[0002] As an everyday necessity, water cups provide great convenience for people to replenish water in a timely manner. The design and materials of water cups have also been continuously improved with technological development. As living standards improve, people's demand for water cups is no longer limited to the basic function of holding water, but they are more demanding of ease of use and leak-proof performance.

[0003] In order to prevent the liquid in the cup from overflowing, a cover is generally provided on the mouth of the cup. The connection between the cover and the cup body is different, and the covering effect that can be achieved will also be different. The commonly used connection between the cover and the cup body is mostly connected by a threaded connection, and the cup cover needs to be unscrewed before drinking water, which is inconvenient to use. At the same time, the suction mouth of the existing straw cup cannot be disassembled, which has the defect of being difficult to clean. The anti-leakage function is not considered, resulting in the cup leaking easily when carrying or storing, causing inconvenience.

[0004] Therefore, how to provide a water cup with a nozzle cover that is easy to operate, convenient to use, and has a detachable nozzle for cleaning while also being leak-proof is a problem that technicians in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a water cup with a nozzle that can be detached for cleaning and a nozzle cover with a paddle to prevent leakage, aiming to solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
