[0029] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0030] Refer to the following Figures 1 - 3 to describe the burner device 10 according to an embodiment of the present application. The burner device 10 includes a main body portion, a gas distribution plate assembly 11 and a mixing device. A combustion cavity is formed inside the main body portion. The gas distribution plate assembly 11 has a gas distribution plate body 111, a connecting pipe 112 and a cover body 113. The gas distribution plate body 111 is connected to the main body portion. The connecting pipe 112 is disposed on a side of the gas distribution plate body 111 facing away from the main body portion and extends in a direction away from the gas distribution plate body 111. The cover body 113 is connected to the free end of the connecting pipe 112. The gas distribution plate body 111, the connecting pipe 112 and the cover body 113 are configured as an integrally formed part. A mixing cavity 123 is formed inside the mixing assembly 12. The mixing cavity 123 communicates with the combustion cavity through the gas distribution plate assembly 11. The mixing assembly 12 is connected to the cover body 113; wherein the connecting pipe 112 is configured to have an increasing cross-sectional area in the direction from the cover body 113 to the gas distribution plate body 111.

[0031] Currently, burners usually adopt the full premix combustion mode. Full premix combustion means that before combustion, fuel and air are fully premixed, and after forming a uniform mixture gas, combustion is carried out. In order to achieve uniform gas mixing, a mixing tank is required for the mixture gas, and then the gas in the mixing tank is introduced into the burner. Existing burners use a hose or a combined structure to transport the mixture gas, with low structural strength and poor conveying effect.

[0032] As Figure 1 shown, specifically, the burner device 10 includes a main body portion, a gas distribution plate assembly 11 and a mixing assembly 12. A combustion cavity can be formed inside the main body portion. Fuel can be transported into the combustion cavity and burned to generate heat and flue gas. Among them, the fuel can be a gas such as gas. The gas referred to here can be a mixture of gas and air. The gas distribution plate assembly 11. The gas distribution plate assembly 11 has a gas distribution plate body 111, a connecting pipe 112 and a cover body 113. The gas distribution plate body 111 can be connected to the main body portion. Optionally, the gas distribution plate and the main body portion can form a detachable connection through screws, bolts, or the gas distribution plate and the main body portion can form a detachable connection through snap connection or plug connection, or the gas distribution plate and the main body portion are directly welded and fixed through the contact surface.

[0033] The connecting pipe 112 can be disposed on a side of the gas distribution plate body 111 facing away from the main body portion, and the connecting pipe 112 can extend in a direction away from the gas distribution plate body 111. The cover body 113 can be disposed at the free end of the connecting pipe 112. Further, the gas distribution plate body 111, the connecting pipe 112 and the cover body 113 can be configured as an integrally formed part. Adopting the above structure can improve the overall structural strength of the gas distribution plate assembly 11, prevent gas leakage during transportation, facilitate the processing of the gas distribution plate assembly 11, reduce the mold cost, and improve the service life of the burner device 10.

[0034] A mixing flow component 12 may form a mixing flow cavity 123 therein. The mixing flow cavity 123 can be used for mixing gas and air, and the mixing flow cavity 123 and the combustion cavity can be communicated through a gas distribution plate component 11, so that the mixed gas can be guided to the combustion cavity through the gas distribution plate component 11 for combustion. Specifically, the mixing flow component 12 can be connected to the cover body 113. Optionally, the cover body 113 and the mixing flow component 12 can be arranged opposite to each other and sealed, so as to close the mixing flow cavity 123, ensure the sealing performance of the mixing flow cavity 123, prevent the mixed gas from leaking from the connection between the cover body 113 and the mixing flow component 12, and improve the safety performance of the burner device 10.

[0035] Furthermore, the connecting pipe 112 is configured to have an increasing cross-sectional area in the direction from the cover body 113 to the gas distribution plate body 111. When the gas and air are mixed and pass through the connecting pipe 112, as the cross-sectional area increases, the mixed gas diffuses more uniformly into the gas distribution plate body, which is beneficial to the uniform distribution of the concentration field. And the flow rate of the mixed gas will also be reduced when flowing through the connecting pipe 112, thereby reducing the frictional loss and energy loss between the mixed gas and the inner wall of the connecting pipe 112. Since gas is prone to generate eddies and noise when flowing through a pipeline with a small inner diameter, therefore, adopting the above-mentioned connecting pipe 112 can also reduce the noise and vibration when the mixed gas passes through the connecting pipe 112, thereby improving the stability and reliability of the connecting pipe 112.

