[0059] The inner fire cover 310 is provided with an inner fire cover fire hole 311 and an inner fire cover oxygen supply hole 312, and the inner fire cover oxygen supply hole 312 is arranged adjacent to the inner fire cover fire hole 311. The outer fire cover 320 is provided with an outer fire cover fire hole 321 and an outer fire cover oxygen supply hole 322, and the outer fire cover oxygen supply hole 322 is arranged adjacent to the outer fire cover fire hole 321. The inner fire cover oxygen supply hole 312 and the outer fire cover oxygen supply hole 322 are both connected to the secondary air channel 400.

[0060] Specific combination Figures 1 to 6 As shown, both the inner fire cover 310 and the outer fire cover 320 are annular. The inner fire cover 310 is located inside the outer fire cover 320 and is arranged concentrically with the outer fire cover 320. The burner head 100 is connected to the inner fire cover 310 and the outer fire cover 320 respectively through the gas distributor 200. The inner fire cover oxygen supply hole 312 is located adjacent to the inner fire cover fire hole 311, and the outer fire cover oxygen supply hole 322 is located adjacent to the outer fire cover fire hole 321. In addition, the secondary air channel 400 is connected to the inner fire cover oxygen supply hole 312 and the outer fire cover oxygen supply hole 322. When using a gas stove, the burner head 100 passes the gas to the inner fire cover 310 and the outer fire cover 320 through the gas distributor 200, and the gas is burned through the inner fire cover fire hole 311 and the outer fire cover fire hole 321; because the inner fire cover 310 is provided with an inner fire cover oxygen supply hole 312 corresponding to the inner fire cover fire hole 311, and the outer fire cover 320 is provided with an outer fire cover oxygen supply hole 322 corresponding to the outer fire cover fire hole 321, and the inner fire cover oxygen supply hole 312 and the outer fire cover oxygen supply hole 322 are both connected to the secondary air channel 400; when the gas passes through the inner fire cover When the fire hole 311 and the outer fire cover fire hole 321 are burning, the inner fire cover oxygen supply hole 312 supplies oxygen to the root of the flame generated by the corresponding inner fire cover fire hole 311, and the outer fire cover oxygen supply hole 322 supplies oxygen to the root of the flame generated by the corresponding outer fire cover fire hole 321. The entire secondary air supply process is targeted to ensure that each inner fire cover fire hole 311 and outer fire cover fire hole 321 can receive secondary air during the gas combustion process, ensuring that the gas is fully burned while achieving an appropriate amount of secondary air supply.

[0061] In the optional technical solution of this embodiment, the inner fire cover oxygen supply hole 312, the inner fire cover fire hole 311, the outer fire cover oxygen supply hole 322 and the outer fire cover fire hole 321 are all provided with a plurality;

[0062] Multiple inner fire cover oxygen supply holes 312 and multiple inner fire cover fire holes 311 are evenly spaced along the circumference and arranged at one end of the inner fire cover 310 away from the gas distribution seat 200, and an inner fire cover oxygen supply hole 312 is arranged between two adjacent inner fire cover fire holes 311;

[0063] And / or, multiple outer fire cover oxygen supply holes 322 and multiple outer fire cover fire holes 321 are evenly spaced along the circumference at one end of the outer fire cover 320 away from the gas distribution seat 200, and an outer fire cover oxygen supply hole 322 is provided between two adjacent outer fire cover fire holes 321.

Since an inner fire cover oxygen supply hole 312 is provided between two adjacent inner fire cover fire holes 311, and an outer fire cover oxygen supply hole 322 is provided between two adjacent outer fire cover fire holes 321, each inner fire cover oxygen supply hole 312 can provide secondary air supply to two adjacent inner fire cover fire holes 311, and each inner fire cover fire hole 311 can receive secondary air supply from both sides, and each outer fire cover oxygen supply hole 322 can provide secondary air supply to two adjacent outer fire cover fire holes 321, and each outer fire cover fire hole 321 can receive secondary air supply from both sides. When the gas burns through the outer fire cover fire holes 321 and the inner fire cover fire holes 311, the gas can be burned more fully, further improving the utilization rate of the gas combustion. In addition, since the multiple inner fire cover oxygen supply holes 312 and the multiple inner fire cover fire holes 311 are evenly spaced along the circumferential direction on the inner fire cover 310, and the multiple outer fire cover oxygen supply holes 322 and the multiple outer fire cover fire holes 321 are evenly spaced on the outer fire cover 320; in the process of combustion of gas through the outer fire cover fire holes 321 and the inner fire cover fire holes 311, the difference in fire power at various locations of the inner fire cover 310 and the outer fire cover 320 is reduced, thereby improving the stability of gas combustion and enhancing the user experience.

