Title:
WATER-AIR SEPARATION STRUCTURE AND WATER SUCTION BRUSH HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/135914
Kind Code:
A1
Abstract:
A water-air separation structure and a water suction brush (1). The water-air separation structure comprises: a hollow water collection cup (15), which is open at the top to form an opening and is used for collecting sewage after water-air separation; and a water-air separation assembly (18), connected to the top of the water collection cup (15) to close the opening, the water collection cup (15) being provided therein with a water inlet pipe (152) extending upward from the bottom of the water collection cup in the axial direction, the outer wall of the water inlet pipe (152) and the inner wall of the water collection cup (15) being spaced from each other to form a water storage space therebetween, the water collection cup (15) being communicated with the outside by means of the bottom of the water inlet pipe (152), and the top of the water inlet pipe (152) being connected to the water-air separation assembly (18). The structure design with the air flow direction opposite to the water falling direction increases the water-air separation rate as much as possible, thereby preventing water from coming out from the air outlet, and preventing subsequent risks such as being difficult to clean the pipeline due to sewage enrichment and motor short-circuit.
