[0050] In an embodiment, referring to Figure 1 , the fan 3 makes the garbage can 1 in a negative pressure state in a working state.

[0051] Specifically, the back-blowing mechanism comprises an exhaust duct 4, a water mist spraying device 5 and a suction cup 8, one end of the exhaust duct 4 is connected with the fan 3 of the suction-sweeping sweeper, the other end of the exhaust duct 4 is arranged near the inlet of the suction cup 8, the water mist spraying device 5 is arranged at the other end of the exhaust duct 4, the suction cup 8 is connected with the garbage can 1, the fan 3 makes the garbage can 1 in a negative pressure state in a working state.

[0054] The sensor comprises a negative pressure sensor.

[0055] Specifically, the back-blowing mechanism comprises: an exhaust duct 4, a water mist spraying device 5 and a suction cup 8, one end of the exhaust duct 4 is connected with the fan 3 of the suction sweeping vehicle, the other end of the exhaust duct 4 is arranged near the inlet of the suction cup 8, the water mist spraying device 5 is arranged at the other end of the exhaust duct 4, the suction cup 8 is connected with the garbage can 1, the back-blowing mechanism further comprises a pressure sensor, the pressure sensor is arranged in the suction cup 8 and the garbage duct 7; there is a detection position of the negative pressure sensor in the suction cup 8, so that the specific size of the negative pressure in the suction cup 8 can be obtained in real time; meanwhile, there is also a detection position of the negative pressure sensor in the garbage duct 7, so that the specific size of the negative pressure in the garbage duct 7 can be obtained in real time, and the blockage of the garbage outside the suction cup door 81 can be judged through differential pressure comparison. When the garbage is too much to block the suction cup door 81, the actual opening of the suction cup door 81 becomes smaller.
