1、摘 要随着科技的发展,生活水平的提高,拥有汽车的家庭越来越多。车载吸尘器市场,它的潜力极为惊人。但据调查,虽然国内高达95%的用户有购买车载吸尘器的意向,可迄今为止,由于传统的吸尘器的种种技术和设计问题,国内车载吸尘器的购买率却不高。针对该市场的巨大潜力,于此,本课题将设计出一个手持式车用多功能吸尘器。本课题根据三维数字化建模思想,通过采用SolidWorks软件进行计算机辅助设计,设计过程中经过草绘、粗模、再计算,将所得的数据进行了多次三维建模,最后利用模型进行干涉检查、模拟装配和流体分析等处理,最终得出吸尘器的整体结构模型。文章中采用工业旋风分离除尘技术对吸尘器集尘部分进行整体设计。其涉及
2、到结构设计、三维造型、空气动力学等内容。本课题设计的核心部分包括:集尘分离装置的设计、旋风分离器相关尺寸设计、风叶轮结构设计。集尘分离装置部分,其由两组旋风分离器构成:上游旋风分离器、下游旋风分离器。上游旋风分离器分离颗粒较大的灰尘、杂质。气体通过中间的网孔进入下游旋风分离器。下游旋风分离器由6个小旋风分离器并联构成,通过采用并联技术,可大大提高分离效率。对下游小旋风分离器的外观尺寸、倾角设计进行了的详细介绍。 风机系统设计部分,由过滤网,风叶轮,电机,排气罩等组成,主要介绍风叶轮叶片尺寸设计计算,并对风叶轮进行静力分析和流体分析,得出各种参数,再对其叶片角度参数进行修改,使其抽风效率达到最大
3、化。文章中对集尘筒盖弹射开关、过滤网罩和螺旋进风口部件做出了简要的设计,阐述了其结构难点与设计过程,其相关尺寸计算省略。关键词:多功能吸尘器;旋风分离技术;结构设计;流体分析AbstractWith the development of science and technology, improvement of living standards, More and more family have car.
