Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an ignition unit, an ignition device, and a method for manufacturing the ignition unit. Background Technology

[0002] Scented candles are characterized by their fresh and pleasant fragrance. When burned, they emit a pleasant aroma and have the effects of purifying the air, soothing nerves, and eliminating odors. Scented candles generally consist of a candle body and a wick. The wick works through capillary action, transporting the fuel in the candle body to the flame for evaporation and combustion.

[0003] Existing scented candle wicks are generally made of cotton thread. To enable electronic ignition, current technology typically adds an ignition device to the cotton thread, such as a metal wire structure. The wick is ignited by a discharge at the end of this metal wire. However, when the wick is lit, the high melting point of the metal wire prevents the candle flame from burning it. After the candle burns for a while and is extinguished, the wick, which is consumed by the flame, is lowered in height. When the user attempts to ignite the candle electronically, the metal wire discharge fails to ignite the wick further away from the discharge end, resulting in ignition failure and affecting the candle's ignition reliability. Summary of the Invention

[0005] Specifically, in one aspect, the ignition unit provided in the embodiments of the present invention includes: an ignition element; an electrode portion; the electrode portion is configured to ignite the ignition element when energized, and the electrode portion burns along with the ignition element.

[0012] In one specific embodiment of the present invention, the first electrode includes a first extension segment and a second extension segment, the first extension segment being connected to the second extension segment; the second electrode includes a third extension segment and a fourth extension segment, the third extension segment being connected to the fourth extension segment; the distance between the first extension segment and the third extension segment is less than or equal to the distance between the second extension segment and the fourth extension segment.

[0013] In one specific embodiment of the present invention, the first electrode further includes a first connection end disposed on the side of the second extension away from the fourth extension.

[0014] In a specific embodiment of the present invention, the first electrode and the second electrode are arranged at intervals from each other, and the ignition member is provided with an insulating part, with the first electrode and the second electrode disposed on opposite sides of the insulating part.

[0015] In one specific embodiment of the present invention, the insulating portion is an opening provided on the ignition member, the opening extending from one end of the ignition member to the other end of the ignition member.

[0016] In one specific embodiment of the present invention, the opening is filled with an insulating medium.

[0017] In one specific embodiment of the present invention, both the first electrode and the second electrode are disposed on the surface of the ignition element.

[0018] In one specific embodiment of the present invention, the ignition element includes a first side and a second side disposed opposite to each other, the opening penetrating the first side and the second side; the first electrode is disposed on at least one of the first side and the second side; and / or the second electrode is disposed on at least one of the first side and the second side.

[0019] In one specific embodiment of the present invention, the ignition element includes a third side facing the opening and a fourth side away from the opening, the third side and the fourth side being disposed opposite to each other; a first electrode is disposed on at least one of the third side and the fourth side; and / or, a second electrode is disposed on at least one of the third side and the fourth side.

[0020] In one specific embodiment of the present invention, there are two third sides, which are arranged opposite to each other and parallel to each other, and the opening is located between the two third sides.

[0021] In one specific embodiment of the present invention, both the first electrode and the second electrode are disposed on the first side surface, and the opening is located between the first electrode and the second electrode.

[0022] In one specific embodiment of the present invention, the electrode portion is a conductive layer disposed on the ignition member, and the electrode portion is applied to the ignition member by printing, coating, pasting, deposition, or plating.

[0023] In one specific embodiment of the present invention, the conductive layer is a carbon-based conductive layer or a combustible metal conductive layer.

[0024] On the other hand, the ignition device provided in the embodiments of the present invention includes: an ignition unit as described above; a base, wherein the ignition unit is disposed on the base, and the base is electrically connected to the ignition unit.

[0028] As can be seen from the above, existing technologies typically add an ignition device to the wick's cotton thread to enable electronic ignition, such as a metal wire structure. The wick is ignited by discharge from the wire's discharge end. However, when the wick is lit, the high melting point of the metal wire prevents the candle flame from burning it. After the candle burns for a while and is extinguished, the wick remains unburned, while the wick is consumed, causing it to drop in height. This results in the wick's height being lower than the height of the wire's discharge end. When the user attempts to ignite the wick electronically again, the wire's discharge cannot reach the wick, which is further away from the wire's discharge end, leading to ignition failure. In this embodiment of the invention, the electrode portion is configured such that when energized, the electrode portion can burn along with the ignition element, and the electrode portion can be consumed along with the ignition element. The discharge ignition end in the electrode portion can also be consumed along with the ignition element, so that the height of the discharge ignition end in the electrode portion is always consistent with the height of the ignition element, and the electrode portion can continuously ignite the ignition element, thus ensuring the ignition reliability of the ignition unit.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, and bottom) in the embodiments of this invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, the term "vertical" in the embodiments and claims refers to an angle of 90° between two components or a deviation of -5° to +5°, and the term "parallel" refers to an angle of 0° between two components or a deviation of -5° to +5°.

