10. The method for assembling a clean space air purification device based on building construction according to any one of claims 1 to 9, characterized in that: S1: Deployment of the purification unit (2): Select a corner or edge area of ​​the building wall (1) within the construction space, position and install the main structure of the purification unit (2), ensure that it is tightly fitted with the three sides of the building wall (1) at the same time, use appropriate fasteners to firmly install the purification unit (2) on the wall, and install the core components such as the filter inside the purification unit (2); S2: Installation of the cleaning assembly (3): The upper end of the vertical pipe assembly (33) in the cleaning assembly (3) is pre-integrated or firmly installed at the dust outlet position preset at the bottom of the purification unit (2), ensuring that the connection is well sealed, the folding cover assembly (34) is above the vertical pipe assembly (33), and the initial state is closed, then the insert (324) in the guide connecting pipe assembly (32) is inserted from bottom to top into the lower end of the installed connecting pipe (331), and appropriate pressure is applied to ensure that the insert (324) is fully inserted into place, so that the elastic sealing ring (325) and the inner wall of the connecting pipe (331) form a reliable sealing connection, so that the internal channels of the two are connected and there is no leakage; S3: Adjustment of the cleaning component (3): The hand wheel (312) provided in the manual magnetic block (311) is used to screw the threaded plug (313) onto the internal thread interface of the threaded tube (321). The relative position of the magnetic block (311) and the threaded tube (321) is controlled by rotating the hand wheel (312). The threaded tube (321) is displaced by the magnetic repulsion force generated by the magnetic block (311) on the magnetic rod (323). The movement of the magnetic rod (323) drives the movement of the connecting rod (333). The movement of the connecting rod (333) controls the opening and closing size of the folding cover component (34). S4: Guided cleaning of dust accumulation inside the purification unit (2): When the dust accumulation inside the purification unit (2) needs to be cleaned after a long period of operation, the hand wheel (312) is rotated, and the hand wheel (312) drives the threaded plug (313) to rotate through the magnetic block (311). The spiral fit between the threaded plug (313) and the threaded tube (321) causes the threaded plug (313) to move axially. The magnetic block (311) moves as the threaded plug (313) moves, driving the magnetic rod (323) to move upward. The upward movement of the magnetic rod (323) drives the connecting rod (333) to move upward, and the connecting rod (333) drives the connecting seat (344) to move upward. The movement of the connecting seat (344) causes the left cover (3 43) is tilted up, and the folding cover assembly (34) is gradually opened. The dust accumulated inside the purification unit (2) falls into the connecting pipe (331) through the gap between the right cover plate (341) and the left cover plate (343) and the upper end opening of the connecting pipe (331) under the action of gravity and the airflow inside the purification unit (2), and enters the insert pipe (324) through the connecting pipe (331). Under the guidance of the insert pipe (324), the dust flows downward along its tube cavity and finally falls from the outlet of the insert pipe (324) in a preset direction. After cleaning is completed, the hand wheel (312) is rotated in the opposite direction to reset the plug (31), thereby driving the above-mentioned components to reset and completely close the dust discharge channel.
