背景技术
高压清洗机主要用于对庭院、栅栏、车辆等进行清洗，市场上现有的手持枪式直流清洗机一般都是一块低电压的电池，该电池由于电压低、容量小，因此在直流工作时，机器功率相当小，机器出水压力很小、流量低，而且续航时间也很短，清洗效果很差，只能满足一些浮层等轻度清洁场景，基本上不能满足需要中度或深度清洁的工作场景。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
本申请揭示了一种清洗机100，用于家用清洁领域，可以用于庭院、栅栏、车辆等的清洗，也可以用于户外无电源的使用场景，如野炊后的餐具、码头、轮船、游艇等的高压清洗。
如图1与图2所示，清洗机100包括下支架组件10、固定在下支架组件10上的动力头组件20、自下支架组件10向上延伸的上支架组件30以及与上支架组件30相连的清洗组件40。
下支架组件10既能够作为动力头组件20的安装底托，也能作为推动清洗机100整机行走的支撑。具体地，下支架组件10包括下支架11、支架脚垫12、安装底板13、行走轮14和螺钉15，其中，支架脚垫12设于下支架11的底部中间位置处，用于防止下支架11与地面接触时发生打滑，使清洗机100能够稳定地放置在地面上；动力头组件20安装固定在安装底板13上；行走轮14通过螺钉15与下支架11组装固定，行走轮14设置有两个并分设在下支架11的两侧，不仅能够起到支撑清洗机100的作用，还能带动清洗机100行走。
如图3至图6并结合图1所示，动力头组件20既能够为清洗机100提供动力及高效强劲的清洁性能，也能为电机泵组件22和驱动组件24提供水冷却散热方案，还能为电机泵组件22提供强大的电源保障。动力头组件20包括壳体组件21、电机泵组件22、电池包组件23及驱动组件24，其中，壳体组件21包括下壳体211、与下壳体211相互组装的上壳体212、至少部分收容在上壳体212内的电池包腔体213以及遮盖在电池包腔体213顶部的盖体214。
具体来讲，下壳体211呈凹形设置，下壳体211的底部开设有若干通孔2111，这些通孔2111均贯穿下壳体211设置，使得下壳体211的内部空腔与外界连通。上壳体212也呈凹形设置，并与下壳体211通过螺钉组装固定，上壳体212与下壳体211组装之后形成第一收容腔2113、第二收容腔2114和第三收容腔2115。其中，第一收容腔2113位于第二收容腔2114与第三收容腔2115之间，电机泵组件22收容在第一收容腔2113内并自第一收容腔2113伸出壳体组件21，电池包腔体213收容在第二收容腔2114和第三收容腔2115内并自 第二收容腔2114和第三收容腔2115伸出壳体组件21。通孔2111的设置，使得电池包组件23在电池包腔体213内产生的热量能够通过该通孔2111散发出去。
上壳体212的中间位置处设有电源开关2121和模式开关2122，其中，电源开关2121用于控制动力头组件20的启停，模式开关2122配置为能够为动力头组件20提供多种工作模式。比如：为延长动力头组件20的续航时间，可以作为降低功率的节能开关(ECO模式)，即按下此开关，电机泵组件22能够以预设的低功率档位运行，以增加续航时间；也可以作为短时增加功率和增强清洁效力的强功能开关(TURBO模式)，即按下此开关，电机泵组件22可在预设的高功率档位下短时运行，以较高的功率输出更高的水压或流量以达到更佳的清洁效果。当然，也可以同时设置以上两种工作模式，以增加用户的不同场所的使用体验。需要说明的是，本申请只体现了上述的节能工作模式方案，但不应以此为限。
在节能模式(ECO模式)下，动力头组件20的总功率不低于1.8KW，工作压力不低于10MPa，流量不低于450L/H，此时用户可以在处理不太严重的清洗工作时，使清洗机100在低档位模式下以较低的功率工作，以增加其续航时间。在强功率(TURBO)的短时(小于30SEC)工作模式下，动力头组件20可以以更高的功率输出更大的压力(不小于20MPa)，为用户提供了可选择的多种工作场景，即需要中等程度清洁的场景(10MPa)、高难清洁程度的场景(18MPa)、顽固清洁程度场景(20MPa)，基本实现了对于汽油清洗机使用场景的全替代。
