摘    要
目前，國(guó)內(nèi)消費(fèi)市場(chǎng)中“家用食品粉碎機(jī)”頻頻上市，散發(fā)出誘人的魅力，展示著亮麗的市場(chǎng)前景。業(yè)內(nèi)人士認(rèn)為，“家用食品粉碎機(jī)”市場(chǎng)消費(fèi)面寬，功能新穎獨(dú)特，它將成為家庭生活的“好伴侶”。本文主要論述了“家用食品粉碎機(jī)”的機(jī)械結(jié)構(gòu)、外觀及控制電路設(shè)計(jì)。
在這次設(shè)計(jì)過程中，首先收集了大量的資料，然后對(duì)粉碎機(jī)的外觀特征進(jìn)行了構(gòu)思。家用食品粉碎機(jī)主要由機(jī)座、刀具、料杯幾部分組成。刀具由機(jī)座內(nèi)的電機(jī)直接帶動(dòng)，既節(jié)省了空間，又提高了效率。料杯杯體與機(jī)座容易拆卸便于存放，刀具可以方便的交替使用，既避免了衛(wèi)生死角，又能方便快捷的清洗。在控制電路的設(shè)計(jì)方面采用了安全觸碰壓緊開關(guān)，使其更具人性化，對(duì)人體更多一層保護(hù)。在材料的選擇上，大量采用了PC及PVC復(fù)合材料，使粉碎機(jī)的強(qiáng)度有所提高，并使其重量大大減輕。家用食品粉碎機(jī)可以調(diào)制果汁、奶昔、豆?jié){，研磨粉碎食物，絞肉等，功能強(qiáng)大，用途廣泛！

ABSTRACT
Now, the domestic consumes the market 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 I collected the massive materials, then carried on the idea of the outward appearance characteristic of the grinder. The homehold-use food smashes appliance is mainly composed by the base, the cutting tool,and the material cup . The cutting tool is impetused by the moter in the base directly, both saved the space, and enhanced the efficiency. The material cup and the base can be easily disassembled for depositing conve- niencely, the cutting tools may be used in turn, both has avoided the hygienic dead angle, and can be cleaned quickly.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 materials, I used PC and the PVC compound materials massively, enable the grinder the intensity to have the enhancement, and to reduce its weight greatly. The homehold-use food smashes appliance may modulate the fruit juice, the milk shake, the soybean milk, attrition smashing food, twists the meat, the function is formidable, versatility!

Key words: Household-use food smashes appliance；Machine construction；External appearance；Control electric circuit
