【背景技术】
市面上较多的手动咖啡机，其一般包括外杯和内杯，内杯内设置一个挤压杆，将内杯内的咖啡挤压到外杯内，通过这种方式，直接是通过挤压液体，并不形成气压，通过这种方式挤压时的压力不好控制，获得的咖啡口感不好，且咖啡粉很容易被挤压到外杯内。
【发明内容】
本发明的目的是克服现有技术的不足，提供一种结构简单，操作方便，通过形成负气压冲出咖啡，手动压力式咖啡机。
为了解决上述问题，本发明采用以下技术方案：
一种手动压力式咖啡机，包括外杯体，所述的外杯体内设有一端开口的杯腔，所述的外杯体上设有能从开口端插入和拔出杯腔的内胆，其特征在于：所述的内胆内设有容装冲泡材料的内胆腔，所述的内胆上设有将杯腔分隔形成密闭空间的密封圈，所述的内胆腔底部设有与密闭空间内连通的过滤网，所述的内胆向外拔出时密闭空间内形成负压将内胆腔内的液体通过过滤网被吸入到密闭空间内。
如上所述的一种手动压力式咖啡机，其特征在于：所述的外杯体上设有能驱动所述的内胆向外拔出外杯体的驱动装置。
如上所述的一种手动压力式咖啡机，其特征在于：所述的内胆的外壁上设有外螺纹，所述的驱动装置为设在外杯体上并套在内胆外的环套，所述的环套内设有与外螺纹螺纹连接的内螺纹。
如上所述的一种手动压力式咖啡机，其特征在于：所述的内胆上端设有伸出外杯体的端头，所述的端头外径大于外杯体外径，所述的驱动装置设在端头和外杯体开口端之间。
如上所述的一种手动压力式咖啡机，其特征在于：所述的内胆上端开口，所述的内胆的开口端上设有盖子，所述的盖子与内胆之间设有防漏胶圈。
如上所述的一种手动压力式咖啡机，其特征在于：所述的内胆底壁上设有与杯腔连通的开口，所述的过滤网设在压靠在内胆底壁上将所述的开口遮盖。
如上所述的一种手动压力式咖啡机，其特征在于：所述的内胆底部外壁上设有环槽，所述的密封圈设在环槽内。
如上所述的一种手动压力式咖啡机，其特征在于：所述的外杯体底面设有防滑垫。
本发明的有益效果有：内胆内放咖啡材料，内胆往外拔出时，密闭空间增大，其内形成负压，将内胆腔的咖啡液体吸入到密闭空间内，拔出内胆后饮用杯腔内的咖啡，通过气压的方式冲泡咖啡，结构简单，操作方便；通过设置一个驱动装置，驱动内胆，操作更加的方便；底壁上设置开口，过滤网将开口遮盖并压靠在内胆底壁上，这样方便过滤网的拆洗。
【附图说明】
图1为本发明的立体图；
图2为本发明的剖视图；
图3为本发明的爆炸图。
【具体实施方式】
下面结合附图与具体实施方式对本发明作进一步详细描述：
如图1至图3所示，一种手动压力式咖啡机，包括外杯体1，外杯体1底面设有防滑垫10，外杯体1可以是保温杯，外杯体1内设有一端开口的杯腔11，外杯体1上设有能从开口端插入和拔出杯腔11的内胆2，内胆2的一端插入到杯腔11内，并能拔出来。内胆2上端开口，内胆2的开口端上设有盖子6，盖子6与内胆2之间设有防漏胶圈61，盖上盖子6后，整个咖啡机形成一个圆柱状杯体。内胆2内设有容装冲泡材料的内胆腔21，冲泡材料是水，咖啡，茶等，而咖啡的形式可以是咖啡粉、咖啡包、咖啡胶囊等。内胆2上设有将杯腔11分隔形成密闭空间12的密封圈4，内胆2插入到杯腔11内后，通过密封圈4将杯腔11隔开成上下空间，下部空间即为密闭空间12，内胆2底部外壁上设有环槽25，密封圈4设在环槽25内，密封圈4的作用相当于活塞环，内胆2可以相当于活塞杆，内胆2外拔时，密闭空间12的体积变大从而形成负压，密闭空间12指定是该空间没有较大开口。内胆腔21底部设有与密闭空间12内连通的过滤网3，过滤网3的网孔细小，可以让液体通过，而咖啡渣不能通过，当内胆腔21倒入水后，密闭空间12基本处于密闭状态。内胆2向外拔出时密闭空间12内形成负压使内胆腔21内的液体通过过滤网3被吸入到密闭空间12内，这样咖啡最终在外杯体1内。
内胆2可以通过手动拔出，当然这不是最佳的方式。最佳的方式为在外杯体1上设置能驱动内胆2向外拔出外杯体1的驱动装置5。具体来说，内胆2的外壁上设有外螺纹22，驱动装置5为设在外杯体1上并套在内胆2外的环套，环套内设有与外螺纹22螺纹连接的内螺纹51。内胆2上端设有伸出外杯体1的端头23，端头23外径大于外杯体1外径，驱动装置5设在端头23和外杯体1开口端之间，驱动装置5上端在端头23的下端，驱动装置5的下端支撑在和外杯体1开口端上。手动转动环套时，环套不上升，内胆2被带动向上，从而使密闭空间12增大，气压降低。内胆2底壁上设有与杯腔11连通的开口24，过滤网3设在压靠在内胆2底壁上将开口24遮盖，过滤网3通过过盈配合的方式挤压在内胆腔21侧壁，或者在过滤网3外套一个胶圈，通过胶圈挤压在内胆腔21侧壁，方便过滤网3取出清洗。
使用时，内胆2装入到外杯体1内，将咖啡倒入到内胆腔21内，然后向内胆腔21内冲入水，冲泡咖啡，然后转动环套，使内胆腔21向上移动，密闭空间12形成负压，内胆腔21内的咖啡液体被吸入到密闭空间12内，内胆2完全后，将外杯体1内的咖啡倒出，或者之间饮用，结构简单，操作方便，通过气压压出的咖啡泡沫丰富，口感好。
