Description

Technical Field

[0001] The utility model relates to the field of stove cores, in particular to a welding-free combined heating stove core. Background Art

[0002] The stove core is a key component of the stove burning wood and coal. Its excellent fire-gathering ability will directly affect the length of time the pot is heated. When heating the same pot, the stove core with better fire-gathering can bring about a high flame and a strong flame impact, which will greatly save fuel and achieve a rapid heating effect. Most existing stove cores have a larger upper opening and a smaller lower opening. When the fuel is burning, the flame heats the pot at the stove mouth slowly and for a long time, which easily causes heat loss, which is what people often call scattered fire and no pot support, greatly reducing the heating efficiency. At the same time, the existing stove core needs to be welded to the outer barrel during installation. Welding is generally manual, time-consuming and labor-intensive, and easily causes harm to workers. The quality of welding cannot be guaranteed. Once the welding is not firm, it is easy to fall off during use, thereby injuring the user's feet, posing a safety risk.

[0003] Therefore, there is an urgent need for a welding-free combined heating stove core that can solve the problems of the existing stove core that when heating cookware, the flame easily overflows the stove core, causing heat loss, flame dispersion, low heating efficiency, and assembly relies on welding, resulting in poor product quality.