[0050] In the embodiments of this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0051] In the embodiments of this application, the ignition device may be an ignition device on a candle device, and the candle device may include, for example, a scented candle or a general lighting candle and an ignition device. The scented candle can emit a pleasant fragrance when burning, and has the effects of purifying the air, soothing nerves, and eliminating odors. In this embodiment, the ignition unit is an ignition device on a scented candle as an example for description.

[0052] [First Embodiment]

[0053] See Figure 1 This invention provides an ignition unit 1, which can be used as the ignition wick of a candle, i.e., the wax wick. The ignition unit 1 includes, for example, an ignition element 10 and an electrode portion 20.

[0054] Specifically, the electrode portion 20 is configured to ignite the ignition element 10 when energized, and the electrode portion 20 burns along with the ignition element 10, meaning that the electrode portion 20 can be consumed as the ignition element 10 is consumed. The discharge ignition principle of the electrode portion 20 is as follows: electrode ignition is a method of placing current in the electrode gap to form an electric arc, which converts electrical energy into heat energy to generate high temperature and high pressure, thereby initiating ignition. In this application, after being energized, the discharge end of the electrode portion 20 generates a high-temperature electric arc, and a high-temperature electric arc is generated at the closest point of the spacing between the conductive electrodes spaced apart in the electrode portion 20. Existing candle devices consist of a wick and an electronic ignition mechanism. The wick is made of woven cotton thread, while the electronic ignition mechanism is made of a metal wire, such as copper wire. Copper wire has a melting point of over 1000 degrees Celsius. The discharge at the end of the metal wire ignites the wick. While the wick is burning, the melting point of the metal wire in the electronic ignition mechanism is very high, but the burning temperature of the candle wick is insufficient to melt the wire. Therefore, after the wick burns, the metal wire is not completely melted and consumed. This results in the height of the discharge end of the metal wire after burning being higher than the height of the consumed wick. When the electrical terminal discharges for ignition, it may fail to ignite the wick of the cotton thread. In addition, due to the height difference, the upper part of the metal wire may lose the support of the wick, causing the metal wire to fall together and resulting in a short circuit. This short circuit will prevent electronic ignition, thus reducing the reliability of the candle's ignition. Therefore, in order to improve the reliability of the candle's ignition, this application is configured with an electrode part 20 that is consumed as the igniter 10 burns, thereby preventing the ignition unit 1 from experiencing the problems found in the prior art and improving the ignition reliability of the ignition unit.

[0055] The electrode portion 20 has a discharge end 201, the position of which changes as the electrode portion 20 burns. In this embodiment, the discharge end 201 is the top end of the electrode portion 20. When the igniter 10 is burned, since the electrode portion 20 can burn along with the igniter 10, the discharge end 201 of the electrode portion 20 also changes accordingly. Figure 5B As shown, after the ignition unit 1 is consumed by combustion, the position of the discharge end 201 of the electrode 20 also changes. This application is configured in this way so that the discharge end 201 of the electrode 20 is always at the top of the ignition element 10, thereby effectively igniting the ignition element 10 a second time. This ensures that after the ignition element 10 has been consumed by combustion for a period of time, the electrode 20 can still ignite the ignition element 10 a second time, improving the reliability of the secondary ignition of the ignition unit 1. This prevents the phenomenon in the prior art where secondary ignition fails to ignite the ignition element 10.

[0056] In the first preferred embodiment of this example, as Figures 1-5B As shown, the electrode section 20 includes, for example, a first electrode 21 and a second electrode 22.

