Description

Energy-storage type automatic closing cup cover

Technical Field

The utility model relates to a bowl cover of drinking cup, especially an energy storage formula self-closing bowl cover.

Background

The existing container for containing liquid, such as a water cup, is composed of a cup body and a cup cover connected to the cup opening of the cup body. Functionally, the bowl cover mainly has two kinds: one is a traditional cup cover and the other is an automatic cup cover. The traditional cup cover needs to be unscrewed from the cup mouth when drinking water, which is troublesome, and the suction nozzle can be automatically ejected by only pressing a button on the cup cover without unscrewing the cup cover when the automatic cup cover drinks water. Drinking water through a suction nozzle arranged on the cup cover. For example, patent No. ZL201821274383.1 discloses a flip-type nozzle cup cover, which includes: lid 1, top cap 2, 1 middle part of lid is equipped with delivery port 12, top cap 2 is installed in 1 upper end of lid through fixed pin 13, the bottom surface is provided with couple 14 under top cap 2, around having elasticity rubber band 15 on the couple 14, the elasticity rubber band 15 other end is walked around fixed pin 13 and is fixed inside lid 1, the bottom surface corresponds delivery port 12 position under top cap 2 and installs sealing plug 16, 1 one side of lid is equipped with according to keyway 17, 17 internally mounted has button 18 in the button groove, install reset spring 19 between button 18 and 17 medial surfaces in the button groove, button 18 upper portion is equipped with buckle 21, be equipped with the slot 20 that corresponds with buckle 21 on top cap 2.

Compared with the two modes, the two modes are more rapid and convenient, and are particularly suitable for children, old people and bedridden patients. However, in the nozzle cup with such a structure, the buckling structure of the buckle 21 and the groove 20 is often out of hook due to improper buckling or accidental touch of the button, which causes potential safety hazards such as water leakage and scalding.