第二收容腔2114和第三收容腔2115分设在上壳体212和下壳体211的两侧，电池包腔体213包括收容在第二收容腔2114内的第一收容部2131、收容在第三收容腔2115内的第二收容部2132以及连接第一收容部2131和第二收容部2132的连接部2133，第一收容腔2113形成于连接部2133的下方并将第一收容部2131和第二收容部2132间隔开。也就是说，电池包腔体213整体呈H型设置，连接部2133位于中间，第一收容部2131和第二收容部2132位于两侧，如此减小了壳体组件21的体积，使得壳体组件21的内部空间排布更紧凑，空间占用率也更高。连接部2133上开设有空腔2134，使电源开关2121和模式开关2122暴露，从而便于用户操作电源开关2121和模式开关2122。
电池包组件23安装在电池包腔体213的第一收容部2131和第二收容部2132内，电池包组件23由一个或多个可拆卸的电池包231构成，多个可拆卸电池包231之间可通过串联和/或并联的方式将供电电压转换为电机泵组件22的工作电压。具体地，本申请采用了四个大容量电池包(80V/5AH)的设计，使得总电量保证大于800WH，最小运行时间大于15min，并且可以通过更换电池包231来进一步提升续航时间。本实施例中，四个电池包231采用相互并联连接的供电方案为整个清洗机100供电；当然，在其他实施例中，也可以采用其它连接方式为清洗机100供电，比如：多个低电压的电池包231采用相互串联的方式供电，或者多个电池包231采用串联与并联相结合的方式供电，此处不再赘述。
盖体214设置有两个并分别与上壳体212的两侧边缘呈翻转式安装，以暴露电池包腔 体213的第一收容部2131和第二收容部2132，从而方便插入或取出电池包231。每个盖体214上均设有翻转转轴2141和套设在翻转转轴2141两端的翻转弹簧2142，当打开盖体214时，翻转转轴2141同步转动并使得翻转弹簧2142被拉伸；松开盖体214后，翻转弹簧2142带动盖体214自动闭合。本实施例中，盖体214可以通过翻转转轴2141翻开达到90-100度角，以方便插入或取出电池包231，翻转弹簧2142为扭簧，当松开盖体214时，可以通过布置于翻转转轴2141两端的扭簧的反作用力使盖体214自动闭合。
为了避免盖体214闭合时与电池包腔体213产生碰撞的声音，本申请在上壳体212内设计了阻尼器2123，该阻尼器2123可以在盖体214与电池包腔体213接触前，与布置于翻转转轴2141中间位置处的第一压块2143先接触，以降低盖体214的闭合速度，消除产生的碰撞声音；同时布置于翻转转轴2141中间位置处的第二压块2144可以使布设于上壳体212上的断电开关2124重新闭合，使电路处于导通状态。具体来讲，翻转转轴2141的中心位置处设有第一压块2143和第二压块2144，上壳体212内对应设有阻尼器2123和断电开关2124，第一压块2143配置为在盖体214自动闭合时优先与阻尼器2123接触，以消除在自动关闭盖体214时翻转弹簧2142与电池包腔体213所产生的碰撞声音，使用户体验更佳。第二压块2144配置为在盖体214处于闭合状态时与断电开关2124相抵接，使断电开关2124导通；而在盖体214处于打开状态时与断电开关2124断开接触，使断电开关2124断开，清洗机100立刻停止工作；如此设置，可以保障用户的安全，防止在盖体214处于打开状态时，有人伸手到电池包腔体213内接触到带电体而产生人身伤害。
优选的，第一压块2143呈三角形状突出设置在翻转转轴2141上，断电开关2124为微动开关，第二压块2144设有与微动开关2124相抵接的抵接面(未标号)，使得第二压块2144与微动开关2124呈面接触，接触稳定性更好。
