[0034] This utility model proposes a burner for use in gas heating equipment, such as gas water heaters, gas wall-hung boilers, or gas boilers, aiming to solve the problem of false alarms caused by the aforementioned fuses. The following description uses a gas water heater as an example. For ease of understanding and explanation, the following is attached to the specification of this utility model. Figures 1 to 3 In the diagram, the solid arrow indicates a slot or hole.

[0035] In an embodiment of this invention, the burner 10 has a combustion body 100. The combustion body 100 includes a combustion frame 110, which encloses a combustion chamber. The combustion chamber is the area in the burner 10 that burns a mixture of gas and air; this is a crucial area in a gas water heater, its main function being to provide a closed, safe space for thorough mixing and efficient combustion of the gas and air, and to transfer the heat generated by combustion to a heat exchanger for heating water. In some embodiments, the combustion body 100 also includes components such as a burner head, an ignition device, a gas valve, an air mixer, and nozzles.

[0036] To prevent unnecessary danger caused by flame overflow due to combustion chamber damage, a high-temperature fuse 20 is usually installed around the top of the burner body 100. In existing gas water heaters, the fuse 20 is usually fixed by using plastic cable ties to wrap around the top of the burner body 100. However, using plastic cable ties to fix the fuse 20 is difficult to control in terms of manufacturing process and installation. The fuse may be too close to the burner body 100, causing false alarms. After long-term use, the plastic cable ties age, and the fuse 20 falls off and fails. Later maintenance requires cutting the cable ties to access other components inside the burner body 100, which is a complicated operation.

[0037] In order to solve at least one of the problems caused by using plastic cable ties to fix the fuse 20, in this embodiment, a fixing member 200 is provided on the outer periphery of the combustion body 100, and the fixing member 200 and the combustion body 100 form a mounting groove 11 for installing the fuse 20.

[0038] The fastener 200 can be installed on the combustion body 100, for example, by plugging, snapping, threading, or welding; or it can be integrally formed with the combustion body 100. Preferably, the fastener 200 is integrally formed with the combustion body 100. Thus, since the fastener 200 is directly installed on the outer periphery of the combustion body 100, the fuse 20 can be directly installed into the mounting groove 11, thereby simplifying the installation process of the fuse 20.

[0039] The technical solution of this utility model is to provide a fixing member 200 on the outer periphery of the combustion body, and the fixing member 200 and the combustion chamber form an installation groove 11 for installing the fuse 20, so that when installing the fuse 20, it can be directly installed into the installation groove 11, thereby simplifying the installation process of the fuse 20.

[0040] The material of the fastener 200 is generally high temperature resistant, such as metal or high temperature glass fiber. In the embodiment where the fastener 200 is integrally formed with the combustion body 100, the fastener 200 is a metal part, generally a sheet metal part. Thus, the technical solution of this embodiment can solve the problems that the plastic cable tie may melt and stick tightly to the combustion body 100, causing false alarms, and that after long-term use, the plastic cable tie ages and the fuse 20 falls off and fails.

[0041] It should be understood that, in this embodiment, the aforementioned fuse 20 refers to a high-temperature fuse 20, which consists of a temperature-sensitive metal element (typically a low-melting-point alloy) and a support structure that holds it in place. This alloy melts at a specific high temperature. Once the high-temperature fuse 20 activates, the electrical components of the gas water heater are quickly disconnected, stopping the power supply and thus halting the gas supply and combustion process. This process effectively prevents flame overflow from further igniting a fire or other hazards.

[0042] In one embodiment, the combustion body 100 includes a combustion frame 110 forming a combustion chamber and a mounting platform 120 disposed on the top surface of the combustion frame 110; the fixing member 200 is disposed on the mounting platform 120 and integrally formed with the mounting platform 120; the combustion frame 110, the mounting platform 120 and the fixing member 200 surround to form the mounting groove 11.

[0043] The combustion frame 110 is usually formed from sheet metal parts through processes such as bending, shearing or stamping. In this embodiment, the mounting platform 120 is integrally formed with the combustion frame 110. That is to say, the mounting platform 120 can be a sheet metal part constituting the combustion frame 110, which is formed by bending to form a flange 240 through bending and other technical means. This manufacturing process is simple and has good sealing performance.

