如图1至图11所示，本发明实施例中介绍了一种洗衣机用的洗涤添加剂投放装置，其包括，向洗衣机的洗涤桶进水的贮水槽1，贮水槽1呈前端设有开口、顶面敞口的中空腔体，腔体内部安装有可向外抽取拉出、和向内推送装入的分配器盒2；分配器盒2上设有盛放洗涤剂和柔顺剂等洗涤添加剂的储液腔201；所述的储液腔201可以为独立腔室构成的、可拆卸的安装在分配器盒2上，也可以为分配器盒2上集成设置的、供洗涤添加剂盛放的储液槽2011；贮水槽1底部前端设有贮水槽出水口101，使洗涤添加剂混合液、进水水流可以经贮水槽出水口101流出贮水槽1，进入洗衣机的洗涤桶内部。分配器盒2与贮水槽1之间滑轨，便于分配器盒2可以顺畅的向外抽取与向内推送；贮水槽1的顶部敞口扣合有上盖3，上盖3将贮水槽上部敞口对应扣合封闭，实现对贮水槽1内部进行遮挡的效果。同时，上盖3内部集成设置有水路300，水路300用于将进水引入分配器盒2、将分配器盒2上设置腔室中注入的洗涤添加剂引出、将洗衣机进水水流引入、向洗衣机筒内引出进水和/或洗涤添加剂混合液等等；当然，水路300还可以向贮水槽1进水，实现将洗衣机的进水水流和/或洗涤添加剂混合液流入贮水槽1，经贮水槽1流入洗衣机筒内。
本发明实施例中，贮水槽1还连接有自动投放装置，用于将分配器盒1内的洗涤添加剂抽取至贮水槽1中；贮水槽1右侧侧面设有贮水槽进水口102，贮水槽进水口102向贮水槽1内进水，与集成水路出水口304排出的洗涤添加剂混合形成洗涤添加剂混合液，贮水槽1底部设有贮水槽引水槽103和出水口引水槽104，供贮水槽1内的洗涤添加剂混合液经贮水槽引水槽103和出水口引水槽104引导由贮水槽1底部前端设置的贮水槽出水口101流出，进入洗衣机的洗涤桶内。
本发明实施例中，洗涤添加剂投放装置上还设有自动投放单元，用于将洗涤添加剂向水路内自动抽取投放；所述的自动投放单元可以为现有的任一结构；本发明实施例中，自动投放单元可以设置如下，但本发明的保护范围并不局限于下述设置：自动投放单元包括泵，分配器盒2经泵与集成水路300相连通，使得分配器盒2内盛放的洗涤添加剂可以自动被泵送至集成水路300中，经集成水路出水口304排入贮水槽1中。
如图1至图5所示，本发明实施例中，上盖3包括相互扣合的集成水路下盖302和集成水路上盖301，集成水路下盖302和集成水路上盖301的连接面处设有相向凹陷的凹槽，集成水路下盖302与集成水路上盖301上下相互密封的相连接，使得上述凹槽直接形成了集成于上盖3内部的水路300。
集成水路下盖302设有集成水路出水口304供集成水路300内的洗涤添加剂混合液和/或进水水流流入贮水槽1，集成水路出水口304左侧设有透气孔305，以保证停止进水后，经透气孔305向水路300内换气，使得水路300内的残液可以在大气压作用下全部外排至下方的贮水槽1内、达到水路内残水排空的效果。
在洗衣机工作时，为保证停止进水后水路300里的水排空，在水路300内增添一个透气孔305，因为，在进水过程中透气孔305会流出部分水，为保证透气孔305流出的水流量在一定范围内，透气孔305自水路300朝上开设、直径小于2mm，以防止水路300内的液体自透气孔305向外流出；优选的，为了进一步避免水路300内液体自透气孔305向外溢流，可以在透气孔305处加装透气阀，使得透气阀作用下，经能将气体流经透气孔305、不能将水路300内的液体流出。
本发明实施例中，贮水槽1底部前端设有贮水槽出水口101，贮水槽出水口101周围设有沿贮水槽出水口101周围向远离贮水槽出水口101方向逐渐向上倾斜的出水口引水槽104，出水口引水槽104右侧与设置于贮水槽1底部上端的贮水槽引水槽103相连接，使贮水槽1内的洗涤添加剂混合液可彻底的经贮水槽引水槽103和出水口引水槽104排入洗衣机内部。
