The invention relates to an apparatus cleaning device for the pneumology department. According to the apparatus cleaning device for the pneumology department, a plurality of sets of planetary wheel structures are ingeniously applied, and the structural specificity of an external gear ring is utilized to convert forward and reverse rotating of a motor into different working processes; through the incompleteness of inner teeth of the external gear ring, when the external gear ring is about to be disengaged from a driven gear at a meshing terminal, a set of pre-tensioning device is added, and then the external gear ring is limited at the position of the meshing terminal of the external gear ring and the driven gear wheel, and reliable meshing can be realized when the external gear ring rotatereversely; and meanwhile, transition grooves and rectangular grooves in different positions are made alternately communicate through relative rotation of a circle plate and a fixing plate, and different processes are achieved. According to the apparatus cleaning device for the pneumology department, the transmission characteristics of a screw rod and a reciprocating screw rod are fully utilized to realize reciprocating characteristics of tracheal intubation and cleaning and drying work, the design is ingenious, the operation is simple, cleaning personnel are liberated greatly, working difficulty of the cleaning personnel is lowered, and the cleaning effect is excellent.
