Description

Technical Field

[0001] This utility model relates to the field of stove head technology, and in particular to a stove head structure for a high-powered stove. Background Technology

[0002] In the field of gas heating equipment, the burner head is a core component, and its structural design and performance directly affect the combustion efficiency and performance of the equipment.

[0003] Chinese Patent Document No. CN 207094674 U, published on March 13, 2018, discloses an energy-saving five-cavity direct-injection high-power stove, comprising a nozzle copper tube, a copper sleeve, a burner distributor, and a burner head aluminum base. Several nozzle copper tubes are inserted into the burner head aluminum base, and a copper sleeve is fitted onto each nozzle copper tube. The copper sleeve has a raised edge, the width of which is greater than the diameter of the nozzle copper tube below. A through hole corresponding to the nozzle copper tube is opened above the copper sleeve. A burner distributor is installed above the nozzle copper tube, and the burner distributor is a porous structure for gas to pass through. The nozzle copper tube inserted in the middle of the burner head aluminum base is a central nozzle copper tube, and the burner distributor installed on the central nozzle copper tube is a central burner distributor. The central burner distributor has a structure with a sealed top and holes around the perimeter. The four nozzle copper tubes around the burner head aluminum base are outer ring nozzle copper tubes, and the burner distributor installed on the outer ring nozzle copper tubes is an outer ring burner distributor. The center of the outer ring burner distributor has a porous structure for gas to be ejected, and the porous structure is surrounded by a flame-collecting edge.

[0004] The nozzle copper tube of this energy-saving five-cavity direct-injection high-power stove has an air inlet at the bottom, which is used to mix gas and air to create a mixed airflow. However, the inner wall of the nozzle copper tube is a smooth surface, which prevents the gas and air from being fully and effectively mixed after entering the nozzle copper tube. During the upward process of the mixed airflow, the gas and air, lacking effective disturbance and guidance, can only flow upward rapidly and be output for combustion, resulting in poor mixing and incomplete combustion, thus causing energy waste. At the same time, it may also produce harmful gases such as carbon monoxide, affecting the safety and environmental protection of use. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a burner head structure for a high-powered stove that ensures good air-gas mixing and complete combustion, thereby overcoming the shortcomings of the prior art.

[0006] A furnace head structure for a high-powered stove designed for this purpose includes a furnace base with a gas flow channel, an installation hole on the furnace base, a gas nozzle disposed in the installation hole, an injection channel in the gas nozzle, a fire tube sleeved on the gas nozzle, an air inlet on the side wall of the fire tube, the injection channel being connected to the interior of the fire tube and to the gas flow channel inside the furnace base, characterized in that a flow-guiding mixing plate for guiding and mixing air and gas is disposed inside the fire tube, the flow-guiding mixing plate being located above the air inlet.

[0007] Furthermore, the flow guiding and mixing plate includes at least two plates disposed opposite each other on the inner wall of the fire tube, and a mixed gas flow channel is formed between the two oppositely disposed flow guiding and mixing plates.

[0008] Furthermore, at least two flow-guiding mixing plates are arranged circumferentially along the fire tube.

[0009] Furthermore, the flow guiding and mixing plate is inclined.

[0010] Furthermore, the flow-guiding mixing plate is arranged on the inner wall of the fire tube in a left-handed or right-handed manner.

[0011] Furthermore, the flow guiding and mixing plate is a spiral plate, and the spiral axis of the flow guiding and mixing plate coincides with the axis of the fire tube.

[0012] Furthermore, the lower bottom wall of the air inlet is flush with the inner bottom wall of the fire tube.

[0013] Furthermore, the bottom of the fire tube is provided with a notch below the air inlet, and the notch is connected to the air inlet.

[0014] Furthermore, the gas nozzle is threadedly connected to the fire tube; the fire tube is provided with a threaded hole, and the gas nozzle is provided with a threaded boss that is threadedly connected to the threaded hole.

[0015] Furthermore, the flow-guiding mixing plate and the fire tube are an integral structure.

