    • This invention relates to a filter change indicator that is operable in various orientations of the device incorporating it. For example, the filter change indicator is operable when the device is positioned in either the upright or sideways position. The device incorporating the filter change indicator can be any air moving device which incorporates a cleanable or replaceable filter. The filter change indicator includes a transparent viewing window and a tubulation. The viewing window displays a visible signal when the filter needs changing. The visible signal can be a float retained in the tubulation. The tubulation is a hollow transparent tube which forms an incline plane within the housing. The tubulation includes a first end, a second end and a step. The first end is in fluid communication with an air flow path through the tubulation, and this air flow path is exposed to atmospheric pressure. The second end opens into an air flow path formed between the inlet and outlet at a location downstream of an air filter. When a predetermined pressure differential develops across the tubulation, a predetermined force develops inside the tube which lifts the float from the first end of the tubulation to a position at the second end. The lifting force causes the float to come to rest in the tubulation at a position adjacent the viewing window.
    • 本发明涉及一种过滤器更换指示器,其可在包含该装置的装置的各种取向中操作。 例如,当设备位于直立或侧向位置时,过滤器更换指示器是可操作的。 装有过滤器更换指示器的装置可以是包含可清洁或可更换过滤器的任何空气移动装置。 过滤器更换指示器包括透明的观察窗口和管道。 当过滤器需要更改时,查看窗口显示可见信号。 可见信号可以是保持在管状体中的浮子。 该管状是在壳体内形成倾斜平面的中空透明管。 该细管包括第一端,第二端和台阶。 第一端与通过管道的空气流动路径流体连通,并且该空气流动路径暴露于大气压力。 第二端在空气过滤器下游的位置处形成在入口和出口之间形成的空气流路。 当预定的压力差跨越管道形成时,在管内形成预定的力,其将浮子从管状体的第一端提升到第二端的位置。 提升力导致浮子在与观察窗相邻的位置处在管状体中静止。
