[0039] The utility model provides a burner with a simple assembly structure and high assembly efficiency.

[0040] See also Figures 1 to 5 In one embodiment of the present utility model, the burner 10 includes a frame 100 and a fire bar 200. The frame 100 includes a frame body 110 and a matching piece 120. The frame body 110 has a first opening 111, a second opening 112 and a side opening 113. The first opening 111 and the second opening 112 are arranged opposite to each other. The matching piece 120 includes a bottom frame plate 121 and a side frame plate 122. The bottom frame plate 121 and the side frame plate 122 are connected. The bottom frame plate 121 covers the first opening 111. The side frame plates 122 Covering the side opening 113, the frame body 110 and the matching piece 120 enclose a accommodating cavity, and the side frame plate 122 is provided with an air inlet hole 123; the fire bar 200 is arranged in the accommodating cavity, and the fire bar 200 has an injection channel 210, and the air outlet end of the injection channel 210 faces the second opening 112. The end of the fire bar 200 close to the first opening 111 is limited to the bottom frame plate 121, and the air inlet end of the injection channel 210 is limited to the side frame plate 122 and communicates with the air inlet hole 123.

[0041] It is understood that the frame 100 can be a hollow structure with one side open, and a receiving cavity is formed therein for accommodating the fire bar 200. The shape of the frame 100 can be set according to the specific structure of the fire bar 200, including but not limited to a square frame 100, a cylindrical frame 100, etc.

[0042] For example, in this embodiment, the frame 100 is a square (or rectangular) frame structure with an open top, and the frame 100 is adapted to the overall shape of a plurality of fire bars 200 arranged side by side. Specifically, the frame body 100 includes a frame body 110 and a matching piece 120. The matching piece 120 includes a bottom frame plate 121 and a side frame plate 122. The bottom frame plate 121 and the side frame plate 122 are connected. The frame body 110 is a semi-enclosed structure with a side opening 113 (for example, a U-shaped structure with three sides). The bottom opening of the frame body 110 is a first opening 111, the top opening of the frame body 110 is a second opening 112, and the opening at the side end of the frame body 110 is a side opening 113. The matching piece 120 covers the first opening 111 and the side opening 113 of the frame body 110, that is, the bottom frame plate 121 covers the first opening 111, and the side frame plate 122 covers the side opening 113, so that the frame body 110 and the matching piece 120 enclose and form an accommodating cavity for accommodating the fire bar 200. The bottom frame plate 121 and the side frame plates 122 are connected. The bottom frame plate 121 and the side frame plates 122 can be integrally formed. Of course, the bottom frame plate 121 and the side frame plates 122 can also be assembled using fasteners or snap-fit connections. By forming the frame body 110 and the mating parts 120 separately, it is convenient to first install the fire bar 200 on the mating parts 120, and then install the frame body 110 on the mating parts 120, thereby simplifying the assembly process of the burner 10. The frame body 110 and the mating parts 120 can be assembled using methods including, but not limited to, welding, fasteners, or snap-fit connections. The frame body 110 and the mating parts 120 can be made of sheet metal to ensure sufficient structural strength and heat resistance.

[0043] Furthermore, an ejection channel 210 is constructed within the fire bar 200. An air inlet communicating with the ejection channel 210 is provided at one end of the fire bar 200, near the side frame plate 122. This air inlet serves as the air inlet end of the ejection channel 210. The side frame plate 122 is provided with an air inlet hole 123 corresponding to and connected to the air inlet. An air outlet 240 communicating with the ejection channel 210 is provided at the upper end of the fire bar 200. This air outlet 240 serves as the air outlet end of the ejection channel 210. The air outlet end of the ejection channel 210 faces the second opening 112. In other words, the air outlet 240 of the fire bar 200 faces the top of the frame body 100. When multiple fire bars 200 are arranged side by side in the accommodating cavity, the air inlets of the multiple fire bars 200 are all arranged toward the side frame plate 122. Accordingly, multiple air inlet holes 123 can be provided on the side frame plate 122, and the multiple air inlet holes 123 are arranged in a one-to-one correspondence with the multiple fire bars 200. The burner 10 can also include a gas nozzle arranged corresponding to the air inlet, and an ignition needle installed on the side frame plate 122. The ignition needle is located at the top of the fire bar 200. When the burner 10 is in operation, the gas nozzle sprays gas from the air inlet into the introduction channel 210. At the same time, air can enter the introduction channel 210 from the air inlet. The gas and air are fully mixed in the introduction channel 210 and then transported to the air outlet 240 at the top of the fire bar 200. The mixed gas at the air outlet 240 is ignited by the ignition needle to achieve combustion.

