    • A water purifier includes a first reservoir, a second reservoir having an outlet through which filtered water can be dispensed, and a pump for pumping water from the first reservoir to the second reservoir. Water passes through a filter from the first reservoir en route to the second reservoir upon activation of the pump. There is a first water level detector in the first reservoir and a second water level detector in the second reservoir. A switch co-operates with the second water level detector to activate the pump when a reduced water level is detected in the second reservoir by the second water level detector. The switch also co-operates with the first water level detector to deactivate the pump, should the first water level detector detect a low water level in the first reservoir. A single switch performs both tasks.
    • 净水器包括第一储存器,第二贮存器具有可以分配过滤水的出口,以及用于将水从第一储存器泵送到第二储存器的泵。 泵激活后,水通过过滤器从途中的第一储存器到第二储存器。 在第一储存器中存在第一水位检测器,在第二储存器中存在第二水位检测器。 当第二水位检测器在第二储存器中检测到降低的水位时,开关与第二水位检测器协作以启动泵。 如果第一水位检测器检测到第一储存器中的低水位,则开关还与第一水位检测器配合以停用泵。 单个交换机执行两个任务。
