Abstract
Nowadays, a small household juicer is an important and useful tool in the kitchen. Therefore, increasing its lifespan and improving its performance are crucial. A 3-D modeling of the small household fruits and vegetables juicer by using Creo 7.0 software was created in the current study. The screw, knife net and transmission shaft of a juicer were analyzed by using ANSYS 23 R1. The analysis yielded a maximum von Mises stress of 7.9343 MPa on the transmission shaft and 5.6102 MPa on the juicer screw. These findings indicate that the design effectively meets the required specifications, ensuring both functionality and durability. The validation process was developed by comparing the maximum stress values obtained from the Finite Element Analysis (FEA) with the theoretical stress values calculated manually to confirm the accuracy and reliability of the simulation model. In this paper, a child-lock mechanism was added to the juicer structure to enhance safety for children. The structure ensures that the machine will stop automatically if the upper cover is opened. This innovation adds significant value to the juicer, helping it stand out in a competitive market.
