It should be understood that the terms "a" and "an" as used herein in the context of "a first opening," "a second opening," and the like, are words of quantity, not of unit, and refer to one in the present application, and in other embodiments, may refer to a group, including one or more. In the present application, the "one surface of the air duct 200" refers to a side surface of the air duct 200, and when the air duct 200 is a circular (i.e., a cross-section of a circle) air duct 200, it is an outer circumferential surface of the air duct 200. Of course, in other embodiments, the "surface of the air duct 200" may also be the rear end surface of the air duct 200, and the air-vibration generating member 300 is disposed at the rear end surface to be matched with the air hole 220. In the present application, the one end side and the other end side are referred to as a rear end side and a front end side, respectively, and the following description is given of the rear end side and the front end side. In another embodiment, the one end side and the other end side may be referred to as a front end side and a rear end side, respectively, that is, the directions of the front end side and the rear end side are reversed. "out of surface" in the above description means out of the surface from the radial direction. Herein, the "top end" refers to an end radially outward, i.e., toward the casing 100, and the "bottom end" refers to an end radially inward, i.e., toward the center.
In this embodiment, the housing 100 has a hollow cylindrical shape. The casing 100 has an annular casing wall 110, and an end cap 120 formed at the rear end of the annular casing wall 110, the front end of the annular casing wall 110 extends forward and gradually converges to form the first opening 101, and the second opening 102 is formed in the end cap 120.

Preferably, the position of the second opening 102 is provided with an exhalation adjusting valve for adjusting the size of the convective air flow, so as to expand the application range, the applicable crowd and the universality of the breathing training device.
In this embodiment, preferably, the air passage 200 is a semicircular air passage 200 having a semicircular cross section and formed by enclosing a plane 201 and an arc surface 202, and the exhalation nozzle 210 is a circular exhalation nozzle 210 integrally formed at the front end of the semicircular air passage 200; in radial direction, circular breathing mouth 210's rear end surpasss semicircular part is an arc and connects face 211, arc is connected face 211 and is exhaled and is gone up with the mouth 210 and be corresponded to the part that the face 211 is connected to the arc forms transition connecting portion 212, the face 211 is connected to the arc makes breathing mouth 210 inner chamber to the gas flue 200 direction reduces gradually, thereby makes the process the face 211 department of connecting to the arc flows in the gas pressure grow in the gas flue 200. Furthermore, the arc surface 202 is a minor arc surface, that is, the cross section of the semicircular air passage 200 is a small semicircular air passage 200 below 1/2 of the cross section of the circular exhalation nozzle 210, so that the inner cavity of the air passage 200 is smaller, the air is stronger, and the insertion part 310 is more forcefully ejected out, under the resistance of the resistance part, the collision between the powerful air flow and the resistance part is more violent, the air vibration generation part 300 generates stronger swing, the breathing training effect is better, and under the condition that the air vibration generation part 300 generates up-down air vibration, the effect of synchronously vibrating the abdominal cavity of the user to discharge phlegm is better. It should be understood that the shape of the airway 200 is not limited to the semi-circular airway 200 described above. In other embodiments, in order to achieve the above-mentioned better training effect, as long as the cross-sectional area of the air passage 200 is smaller than that of the exhalation nozzle 210, a transition connection part 212 that converges toward the air passage 200 to communicate with the air passage 200 is formed at the rear end of the exhalation nozzle 210, and the transition connection part 212 gradually reduces the inner cavity of the exhalation nozzle 210 toward the air passage 200, so that the pressure of the gas flowing into the air passage 200 through the transition connection part 212 is increased. A third shelf 230 on which the front end of the swing portion 320 rests is erected on the surface of the air duct 200 (i.e., on the plane 201), the front end of the third shelf 230 is connected to the arc-shaped connecting surface 211, and the front end of the swing portion 320 rests on the third shelf 230 in the initial/reset state.
