Description

适用于饮料机的自清洗式三通阀 技术领域
本实用新型涉及三通阀领域，特别涉及一种适用于饮料机的自清洗式三通阀。
背景技术
三通阀，指的是具有三个通道口的阀体，常被用于管路控制领域。常规的三通阀包括内置三路互通管道的三通阀体以及置于其内的阀芯，阀芯置于其内的一路管道内以实现三通管路和双通管路的切换。由于三通阀可被应用于切换通道管路，故其在很多机械设备内均有广泛的应用，然而目前常规的三通阀被应用于饮料机中时存在一些弊端。
以现调饮料机为例进行说明，现调饮料机内包括存放饮料原料的原料存放容器以及存放水的水存放容器，原料存放容器内的原料流出并和水以一定的比例混合配置得到现调饮料，为了实现该功能，原料存放容器和水存放容器之间需设置三通阀，将阀芯置于连接原料存放容器的管道内，通过控制三通阀的启闭来控制原料的流出。
然而，现调饮料机内存放的饮料原料分为很多种类，包括原料粉剂和/或原料液，当原料粉剂经过三通阀进入管路与水进行混合时，粉剂会残留在阀芯芯体上，长此以往，阀芯本身会滋生细菌，进而影响配置的饮料的质量，同时，阀芯内残留的粉剂也容易使得后续配置的饮料串味，影响饮料的风味，另外，堆积粉剂的阀芯也会使得阀芯的控制不方便，影响控制的精度。当原料液经过三通阀进入管路与水进行混合时，原料液内往往含有甜味剂或者其他调味剂， 这些甜味剂残留在阀芯本身也会造成以上问题。
考虑到现调饮料机常被用于公共场所且处于无人运营的状态，经常地对现调饮料机进行拆卸以清洗其内的三通阀会很大程度地增加运营成本，且拆卸更换清洗也耗时耗力，也在无形中增加了现调饮料机的运营成本。
实用新型内容
本实用新型的目的在于提供一种适用于饮料机的自清洗三通阀，该自清洗三通阀用于连接原料和外接水，当自清洗三通阀处于开启状态时，该自清洗三通阀的阀芯可被清洗，以清理阀芯表面存在的原料，以避免出现现有技术存在的问题。
为实现以上发明目的，本实用新型提供一种适用于饮料机的自清洗式三通阀，至少包括：三通阀体以及置于三通阀体内的阀芯；其中三通阀体至少包括管道互通的进水管道以及原料管道，阀芯置于原料管道内，当自清洗式三通阀处于开启状态时，部分阀芯暴露在进水管道内，当自清洗式三通阀处于关闭状态时，阀芯堵塞原料通道和进水管道的相接之处。
在一些实施例中，阀芯包括阀芯芯体，弹性元件以及弹性元件固定件，其中弹性元件固定件固定弹性元件的一端，弹性元件的另一端连接于原料通道的托台。
在一些实施例中，阀芯包括限位台，其中限位台置于阀芯芯体的底部，且限位台的横截面积大于原料通道的通道横截面积。
在一些实施例中，当弹性元件处于自然伸展的状态时，限位台位于原料通道和进水管道的相交之处堵塞原料通道。
在一些实施例中，原料通道为上下直径相通的通道，原料通道的通道横截 面直径大于弹性元件固定件的横截面直径。
在一些实施例中，原料通道为直径面积自上向下依次变小的通道，原料通道的最大通道横截面直径大于弹性元件固定件的横截面直径。
在一些实施例中，限位台上设置密封件。
在一些实施例中，原料通道包括第一原料通道以及第二原料通道，第一原料通道和第二原料通道之间开设至少一限流孔，阀芯置于第二原料通道内，第一原料通道连接原料存放容器。
在一些实施例中，当弹性元件处于自然伸展的状态时，阀芯芯体的芯体顶部堵塞限流孔。
相较现有技术，本技术方案具有以下的特点和有益效果：
1、当自清洗三通阀处于开启状态时，部分阀芯置于进水管道内，外接水流直接流经阀芯本身以清洗阀芯表面残留的原料，以达到自清洗的效果，阀芯被自清洗至少可带来保证配置饮料的质量和风味，减少原料资源的浪费以及降低运营成本等好处。
2、阀芯置于原料通路内通过弹性元件、弹性元件固定件来控制其运动，即，该自清洗三通阀的开启和关闭是通过控制高压原材料冲击阀芯来完成的，不需要直接电控阀芯，进而也保证了三通阀使用的安全性，因为阀芯需要部分接触水，如果采用电控阀芯的话，可能会出现漏电或者而其他安全事故。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本实用新型保护的范围。
本领域技术人员应理解的是，在本实用新型的揭露中，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系，其仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此上述术语不能理解为对本实用新型的限制。
可以理解的是，术语“一”应理解为“至少一”或“一个或多个”，即在一个实施例中，一个元件的数量可以为一个，而在另外的实施例中，该元件的数量可以为多个，术语“一”不能理解为对数量的限制。