[0057] In this embodiment, at least one of the first electrode 21 and the second electrode 22 is disposed on the ignition element 10; or both the first electrode 21 and the second electrode 22 are disposed at a distance from the ignition element 10. That is, at least one of the first electrode 21 and the second electrode 22 is disposed on the ignition element 10, or both the first electrode 21 and the second electrode 22 are disposed on the ignition element 10, or both the first electrode 21 and the second electrode 22 are disposed at a distance from the ignition element 10, as long as it can be ensured that the first electrode 21 and the second electrode 22 can burn along with the ignition element 10. This application does not limit the relative positional relationship between the first electrode 21 and the second electrode 22 and the ignition element 10. In this embodiment, the first electrode 21 and the second electrode 22 can be formed by a conductive layer disposed on the ignition element 10. The conductive layer is, for example, a graphite conductive layer. The graphite conductive layer is used to facilitate the printing of the electrode portion on the ignition element 10 and to facilitate the ignition and combustion of the first electrode 21 and the second electrode 22 by the ignition element 10 after ignition. In this embodiment, the first electrode 21 and the second electrode 22 are, for example, graphite electrode sheets. The first electrode 21 may be, for example, an anode electrode sheet, and the second electrode 22 may be, for example, a cathode electrode sheet. In other embodiments, the first electrode 21 may be, for example, a cathode electrode sheet, and the second electrode 22 may be, for example, an anode electrode sheet. The first electrode 21 may be a cathode electrode or an anode electrode, and the second electrode 22 may be an anode electrode or a cathode electrode, depending on the actual situation. As long as the first electrode 21 and the second electrode 22 are opposite electrodes, no specific limitation is made here.

[0058] The ignition element 10 is an ignition source made of flammable material, but it also has a certain degree of hardness. The first electrode 21 and the second electrode 22 are also electrode sheets made of flammable material. The electrodes formed by placing the conductive layer on the ignition source can also be consumed and reduced along with the combustion of the ignition element 10. Existing candle wicks are typically made of woven cotton thread, which is generally quite soft. After burning and then extinguishing, the cotton thread collapses to one side of the candle wax instead of remaining in one position. This alters the relative position between the cotton thread and the metal wire. For example, before burning, the tip of the cotton thread is connected to the tip of the metal wire, but as the burning progresses, the tip of the cotton thread diminishes, causing the metal wire to lose its support and shifting their relative positions. This can lead to a short circuit between the anode and cathode of the metal wire, preventing ignition. Furthermore, because cotton thread is generally soft, controlling the spacing between the anode and cathode of the metal wire woven into it is difficult, making it impossible to ensure that the discharge is controlled at the tip of the metal wire during arc ignition, further increasing the unreliability of ignition. In contrast, the igniter in this application, due to its rigidity, does not collapse to one side after burning and remains upright on the candle wax. This means that the relative position between the conductive layer and the igniter does not change during burning. Secondly, the first electrode 21 and the second electrode 22 of this application can be consumed together with the igniter 10. In the prior art, electronic ignition can also be achieved by weaving metal wire and cotton thread together to form a wick. However, since the melting point of the added metal wire is relatively high, the temperature of the candle burning will not reach the melting point of the metal wire. Therefore, the cotton thread will be consumed by burning, but the metal wire will not be consumed. Since the metal wire has a high melting point, it will continue to discharge in places where it is not needed to burn. Discharging in places where it is not needed to burn will result in the cotton thread not being able to be ignited, thus causing the phenomenon of failure to ignite.

[0059] like Figures 1-2 As shown, the ignition element 10 is provided with an insulating portion 11; the first electrode 21 and the second electrode 22 are arranged at intervals, and the first electrode 21 and the second electrode 22 are located on opposite sides of the insulating portion 11. The first electrode 21 and the second electrode 22 are arranged at intervals to create a gap between the first electrode 21 and the second electrode 22. If there is no gap between the first electrode 21 and the second electrode 22, a short circuit will occur, thus preventing ignition.

[0060] like Figure 3As shown, the first electrode 21 includes a first end 214 and a second end 215, which are disposed opposite to each other. In this embodiment, the first end 214 may be, for example, the upper end of the first electrode 21, and the second end 215 may be, for example, the lower end of the first electrode 21. The second electrode 22 includes a third end 224 and a fourth end 225, which are disposed opposite to each other. In this embodiment, the third end 224 may be, for example, the upper end of the second electrode 22, and the fourth end 225 may be, for example, the lower end of the first electrode 21. The second end 215 and the fourth end 225 are insulated from each other. When energized, the first electrode 21 and the second electrode 22 always discharge at the first end 214 and the third end 224, that is, the discharge end between the first electrode 21 and the second electrode 22 can remain at the upper end.

