在一个实施例中，请参阅图1、图2、图3与图4，一种手持式清洗机100，包括：壳体110、往复机构120、驱动组件130及水泵组件140。壳体110设有安装腔111。往复机构120设置于安装腔111内，且往复机构120包括往复轴121、套筒122及第一导向组件123。套筒122套设在往复轴121上。往复轴121上设有导向部1211，套筒122通过第一导向组件123与导向部1211导向配合。驱动组件130设置于安装腔111内，驱动组件130与往复轴121驱动连接，驱动组件130用于驱使往复轴121转动，以使得套筒122沿往复轴121的长度方向往复运动。水泵组件140包括进水件141、泵体142及出水件143。泵体142与套筒122连接，且泵体142连通于进水件141与出水件143之间。泵体142沿着往复轴121的轴线运动时用于从进水件141进水，并将水从出水件143排出。
上述手持式清洗机100，在使用过程中，首先，将水管或水罐与进水件141连通；然后，操作驱动组件130，驱使往复轴121转动，由于第一导向组件123与往复轴121上的导向部1211导向配合，套筒122与第一导向组件123连接，使得套筒122往复轴121的转动下沿往复轴121的长度方向往复运动。由于泵体142与套筒122连接，使得泵体142在水泵组件140中进行活塞往复运动， 将水从进水件141中吸入，并从出水件143中排出。本手持式清洗机100，由于采用往复轴121的轴向转动转换为套筒122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123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，进而对手持式清洗机100来说，有利于提高出水的水压与流量，提高手持式清洗机100的使用体验。
其中，驱动组件130与往复轴121驱动连接应理解为，驱动组件130与往复轴121连接，且驱动组件130作为动力，能够驱动往复轴121转动。
需要说明的是，导向部1211通过第一导向组件123与套筒122导向配合应理解为，套筒122通过第一导向组件123与导向部1211抵触配合，如滚动配合、滑动配合等，导向部1211对第一导向组件123起导向作用，使得第一导向组件123沿着导向部1211的轮廓轨迹运动，而套筒122与第一导向组件123相对静止，因此套筒122相对导向部1211运动，由于导向部1211周向设置在导向轴上，因此，导向轴转动使得套筒122往复运动。
其中，为了进一步理解与说明往复轴121的轴线方向，以图1为例，往复轴121的轴线方向为图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123包括第一滚动件1231与连接座1232，第一滚动件1231通过连接座1232与套筒122连接，第一滚动件1231与导向部1211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120的传动效率，进而提高手持式清洗机100的使用品质。
具体地，请参阅图1与图3，第一滚动件1231为滚珠。连接座1232为固定钢球托。连接座1232与套筒螺纹连接。或者，连接座1232通过卡簧固定在套筒122内。如此，有利于提高第一滚动件1231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手持式清洗机100的水压和流量。
又或者是，第一滚动件1231与连接座1232为一体式的万向球轴承。如此，有利于提高第一导向组件123的结构稳定性，在保证负载的情况下万向球轴承与往复轴121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手持式清洗机100的水压和流量。
进一步地，请参阅图1与图2，第一导向组件123为至少两个，至少两个第一导向组件123沿往复轴121的周向间隔设置，且至少两个第一导向组件123均与导向部1211滚动配合。
具体地，请参阅图1与图4，第一导向组件123为两个，两个第一导向组件123沿往复轴121的轴线对称设置。两个第一导向组件123均与导向部1211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123的导向作用，提高往复机构120的传动效率。另一方面，两个对称设置的第一导向组件123有利于提高导向组件对往复轴121周向的支撑作用，避免往复轴121摆动，并相互抵消偏向力，进一步降低功率损耗，使得套筒的运动更加舒畅，降低磨损，进而提高手持式清洗机100的使用品质。
可选地，导向部1211可为导向板1241、导槽、导管或其它导向结构。
具体地，请参阅图1与图4，导向部1211为导向槽，导向槽沿往复轴121的周向延伸设置，且沿往复轴121的轴向往复延伸，第一滚动件1231与导向槽滚动配合。如此，通过第一滚动件1231沿导向槽的轮廓滚动，从而带动套筒122往复运动，有利于提高往复机构120的结构稳定性，同时提高往复机构120的传动效率，降低损耗，进而提高手持式清洗机100的使用可靠性。本实施例仅提供一种导向部1211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1、图2、图3与图4，往复机构120还包括第二导向组件124，第二导向组件124与安装腔111的腔壁连接，第二导向组件124与套筒122导向配合。如此，第二导向组件124有利于对套筒122的往复运动起导向作用，避免套筒122的往复运动在安装腔111内发生大程度的轨迹偏移，有利于减小偏向力，提高传动机构的传动效率，进而提高水泵组件140的运动稳定性，进一步提高手持式清洗机100的使用品质。
