The utility model provides a power
assembly, a dust collection device, a
base station and a cleaning
system, the power
assembly comprises a shell structure, a fan module and a
noise reduction structure, the fan module is arranged in the shell structure, the shell structure and the fan module are matched to form an air duct, and the air duct is used for being communicated with a dust collection
assembly of the
base station; and the
noise reduction structure is arranged outside the air duct. According to the power assembly, the dust collection device, the
base station and the cleaning
system, due to the fact that the
noise reduction structure is arranged outside the
air channel, the
noise reduction structure cannot block the
air channel, low flow resistance
noise reduction can be achieved, the working power needed by the fan module is effectively reduced, and the reduction of the working power of the fan module also correspondingly reduces source noise, so that the service life of the fan module is prolonged. The overall
noise reduction effect is effectively improved, and the user experience is improved.
