Technical Field
[0001] This utility model belongs to the field of cup lid technology, and specifically relates to a press-type sealing cup lid and a water cup. Background Technology
[0002] A water cup, also known as a glass, is called a "cup" in English. Water cups are typically containers for holding liquids, such as tea, water, and other beverages. Currently, most water cups use a sealing ring to connect the lid and the cup. The sealing ring fits over the lid, and when the lid and cup are closed, the sealing ring adheres to the inner wall of the cup, achieving a tight seal. However, if the cup contains hot water or a hot beverage, the high temperature increases the pressure inside the cup. When this pressure exceeds the friction between the sealing ring and the cup, the lid and cup may not seal properly. Utility Model Content

[0015] Compared with the prior art, this application has at least the following obvious advantages and effects:
[0016] This invention uses a button to control the up-and-down movement of a linkage component. When the linkage component moves upward, the sealing element protrudes outward and seals against the cup wall. When the linkage component moves downward, the sealing element is stretched and contracted, thus separating the sealing element from the cup wall and opening the cup lid. The button control is convenient, and the sealing effect is good due to the extension and retraction of the sealing element. It also prevents problems caused by pressure differences between the inside and outside of the cup, thus reducing the need for threaded designs on the cup lid.
[0017] This invention enables faster and more compact assembly of components by setting positioning and limiting points on each component, while the limiting and positioning points can control the range of motion of the components.
[0018] This invention uses a locking cover to lock the button, preventing it from being pressed when the cover is locked. Attached Figure Description

When the cup lid is closed, the sealing element 5 is in a compressed state, and the outer edge of the sealing element 5 protrudes outward and fits and seals against the inner wall of the cup body 8. When the button 2 is pressed, the lower end of the button 2 abuts against the movable buckle 73 of the limiting component 7, and the movable buckle 73 moves horizontally to both sides. At the same time, the limiting pin 75 moves out from the limiting hole 42 of the limiting shaft 41, and the linkage 4 moves down under the elastic force of the return spring 43. The compressed sealing element 5 on the linkage 4 is stretched, and the outer edge of the stretched sealing element 5 separates from the inner wall of the cup body 8, and the cup lid is opened.
