Aquarium oxygenation pump structure

Abstract

The invention discloses an aquarium oxygenation pump structure. The aquarium oxygenation pump structure comprises a cylindrical hollow cylinder body, leather cups, an air inlet valve and an air outlet valve, wherein the leather cups are connected with the cylinder body; and the air inlet valve and the air outlet valve are respectively arranged on the side wall of the cylinder body. The aquarium oxygenation pump structure is characterized in that: an electromagnet consisting of an iron core fixed in the cylinder body and a coil fixed on the outer wall of the cylinder body is arranged in the middle of the cylinder body; the number of the leather cups is two and the two leather cups are symmetrically arranged at the two ends of the hollow cylinder body; two permanent magnets having the same magnetic pole direction are respectively arranged in the centers of the inner sides of the two leather cups; the electromagnet and the magnetic field lines in the centers of the two permanent magnets are on the same straight line; and the two leather cups are driven in a way that the electromagnet with alternating current drives the two permanent magnets to reversely move. The force of the two permanent magnets on the iron core of the electromagnet is balanced, the permanent magnets are arranged on the leather cups, and the leather cups absorb a part of vibration energy while being driven by the permanent magnets, so the mechanical vibration generated by the whole oxygenation pump is very low.

Description

technical field [0001] The invention relates to the structural technology of an aquarium aeration pump. Background technique [0002] Most of the aquarium aeration in the prior art directly utilizes the alternating magnetic field generated by the 50 Hz mains to pull a permanent magnet to reciprocate to drive the lever connected to it to swing, and the lever is connected to the compressed air cylinder to work. The disadvantage is that one end of the lever Connected to the base of the aeration pump, the high-frequency swing of the lever produces a lot of mechanical noise; while some DC aeration pumps simply use the motor to drive the compression cylinder with the piston to work. The disadvantage is that the piston is in the cylinder. The friction created by the reciprocating motion wastes energy. Contents of the invention [0003] The purpose of the present invention is to propose an aquarium aeration pump structure with low mechanical vibration and noise, so as to overco...
