Suzhou KingBow Electric Appliance Co., Ltd

A household vacuum cleaner is a cleaning appliance that utilizes an electric motor to generate negative pressure to suck up dust and debris. It primarily consists of a series-excited commutator motor, a centrifugal fan, a dust filter, and vacuuming accessories. Its working principle involves the motor driving the impeller to rotate at high speed, creating a partial vacuum. This utilizes the pressure difference between the inside and outside air to draw dust into the machine along with the airflow. The dust is then separated by the dust filter and stored in the dust collection chamber, while the clean air is discharged after undergoing multilevel filtration. The core components include the series-excited commutator motor, a cyclone separation system, and a detachable dust collection box, equipped with a HEPA filter to achieve 99.97% filtration of 0.3 micron particles. The equipment is categorized into three types based on its form: barrel-type, horizontal-type, and handheld-type, each suitable for cleaning large areas, furniture, and narrow spaces respectively. Modern products are equipped with cyclone separation technology to prevent suction force attenuation, and some models adopt a sealed filtration system to avoid secondary pollution. High-end models are equipped with laser detection and piezoelectric sensors to achieve dust visualization and intelligent suction force adjustment. The vacuuming range covers multiple scenarios such as floor cleaning, high-altitude dust removal, and fabric maintenance, and can handle pollutants such as dust, allergens, and pet hair.
