Description

一种真空保鲜盒盖及保鲜盒 技术领域
本发明属于日用品技术领域，尤其是涉及一种真空保鲜盒盖及保鲜盒。
背景技术
随着生活水平的逐渐提高，人们对日常食物的保鲜也越来越重视，常规的保鲜盒已难以满足需求，市面上出现了真空保鲜盒盖，真空保鲜盒盖相较于常规的保鲜盒保鲜效果更佳，同时能延长食物的保质期，提高食物利用价值，因此备受人们的欢迎。
如专利号为ZL200910147616.0(CN101570260B)的中国发明专利《一种连泵真空保鲜盒盖》，其公开的技术方案包括盒体、盒盖、按手、固定活塞组件、滑动气缸组件等部分，按手、固定活塞组件和滑动气缸组件组成手按式真空泵，通过按手和滑动气缸组件上下移动，将盒体内的空气抽出，盒体内的负压逐渐增大并接近真空，实现真空保鲜的目的。
在该发明专利中，盒盖的中部设有凹腔，凹腔中间设有凹腔第二套筒，凹腔第二套筒上端设有环形卡扣，固定活塞中部设有第二套筒，紧靠活塞下方第二套筒外壁处设有鼓形凸环，盒盖与固定活塞在装配时，通过把固定活塞第二套筒插入盒盖第二套筒内腔，使固定活塞的鼓形凸环压入盒盖的环形卡扣中即可。可见，盒盖与固定活塞是通过压装进行装配到，而在抽真空时，滑动气缸组件在上下移动的过程中会与固定活塞发生碰撞，当碰撞力度较大时，有可能使鼓形凸环脱离 环形卡扣而散架，结构的稳定性较差，存在一定的隐患。
在该发明专利中，气门上设置有中孔台阶，硅胶垫上设置有倒扣第二套筒和多个气槽，当气门与硅胶垫装配在一起时，倒扣第二套筒穿过到中孔台阶内，此时气门的下端面与硅胶垫的上端面贴合。抽真空后，气门与硅胶垫受气压作用紧密贴合，在放气时，通过按手带动固定活塞顺时针同步旋转，左螺旋凸台将气门的螺旋两翼向上顶起，使气门的气门边与硅胶垫的内腔底面分离，空气从滑动气缸的底部气孔一进入，通过气缸工作室、固定活塞的气槽、气门的气门边与硅胶垫的内腔底面的分离间隙、硅胶垫的气孔一、盒盖的气孔一，快速进入储藏盒，达到放气目的。由于气门与硅胶垫是贴合的，为了确保在放气时硅胶垫的气孔一为打开状态，需要将气门大幅度的向上顶起，但硅胶垫为弹性材料制成，气门大幅度的向上移动有可能使倒扣第二套筒与中孔台阶分离，导致气门脱离硅胶垫，脱离后无法自行复原，可靠性较差。
在该发明专利中，滑动气缸组件既能左右旋转，又能垂直上下运动，滑动气缸组件通过环形扭簧实现左右方向复位，环形扭簧安装在过渡环的环槽内，安装时需要将滑动气缸的拨叉对准环形扭簧，当滑动气缸在环形扭簧的作用下旋转到释放位置时，滑动气缸解除上下方向上的限制，此时复位弹簧展开并使按手和滑动气缸同时向上弹起，方便按压。由于环形扭簧需要绕一圈，体积较大，不仅成本较高，占用空间大，并且稳定性也较差，不适于长久使用。
在该发明专利中，盒盖的中部设有凹腔，凹腔两侧分别设有键槽和凸扣，凹腔中间设有凹腔第二套筒，凹腔第二套筒上端设有环形卡扣，第二套筒内腔两侧分别设有左螺旋凸台和右螺旋凸台，第二套筒内腔底部设有气孔一，盒盖的外边内侧设有环形密封槽，密封槽内环设有密封圈拆卸口，可见，盒盖的结构复杂，不易制作加工，生产良率不高，且卫生死角较多，不便于后期清洗。

本发明设置单独的左弹性件和右弹性件，旋转滑动气缸后，通过左弹性件与左定位块配合使滑动气缸向左复位，或通过右弹性件与右定位块配合使滑动气缸向右复位，相对于环形扭簧，无需绕环槽一圈，体积较小、成本更低，且稳定性较好。
本发明将盒盖分解为盖体、第一套筒和卡扣组件，第一套筒通过卡扣组件可拆卸的设置在凹腔内，分解后的部件易于单独加工生产，然后通过简单的组装即可得到该盒盖，有利于提高生产良率，降低生产成本，同时分解后的部件卫生死角较少，便于后期清洗。
