The subject matter relates to air purification technologies, and more particularly, to an air pump with filters.
An aquarium contains aquatic animals and plants, it usually has at least one side made of transparent glass or high-strength plastic. An air pump can draw in external air and output filtered air to the aquarium, and oxygen from the air can be continuously pumped into the water for oxygenation. Therefore, the fresh air can be fed into water in the aquarium by the air pumps, the oxygen from the air is dissolved in the water of the aquarium, resulting in improved oxygen level of the aquarium and sufficient oxygen for fish.
However, the air pumped into the water should be sterilized to avoid viruses or bacteria, and the oxygen output from the air pump ought to be automatically controlled.
An objective of the present disclosure is achieved by providing an air pumping device comprising:
a shell, comprising a receiving cavity located therein, at least one air inlet hole placed at a side wall thereon, and an air outlet hole placed at a bottom plate thereon;
an electromagnetic assembly, which is arranged in the receiving cavity and adjacent to the at least one air inlet hole;
a transmission device, comprises a magnetic element, a swing element, a rotation shaft, and a first transmission element, wherein the swing element is rotatably mounted to the rotation shaft at an end thereof away from the electromagnetic assembly, and the magnetic element is fixed at the other end of the swing element. The first transmission element is arranged between the magnetic element and the rotation shaft and located on a side face of the swing element for moving together with the swing element;
a first air pumping module positioned on either side of the swing element, comprising a piston and a cylinder, wherein the piston is mounted on the transmission element via a Cardan joint to move with the transmission element and create reciprocating movement in the cylinder, the cylinder having a one-way inlet valve and a one-way outlet valve;

In operation, the electromagnetic assembly, powered by external power supply, generates pulsed magnetic forces for driving the magnetic element at intervals, which leads the swing element to swing back and forth. As the transmission element moves with the swing element, the piston connected to the transmission element reciprocates in the cylinder. When the piston moves out of the cylinder, external air is sucked into the cylinder via the one-way inlet valve, when the piston moves inside the cylinder, the air sucked in is pumped out from the cylinder to the sterilizer element via the one-way out valve.
