The air inlet of the fresh air channel is opposite to and communicated with the first through hole, and the air outlet thereof is communicated with the second air inlet. The invention allows outdoor fresh air to be introduced into the casing through the fresh air channel, thereby avoiding the problem that unpurified outdoor fresh air pollutes the inside of the casing.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an indoor air purifier. Background technique [0002] In the existing indoor air purifiers with the function of fresh air replacement, in the process of introducing outdoor fresh air, since there is no dedicated air duct, the unpurified fresh air will dirty the inside of the machine. When the user replaces the filter element, he will find that The inside of the whole case is full of dust, which is inconvenient to clean. Due to the unreasonable layout of the existing air purifiers, there are defects of high noise and small air volume. When people use them, the indoor noise is too large and the air purification effect is not ideal, which cannot well meet people's normal life needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an indoor air purifier aiming at the deficiencies of the prior art.

Problems solved by technology

[0002] In the existing indoor air purifiers with the function of fresh air replacement, in the process of introducing outdoor fresh air, since there is no dedicated air duct, the unpurified fresh air will dirty the entire interior of the machine. When the user replaces the filter element, he will find that The inside of the whole case is full of dust, which is inconvenient to clean

Due to the unreasonable layout of the existing air purifier, there are defects of high noise and small air volume. When people use it, the indoor noise is too large and the air purification effect is not ideal, which cannot well meet people's normal life needs.
