The invention provides a respiratory training instrument with a detection function. The respiratory training instrument with the detection function comprises: a base; and a
breathing structure which is arranged on the base, wherein the
breathing structure comprises a supporting seat, a worm rotating piece, a worm gear and a connecting piece. According to the
breathing training instrument with the detection function, the breathing structure is arranged and serves as a
breathing gas conduction structure during training of people, meanwhile, the structure has an angle adjusting function, during adjustment, only the worm rotating piece needs to be rotated, a breathing
pipe fitting has a certain rotating range, the flexibility of the breathing
pipe fitting during use is greatly improved, the fixed design of traditional breathing
pipe fittings is changed, adaptive adjustment can be carried out according to the use requirements of people, the flexibility of the respiratory training instrument in the use process is greatly improved, the personal use habits of different people are better met, people can always keep the most comfortable posture in the training process, and then long-time training can be kept.
