Residual liquid quantity detecting method
Abstract:
A residual liquid quantity detecting method capable of accurately detecting the residual quantity of liquid without relying upon visual observation, preventing overfill at the time of refilling. A residual liquid quantity detecting method for a liquid supply container (100) has a container body (108) having a liquid supply opening (126) and has a liquid storage chamber (118) in which liquid (119) is sealed, the liquid storage chamber (118) being formed in the container body (108) and communicating with the liquid supply opening (126). The liquid (119) is supplied from the liquid supply opening (126) to the outside of the container by primary supply pressure generated through reduction, by pressure, in volume of the liquid storage chamber (118). The residual quantity of the liquid (119) in the liquid storage chamber (118) is detected by detecting primary supply pressure of the liquid (119).
Abstract(Chinese):

一种残留液量检测方法，其能够在不依赖目视观察的情况下精确地检测液体的残留量，防止再填充时的过量填充。 液体供给容器（100）的残留液量检测方法具有：具有液体供给口（126）的容器主体（108），并具有密封液体（119）的储液室（118） 室（118）形成在容器主体（108）中并与液体供应开口（126）连通。 液体（119）从液体供应开口（126）通过压力通过压力在液体储存室（118）的体积中产生的初级供给压力从液体供应开口（126）供应到容器的外部。 通过检测液体（119）的一次供应压力来检测液体储存室（118）中的液体（119）的剩余量。
