In this application, by axially setting a first air channel 101 and a through hole 210 in the middle of the fire distributor 1 and the fire cover 2, respectively, and setting the anti-overflow component 3 cover on the top of the through hole 210, the secondary air supply is immediately guaranteed, and the water or soup overflowing from the pot can be prevented from overflowing into the central air channel of the burner, making the product cleaner, easier to clean, with a longer product life and a better user experience. In addition, the secondary air channel 102 arranged radially on the fire distributor 1 can provide sufficient air for the first air channel 101, thereby improving the thermal efficiency of the combustion gas.

[0068] The fire cover 2 in this application is an integrated structure. Figure 1-4 The cover plate 21 shown in Figures 13 is installed on the top of the fire divider 1. Compared with the conventional separated inner fire cover and outer fire cover, the upper surface of the cover plate 21 of the present application is not only a smooth surface, but also the upper surface of the cover plate 21 is inclined upward from the outside to the inside, and its inclination angle gradually increases as it approaches the central axis of the fire cover 2, so that the overflow flows quickly to the outside of the burner. Therefore, the fire cover 2 of the present application integrates the functions of the conventional inner fire cover and the outer fire cover, has good integrity, no cleaning dead corners, and is easier to clean.

[0069] In a preferred embodiment of the present invention, Figure 1-10 The fire spreader 1 shown includes a first fire spreader plate 11, a second fire spreader plate 12 and a third fire spreader plate 13. A first air vent 110 for replenishing air is axially opened in the middle of the first fire spreader plate 11. The second fire spreader plate 12 is detachably connected to the middle of the first fire spreader plate 11, and a second air vent 121 connected to the first air vent 110 is axially opened, wherein the first air vent 110 and the second air vent 121 form a first air channel 101. The third fire spreader plate 13 is sleeved on the outer periphery of the second fire spreader plate 12 and is detachably connected to the top of the first fire spreader plate 11. The outer periphery of the fire cover 2 is connected to the third fire spreader plate 13. The first flame distribution plate 11 is detachably connected to the burner head 5. The middle portion of the first flame distribution plate 11 is connected to the second flame distribution plate 12 to form an inner ring channel and a first air channel 101. The outer periphery of the first flame distribution plate 11 is detachably connected to the third flame distribution plate 13 to form an outer ring channel. The outer ring channel, the inner ring channel, and the first air channel 101 are arranged in sequence from the outside to the inside. The flame distributor 1 is formed by detachably connecting the first flame distribution plate 11, the second flame distribution plate 12, and the third flame distribution plate 13. The installation structure is simple and convenient for maintenance and cleaning of the product.

[0070] In a preferred embodiment of the present invention, Figure 1-10 A second air channel 103 is formed between the second ignition distribution plate 12 and the first ignition distribution plate 11, extending radially along the first ignition distribution plate 11. A third air channel 104 is formed between the third ignition distribution plate 13 and the first ignition distribution plate 11, extending radially along the first ignition distribution plate 11. The third air channel 104 communicates with the second air channel 103 to form a secondary air channel 102. The third air channel 104 and the second air channel 103 form a radially extending secondary air channel 102, which communicates with the first air channel 101. This provides sufficient secondary air for gas combustion, resulting in more complete combustion, higher thermal efficiency, and lower CO emissions.

[0071] In a preferred embodiment of the present invention, Figure 1-10 The first fire distribution disk 11 shown is provided with an outer ring air outlet group 111, an inner ring air outlet group 112 and a first air vent 110 from the outside to the inside. The outer ring air outlet group 111 includes a plurality of outer ring air outlets 1111, and the inner ring air outlet group 112 includes a plurality of inner ring air outlets 1121. The outer ring air outlets 1111 and the inner ring air outlets 1121 extend axially to the top of the first fire distribution disk 11. The second air channel 103 is formed between the second fire distribution disk 12, the first fire distribution disk 11 and the two adjacent inner ring air outlets 1121, and the third air channel 104 is formed between the third fire distribution disk 13, the first fire distribution disk 11 and the two adjacent outer ring air outlets 1111. Figure 4-10It is not difficult to see that the multiple outer ring air outlet holes 1111 of the present application are evenly and symmetrically distributed along the center of the first fire distribution disk 11 and form an outer ring air outlet end connected to the external mixing chamber of the burner head 5, and the two adjacent outer ring air outlet holes 1111 and the first fire distribution disk 11 form an outer ring air channel with an opening at the top; the multiple inner ring air outlet holes 1121 are located on the inner side of the multiple outer ring air outlet holes 1111 and are evenly and symmetrically distributed along the center of the first fire distribution disk 11, and the two adjacent inner ring air outlet holes 1121 and the first fire distribution disk 11 form an inner ring air channel with an opening at the top. As the second fire distribution disk 12 and the third fire distribution disk 13 are respectively assembled with the first fire distribution disk 11, a third air channel 104 is formed between the third fire distribution disk 13, the first fire distribution disk 11 and the two adjacent outer ring air outlet holes 1111, and a second air channel 103 is formed between the second fire distribution disk 12, the first fire distribution disk 11 and the two adjacent inner ring air outlet holes 1121, wherein the second air channel 103 and the third air channel 104 correspond to each other and are connected to each other to form a secondary air channel 102, so as to provide sufficient air for the central air channel of the burner and improve combustion efficiency.

