摘　　要：现有市面上的地刷设计,可分为无滚刷、单滚刷、多滚刷。无滚刷主要用于附件,或卧式吸尘器。单滚刷由于其结构简单,成本低,在地板及地毯均能做到较好的清洁能力,是目前的主流设计。多滚刷中双滚刷居多,例如Shark的Duo-cleaning设计,Dyson的Double Fluffy^(TM )cleaner head设计。无论是单滚刷还是多滚刷,大部分只能满足向前推动时的大颗粒灰尘或堆叠灰尘吸入。后拉时大颗粒灰尘容易堆叠。为了提高地刷吸入口的真空度,地刷吸口后侧设有密封结构,密封结构一般是绒毛条或帆布条、橡胶条等柔性材料,这些材料与地面有1 mm左右的过盈以增加密封。但是这种设计存在弊端,在地刷回拉时,由于地刷吸口后侧密封结构的阻挡,大的颗粒灰尘或堆叠的灰尘无法进入吸口,产生垃圾堆叠。为了满足地刷在前推和后拉时具有同样的吸尘效果,我们对后置密封结构就行优化设计。该文对可实现上述功能的设计进行研究,并从成本,新的欧盟能耗法规要去,清洁能力,使用受命等多方面对比,剖析不同设计的优缺点。Current floor brush designs on the market can be categorized into brushless,single-brush,and multi-brush types.Brushless designs are typically used as accessories or with canister vacuum cleaners.The single-brush design,known for its simplicity and low cost,offers effective cleaning on both floors and carpets,making it the mainstream choice.Multi-brush designs,often featuring dual brushes,are represented by products such as Shark’s Duo-cleaning and Dyson’s Double Fluffy^(TM) cleaner head.Regardless of single or multi-brush configurations,most designs effectively handle large debris or stacked dust when pushed forward,but larger debris may stack when pulled back.Toimprove the vacuum seal at the floor brush inlet,a sealing structure—usually composed of soft materials like bristle strips,canvas,or rubber strips—is added to the rear of the inlet with approximately a 1 mmoverlap to increase sealing.However,this design has a drawback:when the floor brush is pulled back,the rear seal can block larger debris or dust stacks,causing themtoaccumulate rather than be suctioned in.Toensure consistent suction efficiency when pushing or pulling the floor brush,we optimized the rear sealing structure.This paper investigates designs that achieve this functionality and com-pares different approaches based on factors such as cost,newEU energy regulations,cleaning effectiveness,and product lifespan,analyzing the strengths and weaknesses of each design.
