Description

气压咖啡过滤装置 技术领域
本发明涉及咖啡冲泡器具领域，尤其涉及一种气压咖啡过滤装置。
 背景技术
咖啡的制作十分讲究，水温、过滤速度、过滤压力等参数都会影响制作出的咖啡味道。其中，过滤压力对咖啡口感的影响尤为直接：当过滤压力较大时，过滤制作的咖啡口感较浓；当过滤压力较小时对应过滤制得的咖啡口感较淡。
目前制作咖啡的器具主要包括蒸汽锅式咖啡壶、水泵式压力咖啡壶、虹吸式咖啡壶、摩卡壶、滴漏式咖啡壶、法式滤压壶等，这些器具提供过滤制作咖啡。这些器具不仅结构较为复杂，且在制作咖啡时只能保持器具预设的冲泡压力而不能手动调节，或者手动调节过滤压力较为繁琐，不便于消费者操作使用。
当然，现有技术中也有使用各种简单的滤网来制作咖啡，但是，利用滤网制作咖啡，不仅受到滤网本身的结构条件限制，还需要凭经验控制流速、流量、搅拌程度、过滤时间等条件，制作优质咖啡并不容易，因其操作要求比较高导致难于推广使用。

 本发明的最佳实施方式
第一实施例
本发明提出一种结构简单且过滤压力可按需调节的气压咖啡过滤装置，方便用户快速制得口感佳的咖啡。如图1和图2所示，气压咖啡过滤装置具体包括过滤主体2、加压接口3、盖体4及气压发生装置7；过滤主体2包括过滤腔21、设在过滤腔21底部的咖啡出口211和位于咖啡出口211上方的滤网22，滤网22上设有若干过滤孔；盖体4盖合在过滤主体2上以将过滤腔21密封；加压接口3位于滤网22的上方，加压接口3的第一末端与过滤腔21相连通，且加压接口3的第二末端位于过滤主体2的外部，且气压发生装置7与加压接口3的第二末端相连通以增加过滤腔21内的压力。
其中，滤网22上的过滤孔的数量、单个过滤孔的孔径大小与咖啡粉的颗粒大小有关，确保将咖啡粉让在滤网22上再让过滤腔21内加入热水时，在无加压的环境下热水较难通过咖啡粉后从过滤孔滴落。
其中，在过滤腔21的底部设有台阶部26，滤网22可拆卸的设置在台阶部26上，便于使用完毕后取下滤网22进行清洗。
其中，过滤主体2的下末端设有裙边部24，便于将过滤主体2的下末端放置在咖啡壶1的壶口时，裙边部24与咖啡壶1的壶口抵接，使得过滤主体2可以更加平稳的放置在咖啡壶1的壶口，便于从咖啡出口211流出的冲泡咖啡直接流入咖啡壶1内，从而方便消费者户使用。
在一个实施例中，盖体4可以采用现有的任何其中一个密封连接方式与过滤主体2上末端可拆卸的密封相连。例如，过滤主体2上端与盖体4采用螺纹旋合相连。在过滤主体2上端的外侧面设有外螺纹25，而盖体4对应设有内螺纹，盖体4利用内螺纹与外螺纹25螺合相连以将过滤腔21密封，使得过滤腔21形成一个密闭空间，为利用气压发生装置7给过滤腔21增压来调节咖啡制作的环境提供了实现条件。
优选的，在盖体4与过滤主体2上末端之间还设有密封圈5，利用密封圈5能够提高盖体4与过滤主体2上末端之间的密封性能。
在本实施例中，加压接口3设置在过滤主体2上末端，从而加压接口3的第一末端位于过滤腔21的上末端。并且，加压接口3的第二末端与气压发生装置7之间还可以按需设置导气软管8（一般为软质胶管），让气压发生装置7利用导气软管8与加压接口3的第二末端相连通。通过导气软管8可以改变气压发生装置7与过滤主体2的相对距离以方便消费者操作使用。
