Domestic negative-ion humidification and purification device with replaceable purification media

The invention discloses a domestic negative-ion humidification and purification device with replaceable purification media. The negative-ion humidification and purification device is a column which is horizontally placed. An air inlet is formed in the left end of the negative-ion humidification and purification device, and a hole is formed in the upper portion of the right end of the negative-ion humidification and purification device. A centrifugal impeller is installed on the hole. A negative ion generator, a particle filtering device, a fan, an ultraviolet lamp, an organic matter filtering device and filtering cotton are installed in the negative-ion humidification and purification device in sequence from left to right. The particle filtering device and the organic matter filtering device are hinged to a shell and rotatably pulled in the shell. A water inlet used for adding water to the filtering cotton is formed in the upper portion of the shell. The domestic negative-ion humidification and purification device is simple in structure, reasonable in arrangement and low in manufacturing cost; purification media can be replaced at any time according to requirements and the use condition and be selectively placed according to the indoor air condition, so that purification requirements of users are met in different aspects; air is humidified while the air is purified, and the humidification function is achieved while air purification is achieved.
