除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术
领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示,本实施例公开了一种手持式压力清洗机100,该手持式压力清洗机100可将进水口与水源通过水管进行连接,水流经过手持式压力清洗机100向外喷射具有一定压力的水流,并将该具有一定压强的水喷射到物品表面上已达到清洗的效果。
上述手持式压力清洗机100包括壳体110、驱动部件120、控制部件130及电源接口140,该壳体110包括喷射部111及手持部112,在本实施例中手持部112即为用于握持的手柄,其形状大致为枪把手,尺寸为10厘米左右,适合单手握持。当然手持部112也可以为D字形手柄。并且整个手持式压力清洗机100的中心位于手持部112的位置,当使用者单手握住手持部112时,即可掌握整个手持式压力清洗机100。上述驱动部件120、控制部件130设置在上述壳体110内,驱动部件120包括电机、连接电机的传动机构及受传动机构带动的泵。出于手持便携性的要求,压力清洗机100本身不具有用于存储水源的水箱,而是通过水管连接至外部水源,外部水源可以是池塘、水龙头等。
上述电机、连接电机的传动机构及受传动机构带动的泵位于壳体110内,上述泵可以为一柱塞泵、齿轮泵或隔膜泵等。该泵一般包括进水口及出水口,进水口的一端通常通过进水管与水源(如:水桶或自来水的出水口)连接,另一端泵的出水口则连接上述壳体110的出水口,用于向外喷射水流。在壳体110的出水口一般还连接有喷头,一般的该喷头与壳体110的出水口可拆卸的连接,壳体110的出水口可以通过外接不同的喷头附件的形式以调节水喷出。例如壳体110的出水口上连接花洒,这样可以便于洗澡。并且可以在壳体110的适当的位置设有悬挂机构。需要时,将喷头悬挂在悬挂机构上,然后将悬挂机构可调节的伸展至高处,以进一步方便洗澡。悬挂机构可以是常见的环形圈或者卡勾等。在其他实施例中,还可以在壳体110上安装按摩用的喷头,这样喷头出水比较柔缓,适合对操作者进行水浴按摩。另外还可以在壳体110的出水口外接尖角锥,水从尖角锥的头部喷出,这样使出水的速度更快,压强也更强。当
然,还可以在壳体110的外接长线性的出水条,从出水条喷出的水可以形成水幕,或者外接形成特殊形状的喷头,例如花形、桃形、心形等。喷头的附件并不限于上述列举。
控制部件130用于控制电机进行工作,具体地,控制部件130和电机之间通过电线连接。控制部件130可包括一控制开关,设置在壳体110的手持部112的一侧,使用者在握住手持部112的同时,通过控制开关控制驱动部件的电机进行工作,操作者要改变电机的运转状态时,操作者操作控制开关,从而使控制开关将电路导通,控制部件可以改变马达的运转状态。这里的改变马达的运转状态可以是改变马达的运行参数,例如马达的功率、马达的转向等。上述控制开关可以采用多级调节的方式控制电机进行高低速工作,例如控制开关可以为拨钮,拨钮具有高中低多个不同的档位,操作者根据需求进行相应的档位选择,当然,控制开关也可以是按钮的形式,按下去即表示开启。可以是旋钮的形式,操作者旋动旋钮使其启动。控制开关也可以是无级的调节方式,例如控制开关是旋钮,旋钮可以绕圆周或者半圆的位置任意的调节。控制开关还可以是联动安全开关以提高操作安全性。
本发明提供的压力清洗机100重量轻、体积小,可实现随身携带、清洁各类物品。
在本实施例中,压力清洗机100的整机重量小于等于3公斤,在可选的实施方案中,整机重量小于2.8公斤、2.5公斤、2公斤、或1.8公斤、或1.7公斤、或1.5公斤。较轻的重量使得压力清洗机100能够被长时间手持进行清洁工作。
为了提高便携性,在本实施例中,压力清洗机100的整机长度小于500毫米,优选的,整机长度400毫米或350毫米。当采用不同长度的喷头时,压力清洗机100的整机长度会有所变化,如采用长枪喷头时,压力清洗机100的整机长度可达到1000毫米。优选的,压力清洗机100不加任何喷头时,压力清洗机100的本体的长度小于300或250毫米。压力清洗机100的整机高度小于250毫米或200毫米,整机宽度(不包括电池包和外部驱动电源)小于150或100毫米。
