Description

Technical Field

[0001] This utility model relates to the field of igniter technology, and in particular to infrared igniters. Background Technology

[0002] In the field of ignition technology, traditional igniters are mainly divided into two categories: open flame igniters (such as electric spark igniters) and ordinary infrared radiation igniters. Open flame igniters directly ignite gas through an electric arc or electric spark, but their flames are exposed to the external environment and are easily affected by external airflow. Ordinary infrared radiation igniters absorb heat and radiate infrared rays through infrared radiation materials (such as ceramic radiation layers) to ignite the surrounding gas. They have the characteristics of concealed flames and high thermal efficiency, and are widely used in household gas stoves, industrial combustion equipment, and outdoor heating devices.

[0003] However, existing ordinary infrared radiation igniters have significant drawbacks when used in strong wind environments: strong winds directly impact the flame area inside the igniter. On the one hand, the high-speed airflow quickly carries away the heat from the surface of the infrared radiation material, causing its temperature to drop and reducing infrared radiation efficiency. On the other hand, strong winds disperse the mixture of gas and air, disrupting the continuity of the flame and even extinguishing it. Specifically, the structural design of traditional igniters is usually open or semi-open, allowing external airflow to freely enter the core flame area. However, the infrared radiation material itself lacks measures to guide and stabilize the airflow, causing the igniter to easily fail due to wind interference in outdoor (such as barbecues or fieldwork) or well-ventilated industrial settings, making it unable to maintain stable combustion.

[0004] To address the aforementioned problems, this invention provides an infrared igniter that solves the technical issue of poor flame stability in strong wind environments by optimizing the airflow guidance structure and thermal management method. Specifically, this invention guides external airflow tangentially into the igniter to form a vortex, reducing the direct impact of the airflow on the flame. Simultaneously, a first fixing frame made of thermally conductive material transfers heat from the infrared radiation layer to the airflow channel, preheating the incoming air and improving the mixing efficiency of the gas and air. The preheated airflow is precisely delivered to the first slot of the infrared radiation layer through a connecting pipe, where it mixes thoroughly with the gas and is ignited by infrared radiation, forming a stable flame core. This ensures the flame's continuity and stability even in strong wind environments. Utility Model Content

[0005] To overcome the problem that when traditional igniters are used in daily operations in strong wind environments, strong winds can interfere with the flame, reduce the temperature of infrared radiation materials, disperse the flame, and affect its stability.

[0006] The technical solution of this utility model is as follows: an infrared igniter, comprising a fixed base, a fixed plate, an infrared radiation layer, a first fixed frame, a second fixed frame, a connecting pipe, a first slot, a flow guiding component, a gas supply component, an ignition component, and a control component. A fixed plate is disposed above the fixed base, and an infrared radiation layer is disposed on the inner side of the fixed plate. Multiple sets of first slots are opened on the inner side of the infrared radiation layer. A first fixed frame is disposed above the fixed plate, and a second fixed frame is disposed above the fixed plate. Multiple sets of connecting pipes are disposed on one side of the first fixed frame, and these connecting pipes are interconnected with the infrared radiation layer. Each connecting pipe corresponds to a first slot. A flow guiding component is disposed on the outer side of the second fixed frame, and a gas supply component is disposed below the fixed base. An ignition component is disposed above the fixed plate, and a control component is disposed below the fixed base. The flow guiding component includes a flow guiding frame and a flow guiding groove. Multiple sets of flow guiding frames are disposed on the outer side of the second fixed frame, and multiple sets of oblique flow guiding grooves are opened on the inner side of the flow guiding frames.

[0007] Preferably, a cavity structure is formed through the gap between the first and second fixed frames, allowing airflow to pass through. The airflow outside the second fixed frame enters the cavity structure tangentially along the guide groove inside the guide frame, generating a swirling flow. The first fixed frame is made of a thermally conductive material, transferring heat to the cavity structure to preheat the airflow inside. The preheated airflow enters the first slot along the connecting pipe and contacts the infrared radiation layer. At the same time, the airflow mixes with the gas surrounding the infrared radiation layer and is ignited by the infrared radiation of the infrared radiation layer, forming a stable flame core. After the initial flame is formed inside the ignition device, the stability and continuity of the flame are maintained. This device improves the stability of the flame in strong wind environments by introducing external airflow into the device for preheating and mixing it with the gas, making it suitable for use in strong wind environments.

