Description

Technical Field

[0001] The utility model relates to a novel furnace core assembly. Background Art

[0002] Combustion furnaces are widely used in daily life such as cooking. Generally, they include a furnace chamber, a furnace core, an atomizing nozzle, and an igniter. For example, in the Chinese utility model patent with the authorization announcement number CN218846119U and the name of "A Combustion Furnace for Preventing the Atomizing Nozzle from Caking", the inventor disclosed a combustion furnace. The furnace core is located in the furnace chamber. The furnace core has a first furnace section and a second furnace section arranged successively from top to bottom. The lower end of the second furnace section is externally sleeved with an isolation cover with an open top and a closed bottom. The center position of the upper bottom of the isolation cover is provided with an installation hole, and a plurality of air inlet holes are arranged along the periphery of the installation hole and surround the central hole. Each air inlet hole of the above patent can enable the air in the air supply pipeline to enter the isolation cover, and the air entering the isolation cover can surround the oil outlet end of the atomizing nozzle, so as to continuously cool the oil outlet end of the atomizing nozzle in the isolation cover and achieve certain effects. However, when such a furnace core is in use, the air volume fed into the furnace core for combustion support is not stable enough, resulting in unstable flames, and the combustion efficiency of the entire furnace core needs to be further improved.

[0003] Based on the above problems, the applicant has studied the above problems and developed this case. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel furnace core assembly with a simple structure and more stable combustion.

When the incoming air is sent upward from the intermediate chamber to the upper part of the furnace core body, it is secondarily dispersed through the second air inlet hole, so that the incoming air is evenly dispersed into the inner cavity of the furnace core body, enabling the fuel fed into the furnace core body to burn more evenly, making the flame more stable, improving the combustion efficiency, and its overall structure is simple and practical. Further, the fire dividing piece of the present utility model changes the traditional fire dividing fin structure, has a simple structure and is easy to process. Through the fire guiding holes, the flame can be dispersed outward, ensuring the combustion width of the flame. The annular flange can guide the flame, preventing the flame from concentrating at the center of the furnace core body, avoiding excessive concentration of the firepower at the bottom of the pot, and facilitating the taking and placing of the fire dividing piece for daily taking and placing and maintenance of the furnace core. Further, the present utility model is provided with a first through hole and a second through hole on both sides of the flame concentrating ring. The air supply through the first through hole plays a role in assisting combustion, and the air supply through the second through hole can cool the flame concentrating ring correspondingly, preventing the flame concentrating ring from being damaged due to being in a high-temperature condition for a long time, thereby improving the service life of the flame concentrating ring.
