Abstract

<P>PROBLEM TO BE SOLVED: To provide a filter device for a water tank of aquarium fish brought to have beauty effect in the water tank and to widely use the water tank, and enhanced in filtration efficiency of an air-lift type filter of the water tank of aquarium fish. <P>SOLUTION: The filter device is constituted by installing a filtration chamber having a filter medium on the opening of the water tank for aquarium fish or bringing the chamber to be installed, forming an air stone for generating bubbles for air-lift on a lid installed in the upper part of the filtration chamber, installing a pipe for passing the bubbles generated in the air stone to a waterweed bowl installed on the bottom of the tank, installing the air stone in the air guide pipe installed in the waterweed bowl, pumping up water in the lower part of the water tank by the air stone installed to the lid of the filtration chamber and by the air bubble guide pipe installed to the waterweed bowl, filtering the water through the filter medium in the filtration chamber and returning filtered water to the water tank. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

The present invention is an air lift type filter for an aquarium fish tank, in which the filtration chamber can be installed or installed at the upper opening of the aquarium, and air for generating air lift bubbles on the lid provided at the upper part of the filtration chamber The stone pot is installed on the bottom of the aquarium with a bubble induction pipe that allows air bubbles generated by the air stone to pass through. The air stone is installed in the bubble induction pipe provided in the water plant pot, and the filtration chamber. The air stone provided on the lid of the water tank and the bubble induction pipe provided on the aquatic plant pot pump up the water at the bottom of the water tank to the filtration chamber by the air lift effect, filter it through the filter medium placed in the filtration chamber, and filter the filtered water into the water tank. Filter the water in the return tank.

In addition, a filtration chamber can be placed in the aquarium pot installed at the bottom of the aquarium, and a filter installed at the top of the aquarium and a filtration medium placed in the aquarium bowl at the bottom of the aquarium. And the water in the tank can be filtered at the bottom.

Furthermore, the aquarium fish tank filter is characterized by installing a filter with a bubble induction pipe attached to the bottom of the aquarium and filtering water at the upper and lower parts of the aquarium.

Conventionally, an air lift filter has been installed and used on the bottom surface of a water tank, but this has been detrimental to the beauty of the water tank.

In the present invention, by installing the filtration chamber in the upper part of the water tank, the inside of the water tank can be used widely and the aesthetics can be maintained.

Furthermore, since the water pumped up by the air lift is received by the filter medium in the filter chamber, fish droppings and trash can be reliably received.

Furthermore, the filtration efficiency is increased by installing a filtration chamber on the bottom of the water tank.
