Description

Technical Field

[0001] This utility model relates to the field of lighter technology, and in particular to a lighter with automatic flame adjustment for high-altitude areas. Background Technology

[0002] As a convenient ignition tool, lighters are widely used in various scenarios such as daily life, outdoor work, and camping adventures. Their core structure usually consists of an ignition mechanism and a gas tank. In normal use, the user triggers the ignition mechanism by pressing the ignition button. The spark emitted by the ignition mechanism is directed towards the gas area, igniting the gas released from the fuel chamber, thereby achieving the ignition function. These lighters have become a common item in people's daily lives due to their simple structure, convenient operation, and low cost.

[0003] However, in high-altitude areas (such as plateaus and mountains with an altitude exceeding 1500 meters), conventional lighters often fail to function properly. The core issue lies in the impact of the special climatic conditions at high altitudes on gas combustion. At high altitudes, atmospheric pressure is low, air is thin, and oxygen content is only 60%-80% of that in plains areas. Furthermore, the external air pressure decreases further with increasing altitude. Conventional lighters have fixed gas output and flame size designs and cannot adaptively adjust to changes in external air pressure and oxygen concentration. When the external air pressure is too low, the gas flow rate released from the fuel chamber increases, leading to an imbalance in the mixing ratio with air. This can result in an excessively strong flame, a flickering and unstable flame, or even flameout due to incomplete combustion. In extreme high-altitude environments, some lighters may even fail to ignite or extinguish rapidly after ignition, failing to meet basic ignition requirements.

[0004] Therefore, it is necessary to provide a lighter with automatic flame adjustment for high-altitude areas to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a lighter with automatic flame adjustment for high-altitude areas, which solves the problem that conventional lighters, in high-altitude and low-pressure environments, have a fixed gas output, resulting in an overly strong, flickering, or extinguished flame, and are unable to adaptively adjust.

[0020] This invention provides a lighter with automatic flame adjustment for high-altitude areas. Through the coordinated structure of a pressing component, a transmission assembly, and an adjustment assembly, in high-altitude, low-pressure environments, if the flame is too strong or flickering, the pressing force can be appropriately reduced, decreasing the upward movement of the gas guide and narrowing the gap between the conical groove and the conical block, thus reducing the gas output and allowing the gas to form a suitable mixture with the rarefied air, preventing an overly strong flame. If the flame is weak or extinguished, the pressing force can be increased, pushing the gas guide further upward and widening the gap to increase gas output, ensuring stable combustion. In this way, the lighter's flame can be adaptively adjusted according to specific usage conditions, meeting the basic ignition needs of high-altitude areas. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a lighter with automatic flame adjustment for high-altitude areas provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional structure. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown.

[0031] A lighter with automatic flame adjustment for high-altitude areas includes: a housing 1, wherein the housing 1 has a fuel chamber 11 and a mounting chamber 12 inside;

[0032] Pressing member 2, which is slidably connected to the top of the inner side of the housing 11;

[0033] Protective shell 3, which is fixedly installed on the top of the shell 1;

[0034] Electronic ignition assembly 4, the electronic ignition assembly 4 is disposed on the inner side of the mounting cavity 12, and the top of the electronic ignition assembly 4 abuts against the top of the inner side of the pressing member 2;

[0035] Transmission assembly 5, wherein the transmission assembly 5 is disposed on the inner side of the mounting cavity 12;

[0036] An adjustment component 6 is disposed on the inner side of the mounting cavity 12. The adjustment component 6 includes an air guide 61, a conical groove 62, a conical block 63, a mounting rod 64, an air guide channel 65, and a burner 67. The bottom of the outer side of the air guide 61 is slidably connected to the inside of the top of the mounting cavity 12. The conical groove 62 is opened at the bottom of the air guide 61. The conical block 63 is disposed on the inner side of the conical groove 62. The mounting rod 64 is fixedly installed at the bottom of the conical block 63 and is also fixedly installed on the inner side of the fuel chamber 11. The air guide channel 65 is opened inside the air guide 61. The burner 67 is fixedly installed at the top of the air guide 61.

[0037] The fuel chamber 11 is used to store gas, and its inner wall is specially sealed to prevent gas leakage; the installation chamber 12 provides installation space and operating location for other functional components.

[0038] The pressing part 2 is installed on the top of the inner side of the housing 1 by means of a sliding connection. It can slide up and down along the inside of the housing under the action of the user's pressing pressure. This connection method not only ensures the smooth movement of the pressing part 2, but also prevents it from falling off to a certain extent.

[0039] The protective shell 3 is made of high-temperature resistant material to withstand the high temperatures generated during ignition.

[0040] The protective shell 3 has a through groove 31 on its top, and the through groove 31 is located on the top of the burner 67.

[0041] The output end of the electronic ignition assembly 4 is equipped with a conductive wire 41, and a fixing plate 42 is fixedly installed on the outer side of the conductive wire 41. The top of the fixing plate 42 is fixedly installed on the top of the inner side of the protective shell 3.

[0042] The electronic ignition assembly 4 transmits high voltage electricity to the ignition position through the conductive wire 41 to generate a spark to ignite the gas. A fixing plate 42 is fixedly installed on the outer side of the conductive wire 41. The top of the fixing plate 42 is fixedly connected to the top of the inner side of the protective shell 3. This design can ensure that the conductive wire 41 is stable inside the lighter and avoid the inability to ignite the fuel due to vibration or other reasons.

