Novel heat preservation cup

The invention discloses a novel heat preservation cup which comprises a cup body and a cup lid. The cup body is internally provided with a plurality of vacuum heat preservation layers. The cup lid is arranged on the cup body. The interior of the cup body is partitioned into a left cavity and a right cavity through a vacuum partition plate layer. The two side faces of the vacuum partition plate layer are provided with piece-shaped phase material heat exchangers in an attached mode. The cup body and the cup lid are sealed in a buckled mode. A through hole and a deformable connection rod are arranged at the positions, corresponding to the same cavity in the cup body, of the cup lid. An electric heater and a temperature sensor at the end of the deformable connection rod can be placed in the left cavity or the right cavity in a selective mode. By means of the novel heat preservation cup, the heat preservation effect can be improved, the harm, caused by tea volatilization, to human bodies is reduced, interval adjustment is achieved, the constant temperature and heat preservation functions are achieved, energy is saved, the environment is protected, and living at home and travel are facilitated.
