[0002] Stoves (or fireboxes) are used for cooking or heating and are widely used indoors or outdoors in rural areas. Various structural types of stoves have emerged on the market to cater to different usage scenarios. For wood-burning stoves used in rural areas or outdoors, heat is mainly generated by burning coal, wood, branches, straw, etc. However, currently available stoves have an open structure, allowing fuel such as coal to burn freely without adjusting the heat output. When a lower heat output is needed, more fuel is burned, resulting in significant waste. Summary of the Invention
