DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0018] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0019] like Figures 1 to 12The ignition device shown in the figure comprises a shell 1, a gas box 2 and an ignition member 3 are arranged in the shell 1, an inner cavity for storing gas is arranged inside the gas box 2, a gas outlet 4 is connected to the gas box 2, an operating member 5 for opening and closing the gas outlet 4 and controlling the ignition member 3 is arranged on the shell 1, an ignition groove 6 is arranged at one end of the shell 1, and the inner wall of the ignition groove 6 is provided with at least one group of ignition ports that can spray flames toward the center of the ignition groove 6, the ignition ports include an open flame port 7 and a straight flush port 8, and the shell 1 is provided with a position corresponding to the open flame port 7 and the straight flush port 8 The corresponding open flame nozzles 9 and straight-injection nozzles 10 are arranged, and the gas outlet 4 includes a first gas nozzle 11 and a second gas nozzle 12 that supply gas to the open flame nozzles 9 and the straight-injection nozzles 10 respectively. The ignition element 3 is used to ignite one of the open flame ports 7 or the straight-injection ports 8 (the ignition element 3 preferably adopts piezoelectric electronics, of course, other structures that can ignite the gas are also possible. When the first gas nozzle 11 and the second gas nozzle 12 are deflated, the lead of the piezoelectric electronics is guided to one of the open flame ports 7 or the straight-injection ports 8, so that the adjacent open flame ports 7 and the straight-injection ports 8 can be ignited. ignite in sequence), in this embodiment, three open flame nozzles 9 are preferably provided, and four direct-injection nozzles 10 are preferably provided. The first gas nozzle 11 is a four-way valve and the first gas nozzle 11 is connected to the intake pipe 23 through three mixed gas pipes 29, and the second gas nozzle 12 is a five-way valve and the second gas nozzle 12 is connected to the direct-injection nozzle 10 through four mixed gas pipes 29. The number of open flame nozzles 9 and direct-injection nozzles 10 can be set according to actual conditions and is not limited to the above-mentioned examples. In this embodiment, the working principle of the direct-injection nozzle 10, the first and second The working principle of the air nozzle 12 is the existing technology and will not be elaborated in detail in this application; the ignition component 3 preferably adopts piezoelectric electronics, and the lead of the piezoelectric electronics is extended to one of the open flame ports 7 or the straight-in port 8, and the other adjacent open flame ports 7 and straight-in port 8 will be ignited at the same time. The preferred method is: extend the lead of the piezoelectric electronics to the straight-in nozzle 10 at the head or tail of the ignition slot 6, and try not to place the lead in the center of the straight-in nozzle 10, and set it on the periphery of the straight-in nozzle 10. The specific position depends on the actual situation.

[0020] The inner wall of the ignition groove 6 is alternately arranged with multiple open flame ports 7 and straight ports 8. Only one of the open flame ports 7 or the straight ports 8 needs to be ignited to make all the open flame ports 7 and the straight ports 8 in the ignition groove 6 emit flames. The straight flame is directional and can concentrate heat at a specific position. The open flame can cover a wider area. The two are used alternately to increase the combustion area. Combined, precise temperature control and local combustion can be performed in many aspects. Since the straight flame can provide concentrated high temperature at a specific position and quickly heat the target object, combined with the temperature control of the open flame, the inner wall of the ignition groove 6 can be quickly heated, which can reduce unnecessary energy waste and improve the overall energy utilization rate. After the combustible gas ejected from the straight port 8 is ignited, it will form a chain reaction of combustion with the surrounding air. The high temperature generated by the combustion will cause the combustible mixture at the adjacent open flame port 7 to reach the ignition point and be ignited. The open flame port will also heat the surrounding environment when burning. When combustible gas is ejected from the next straight jet port 8 and mixed with air to form a combustible mixture of appropriate proportions, it will also be ignited by the flame of the open flame port 7, achieving progressive ignition.

[0021] The ignition groove 6 has an annular inner wall 13 and a bottom wall 14, and the open flame port 7 and the straight-injection port 8 are alternately arranged along the circumferential direction of the annular inner wall 13. The open flame and the straight-injection flame are ejected toward the center of the ignition groove 6, which combines the characteristics of large-area combustion of the open flame and the characteristics of fixed-point high-temperature combustion of the straight-injection flame. The interior of the ignition groove 6 heats up quickly, which is suitable for outdoor use and can be used to ignite barbecue charcoal, etc. In this embodiment, the annular inner wall 13 is a conical surface with a large upper portion and a small lower portion. After the object to be burned is inserted into the ignition groove 6, there is a gap between the straight-injection port 8 and the open flame port 7 and the object to be burned. Avoid space to prevent the open flame port 7 and the straight-out port 8 from being too close to the object to be burned, which may cause air flow obstruction and insufficient oxygen supply, thereby improving the integrity and efficiency of combustion. In this embodiment, at least two groups of ignition ports are provided, and three or four groups can also be provided according to actual conditions. Multiple open flame ports 7 and straight-out ports 8 are alternately arranged along the circumferential direction of the annular inner wall 13. When the first gas nozzle and the second gas nozzle are in the exhaust state, the ignition component 3 ignites one of the straight-out ports 8, which can make the adjacent open flame ports 7 and the straight-out ports 8 of the adjacent open flame ports 7 ignite in turn to achieve progressive ignition.
