The present invention proposes a combustion channel structure 100 for a burner including a gas outlet.

1 to 6 , the combustion channel structure 100 proposed by the technical solution of the present invention includes:

a spacer 10 formed with a first through hole 11; and

The communicating piece 20, the communicating piece 20 and the isolating piece 10 are stacked and arranged to enclose together the combustion channel 40, the communicating piece 20 is formed with a notch 21, the notch 21 and the first through hole 11 is communicated and communicated with the combustion channel 40, and the first through hole 11 or the notch 21 is communicated with the gas outlet.

The technical solution of the present invention is to provide a spacer 10 with a first through hole 11 and a communication piece 20 with a gap 21. By stacking the spacer 10 and the communication piece 20 to form a combustion channel 40, the gap is further formed. 21 communicates with the first through hole 11 and communicates with the combustion channel 40. When a gas-fired structure needs to be used, the first through hole 11 or the gap 21 is communicated with the gas outlet, and the gas outlet can be the gas outlet after the gas is mixed with air, In this way, the mixed gas can be fully mixed in the combustion channel; or the gas outlet is an air outlet, or the gas outlet is a gas outlet. Specifically, the first through hole 11 can be connected to the gas outlet of the gas channel, and the air channel The gas outlet can be communicated with the combustion channel 40; alternatively, the notch 21 can be connected with the gas outlet of the air channel, and the gas outlet of the gas channel can be communicated with the combustion channel 40, so that gas and air can pass through the first through hole 11 or the gap. 21 flows through and enters the combustion passage 40 for mixing. Since the combustion duct 40 is formed by the split structure, when the combustion duct 40 needs to be adjusted, the spacer 10 and the connecting piece 20 can be re-adjusted and assembled, which greatly improves the versatility of the combustion duct 40, and the parts of the split body are generally smaller than The overall combustion channel structure 100 reduces the size and shape of the mold and reduces the cost of the mold.

In this embodiment, the material of the spacer 10 and the communication member 20 can be made of metal, so as to improve the heat resistance and make the combustion channel structure 100 more stable. In some embodiments, the stacked spacers 10 and the communicating members 20 may be sequentially connected together by spot welding, or may be sequentially fixed together by stamping.

In some embodiments of the present invention, the value range of the diameter d of the first through hole 11 is 0.1mm≤d≤10mm, and when the value of the diameter is less than 0.1mm, the gas or air flow rate will be small. , it is necessary to set more through holes to ensure sufficient flow of the two. When the value of the aperture is greater than 10mm, the hollow area of the spacer 10 will be increased, and the strength of the spacer 10 will be reduced, which is not conducive to ensuring the combustion channel 40. The structure is stable. When the value range of the aperture d is 0.1mm≤d≤10mm, on the one hand, it is convenient to ensure sufficient air flow, and on the other hand, it can also ensure the structural strength of the spacer 10 . It can be understood that the value of the aperture d can also be 0.2mm, 0.5mm, 0.7mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., which is convenient to ensure sufficient On the other hand, the structural strength of the spacer 10 can be guaranteed. The first through hole 11 can be gradually reduced from the air inlet side to the air outlet side. This arrangement can increase the flow velocity of the fluid when the gas is out. When the gas outlet is an air outlet, or the gas outlet is a gas outlet, the air can be ensured. The contact efficiency with the gas improves the combustion efficiency of the gas. And, when the diameter of the first through hole 11 is not in the range of 1mm≤d≤10mm, the gas pressure of the mixed gas flowing out of the first through hole 11 is likely to be too high, and then directly sprayed into the first through hole 11 on the other side, The air outlet efficiency of the first through hole 11 is greatly reduced, or the air pressure of the first through hole 11 flowing out of the first through hole 11 is insufficient, and the space of the combustion channel 40 cannot be fully utilized. When the diameter of the first through hole 11 is in the range of 1 mm≤d≤10 mm, the mixed gas can be uniformly distributed in the combustion channel 40, and the combustion efficiency can be improved. It can be understood that the value of the aperture d can also be 0.2mm, 0.5mm, 0.7mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., which can make the mixed gas evenly distributed in the combustion chamber. Road 40, improve combustion efficiency.

In some embodiments of the present invention, the opening of the notch 21 may be consistent with the size of the aperture of the first through hole 11 , so that the fluid flowing out of the first through hole 11 flows from the notch 21 into the combustion passage 40 . The notch 21 can also be arranged in the shape of a through hole, and the hole wall of the hole can be penetrated by providing a communication groove. When needed, the through hole is communicated with the first through hole 11, or directly connected with the outlet of the air channel or the gas channel. The gas port is connected, and the communication groove is communicated with the combustion channel 40, so that the combustion channel 40 can be formed by the spacer 10 and the communication member 20, and it is convenient to use. Further, the communication groove may communicate with the through hole from the interior of the communication member 20 , or communicate with the through hole on the surface of the communication member 20 , as long as it is convenient to communicate the through hole with the combustion channel 40 .

It can be understood that, the air channel and the gas channel are specifically communicated with the first through hole 11 or the gap 21, which is not limited here, and can be determined according to the stacking form adopted by the user. At least one of the air and the gas flows into the combustion channel 40 from the first through hole 11 or the gap 21 , and the other is directly connected to the combustion channel 40 to realize mixing in the combustion channel 40 .

In some embodiments of the present invention, the number of the isolation members 10 and the number of the communication members 20 are both multiple, and the isolation members 10 and the communication members 20 are alternately stacked, so that the first The through holes 11 communicate with the notches 21 alternately. In one embodiment, the shape of the spacer 10 and the connecting member 20 can be arranged in a plate shape, so that the length of the first through hole 11 and the notch 21 to be penetrated can be shortened, and the processing efficiency can be improved. Moreover, by stacking multiple spacers 10 , the length of the combustion channel 40 can be flexibly adjusted, which greatly improves the versatility of the combustion channel 40 . The thickness of the spacer 10 and the communication member 20 can also be set according to the actual situation, and the spacer 10 and the communication member 20 with different thicknesses can also be stacked to further improve the adaptability of the combustion channel structure 100 . Specifically, the thickness of the spacer 10 and the communication member 20 can be any value between 0.5mm and 100mm (specifically, 1mm, 2mm, 5mm, 10mm, 20mm, 50mm, 70mm, 90mm, etc.), as long as It is sufficient to ensure that the spacer 10 has a certain strength and to facilitate the formation of the first through holes 11 . Similarly, the thickness of the communication piece 20 can be any value between 0.5mm and 100mm (specifically, it can be 1mm, 2mm, 5mm, 10mm, 20mm, 50mm, 70mm, 90mm, etc.) A certain strength is sufficient, and the notch 21 can be easily formed. Moreover, the alternate arrangement can make the distribution of the notches 21 uniform, so that the fluid entering the first through hole 11 can be easily introduced into the combustion passage 40, thereby improving the combustion efficiency. It should be noted that the alternation in this embodiment does not only mean a form of stacking one piece of spacer 10 with one piece of connecting piece 20 and then another piece of spacer 10 , but also includes stacking multiple pieces of connecting piece on one piece of spacer 10 . 20, the form of stacking multiple pieces of spacers 10 on one piece of connecting piece 20, and stacking m pieces of connecting pieces 20 on n pieces of spacer 10 (n and m can be equal or unequal values), as long as It is sufficient to facilitate the distribution of the gaps 21 .
