firstly, a normal door closing state: the door body 200 and the inner container 100 are kept in a stable door closing state by the attraction of the magnet. The drive mechanism 300 is now in an initial state, as shown in fig. 6.

II, automatic door opening stage: the wax motor 310 is energized to rotate the lever 330 counterclockwise about the fixed shaft 353, thereby moving the driving lever 320 forward. The ejection force generated in the process can overcome the magnetic attraction between the door body 200 and the inner container 100, the pulling force provided by the anti-falling mechanism 400 and the gravity of the door body 200 are prevented, and finally the distance between the door body 200 and the inner container 100 is changed from T1 to T2, so that the door opening action is realized. As long as T2 is greater than T1, automatic door opening is realized, as shown in figures 2 and 4.

And thirdly, automatically closing the door: the wax motor 310 is powered off, the mandril of the wax motor 310 retracts to return to the initial state, and the driving rod 320 retracts under the action of the return spring 340 to drive the lever 330 to return clockwise. As shown in fig. 1, 6 and 7, when the door 200 loses its ejection force, the door 200 rotates in the direction of the inner container 100 due to the self-lifting force and the pulling force of the door pulling rope 431, and finally, a stable door closing state is achieved by the attraction force of the magnet.

Fourth, the wax motor 310 cannot be maintained in an energized state for a long time due to its inherent characteristics. In order to realize the automatic door opening and closing function within a certain time, the automatic door opening and closing function can be realized by repeating the automatic door opening stage and the automatic door closing stage.