[0044] Furthermore, the end of the fire bar 200 near the first opening 111 is restrained on the bottom frame plate 121, that is, the bottom frame plate 121 can restrain the fire bar 200. The specific restraining structure includes, but is not limited to, a latching hole structure, a latching slot structure, and a latching post. The air inlet end of the ejection channel 210 is restrained on the side frame plate 122 and communicates with the air inlet hole 123. That is, the side frame plate 122 can restrain the fire bar 200. The specific restraining structure includes, but is not limited to, a latching hole structure, a latching slot structure, and a latching post structure at the edge of the air inlet hole 123. Of course, when restraining the fire bar 200 for installation, a restraining structure such as, but not limited to, a latching hole structure, a latching slot structure, and a latching post structure can also be provided on the fire bar 200. That is to say, the fire bar 200, the bottom frame plate 121 and the side frame plate 122 can be respectively provided with a limiting structure. Of course, only the bottom frame plate 121 and the side frame plate 122 can be provided with a limiting structure, and the fire bar 200 can be adapted to the limiting structure.

[0045] When assembling the burner 10, first place the fitting 120. Then, position the end of the fire bar 200 closest to the first opening 111 on the bottom frame plate 121. Position the air intake end of the fire bar 200's ejection channel 210 on the side frame plate 122, ensuring that the fire bar 200 is stably mounted on the fitting 120. Once the fire bar 200 is securely mounted, the frame body 110 is then positioned around the fitting 120. For example, the fire bar 200 can be first assembled on the fitting 120 in the second orientation, ensuring an unobstructed view of the burner. The frame body 110 is then assembled on the fitting 120 in the second orientation. This allows all components to be assembled in the same pre-set orientation, eliminating the need to rotate the frame body 110, fitting 120, and fire bar 200. Of course, the frame body 110 can also be assembled on the fitting 120 from top to bottom, allowing for precise assembly as needed.

[0046] The burner 10 of the present invention includes a frame 100 and a fire bar 200. The frame 100 includes a frame body 110 and a matching piece 120. The matching piece 120 includes a bottom frame plate 121 and a side frame plate 122. The bottom frame plate 121 and the side frame plate 122 are connected. The side frame plate 122 is provided with an air inlet 123. The frame body 110 and the matching piece 120 are enclosed to form an accommodating cavity. The fire bar 200 is arranged in the accommodating cavity. The fire bar 200 has an injection channel 210. One end of the fire bar 200 close to the first opening 111 of the frame body 110 is limited to the bottom frame plate 121. The air inlet end of the injection channel 210 is limited to the side frame plate 122 and is connected to the inlet. The air holes 123 are connected. With such an arrangement, during assembly, it is only necessary to limit one end of the fire bar 200 to the bottom frame plate 121 and the air inlet end of the injection channel 210 of the fire bar 200 to the side frame plate 122 to achieve the positioning and installation of the fire bar 200, and then the frame body 110 is surrounded and arranged on the matching piece 120. The assembly structure of the burner 10 is simple and the installation sight is not obstructed. Moreover, the fire bar 200 and the frame body 110 can be installed on the matching piece 120 in the same assembly direction. The assembly process is simple and convenient, and no additional jig is required for positioning, which is conducive to realizing automated assembly and improving assembly efficiency. Compared to the prior art method of first using a jig to position the frame body 110, and then installing the fire bar 200 and the side panels on the frame body 110 in sequence before flipping the orientation, this solution does not require additional jigs to position the parts to be assembled. The entire assembly process does not require flipping the matching parts 120, the fire bar 200 and the frame body 110. The entire assembly process of the burner 10 is simple and convenient. When the burner 10 needs to be disassembled, it is only necessary to remove the frame body 110 and the fire bar 200 from the matching parts 120 in the same disassembly direction. The entire disassembly process is simple and convenient, and is easy to disassemble and repair. It can be seen that the technical solution of the present application can simplify the assembly structure of the burner 10, improve assembly efficiency, and also facilitate disassembly and maintenance.

