Adjustable auxiliary respiratory training blowpipe

The utility model discloses an adjustable auxiliary respiratory training blowpipe, and belongs to the technical field of respiratory training equipment. The telescopic air blowing pipe is formed by connecting a plurality of air blowing pipes end to end in a sleeved mode, the diameters of the air blowing pipes are gradually reduced, a near-end opening of the air blowing pipe on the outermost layer serves as an expiration opening, a far-end opening of the air blowing pipe on the innermost layer serves as an air outlet, and the air blowing pipes moving relatively form the telescopic air blowing pipe. When the adjustable auxiliary respiratory training blowpipe is used for respiratory training, the lip contraction degree and the force exerting degree do not need to be controlled through the lip, the expiration resistance can be provided through the size of the air outlet of the thinnest blowpipe, the requirement for a user is low, and the adjustable auxiliary respiratory training blowpipe is suitable for respirato