[0036] In short, the burner device 10 of the embodiment of the present application is provided with a main body part and a mixing flow component 12. A combustion cavity for gas combustion is formed in the main body part, and a mixing flow cavity 123 for mixing gas and air is formed in the mixing flow component 12. The main body part and the mixing flow component 12 are respectively connected to the gas distribution plate body 111 and the cover body 113. The gas distribution plate body 111 and the cover body 113 are connected through a connecting pipe 112. The connecting pipe 112 can communicate the combustion cavity and the mixing flow cavity 123, and the cross-sectional area of the connecting pipe 112 increases in the direction from the cover body 113 to the gas distribution plate body 111, so that the mixed gas diffuses more uniformly into the combustion cavity, which is beneficial to the uniform distribution of the concentration field.

[0037] Such as Figure 2As shown, in some embodiments of the present application, the side wall of the gas distribution plate body 111 facing the connecting pipe 112 is the first wall, and the included angle between the peripheral wall of the connecting pipe 112 and the first wall is α. The included angle between the peripheral wall of the connecting pipe 112 and the first wall satisfies the following condition: 30° ≤ α ≤ 60°. In some embodiments, α is preferably 45°. By setting the included angle between the peripheral wall of the connecting pipe 112 and the first wall within the above range, it can be ensured that the mixed gas diffuses more uniformly into the shunt plate body, which is beneficial to the uniform distribution of the concentration field. In some embodiments, the connecting pipe 112 can be configured as a pyramid shape or a frustum shape, but is not limited thereto. The connecting pipe 112 can also be configured as other shapes with a gradually expanding form.

[0038] As Figure 3 shown, in some embodiments of the present application, the first communication hole 1121 and the second communication hole 1122 can be respectively formed at both axial ends of the connecting pipe 112. The first communication hole 1121 can communicate with the combustion cavity, and the second communication hole 1122 can communicate with the mixed flow cavity 123. The connecting pipe 112 also has a communication channel 1123 that connects the first communication hole 1121 and the second communication hole 1122, and the communication channel 1123 is configured to have a gradually increasing cross-sectional area in the direction from the cover body 113 to the gas distribution plate body 111. Among them, the cross-sectional area of the first communication hole 1121 perpendicular to the extension direction of the connecting pipe 112 is S1, and the cross-sectional area of the second communication hole 1122 perpendicular to the extension direction of the connecting pipe 112 is S2. The cross-sectional area of the first communication hole 1121 perpendicular to the extension direction of the connecting pipe 112 and the cross-sectional area of the second communication hole 1122 perpendicular to the extension direction of the connecting pipe 112 can satisfy the following relational expression: 3 ≤ S1 / S2 ≤ 7. By adopting the above structure, the flow rate of the mixed gas can be reduced when flowing from the second communication hole 1122 to the first communication hole 1121, thereby reducing the frictional loss and energy loss between the mixed gas and the inner wall of the connecting pipe 112. Moreover, the connecting pipe 112 with the above structure can also reduce the noise and vibration when the mixed gas passes through the connecting pipe 112, thereby improving the stability and reliability of the connecting pipe 112.

[0039] In some embodiments of the present application, the thickness of the peripheral wall of the connecting pipe 112 is d, and the thickness of the peripheral wall of the connecting pipe 112 can satisfy the following relational expression: 0.5 mm ≤ d ≤ 1.5 mm. In some embodiments, d is preferably 1 mm. Without changing the overall structural size of the connecting pipe 112, by reducing the thickness of the peripheral wall of the connecting pipe 112, the flow rate of the mixed gas in the communication channel 1123 can be increased. By setting the thickness of the peripheral wall of the connecting pipe 112 within the range, the flow rate of the mixed gas can be increased on the premise of ensuring the structural strength of the connecting pipe 112, and the reliability of the connecting pipe 112 is improved.

[0040] AsFigure 1 As shown, in some embodiments of the present application, the mixing component 12 includes a mixing housing 121 and a blower 122. A mixing cavity 123 can be formed inside the mixing housing 121, and the mixing housing 121 can have a connection end that is open towards the main body portion. The cover 113 can be connected to the connection end to close the connection end. Here, the locked closure means that the cover 113 is connected to the connection end to ensure that the gas after mixing inside the mixing cavity 123 can flow into the combustion cavity, and to prevent gas from leaking from the connection between the cover 113 and the mixing housing 121. A gas inlet 124 and an air inlet 125 are also formed inside the mixing housing 121. The gas inlet 124 and the air inlet 125 can communicate with the mixing cavity 123. It can be understood that the gas inlet 124 can be used to transport gas, and the air inlet 125 can be used to input air. After the air and gas enter the mixing cavity 123, they can be mixed.

[0041] As Figure 3 shown, in some embodiments, the gas inlet 124 and the air inlet 125 can be arranged opposite to each other. When the gas and air pass through the gas inlet 124 and the air inlet 125 respectively, they can directly contact and mix, thereby improving the mixing efficiency of the gas and air. The blower 122 can be arranged on the mixing housing 121. The blower 122 can introduce air into the air inlet 125 and enter the mixing cavity to mix with the gas. It should be noted that after the gas is mixed with the oxygen in the air, combustion can occur. By optimizing the mixing ratio of the gas and air, the sufficiency and efficiency of the combustion process can be ensured. It can be understood that an appropriate mixing ratio of the gas and air can maximize the energy released during the combustion process. Therefore, the use of the mixing component 12 can improve the combustion efficiency of the gas.

