Description

Technical Field

[0001] This utility model relates to an ignition device. Background Technology

[0002] Ignition devices, depending on their type, can produce open flames or direct-fire flames. Open flames are suitable for igniting gaseous, solid, or liquid fuels, but the flame is relatively diffuse and the ignition speed is relatively slow. When using direct-fire flames, the flame is directional and can concentrate heat on a specific location, but it cannot achieve large-area combustion, which has limitations and high energy consumption. Currently, there is a lack of ignition devices that combine the advantages of both types of flames and rationally arrange the positions of the two types of flame nozzles. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an ignition device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ignition device, comprising a housing, a gas box and an ignition element disposed within the housing, the gas box having an internal cavity for storing gas, an outlet connected to the gas box, and an operating element on the housing for opening and closing the outlet and controlling the ignition element, an ignition groove disposed at one end of the housing, the inner wall of the ignition groove having at least one set of ignition ports for spraying flame toward the center of the ignition groove, the ignition ports including an open flame port and a direct jet port, an open flame nozzle and a direct jet nozzle corresponding to the positions of the open flame port and the direct jet nozzle disposed within the housing, the outlet including a first nozzle and a second nozzle for supplying gas to the open flame nozzle and the direct jet nozzle respectively, wherein when the first nozzle and the second nozzle are in the gas-supplying state, the ignition element ignites one of the direct jet ports, thereby igniting the adjacent open flame port.

[0005] As a preferred technical solution of this utility model, the ignition groove has an annular inner wall and a bottom wall, and the ignition port is provided in at least two sets. Multiple open flame ports and direct jet ports are arranged alternately along the circumferential direction of the annular inner wall. When the first and second air nozzles are in the air-out state, the ignition element can ignite one of the direct jet ports, so that the adjacent open flame ports and the direct jet ports of the adjacent open flame ports can be ignited in sequence to achieve progressive ignition.

[0006] As a preferred technical solution of this utility model, a frame is provided inside the outer shell above the gas box. The frame is provided with a plurality of slots for embedding open flame nozzles and direct jet nozzles along the circumferential direction. The center of the frame is recessed and the shape of the recess is adapted to the shape of the ignition groove.

[0007] As a preferred technical solution of this utility model, the outer shell includes a lower shell and an upper cover, the upper cover is adapted to the shape of the frame, and the ignition groove is formed by a central recess in the upper cover.

[0008] As a preferred technical solution of this utility model, the open flame nozzle includes an air inlet seat and an air inlet plate. The air inlet seat has a first groove for accommodating the air inlet plate on the side facing the ignition slot. The air inlet plate has a second groove on the side opposite to the ignition slot. The air inlet seat has an air inlet pipe communicating with the second groove on the side opposite to the ignition slot. The air inlet plate has a plurality of air outlet holes communicating with the second groove arranged at intervals on the side facing the ignition slot.

[0009] As a preferred technical solution of this utility model, the direct-jet nozzle includes a valve seat, a direct-jet tower connected to both ends of the valve seat, and an atomizer. The valve seat is provided with a gas passage communicating with the direct-jet tower and the atomizer. The atomizer is vertically installed at the bottom of the valve seat. The direct-jet tower is located on the upper part of the valve seat and faces the ignition slot. The central axis of the direct-jet tower and the central axis of the atomizer intersect to form an angle.

[0010] As a preferred embodiment of this utility model, the valve seat has a connection hole for installing a direct-fire pagoda on the side facing the ignition slot. The inner wall of the connection hole has a threaded hole. The direct-fire pagoda includes a flame nozzle and a ceramic cup. A portion of the flame nozzle is confined inside the ceramic cup, and the other portion of the flame nozzle is located outside the ceramic cup. The portion of the flame nozzle outside the ceramic cup is threadedly connected to the threaded hole. The lower end of the valve seat has a mixing pipe that communicates with the gas passage. The mixing pipe is inserted into and fitted with an atomizer. Air inlets are provided on both sides of the mixing pipe or the atomizer. The lower end of the atomizer is connected to a second nozzle through a gas supply pipe.

