Two-way electromagnetic-driven air compressor

Abstract

The invention belongs to the technical field of air compressors, and relates to a two-way electromagnetic-driven air compressor. The two-way electromagnetic-driven air compressor comprises a cylindrical cylinder block, and a piston in the cylinder block; cylinder covers are arranged in openings at the two ends of the cylinder block; each cylinder cover is provided with an intake way with an intake one-way valve, an exhaust way with an exhaust one-way valve and an electromagnetic driver; a piston rod connected to the piston extends out from the cylinder covers at the two ends of the cylinder block, and extends into the corresponding electromagnetic drivers; and the electromagnetic drivers on the two sides of the cylinder block are electrified to apply force in the same direction to drive the piston rod and the piston to move back and forth, so that gas is fed from the intake way, and compressed gas is output from the exhaust way. The two-way electromagnetic-driven air compressor has the advantages of high power, high efficiency, low size, low noise and saving of electric energy, and is suitable for providing compressed air to the society.

[0002] Chinese patent CN 205025732 U discloses "An Electromagnetic Air Compressor", which includes a tank shell, an energy storage chamber shell, a gas conversion chamber, a powerful permanent magnet push plate, an electromagnetic chamber, a coil, a current controller, a platform, an iron Core and coil spring, the upper part of the tank-type housing is provided with an air outlet, the center of the upper part of the tank-type housing is provided with a platform, the upper surface of the platform is provided with a current controller, the lower surface of the platform The shell of the energy storage chamber is provided, and the shell of the energy storage chamber is divided into a gas conversion chamber and an electromagnetic chamber. The inside of the electromagnetic chamber is provided with an iron core wound with a coil, and the two ends of the copper wire in the coil are connected to the The output ends of the current controller are connected, a through hole is provided at the bottom of the gas conversion chamber, a helical spring is provided in the gas conversion chamber, one end of the helical spring is connected to a push plate of the powerful permanent magnet, and the powerful permanent magnet There is a through hole in the center of the push plate; the air that needs to be injected during work enters the interior of the energy storage chamber shell 2 through the air duct, and at the same time, the current is passed through, so that the electromagnet and the powerful permanent magnet push plate 4 generate repulsive force, pushing the air into the tank shell 1. In addition, the one-way valve can effectively prevent the air from flowing backwards; its disadvantages are: first, the electromagnet pushes the powerful permanent magnet push plate 4 to move downward to compress the gas to do work, and it needs to overcome the elastic force of the coil spring, which consumes the energy of overcoming the coil spring. The second is that the distance between the electromagnet and the powerful permanent magnet push plate 4 is longer, and the energy of the electromagnet cannot be effectively used for doing work; the third is that the power of a single electromagnet is limited and cannot be used for high-power air compression machine, in order to make a high-power air compressor, the electromagnet must be made larger, and then the volume is larger, which is not easy to carry and use; the fourth is because the powerful permanent magnet push plate 4 does work when it moves in one direction, and the compression of the gas low efficiency
