在无需交流电源的前提下，为了能够将机身直接置于水中并产生高压水流以供喷枪清洗使用，在本申请中提出了一种清洗机，图1为本发明实施例中清洗机的示意图，图2为本发明实施例中清洗机主机的外观立体图，图3为本发明实施例中清洗机主机的剖面图，图4为本发明实施例中清洗机主机的爆炸图，如图1至图4所示，清洗机可以包括：手持喷枪200，包括喷枪壳体，喷枪壳体上开设有供流体进入的手持喷枪进液口202以及供流体喷出的喷枪出液口203，喷枪壳体提供用以握持的手柄204；主机100，主机100与手持喷枪200分体设置，主机100包括：泵4，泵4用于对流体进行加压；电机5，电机5用于驱动泵4工作；周向包绕在电机5和/或泵4外侧的外壳；第一壳体2；第二壳体3，第二壳体3与第一壳体2接合构成主机壳体，主机壳体内具有收容泵4和电机5的安装腔102；管线8，管线8连接在手持喷枪200和主机100之间，将泵4加压后的流体引导到手持喷枪200的喷枪进液口202；为电机提供能量的电池包201；主机100还包括：主机壳体密封件6，主机壳体密封件6阻断第一壳体2和第二壳体3的接合间隙与安装腔102之间的通路；管线密封机构，管线密封机构阻断管线8与主机壳体的管线装配间隙与安装腔102之间的通路；进水密封机构，主机壳体上具有供流体流入的敞口22，主机壳体内具有与敞口22相连通的进水通道，进水通道与外壳之间具有进水装配间隙，进水密封机构阻挡进水装配间隙与安装腔102之间的通路。
在本申请中清洗机自身直接具有电池包，通过电池包给电机进行供电，从而带动泵运转，这样，用户能够随时随地启动清洗机，无需顾虑周围是否具有交流电电源。
在本实施方式中，主机壳体可以具有直接置于外界水源中的工作模式，此 时，敞口22为流体介质的直接吸入口。当然，清洗机的主机壳体也可以不直接置于外界水源中，通过在敞口处连接软管，将软管的另一端置于外界水源中。
由于主机壳体能够直接置放在水源中吸水，为了防止主机壳体内的器件进水失效，不可避免的需要考虑对主机壳体进行防水保护。
申请人研究发现对于清洗机的主机而言需要重点考虑三处的密封，具体的，该三处具体包括：第一壳体2和第二壳体3的接合间隙与安装腔102之间的通路，管线与主机壳体的管线装配间隙与安装腔102之间的通路以及进水通道和外壳之间的进水装配间隙到安装腔102之间的通路。对上述三处进行充分的密封以提高其密封性能，以使在高水压下也能够阻止水慢慢渗入主机。因此，在本申请中清洗机的主机通过主机壳体密封件对第一壳体2和第二壳体3的接合间隙与安装腔之间的通路进行阻断，通过管线密封机构对自管线与主机壳体的管线装配间隙与安装腔之间的通路进行阻断，同时，通过进水密封机构对进水通道和外壳之间的进水装配间隙到安装腔之间的通路进行阻挡，如此可以有效提升整个主机的密封效果。当将清洗机的主机直接置于水中时可以有效防止水流入至主机壳体内部，将出现泄漏的可能性或渗透的程度降到最低。本申请中清洗机的主机在上述密封结构下的防水等级可以达到IP7，因此能够保证主机长时间浸没在水深达到1米的水下，从而保证清洗机在常见水源中的长时间顺利运行。本申请中清洗机主机的高密封使其适用多种工作场景，可以直接将清洗机主机的主机壳体置于盛水容器中，例如水池、游泳池等蓄水场地，仅操作喷枪就可控制喷水清洗，这样避免了再采用软管将清洗机与水源相连接的麻烦。
