[0002] The burner is generally provided with multiple gas chambers to form a multi-ring flame. In order to make the gas and air mix more fully, each gas chamber on some burners will be connected to multiple ejector tubes. Generally, it is necessary to set multiple outlet pipes on the gas valve module to correspond to the ejector tubes one by one. As the number of outlet pipes of the gas valve module increases, the processing difficulty and cost of the gas valve module will increase. Moreover, the manufacturer cannot make the gas valve module that normally corresponds to the number of single ejector tubes and multiple ejector tubes into standard universal parts, which increases production costs.

[0003] Therefore, further improvement is needed. Summary of the Invention

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] First embodiment:

[0032] See also Figure 1-Figure 3The gas distributor of the multi-ejector burner comprises a burner module 1 and a gas valve module 2. The burner module 1 is provided with a plurality of gas distribution cavities, each of which is connected to a plurality of ejector tubes. The gas valve module 2 is provided with a plurality of gas outlet pipes 5 corresponding to the gas distribution cavities one by one. A gas distribution device 3 is connected between the gas outlet pipe 5 and the ejector tube. The gas inlet end of the gas distribution device 3 is connected to the gas outlet pipe 5. The plurality of ejector tubes connected to the same gas distribution cavity are respectively connected to the gas outlet end of the gas distribution device 3. An air distribution channel is connected between the air inlet end and the air outlet end of the device 3. A plurality of air outlet parts are provided at the position of the air outlet end of the air distribution device 3 corresponding to the air distribution channel. The air outlet parts are respectively connected to the corresponding ejection pipe bodies. By setting the air distribution device 3, a single air outlet pipe body 5 can output gas to multiple ejection pipe bodies at the same time. There is no need to additionally set an air outlet pipe body 5 on the gas valve module 2, and there is no need to change the structure of the gas valve module 2, thereby reducing its design and processing costs, making the gas valve module 2 a standard universal part, and reducing the manufacturer's production cost.

[0033] Furthermore, the air dividing cavity includes an inner ring air dividing cavity 11 and an outer ring air dividing cavity 12 . The inner ring air dividing cavity 11 is connected to two inner ring ejection tubes 41 , and the outer ring air dividing cavity 12 is connected to two outer ring ejection tubes 42 .

[0034] Under the condition of fixed flow rate, the mixed gas disperses and flows through multiple ejector tubes before entering the gas distribution cavity, which is equivalent to extending the overall mixing time by several times, thereby making the gas and air mix more fully, achieving better combustion effect and improving the energy efficiency of the product.

[0035] At the same time, compared with the design of a single ejector tube body corresponding to an air distribution cavity in the prior art, since the air distribution cavity enters each air distribution cavity through multiple ejector tube bodies respectively, the gas flow of a single ejector tube body is relatively reduced, so the inner diameter of the ejector tube body can be relatively reduced, the gas and air are fully mixed in the ejector tube body, and the depth of the air distribution cavity can also be relatively reduced, so that the thickness of the burner head module 1 becomes thinner, and the thickness of the corresponding gas stove can be reduced, thereby reducing the difficulty of assembly, improving the appearance grade of the product, and making the product have higher market added value. Of course, it can also be used in conjunction with the existing thicker gas stove without affecting the adaptability of the product.

[0036] Furthermore, a central gas cavity 13 is provided on the burner module 1, and the central gas cavity 13 is connected to a central ejector pipe 43. A central gas outlet pipe 53 is provided on the gas valve module 2, and the central gas outlet pipe 53 is connected to the central ejector pipe 43 through a gas distribution device 3.

[0037] Furthermore, the air outlet pipe body 5 includes an inner ring air outlet pipe 51 and an outer ring air outlet pipe 52, and the air distribution channel includes a first air distribution channel 31 and a second air distribution channel 32 arranged in sequence from bottom to top. The inner ring air outlet pipe 51 and the two inner ring ejection pipes 41 are respectively connected to the first air distribution channel 31, and the outer ring air outlet pipe 52 and the two outer ring ejection pipes 42 are respectively connected to the second air distribution channel 32. The first air distribution channel 31 and the second air distribution channel 32 can be processed and formed respectively by mold core pulling, which can be understood by those skilled in the art.

[0038] Furthermore, the gas separation device 3 is provided with a first air inlet 331 corresponding to the inner ring air outlet pipe 51, and the air outlet part includes two first air outlets 341 corresponding to the inner ring ejector pipe 41. The horizontal heights of the first air inlet 331 and the first air outlet 341 are consistent. The gas enters the gas separation device 3 from the inner ring air outlet pipe 51 through the first air inlet 331, and diffuses to the two first air outlets 341 under the action of the first gas separation channel 31 and enters the corresponding inner ring ejector pipe 41. Since the horizontal heights of the first air inlet 331 and the first air outlet 341 are consistent, the processing difficulty of the inner ring ejector pipe 41 is reduced, and the assembly between the inner ring ejector pipe 41 and the inner ring air outlet pipe 51 is more convenient, and the overall product is more beautiful.

