An air inlet pipe is connected to one side of the breathing mask, and the breathing mask is connected to a cleaning mechanism through the air inlet pipe. One end of the cleaning mechanism is connected to a health training mechanism. The cleaning mechanism includes a tank body, a filter cartridge, a fixing plate, a disinfection sponge, water-absorbent and breathable cotton, a sealing gasket and a cover body. The health training structure includes an air outlet pipe, a connecting block, a connecting pipe, an exhaust port, a health training cylinder, a training ball, a slider, a connecting rod, a pointer and a scale plate.

[0004] The above-mentioned respiratory pulmonary function rehabilitation trainer has the effect of intuitively judging the strength of the patient's lung function, but it still cannot adjust the device pressure according to the patient's different rehabilitation stages, and has limitations in use. At the same time, the blowing mouth cannot be disassembled and cleaned. Long-term use can easily cause bacterial infection on the patient's lips. Therefore, it is necessary to provide a respiratory rehabilitation trainer. Utility Model Content

The end of the limiting guide rod 609 away from the connecting plate 603 slides through the cylinder body 1 and is fixedly connected to the limiting plate 610, and the end of the slide rod 613 away from the second piston 612 slides through the connecting cylinder 611 and is fixedly connected to the limiting block 614. An observation window 616 is provided on the connecting cylinder 611, and a scale 617 adapted to the second piston 612 is provided on the observation window 616.

[0025] Specifically, the screw 605 is rotated by the hand-tightening block 606, so that the connecting plate 603 can move under the action of the threads of the screw 605 and the screw sleeve 608, and the limiting guide rod 609 can limit and guide the connecting plate 603 when it moves. As the connecting plate 603 continues to move, the compression degree of the first spring 602 is changed, thereby changing the pressure on the first piston 601, thereby making the present respiratory rehabilitation trainer suitable for patients at different rehabilitation stages and improving the scope of application.

[0026] Embodiment 2

[0027] See also Figure 4 and Figure 5 On the basis of the first embodiment, it is further obtained that the disassembly mechanism 7 includes a connecting pipe 701, a fixing ring 705 is fixedly provided on the intake pipe 2, the connecting pipe 701 is sleeved with the fixing ring 705, a groove 702 is provided on the connecting pipe 701, a sealing ring 703 is fixedly provided in the groove 702, a sealing groove 704 is provided on the intake pipe 2 to be plugged with the sealing ring 703, an active cavity 706 is provided in the intake pipe 2, and a third spring 707 is fixedly provided in the active cavity 706, A sliding block 708 is fixedly provided at one end of the third spring 707, and a clamping rod 709 is fixedly provided on the sliding block 708. A clamping hole 710 adapted to the clamping rod 709 is opened on the connecting tube 701, and the clamping rod 709 slides through the movable cavity 706 and is clamped with the clamping hole 710; the connecting tube 701 is fixedly connected to the blowing nozzle 3, and there are four groups of clamping rods 709 and structures connected to the clamping rods 709. The four groups of clamping rods 709 are distributed on the intake pipe 2 with the axis of the intake pipe 2 as the center.

[0028] Specifically, the air blowing nozzle 3 is sleeved on the fixing ring 705 on the air intake pipe 2, and the sealing ring 703 is inserted into the sealing groove 704 to improve the sealing between the air intake pipe 2 and the connecting pipe 701. When the connecting pipe 701 is sleeved, the four clamping rods 709 will be squeezed and retracted into the movable cavity 706. When the connecting pipe 701 is completely docked with the air intake pipe 2, the clamping rod 709 will automatically pop out under the rebound action of the third spring 707 and be clamped with the clamping hole 710 on the connecting pipe 701, thereby completing the installation of the air blowing nozzle 3, thereby facilitating the replacement or cleaning of the air blowing nozzle 3.

[0029] In actual operation, the patient blows air into the cylinder 1 through the blowing nozzle 3. After the gas enters the cylinder 1, it presses and pushes the first piston 601, so that the first piston 601 moves laterally in the cylinder 1. When the first piston 601 moves, it squeezes the first spring 602. When the first piston 601 moves to the farthest point, the air inlet of the connecting cylinder 611 is opened, and the gas enters the connecting cylinder 611 and presses the second piston 612. The second piston 612 moves upward and squeezes the second spring 615 until the second piston 612 moves to the farthest point. At this time, the scale position corresponding to the second piston 612 can be observed through the observation window 616 to judge the patient's lung function recovery status;

[0030] When the pressure of the device needs to be adjusted according to the different rehabilitation stages of the patient, the screw rod 605 is rotated by the hand-tightening block 606, so that the connecting plate 603 can move under the action of the threads of the screw rod 605 and the screw sleeve 608, and the limiting guide rod 609 can limit and guide the connecting plate 603 when it moves. As the connecting plate 603 continues to move, the compression degree of the first spring 602 is changed, thereby changing the pressure on the first piston 601, so that the respiratory rehabilitation training device can be suitable for patients at different rehabilitation stages;

[0031] When the blowing nozzle 3 needs to be disassembled for cleaning or replacement, it is only necessary to press the four clamping rods 709 and retract them into the active cavity 706, and then pull the connecting pipe 701 out from the air intake pipe 2 to remove the blowing nozzle 3. After cleaning or replacing the blowing nozzle 3, the blowing nozzle 3 is sleeved on the fixing ring 705 on the air intake pipe 2, and the sealing ring 703 is then inserted into the sealing groove 704 to improve the sealing between the air intake pipe 2 and the connecting pipe 701. When the connecting pipe 701 is sleeved, the four clamping rods 709 will be squeezed and retracted into the active cavity 706. When the connecting pipe 701 is fully connected with the air intake pipe 2, the clamping rod 709 automatically pops out under the rebound action of the third spring 707 and is clamped with the clamping hole 710 on the connecting pipe 701, and the installation of the blowing nozzle 3 is completed.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
