A fish tank that realizes automatic sewage discharge and purification by adding water

Abstract

The invention discloses a fish tank capable of automatic sewage draining and purification by adding water. The fish tank comprises a fish tank body, a sewage opening is formed in the side wall of an inner cavity of the fish tank body, and an extruding plate is arranged in the inner cavity of the fish tank body; the extruding plate is movably connected with the sewage opening, a central column is fixed to one side, away from an extruding spring, of the extruding plate, and drain holes are formed in a water adding plate and located on the two sides of a bearing spring; inserting pipes are movably inserted in the drain holes and fixedly connected with the central column; inner cavity grooves are formed in the inserting pipes, pulling ropes are symmetrically connected to the water adding plate, and the ends, away from the water adding plate, of the pulling ropes are fixedly connected with a fishing net. The fish tank cannot influence the enjoying angle and sight of people in the process ofenjoying fish in the water tank, it is fundamentally avoided that the aquarium fish is hurt in the sewage draining and water changing process, in the whole sewage draining and water changing process,it is only required that the suitable amount of clear water is added on the water adding plate, the operations are quite simple, the practicability is higher, and the water changing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fish tanks, in particular to a fish tank which realizes automatic sewage discharge and purification by adding water. Background technique [0002] Many households have ornamental fish, and the ornamental fish is placed in the fish tank for breeding. Generally, the fish tank is equipped with a filter system, which is used to pump up the stolen goods floating in the water with the water, and through the function of the filter cotton, the stolen goods stay in the On the filter cotton, the filtering operation is completed, but in actual use, some of the stolen goods will be deposited on the bottom of the fish tank, or the stolen goods that are far away from the suction pipe of the filtration system are difficult to be discharged by the filtration system. The long-term existence of this part of the stolen goods will not only affect the water quality, but also easily Ornamental fish think it is fish food and ea...

AI Technical Summary

Problems solved by technology

[0008] To sum up, in the existing technology, in order to achieve better water exchange and sewage discharge effects in the fish tank, the defects that can be improved are: 1. The sewage structure blocks and affects the viewing sight of the fish in the fish tank; 3. The operation of changing water and sewage is very complicated, and it is impossible to directly add water at one time to realize the operation of changing water and sewage of the whole fish tank, which reduces the efficiency of water change
