A vacuum sealing water cup comprises a cup body (100) and a cup cover sealing component. The cup cover sealing component comprises a lower cup cover (200), an upper cover (300) and a reverse sealing cover (400). The lower cup cover (200) is rotarily sealed on the opening end of the cup body (100). A bulge of the upper surface of the lower cup cover (200) has a water mouth (210) ;the upper cup cover (300) hinged with the lower cup cover (200) is buckled on the lower cup cover (200) and an air sealing valve (500) is set at the opposite position of the upper cup cover (300) to the water mouth (210). A sealing ring (550) matched with the gas sealing valve (500) is set on the water mouth; the reverse sealing cover (400) hinged with the upper cup cover (300) is buckled on the upper cup cover (300). A cylindrical compression ring (440) is set inside of the reverse sealing cover (400). The cylindrical compression ring (440) interference press on the air sealing valve (500) when the reverse sealing cover (400) is buckled on the upper cup cover (300). The cup body is vacuumed with a vacuum device for a vacuum sealing state when the reverse sealing cover (400) is rotarily opened. When drinking is needed, it is only needed to open the reverse sealing cover (400) and slightly push the air sealing valve (500) to realize the discharging function, and then the upper cover (300) can be easily opened. The structure is simple and the operation is convenient. |
