AI Technical Summary
The existing barbecue stove lacks smoke treatment structure, which causes smoke generated during the barbecue to enter the atmosphere directly, pollute the environment and affect health.
A smoke self-treatment oven is designed, using a smoke collecting stove and a fan system. After passing the smoke through the filter plate and air filter element, it is reintroduced into the charcoal fire for secondary combustion to reduce the generation of smoke.
By controlling the action of the exhaust fan, the generation of flue gas is reduced and environmental pollution problems are improved. At the same time, the combustion efficiency of carbon fire is improved and the generation of smoke is reduced through secondary combustion.
