The invention relates to the technical field of smart home, and discloses a device capable of achieving
silence automatic door closing based on the non-
Newtonian fluid principle. A door frame and a shell are included. A
fluid pipe is fixedly connected in the door frame and internally movably connected with a magnetic pole. Non-
Newtonian fluid is arranged in the
fluid pipe. A motor is fixedly connected in the shell. The top of the motor is fixedly connected with a
bevel gear. A long rod is fixedly connected in the shell. Under the interaction of a second gear, a supporting rod, a rotation rod,a first contact point, a first spring, an
electromagnet, a clamp groove, a second spring, a second contact point, a
magnet, a buckle and a pull ring, a stirring rod at the outer portion of the secondgear can jack the end, in the shell, of the rotation rod, the first contact point makes contact with the second contact point under the action of the rotation rod, the
electromagnet is powered on, themagnet can be attracted, under magnetic force attraction of the buckle and the clamp groove, a door can be completely closed, and accordingly the effect of automatic door closing can be achieved.