为了能够更好的理解本申请中的清洗机，下面将对其做进一步解释和说明。如图3，主机可以包括主机壳体，整个主机壳体具有沿竖直方向延伸的轴线1，在此需要说明的是，在本实施方式中，竖直方向可以理解为管线延伸的方向。主机壳体并非需要沿着轴线1呈完全对称。主机壳体可以包括第一壳体2和第二壳体3，第一壳体2和第二壳体3可以沿轴线1方向排布，即采用上下结构的拼接方式连接。第一壳体2位于第二壳体3的下端，第一壳体2的下端为底 部。第一壳体2与第二壳体3相对的端部呈开口状，第一壳体2的上端呈开口状，第二壳体3的下端呈开口状。当第一壳体2与第二壳体3接合构成主机壳体时，第一壳体2的上端与第二壳体3的下端相密封对合，此时，主机壳体沿轴线1所在平面下的周长大于主机壳体沿垂直于轴线1所在平面下的周长，如此，第一壳体2的端部与第二壳体3的端部相密封的周长最短，第一壳体2和第二壳体3密封处出现泄漏的可能性最低，可以有效保证密封效果，进一步提高密封性能。当清洗机的主机直接置于水中时可以有效防止水流入至主机壳体内部。
在另一种实施方式中，图5为本发明实施例中清洗机的主机壳体在另一种实施方式下的剖面图，如图5所示，第一壳体2和第二壳体3可以沿垂直于轴线1的方向排布，即采用左右结构的拼接方式连接。
如图3和图4所示，泵4可以优先选择柱塞泵，其可以提高足够的高压，为了实现主机壳体沿轴线1所在平面下的周长大于主机壳体沿垂直于轴线1所在平面下的周长，电机5和泵4可以沿轴线1方向排布，当第一壳体2和第二壳体3沿轴线1方向排布时，电机5设置在靠近敞口22的下方，电机5大体位于第一壳体2内，泵4大体位于第二壳体3内。
为了进一步提高第一壳体2和第二壳体3接合处的密封效果，如图3和图5所示，第一壳体2朝向第二壳体3的端部与第二壳体3朝向第一壳体2的端部之间可以设置有主机壳体密封件6，即第一壳体2的上端与第二壳体3的下端的接合处可以设置有主机壳体密封件6。在一种可行的实施方式中，第一壳体2朝向第二壳体3的端面具有凹槽21，主机壳体密封件6设置在凹槽21中，第二壳体3朝向第一壳体2的端面具有嵌入凹槽21的凸起部31。在另一种实施方式中，第二壳体3朝向第一壳体2的端面具有凹槽21，主机壳体密封件6设置在凹槽21中，第一壳体2朝向第二壳体3的端面具有嵌入凹槽21的凸起部31。在上述两种实施方式中，凹槽21和凸起部31均呈环状，以实现第一壳体2和第二壳体3周向一圈的全部密封。主机壳体密封件6可以采用具有一定 弹性的密封圈。当凸起部31嵌入凹槽21中时，凸起部31能够压紧主机壳体密封件6，再使主机壳体密封件6压紧凹槽21，通过上述方式有效提高第一壳体2和第二壳体3接合处的密封性。
在其它可行的实施方式中，第一壳体2和第二壳体3之间还可以采用超声波焊接或灌胶密封的方式进行密封，即将第一壳体2朝向第二壳体3的端部与第二壳体3朝向第一壳体2的端部之间采用超声波焊接或灌胶的方式连接在一起以使两者之间保持密封。因此，主机壳体密封件可以是密封圈或灌胶体或主机壳体材料等。
如图4所示，为了能够使得凸起部31压紧主机壳体密封件6或凹槽21，因此需要对第一壳体2和第二壳体3实现紧固，在一种可行的实施方式中，第一壳体2和第二壳体3之间通过紧固件15实现紧固连接。具体而言，紧固件15可以是螺钉、螺栓等等。第二壳体3的侧壁内具有螺纹孔，第一壳体2的侧壁上具有贯穿孔，再将紧固件15穿入贯穿孔拧入螺纹孔，通过拧紧紧固件15以实现第一壳体2和第二壳体3的紧固，并使得凸起部31压紧主机壳体密封件6或凹槽21。为了保证密封效果，螺纹孔和贯穿孔可以为多个，其可以呈圆周分布或沿着轴线方向分布，具体取决于第一壳体2和第二壳体3之间的上下结构或左右结构的拼接方式。另外，螺纹孔和贯穿孔所在的位置位于凸起部31与凹槽21所在的位置的外侧，如此，避免水通过螺纹孔和贯穿孔处进入主机壳体内部。
