Its main function is to fully mix the gas and air to produce combustible gas, and then ignite it to form a blue flame for cooking. Its structure includes components such as gas nozzles, air holes, mixing chambers and ignition devices. The gas nozzle controls the gas flow, the air holes introduce air to achieve mixing, the mixing chamber ensures sufficient mixing, and the ignition device is used to ignite the mixed gas. The design needs to consider factors such as nozzle diameter, air hole position, mixing chamber volume and ignition device sensitivity.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: an energy-saving gas stove core, including a burner body 1 and an inner air guide pipe 4 integrally formed at the center position of the burner body 1, and a central furnace core 5 is integrally formed at the top of the inner air guide pipe 4, and an air intake control structure is installed at the bottom of the inner air guide pipe 4. When the staff turns on the air intake control structure, natural gas first enters the inner air guide pipe 4, and the natural gas continuously diffuses into the central furnace core 5. An annular outer shell edge 2 is integrally formed at the outer edge of the burner body 1, and an outer hollow combustion disk 3 is integrally formed at the top of the annular outer shell edge 2. An annular sealing disk 6 is fixed on the inner wall of the annular outer shell edge 2, and an air storage chamber 8 is arranged between the annular sealing disk 6 and the outer hollow combustion disk 3. An annular array gas distribution structure 7 for communicating with the air storage chamber 8 is arranged on the outer wall of the inner air guide pipe 4;

[0020] The outer surface of the outer hollow combustion disk 3 and the outer surface of the middle furnace core 5 are respectively provided with an outer gas hole area 301 and a middle gas hole area 501. When the staff uses an igniter to ignite, the natural gas overflowing from the outer gas hole area 301 and the middle gas hole area 501 will be ignited, thereby forming a combustion area at the outer hollow combustion disk 3 and the middle furnace core 5, respectively. The two combustion areas are a central combustion part and an edge combustion part, respectively, thereby forming a stable and uniform flame area, ensuring that the cookware and food are stably heated;

[0021] The air intake control structure is a right-angle air intake pipe 10 installed at the opening position of the bottom end of the inner air guide pipe 4, and a switch valve 11 installed at one end of the right-angle air intake pipe 10 away from the inner air guide pipe 4. The switch valve 11 is connected to the natural gas supply end. When the switch valve 11 is in a normally open state, the natural gas enters the inner air guide pipe 4 through the switch valve 11 and the right-angle air intake pipe 10 to ensure the normal circulation of the natural gas.

[0022] A venturi tube 401 is fixed inside the inner gas pipe 4. The outer diameter of the venturi tube 401 is equal to the inner diameter of the inner gas pipe 4. When natural gas is introduced into the inner gas pipe 4, due to the existence of the venturi tube 401, a local pressure drop will be generated when the gas flows through the venturi tube 401, thereby accelerating the gas flow speed. This acceleration effect can promote the mixing of gas and air, making the mixing more uniform and sufficient.

[0023] The annular array gas distribution structure 7 is composed of a plurality of hollow steel pipes, which are installed at equal intervals on the outer wall of the inner gas pipe 4, and the other ends of the plurality of hollow steel pipes extend to the inside of the outer hollow combustion disk 3. The annular array gas distribution structure 7 is composed of a plurality of hollow steel pipes installed between the inner gas pipe 4 and the gas storage chamber 8, so that the natural gas is diverted through the inner gas pipe 4 and the hollow steel pipes into the gas storage chamber 8;

[0024] Four pot support units 9 are installed at equal intervals at the edge position of the top end of the annular shell edge 2. The pot support unit 9 includes a C-shaped support foot 901 installed on the outer wall of the annular shell edge 2, and an upwardly raised hook portion 902 arranged at the bottom end of the C-shaped support foot 901. The hook portion 902 and the bottom edge of the annular shell edge 2 are mutually engaged. The C-shaped support foot 901 is slidably connected to the bottom opening edge of the annular shell edge 2 through the hook portion 902, which is convenient for users to adjust the position of the C-shaped support foot 901 so that the pot can be stably supported on the filter element.

[0025] When the embodiment of the present application is in use, the staff first connects the air intake end of the air intake control structure to the supply end of the external natural gas. When the staff opens the air intake control structure, the natural gas first enters the inner air guide pipe 4, and the natural gas continuously diffuses into the central furnace core 5. During the diffusion process, the natural gas will form several air flows through the annular array gas distribution structure 7 and enter the gas storage chamber 8 evenly into the outer hollow combustion disk 3. The annular sealing disk 6 makes the inner part of the outer hollow combustion disk 3 form a cavity for the natural gas to enter. When the staff uses the igniter to ignite, the natural gas overflowing from the external gas hole area 301 and the central gas hole area 501 will be ignited, thereby forming a combustion area at the outer hollow combustion disk 3 and the central furnace core 5 respectively. The two combustion areas are The regions are respectively the central combustion part and the edge combustion part, thereby forming a stable and uniform flame area, ensuring that the cookware and food are stably heated. In the furnace core structure, the inner gas guide pipe 4, the central furnace core 5, and the outer hollow combustion disk 3 are adopted. The mixing of gas and air is more uniform and sufficient, and the inner gas guide pipe 4 and the central furnace core 5 guide the gas to the outer hollow combustion disk 3 through the annular array gas distribution structure 7, which ensures the uniform distribution of gas in the gas storage chamber 8, and further forms a more stable and uniform flame environment. Its one-piece structure reduces the use of independent pipelines and reduces the complexity of pipeline layout. At this time, the supply of gas is more concentrated and stable, the flow path is shorter, and the flow resistance is smaller, so that the ignition reaction time of the furnace core is reduced.