如图7至图11并结合图3所示，电机泵组件22包括无刷电机221、与无刷电机221相连的泵头组件222以及连接在无刷电机221两端的第一进水管路223和第二进水管路224，其中，所述无刷电机221设置在所述泵头组件222和所述驱动组件24之间并分别连接所述泵头组件222和所述驱动组件24，所述泵头组件222用于接收外部水源的输入，所述无刷电机221用于向所述泵头组件222提供动力并通过做功使得所述泵头组件222增压，所述驱动组件24用于驱动所述无刷电机221进行工作；第一进水管路223远离泵头组件222设置，以连接外部水源；第二进水管路224在无刷电机221的靠近泵头组件222一侧将无刷电机221与泵头组件222相连。
第一进水管路223包括第一进水接头2231、第一进水软管2232、第二进水接头2233及第三进水接头2234，第一进水软管2232的两端分别通过管箍2235与第一进水接头2231和第二进水接头2233的卡位端抱紧连接，第二进水接头2233与第三进水接头2234通过U形卡销连接，第三进水接头2234与无刷电机221的外壳2211通过螺纹密封连接。如此设计，可以通过进水端的软连接，使清洗机100整机的进水口可以任意布设于壳体组件21的适当 位置。第二进水管路224包括第四进水接头2241、第二进水软管2242及进水管2243，第二进水软管2242的两端也分别通过管箍2244与第四进水接头2241和进水管2243连接，第四进水接头2241与泵头组件222的进水口2221相连通。
驱动组件24包括收容在下壳体211内的水冷驱动器241、位于壳体组件21下方的电路控制器242以及对电路控制器242进行保护的控制器罩壳243，水冷驱动器241在下壳体211内与电机泵组件22电性连接，以驱动电机泵组件22工作；电路控制器242与电池包组件23电性连接，以接入各电池包231的电源并分配给水冷驱动器241；控制器罩壳243设置在下壳体211的底部外侧，电路控制器242收容在控制器罩壳243内，能够将多个电池包231与电源开关2121进行信号集合整理，对直流电源进行供电分配，以输送给水冷驱动器241和无刷电机221，使无刷电机221按照预定的工作程序进行工作。
水冷驱动器241在第一进水管路223一侧与无刷电机221电性连接，无刷电机221内部形成有冷却通道，该冷却通道同时流经水冷驱动器241和无刷电机221，以便外部水源经第一进水管路223进入后先从冷却通道通过，再从第二进水管路224流入泵头组件222，继而带走水冷驱动器241和无刷电机221工作过程中产生的热量，起到了散热的作用。
冷却通道包括形成在水冷驱动器241与无刷电机221之间的第一冷却通道244和位于无刷电机221内部的第二冷却通道245，本实施例中，所述第一冷却通道244设置在所述外壳2211的轴向侧面，且第一冷却通道244呈螺旋状设置，第二冷却通道245呈环状设置，且第二冷却通道245将第一冷却通道244和第二进水管路224连通。如此，在外部水源经过第一冷却通道244和第二冷却通道245对水冷驱动器241上的散热片2411和无刷电机221进行冷却后，便可通过第二进水管路224进入泵头组件222，再经过泵头组件222不断的抽吸、增压输出，最终通过高压大流量的出水喷射到清洁表面，完成清洗工作。所述无刷电机221朝向所述电机泵组件22的一侧为输出端，所述无刷电机221轴向的另一端即为后端，所述散热片2411贴合所述外壳2211固定设置，且所述散热片2411设置在所述水冷驱动器241上。
当无刷电机221运转起来时，泵头组件222通过泵的抽吸作用使外部水源先通过第一进水管路223进入到位于无刷电机221的外壳2211与散热片2411之间的第一冷却通道244，然后再进入到位于无刷电机221的外壳2211与电机罩2212之间的第二冷却通道245，接着再进入到第二进水管路224进入到泵头组件222的进水口2221，再通过高压水泵增压后从泵头组件222的出水端输出到高压水管44、枪杆组件42、喷嘴43，最终通过高压大流量的出水喷射到清洁表面，完成清洗工作。