[0061] Specifically, such as Figure 3 As shown, in this embodiment, the structural composition of the first electrode 21 and the second electrode 22 is different from that in other embodiments. In this embodiment, the structure of both the first electrode 21 and the second electrode 22 can be composed of an upper end and a lower end. In other embodiments, the first electrode 21 and the second electrode 22 can also be composed of an upper end, a middle section, and a lower end. When the structure of the first electrode 21 and the second electrode 22 is composed of an upper end and a lower end, an insulating structure 23 is provided on the second end 215; and / or, an insulating structure 23 is provided on the fourth end 225. As long as insulation can be maintained between the second end 215 and the fourth end 225, the discharge end between the first electrode 21 and the second electrode 22 can be maintained at the upper end. When the first electrode 21 and the second electrode 22 are composed of an upper end, a middle section, and a lower end, their structure is different from that of an electrode structure composed of an upper end and a lower end. See the specific references below. Figure 4 .

[0062] In a preferred embodiment of this example, such as Figure 1 , Figure 2 and Figure 4 As shown, the insulating part 11 is an opening 111 provided on the ignition member 10. The opening 111 extends from one end of the ignition member 10 to the other end of the ignition member 10. One end of the ignition member 10 refers to the end in the longitudinal direction, which extends from one end of the ignition member 10 to the other end in the longitudinal direction. The depth of the opening 111 can be adjusted according to the actual situation, and is not limited here. The opening 111 is filled with an insulating medium, such as air or an inert gas.

[0063] When the first electrode 21 and the second electrode 22 are disposed on the surface of the ignition element 10, the first electrode 21 and the second electrode 22 can burn more easily. The ignition element 10, such as wood chips, will carbonize after burning. The carbonized part will form a conductor, which will cause the first electrode 21 and the second electrode 22 to be electrically connected, resulting in a short circuit between the first electrode 21 and the second electrode 22. Ultimately, this will prevent the generation of a high-temperature electric arc. Therefore, the opening 111 is provided in the ignition element 10 to separate the first electrode 21 and the second electrode 22, avoiding the short circuit caused by the conductive connection between the first electrode 21 and the second electrode 22. This allows the first electrode 21 and the second electrode 22 to continuously perform high-temperature arc discharge and ignition functions. Secondly, the opening 111 can also prevent the ignition element 10 from carbonizing and forming a conductive structure after combustion. The conductive structure will cause the first electrode 21 and the second electrode 22 to form an electrical connection, which will cause a short circuit between the first electrode 21 and the second electrode 22. This can prevent the short circuit caused by the conductive connection between the first electrode 21 and the second electrode 22.

[0064] The first electrode 21 includes a first extension segment 211 and a second extension segment 212, with the first extension segment 211 connected to the second extension segment 212. The second electrode 22 includes a third extension segment 221 and a fourth extension segment 222, with the third extension segment 221 connected to the fourth extension segment 222. The distance between the first extension segment 211 and the third extension segment 221 is less than or equal to the distance between the second extension segment 212 and the fourth extension segment 222. When the first extension segment 211 and the second extension segment 212 are both integrally extended straight segments, and the third extension segment 221 and the fourth extension segment 221 are also both integrally extended straight segments, the distance between the first extension segment 211 and the third extension segment 221 is equal to the distance between the second extension segment 212 and the fourth extension segment 222. When the distance between the first extension segment 211 and the third extension segment 221 is less than or equal to the distance between the second extension segment 212 and the fourth extension segment 222, the discharge ends of the first electrode 21 and the second electrode 22 are always at the top position. This is because when the first electrode 21 and the second electrode 22 discharge, they generate a high-temperature arc through high voltage, and will find the point with the closest distance between the first electrode 21 and the second electrode 22 to discharge. The distance relationship is set so that the first electrode 21 and the second electrode 22 can always maintain the top discharge.

