     The bin lid  2  can be integrated with a complete processing actions of garbage bags, such as storing a garbage bag  3 , expanding the garbage bag  3 , packing the garbage bag  3 , and cutting the garbage bag  3 , which are basically automated. 
     As shown in  FIGS. 3 and 4 , the bin lid  2  comprises a main body  21  and a lid body  22  rotatably arranged on an upper side of the main body  21 , wherein the main body  21  is provided with a rotary packing mechanism  23  and an automatic cutting mechanism  24 . The lid body  22  is provided with a blowing-expanding mechanism  25  used for blowing air to the garbage bag  3  opened on an annular storage box  231  of the rotary packing mechanism  23  after the lid body  22  is rotated to the main body  21 . 
     The garbage bag  3  has a long cylindrical shape as a whole after being expanded, and circumference of the garbage bag  3  is placed along the storage box  231  after being axially shrank, and a bottom of a seal of the garbage bag  3  is located at the middle of the storage box  231 . The garbage bag  3  can be cut into several bag bodies to realize continuous packing, placement and expansion of the garbage bag  3 . A throw opening is formed at the middle of the storage box  231  for throwing the garbage into the garbage bag  3 . 
     The annular storage box  231  is used for storing the garbage bags  3  and allows the garbage bags  3  to expand downwards, the blowing-expanding mechanism  25  makes the garbage bags  3  within the storage box  231  to be expanded to the bin body  1 , the garbage bag  3  with stored garbage is rotated and packed by the rotary packing mechanism  23 , and the seal of the packed garbage bag  3  is cut by the automatic cutting mechanism  24 . 
     As shown in  FIGS. 3 to 5 , the blowing-expanding mechanism  25  for garbage bag is generally arranged above the storage box  231  and comprises an air blowing member  251  for blowing air to the garbage bag  3  that is open on an upper end of the bin body  1  of the garbage bin, so as to make the garbage bag  3  expand downwards onto inner wall of the bin body  1  of the garbage bin. 
     The air blowing member  251  is located above an upper side of the storage box  231 , and a blowing direction of the air blowing member  251  is corresponding to an inner circle of the storage box  231 . Once the blowing-expanding mechanism  25  for garbage bag blows air downwards, a bottom of the garbage bag  3  is expanded onto inner wall of the bin body  1 , and the inner ring of the storage box  231  at the upper end can be used as a throwing port for throwing the garbage into the garbage bin. 
     The garbage bag is expanded in the manner of the blowing-expanding mechanism blowing air, which expanding method is smart and quick. The new garbage bag has not been placed and touched with garbage, which is clean and hygienic, and there will be no peculiar smells flowing during the blowing process, which can reduce the peculiar smells in the environment. 
     An air outlet  2511  of the air blowing member  251  has a long strip shape, which can increase a blowing radiation range of the garbage bag  3 . 
     The blowing-expanding mechanism  25  further comprises a blast chamber  252 , the air blowing member  251  is arranged within the blast chamber  252 , and the blast chamber  252  is provided with air inlets  2524  for air entering and air blowing ports  2521  for blowing out the air sent by the air blowing member  251 .

     When the bin lid  2  is closed, the blowing-expanding mechanism  25  blows air into the storage box  231  to expand the garbage bag  3  downwards to fit with inner walls of the bin body  1  of the garbage bin. The lid body  22  can be turned over and opened to dump garbage into the garbage bag  3 . 
     As shown in  FIGS. 6 to 9 , when the garbage bag  3  is full and needs to be packed and taken out, the rotary packing mechanism  23  can be started up. The rotary packing mechanism  23  comprises a rotary driving device  232  for driving the storage box  231  to rotate. The rotary driving device  232  interacts with the storage box  231  to make the storage box  231  and the garbage bags  3  within the storage box  231  rotate relative to the garbage bag  3  with stored garbage. The rotation of the storage box  231  make the garbage bag  3  that is expanded downwards and with stored garbage rotate, whose upper end then is twisted and sealed. 
     The rotary driving device drives the storage box to rotate to twist and seal, so the seal is tighter, the garbage inside is not easy to leak, and the seal is small, which is conducive for subsequent automatic cuttings. 
     The rotary driving device  232  comprises a rotatable drive member  2321  for driving the storage box  231  to rotate when the drive member  2321  rotates. Furthermore, the drive member  2321  is an annular drive disk which is configured as rotatable and circumferentially positioned on the storage box  231 . When the drive disk rotates, the storage box  231  is driven to rotate, thus to twist relative to the underneath garbage bag  3  with stored garbage. 
     Furthermore, the drive disk and the storage box  231  are arranged concentrically, the drive disk is engaged with the storage box  231 , so that the storage box  231  is driven to rotate when the drive disk rotates. 
     In some embodiments, the drive disk comprises an annular gear ring  2322 , teeth are arranged on an outer ring of the gear ring  2322 , and the storage box  231  is located on an inner ring of the gear ring  2322 .

     In this embodiment, the positioning portion  2323  is ring-shaped and arranged along an inner circumference of the gear ring  2322 , the storage box  231  is placed on the positioning portion  2323 , and the engagement portion  2324  is a boss protruding upwards on a side for positioning, and grooves  2311  are provided at the bottom of the storage box  231  for inserting the boss. 
     A plurality of engagement portions  2324  are provided along the circumference of the positioning portion  2323  for engaging with each of the grooves  2311  at the bottom of the storage box  231  to rotate synchronously. In other embodiments, an engagement position of the drive disk and the storage box  231  can also be located on an inner wall of the gear ring  2322  and an outer wall of the storage box  231 , or teeth or other structures are directly arranged on the circumference of the storage box  231 , so that the rotary driving device  232  drives the storage box  231  to rotate directly. 
     Generally, the rotary driving device  232  further comprises a rotary motor  2325  for driving the drive member  2321  to rotate, and a gear set for transmitting outputs of the rotary motor  2325 . 
     After the garbage bag  3  with stored garbage is twisted and sealed, it needs to be cut apart from the garbage bag  3  within the storage box  231  for next garbage storage.

After the garbage bag  3  is twisted and sealed, the sealed position is just corresponding to the position of the cutting member  2432 . After the first cutting assembly  243  and the second cutting assembly  244  are approached, the cutting member  2432  abuts on the twisted seal and then cuts it apart. 
     Furthermore, the cutting member  2432  is a hot melt head electrically connected to a power supply, once the seal is clamped, the hot melt head is energized to heat up, so as to fuse and cut the sealed position. 
     The automatic cutting mechanism  24  further comprises a position switch  246  for setting the position of the first cutting assembly  243  and the second cutting assembly  244  when they are approached, thus the first cutting assembly  243  and the second cutting assembly  244  stop moving after approaching to each other and clamping the seal, and then the cutting member  2432  is electrically connected to the power supply for generating heat to fuse the twisted seal. 
     The cutting drive device  245  comprises a first drive assembly  2451  and a second drive assembly  2452  for driving the first cutting assembly  243  and the second cutting assembly  244  to move back and forth, respectively.
