AI Technical Summary
Traditional range hood fan demonstration devices suffer from problems such as unstable smoke generation, easy diffusion, inability to simulate the rising path of real cooking fumes and complex cooking scenarios, resulting in poor visualization effects.
The system uses piezoelectric ceramic atomizing plates and a liquid supply system to stably generate smoke. Combined with the Venturi effect and a multi-ring exhaust pipe assembly, it achieves directional smoke discharge and multi-source oil fume simulation. The airflow direction is adjusted by the air guide plate to form a highly realistic smoke screen.
It significantly improves the directionality and rising speed of smoke, and can simulate the diffusion pattern of multi-source real oil fume with high fidelity, intuitively demonstrating the performance of the range hood, and solving the problems of smoke dispersion and unstable flow of traditional devices.
