Indoor air purifying and humidity adjusting device

The invention provides an indoor air purifying and humidity adjusting device and belongs to the technical field of environment management devices. According to the structure, the indoor air purifying and humidity adjusting device comprises a main control circuit (1), an air pump (2), a filter tank (3), filter screens (4), a water pump spray nozzle (5), ultrasonic humidifiers (6), a gas condenser pipe (7) and a filtrate collector (8). The water pump spray nozzle (5) compresses water from the filtrate collector (8) and sprays the water in the filter tank (3) from top to bottom, and the ultrasonic humidifiers (6) on the upper portion of the interior of the filter tank (3) are started at the same time so that part of water can be gasified. When water mist and water drops flow from top to bottom, the air pump (2) on the lower portion of the filter tank (3) is started at the same time, and outdoor air is compressed inwards. Filtrate flows into the filtrate collector (8) after being filtered. The indoor humidity can