[0011] As a preferred embodiment of this utility model, the air box is divided into two independent first air chambers and second air chambers, the first air nozzle is connected to the first air chamber, and the second air nozzle is connected to the second air chamber.

[0012] As a preferred technical solution of this utility model, the operating component includes two rocker arms and an operating button. The two rocker arms are oscillatingly mounted on the gas box. One end of each rocker arm is connected to the first gas nozzle and the second gas nozzle respectively to realize gas flow. The other end of the rocker arms extends to the bottom of the cap of the ignition element. The ignition element is a piezoelectric electronic component. A swinging component is hinged on the frame or the gas box. The swinging component includes a pushing part and a pressing part located at both ends of the hinge point. The pushing part is linked with the operating button. The pressing part is placed above the cap of the ignition element. Pressing the operating button towards the inside of the housing can trigger the swinging component to rotate, causing the ignition element to discharge and the gas outlet to release gas.

[0013] As a preferred technical solution of this utility model, two limiting members are rotatably installed on the gas box, which correspond to the positions of the first gas nozzle and the second gas nozzle respectively. Two movable holes are provided on the side wall of the outer shell. The two limiting members each have a lever extending out of the corresponding movable hole and a blocking part that restricts the reset of the corresponding rocker. In the ignition state, pushing the lever to rotate the blocking part to below one of the rockers can achieve continuous gas output.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: The inner wall of the ignition slot has multiple open flame ports and jet nozzles arranged alternately. Igniting just one jet nozzle will cause all the open flame ports and jet nozzles in the ignition slot to emit flames (an irradiation process proceeding sequentially along the circumference). The jet flame is directional, concentrating heat at a specific location; while the open flame can cover a wider area. The alternating use of both results in a larger combustion area. Combined, precise temperature control and localized combustion can be achieved in multiple aspects. Because the jet flame can provide concentrated high temperatures at a specific location, rapidly heating the target object, combined with the temperature control of the open flame, the inner wall of the ignition slot heats up quickly, reducing unnecessary energy waste and improving overall energy efficiency.

[0028] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] like Figures 1 to 12An ignition device is shown, comprising a housing 1, within which a gas box 2 and an ignition element 3 are disposed. The gas box 2 has an internal cavity for storing gas, and a gas outlet 4 is connected to the gas box 2. The housing 1 is provided with operating components 5 for opening and closing the gas outlet 4 and controlling the ignition element 3. One end of the housing 1 is provided with an ignition groove 6, and the inner wall of the ignition groove 6 is provided with at least one set 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 direct jet port 8. The housing 1 is provided with a device positioned adjacent to the open flame port 7 and the direct jet port 8. The corresponding open flame nozzle 9 and direct jet nozzle 10 are provided. The gas outlet 4 includes a first gas nozzle 11 and a second gas nozzle 12 that supply gas to the open flame nozzle 9 and the direct jet nozzle 10, respectively. The ignition element 3 is used to ignite one of the open flame ports 7 or the direct jet port 8 (the ignition element 3 is preferably a piezoelectric electron, but other structures capable of igniting gas are also acceptable). When the first gas nozzle 11 and the second gas nozzle 12 release gas, the lead wire of the piezoelectric electron is guided to one of the open flame ports 7 or the direct jet port 8, which can ignite adjacent open flame ports 7 and direct jet ports 8. (Ignited sequentially). In this embodiment, three open flame nozzles 9 and four direct jet nozzles 10 are preferably provided. The first air nozzle 11 is a four-way valve and is connected to the air inlet pipe 23 through three mixing pipes 29. The second air nozzle 12 is a five-way valve and is connected to the direct jet nozzle 10 through four mixing pipes 29. The number of open flame nozzles 9 and direct jet 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 jet nozzle 10, the first, and the second... The working principle of the gas nozzle 12 is existing technology and will not be described in detail in this application; the ignition element 3 preferably adopts piezoelectric electrons, and the lead wire of the piezoelectric electron is extended to one of the open flame ports 7 or direct jet ports 8. The other nearby open flame ports 7 and direct jet ports 8 will be ignited at the same time. The preferred method is to extend the lead wire of the piezoelectric electron to the direct jet nozzle 10 at the head or tail of the ignition groove 6. The lead wire should not be placed in the center of the direct jet nozzle 10 as much as possible. It can be placed on the outer periphery of the direct jet nozzle 10. The specific position depends on the actual situation.

