Water cup elastic cover and water cup

Abstract

The invention discloses a water cup elastic cover and a water cup. The water cup elastic cover comprises a connecting body and a flip cover, and the flip cover comprises an outer cover and an inner cover; the flip cover is rotatably connected with the connecting body through an inner cover of the flip cover, a first torsional spring is arranged at the rotary joint between the inner cover and the connecting body, the outer cover is rotatably matched with the inner cover, and a second torsional spring used for driving the outer cover to reset after rotating relative to the inner cover is arranged at the central position between the outer cover and the inner cover; the outer cover and the connecting body are provided with clamping hooks which are matched with each other, and the clamping hooks can be separated from each other when the outer cover rotates to exceed a set angle relative to the inner cover and can be locked with each other after the outer cover resets relative to the inner cover. According to the water cup elastic cover, the flip cover is controlled to be opened in a rotating mode, a traditional switch button does not need to be arranged, and the water cup elastic coveris simple and reasonable in structure, easy to machine, manufacture and assemble, good in operation hand feeling and more reliable in using performance.

Description

technical field [0001] The invention relates to the technical field of drinking utensils, in particular to a water cup flip cover for a water cup. The present invention also relates to a water cup provided with the spring cover of the water cup. Background technique [0002] The general water cup flip cover is equipped with flip cover, connecting body, and switch button and other components. Since the switch button is set separately and assembled on the cup cover through pins, the button will protrude from the cup cover, resulting in an unintegrated appearance of the cup cover. , the structure is cumbersome, and it is not convenient for assembly and production. [0003] To this end, CN210158427U discloses a kind of rotating and bouncing cup cover, which includes a main body connected to the cup body, a spring cover, a drinking port, a screw cap and a cleaning cover. The side can be reversibly hinged by torsion springs and positioning pins. The bottom of the spring cover is...

AI Technical Summary

Problems solved by technology

[0004] Although this kind of rotating and bouncing cup cover is beautiful in appearance, easy to operate, and safer, it has many parts and its structure is too complicated. Moreover, because the rubber sleeve is used to drive the cup cover to rotate and reset, it is difficult to operate, whether it is the operating feel or the use performance. There are certain deficiencies in both. After long-term use, once the rubber sleeve ages and loses its elasticity, the cup lid cannot be reset automatically. It requires manual reset through redundant auxiliary actions, which greatly affects the user's experience.