[0065] In this embodiment, the first extension segment 211 is angled relative to the second extension segment 212. Specifically, the first extension segment 211 is tilted or bent relative to the second extension segment 212, meaning the first extension segment 211 is closer to the insulating part 11 than the second extension segment 212. Simultaneously, a certain distance must be maintained between the first extension segment 211 and the second extension segment 212. This is because the high voltage generates a high-temperature arc, which will discharge at the point closest to the distance between the first electrode 21 and the second electrode 22. By tilting or bending the extension segment, the point closest to the distance between the first electrode 21 and the second electrode 22 is positioned at the tip when not ignited, thus ensuring tip discharge ignition and improving ignition reliability. In other embodiments, the third extension segment 221 on the second electrode 22 may be set at an angle relative to the fourth extension segment 222, or the first extension segment 211 may be set at an angle relative to the second extension segment 212, and the third extension segment 221 may be set at an angle relative to the fourth extension segment 222. That is, only the top end of the first electrode 21 or the top end of the second electrode 22 may be tilted or bent toward the opening 111, or both the top ends of the first electrode 21 and the second electrode 22 may be tilted or bent toward the opening 111. At the same time, the top ends of the first electrode 21 and the second electrode 22 may be spaced apart to achieve discharge at the top ends of the first electrode 21 and the second electrode 22. In this embodiment, at least one of the top ends of the first electrode 21 and the second electrode 22 may be tilted or bent toward the opening 111. The specific setting may vary depending on the actual situation and is not limited here.

[0066] like Figures 1-3 As shown, the ignition element 10 is an insulating material when not burning, and forms a conductive structure 13 after burning. The ignition element can be, for example, a piece of wood. After burning, the ignition element 10 forms a conductive structure 13, which can form an electrical connection with the electrode part 20, so that the discharge end 201 of the electrode part 20 can always be kept at the top.

[0067] like Figure 3As shown, the ignition element 10 also includes a blank area 12, which is the area outside the electrode portion on the ignition element 10, that is, the blank area 12 is the area where the electrode portion 20 is not located. In this embodiment, the blank area 12 is located on one side of the second extension segment 212 and / or one side of the fourth extension segment 222, and the blank area 12 is closer to the insulating portion 11 than the second extension segment 212 and / or the fourth extension segment 222. In this application, the blank area 12 is the area on a straight segment closer to the insulating portion where no electrode is located. The blank area 12 is set on the straight segment so that when the igniter 10 is not burning, the first side 101 on the left and right sides of the insulating part 11 can remain parallel, and the distance between the second extension 212 and the fourth extension 222 can be greater than the distance between the first extension 211 and the third extension 221. Thus, when the igniter is burning, the first extension end 211 and the third extension 221 are the top discharge areas through the action of the high temperature electric arc. Thus, the igniter 10 can be ignited first, and the first extension 211 and the third extension 221 can be consumed first through the combustion of the igniter 10.

[0068] The electrode portion 20 is a conductive layer disposed on the ignition element 10. The electrode portion 20 can be applied to the ignition element 10 by means of printing, coating, pasting, deposition, or coating, for example. By applying the conductive layer to the ignition element 10 by printing, coating, pasting, deposition, or coating, the conductive layer can be quickly applied to the ignition element 10 through processes such as printing, which can speed up the manufacturing process and production flow of the ignition unit 1 and reduce production time.

[0069] The conductive layer can burn along with the igniter 10; and / or the igniter 10 is made of plant fiber material. The igniter 10 can be, for example, wood chips. In this embodiment, the igniter 10 can be made of plant fiber material, such as wood chips, and the conductive layer is a carbon-based conductive layer or a combustible metal conductive layer, wherein the carbon-based conductive layer is, for example, a graphite conductive layer. This arrangement is so that the conductive layer can burn along with the igniter 10. When the wood chips burn, the blank area 12 without a conductive layer will burn and carbonize. The blank area 12 formed after the wood chips burn will carbonize, and the carbonized area will have conductive properties, such as a conductive structure 13. The conductive structure 13 can conduct electricity and can be electrically connected to the first electrode 21 and / or the second electrode 22 on the electrode portion 20. Figures 5A-5BAs shown, after the first extension segment 211 and the third extension segment 221 are consumed by combustion, the position of the discharge terminal 201 of the electrode portion 20 changes and is located on the second extension segment 212 and the fourth extension segment 222. Since the distance between the second extension segment 212 and the fourth extension segment 222 is the same, it is possible that when the igniter 10 is ignited, it may not start burning at the top of the second extension segment 212 and the fourth extension segment 222, or it may burn on any segment of the second extension segment 212 and the fourth extension segment 222. This would be a poor user experience. Therefore, through the combustion process, the blank area 12 near the insulating portion 11 will form a conductive structure 13 after combustion. Since the conductive structure 13 exists at the top of the second extension segment 212 and the fourth extension segment 222, the distance between them will be shorter than the distance between other segments of the second extension segment 212 and the fourth extension segment 222. This ensures that the igniter 10 burns from top to bottom and not in any random place. The graphite conductive layer can burn along with the igniter 10 because if the electrodes on the igniter are not burned off, it will continue to discharge in places where it is not needed. Discharging in places where it is not needed will not ignite the igniter. Therefore, the conductive layer needs to burn along with the igniter 10.

