Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing stainless steel thermal insulation containers, and particularly to a novel inner plug cover structure of a labor-saving lever switch for a thermal insulation container. Background Art

[0002] In current stainless steel thermal insulation flasks, the design usually adopts a layout where water must pass through the inside of the plug when flowing out of the inner container. This layout aims to ensure excellent heat preservation performance. With frequent daily use and the passage of time, impurities such as water scale are likely to gradually accumulate inside the plug, which brings inconvenience to the cleaning inside the plug. This accumulation is not only difficult to remove but may also cause secondary pollution to the water quality. The conventional switch has a short force arm and is a laborious lever structure, and the opening requires extra switch components, which also increases the production cost.

[0003] Therefore, we need to redesign a novel inner plug cover structure of a labor-saving lever switch for a thermal insulation container. Through the labor-saving lever structure of the handle push-button switch, without extra switch parts, only one action of grasping and lifting can be used to operate the product, so that the water outlet process of the thermal insulation container no longer passes through the inside of the plug, effectively avoiding the accumulation of impurities such as water scale inside the plug, greatly improving the convenience of cleaning, and also effectively avoiding secondary pollution of the water quality.
