Description

咖啡机的液压驱动结构
技术领域
本发明属于咖啡机的技术领域，尤其涉及一种驱动咖啡机内活动机件移动的液压驱 动结构。 背景技术
咖啡机是一种制备咖啡饮料的机器， 咖啡机的传统部件包括有水罐、加热元件和水 泵等， 使用时将容置有咖啡粉的胶囊置于咖啡机内， 使用时， 再用驱动结构将咖啡机内 的两机件合拢形成萃取腔， 此时咖啡胶囊位于萃取腔内， 萃取时再将加热的水用水泵打 到萃取腔内， 水流过要萃取的咖啡原料， 咖啡饮料则从咖啡机的出水管流到杯子中。
现有饮料制备装置如咖啡机中驱动两机件移动以闭合和打开两个机件的驱动结构 主要有两种形式：
一种是手柄连杆驱动式，如一中国发明专利 CN1263415Y (专利号为 ZL00812101.X)
《一种为了制备饮料萃取物质的装置》， 披露了这样一种手柄连杆驱动式的机件驱动结 构， 其包括具有双臂的闭合杆和两个牵引杆， 闭合杆的两个臂固定在位于所述第二机件 的两侧的第一枢轴上并可绕其转动，牵引杆固定在位于第二机件的两侧的第二枢轴上并 可绕其转动， 牵引杆和闭合杆的两个臂的端部通过第三可转动枢轴牢固地固定在一起， 以便互相协同动作使装置闭合和打开。
手柄连杆式的机件驱动结构涉及部件多结构复杂，使用时，需向上扳动或下压把手， 在放置咖啡胶囊前， 把手向上扳动成一定角度， 把手翘起， 占据较大的高度， 这种咖啡 机需摆放在具有一定高度空间的位置上， 才能使用， 对咖啡机的安放空间要求高， 使用 不人性化。 另外现有手柄连杆式的机件驱动结构通过连杆结构实现两机件的锁紧， 为防 止萃取过程中漏水， 咖啡机对两机件有较高的锁紧力要求， 这样当两机件合拢后， 由于 两机件之间的锁紧力很大， 如要再次打开两机件， 需较大力才能扳动把手， 操作费力。
另一种是液压驱动式， 如一中国实用新型专利 CN201617680U (专利号为 ZL201020113007.1)《一种饮料酿造装置的送包脱包结构》， 披露了这样一种液压驱动式 驱动结构， 包括机座的后壁上固定有内固定座， 该内固定座上开有轴向贯穿的后进水通 道， 第二机件内具有后端开口的后腔室， 第二机件的后腔室活动套设在内固定座上并能 相对内固定座前后滑移，且内固定座的外周面与第二机件的后腔室内周壁之间为液密封 配合， 第二机件上还设有连通外界和所述第二机件上的凹腔的出液通道； 安装部的导向 孔内具有内肩胛， 各导向柱上还套设有复位弹簧， 该复位弹簧的一端抵靠在机座的前壁 上， 复位弹簧的另一端抵靠在所述导向孔内的内肩胛上， 所述第一机件上开有连通所述 酿造空间和外界的前进水通道。
液压驱动结构相当于手柄连杆驱动结构而言具有结构相对简单、锁紧力强、操作方 便、 空间占用少等优点。 在现有液压驱动结构中， 内固定座和第二机件的后腔室之间形 成活塞结构， 当高压冷水从后进水通道进入内固定座前端面和第二机件的后腔室之间形 成呈柱状的活塞腔，高压冷水需要充满整个活塞腔才能推动第二机件克服复位弹簧的弹 力前移， 由于活塞腔占据的空间较大， 高压冷水充满活塞腔所需时间长， 这势必会影响 咖啡机萃取咖啡的等候时间， 等候时间大约需要 40多秒， 工作效率低。 故现有液压驱 动结构还可作进一步改进。 发明内容
本发明所要解决的技术问题是针对上述现有技术现状而提供一种能快速驱动机件 前移的咖啡机的液压驱动结构。
本发明解决上述技术问题所采用的技术方案为： 一种咖啡机的液压驱动结构， 包括 机座；

设置在机座上、 能使机件保持后移趋势的复位弹簧；
固定在所述机座后部的固定座， 所述后腔室活动套设在固定座外周；
设置在固定座的外周面与后腔室的内周壁之间的第一密封圈；
其特征在于：
所述固定座的前端具有前凹腔， 所述机件的后腔室内固定有活塞件， 该活塞件后端 插入所述固定座的前凹腔内， 活塞件的外周面与前凹腔的内周壁设有第二密封圈， 所述 活塞件的外周面与后腔室的内周壁之间形成呈环状的压力腔，所述机件上开有与压力腔 相通的高压水流通道。
上述活塞件的后部具有凹腔， 所述后腔室的内顶壁上具有两凸起的连接柱， 连接柱 上开有螺纹孔， 所述活塞件的凹腔的外顶壁上具有两内凹部， 所述连接柱分别插设在各 内凹部中， 有螺钉穿过从凹腔的顶壁上穿过后与所述螺纹孔螺纹连接。 首先连接柱与内 凹部之间本身形成一个限位关系， 确保活塞件准确固定在机件的后部， 另外活塞件后部 的凹腔， 能方便采用螺钉将活塞件与机件固定。
上述活塞件的前部外周具有环形挡肩，所述环形挡肩与后腔室的内顶壁之间设有密 封垫， 在活塞件固定在所述后腔室内的状态下， 所述密封垫压紧在环形挡肩和后腔室的 内顶壁之间。 设置密封垫能使整个环形压力腔形成更好的密封， 防止高压水侧向渗透到 活塞件和后凹腔的内顶壁之间， 而使活塞件与机件连接不牢靠。
上述固定座的外周面上形成有第一环形安装槽，所述第一密封圈安装在该第一环形 安装槽内； 所述活塞件的外周面上形成有第二环形安装槽， 所述第二密封圈安装在该第 二环形安装槽内。 该结构使各密封圈均安装在部件的外周， 安装更方便。
上述压力腔的环形高度为 40〜60毫米， 最佳为 47.2毫米。 该高度范围内的环形压 力腔经多次试验证明， 其在能保证充足推力推动机件， 并使该移动机件与固定机件压紧 保持足够的锁紧力的基础上， 环状压力腔所占据空间最小， 能在较短时间内推动机件前 移并锁紧， 该液压驱动结构能降低咖啡机萃取咖啡的等候时间， 等候时间大约 10秒。
上述机座则包括前固定板、后固定板及支撑在前固定板和后固定板之间且左右平行 间隔设置的两根导向柱；所述导向柱活动穿过所述机件左右两侧使机件能相对机座前后 滑移； 所述复位弹簧有两根， 分别套设在导向柱上， 复位弹簧支撑在前固定板和机件之 间； 所述固定座固定在后固定板上。 该机架结构简单合理
与现有技术相比， 本发明的优点在于： 本液压驱动结构中的压力腔呈环状， 机件前 移相同距离， 环状压力腔内部空间和原有液压驱动结构中柱状的压力腔相比小很多， 故 高压水能更快速充满压力腔， 以推动机件前移， 减少咖啡机萃取咖啡的等候时间。 附图说明