在电机泵组件22工作的过程中，水冷驱动器241的线路板2412上的MOS管工作时会产生热量传导到与之紧密贴靠的散热片2411上，无刷电机221的线圈也会产生大量的热量并传导到与之紧密贴靠的外壳2211上，当外部水源在持续的通过以上的第一冷却通道244和第二冷却通道245时，便可同步的对水冷驱动器241的散热片2411、外壳2211等进行水 冷却，以消除水冷驱动器241上的MOS管等发热元件、无刷电机221的线圈等在运行时所产生的热量，使动力头组件20能够安全、持续、高效的工作。
如图13至图19所示，为电机泵组件22的另一实施例。在该实施例中，所述无刷电机221包括外壳2211、前端盖22111、定子组件22112、转子组件22113和电机轴22114，其中，所述定子组件22112、所述转子组件22113和所述电机轴22114均收容在所述外壳2211内部。所述第一冷却通道244围设以形成一平面状结构，该平面状结构垂直于所述电机轴22114的延伸方向。所述第一冷却通道244具有入水口2441和出水口2442，所述第一冷却通道244的入水口2441和出水口2442均沿平面状结构的径向设置。当外部水源自所述第一冷却通道244的入水口2441流入后，外部水源将充满所述第一冷却通道244，所述散热片2411和所述外壳2211上的热量将继续传导至所述第一冷却通道244中的水源中，并随着外部水源的不断流动而从所述第一冷却通道244的出水口2442排出，以此带走所述水冷驱动器241和所述无刷电机221在工作过程中产生的热量，起到了散热的作用。所述第一冷却通道244的出水口2442输出的水源可以输入至所述泵头组件222并再次进行利用。
所述第二进水管路224与所述转子组件22113的轴向延伸方向平行，且所述第二进水管路224分别连接所述泵头组件222和所述第一冷却通道244，即，所述第二进水管路224的进水口与所述第一冷却通道244的出水口2442相连通，所述第二进水管路224的出水口与所述泵头组件222相连通。
所述外壳2211与所述驱动组件24连接，所述前端盖22111与所述泵头组件222连接，且所述外壳2211和所述前端盖22111之间为密封连接。所述电机轴22114分别穿过所述外壳2211和所述前端盖22111的旋转中心，所述定子组件22112固定设置在所述外壳2211内壁，所述转子组件22113套设在所述电机轴22114的外周。
较佳地，所述外壳2211密封设置，且所述外壳2211与所述前端盖22111之间形成有容置空间，所述定子组件22112、所述转子组件22113和所述电机轴22114均收容在所述容置空间中。所述容置空间内还设有绝缘液22115，所述绝缘液22115优选为油，且所述绝缘液22115的体积占所述容置空间的体积的95％及以上，以便绝缘液22115可以迅速带走线圈所产生的热量。
当所述电机泵组件22运转时，由于定子组件22112的线圈全部都浸泡在绝缘液22115中，线圈所产生的热量可以充分的被绝缘液22115所带走，同时绝缘液22115与外壳2211充分接触，绝缘液22115的热量也被充分的传导到外壳2211的表面，传导到外壳2211上的热量再被与其构成密封的第一冷却通道244的外部进水源带走，如此便可以有效降低线圈的温度。
本实施例中，所述电机轴22114穿过所述前端盖22111设置，且所述电机轴22114和所述前端盖22111之间设有旋转油封22116，所述旋转油封22116优选设有两个，其中一个靠近所述外壳2211设置，另一个靠近所述泵头组件222设置。所述电机轴22114、所述旋转 油封22116和所述前端盖22111之间形成有密闭腔，所述前端盖22111的外壁上开设有与所述密闭腔连通的排泄孔22117，所述排泄孔22117沿所述电机轴22114的径向延伸。
