US-7805803-B2用于吸尘器吸嘴显示灰尘流量。
专利摘要
一种用于真空吸尘器的吸嘴，可连接到真空吸尘器的吸管和/或吸入管，包括可通过管状连接部分连接到吸管或吸入管的喷嘴部分。灰尘传感器布置在真空吸尘器的流动路径中，其信号由可由低压开关激活的电池供电的电子控制装置评估。在操作期间，所述控制装置控制显示灰尘流的显示装置。控制装置、低压开关、显示灰尘流的显示元件以及用于接收电池的电池仓布置在形成于管状连接部分上侧的壳体中。灰尘传感器布置在壳体下方，连接部分的上部区域内，在灰尘气流中。
Original abstractA suction nozzle for a vacuum cleaner that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner includes a nozzle part that can be connected to the suction pipe or the suction tube by means of a tubular connection part. A dust sensor is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device displaying the dust flow. The control device, the low-pressure switch, the display elements displaying the dust flow, and a battery compartment for receiving the batteries are arranged in a housing formed on the upper side of the tubular connection part. The dust sensor is arranged beneath the housing, inside the upper region of the connection part, in the dust air stream.
