[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 3As shown, a filter that can be easily disassembled and assembled includes a shell and a filter element 5 arranged in the shell. The filter element 5 is square, and includes a frame and a filter screen arranged on the frame. The shell includes side panels 4 and a top panel 3 corresponding to the side surfaces of the filter element 5. The top panel 3 and the four side panels 4 form a receiving groove with an opening at the lower end, and the filter element 5 is arranged in the receiving groove. A frame 1 is provided on the side panel 4, and a pressing block 2 for pressing the filter element 5 is provided on the frame 1; the frame 1 includes an outer panel 11 arranged on the outer side of the side panel 4, an inner panel 12 arranged between the side panel 4 and the filter element 5, and a concave portion 13; the outer panel 11 is connected to one end of the concave portion 13, and the inner panel 12 is connected to the other end of the concave portion 13, and the side panel 4 is located between the outer panel 11 and the inner panel 12; the concave portion 13 is provided with a slot 134 on the side facing the filter element 5, and the concave portion 13 includes a first U-shaped plate 131 and a The second U-shaped plate 132, one end of the first U-shaped plate 131 is connected to the inner plate 12, one end of the second U-shaped plate 132 is connected to the outer plate 11, the other end of the first U-shaped plate 131 is connected to the other end of the second U-shaped plate 132 through a connecting plate 133, the first U-shaped plate 131, the second U-shaped plate 132 and the connecting plate 133 surround the slot 134; the outer plate 11, the inner plate 12 and the concave portion 13 are formed by bending sheet metal, the first U-shaped plate 131 and the second U-shaped plate 132 have a certain elasticity and can clamp the pressing block 2.
