Double layer purification type half-open small-sized office table fish tank

Abstract

The invention discloses a double layer purification type half-open small-sized office table fish tank. The fish tank comprises a main tank body and an auxiliary purifying and oxygenation tank body which are integrated into a whole. The double layer purification type half-open small-sized office table fish tank is provided with a double filtration device so as to realize bottom filtration and upper-layer plant purification filtration, so that the limpidity of a water body is guaranteed, the cleaning period is prolonged, and the water changing frequency is reduced; and the double layer purification type half-open small-sized office table fish tank is provided with the double filtration device and an oxygenation device, and the double filtration and the oxygenation can be realized by only onewater pump, so that a common oxygenation pump for household cultivation of aquarium fish is omitted, and the consumption of electric energy is reduced.

Description

technical field [0001] The invention relates to a desk fish tank, in particular to a double-layer purified semi-open small desk fish tank. Background technique [0002] At present, common fish tanks on the market are divided into two categories, one is a fish tank for large-scale places; the other is a fish tank for families, offices and other places. Among them, the fish tanks used in places such as homes and offices are relatively large in size and occupy a large space, but specific places often cannot meet this condition. Moreover, currently on the market, the two common types of fish tanks need to be equipped with certain special oxygenation and filtration devices in order to realize the oxygenation and filtration functions. [0003] However, in many places, limited by the local environment, it is inconvenient to use the two commonly used types. [0004] At present, the common aeration device on the market is realized by the aeration pump; the aeration pump presses the...

Problems solved by technology

But in this way, the filter cotton is easy to be blocked, and the cleaning cycle is short; the water pump cannot "automatically" extract all the residue at the bottom, and when the water pump is pumping the water body, the residue is crushed, causing secondary pollution to the water

[0007]3. As far as the circulation system is concerned: the water is pumped by the water pump to the filter box with filter cotton placed above the fish tank, and then drips down. single function

However, due to the accumulation of residues in this place, the lack of dissolved oxygen, and the low reproduction rate of nitrifying bacteria, the water body is easily turbid and the cleaning cycle is short, which is not conducive to the growth of ornamental fish. The resistance of ornamental fish will decrease, and they will get sick and even die.

[0009]In short, the current fish farming devices on the market all have the disadvantages of low dissolved oxygen, poor filtering effect and short cleaning cycle, so it needs to be improved
