Description

Technical Field

[0001] This utility model relates to the field of respiratory equipment technology, and more specifically, to a respiratory device for college students' sports training. Background Technology

[0002] In college sports training, the use of breathing equipment such as three-ball training devices for breathing training is very common. Chinese patent application number CN221788074U discloses a breathing training device. The device includes a base, with an inhalation cylinder fixed on one side and an exhalation cylinder fixed on the other side. The two are connected by a channel. An indicator ball is provided at the bottom of the inhalation cylinder, and a piston slide is provided in the exhalation cylinder. An outer interface is fixed to the outer side of the bottom end, and a bite is fixed to the top end. This solution achieves component connection through a hose: the inner interface of the hose is connected to the outer interface and rotated so that the inner interface is sleeved on the outer side of the outer interface, thereby firmly connecting the hose and the exhalation cylinder. Then, the bite is snapped on the outside of the installation port, which improves the ease of use.

[0003] However, in actual college student sports training scenarios, this device has obvious shortcomings. Due to the large number of trainees, if multiple people share the same mouthpiece, it is very easy to cause cross-infection. If the "one person, one mouthpiece" frequent changing mode is adopted, the mouthpiece and connecting tube will be repeatedly plugged and connected, which will cause the connection to loosen and leak air, thus affecting the breathing training effect. Therefore, this application proposes a breathing device for college student sports training, which aims to effectively solve the above problems. Utility Model Content