[0070] In this embodiment, when the conductive layer is disposed on the ignition element 10, the shapes of the first electrode 21 and the second electrode 22 remain unchanged. However, in the prior art, candle wicks are made of cotton thread. If the conductive layer is disposed on the cotton thread, the weak adhesion of the cotton thread causes the shape of the conductive layer printed on the cotton thread to expand instead of maintaining its original shape. As described in this application, a certain distance needs to be maintained between the first electrode 21 and the second electrode 22 to satisfy the conventional phenomenon of candle burning from top to bottom. If the shape changes, the shortest distance between the first electrode 21 and the second electrode 22 may not be on the first extension segment 211 and the third extension segment 221, thus failing to satisfy the tip discharge between the first electrode 21 and the second electrode 22. This would lead to unpredictable discharge positions and reduce the reliability of candle ignition. Therefore, this application ensures that the shapes of the first electrode 21 and the second electrode 22 remain unchanged when the conductive layer is disposed on the ignition element 10, ensuring that the shortest distance between the tips of the first electrode 21 and the second electrode 22 is met during ignition, thus satisfying the requirement for tip ignition and ensuring reliable ignition.

[0071] Furthermore, such as Figures 1-2 As shown, the ignition element 10 may include, for example, a first side 101, a second side 102, a third side 103, and a fourth side 104. In this embodiment, the example is given with two sides for each ignition element. Figures 1-2 As shown, two third side surfaces 103 are respectively disposed on both sides facing the opening 111. One third side surface 103 is disposed, for example, on the left side of the opening 111, and the other third side surface 103 is disposed, for example, on the right side of the opening 111. The two third side surfaces 103 are arranged opposite to each other and parallel to each other. The fourth side surface 104 is disposed opposite to the third side surface 103 and away from the insulating part 11. The first side surface 101 and the second side surface 102 are disposed between the third side surface 103 and the fourth side surface 104, and are adjacent to the third side surface 103 and the fourth side surface 104. The first side surface 101 and the second side surface 102 are arranged opposite to each other. In this embodiment, there is one first electrode 21 and one second electrode 22. The first electrode 21 can be disposed on any one of the first side surface 101, the second side surface 102, the third side surface 103, and the fourth side surface 104 on the left side of the insulating part 11; the second electrode 22 can be disposed on any one of the first side surface 101, the second side surface 102, the third side surface 103, and the fourth side surface 104 on the right side of the insulating part 11. That is, in this application, the first electrode 21 and the second electrode 22 can be arbitrarily disposed on any side of the ignition member 10, and no specific limitation is made here. In other embodiments, there are multiple first electrodes 21 and second electrodes 22. The multiple first electrodes 21 can be disposed on any one or more of the first side 101, second side 102, third side 103, and fourth side 104 on the left side of the insulating part 11, and the second electrodes 22 can be disposed on any one or more of the first side 101, second side 102, third side 103, and fourth side 104 on the right side of the insulating part 11. The number of first electrodes 21 and second electrodes 22 in this application is also not limited; one or more can be provided according to actual conditions, and no specific limitation is made here. In other embodiments, the ignition element 10 may include only two sides, namely only a first side 101 and a second side 102. The first side 101 may be the front of the ignition element, and the second side 102 may be the back of the ignition element. That is, the ignition element 10 may be an arc-shaped structure, and the first electrode 21 and the second electrode 24 may be disposed on either the front or back of the ignition element 10. In other words, the positions of the first electrode 21 and the second electrode 24 on the ignition element can also be correspondingly set according to the shape of the ignition element, and are not specifically limited here.

[0072] In this embodiment, both the first electrode 21 and the second electrode 22 are disposed on the first side surface 101, and the opening 111 is located between the first electrode 21 and the second electrode 22. By disposing both the first electrode 21 and the second electrode 22 on the first side surface 101, it is convenient to print and manufacture the first electrode 21 and the second electrode 22 during the fabrication of the ignition unit 1. Of course, in other embodiments, the first electrode 21 and the second electrode 22 can be disposed on different sides. Specific adjustments can be made according to actual circumstances, and no particular limitation is imposed here.