当所述电机泵组件22运转时，所述前端盖22111的前端油缸内的润滑油可能会渗透到密闭腔内、所述容置空间内的绝缘液22115也可能会渗透到密闭腔内。当前后端渗透进来的油液不能及时排除时，所述密闭腔内的压力会变高，使进入到密闭腔内的油液进入到容置空间内，造成绝缘液22115的污染，使无刷电机221失效或产生其他故障。排泄孔22117的设置，可以将渗入到密封腔内的油液进行有效排出。
如图18所示，所述前端盖22111的外侧壁上设有密封块22119，所述定子组件22112的导线22118经过密封块22119上的穿线孔后与密封块22119形成密封，密封块22119同时与前端盖22111形成密封，如此，可以使得所述无刷电机221的内部空间完全密封。
对于无刷电机221的出线及密封方式，也可以采用其它的结构。比如：设计一个塑料的接线盒，在接线盒内部设计多个双头螺纹结构的接线柱，并且在接线盒内注入阻燃聚氨脂灌封胶，对接线盒两边实现完全的密封；在接线盒外围套上密封圈与外壳进行机械密封；从线圈上引出的导线在接线盒的内侧与接线柱以螺钉连接；在接线盒外侧的接线柱用连接导线分别与其他结构对接。此种连接方式易操作，连接、密封方式更加可靠。如此设计，可以有效避免绝缘液22115从线圈引出的连接导线的芯线之间向外渗漏的情况。
结合图13、图16和图17所示，所述无刷电机221还包括排气阀2213，所述排气阀2213设置在所述外壳2211上且所述外壳2211具有安装所述排气阀2213的阀口，所述排气阀2213与所述容置空间相连通。
所述排气阀2213包括阀体22131、第一密封圈22132、第二密封圈22133、钢球22134和弹性件22135，所述阀体22131嵌入设置在所述阀口中，所述阀体22131的顶部开设有排气孔22136，该排气孔22136与外界空气连通；所述第一密封圈22132套设在所述阀体22131的外侧，以密封连接所述阀体22131和所述外壳2211；所述钢球22134设置在所述阀体22131内部，所述第二密封圈22133位于所述钢球22134和所述阀体22131之间，以密封所述阀体22131的内部空间；所述弹性件22135沿所述排气阀2213的出气方向与所述钢球22134抵接，所述弹性件22135优选为弹簧。排气时，气体推动所述钢球22134在所述阀体22131内朝向排气孔22136移动，使得所述弹性件22135被压缩；排气完成后，所述弹性件22135在自身弹性力的作用下推动所述钢球22134复位，对所述排气阀2213进行封闭。
更具体地，所述电机泵组件22在工作过程中，所述容置空间内的空气在受热膨胀以后，气压会增高，当气体压力达到弹性件22135的预紧力及钢球22134的重量之和时，受压空气便会顶开所述钢球22134，从所述阀体22131上的排气孔22136溢出，从而降低所述容置空间内的压力，以保证密封安全。
如图20-27并结合图13所示，所述泵头组件222包括泵头226、射流释放装置及关枪停机开关2222，所述泵头226用于接受自第二进水管路224流入的清水并进行增压。所述 关枪停机开关2222在用户未启动所述清洗机100时，所述泵头226上的溢流阀杆(未图示)会顶住所述关枪停机开关2222，使其闭合；当用户开启清洗机100正常工作时，所述溢流阀杆一直处于闭合状态，而当用户停止工作并松开扳机时，所述溢流阀杆会脱离与所述关枪停机开关2222的接触而断电停机。