[0016] This invention features a flow-guiding mixing plate inside the fire tube for guiding and mixing air and fuel gas. The flow-guiding mixing plate is located above the air inlet. It guides and diverts the fuel gas and air entering the fire tube, promoting thorough collision, disturbance, and mixing of the two gases during flow, significantly improving mixing efficiency. After thorough mixing, the fuel gas and air achieve more complete combustion, effectively reducing emissions of harmful gases such as carbon monoxide caused by incomplete combustion, thus improving the environmental friendliness of combustion. The improved combustion efficiency allows for more efficient use of the fuel gas, reducing energy waste, extending the fuel gas usage time, and increasing the energy utilization rate of the burner. Stable and complete combustion also ensures flame stability, improves the uniformity and stability of burner heating, thereby enhancing the overall performance and effectiveness of the burner and providing users with a better experience.

[0017] This invention eliminates the need for a flame distributor located at the top of a traditional fire tube because it incorporates a flow-guiding mixing plate inside the fire tube for guiding and mixing air and fuel gas. This not only achieves complete combustion but also reduces product costs.

[0018] In summary, this utility model has the characteristics of good air-gas mixing and complete combustion. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-6 A high-powered stove head structure includes a stove base 10 with a gas flow channel 100. The stove base 10 is provided with a mounting hole 110. A gas nozzle 20 is disposed in the mounting hole 110. An injection channel 210 is provided in the gas nozzle 20. A fire tube 30 is sleeved on the gas nozzle 20. An air inlet 310 is provided on the side wall of the fire tube 30. The injection channel 210 is connected to the interior of the fire tube 30 and to the gas flow channel 100 inside the stove base 10. The characteristic feature is that a flow guiding and mixing plate 40 for guiding and mixing air and gas is provided inside the fire tube 30. The flow guiding and mixing plate 40 is located above the air inlet 310.

[0028] In this embodiment, under the action of the flow guiding mixing plate, compared with the smooth inner wall of the traditional fire tube, the flow guiding mixing plate can guide and split the gas and air entering the fire tube, so that the two gases can generate sufficient collision, disturbance and mixing during the flow process, which significantly improves the mixing efficiency.

[0029] The flow guiding and mixing plate 40 includes at least two plates disposed opposite each other on the inner wall of the fire tube 30, and a mixed gas flow channel 400 is formed between the two oppositely disposed flow guiding and mixing plates 40.

[0030] At least two flow guiding and mixing plates 40 are arranged circumferentially along the fire tube 30.

[0031] The flow guiding and mixing plate 40 is set at an angle.

[0032] The flow guiding and mixing plate 40 is arranged on the inner wall of the fire tube 30 in a left-hand or right-hand spiral.

[0033] In this embodiment, the left-hand or right-hand rotation setting allows the airflow to flow in a spiral shape along the spiral guide mixing plate 40, which not only prolongs the residence time of the airflow in the fire tube, but also increases the mixing effect, thereby providing strong support for the complete combustion of the gas.

[0034] The flow guiding mixing plate 40 is a spiral plate, and the spiral axis of the flow guiding mixing plate 40 coincides with the axis of the fire tube 30.

[0035] The lower bottom wall 311 of the air inlet 310 is flush with the inner bottom wall 300 of the fire tube 30.

[0036] The bottom of the fire tube 30 is provided with a notch 330 below the air inlet 310, and the notch 330 is connected to the air inlet 310.

[0037] In this embodiment, by setting the notch 330, the resistance to air entering the fire tube can be further reduced and the air supply can be increased, providing strong support for subsequent thorough mixing and complete combustion.

[0038] The gas nozzle 20 is threadedly connected to the fire tube 30; the fire tube 30 is provided with a threaded hole 320, and the gas nozzle 20 is provided with a threaded boss 220 that is threadedly connected to the threaded hole 320.

[0039] The flow guiding mixing plate 40 and the fire tube 30 are an integral structure.
