吸尘器工作一段时间后,机内滤尘器和集尘袋内聚积有相当多的杂物尘埃,若不及时清除,将会堵塞风道,降低吸力。用气压传感器来检测机内积尘状况,是近期吸尘器产品开发中采用的一项新技术。气压传感器有着检测灵敏度高、体积小,安装调试方便等特点,因此在开发具有声、光报警功能和智能型吸尘器新品中,有着广泛的应用前 Vacuum cleaner work for a period of time, the machine filter and dust bag accumulation of a considerable amount of debris dust, if not removed in time, will block the air duct and reduce suction. Air pressure sensor to detect the status of dust inside the machine is the recent vacuum cleaner product development used in a new technology. Barometric pressure sensor with high sensitivity, small size, easy installation and debugging features, so the development of a sound, light alarm function and intelligent vacuum cleaner new products, has a wide range of applications before
