The cabinet body 10 is a hollow structure, and in this embodiment, the cabinet body 10 is actually a wardrobe for placing clothes, and the cabinet body is combined with an air purification structure, so that indoor air purification can be realized without adding extra space. Preferably, the customization is adopted, so that the shape of the house can be completely matched, and the indoor space is utilized to the maximum extent.
In the cabinet body 10, a first purifying room 11, a second purifying room 12 and an induced draft room 13 are arranged and are sequentially communicated, the first purifying room 11 is used for first-step purification and filtration of air, the second purifying room 12 is mainly used for removing formaldehyde in the air, and the induced draft room 13 is a power source for enabling indoor air to enter.
