Further, a plurality of filtering holes are arranged on the first annular member 11, and the second annular member 12 is of a closed type filter-hole-free design. This application sets up to having the filtration pore through the metal ring unit with the outer lane, the plastics ring unit of inner circle sets up to closed no filtration pore design, avoided current plane filter screen rivers to easily reveal on drain pump motor or the cable cause the electric leakage, the problem of incident such as electric shock, the plane filter screen that has also solved current panel beating integrated into one piece simultaneously makes into partly has the filtration pore, the structure in some no filtration pore, the shaping is very difficult, the difficult problem of realizing.

Further, as shown in fig. 3 to 6, a protruding riveting structure is disposed on the second ring member 12, the riveting structure is disposed on the second ring member 12 located at the overlapping portion of the first ring member 11 and the second ring member 12, a riveting hole 1131 matched with the riveting structure is correspondingly disposed on the first ring member 11, the riveting structure passes through the riveting hole 1131, the outer periphery of the second ring member 12 and the inner periphery of the first ring member 11 are overlapped and tightly attached, and the portion of the riveting structure passing through the riveting hole 1131 is pressed and fixed at the outer periphery of the riveting hole 1131 by a thermal fusion method, so that the first ring member 11 and the second ring member 12 are fused with each other, and the first ring member 11 made of metal and the second ring member 12 made of plastic are firmly connected into a whole and have better sealing performance.

Further, the caulking structure is a plurality of projections provided on the upper/lower surface of the second ring 12 at intervals along the circumference of the second ring 12. Preferably, the protrusion is a plurality of riveting holes 1131, and the shape and size of the riveting holes 1131 match the shape and size of the outer periphery of the protrusion, and the protrusion is a riveting column 1211 or a riveting rib or other vertical structure that is injected at intervals on the circumference of the second annular member 12. The riveting holes 1131 are arranged along the circumferential direction of the first ring-shaped member 11 corresponding to the positions of the protrusions, the riveting holes 1131 are arranged in one-to-one correspondence with the protrusions, and the protrusions respectively penetrate through the riveting holes 1131. In this application, a plurality of archs that second ring member 12 circumference set up pass riveting hole 1131 on the first ring member 11 respectively, the arch passes riveting hole 1131's part compresses tightly through the mode of hot melt and fixes the periphery of riveting hole 1131 to make first ring member 11 and the whole week of second ring member 12 upwards homoenergetic fuse each other, compact structure, whole complex is more firm, improves the leakproofness between first ring member 11 and the second ring member 12, reduces the probability of leaking between first ring member 11 and the second ring member 12.

Preferably, the protrusions are a plurality of cylindrical riveting columns 1211 disposed on the upper/lower surface of the second ring member 12, the riveting columns 1211 are integrally formed with the second ring member 12, and the riveting holes 1131 are circular through holes opened on the first ring member 11 and having an inner diameter matching with the outer diameter of the riveting columns 1211. The application provides a plane filter screen, the connection structure of first loop forming element 11 and second loop forming element 12 adopts cylindrical riveting post 1211 and circular riveting hole 1131 hot riveting complex mode, and connection structure shape is regular, changes in machine-shaping more, and because riveting post 1211 has certain longitudinal extension length, more conveniently alternates in riveting hole 1131 with the cooperation of riveting hole 1131 for first loop forming element 11 and second loop forming element 12 complex are more firm.

This application adopts two sets of moulds when making the plane filter screen, processes out the first loop forming element 11 of metal material and the second loop forming element 12 of plastics material respectively according to shape, model as required, reserve processing out riveting hole 1131 on the first loop forming element 11 of metal material, reserve processing out plastics riveting post 1211 or riveting protruding muscle or other vertical structure on the second loop forming element 12 of plastics material, wait to carry out the erection joint again after first loop forming element 11 and the cooling of second loop forming element 12. The plastic riveting columns 1211, the riveting convex ribs or other vertical structures reserved on the second annular piece 12 made of the plastic material correspondingly penetrate through the riveting holes 1131 reserved on the first annular piece 11 made of the metal material, the part of the riveting structure penetrating through the riveting holes 1131 is pressed and fixed on the periphery of the riveting holes 1131 in a hot melting mode, and after the riveting structure is heated, melted and softened, the riveting structure is pressed, cooled and reshaped through a special metal forming rivet head and clamped tightly, so that the first annular piece 11 and the second annular piece 12 are completely matched. In this application, assemble again after first annular member 11 and the cooling of second annular member 12, two can not take place to warp because of the cooling shrink, have avoided recooling behind current metalwork and the working of plastics be assembled between/be connected effectively, and two piece cooling deformation that lead to the fact cooperate badly, and sealed effect variation seriously can lead to the problem that whole plane filter screen warp.

The application provides a plane filter screen structure is connected fixedly through hot riveting's mode, replaces supplementary fastening connection spare such as fastening connection spare, screw, hasp and filling solder, and simple process reduces assembly cost, and material consumption is low, and the shaping is fast, raises the mechanized processing of efficiency, easy operation, and precision is high.

Further, as shown in fig. 3 to 6, the first annular member 11 includes a first annular surface 111, a transition surface 112 formed by extending an inner edge of the first annular surface 111 obliquely downward, and a first annular overlapping surface 113 formed by extending a lower edge of the transition surface 112 horizontally inward. The second loop member 12 overlaps below the first loop overlap surface 113. The second annular part 12 comprises a second annular surface 121 and an annular matching surface 122 which is formed by obliquely and outwardly extending the outer edge of the second annular surface 121 and covers the transition surface 112, the annular matching surface 122 covers the periphery of the transition surface 112 and plays a certain sealing role, the phenomenon that water flows out along a gap between the second annular surface 121 and the lower part of the first annular overlapping surface 113 is effectively avoided, and the sealing performance is improved. The outer peripheral part of the second annular surface 121 is lapped below the first annular lapping surface 113, the riveting structure is arranged on the upper surface of the second annular surface 121, which is lapped with the first annular lapping surface 113, of the second annular surface 121, the riveting hole 1131 is correspondingly formed in the first annular lapping surface 113, the contact area of the first annular part 11 and the second annular part 12 is increased through a lapping matching mode of surface-to-surface contact of the first annular lapping surface 113 and the second annular surface 121, so that the first annular part 11 and the second annular part 12 can be attached more closely during hot riveting, the structure is more compact, and meanwhile, the sealing effect is further improved.

The present embodiment also provides a variant of the solution described above, namely a solution in which said first annular element 11 overlaps below said second annular element 12.
