实施例2
本发明实施例1的一种浮力驱动恒量液体抽取器可应用于往抽水马桶水箱中自动投放清洁剂，液体箱6为常用抽水马桶水箱，第一液体7为水，储液盒4内盛装的第二液体8为清洁剂，浮子1的体积约250-300cm 3，浮子内加上配重使浮子1总重约125-150g，根据浮力计算公式，浮子1浸没在水中时所受到的浮力约为250-300g，浮力大于重力，浮子1在水中上浮，上浮行程设定约3-5cm，最高位时受到连接杆的阻止，杠杆机构中动力臂21和阻力臂22的臂长比为2-3，可将浮子1的合力放大2-3倍作用至活塞31，浮子1上升，活塞31下降，清洁剂被吸入到液体投放腔室41，水位下降时清洁剂被投放至抽水马桶水箱中与水混合，这样可以往抽水马桶水箱内自动定量地投放清洁剂，清洁剂投放浓度均匀，可有效解决现有的马桶清洁剂使用时存在的前期浓度高、后期浓度低、前后效果不一的问题，同时清洁路径宽，清洁覆盖面广，能有效减少清洁剂浪费。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。

  5. 根据权利要求4所述的一种浮力驱动恒量液体抽取器，其特征在于，所述杠杆机构包括固定的支点以及活动连接在支点两侧的动力臂和阻力臂，所述动力臂通过连接杆与浮子连接，所述阻力臂连接活塞。
  6. 根据权利要求5所述的一种浮力驱动恒量液体抽取器，其特征在于，所述动力臂与阻力臂的臂长比为2-3。
  7. 根据权利要求1所述的一种浮力驱动恒量液体抽取器，其特征在于，所述吸液管的出口处设置有第一单向阀。
  8. 根据权利要求1所述的一种浮力驱动恒量液体抽取器，其特征在 于，所述出液口处设置有第二单向阀。
  9. 根据权利要求1所述的一种浮力驱动恒量液体抽取器，其特征在于，所述储液盒上设置有用于往储液盒内添加第二液体的加液口，所述加液口上盖设有加液口盖。
  10. 根据权利要求1-9中任一所述的一种浮力驱动恒量液体抽取器的使用方法，其特征在于，所述使用方法包括：
    浮子外部的第一液体液面处于低位时，浮子位于第一液体液面以上，浮子在重力作用下同样处于低位；
    第一液体液位升高并淹没浮子，由于第一液体的平均密度值大于浮子的平均密度值，浮子所受到的浮力大于浮子的重力，浮子上浮，浮子上浮过程受到的合力通过驱动力放大机构放大后驱动活塞在活塞套筒内滑动产生吸力，将第二液体由吸液管内定量吸取至活塞套筒内；
    第一液体液位下降至不再淹没浮子，浮子在重力作用下回落，浮子下落过程受到的合力通过驱动力放大机构放大后驱动活塞在活塞套筒内滑动回复并产生推力，同时将被吸取的第二液体由出液口排出储液盒外；
    重复上述过程，第一液体液位的每一次上升和下降，均将第一液体对浮子的合力转化为第二液体抽取和排放的驱动力，实现对储液盒内的第二液体进行自动定量地抽取和排放。
