Three air outlets are opened at the top of the shell 11, and each air outlet is connected to the first cavity 12, the second cavity 13 and the third cavity 14 respectively. The first cavity 12, the second cavity 13 and the third cavity 14 are connected. Two connecting parts are provided in the shell 11, which are respectively located between the first cavity 12 and the second cavity 13 and between the second cavity 13 and the third cavity 14.

A weighted part is provided on the shell 11, and water is provided in the weighted part. The water in the weighted part can be squeezed into the three lifting balls 3 in turn through the weighted part, thereby increasing the mass of the three lifting balls 3 in turn, which can conveniently increase the patient's exhalation resistance.

[0019] like Figure 1As shown, the communicating portion includes two communicating cavities 21 opened in the shell 11, and the two communicating cavities 21 are respectively located between the first cavity 12 and the second cavity 13 and between the second cavity 13 and the third cavity 14. A first communicating hole 22 is opened on the left side of the two communicating cavities 21, and a second communicating hole 23 is opened on the right side of the two communicating cavities 21. When the lifting ball 3 is at the bottom, the second communicating hole 23 is located below the lifting ball 3. When the lifting ball 3 moves to the top, the first communicating hole 22 is located below the lifting ball 3. When air is blown into the first cavity 12, the exhaled gas will push the lifting ball 3 in the first cavity 12 to move upward. When the lifting ball 3 moves to the top of the first cavity 12, the gas will The gas enters the connecting cavity 21 through the first connecting hole 22, and then enters the second cavity 13 through the connecting cavity 21 and the second connecting hole 23. Then the gas will push the lifting ball 3 in the second cavity 13 to move upward. When the lifting ball 3 moves to the top of the second cavity 13, the gas will enter the connecting cavity 21 through the first connecting hole 22 again, and then enter the third cavity 14 through the connecting cavity 21 and the second connecting hole 23 again. Then the gas will push the lifting ball 3 in the third cavity 14 to move upward, so that the first cavity 12, the second cavity 13 and the third cavity 14 can be conveniently connected. The patient can blow the three lifting balls 3 upward in turn to achieve the purpose of exercise.

[0020] like Figure 1 As shown, the weight-increasing portion includes a water tank 41 fixedly connected to the housing 11, and water is stored in the water tank 41. A first piston 42 is slidably connected to the water tank 41. The first piston 42 moves upward to squeeze the water in the water tank 41, so that the water in the water tank 41 flows to the lifting ball 3. A push rod 43 is fixedly connected to the bottom surface of the first piston 42, and the bottom end of the push rod 43 extends to the outside of the water tank 41. By pushing the push rod 43, the first piston 42 can squeeze the water in the water tank 41. A diverter is provided on the housing 11, and the water in the water tank 41 can flow into the three lifting balls 3 respectively through the diverter, thereby increasing the weight of the lifting balls 3, and then it is possible to conveniently increase the patient's exhalation resistance and improve the patient's exercise intensity.

[0021] The diversion part includes a diversion pipe 45 arranged above the shell 11. The bottom surface of the diversion pipe 45 is connected to the first cavity 12, the second cavity 13 and the third cavity 14 respectively through three connecting pipes. A second piston 46 is slidably connected in the diversion pipe 45. A moving pipe 47 is fixedly connected in the second piston 46, and the end of the moving pipe 47 away from the second piston 46 extends to the outside of the diversion pipe 45. The top of the water tank 41 is fixedly connected to the end of the moving pipe 47 located outside the diversion pipe 45 through the connecting hose 44. When the first piston 42 squeezes the water in the water tank 41, the water will enter the moving pipe 47 through the connecting hose 44, and then By moving the position of the second piston 46, when the second piston 46 is located between the first cavity 12 and the second cavity 13, water will flow into the lifting ball 3 in the first cavity 12 through the moving tube 47; when the second piston 46 moves between the second cavity 13 and the third cavity 14, water will flow into the lifting ball 3 in the second cavity 13 through the moving tube 47; when the second piston 46 moves to the side of the third cavity 14 away from the second cavity 13, water will flow into the lifting ball 3 in the third cavity 14 through the moving tube 47, thereby conveniently diverting water to each lifting ball 3, thereby facilitating weighting of the lifting ball 3.

[0022] Working principle: First, the patient blows air into the first cavity 12 through the air inlet 5. The exhaled gas will push the lifting ball 3 in the first cavity 12 to move upward. When the lifting ball 3 moves to the top of the first cavity 12, the gas will enter the second cavity 13 through the connecting part, and then the gas will push the lifting ball 3 in the second cavity 13 to move upward. When the lifting ball 3 moves to the top of the second cavity 13, the gas will enter the third cavity 14 through the connecting part again, and then the gas will push the lifting ball 3 in the third cavity 14 to move upward. The patient can blow the three lifting balls 3 upward in turn, thereby achieving the purpose of exercise, squeezing the water in the weight-increasing part into the lifting ball 3, which can increase the mass of the lifting ball 3. When the mass of the lifting ball 3 increases, the patient needs to exhale with greater force, thereby effectively improving the patient's exercise intensity, so that the patient can exercise more conveniently.
