Claim 8:
9. A spliceable and foldable filter element device, comprising: a quadrilateral filter element body, left frame body, a right frame body, an upper frame body, a lower frame body, a clamping rod;
wherein the left frame body and the right frame body are respectively disposed on a left side and a right side of the quadrilateral filter element body; the upper frame body and the lower frame body are respectively disposed on an upper side and a lower side of the quadrilateral filter element body; the clamping rod is disposed between the left frame body and the right frame body, the clamping rod comprises a transverse rod, and clamping teeth are disposed on the transverse rod; the quadrilateral filter element body is a folding layer having vertical folds, and the clamping teeth are matched with the folding layer;
wherein each of the left frame body, the right frame body, the upper frame body, and the lower frame body comprises: an elongated plate and two baffle sheets respectively disposed at two opposite sides of the elongated plate: the elongated plate and the two baffle sheets together define an elongated groove, and a width of the elongated plate in a direction from one of the two baffle sheets to the other of the two baffle sheets is less than a spacing between the two baffle sheets: a slot is defined between one of the two baffle sheets and a side of the elongated plate facing towards the one of the two baffle sheets: a corresponding one of the left frame body, the right frame body, the upper frame body, and the lower frame body is clamped on the quadrilateral filter element body through the slot; and the quadrilateral filter element body is partially accommodated in the elongated groove.
