本发明涉及一种高压咖啡机密封机构。
背景技术
现有的高压咖啡机能够用于萃取冲泡咖啡包及咖啡胶囊，其之密封机构包括下本体和上盖，所述下本体和上盖枢接在一起。所述下本体之上设有一开口朝上的咖啡盒，所述上盖之下设有一密封件，所述密封件和咖啡盒开口相使配合。所述下本体和上盖之间设有卡扣机构。由于上盖和下本体之间只设卡扣机构，密封件和咖啡盒之间的密封力全由卡扣机构承担，因此密封性能不佳，高压萃取过程中的震动会损害密封性能。
发明内容
本发明提供了一种高压咖啡机密封机构，其克服了背景技术中密封机构所存在的不足。
本发明解决其技术问题的所采用的技术方案是：
一种高压咖啡机密封机构，它包括一上盖（100）、一旋转盖（200）和一下本体（300），所述上盖（100）后端、旋转盖（200）后端和下本体（300）后端枢接在一起，所述下本体（300）设有一开口朝上的咖啡盒（310），所述旋转盖（200）之下设有一能适配盖接咖啡盒（310）开口的密封件（210）；
所述上盖（100）和下本体（300）之间设有卡钩机构；
所述上盖（100）和旋转盖（200）之间设有压紧机构，它包括把手（120）、压紧件（130）和开闭杆（140），所述把手（120）活动连接上盖（100），所述压紧件（130）和把手（120）之间构成连动连接关系且顶抵在旋转盖（200）之上，所述开闭杆（140）和把手（120）之间构成连动连接关系且适配卡钩机构。
一较佳实施例之中：所述把手（120）枢接在上盖（100），所述压紧件(130)为凸轮，所述凸轮和把手（120）之间构成同步同轴转动连接关系，所述凸轮外周面顶抵在旋转盖（200）之上。
一较佳实施例之中：所述开闭杆（140）把手（120）之间构成同步同轴转动连接关系。
一较佳实施例之中：所述卡钩机构包括卡钩（110）和卡槽（320），所述卡钩（110）枢接在上盖（100）且和开闭杆（140）相配合，所述卡槽（320）设在下本体（300）之侧。
一较佳实施例之中：所述开闭杆（140）和上盖（100）之间设有开闭扭簧。
一较佳实施例之中：所述下本体（300）之左右二侧都设有卡槽（320）；所述上盖（100）之左右二侧都枢接有卡钩（110）。
一较佳实施例之中：所述把手（120）枢接在上盖（100），且其枢接轴线位于第一平面上，所述第一平面为垂直密封件（210）且穿过密封件（210）中心的平面。
一较佳实施例之中：所述上盖（100）前端向下延伸成固接部（150），所述固接部（150）下端向前延伸成定位部（160）；所述旋转盖（200）前端设在上盖（100）和定位部（160）之间，所述旋转盖（200）之前端厚度小于上盖（100）和定位部（160）之间的间距，而且，所述旋转盖（200）和定位部（160）之间设有压簧（220）。
一较佳实施例之中：所述下本体（300）和旋转盖（200）之间设有弹开扭簧。
本技术方案与背景技术相比，它具有如下优点：
1.下本体、旋转盖和上盖之间设卡钩机构和压紧机构，则咖啡盒和密封件之间的密封力大，密封性能佳，操作省力、方便、简单；
2.把手枢接轴线位于垂直密封件且穿过密封件中心的平面上，则把手完全扣下时与旋转盖成垂直状态，也就是说在萃取时与咖啡包或者咖啡胶囊所产生的压力承同一方向，从而卡死旋转盖，使其在萃取时不会弹开，保证密闭的效果；
3.凸轮和把手构成同步同轴转动连接关系，通过凸轮配合旋转盖，则结构简单；
4.开闭杆（140）把手（120）之间构成同步同轴转动连接关系，则结构简单。

具体实施方式
