[0026] See Figures 1 to 4, an embodiment of the present utility model provides a flame distributor, which includes a flame distributing base 200 and an outer ring flame cover 230. The flame distributing base 200 includes opposite first and second surfaces, the first and second surfaces are distributed vertically, the first surface is located below the second surface. There is an annular outer ring gas distribution groove 210 on the second surface, and an outer ring air inlet 260 communicating with the outer ring gas distribution groove 210 on the first surface. On the inner wall surface of the outer ring gas distribution groove 210, there are a first connection seat 221 and a second connection seat 222. The first connection seat 221 is arranged at the outer ring air inlet 260, and the second connection seat 222 is arranged on the other side away from the outer ring air inlet 260; The outer ring flame cover 230 is arranged on the second surface of the flame distributing base 200, the outer ring flame cover 230 covers the outer ring gas distribution groove 210, there are flame holes 270 on the outer ring flame cover 230, and the outer ring flame cover 230 is connected to the flame distributing base 200 through a first screw 300 passing through the first connection seat 221 and a second screw 400 passing through the second connection seat 222.

[0027] In the embodiment of the present utility model, the first connection seat 221 is arranged at the outer ring air inlet 260, which is the starting point of the combustion gas flowing in the outer ring gas distribution groove 210, and the second connection seat 222 is located on the other side opposite to the outer ring air inlet 260, which is the end point of the flow in the outer ring gas distribution groove 210. It avoids the flow path of the combustion gas along the outer ring gas distribution groove 210, reduces the obstruction to the flow of the combustion gas, can improve the uniformity of the combustion gas in the outer ring gas distribution groove 210, and improves the uniformity of the flame.

[0028] In some embodiments, referring to Figure 1 and Figure 3 , the first connection seat 221 and the second connection seat 222 are located on the line connecting the center of the outer ring gas distribution groove 210 and the center of the outer ring air inlet 260. The line connecting the center of the outer ring gas distribution groove 210 and the center of the outer ring air inlet 260 divides the outer ring gas distribution groove 210 into a counterclockwise path and a clockwise path with equal distances. The first connection seat 221 and the second connection seat 222 are located on the line connecting the center of the outer ring gas distribution groove 210 and the center of the outer ring air inlet 260, which can make the flow rates of the combustion gas along the counterclockwise path and the clockwise path basically the same, so that the combustion gas can be evenly distributed in the outer ring gas distribution groove 210 at a relatively fast speed, and improve the phenomenon of uneven flame caused by uneven distribution of the combustion gas.

[0029] In some embodiments, referring to Figure 4 , the outer ring gas distribution groove 210 includes a first inner wall surface 213, a second inner wall surface 214 and a bottom surface 215. The first inner wall surface 213 surrounds the second inner wall surface 214, and the bottom surface 215 connects the first inner wall surface 213 and the second inner wall surface 214. The first inner wall surface 213, the second inner wall surface 214 and the bottom surface 215 enclose the outer ring gas distribution groove 210.

[0030] The first connecting seat 221 can be disposed on the second inner wall surface 214, or as Figure 4 shown, the first connecting seat 221 is disposed on the first inner wall surface 213. Disposing the first connecting seat 221 on the second inner wall surface 214 can avoid interfering with the distribution of the flame holes 270 on the outer ring burner cap 230, simplify the structure of the outer ring burner cap 230, and make the design of the outer ring burner cap 230 simple.

[0031] The second connecting seat 222 can be disposed on the second inner wall surface 214, or as Figure 4 shown, the second connecting seat 222 is disposed on the first inner wall surface 213. Disposing the second connecting seat 222 on the second inner wall surface 214 can avoid interfering with the distribution of the flame holes 270 on the outer ring burner cap 230, simplify the structure of the outer ring burner cap 230, and make the design of the outer ring burner cap 230 simple.

