摘 要
目前，国内消费市场中“家用食品粉碎机”频频上市，其实对辊破碎机。散发出诱人的魅力，展示着亮丽的市场前景。业内人士认为，“家用食品粉碎机”市场消费面宽，功能新颖独特，http://www.hnfzb.gov.cn/a/zhuanji/fuheshiposuiji/2012/0309/661305.html。它将成为家庭生活的“好伴侣”。圆锥破碎机。本文主要论述了“家用食品粉碎机”的机械结构、外观及控制电路设计。
在这次设计过程中，首先对攀枝花市场进行了调查，收集了大量的资料，然后对粉碎机的外观特征进行了构思，并首次采用了三维建模软件Pro-E对所设计的零部件进行了实体建模，对辊破碎机。突破了二维空间，使其更加直观。在控制电路的设计方面新增了安全触碰压紧开关，使其更具人性化，对人体和电动机更多一层保护。在材料的选择上，大量采用了PC及PVC复合材料，使粉碎机的强度有所提高，并使其重量大大减轻。

ABSTRACT
Now, the domestic consumes the market the inside" the household-use food smashes appliance" appear on market again and again, Send forth an attractive magic power, display the bright market foreground. The industry insider thinks," the household-use food smashes appliance " the market consumes the breadth, the function is novel and special, it will become the " good companion" of the home life. This text discussed primarily" the household-use food smashes appliance " of machine construction, external appearance and control electric circuit design.
In this design process, first has carried on the investigation to the kapok market, has collected the massive materials, then has carried on the idea to the grinder outward appearance characteristic, and used three dimensional modeling software Pro-E to the spare part which designed to carry on the entity modeling for the first time, broke through the two-dimensional space, caused it to be more direct-viewing. Increased in the control circuit design aspect has moved safely contracts the switch, caused it to have the user friendly, were more to the human body and the electric motor a protection. In the material choice, has used PC and the PVC compound materials massively, enable the grinder the intensity to have the enhancement, and causes its weight to reduce greatly.

Keywords The household-use food smashes appliance, machine construction, and external appearance, control electric circuit
