Abstract
The utility model discloses a vacuum cup which comprises a cup body and a cup cover. A single-way valve is arranged in the cup cover and is fixed at the top of the cup cover through a guide rod, and a through hole is formed at the top of the cup cover. The single-way valve is added at the position of the cup cover, so that air can enter, water cannot flow out, the same atmospheric pressure is maintained in the cup and outside the cup, the effect of the atmospheric pressure after water cooling is removed, the cup can be easily opened, and the insulation character is not lost. The vacuum cup is simple in structure, safe and sanitary.
