具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，若本申请实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请提出一种软水阀的射流器。在本申请实施例中，如图1至图5，以及图11所示，该软水阀的射流器包括：射流部1，内部形成有射流孔111，射流孔111沿射流方向呈渐缩设置；汇流部2，内部形成有汇流孔211，汇流孔211的入口与射流孔111的出口相对设置，汇流孔211的入口孔径大于射流孔111的出口孔径，汇流部2与射流部1相向的端面之间形成吸盐口3；以及连接部4，固定连接射流部1及汇流部2，且连接部4、射流部1及汇流部2一体设置。
在本实施例中，射流部1的射流孔111其内壁面的剖面形状可以是相对设置的斜线、弧线或抛物线等具备渐缩特征的形状，由于内径逐渐缩小，通常为原水的引水水流在射流孔111内逐渐加速，最后以较快的速度喷入吸盐口3，而盐水位于吸盐口3的部分或邻近吸盐口3的部分的无流速或流速接近零，如此盐水被吸入引水水流，并随引水水流一起进入汇流部2的汇流孔211，通过设置引水水流的压力、盐水的压力、射流孔111、吸盐口3及汇流孔211的大小，可以控制引水与盐水之间的比例配比。通过将汇流孔211的入口孔径设置成大于射流孔111出口的孔径，可以提高引水及盐水合流后进入汇流孔211的几率。射流器200既可以采用注塑工艺形成一体的结构，也可以采用金属压铸或机加工的方式，但优选地采用一体注塑工艺。
本申请软水阀的射流器200通过设置一体的射流部1、汇流部2及连接部4，使得射流器200可以整体制造，在软水阀的装配中，射流器200内部不需要密封，所需的装配步骤少，射流孔111与汇流孔211的对中，吸盐口3的大小和形状，均可以在制造阶段既可以确定，组装部分简单，并且装配后可以确保射引吸盐的效果，工作的可靠性更好。
在本实施例中，所述汇流孔211的内壁面凸设有多个沿着所述射流方向延伸的引流凸筋214，每相邻两所述引流凸筋214之间形成引流槽215，以在所述汇流孔211的内壁上形成多个并行的引流槽215。通过在所述汇流孔211的内壁面凸设有多个沿所述射流方向延伸的引流凸筋214，所述多个引流凸筋214之间形成多个并行的引流槽215，该多个并行的引流槽215用以对所述汇流孔211中的水流进行导流，从而减缓所述汇流孔211的水流因压差造成的水流紊乱，进而可以校直水流使水流稳定，减小所述射流器200产生的噪音和振动，提高用户的使用体验。
进一步地，汇流孔211包括扩口段212及平口段213，扩口段212沿射流方向呈渐扩设置，扩口段212邻近射流部1，平口段213连接在扩口段212沿射流方向上的远端。在本实施例中，通过设置扩口段212，引水和盐水混合后可以逐渐降低流速，进而避免振动或共振，进而产生额外的噪音。
进一步地，请参照图1、图3、图5及图6，在一实施例中，所述引流凸筋214设置于所述平口段213。在本实施例中，混流后的水流流经扩口段212时虽然能降低流速，但仍然有可能在汇流孔211内产生紊流，进而引起振动。通过在所述平口段213设置引流凸筋214进行引导、分流，水流可以更为平稳地流经汇流孔211。
所述多个引流凸筋214的排布形式可以等间距均匀排布，也可以非等间距排布，具体地，在本实施例中，请参阅图6，所述多个引流凸筋214沿所述汇流孔211的周向均匀分布于所述汇流孔211的内壁面。所述多个引流凸筋214的该周向均匀分布设置，均匀分布后，使所述多个引流凸筋214之间形成的多个引流槽215大小一致，从而对水流的导引作用一致，以将所述汇流孔211中的水流匀均导流，进而可以对水流更好的分流，即分流地更为平稳，流出的水流更稳定，进一步稳定所述汇流孔211中的水流，降低水流振动产生的噪音，使水流更加平稳，噪音更低。进一步，更具体地，在本实施例中，请参阅图3，所述多个引流凸筋214设置为4条。所述多个引流凸筋214的具体数量可以根据所述射流器的大小相应设置多个，在此不做限定。