请查阅图1至图8，一种高压咖啡机密封机构，它包括一上盖100、一旋转盖200和一下本体300，所述上盖100后端、旋转盖200后端和下本体300后端通过后枢轴400枢接在一起，而且，所述下本体300和旋转盖200之间设有弹开扭簧500。
所述下本体300的前中部设有一开口朝上的咖啡盒310，所述咖啡盒310之内设有萃取滤网330。
本实施例之中，所述旋转盖200的前中部的底面凹设有一凹槽，所述凹槽处嵌设有一固定架230，所述固定架230底面设有一能适配盖接咖啡盒310开口的密封件210。
所述上盖100前端向下延伸成固接部150，所述固接部150下端向前延伸成定位部160；所述旋转盖200前端设在上盖100和定位部160之间，而且，所述旋转盖200之前端厚度小于上盖100和定位部160之间的间距，使得所述旋转盖200前端能相对上盖100转动，而且，所述旋转盖200和定位部160之间设有压簧220。
所述上盖100和下本体300之间设有二卡钩机构。所述卡钩机构包括卡钩110和卡槽320，所述二卡槽320设在下本体300之左右二侧，所述二卡钩110通过卡钩轴190枢接在上盖100之左右二侧，并通过卡接件191定位。
所述上盖100和旋转盖200之间设有压紧机构，它包括一把手120、一压紧件130和二开闭杆140。
所述把手120枢接在上盖100前部之上。所述压紧件130为凸轮，所述凸轮和把手120之间构成同步同轴转动连接关系，所述凸轮外周面顶抵在旋转盖200之上，并对应位于固定架230之上。从而使得，所述把手120相对上盖100转动时，能带动凸轮转动，能够顶抵旋转盖200使其向下转动，使密封件210紧压在咖啡盒310之上，或者，旋转盖200能受压簧220顶抵向上转动，以松释密封件210和咖啡盒310之间的压紧。最好，所述把手120的枢接轴线位于第一平面上，所述第一平面为垂直密封件210且穿过密封件210圆心的平面。
所述二开闭杆140分别连接在把手120之左右二侧，而且，所述开闭杆140和把手120之间构成同步同轴转动连接关系。所述二开闭杆140分别配合二卡钩110，也即是能够分别顶抵卡钩110使其反转以松释卡钩110和卡槽320之间卡钩结构，也即是所述开闭杆140和把手120之间构成连动连接关系且适配卡钩机构。最好，所述开闭杆140和上盖100之间设有开闭扭簧170。
本实施例之中，所述凸轮固接在把手，所述把手固接把手轴180并通过把手轴180枢接在上盖，而且，所述开闭杆能同轴同步转动地套接在把手轴180。
为了使审查员进一步了解本具体实施例方式，下面描述密封机构的合上步骤：
1.对上盖100施加向下压力，克服弹开扭簧500弹力，使上盖100向下转动，使卡钩110固接在卡槽320之上，此时所述密封件210位于咖啡盒310之上，但密封件210还未与咖啡盒310接触，所以也没有因压缩量而产生手感紧的问题，请查阅图5；
2.压下把手120，凸轮320压下旋转盖200，克服压簧220弹力，使旋转盖200向下转动，使密封件与咖啡盒达到完全密闭，请查阅图6、7、8。
为了使审查员进一步了解本具体实施例方式，下面描述密封机构的打开步骤：
1.打开时向上拉开把手120，把手120的凸轮会先放开旋转盖，在压簧作用下解除密封件压缩量，从而减小因压缩量对卡钩与下本体所产生的摩擦力；
2、再向上拉起把手120，固定在把手120两侧的开闭杆会向下推动卡钩，使卡钩从下本体中退出，完成打开的动作。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
工业实用性
本发明一种高压咖啡机密封机构，其下本体、旋转盖和上盖之间设卡钩机构和压紧机构，因此咖啡盒和密封件之间的密封力大，密封性能佳，操作省力、方便、简单，具有良好的工业实用性。
