Vacuum cup capable of rapidly cooling

The utility model discloses a vacuum cup capable of cooling quickly, which comprises a cup body and a cup cover, a heat insulation layer and a cavity are arranged between the inner wall and the outer wall of the cup body, the heat insulation layer is arranged on the lower portion of the cup body, and heat conduction metal powder is arranged in the cavity. When the vacuum cup is placed uprightly, a heat insulation layer or a cavity is formed between the inner wall and the outer wall of the vacuum cup, heat conduction can be prevented, and the heat preservation function is achieved; when the vacuum cup is inverted, the heat-conducting metal powder is filled between the inner wall and the outer wall and is not blocked by the heat insulation layer, heat can be rapidly conducted outwards, and the rapid cooling function is achieved. 本实用新型公开了一种可快速降温的保温杯，包括：杯体和杯盖，所述杯体内壁与外壁之间设置有隔热层和空腔，所述隔热层设置于杯体下部，所述空腔中设置有导热金属粉。当保温杯正置时，保温杯内壁与外壁之间有隔热层或空腔，能够阻止热传导，实现保温的功能；当保温杯倒置时，导热金属粉填充到内壁与外壁之间，并且没有隔热层的阻挡，热量能够快速向外传导，实现快速降温的功能。