如图1至图5所示，本发明实施例中介绍了一种洗涤添加剂投放装置，包括，贮水槽1，扣合于贮水槽顶部的上盖3，上盖3内部集成有水路300；上盖3底壁设有朝向贮水槽1内开设的水路出水口304；上盖3和/或贮水槽1设有防止自水路出水口304进入贮水槽1的进水水流溅射的防溅结构。通过加装防溅结构，以有效防止进入贮水槽内的进水水流产生过大溅射，进而实现了防止贮水槽内溅射水流向水路内回流、阻碍水路出水的显著技术进步；还能利用防溅结构阻挡溅射过激现象发生，有效避免进入贮水槽内的洗涤添加剂混合液溅射到贮水槽侧壁上、产生挂液残留等现象的发生。
本发明实施例中，所述防溅结构包括，水路出水口304下方的贮水槽1底部设有向贮水槽1中心方向向下倾斜的接水面5，接水面5上设有垂直向上延伸的防溅水筋7。通过在上盖水路出水口下方的贮水槽底壁上加装防溅水筋7，利用防溅水筋7对进水水流进行干扰分流，使得贮水槽1的进水水流的下落作用力被防溅水筋7进行分解，有效降低了贮水槽进水水流的下落速度，进而达到了对贮水槽1内进水水流防溅的效果。同时，本发明中，通过将上盖水路出水口下方的贮水槽底壁设置为向中心向下倾斜的斜面，使得贮水槽的进水水流可以沿斜面向贮水槽1内流动，有效避免了在水路出水口下方汇集水情况的发生、进一步避免了贮水槽1内溅射水流的产生。
本发明实施例中，防溅水筋7为竖直向上延伸的柱状竖筋；防溅水筋7的截面为方形；防溅水筋7的上端面为与接水面5相平行的斜面。通过将防溅水筋7的上端面设置为斜面，以使得下落至防溅水筋7处的水流可以沿上端斜面流动，进一步提升防溅水筋对下落的进水水流的分流缓冲效果、有效降低贮水槽1内的溅射水流。
本发明实施例中，所述接水面5的上表面设有呈多行多列排布的多条防溅水筋7；各防水筋7等高设置；各防水筋7的上端面处于同一平面，上述平面与接水面5相平行设置。通过在水路出水口下方区域排布多行多列防溅水筋，可以利用防溅水筋的侧壁对溅射水流进行干扰分流，进而使得溅射水流可以降低高度、有效阻碍了贮水槽内过高溅射水流产生的显著技术进步。
优选的，上述多行多列排布的防溅水筋7中，同一排防溅水筋7的排列线与贮水槽1的前后方位相交错一定角度，以使得各防溅水筋7相交错的排布，进一步提升对出水口下方各个区域处的进水水流进行缓冲防溅的效果。
本发明实施例中，接水面5朝向贮水槽1前侧开口一侧设有垂直向上延伸的条形挡板6，条形挡板6高于防溅水筋7的顶端高度。通过在接水面一侧设置挡板，使得自水路出水口进入贮水槽1的进水水流可以被条形挡板6阻挡，不会向贮水槽出口101方向溅射，有效避免了因进水而产生的溅射水流挂设在贮水槽侧壁上等情况的产生、有效杜绝了贮水槽内残留水的生成。
优选的，接水面5设置于贮水槽1的后侧一拐角处，条形挡板6设于接水面5朝向贮水槽1前侧开口一侧，条形挡板6的一侧壁与贮水槽1的对应侧壁相贴合接触，使接水面5仅利用朝向贮水槽1中部一侧供水流出。通过上述设置，使得水路进水口区域被条形挡板6和贮水槽侧壁三面包围，令流入贮水槽1的进水水流只能向贮水槽中部方向流动、沿贮水槽底 壁流向贮水槽出口。
本发明实施例中，所述防溅结构还包括，上盖3的下壁设置的出水口304处扣合安装的接水盘8；接水盘8内部中空构成过水腔室，接水盘8的上方敞口并对应扣合于上盖3的出水口304外围，接水盘8的上方敞口与上盖3的底壁相接触设有至少一圈密封圈，使得自出水口304流出的液体全部进入接水盘8的中空腔室内；接水盘8的底面设有多个间隔排布的贯穿接水盘8底面的接水盘出水孔801，令水路出水口流出的水流经接水盘出水孔801进入贮水槽1。通过在水路出水口处加装接水盘8，利用接水盘8上所设的中空腔室对水路出水水流进行缓冲，可以有效降低出水流速；同时，利用接水盘8上排布的多个出水孔，形成花洒状的出水水流，可以对出水水流进行有效分流、大大降低贮水槽1内形成溅射水流的高度，进而有效杜绝了贮水槽1内进水水流产生溅射而导致投放装置漏水等问题的产生。
