After the coil core 301 is energized, under the action of the electric and magnetic fields, the rotating blade 201 rotates, driving the eccentric main shaft 104 and the intake-side eccentric shaft 110 to rotate. The blade rotor body 106 is rotatably mounted on the eccentric position of the eccentric main shaft 104 through the bushing 107, which facilitates the rotation of the blade rotor body 106 relative to the eccentric main shaft 104. The gear shaft 108 and the blade rotor body 106 are connected by a flat key 109. The connection is fixed, and the large gear ring 112 is mounted on the compressor housing 11. The gear shaft 108 meshes with the large gear ring 112. Since the vane rotor 106 is mounted at an eccentric position on the eccentric main shaft 104, the eccentric main shaft 104 rotates under the action of the motor. The vane rotor 106, located inside the compressor housing 11, collides with the inner wall of the compressor housing 11 and rotates around the eccentric main shaft 104. Under the action of the gear shaft 108 and the large gear ring 112, the vane rotor 106 and the eccentric main shaft... The rotation direction of 104 is opposite. The outer wall of the blade rotor 106 collides and compresses with the inner wall of the compressor housing 11 to achieve the function of compressing air. An air inlet 4 is opened on the air inlet end cover 111, and an exhaust port 5 is opened on the chamber cylinder 101 to realize the functions of air intake and exhaust of the compressor housing 11. The rotating blade 201 is located at the air inlet 4. By rotating the blade 201, the air intake of the compressor housing 11 is increased. A strip-shaped through hole is opened on the outer wall of the blade rotor 106 to facilitate the air entering through the air inlet 4 to flow into the cavity formed by the outer wall of the blade rotor 106 and the inner wall of the chamber cylinder 101. The air in the cavity is compressed by the rotation of the blade rotor 106. The cycloidal equation of the blade rotor in the compressor housing is shown in the figure. A spring radial seal 102 is provided between the outer wall of the blade rotor 106 and the inner wall of the chamber cylinder 101 to seal the cavity and realize the function of the compressor.

The blade rotor body 106 is rotatably mounted on the eccentric position of the eccentric main shaft 104 through the bushing 107, which facilitates the rotation of the blade rotor body 106 relative to the eccentric main shaft 104. The gear shaft 108 and the blade rotor body 106 are connected by a flat key 109. The connection is fixed, and the large gear ring 112 is mounted on the compressor housing 11. The gear shaft 108 meshes with the large gear ring 112. Since the vane rotor 106 is mounted at an eccentric position on the eccentric main shaft 104, the eccentric main shaft 104 rotates under the action of the motor. The vane rotor 106, located inside the compressor housing 11, collides with the inner wall of the compressor housing 11 and rotates around the eccentric main shaft 104. Under the action of the gear shaft 108 and the large gear ring 112, the vane rotor 106 and the eccentric main shaft... The rotation direction of 104 is opposite. The outer wall of the blade rotor 106 collides and compresses with the inner wall of the compressor housing 11 to achieve the function of compressing air. An air inlet 4 is opened on the air inlet end cover 111, and an exhaust port 5 is opened on the chamber cylinder 101 to realize the functions of air intake and exhaust of the compressor housing 11. The rotating blade 201 is located at the air inlet 4. By rotating the blade 201, the air intake of the compressor housing 11 is increased. A strip-shaped through hole is opened on the outer wall of the blade rotor 106 to facilitate the air entering through the air inlet 4 to flow into the cavity formed by the outer wall of the blade rotor 106 and the inner wall of the chamber cylinder 101. The air in the cavity is compressed by the rotation of the blade rotor 106. The cycloidal equation of the blade rotor in the compressor housing is shown in the figure. A spring radial seal 102 is provided between the outer wall of the blade rotor 106 and the inner wall of the chamber cylinder 101 to seal the cavity and realize the function of the compressor. An exhaust port 5 is provided on the chamber cylinder 101 to discharge exhaust gas.
