The movable bucket 24 drives the guide bucket 19 fixedly installed therewith to slide to the right during sliding to the right, and the movable rod 20 in the guide bucket 19 also synchronously moves to the right. Since the straight gears 9 at the two ends of the rotating shaft on the movable rod 20 move along the hypotenuse of the right triangle plate 7 from low to high, and move along the rack plate 8 on the hypotenuse during movement, the rotating shaft drives the movable rod 20 to move out of the guide bucket 19 upward during rotation. At this time, the distance between the second baffle 2001 on the movable rod 20 and the first baffle 1901 on the guide bucket 19 will be larger, and the reset spring 21 between them will be stretched at this time. Therefore, the child needs to overcome the force of the reset spring 21 during reset when sliding the movable bucket 24 to the right during blowing, so as to increase the intensity of the child during blowing.

The upper and lower ends of the sealing sliding block are connected by flexible baffles, so as to prevent the liquid from flowing out of the second rectangular through slot 2601. In the process of sliding upward, the sealing sliding block drives the piston disc 27 to start to slide upward, and in addition to the restoring force of the reset spring 21, the mass of the liquid above the piston disc 27 also needs to be overcome. In the process of lifting the piston disc 27 upward, the liquid above is squeezed into the lower horizontal pipe from the upper horizontal pipe of the u-shaped through pipe 6, and the liquid passing through the lower horizontal pipe enters the inner drum 26 again and is located at the bottom of the piston disc 27.

Figure 2 When the rotating shaft moves up and down along the hypotenuse of the right-angled triangle plate 7, the second connecting rods 10 on both sides begin to reciprocatingly deflect up and down, the two second connecting rods 10 respectively push the first sliding rods 4 on both sides to slide left and right in the reciprocating up-and-down deflection process, the two first connecting rods 4 respectively push the third connecting rods 5 on both sides to begin to deflect up and down in the left-and-right sliding process, and the two third connecting rods 5 simultaneously push the sliding cylinder 28 to begin to slide up and down along the vertical pipe of the u-shaped pipe 6 in the up-and-down deflection process. Figure 7 As shown in the figure, the sliding cylinder 28 drives the piston rod 14 on the outside to begin to slide up and down through the connecting shaft 2801 in the up-and-down sliding process. In order to ensure that the sliding track of the piston rod 14 is always vertically downward, the arc-shaped movable fixed plate 13 can preliminarily limit the piston rod 14, and secondly, the gas cylinder 15 and the bottom of the shell 1 are fixedly connected through a connecting piece, so that when the piston rod 14 moves up and down, it will reciprocatingly pump air into the gas cylinder 15. The principle of the gas cylinder 15 is the same as that of the common air pump for tires, which is a prior art and will not be described here. With the reciprocating movement of the piston rod 14, external gas enters the flexible air bag 16 through the gas cylinder 15 and is stored, so that the flexible air bag 16 is inflated. The first hose is installed with a second one-way valve to prevent the gas stored in the flexible air bag from leaking. When the training result needs to be evaluated, only the rotating valve 1701 and the first one-way valve need to be opened. The gas in the flexible air bag 16 will rush into the liquid barrel 17 and squeeze the liquid in the liquid barrel 17 into the measuring barrel 18 on one side. It should be noted that the water pressure in the liquid barrel 17 cannot open the first one-way valve without human intervention. Medical staff can determine the respiratory cycle per unit time by observing the height of the liquid in the measuring barrel 18.
