Although the existing vacuum cup can meet the heat preservation function of liquid contained in the vacuum cup, the water temperature cannot be quickly reduced due to the good heat preservation effect, and people cannot drink the vacuum cup smoothly. Therefore, the inventor designs a direct-drinking vacuum cup, wherein a cup sleeve is sleeved on a cup body of the vacuum cup, a cavity is formed between the cup body and the cup sleeve, and a lower water outlet hole communicated with the cavity is formed in the bottom of the cup body, so that water in the vacuum cup can flow into the cavity through the lower water outlet hole, the heat is dissipated by using the cup sleeve, and the direct-drinking vacuum cup can drink from a cup opening of the cup sleeve. Meanwhile, in order to avoid that water in the cup body flows out together when drinking water is discharged from the cup sleeve, a cup cover is arranged at a water filling port of the cup body in a matching way.

In order to enable water in the heat preservation cavity and water in the cavity between the cup body and the cup sleeve to be poured into the heat preservation cup from the same outlet, the inventor also designs a cup cover which can be simultaneously covered on the heat preservation cup and the cup sleeve, a bouncing switch valve matched with the heat preservation cup is arranged on the cup cover, and a hole communicated with the inner cavity of the cup sleeve is formed. However, once the user forgets to close the bounce switch valve, the beverage in the heat-exchange cup sleeve can directly flow out of the heat-preservation cavity to cause scald or frostbite when the user directly drinks the beverage.