本发明实施例中，接水盘8呈圆柱状，接水盘8与出水口304同轴设置，接水盘8的径向尺寸大于出水口304的径向尺寸；接水盘8底壁上开设的接水盘出水孔801全部位于接水面5的竖直上方，以使得自接水盘8流入贮水槽1内的进水水流可以自由下落至接水面5处、再收接水面5引导向贮水槽1内流入，进而实现贮水槽进水水流受接水盘8和防溅水筋7的双重防溅作用，进一步避免了贮水槽1内溅射水流的产生。
本发明实施例中，接水盘8底面所设的接水盘出水孔801为轴线竖直延伸的、朝下竖直开设的开孔；各接水盘出水孔801的至少部分位于防溅水筋7的竖直上方，进一使得自接水盘8分流后的水流下落后依然可以受防溅水筋7进行防溅作用，大大降低贮水槽1内溅射水流的产生。
本发明实施例中，接水面5为贮水槽1的底壁上表面、或为固定安装于贮水槽1内壁的独立件的上表面；优选的，接水面5由贮水槽1的底壁构成、为贮水槽1的底壁上表面的一部分。接水盘8与上盖3一体设置、或为与上盖3底壁固定相连的独立件；优选的，接水盘8为固定安装于上盖3上的独立件。
本发明实施例中，贮水槽1最右侧设有贮水槽进水口102，用于对贮水槽1内的注水，位于贮水槽进水口102前端上侧，集成水路出水口304的正下方设有底部与贮水槽1底部的接水面5相连接，垂直向上延伸的多个间隔排布的防溅水筋7。
如图1至图5所示，本发明实施例中，贮水槽1底部的接水面5设为由贮水槽1底部中部向贮水槽1内壁倾斜向上的斜面，使集成水路出水口304排出的混合液经防溅水筋减速后排向贮水槽1中部，进而经贮水槽引水槽103与出水口引水槽104排入洗衣机内部，接水面5的右侧与贮水槽1内壁相连接，左侧设有由沿贮水槽1底部垂直向上延伸的条状挡板6，条状挡板6的一侧与贮水槽1内壁相连接，另一端自由延伸设置。
如图1至图5所示，本发明实施例中，贮水槽1顶部与集成水路下盖302底面相连接，可以是可拆卸的相连接，也可以是密封的相连接，集成水路下盖302顶面设有集成水路300，集成水路下盖302与集成水路上盖301相互密封的连接构成集成水路300，集成水路300中设置有集成水路进水口303，供分配器盒2内的洗涤添加剂混合液由分配器盒2抽取流入集成水路300中，经集成水路出水口304排入贮水槽1内部，再由贮水槽1排进洗衣机内部，进而完成洗涤添加剂的投放；在集成水路出水口304的左侧，设有直径不大于2mm的圆形透气孔305，以达到集成水路300内的混合液可以完全排净的目的。
本发明实施例中，用户将分配器盒2向外拉取抽出，在分配器盒2内加入适量的洗涤添加剂，将洗涤剂盒2向内推入贮水槽1内部，然后启动洗衣程序，分水器盒2内的洗涤添加剂被抽取到集成水路上盖301与集成水路下盖302构成的集成水路300中，由集成水路进水 口303进入，经过集成水路300通过集成水路出水口304注入到贮水槽1内部，洗涤添加剂混合液经集成水路出水口304排出后，经设置于集成水路出水口304正下方的多个间隔排布的防溅水筋7对有集成水路出水口304排出的洗涤添加剂混合液进行减速缓冲，排出的洗涤添加剂混合液下游倾斜向下的接水面5引送向贮水槽1中部，再由贮水槽引水槽103与贮水槽1的出水口引水槽104将洗涤添加剂混合液投放至洗衣机内部进而完成对洗涤添加剂的投放；