进一步地，请参阅图1、图2、图3与图4，第二导向组件124包括导向板1241与第二滚动件1242，导向板1241与安装腔111的腔壁连接，且导向板1241沿往复轴121的长度方向延伸设置，套筒122通过第二滚动件1242与导向板1241导向配合。如此，有利于减小套筒122与导向板1241的摩擦，提高套筒122往复运动的顺畅性，进而提升水泵组件140的工作稳定性与可靠性。
具体地，请参阅图1、图2、图3与图4，第二滚动件1242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120与驱动组件130的传动效率，降低功率损耗，进而提高水泵组件140的使用可靠性。
更进一步地，导向板1241上设有球槽，第二滚动件1242通过球槽与导向板滚动配合。如此，有利于提高第二滚动件1242在导向板1241的顺畅性和导向性，同时还能避免第二滚动件1242掉落，提高第二导向组件124的工作可靠性，进而提升水泵组件140的工作稳定性与可靠性。
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124为至少两个，至少两个第二导向组件124沿套筒122的周向间隔设置，且至少两个第二导向组件124均与套筒122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124为两个，两个第二导向组件124沿套筒122的轴线对侧设置于套筒122周向的相对两侧，且 两个第二导向组件124均与套筒122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124对套筒122往复运动的导向作用与支撑作用，避免套筒122的往复运动发生大程度的轨迹偏移，提高往复机构120的传动效率，进而提高水泵组件140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，泵体142包括柱塞1421、第一单向阀1422、第二单向阀1423及泵身1424，柱塞1421与套筒122连接，第一单向阀1422连通于柱塞1421与进水件141之间，第二单向阀1423连通于柱塞1421与出水件143之间，柱塞1421往复运动时，用于将水从进水件141通过第一单向阀1422与第二单向阀1423从出水件143排出。如此，由于单向阀的单向导通作用，柱塞1421运动时，水只能够从进水件141通过第一单向阀1422吸入到泵身1424中，再通过第二单向阀1423从出水件143中排出，有利于避免水回流，提高水泵组件140的工作可靠性。
在一个实施例中，请参阅图1与图2，泵体142还包括第三单向阀1425与第四单向阀1426，第三单向阀1425连通于柱塞1421与进水件141之间，且第三单向阀1425与第一单向阀1422方向相反。第四单向阀1426连通于柱塞1421与出水件143之间，且第四单向阀1426与第二单向阀1423方向相反。如此，柱塞1421在泵身1424内往复运动时，前进后退都能做功：柱塞1421前进时，通过第一单向阀1422、第二单向阀1423形成吸水和出水，柱塞1421后退时，通过第三单向阀1425与第四单向阀1426形成吸水和出水，柱塞1421往复运动时持续出水，有利于提高水泵组件140的工作效率，进而提高手持式清洗机100的出水品质和使用体验。
在一个实施例中，请参阅图1、图2、图3与图4，驱动组件130包括减速箱131及驱动件132，驱动件132与减速箱131驱动连接，减速箱131与往复轴 121传动连接。驱动件132驱动减速箱131运动，从而带动往复轴121转动，有利于调整往复轴121的转速，进而调整柱塞1421的运动速度，调整水泵组件140的水压与流量，有利于提高手持式清洗机100的稳定性和使用品质。
可选地，驱动件132可为电机、液压马达、气动马达或其它驱动装置。
具体地，请参图1、图2、图3与图4，驱动件132为电机。如此，有利于提高驱动件132的便携性，通过电池驱动便于手持式清洗机100的充电与携带，进而提高手持式清洗机100的使用便利性。本实施例仅提供一种驱动件132的具体实施方式，但并不以此为限。
在一个实施例中，请参图1、图2、图3与图4，所述驱动组件130还包括传动件133，所述减速箱131通过所述传动件133与所述驱动件132传动连接。如此，驱动件132驱动传动件133运动，从而带动减速箱131运动，有利于提高驱动件132的驱动效果和驱动件132的使用寿命，同时不同的传动方式有利于提高安装腔111内部结构的紧凑性，减小体积和重量，进而提高手持式清洗机100的使用品质。

具体地，请参阅图1与图2，传动件133为齿轮。如此，有利于保证往复机构120的传动效率，提高往复轴121的运动稳定性，同时提高安装腔111内部结构的紧凑性，进而降低手持式清洗机100的体积与质量，方便携带，提高手持式清洗机100的使用体验。本实施例仅提供一种传动件133的具体实施方式，但并不以此为限。
在一个实施例中，进水件141设有安全溢流阀(图中未示出)，安全溢流阀连通于进水件141与柱塞1421之间。如此，有利于在水泵组件140中起安全 保护作用，当泵体142内的压力超过规定值时，安全溢流阀顶开，将泵体142出水的水流部分回到进水件141中，使得泵体142内的压力维持在安全值范围内，从而保证水泵组件140不因压力过高而发生事故，有效提高手持式清洗机100的使用安全性和可靠性。
