Document Type and Number:
WIPO Patent Application WO/2023/020376
Kind Code:
A1
Abstract:
Disclosed are an air purification device, and a purification assembly and a humidification module thereof. A filter module (210) comprised by the purification assembly (20) surrounds the periphery of the humidification module (220). The humidification module (220) comprises a water tank (222), a humidification layer (2212), and a pump assembly (223), a flow channel (224) also being provided on the humidification module (220). The pump assembly (223) is used to extract the liquid from the water tank (222) into the flow channel (224) to wet the humidification layer (2212). Furthermore, excess liquid may flow back into the water tank (222) through the flow channel (224), thereby forming a water circulation system. After being purified by the filtering module (210), external air can be purified and humidified again by means of the wetted humidifying layer (2212), thereby having the beneficial effects of simultaneous purification and humidification, effectively increasing air quality.
