如图10~11、图13~14所示,揭示一种高压清洗机组件100,其包括高压清洗机1及与高压清洗机1电性连接的能量单元。所述能量单元为直流电源。具体的,该直流电源可以为电池包2。

高压清洗机1还包括连接电机111的传动机构112、受传动机构112带动的泵113。该传动机构112用于将电机111的旋转运动转换成泵113的往复运动。电机111、传动机构112以及泵113构成高压清洗机1的功能部件。具体的,传动机构112为齿轮减速机构。

继续参照图1至图8,包盖21和包底22分别具有容纳腔,包盖21和包底22相互对合构成电池包壳体。电池包壳体设有能够和所述对接面140对接配合配合面211、并限定有收容电芯组23和电池接线排25的安装腔20。在本实施方式中,配合面211形成于包盖21上。更具体的,包盖21包括上表面212、自上表面212向上凸伸出的凸台213。该凸台213包括顶表面2131、连接上表面212和顶表面2131之间的一对侧表面2132以及一前端面2133。其中配合面211由包盖21的一个面或多个面组合形成。在本实施方式中,电池接线排25收纳在凸台213和电芯组23围设的腔室内。
电芯组23包括以行或行列堆叠方式设置于安装腔20内的若干电芯231。各电芯231均包括电芯体部2311、位于电芯体部2311一侧的第一电极端2312及位于电芯体部2311另一侧的第二电极端2313。第一电极端2312与第二电极端2313相对设置且电极的极性相反。为保证各电芯231之间能够形成电性连接,位于电芯体部2311一侧的相邻的第一电极端2312的极性相反。电池接线排25包括与壳体端子142电连接的若干电池包端子251。在其中一种可行实施方式中,如图4所示,电池接线排25还包括承载该等电池包端子251的端子座252,电池接线排25通过导电件253和电池包控制板24电性连接。具体的,导电件253可以是导电极片或者导线;在另一种可行方式中,如图2所示,电池包端子251直接支撑在电池包控制板24上,并与电池包控制板24电性连接,即电池包控制板24可作为端子座。
如图10和图12所示,电池包2还包括安装在电池包壳体上的连接脱扣装置26。连接脱扣装置26能够相对于电池包壳体运动,以实现电池包2与手持式高压清洗机1相连接或脱离。具体的,连接脱扣 装置26包括操作部261和卡接部262。操作部261具体为按钮。按钮能够带动卡接部262相对于电池包壳体上下活动,以实现电池包2可操作地从壳体10上退出。进一步的,连接脱扣装置26的底面和包盖21的外表面之间设置有弹性装置263。优选的,该弹性装置263为弹簧。包盖21的外表面设有安装槽210,上述弹簧至少部分限位在安装槽210内。在需要将电池包2从手持式高压清洗机1上拆卸下来时,按压按钮,按钮带动卡接部262向下运动与手持式高压清洗机1脱离。此时,弹簧因为受到按钮的压力给按钮一个向上的复位力,用于使连接脱扣装置26被按压后又恢复至原来的高度。
进一步的,在本实施方式中手持式高压清洗机1与电池包2插接配合形成有供壳体端子142与电池包端子251进行电性连接的插接口27。该插接口27可选择的配置在手持式高压清洗机1或电池包2上。根据插接口27设置的位置不同,本发明提供两种形态结构的电池包2。
具体的,如图1~图8所示,当所述插接口27配置在电池包2上,电池包2具有第一种形态结构。即壳体端子142配置为向外凸伸的接片型端子,电池包2的配合面211上形成有供壳体端子142插入以与电池包端子251电性连接的所述插接口27。
当上述插接口27配置在手持式高压清洗机1上,电池包具有第二种形态结构(未图示)。此时,电池包端子配置为向外凸伸的接片型端子(未图示)。电池包端子通过所述插接口插入壳体10内以与壳体端子142进行电性连接。
由于本公开实施例中,电池包2是以第一种结构呈现,因此如下仅对第一种结构进行详细说明。
手持式高压清洗机1可以根据清洗场景和清洗对象差异定位有不同的工作水压和工作水流量范围。具体的,在本公开实施例中,手持式高压清洗机1向外输出的工作水压可以在0.2Mpa~10Mpa范围内选取定位为具体值或者范围值,向外输出的工作水流量可以在1.5L/Min~8L/Min范围内选取定位为具体值或者范围值。如手持式高压清洗机1的工作水压可以定位为0.3~2.49Mpa,工作水流量可以定位为1.5L/Min~3.4L/Min;或者手持式高压清洗机1的工作水压定位为0.3Mpa~5Mpa,工作水流量可以定位为1.5L/Min~6L/Min。
此外,在本实施方式中,电池包2的数量设有一个或多个,在其中一个实施方式中,电池包2的数量为一个,电池包2的电压为18V~60V,即电池包2的电压可以为18V、20V、28V、36V、38V、40V、42V、56V、60V。电池包2的容量可以为1.5Ah、2Ah、2.5Ah、3Ah、4Ah。当然,在其它可实施方式中,电池包2的数量也可为两个。
