When the plug 21 is subjected to external force to overcome the elastic force of the spring 3 and detach from the valve hole 45, the one-way valve is in an open state; when the external force decreases or disappears, the restoring force of the spring 3 drives the plug 21 to return to the valve hole 45, so that the one-way valve is closed, and the side of the valve body 1 is an open structure, so that the spring 3 is exposed to the external environment of the valve body 1. The one-way valve and one-way valve assembly of the utility model, because the side of the valve body 1 is an open structure, the spring 3 and the valve core 2 can be exposed to the external environment. When cleaning, there is no need to disassemble the one-way valve, and the one-way valve can be cleaned by flushing with water or using a brush to directly brush the spring 3 and the valve core 2.

[0030] In one embodiment, the valve body 1 and the valve seat 4 are formed into an integral structure, and the elastic member 3 and the valve core 2 are installed into the valve body 1 from the opening, which can reduce leakage points and places where dirt and grime accumulate, making the surface smoother and easier to clean.

[0035] like Figure 6 As shown, the valve seat 4 is a cylindrical structure, with a through hole arranged in the axial direction inside, and the inner wall of the through hole has a fourth convex ring 44 along its circumference, and the middle of the fourth convex ring 44 forms the valve hole 45. The outer wall of the valve seat 4 is provided with a circle of third convex rings 43 along the circumference, and the valve seat 4 forms a first sleeve part 41 on one side of the third convex ring 43, and the valve seat 4 forms a second sleeve part 42 on the other side of the third convex ring 43. The sleeve 11 of the valve body 1 is sleeved outside the first sleeve part 41 and fixedly connected to the first sleeve part 41. The connection method can be threaded connection, snap connection, twist connection, or other fixed connection methods, as long as it can be firmly connected, there is no limitation.

[0038] like Figure 7As shown, the plug 21 is sleeved with a sealing ring. When the one-way valve is in a closed state, the sealing ring contacts the edge of the valve hole 45 to seal the valve hole 45. In a preferred embodiment, the plug 21 includes a first convex ring 211 and a second convex ring 212 arranged along its circumference. The first convex ring 211 and the second convex ring 212 are coaxially arranged.