如图1至图8所示，本发明实施例中介绍了一种具有防回溅结构贮水槽的洗涤添加剂投放装置，包括，由三个侧面与一个底面围成的呈左侧与顶面呈敞口的簸箕状的贮水槽1，贮水槽1的右侧设有贮水槽进水口102，经水管403与进水阀402相连通，进水阀402与洗衣机进水水源相连通，洗衣机进水水源一般为用户家的自来水水龙头；进水阀402可以控制水管的通断用于控制向贮水槽1供给自来水的通断。
如图1至图8所示，本发明实施例中，贮水槽1底部前端设有贮水槽出水口101，贮水槽出水口101与洗衣机内筒相连通，贮水槽出水口101顶部四周设有沿贮水槽出水口101四周向远离贮水槽出水口101倾斜向上的出水口引水槽104，出水口引水槽104倾斜向上最高点与贮水槽1底部内壁相平齐，出水口引水槽104的一侧连通有贮水槽引水槽103，贮水槽引水槽103横穿整个贮水槽底部一侧与出水口引水槽相连接，另一端沿前后方向自由延伸，覆盖贮水槽1底部，供贮水槽1底部的液体汇聚至贮水槽引水槽103内，经出水口引水槽104和贮水槽出水口103排放至洗衣机的洗涤桶内。
如图1至图8所示，本发明实施例中，位于贮水槽1底部的右侧贮水槽引水槽103的上方，正对集成水路出水口304的下方设置一侧与贮水槽1底部相连接，另一侧与贮水槽1侧壁相连接的，由贮水槽1壁向下倾斜的接水面5，接水面5上设有与贮水槽1壁平行设置从接水面5垂直向上延伸的防溅水筋7，多个防溅水筋7间隔排布在接水面5上，接水面5的另外两侧一侧与贮水槽1的内壁相连接，另一侧与条状挡板6相连接，条状挡板6设置为底部与贮水槽1底部相连接，顶部垂直向上自由延伸，条状的挡板6一侧与贮水槽1内壁相连接，另一侧向贮水槽1内部方向延伸，构成一个垂直向上的条长状的条状挡板6，用于阻挡集成水路出水口304排放的洗涤添加剂混合液，使其可以经接水面5流向贮水槽1内部。
如图1至图8所示，本发明实施例中，贮水槽1的顶部四周与集成水路下盖302的底部相连接，连接方式可以是卡扣式连接也可以是其他的连接方式；集成水路下盖302与集成水路上盖301相互上下的扣合密封连接形成集成水路300，集成水路300的水路启始端设置有集成水路进水口303，供洗涤添加剂的流入，在集成水路300的末端设置有集成水路出水口304，用于将集成水路300内的洗涤添加剂排出，在集成水路出水口304的左侧，设置有直径不大于2mm的透气孔305。
如图1至图8所示，本发明实施例中，位于集成水路下盖302的底部，集成水路出水口304的下方设有中空的圆柱形顶部为敞口的接水盘8，接水盘8的底部设置有多个接水盘出水孔801，以达到降低集成水路出水口304的出水速度，防止集成水路出水口304出水速度过快击接水面5造成回溅的目的。
本发明实施例中，接水盘8可以是与集成水路下盖302一体设置也可以是单独设置安装于集成水路下盖302底部，接水盘8顶部敞开的敞口罩住集成水路出水口304，使集成水路出水口304排出的混合液需经接水盘8才可排入贮水槽1内。
本发明实施例中，洗涤添加剂经集成水路进水口303进入集成水路300内部后，经集成 水路出水口304排入至接水盘8内部空腔，再由接水盘8底部接水盘出水孔801减速分流，降低流速后在经过防溅水筋7进一步的减速分流流至接水面5，通过条状挡板6的阻挡经倾斜的接水面5流向贮水槽1内部，在贮水槽1内部与贮水槽进水口102流入的水混合成洗涤添加剂混合液的同时并经贮水槽引水槽103与出水口引水槽104流至洗衣机的洗涤桶内。
如图12至图16所示，本发明提供一种洗衣机自动投放水路的泄压装置，包括一个阀芯02，阀芯02设置在泄压装置靠近水路的一端，与进水端11适配，阀芯02与出水端12之间设置一个弹性件。
