Description

Aquarium

Technical Field

The utility model relates to an aquarium with water circulation inside and oxygen filling outside.

Background

With the improvement of the requirements of people on the living quality level, the breeding amount of ornamental fishes in families is gradually increased. Most families generally adopt aquariums for culture, but the aquariums which are generally adopted at present have some problems in the aspects of water oxygen content supplement, water circulation control, noise control and space utilization.

1. The ornamental fish has generally higher requirements on water environment, and the oxygen content in the water is particularly important for the growth of the fish;

2. an air pump is often adopted for oxygenating the aquarium, but because of the reasons of large bubble volume, high floating speed and the like, oxygen filled into a water body cannot be fully combined with water, the oxygenation benefit is low, and the oxygen content in the water is low;

3. the water circulation in the aquarium is poor, and after the aquarium is used for a period of time, the oxygen content in the water body is reduced, the water quality is poor, and the healthy growth of fishes is influenced. When the air pump is used for promoting water circulation, the control is poor, and the normal swimming of the fish is influenced;

4. the water circulation device outside the water tank and the air pump inside the water tank have high noise and have certain influence on the growth of the ornamental fish and the life of people;

5. the air pump is arranged in the fish viewing area, so that the occupied space is large, the pipelines are disordered, and the attractiveness is influenced.

Therefore, an aquarium which has good reliability and low noise and can oxygenate the water in the aquarium through an oxygenation system outside the aquarium and ensure the healthy growth of the cultured aquarium fishes and the normal circulation of the water in the aquarium is needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the aquarium of adopting at present and oxygenate the inefficiency, aquatic oxygen content is low, or adopt case extrinsic cycle and incasement to oxygenate and the hydrologic cycle nature that causes is poor, produces noise and the pleasing to the eye scheduling problem of structure, provides one kind and adopts the incasement circulation, and the case is oxygenated outward, and the noise of production is few, and the circulation that aquatic dissolved oxygen volume is high oxygenates the aquarium.
