[0002] With the improvement of people's living standards and the pursuit of leisure life, more and more people like to go to the wild for outdoor activities and self-driving tours during holidays. Stoves are often used in outdoor activities or self-driving tours. Since there is a lot of firewood outdoors, a variety of outdoor wood stoves have also been popular. When using a traditional wood stove, ashes will be produced after the firewood is burned, the ashes produced are placed together with the burning wood. After use, it is necessary to remove the unburned wood, then turn the furnace body over, and pour out the ashes from the opening of the furnace body. Because the furnace body is generally heavy, this method is extremely time-consuming and laborious, and the furnace mouth and the inner wall of the furnace will be stained with ashes, which is easy to raise dust during subsequent use, affecting user experience and health.
[0003] For example, a multifunctional outdoor wood-fired stove disclosed in a Chinese utility model patent (publication number: CN216293821U) includes a full-area grilling plate, a grilling rack, a half-area grilling plate and a stove body. A first limit plate is provided on the inner wall of the front and rear panels of the stove body, an air curtain plate is provided above the front and rear panels of the stove body, a top air inlet is provided on the air curtain plate, a charcoal fire grid is provided in the stove body, an ash receiving drawer is provided below the charcoal fire grid to close the opening below the stove body, more than one side air inlet is provided on the side panel of the stove body, an annular through groove is provided below the side air inlet, and an air inlet adjustment component is inserted in the annular through groove. Its structural setting is simple and reasonable, and its functions are diverse, which can meet the different usage needs of users. However, since it has only one stove door, adding fuel and cleaning the burning ashes in the furnace are all done through the stove door. When cleaning the burning ashes, the stove body needs to be turned over and the ashes need to be poured out from the opening of the stove body, which is not only inconvenient to clean the ashes, but also not conducive to the subsequent cleaning of the furnace.
