In this embodiment, the outer frame 22 is provided with a flange 221 bent upward on a side wall near the maintenance opening 11, and when the inner frame 21 is mounted, an outer side frame (a side frame provided with the handle 213) of the outer frame is located outside the flange 221, and a first connection hole 222 is provided on an outer side frame of the inner frame 21. When the inner frame body 21 is pushed inwards to enable the pressing plate 23 to press the upper surface of the filter 24, the locking structure is locked, so that the sealing between the filter 24 and the air outlet cavity 1 can be effectively ensured. When the filter 24 needs to be disassembled, the locking structure can be unlocked first, and the filter 24 can be taken out by pulling out the inner frame body 21.

In order to ensure the sealing effect between the filter 24 and the pressure plate 23, and between the filter 24 and the air outlet cavity 1, the pressure plate 23 and the filter 24 are tightly abutted, and the air outlet cavity 1 and the filter 24 are tightly abutted, a sealing element, such as a sealing gasket, may be arranged on the upper surface of the filter 24 or the lower surface of the pressure plate 23.

The air treatment system and the filter mounting structure provided by the embodiment of the application are very convenient to mount and dismount the filter, and the dismounting directions are all on the side surface of the air outlet cavity, so that the air treatment system and the filter mounting structure do not occupy upper and lower spaces, and can meet the mounting space requirements of most equipment. The sealing surface between the filter and the air outlet cavity is tightly pressed by the pressing plate, so that the filter and the air outlet cavity are tightly attached, the sealing effect is good, the operation is very simple, and the use of connecting pieces such as screws is reduced.