如图3和图4所示，清洗机的主机可以包括：支撑座7，支撑座7与主机壳体的下端之间可拆卸连接，支撑座7与主机壳体之间在径向方向和/或轴向方向上可以通过支撑座密封件进行密封，支撑座密封件可以为密封圈或灌胶体等。支撑座7用于对主机壳体进行支撑，使其能够竖直放置。
如图3和图4所示，支撑座7与主机壳体之间设置有滤网105，滤网105靠近敞口22设置，支撑座7上具有进水口71，自进水口71流入的水经过滤网。具体而言，主机壳体下端的外侧壁具有外螺纹，支撑座7上端的内侧壁具有内 螺纹，主机壳体和支撑座7通过螺纹连接实现可拆卸连接。可选的，支撑座密封件包括套设在主机壳体下端的外侧并径向抵压在支撑座与主机壳体下端之间的径向密封圈1，以实现径向方向的密封。进一步的，为了保证良好的密封性，支撑座7与主机壳体下端之间可以配置双向(轴向+径向)密封。具体的，支撑座密封件包括轴向抵压在主机壳体下端面与支撑座上端面之间的轴向密封圈18，以实现轴向方向的密封。当然的，17和支撑座与主机壳体下端的配件缝隙也可以是通过灌胶体密封。
主机壳体的下端具有敞口22，清洗机的主机可以包括：安装在主机壳体内的泵4，泵4的进口41通过敞口22与进水口71相连通。支撑座7的进水口71可以位于中部，水通过进水口71流入支撑座7，然后经过滤网、敞口22再流入泵4的进口41。滤网可以设置在主机壳体的下端的敞口22处，也可以设置在支撑座7的进水口71等。由于第一壳体2和支撑座7可拆卸连接，因此可以方便的将支撑座7拆卸下来，从而对滤网进行清洗。同时，通过第四密封件17和第五密封件18对主机壳体与支撑座7之间进行密封，因此，水必须经过滤网，无法从主机壳体与支撑座7之间进入至泵4的进口41。当然，在其它实施方式中，图9为本发明实施例中清洗机在一种可行的实施方式下的结构图，如图9所示，支撑座7与主机壳体之间可以一体成型，过滤网可以设置在进水口71处或设置在与进水口71相连接的过滤装置中。所述主机壳体可以具有直接置于外界水源中的工作模式，此时，所述敞口为流体介质的直接吸入口。当然，清洗机的主机壳体也可以不直接置于外界水源中，通过在敞口处连接软管，将软管的另一端置于外界水源中。
如图3和图4所示，在一种可行的实施方式中，电机5靠近敞口22设置，外壳包括周向上包绕至少部分电机5外围的电机外壳14。进水通道包括连通泵4的进口41的连接管单元13、流通在电机外壳14与主机壳体之间第二流道25、以及供连接管单元13插入并与第二流道25连通的第一流道24。进水密封结构16圈设在电机外壳14和第一流道24的外壁之间。在流体流动的方向上，第一 流道24位于第二流道25和连接管单元13之间。
具体的，主机壳体具有隔离部23，主机壳体和隔离部23之间形成有第一流道24，电机外壳14与至少部分主机壳体的内侧壁、隔离部23之间形成至少一部分第三装配间隙，第三装配间隙通过进水密封机构16进行密封。进水密封机构16可以为环状密封圈或灌胶体等等。例如，主机壳体为上下结构拼接时，第一壳体2位于第二壳体3的下方。电机外壳14与至少部分第一壳体2的内侧壁、隔离部23相紧贴，且电机外壳14与至少部分第一壳体2的内侧壁、隔离部23之间设置有进水密封结构16。
