Description
本发明涉及清洗工具技术领域，特别是涉及一种清洗机往复结构及手持式清洗机。
随着清洗工具技术的发展，出现了手持式清洗机技术，手持式清洗机是一种利用水流压力来清洁物体表面污垢、油垢和沉淀物等脏污的清洁设备，由于其手持使用，方便携带，能够满足户外活动的清洁需求，因而得到了广泛应用。
传统技术中，手持式清洗机采用电机驱动减速箱，带动偏心机构形成往复运动，带动单柱塞在泵体被作往复运动，对水进行做功，形成吸水和出水，从而将水高压喷出，对污垢形成清洗作用。
然而，目前的手持式清洗机，偏心机构带动单柱塞，在泵体内作往复运动时存在巨大偏心力，使得压榨柱塞在泵体内作滑动摩擦，传动效率不高，整体做工效率较低，损耗较大。

在一个实施例中，请参阅图1、图2及图3，一种清洗机往复结构100，包括：往复机构110、水泵组件120及第二导向组件130。往复机构110包括往复 轴111、套筒112及第一导向组件113，套筒112套设在往复轴111上。往复轴111上设有导向部1111，套筒112通过第一导向组件113与导向部1111导向配合。往复轴111用于在驱动组件210的作用下转动，以使套筒112往复运动。水泵组件120包括泵体121与柱塞122，泵体121设有往复腔1211、第一通道1212及第二通道1213，第一通道1212与第二通道1213均与往复腔1211连通。柱塞122与往复腔1211滑动配合，且套筒112与柱塞122连接。柱塞122用于将水从第一通道1212吸入往复腔1211内，并从第二通道1213排出。第二导向组件130包括导轨131与第二滚动件132，导轨131与泵体121连接，且导轨131沿往复轴111的长度方向延伸设置，套筒112通过第二滚动件132与导轨131导向配合。
上述清洗机往复结构100，在组装过程中，首先，将往复轴111通过第一导向组件113与套筒112导向配合；然后，将柱塞122与往复腔1211滑动配合；接着，将柱塞122与套筒112连接；最后，将导轨131与泵体121连接，并使得套筒112通过第二滚动件132与导轨131导向配合。在使用过程中，将往复轴111与驱动组件210连接，操作驱动组件210，驱使往复轴111转动，由于第一导向组件113与往复轴111上的导向部1111导向配合，套筒112与第一导向组件113连接，使得套筒112往复轴111的转动下沿往复轴111的长度方向往复运动。由于柱塞122与套筒112连接，使得柱塞122在往复腔1211内进行活塞往复运动，将水从第一通道1212中吸入，并从第二通道1213中排出。本清洗机往复结构100，由于采用往复轴111的轴向转动转换为套筒112的往复运动，将传统的偏心机构中滑动摩擦改变为第一导向组件113的滚动摩擦，有利于减少偏向力，降低功率损耗，提高传动效率，对泵组件来说，有利于提高出水的水压与流量，提高手持式清洗机200的使用体验。
需要说明的是，套筒112通过第一导向组件113与导向部1111导向配合应理解为，套筒112通过第一导向组件113与导向部1111抵触配合，如滚动配合、滑动配合等，导向部1111对第一导向组件113起导向作用，使得第一导向组件113沿着导向部1111的轮廓轨迹运动，而套筒112与第一导向组件113相对静止，因此套筒112相对导向部1111运动，由于导向部1111周向设置在导向轴上，因此，导向轴转动使得套筒112往复运动。
还需说明的是，套筒112通过所述第二滚动件132与导轨131导向配合应理解为，第二滚动件132与导轨131可为滑动配合、滚动配合或其它配合方式。
其中，为了进一步理解与说明往复轴111的长度方向，以图1为例，往复轴111的长度方向为图1中直线S
1上任意一箭头所指的方向。
在一个实施例中，请参阅图1、图2、图3与图4，第一导向组件113包括第一滚动件1131与连接座1132，第一滚动件1131通过连接座1132与套筒112连接，第一滚动件1131与导向部1111滚动配合。如此，通过滚动配合有利于减少摩擦，降低功率损耗，提高往复机构110的传动效率，进而提高清洗机往复结构100的传动效率。
具体地，请参阅图1与图3，第一滚动件1131为滚珠。连接座1132为固定钢球托。连接座1132与套筒112螺纹连接。或者，连接座1132通过卡簧固定在套筒112内。如此，有利于提高第一滚动件1131的滚动顺畅性，进一步降低功率损耗，提高传动机构的传动效率，进而在相同功率下有利于提高水泵组件120的水压和流量。
又或者是，第一滚动件1131与连接座1132为一体式的万向球轴承。如此，有利于提高第一导向组件113的结构稳定性，在保证负载的情况下万向球轴承与往复轴111形成滚动摩擦，有利于降低功率损耗，提高传动效率，在相同功 率下有利于提高水泵组件120的水压和流量。
进一步地，请参阅图1与图2，第一导向组件113为至少两个，至少两个第一导向组件113沿往复轴111的周向间隔设置，且至少两个第一导向组件113均与导向部1111滚动配合。
具体地，请参阅图1与图3，第一导向组件113为两个，两个第一导向组件113沿往复轴111的轴线对称设置。两个第一导向组件113均与导向部1111滚动配合。但并不以此为限。如此，一方面，有利于提高第一导向组件113的导向作用，提高往复机构110的传动效率。另一方面，两个对称设置的第一导向组件113有利于提高导向组件对往复轴111周向的支撑作用，避免往复轴111摆动，并相互抵消偏向力，进一步降低功率损耗，使得套筒112的运动更加舒畅，降低磨损，进而提高清洗机往复结构100的使用品质。
