Abstract:
A self-cleaning environmentally friendly air purification and dust-removal device, comprising a wall (1), a purifier pipe (2), and a dust exhaust pipe (14); the purifier pipe (2) is embedded in the wall (1); a first protective mesh (3), a dust filter mesh (4), a motor (5), a gas distribution plate (7), a first filter layer (8), a second filter layer (9), an air suction fan (10), and a second protective mesh (12) are sequentially provided from left to right in an inner cavity of the purifier pipe (2); a cleaning brush (13), which cooperates with the dust filter mesh (4), is fixedly connected to a motor shaft of the motor (5); several ventilation holes (71) are uniformly provided on the gas distribution plate (7); an opening at the top of the dust exhaust pipe (14) is provided with a third protective mesh (17); a dust exhaust fan (15) is provided inside the dust exhaust pipe (14). By providing the dust filter mesh (4), the first filter layer (8), and the second filter layer (9), air is filtered and purified in many stages, removing impurities such as dust from air, purifying air, and improving indoor air quality. Dust accumulated on the dust filter mesh is removed when the motor (5) drives the cleaning brush (13) to rotate; moreover, the dust exhaust fan (15) discharges air and discharges dust to outdoor air, preventing dust accumulation from affecting the filter effect of the dust filter mesh (4).
