[0029] In this embodiment: when it is necessary to install the purification box 401, the purification box 401 is inserted into the base box 1. The moving block 503 is loosened by hand, so that the moving block 503 in the reset state moves downward along the outer wall trajectory of the protrusion 502. The moving block 503 in the descending state then moves the locking block 505 into the locking key 506. The locking key 506 and the locking block 505 in the engaged state lock the position of the purification box 401, thereby completing the installation of the purification box 401 and facilitating the disassembly and replacement of the purification box 401.

[0037] In this embodiment, the purification box 401 in its installed state purifies rainwater, thereby effectively improving the purification effect on rainwater.

[0038] Working principle: When the purification box 401 needs to be installed, the purification box 401 is inserted into the base box 1. The moving block 503 is loosened by hand, so that the moving block 503 in the reset state moves down along the outer wall trajectory of the protrusion 502. The moving block 503 in the descending state moves the locking block 505 into the locking key 506. The locking key 506 and the locking block 505 in the engaged state lock the position of the purification box 401, thus completing the installation of the purification box 401 and facilitating the disassembly and replacement of the purification box 401.

[0039] Since the purification box 401, filter screen 402, biochar composite matrix layer 403 and zeolite filter layer 404 are arranged sequentially from top to bottom inside the base box 1, the filter screen 402 filters impurities in the rainwater, the biochar composite matrix layer 403 adsorbs organic matter and modifies the biochar matrix, and the ions in the zeolite filter layer 404 exchange and remove trace elements in the rainwater. Thus, the purification box 401 in the installed state purifies the rainwater. The above structure effectively improves the purification effect of rainwater.