气压发生装置7为手压气泵或电动气泵，在此不限。为了降低使用限制，本发明优选采用手压气泵71。其中，手压气泵71具有进气端及出气端，在进气端设有第一单向阀72，在出气端设有第二单向阀73；并且，第二单向阀73通过一个连接接头74与导气软管8相连通。
使用时，消费者手持手压气泵71后不断按压手压气泵71，过滤腔21内的压力是由消费者按压手压气泵71的力度与次数所决定的。一般情况下，通过按压手压气泵71可以让过滤腔21内轻松产生0.3巴(bar)左右的压强，以使利用本发明制得的咖啡质量超过现有的滴漏式咖啡壶制得的咖啡效果，可以达到现有的摩卡壶或蒸汽锅式压力咖啡壶的效果。因此，本发明虽然产生压力，但是压力不大，一般不大于0.3巴(bar)，从而使用安全可靠，并无压强过大的使用安全隐患。
在一个优选实施例中，还包括用于将咖啡粉末压置在滤网22上的隔网61（通常由不锈钢材料制成），隔网61上设有若干过水通孔。另外，在隔网61上设有提手62，通过提手62方便用户将隔网61从过滤腔21取放操作。通过隔网61将过滤腔21分隔成两部分：在隔网61与滤网22之间形成放置咖啡粉的咖啡放置空间，在隔网61上方为加水及用于对水进行加压的空间。设置隔网61的目的在于：隔网61将咖啡粉压置在隔网61与滤网22之间的咖啡放置空间内，可以防止在加水的时侯水将咖啡粉冲散而导致咖啡粉浮起，这样有利于提高咖啡的浓度和品质。
使用时，先将滤网22放置在过滤腔21底部的台阶部26，取适量咖啡粉放置在滤网22上，再手持提手62将隔网61放入过滤腔21内，使隔网61压在咖啡粉上；然后，往过滤腔21倒入适量的热水或开水，此时，由于滤网22上的过滤孔尺寸较小，倒入过滤腔21的热水，仅有非常少量会从滤网22上的过滤孔流到下部的咖啡杯1中，大部分热水会被咖啡粉阻止而留在过滤腔21内不会自动流到下部的咖啡杯1中；再旋紧盖体4将过滤腔21密封，手持手压气泵71后不断按压，通过手压气泵71往过滤腔21内压入空气以增加过滤腔21内热水的压强，促使热水快速流过咖啡粉，经滤网22上的过滤孔过滤后流到下部的咖啡杯1中。
由此可见，本发明的整体结构简单，实现成本低，通过外接的气压发生装置7让消费者可按需调节过滤腔21内的压力，从而调节热水流过咖啡粉的速度，达到调节过滤速度的作用，让热水快速流过咖啡粉时发生萃取，从而过滤制得口感佳的咖啡，操作简单且使用方便。
第二实施例
见图3所示，本实施例主要是体现：还可以将加压接口3设置在盖体4上，以方便使用。
第三实施例
上述第一、第二实施例中，所述气压发生装置7设置在盖体4的外部或者过滤主体2的外部，使得气压发生装置7可以按需拆卸或更换。
如图4所示的第三实施例，则将气压发生装置7内置在所述盖体4的内部。这种结构的好处在于：让气压咖啡过滤装置的整体外形尺寸较小，便于携带及收纳使用；同时也可以防止气压发生装置7发生遗失。
具体来说，所述盖体4包括内盖41和与所述内盖41盖合相连的外盖42，所述内盖42与所述外盖42之间具有容纳腔43；所述加压接口3设在所述内盖41上，所述气压发生装置7位于所述容纳腔43内。所述气压发生装置7可以在所述外盖42上设有进气口44，所述气压发生装置7连通设置在所述加压接口3与所述进气口44之间。其中，气压发生装置7优选采用现有的任何其中一种机械气泵或电动气泵。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
