1. The utility model provides a stock solution device for breathing machine which characterized in that:

  • the liquid storage device comprises a shell assembly, wherein a cavity is formed in the shell assembly;

    a ventilation flow passage is communicated in the cavity;

    the ventilation flow channel is connected with a first detection air port and a second detection air port;

    wherein the vent flow passage is configured as a variable cross-section vent flow passage capable of creating a pressure differential between the first and second sensing ports;

    the ventilation flow channel is formed by a variable-section pipeline, a first opening and a second opening are formed in the cavity, and the variable-section pipeline penetrates into the cavity from the first opening to enable the first detection air port to be communicated with the cavity;

    the variable-section pipeline penetrates out of the second opening, so that the cavity is communicated with the second detection air port;

    the two ends of the variable-section pipeline are respectively provided with a first exposed pipeline part positioned outside the cavity and a second exposed pipeline part positioned outside the cavity, and the first detection air port and the second detection air port are respectively arranged on the first exposed pipeline part and the second exposed pipeline part.