如图1到3所示，本实用新型提供的适用于饮料机的自清洗式三通阀的结构示意图被展示，该自清洗式三通阀的阀芯置于原料管道内，当自清洗式三通阀处于开启状态时，部分阀芯置于进水管道内，外接水清洗阀芯以达到自清洗 的效果，且可实现料液和进水的充分混合。由于该自清洗式三通阀是被应用于饮料机内，自清洗阀芯不仅可保证阀芯干净清洁，同时也能保证配置饮料的质量和风味，避免饮料串味或者饮料内细菌滋生的问题。
该自清洗式三通阀至少具有三通阀体(10)以及置于三通阀体(10)内的阀芯(20)，其中三通阀体(10)至少包括管道互通的进水管道(11)以及原料通道(12)，阀芯(20)置于原料通道(12)内，当自清洗式三通阀处于开启状态时，部分阀芯(20)暴露在进水管道(11)内；当自清洗式三通阀处于关闭状态时，阀芯(20)堵塞原料通道(12)和进水管道(11)的相接之处。
具体的，阀芯(20)包括阀芯芯体(21)，弹性元件(22)以及弹性元件固定件(24)，其中弹性元件固定件(24)套置于阀芯芯体(21)上且与阀芯芯体(21)连接，弹性元件(22)一端连接于弹性元件固定件(24)，另一端连接于原料通道(12)。当自清洗式三通阀处于关闭状态时，弹性元件(22)处于自然伸展的状态，阀芯芯体(21)置于原料通道(12)内堵塞原料通道(12)和进水管道(11)的相接之处；当自清洗式三通阀处于开启状态时，弹性元件(22)被压置，弹性元件固定件(24)带动阀芯芯体(21)向着进水管道(11)的方向活动，进而使得进水管道(11)内的水流可冲洗阀芯芯体(21)。
值得一提的是，阀芯(20)包括限位台(23)，其中限位台(23)置于阀芯芯体(21)的底部，且限位台(23)的横截面积不小于原料通道(12)的通道横截面积，当弹性元件(22)处于自然伸展的状态时，限位台(23)位于原料通道(12)和进水管道(11)的相交之处堵塞原料通道(12)。
另外，原料通道(12)的底端设置托台(123)，其中弹性元件(22)的一端连接于托台(123)另一端连接于弹性元件固定件(24)，托台(123)内形成通孔，该通孔的孔径大于阀芯芯体的横截直径且小于限位台(23)的最小直 径，阀芯芯体(21)穿过该通孔。在本方案的一实施例中，托台(123)设置于原料通道(12)的内壁底端。
换言之，阀芯(20)包括阀芯芯体(21)，弹性元件(22)以及弹性元件固定件(24)，其中弹性元件固定件(24)固定弹性元件(22)的一端，弹性元件(22)的另一端连接于原料通道(12)的托台(124)。在本实用新型的一实施例中，限位台(23)的横截面形状实施为圆环状，方形，三角形或者其他形状，以匹配原料通道(12)。
另外，托台(123)的下侧和原料通道(12)之间形成卡接空间，在关闭状态时，限位台(23)卡置于卡接空间所在位置。
在一些实施例中，原料通道(12)为上下相通的的通道，原料通道(12)的通道横截面直径大于弹性元件固定件(24)的横截面直径，以此方式使得原料可经由原料通道(12)流至进水管道(11)内。
另外，在本技术方案中，阀芯(20)的状态变化随着经由原料通道(12)的原料压力变化而变化。具体的，当有高压原料进入原料通道(12)时，高压原料向阀芯(20)施加向下的压力，当该压力大于弹性元件(22)向上的弹性力时，高压原料向下挤压阀芯(20)进而驱使阀芯(20)向进水管道(11)移动，在阀芯(20)的下降过程中，弹性元件(22)向上的弹性力随之增加直到向上的弹性力和向下的高压原料压力相抵消时，阀芯(20)停止运动。而当解除高压原料的压力时，即，当不再向阀芯(20)施加向下的高压原料压力时，弹性元件(22)具有恢复自然状态的恢复力，弹性元件(22)对阀芯芯体(21)施加向上的弹性力，驱使阀芯(20)恢复关闭状态。
为了提高阀芯(20)的密封性以及保护阀芯(20)，限位台(23)上设置密封件(30)，当阀芯(20)处于关闭状态时，密封件(30)密封原料通道(11)。 当阀芯(20)在关闭状态和开启状态之间变化状态时，密封件(30)可缓冲限位台(23)直接冲击原料通道(23)，起到保护限位台(23)的作用。
另外，为了控制高压原料的向下施加的压力以及保护阀芯(20)，避免压力分散冲击阀芯(20)。原料通道(12)包括第一原料通道(121)以及第二原料通道(122)，第一原料通道(121)和第二原料通道(122)之间开设至少一限流孔(123)，阀芯(20)置于第二原料通道(122)内，第一原料通道(121)连接原料存放容器。且当弹性元件(22)处于自然伸展的状态时，阀芯芯体(21)的芯体顶部(211)堵塞限流孔(123)。
在本技术方案中，原料存放容器内可存放原料粉剂，原料料液。换言之，该自清洗式三通阀可被适用于各种类型的饮料机内使用。
本实用新型不局限于上述最佳实施方式，任何人在本实用新型的启示下都可得出其他各种形式的产品，但不论在其形状或结构上作任何变化，凡是具有与本申请相同或相近似的技术方案，均落在本实用新型的保护范围之内。
