Trachea sleeve oxygen breathing humidifying protecting device

The invention relates to a trachea sleeve oxygen breathing humidifying protecting device which comprises the components of a net-shaped housing, cylindrical sponge which is sleeved in the inner layerof the net-shaped housing, a cover which is mounted on the upper part of the net-shaped housing, and a trachea sleeve interface which is arranged at the middle part of the net-shaped housing. Two sides of the upper part of the net-shaped housing are respectively provided with an oxygen breathing pipe interface in which an oxygen breathing pipe is inserted and a humidifying pipe interface in whicha humidifying pipe is inserted symmetrically in a left-and-right direction. The oxygen breathing pipe interface and the humidifying pipe interface are respectively provided with a dustproof cover. Thenet-shaped housing is internally provided with a Y-shaped pipe. One end of the Y-shaped pipe is connected with the oxygen breathing pipe interface, and the other end is connected with the humidifyingpipe interface. A filtering
