into the suction port to die or get injured.

In addition, since the power consumption of the pump is larger than that of the bubble generator in the conventional aquarium and is installed in water, there is a risk of short circuit or electric shock.

In addition, there is a problem in that the filtration filter is easily clogged, so it must be cleaned frequently or the filtration rate is lowered. In other words, if it is too high, the pores are easily clogged by large foreign substances, so the filter needs to be cleaned frequently. Conversely, if the density is low, small foreign substances are not filtered, so the filtration power is reduced.

The present invention has been made from a bird's eye view of the above points, and air is injected into the water to generate air bubbles, and a water flow is generated by the buoyancy of the air bubbles. It is an object of the present invention to provide a filtration device for a water tank that prevents generation and reduces power consumption.