进一步地，引流凸筋214具有与平口段213内壁相连的凸弧面，凸弧面与平口段213内壁的交线在平口段213周向的宽度沿射流方向呈渐扩设置。在本实施例中，通过以凸弧面构成引流凸筋214的外表面，使得引流凸筋214在引流导向时对水流产生的阻力更小，而通过将引流凸筋214设置渐宽的结构，可以对水流更好的分流，即分流地更为平稳。如图所示，通过在平口段213的内壁面设置四条引流凸筋214可以将沿平口段213内壁面流动水流分为四股。
进一步，更具体地，请参阅图5，在所述汇流孔211的出口处，所述多个引流凸筋214的截面积与相应的引流槽215的截面积相当。该设置使所述汇流孔211的出水口的截面水流与其进水口的截面水流相当，以使所述汇流孔211的出口的水流量与其进口的水流量相当，以便于在树脂吸盐再生时，稳定水流流速，从而便于树脂软化再生时间的控制，以及用盐用水的消耗量的控制，进而避免盐水用量不足使树脂再生不充分，或盐水用量过量使树脂过分再生，以避免造成不必要的浪费。
所述多个引流凸筋214的具体结构设置可以有多种设置，具体地，在本实施例中，请参阅图5，所述多个引流凸筋214在所述射流方向上呈渐扩设置。该设置使所述多个引流凸筋214形成的多个引流槽215在导流时，避免对水流产生较大的阻力，从而使水流逐渐趋于平缓，避免因压差造成的水流紊乱，进而校直水流，保持水流稳定。
设置所述多个引流凸筋214在所述射流方向上呈渐扩设置，可以有多种凸设形式，具体地，在本实施例中，请参阅图5和图6，所述多个引流凸筋214的凸设高度沿水流方向逐渐增大；和/或，所述多个引流凸筋214的凸设宽度沿水流方向逐渐增大。所述多个引流凸筋214的凸设高度或凸设宽度的渐变增大设置，通过逐渐缩小所述汇流孔211的截面积，以使所述汇流孔211的截面水流与其进水口的截面水流相当，从而便于在树脂吸盐再生时，稳定水流流速，控制树脂软化再生时间和用盐用水的消耗量。本实施例中，所述多个引流凸筋214可以是凸设高度沿水流方向逐渐增大，也可以是凸设宽度沿水流方向逐渐增大，当然还可以是凸设高度和凸设宽度均沿水流方向逐渐增大。当然，所述多个引流凸筋214的具体凸设结构还可以是其他形式，只要是能实现本实施例的功能即可，在此不做限定。
进一步地，更具体地，请参阅图5和图5，所述多个引流凸筋214的凸设高度或凸设宽度范围有相应的设置，具体地，在本实施例中，所述多个引流凸筋214的凸设高度或凸设宽度范围为0~3mm。该设置使所述多个引流凸筋214对所述汇流孔211内水流的阻力不至于太大，且在所述汇流孔211的出口处，所述多个引流凸筋214的截面积与相应的引流槽215的截面积相当，以使所述汇流孔211的进水口的水流量和出水口的水流量相当。
进一步地，为了更好地平缓所述射流器200的汇流孔211内的水流，降低水流振动产生的噪音，所述多个引流凸筋214的表面结构具有相应的设置，具体地，在本实施例中，请参阅图5，所述多个引流凸筋214的外表面呈圆弧面设置。在其他实施例中，所述多个引流凸筋214可以是其表面呈直面设置，也可以是其表面呈斜面设置，在本实施例中，该圆弧面设置使得所述多条引流凸筋214在引流导向时对水流产生的阻力更小，更好地稳定所述汇流孔211中水流，以降低水流振动产生的噪音。