[0065] In an optional technical solution of this embodiment, a first corrugated portion 3101 is provided at one end of the inner fire cover 310 away from the gas distributor seat 200, and a second corrugated portion 3201 is provided at one end of the outer fire cover 320 away from the gas distributor seat 200;

[0066] A plurality of inner fire cover fire holes 311 are provided on the inner side wall of the first corrugated portion 3101 , and the inner fire cover oxygen supply holes 312 extend from the outer side of the first corrugated portion 3101 to the inner side of the inner fire cover 310 , and the plurality of inner fire cover fire holes 311 are provided near the end of the first corrugated portion 3101 ;

[0067] Multiple external fire cover fire holes 321 are arranged on the inner wall of the second corrugated part 3201, and the external fire cover oxygen supply hole 322 passes through the outside of the second corrugated part 3201 to the inside of the external fire cover 320, and multiple external fire cover fire holes 321 are arranged near the end of the second corrugated part 3201.

[0068] Specific combination Figure 4 and Figure 5 As shown, the inner wall of the first corrugated portion 3101 gradually increases in diameter in the direction away from the gas separation seat 200, and the outer wall gradually decreases in diameter in the direction away from the gas separation seat 200. A plurality of inner fire cover fire holes 311 are evenly spaced and arranged on the inner wall of the first corrugated portion 3101. Figure 4As shown, the inner fire cover oxygen supply hole 312 passes through the inner side wall of the first corrugated part 3101, and multiple inner fire cover fire holes 311 are arranged near the upper edge of the first corrugated part 3101. The inner side wall of the second corrugated part 3201 gradually increases in diameter in the direction away from the gas separation seat 200, and the outer side wall gradually decreases in diameter in the direction away from the gas separation seat 200. Multiple outer fire cover fire holes 321 are evenly spaced and arranged on the inner side wall of the second corrugated part 3201, as shown in FIG. Figure 5 As shown, the outer fire cover oxygen supply hole 322 passes through the inner wall of the second corrugated portion 3201 , and multiple outer fire cover fire holes 321 are arranged near the upper edge of the second corrugated portion 3201 . Since the diameter of the inner wall of the first corrugated portion 3101 gradually increases in the direction away from the gas distributor seat 200, multiple inner fire cover fire holes 311 are evenly spaced on the inner wall of the first corrugated portion 3101. When the gas burns from the multiple inner fire cover fire holes 311, the flames are concentrated in the middle, thereby improving the heating effect. The multiple inner fire cover fire holes 311 are arranged close to the upper edge of the first corrugated portion 3101. When in use, secondary air passes from the outside of the first corrugated portion 3101 to the corresponding inner fire cover fire holes 311 on the inside of the first corrugated portion 3101 through the inner fire cover oxygen supply holes 312, thereby replenishing oxygen for the flame of the inner fire cover fire holes 311. Since air is light in weight and will float up, the inner fire cover oxygen supply holes 312 are arranged above the inner fire cover fire holes 311, thereby further improving the secondary air supply effect. Since the diameter of the inner wall of the second corrugated portion 3201 gradually increases in the direction away from the gas distributor seat 200, multiple outer fire cover fire holes 321 are evenly spaced on the inner wall of the first corrugated portion 3101. When the gas burns from the outer fire cover fire holes 321, the flames are concentrated in the middle, thereby improving the heating effect; multiple outer fire cover fire holes 321 are arranged near the upper edge of the second corrugated portion 3201. When in use, secondary air passes from the outside of the second corrugated portion 3201 to the corresponding outer fire cover fire holes 321 on the inside of the second corrugated portion 3201 through the outer fire cover oxygen supply holes 322, thereby replenishing oxygen for the flames of the outer fire cover fire holes 321. Since air is light in weight and will float up, the outer fire cover oxygen supply holes 322 are arranged above the outer fire cover fire holes 321, thereby further improving the secondary air supply effect, promoting more complete combustion of the gas, and improving the gas utilization rate.