进一步的,传动机构包括减速结构,如行星齿轮机构等。在泵及其配套的旋转-往复转换结构的输入转速范围一定的情况下,相比直接采用输出转速在该
输入转速范围内的低转速电机,采用减速结构和高转速电机的合理配合能够显著降低电机和传动机构的整体重量和体积。在本实施例中,电机的空载转速大于等于10000rpm或12000rpm或15000rpm或20000rpm,传动机构的减速结构的空载输出转速小于等于3000rpm或2500rpm或2200rpm或2000rpm。传动机构的减速结构的减速比在12:1至3:1之间,如约10:1、8:1、7:1、6:1、5:1、4:1等。相较直接使用低转速电机,本实施例的电机的体积和重量都能够降低至一半以下,进一步提高了压力清洗机100的便携性。
该手持式压力清洗机100包括电源接口140。电源接口140一般设置在壳体110的手持部112的一端,即设置在手持部112的与连接部111相对的一端,这样当电源接口140外接驱动电源时,用于连接驱动电源的电线不会干扰操作者对手持式压力清洗机100的操作。这里的电源接口140可以包括用于外接电池包200的电池包接口142及连接外部驱动电源(未图示)的外接电源接口141。其中,外接电源接口141用于外接0~60V的驱动电源,优选的,外接电源接口141用于外接0~18V的外部驱动电源。当外接电源接口141外接外部驱动电源(例如车载电源)时,外部驱动电源可通过外接电源接口141向设置壳体110的电机供电,使电机驱动泵进行工作,进而使手持式压力清洗机100进行工作;另一方面,当电池包200接口142外接电池包200时,电池包200可通过电池包200接口142向设置在壳体110内的电机供电,使电机驱动泵进行工作,进而使手持式压力清洗机100进行工作。
由于本发明提供的手持式压力清洗机100至少包括2个电源接口。因此,为了避免在手持式压力清洗机100在正常工作时,外部驱动电源及电池包200同时对电机进行供电,进而对手持式压力清洗机100造成伤害。因此,电池包200与外部驱动电源需择一的与电机进行电性连接。换句话说,即电池包200与外部驱动电源只能有一个与电机进行电性连接。
如图2所示,作为本发明的第一优选实施例,电池包200安装至电池包接口142时,电池包200至少部分遮蔽外接电源接口141。具体的,可将这里的外接电源接口141设置在紧邻电池包200接口142的一侧,当电池包200接口142外接电池包200后,电池包200所占用的空间至少部分覆盖外接电源接口141,
这样便对外接电源接口141接入外部驱动电源造成了干涉,使外接电源接口141无法连接外部驱动电源;同理,当外接电源接口141外接外部驱动电源后,因外部驱动电源所占用的空间至少部分覆盖电池包200接口142的空间,这样便造成外接电源接口141对电池包200接口142的接入形成了干涉,使电池包200接口142无法与电池包200进行对接,这样便避免了电池包200及外部驱动电源同时接入电源接口上,进而对手持式压力清洗机100造成伤害。
当然,如图3所示,本发明第二优选实施例可以在这里的外接电源接口141及电池包200接口142之间设置一切换单元,该切换单元可控制上述外接电源接口141及电池包200接口142中的其中一个对电机进行供电。具体地,该切换单元可以为双向切换开关,当操作者需要通过外接电源接口141外接外部驱动电源时,操作者操作该切换开关,使该外接电源接口141处于可接通的状态,而使电池包200接口142处于不可接通的状态,这样驱动电源便可通过上述外接电源接口141与控制部件130及驱动部件120接通,而电池包200便无法通过电池包200接口142对驱动部件120供电。
