Ornamental fish tank internally provided with water replacement system

Abstract

The invention discloses an ornamental fish tank internally provided with a water replacement system, and relates to the field of ornamental fish culture. The ornamental fish tank comprises a fish tankbody and the water replacement system, wherein the upper end of the fish tank body is provided with an opening, the water replacement system comprises a controller, a water tank, an oxygen pump, a residual chlorine sensor, a water suction pump and a water level sensor, the two sides of the water tank are provided with clamping claws, the water tank is fixed above the opening through the clampingclaws, the water tank is provided with a water inlet, one end of the outer side of the water tank is provided with the oxygen pump, an air outlet of the oxygen pump is communicated with the inner portion of the water tank through an air outlet hose, the end, close to the oxygen pump, of the inner portion of the water tank is fixedly provided with the residual chlorine sensor, the end, away from the oxygen pump, of the inner portion of the water tank is fixedly provided with the water suction pump, a water flow outlet of the water suction pump extends out of the water tank, and the bottom faceof the fish tank body is fixedly provided with the water level sensor. The ornamental fish tank with the built-in water replacement system has the advantages that the chlorine content of the water quality of the water added during daily water replacement of ornamental fish is reasonably controlled through the water replacement system; when water is added, the water level can be automatically controlled to reach a set standard water level, thereby preventing the water level from being too high or too low.

Description

technical field [0001] The invention relates to the field of ornamental fish cultivation, in particular to an ornamental fish tank with a built-in water exchange system. Background technique [0002] Ornamental fish refer to fish with bright colors or peculiar shapes that have ornamental value. Breeding ornamental fish is a way of leisure and entertainment, which can cultivate sentiment, create a green environment, beautify life and so on. As the saying goes, "Fish farming first raises water", the quality of water directly determines the ornamental value of ornamental fish to a large extent, in order to maintain a good water quality environment, it is essential to change the water, including water absorption and water addition, for For ordinary people to raise ornamental fish, subject to the limitation of conditions, tap water is commonly used to add water, but in order to achieve the purpose of water purification, the tap water we drink is added with "chlorine" when it leav...

As the saying goes, "Fish farming first raises water", the quality of water directly determines the ornamental value of ornamental fish to a large extent, in order to maintain a good water quality environment, it is essential to change the water, including water absorption and water addition, for For ordinary people to raise ornamental fish, subject to the limitation of conditions, tap water is commonly used to add water, but in order to achieve the purpose of water purification, the tap water we drink is added with "chlorine" when it leaves the factory, which can kill various bacteria in the water. Such as Escherichia coli, because chlorine can slowly volatilize in the air, and the amount added is set according to human standards, so we can directly boil it and drink it, but this amount may be fatal to ornamental fish, serious It will directly lead to the sudden death of ornamental fish, or cause the organ failure of ornamental fish, and slightly affect the hair color of ornamental fish. Therefore, the tap water cannot be directly used to raise ornamental fish in theory without treatment. The tap water needs to be exposed to sunlight or oxygen. Pumping oxygen, the former takes a long time, while the latter requires more professional equipment. At the same time, there are requirements for the water level when adding water. The water level should not be too low or too high, let alone overflow the fish tank.