[0039] Furthermore, the gas distribution device 3 is provided with a second air inlet 332 corresponding to the outer ring air outlet pipe 52, and the air outlet part includes two second air outlets 342 corresponding to the outer ring ejector pipe 42. The second air inlet 332 and the second air outlet 342 have the same horizontal height. The gas enters the gas distribution device 3 from the inner ring air outlet pipe 51 through the second air inlet 332, and diffuses to the two second air outlets 342 under the action of the second gas distribution channel 32 and enters the corresponding outer ring ejector pipe 42. Since the second air inlet 332 and the second air outlet 342 have the same horizontal height, the processing difficulty of the outer ring ejector pipe 42 is reduced, and the assembly between the outer ring ejector pipe 42 and the outer ring air outlet pipe 52 is more convenient, and the overall product is more beautiful.

[0040] Preferably, the overall horizontal heights of the central ejector tube 43, the inner ring ejector tube 41, the outer ring ejector tube 42 and the central air outlet tube 53, the inner ring air outlet tube 51, and the outer ring air outlet tube 52 are consistent, which can make the assembly between the burner head module 1 and the gas valve module 2 more convenient and the overall product more beautiful.

[0041] Second embodiment:

[0042] See also Figure 4 、 Figure 5, the difference between this embodiment and the first embodiment is that: the gas outlet pipe body 5 of the gas distributor of the multi-injector burner head of this invention is arranged in parallel with the first gas outlet hole 541 and the second gas outlet hole 542, and the gas distribution channel includes the first gas distribution channel 31 and the second gas distribution channel 32 with the same horizontal height. The first gas outlet hole 541 is connected to the central injector pipe 43, and the two inner ring injector pipes 41 are respectively connected to the first gas distribution channel 31, and the second gas outlet hole 542 and the two outer ring injector pipes 42 are respectively connected to the second gas distribution channel 32. Since the first gas distribution channel 31 and the second gas distribution channel 32 have the same horizontal height, the gas distribution device 3 can better utilize the horizontal space position, and the overall thickness is smaller, which can make the thickness of the corresponding gas stove smaller, reduce the difficulty of assembly, improve the appearance of the product, and make the product have higher market added value.

[0043] Furthermore, the two inner ring ejector tubes 41 and the two outer ring ejector tubes 42 are arranged side by side with each other, and the second gas distribution channel 32 includes two branch channels, and the branch channels are provided with branch air holes 321. The two branch air holes 321 form a connecting channel between the outer sides of the first gas distribution channel 31. The connecting channel and the two branch channels are combined to form a second gas distribution channel 32. When the gas enters one of the branch channels, the gas will enter the other branch channel from the connecting channel, so that the second gas distribution channel 32 is filled with gas as a whole and supplies gas to the two outer ring ejector tubes 42 at the same time.

[0044] The remaining undescribed parts are the same as those in the first embodiment and will not be repeated here.

[0045] Third embodiment:

[0046] See also Figure 6-Figure 9 The difference between this embodiment and the first embodiment is that the gas distribution device 3 of the multi-injector tube furnace head includes a main cavity, a first pipe 351 and a second pipe 352, and both ends of the first pipe 351 and the second pipe 352 are respectively provided with sealing plugs (not shown in the figure).

[0047] A blocking block 36 is provided in the first pipe 351 to form a front tube cavity 361 and a rear tube cavity 362 which are not connected to each other. The front tube cavity 361 is respectively connected to the second pipe 352 and the outer ring air outlet pipe 52. The second pipe 352 is connected to two second air outlets 342 corresponding to the outer ring ejection pipe 42.

[0048] like Figure 6 As shown, after the gas enters the first pipe 351 from the outer ring gas outlet pipe 52 , it enters the front tube cavity 361 and the second pipe 352 in sequence under the action of the blocking block 36 , and finally enters the outer ring ejector pipe 42 through the second gas outlet 342 .

[0049] The main cavity includes a central air guide cavity 371 , and the central air outlet pipe 53 is connected to a third air outlet 343 corresponding to the central ejection pipe 43 through the central air guide cavity 371 .

[0050] like Figure 8 As shown, the gas directly enters the central gas guide cavity 371 from the central gas outlet pipe 53 and finally enters the central ejector pipe 43 through the third gas outlet 343 .

[0051] The main cavity also includes an inner ring air guide cavity 372, which is not connected to the central air guide cavity 371. In an embodiment, the inner ring air guide cavity 372 and the central air guide cavity 371 can be disconnected by a baffle 373. The inner ring air guide cavity 372 is connected to the inner ring air outlet pipe 51 through the rear tube cavity 362. The inner ring air guide cavity 372 is connected to the first air outlet 341 corresponding to the two inner ring ejection pipes 41.

[0052] like Figure 7 、 Figure 9 As shown, the gas enters the rear tube cavity 362 in the first pipe 351 from the inner ring gas outlet pipe 51, and enters the two inner ring gas guide cavities 372 from the rear tube cavity 362, and finally enters the inner ring ejector pipe 41 from the inner ring gas guide cavity 372 through the corresponding first gas outlet 341.

[0053] The remaining undescribed parts are the same as those in the first embodiment and will not be repeated here.

[0054] The above embodiments are only preferred embodiments of the present invention, and other embodiments of the present invention are also possible.