如图3所示，电机外壳14的下端与主机壳体具体为第一壳体2之间形成有第二流道25，第二流道25与第一流道24相连通，第二流道25与敞口22相连通。电机外壳14与至少部分主机壳体(具体为第一壳体2)的内侧壁、隔离部23之间的密封处高于第二流道25。当水自敞口22流入主机壳体后，进入第二流道25，然后进入至第一流道24。由于电机外壳14与至少部分第一壳体2的内侧壁、隔离部23之间密封，水无法进入流入至安装腔102内其它地方，只能流入至第一流道24，如此有效避免水对电机5、泵4等器件造成影响，防止短路。
如图3所示，连接管单元13的一端插入至第一流道24中，连接管单元13的另一端与泵4的进口41相连通。进入第一流道24的水通过连接管单元13在主机壳体内流入至泵4的进口41，无法流至主机壳体内的其它地方。
在一种可行的实施方式中，连接管单元13可以沿轴线1方向延伸，连接管单元13靠近主机壳体的内侧壁。通过上述方式避免连接管单元13对电机5和泵4的位置造成影响，其能让电机5和泵4基本位于主机壳体的轴线1上。优选地，连接管单元13可以包括第一连接管131、第二连接管132以及弯管43，第一连接管131插入至第一流道24中，泵4的进口41连接有弯管43，第二连接管132的上端与弯管43相插接，第一连接管131和第二连接管132通过插接方式连接。
为了进一步保证上述插接处的密封性，清洗机还包括径向挤压在第一流道24与第一连接管131之间的第三密封件133，以阻断第一流道与第一连接管之间的插接间隙与安装腔102之间的通路；径向挤压在弯管43与泵4的进口41之间的第四密封件44，以阻断泵4的进口41与弯管43之间的插接间隙与安装腔102之间的通路；第一连接管131和第二连接管132的插接处形成过盈配合，以阻断第一连接管131和第二连接管132之间插接间隙与安装腔102之间的通路；第二连接管132与弯管43之间形成过盈配合，以阻断第二连接管132弯管43之间的插接间隙与安装腔102之间的通路。
具体的，在一种实施方式中，第三密封件133和第四密封件44可以设置环状密封圈。第一连接管131的外壁与第二连接管132的内壁相挤压配合，或者第一连接管131的内壁与第二连接管132的外壁相挤压配合。清洗机进一步包括包裹在第一连接管131与第二连接管132挤压区域外围的第一紧固件，以保证第一连接管131和第二连接管132过盈配合。同样的，第二连接管132的内壁与弯管43的外壁相挤压配合，或者第二连接管132的外壁与弯管43的内壁相挤压配合。清洗机进一步包括包裹在第二连接管132与弯管43挤压区域外围的第二紧固件，以保证第二连接管与弯管43过盈配合。
由于第一壳体2和第二壳体3之间紧固连接在一起，因此，第一连接管131、第二连接管132、第一流道24和弯管43之间相互都是抵住的，其插接处不会出现松动，因此可以有效减小因松动而出现的泄露。如图3所示，第一连接管131和第二连接管132的插接处大体位于第一壳体2和第二壳体3的接合处，如此，当安装清洗机的主机时，第一连接管131先插入至第一流道24中，第一连接管131与插入至第一流道24处的主机壳体之间具有第三密封件133，以阻断第一流道24与第一连接管131之间的插接间隙与所述安装腔之间的通路。第二连接管132插入至泵4的进口41连接的弯管43中，再将第一壳体2和第二壳体3接合时，可以方便的将第一连接管131与第二连接管132直接相插接，从而可以在保证连接密封性的前提下高效完成主机壳体内水路的连接。