进一步地，射流部1包括第一筒体11及第一配合部12，射流孔111形成于第一筒体11，第一配合部12设于第一筒体11远离汇流部2一端，第一配合部12用以与软水阀的射流通道密封配合；汇流部2包括第二筒体21及第二配合部22，汇流孔211形成于第二筒体21，第二配合部22设于第二筒体21远离汇流部2一端，第二配合部22用以与软水阀的射流通道密封配合。
在本实施例中，第一配合部12及第二配合部22既可以为槽也可以为凸起，还可以为螺纹结构，只要方便与射流通道的内壁面进行密封即可。通过以第一筒体11形成射流孔111及以第二通体形成汇流孔211，保证了射流部1及汇流部2的壁厚均匀，是的射流器200更易于采用一体注塑形成的工艺。
进一步地，第一配合部12凸设于第一筒体11的外周面，第二配合部22凸设于第二筒体21的外周面；第一配合部12、第一筒体11的外周面、第二筒体21的外周面以及第二配合部22之间形成与吸盐口3连通的缓冲凹部5。
在本实施例中，通过设置缓冲凹部5可以使得吸盐口3可以充盈足够多的盐水，进而在引水快速穿过吸盐口3，部分盐水被吸走时可以迅速的补充，提升吸盐效率。
进一步地，第一配合部12远离汇流部2的一端设有环形的台阶槽121，台阶槽121用以安装一密封圈；第二配合部22远离射流部1的一端设有倒角221，倒角221的倒角221面用以与另一密封圈抵接。在本实施例中，密封射流器200时，一密封圈可以预先装配至射流器200上的台阶槽121，另一密封圈可以预先装配至射流通道的台阶面上或凹槽内，装配过程快捷简单。密封圈可以采用标准件易于获取且成本低。
进一步地，第一筒体11与第二筒体21同轴设置，且第一筒体11的外径与第二筒体21的外径相等。在本实施例中，射流孔111及汇流孔211位于同一轴线上，避免换向对水流造成额外的阻力。此外，通过将第一筒体11及第二筒体21设置成同轴的结构也有利于射流器200的制造。
进一步地，连接部4的数量为多个；连接部4的一端连接于第一筒体11朝向第二筒体21的端面，且邻近第一筒体11的外周面设置；连接部4的另一端连接于第二筒体21的端面，且邻近第二筒体21的外周面设置。在本实施例中，连接部4连接在第一筒体11及第二筒体21端面的外缘处，如此可以减小对吸盐口3处空间的占用，同时可以增强连接射流部1及汇流部2的强度。优选地，作为平衡，连接部4的数量为两个，且两连接部4位于同一平面上，如此，既可以减小阻碍，又能保证应有的连接强度。
本申请还提出一种软水阀，包括阀体100，阀体100包括阀腔110、射流通道及吸盐通道130；软水阀还包括软水阀的射流器200，该软水阀的射流器200的具体结构参照上述实施例，由于本软水阀采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，射流器200设于射流通道，吸盐通道130与射流器200的吸盐口3相接。
在本实施例中，引水自射流器200的入口进入射流器200，引水的来源可以直接注入，也可如一般的软水阀一样，依次经软水阀的进水口、阀腔110、再生引水通道进入射流器200。阀腔110内的阀芯动作可以连通进水口与再生引水通道。射流通道的出口用以连通阀腔110，并经由阀腔110与阀芯配合连通软水机的离子交换滤料存储腔，如软化树脂存放腔，以实现正洗；或经由阀腔110与阀芯的配合连通软水机的中心管以实现反洗。吸盐通道130的入口用以与软水机的盐箱连通，吸盐通道130与射流通道连通，射流器200设于射流通道的连接处，以使吸盐口3与吸盐通道130连通。
进一步地，射流通道包括正洗射流通道120a以及反洗射流通道120b，阀体100包括正洗通道140及反洗通道150，射流器200的数量为两个；两射流器200分别设于正洗射流通道120a及反洗射流通道120b；吸盐通道130与两射流器200的吸盐口3均连通；正洗通道140的出水口与正洗射流通道120a的入水口连通，反洗通道150的出水口与反洗射流通道120b连通；软水阀还包括切换单元，切换单元用以在正洗时连通正洗通道140正洗射流通道120a，在反洗位置时连通反洗通道150射流通道。
