A heating cup comprises a cup body. A water inlet (42) and a water outlet (33) are arranged on the cup body. An isolated cavity is arranged in the cup body. An annular water channel is formed between the inner wall of the cup body and the isolated cavity and is not communicated with the isolated cavity. The water inlet (42) and the water outlet (33) are respectively communicated with the water channel. A heating unit (5) is arranged in the water channel. Because the isolated cavity is arranged in the cup body, the actual water storage capacity is reduced under the condition that the power is constant, and the water in the cup is always in the position close to the heating unit (5), so that the contact efficiency between the water and the heating unit (5) is improved and a faster temperature increasing speed is achieved. |