在一个实施例中，请参阅图1与图2，第一导向组件113还包括固定件114。固定件114套设在套筒112上，且所述固定件114与第一滚动件1131限位配合。如此，固定件114能够夹紧第一滚动件1131，避免第一滚动件1131从套筒112中脱离，提高第一导向组件113的工作可靠性，进而提高清洗机往复结构100的使用品质。
可选地，导向部1111可为导轨131、导槽、导管或其它导向结构。
在一个实施例中，请参阅图1与图2，往复机构还包括往复壳。往复轴、套筒及第一导向组件均设置于往复壳内，往复壳通过导轨与泵体连接。如此，往复机构与水泵组件形成一体式结构，有利于提高结构紧凑性和传递效率，带来更高的水压及更高的流量。
具体地，请参阅图1与图4，导向部1111为导向槽，导向槽沿往复轴111的周向延伸设置，且沿往复轴111的轴向往复延伸，第一滚动件1131与导向槽 滚动配合。如此，通过第一滚动件1131沿导向槽的轮廓滚动，从而带动套筒112往复运动，有利于提高往复机构110的结构稳定性，同时提高往复机构110的传动效率，降低损耗，进而提高手持式清洗机200的使用可靠性。本实施例仅提供一种导向部1111的具体实施方式，但并不以此为限。
具体地，请参阅图1与图2，第二滚动件132为钢珠。如此，滚动方式有利于减小摩擦，降低功率损耗，提高往复机构110与驱动组件210的传动效率，降低功率损耗，进而提高水泵组件120的使用可靠性。
更进一步地，请参阅图1，导轨131上设有球槽，第二滚动件132通过球槽与导轨131滚动配合。如此，有利于提高第二滚动件132在导轨131的顺畅性和导向性，同时还能避免第二滚动件132掉落，提高第二导向组件130的工作可靠性，进而提升水泵组件120的工作稳定性与可靠性。
在另外一个实施例中，请参阅图4，导轨131为两根导柱，第二滚动件132与两根导柱滚动配合。如此，有利于简化导轨131的结构，减小导轨131的体积，提高清洗往复结构的紧凑性，进而有利于提高清洗机往复结构100的使用品质。
在一个实施例中，请参阅图1、图2、图3与图4，第二导向组件130为至少两个，至少两个第二导向组件130沿套筒112的周向间隔设置，且至少两个第二导向组件130均与套筒112滚动配合。
具体地，请参阅图1、图2、图3与图4，第二导向组件130为两个，两个第二导向组件130沿套筒112的轴线对侧设置于套筒112周向的相对两侧，且两个第二导向组件130均与套筒112滚动配合。但并不以此为限。如此，有利于进一步提高第二导向组件130对套筒112往复运动的导向作用与支撑作用，避免套筒112的往复运动发生大程度的轨迹偏移，提高往复机构110的传动效 率，进而提高水泵组件120的工作稳定性与可靠性。
在一个实施例中，请参阅图1与图2，清洗机往复结构100还包括单向阀组140，单向阀组140包括第一单向阀141与第二单向阀142，第一单向阀141连通于第一通道1212与往复腔1211之间，第二单向阀142连通于第二通道1213与往复腔1211之间，且第一单向阀141与第二单向阀142的方向相反。如此，由于单向阀的单向导通作用，柱塞122运动时，水只能够从进水件220通过第一单向阀141吸入到泵身中，再通过第二单向阀142从出水件230中排出，有利于避免水回流，提高水泵组件120的工作可靠性。
在一个实施例中，请参阅图1与图2，泵体还设有第三通道1214与第四通道1215，单向阀组140还包括第三单向阀143与第四单向阀144，第三单向阀143连通于第三通道1214与往复腔1211之间，且第三单向阀143与第一单向阀141方向相反。第四单向阀144连通于第四通道1215与往复腔1211之间，且第四单向阀144与第二单向阀142方向相反。如此，柱塞122在泵身内往复运动时，前进后退都能做功：柱塞122前进时，通过第一单向阀141、第二单向阀142形成吸水和出水，柱塞122后退时，通过第三单向阀143与第四单向阀144形成吸水和出水，柱塞122往复运动时持续出水，有利于提高水泵组件120的工作效率，进而提高手持式清洗机200的出水品质和使用体验。

具体地，请参阅图1与图2，传动件213为齿轮。如此，有利于保证往复机构110的传动效率，提高往复轴111的运动稳定性，同时提高安装腔内部结构的紧凑性，进而降低手持式清洗机200的体积与质量，方便携带，提高手持式清洗机200的使用体验。本实施例仅提供一种传动件213的具体实施方式，但并不以此为限。
在一个实施例中，请参阅图3，手持式清洗机200还包括进水件220与出水件230，进水件220与第一通道1212连通，出水件230与第二通道1213连通。如此，通过进水件220与储水装置或供水装置连接，在水泵组件120的作用下水从进水件220进入到往复腔1211中，并从出水件230排出，有利于提高手持式清洗机200的排水效率。
在一个实施例中，进水件220设有安全溢流阀(图中未示出)，安全溢流阀连通于进水件220与柱塞122之间。如此，有利于在水泵组件120中起安全保护作用，当泵体121内的压力超过规定值时，安全溢流阀顶开，将泵体121出水的水流部分回到进水件220中，使得泵体121内的压力维持在安全值范围内，从而保证水泵组件120不因压力过高而发生事故，有效提高手持式清洗机 200的使用安全性和可靠性。
在一个实施例中，请参阅图1与图2，进水件220设有进水快接头221，所述进水快接头221用于与储水装置可拆卸连接。如此，有利于提高进水件220与进水快接管、水罐等储水装置的连接稳定性，同时便于拆卸，有利于提高储水装置更换的便利性，进而有利于提高手持式清洗机200的使用便利性。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
