Air purifier

The utility model relates to the technical field of indoor air purification, in particular to an air purifier. The air purifier comprises a shell, a draught fan and multiple air outflow channels. Multiple air outlets are formed in the side wall of the shell. One air outlet is communicated with one end of the corresponding air outflow channel. The other ends of the air outflow channels are communicated with the draught fan. An obtuse angle is formed between each air outflow channel and the side wall of the shell. By the adoption of the air purifier, the air outflow channels are arranged in the shell, and the obtuse angle is formed between each air outflow channel and the side wall of the shell. When the air purifier is used, the draught fan sends filtered air into the air outflow channels. Due to the fact that the obtuse angle is formed between each air outflow channel and the side wall of the shell, the filtered air is of an arc shape in the air outflow channels, after the filtered air flows out from the air outflow channels, vortexes are formed and mixed with indoor air, the purified air is quickly mixed with the indoor air, the indoor air is quickly purified, and purification efficiency is improved.
