[0007] Preferably, the elastic clip is stamped from elastic thin steel plate, one end of which is stamped into an inverted Z-shaped structure with a handle, and the other end is stamped into double rows, one of which has a hook, and the subsequent part is stamped into a locking end of an R-shaped structure.

[0008] Preferably, the fixing assembly includes a cylindrical bracket, a pressure plate, a washer, a nut, and a positioning column. One end of the cylindrical bracket is welded to the porous plate, and the other end is tapped with a thread. The nut and the thread of the cylindrical bracket form a connecting pair.

[0011] Working principle: The locking end of the elastic clip is inserted into the fine filter frame of the fine filter. Under the combined action of the elastic force of the arc on the locking side and the hook, the elastic clip can be prevented from slipping out of the fine filter frame of the fine filter due to external force; the coarse filter is inserted between the convex surface of the handle of the elastic clip and the fine filter frame of the fine filter. The convex surface of the handle of the elastic clip applies a horizontal force to it, so that the coarse filter and the fine filter are tightly against each other, so that the two share a porous plate. On the other hand, a filtering system is provided, which includes a porous plate, multiple elastic clips, multiple coarse filters and fine filters, and multiple fixing components. The elastic clip makes the coarse filter and the fine filter tightly against each other. The fine filter is installed in the square hole of the porous plate.
