This work is to investigate the impact of different structural air path and air chamber designs on the performance of odor recognition devices, as well as to summarize the key design parameters to provide reference for the practical application of odor recognition products in the home environment. Based on the modular design technique, six different air path structures were designed for e-nose home applications, followed by e-nose response test experiments to compare the performance differences of the six structures, and then the deployment mode and usage of e-nose in different home application scenarios were discussed based on the experimental results, as well as how the experimental results can be applied in the actual product design process. The results reveal that differing air chamber structures have a substantial impact on the response performance of e-nose, which has implications for the design of air paths for odor collection applications in home scenarios, potentially improving odor recognition capabilities, empowering home function and service innovation, and improving user experience.