[0069] In an optional technical solution of this embodiment, the inner fire cover 310 is provided with an inner fire cover air cavity 313, and the plurality of inner fire cover fire holes 311 are all connected to the inner fire cover air cavity 313;

[0070] The outer fire cover 320 is provided with an outer fire cover air cavity 323 , and the plurality of outer fire cover fire holes 321 are all communicated with the outer fire cover air cavity 323 .

[0071] Specific combination Figure 4 and Figure 5As shown, the inner fire cover air cavity 313 is arranged along the circumference of the inner fire cover 310 at the end of the inner fire cover 310 away from the first corrugated portion 3101, and the outer fire cover air cavity 323 is arranged along the circumference of the outer fire cover 320 at the end of the outer fire cover 320 away from the second corrugated portion 3201. When using gas, the gas reaches the inner fire cover 310 and the outer fire cover 320 respectively through the gas distribution seat 200, and is stored in the inner fire cover air cavity 313 and the outer fire cover air cavity 323 respectively; multiple inner fire cover fire holes 311 are connected to the inner fire cover air cavity 313, and the gas diffuses from the inner fire cover air cavity 313 to the multiple inner fire cover fire holes 311, and multiple outer fire cover fire holes 321 are connected to the outer fire cover air cavity 323, and the gas diffuses from the outer fire cover air cavity 323 to the multiple outer fire cover fire holes 321, ensuring that the gas reaches the multiple outer fire cover fire holes 321 and the multiple inner fire cover fire holes 311 as evenly as possible, ensuring the stability of the gas combustion, and also improving the stability and safety during ignition.

[0072] In an optional technical solution of this embodiment, an inner fire cover flame stabilizing groove 314 is provided on the inner side wall of the first corrugated portion 3101. The inner fire cover flame stabilizing groove 314 is provided on one side of the inner fire cover oxygen supply hole 312 away from the multiple inner fire cover fire holes 311 and extends circumferentially along the inner fire cover 310.

Because the multiple inner fire cover flame stabilizing holes communicating with the inner fire cover air cavity 313 are provided on the first corrugated portion 3101, and the multiple outer fire cover flame stabilizing holes communicating with the outer fire cover air cavity 323 are provided on the second corrugated portion 3201. During ignition, the gas burns simultaneously from multiple inner fire cover flame stabilizing holes, multiple outer fire cover flame stabilizing holes, multiple outer fire cover fire holes 321, and multiple inner fire cover fire holes 311, thereby improving the stability of the gas during combustion. Moreover, since the multiple inner fire cover flame stabilizing holes are arranged in the inner fire cover flame stabilizing groove 314, and the multiple outer fire cover flame stabilizing holes are arranged in the outer fire cover flame stabilizing groove 324, when the gas burns through the multiple inner fire cover flame stabilizing holes and the multiple outer fire cover flame stabilizing holes, the inner fire cover flame stabilizing groove 314 and the outer fire cover flame stabilizing groove 324 further improve the stability of the gas during combustion, thereby reducing the probability of flying fire and uneven firepower.

[0076] In an optional technical solution of this embodiment, the aperture of the inner fire cover flame stabilizing hole is smaller than the aperture of the inner fire cover fire hole 311 , and the aperture of the outer fire cover flame stabilizing hole is smaller than the aperture of the outer fire cover fire hole 321 .

[0077] Specific combination Figure 4 and Figure 5 As shown, the flame stabilizing holes of the inner fire cover and the flame stabilizing holes of the outer fire cover play the role of stabilizing the flame and avoiding flying fire. The aperture of the inner fire cover fire hole 311 is larger than the aperture of the inner fire cover flame stabilizing hole, and the aperture of the outer fire cover fire hole 321 is larger than the aperture of the outer fire cover flame stabilizing hole, ensuring that most of the gas is burned through the inner fire cover fire hole 311 and the outer fire cover fire hole 321 when burning, thereby ensuring the use effect of the burner.

[0078] In an optional technical solution of this embodiment, the depth direction of the inner fire cover flame stabilizing groove 314 and the depth direction of the outer fire cover flame stabilizing groove 324 are both set at an angle to the axis of the inner fire cover 310.

