Abstract

To comprehensively improve the drying efficiency and functional experience of pet drying boxes, the work aims to design a "dual lung model" intelligent pet drying box with "bidirectional circulation and multi-faceted circulation". The fluid mechanics and design principles of the "dual lung model" air duct were proposed, and the industry-leading SolidWorks Simulation finite element analysis tool was used for cavity modeling and air circulation system simulating experiments to underpin the design process. Based on the air duct test results, the basic configuration of the "dual lung model" pet drying box air duct design was derived. According to the results of the cavity test and intelligent design methods, the product appearance and functional structure design were carried out. The finite element analysis based on SolidWorks Simulation experiments showed that the "double lung model" with a 17.5° convex cavity with bottom air inlet of "three in and two out" could maximize the utilization of airflow and improve drying efficiency when used in the air duct design of pet drying boxes. Functional analysis shows that the "dual lung model" air duct design improves the airflow and air circulation inside the chamber, maintaining good drying efficiency even with reduced airflow. The reduction in airflow helps to enhance pet adaptability and reduce noise interference. The drying effect test and user experience evaluation have verified the comprehensive improvement of the product's functional experience by the "dual lung model" air duct design.