具体的，泄压装置设置为单向阀，在阀芯02上设置有垫圈，一方面可以将阀芯02卡在阀体01上，另一方面可以增大其密闭性，防止正常状态下液体溢出。
具体的，阀体01内壁为自进水端11向出水端12延伸，延伸一段距离后向外侧延伸一小段，再继续向出水端12延伸至投放装置外部，垫圈卡在向外延伸的部分，防止阀芯02在弹性件的弹力下将阀芯02推出阀体01。
具体的，在阀芯02远离进水端11的一侧端面设置有一个限位柱21，所述限位柱21自阀芯02远离进水端11一侧端面的中部向远离进水端11的方向垂直于上述端面延伸。
具体的，在限位柱21的一侧设置有限位筋22，所述限位筋22包括：第一限位筋221，包括自限位柱21的周壁向相互远离的方向延伸的两部分，与限位筋22的延伸方向呈第一夹角；第二限位筋222，自第一限位筋221的端部向相互靠近的方向延伸、且端部相连，与限位筋22的延伸方向呈第二夹角。
优选的，第一夹角大于第二夹角。
具体的，可以选择弹簧03作为弹性件，弹簧03的一端与阀芯02远离进水口的一侧抵接，所述抵接一端的弹簧03一侧抵接在阀芯02远离进水端11一侧的端面上，另一侧抵接在限位筋22远离进水端11的一面上，由于上述阀芯02的端面与限位筋22远离进水端11一面在同一水平线上高度不一致，从而使弹簧03在于二者抵接时弹簧03的压缩量不同，使弹簧03两侧的弹力大小也不同。
具体的，上述的弹簧03一端套设在限位柱21上，对弹簧03起到一个限位的作用，由于上述弹簧03一端的两侧弹力不同，弹簧03受到不平衡的力，所以在阀芯02向下移动时，会发生倾斜偏移，弹簧03抵接阀芯02的一端受到斜向上的力并向斜上方移动，若不增加限位柱21，弹簧03将会与阀芯02脱离，阀芯02降下后失去了弹簧03向上施加的弹力，导致进水口不能及时被密封上，水路内的液体就会持续的通过泄压阀向外溢出，造成了极大的浪费。
具体的，弹簧03一端套设在限位柱21上，当阀芯02向下移动时，弹簧03对阀芯02有一个倾斜的力，使弹簧03相对于阀芯02产生偏移，在弹簧03一侧偏移至抵接到限位柱21时，弹簧03停止偏移，进而避免了弹簧03与阀芯02脱离的问题发生。
优选的，限位筋远离限位柱的一端与限位柱抵接弹簧的一侧的距离大于或等于弹簧簧圈的直径，此时阀芯02向下移动，一侧偏移至抵接到限位柱21时，弹簧03的另一侧依旧可以抵接在延伸出阀芯02的部分限位筋22，一方面，防止了弹簧03远离限位柱21的一侧在偏移时突然与限位筋22脱离，增加了其稳定性；另一方面，也防止了弹簧03远离限位柱21的一侧在偏移时突然与限位筋22脱离时弹簧03产生的异音，进一步减小了噪音的大小。
具体的，出水端12内部中空，远离进水端11的一侧与外界相通，在出水端12的内部设置有一个第一限位部121和一个第二限位部122。
具体的，第一限位部121，沿出水端12的径向延伸，两端与出水端12内壁固定；优选 的，第一限位部121包括相互交错设置的多个，各第一限位部121靠近阀芯02的一端共面；第二限位部122，设置在出水端12轴心处，位自第一限位部121向进水端11的方向凸出延伸的圆柱体；弹性件的另一端抵接在出水端12的第一限位部121上，并套设在第二限位部122的外周。
具体的，由于管道内水路压力不稳定，阀芯02受到水路的压力也不稳定，若弹簧03直接抵接在阀芯02远离进水端11的端面，在阀芯02来回移动时会产生径向抖动异音，若将弹簧03抵接阀芯02的一端设置为倾斜的，可以减小这部分的异音。
