[0044] In this embodiment: through the patient's breathing training, the exhalation process can drive the magnetic control component 202 to move through the magnetic control magnetic drive component 203, so that the magnetic drive component 203 cooperates with the rotating component 205 to realize the intermittent rotation of the filter component 204, so that each filter layer 2043 can switch its position, thereby ensuring the adsorption effect of the filter layer 2043 on water vapor, and the timed exhaust component 206 can push the sealing plug 2064 downward through the second spring 2065, so that the gas inside the circular shell 2061 can be pressed out, thereby achieving the purpose of pressurized exhaust, facilitating high-temperature disinfection of the filter layer 2043, and this process does not require additional equipment, so it can be achieved through a simplified mechanical structure, reducing energy consumption and reducing costs.

[0045] Working principle: When performing breathing training, the patient can perform breathing training through the air inlet hood 2014 and cooperate with the breathing training device 100, and exhale and inhale through the through hole 2025. When the patient exhales, the exhalation can drive the piston 2024 to move, and the piston 2024 can drive the elastic band 2023 to stretch, so that the piston 2024 drives the first magnetic ring 2026 to move, and the first magnetic ring 2026 drives the second magnetic ring 2034 and the movable ring 2031 to move through the magnetic force, and the movable ring 2031 drives the convex ball 2035 to move, so that the convex ball 2035 controls the roller body 2053 to rotate through the arc surface of the arc groove 2051. As the depth of the arc groove 2051 becomes shallower, the convex ball 2035 compresses the first spring 2036. When the convex ball 2035 enters the straight groove 2052 from the arc groove 2051, this When the patient is in the inhalation state, the elastic band 2023 drives the piston 2024 to reset, so that the first magnetic ring 2026 also drives the second magnetic ring 2034 and the movable ring 2031 to reset through magnetic force, so that the convex ball 2035 enters the right end of the arc groove 2051. Since the notch at the right end of the arc groove 2051 is deeper, the first spring 2036 drives the convex ball 2035 to reset, so that the convex ball 2035 smoothly contacts the arc groove 2051. When the patient is in the exhalation process, the convex ball 2035 can continue to drive the roller body 2053 to rotate, so that the roller body 2053 rotates intermittently, and the roller body 2053 drives the rotating shaft 2054 to rotate. The rotating shaft 2054 can drive the filter layer 2043 to rotate through the sealing ring 2041. The filter layer 2043 can rotate to switch positions, so that the switched filter layer 2043 can maintain a good water vapor adsorption operation.

[0046] Before the breathing training, the operating rod 2066 can be pulled up in advance according to the time requirement, so that the operating rod 2066 drives the sealing plug 2064 to move upward, so that the sealing plug 2064 drives the second spring 2065 to deform, so that the sealing plug 2064 takes in air through the first one-way valve 2063 and exhausts air upward through the second one-way valve 2069. When the sealing plug 2064 moves upward to a suitable position, the opening size of the air inlet pipe 2067 is adjusted by the valve 2068, so that the second spring 2065 can drive the sealing plug 2064 to reset. At this time, air is only taken in through the air inlet pipe 2067, so that the sealing plug 2064 moves slowly, and the heating wire 2062 can heat the inside of the circular shell 2061.

[0047] When the filter layer 2043 adsorbed with water vapor rotates to the position of the air outlet head 2072, the sealing plug 2064 presses the gas downward, and the air outlet pipe 2071 discharges the hot air to the air outlet head 2072, and discharges the hot air to the filter layer 2043 through the air outlet head 2072 for high-temperature disinfection and drying, so that the filter layer 2043 can perform a circulating filtering operation to meet the purpose of breathing training for patients.
