Multi-protection treatment system for preventing infection

The invention provides an anti-infection multi-protection treatment system which comprises a second air filtering device, the second air filtering device comprises a first air channel and a second air channel, an impeller is arranged in the second air channel, and the other end of the second air channel is hinged to a baffle and a locking assembly used for locking the baffle to a first position. In the first position, the baffle shields the second air channel, and when the pressure difference between the internal air pressure of the second air channel and the external air pressure reaches a preset value, the locking assembly can release the baffle; the roller shafts are arranged on the two opposite sides of the cavity respectively, the two ends of the filter layer are wound on the two roller shafts respectively, and one roller shaft is in transmission connection with the impeller; by means of the arrangement mode, air can be filtered through the filtering layer, the filtering layer is automatically driven to
