便携式野外净水器设计毕设论文.doc

摘要 研究了一种可在野外无固定电源条件下对地表水等水进行快速处理的性价比更高的便携式净水器，对净水流程做了深刻的思考和分析，重新确定了最佳的净水流程，使净水系统的每一级净水更有针对性和可靠性，整个功能设计有很强的环保意识，从动力提供方式的选择，到净水流程中可能出现二次污染的思考，充分体现了绿色设计的概念。它不仅质量轻，方便携带，而且净水速度和净水质量都有保障。内部采用了分筒式的结构设计，由滤芯筒和活塞筒两部分组成，方便拆卸和安装，结构组装设计合理。该净水器不仅功能性很强，外观设计也简洁大方。充分考虑了人机工程学原理。 关键词： 净水器 便携式 净化 Abstract Study a kind of clean machine of water of hold type which can purify the earths surface water etc. under the no power supply condition .the machine has good performance and low price ,so it is welcome to everyone who are want to travel to the nature .Do the deep thinking and analysis to the clean water current distance, re- make sure the best and clean water current distance, make clean system of water of clean water process more pertinence and credibility, the whole function design contain very strong environmental protection consciousness, from the choice of the way of motive provide, go to thinking of the clean water current distance may appear to pollute again, it is full of green design of concept. the quantity is light, it is convenience to take, and the clean speed of water and clean fluid matters quantity has the guarantee. The inner part adopted the structure design of the tube type, constitute from the tube of purifier and the piston tube two parts, it is easy to dismantles to unload and install, the structure construction design reasonable. the clean machine of water not only the function is very strong, external appearance design also simple and direct and generous. Well considered the principle of the person-machine engineering learns. Keywords: the clean machine of water, portable water purifier, clean 目 录 第一章 绪论 1 1.1引言 1 1.2课题背景、目的和意义 3 1.3净水器市场现状和未来 5 1.4本文要完成的内容 8 第二章 净水系统原理设计 9 2.1净水流程设计 9 2.2净水系统动力方案设计 12 2.3净水系统原理设计 12 第三章 净水器结构设计 15 3.1净水器总体结构设计 15 3.2净水器关键零部件设计 15 3.3净水器结构组装设计 27 3.4净水器技术指标的计算 28 第四章 净水器外观设计 29 4.1净水器外观设计手绘草图方案 29 4.2净水器外壳尺寸设计 31 4.3净水器外观效果图 32 4.4产品语义学设计 34 4.5产品细节设计 34 4.6净水器外观设计说明 34 第五章 结论与展望 36 5.1产品综合性能论述 36 5.2产品设计的优缺点评析 38 5.3展
