一种保温饭壸盖
本技术涉及一种保温饭壸盖,更具体地说,涉及一种不漏水、带有均压结构、易开盖的保温饭壸盖。
技术介绍
现代社会生活,难免需外出工作或上学,为顾及家人食物的营养和卫生,保温饭壸已成为不可短缺的生活必须品。而目前现有的保温饭壸,或多或少都存在漏水的现象,如果要使饭壶盖不漏水,又必须用力拧紧壶盖。但是饭壶中如果装有较高温度的食物,待食物冷却后即因热胀冷缩造成壶里产生负压,而打不开饭壸盖。
技术实现思路
鉴于以上情形,为了解决上述技术存在的问题,本技术提出一种保温饭壸盖,方便使用,能确保壸中的液体封锁在壸里而不外漏,并且不会产生负压而难开盖。一种保温饭壸盖,包括壸盖体及均压结构,所述的壸盖体是由塑料材料制成的边缘有螺纹的盖面、盖面里面用装有保温材料的不锈钢内盖经超声波焊接而成,该不锈钢凸边有一凹槽,不锈钢内盖面中间有一圆凹槽和圆孔,所述的壶盖里部内缘螺纹和不锈钢内盖间有一密封硅胶圈,该硅胶圈的内径固定在不锈钢内盖面板边的凹槽上,另一边紧贴盖面内边缘螺纹,硅胶圈平面上有凸出半圆弧型硅胶片,凸出半圆弧的边正好和保温壶的口部形成密封锁水状态,所述的均压结构是在壶盖中间向内延伸圆形凹槽,凹槽下端有一圆孔,圆孔周边有1-4个通气孔,通气孔的外端与固定在盖里的不锈钢内盖间有一防渗水硅胶,下端面与不锈钢内面板中间凹槽平,该圆孔正对不锈钢的圆孔,在从盖面凹槽上面套入有凸出按钮,按钮带有活扣,再从不锈钢内面板这端的中间孔插入连杆,连杆的顶端有一凹槽,下端有一固定圆片,圆片上有密封的硅胶正盖住不锈钢内盖中间凹槽里所有孔,连杆套弹簧和按钮活扣连接一起,在弹簧力作用下,连杆下端 ...