[0008] Preferably, the gas transmission assembly includes a first flange and fixing bolts, with the first flange provided on the bottom surface of the mounting base and the fixing bolts provided below the first flange.

[0009] Preferably, the gas transmission assembly also includes a gas transmission pipe and a second flange, with the gas transmission pipe located below the first flange and the second flange located at the lower end of the gas transmission pipe.

[0010] Preferably, the ignition assembly includes a fixing block and an arc generator, with multiple sets of fixing blocks disposed above the fixing plate and an arc generator disposed above the fixing blocks.

[0011] Preferably, the control assembly includes a mounting bracket and a control knob, with the mounting bracket located below the mounting base and the control knob located on one side of the mounting bracket.

[0012] Preferably, the inner side of the second fixing frame is provided with a spiral guide vane, and multiple sets of spiral guide vanes are provided.

[0013] Preferably, a tapered frame is provided on the inner side of the first fixing frame, and the tapered frame has a structure that is narrow at the top and wide at the bottom.

[0014] The beneficial effects of this utility model are:

[0015] A cavity structure is formed by the gap between the first and second fixed frames, allowing airflow to pass through. The airflow outside the second fixed frame enters the cavity structure tangentially along the guide groove inside the guide frame, generating a swirling flow. The first fixed frame is made of thermally conductive material, which transfers heat to the cavity structure, preheating the airflow inside. The preheated airflow enters the first slot along the connecting pipe and contacts the infrared radiation layer. At the same time, the airflow mixes with the gas around the infrared radiation layer and is ignited by the infrared radiation of the infrared radiation layer, forming a stable flame core. After the initial flame is formed inside the ignition device, the stability and continuity of the flame are maintained. This device improves the stability of the flame in strong wind environments by introducing external airflow into the device for preheating and mixing with the gas, making it suitable for use in strong wind environments.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment of an infrared igniter, comprising a fixed base 1, a fixed plate 2, an infrared radiation layer 3, a first fixed frame 4, a second fixed frame 5, connecting pipes 6, first slots 7, a flow guiding component, a gas supply component, an ignition component, and a control component. The fixed plate 2 is positioned above the fixed base 1, and the infrared radiation layer 3 is positioned inside the fixed plate 2. Multiple sets of first slots 7 are formed on the inner side of the infrared radiation layer 3. The first fixed frame 4 is positioned above the fixed plate 2, and the second fixed frame 5 is positioned above the fixed plate 2. Multiple sets of connecting pipes 6 are positioned on one side of the first fixed frame 4, and the multiple sets of connecting pipes 6 are interconnected with the infrared radiation layer 3. Each connecting pipe 6 corresponds to one of the first slots 7. A flow guiding component is positioned on the outer side of the second fixed frame 5. A gas supply component is positioned below the fixed base 1, and an ignition component is positioned above the fixed plate 2. The fire assembly has a control component located below the fixing base 1. The flow guiding component includes a flow guide frame 101 and a flow guide groove 102. Multiple sets of flow guide frames 101 are provided on the outer side of the second fixing frame 5, and multiple sets of oblique flow guide grooves 102 are opened on the inner side of the flow guide frame 101. A cavity structure that allows airflow to pass through is formed through the gap between the first fixing frame 4 and the second fixing frame 5. The airflow outside the second fixing frame 5 enters the cavity structure tangentially along the flow guide groove 102 inside the flow guide frame 101 and generates a swirling flow. The first fixing frame 4 is made of a heat-conducting material, which transfers heat to the cavity structure and preheats the airflow inside the cavity structure. The preheated airflow enters the first slot hole 7 along the connecting pipe 6 and comes into contact with the infrared radiation layer 3. At the same time, the airflow mixes with the gas around the infrared radiation layer 3 and is ignited by the infrared radiation of the infrared radiation layer 3 to form a stable fire core.

[0023] Please see Figure 3 and Figure 4 In this embodiment, the gas transmission assembly includes a first flange 201 and a fixing bolt 202. The bottom surface of the fixing seat 1 is provided with the first flange 201, and the fixing bolt 202 is provided below the first flange 201. In use, the first flange 201 and the fixing seat 1 are connected and fixed by the fixing bolt 202. The gas transmission assembly also includes a gas transmission pipe 203 and a second flange 204. The gas transmission pipe 203 is provided below the first flange 201, and the lower end of the gas transmission pipe 203 is provided with the second flange 204. In use, the second flange 204 is connected to the pipeline of the external gas transmission equipment to transport the gas along the gas transmission pipe 203 to the infrared radiation layer 3.