需要注意的是,电池包2供电的手持式高压清洗机1势必能够满足用户对于便携性的需求。但相关的测试标准中,对于直流式手持式高压清洗机1具有相应的防水要求。只有满足相应的防水要求,直流手持式高压清洗机1才能保证用户使用机器的安全性。这里的防水要求应该理解为针对手持式高压清洗机1具有的相应工作水压和电池包2具有的相应电压下,将配接有电池包2的手持式高压清洗机1置于相应的极端环境下,并能保证机器能够满足防水标准。需要继续强调的是,相对于其它电动工具,直流手持式高压清洗机1限制于用户握持机器方式的多样性(根据使用场景或者清洁工况的不同,用户可以径向转动机身,选择合适的角度握持机器),其对于防水要求更为严格。因此,这里的极端环境应该理解为,配接有电池包2的手持式高压清洗机1需进行多向测试。即,竖向握持机器或者横向握持机器或者将机器翻转180度形成的倒置机器等均能满足相应工作水压和电池包2电压下对应的防水要求。
目前,市面上有很多单一的电池包防水方案,然而,这些方案中要么仅能做到电池包的局部区域可 以杜绝水流进入至电池包的安装腔,要么仅能做到单一测试方向上(机器竖向放置),局部区域可以杜绝水流进入电池包的安装腔。而这些对于防水要求较高的手持式高压清洗机组件(手持式高压清洗机和电池包配接形成手持式高压清洗机组件)根本无济于事,不能完全解决防水问题。
在本公开实施例中,首先,手持式高压清洗机1和电池包2插接配合,通常情况下,配合处存在配合余量。即电池包2与手持式高压清洗机1相互接触的面不可能是完全紧密的贴合,且电池接线排25和电池包安装腔20的内壁之间会存在装配间隙。外界水流能够顺着手持式高压清洗机1和电池包2之间的配合余量流进入电池包的插接口27内,并自电池接线排25和电池包安装腔20的内壁之间的间隙流入至电芯组23。进而,电芯组23的两电极端(第一、第二电极端2312、2313)和电芯体部2311之间均有可能接触水流。如此,易于带来电池包2内电路短路,造成漏电、触电、甚至电芯爆炸等安全风险。为此,本公开实施例提供了以下几种电池包防水实施方式,如下进行详细介绍:
具体的,电池包2包括包覆各电芯231至少部分结构的防水透气结构3。
作为本公开实施例中电池包2防水的第一种实施方式,如图1所示,该防水透气结构3包括包裹各电芯231第一电极端2312的第一防水体31及包裹各电芯231第二电极端2313的第二防水体32。换句话说,即各电芯231未完全被防水透气结构3包裹,仅各电芯231的两个电极端包覆有防水透气结构3。这样的话,将配接有电池包2的手持式高压清洗机1置于相应的测试环境下,能保证各电芯231的两电极端没有水。进一步的,上述电池包控制板24和/或电池接线排25可设置在第一防水体31和第二防水体32之间。一方面,降低防水材料的成本及电池包2的重量;另一方面,可以预留出安装区域供电池包控制板24和/或电池接线排25安装。其中,在一种可实施方式中,,第一防水体31和第二防水体32可以为通过灌胶形式形成的灌胶体。当然,第一防水体31和第二防水体32也可以设计为防水胶布。在另一种可实施方式中,第一防水体31和第二防水体32均为防水材料制成的密封盒体(未图示),密封盒体和电芯组23的搭接处可通过附着黏合体(具体可以为防水黏合剂)密封。
更进一步的,在本实施方式中,包底22还设有排水孔220,水流能够沿着电芯组23和包底22之间的空间到达排水孔220,并通过排水孔将渗入电池包安装腔20内的水流向外排出。其中,排水孔220的数量可以为一个或若干个,例如可以配置有六个排水孔或者八个排水孔等等。对于排水孔为若干个的情况,相邻的排水孔相对于彼此偏移。优选的,电池包2还包括设置在电芯组23和排水孔220之间的排水路径,用于引导水流沿着一定的路径向外快速向外排出。优选的,排水孔220设置在包底22的最低处。如此设计,可以确保相邻的电芯231之间不会有积水。
在本实施方式中,仅改变电池包2的电芯组23的结构设计,并结合包底22设有的排水孔220,即可实现电池包2配接于手持式高压清洗机1形成的整机能够满足一定条件下的测试标准。现有的电池包2平台改动小,成本低,电池包2的体积增加量也小。
作为本公开实施例中电池包2防水的第二种实施方式,其与第一种实施方式的差异主要在于,第一种实施方式,电芯组23被部分包裹,而在本实施方式中,电芯组23整体被密封包裹。具体的,该防水透气结构3还包括包覆各电芯体部2311外围的第三防水体(未图示)。如图2所示,第一防水体31、第二防水体32、第三防水体一体形成为独立的整体结构,该独立的整体结构完全包覆于所述电芯组23的外围,以阻止外界水流流入至电芯的两电极端和/或附接在各电芯231之间。
该防水透气结构3为通过灌胶形式形成的灌胶体34,该灌胶体34完全包裹于电芯组23。如前所述, 电池包2还包括电性连接在电芯组23与电池包控制板24之间的导电件253。为避免导电件253与灌胶体34之间形成空隙,因此,导电件253和灌胶体34的连接处还涂敷有防水黏合剂,以避免水流透过该等空隙流入至电芯组23上。当然,该防水透气结构3也可设计为防水胶布。防水胶布能够直接缠绕于电芯组整体的外围。
