A smart air purification device having a dehumidification function comprises a heat pump device (1), a water collection device (2), a controller (3), and a housing (4). The heat pump device (1) comprises a compressor (5), an evaporator (6), a first radiator (7), a second radiator (8), an electromagnetic valve (9), a one-way valve (10), an expansion valve (11), and a fan (12). Surfaces of the evaporator (6), the first radiator (7), the second radiator (8), and a water collection tank (14) are coated with nanometer titanium dioxide layers. The fan (12), the evaporator (6), the first radiator (7), and the second radiator (8) are disposed between an exhaust opening (19) and an air inlet (20). The water collection tank (14) is located between the evaporator (6) and the first radiator (7). The second radiator (8) is located between the fan (12) and the evaporator (6). During operation, an ultraviolet lamp tube (21) is turned on, and nanometer titanium dioxide coating the surfaces of the first radiator (7), the second radiator (8), the evaporator (6), and the water collection tank (14) exerts a catalytic activity, to remove hazardous substances such as formaldehyde from the air, kill various malignant bacteria, and achieve the purpose of purifying the air. Moreover, repeated dehumidification is performed by means of the first radiator (7), the second radiator (8), and the evaporator (6), and the dehumidified air can be used in a heating manner and a refrigeration manner alternately. |
