[0007] Furthermore, the driving mechanism includes two mounting plates fixedly connected to the top of the inner side of the box body, a rotating shaft is rotatably arranged between the two mounting plates, a driving motor for driving the rotating shaft to rotate is installed on one of the mounting plates, a connecting block is fixedly sleeved on the rotating shaft, and the bottom of the connecting block is fixedly connected to the top of the main box cover.

[0008] Furthermore, rubber pads are provided on the outer side walls of the main box cover and the bottom box cover.

[0009] Furthermore, a box cover switch button is provided on the front side of the box body, and the box cover switch button is electrically connected to the controller.

[0010] Furthermore, an infrared transmitter and an infrared receiver are respectively embedded on both sides of the delivery port, and the infrared transmitter and the infrared receiver are correspondingly arranged.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] When a person approaches the delivery port, the infrared sensor senses that someone is approaching, and the controller controls the driving mechanism to start, driving the main cover to rotate, and the main cover drives the bottom cover to move away from the delivery port. After the garbage is delivered and the person is away from the delivery port, the driving mechanism drives the main cover to reset, and the main cover drives the bottom cover to cover the delivery port to prevent the smell of garbage in the storage chamber from affecting the surrounding air. When the infrared sensor fails, the driving mechanism drives the main cover to reset. If the person's hand is still on the bottom of the delivery port, the person's hand will contact the bottom cover, and the bottom box cover will rotate around the rotating rod in the direction away from the delivery port, thereby avoiding pinching the hand. The utility model avoids pinching the hand when the electronic device fails by arranging a mechanical anti-pinch structure. BRIEF DESCRIPTION OF THE DRAWINGS