[0044] In this embodiment, since the fastener 200 and the mounting platform 120 are integrally formed, the installation of the fuse 20 does not require additional components or complex fixing devices, simplifying the installation steps and saving time and labor costs. Secondly, the integral forming of the fastener 200 and the mounting platform 120 reduces the risk of gaps or loosening between connecting parts, making the fuse 20 more secure in the mounting groove 11 and preventing loosening or detachment due to factors such as vibration or thermal expansion. In addition, by integrally forming the fastener 200 and the mounting platform 120, the need for screws or other external fasteners is reduced, thereby reducing the risk of aging, damage, or detachment of these components and improving the overall system reliability.

[0045] To better secure fuse 20, such as Figure 1 As shown, there are multiple fasteners 200, which are arranged at intervals along the circumference of the combustion chamber. The number of fasteners 200 includes, but is not limited to, two, three, four, five, six, or more than six; examples will not be provided here.

[0046] Furthermore, the combustion frame 110 includes a back plate, a front plate, and two side plates. The back plate and the front plate are arranged opposite to each other, and the two side plates are connected to the two sides of the back plate and the front plate. At least one of the fixing members 200 is provided on the periphery of the back plate, the front plate, and the two side plates respectively.

[0047] In this embodiment, fasteners 200 are respectively provided on the back plate, front plate, and side plate perimeters, providing multi-point support to make the fuse 20 more securely fixed, reducing the risk of loosening or falling off due to vibration or thermal expansion. The multi-point fixing design makes the force more even, avoiding stress concentration that may be caused by single-point fixing, reducing wear on the fuse 20 and fasteners 200, thereby extending their service life. Multiple fasteners 200 provide more installation position options, facilitating flexible adjustment under different environmental and spatial conditions, ensuring the convenience and adaptability of fuse 20 installation. Multi-point fixing can make the contact between the fuse 20 and the combustion frame 110 tighter, which helps to evenly distribute heat and effectively dissipate heat, improving the thermal stability and safety of the fuse 20 and the entire combustion system. In addition, multi-point fixing also enhances the structural strength of the combustion frame 110 itself, and the more stable installation reduces the risk of failure caused by loosening or displacement of the fuse 20 during operation, improving the safety of the entire gas water heater.

[0048] In one embodiment, the fastener 200 includes a first fixing plate 210 and a second fixing plate 220. The first fixing plate 210 is connected to the combustion body 100, and the second fixing plate 220 and the first fixing plate 210 are bendable to open or close the mounting slot 11.

[0049] The second fixing plate 220 and the first fixing plate 210 are bendable, meaning that the metal has the unique ductility to deform without breaking when subjected to tension or pressure. This allows the installation slot 11 to be opened or closed by bending or other operations at the connection between the second fixing plate 220 and the first fixing plate 210 when the fuse 20 needs to be replaced.

[0050] In this embodiment, since the first fixing plate 210 and the second fixing plate 220 can be bent and connected, opening or closing the mounting slot 11 becomes very convenient. This also allows for quick installation and removal of the fuse 20, reducing maintenance time and labor costs. Furthermore, the fixing member 200 can securely hold the fuse 20 when closed, reducing the possibility of accidental loosening or poor contact. In addition, the technical solution of this embodiment, by adjusting the bending angle of the fixing member 200, can adapt to fixing fuses 20 of different sizes or shapes.

[0051] Furthermore, in order to better enclose the fuse 20, the fastener 200 also includes a third fixing plate 230, which is located on the side of the second fixing plate 220 away from the first fixing plate 210, and the third fixing plate 230 and the second fixing plate 220 can be bent and connected.

[0052] Normally, the fuse 20 is cylindrical. In this embodiment, by adding an extra bend, the mounting groove 11 formed between the fixing member 200 and the combustion body 100 can more closely enclose the fuse 20. In some embodiments, the fixing member 200 may also include a fourth fixing plate, a fifth fixing plate, etc., and the first fixing plate 210, the second fixing plate 220, the third fixing plate 230, the fourth fixing plate, and the fifth fixing plate can be bent and connected in sequence.