[0072] In a preferred embodiment of the present invention, Figure 1-6 , 9 and 10 include a disk body 133, the disk body 133 is provided with a first outer ring hole 131 corresponding to each outer ring air outlet hole 1111, a second outer ring hole 132 connected to the top of all the first outer ring holes 131, the first outer ring hole 131 is arc-shaped, the second outer ring hole 132 is annular, the second outer ring hole 132 and each first outer ring hole 131 are coaxially overlapped and connected, the second outer ring hole 132, multiple first outer ring holes 131 and outer ring air outlet holes 1111 together form an outer ring channel; wherein, the first fire distribution disk 11, the disk body 133 and the corresponding two adjacent first outer ring holes 131 form a third air channel 104. From Figure 4 、 5As can be seen from Figures 9 and 10, a plurality of first outer ring holes 131 are provided on the periphery of the disk body 133, and the plurality of first outer ring holes 131 correspond to and are connected to the outer ring air outlet holes 1111 one by one, and the hole wall of each first outer ring hole 131 extends downward and is connected to the outer ring air outlet hole 1111, wherein two adjacent first outer ring holes 131 and the disk body 133 are respectively surrounded by the corresponding two outer ring air outlet holes 1111 and the first flame distribution disk 11 to form a third air channel 104. This design can effectively increase the intake amount of secondary air, because the gas temperature near the center of the burner is higher, the gas is heated and flows upward, forming a pressure difference. At this time, the separate secondary air channel 102 can quickly inhale cold air to make the combustion more complete. Of course, from a structural perspective, the flow area of the secondary air channel 102 can be gradually reduced along the direction of the air flow, and the flow area of the first air channel 101 can be larger than the area of the air outlet end of the secondary air channel 102. This can effectively increase the air flow velocity entering the first air channel 101 and replenish sufficient air for the burner.

[0073] Preferably, a step 1311 with an opening facing downward is provided at the bottom of the inner ring wall of the first outer ring hole 131, and the step 1311 is sleeved on the top of the inner wall of the outer ring air outlet 1111, so that the connection between the third fire distribution disk 13 and the first fire distribution disk 11 is more stable.

[0074] In a preferred embodiment of the present invention, Figure 1-7 The burner shown also includes an ignition needle 4 located below the cover plate 21. The first ignition distributor plate 11 includes a connection portion between the outer ring air outlet holes 1111 and the inner ring air outlet holes 1121. The ignition needle 4 is detachably connected to one side of the connection portion near one of the secondary air passages 102. Hiding the ignition needle 4 beneath the fire cover 2 prevents contamination, improves ignition efficiency, and extends the service life of the ignition needle 4.

[0075] In a preferred embodiment of the present invention, Figure 1-5 The second outer ring hole 132 shown has a first notch 1321 extending radially along the third ignition distributor 13 on the side near the ignition needle 4. A disc 133 is located below this first notch 1321 and, together with the first notch 1321 and the ignition cover 2, forms a first combustion space 130 for combustion in the outer ring channel. Because this first combustion space 130 is located near the outside of the ignition needle 4, the moment the ignition needle 4 is ignited, the gas in this first combustion space 130 is burned and transferred to the outer ring gas mixing chamber, enabling the flame from the ignition needle 4 to be transferred outward. Simultaneously, the change in pressure from the outside air after combustion allows for rapid replenishment of secondary air, improving the thermal efficiency of the outer ring.

