Child respiratory tract cleaning and nursing device

A child respiratory tract cleaning and nursing device effectively solves the problems that an existing cleaning and nursing device is inconvenient to carry, and suction force is inconvenient to adjust. Comprising a left-and-right axial air cylinder, a piston capable of sliding left and right is coaxially arranged in the air cylinder, a negative pressure barrel with a rightward opening is coaxially arranged at the left end of the air cylinder, a left-and-right axial air outlet pipe located above the negative pressure barrel is arranged at the left end of the air cylinder, and a front-and-back axial collecting pipe is arranged at the front end of the negative pressure barrel. An adjusting column which is positioned on the left of the collecting tube and can shield the collecting tube is coaxially and slidably connected in the negative pressure cylinder, the left end of the adjusting column is coaxially and rotatably connected with a stud in threaded connection with the negative pressure cylinder, the front end