作为本公开实施例中电池包2防水的第三种实施方式,其与第一种实施方式的差异主要在于,第一种实施方式,电芯组23被部分包裹,而在本实施方式中,电芯组23整体被密封包裹。具体的,如图3所示,该防水透气结构3为收容在安装腔20内的密封盒体35。该密封盒体35为防水材料制成。密封盒体35包括相互接合的第一密封盒体351和第二密封盒体352。第一密封盒体351和第二密封盒体352接合后形成一收容空间。电芯组23全部收容在该收容空间内。其中,第一密封盒体351和第二密封盒体352可通过螺钉紧固或者卡扣的方式紧固接合。为了避免第一密封盒体351和第二密封盒体352机械接合后,两个密封盒体之间存在合缝。在本实施方式中,电池包2还包括设置在第一密封盒体351和第二密封盒体352之间的接合密封件353。当第一密封盒体装配至第二密封盒体,接合密封件353阻断外部水流通过接合缝隙流入至收容空间内。具体的,该接合密封件353可以为密封圈,第一密封盒体351和第二密封盒体352相接触,并对密封圈形成挤压,以密封装配间隙。当然,接合密封件353也可以为防水黏合剂。
同样的,电池包2还包括电性连接在电芯组23和电池包控制板24之间的导电件253。为避免导电件253与密封盒体之间形成有影响密封性的空隙。因此,导电件253和密封盒体的连接处还涂敷有防水黏合剂354,以避免水流透过该等空隙流入至电芯组23上。
作为本公开实施例中电池包防水的第四种实施方式,首先,由于电池接线排25和电池包2的安装腔20之间具有装配间隙,因此,插接口27和安装腔20内部相连通。从插接口27进入的水流可以通过该装配间隙流入至安装腔20内。如图4所示,本实施方式中,电池包2配置有阻断从所述装配间隙到电芯组23之间的通路的密封构件4。且密封构件4设置在电池包2的安装腔20内。
其中,在一种可行方式中,密封构件(未图示)被压紧在插接口270和端子座251之间。具体的,密封构件4处于自由状态下的厚度大于端子座251到插接口27之间的间隙,以填充端子座251和电池包内壁之间的间隙,阻止从插接口27进入的水流进一步流入到安装腔20内。
在另一种可行方式中,当电池接线排25配置为由电池包壳体支撑,如图4所示,密封构件4为压紧在所述电池接线排25和电池包壳体之间的环形防水结构41。使得电池接线排25与电池包内壁之间的空隙被填充密封。当电池接线排25配置为支撑在电芯组23上(如图2中电池接线排25的位置),在包盖21和包底22的接合方向上,密封构件4被挤压在电池接线排25和电芯组23之间,在自第一电极端2312到第二电极端2313的方向上,密封构件4被挤压在电池包壳体和电池接线排25之间。具体的,密封构件4连接在电池包2的端子座252上。端子座252的外周边上形成有环形状的凹槽(未图示)。密封构件4装配在该凹槽中。进一步的,电池包2还包括将密封构件4和凹槽黏合成一体的黏合剂。需要说明的是,密封构件4即可以理解为封堵在电池接线排25和安装腔20之间的隔墙,所以即使水流能沿着电池包2上的插接口27流入,也无法进入安装腔20内。
在又一种可行方式中,如图5所示,端子座252构造为一防水箱体,电池包端子251与防水箱体252一体成型。该防水箱体252面向插接口27的方向设有供壳体端子142穿插的开口。其中开口可以设计为 独立整体式。也可以设计为复数个相对彼此偏移,且复数个开口和所述电池包端子251一一对应。密封构件4密封在电池包2的内壁和防水箱体252之间,以封堵所述防水箱体252和电池包内壁之间的装配间隙。进一步的,防水箱体252在包盖21和包底22接合方向上的最大横截面积不小于插接口27在所述接合方向上的横截面积。通过改变传统的电池包接线排25结构,利用端子座252结构的变形,一方面,保证了电池包端子251无障碍的与壳体端子142电性插接;另一方面,使得水流仅能流入至防水箱体内,而无法接触电芯组23。
进一步的,还提供一种可行方式,密封构件(未图示)附着在插接口27上,且附着在插接口上的密封构件设置在电池包2的内壁上,与所述电池包2的配合面211背靠背设置。密封构件设有供壳体端子142穿插的贯通孔,为了保证密封性,贯通孔和壳体端子干涉配合,且贯通孔配备为不妨碍密封构件隔离插接口27和电芯组23的构造供壳体端子142穿插。
其中第四种实施方式中所列举的上述诸多可行方式中,密封构件4为块状软性密封垫、灌胶形式形成的灌胶体、防水黏合剂、焊接形成的熔合体中的一种或者多种组合体。
此外,如图6所示,在该可行方式中,密封构件4为设置在电池接线排25和电芯组23之间的分隔板42,电芯组23位于分隔板42和电池包内壁围设的密封空间内。分隔板42的四周缘和电池包的内壁相抵。密封构件4还包括黏附在分隔板42的四周缘和电池包内壁之间的防水黏合剂或者防水垫圈43。具体的,安装腔20内设有前后(即电池包的插接方向)平行的两个支架,分隔板42位于两个平行架202之间。在前后方向上,防水黏合剂黏附在分隔板42和两个平行架之间。当然,安装腔20内可以在左右方向(即第一电极端2312至第二电极端2313的方向上)上也设有平行的两个支架,即分隔板支撑在上述四个支架上,装配稳定性更高。