在本实施例中，通过分别设置用以正洗的射流通道以及用以反洗的射流通道，并分别在该正洗射流通道120a以及反洗射流通道120b设置射流器200，一方面可以简化软水阀阀芯的动作，另一方面可以适应正洗和反洗的不同工况，设置不同规格的射流器200在两射流通道内。
切换单元用以配合阀芯组件以实现相应的正洗水路及反洗水路，其与阀芯组件是协作关系，两者皆可以同时动作，也可以一前一后或，先调节阀芯组件再调节切换单元，即两者动作在时间上可不作要求。同样地，切换单元既可以通过手动也可以自动方式实现。
可选地，切换单元包括长塞头310及短塞头320。阀体100上外侧面设有连接至正洗射流通道120a的第一塞口，以及连接至反洗射流通道120b的第二塞口，通过将长塞头310安装至第二塞口，以及短塞头320安装至第一塞口可以实现正洗；以及，通过将长塞头310安装至第一塞口，以及短塞头320安装至第二塞口可以实现反洗。
更进一步地，在本实施例中，请参阅图13和图15至图19，所述软水阀的阀体100的吸盐通道130的内壁设有环形的安装槽160，安装槽160具有朝向注水方向的第一侧壁面161、与第一侧壁面161相对的第二侧壁面162，以及位于第一侧壁面161及第二侧壁面162之间的底壁面163；所述软水阀还包括限流器400，由弹性材质制成环状并设于安装槽160，限流器400的中部形成限流孔411，限流孔411的孔径沿注水方向呈渐缩设置；限流器400与底壁面163过盈配合，且限流器400可沿靠近第一侧壁面161或第二侧壁面162的方向滑动。
本实施例中，可以理解的是阀体100除了吸盐通道130，还设置有任何现有射流通道，进水通道，出水通道及废水通道，以及与各通道连通的阀腔110。阀体100既可以为一体的结构，也可以为分体的结构，为了适应批量生产，通常采用多个零部件组装而成的分体结构。安装槽160的具体形状可以不作限制，只要能方便与限流器400配合即可。进一步地，第一侧壁面161与第二侧壁面162相平行设置，底壁面163与第一侧壁面161或第二侧壁面162平行。限流器400通常采用橡胶或硅胶材质制成，以更好地缓冲冲击及与底壁面163滑动配合。限流孔411的渐缩结构，可以仅为某几段严格地“渐缩”，剩余的孔径不变。渐缩的形式可以为倾斜，圆弧，或抛物线等形成。
本申请软水阀的注水吸盐组件通过将限流器400与底壁面163避免过盈配合，如此，一方面水流无法从限流器400的外周面412与安装槽160的底壁面163之间的间隙和限流孔411之间同时流过，避免两股水流引起限流器400振动；另一方面，由于限流器400又与底壁面163滑动配合，限流器400与第一侧壁面161或第二侧壁面162之间形成避让间隙，在注水工况，限流器400向靠近第一侧壁面161的方向滑动，在吸盐工况限流器400向靠近第二侧壁面162的方向移动，通过滑动的方式抵消水流的冲击进而减小振动。因限流器400的本身的振动小，相应地产生的噪音也小，并且限流孔411的形状不易变形如此可以起到较好的限流效果。
进一步地，请一并参照图18及图19，在一实施例中，限流器400包括均呈环状设置的本体410及凸脊420，限流孔411形成于本体410，凸脊420设于本体410的外周面412，凸脊420与底壁面163紧配合。本实施例中，通过设置凸脊420而不是与限流器400等宽的圆周面与底壁面163紧配合，可以减少限流器400滑动时的摩擦力，避免因摩擦力过大而导致缓冲效果不理想。