[0024] The ignition assembly includes a fixing block 301 and an arc generator 302. Multiple fixing blocks 301 are positioned above the fixing plate 2, and the arc generator 302 is positioned above the fixing blocks 301. During use, the arc generator 302 generates an arc, igniting the gas in the initial stage when it is delivered to the infrared radiation layer 3, forming an initial flame. The control assembly includes a mounting bracket 401 and a control knob 402. The mounting bracket 401 is positioned below the fixing base 1, and the control knob 402 is positioned on one side of the mounting bracket 401. During use, the control knob 402... 2. The arc generator 302 is controlled to open and close. The inner side of the second fixed frame 5 is provided with a spiral guide plate 501. Multiple sets of spiral guide plates 501 are provided. In use, the stability of the swirling structure formed by the airflow in the cavity structure between the first fixed frame 4 and the second fixed frame 5 is achieved through multiple sets of spiral guide plates 501. The inner side of the first fixed frame 4 is provided with a conical frame 601. The conical frame 601 has a narrow upper and wide lower structure. In use, the narrow upper and wide lower structure of the conical frame 601 forms the flame jet outlet, reducing the interference of external airflow on the infrared radiation layer 3 inside the device.

[0025] During operation, the gas supply assembly is first connected to the pipeline of the external gas supply equipment via the second flange 204, thus connecting the gas supply pipe 203 to the gas source. Then, the first flange 201 is fixed to the bottom surface of the fixed base 1 using the fixing bolts 202 to ensure a sealed connection between the gas supply pipe 203 and the fixed base 1. Finally, the mounting bracket 401 of the control assembly is fixed below the fixed base 1 to complete the overall assembly. At this time, the gas can be supplied to the top of the fixed base 1 through the gas supply pipe 203 and gradually diffuses to the area around the infrared radiation layer 3, preparing for ignition.

[0026] When ignition is initiated, the arc generator 302 of the ignition assembly is activated by the control knob 402 of the control assembly. The arc generator 302 generates a high-frequency arc under the support of the fixing block 301, igniting the gas gathered around the infrared radiation layer 3 to form an initial flame. At the same time, the external airflow, guided by the flow guide assembly, enters the cavity structure between the first fixing frame 4 and the second fixing frame 5 tangentially along the inclined flow guide groove 102 on the inner side of the flow guide frame 101, forming a spiral vortex. The first fixing frame 4 transfers the heat of the infrared radiation layer 3 into the cavity to preheat the air in the vortex. The preheated airflow is precisely delivered to the first slot 7 of the infrared radiation layer 3 through the connecting pipe 6, and after being fully mixed with the gas, it is further ignited by infrared radiation to form a stable flame core, achieving continuous combustion of the flame.

[0027] When used in strong winds, the multiple sets of spiral guide vanes 501 on the inner side of the second mounting bracket 5 can enhance the stability of the swirling flow inside the cavity and prevent high-speed airflow from directly impacting the flame core area; the conical bracket 601 on the inner side of the first mounting bracket 4 forms a flame jet outlet, reducing the interference of external airflow on the internal flame core by reducing the outlet area; at the same time, the first mounting bracket 4, made of thermally conductive material, continuously transfers the heat of the infrared radiation layer 3 to the airflow channel, maintaining preheating efficiency and ensuring that the mixture of gas and air is always within the suitable ignition temperature range; the synergistic effect of the above structures enables the igniter to maintain the continuity and stability of the flame in strong winds, effectively solving the problem that traditional igniters are easily blown out by the wind.

[0028] Through the above steps, a cavity structure that can be used for airflow is formed by utilizing the gap between the first fixing frame 4 and the second fixing frame 5. The airflow outside the second fixing frame 5 enters the cavity structure tangentially along the guide groove 102 in the guide frame 101 to generate swirling flow. The first fixing frame 4 is made of thermally conductive material, which transfers heat to the cavity structure to preheat the airflow inside the cavity structure. The preheated airflow enters the first slot 7 along the connecting pipe 6 and comes into contact with the infrared radiation layer 3. At the same time, the airflow mixes with the gas around the infrared radiation layer 3 and is ignited by the infrared radiation of the infrared radiation layer 3 to form a stable flame core. After the initial flame is formed inside the ignition device, the stability and continuity of the flame are maintained. This device utilizes the introduction of external airflow into the device for preheating and mixing with the gas to improve the stability of the flame in strong wind environments, making it suitable for use in strong wind environments.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