[0031] The inner wall of the ignition slot 6 is alternately arranged with multiple open flame ports 7 and jet nozzles 8. Igniting just one open flame port 7 or jet nozzle 8 will cause all the open flame ports 7 and jet nozzles 8 within the ignition slot 6 to emit flames. The jet nozzle is directional, concentrating heat on a specific location; while the open flame covers a wider area. Alternating between the two results in a larger combustion area. Combined, precise temperature control and localized combustion can be achieved in multiple aspects. Because the jet nozzle provides concentrated high temperatures at a specific location, it rapidly heats the target object. Combined with the temperature control of the open flame, the inner wall of the ignition slot 6 heats up rapidly, reducing unnecessary energy waste and improving overall energy efficiency. The combustible gas emitted from the jet nozzle 8, once ignited, will form a chain reaction with the surrounding air, leading to combustion. The high temperature generated by combustion will cause the combustible mixture at the adjacent open flame port 7 to reach its ignition point and be ignited. The combustion of the open flame port will also heat the surrounding environment. When the next direct injection port 8 ejects combustible gas and mixes with air to form a combustible mixture in a suitable proportion, it will also be ignited by the flame at the open flame port 7, thus achieving progressive ignition.

[0032] The ignition slot 6 has an annular inner wall 13 and a bottom wall 14. The open flame port 7 and the jet nozzle 8 are alternately arranged along the circumference of the annular inner wall 13. The open flame and jet nozzle are directed towards the center of the ignition slot 6, combining the characteristics of large-area combustion of an open flame with the characteristic of fixed-point high-temperature combustion of a jet nozzle. The ignition slot 6 heats up rapidly, making it suitable for outdoor use, such as igniting barbecue charcoal. In this embodiment, the annular inner wall 13 is a conical surface, wider at the top and narrower at the bottom. After the object to be burned is inserted into the ignition slot 6, there is a distance between the jet nozzle 8 and the open flame port 7 and the object to be burned. To avoid obstructing airflow and causing insufficient oxygen supply due to the open flame port 7 and direct jet port 8 being too close to the object to be burned, thus improving the integrity and efficiency of combustion, this embodiment has at least two sets of ignition ports, or three or four sets, depending on the actual situation. Multiple open flame ports 7 and direct jet ports 8 are arranged alternately along the circumferential direction of the inner annular wall 13. When the first and second gas nozzles are in the gas output state, the ignition element 3 ignites one of the direct jet ports 8, which can sequentially ignite the adjacent open flame ports 7 and the direct jet ports 8 of the adjacent open flame ports 7 to achieve progressive ignition.

[0033] The outer casing 1 is provided with a frame 15 located above the gas box 2. The frame 15 is provided with a plurality of slots 16 at intervals along the circumference for inserting open flame nozzles 9 and direct jet nozzles 10. The center of the frame 15 is recessed and the shape of the recess is adapted to the shape of the ignition groove 6.

[0034] The outer casing 1 includes a lower casing 17 and an upper cover 18. The upper cover 18 is adapted to the shape of the frame 15, and the ignition groove 6 is formed by a central recess in the upper cover 18.

[0035] The open flame nozzle 9 includes an air inlet seat 19 and an air inlet plate 20. The air inlet seat 19 has a first groove 21 for accommodating the air inlet plate 20 on the side facing the ignition slot 6. The air inlet plate 20 has a second groove 22 on the side facing away from the ignition slot 6. The air inlet seat 19 has an air inlet pipe 23 that communicates with the second groove 22 on the side facing away from the ignition slot 6. The air inlet plate 20 has a plurality of air outlet holes 24 that communicate with the second groove 22 arranged at intervals on the side facing the ignition slot 6.

