Referring to fig. 3 and 4 together, in one embodiment, the revolution counter 4 includes a counter body 41, a dial 42, and a pointer 43. The counter body 41 is provided on the trainer body 1. The dial 42 is rotatably provided on the counter body 41. The dial 42 is provided with a first counting mark 421. The first count mark 421 is provided around the rotation axis of the dial 42. The pointer 43 is rotatably provided on the counter body 41, and the axis of rotation of the pointer 43 is collinear with the axis of rotation of the dial 42. One end of the pointer 43 points to a first count flag 421. The transmission 3 drivingly connects the first piston 21 with the pointer 43, and the transmission 3 drivingly connects the second piston 23 with the dial 42. The first piston 21 slides to connect the air inlet 111 and the air suction channel 113 once, so that the pointer 43 can rotate, and the number of readings of the pointer 43 pointing to the first counting mark 421 is increased by 1. The second piston 23 slides to make the blowing port 121 communicate with the blowing channel 123 once, so that the dial 42 can rotate, and the reading of the pointer 43 pointing to the first counting mark 421 is decreased by 1. Specifically, the rotation axis of the first ratchet 321 coincides with the rotation axis of the second ratchet 341, and the first ratchet 321 and the second ratchet 341 can rotate in the same direction. The first ratchet wheel 321 and the second ratchet wheel 341 rotate to drive the pointer 43 and the dial 42 to rotate in the same direction. The first count indicator 421 increases in the same direction as the direction in which the pointer 43 rotates. In one embodiment, the dial 42 is further provided with a second counting mark 422. The second count indicia 422 is disposed about the axis of rotation of the dial 42. The number increasing direction of the second counting mark 422 is opposite to the number increasing direction of the first counting mark 421, and the corresponding indexing angle of the second counting mark 422 on the dial 42 is equal to the corresponding indexing angle of the first counting mark 421 on the dial 42. The dial 42 is provided with a first counting mark 421 and a second counting mark 422 at the same time, the training device is used for performing blowing training and then performing suction training, the reading of the pointer 43 corresponding to the second counting mark 422 is increased first and then reduced and reset, and counting is performed; when the exercise is performed in the sequence of the inspiration exercise and the blowing exercise, the exercise is counted by the first counting mark 421. Thereby avoiding the limitation of the training sequence. The use is more convenient.
According to the lung rehabilitation breathing training device in the technical scheme, when breathing training is carried out, the first piston 21 slides towards the air suction port 111 under the combined action of the breathing negative pressure and the first elastic piece 22, the automatic driving rotary counter 4 is used for counting, the use convenience is greatly improved, the phenomenon that the training times are too many or not enough is avoided, and the training effect is guaranteed.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
