Abstract

一种防锁死水杯,属于容器,主要解决水杯杯盖音符亚导致难以打开的问题。其结构包括杯体和杯盖,所述的杯盖上设有一个圆孔,圆孔中设有一个塞子,所述的塞子通过转轴与杯盖活动连接。本实用新型采用在杯盖上设置泄压用圆孔的结构,能够在打开杯盖前向杯体内通入空气,消除负压,避免杯盖的锁死。

Description

一种防锁死水杯
技术领域
本实用新型涉及一种容器,具体地说是一种水杯。
背景技术
水杯是用来饮水的常用容器,当杯中存有热水时,由于杯内的热气受热膨胀,当盖好杯盖等待水杯中水冷却后,杯内的空气一并冷却收缩,形成负压,使杯盖难以打开。
实用新型内容
本实用新型的目的在于提供一种防锁死水杯,主要解决水杯杯盖音符亚导致难以打开的问题。
本实用新型解决其技术问题所采取的技术方案是:一种防锁死水杯,其结构包括杯体和杯盖,其特征是,所述的杯盖上设有一个圆孔,圆孔中设有一个塞子,所述的塞子通过转轴与杯盖活动连接。
本实用新型的有益效果是:采用在杯盖上设置泄压用圆孔的结构,能够在打开杯盖前向杯体内通入空气,消除负压,避免杯盖的锁死。
附图说明
图1为本实用新型的结构示意图(封闭状态)。
图2为图1的结构示意图(泄压状态)。
图中:1杯盖,2转轴,3塞子,4杯体,5圆孔。
具体实施方式
如图1、图2所示。一种防锁死水杯,其结构包括杯体4和杯盖1,所述的杯盖1上设有一个圆孔5,圆孔5中设有一个塞子3,所述的塞子3通过转轴2与杯盖1活动连接。
开杯盖1前,杯体4内的空气冷却收缩形成负压,施加给杯盖1一个强度为负压与杯盖面积之和的吸力,阻碍使用者顺利打开杯盖1,此时可将杯盖1上的塞子3从圆孔5中拔出,使气体进入杯体4内,消除负压,避免杯盖1的锁死,根据压强与压力关系换算:
F(压力)=P(压强)/S(作用面积)
因为塞子3面积较小,所以施加在塞子3上的吸力远小于施加在杯盖1上的吸力,因此拔出塞子3不费力。
