[0003] However, the device has the following defects when used: after the fuel is placed in the combustion chamber, the device can ignite the fuel to emit smoke, but the fuel will produce open flames when burning. Under open flames, most of the combustion materials will completely complete the oxidation process under the action of the fire, thus affecting the large-scale production of smoke. For this reason, we propose an experimental smoke generator. Utility Model Content
