When the cross-sectional area of the end of the air outlet duct 30 connected to the housing 200 is large, the noise reduction piece 40 covers the air outlet 31, the area of the noise reduction piece 40 is also large, and the noise reduction and silencing effects are better. Meanwhile, the flow velocity of the air flow at the air outlet 31 is small, and the influence of the air flow blown out by the fan assembly 100 on the surrounding environment of the sweeping robot 1000 is also small.

The air outlet section 131 may be formed by extending from the outlet 12 of the fan 10 to a tangential direction of rotation of the blower 14. Therefore, the air flow formed by the rotation of the air blower 14 can be smoothly blown out by the air outlet section 131, and energy loss caused by convection is avoided. The air outlet section 131 is communicated with the air outlet duct 30, and the air outlet duct 30 is communicated with the air outlet 31.

Referring to fig. 3-6, in some embodiments, the fan assembly 100 further includes a first sealing member 60, and the first sealing member 60 is disposed at an outer edge of the fan 10 and covers the air outlet section 131.