如图3所示，第二壳体3的横截面由第一壳体2方向向开孔32方向呈逐渐缩小趋势。第一壳体2的横截面由第二壳体3方向向敞口22方向呈逐渐缩小趋势。通过上述结构可以方便的将电机5、泵4等部件从第一壳体2呈开口状的一端、第二壳体3呈开口状的一端安装进入主机壳体内部，同时可以保证主机壳体内的空间被充分利用，使得整个主机壳体的体积优化缩小，便于清洗机主机的携带。
如图3所示，在一种可行的实施方式中，电机5与泵4之间通过减速机构相传动连接，所述电机5、所述减速机构以及所述泵4在电机轴的延伸方向上依次排布。具体而言电机5与泵4之间可以通过行星齿轮机构12相传动连接。通过行星齿轮机构12可以实现将电机5的转速降低后传递给泵4，同时，可以使得电机5的轴与泵4的轴位于同一直线上，基本位于轴线1上或与轴线1相平行，这样可以最大程度的降低主机壳体的径向尺寸，不会出现电机5在主机壳体下端偏向于左边，泵4在主机壳体上端偏向于右边，或者两者进行对调。通过上述方式使得主机壳体沿垂直于轴线1所在平面下的周长变得最小，需要进行密封的周长最短，能够进一步降低第一壳体2和第二壳体3接合处出现漏水的可能性。
如图3和图4所示，在一种可行的实施方式中，管线8连接在手持喷枪和主机之间，用于将泵4加压后的流体引导到喷枪进液口202。管线8的一端具有用于将管线8与泵4的出口42相连接的管线接头。
在一种可行的实施方式中，管线与主机壳体之间形成管线装配间隙。主机100包括管线密封机构，其阻断管线8与主机壳体的管线装配间隙与安装腔102之间的通路。主机壳体的上端可以具有开孔32。管线8穿设在开孔32中。管线密封机构包括设置在管线8与主机壳体之间的密封圈、灌胶体、防水黏合剂中的一种或者多种组合体。通过上述方式实现管线8与主机壳体的管线装配间隙到安装腔之间通路的密封。
在另一种可行的实施方式中，管线为水电一体管时，具体的，水电一体管 包括流体连通泵4的出口42与喷枪进液口202的水路通道81和将电机与电池包201电性连接的导电线82。水电一体管的一端部与手持喷枪一体插接，水电一体管的另一端部自开关延伸入安装腔102并与泵4的出口42相连接。主机壳体的上端可以具有开孔32，管线8穿设在开孔32中。如图3所示，管线密封机构包括：套设在管线8外侧的保护管套9，套设在保护管套9外侧的密封盖10。保护管套9至少部分设置在密封盖的上端部与管线8之间；密封盖10配置为向内抵压保护管套9，以形成密封盖10与保护管套9相接触的区域的至少部分为无间隙配合，且密封盖10能够施予压紧力使保护管套9与管线8相接触的区域的至少部分为无间隙配合。密封盖10与主机壳体的上端具体为第二壳体3的上端相连接以使保护管套9与第二壳体3相压紧。在其它实施方式中，主机壳体与密封盖10可以为一体成型。
在一种可行的实施方式中，电池包201可以以可拆卸的方式安装在手持喷枪200上。当管线8为水电一体管时，管线8的水路不仅连接泵4的出口与喷枪进液口，同时管线8的电路还连接电池包201和电机5。电池包201安装在手持喷枪200上，可以方便电池包201的及时更换，尤其在主机100置于水中时，当使用过程中没电时，避免了需要将主机100从水中取出再更换电池包201，从而降低了拆装电池包201时可能出现的水进入主机壳体的可能性，用户可直接在手持喷枪200上更快方便的更换电池包201，进而继续使用清洗机。另外，电池包201安装在手持喷枪200上，电机5、泵4安装在主机100上，如此使得电池包201和电机5、泵4分开布置，可以均衡主机100与手持喷枪200的重量。电机5、泵4独立安装在主机100上，可以使得手持喷枪200的体积更小，更加轻便化。而且，电机5、泵4放置在主机里，没有安装在手持喷枪200上，可以不受限于手持喷枪200对于轻量化的更严苛的要求，也可以实现更高压力的输出，兼顾手持轻量化和高性能的需求。当然，电池包201也可以不安装在手持喷枪200上，在本申请中并不对其做任何限制。
