     Water cups are one of the daily essential tools for people to drink water. Traditional water cups include plastic cups, thermos cups, space cups, etc. However, traditional water cups have a defect that cannot change the temperature of water. For example, in the hot summer, many people need to drink cold drinks in order to quench their thirst. Usually, ice cubes are added to drinks at room temperature to cool down, and ice cubes are usually directly frozen from tap water, and the hygienic effect cannot be guaranteed. In addition, the ice cubes will melt quickly in the drinks, which not only affects the taste of the drinks, but also cannot be used repeatedly. 
     For better understanding of the above technical solutions, the above technical solutions are described in detail below with reference to the accompanying drawings. 
     As shown in  FIG.  1   , the embodiment of the present application proposes a drinking cup, the drinking cup includes:

     In the technical solution adopted in this embodiment, in order to facilitate the replacement of the heat exchange substances in the temperature adjusting cavity, a mounting opening  41  is provided in the temperature regulating portion  40 . The mounting opening  41  communicates with the temperature adjusting cavity, and a detachable seal  42  is provided at the mounting opening  41 . After the seal  42  is removed, the mounting opening  41  is opened, and the heat exchange substances can be filled or replaced through the mounting opening  41 . After the seal  42  is installed, the mounting opening  41  can be closed to make the temperature adjusting cavity sealed. Then the heat exchange substances are sealed in the temperature adjusting cavity, and used to exchange heat with the liquid drinks in the water-holding cavity. The mounting opening  41  may be disposed on a side of the temperature regulating portion  40  facing the water-holding cavity  30 , or on a side of the temperature regulating portion  40  away from the water-holding cavity  30 . 
     Further, in an embodiment of the present application, the seal  42  is a sealing plug or a rotary cap. 
     In the technical solution adopted in this embodiment, in order to facilitate the detachable connection between the seal  42  and the mounting opening  41 , the seal  42  can be a sealing plug, and the sealing plug can be inserted into the mounting opening  41 . Through the interference connection between the sealing plug and the mounting opening  41 , the sealing of the mounting opening  41  is realized. The sealing plug can be a silicone plug or a rubber plug. A clamping groove can be provided on an outer peripheral surface of the silicone plug or rubber plug, and a clamping protrusion can be provided at the cup bottom  20  at the same time. When the silicone plug or rubber plug is installed in the mounting opening  41 , the clamping protrusion is clamped in the clamping groove, so that the reliability of the sealing connection between the silicone plug or the rubber plug and the mounting opening  41  can be improved. The seal  42  can also be a rotary cap, and a connecting pipe can be provided at the mounting opening  41 , and the connecting pipe and the rotary cap are connected through threads, so as to realize the detachable connection between the seal  42  and the mounting opening  41 . 
     Further, in an embodiment of the present application, the mounting opening  41  is arranged on the side of the cup bottom  20  away from the cup body  10 .