[0076] In a preferred embodiment of the present invention, Figure 1-5The second ignition distribution plate 12 shown in FIG7 is provided with an inner ring groove 122. The inner ring groove 122 defines an inner ring air passage 1220 that connects to the inner ring air outlet 1121. The interior of the inner ring air outlet 1121 and the inner ring air passage 1220 form an inner ring passage. The bottom of the inner ring groove 122, on the side near the ignition needle 4, is recessed upward to form a combustion groove 123 with the notch facing downward. The interior of the combustion groove 123 is connected to form a second combustion space 120. In the present application, the second combustion space 120 is located inside the ignition needle 4 and connects to the second air passage 103, or secondary air passage 102. When the ignition needle 4 ignites the gas in the second combustion space 120, the secondary air passage 102 can provide sufficient air to the second combustion space 120, improving combustion stability. The present application cleverly designs the position of the ignition needle, which not only effectively prevents the ignition needle from being blocked, but also allows the flame to be transmitted both outward and inward simultaneously, achieving efficient ignition of the inner and outer rings.

[0077] In a preferred embodiment of the present invention, Figure 1-5 The wall of the combustion groove 123 shown in FIG7 is provided with at least one first flame transfer hole 1231 and an ignition hole group 1232. The first flame transfer hole 1231 and the ignition hole group 1232 respectively communicate with the inner annular air passage 1220 and the interior of the combustion groove 123, thereby forming a second combustion space 120 within the combustion groove 123. The air intake direction of the first flame transfer hole 1231 is perpendicular to the airflow direction of the inner annular air passage 1220, and the first flame transfer hole 1231 includes an elongated hole section located on the side wall of the combustion groove 123 and an arcuate hole section located on the side of the inner annular groove 122 near the ignition needle 4. In addition, there are no less than one ignition hole group 1232, preferably two, three, four, or six, and more preferably, the first fire transfer holes 1231 are inserted at equal intervals between multiple ignition hole groups 1232. For example, a first fire transfer hole 1231 is set between two adjacent ignition hole groups 1232, or a first fire transfer hole 1231 is set between every two ignition hole groups 1232. Of course, a first fire transfer hole 1231 can also be set between every three ignition hole groups 1232. This application does not impose any restrictions on this, as long as the efficiency of flame transmission to the inner ring air duct 1220 can be guaranteed to improve the ignition efficiency.

[0078] In addition, each ignition hole group 1232 includes a plurality of evenly distributed ignition holes. The multiple ignition holes on each ignition hole group 1232 are arranged at equal intervals from the side of the inner ring groove 122 close to the ignition needle 4 to the inside of the combustion groove 123. When the ignition needle 4 ignites, the gas at the ignition hole is ignited, and the flame can propagate in two directions: outward to the outer ring fire holes and inward to the inner ring fire holes. The product has a higher ignition success rate and a higher fire transmission success rate.

[0079] In a preferred embodiment of the present invention, Figure 1-7The inner annular groove 122 shown includes an inner sidewall 1221 located on its inner side. The inner sidewall 1221 is provided with an inwardly recessed groove 1222 on a side near the combustion groove 123. A plurality of second flame transmission holes 12221 are provided on a side of the groove 1222 near the first air channel 101. The second flame transmission holes 12221 connect the first air channel 101 and the inner annular air channel 1220. In the present application, the groove 1222 can be U-shaped or V-shaped. The sidewalls of the groove 1222 are inclined outward from the bottom of the groove 1222 to both sides. This allows the air in the first air channel 101 to quickly enter the inner annular air channel through the second flame transmission holes 12221 and the sidewalls of the groove 1222, thereby making the combustion of the gas more complete and improving the combustion efficiency of the burner.

[0080] In a preferred embodiment of the present invention, Figure 1-7 The bottom of the cover plate 21 is provided with a first annular wall 22, a second annular wall 23, a third annular wall 24 and a fourth annular wall 25 arranged in sequence from the outside to the inside along its radial direction. The first annular wall 22 and the second annular wall 23 are respectively connected to the top of the outer ring channel and form an outer ring air mixing chamber therewith. The third annular wall 24 and the fourth annular wall 25 are respectively connected to the top of the inner ring channel and form an inner ring air mixing chamber therewith.