具体的，弹簧03与限位筋22抵接一侧到第一限位部121的距离小于弹簧03与阀芯02远离进水端11的端面抵接一侧到第一限位部121的距离，进而使弹簧03与限位筋22抵接一侧的压缩量大于弹簧03与阀芯02远离进水端11的端面抵接一侧的压缩量，弹簧03与限位筋22抵接一侧的弹力大于弹簧03与阀芯02端面抵接一侧的弹力，当水路流量变大，内部压力变大时，阀芯02受往下的力大于弹簧03力，阀芯02向出水端12移动，由于弹簧03两侧压缩量不一致，阀芯02受力不平衡，此时阀芯02受到倾斜的力，阀芯02移动还需要克服弹簧03的倾斜力，从而避免了阀芯02的抖动异音。
具体的，第一限位部121的延伸方向应设置为与限位筋22的延伸方向相同，弹簧03两侧的压缩量不同，在阀芯02向下移动时，弹簧03靠近进水端11的一端向远离限位筋22的方向倾斜，同时也导致远离进水端11一端的弹簧03发生倾斜，若此时第一限位部121延伸方向为与限位筋22的延伸方向相垂直，则弹簧03将会以第一限位部121为轴心发生旋转倾斜，弹簧03簧圈的内部卡在第二限位部122上，短时间内在第二限位部122的作用下可以阻止弹簧03由于旋转倾斜从出水端12处滑落，在使用过程中，第二限位部122持续给弹簧03簧圈施加力，长久以往会导致弹簧03簧圈被拉伸变大，进而第二限位部122不能再很好的起到限位作用，最终导致弹簧03从出水端12滑落。
具体的，若第一限位部121的延伸方向设置为与限位筋22的延伸方向相同，在阀芯02向下移动时，弹簧03靠近进水端11的一端向远离限位筋22的方向倾斜，同时也导致远离进水端11一端的弹簧03发生倾斜，此时弹簧03倾斜方向被第一限位部121限制，阻止了弹簧03继续倾斜从而导致弹簧03滑落，但在装置工作过程中，由于弹簧03经常发生倾斜偏移，导致阀芯02在弹簧03的作用下，在其竖直方向上会发生沿着轴向旋转的偏移，进而使限位筋22的延伸方向与第一限位部121延伸方向的夹角发生改变，长时间使用过程中，还是会发生弹簧03以第一限位部121为轴心发生旋转倾斜的情况，这是第二限位部122依旧对弹簧03的簧圈施加压力，导致弹簧03簧圈被拉伸变大，进而第二限位部122不能再很好的起到限位作用，最终导致弹簧03从出水端12滑落。
优选的，第一限位部121可以设置为两个相互交叉的条形块，垂直的穿过出水端12轴心并且各条形块的两端固定在出水端12内壁，在只设置了一条第一限位部121的情况下，弹簧03在抵接的时候会不稳定，当阀芯02向下移动时，弹簧03抵接阀芯02的一端向没有限位筋22的一侧倾斜，进而导致弹簧03抵接第一限位部121的一端也发生倾斜，若倾斜的方向正好为第一限位部121的两边，弹簧03则会从两边的缝隙中掉落，阀芯02就不能回到原位，水路中的液体持续不断的从出水端12流出，造成浪费。
优选的，交叉设置的第一限位部121其相交的角度设置为90度，互相垂直的第一限位部121具有更强的稳定性，两条相互垂直的第一限位部121就可以基本解决弹簧03从出水端12滑落的问题，为了使其稳定性更高，可以设置更多的第一限位部121或将第一限位部121设置为网状盘，网状盘的外沿与出水端12内壁相贴合、相适配，但第一限位部121设置过多的话，占用的空间也会变多，留给液体从空隙中流出的空间就越小，向外溢出的速度 相应的也会变慢，当水路压力过大的时候，需要溢出更多的液体来平衡水路压力，若这些多余的液体没有及时的溢出，导致堆积在泄压阀内，就不能实现对水路的泄压功能，同样的，若将第一限位部121设置为网状盘，一方面稳定性得到了很大的提高，但同时其通过性也被限制，综合来看，第一限位部121设置为两条相互交叉的条形块，并且两个条形块互相垂直的方案为最优选。
