With the counterclockwise rotation of the straight shaft 200, the cam 2001 connected to the other end thereof rotates counterclockwise, and at this time, the cam 2001 extrudes the air pressing plate 25 periodically upwards, and then the air pressing plate 25 moves up and down repeatedly under the periodic upward extrusion of the cam 2001 and the compression force of the spring rod 23, so that the cold air in the cold storage bin 21 is compressed, and finally the compressed cold air enters the first heat dissipation hole 16, the air pipe 19 and the third heat dissipation hole 18, thereby playing a role of compressing the cold air entering the cold storage bin 21 and entering the three heat dissipation holes respectively, and also playing a role of preparing for subsequent heat dissipation.

[0047] In use, first, the stator assembly 13 is composed of a core and a winding, when the magnetic field of the rotor assembly 12 rotates, the stator winding is cut, causing the magnetic flux in the stator winding to change.