[0047] See also Figures 1 to 4 In one embodiment, a plurality of fire bars 200 are arranged side by side in the accommodating cavity along the first direction, a first limiting portion 124 is provided on the bottom frame plate 121, and the bottom end of each fire bar 200 is respectively engaged with the first limiting portion 124.

[0048] It is understandable that multiple fire bars 200 are arranged side by side in the accommodating cavity along the first direction, which can increase the overall combustion area of the burner 10. Among them, the multiple fire bars 200 can be two, three, four or more, which is not specifically limited here. The specific structure of the first limiting portion 124 is not limited. For example, the bottom frame plate 121 is provided with multiple limiting holes or limiting grooves, etc., which only need to be able to limit the bottom end of the fire bar 200. By providing the first limiting portion 124 on the bottom frame plate 121, the positioning and installation of multiple fire bars 200 are facilitated, and the fire bars 200 are prevented from being installed tilted and affecting the assembly efficiency.

[0049] See also Figure 2 、 Figure 6 and Figure 7 In one embodiment, the first limiting portion 124 includes a first convex portion 1241 and a plurality of first limiting grooves 1242 arranged along the first direction, and the plurality of first limiting grooves 1242 are arranged in sequence on the first convex portion 1241. The first limiting grooves 1242 penetrate the first convex portion 1241 along the second direction, and the bottom end of each of the fire bars 200 is respectively engaged in the first limiting groove 1242 along the second direction, and the first direction intersects with the second direction.

[0050] It can be understood that the first limiting groove 1242 has an upwardly disposed notch, and the first limiting groove 1242 penetrates the first protrusion 1241 along the second direction, and the bottom end of the fire bar 200 is limitedly engaged in the first limiting groove 1242. During assembly, the fire bar 200 is arranged along the second direction and aligned with the first limiting groove 1242, and then the fire bar 200 is pushed to move along the second direction so that the bottom end of the fire bar 200 is engaged in the first limiting groove 1242. The fire bar 200 is then pushed along the second direction until it is limited on the side frame plate 122 and communicates with the air inlet 123. In this way, the bottom and side ends of the fire bar 200 are limited, so that the fire bar 200 can be stably installed on the mating component 120. The assembly is simple and convenient, and the installation line of sight is not obstructed. This is conducive to assembling multiple fire bars 200 separately along the second direction, thereby improving assembly efficiency.

[0051] See also Figure 6 and Figure 7In one embodiment, the width of the first limiting groove 1242 along the first direction tapers from the first protrusion 1241 toward the air inlet 123. This configuration allows the fire bar 200 to be positioned with its conductors when the bottom end of the fire bar 200 is engaged with the first limiting groove 1242 along the second direction. This allows the fire bar 200 to slide smoothly along the second direction. Furthermore, the fire bar 200 engaged with the first limiting groove 1242 is less likely to tilt or fall, thereby improving the installation stability of the fire bar 200 and facilitating automated assembly.

[0052] In one embodiment, a portion of the outer side surface of the bottom frame plate 121 is recessed toward the accommodating cavity to form the first protrusion 1241. This configuration makes the first protrusion 1241 easier to process and form, simplifies the structure of the bottom frame plate 121, and helps reduce manufacturing costs.

[0053] In one embodiment, the bottom frame plate 121 has a first side and a second side that are opposite to each other along the second direction, the second side being connected to the side frame plate 122, and the distance between the first protrusion 1241 and the first side is smaller than the distance between the first protrusion 1241 and the second side. With this arrangement, the first protrusion 1241 and the plurality of first limiting grooves 1242 thereon are relatively far from the side frame plate 122, that is, the first limiting portions 124 are relatively far from the side frame plate 122, so that the end of the fire bar 200 that is farther from the side frame plate 122 can be stably mounted on the bottom frame plate 121, and the end of the fire bar 200 that is closer to the side frame plate 122 can be stably mounted on the side frame plate 122. This allows both ends of the fire bar 200 to be stably mounted on the mating component 120, thereby improving the installation stability of the fire bar 200.