其次,本公开实施例提供的电池包2的包盖21、包底22为分体结构。包盖21与包底22通过螺钉(未图示)紧固连接。而通过螺钉紧固连接,包盖21与包底22的连接处势必存在装配间隙。外界水流能够通过该装配间隙流入至电池包2的安装腔20内,导致各电芯231的两电极端上有水和/或电芯组23之间有积水,从而引起电池包2内电路短路,造成漏电、触电、甚至电芯爆炸等安全风险。因此,在本实施方式中,如图4所示,电池包2还配置有阻断从包盖21和包底22之间的装配间隙到电芯组23之间的通路的电池包壳体密封件28。电池包壳体密封件28设置在包盖21和包底22的连接处,当包盖21和包底22对合完成,电池包壳体密封件28阻断外部水流流入至安装腔20内。需要说明的是,这里的连接处不仅仅是螺钉紧固的区域或者卡扣结构卡合的区域,而是包盖21的整个外周边缘和包底22的整个外周边缘相接触的区域。在一种可行实施方式中,电池包壳体密封件28为软性密封垫。当包底22和包盖21相接触,对软性密封垫产生挤压,以对包盖21和包底22之间的装配间隙密封。当然,在其他实施方式中包盖21和包底22可以通过焊接的方式进行密封,例如超声波焊接或者激光焊接。
优选的,如图4、图8和图10所示,电池包2还包括表征电池包工作特性的显示装置29及收容显示装置的显示装置收容腔201。显示装置收容腔201位于安装腔20内。显示装置29包括显示装置控制板291、与显示装置控制板291电性连接的电量显示灯292及电量显示按钮293,电量显示按钮293可操作地被触发以点亮电量显示灯292。在本实施方式中,显示装置收容腔201被上述电池包壳体密封件28限定为封闭的空间,以阻止外部水流通过显示装置收容腔201流入至电池包2内。
此外,发明人发现,现有的连接脱扣装置是装配在电池包壳体上,且连接脱扣装置至少部分位于安 装腔20内。连接脱扣装置能够相对于电池包壳体活动,以实现与壳体10的连接或脱离。换句话说,即连接脱扣装置与安装腔20之间具有供连接脱扣装置运动的活动间隙,外界水流很容易通过该活动间隙进入至电池包的安装腔内,导致电芯231的两电极端上有水和/或各电芯231之间有积水。
因此,在本实施方式中,连接脱扣装置26与安装腔20配置为彼此独立且不连通。具体的,连接脱扣装置26安装在电池包壳体上,且连接脱扣装置26隔离在电池包2的安装腔20之外。电池包壳体形成有供连接脱扣装置26运动的活动空间,该活动空间独立隔离在安装腔20之外,避免外部水流进入到活动空间时,进一步流入到安装腔20内。
在一种可行实施方式中,连接脱扣装置26可拆卸地安装在包盖21的外表面上。具体的,如图12所示,包盖21为一体成型,所述包盖21于其外表面下沉有至少部分包围连接脱扣装置26的锁扣腔214。锁扣腔214形成上述供连接脱扣装置26上下运动的活动空间,锁扣腔214和安装腔20彼此不连通,以防止外界水流进入到锁扣腔214时,进一步进入到安装腔20内。
在另一种可行实施方式中,电池包2还包括隔离件(未图示)。隔离件可拆卸地安装到电池包壳体上且隔离件向内凹陷有容纳连接脱扣装置26的锁扣腔。即通过隔离件将锁扣腔和安装腔进行隔离。在本实施方式中,电池包2还包括设置在隔离件和电池包壳体之间的隔离密封结构(未图示),以阻断隔离件和电池包壳体之间的装配间隙到安装腔内的通路。具体的,该隔离密封结构为挤压在隔离件和电池包壳体之间的软性密封垫。当然,在其他实施方式中,隔离件和电池包壳体之间也可以通过焊接的方式进行密封。
电池包防水的第四种实施方式中,在不对电芯组23结构作任何改变的情况下,仅通过封堵电池包2上的所有进水路径,即可实现电池包2配接于手持式高压清洗机1形成的整机能够满足一定条件下的测试标准。如此设计,在全方位保证电池包2防水可靠性的同时,结构简单,成本低,且电池包平台不需要作太大的改变,使得为手持式高压清洗机1供电的电池包2同样也可以为其他工具供电。
业界针对直流式高压清洗机1有不同的防水要求。该不同的防水要求是根据手持式高压清洗机1喷出工作水压及电池包的电压两方面一起考量。上述三种实施方式可确保喷出的工作水压小于2.5Mpa,电池包的电压小于42.4V的直流手持式高压清洗机组件满足安规标准中防水的要求。
并进一步能够保证当手持式高压清洗机1喷出的工作水压大于2.5Mpa,且与手持式高压清洗机1配接的电池包2的电压大于42.4V时,电池包2的防水能够满足安规标准中的要求。
需要继续强调的是,由于当手持式高压清洗机1喷出的工作水压大于2.5Mpa,且与手持式高压清洗机1配接的电池包2的电压大于42.4V时,业界针对直流手持式高压清洗机1防水要求更为严格,需要满足整机(手持式高压清洗机1和电池包2)上带电体表面不能有水,且需要满足一定的爬电距离。即可理解为不仅需要对电池包2上的带电体实施防水措施,还需要对收容在手持式高压清洗机1壳体10内的工具电器件实施防水,以保证手持式高压清洗机1满足防水标准的要求。为此,本公开实施例提供了以下几种防水实施方式,如下进行详细介绍:
首先,先介绍本公开实施例中是如何对收纳在壳体10内的工具电器件进行防水的。
作为本公开实施例中对壳体10内的工具电器件进行防水的第一种实施方式,如图9~11所示,壳体10的第一半壳101和第二半壳102均为实体结构,该第一半壳101和第二半壳102可通过螺钉或卡扣等常规的机械紧固方式连接并形成有收纳腔106。而通过螺钉或卡扣连接,第一半壳101和第二半壳102 的连接处势必存在接合间隙。外界水流能够通过该接合间隙流入壳体10的收纳腔106内,导致收容在壳体10内的工具电器件表面上有水。因此,在本实施方式中,如图13所示,壳体10还配置有阻断从第一半壳101和第二半壳102的接合间隙到收纳腔106之间的通路的主机壳体密封件5。主机壳体密封件5设置在第一半壳101和第二半壳102的连接处。当第一半壳101和第二半壳102装配完成,主机壳体密封件5阻断水流流入至壳体10的收纳腔106中。
在一种可行实施方式中,主机壳体密封件5为软性密封条。当然,在其他实施方式中,第一半壳101和第二半壳102也可以通过焊接的方式进行密封。即主机壳体密封件5也可以理解为防水黏合剂或者一种焊接密封方式,如超声波焊接。
进一步的,泵113包括泵体1131、收容在泵体1131内的柱塞(未示出)、设置在泵体1131上的水流进口(未示出)和水流出口(未示出)、以及中央腔室(未示出)。泵体1131上的水流进口和入水口1041连通设置。柱塞运动带动清洗液体通过入水口1041流至中央腔室内,并自泵体1131的水流出口向出水管110的方向流动。手持式高压清洗机1还包括与泵体1131的水流出口连通连接的出水管110,该出水管110收容于壳体10内。在本实施方式中,当出水管110收纳于壳体10内,出水管110和壳体10之间具有装配间隙,手持式高压清洗机1配置有阻断从所述装配间隙到壳体10的收纳腔106之间的通路的出水管密封件6,以将出水口1042和收容在壳体10内的工具电器件进行隔离。在一种可行实施方式中,出水管密封件6为挤压在出水管110和壳体10之间的密封圈。在另一种可行实施方式中,出水管密封件6也可以为通过灌胶形式形成的灌胶体。当然,在其他实施方式中,壳体10和出水管110之间的装配间隙还可以通过焊接形式填充。
此外,在本实施方式中,工具接线排14固定连接至壳体10的底部,工具接线排14和壳体10之间具有装配间隙,工具接线排14和壳体10之间设有工具接线排密封件(未图示),以阻止外部水流通过所述装配间隙流入至壳体10的收纳腔106内。在一种可行实施方式中,工具接线排密封件(未图示)为挤压在工具接线排14和壳体10之间的密封圈。在另一种可行实施方式中,工具接线排密封件也可以为通过灌胶的形式形成的灌胶体。当然,在其他实施方式中,壳体10和工具接线排14之间的间隙还可以通过焊接形式填充。
在本实施方式中,通过将半壳间的接合间隙密封、出水管110和壳体10之间的配合间隙密封以及壳体10和工具接线排14之间的装配间隙密封,以全方位封堵壳体10上存在的漏水口,防止水流进入壳体收纳腔106,导致收纳在壳体10内的工具电器件表面有水。
作为本公开实施例中对手持式高压清洗机1内工具电器件进行防水的第二种实施方式,如图14所示,本实施方式与上述实施例的区别在于:本实施例中的第一半壳101与第二半壳102的连接仅通过简单的机械连接方式进行紧固连接,例如卡扣、螺钉等,且第一半壳101与第二半壳102的连接处可以不设置防水密封结构。本实施例中的防水密封结构布置在壳体10的内腔内。具体的,手持式高压清洗机1还包括一防水密封箱体7,该防水密封箱体7收容在壳体10内。将壳体10内的工具电器件均置纳于该防水密封箱体7内。具体的,上述电机111、主体控制板12及电连接这些器件的导电件均容置于该防水密封箱体7内,以阻止水流与壳体10内的工具电器件相接触。
进一步的,上述收容于壳体10内的开关105可用于控制电机111进行工作,在一种可实施方式中,该开关105为按压开关,其包括供按压的按钮1051,当需要启动手持式高压清洗机1时,该按钮1051 可操作的被按压至启动状态,此时电机111旋转提供动力;当需要关闭手持式高压清洗机1时,该按钮1051可操作的被按压至释放状态,此时电机111能够在预设的时间内停止旋转。在此种实施方式下,为了便于开关105上的按钮1051可操作的被按压或释放,开关105不设置在上述防水密封箱体7内。为了避免水流通过第一半壳101与第二半壳102的结合的缝隙处进入壳体10内部,影响开关105的使用。此种实施方式下,开关105可以为防水开关。
当然,开关105也可与电机111、主体控制板12及电连接在上述电器件之间的导电件均位于防水密封箱体7内部。此种实施方式下,开关105为感应开关。当操作者需要启动手持式高压清洗机1时,操作者按压扳机13,此时感应开关能够感应到操作者的按压力,从而控制感应开关处于开启状态。
