An entrance door with good airtightness, the working principle is as follows:

In daily use, the first sealing block 309 and the second sealing block 312 are placed inside the groove, and a portion of them is left inside the connecting groove;

When opening or closing the door, the palm is held on the handle 4 to trigger the touch-sensitive switch 5 on the handle 4, so that the electromagnet 301 is energized, and the electromagnet 301 generates magnetic force, which pushes the strong magnetic block 302 to move. The strong magnetic block 302 drives the connecting block 303 to move under the limit of the limit block 314, and simultaneously squeezes the reset spring 315. Under the cooperation of the teeth 304 and the first gear 305, the movement of the connecting block 303 drives the first gear 305 to rotate, and the first gear 305 drives the screw rod 306 to rotate, and the screw rod 306 drives the slider 307 to move, and the slider 307 drives the second rack 308 to move under the limit of the first fixed block 316 and the guide groove, and the second rack 308 drives the first sealing block 309 to move, so that the first sealing block 309 is separated from the groove;

The second rack 308 moves while driving the second gear 310 to rotate. The second gear 310 drives the third rack 311 to move under the limitation of the second fixing block 317 and the guide groove. The third rack 311 drives the second sealing block 312 to move, so that the second sealing block 312 is separated from the groove.

When the palm leaves the touch sensing switch 5, the electromagnet 301 is powered off, the reset spring 315 is no longer under force, and the connecting block 303 is pushed back to move, so that the first gear 305 rotates. At this time, the rotation direction of the first gear 305 is opposite to the rotation direction of the electromagnet 301 when it is powered on, and the first gear 305 performs the opposite movement of the above movement, so that the first sealing block 309 and the second sealing block 312 are placed inside the groove to seal the upper and lower gaps between the door frame 2 and the door body 1.
