[0029] Working principle: When the elderly are doing breathing training, they first use the bracket 103 to place the breathing tank 101 on the table (the bottom of the bracket 103 can be adsorbed on the table by setting a suction cup), and then connect the inhalation tube 3 and the exhalation tube 4 to the breathing mask 102. During the connection process (here, the connection of the inhalation tube 3 is used as an example), use two hands to hold the inhalation tube 3 and the connecting tube 1201 respectively, and then use your fingers to push the squeezing tube 1301 to slide on the side wall of the connecting tube 1201. In the process of pushing the squeezing tube 1301 to slide, the connection balls 120 will be released. 3, the fixed tube 1204 at one end of the inhalation tube 3 can be inserted into the connecting tube 1201, and then the push on the squeezing tube 1301 is released. Then, under the elastic action of the squeezing spring 1303, the squeezing tube 1301 pushes each connecting ball 1203, so that each connecting ball 1203 is squeezed into the annular connecting hole 1205 on the side wall of the fixed tube 1204. Then, under the squeezing action of each connecting ball 1203, the connection between the inhalation tube 3 and the breathing mask 102 is achieved. The exhalation tube 4 is connected to the breathing mask 102 according to the same operation method; After the inhalation tube 3 and the exhalation tube 4 are connected to the breathing mask 102, the breathing mask 102 can be worn on the user's face by using an elastic band, and breathing training can be performed. During the breathing training, when the elderly trainee inhales, the gas in the inhalation chamber inside the breathing tank 101 will be sucked into the chest cavity of the elderly trainee through the inhalation tube 3, and in the process of continuous inhalation, the circular plate 702 inside the inhalation chamber will be moved away from the hollow ring 2 under the action of air pressure. In the process of the circular plate 702 moving away from the hollow ring 2, the driving rod 601 will be driven to rotate by the interaction force between the supporting rod 704 and the spiral groove 705 on the side wall of the driving rod 601, and then the pointer 504 at one end of the detection rod 501 will be driven to rotate on the inhalation detection disk 502 under the meshing transmission action of the first bevel gear 602 and the second bevel gear 605. When the pointer 504 rotates to the required detection value, the inhalation can be stopped. After the inhalation is completed, when the exhalation training is performed, the gas is exhaled. At this time, under the unidirectional conduction effect of the second one-way valve of the connecting tube 1201, the exhaled gas will flow from the exhalation tube 4 into the exhalation cavity of the breathing tank 101. When the airflow enters the exhalation cavity, it will push the circular plate 702 away from the hollow ring 2 under the impetus of the airflow. At this time, the driving component 6 will drive the pointer 504 at one end of the detection rod 501 to rotate on the exhalation detection disk 503. When the pointer 504 rotates to the required detection value, the inhalation can be stopped. Therefore, through the setting of the detection mechanism 5, With the cooperation of the driving component 6 and the rotating component 7, the breathing training of the elderly trainee can be intuitively displayed through the detection dial, so that the elderly trainee can intuitively see the effect of the breathing training, and improve the elderly's ability to independently adjust the breathing rhythm and depth during breathing training, thereby reducing the risk of the elderly experiencing shortness of breath, chest tightness and other discomforts due to excessive exertion during breathing training, thereby improving the safety of breathing training for the elderly. At the same time, the design of a purely mechanical structure is used to realize the detection of breathing training, without the need for power supply, and lowering the threshold of use. It is especially suitable for elderly people with limited mobility or in remote areas.
