[0029] Please refer to Figures 1 to 6 The utility model provides a burner bracket, including a bracket body 503, a bottom shell mounting plate 501, a mounting plate 51 and a fixing plate 52. The bracket body 503 has an ejector tube mounting position 504 for mounting an ejector tube. The bottom shell mounting plate 501 is bent relative to the bracket body and extends downward (see attached Figure 1 (To be understood), the mounting plate 51 extends downward relative to the bracket body 503. The mounting plate 51 provided by the present invention can be a part of the bracket body 503 that is punched and bent downward, or it can be an independent mounting plate 51, which is then fixed to the bracket body 503 by, for example, welding. The mounting plate 51 and the fixing plate 52 are detachably connected. The detachability referred to in this embodiment can be partial detachability (for example, one end is hinged and the other end is detachable), or the fixing plate 52 can be completely removed. When the fixing plate 52 and the mounting plate 51 are fixed, an installation space for installing the ignition needle 701 and / or the thermocouple 702 is formed between the fixing plate 52 and the mounting plate 51, so that the ignition needle 701 and / or the thermocouple 702 can be installed in the space.

[0030] The burner bracket provided by the present invention has a mounting plate 51 extending downward relative to the bracket body 503. The mounting plate is extended downward, so that the ignition needle and the thermocouple can be installed from the side of the burner bracket. Compared with the installation method from the bottom in the prior art, it has a larger operating space and is more convenient to disassemble and assemble. The thermocouple and ignition needle can be replaced without disassembling the burner, which is beneficial to after-sales maintenance.

[0031] refer to Figure 2 In a preferred embodiment, the mounting plate is a portion of the bracket body. This portion is formed by stamping and bending downward to form the mounting plate 51. The mounting plate 51 has a first mounting groove 511 with a side opening. When the fixing plate 52 is opened relative to the mounting plate 51, the ignition needle and / or thermocouple is installed from the side opening of the first mounting groove 511. When the mounting plate 51 and the fixing plate 52 are locked and fixed, the side opening of the first mounting groove 511 is closed by the fixing plate 52, and the ignition needle 701 and / or thermocouple 702 are installed in the formed installation space. This method of obtaining the mounting plate by stamping the bracket body can save parts and improve installation efficiency. It can also further realize the disassembly and assembly of the thermocouple and / or ignition needle from the side of the burner, making after-sales maintenance more convenient.

[0032] refer to Figure 1-3 In a preferred embodiment, the fixing plate 52 has a second mounting groove 521 with a side opening. When the mounting plate 51 and the fixing plate 52 are fixed, the openings of the first mounting groove 511 and the second mounting groove 521 are opposite to each other, and the first mounting groove 511 and the second mounting groove 521 form an installation space.

[0033] refer to Figure 1-3 In a preferred embodiment, one end of the fixing plate 52 is hinged to the mounting plate 51, while the other end can be detached or fixed relative to the mounting plate 51, thereby opening or closing the installation space and enabling installation of the thermocouple 701 and / or ignition needle 702. To remove or install the thermocouple and / or ignition needle, only one end of the fixing plate 52 needs to be opened, improving the convenience of after-sales maintenance.

[0034] refer to Figure 1-3 In a preferred embodiment, one end of the fixing plate 52 is hinged to the mounting plate 51, and the other end has a first screw hole 522 that passes through the fixing plate 52. The mounting plate 51 has a second screw hole 512 that matches the first screw hole 522, and the second screw hole 512 passes through the mounting plate 51. The fixing plate 52 can be opened and closed relative to the mounting plate 51 by passing screws through the first screw hole 522 and the second screw hole 512. In the burner bracket provided in this embodiment, one end of the fixing plate 52 is hinged to the mounting plate 51. During maintenance, it is only necessary to unscrew the screws from the side and loosen the screws from the first screw hole 522 and the second screw hole 512 to achieve disassembly and assembly of the thermocouple and / or ignition needle. This is very convenient and quick and can be operated with one hand.

