AI Technical Summary

Technical Problem

When used in high-temperature liquids, existing container covers are prone to water spray due to inconsistent internal and external air pressures, and cannot be effectively sealed, which may cause safety accidents and water leakage.

Method used

A container cover with a instant exhaust structure is designed, including a first cover body and a second cover body. A soft and elastic exhaust pipe and a first collision structure are provided on the first cover body. When the second cover body is closed or opened, the second collision structure pushes the first collision structure, causing the exhaust pipe to deform, and instantly discharge gas in the container to balance the internal and external air pressure.

Benefits of technology

Through the instant exhaust structure, the problem of high-temperature liquid being sprayed due to unbalanced air pressure is avoided, the sealing of the container cover is ensured, water leakage is prevented, and the insulation effect is improved.

Abstract

The utility model relates to a container cover with an instant exhaust structure, which is used for covering a container body and comprises a first cover body which covers the container body and comprises an exhaust pipe which protrudes out of the first cover body, is made of soft and elastic materials and is communicated with two sides of the first cover body, and a first collision structure which is arranged on the outer side of the exhaust pipe; the second cover body covers the first cover body in an openable and closable manner and can cover the exhaust pipe, the second cover body comprises a second collision structure arranged on the inner side of the second cover body, and in the process that the second cover body is closed and covers the first cover body, or in the process that the second cover body is opened, the second collision structure pushes the first collision structure to enable the exhaust pipe to deform. According to the instant exhaust structure in the embodiment of the utility model, gas in the container can be exhausted instantly when the second cover body is closed or opened, so that the problem of liquid ejection caused by inconsistent internal and external air pressures of the container is avoided, and the sealing and heat preservation performance of the container is enhanced.
