VACUUMIZING CUP LID, VACUUMIZING CUP, AND VACUUMIZING STIRRING/CRUSHING CUP

摘要

Disclosed are a vacuumizing cup lid, and a vacuumizing cup and a vacuumizing stirring/crushing cup having the vacuumizing cup lid. The vacuumizing cup lid (100) comprises an upper lid assembly (110) and a lower lid assembly (120), wherein the lower lid assembly (120) is provided with a connection part (123) hermetically connected to a mouth of a container, a vacuumizing cavity with a variable volume is provided between the upper lid assembly (110) and the lower lid assembly (120), and the volume of the vacuumizing cavity can be changed to zero; the vacuumizing cavity is provided with an air suction hole, wherein the air suction hole is used for sucking air from the container hermetically connected to the vacuumizing cup lid (100) into the vacuumizing cavity; and the vacuumizing cavity is provided with an air discharge hole, wherein the air discharge hole is used for discharging air from the vacuumizing cavity. The volume of the vacuumizing cavity of the vacuumizing cup lid of the present application is variable, the air in the vacuumizing cavity can be completely discharged from the vacuumizing cavity, and the air exhaust efficiency of the vacuumizing cup lid is improved.
