The specific use process of the embodiment is as follows:
As shown in fig. 7, the flip cover 3 and the air guide pressing plate 32 are opened, and then the bag body drawing part in the container 35 of the garbage bag without break point is knotted and put into the annular platform formed by the concave inner edge of the upper shell 33.
As shown in fig. 8, the air guide platen 32 is turned and closed. When the garbage bag is not filled in the inner container 2, the infrared emitting element 28 emits infrared rays which are received by the infrared receiving element 29. The fan 6 works to pump the air below the garbage bag and discharge the air above the garbage bag. Before the blower 6 is operated, the baling rod 9 is moved inward from the end of the guide rail 12 by a distance by a motor 10 and a timing belt 11. After the packing rod 9 has moved the distance, the second protrusion 19 is disengaged from the first protrusion 18, and the latch 15 is deflected inward by the elastic member 17. At this time, the upper end (bent end) of the latch 15 passes through the housing and is latched with the latch portion 16 of the flip 3, so as to latch the flip 3 to the middle seat (see fig. 13 and 14 in detail).
As shown in fig. 9 and 10, the gas from the gas outlet 36 creates a positive pressure above the garbage bag and fills the inner container 2, completing the bagging (bag changing).

The packing rod 9 is returned to the position and moved to the end of the guide rail 12, the second protrusion 19 of the packing rod is abutted against the first protrusion 18, and then the latch 15 compresses the elastic piece 17 and makes the latch 15 deflect outwards, so that the upper end of the latch 15 is separated from the buckling part 16, and the flip 3 is normally opened and closed without being obstructed by the latch 15.
As shown in fig. 11 and 12, when the garbage bag is full of garbage and needs to be packed, the two folding rods 8 are controlled to move in opposite directions with the motor 10 and the timing belt 11 on the guide rail 12, and when the two folding rods 8 reach a predetermined position, they are detected by the limit switch 14. At this point, the baling rod 9 is again moved towards the fuse element 5 until it comes into contact with it and fuses and seals the disposal bag (see figures 4, 5 and 6 for details). Finally, the folding rod 8 and the packing rod 9 are reset, the side plate 26 is opened from the side door 21, and the garbage bag is taken away.
