s2, the atomized disinfectant entering the cavity enters the air guide strip (41) through the air inlet (42), moves to one end of the air guide strip (41) along the arc-shaped air guide strip (41), enters the detection tank through the air outlet (43) and the air outlet (111), disinfects the side wall of the detection tank, when the gas coming out of the air outlet (111) leaves the outer tube (11) along the track of the air outlet (111), the gas moves in the detection tank along the track of the spiral air outlet (111), blows the dead angle or crack position of the detection tank, the gas enters the upper side of the connecting plate (19) through the air vent (18) at the bottom of the detection tank, the impurities flushed by the disinfected gas in the detection tank fall into the object collecting tank for collection, the gas enters the inner tube (12) through the guide of the connecting disc (13), and enters the exhaust cavity (15) through the communicating tube (16) along the track of the inner tube (12), the gas entering the exhaust cavity (15) leaves the device through an exhaust port (141) to sterilize a platform for placing a detection sample for the biological detector;

s3, the downward moving pressing frame (65) drives the sliding ring (64) to move downward, the downward moving sliding ring (64) pushes the scraping ring (61) to move downward, the scraping ring (61) scrapes the outer side wall of the outer tube (11) to remove liquefied water drops on the outer side wall of the outer tube (11), the downward moving scraping ring (61) enables the scraping ring (61) to rotate downward on the outer side of the outer tube (11) through the matching of the arc groove (62) and the thread strip (7), and the brush disc (63) brushes the side wall of the detection groove.
