That is, at least part of the side shell 113 can be disassembled to expose the cavity 12 to facilitate the installation or removal of the filter element 2, thereby facilitating the replacement and cleaning of the filter element 2. The operation is simple and ensures that the filter element 2 is located in the installation structure 1. Improve the filtration performance, avoid cumbersome replacement of the filter element 2, which may cause dust accumulation and affect the filtration effect due to long-term use of the filter element 2.

Moreover, when the installation structure 1 with the filter element 2 is assembled on an air treatment device such as a bladeless fan, the upper and lower ends of the installation structure 1 will be docked with corresponding components. It is inconvenient to expose the upper and lower ends and need to be docked first. Disassembly of upper or lower parts. The filter element 2 of this embodiment can be disassembled and assembled from the side of the installation structure 1 without disassembly and assembly from the upper end or lower end of the installation structure 1. It is only necessary to disassemble at least part of the side shell 113, which is simple to operate.

Specifically, the mounting structure 1 also includes a support column 114 connecting the upper shell 111 and the lower shell 112 to increase the strength of the mounting structure 1 and improve the layout of the mounting structure 1 .

The side shell 113 is detachably provided on the support column 114. In this embodiment, there are two supporting pillars 114 , and the two supporting pillars 114 are arranged oppositely. The side shell 113 includes a first side portion 1131 and a second side portion (not shown) that are arranged oppositely.
