[0037] According to an embodiment of the present utility model, a burner assembly 100 is provided, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a stove plate 10 and a nozzle holder 20. The upper and lower sides of the stove plate 10 can be respectively installed with an ignition divider and a gas nozzle 210. The gas nozzle 210 is installed and fixed on the nozzle holder 20. The nozzle holder 20 is connected to the stove plate 10 through a connecting piece. The gas nozzle 210 sprays gas toward the stove plate 10. The gas mixes with air near the nozzle holder 20 to form a mixed gas. The mixed gas can be fully burned after entering the ignition divider.

[0038] In this embodiment, the stove plate 10 is provided with a first connection hole 11, and the nozzle holder 20 is provided with a second connection hole 201. After aligning the first connection hole 11 with the second connection hole 201, the nozzle holder 20 can be connected to the stove plate 10 by using a connecting member that passes through the first connection hole 11 and the second connection hole 201 in sequence. The connecting member includes but is not limited to bolts, nuts, screws, and pins.

[0039] Furthermore, the stove plate 10 is provided with a first limiting structure, and the nozzle holder 20 is provided with a second limiting structure. When the first limiting structure cooperates with the second limiting structure, the relative position of the nozzle holder 20 and the stove plate 10 can be limited, and the first connecting hole 11 and the second connecting hole 201 can be aligned to facilitate the passage of the connecting piece, thereby connecting the nozzle holder 20 to the stove plate 10.

[0040] Understandably, the nozzle holder 20 and the stove plate 10 are positioned by the cooperation of the first limiting structure and the second limiting structure, so that the first connection hole 11 is aligned with the second connection hole 201, so that it is convenient for the operator to insert the connecting piece into the first connection hole 11 and the second connection hole 201 in sequence, and then connect the nozzle holder 20 with the stove plate 10. It should be noted that the technical solution proposed by the utility model uses the first limiting structure and the second limiting structure to assist the stove plate 10 and the nozzle holder 20 in aligning, and does not require the operator to manually align, which can improve assembly efficiency and reduce installation costs.

[0041] The cooperation between the first limiting structure and the second limiting structure means that the first limiting structure and the second limiting structure are connected to or offset against each other.

[0042] It is understandable that the first limiting structure and the second limiting structure can be set to different structural forms, as long as the first limiting structure and the second limiting structure can define the relative position of the nozzle holder 20 and the stove plate 10 when they cooperate with each other, and align the first connecting hole 11 with the second connecting hole 201.

[0043] In some embodiments, one of the first limiting structure and the second limiting structure is configured as a protruding structure (not shown in the figure), and the other of the two is configured as a groove or a through hole (not shown in the figure) that is plugged into and matched with the protruding structure. The protruding structure can be configured as a columnar or block-shaped structure, and the contour of the groove or the through hole matches the contour of the protruding structure, and the protruding structure protrudes along a first direction. For example, when the protruding structure is provided on the stove plate 10, the protruding structure protrudes from the stove plate 10 toward the nozzle seat 20 along the first direction. When the protruding structure is provided on the nozzle seat 20, the protruding structure protrudes from the nozzle seat 20 toward the stove plate 10 along the first direction. The first direction is parallel to the through direction of the first connecting hole 11 and the second connecting hole 201. It can be understood that when the protruding structure is inserted into the groove or the through hole, the nozzle holder 20 and the stove plate 10 can be limited in a direction perpendicular to the first direction to prevent the nozzle holder 20 and the stove plate 10 from moving relative to each other in a direction perpendicular to the first direction, so as to achieve the alignment of the first connecting hole 11 and the second connecting hole 201 and maintain the aligned state unchanged, so as to facilitate the operator to insert the connecting parts into the first connecting hole 11 and the second connecting hole 201 in sequence, and then connect the nozzle holder 20 to the stove plate 10.

[0044] In other embodiments, the first limiting structure can be configured as a protrusion (not shown in the figure), and the second limiting structure can be configured as a groove (not shown in the figure) provided at the edge of the nozzle seat 20, and the limiting of the stove plate 10 and the nozzle seat 20 is achieved by abutting the groove on the edge of the nozzle seat 20 against the protrusion.

[0045] In some embodiments, please combine Figure 4 and Figure 5As shown, one of the first limiting structure and the second limiting structure is configured as a buckle 1021, and the other of the two is configured as a clamping hole 1011 that is clamped with the buckle 1021. During the installation of the nozzle holder 20, the buckle 1021 can be first clamped with the clamping hole 1011 to fix the nozzle holder 20 on the stove plate 10 for pre-installation, and then the connecting piece can be used to pass through the first connecting hole 11 and the second connecting hole 201 in sequence, so as to connect the nozzle holder 20 to the stove plate 10.

[0046] Further, the nozzle holder 20 includes a main body 21 and a connecting plate 22, the connecting plate 22 is connected to the main body 21, the connecting plate 22 is used to connect to the stove plate 10, the second connecting hole 201 is provided on the connecting plate 22, the connecting plate 22 is provided with a buckle 1021, the stove plate 10 is provided with a clamping hole 1011, the connecting plate 22 is plate-shaped, when the buckle 1021 is engaged with the clamping hole 1011, the plate surface of the connecting plate 22 is against the plate surface of the stove plate 10, and the connecting plate 22 is fixedly installed on the stove plate 10 by a connecting piece. The plate surface of the connecting plate 22 is against the plate surface of the stove plate 10, so that the nozzle holder 20 and the stove plate 10 have a strong connection stability.

