家用食品粉碎机的设计讲解.doc

毕业论文题目 摘 要 目前，国内消费市场中“家用食品粉碎机”频频上市，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，它将成为家庭生活的“好伴侣”。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，首先收集了大量的资料，然后对粉碎机的外观特征进行了构思。家用食品粉碎机主要由机座、刀具、料杯几部分组成。刀具由机座内的电机直接带动，既节省了空间，又提高了效率。料杯杯体与机座容易拆卸便于存放，刀具可以方便的交替使用，既避免了卫生死角，又能方便快捷的清洗。在控制电路的设计方面采用了安全触碰压紧开关，使其更具人性化，对人体更多一层保护。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。家用食品粉碎机可以调制果汁、奶昔、豆浆，研磨粉碎食物，绞肉等，功能强大，用途广泛！ 关键词：家用食品粉碎机；机械结构；外观；控制电路 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