[0079] Specific combination Figure 4 and Figure 5 As shown, the inner fire cover flame stabilizing groove 314 is set at an angle to the inner side surface of the first corrugated part 3101, and the outer fire cover flame stabilizing groove 324 is set at an angle to the inner side surface of the second corrugated part 3201. When the gas burns through the inner fire cover flame stabilizing holes and the outer fire cover flame stabilizing holes, the flames gather toward the center, which not only has the effect of stabilizing the flame, but also has the effect of gathering the fire, further improving the use effect of the burner.

[0080] In an optional technical solution of this embodiment, the axes of the multiple inner fire cover fire holes 311 and the axes of the multiple outer fire cover fire holes 321 are both tilted around the axis of the inner fire cover 310, and the tilt directions are opposite.

[0081] Specific combination Figures 4 to 6As shown, when looking down at the inner fire cover 310 and the outer fire cover 320 in the installed state, the axes of the multiple inner fire cover fire holes 311 are tilted in the clockwise or counterclockwise direction, and the axes of the multiple outer fire cover fire holes 321 are tilted in the counterclockwise or clockwise direction accordingly. Figure 6 As shown, the axes of the multiple inner fire cover fire holes 311 are tilted counterclockwise, while the axes of the multiple outer fire cover fire holes 321 are tilted clockwise. Because the axes of the multiple inner fire cover fire holes 311 and the axes of the multiple outer fire cover fire holes 321 are both tilted about the axis of the inner fire cover 310, and the tilt directions are opposite, the flames generated by the combustion of gas through the multiple inner fire cover fire holes 311 and the outer fire cover fire holes 321 burn in opposite directions, thereby converging the heat from the combustion of the gas, increasing the flame temperature and further improving combustion efficiency.

[0082] In the optional technical solution of this embodiment, the gas distribution seat 200 includes a gas distribution component 210 and a plurality of legs 220, and the inner fire cover 310 and the outer fire cover 320 are connected to the burner head 100 through the gas distribution component 210;

[0083] A plurality of legs 220 are installed at intervals on one end of the gas distribution assembly 210 close to the furnace head 100 .

[0084] Specific combination Figures 1 to 3 and Figure 7 As shown, a plurality of legs 220 are evenly spaced and mounted on one end of the gas distribution assembly 210 near the burner head 100, forming a secondary air passage 400 between the gas distribution assembly 210 and the burner head 100. The secondary air passage 400 communicates with the area between the inner fire cover 310 and the outer fire cover 320, and the inner fire cover 310 and the outer fire cover 320 are connected to the burner head 100 through the gas distribution assembly 210. When the gas stove is in use, gas flows from the burner head 100 through the gas distribution assembly 210 to the inner fire cover 310 and the outer fire cover 320, respectively. Gas is discharged and burned through the multiple inner fire cover fire holes 311 and the outer fire cover fire holes 321. The secondary air passage 400 provides air supply for combustion, ensuring more complete combustion of the gas, reducing the emission of waste gases such as carbon monoxide, and thus saving energy and reducing emissions.

[0085] In the optional technical solution of this embodiment, the gas distribution assembly 210 includes an inner fire cover gas distribution member 211 and an outer fire cover gas distribution member 212. The inner fire cover gas distribution member 211 is arranged inside the outer fire cover gas distribution member 212 and is connected to each other;

[0086] The inner fire cover gas distributor 211 is communicated with the inner fire cover 310 and the burner head 100 respectively, and the outer fire cover gas distributor 212 is communicated with the outer fire cover 320 and the burner head 100 respectively.

[0087] Specific combination Figure 7As shown, the inner fire cover air divider 211 is arranged corresponding to the air outlet of the inner fire cover 310 and the burner head 100, and the inner fire cover 310 and the burner head 100 are connected through the inner fire cover air divider 211; the outer fire cover air divider 212 is arranged corresponding to the air outlet of the outer fire cover 320 and the burner head 100, and the outer fire cover 320 and the burner head 100 are connected through the outer fire cover air divider 212; the inner fire cover air divider 211 and the outer fire cover air divider 212 are fixedly connected, and the inner fire cover air divider 211 is arranged on the inner side of the outer fire cover air divider 212. After the gas comes out from the gas outlet of the burner 100, it reaches the inner fire cover 310 through the inner fire cover gas distributor 211, and reaches the outer fire cover 320 through the outer fire cover gas distributor 212. The gas accumulates in the inner fire cover gas distributor 211 and the outer fire cover gas distributor 212 to ensure the stability of the gas after combustion; at the same time, it avoids the mixing of the gases discharged to the inner fire cover 310 and the outer fire cover 320, which causes uneven distribution of fire power discharged to the inner fire cover 310 and the outer fire cover 320, further improving the use effect of the gas stove.

