After the utility model adjusts the gas intake amount through the regulating valve, the gas enters from the gas input channel 11 and is diverted to each nozzle 3 through multiple gas distribution channels 12, and then is sprayed into the corresponding venturi tubes 4 at high speed, so that negative pressure is generated in the venturi tube 4 to suck air from the intake gap 5 between the intake end of the venturi tube 4 and the jet end of the nozzle 3 to mix with the gas, and finally the mixed gas is sprayed out from the various fire holes 21 of the igniter 2 and ignited by the igniter 6. The overall relatively simple structure can realize the burner with single intake and multiple outlets and high combustion power, and it is easy to manufacture.

[0033] Specifically, a regulating valve 9 for regulating the amount of gas intake is provided on the gas input channel 11, and the regulating valve 9 includes a valve body 91, on which a gas inlet 911, a gas outlet 912 connected to the gas input channel 11, and a valve cavity 913 connecting the gas inlet 911 and the gas outlet 912 are provided. A valve core 92 is relatively rotatably provided in the valve cavity 913, and two opposite side walls of the valve core 92 are provided with regulating holes 921 that can be respectively connected to the gas inlet 911 and the gas outlet 912 when the valve core 92 rotates. A connecting cavity 922 connecting the two regulating holes 921 is provided in the valve core 92, and a valve stem 923 is provided on the valve core 92, one end of which passes through the valve cavity 913 and can drive the valve core 92 to rotate so that the connecting ports formed between the two regulating holes 921 and the gas inlet 911 and the gas outlet 912 are gradually opened or closed.

[0034] Furthermore, the nozzle 3 is provided with an air regulating device 7 for regulating the size of the air intake gap 5. The utility model can adjust the size of the air intake gap 5 through the air regulating device 7, thereby controlling the amount of air entering, so that the appropriate amount of air is fully mixed with the fuel gas, promoting full combustion and flame stability.

[0035] The air regulating device 7 includes an air regulating disk 71 that can move up and down along the nozzle 3 and an adjusting component 72 that fixes the air regulating disk 71 when the air regulating disk 71 moves. The air regulating disk 71 is provided with a plurality of through holes 711 for the nozzles 3 to pass through one by one. The air intake gap 5 is provided between the air regulating disk 71 and the air intake end of the venturi tube 4.

[0036] Specifically, the jet end of the nozzle 3 is provided with a first stud 32 passing through the through hole 711, and the adjustment assembly 72 includes a first nut 721 threadedly connected to the first stud 32 and resting on the lower end surface of the gas regulating disk 71, and a second nut 722 threadedly connected to the first stud 32 and capable of pressing the gas regulating disk 71 against the first nut 721. When the first nut 721 is screwed to move the first nut 721 up and down along the first stud 32, the lower limit position of the gas regulating disk 71 is adjusted, so that the size of the intake gap 5 between the gas regulating disk 71 and the intake end of the venturi tube 4 can be adjusted. After the required intake gap 5 is adjusted, the second nut 722 is screwed so that the gas regulating disk 71 is clamped between the first nut 721 and the second nut 722.

[0037] like Figure 5 As shown, the gas regulating disk 71 is provided with a plurality of regulating plates 712 corresponding to the venturi tubes 4 one by one, and the adjacent regulating plates 712 are connected by connecting blocks 713, and the through hole 711 is provided in the middle of the regulating plates 712. Specifically, the gas regulating disk 71 is provided with an regulating plate 712 in the center, and eight regulating plates 712 are arranged in a circle on the outside. Correspondingly, the nozzle 3 on the gas distributor seat 1 and the venturi tube 4 in the ignition distributor 2 are arranged in the same manner.

[0038] like Figure 3 As shown, the venturi tube 4 extends vertically, the fire hole 21 is arranged on the upper end surface of the ignition distributor 2, a plurality of secondary air supply holes 22 are arranged on the upper end surface of the ignition distributor 2 to supply air to the fire hole 21, a plurality of air inlet holes 23 are arranged on the side wall of the ignition distributor 2, a cavity 24 connecting the air inlet holes 23 and the secondary air supply holes 22 is arranged in the ignition distributor 2, and the venturi tube 4 is installed in the cavity 24. When the commercial stove burner is working, the surrounding air can enter the cavity 24 from the air inlet holes 23 on the side wall of the ignition distributor 2, and then be supplemented to the vicinity of the fire hole 21 at the end of the ignition distributor 2 through the secondary air supply holes 22, so that the gas burns more fully and the combustion effect is better.

[0039] In order to prevent the nozzle 3 from being blocked, a guide structure 8 is provided in the fire hole 21 to guide the dripping juice to the inner wall of the fire hole 21 .

[0040] Specifically, the flow guiding structure 8 includes at least two flow guiding blocks 81 intersecting in the middle and connected at both ends to the inner wall of the fire hole 21, and the lower end surface of the flow guiding block 81 gradually slopes downward from the middle to both ends. In the kitchen, liquids such as water and soup may fall on the stove. When the juice drips on the flow guiding structure 8, due to the wall attachment effect, the juice flows along the inclined surface of the flow guiding block 81, so it will not drip onto the nozzle 3 located below the center of the fire hole.

[0041] Furthermore, the edge of the jet port 31 of the nozzle 3 is provided with a conical surface 33 which can guide the juice falling on the nozzle 3 to the surroundings, so that the liquid falling on the nozzle can flow down along the conical surface and is not easy to block the air outlet of the nozzle.

[0042] In the present invention, the nozzle 3 is also detachable, and can be easily replaced or removed for cleaning. Specifically, the lower end of the nozzle 3 is threadedly connected to the mounting screw of the gas distribution channel, and the nozzle 3 is provided with a hexagonal boss 31 that can be rotated by a tool. When the hexagonal boss is screwed with an external hexagonal wrench, the nozzle rotates, and the external threaded column at the lower end can be screwed into or out of the mounting screw, completing the installation and removal of the nozzle.

[0043] like Figure 3 As shown, a positioning hole 25 is provided on the lower end face of the ignition divider 2, and a positioning step 13 for the lower end face of the ignition divider 2 to be positioned against and a positioning column 14 inserted into the positioning hole 25 is provided on the gas divider seat 1. The ignition divider 2 can be installed on the gas divider seat 1 very conveniently and quickly.

[0044] Embodiment 2:

[0045] like Figures 7 to 9As shown, the main difference between the second embodiment and the first embodiment is that the structure of the adjustment component 72 is different. The adjustment component 72 of this structure can easily adjust the position of the gas adjustment disk 71, thereby adjusting the size of the intake gap 5. Specifically, the gas separation seat 1 is provided with a second stud 15, and two second studs 15 are provided on the edge of the gas separation seat 1. The adjustment component 72 includes a rotating paddle 723 supported on the lower end surface of the gas adjustment disk 71 and having a threaded hole in the middle thereof that is threadably matched with the second stud 15, and a spring 724 that is sleeved on the second stud 15 and can press the upper end surface of the gas adjustment disk 71 to press the gas adjustment disk 71 against the rotating paddle 723. The rotating paddle 723 can be rotated by hand. When the rotating paddle 723 moves upward along the second stud 15 during rotation, the rotating paddle 723 drives the gas regulating disk 71 to rise, and the air intake gap 5 becomes smaller. When the rotating paddle 723 is rotated in the opposite direction, the rotating paddle 723 moves downward along the second stud 15 during rotation, and the spring 724 presses the upper end surface of the gas regulating disk 71 to make the gas regulating disk 71 also descend with the rotating paddle 723. At this time, the air intake gap 5 becomes larger, allowing more air to enter the venturi tube 4 and mix with the fuel gas.