在本实施方式中,通过将收纳于壳体10内的工具电器件直接置于防水密封箱体7内,以防止水流进入壳体10的收纳腔106收纳腔106,导致壳体10内的工具电器件表面有水。
作为本公开实施例中对壳体10内工具电器件进行防水的第三种实施方式,如图16所示,在该实施方式中,壳体10的第一半壳101与第二半壳102的接合处不设有防水密封结构。收纳于壳体10内的主体控制板12的外周面均设有包裹层。该包裹层可通过灌胶的形式实现。进一步的,在本实施方式中,开关105为防水开关。电机111为高散热防水电机。此外,在本实施方式中,手持式高压清洗机1还包括电连接在上述电器件之间的导电件,具体的,导电件为若干线缆组件15。该等线缆组件15包括将工具接线排14电连接于主体控制板12的第一线缆组件151、将防水开关105电连接于主体控制板12的第二线缆组件152及将高散热电机111电连接于防水开关105的第三线缆组件153。各线缆组件15均包括防水接插件154、电性连接于防水接插件154一端的第一线缆155及电性连接于防水接插件154另一端的第二线缆156。两根线缆分别与相应的工具电器件电性连接。在本实施方式中,通过线缆组件15的设置即可在不拆卸的电器件的情况下将两个电器件进行电性连接。进一步的保证不破坏相应电器件本身的防水效果。
对于上述壳体内的工具电器件的三种防水实施例中,电池包2的位置有两种不同的设置方式。
电池包的第一种设置方式:如图13~16所示,电池包2完全容纳至壳体10内。换句话说,即电池包2不可拆卸的连接于壳体10。
此时,一种情况下,仅通过上述壳体10防水的第一种实施方式中提供方式,即将两半壳间的接合间隙密封以及出水管110和壳体10之间的配合间隙密封,即可实现电池包2和壳体10的防水。
另一种情况下,仅通过壳体10防水第二种实施方式中提供的方式,即将收容于壳体内的工具电器件及电池包2一起收容于防水密封箱体7内。具体的,电机111、主体控制板12、电池包2、电连接在上述电器件之间的导电件均收容于上述防水密封箱体7内。需要说明的是:同壳体10防水的第二种实施方式一样,可根据开关105的类型来选择是否将开关105设置在防水密封箱体7内。通过改变电池包2的位置,使得电池包2与壳体10的防水密封仅通过一步即可实现,不需要额外的对电池包2进行防水结构设置,防水结构更简单。需要说明的是,电池包2内置于壳体10内的实施方式,电池包可以理解为内置电池。
此外,由于电池包2收容于壳体10内,因此需要进一步考虑如何对电池包2进行充电。本发明提供了两种方案,一种方案是:如图15所示,在壳体10上设置与电池包2电信连接的防水充电接口16。通过该充电接口16为电池包进行充电。另一种方案是:如图14所示,电池包2进一步包括容置于安装腔 20内的无线充电组件(未图示)。手持式高压清洗机1进一步包括无线充电器17。需要说明的是,该无线充电器17可作为手持式高压清洗机1的一部分,也可作为一个附件。当将手持式高压清洗机1放置在无线充电器17上,该无线充电器17可与电池包2内的无线充电组件发生感应配合,以对电池包2进行无线充电。
电池包2的第二种设置方式,如图10~11和图17所示,电池包2可拆卸的连接于壳体10。即可理解为电池包2外置。此时还需要对电池包2上的带电体进行防水密封,以满足壳体10上的工具电器件和电池包2上的带电体均不接触水。
如下介绍当手持式高压清洗机1喷出的工作水压大于2.5Mpa,且与手持式高压清洗机1可拆卸连接的电池包2的电压大于42.4V时,本实施例中是如何对电池包2上的带电体进行防水的。
作为本公开实施例中对电池包2上带电体进行防水的第一种实施方式,首先,本公开实施例提供的电池包2的包盖21、包底22为分体结构。包盖21与包底22通过螺钉(未图示)紧固连接。而通过螺钉紧固连接,包盖21与包底22的连接处势必存在装配间隙。外界水流能够通过该装配间隙流入至电池包2的安装腔20内,导致各电芯231的两电极端上有水和/或电芯组23之间有积水,从而引起电池包2内电路短路,造成漏电、触电、甚至电芯爆炸等安全风险。因此,在本实施方式中,包盖21和包底22连接处需要做防水密封。具体的可参手持式高压清洗机1喷出的工作水压小于2.5Mpa,且与手持式高压清洗机1配接的电池包2的电压小于42.4V,以及手持式高压清洗机1喷出的工作水压大于2.5Mpa,且与手持式高压清洗机1配接的电池包2的电压小于42.4V时,电池包2防水的第四种实施方式中关于包盖21和包底22防水密封的方案(如图4所示),此处不一一獒述。
进一步的,电池包2上的连接脱扣装置26的防水密封方案也可参上述电池包2防水的第四种实施方式中关于连接脱扣装置26防水密封的方案(如图12所示),此次不一一獒述。