[0088] In an optional technical solution of this embodiment, the burner head 100 is provided with a first air inlet 110, a second air inlet 120, a plurality of first air outlet channels 130, and a plurality of second air outlet channels 140. The plurality of first air outlet channels 130 and the plurality of second air outlet channels 140 are both provided at one end of the burner head 100 close to the gas distribution assembly 210 and are spaced apart along the circumference of the burner head 100, and the first air outlet channels 130 are located within the area enclosed by the plurality of second air outlet channels 140.

[0089] The plurality of first air outlet channels 130 are respectively communicated with the first air inlet 110 and the inner fire cover air distributor 211 , and the plurality of second air outlet channels 140 are respectively communicated with the second air inlet 120 and the outer fire cover air distributor 212 .

[0090] Specific combination Figure 7 and Figure 8 As shown, in this embodiment, two first gas outlet channels 130 and four second gas outlet channels 140 are provided. The two first gas outlet channels 130 are located in the middle of one end of the burner head 100 near the gas distributor assembly 210. The four second gas outlet channels 140 are evenly spaced along the circumference of the burner head 100 at one end of the burner head 100 near the gas distributor assembly 210. The first gas outlet channels 130 are located within the area surrounded by the multiple second gas outlet channels 140. The two first gas outlet channels 130 are both connected to the first air inlet 110 and the inner fire cover gas distributor 211, and the four second gas outlet channels 140 are both connected to the second air inlet 120 and the outer fire cover gas distributor 212.

[0091] During use of the gas stove, a portion of the gas enters the burner head 100 through the first air inlet 110, is discharged from the two first air outlet channels 130, and then enters the inner fire cover 310 through the inner fire cover gas distributor 211. Another portion of the gas enters the burner head 100 through the second air inlet 120, is discharged from the four second air outlet channels 140, and then enters the outer fire cover 320 through the outer fire cover gas distributor 212. The two gas routes reaching the inner fire cover 310 and the outer fire cover 320 are completely independent, preventing the gases entering the inner fire cover 310 and the outer fire cover 320 from mixing with each other, ensuring that the inner fire cover 310 and the outer fire cover 320 will not have uneven fire distribution during use, further improving the performance of the gas stove. The two first gas outlet channels 130 and the four second gas outlet channels 140 are evenly spaced at one end of the burner 100 close to the gas distribution assembly 210, further improving the synchronization of the gas reaching various locations of the inner fire cover 310 and the outer fire cover 320, and further improving the stability of the gas combustion process.

[0092] In addition, the number of the first gas outlet channels 130 and the second gas outlet channels 140 can be appropriately increased or decreased according to actual needs, so as to achieve the technical purpose of completely independent two-way gas flow reaching the inner fire cover 310 and the outer fire cover 320.

[0093] In an optional technical solution of this embodiment, the burner 100 further includes a first air mixing chamber 150, a first ejector tube 151, a second air mixing chamber 160 and a second ejector tube 161. The first air mixing chamber 150 and the second air mixing chamber 161 are relatively independent.

[0094] The two ends of the first ejector tube 151 are respectively connected to the first air mixing chamber 150 and the first air inlet 110, and the two ends of the second ejector tube 161 are respectively connected to the second air mixing chamber 160 and the second air inlet 120, and the multiple first air outlet channels 130 are connected to the first air mixing chamber 150, and the multiple second air outlet channels 140 are connected to the second air mixing chamber 160.

