[0006] To solve the above technical problems, the utility model provides the following technical scheme: a one-way flow mute fan, comprising a fan housing and a back plate detachably installed on one side of the fan housing;

[0007] A fan body is installed on one side of the fan housing through a mounting bracket, and a plurality of filter cartridge assemblies are equidistantly arranged on the other side of the fan housing. An air inlet end pipe and an air outlet end pipe are respectively installed on one end of the fan housing near the fan body and one end of the fan housing near the filter cartridge assemblies.

[0008] Preferably, the filter core assembly comprises a C-shaped mounting frame fixedly arranged on one side of the fan housing, and a fixed frame abutting against the back plate is detachably mounted on the side of the C-shaped mounting frame.

[0009] Preferably, a limiting groove is formed in the C-shaped mounting frame and the fixed frame, and a filter layer is arranged in the two limiting grooves.

[0010] Preferably, an insertion key is arranged at each end of the side of the fixed frame facing the C-shaped mounting frame, and an insertion slot is formed at each end of the C-shaped mounting frame for the insertion key.

[0011] Preferably, the filter layer can be one of a sintered activated carbon particle layer, a non-woven fabric layer and a gauze layer.

[0012] Preferably, two mounting ears are symmetrically arranged on the two sides of the fan housing.
