At this time, the filter mesh roll 25 can move, and then the drive motor 211 is started, and the drive motor 211 drives the reel. The roller 21 rotates, and the take-up roller 21 drives the filter mesh roll 25 to be wound during the rotation, thereby pulling the filter mesh roll 25 to move, so that the filter mesh roll 25 on the upper take-up roller 24 replaces the filter mesh roll 25 inside the filter chamber 14, thereby ensuring the filtration efficiency of the filter mesh roll 25. When the filter mesh roll 25 on the upper take-up roller 24 is used up, the filter mesh roll 25 is completely collected on the take-up roller 21. At this time, the doors 11 on both sides of the shell 12 are opened to remove the filter mesh roll 25 on the take-up roller 21, and at the same time, a new unused filter mesh roll 25 is put on the upper take-up roller 24 on the other side of the shell 12, so that one end of the filter mesh roll 25 passes through the filter chamber 14 and is connected to the take-up roller 21 for reuse.