[0054] See also Figure 3 、 Figure 6 and Figure 7 In one embodiment, the side frame plate 122 is provided with a plurality of air inlet holes 123 spaced apart along the first direction near the bottom frame plate 121, and the edge of each air inlet hole 123 is provided with a second limiting portion 125 extending toward the inner side of the accommodating cavity, and the air inlet end of the ejection channel 210 of each fire bar 200 is respectively engaged with the second limiting portion 125.

[0055] It is understood that the second limiting portion 125 may be an annular limiting platform, or may be formed by multiple limiting platforms spaced circumferentially around the edge of the air inlet 123, and the specific details are not limited here. The air inlet end of the ejection channel 210 of the fire bar 200 can be mounted outside the second limiting portion 125, or the air inlet end of the ejection channel 210 of the fire bar 200 can be inserted into the second limiting portion 125. It is sufficient that the air inlet of the fire bar 200 is connected to the air inlet 123 on the side frame plate 122. This ensures that the fire bar 200 can be stably connected to the side frame plate 122. During assembly, the fire bars 200 are arranged along the second direction and aligned with the first limiting grooves 1242 and the second limiting portions 125. The fire bars 200 are then moved in the second direction so that the bottom ends of the fire bars 200 are locked in the first limiting grooves 1242. The fire bars 200 are then pushed in the second direction until they are locked and engaged with the second limiting portions 125 and communicate with the air inlet holes 123. This effectively limits the bottom and side ends of the fire bars 200, allowing the fire bars 200 to be stably installed on the mating component 120. Assembly is simple and convenient, and the installation line of sight is unobstructed, which facilitates the assembly of multiple fire bars 200 in the second direction, thereby improving assembly efficiency. The number of air inlet holes 123 and second limiting portions 125 is the same as the number of fire bars 200. By providing multiple second limiting portions 125 on the side frame plate 122, the positioning and installation of multiple fire bars 200 are facilitated, preventing the fire bars 200 from being tilted during installation and affecting assembly efficiency.

[0056] See also Figure 3 、 Figure 6 and Figure 7 In one embodiment, a third stopper 126 is provided on the side frame plate 122 away from the bottom frame plate 121. The end of each fire bar 200 proximate the side opening 113 is engaged with the third stopper 126. It is understood that the specific structure of the third stopper 126 is not limited. For example, multiple stopper holes or stopper grooves may be provided on the side frame plate 122, so long as they can engage the side ends of the fire bar 200. Providing the third stopper 126 on the side frame plate 122 facilitates the positioning and installation of multiple fire bars 200, preventing tilted installation of the fire bars 200 and affecting assembly efficiency.

[0057] See also Figure 6 and Figure 7 In one embodiment, the third limiting portion 126 includes a first inclined plate 1261 and a plurality of second limiting grooves 1262 arranged along the first direction, and the plurality of second limiting grooves 1262 are arranged in sequence on the first inclined plate 1261, and the notches of the second limiting grooves 1262 face the second opening 112, and the side ends of each fire bar 200 close to the side opening 113 are respectively clamped in the second limiting grooves 1262 along the second direction.

[0058] It can be understood that the first inclined plate 1261 is arranged at an angle relative to the bottom frame plate 121. Specifically, the first inclined plate 1261 can be extended obliquely upward away from the bottom frame plate 121, so as to facilitate the side end of the fire bar 200 close to the side frame plate 122 to be limited and engaged in the second limiting groove 1262. When assembling, the fire bar 200 is arranged in the second direction and aligned with the first limiting groove 1242, the second limiting part 125 and the second limiting groove 1262, and then the fire bar 200 is pushed to move in the second direction so that the bottom end of the fire bar 200 is clamped in the first limiting groove 1242, and then the fire bar 200 is pushed in the second direction until it is clamped with the second limiting part 125 and connected to the air inlet 123, and the side end of the fire bar 200 is clamped in the second limiting groove 1262, so that the bottom and side ends of the fire bar 200 are limited. The first limiting groove 1242, the second limiting part 125 and the second limiting groove 1262 on the matching part 120 all limit the fire bar 200, ensuring that the fire bar 200 can be stably installed on the matching part 120. The assembly of the fire bar 200 is simple and convenient, and the installation line of sight is not obstructed, which is conducive to assembling multiple fire bars 200 separately along the second direction, thereby improving assembly efficiency.

