The inner side surface of the filter element body 4 is surrounded by the upper end cover 1, the base 2 and the side panels 3. The inner cavity formed is recorded as the clean side and the outer side is the dirty side. The connection between the upper end cover 1, the base 2 and the side panels 3 is provided with an assembly hole 10, and is connected by a rivet 5 passing through the assembly hole 10. Figure 13 The outer side of the filter element body 4 is flush with the waistline of the side plate body 7 ( Figure 5 ), Figure 7 It is a structural diagram of the upper end cover. Figure 8 This is a cross-sectional view of the upper end cover. The upper end cover 1 includes an upper end plate 12, which is provided with a through hole 8 connected to the clean side.

[0048] In the manufacturing process of the filter core, the sponge strips are pasted to fill adhesive in the functional areas that need to be sealed and fixed and are reinforced by rivets, thereby reducing the amount of adhesive used in the production process of the filter core, greatly reducing the manufacturing cost of the filter core, further improving the strength of the filter core, and making the filter core meet the needs of various application scenarios and different shock load impacts. Specifically, adhesive 9 is first filled in the first sealing area of one side, and after the adhesive 9 solidifies, the same method is used to bond the other side plate body 7. The bonding effect is as shown in Figure 12 . Then, adhesive 9 is filled in the second sealing area and the third sealing area, and the corresponding surfaces of the filter core body 4 after bonding the side plates (as shown in Figure 12 ) are placed in the corresponding second sealing area and third sealing area. The filter core body 4 is fixed and the adhesive is solidified. After bonding is completed, the filter core is reinforced by assembling rivets 5.

[0049] The high-efficiency low-resistance trapezoidal filter element in the embodiment can be used for air filtration of the air inlet end of a large air compressor, but is not limited to air filtration of the air inlet end of a large air compressor. The filter element is designed in a trapezoidal shape, adopts a sheet metal shell, and the shell is reinforced by using a bonding and riveting process. In the manufacturing process of the filter element, glue is filled in the functional areas that need to be bonded and fixed by pasting sponge strips and other media, the amount of glue needed for filter element production is reduced, and thus the manufacturing cost of the filter element is greatly reduced.