此外,当电池包2和手持式高压清洗机1配接,手持式高压清洗机1和电池包2之间具有配合间隙,为了避免收容于安装腔20内的电池包端子251、壳体端子142与外界水流接触。在本实施例中,如图9、10所示,手持式高压清洗机1和电池包2中至少一个配置有阻断从所述配合间隙到插接口27之间的通路的插接口密封件270。插接口密封件270能够将电池包端子251、壳体端子142与外界进行隔离,抑制外部水流通过配合间隙流入到电池包端子251和壳体端子142上。具体的,插接口密封件270连接在工具接线排14和电池包2的配合面211之间。关于插接口密封件270的连接,在一种可实施方式中,插接口密封件270连接在工具接线排上。具体的,如图9所示,插接口密封件270通过黏合剂与对接面140的至少部分相固定贴合。当电池包2安装至手持式高压清洗机1上,插接口密封件270构造成抵靠电池包2的配合面211并将电池包端子251、壳体端子142与外界进行隔离,以抑制外部水流通过插接口27进入至电池包2的安装腔20中。插接口密封件270可以通过黏合剂连接在对接面140上,也可以通过紧固件(未图示)或者其他任何可行方式连接在对接面140上。其中插接口密封件270可以为防水绝缘材料制成的可弹性变形的块状软垫。该块状软垫包括复数个贯通的开孔(未标示),这些开孔配备为以不妨碍块状软垫隔离插接口的构造供壳体端子142对应穿插。当然,插接口密封件270也可选择一体形成的条状密封圈(未图示)。密封圈圈设对接面140上,电池包2配接至手持式高压清洗机1后,插接口27位于条状密封圈围设的密封空间内。
当然,插接口密封件270也可以活动的设置在工具接线排14上,电池包2与手持式高压清洗机1 配接的过程中,能够带动插接口密封件270与工具接线排14的对接面140之间的距离发生变化,且至少有一种距离能够防止外部水流通过插接口27进入至安装腔20内。这里活动的设置可以理解为插接口密封件270与工具接线排14非固定式,插接口密封件270是可拆卸的。
关于插接口密封件270的连接,在另一种可行实施方式中,插接口密封件270与电池包2的配合面211相连接。当电池包2安装至手持式高压清洗机1上,插接口密封件270抑制外部水流通过插接口27进入至电池包2的安装腔20中。
作为本公开实施例中对电池包2上带电体进行防水的第二种实施方式,电池包2包括完全包覆电池包2的安装腔20内的带电体(除了电池接线排25)的防水透气结构8。具体的,电芯组23、电池包控制板24、电连接电芯组23和电池包控制板24的导电件均被防水透气结构8包裹。更具体的,防水透气结构8为独立的整体结构。即各带电体被防水透气结构8整体包裹。当然,独立透气结构也可为分体式结构,位于电池包2内的带电体也可以被分体包裹。
在一种可行实施方式中,如图7所示,所述的防水透气结构8为灌胶形式形成的灌胶体。在另一种可行实施方式中,如图8所示,该防水透气结构8为收容在安装腔20内的密封盒体。该密封盒体为防水材料制成。具体的,各带电体分别配置一个密封盒体,例如,电芯组23收容于电芯盒体81内,电池包控制板24收容于控制板盒体82内,显示装置29收容于显示装置盒体83内。当然,密封盒体也可以为独立的盒体。
此外,当电池包2和手持式高压清洗机1配接,手持式高压清洗机1和电池包2之间具有配合间隙,为了避免电池接线排25与外界水流接触。在本实施例中,手持式高压清洗机1和电池包2中至少一个配置有阻断从所述配合间隙到插接口27之间的通路的插接口密封件270。插接口密封件270能够将电池包端子251与外界进行隔离,抑制外部水流通过配合间隙流入到电池包端子251上。插接口密封件270的具体实施方案可参当手持式高压清洗机1喷出的工作水压大于2.5Mpa,且与手持式高压清洗机1可拆卸连接的电池包2的电压大于42.4V时,对电池包2上带电体进行防水的第一种实施方式中的介绍,此处不再重复说明。
作为本公开实施例中对电池包2上带电体进行防水的第三种实施方式,为了实现在不改变电池包2组成结构的情况下,使得电池包2既可通用于其它多种电动工具,又满足手持式高压清洗机1的防水要求。因此,如图17所示,本实施方式中,手持式高压清洗机1或电池包2可择一的连接有中空的防水套18,该防水套18包括套设于电池包2外围的袋体部181及供电池包2穿过的袋口部182。袋口部182的周边抵压于壳体10以与壳体10形成密封。当电池包2与手持式高压清洗机1插接配合,防水套18连接于壳体10,且与所述壳体10形成一个密封空间,上述电池包2收容于该密封空间内。这里防水套18的设置,即可理解为为电池包2穿上一防水套鞋。此时,一方面,仅需要对高压清洗机1的壳体10进行防水密封,不需要额外的对电池包2进行防水结构设置,高压清洗机1的防水密封也仅通过一步实现,防水结构更简单;另一方面,电池包2结构未作任何改变,电池包2可通用于其它电动工具。
进一步的,上述对于收容在高压清洗机1壳体10内的相应电器件实施防水的第一种和第二种实施方式,均是将相应的电器件放置于密封的空间内。为了保证电机111的散热需求得到满足,本发明对于电机111的散热提出了三种实施方式。
