[0006] A mounting seat, a filter frame is fixedly bonded on the rear side wall of the mounting seat, a slot is provided on the top wall of the filter frame, a pair of mounting slots are provided on the filter frame, and filter nets are movably inserted in the pair of mounting slots, a covering plate is movably inserted on the slot, a first groove is provided on the top wall of the covering plate, a limiting mechanism is provided on the covering plate, the limiting mechanism includes two sliding rods, both of the sliding rods are slidably connected to the covering plate, both of the sliding rods are arranged in the first groove, a pull rod is fixedly bonded on the top end of the two sliding rods, and tension springs are sleeved on the two sliding rods, and both ends of the tension springs are respectively fixedly connected to the bottom wall of the first groove and the pull rod, and a pair of limiting grooves are provided on the bottom wall of the slot, and the limiting grooves are adapted to the sliding rods.

[0007] Preferably, two second grooves are provided on the inner wall of the top side of the filter frame, and blocks are fixedly bonded to the two sliding rods, and the blocks are slidably connected in the second grooves.

[0008] Preferably, sealing rings are fixedly bonded to the front and rear side walls of the filter screen.

[0009] Preferably, the mounting seat is provided with four mounting holes, and the four mounting holes are respectively arranged at the four corners of the mounting seat.

[0010] Preferably, a handle groove is provided on the top wall of the filter screen.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model cooperates with the slots, cover plates, slide bars, pull bars, tension springs and limit grooves provided on the filter frame. When the filter screen needs to be disassembled and assembled during use, the pull bar can be pulled upwards, and the pull bar drives the two slide bars to slide upwards and disengage from the limit grooves, thereby releasing the limit on the cover plate. Thereafter, the cover plate can be slid backwards to pull out the cover plate, and then the filter screen can be pulled out in sequence through the handle grooves, thereby realizing rapid disassembly and assembly of the filter screen, facilitating cleaning or replacement of the filter screen. The overall structure is simple, and the disassembly and assembly operation is convenient, which greatly improves the work efficiency of disassembly and assembly of the filter screen.
