CLEANING SYSTEM

WIPO Patent Application WO/2024/061293

A1

A cleaning system. In the cleaning system, the relative position of a dust collection box (24) and of a recycling box (31) are set, such that a recycling fan (32) can provide, without the need for using a recycling air duct (4) or merely by means of a relatively short recycling air duct (4), a recycling airflow for recycling and clearing filth in the dust collection box (24). In this way, it is unnecessary to provide a bent air duct between the recycling box (31) and the dust collection box (24); furthermore, the loss of power of the recycling fan (32) is avoided while the recycling fan (32) provides recycling power. A recycling fan (32) having high power can be replaced with a recycling fan (32) having power lower than 550 W, such that the cleaning efficiency of the cleaning system can be ensured, the operation noise of a base station (1) during filth recycling and clearing can also be effectively reduced, and the noise of the cleaning system during operation can thus be reduced to 80 dB or less. Moreover, a base (12) is obliquely arranged in the base station (1), such that the area occupied by the cleaning system in a horizontal direction can be effectively reduced, thereby facilitating the miniaturization design of the cleaning system.
