Description

一种电动真空茶叶罐 技术领域
本实用新型涉及一种储存和盛装茶叶的容器。
背景技术
目前用来储存和盛装茶叶的容器一般是铁皮筒、竹筒或瓷罐，但在我国南方地区，由于天气潮湿，很容易进潮气而霉变，所以有人将茶叶放在冰箱中以增加保鲜期，但在取出来时，低温的物体更容易凝集水分，进潮气在所难免，所以要想使茶叶长时间保鲜很困难，只好少买勤买。
发明内容
为了克服上述弊病，本实用新型提供一种电动真空茶叶罐，目的是增加茶叶的保质期，使人们可以长期饮用到新茶品质的茶水。
本实用新型的目的是这样实现的：将茶叶罐的盖子制成三层的，最上层是透明的，上边两层之间安装锂电池和带触摸开关以及单片机的印刷电路板、显示屏组件，下边两层之间安装电动真空泵、单向阀、真空开关、电磁放气阀，盖子和罐体之间使用硅胶垫密封。当触摸最上层触摸开关时，印刷电路板上的单片机控制电动真空泵转动，把罐内的空气通过单向阀抽出来，当罐内的真空度达到设计要求时，真空开关动作，通知单片机控制电动真空泵停止运转。此时由于大气压力，使罐子扣得很紧，加上罐体和盖子之间安装有硅胶垫，可保持长时间 不漏气，实现茶叶的真空储存。当需要取用茶叶时，可按动触摸开关2秒，印刷电路板上的单片机控制电磁放气阀将空气放入罐内，由于罐内真空度消失，就很容易打开了。取用茶叶后，扣上罐盖，按一下触摸开关，单片机控制电动真空泵转动，重复上述动作，罐内又恢复真空状态。
由于罐内体积较小，对真空度要求不太高(负压40KPa)，锂电池充满电可抽真空加放气一百多个循环，如果经常喝茶，每季度充一次电即可。
本实用新型请求保护的主要技术特征是：上支座上方固定连接有锂电池，显示屏，印刷电路板，上支座和下支座之间，固定连接有单向阀，电磁放气阀，真空泵，微型电动机，真空开关；真空泵与微型电动机同轴固定连接，一号硅胶管的一端与下支座上边的小管头贯通连接，另一端与真空开关进气口贯通连接，二号硅胶管的一端与下支座上边的小管头贯通连接，另一端与电磁放气阀出气口贯通连接，三号硅胶管的一端与下支座上边的小管头贯通连接，另一端与单向阀的进气口贯通连接，四号硅胶管的一端与单向阀的出气口贯通连接，另一端与真空泵的进气口贯通连接。
本实用新型请求保护的次要技术特征是：锂电池与印刷电路板电连接，电磁放气阀与印刷电路板电连接，微型电动机与印刷电路板电连接，显示屏与印刷电路板电连接，真空开关与印刷电路板电连接。
本实用新型的有益效果是：使茶叶的保质期比正常储存提高八至九倍，使用者可以长期饮用新茶品质的茶水了。