所述泵头226内设有进水流道2261、出水流道2262和加压机构2263，所述加压机构2263位于所述进水流道2261和所述出水流道2262之间，用于将所述进水流道2261内的流体加压后输送至所述出水流道2262，所述出水流道2262内设有单向阀22621。图23、24中的直线箭头所示方向为泵头226正常工作状态下的水流方向，本实施例中，加压机构2263为往复运动的柱塞；图23中，柱塞通过向左的运动将进水流道2261中的流体抽吸至柱塞腔内，然后通过向右的运动将流体挤压至出水流道2262，此过程中柱塞腔的进水口和出水口分别设有一个单向截止阀，单向截止阀与单向阀22621的位置和功能应当加以区分，单向截止阀是为了避免流体在柱塞往复运动过程中产生回流，而单向阀22621则能够防止射流释放装置中的高压流体向泵头226内回流。
可以理解的是，所述射流释放装置可以是喷枪以及与喷枪连接的管道，所述射流释放装置与所述出水流道2262连通；所述射流释放装置具有能够开启或闭合的喷头，当喷头开启时，出水流道2262内的流体能够从射流释放装置排出，从而使出水流道2262保持相对恒定的压力，而当喷头关闭时，出水流道2262内的流体无处释放，因此压力会逐渐升高。
所述关枪停机开关2222包括关枪停机卸荷阀，所述关枪停机卸荷阀包括阀体227和开关单元228，所述阀体227与所述出水流道2262连通，并与所述开关单元228联动配合，所述阀体227被装配为当所述出水流道2262因所述射流释放装置的关闭而导致压力升高时，所述阀体227能够驱动所述开关单元228断开，以关停所述清洗机100，且当所述出水流道2262因所述射流释放装置的开启而导致压力降低时，所述阀体227能够驱动所述开关单元228闭合，以启动所述清洗机100。
所述阀体227包括阀套2271、阀杆2272和第一弹性单元2273，阀套2271可以由多个管状物拼接而成，各管状物之间可以采用焊接、螺纹连接等方式固定，或采用定位销固定。所述定位销包括第一U型销201，其中一个管状物上设有两平行的插孔，另一管状物上设置限位槽，两管状物插合以后再将第一U型销201插置于插孔内，此时第一U型销201被容置在限位槽中，进而阻止两个管状物相互分离，这种连接方式易于安装和拆卸，方便对清洗机100进行检修和维护。
同样的，所述阀套2271与泵头226之间也可以通过定位销来固定，例如在泵头226上设置供第二U型销229插入的销孔，并在阀套2271外壁上设置插槽，当阀套2271安装在泵头226上后，第二U型销229插入销孔内，此时第二U型销229刚好置于插槽中，进而限制阀套2271与泵头226之间的相对位移。
所述阀杆2272相对于阀套2271活动设置在第一工位和第二工位之间；第一弹性单元 2273被装配为其弹力作用在所述阀杆2272与所述阀套2271之间，并使所述阀杆2272保持在所述第一工位；所述阀杆2272与所述阀套2271之间形成有液压腔2274，所述阀套2271上设有贯通至所述液压腔2274的第一通流孔22711，第一通流孔22711外侧通过一内部流道101与出水流道2262连通，当所述液压腔2274内的流体介质达到预设压力时，能够使所述阀杆2272克服所述第一弹性单元2273的弹力并运动至所述第二工位；所述第一通流孔22711与所述单向阀22621下游的所述出水流道2262连通；所述开关单元228具有一触发部，所述触发部被配置为能够被所述阀杆2272触发，且当所述阀杆2272在所述第一工位和所述第二工位之间切换时，能够使所述触发部改变所述开关单元228的开闭状态。
在一具体实施例中，所述开关单元228包括微动开关，所述触发部包括所述微动开关的驱动杆2281，所述阀杆2272与所述驱动杆2281抵接。所述驱动杆2281和所述阀杆2272被装配为当所述阀杆2272位于所述第一工位时，所述微动开关闭合，且当所述阀杆2272位于所述第二工位时，所述微动开关断开。
如图23、26所示，所述阀套2271上开设有第二通流孔22712和第三通流孔22713；所述阀套2271内部设有位于所述第二通流孔22712和所述第三通流孔22713之间的卸荷阀芯2275；所述卸荷阀芯2275与所述阀杆2272联动设置，当所述阀杆2272位于所述第一工位时，所述卸荷阀芯2275保持在闭合状态，且当所述阀杆2272自所述第一工位向所述第二工位运动时，能够将所述卸荷阀芯2275切换为开启状态；所述第二通流孔22712与所述进水流道2261连通，所述第三通流孔22713与所述单向阀22621上游的出水流道2262连通。
