s4, when the active carbon adsorption plate (19), the photocatalyst plate (21) and the HEPA filter screen (23) need to be replaced, the cover (15) is rotated reversely, the cover (15) is not connected with the external thread (16) in a threaded manner any more, then the cover (15), the screw rod (22), the active carbon adsorption plate (19), the photocatalyst plate (21) and the HEPA filter screen (23) are integrally taken down, then the nut (20) is rotated one by one, the nut (20) is separated from the screw rod (22), and then the active carbon adsorption plate (19), the photocatalyst plate (21) and the HEPA filter screen (23) can be taken down one by one for replacement.
