Research On The Main Mechanism Of Home Care Shampoo

Washing hair is one of the most important home care in our everyday life, it’s done by hand at present, but for the elderly,it is so difficult to completed by themselves. In recent years, although some research has been done on shampoo machine’s main body, the existing shampoo machine still can’t satisfy our requirements, due to the complexity of mechanical movement and the head’s irregular shape. So a new mechanism is necessary to be designed for home care shampoos machine, and it can replace the traditional hair shampoo and can complete the washing process. The main research contents of this paper are as follows:Firstly, the characteristic equations of motion are derived from the analysis of the process of manual hair shampoo. The required space of the mechanism was got through the analysis of the size of elder’s head. The suitable posture for the elder is selected by the analysis of the characteristics of the existing washing pose. Selecting the body of the washing machine based on the required space, motion equation characteristics and the selected washing posture.Secondly, according to the characters of shampoo movement equation, type synthesized to the main body’s parallel mechanism and series mechanism by used the synthesis of the branch So Cs and the topological structure synthesis of the serial mechanism. Optimized the synthesized mechanism based on the topology characteristics of spatial mechanism and the requirements of washing. The optima’s degree of freedom is also verified.Thirdly, the kinematics analysis of the main body mechanism was carried on, including positive solution and inverse solution of the position, the singularity and the workspace. The function relationship of the main body mechanism’s input and output is got through the analysis of the washing machine’s main body position; laid the foundation for the analysis of singularity. Verified the working space satisfied the required washing space by solving the main body’s working space.Finally, modeling and assembly the main body mechanism by using UG; the kinematics simulation analysis of the main body is carried on by using the ADAMS. The simulation results turned out that the main mechanism of the washing machine can satisfy the requirements of washing head.