可以理解的是，当阀杆2272将开关单元228断开的同时，能够使卸荷阀芯2275开启，此时出水流道2262上游与进水流道2261连通，实现对出水流道2262上游的泄压，这样在清洗机100停机时能够使泵头226处于低压环境中，避免高压对密封元件造成的损耗，提高使用寿命。
如图23所示，所述阀套2271内壁上设有一环槽22714，所述第二通流孔22712和所述第三通流孔22713分别位于所述环槽22714的两端，所述卸荷阀芯2275位于所述环槽22714内。所述卸荷阀芯2275远离所述阀杆2272的一侧设有第二弹性单元2276，所述第二弹性单元2276被配置为其弹力能够驱动所述卸荷阀芯2275紧贴所述环槽22714的靠近所述阀杆2272一侧的槽壁，以阻断所述第二通流孔22712和所述第三通流孔22713之间的流道。所述阀杆2272上朝向所述卸荷阀芯2275的一端设有阀针2277，当所述阀杆2272自所述第一工位向所述第二工位移动时，所述阀针2277能够驱动所述卸荷阀芯2275与所述环槽22714的槽壁分离，以连通所述第二通流孔22712和所述第三通流孔22713之间的流道。在一具体实施例中，所述阀针2277可以沿轴线方向与所述阀杆2272活动连接，所述阀针2277与所述阀杆2272之间设有第三弹性单元2278，以便对卸荷阀芯2275进行缓冲。所述卸荷阀芯2275可以是钢球。
如图26所示，在一具体实施例中，还包括调压螺母2279，所述调压螺母2279与所述 阀杆2272螺纹连接，所述第一弹性单元2273包括设置在所述阀套2271与所述调压螺母2279之间的压簧。可以理解的是，本实施例中，可以通过改变调压螺母2279的旋入深度，来调整第一弹性单元2273的预紧力大小，进而调节触发微动开关所需的压力的大小。
结合上述描述，所述泵头组件222的工作原理为：当喷枪关闭时，出水流道2262下游压力升高，进而驱动阀体227动作，阀体227带动开关单元228动作，开关单元228将电路断开，从而使清洗机100停机，由于单向阀22621的存在，即使清洗机100停机，出水流道2262下游依然能够保持在高压状态，进而使开关单元228保持断开状态；而当喷枪再次开启后，首先将出水流道2262下游的压力释放，此时阀体227和开关单元228复位，电路再次导通，清洗机100启动。
如图12所示，展现了动力头组件20内部各电气元器件的安装位置与方式，本申请中，以4个80V的电池包231作为设计基础，为了保证清洗机100的续航时间，在电机泵组件22上设置有关枪停机开关(Pump switch)，该开关在用户未启动清洗机100时，泵头上的溢流阀杆(未图示)会顶住该开关，使其闭合，当用户开启清洗机100正常工作时，溢流阀杆一直处于闭合状态，而当用户停止工作并松开高压水枪的扳机时，溢流阀杆会脱离与该开关的接触而断电停机。
如图28至图35所示，为电机泵组件22的第三实施例。在该实施例中，采用无刷电机221和驱动组件24进一步提升无刷电机221的额定功率、使电机泵组件22工作时能输出更高的压力与流量，并通过驱动组件24对电机泵组件22在不同使用工况下的运行状态进行调整，以提高用户的使用体验。本申请的无刷电机221可以在驱动组件24设定的恒功率状态下工作，当电机泵组件22在切换使用不同口径大小的喷嘴工作时，可以通过驱动组件24对无刷电机221转速的控制来实现电机泵组件22压力与流量的互补变化，以维持整体负载功率在设定的恒功率状态下工作。
