The sensor assembly 3 is used to detect the weight or volume of the garbage in the garbage bag; the controller 4 , the closing assembly 2 and the sensor assembly 3 are respectively electrically connected to the controller 4 .

For example, the sensor assembly 3 can be a combination of a weight sensor and a distance sensor, the weight sensor is arranged at the bottom of the barrel 1 , and the weight directly acts on the weight sensor after the garbage is loaded into the garbage bag. When the weight sensor detects that the weight of the garbage in the garbage bag reaches the weight threshold, the controller 4 can directly control the closing assembly 2 to tighten the bag mouth of the garbage bag, or it can be further judged by the distance sensor whether the garbage volume in the garbage bag reaches the threshold. The volume threshold, if the volume threshold is reached, the controller 4 controls the closing assembly 2 to tighten the mouth of the garbage bag. Alternatively, the distance sensor can directly determine the garbage volume in the garbage bag. If the garbage volume in the garbage bag reaches the volume threshold, the controller 4 controls the closing assembly 2 to tighten the garbage bag mouth.

As an optional embodiment, as shown in the cross-sectional schematic diagram A-A shown in FIG. 3 , the inner four side walls of the barrel body 1 are respectively provided with two pushing mechanism accommodating grooves 11 and two pressing mechanism accommodating grooves 12 , The two accommodating grooves 11 for the pushing mechanism are arranged opposite to each other, and the two accommodating grooves 12 for the pressing mechanism are arranged opposite to each other.
