Technical Field

[0001] The utility model relates to the technical field of drinking utensils, and particularly relates to a straw cup cover with a splash-proof structure. Background Art

[0002] In the existing straw snap-on cup, when hot water is filled in the cup, due to the pressure difference inside and outside the cup, when the cup cover is opened, the hot water in the cup body is likely to splash out, posing a safety hazard during use.

[0003] Regarding the problem of hot water splashing, there are currently some straw snap-on cups with splash-proof structures. For example, exhaust holes are opened on the cup cover, and the exhaust holes are also opened when the flip cover is opened. Although it can achieve a certain splash-proof effect, the splash-proof effect is not ideal. The main reason is that its exhaust holes and the internal channel of the straw are almost opened synchronously, and there is still a risk of hot water splashing out through the straw, and the splash-proof effect is limited.