[0043] The transmission assembly 5 includes a rotating shaft 51 and a transmission plate 52. The rotating shaft 51 is fixedly installed on the inner side of the mounting cavity 12, and the transmission plate 52 is rotatably connected to the outer side of the rotating shaft 51. The two ends of the transmission plate 52 abut against the bottom of the pressing member 2 and the air guide member 61, respectively.

[0044] The adjustment assembly 6 also includes an elastic telescopic tube 66, which is fixedly installed on the outer side of the air guide 61, and the bottom of the elastic telescopic tube 66 is fixedly installed on the top of the mounting cavity 12.

[0045] The elastic telescopic tube 66 is fixedly installed on the outer side of the gas guide 61, and its bottom is fixedly connected to the top of the mounting cavity 12. When the pressing part 2 is released, the elastic force of the elastic telescopic tube 66 will drive the gas guide 61 to reset and shut off the gas output. At the same time, when adjusting the flame size, the elastic telescopic tube 66 can also play a certain buffering role, making the movement of the gas guide 61 more stable.

[0046] The working principle of the lighter with automatic flame adjustment for high-altitude areas provided by this utility model is as follows:

[0047] During ignition, pressing the pressing element 2 causes it to slide downwards and trigger the electronic ignition assembly 4. The electronic ignition assembly 4 releases a high-voltage spark through the conductive wire 41. Simultaneously, the pressing element 2 presses one end of the transmission plate 52, causing the transmission plate 52 to rotate around the shaft 51. The other end pushes the gas guide 61 upwards, further opening the gap between the conical groove 62 and the conical block 63, ensuring that the gas is smoothly discharged and ignited by the spark. The flame is ejected from the through groove 31 of the protective shell 3, completing the ignition. After releasing the pressing element 2, the elastic telescopic tube 66 drives the gas guide 61 to reset, and the transmission plate 52 and the pressing element 2 return to their initial positions, shutting off the gas output.

[0048] When it is necessary to adjust the fuel injection flow rate, the pressing member 2 can be pressed down, thereby causing the air guide member 61 to continue to move upward, thereby increasing the gap between the conical groove 62 and the conical block 63, thereby adjusting the air output and the flame.

[0049] Compared with related technologies, the lighter with automatic flame adjustment for high-altitude areas provided by this utility model has the following beneficial effects:

[0050] Through the coordinated structure of the pressing component 2, transmission component 5, and adjustment component 6, in high-altitude, low-pressure environments, if the flame is too strong or flickering, the pressing force on the pressing component 2 can be appropriately reduced, thus decreasing the upward movement of the gas guide component 61 and narrowing the gap between the conical groove 62 and the conical block 63. This reduces the gas output and allows the gas to form a suitable mixing ratio with the rarefied air, preventing the flame from becoming too strong. If the flame is weak or goes out, the pressing force can be increased to push the gas guide component 61 further upward, widening the gap to increase the gas output and ensure stable combustion. In this way, the flame of the lighter can be adaptively adjusted according to specific usage conditions to meet the basic ignition needs in high-altitude areas.

[0051] Second Embodiment

[0052] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application, which provides a lighter with automatic flame adjustment for high-altitude areas, the second embodiment of this application proposes another type of lighter with automatic flame adjustment for high-altitude areas. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0053] Specifically, the second embodiment of this application provides a lighter with automatic flame adjustment for high-altitude areas, which differs in that the lighter with automatic flame adjustment for high-altitude areas also includes a shielding component 7, which is disposed on the outer side of the protective shell 3, and the protective shell 3 has a sliding groove 8 on its side.

[0054] The shielding assembly 7 includes a shielding frame 71, an anti-slip groove 72, and a slider 73. The shielding frame 71 is slidably connected to the outer side of the protective shell 3. The anti-slip groove 72 is formed on the side of the shielding frame 71. The slider 73 is fixedly installed on the inner side of the shielding frame 71 and is slidably connected to the inner side of the groove 8.

[0055] The working principle of the lighter with automatic flame adjustment for high-altitude areas provided by this utility model is as follows:

[0056] High-altitude areas are often accompanied by strong winds. When igniting, push the shielding frame 71 so that the slider 73 on its inner side slides upward along the groove 8 of the protective shell 3 until the shielding frame 71 covers the area around the through groove 31 at the top of the protective shell 3, forming a windproof barrier to reduce the interference of strong winds on the flame and prevent the flame from being blown out. The anti-slip groove 72 on the side of the shielding frame 71 increases the friction of the hand and makes it easier to push and operate.

[0057] When wind protection is not required, slide the shielding frame 71 downward to expose the through slot 31, which does not affect normal ignition and flame observation; the cooperation between the slider 73 and the slide groove 8 ensures that the shielding frame moves smoothly and avoids displacement or falling off.

[0058] Compared with related technologies, the lighter with automatic flame adjustment for high-altitude areas provided by this utility model has the following beneficial effects:

[0059] With the shielding component 7 in place, the shielding frame 71 can be slid up and down during use, taking into account both wind protection and normal use needs. The overall design enhances the practicality and reliability of the lighter in high-altitude environments.

[0060] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