[0047] The buckle 1021 is configured as a folded edge provided on the edge of the connecting plate 22, and the folded edge is bent relative to the connecting plate 22 toward the stove plate 10. In this embodiment, the buckle 1021 and the connecting plate 22 are an integrated structure, and the buckle 1021 and the connecting plate 22 are respectively formed of a plate-like member through a sheet metal bending process to form the connecting plate 22 and the buckle 1021, and the production process is simple and the manufacturing cost is low.

[0048] Furthermore, the buckle 1021 includes a main body portion 10211 connected to the connecting plate 22 and a holding portion 10212 connected to the main body portion 10211, the holding portion 10212 is in a long strip shape, and the length direction of the holding portion 10212 is parallel to the second direction, one end of the holding portion 10212 in the length direction is connected to one end of the main body portion 10211 along the second direction, along the first direction, the holding portion 10212 and the connecting plate 22 are spaced apart, the first direction is parallel to the through direction of the first connecting hole 11 and the second connecting hole 201 and is perpendicular to the connecting plate 22, and the second direction is parallel to the plate surface of the connecting plate 22 and is perpendicular to or at an angle to the first direction. In this embodiment, the clamping portion 10212 and the connecting plate 22 are spaced apart along the first direction so that a gap space for accommodating the stove plate 10 is formed between the clamping portion 10212 and the connecting plate 22, and the clamping hole 1011 passes through the stove plate 10 along the first direction, so that the buckle 1021 can be inserted into the clamping hole 1011 along the first direction, and the clamping portion 10212 can pass through the clamping hole 1011 from one side of the stove plate 10 to the other side of the stove plate 10. Specifically, after the buckle 1021 is inserted into the buckle hole 1011 along the first direction, the buckle 1021 is moved relative to the stove plate 10 along the second direction, so that the stove plate 10 is snapped into the gap space between the clamping portion 10212 and the connecting plate 22, and the stove plate 10 is clamped by the clamping portion 10212 and the connecting plate 22, so that the stove plate 10 and the nozzle holder 20 are snapped together, and when the stove plate 10 and the nozzle holder 20 are in the snapped state, the first connecting hole 11 is aligned with the second connecting hole 201, so that the operator can insert the connecting piece into the first connecting hole 11 and the second connecting hole 201 in sequence, thereby connecting the nozzle holder 20 to the stove plate 10.

[0049] In some embodiments, Figure 5As shown, the nozzle holder 20 is a U-shaped bracket structure as a whole. Specifically, the main board body 21 includes a bottom plate portion 211 and two side plate portions 212. The bottom plate portion 211 and the side plate portions 212 are both plate-like structures. The two side plate portions 212 are respectively connected to the two opposite sides of the bottom plate portion 211, and the side plate portions 212 are perpendicular to the bottom plate portion 211, so that the main board body 21 is a U-shaped structure. The end of each side plate portion 212 away from the bottom plate portion 211 is respectively connected to a connecting plate 22, and the connecting plate 22 is perpendicular to the side plate portion 212 and parallel to the bottom plate portion 211. In this embodiment, the bottom plate 211 is used to install the gas nozzle 210. The bottom plate 211, the side plate 212 and the stove plate 10 are jointly surrounded by an open space for mixing gas and air. The U-shaped bracket is a common bracket structure, which is easy to obtain. It only has a transverse side wall, so the relative longitudinal side wall is naturally formed into an opening, which can be regarded as a circumferential opening of the open space for supplying air. When the gas nozzle 210 installed on the bottom plate 211 sprays gas toward the stove plate 10, the gas is fully mixed with the air in the open space, which is conducive to the full combustion of the gas and thus improves the combustion effect. It should be noted that the above-mentioned "transverse and longitudinal" are relative to the U-shaped cavity.

[0050] In this embodiment, the nozzle holder 20 is preferably a sheet metal stamping, such as a sheet metal stamping of an aluminum alloy plate or a steel plate, which is easy to obtain and has a simple manufacturing process. Its material, thickness, and shape are also limited to the illustrated embodiment.

[0051] In some embodiments of the present invention, please combine Figure 2 and Figure 5 As shown, along the first direction, a guide surface 10213 is provided on one end surface of the clamping portion 10212 facing the connecting plate 22, and along the second direction, the guide surface 10213 has a first end and a second end, the first end is arranged farther away from the main body 10211 than the second end, and the first end is arranged farther away from the connecting plate 22 than the second end, and the guide surface 10213 is inclined relative to the plate surface of the connecting plate 22. In the process of the nozzle holder 20 sliding relative to the stove plate 10 along the second direction, the guide surface 10213 can firstly abut against the stove plate 10, and under the guiding action of the guide surface 10213, the stove plate 10 can be smoothly clamped into the gap space between the clamping portion 10212 and the connecting plate 22.

[0052] In this embodiment, Figure 5 As shown, an avoidance groove 223 is further provided at the edge position of the connecting plate 22 relative to the clamping portion 10212, and the projection of the clamping portion 10212 on the connecting plate 22 along the first direction is located inside the avoidance groove 223. By setting the avoidance groove 223, the gap size between the clamping portion 10212 and the edge of the connecting plate 22 can be increased, and the probability of the stove plate 10 getting stuck in the gap space between the clamping portion 10212 and the connecting plate 22 can be reduced.

[0053] In this embodiment, Figure 5 As shown, a support structure 224 for supporting the connecting piece is also provided on the connecting plate 22. The support structure 224 is a tubular structure. The support structure 224 is arranged around the second connecting hole 201 and is arranged on the side of the connecting plate 22 away from the stove plate 10.
