Kind Code:
A1
Abstract:
A sewage collection assembly (100) and a base station used for a robot cleaner. The sewage collection assembly (100) comprises a sewage bucket (110) and a filtration basket (120). The sewage bucket (110) comprises a bucket body (111) and a bucket lid (112) covering a bucket opening of the bucket body (111). A first sewage inlet (113) and a first air outlet (114) are separately provided on positions, close to the top end, of the bucket wall of the bucket body (111). The filtration basket (120) has an open top end, and is provided with an airtight basket wall and a basket bottom provided with filtration holes (122), a second sewage inlet (121) being provided on a position, closed to the top end, of the basket wall. The filtration basket (120) is placed in the bucket body (111), and the upper periphery of the filtration basket (120) is tightly attached to the inner wall of the bucket body (111) so as to divide a bucket chamber into a first bucket chamber located above the filtration basket (120) and a second bucket chamber located below the filtration basket (120). The first sewage inlet (113) communicates with the first bucket chamber through the second sewage inlet (121), and the first air outlet (114) is located at a position close to the top end of the filtration basket (120) and communicates with the second bucket chamber. The sewage collection assembly (100) has a good gas-liquid separation effect, so that sewage is not liable to enter a draught fan and is prevented from damaging a draught fan.