[0036] The direct-jet nozzle 10 includes a valve seat 25, a direct-jet tower 26 connected to both ends of the valve seat 25, and an atomizer 27. The valve seat 25 has a gas passage 28 that communicates with the direct-jet tower 26 and the atomizer 27. The atomizer 27 is vertically installed at the bottom of the valve seat 25. The direct-jet tower 26 is located on the upper part of the valve seat 25 and faces the ignition slot 6. The central axis of the direct-jet tower 26 and the central axis of the atomizer 27 intersect to form an angle (preferably an obtuse angle). In traditional direct-jet nozzles 10, the direct-jet tower 26 and the atomizer 27 are coaxially arranged, which can only spray flames horizontally or vertically. When the direct-jet nozzle 10 is installed horizontally, the radial dimension is large, and the volume of the outer shell 1 will increase accordingly, increasing the manufacturing cost and making it less compact.

[0037] The valve seat 25 has a connection hole for mounting the direct-fire tower 26 on the side facing the ignition slot 6. The inner wall of the connection hole has a threaded hole. The direct-fire tower 26 includes a flame nozzle 43 and a ceramic cup 44. The ceramic cup 44 is preferably a ceramic cup. In this embodiment, at least one direct-fire nozzle 10 has a channel hole 441 in the ceramic cup 44. The lead wire of the piezoelectric electron extends through the channel hole into the ceramic cup 44. Part of the flame nozzle 43 is confined inside the ceramic cup 44, and the other part of the flame nozzle 43 is located outside the ceramic cup 44. The portion of 43 located outside the ceramic cup 44 is threadedly connected to the threaded hole; the lower end of the gas valve seat 25 has a mixing pipe 29 that communicates with the gas passage 28. The mixing pipe 29 is inserted into the atomizer 27. Air inlets 30 are provided on both sides of the mixing pipe 29 or the atomizer 27. The lower end of the atomizer 27 is connected to the second gas nozzle 12 through a gas supply pipe. The atomizer 27 is provided with micropores or a metal mesh. Gas is injected through the micropores and fully mixed with air in the mixing pipe 29 to form a strong, rod-shaped flame.

[0038] The gas chamber 2 is divided into two independent first gas chambers 31 and second gas chambers 32. The first gas nozzle 11 is connected to the first gas chamber 31, and the second gas nozzle 12 is connected to the second gas chamber 32. They supply gas independently without interfering with each other, making the gas transmission more stable.

[0039] The operating component 5 includes two rocker arms 33 and an operating button 34. The two rocker arms 33 are oscillatingly mounted (with bosses or hinge seats, utilizing the lever principle) on the gas box 2. One end of the two rocker arms 33 is connected to the first gas nozzle 11 and the second gas nozzle 12 respectively to realize the gas flow. The other end of the rocker arms 33 extends to the bottom of the cap 35 of the ignition component 3. The ignition component 3 is a piezoelectric electronic component. A swinging component 36 is hinged on the frame 15 or the gas box 2. The swinging component 36 includes a pushing part 37 and a pressing part 38 located at both ends of the hinge point. The pushing part 37 is linked with the operating button 34. The pressing part 38 is placed above the cap 35 of the ignition component 3. Pressing the operating button 34 towards the inside of the housing can trigger the swinging component 36 to rotate, causing the ignition component 3 to discharge and the gas outlet 4 to release gas.

[0040] Two limiting members 39 are rotatably mounted on the air box 2, corresponding to the positions of the first air nozzle 11 and the second air nozzle 12 respectively. The side wall of the outer shell 1 is provided with two movable holes 40 (preferably oblong holes, but also rectangular holes). The two limiting members 39 each have a lever 41 extending out of the corresponding movable hole 40 and a blocking part 42 that restricts the reset of the corresponding rocker plate 33. In the ignition state, pushing either lever to rotate the blocking part to below one of the rocker plates can make the first air nozzle 11 or the second air nozzle 12 continuously output air. In this embodiment, a blocking plate 5 can also be provided on the rotation path of the limiting member 39. The blocking plate 5 is located on the side of the limiting member 39 away from the rocker plate 33 and a compression spring (not shown in the figure) is provided between the two. When the rocker plate opens the first air nozzle 11 or the second air nozzle 12, the blocking part 42 of the limiting member 39 will rotate into the lower part of the corresponding rocker plate 33 under the action of the compression spring. Manually pushing back the limiting member 39 can close the first air nozzle 11 or the second air nozzle 12.