[0053] like Figure 2 and Figure 3As shown, during actual installation, the second fixing plate 220 is first bent relative to the first fixing plate 210. Then, the fuse 20 is placed below the fixing member 200. Finally, the third fixing plate 230 is bent relative to the second fixing plate 220, so that the fixing member 200 and the combustion body 100 together form the mounting groove 11, which encloses the fuse 20. When it is necessary to remove the fuse 20, the third fixing plate 230 is bent in the opposite direction relative to the second fixing plate 220. If the bending angle is large enough, the fuse 20 can be removed. Furthermore, the second fixing plate 220 can be bent in the opposite direction relative to the first fixing plate 210, so that the opening of the mounting groove 11 will be larger, making it easier to remove the fuse 20.

[0054] In one embodiment, in order to reduce the bending difficulty of the fastener 200, a hole is provided at the connection between the first fixing plate 210 and the second fixing plate 220, and the hole extends along the thickness direction of the fastener 200; wherein, the hole can be a blind hole or a through hole 201; preferably, the hole is a through hole 201.

[0055] Thus, in this embodiment, the hole design makes the material thinner around the hole, and the thinner part is more likely to undergo plastic deformation during bending. Since the material thickness around the hole is reduced, the force required for bending is less than that for material of uniform thickness, thereby reducing the difficulty of bending.

[0056] In another embodiment, in order to reduce the bending difficulty of the fastener 200, a hole is provided at the connection between the second fixing plate 220 and the third fixing plate 230; the hole extends along the thickness direction of the fastener 200; wherein, the hole can be a blind hole or a through hole 201; preferably, the hole is a through hole 201.

[0057] The holes located at the connection between the first fixing plate 210 and the second fixing plate 220, and at the connection between the second fixing plate 220 and the third fixing plate 230, can be the same. In other words, a large rectangular hole is provided in the middle of the fixing member 200. Of course, there can also be multiple holes, with multiple through holes 201 arranged at intervals along the length direction of the fixing member 200; or, multiple through holes 201 arranged at intervals along the width direction of the fixing member 200. Any method that can reduce the bending difficulty of the fixing member 200 is acceptable, and no specific limitation is made here.

[0058] The hole can be a regular shape such as circular, elliptical, square, or rectangular, or it can be other irregular shapes. Preferably, the hole is elongated and extends along the width direction of the fixing member 200.

[0059] Based on the previous embodiment, in the width direction of the fastener 200, the width of the outer frame forming the hole is not less than 2.0 mm and not more than 3.0 mm; exemplaryly, the width of the outer frame of the hole includes, but is not limited to, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3.0 mm. Wherein, the width of the outer frame of the hole is as follows... Figure 2 As shown in b in the figure.

[0060] In another embodiment, to prevent scratching of the wiring harness of the fuse 20 during installation and transportation, the fastener 200 is provided with a flange 240, which is located on the side of the fastener 200 opposite to the mounting groove 11. Preferably, the flange 240 is an overlapping edge.

[0061] Based on the previous embodiment, to reduce the bending difficulty of the fastener 200, the flange 240 has a notch 202 at the connection between the first fixing plate 210 and the second fixing plate 220. During the bending process, the bending torque is proportional to the thickness and width of the material. The notch 202 at the connection between the first fixing plate 210 and the second fixing plate 220 of the flange 240 reduces the effective thickness of the cross-section at the bending point; it reduces the bending torque required, thereby reducing the bending difficulty.

[0062] Furthermore, based on the two embodiments described above, the flange 240 is provided with a notch 202 at the connection between the second fixing plate 220 and the third fixing plate 230.

[0063] This utility model also proposes a gas heating device, which includes a burner 10. The specific structure of the burner 10 is as described in the above embodiments. Since this gas heating device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The gas heating device can be a gas water heater, a gas wall-hung boiler, or a gas boiler, etc.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
