Description

Technical Field

[0001] The utility model belongs to the technical field of ignition devices, and particularly relates to an ignition mechanism of a lighter. Background Art

[0002] A direct jet lighter is also called a windproof lighter. The existing heat insulation part for ignition of most direct jet lighters is one. The several air outlets in a single heat insulation part are relatively close to each other, and the structures between these air outlets are all open, so as to ensure that an electronic ignition can ignite all the air outlets. If they are too far apart, the air outlets in other positions cannot be ignited. Therefore, the ignition area of the existing direct jet lighters is generally small and cannot meet the requirement of large-area ignition. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is how to increase the ignition area of the multi-direct jet ignition mechanism.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A single-electron multi-direct jet ignition mechanism includes a heat insulation part. The heat insulation part has a plurality of air outlets, and one of the air outlets corresponds to an ignition needle. A narrow channel is provided between the air outlets without an ignition needle on the heat insulation part and the air outlet with an ignition needle, so that the bottom fire of the air outlet with an ignition needle can pass through the channel to ignite the air outlets without an ignition needle.

[0006] Preferably, the air outlets are in a dispersed form, and there is a partition wall between two communicating air outlets. A groove communicating the two air outlets is formed on the upper surface of the partition wall.

[0007] Preferably, a cover is provided on one side of the surface of the groove of the heat insulation part in close contact with the heat insulation part. The cover is provided with a fire outlet channel corresponding to the position of the air outlet of the heat insulation part. The side of the cover facing the heat insulation part is in close contact with the surface of the heat insulation part provided with the groove, so that the groove forms a channel communicating only on both sides.

[0008] Preferably, both the heat insulation part and the cover are made of ceramic materials.

[0009] Preferably, the heat insulation part is provided with a mounting hole for the ignition needle to pass through.

[0010] Preferably, the inner wall of the fire outlet channel of the cover corresponding to the mounting hole of the heat insulation part is provided with an upper and lower through groove.

[0011] Preferably, the cover is sleeved on the heat insulation part. A stepped recessed part is provided on the outer wall of the heat insulation part on the side of the cover. The corresponding side of the cover facing the heat insulation part is provided with an outwardly protruding socket part. When the cover is connected to the heat insulation part, the socket part is sleeved at the stepped recessed part of the heat insulation part.

[0012] The beneficial effects of the present utility model are as follows: The present utility model utilizes the setting of a narrow channel between each air outlet of the heat insulation member and the air outlet of the ignition. After the main air outlet is successfully ignited, the bottom fire at the main air outlet penetrates through the channel to ignite the other air outlets. With this design, the combustion coverage area of the flame can be increased, and at the same time, the relatively independent flames at each place can be visually observed. When combined with a lighter in the shape of a rocket, it more vividly shows the state during rocket launch. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] Please refer to Figures 1 - 5, as shown in the figure, there is a lighter whose shape imitates the design of a rocket, and the flame outlet is also the tail of the rocket shape. The lighter includes a main housing 1, an outer shell 2, a fuel part 3, an igniter (not shown in the figure), and an ignition mechanism. The lighter only has an outer shell 2 shaped like a rocket, and its internal structure is not much different from that of a traditional lighter. The difference is that the ignition mechanism includes a heat insulation part 4, and the heat insulation part 4 has a plurality of air outlets 41. One of the air outlets 41 corresponds to the ignition needle. There is a narrow channel between the air outlet 41 on the heat insulation part 4 without an ignition needle and the air outlet 41 with an ignition needle, so that the bottom fire of the air outlet 41 with an ignition needle can pass through this channel to ignite the air outlet 41 without an ignition needle. The communication between each air outlet 41 is an instantaneous matter, and when the lighter is ignited, the air outlet switch is triggered first, and then the ignition switch is triggered. Therefore, when the ignition switch is triggered, the internal channel is already filled with gas. So when igniting, the flames of each air outlet 41 almost appear simultaneously. In addition, the air outlet nozzle 6 of the straight-through lighter generally includes a middle air outlet part 61 and a peripheral air outlet part 62. The middle air outlet part 61 is a straight-through and axial air outlet, and the peripheral air outlet is a radial air outlet. The outer flame appears after the radial air outlet is ignited, and the inner flame appears after the middle air outlet is ignited. Since the gas of the radial air outlet is discharged radially, it just aligns with the channel between the air outlets 41. So it can easily fill this channel and quickly ignite all the air outlets 41 when igniting. The air outlets 41 in this embodiment are of a decentralized type, and there is a partition wall between two communicating air outlets 41. A groove 42 connecting the two air outlets 41 is opened on the upper surface of the partition wall. The height of the groove 42 is preferably set to correspond to the radial air outlet of the nozzle to achieve the purpose of quick simultaneous ignition. At the same time, the relatively independent flames at each place can be intuitively seen, and combined with the lighter in the shape of a rocket, it more vividly shows the state when the rocket is launched.