[0035] refer to Figure 1-2 In a preferred embodiment, the mounting plate 51 is formed by stamping a portion of the bracket body 503 that is not at the edge and then bending it downward, thereby forming an operation window on the bracket body 503. This structure allows the mounting plate 51 to be stamped directly from the bracket body 503, saving parts. The formed operation window allows the thermocouple and / or ignition needle to extend through the operation window, facilitating installation and removal. The operation window also facilitates observation during assembly and disassembly. Furthermore, this structure for forming the operation window allows the window to be surrounded by the material of the bracket body 503, which improves the rigidity and stability of the overall structure and extends its service life.

[0036] In another preferred embodiment (not shown), the mounting plate 51 is formed by bending a portion of the edge of the bracket body 503 downward, and the mounting plate 51 is connected to the side of the bracket body 503. In this structure, the edge of the bracket body 503 is bent directly downward without forming a window, and the operation of the mounting plate 51 is not blocked, making assembly and disassembly easier.

[0037] refer to Figure 1-4In a preferred embodiment, one end of the fixing plate 52 has a bent plug 523, and one end of the mounting plate 51 has an opening 513. The thickness of the bent plug 523 in its natural state is L1, and the width of the opening is L2, L1>L2. The bent plug 523 can be naturally confined in the opening 513. The thickness of the bent plug 523 can be compressed under the action of an external force, so that the bent plug can be inserted into or pulled out of the opening 513. This structure allows the fixing plate 52 to be replaced and facilitates after-sales maintenance. During installation, the bent plug 523 is pinched and compressed by hand, and then inserted into the opening 513. The bent plug 523 can be naturally confined in the opening 513, achieving the effect of one end being hinged. When disassembling the thermocouple and / or ignition needle, only the other end needs to be removed. Because the fixed plate 52 is hinged and limited at this end, it will not fall out, making disassembly and assembly easier and more convenient for maintenance.

[0038] refer to Figure 1-4 In a preferred embodiment, the other end of the fixing plate 52 has a first screw hole 522, and the other end of the mounting plate 51 has a second screw hole 512. The mounting plate 51 and the fixing plate 52 are detachably fixed by bolts passing through the first screw hole 522 and the second screw hole 512.

[0039] refer to Figure 1-2 In a preferred embodiment, the mounting plate 51 and the bracket body 503 are perpendicular to each other, so that the assembly and disassembly operation can be performed from the side. The perpendicularity referred to in this embodiment is not an absolute 90 degree, and an error of ±5 degrees is allowed.

[0040] refer to Figure 1-2 In a preferred embodiment, both the fixing plate 52 and the mounting plate 51 have retaining holes 500 where the mounting space is formed. The ignition needle and thermocouple are provided with retaining blocks that snap into the retaining holes. This prevents the thermocouple and / or ignition needle from moving loosely during side assembly and disassembly.

[0041] In a preferred embodiment, the utility model also provides a burner, including the burner head bracket mentioned in any of the above embodiments, an ignition needle 702 and a thermocouple 701 are installed in the installation space of the burner head bracket, an inner ejector tube 20a and an outer ejector tube 20b are installed in the ejector tube installation position 504, an ignition divider 40 is connected above the ejector tube, and an outer ring fire cover 90 is connected above the ignition divider 40.

[0042] In a preferred embodiment, the ejector tube includes an ejector tube body 201 and a sleeve 202 in sequence along the direction of gas flow. The wall thickness of the sleeve 202 is greater than the wall thickness of the ejector tube body 201. The ejector tube installation position has a flange structure 502 that is flipped toward the ejector tube body. The front end of the sleeve 202 is inserted into the flange hole formed by the flange structure 502, and the rear end of the sleeve 202 is connected to the ignition distributor.

[0043] The present invention is also equipped with a relatively thick sleeve 202. Because the sleeve 202 end face has a relatively thick wall, the sleeve 202 and the ignition divider 40 can be sealed by the end face, which better ensures that the sleeve 202 and the ignition divider 40 are not prone to air leakage. At the same time, because the present invention adopts a sleeve 202 with a relatively thick wall, the length of the sleeve 202 extending out of the fixed bracket 50 can be shortened, which can also solve the problem of the difficulty in taking and placing the ignition divider, and avoid the occurrence of fire leakage and safety accidents if the ignition divider is not put in place. The ignition divider has a simple structure, is sealed with the end face of the burner base, is not prone to air leakage, is easy to take and place, and greatly improves the user experience and safety performance. Through the fixed installation method of the flange structure 502 and the sleeve 202, air leakage can be further avoided.