所述无刷电机221的外壳2211上沿周向形成有一环形凸出部2214，所述环形凸出部2214上开设有一凹槽2215，所述环形凸出部2214的外侧设有一环形的罩壳2216，所述罩壳2216将所述凹槽2215的槽口封闭，以形成所述第二冷却通道245。本实施例中，所述罩壳2216与所述环形凸出部2214之间可以采取相应的密封措施，例如在所述罩壳2216与所述环形凸出部2214之间设置密封圈。为了方便罩壳2216与环形凸出部2214之间的连接，所述罩壳2216的一端可以设置相应的凸缘，该凸缘可以通过螺栓与所述环形凸出部2214的侧壁连接。
如图30、31所示，所述驱动组件24设置于所述无刷电机221轴向的一端，所述第一冷却通道244紧贴所述散热片2411设置。优选的，所述散热片2411应当与驱动组件24上的发热元件(如MOS管)尽可能的接触，以提高散热效率。
如图30-34所示，所述第一冷却通道244沿所述散热片2411的表面呈螺旋状布置。具体的，所述外壳2211上设有一螺旋槽2217，所述螺旋槽2217由所述散热片2411封闭以形 成所述第一冷却通道244。可以理解的，本申请的第一冷却通道244也可以采用其它布置方式，只要能够让第一冷却通道244在所述散热片2411上尽可能均匀分布即可，例如将所述第一冷却通道244呈连续的S形布置。
本实施例中，在所述散热片2411的表面布置有与螺旋状的第一冷却通道244走向相同的螺旋形流道2413。此两流道工作时，可以将传递到散热片2411表面的热量尽可能的带走，进一步的提升了冷却效率。可以理解的，本申请的第一冷却通道244尽可能近的贴近发热元件的位置，其位置不一定位于散热片2411的几何中心，可以是以偏心的位置来布置。
所述第二冷却通道245的一端与进水接头50连通、另一端与第一冷却通道244的一端连通，所述第一冷却通道244的另一端与泵头组件222的进水口2221连通。所述无刷电机221的轴线水平设置，所述进水接头50与所述第二冷却通道245的下端连通，所述第二冷却通道245的上端与所述第一冷却通道244连通。本实施例中，所述第二冷却通道245与所述第一冷却通道244依次串联，工作液先经过所述第二冷却通道245，然后经过所述第一冷却通道244。
可以理解的是，第二冷却通道245的进水口位于下方，出水口位于上方，冷却水由下至上填满环形水腔，可将空腔中的空气完全排空。因此在电机泵组件22工作时，不会因流道内的残留空气导致泵的振动，有利于在电机泵组件22自吸水工作状态下，尽快排空流道内的空气，使机器能快速的稳定工作。
如图32、33、35所示，所述进水口2221安装有转接头60，所述转接头60具有第一接口61、第二接口62、第三接口63和第四接口64，其中所述第一接口61和所述第三接口63从所述转接头60的内部连通，所述第二接口62和所述第四接口64从所述转接头60的内部连通；所述进水接头50安装于所述第一接口61；所述第三接口63通过第一管道与所述第二冷却通道245的下端连通，所述第二接口62与所述进水口2221连通，所述第四接口64通过第二管道与所述第一冷却通道244连通。转接头60内部设计成两条独立的隔离水道，分别为进水水道和回水水道，进水水道和回水水道分别与外部水源和泵头组件222连接，水源从进水水道进入到无刷电机221与驱动组件24及连接管路的冷却系统后再回到回水水道注入泵头组件222。
可以理解的是，本申请在进水口2221设置转接头60，电机泵组件22在使用过程中，其安装习惯与现有电机泵组件的安装习惯一致，用户不需要因为水道的改变而付出额外的学习成本，进一步提升了用户的使用体验。
如图30-32所示，所述第一管道包括第一软管431和第一管接头49，所述第一管接头49安装在所述第二冷却通道245的下端，所述第一软管431连接在所述第一管接头49与所述第二接口62之间。所述第二管道包括第二软管441和第二管接头45，所述第二管接头45安装于所述无刷电机221上端，所述第二管接头45的一端通过开设于所述无刷电机221后端的第一径向孔46与所述第一冷却通道244连通，所述第二软管441连接于所述第二管接 头45与所述第四接口64之间。
