Household air purifier with replaceable purification medium

The invention discloses a household air purifier with a replaceable purification medium. The air purifier is a horizontally arranged column body. An air inlet is formed in the left end of the column body, and an air outlet is formed in the right end of the column body. A particle filtering device, a fan, an ultraviolet lamp and an organic filtering device are installed in the air purifier sequentially from left to right, and the particle filtering device and the organic filtering device are hinged to an outer shell and are drawn and pulled rotationally from the inside of the outer shell. The household air purifier with the replaceable purification medium is simple in structure, reasonable in arrangement and low in manufacturing cost. The purification medium can be replaced anytime according to the needs and use conditions. Meanwhile, placement of the purification medium can be selected according to the indoor air conditions, the purification requirement of a user can be met from different aspects, and the household air purifier is convenient to use and meets the market requirements. In addition, the air is subjected to two purification treatments of illumination by ultraviolet light and catalysis by photocatalysts, so that the bacteria, virus, fungi and the like in the air can be effectively purified.
