在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据实际情况理解上述术语在本公开中的含义。
图2和图3为根据本公开的一个实施例的身体清洁头的剖面结构示意图；参照图2和图3，根据本实施例中的身体清洁头，包括：外壳1，外壳1开设有吸气口11，外壳1内设有与吸气口11连通的回流通道12；水管组件2，水管组件2设置于回流通道12内，水管组件2包括固定设置于外壳1内的水管支架21，水管支架21内配合穿设有出水软管22，出水软管22靠近吸气口11的一端伸出水管支架21设置，且伸出端套设有弹性体23和滑套24，弹性体23位于水管支架21与滑套24之间，滑套24可相对于水管支架21轴向移 动；当清洁头吸气时，回流通道12内的气流可推动滑套24向靠近水管支架21的方向移动并挤压弹性体23，使弹性体23沿出水软管的径向的尺寸变大，从而挤压出水软管22，使出水软管22的与弹性体23相对应的部分的内径变小，当吸气口的气压由大变小时，滑套24可向远离水管支架21的方向移动，使弹性体23沿出水软管的径向的尺寸减小，从而使出水软管22的与弹性体23相对应的部分的内径增大。
本公开实施例提供的身体清洁头，包括外壳1和水管组件2，当开始使用时，同时进行出水和抽气，此时，参考图4，当清洁头还未接触皮肤时，回流通道12的气压最大，和大气压相同，回流通道12内的气流沿图中向下的箭头方向流动，可推动滑套24向靠近水管支架21的方向移动到最大并挤压弹性体23，使弹性体23沿出水软管的径向的尺寸变大，从而挤压出水软管22使其形变达到最大，使出水软管22与弹性体23相对的部分内径变到最小，出水软管22处于关闭状态，因此，在未接触皮肤时，清洁头不会喷洒出水。在出水软管22中的水压恒定的前提下，出水口的喷水距离同时与出水口截面积以及吸气口11的压力有关系，因此，当吸气口11的压力不稳定时，可以通过改变出水口的截面积来保证出水口的喷水距离，参考图3，当清洁头接触皮肤时，抽气时会有比较大的阻力，回流通道12的气压比大气压小，作用在滑套24上的压力减小，滑套24的移动的位移量减小，同时，弹性体23的形变量减小，出水软管22的与弹性体23相对应的部分内径变大，出水软管22打开，出水软管内的水沿图中向上箭头方向流动并喷洒出来对皮肤进行清洗。在清洗的过程中，抽气效力时大时小，当抽气效力增大时，回流通道12内的压力增大，因而滑套24的位移量和弹性体23的形变量也均增大，出水软管与弹性体23相对的部分的内径变小，清洁头的出水速度变快，即随着抽气效力的增大清洁头的出水速度加快，因此可以避免出现抽气效力增大时出水管的水没有到达皮肤便被抽走的问题；当抽气效力减小时，回流通道12内的压力减小，因而滑套24的位移量和弹性体23的形变量也均减小，出水软管与弹性体23相对的部分的内径变大，清洁头的出水速度变慢，即随着抽气效力的减小清洁头的出水速度减慢，因此可以避免出现抽水效力减小时清洗完皮肤的脏水不能及时被抽走的问题。清洗完成后，把清洁接头拿离皮肤时，回流通道12的气压恢复到和大气压相同，水不会喷洒到任何地方。因 此，只要同时进行出水和抽气，身体清洁工具还可以根据清洁头是否与皮肤接触自动调节出水软管22的开闭。
滑套24可以为圆柱形套或锥形套，采用圆柱形套时受力面积仅为圆柱形底面，因此为方便滑套24受力移动。在本公开的一个实施例中，滑套24为锥形套，且直径较小的一端靠近外壳1的吸气口11设置，回流通道12的压力作用于直径较小的一端，该端底面以及锥形侧面均可以受力，增大了受力面积，使滑套24更容易在压力的作用下移动。
为使弹性体23在工作时更稳定，在滑套24内壁开设有环槽241，弹性体23设置于环槽241内，水管支架21的端部伸入环槽241内且与弹性体23相抵靠，弹性体23可被牢牢扣在环槽241里，保证了弹性体23在工作时的可靠性。在本公开的一个实施例中，弹性体23可采用橡胶材料制作。
弹性体23可以为分布在环槽241内的多个弹性块状体，弹性块状体可以为球形或方块形等；弹性体23也可以为单个弹性圆环。在一个实施例中，为保证弹性体23在工作中的稳定性，弹性体23为弹性圆环，此时，为避免弹性圆环受压时出现反应延迟，环槽241的最大直径与弹性圆环的外径相适应，滑套24一旦产生位移量，弹性圆环便可即刻产生形变量并作用于出水软管22，保证了出水速度及时随着随抽气效力变化而变化，从而保证了清洁效果。
为保证出水软管22的出水口喷洒的水在被吸走之前有足够的时间清洗皮肤，出水软管22的出水口应位于外壳1内，且外壳1的吸气口11与出水软管22的出水口沿轴向间隔一定距离设置。
在本公开的一个实施例中，外壳1的吸气口11与出水软管22的出水口沿轴向间隔的距离应小于或等于出水口的喷水距离，这样在使用时水才能以恰当的力道喷洒到皮肤上。
为避免出水口的喷水距离过远，水速过快，在清洗皮肤时给人体皮肤造成不适，外壳1的吸气口11与出水软管22的出水口沿轴向间隔的距离与出水口的喷水距离的差值不能太大，例如为1-2cm。
本公开的至少一个实施例还提供了一种身体清洁工具，包括供水电机(图中未示出)和抽气电机(图中未示出)，还包括上述任一实施例所述的身体清洁头，供水电机与出水软管22连通，抽气电机与身体清洁头的回流通道12连通，抽气电机可将外部空气以及出水软管22喷出的水流通过回流通道 12抽入清洁工具内部。
在恒定的水压以及有限的形变量两个条件限制下，出水速度有一定范围，因此，相应的抽力的大小也应有一定的范围限制，如果抽力过大，出水软管22总是处于关闭状态；如果抽力过小，出水速度过快，在清洁时有可能给人带来不适感，而且喷出的水也有可能回收不完全。所以在选择弹性体23时，弹性体23的弹性系数要与抽气电机功率和供水电机功率相匹配。
关于本公开实施例的身体清洁工具的其他构成部件等已为本领域的技术人员所熟知，在此不再详细说明。
在本公开中的描述的特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
本申请要求于2014年9月22日递交的中国专利申请第201410486475.6号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