[0042] As Figure 1 and Figure 2As shown, in some embodiments of the present application, a first lug 1131 extending in the first direction may be formed on the cover body 113, and a second lug 1211 extending in the first direction may be formed on the mixed-flow housing 121. The second lug 1211 may be disposed opposite to the first lug 1131 and connected to the first lug 1131. Optionally, a detachable connection may be formed between the first lug 1131 and the second lug 1211 by screws or bolts. Alternatively, a detachable connection may be formed between the first lug 1131 and the second lug 1211 by snap connection or plug connection. Or the first lug 1131 and the second lug 1211 may be directly welded and fixed through the contact surface. In a specific embodiment, a first mounting hole penetrating in the thickness direction may be formed on the first lug 1131, and a second mounting hole penetrating in the thickness direction may be formed on the second lug 1211. The first mounting hole and the second mounting hole may be disposed opposite to each other in the thickness direction. The gas distribution plate assembly 11 may further include a fastener, and the fastener may pass through the first mounting hole and the second mounting hole to fix and connect the first lug 1131 and the second lug 1211. The first lug 1131 may be configured as multiple ones spaced apart on the cover body 113, and the second lug 1211 may be configured as multiple ones and disposed in one-to-one correspondence with the multiple first lugs 1131. Using multiple first lugs 1131 and second lugs 1211 can improve the mating strength between the cover body 113 and the mixed-flow housing 121.

[0043] In some embodiments of the present application, the burner device 10 further includes a flow equalizing plate. The flow equalizing plate may be located within the gas distribution plate body 111. Multiple gas distribution holes may be formed on the flow equalizing plate. Using the gas distribution holes can make the flow of the fuel gas more uniform, thereby ensuring uniform combustion after the fuel gas is ignited and good temperature uniformity of heating. A first gas distribution area and a second gas distribution area may be formed on the flow equalizing plate. The first gas distribution area and the second gas distribution area are spaced apart from each other, and the first gas distribution area is disposed opposite to the first communication hole 1121. Among them, the diameter of the gas distribution holes in the first gas distribution area is smaller than the diameter of the gas distribution holes in the second gas distribution area. Since the first gas distribution area is disposed opposite to the first communication hole 1121, the flow rate of the fuel gas at the first gas distribution area is greater than the flow rate of the fuel gas at the second gas distribution area. Therefore, under the condition that the flow velocity of the fuel gas at the first gas distribution area is greater than the flow velocity of the fuel gas at the second gas distribution area, by making the diameter of the gas distribution holes in the first gas distribution area smaller than the diameter of the gas distribution holes in the second gas distribution area, it can be ensured that the fuel gas passing amount at each part of the flow equalizing plate is uniform, so that the flame after the fuel gas is ignited can be evenly distributed. Further, the inner diameter of the gas distribution holes in the second gas distribution area gradually decreases in the direction away from the first gas distribution area, so as to ensure that the flow of the fuel gas at the flow equalizing plate is more uniform.

[0044] As Figure 1 and Figure 3As shown, in some embodiments of the present application, a flow dividing rib 1111 is further formed on one side of the gas dividing plate body 111 facing the main body portion. The flow dividing rib 1111 can extend in a direction away from the mixing flow housing 121, and the free end of the flow dividing rib 1111 can abut against the flow equalizing plate. The flow dividing ribs 1111 can be unevenly arranged. The flow dividing ribs 1111 can play a role in dividing and guiding the gas, ensuring that the gas can flow through the corresponding gas dividing holes between two adjacent flow dividing ribs 1111, and ensuring that the gas can burn more fully and evenly.

[0045] It should be noted that the above-mentioned uneven arrangement of the flow dividing ribs 1111 can be understood as that the arrangement positions of the flow dividing ribs 1111 are correspondingly set with the first gas dividing area and the second gas dividing area. The flow rate of the gas in the first gas dividing area is large. Therefore, the flow dividing ribs 1111 corresponding to the first gas dividing area are relatively dispersed, ensuring that the mixed gas can flow from the first gas dividing area to the second gas dividing areas on both sides. The flow rate of the gas in the second gas dividing area is small, and the flow dividing ribs 1111 corresponding to the second gas dividing area are relatively compact, ensuring that the mixed gas can flow to the gas dividing holes in the second gas dividing area and preventing the gas from flowing back to the first gas dividing area. The arrangement positions of the flow dividing ribs 1111 can be set according to the first gas dividing area and the second gas dividing area.
