手持式车用多功能吸尘器结构设计
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。

Abstract
With the development of science and technology, improvement of living standards, More and more family have car. Carvacuum cleaner market, its potential is extremely alarming. According to the survey, although up to 95% of the domestic user's intention to buy car cleaners, so far, due to the traditionalvacuum cleaner all the technical and design issues, the purchase rate of the domestic car cleaners is not high. The huge market potential here, this projectwill design a handheld carwith multi-functionvacuum cleaner.
This subject under the three-dimensional digital modeling idea, through the use of SolidWorks software for computer-aided design, sketch the design process. Coarse mode, and then calculated the data obtained from a number of three-dimensional modeling, the final model for interference checking.simulate assembly and fluid analysis and processing, concluded that the overall structure of the model ofvacuum cleaner. Industrial cyclone separator dustvacuum cleaner dust part of the overall design of the article.Related to the structure design, 3D modeling, aerodynamics, and other content.The core of this topic include: the design of the dust separation devices, cyclone size design, thewind impeller structure design.
Dust separation unit part, by two cyclone: the upstream cyclone, downstream cyclone. Upstream cyclone separation of larger particles of dust and impurities. The gas passes through the middle of the mesh into the downstream cyclone. The downstream cyclone cyclone in parallel by six small, through the use of parallel technology, can greatly improve the separation efficiency. The appearance of the size of the downstream cyclone inclination design details.
Part of the fan system design, filter, air impeller, motor, exhaust hood and other components, the mainwind impeller blade size design calculations, andwind impeller static analysis and fluid analysis obtainedvarious parameters, then its blade angle parameters to modify it to maximizeventilation efficiency.
The article ejection switch on the dust cover, filter cover and spiral air intake parts to make a brief design, described the structure of difficultywith the design process, the size calculation is omitted.
Keywords：Multi-functionvacuum cleaner; cyclone separation technology; structural design; fluid analysis