[0095] Specific combination Figures 7 to 9As shown, the burner head 100 is a cavity structure, in which relatively independent first air mixing chamber 150 and second air mixing chamber 160 are respectively provided; the first air inlet 110 is connected to the first air mixing chamber 150 through a first ejector tube 151, and multiple first air outlet channels 130 are connected to the first air mixing chamber 150; the second air inlet 120 is connected to the second air mixing chamber 160 through a second ejector tube 161, and multiple second air outlet channels 140 are all connected to the second air mixing chamber 160. After a portion of the gas is ejected through the first air inlet 110 and the first ejector pipe 151, it mixes with air and enters the first air mixing chamber 150. It then passes through the first air outlet 130 to reach the inner fire cover 310, where it is burned through the multiple inner fire cover fire holes 311. Another portion of the gas is ejected through the second air inlet 120 and the second ejector pipe 161. It then passes through the second air outlet 140 to reach the outer fire cover 320, where it is burned through the multiple outer fire cover fire holes 321. The gas diffuses within the first and second air mixing chambers 150, 160, before reaching the inner and outer fire covers 310, 320, and then combusting. A certain amount of gas is stored in the first and second air mixing chambers 150, 160, allowing the gas and air to be fully mixed within them, ensuring full combustion of the gas and improving gas utilization.

[0096] In an optional technical solution of this embodiment, the bottom wall of the first air mixing chamber 150 and the bottom wall of the second air mixing chamber 160 are both arranged in a spiral shape.

[0097] Specific combination Figure 3 As shown, the bottom wall of the first air mixing chamber 150 and the bottom wall of the second air mixing chamber 160 are both set to a spiral shape, which can improve the fluidity of the gas after entering the first air mixing chamber 150 and the second air mixing chamber 160, making the flow of the gas in the first air mixing chamber 150 and the second air mixing chamber 160 smoother, avoiding the occurrence of gas blockage when the first air mixing chamber 150 and the second air mixing chamber 160 provide gas to the inner fire cover 310 and the outer fire cover 320, further improving the stability of the gas combustion and enhancing the user experience.

[0098] In an optional technical solution of this embodiment, the secondary air channel 400 includes an inner channel 410 , an outer channel 420 and a main channel 430 ;

[0099] The inner channel 410 is connected to multiple inner fire cover fire holes 311 respectively, and the outer channel 420 is connected to multiple inner fire cover oxygen supply holes 312 and multiple outer fire cover fire holes 321 respectively, and the inner channel 410 and the outer channel 420 are connected, and the inner channel 410 and the outer channel 420 are both connected to the main channel 430.

[0100] Specific combination Figures 1 to 3 and Figure 7 and Figure 8As shown, a main channel 430 is formed between the gas distribution assembly 210 and the burner head 100, an inner channel 410 is formed between the multiple first gas outlet channels 130, and an outer channel 420 is formed between the multiple first gas outlet channels 130 and the multiple second gas outlet channels 140. The inner channel 410 and the outer channel 420 are both connected to the main channel 430, and the inner channel 410 and the outer channel 420 are connected to each other. The inner channel 410 is connected to the fire hole 311 of the inner fire cover, and the outer channel 420 is connected to the oxygen supply hole 312 of the inner fire cover and the fire hole 321 of the outer fire cover. The oxygen supply hole 322 of the outer fire cover is connected to the outside. During gas combustion, the inner channel 410, outer channel 420, and main channel 430 provide secondary air. The inner channel 410 supplies air to the ends of the flames on the inner fire cover fire hole 311; the outer channel 420 supplies air to the ends of the flames on the outer fire cover fire hole 321. Simultaneously, air is supplied to the base of the flames on the inner fire cover fire hole 311 through the inner fire cover oxygen supply holes 312; and air from the environment is supplied to the base of the flames on the outer fire cover fire hole 321 through the outer fire cover oxygen supply holes 322. The secondary air channels and oxygen supply holes work together to provide sufficient air supply for gas combustion, further improving gas utilization and reducing energy loss.

[0101] In an optional technical solution of this embodiment, the furnace head 100 further includes an electrode 170 and a galvanic couple 180 , and the electrode 170 and the galvanic couple 180 are both arranged at one end of the furnace head 100 close to the gas separation component 210 .

[0102] Specific combination Figure 7 As shown, electrode 170 and galvanic couple 180 are located near the first gas outlet 130 at one end of the burner 100, near the gas distribution assembly 210. During use, electrode 170 ignites the gas, ensuring proper combustion. During normal combustion, galvanic couple 180 maintains a constant gas supply, ensuring proper combustion. In the event of an abnormal flameout, the thermoelectric potential of galvanic couple 180 dissipates, shutting off the gas flow and preventing potential hazards, thus enhancing safety during use.

[0103] The gas stove provided in this embodiment includes a burner. Since the gas stove includes all the structures of the burner, the gas stove provided in this embodiment includes all the beneficial effects of the above-mentioned burner.