作为电机111散热的第一种可实施方式为,如图18所示,手持式高压清洗机1进一步包括包覆在电 机111外围的散热垫19。该散热垫19抵持在电机111与壳体10之间,以助于将电机111的热量通过散热垫19传递至壳体10。优选的,整个壳体10或者至少与电机111相对应区域的壳体10为高散热材料制成。具体的,高散热材料可以为铝。如此设计的好处在于,可实现电机111快速冷却,使得电机111不会被烧坏,延长电机111的使用寿命。
作为电机111散热的第二种可实施方式,如图19所示,高压清洗机1包括配置在电机111周围的第一散热系统114。该第一散热系统114包括能够旋转产生气流的风扇1141、散热管1142以及将散热管1142支撑于电机111外围的支撑架1143。其中所述风扇1141也可为电机111自带结构。优选的,散热管1142为螺旋状,其在周向上环设于电机111的外围。在此实施方式中,散热管1142通过支撑架1143与电机111间隙设置。散热管1142包括与手持式高压清洗机1的入水口1041相连通的第一管口1144及与泵113的水流进口相互连通的第二管口1145。外界水流自入水口1041流至散热管1142内,并自散热管1142的第二管口1145流出至泵113体内。当手持式高压清洗机1处于工作状态时,电机111带动风扇1141转动,并通过风扇1141转动产生的气流将电机111的热量传递至散热管1142。通过水流在散热管1142的第一管口1144与第二管口1145之间连续流动,以保证手持式高压清洗机在工作状态下,能够持续的为电机111进行散热。当然,散热管1142也可不设置为螺旋状,可配置为周向圈设于电机的外围的若干个散热管1142。各散热管1142之间可相互连通也可不相互连通。只要保证各散热管1142一端的管口与手持式高压清洗机1的入水口1041连通,各散热管1142另一端的管口与高压清洗机1的泵113的水流进口连通即可。换句话说,即保证散热管1142内的水为连续不断流通的冷却水。进一步的,与手持式高压清洗机1的入水口1041相连通的管口也可不止一个。进一步的,为了确保散热管1142内的冷却水能够带走电机111的热量,实现快速散热。散热管1142与电机111之间的直线距离不大于20厘米。
作为电机111散热的第三种可实施方式,如图20所示,手持式高压清洗机1包括配置在电机111周围的第二散热系统115。第二散热系统115包括与泵113相连接的散热片1151、与散热片1151相连接的冷凝管1152。冷凝管1152包括缠绕于电机111外表面的第一冷凝管1153及连接在第一冷凝管1153与散热片1151之间的第二冷凝管1154。在此实施方式中,为了保证导热散热达到最佳效果,第一冷凝管1153与电机111外表面直接接触,散热片1151也与泵113的外表面直接接触,即可理解为第一冷凝管1153贴覆于电机111的外周,散热片1151贴覆于泵113的外周。优选的,第一冷凝管1153为螺旋状。为了增大第一冷凝管1153与电机111的接触面,以更好的导出电机111的热量,在本实施方式中,冷凝管1152的剖面为方形。如下详细介绍冷凝管1152的导热散热原理。进一步的,冷凝管1152包括中空的内腔(未图示)、紧贴内腔壁的多孔毛细芯层(未图示)以及位于内腔内能够充满多孔毛细芯层的工作液体。所述内腔可操作的设置为负压。冷凝管1152靠近散热片1151的一端配置为冷却端1155,靠近电机111的一端配置为蒸发端1156。当电机111处于启动状态,蒸发端1156受热,多孔毛细芯层中的工作液体蒸发汽化,蒸汽在微小的压差下流向冷却端1155,并在冷却端1155放出热量凝结成冷却液体。该冷却液体再沿多孔毛细芯层流回蒸发端1156。如此循环,将电机111的热量不断地从蒸发端1156传递至冷却端1155,以对持续的对电机111进行散热。
作为电机111散热的第四种可实施方式,如图21所示,高压清洗机1包括配置在电机111周围的第三散热系统116。该第三散热系统116包括能够旋转产生气流的风扇1161、散热片组件1162以及与连接于散热片组件的水管支路1160。其中所述风扇1161也可为电机111自带结构。散热片组件1162包括支 撑件1163及连接于支撑件1163的若干散热片1164。在本实施方式中,水管支路设有两支,两支水管支路可呈180度对称设置。两支水管支路与支撑件穿插设置。每支管路的一端与入水口1041连通连接,每支管路的另一端与泵的内腔连通连接。通过冷却水流在每支管路内连续流动,以保证散热片组件温度降低。当高压清洗机1处于工作状态时,电机111带动风扇1161转动,并通过风扇1161转动产生的气流将电机111的热量传递至散热片组件1162,以实现对电机111进行散热。
以上所述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本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。