进一步地，本体410具有朝向第一侧壁面161的第一端面413以及朝向注水方向的第二端面414，凸脊420邻近第二端面414设置。本实施例中，注水工况中，限流器400以凸脊420为支点，限流孔411的内壁面在液压的作用下，使限流器400在注水方向上的远端产生外翻的效果，直至第一端面413与本体410的外周面412的连接处与安装槽160的底壁面163抵接。如此限流孔411在注水工况下的入口得到扩大，进而达到扩大注水流量的目的。可选地，本体410的第二端面414与本体410的内周面415之间形成有圆角。如此，水流可以较为平滑地流过限流器400。
进一步地，凸脊420具有第一表面421以及沿本体410的径向向外的方向延伸的第二表面422，第二表面422朝向第二侧壁面162，第一表面421沿本体410的径向向外的方向以及靠近第二表面422的方向延伸。本实施例中，第一表面421倾斜延伸使得在注水工况中，限流器400在注水方向上的远端外翻的所需的作用力更小，进而可以更快地扩大注水工况下的入口。此外，在沿注水方向将限流器400装入安装槽160时，第一表面421倾斜延伸还可以形成导向作用，使得限流器400的装配更顺利。
进一步地，阀体100包括主体170及连接头180，主体170内部形成内段通道131，连接头180内部形成外段通道132；连接头180的一端可拆卸连接于主体170，以使外段通道132与内段通道131相接形成吸盐通道130；连接头180的另一端凸出主体170以形成接口181，限流器400设于连接头180与主体170的连接处。
本实施例中，连接头180与主体170之间的可拆卸连接，既可以通过螺栓、螺钉，也可以通过端盖190等第三部件紧固，也可以直接通过卡接或螺纹连接的方式直接实现可拆卸固定。通过将阀体100设置成分体的主体170和连接头180，并将限流器400设于连接头180与主体170的连接处，使得装配限流器400的空间更大，装配更易于进行。限流器400既可以先装配至连接头180，也可以先装配至阀体100的主体170。连接头180形成与主体170的接口181可以方便地与连接盐箱的软管连接。可选地，第一侧壁面161及底壁面163形成于连接头180，第二侧壁面162形成于主体170。如此，限流器400可以先装配至连接头180，然后再随连接头180装配至主体170。
进一步地，主体170在内段通道131的注水出口处设有环绕该出口的第一凹部171，第一凹部171具有邻近内段通道131的第一周面172；连接头180还设有与底壁面163相连的第二凹部182，第二凹部182具有与第一周面172相对的第二周面183；软水阀的注水吸盐组件还包括与第一周面172及第二周面183密封配合的密封圈500。
本实施例中，通过第一凹部171连接头180的一端可以相对嵌入主体170，如此可以得到较好地支撑。通过设置密封圈500与第一周面172及第二周面183密封配合，则可以避免分体设置拼合的吸盐通道130在连接头180与主体170的连接处产生漏水。
进一步地，阀体100还包括可拆卸盖合在主体170外侧的端盖190，端盖190开设有与接口181适配的过孔151，连接头180还设有与过孔151的边缘抵接的凸肩144。
本实施例中，可以理解的是，端盖190还用以盖合阀体100上其他的工艺孔或限位其他零部件，通过设置端盖190一体地限位连接头180可以使阀体100的结构更为紧凑。再将端盖190与主体170紧固后，端盖190内侧面于凸肩144限位，使得连接头180无法向外脱出。
本申请还提出一种软水机，包括离子交换罐（图未示）、盐箱（图未示）以及软水阀，该软水阀的具体结构参照上述实施例，由于本软水机采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