在一种可行的实施方式中，电池包201标称的输出电压小于等于42.4V， 其可以驱动电机使得泵输出的水压大于2.5Mpa。该清洗机可以利用普通输出电压的电池包便可以输出水压大于2.5Mpa的水流，满足高压冲洗需求。
如图3所示，在一种可行的实施方式中，保护管套9具有较长的长度，如此可以增加保护管套9与管线8相紧贴的距离，从而提高保护管套9与管线8之间的密封性，降低水从保护管套9与管线8之间进入主机壳体的内部。同时，保护管套9可以呈柔性，如此在水电一体管弯折时可以有效保护水电一体管中的电线防止其发生断裂。
如图3所示，在一种可行的实施方式中，开孔32处具有向其中心延伸的内延伸部33，保护管套9具有沿径向方向向外延伸的外延伸部91，保护管套9的下端抵住内延伸部33，密封盖10的内侧壁具有一限位部101，限位部101抵住外延伸部91，以使外延伸部91压紧内延伸部33，从而阻断主机壳体与密封盖10之间的螺纹装配间隙与所述安装腔之间的通路。
为了提高密封盖10、第二壳体3的内延伸部33、保护管套9的外延伸部91之间贴紧程度，以进一步增加密封性，如图3所示，第二壳体3上端的外侧壁上具有外螺纹，密封盖10下端的内侧壁上具有内螺纹，第二壳体3与密封盖10通过螺纹相连接。通过螺纹可以调节密封盖10与第二壳体3之间的距离，从而控制密封盖10压紧保护管套9的外延伸部91的程度，保护管套9的外延伸部91压紧第二壳体3的内延伸部33的程度。
通过上述多种方式可以使得保护管套9与管线8之间无间隙；密封盖10与保护管套9的外延伸部91之间无间隙；保护管套9的外延伸部91与主机壳体的内延伸部33之间无间隙，进而避免水通过管线装配间隙进入至主机壳体内部的安装腔。
在一种可行的实施方式中，如图3所示，管线8为水电一体管时，水路流道81形成在水电一体管的中部，位于主机壳体内的水电一体管的端部的水路流道81与泵4的出口42相连通。水电一体管的端部具有水路连接件，水路连接件能够插入泵4的出口42实现密封连接，以使水电一体管的中部的水路流道 81与泵4的出口42相连接。管线接头包括上述水路连接件。导电线82设置在水电一体管的侧壁，水路流道81与所述导电线82的相应端部与所述手持喷枪200一体插接。位于主机壳体内的水电一体管的一端部的导电线82与电机5相电性连接，水电一体管的另一端部的导电线82与所述电池包201相电性连接。通过泵4将从第一壳体2下端敞口22吸入的水吸入水进行加压，加压后的水从泵4的出口42流出，经过水电一体管的水路流道81流出主机壳体，以供喷枪清洗使用。第二壳体3与密封盖10之间设置有第一密封件11，阻断主机壳体与密封盖10之间的螺纹装配间隙与安装腔102之间的通路。第一密封件11可以是具有一定弹性的密封圈。管线密封机构包括第一密封件11。通过上述方式提高第二壳体3与密封盖10之间的密封性，减少水从第二壳体3与密封盖10之间的螺纹进入的可能。
