具体实施方式
下面详细描述本实用新型的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本实用新型，而不能理解为对本实用新型的限制。
下面参考图1-图7描述根据本实用新型实施例的清洗机1000的主机组件100。
根据本实用新型实施例的主机组件100包括：壳体组件10、泵、电机50。
壳体组件10内具有安装腔11，泵包括泵体20，泵体20位于安装腔11内，电机50与泵体20固定相连，以驱动泵体20，电机50包括电机壳体30。
如图2所示，壳体组件10包括：沿泵体20、电机50排布方向分布的第一壳体14和第二壳体15，第一壳体14与第二壳体15连接，而且第一壳体14和第二壳体15限定出安装腔11，泵和电机50均位于安装腔11内，泵体20和电机壳体30中的至少一个与第一壳体14和第二壳体15中的至少一个固定连接。
电机50与泵体20固定相连，当通过将泵体20和电机壳体30中的一个与壳体组件10固定时，另一个也相对壳体组件10固定。
可以理解的是，泵体20、电机壳体30与壳体组件10的配合方式为多种，如：泵体20与第一壳体14固定连接；泵体20与第二壳体15固定连接；电机壳体30与第一壳体14固定连接；电机壳体30与第二壳体15固定连接；泵体20和电机壳体30均与第一壳体14固定连接；泵体20和电机壳体30均与第二壳体15固定连接；泵体20与第一壳体14固定连接，同时电机壳体30与第二壳体15固定连接等。泵体20、电机壳体30与壳体组件10的连接配合方式并不限于此，可以根据泵体20、电机50在安装腔11内的排布方式进行合理地调节。
当泵体20和电机壳体30中的一个与壳体组件10固定连接时，泵体20和电机壳体30均相对壳体组件10固定，从而将泵和电机50可靠地固定在壳体组件10内。
需要说明的是，主机组件100应用于清洗机1000，主机组件100用于泵送液体，并在泵的作用下泵送出主机组件100。壳体组件10具有进液口18和出液口19，进液口18形成在第二壳体15上，出液口19形成在第一壳体14上，进液口18和出液口19之间具有流体腔室101，液体可以由进液口18进入流体腔室101从出液口19流出。至少部分流体腔室101围绕电机壳体30设置，从而能够在运行过程中，带走电机的热量，为电机散热。至少部分流体腔室101位于泵、电机50排布的方向上，以使至少部分流体腔室101、泵、电机50依次排布。本申请，至少部分流体腔室101位于电机50背离泵端部的一侧，沿泵、电机排布的方向上，依次排布有部分流体腔室101、电机壳体30、泵。当液体进入壳体组件10时，液体进入流体腔室101时，对电机壳体50产生沿泵和电机的排布方向的冲击，由于第一壳体14和第二壳体15沿泵体20和电机50的排布方向分布，从而冲击可以传递到第一壳体14、第二壳体15上使第一壳体14和第二壳体15之间的固定连接结构产生松动，严重的使第一壳体14和第二壳体15爆裂分离。另一方面，泵在运行过程中，泵的柱塞运动，也容易冲击到第一壳体和第二壳体上，使两者之间出现松动或者爆裂的情况。
而本申请将泵体20和电机壳体30与壳体组件10固定连接，确保泵体20和电机壳体30与壳体组件10的可靠性，抵抗冲击力的能力强，从而提升主机组件100中多个部件之间的连接可靠性，同时还可以保证主机组件100工作时的稳定性。
根据本实用新型实施例的主机组件100，泵和电机50与壳体组件10之间的连接可靠性高，抵抗液体的冲击力的能力强，可以有效地防止多个部件之间相对晃动，提升主机组件100运行时的稳定性和可靠性。
在本实用新型的一些实施例中，如图2所示，泵体20临近出液口19设置，电机壳体30临近进液口18设置，当液体进入流体腔室101时，液体流经电机壳体30。需要说 明的是，电机壳体30内设置有电机50，电机50运行时将会产生一定的热量，热量可以传递至电机壳体30，并由电机壳体30传递至进入流体腔室101内的液体，液体在流体腔室101内由泵体20泵送至出液口19。由此，当液体由进液口18进入流体腔室101时，液体可以与电机壳体30接触，并对电机50进行冷却，提高电机50效率，降低电机50的额外功率消耗。
