An intelligent respiratory training instrument disclosed by the present invention comprises an integrated box, a
breathing mask, an electrical stimulation patch and a box body, the inner wall of the
breathing mask is fixedly connected with an
oral cavity tube in a penetrating manner, the side wall of the box body is fixedly connected with an adjusting tube in a penetrating manner, the inner wall of the adjusting tube is rotatably connected with a spline shaft in a penetrating manner, and the side wall of the spline shaft is fixedly provided with an
impeller. An H-shaped plate is fixedly connected to the side wall of the top of the spline shaft, connecting rods are rotatably connected to the inner side walls of the two ends of the H-shaped plate, gravity balls are fixedly installed at the other ends of the connecting rods, a bottom plate is connected to the side wall of the spline shaft in a bonding mode, and pull rods are symmetrically and rotatably connected to the side wall of the bottom plate; the other end of each pull rod is rotationally connected with the adjacent connecting rod, and the bottom wall of the H-shaped plate is elastically connected with the bottom plate through a reset spring. By monitoring the intensity state of gas exhaled by a patient, the intensity state is fed back to the controller in the integrated box to automatically adjust training parameters, so that the optimal
training effect is achieved.
