An operation screen 3 is provided on the front end surface of the front panel 1. A delivery port 4 is provided on the front end surface of the front panel 1. A delivery door 5 is slidably connected to the inner wall of the delivery port 4. A group of fixed blocks 51 are provided on the rear end surface of the delivery door 5. The delivery door 5 is movably connected to an anti-pinching strip 6 through the fixed blocks 51. A plurality of anti-pinching sensors 8 are movably installed on the rear end surface of the delivery door 5. An electric push rod 9 is movably installed between the rear end surface of the delivery door 5 and the top panel 2.

[0019] In this embodiment, a delivery port 4 is provided on the front plate 1 and a delivery door 5 is installed, an electric push rod 9 is installed between the delivery door 5 and the top plate 2, and the rear end of the delivery door 5 is slidably connected to the movable groove 61 through a fixed block 51 to install an anti-pinch strip 6, and an anti-pinch sensor 8 is installed above the anti-pinch strip 6, so that after the garbage is delivered, the electric push rod 9 drives the delivery door 5 and the anti-pinch strip 6 to move downward, and the anti-pinch strip 6 moves downward to touch the hand or garbage. The height of the hand or the garbage prompts the movable groove 61 to move upward to slide the fixed block 51, and the anti-pinch strip 6 touches the anti-pinch sensor 8. The anti-pinch sensor 8 sends a signal to stop the delivery door 5 from moving, and the electric push rod 9 drives the delivery door 5 and the anti-pinch strip 6 to move upward, so that the anti-pinch strip 6 touches the anti-pinch sensor 8 to send a signal to prevent the hand from being pinched; even when the anti-pinch sensor 8 fails, the contact between the anti-pinch strip 6 and the hand or garbage can enable the person to quickly retract his hand, thereby preventing the delivery door 5 from pinching his hand.

[0020] See also Figure 2-3 In order to achieve the function of preventing the hand from being pinched by triggering the switch signal through the anti-pinch strip 6, in this embodiment, the delivery door 5, the fixed block 51, the spring 52, the anti-pinch strip 6, the movable groove 61, the silicone strip 7, the anti-pinch sensor 8, and the electric push rod 9;

[0021] The anti-pinch sensor 8 can be set to two or more, and the anti-pinch sensor 8 is set above the top of the anti-pinch strip 6. A group of movable grooves 61 are opened in the vertical part of the anti-pinch strip 6. The fixed block 51 is slidably connected to the inner wall of the movable groove 61, and a spring 52 is arranged between the fixed block 51 and the bottom of the inner wall of the movable groove 61. The bottom horizontal plane of the anti-pinch strip 6 is lower than the bottom horizontal plane of the delivery door 5.

[0022] In this embodiment, two or more anti-pinch sensors 8 are provided, and are arranged above the anti-pinch strip 6. A movable groove 61 is provided in cooperation with the anti-pinch strip 6 to slide and connect with the fixed block 51, and a spring 52 is provided between the fixed block 51. The bottom horizontal plane of the anti-pinch strip 6 is lower than the delivery door 5, so that the delivery door 5 drives the anti-pinch strip 6 to move downward. When the anti-pinch strip 6 touches the hand or garbage, the height of the hand or garbage will prompt the movable groove 61 to move upward to slide the fixed block 51 and compress the spring 52. The anti-pinch strip 6 moves upward to touch the anti-pinch sensor 8. The anti-pinch sensor 8 sends a signal to the main board to prompt the electric push rod 9 to drive the delivery door 5 to stop moving downward and move upward, thereby preventing the hand from being pinched.

[0023] It should be noted that a silicone strip 7 is movably installed on the horizontal surface at the bottom of the delivery door 5 and the horizontal surface at the bottom of the anti-pinch strip 6. In this embodiment, by arranging the delivery door 5 and the bottom of the anti-pinch strip 6 to assemble the silicone strip 7, the hands can be prevented from being scratched when the anti-pinch strip 6 touches the hands or garbage; with the bottom of the anti-pinch strip 6 being lower than the delivery door 5, when the anti-pinch sensor 8 fails and cannot detect or send a signal, the contact of the anti-pinch strip 6 can prompt the personnel to quickly leave the delivery port 4 to prevent the delivery door 5 from pinching the hands; at the same time, the setting of the spring 52 can prevent the anti-pinch strip 6 from detaching from the delivery door 5 when sliding the fixed block 51 up and down.

[0024] The working principle of the above embodiment is:

[0025] A delivery port 4 is provided on the front plate 1 and a delivery door 5 is installed. An electric push rod 9 is installed between the delivery door 5 and the top plate 2. The rear end of the delivery door 5 is slidably connected to the movable groove 61 through a fixed block 51 to install an anti-pinch strip 6. An anti-pinch sensor 8 is installed above the anti-pinch strip 6. When a person scans the operation screen 3, the electric push rod 9 drives the delivery door 5 to drive the anti-pinch strip 6 to move up to open the delivery port 4. The person starts to put in the garbage. After the putting in is completed, the electric push rod 9 drives the delivery door 5 and the anti-pinch strip 6 to move down. If the person reaches out to put in the garbage again, the anti-pinch strip 6 will move down. When the hand or garbage is moved and touched, the height of the hand or garbage causes the movable groove 61 to move up the sliding fixed block 51, and the anti-pinch strip 6 touches the anti-pinch sensor 8. The anti-pinch sensor 8 sends a signal to stop the delivery door 5 from moving, and the electric push rod 9 drives the delivery door 5 and the anti-pinch strip 6 to move up, thereby preventing the hand from being pinched by the anti-pinch strip 6 touching the anti-pinch sensor 8 to send a signal; even when the anti-pinch sensor 8 fails, the contact between the anti-pinch strip 6 and the hand or garbage can enable the person to quickly retract his hand, thereby preventing the delivery door 5 from pinching his hand.
