[0028] The pneumatic cleaning device 6 is hung on the bottom surface of the premix tank top cover 1 through the U-shaped hanger 9. The pneumatic cleaning device 6 comprises a first air blower 61, a second air blower 62, a first annular air pipe 63 and a second annular air pipe 64. The first air blower 61 and the second air blower 62 are both connected to the first annular air pipe 63 through pipelines, so as to provide sufficient airflow and ensure the cleaning effect.
