[0009] The one-way valve is arranged in the matching cavity, and the one-way hole in the one-way valve is used for keeping the cover outwardly and unidirectionally ventilating into the cup body. Therefore, when hot water is stored in the cup body, water vapor generated by the hot water cannot escape from the one-way hole, so that heat preservation of the hot water in the cup body is ensured. In order to release the hot gas water pressure generated in the cup body, a pressure relief groove which is in communication with the one-way hole is arranged on the upper end surface of the one-way valve. The pressure relief groove is matched with the guide head on the lower end surface of the pressure pipe piece. The pressure relief groove is internally provided with a protruding point which protrudes inwardly. When the pressure pipe piece is located above the pressure pipe cavity and seals the straw, at this time, the guide head is located above the through hole and abuts against the inlet of the pressure relief groove.

Since the straw must be opened by pushing the pressure pipe piece to open the cover, and the air pressure in the cup body is definitely released in the process of pushing the pressure pipe piece, the cup body with reduced internal air pressure will not cause the hot water to be pressed out of the straw, so that the situation of splashing hot water can be avoided, and forgetting to actively release pressure can also be avoided.

[0010] In order to avoid that the guide head cannot be aligned with the pressure relief groove in the process of the pressure pipe piece sliding, a guide seat is arranged in the matching cavity. A guide groove on the guide seat is in sequence with the pressure relief groove to form a groove body. Therefore, when the guide head slides in the guide groove in the guide seat, the guide head can be accurately aligned and enter the pressure relief groove. More preferably, an assembly groove can be arranged in the guide seat to assemble the one-way valve, so that the pressure relief groove and the guide groove form a continuous groove body.

[0011] Further, the pressure pipe cavity is internally provided with a pressure pipe plate. The straw is clamped by the pressure pipe piece and the pressure pipe plate in the process of being pressed into the pressure pipe cavity. The outer side wall of the straw towards the pressure pipe plate is provided with a crease part. The straw is bent along the direction of the crease part in the process of being pressed into the pressure pipe cavity. The upper end surface of the pressure pipe piece is provided with a buckling part.
