[0015] Reference Figure 1-3According to an embodiment of the utility model, a high-efficiency filter air supply port comprises a box body 1, wherein the box body 1 is provided with an air vent 16 which passes through from top to bottom, wherein the air vent 16 is movably connected with a lifting mounting frame 3, and the left and right sides of the air vent 16 are symmetrically provided with limited sliding grooves 4, wherein the limited sliding grooves 4 are slidably connected with a limited sliding block 6 which is fixedly connected with the lifting mounting frame 3, and a dust removal box 5 is fixedly provided at the middle position of the lifting mounting frame 3, and the left and right sides of the lifting mounting frame 3 are provided with a locking mechanism which is fixedly connected with the box body 1 near the bottom position, so as to realize the stable locking installation of the lifting mounting frame 3 and the box body 1, and the locking mechanism comprises an embedded groove 8 and a wedge-shaped locking block 9 which is slidably connected and arranged in the embedded groove 8, and the left side The embedded groove 8 is arranged opposite to the limited slide groove 4 on the left side, and the embedded groove 8 on the right side is arranged opposite to the limited slide groove 4 on the right side. The wedge-shaped locking block 9 is pressed and connected with a pressing spring 10 on the side away from the limited slide groove 4. A connecting groove 11 is provided at the bottom of the embedded groove 8. A connecting rod 12 extending up and down is slidably connected in the connecting groove 11. The top of the connecting rod 12 is fixedly connected to the wedge-shaped locking block 9. An inner groove 13 is provided at the bottom of the connecting groove 11. The bottom end of the connecting rod 12 extends into the inner groove 13. The lifting mounting frame 3 is unlocked by toggling the connecting rod 12, so that the lifting mounting frame 3 can be pulled out downward conveniently, and the pull-out filter assembly 7 in the dust removal box 5 can be taken out and replaced conveniently.

[0016] Advantageously or exemplarily, an air supply main unit 2 is fixedly mounted at the top opening of the vent 16, thereby achieving rapid directional control of air flow.

[0017] Advantageously or exemplarily, the dust removal box 5 is provided with a pull-out slide groove 17 opening forward, and a pull-out filter assembly 7 is slidably connected in the pull-out slide groove 17. A handle 18 is fixed on the front side of the pull-out filter assembly 7 for easy pulling.

[0018] Advantageously or exemplarily, a plurality of groups of equally spaced air guide plates (not shown) are provided at the bottom opening of the lifting mounting frame 3 to thereby divert the air.

[0019] Beneficially or exemplarily, a closing cover 14 is provided in the inner groove 13, and a positioning groove 15 is provided on the top of the closing cover 14, thereby shielding the inner groove 13 to improve the design aesthetics.
