Immerse into the interior of the body, and the screen is fixed by the side frames (802) on both sides and the side plates (805) fixed inside the chassis (1) to realize the position fixation of the copper slag pollutants; Step 4: After positioning the screen (801), connect the external wiring (6) of the chassis (1) to the external power supply, and then close the box cover (701); when the box cover (701) is closed When the box cover (701) is pressed, the movable block (708) is displaced through the guide block (706), so that the guide block (706) is in contact with the push switch (705) so that the push switch (705) is pressed, and the box The catalytic lamp (703) installed on the cover (701) lights up, so that the catalytic lamp (703) performs photocatalytic degradation on the internal liquid medicine and copper slag pollutants.
