[0024] The main structure includes an annular side wall 1, one end of the annular side wall 1 is an open end 2, and the side of the annular side wall 1 away from the open end 2 is a closed end 3. The closed end 3 is provided with a top plate cover 4 connected to the side wall, and the top plate cover 4 is located on the inner side of the annular side wall 1 and is provided with an elastic sealing ring 5. The elastic sealing ring 5 is provided with a sealing protrusion 6 on the side close to the annular side wall 1. The inner side of the top plate cover 4 is provided with a limit ring 7 on the outer side of the elastic sealing ring 5, and the inner wall of the annular side wall 1 is provided with an annular anti-slip protrusion 8;

[0025] By arranging an elastic sealing ring 5 on the inner side of the top plate cover 4, the elastic sealing ring 5 and the annular side wall 1 are used to clamp the barrel wall of the drinking water barrel, and then the outward expanded shape of the elastic sealing ring 5 is used to fit the inner wall of the drinking water barrel with the sealing protrusion 6 to form a fitting seal with a certain pressure, allowing the drinking water barrel and the barrel cover to shake within a certain range, thereby improving the sealing between the barrel cover structure and the drinking water barrel.

[0026] The elastic sealing ring 5 is arranged in a truncated cone shape, and the horizontal distance between the end of the elastic sealing ring 5 close to the top plate cover 4 and the annular side wall 1 is greater than the horizontal distance between the end of the elastic sealing ring 5 away from the top plate cover 4 and the annular side wall 1. By setting the shape of the elastic sealing ring 5, the side of the elastic sealing ring 5 away from the top plate cover 4 expands outward, and the sealing protrusion 6 is elastically fitted on the inner wall of the drinking bucket to achieve an extrusion contact seal.

[0027] An arc-shaped guide surface 9 is provided on the side of the sealing protrusion 6 close to the annular side wall 1, and a chamfer 10 is provided on the side of the limiting ring 7 away from the top plate cover 4 and close to the annular side wall 1. Through the arc-shaped guide surface 9 provided on the sealing protrusion 6, the port of the drinking bucket can be guided so that the drinking bucket is placed between the elastic sealing ring 5 and the annular side wall 1. Similarly, the chamfer 10 is provided on the limiting ring 7, which also plays a guiding role and guides the moving direction of the drinking bucket.

[0028] The center of the top plate cover 4 collapses toward the inner side of the annular side wall 1 to form a water outlet 11. A sealing plug 12 is clamped in the water outlet 11. A connecting piece 13 is provided on the surface of the sealing plug 12. The connecting piece 13 extends outward and is fixed on the top plate cover 4. The sealing plug 12 is connected to the top plate cover 4 through the connecting piece 13 to prevent the sealing plug 12 from detaching from the water outlet 11 and being lost.
