【技术实现步骤摘要】
结构改进的保温杯
本技术涉及杯子,特别涉及一种结构改进的保温杯。
技术介绍
保温杯可以方便的盛放饮用水,外出携带方便,在日常生活工作中使用非常广泛。保温杯由于具有良好的保温功能,在盛放开水后,使得开水的热气不会逸散出来,这也是延长杯子保温时间的很重要的设计,但是由于热气不会逸散出来,使得杯子内腔与外部环境之间的气压值存在较大差距,在打开杯子时,热气会凸出喷射出来,容易造成烫伤,使用很不安全。
技术实现思路
针对现有技术的不足之处,本技术提供一种结构改进的保温杯,它在打开杯子前可以排出保温杯中的热气,使用杯子更加安全。为达到上述之目的本技术提供的技术方案是:一种结构改进的保温杯,包括杯体和杯盖,所述杯体和杯盖装配相连,所述杯盖底面设有密封块,所述杯体开口内壁设有台阶,所述密封块卡装在台阶上,所述密封块底面设有一圈密封圈,所述台阶横部设有与密封圈适配的密封槽,所述杯盖顶面设有通槽,所述通槽贯通密封块底面,所述通槽中设有活动块,所述活动块顶部和底部侧壁均设有通孔,两通孔之间设有通道,所述通槽槽壁设有排气道,所述排气道贯通杯盖外壁,所述活动块底面设有限位盘,所述限位盘位于密封块底面。进一步地,所述密封块侧壁设有装配槽,所述装配槽开口向内翻边,所述装配槽中设有卡块,所述卡块伸出装配槽开口,所述卡块与装配槽槽底之间设有压簧,所述台阶竖部设有与卡块适配的卡槽,所述卡槽贯通杯体外壁。进一步地,所述通槽槽壁设有导槽,所述导槽位于排气道下方,所述活动块侧壁设有导块,所述导块伸进导槽顶部,所述导块底面与导槽底部槽壁之间设有弹簧,所述导块的活动距离与活动块顶部通孔到排气道之间的距离相等。 ...
