Zusammenfassung:The invention relates to a suction module (2) for a hand-held power tool (1), which suction module (2) has a motor-driven fan wheel (17), an intake channel (21) for sucking in dust-laden air, and a collecting container (23) for dust. A flow sensor (24) has a sensor surface (25), which is formed of plastic and is arranged in the intake channel (21), an electric field meter (26) facing the sensor surface (25) for determining the electrostatic field strength on the sensor surface (25), and an evaluating unit (27) for determining a flow rate of dust-laden air on the basis of the determined electrostatic field strength. 本发明涉及种用于手持式工具设备(1)的吸尘模块(2),其具有马达驱动的风扇叶轮(17)、用以抽吸含尘空气的抽吸通道(21)和用于灰尘的收集容器(23)。流量传感器(24)具有由塑料构成的且设置在抽吸通道(21)内的传感器面(25)、朝向所述传感器面(25)的用以确定该传感器面(25)上的静电场强度的电场测量计(26)和用以基于所确定的静电场强度来确定含尘空气的流量的分析处理单元(27)。