当然,如图4~5所示,作为本发明的第三优选实施例,电池包200安装在电池包接口142时所占据的安装空间与外部驱动电源安装入外接电源接口141所占据的安装空间不存在重合区域。换句话说,即电池包接口142与外接电源接口141分开设置在手持式压力清洗机100的不同位置,当电池包200安装在电池包接口142时,电池包200无法对外接电源接口141进行遮蔽。同理的,当外部驱动电源安装在外接电源接口141时,外部驱动电源也无法对电池包接口142进行遮蔽。此时,需要避免电池包200与外部驱动电源的连接位置发生错误,而造成手持式压力清洗机无法正常工作,且增加操作者的操作步骤。作为可选的实施例,可通过将电池包接口142与外接电源接口141配置为不同形状,以避免电池包200与外部驱动电源产生误插。即避免出现电池包200***至外接电源接口141,外部驱动电源***至电池包接口142,而影响手持式压力清洗机100的正常工作。作为另一可选实施例,如图5~6所示,可通过在手持式压力清洗机100上配置识别模块150,优选的,识别模块150为2个。2个识别模块150分别设置在对应的电池包接口142与外接电源接口141处。当电池
包200和/或外部驱动电源连接至电源接口140时,该识别模块150可用于识别电池包200和/或外部驱动电源,手持式压力清洗机100根据识别模块150的识别结果可操作的控制外接电源接口141或电池包接口142是否能够与电机形成电性连接。进一步的,手持式压力清洗机100还包括控制模块160,控制模块160与识别模块150相连接并用于接收识别模块150根据识别结果发送的相应信号,根据接收到的信号控制外接电源接口141或电池包接口142是否能够与电机形成电性连接。以上可用来识别电池包200与外部驱动电源中的任意一个是否与相应的电源接口140连接正确。需要进一步注意的是,这种电池包200安装空间与外部驱动电源安装空间不存在重合区域的实施例,往往会出现一种情况,即电池包200与外部驱动电源都连接至对应的电源接口140,且电池包200、外部驱动电源与电源接口140的连接均正确,这时,为了节省电池包200的能量,可以控制外部驱动电源优先进行供电。具体的,当电池包200连接至电池包接口142,且外部驱动电源连接至外接电源接口141时,手持式压力清洗机100可操作的控制外部驱动电源与电机形成电性连接,且控制电池包200与电机断开。
根据实验表明,一般电池包200的额定电压不高于36伏特可以满足对电机提供能量的要求,并且由于人体安全电压是36伏,因此,在上述实施例中,额定电压不高于36伏有助于提高安全性,防止触电等危险情况的产生。在优选的实施例中,外部驱动电源与电池包200的额定电压可以是7.2伏特、9.6伏特、10.8伏特、12伏特、15伏特、18伏特。
进一步的,为了满足电池包200与外部驱动电源中的一个能与电机形成电性连接,并满足电机的能量需求,具体的可以理解为:电机能够提供驱动力驱动手持式压力清洗机100向外喷射一定压力的水流,并将该具有一定压力的水喷射到物品表面上实现达到清洗的效果。需要对连接至电池包接口142的电池包200及连接至外接电源接口141的外部驱动电源的额定电压有限制。作为本发明的优选实施例,电池包200的额定电压需配置在电机额定电压的±10V范围内。同样的,外部驱动电源的额定电压需配置在电机额定电压的±10V范围内。
下面可通过电池包200来举一例说明,当电机的额定电压为20V时,连接
至电池包接口142的电池包200的额定电压可为10V~30V。在此范围内,电池包200是可以提供足够的能量给电机,使得电机驱动手持式压力清洗机100向外喷出具有清洗压力的水流。而若电池包的额定电压小于10V,电池包200也可以与电机实现电性连接,但是电池包200提供的能量无法实现电机驱动手持式压力清洗机100向外喷出具有清洗压力的水流,致使手持式压力清洗机无法正常工作。
此外,外部驱动电源可以为车载电源,电池包200可以是锂电池或者镍镉电池等,这样电池包200的体积就会比较小,从而有利于提高整个手持式压力清洗机的便携性。在本实施例中,电池包200的体积不大于3立方分米。在优选实施例中,电池包200的体积为1立方分米左右。在本发明中,电池包200可为插拔式或固定式,以便于将电池包200从设备上拆卸下来,进行充电或者更换。
上述手持式压力清洗机100通过外接电源接口141外接外部驱动电源,通过该外部驱动电源(例如车载电源)驱动手持式压力清洗机进行工作,这样工作人员不具备家用220V交流电的情况下,可通过外部驱动电源使手持式压力清洗机100进行工作,也使该手持式压力清洗机100无需装配电池便可以工作,进而提高了该手持式压力清洗机的便携性。
以上所述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。