可以理解的是，进入流体腔室101内的液体由泵体20泵送出流体腔室101后，可以用于清洗物体，液体可以为水或具有清洗功能的液体，在液体流入流体腔室101并与电机壳体30接触时，电机壳体30的热量可以传递至液体，从而液体还具有冷却电机50的功能，而且液体在流体腔室101内是流动的，流动的液体对电机50的冷却效果好、冷却效率高。
如图7所示，进液口18设置于第二壳体15的侧壁，贯穿第二壳体15的侧壁与流体腔室101连通，液体可以由进液口18进入流体腔室101。进液口18还可以设置在第二壳体15远离所述第一壳体14的端面上，液体可以由进液口18进入流体腔室101。
在本实用新型的一些实施例中，第一壳体14和第二壳体15均呈筒状，第一壳体14与第二壳体15插接配合，并通过螺纹紧固件固定连接。由此，第一壳体14和第二壳体15通过插接配合定位，并通过螺纹紧固件连接固定。第一壳体14和第二壳体15的配合难度小，而且筒状的结构可以保证第一壳体14和第二壳体15限定出安装腔11的空间充足，以满足泵体20和电机50的布置需求。
更进一步地，第一壳体14的边缘具有第一插接部，第二壳体15的边缘具有第二插接部，第一插接部与第二插接部插接，第一插接部和第二插接部中的一个为凹槽，另一个为凸缘，从而通过第一插接部和第二插接部插接配合可以将第一壳体14与第二壳体15定位。
在凹槽内设有密封件。当凸缘与凹槽插接配合时，凸缘可以止抵在密封件上，从而可以提升第一壳体14和第二壳体15之间的密封性。
在本实用新型的一些实施例中，壳体组件10还包括紧固件，泵体20和电机壳体30中的至少一个通过紧固件与第一壳体14和第二壳体15中的至少一个固定。通过紧固件将泵体20、电机壳体30与壳体组件10固定连接的方式可靠性高。
可选地，紧固件位于泵体20和第一壳体14之间，以将泵体20和第一壳体14固定连接。电机50与泵体20固定连接，第一壳体14与第二壳体15固定连接，由此将泵体20、电机50、第一壳体14以及第二壳体15固定连接，连接可靠性高。冲击从电机50传递到泵体20、第一壳体14后，较难传递到第二壳体15上，从而保障第一壳体14和 第二壳体15之间的固定连接。
在本实用新型的另一些实施例中，电机壳体30形成有自外周壁朝向壳体组件10的内壁面凸出的连接凸耳32，壳体组件10形成有连接凸耳32对应的连接凸台13，紧固件可以穿过连接凸耳32与连接凸台13配合，以将电机壳体30与壳体组件10固定。
如图5所示，具体地，连接凸耳32设置在电机壳体30临近泵体20的一端，且朝向第二壳体15的周壁的一侧延伸，连接凸台13形成在第二壳体15临近第一壳体14的一侧并与连接凸耳32对应。连接凸耳32搭接连接凸台13，固定件可以穿过连接凸耳32与连接凸台13连接配合，以将电机壳体30与第二壳体15固定连接。
如图2、3所示，可选地，壳体组件10形成有自内壁面向内延伸进入流体腔室101的安装部102，安装部102具有沿厚度方向贯穿的多个安装位，电机壳体30上具有与安装位对应的配合孔33，紧固件可以穿过安装位与配合孔33配合以将电机壳体30与壳体组件10固定。
具体地，参照图2，安装部102由第二壳体15的内壁面向内延伸，而且安装部102与电机50在上下方向的正投影的至少一部分对应，电机壳体30上的配合孔33设置在与安装部102对应的区域内。在电机壳体30与第二壳体15的装配过程中，电机壳体30止抵在安装部102上，而且配合孔33与安装位对应，紧固件可以穿过安装位与配合孔33配合，从而将电机壳体30与第二壳体15固定连接。
紧固件可以为螺栓40，配合孔33内设置有与螺栓40螺纹配合的螺纹，紧固件与配合孔33螺纹配合以将安装部102与第二壳体15紧固配合，以提升第二壳体15和电机壳体30之间的配合可靠性，防止电机壳体30与第二壳体15的连接在液体冲击力的作用下而松动的问题发生。且冲击主要传递到电机、泵体20上，减少对第一壳体14的冲击，保障第一壳体14和第二壳体15之间的固定连接。