[0073] In this embodiment, the two third side surfaces 103 are arranged opposite and parallel, and the insulating part 11 can be disposed between the two third side surfaces 103, that is, the opening 111 is disposed between the two third side surfaces 103. Furthermore, the third side surfaces 103 can also be parallel to the fourth side surface 104. The parallel arrangement of the two third side surfaces 103 is to control the size of the opening 111, ensuring that the size of the opening 111 remains consistent, and that the insulation distance between the two third side surfaces 103 remains consistent, thus improving the reliability of ignition. Secondly, the parallel arrangement of the third side surfaces 103 and the fourth side surface 104 ensures that when the igniter 10 is burning, the flame size generated by the first electrode 21 and the second electrode 22 remains consistent, ensuring that the flame size seen by the user is consistent, thus improving the user experience.

[0074] In a preferred embodiment of this example, such as Figure 4 As shown, the first electrode 21 further includes a first connecting end 213 disposed along the side of the second extension 212 away from the fourth extension end 222, that is, the first connecting end 213 can be disposed on the first electrode 22 along the side of the second extension 212 away from the insulating part 11. The second electrode 22 further includes a second connecting end 223 disposed along the side of the fourth extension 222 away from the insulating part 11. In this embodiment, the width of the first connecting end 213 is greater than the width of the second extension 212. This is to increase the contact area of ​​the first connecting end 213, thereby increasing the contact area between the ignition unit and the base when assembled onto the base. Of course, the second electrode 21 may also include a second connecting end 223 disposed along the side of the fourth extension 222 away from the insulating part 11. The structure of the second connecting end 223 can be specifically referred to as the structure of the first connecting end 213, and will not be described again here.

[0075] [Second Embodiment]

[0076] like Figure 6 As shown, this embodiment provides an ignition device 50, which includes, for example, an ignition unit 1 and a base 51.

[0077] The ignition unit 1 is the ignition unit 1 described in the first embodiment above. Its specific structure can be referred to in the first embodiment, and will not be described in detail here.

[0078] The base 51 is electrically connected to the ignition unit 1, and the ignition unit 1 can be fixedly connected to the base 51.

[0079] Furthermore, the base 51 is provided with a conductive end 52. The conductive end is, for example, the snap-fit ​​socket shown in Figure 5, or a contact terminal, etc., depending on the actual situation. The specific configuration is not limited here.

[0080] In this embodiment, when there is one ignition unit 1, it is snapped onto the conductive end 52 to form a fixed connection and electrical connection with the base. In other embodiments, when there are at least two ignition units, for example, two ignition units 1 can be attached together before being snapped onto the conductive end 52. When there are three or four ignition units, they can also be attached together before being installed onto the base 51 to form an ignition device 50. Alternatively, two ignition units 1 can be spaced apart and snapped onto the conductive end 52, for example, by setting an air layer or other spacer between the two ignition units to make the two ignition units 1 spaced apart. When there are three or four ignition units, they can also be spaced apart before being installed onto the base 51 to form an ignition device 50.

[0081] [Third Embodiment]

[0082] like Figure 7 As shown, this embodiment provides a method for manufacturing an ignition unit, which includes the following steps:

[0083] S101, Provide ignition components;

[0084] S102. A conductive layer is disposed on the ignition element to obtain the ignition unit.

[0085] In step S101, the specific steps for providing the ignition element are as follows: Plant fiber sheets are cut to a thickness of 0.5mm-1mm to obtain the ignition element; of course, other materials can also be cut in other embodiments, such as wood chips with a certain degree of hardness. Having a certain degree of hardness facilitates assembly and printing. Secondly, the material must have a certain degree of absorbency, such as being able to absorb the wax residue after the candle wax has melted. During combustion, by absorbing the candle wax, the wax residue can be consumed, allowing the ignition element to continue burning. Furthermore, the material of the ignition element 10 in this application also needs to meet the characteristic of being combustible.

[0086] In step S102, as Figure 7 As shown, the conductive layer is a carbon-based conductive layer or a combustible metal conductive layer, and the carbon-based conductive layer is a graphite conductive layer. Step S102 may specifically include the following steps:

[0087] S1021, Provides a conductive layer;

[0088] S1022, A conductive layer is printed onto the ignition element, and at least one pair of first electrodes and second electrodes are formed on the ignition element.

