Vacuum cup cover convenient to open

Abstract

The invention discloses a vacuum cup cover convenient to open. The vacuum cup cover comprises a cover body, and a mounting groove is formed in the side wall of one side of the cover body; a flip coveris rotationally connected into the mounting groove through a torsion rotating shaft; the flip cover and the cover body are closed in a buckling manner; a mounting cavity with an upward opening is formed in the side wall of the upper end of the flip cover; a power generation sheet, a silica gel layer and a metal sheet are sequentially arranged in the mounting cavity from top to bottom; the power generation sheet, the silica gel layer and the metal sheet are fixed in a bonding connection mode; the side wall of the upper end of the power generation sheet penetrates through the side wall of the mounting cavity and is exposed to the outside; a rubber plug is arranged in the flip cover, a transversely-arranged heat conduction piece is arranged on the side wall of the upper end of the rubber plug, the heat conduction piece is tightly attached to the side wall of the metal sheet, and a vent hole is formed in the side wall of the lower end of the rubber plug. According to the vacuum cup cover,the pressure intensity in the vacuum cup can be compensated, so that the vacuum cup cover is easy to open, and convenience is brought to the life of people.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a thermos cup lid that is easy to open. Background technique [0002] In winter, the weather is cold, and people invented the thermos cup in order to prevent the heat of hot water from losing quickly in the air. People who have used the thermos cup should know that the hot water in the thermos cup will gradually dissipate the internal heat as time goes by. When removing the cup cover, due to the effect of the pressure difference, it is difficult to open the cup cover smoothly, thereby bringing inconvenience to people's lives. [0003] For this reason, we propose a kind of thermos cup cover that is easy to open to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the problems existing in the prior art, and propose an easy-to-open thermos cup cover. [0005] In order to achieve the above object, the present inven...

AI Technical Summary

Problems solved by technology

People who have used the thermos cup should know that the hot water in the thermos cup will gradually dissipate the internal heat over time. Due to the principle of thermal expansion and contraction, the pressure in the cup will decrease, thus opening When the lid is closed, due to the pressure difference, it is difficult to open the lid smoothly, which brings inconvenience to people's life
