Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an indoor air purification device. Background Art

[0002] Indoor air purifier is a new type of household appliance that can purify indoor air and effectively improve the cleanliness of the air. Using an air purifier indoors is a very effective way to improve indoor air quality and create a healthy and comfortable office and residential environment.

[0003] Existing indoor air purification usually uses an activated carbon filter. Since the activated carbon filter is usually installed inside the device and is not easy to replace or disassemble, the filtering function will be greatly reduced if it is not replaced or cleaned for a long time. In addition, the existing air purification device usually has a dust screen at the air inlet to prevent a large amount of dust or larger impurities from being sucked into the air purification device. Since the dust screen may be blocked after long-term use, when the dust screen is blocked, the air purification efficiency will also be reduced. The dust screen needs to be manually cleaned regularly, which greatly reduces the practicality of the device. In view of this, we propose an indoor air purification device. Utility Model Content