[0032] In some embodiments, referring to Figures 1 to 4 , there is a first distance between the first connecting seat 221 and the bottom surface 215. The first connecting seat 221 is not connected to the bottom surface 215, so that there is a first distance between the first connecting seat 221 and the bottom surface 215, thereby reducing the blockage of the combustion gas. The first connecting seat 221 is suspended above the outer ring air inlet 260, and the combustion gas entering from the outer ring air inlet 260 has a certain rising space in the vertical direction to reach the first connecting seat 221, reducing the resistance of the combustion gas at the outer ring air inlet 260, not affecting the intake of primary air, and not forming an obstacle to the combustion gas in the flow path of the combustion gas. The first connecting seat 221 is located above the outer ring air inlet 260, and the first screw 300 can extend into the first connecting seat 221 from the outer ring air inlet 260 and be threadedly connected to the outer ring burner cap 230.

[0033] In some embodiments, referring to Figure 3 , one side of the first connecting seat 221 facing the bottom surface 215 has a concave cavity 2211, and a first through hole 2212 is provided in the concave cavity 2211. The screw rod of the first screw 300 passes through the first through hole 2212 and is threadedly connected to the outer ring burner cap 230, and the nut of the first screw 300 is located in the concave cavity 2211. The nut of the first screw 300 is accommodated in the concave cavity 2211, reducing the blockage of the first screw 300 to the combustion gas.

[0034] In some embodiments, referring to Figure 4 , the top surface of the first connecting seat 221 can be flush with the upper edge of the second inner wall surface 214. The top surface of the first connecting seat 221 being flush with the upper edge of the second inner wall surface 214 can maximize the distance between the first connecting seat 221 and the bottom surface 215 and facilitate the connection with the outer ring burner cap 230.

[0035] In some embodiments, referring to Figure 4, the second connecting seat 222 is connected to the bottom surface 215. The second connecting seat 222 has a second through hole 2221 that communicates the first surface and the second surface. The second screw 400 passes through the second through hole 2221 and is threadedly connected to the outer ring burner cap 230. The second through hole 2221 communicates the first surface and the second surface, facilitating the connection between the second screw 400 and the outer ring burner cap 230.

[0036] In some embodiments, the depth of the outer ring gas distribution groove 210 gradually decreases in a direction away from the outer ring air inlet 260. By providing a gradient structure on the bottom surface 215 of the outer ring gas distribution groove 210 at the air inlet, the depth of the outer ring gas distribution groove 210 is made different. Among them, the depth of the outer ring gas distribution groove 210 gradually decreases in a direction away from the outer ring air inlet 260, thereby increasing the depth at the outer ring air inlet 260, increasing the space of the outer ring gas distribution groove 210 corresponding to the air inlet, facilitating the combustion gas to flow to the remaining space of the outer ring gas distribution groove 210, converting the velocity field into a pressure field, reducing the resistance of the combustion gas at the air inlet, increasing the amount of primary air inhaled, making the combustion sufficient, reducing the flue gas, and improving the thermal efficiency.

[0037] In some embodiments, the region where the depth of the outer ring gas distribution groove 210 changes can be a part or all of the entire outer ring gas distribution groove 210. In an exemplary embodiment, the region where the depth of the outer ring gas distribution groove 210 changes can account for one-fourth, one-third, two-fifths, one-half, two-thirds, etc. of the entire outer ring gas distribution groove 210.

[0038] In some embodiments, referring to Figure 1 and Figure 2 , the burner further includes a flow dividing baffle 100. The flow dividing baffle 100 is disposed in the outer ring gas distribution groove 210 and is opposite to the air inlet. The flow dividing baffle 100 axially divides the outer ring gas distribution groove 210 into two layers, forming a first cavity 211 and a second cavity 212 respectively. The air inlet communicates with the first cavity 211, the flame holes 270 communicate with the second cavity 212, and the flow dividing baffle 100 has a flow dividing hole 120 that communicates the first cavity 211 and the second cavity 212.

