[0012] Preferably, the surface of the suction end is further provided with a circumferential concave-convex texture.

[0013] Compared with the prior art, the degradable straw has the following beneficial effects:

[0014] 1. The degradable straw has increased structural strength of the inner wall of the straw through the arrangement of the inner film, so that the straw can maintain good shape stability and is not prone to deformation or collapse when a certain pressure is borne, such as when a user sucks a drink, and ensures that the drink can be smoothly sucked out through the straw, thereby improving the reliability of the straw in use.

[0015] 2. The degradable straw is limited in position through the clamping of the ring groove on the convex ring after the convex ring is inserted into the inside of the connecting groove during installation, thereby preventing the connecting pipe from falling off, and the connecting pipe can also rotate in the inside of the connecting groove, thereby facilitating use.

[0016] 3. The degradable straw is provided with the concave-convex texture, which can not only increase the friction force when the straw contacts the lips to prevent slipping, but also generate a certain vortex effect when the liquid passes through, so that the liquid flows more smoothly and improves the drinking experience.
