Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Referring to figs. 1 to Fig. 4, a kind of air filter, including the first frame 1, the second frame 2, main filter core 3 and secondary filter core 4；
First frame 1 is provided with the receiving cavity 10 extended outward, and the receiving cavity 10 has bottom wall 10a, second frame
Frame 2 is provided with the annular convex platform 20 extended outward, and the filter screen 30 is arranged in the receiving cavity 10, the annular convex platform
20 protrude into the receiving cavity 10, compress the edge of the filter screen 30, the pair filter core 4 includes more than one piece filter disposed in parallel
Piece 40, the filter disc 40 are removably disposed in second frame 2, and the outer surface of the filter disc 40 is coated with hot melt adhesive tablet
Layer.
The main filter core 3 includes filter screen 30 and fixed frame 31；The filter screen 30 is arranged in the fixed frame 31；Institute
The section of filter screen 30 is stated in undaform, any one structure of sawtooth pattern or English alphabet " X " type；Second frame 2
Two opposed inner walls are provided with skewed slot 21, and the filter disc 40 is connected in the skewed slot 21；First frame 1 and second frame
