The lock motor 9-2, the lock dead signal switch 9-8 and the unlock signal switch 9-10 are respectively connected with the main control unit 8 in the door.

The process of automatic door operator assembly in this embodiment is: (1) a motor 1-2 is arranged on the shell 1-3, and then an output shaft of the motor is inserted into the speed reducer 1-1 and the speed reducer is fixed; (2) a rotating arm 3 is arranged on the output shaft of the speed reducer; (3) the power source 1 of the door opener assembled above is arranged on the upright post 2 of the door frame and the door in the toilet; (4) the other end of the rotating arm 4 is provided with a pin shaft and a connecting rod 4; (5) a connecting rod support 5 is arranged on the door body 6, and is connected with the connecting rod 4 by a pin shaft; (6) an electric lock 9 is arranged on the door body 6 and the upright post 7 of the electric lock side door frame; (7) the inside and outside of the door frame upright post 7 are respectively provided with an inside door main control unit 8 and an outside door sensing and displaying unit 11; (8) and finally, electrifying and debugging the connecting wire.

The working process of the automatic door opener for the vertical hinged door in the toilet of the embodiment is as follows:

and assembling the assembled speed reducer 1-1 and the motor 1-2 on the shell 1-3 by screws to form a unit assembly. The unit assembly is arranged on the door frame upright post 2, and the motor 1-2 is started under the control of the main control unit 8 in the door. The motor 1-2 drives the output shaft of the speed reducer 1-1 to rotate, and then drives the rotating arm 3 arranged on the output shaft of the speed reducer 1-1 to rotate, namely, the connecting rod 4 and the connecting rod support 5 are pulled or pushed to move, and the door body 6 is connected to the door frame 2 through the hinge 10, so that the door opening and closing processes of the door 6 are realized.

The working process of the electric lock 9 is as follows: the door locking signal is sent by the door inner main control unit 8, the locking motor 9-2 rotates in the forward direction to drive the small bevel gear 9-3 on the motor output shaft and the large bevel gear 9-4 meshed with the small bevel gear to rotate, and then the shifting rod 9-6 connected to the large bevel gear shaft 9-5 shifts the lock catch 9-7 to do linear motion inserted into the lock catch box 9-9, so that the door locking is realized.

The main control unit 8 in the door sends out a door opening signal, the lock motor 9-2 rotates reversely to drive the small bevel gear 9-3 on the motor output shaft and the large bevel gear 9-4 meshed with the small bevel gear to rotate, and then the deflector rod 9-6 connected to the large bevel gear shaft 9-5 drives the lock catch 9-7 to do linear motion away from the lock catch box 9-9, so that the door opening is realized.

An unlocking signal switch 9-10 and a locking signal switch 9-8 are also arranged on the electric lock 9, and a state signal of the electric lock 9 is fed back to the main control unit 8 in the door. When the lock catch 9-7 is completely opened, the unlocking signal switch 9-10 is triggered to inform the main control unit 8 in the door that the lock is unlocked, and when the lock catch 9-7 is completely locked, the locking signal switch 9-8 is triggered to inform the main control unit 8 in the door that the electric lock is completely locked.

The door external sensing and displaying unit 11 in this embodiment can control the door to be opened or closed by non-contact sensing, and display whether the toilet room can be used. After the user's hand is put in the induction zone of the outer induction of door and display element 11, outer induction of door and display element 11 send signal give interior main control unit 8, specifically as follows:

when no person is in the toilet, a green 'no person' indicator lamp on the outside door sensing and displaying unit 11 is lightened to indicate that the toilet can be used, and a user can automatically open the door within a range of 50-100mm away from the front of the unit panel through gesture sensing;

after someone got into the lavatory, the green "not locking" pilot lamp on the main control unit 8 was bright in the door, and the response lamp scintillation of closing the door simultaneously, the demonstration needs to feel to close the door, and after sensing the staff action, the electric lock locked the door, red "locked" pilot lamp was lighted on the panel, and green "not locking" pilot lamp goes out, also will feel to open the door green light simultaneously and light. The red in-use indicator lamp on the panel of the outdoor sensing and display unit 11 is turned on, and the green unmanned indicator lamp is turned off.

When the door is used and needs to be taken out, the human hand inducts to open the door within the range of 50-100mm right ahead of the green door opening inducting switch on the main control unit 8 in the door, the electric lock is unlocked and automatically opens the door, and meanwhile, the panel door opening inducting green light is turned off and the red door closing inducting indicating light is turned on again. The "in use" indicator lights on the panel of the outdoor sensing and display unit 11 are turned off, and the "no man" indicator lights are turned on again. The door is automatically closed again (unlocked) after the door is opened for 20 seconds.

The in-door main control unit 8 can set motor parameters, door opening speed, door closing speed, door opening angle, dwell time, torque force adjustment and alarm (time can be set) for overlong service time.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
