Silent water injection aerator for fish tank

Abstract

The invention belongs to the technical field of fish tanks, and relates to a silent water injection aerator for a fish tank. The silent water injection aerator is characterized by comprising a bottlebody, an air inlet, a connecting pipe, a one-way valve, a spiral pipe and a breathable film; a liquid inlet is formed in the upper end of the bottle body; the air inlet communicates with the interiorof the bottle body and is positioned at the position close to the liquid inlet; the spiral pipe communicates with the interior of the bottle body and located at the position close to the bottom end ofthe bottle body; one end of the connecting pipe communicates with the wave crest of the spiral pipe, the wave crest at the communicating position of the connecting pipe and the spiral pipe is the wave crest closest to the liquid outlet of the spiral pipe, and the other end of the connecting pipe communicates with the liquid inlet of the bottle body; and the breathable film is arranged at the end,communicating with the spiral pipe, of the connecting pipe. A new technical thought is provided, the structure is simple, use is convenient, and during water injection, silence can be realized, and oxygenation can also be achieved on the fish tank.

Description

technical field [0001] The invention belongs to the technical field of fish tanks, and in particular relates to a silent water injection aerator for fish tanks. Background technique [0002] Fish tanks and aquarium breeding tanks need to change water regularly, filter, and oxygenate again. The existing technology adopts circulating water pumps to realize water changing and filtering. When using circulating water pumps to change water, if the water outlet is installed above the liquid level of the fish tank, although There is a certain oxygenation effect, but there will be a certain amount of noise, especially at night, which will affect rest. If the water outlet is installed below the liquid level of the fish tank, although it can reduce the noise, it does not have the ability to increase oxygen, and another air compressor needs to be used to oxygenate the water through the air pipe inserted into the fish tank, and the two machines work at the same time Many costs will be a...

Problems solved by technology

[0004] The object of the present invention aims at the problems existing in the prior art, and provides a silent water injection aerator for fish tanks. When in use, the device is connected with the water outlet of the circulating water pump and placed below the liquid level of the fish tank. Add oxygen to the fish tank and solve the noise problem when filling water, achieving the effect of one thing with two uses