具体的，在其它可能的实施例中，出水端12设置为阀体01出水端12的中部向远离出水端12的方向凸出的圆柱体，圆柱体内部中空，出水端12靠近进水端11的一端为开口，出水端12远离进水端11的一端为封闭，所述封闭一端的端面为第一限位部121，自第一限位部121中部设有向进水端11的方向垂直于第一限位部121延伸的第二限位部122，第二限位部122中部设有通孔，使阀体01内部与外界连通，多余的液体从第二限位部122中部的通孔溢出。
具体的，当水路压力过高时，多余的液体流进阀体01，液体先会堆积在第二限位部122外周、出水端12内壁与第一限位部121所围成的空间内，当液体的高度高于第二限位部122的时候从第二限位部122中部的通孔流出，第二限位部122的直径可以设置为与弹簧03簧圈内壁的直径相同，弹簧03套设在第二限位部122上，弹簧03簧圈内壁与第二限位部122外周面抵接，这样一方面可以对弹簧03起到更好的固定作用，另一方面，曾加了第二限位部122直径，第二限位部122中部的通孔也可以随之增大，可以加快液体溢出的速度，由于在液体从第二限位部122中部溢出之前会事先堆积在第二限位部122外周、出水端12内壁与第一限位部121所围成的空间内，弹簧03在长时间被液体浸泡的情况下会出现生锈等问题，从而降低了弹簧03的使用寿命，针对此问题，有如下解决方案。
具体的，一是将弹簧03远离进水口的一端直接固定在第二限位部122靠近进水端11的端面上，这时只有当水位到达第二限位部122顶端时弹簧03才会接触到液体，其余状态下水位达不到接触弹簧03的高度，减少了弹簧03与液体的接触时间；二是在第二限位部122的周壁上设置有多个通孔，该通孔与第二限位部122中部贯穿的通孔相同，此时液体流进出水端12后，无需在等水位达到第二限位部122顶部再将其溢出，在到达顶部之前可以通过第二限位部122周壁的通孔将液体溢出；三是将第一限位部121设置为网状，通过第一限位部121来实现溢水的功能，若水路压力过大时，需要溢出的水量变多，第一限位部121网状结构的溢水效率不足以将液体全部排出，这时第二限位部122中部的通孔依旧可以继续发挥作用，使装置正常工作。
具体的，阀芯02设置有过水部23，过水部23包括：中心柱231，与阀芯02主体同轴设置；支撑筋232，自中心柱231的周壁沿径向向远离中心柱231轴线的方向延伸，远离中心柱231轴线的一侧与进水端11的内壁抵接，包括沿周向均匀排列的至少三根。相邻的支撑筋232之间设有导流槽234，该导流槽234自阀芯02的顶部向底部继续延伸，延伸的长度保证在正常状态下阀芯02与进水端11密封。
具体的，导流槽234的设置用于将水路中的液体引导至泄压阀内，在水路压力在正常范围内时，阀芯02保持静止，阀芯02顶部的导流槽234之间存有一定量的液体，当水路压力增大时，由于导流槽234向阀芯02底部延伸了一段距离，在阀芯02向下移动了小段距离时多余的液体就会从导流槽234中流向阀体01内，可以使水路中的压力快速减小，从而达到一种动态平衡的效果。
如图15、图16所示，一种洗衣机，包括水盒，水盒内设置有投放水路，上述实施例一中的水路泄压装置设置在水盒上，进水端与投放水路相连。
所述水路泄压装置集成在所述水盒上。具体的，水盒上设置有一个堵头4，所述堵头4 设置在泄压装置的出水端12，泄压装置自进水端11向出水端12垂直于水路设置。
具体的，堵头4设置为一个中部有通孔的圆柱体，圆柱体的外周与出水端12相适配，在圆柱体远离进水端11的一侧设有连接部41，所述连接部41设置为自圆柱体相对的两侧向远离圆柱体的方向延伸，在延伸的部分设置有连接孔411，在水盒上设置有与连接孔411相适配的安装部。
具体的，堵头4与水盒通过螺钉固定连接，螺钉穿过连接孔411旋转拧入安装部，将堵头4与水盒固定，堵头高出部分插接在出水端12，第一限位部121和第二限位部122设置在堵头4的通孔内。
