往复式电动剃须刀 课题名称： 学生姓名： 李丰 学生学号： 专业班级： 学生成绩： 指导教师： 刘胜荣 课题工作时间： 至 黄山学院教务处制 年 月 日 年 月 日 ? ? 随着社会的不断进步，科技也是日新月异，一些简单的家用电器越来越科学，越来越美观，比如说电动剃须刀。当下的电动剃须刀样式别具一格。电动剃须刀按刀片动作方式分为旋转式和往复式两类。前者结构简单，噪声较小，剃须力适中；后者结构复杂，噪声大，但剃须力大，锋利度高。旋转式电动剃须刀按外形结构又可分为直筒式、弯头式、带电推剪式和双头式几种。前两种结构较简单，后两种较复杂。电动剃须刀按原动机型式可分为直流永磁电动机式、交直流两用串激电动机式和电磁振动式3类。 本次设计的应用价值在当下社会是很大的，设计出与众不同的电动剃须刀样式除了带给商家无限的商机外，也能让人民够赏心悦目。所以，基于电动剃须刀的设计是相当重要的。 三·?课程设计（学年论文）摘要（英文）：  With the constant progress of the society, science and technology is also with each passing day, some simple household appliances is more and more scientific, more and more beautiful, such as electric razor. The current electric razor style having a unique style. Electric shavers in the blade action way is divided into two categories, rotary and reciprocating. The former has simple structure, small noise, shaving force is moderate; The latter complicated structure, large noise, but shaving force is big, high sharpness. Rotary electric razor according to the shape and structure can be divided into the tube, elbow, charged them and double head type. After the first two kinds of structure is simple, two more complex. Electric shavers in prime mover types can be divided into dc permanent magnet motor type, ac/dc series motor and electromagnetic vibration 3 classes. The application value of this design in the present society is very big, design different electric razor style besides companies bring unlimited business opportunities, also can let people enough feast for the eyes. So, based on the design of the electric razor is quite important. 四·成绩评定： 指导教师评语： 指导教师签字： ????????????2年?? 月?? 日 项目 评价 项目 评价 调查论证 ? 工作量、工作态度 ? 实践能力 ? 分析、解决问题能力 ? 质量 ? 创新 ? 得分 ? ………
