Drinking cup

Abstract

The invention relates to a drinking device in order to solve a scalding problem in existing drinking devices due to the fact that water in cups is easily ejected out under high pressure. The provideddrinking cup includes a drinking cup body, a cup lid, a straw, a sliding cover, a movable piece and a spring. A first hole and a second hole are formed in the cup lid; the straw is inserted into an inner cavity of the cup body from the first hole; the cup lid extends along the brim of the second hole to form a cylindrical surrounding wall; the movable piece can upward penetrate through a via holedefined by the surrounding wall from the bottom of the surrounding wall; the spring is positioned in the surrounding wall and sleeves the periphery of a rod-shaped part, the lower end of the spring issupported at the lower end of the surrounding wall, the upper end of the spring faces upwards and elastically supports the rod-shaped part, an upward elastic force is applied to the movable piece with the surrounding wall as the basis, correspondingly the lower end face of the surrounding wall is upward pressed tightly by the bottom of a step of the movable piece under the action of the elastic force, and an opening in the lower end of the surrounding wall is sealed; the sliding cover is slidably connected to the cup lid. The drinking up has the advantages that venting is achieved by openingthe sliding cover and the drinking cup is safe and convenient to use.

Description

technical field [0001] The present invention relates to drinking utensils, in particular to drinking cups Background technique [0002] After the children's sippy water cup is filled with hot water with a high temperature, when the lid is screwed in, due to the unstable hot water and air flow in the bottle at this time, new water vapor will continue to be generated within a certain period of time, resulting in a temporary bottle. The air pressure inside the bottle is larger than that outside the bottle, and the function of the one-way air intake valve of the existing water cup of this type of water cup is not good. Air valve, causing hot water to spray from the straw, or steam from the intake valve, presenting a burn hazard. Or close the straw flip cover and put it in the bag after putting hot water into it, which will easily leak water and cause other items in the bag to get wet, which will bring trouble to the user. Contents of the invention [0003] The present invent...
