Description

A kind of Exhaust screw

Affiliated technical field

The utility model relates to a kind of Exhaust screw, especially relates to the Exhaust screw that uses on a kind of teacup lid, belongs to the teacup technical field.

Background technique

At present, the teacup of known technology, in superior travelling teacup uses, often find after boiling water is poured teacup into, teacup lid screw wait for several hours after, because the boiled water temperature in the teacup descends, make the air pressure in the teacup, lower than ambient pressure, cause teacup lid to open, the utility model designer is being with this problem to carry out market survey to Yongkang, Zhejiang Province city China five metals city, before the utility model is not made, do not have the teacup that exhaust port is arranged and use, it is open that the patent searching document does not have technological scheme, when the utility model designer proposes that the teacup patent application of exhaust port is arranged, the Exhaust screw patent application on the teacup lid is proposed.

Summary of the invention

In order to overcome the deficiency of the Exhaust screw that uses on the no teacup lid in the prior art, the purpose of this utility model is the Exhaust screw that uses on a kind of teacup lid in order to provide, the teacup that this Exhaust screw can be matched in relief opening uses, there be being tightly connected of teacup lid of relief opening to connect by the supporting Exhaust screw of the utility model, when teacup lid can't be opened because of the water in the cup temperature drop is low, can open Exhaust screw, then the teacup lid smooth opening.

The technical scheme in the invention for solving the technical problem is: by screw body, handle, internal thread, the screw foundation ring is formed, it is characterized in that screw body top leaves handle, handle is the flat oval shape, be internal thread in the screw body, outside thread consistent size in the teacup of internal thread and exhaust port, during use teacup lid is covered on cup, after screwing supporting Exhaust screw is incorporated with on the outside thread of teacup lid central authorities of exhaust port, can open by the handle of Exhaust screw, negative pressure in the teacup is replaced as and the ambient air concora crush, reaches the purpose of opening teacup lid.

The utility model beneficial effect is a simplicity of design, and is with low cost, is easy to promote, and practicability is big.
