The working principle is as follows:

when the user inputs a correct fingerprint in the present invention, the first motor 305 is started to drive the first motor shaft 306 to rotate, so as to drive the first spur gear 308 to rotate, and further drive the second spur gear 309 to rotate, the second spur gear 309 drives the first rotating shaft 311 to rotate, and further drive the first bevel gear 312 to rotate, so as to drive the second bevel gear 314 engaged therewith to rotate, and further drive the second rotating shaft 315 to rotate, and further drive the third bevel gear 316 to rotate, so as to drive the fourth bevel gear 317 engaged therewith to rotate, and further drive the third rotating shaft 318 to rotate, and further drive the third spur gear 319 on the third rotating shaft 318 to rotate, and further drive the rack 321 engaged therewith to move to a side far from the third working chamber 313, so as to drive the first rotating plate 322 to rotate around the fourth rotating shaft 323, and further drive the second slider 324 on one end of the first rotating plate 322 far from the rack 321 to move to a side near to the sixth working chamber 332, finally, the first fixing lock 326 is driven to be disengaged from the first lock slot 327; meanwhile, the second motor 404 is started to drive the second motor shaft 405 to rotate, so as to drive the seventh bevel gear 406 to rotate, so as to drive the ninth bevel gear 409 engaged with the seventh bevel gear to rotate, so as to drive the seventh rotating shaft 410 to rotate, so as to drive the fifth spur gear 411 to rotate, so as to drive the moving plate 412 matched with the seventh spur gear to move upwards, so as to drive the sixth spur gear 413 matched with the seventh spur gear to rotate, so as to drive the spiral rod 417 to rotate, because the right end of the spiral rod 417 is in threaded fit with the eighth working chamber 415, the spiral rod 417 can move towards one side far away from the eighth working chamber 415 while rotating, so as to drive the fifth sliding block 418 to move leftwards, so as to drive the sealing block 420 to move leftwards, release the high pressure in the door body 1, and achieve the pressure balance between the inside and the outside.

When a user inputs multiple wrong fingerprints, the intelligent terminal controls the first air cylinder 303 to start to push the first sliding block 304 to move, so that the second spur gear 309 and the fourth spur gear 328 are meshed with each other, and simultaneously controls the second air cylinder 402 to start, so that the eighth bevel gear 407 and the tenth bevel gear 422 are meshed with each other, and the second motor 404 is started to drive the second motor shaft 405 to rotate, so that the eighth bevel gear 407 is driven to rotate, so that the tenth bevel gear 422 meshed with the eighth bevel gear is driven to rotate, so that the traction rope 429 is pulled to drive the second rotating plate 427 to rotate around the eleventh rotating shaft 428, so that the second fixed lock 431 is driven to enter the second locking groove 432, and secondary locking of the door body 1 is completed;

when a correct fingerprint is input, the intelligent terminal controls the first motor 305 to rotate to drive the first motor shaft 306 to rotate, so as to drive the first straight gear 308 to rotate, so as to drive the fourth straight gear 328 engaged with the first straight gear to rotate, so as to drive the fifth rotating shaft 330 to rotate, so as to drive the fifth bevel gear 331 to rotate, and drive the sixth bevel gear 333 engaged with the fifth bevel gear to rotate, so as to drive the sixth rotating shaft 334 to rotate, because the third sliding block 335 is matched with the sixth rotating shaft 334, when the sixth rotating shaft 334 rotates, the third sliding block 335 will move towards the sixth rotating shaft 334, so as to drive the first rotating plate 322 to rotate through the first expansion spring 336, so that the first fixing lock 326 is separated from the first lock groove 327, and a primary door opening action is completed; at this time, the user needs to input the digital password again, control the second motor 404 to rotate reversely, so as to unlock the second fixed lock 431, start the second cylinder 402 to enable the seventh bevel gear 406 to continue to be meshed with the ninth bevel gear 409, start the second motor 404 at the same time, repeat the above operations to release the air pressure inside the door body 1, balance the air pressure inside and outside the door body 1, and finally realize the purpose of unlocking and opening the door.

According to the invention, through the arrangement of the primary door opener 3 and the secondary door opener 4, when a user inputs a fingerprint error for multiple times, the secondary door opener 4 is started to lock the door body 1 for the second time, and at the moment, a digital password is input on the basis of inputting a correct fingerprint, so that the first fixed lock 326 and the second fixed lock 431 can be opened simultaneously, and thus, the safety of the door body is improved, and the safety of the user is guaranteed;