[0039] The flow dividing baffle 100 divides the outer ring gas distribution groove 210 into a first cavity 211 and a second cavity 212. The flow dividing baffle 100 blocks the combustion gas entering from the air inlet, causing the combustion gas to flow along the first cavity 211 away from the air inlet side and flow into the second cavity 212 through the flow dividing holes 120. The combustion gas can be evenly distributed in the second cavity 212. The air pressure and flow velocity inside the entire outer ring gas distribution groove 210 of the burner are uniform, ensuring the uniformity of the flame and improving the phenomenon of uneven flame caused by uneven distribution of the combustion gas. In addition, the flow dividing baffle 100 prevents the combustion gas from directly rushing upward to the flame holes 270 from the outer ring air inlet 260, slowing down the air flow velocity at the flame holes 270 opposite to the air inlet and improving the situation of flame lift caused by the too fast air flow at the flame holes 270 above the vicinity of the outer ring air inlet 260.

[0040] In some embodiments, the flow dividing baffle 100 has an avoidance hole corresponding to the first connection seat 221. Through the avoidance hole, the flow dividing baffle 100 can be easily installed into the outer ring gas distribution groove 210.

[0041] The flow dividing baffle 100 can be an annular structure or a semi-annular structure. The flow dividing baffle 100 is arranged above the outer ring air inlet 260, guiding the flow direction of the combustion gas at the outer ring air inlet 260 and its vicinity, evenly dispersing the combustion gas into the inner part of the outer ring gas distribution groove 210 to make the flame uniform. Adopting a semi-annular structure for the flow dividing baffle 100 can save materials and achieve the effect of uniform distribution of the combustion gas.

[0042] In the embodiments of the present invention, the burner in the embodiments of the present invention may further have an inner ring gas distribution groove 240, and an inner ring burner cap 250 is provided on the inner ring gas distribution groove 240. The outer ring gas distribution groove 210 is arranged to surround the inner ring gas distribution groove 240.

[0043] In some embodiments, the flow dividing holes 120 can be used to change the flow direction of the combustion gas entering the second cavity 212, so that the flow direction of the combustion gas entering the second cavity 212 is not parallel to the center line of the outer ring gas distribution groove 210. The non-parallelism between the flow direction of the combustion gas entering the second cavity 212 and the center line of the outer ring gas distribution groove 210 can adjust the flow velocity at the air inlet, facilitating the uniform distribution of the combustion gas in the second cavity 212, thereby making the flame uniform.

[0044] The diverter hole 120 can be divided into two parts, one of which is the first diverter hole 120, and the other is the second diverter hole 120. The tangential component of the first diverter hole 120 is in the clockwise direction, which is conducive to the combustion gas flowing in the clockwise direction away from the air inlet. The tangential component of the second diverter hole 120 is in the counterclockwise direction, which is conducive to the combustion gas flowing in the counterclockwise direction away from the air inlet. After the combustion gas entering the air inlet enters the second cavity 212, a part of it quickly diffuses to the far end in the clockwise direction, and the other part quickly diffuses to the far end in the counterclockwise direction, which is conducive to the uniform distribution of the combustion gas in the second cavity 212, so that the flame is uniform. And it can make the speed of the combustion gas entering the second cavity 212 vertically upward, slow down the flow rate of the combustion gas in the fire hole 270 near the air inlet, and improve the fire separation phenomenon.

[0045] In some embodiments, the flow dividing baffle 100 is plugged with the flame dividing seat 200. In a specific implementation, the flow dividing baffle 100 has a plug 140, and the inner wall surface of the outer ring gas dividing groove 210 has a socket 280, and the socket 280 has a socket adapted to the plug 140.

[0046] The socket 280 is directly at a second distance from the bottom surface 215 of the outer ring gas distribution groove 210 . The socket 280 is suspended on the inner wall surface of the outer ring gas distribution groove 210 , which can avoid hindering the flow of combustion gas in the outer ring gas distribution groove 210 .

[0047] The free end of the plug 140 has an axial notch, which divides the free end of the plug 140 into two parts. The two parts have protrusions on the sides facing away from the notch, and the protrusions form a hook structure with the plug 140. The socket is a through hole. When the plug 140 is inserted into the socket, the two parts of the free end are deformed in the direction of the notch. When plugged into the target position, the two parts of the free end recover their deformation, and the protrusions are engaged with the lower edge of the socket to achieve engagement. When disassembling, the two parts of the free end are deformed in the direction of the notch, and the protrusions are released from the socket 280, so that the diverter baffle 100 can be disassembled.
