Description

Automatic closing lid based on energy storage

technical field

The present invention relates to a cup cover of a water cup, in particular to an automatic closing cup cover based on energy storage.

Background technique

The existing container for holding liquid, such as a water cup, is composed of a cup body and a cup lid connected to the cup mouth of the cup body. In terms of function, there are mainly two types of lids: one is a traditional lid, and the other is an automatic lid. The traditional cup cover needs to be unscrewed from the cup mouth when drinking water, which is troublesome. The automatic cup cover does not need to unscrew the cup cover when drinking water. Just press the button on the cup cover, and the suction nozzle will automatically pop up. Drink water through the spout set on the lid of the cup. For example, the patent No. ZL201821274383.1 discloses "a flip type suction cup cover", which includes: a cover body 1 and a top cover 2, the middle of the cover body 1 is provided with a water outlet 12, and the top cover 2 is installed by fixing pins 13. On the upper end of the cover body 1, the bottom surface of the top cover 2 is provided with a hook 14, an elastic rubber band 15 is wound around the hook 14, and the other end of the elastic rubber band 15 is fixed inside the cover body 1 around the fixing pin 13, and the lower bottom surface of the top cover 2 corresponds to the water outlet A sealing plug 16 is installed at position 12, a key slot 17 is arranged on one side of the cover 1, a key 18 is installed inside the key slot 17, a return spring 19 is installed between the key 18 and the inner side of the key slot 17, and the upper part of the key 18 is provided with a buckle 21. The top cover 2 is provided with a groove 20 corresponding to the buckle 21.

Comparing the two methods, the latter is faster and more convenient, especially suitable for children, the elderly and bedridden patients. However, with the spout cup of this structure, the clasp 21 and the groove 20 of the clasp structure often cause safety hazards such as water leakage and scalding because the clasp is not properly engaged or the button is accidentally pressed instead of being unhooked normally.