[0059] See also Figures 2 to 4 In one embodiment, the fire bar 200 is provided with a relief notch 220 at a bottom corner near the side frame plate 122 to accommodate a portion of the side frame plate 122. A notch is provided on the side edge of the fire bar 200 near the first inclined plate 1261 to form a positioning edge 230. The positioning edge 230 is located above the relief notch 220 and is inserted into the second limiting groove 1262. It is understood that the shape of the relief notch 220 matches the shape of the lower end of the side frame plate 122. Thus, when the fire bar 200 is installed on the mating component 120, the lower end of the side frame plate 122 is accommodated in the relief notch 220, making the mating structure between the side frame plate 122 and the fire bar 200 compact. Furthermore, the relief notch 220 can pre-position the fire bar 200, improving the assembly efficiency and stability of the fire bar 200.

[0060] Furthermore, a positioning edge 230 is provided on the fire bar 200, and the shape of the positioning edge 230 is adapted to the shape of the second limiting groove 1262. When assembling the fire bar 200, the positioning switch is inserted into the second limiting groove 1262 along the second direction, further improving the stability of the fire bar 200 assembled on the mating part 120.

[0061] See also Figure 6In one embodiment, the side frame plate 122 includes a first plate body 127, a second plate body 128, a first inclined plate 1261 and a third plate body 129 connected in sequence, the first plate body 127 is connected to the bottom frame plate 121, the second plate body 128 extends toward a side away from the bottom frame plate 121 and is bent at the connection with the first plate body 127, the first inclined plate 1261 extends obliquely upward away from the second plate body 128 and is bent at the connection with the second plate body 128, the third plate body 129 extends upward away from the first inclined plate 1261 and is bent at the connection with the first inclined plate 1261, and the air inlet 123 is provided on the first plate body 127.

[0062] It can be understood that the bending angle between the first plate 127 and the second plate 128 is not limited, such as an acute angle, a right angle, an obtuse angle, etc. In the present embodiment, the bending angle between the first plate 127 and the second plate 128 is 90 degrees; the bending angle between the second plate 128 and the first inclined plate 1261 is not limited, such as an acute angle, a right angle, an obtuse angle, etc. In the present embodiment, the bending angle between the second plate 128 and the first inclined plate 1261 is an obtuse angle, such as 120 degrees, 135 degrees, or 150 degrees, etc., specifically 135 degrees; the bending angle between the first inclined plate 1261 and the third plate 129 is not limited, such as an acute angle, a right angle, an obtuse angle, etc. In the present embodiment, the bending angle between the first inclined plate 1261 and the third plate 129 is an obtuse angle, such as 120 degrees, 135 degrees, or 150 degrees, etc., specifically 135 degrees. Among them, the air inlet 123 is arranged on the first plate body 127, and the second limiting groove 1262 is arranged on the first inclined plate 1261. The first plate body 127 and the first inclined plate 1261 are spaced apart, so that the second limiting portion 125 and the second limiting groove 1262 on the edge of the air inlet 123 are spaced apart on the side frame plate 122. There is a certain distance between the second limiting portion 125 and the second limiting groove 1262. The second limiting portion 125 and the second limiting groove 1262 both limit the side end of the fire bar 200, ensuring that the fire bar 200 can be stably installed on the side frame plate 122. The assembly of the side end of the fire bar 200 is simple and convenient, and the installation line of sight is not obstructed, which is conducive to realizing automated assembly and improving assembly efficiency.

[0063] In one embodiment, the edge of each air inlet 123 is provided with a second stopper 125 that engages with the corresponding fire bar 200. The projections of the first stopper 124, the second stopper 125, and the third stopper 126 on the mating component 120 corresponding to each fire bar 200 along the second direction onto the frame body 110 are arranged in a straight line. This arrangement allows the fire bar 200 to be positioned by the first stopper 124, the second stopper 125, and the third stopper 126, which enhance the stability of the fire bar 200 when mounted on the mating component 120. Furthermore, the straight line connecting the projections of the three stoppers on the frame body 110 ensures an unobstructed view of the fire bar 200 along the second direction, preventing the fire bar 200 from tipping or tilting when mounted on the mating component 120 along the second direction, thus facilitating automated assembly.