可选地，安装位和配合孔33均为多个，而且多个安装位沿安装部102的周向方向间隔排布，配合孔33与安装位一一对应，从而可以提升第二壳体15与电机壳体30的连接可靠性。
进一步地，安装部102可以构造为环状结构，从而安装部102可以对电机50进行稳定支撑，而且进入流体腔室101的液体可以经环状结构的过孔与电机壳体30接触，以对电机50冷却。
如图4所示，电机壳体30的部分外表面具有外螺纹31，第二壳体15的内避免具有与外螺纹31相适配的内螺纹12，内螺纹12与外螺纹31螺纹配合，以将电机壳体30与第二壳体15连接固定，而且螺纹配合的方式可靠性高，当进入流体腔室101的液体 冲击电机壳体30时，可以有效地防止电机壳体30相对第二壳体15脱出的问题发生。且冲击主要传递到电机、泵体20上，减少对第一壳体14的冲击，保障第一壳体14和第二壳体15之间的固定连接。
在本实用新型的一些实施例中，壳体组件10具有支撑脚16和定位筋17，支撑脚16和定位筋17夹持泵体20和电机壳体30中的至少一个，以将泵体20、电机50固定在第一壳体14和第二壳体15之间。
可以理解的是，支撑脚16和定位筋17可以对泵体20或电机壳体30单独夹持固定，还可以同时对泵体20和电机壳体30加持固定，从而可以根据不同的设计需求对支撑脚16和定位筋17的位置调节，以将泵和电机50固定在第一壳体14和第二壳体15之间。
进一步地，支撑脚16设置在第二壳体15上，支撑脚16可以止抵电机50壳的底部，定位筋17设置在第一壳体14上，定位筋17可以抵接泵体20，以将泵体20和电机壳体30夹持在支撑脚16和定位筋17之间。通过定位筋17和支撑脚16对泵体20和电机50壳的位置定位，防止电机50和泵体20相对壳体组件10运动，提升电机50、泵体20与第一壳体14、第二壳体15之间的配合可靠性。
如图6所示，支撑脚16为多个，多个支撑脚16在第二壳体15的内周壁的周向方向间隔排布，多个支撑脚16的设置可以提升支撑脚16与电机壳体30配合时的稳定性，合理地增加支撑脚16与电机壳体30的接触面积，从而对电机壳体30限位。在任意两个相邻的支撑脚16之间留有一定的间隙，进入流体腔室101内的液体可以通过间隙与电机壳体30接触，可以增加电机壳体30与液体的接触面积。
主机组件100还包括多个密封圈，其中部分密封圈布置电机壳体30的径向方向的外周面上，并夹持在电机壳体30和第二壳体15之间，从而可以保证第二壳体15和电机壳体30之间的密封性，同时可以对安装腔11和流体腔室101的空间分隔，，防止液体进入电机壳体30，提高主机组件100的安全性。另一部分密封圈可以根据设计需求布置在进液口18等位置，以提升主机组件100的密封性。
根据本实用新型实施例的主机组件100，主机组件100可以通过水冷的方式对电机壳体30进行冷却，可以降低电机50的额外功率消耗，提高电机50效率，而且壳体组件10与其内部的电机壳体30、泵体20的连接可靠性高。其中，进液口18可以沿壳体组件10的径向方向设置，由此可以缓解进入流体腔室101的液体的冲击力，防止多个部件之间的连接松动，提升主机组件100的可靠性。同时，壳体组件10的密闭效果好，可以有效降低噪音，提高用户的使用舒适性。
根据本实用新型实施例的清洗机1000，包括：喷枪200、连接附件300和上述的主 机组件100，连接附件300连接在喷枪200和主机组件100之间，并分别与喷枪200和主机组件100连通。
具体地，主机组件100内设置有泵体20、电机50，并用于向喷枪200泵送液体，液体在途径主机组件100时对主机组件100内部的电机50冷却以防止电机50的温度过高而增加电机50的额外功率消耗，提高电机50效率，同时泵体20可以将主机组件100内的液体泵送至连接附件300，由连接附件300流向喷枪200。其中，通过水冷的方式对电机50降温，冷却效果好，而且同时可以满足对喷枪200的供水需求。
进一步地，连接附件300为水电一体管，水电一体管可靠性高，可以满足清洗机1000对供水和供电的需求。