[0021] In order to prevent the groove 42 from leaking air from above and causing the inability to ignite other air outlets 41, in this embodiment, a cover 5 is tightly attached to the surface of the groove 42 of the heat insulation part 4 on one side of the heat insulation part 4. The cover 5 is provided with a fire outlet channel 52 corresponding to the position of the air outlet 41 of the heat insulation part 4. The side of the cover 5 facing the heat insulation part 4 is tightly attached to the surface of the heat insulation part 4 where the groove 42 is provided, so that the groove 42 forms a channel that is only communicated on both sides. Both the heat insulation part 4 and the cover 5 are made of ceramic materials. The setting of the cover 5 makes the channel only directly communicate on both sides, and will not cause the phenomenon of a gas fault between the gases on both sides due to leakage, so that each channel can be filled with gas instantly, laying a solid foundation for igniting each air outlet 41 and ensuring that each air outlet 41 can be ignited. The heat insulation part 4 is provided with a mounting hole 43 for the ignition needle to pass through. The installation position of the ignition needle is the existing technology in the market, and will not be elaborated in detail here.

[0022] In order to facilitate the adjustment of the position of the ignition needle, in this embodiment, a vertically penetrating groove 51 is provided on the inner wall of the fire outlet channel 52 of the cover 5 corresponding to the mounting hole 43 of the heat insulation member 4. The provision of this vertically penetrating groove 51 enables both users and manufacturers to conveniently adjust the position of the ignition needle, so that the ignition needle can achieve successful ignition in one attempt or with fewer attempts.

[0023] In order to facilitate the installation of the cover 5 and the heat insulation member 4, in this embodiment, the cover 5 is sleeved on the heat insulation member 4. A stepped recess 44 is provided on the outer wall of the heat insulation member 4 on one side of the cover 5. Correspondingly, a protruding socket portion 53 is provided on the surface of the cover 5 facing the heat insulation member 4. When the cover 5 is connected to the heat insulation member 4, the socket portion 53 is sleeved at the stepped recess 44 of the heat insulation member 4. At the same time, an embedding groove 11 for the heat insulation member 4 to be embedded is provided on the main housing 1. The lower part of the heat insulation member 4 is embedded in the embedding groove 11 of the main housing 1. It further includes a pressing plate 7. A through hole corresponding to the fire outlet channel 52 of the cover 5 is provided on the pressing plate 7. The pressing plate 7 presses and fixes the cover 5 and the heat insulation member 4 on the main housing 1. Through the pressing plate 7, the two parts of the cover 5 and the heat insulation member 4 can be fixed simultaneously, thereby improving the installation efficiency and also reducing the processing efficiency.

[0024] A convex platform 54 protruding upward is provided at the edge position of the upper surface of the cover 5 corresponding to the fire outlet channel 52. A positioning hole 71 for the convex platform 54 to pass through is provided on the corresponding pressing plate 7. The convex platform 54 and the positioning hole 71 form a positioning fit. The provision of the convex platform 54 of the cover 5 reduces the influence of the flame of the fire on the pressing plate 7, so that the pressing plate 7 will not be burned out even during long-term ignition. In addition, the cooperation between the positioning hole 71 and the convex platform 54 can not only ensure the positioning installation, but also ensure the stability of the installation of the cover 5 and prevent shaking.