[0064] In one embodiment, the bottom frame plate 121 and the side frame plates 122 are integrally formed. This configuration simplifies the structure of the mating component 120 and ensures sufficient structural strength. Optionally, the bottom frame plate 121 and the side frame plates 122 are integrally formed from sheet metal, ensuring that the mating component 120 has sufficient heat resistance.

[0065] See also Figure 4 and Figure 5 In one embodiment, the frame body 110 is provided with a fourth stopper 114, and the end of the fire bar 200 away from the side opening 113 is locked in position with the fourth stopper 114. It is understood that the specific structure of the fourth stopper 114 is not limited. For example, the frame body 110 may be provided with multiple stopper holes or stopper grooves, which only need to be able to lock the end of the fire bar 200 away from the side opening 113. Providing the fourth stopper 114 on the frame body 110 improves the stability of the fire bar 200 installed in the frame body 100.

[0066] In one embodiment, the fourth limiting portion 114 includes a first folded edge 1141 arranged along the first direction, a second folded edge 1142 connected to the first folded edge 1141, a third limiting groove 1143 provided on the first folded edge 1141, and a fourth limiting groove 1144 provided on the second folded edge 1142. The third limiting groove 1143 and the fourth limiting groove 1144 are connected. The third limiting groove 1143 passes through the first folded edge 1141 along the second direction. The notch of the fourth limiting groove 1144 faces the side opening 113. The side end of the fire bar 200 away from the side opening 113 is clamped in the third limiting groove 1143 and the fourth limiting groove 1144, and the first direction intersects with the second direction.

[0067] It can be understood that the frame body 110 may include an outer frame and an inner frame. The inner frame is arranged inside the outer frame and is detachably connected to the outer shell. The fourth limiting portion 114 is arranged on the inner frame. The inner frame is smaller in volume than the outer frame, which facilitates the processing of the second limiting portion 125 on the inner shell, thereby simplifying the molding process of the frame body 110.

[0068] Furthermore, the lower edge of the inner frame is provided with a flange, and the flange, the first folded edge 1141 and the second folded edge 1142 are connected in sequence. The flange extends toward the inner side of the accommodating cavity, the first folded edge 1141 extends toward one side of the bottom frame plate 121, and the second folded edge 1142 extends toward the inner side of the accommodating cavity. A third limiting groove 1143 is provided on the first folding edge 1141 and is arranged to pass through along the second direction. A fourth limiting groove 1144 is provided on the second folding edge 1142. The third limiting groove 1143 and the fourth limiting groove 1144 are connected. The fourth limiting groove 1144 passes through the second folding edge 1142 along the direction from the first opening 111 to the second opening 112, and the notch of the fourth limiting groove 1144 faces the side opening 113. With such an arrangement, when assembling the frame body 110, the fourth limiting groove 1144 and the third limiting groove 1143 can be limit-engaged with the end of the fire bar 200 away from the side opening 113, thereby further improving the stability of the fire bar 200 installed in the frame body 100.

[0069] During assembly, first assemble the fire bar 200 on the matching piece 120, specifically arrange the fire bar 200 along the second direction and align it with the first limiting groove 1242, the second limiting part 125 and the second limiting groove 1262, then push the fire bar 200 to move along the second direction so that the bottom end of the fire bar 200 is clamped in the first limiting groove 1242, and then push the fire bar 200 along the second direction until it is clamped with the second limiting part 125 and connected to the air inlet 123, and the side end of the fire bar 200 is clamped in the second limiting groove 1262, so that the fire bar 200 is stably installed on the matching piece 120. After the multiple fire bars 200 are assembled on the mating member 120, the frame body 110 is then assembled on the mating member 120. The frame body 110 is locked with the end of the fire bar 200 away from the side opening 113 via the fourth limiting portion 114, so that the multiple fire bars 200 are accommodated in the accommodating cavity. The connection methods of the frame body 110 and the mating member 120 include, but are not limited to, one or more of fastener connection, snap connection, etc. The specific process of assembling the frame body 110 on the mating member 120 is as follows: the frame body 110 is installed on the mating member 120 along the second direction or from top to bottom, and the end of the fire bar 200 away from the side opening 113 is sequentially locked in the fourth limiting groove 1144 and the third limiting groove 1143 to further limit the position of the fire bar 200, thereby ensuring the stability of the fire bar 200 installed in the frame body 100.
