Description

Technical Field

[0001] The utility model belongs to the technical field of water cup covers, and in particular relates to a dust-proof water cup cover that automatically opens. Background Art

[0002] At present, water cups are used in daily home and office occasions. It can be said that everyone has a water cup for daily use. The basic structure is a cup body plus a water cup cover, and the water cup cover is mainly a threaded cover or a direct snap cover. However, no matter which type of water cup cover, you need to take it off before you can drink water, and then cover it again, which is not very convenient. The water cups we usually use are basically more than 500mL, and the smaller ones are 300mL. The healthier and more scientific way to drink water is to drink a small amount of water multiple times, but generally the water is filled in the cup and drunk in multiple times, which leads to two problems. First, each time it is opened, it is troublesome and inconvenient. Second, every time it is opened, or opened and not covered, dust will fall in, polluting the water, resulting in unhygienic and unsafe drinking water.

[0003] CN106805665A discloses a cup cover and a water cup, which includes a cover body, a buckle, a pressing piece and at least one first elastic piece. A partition is fixedly arranged inside the cover body, and a plurality of through grooves are arranged on the outer periphery of the partition; a limiting groove is also arranged on the inner side wall of the cover body; the through grooves match the limiting grooves in number and are connected; the vertical end of the buckle is arranged through the through groove and is limited by the limiting groove; each first elastic piece is arranged between each buckle and the separator; the pressing piece is arranged on the side of the buckle away from the first elastic piece, and a boss is arranged on the side of the pressing piece close to the buckle, and the boss is arranged above each of the buckles. Although it can be operated with one hand, further operation is still required to open the water cup cover to pour water, which is still not easy enough. Utility Model Content
