A display screen 1218 is provided on the cover body 121 to display the weight detected by the weight sensor 1126. The cover body 121 is provided with a display screen 1218 to display the weight detected by the weight sensor 1126. The weight sensor 1126 is electrically connected to the control module 128 so that the detection threshold of the weight sensor 1126 can be set through the control module 128. When the weight of the garbage in the inner barrel 111 exceeds the threshold, the display screen 1218 displays an overweight alarm to remind the user that the garbage in the inner barrel 111 needs to be dumped into a recycling area.

[0073] In an embodiment of the present invention, laser sensors 1112 are provided on the opposite side walls of the inner barrel 111, and the laser sensors 1112 are located on the handle 1111, so as to detect the capacity of the garbage in the inner barrel 111 through the laser sensors 1112. When there is too much garbage in the inner barrel 111 and it blocks the signal transmission between the two laser sensors 1112, it indicates that the capacity of the garbage in the inner barrel 111 has reached the upper limit, and the display screen 1218 displays an overcapacity alarm to remind the user to pour the garbage in the inner barrel 111 into the recycling area.

[0074] In an embodiment of the present invention, the laser sensor 1112 on one side of the inner barrel 111 is a laser transmitter, and the other side is a laser receiver. The laser transmitter transmits a signal to the laser receiver. When the garbage capacity in the inner barrel 111 has not reached the upper limit, the laser receiver can normally receive the signal emitted by the laser transmitter; when the garbage capacity in the inner barrel 111 reaches the upper limit, the signal emitted by the laser transmitter is blocked by the garbage, so that the laser receiver cannot receive the signal emitted by the laser transmitter. Finally, the display screen 1218 shows that the capacity of the inner barrel 111 has reached the upper limit, reminding the user to dump the garbage in the inner barrel 111 into the recycling area.
