And when the magnetic pole switching button is pressed down, the first permanent magnet rotates 180 degrees around the central axis of the first permanent magnet, and the magnetic pole on the opposite side of the first permanent magnet and the second permanent magnet is changed.
The control method comprises the following steps: when the machine door 9 and the inner barrel door 10 are both closed, the ferromagnetism of the first permanent magnet and the ferromagnetism of the second permanent magnet are the same, when a user needs to open the machine door 9, the magnetic pole switching button is pressed down, the magnetic pole switching button is in a pressing-in state at the moment, the first permanent magnet rotates for 180 degrees, the ferromagnetism of the first permanent magnet and the ferromagnetism of the second permanent magnet are opposite and mutually attracted, the attraction force is greater than the locking force of the inner barrel door 10 lock, and the machine door 9 is linked with the inner barrel door 10 to be opened. When a user needs to close the machine door 9, the magnetic pole switching button is pressed again, the magnetic pole switching button is reset, the first permanent magnet rotates 180 degrees again towards the opposite direction, the first permanent magnet and the second permanent magnet are same in ferromagnetism and repel each other, the repulsion force is larger than the unlocking force of the inner cylinder door 10 lock, and the machine door 9 is linked with the inner cylinder door 10 to close.
Alternatively, the controller 13 controls the first permanent magnet to rotate around the central axis thereof so as to switch the magnetic poles of the first permanent magnet and the second permanent magnet at the opposite sides. The control method comprises the following steps: judging whether the machine door 9 is opened or not, if so, controlling the second permanent magnet to rotate by the controller 13 to enable the second permanent magnet to be opposite to the magnetic pole on the opposite side of the second permanent magnet, enabling the first permanent magnet and the second permanent magnet to attract each other, enabling the attraction force to be larger than the locking force of the inner cylinder door 10 lock, and enabling the machine door 9 to link the inner cylinder door 10 to open; if the judgment result is negative, the ferromagnetism of the first permanent magnet and the second permanent magnet is kept in the same state, the first permanent magnet and the second permanent magnet repel each other, and the repulsion force of the first permanent magnet and the second permanent magnet is larger than the unlocking force of the inner cylinder door 10 lock, so that the machine door 9 is linked with the inner cylinder door 10 to close.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
