As one optional embodiment of the application, the top end and the bottom end of the closed frame are respectively clamped at the outer side of the opening of the main body, and the closed frame is connected to the main body through screws.

The technical scheme is realized, a concrete structure for disassembling and connecting the closed frame is provided, and when the closed frame is required to be disassembled, only the screws are required to be disassembled.

As one of the optional embodiments of the present application, a side surface of the sealing frame facing the filter element is provided with a sealing groove, and an outer side wall portion of the inner frame is clamped in the sealing groove.

The technical scheme is realized, the horizontal end of the inner frame is also better sealed, the sealing effect is further improved, and the filtering function is ensured.

In summary, the present application includes at least one of the following beneficial technical effects:

through the frame design become the main part with dismantle the closed frame of connection in the main part, only need dismantle the closed frame earlier can be convenient take out the filter core when the later stage dismantles the filter core, effectively improve maintenance convenience, reduce maintenance cost.