[0089] like Figure 4 , Figure 11A and Figure 11B As shown, a graphite conductive layer is selected from the conductive layers. This graphite conductive layer can then be configured with at least one pair of first and second electrodes according to a preset shape. This preset shape includes, for example, a first extension segment, a second extension segment, a first connecting end, a third extension segment, a fourth extension segment, and a second connecting end. The width of the first connecting end is greater than the width of the first or second extension segment, and the width of the second connecting end is greater than the width of the third or fourth extension segment. In this application, the first and third extension segments can be inclined towards the insulating portion, and the first and second electrodes are printed as a pair. The printing process can refer to existing printing processes; for example, the required electrode shape can be printed on a mold first, and then the shape of at least one pair of electrodes can be rolled onto an ignition element, such as a wood chip. The printed ignition element is then obtained. By rolling the shapes of multiple pairs of electrodes onto a wood chip, the shapes of the first and second electrodes remain unchanged. The wood chip, due to its strong adsorption properties, can adhere the conductive layer to it, ensuring the printed pattern remains consistent. However, in existing technologies using cotton thread as a wick, if the conductive layer is printed onto the thread, its poor adsorption properties cause the printed conductive layer to expand instead of maintaining its original shape. This results in the inability to maintain the required spacing, failing to meet the conditions for tip discharge. Consequently, the igniter cannot ignite at the tip, reducing ignition reliability.

[0090] like Figure 9 As shown, the ignition unit includes at least one ignition unit, and the method further includes, for example:

[0091] S103. Cut the at least one ignition unit obtained in step S102.

[0092] Among them, such as Figure 10 As shown, step S103 may specifically include the following steps:

[0093] S1031. Cut the third side of the printed igniter, and then cut the fourth side opposite to the third side.

[0094] S1032. Cut another third side opposite to the third side of the igniter to form the insulating part of the igniter, and then cut another fourth side opposite to the third side to obtain the ignition unit; wherein, the graphite conductive layer is printed on the first side adjacent to the third side of the igniter to form the first electrode and the second electrode.

[0095] like Figure 4 , Figure 11A and Figure 11B As shown, the printed ignition element needs to be cut to obtain the required ignition unit. First, it can be cut according to the third side of the ignition element to form a third side, such as the third side 103 on the left side of the insulating part 11. Then, the fourth side 104 on the left side of the insulating part 11 opposite to the third side 103 is cut. After cutting out part of the shape of the first electrode, the third side 103 on the right side of the insulating part, that is, part of the shape of the second electrode, is cut. After cutting the two third sides 103, an insulating opening will be formed in the middle. At this time, the fourth side 104 on the right side of the insulating part 11 is cut to obtain a complete ignition unit. Since the printing process can be performed on one side of the plant fiber sheet, the first electrode 21 and the second electrode 22 can be formed on the first side 101 or the second side 102 of the ignition element. At the same time, during cutting, the width of the first connecting end 213 and the second connecting end 223 is cut to be greater than the width of the second extension segment 212 and the fourth extension segment 222, and then the ignition unit 1 is obtained. The ignition unit obtained after cutting is the ignition unit required in the first embodiment. The cutting process in this application can employ laser cutting, which provides more accurate cutting. In this embodiment, since one or more pairs of first and second electrodes can be printed during printing, when multiple pairs of first and second electrodes are printed, multiple ignition units can be obtained through multiple cuts during cutting. That is, the ignition unit can be cut in a single cut or multiple cuts depending on the number of first and second electrodes printed. Specific details are not limited here.

[0096] The ignition unit 1 obtained by the manufacturing method of this application is simpler than the candles obtained by the weaving process in the prior art. It only requires setting a preset shape on the mold, then printing the conductive layer onto the ignition part, and finally obtaining the ignition unit by laser cutting. It can be mass-produced and reduces production time.

[0097] [Fourth Embodiment]

[0098] like Figure 12 As shown, this embodiment of the invention provides a method for manufacturing an ignition device, comprising the following steps:

[0099] S201. An ignition unit is obtained through the method of manufacturing an ignition unit;

[0100] S202. At least one of the aforementioned ignition units is installed and electrically connected to the base to obtain an ignition device.

[0101] In this embodiment, the method for manufacturing the ignition unit can refer to the method for manufacturing the ignition unit described in the third embodiment, and will not be repeated here.

[0102] The obtained ignition unit is then placed on the base 51 to form an ignition device. When there is one ignition unit 1, it is snapped onto the base 51 to form a fixed connection and electrical connection with the base. In other embodiments, when there are at least two ignition units, for example, two ignition units can be attached together or spaced apart before being snapped onto the conductive end. When there are three or four ignition units, they can also be attached together or spaced apart before being installed onto the base 51 to form an ignition device.
