Invasive breathing machine capable of preventing bacterium breeding

The invention relates to the technical field of invasive breathing machines, and discloses a bacteria breeding prevention invasive breathing machine which comprises an equipment body, an oxygen supply device is movably installed at the top of the equipment body, a disinfection box is movably installed at the top of the equipment body, and a plurality of flow control structures are installed on the left side of the disinfection box in a gear meshing mode. A sealing shell is movably mounted on the right side in the disinfection box, and a sealing box is arranged on the reverse side of the disinfection box. Through the cooperative use of the equipment main body, the oxygen supply device, the disinfection box, the flow control structure and the sealing box, the effects that the handle is stirred clockwise to automatically inject the disinfectant and the handle is rotated anticlockwise to automatically discharge the disinfectant are achieved, and through the cooperative use of the disinfection box, the flow contro