在一种可行的实施方式中，图6为本发明实施例中管线与主机壳体处在一种可行的实施方式下的结构图，如图6所示，当管线8为水管或水电一体管时，管线密封机构可以包括：套设在管线8外侧的保护管套9，；套设在保护管套9和主机壳体上的密封盖10。保护管套9的上端具有沿径向方向向外延伸的外延伸部91及在轴向方向上沿着管线延伸方向延伸一端距离的内延伸部92，密封盖10与主机壳体的上端具体为第二壳体3的上端相螺纹连接，以使密封盖10与第二壳体3能够压紧保护管套9的外延伸部91。保护管套9的外延伸部91挤压在密封盖10的内壁面与主机壳体的上端面之间，以形成保护管套9与密封盖10以及主机壳体在上下空间内为无间隙配合。进一步的，保护管套9的内延伸部92挤压在管线8主机壳体的内侧面之间，以形成保护管套9与密封盖10以及主机壳体在左右空间内为无间隙配合；通过上述方式管线密封机构将管线8与主机壳体之间的管线装配间隙到安装腔之间的通路进行密封。
在一种可行的实施方式中，图7为本发明实施例中管线与主机壳体处在一种可行的实施方式下的结构图，如图7所示，当管线8为水管或水电一体管时，管线密封机构可以包括：套设在管线8外侧的保护管套9，保护管套9位于管 线8的外侧壁和主机壳体的内壁之间，其用于将管线8的外侧壁和主机壳体的内壁之间进行密封封堵；套设在主机壳体上端处的密封盖10，密封盖10与主机壳体之间螺纹连接，管线8穿设过密封盖10。通过上述方式(保护管套将管线8的外侧壁和主机壳体的内壁之间进行密封封堵)将管线8与主机壳体之间的管线装配间隙到安装腔之间的通路进行密封。
在一种可行的实施方式中，图8为本发明实施例中管线与主机壳体处在一种可行的实施方式下的结构图，如图8所示，出水通路包括泵4的出口部，管线的端部通过水路连接件插入泵4的出口部形成的出口42中。主机壳体上具有开孔32，出口部自安装腔102向开孔32方向延伸，以形成出口部靠近主机壳体的最上端或者与主机壳体的最上端相平齐或者超出主机壳体的最上端。出口部与主机壳体之间形成第二装配间隙，管线密封机构包括位于出口部与主机壳体之间的出口部密封件45。此时，管线密封机构可以为密封圈或灌胶体等。
优选地，管线密封机构可以包括：套设在管线8上的密封盖10，密封盖10的内壁侧紧贴管线8的外壁，密封盖10的外侧壁与主机壳体的内壁之间通过螺纹连接，密封盖10具有周向向外的边缘；设置在边缘与主机壳体之间的第一密封件11，当密封盖10与主机壳体之间拧紧时，密封盖10就会压紧第一密封件11，从而达到较好的密封作用。通过上述方式管线密封机构将管线8与主机壳体之间的管线装配间隙到安装腔之间的通路进行密封。
在一种可行的实施方式中，如图9所示，当管线8为水管或水电一体管时，管线密封机构可以包括：套设在管线8上的保护管套9，保护管套9的下端位于管线的外侧壁和主机壳体的内壁之间，保护管套9外壁与主机壳体的内壁相螺纹连接，保护管套9具有沿径向方向向外延伸的外延伸部91；套设在管线8上的密封盖10，密封盖10的内壁与保护管套9上端的外壁相螺纹连接；设置在外延伸部91与主机壳体之间的第一密封件11，当保护管套9与主机壳体之间拧紧时，保护管套9就会压紧第一密封件11，从而达到较好的密封作用；设置在保护管套9的上端与管线8之间的第六密封件19，当保护管套9与密封盖 10之间拧紧时，密封盖10就会压紧第六密封件19，从而使得保护管套9与管线8之间达到较好的密封作用。通过上述方式管线密封机构将管线8与主机壳体之间的管线装配间隙到安装腔之间的通路进行密封。
