Description
Technical Field
[0001] The invention belongs to the technical field of lighters, and in particular relates to an automatic flame height regulating device for lighters in a high-altitude environment. Background Art
[0002] With the rapid development of science and technology, there are more and more types of lighters, but the most commonly used ones are still those mainly composed of an ignition mechanism and a gas storage box. The ignition mechanism is generally pneumatically activated by pressing the ignition button on the lighter. When the ignition mechanism is activated, sparks burst out and shoot towards the gas area, igniting the gas, thereby achieving the purpose of ignition. This lighter has a simple structure and is easy to operate.
[0003] However, common lighters cannot be used normally in high-altitude areas, cannot adjust the flame size according to the external environment, and lack a certain degree of adaptability to the external environment. Summary of the invention
[0004] The purpose of the present invention is to provide a lighter flame height automatic adjustment device in a high altitude environment in order to solve the above-mentioned problem.
[0005] The technical solution adopted by the present invention is as follows: an automatic adjustment device for the flame height of a lighter in a high-altitude environment, comprising a lighter housing, a pressure plate being arranged on the upper surface of the lighter housing near the front end edge, a connecting rod being welded to the center position of the rear surface of the pressure plate, a protruding rod being fixedly connected to the rear surface of the connecting rod, an oil pipeline being installed through the end of the protruding rod, a fixed block being connected to the end of the protruding rod located inside the oil pipeline, a fixed ring being installed outside the fixed block, a stopper being welded to the rear surface of the fixed block located at the upper end of the fixed ring, a micro valve being rotatably installed inside the fixed ring, a valve shaft being rotatably arranged between the side circumferential surface of the micro valve and the inner surface of the fixed ring.
[0006] By adopting the above technical solutions, the micro manual adjustment valve of this lighter solves the problem of unstable flame through intuitive mechanical design in high-altitude areas. Users can directly press the pressure plate to quickly respond to low-pressure environments. The structure can control the gas flow and change the flame height. The unique design inside the valve can isolate the external strong wind interference and prevent flameout. At the same time, the flexible shell has a built-in spring limiter, which can rebound when pressed to the maximum opening to prevent excessive gas leakage. The purely mechanical structure does not require electricity. Just press the plate lightly to accurately control the fire under extreme conditions such as wind, snow, and plateaus. It takes into account both convenient operation and safety and reliability. It is especially suitable for outdoor adventures and emergency rescue scenarios.
[0007] In a preferred embodiment, a flame outlet is provided on the upper surface of the lighter housing near the rear end edge, and a conductive block is provided on the upper edge of the inner circumferential surface of the flame outlet.
[0008] By adopting the above technical solution, the conductive block design in the flame regulation system of the device brings great advantages, avoiding rust in the humid environment of the plateau and ensuring the long-term stability of the circuit. The purely physical structure does not require batteries, and with the self-powered system, the device can operate reliably in an environment of -30℃ to 50℃, extending the battery life.
[0009] In a preferred embodiment, a sparking wheel is rotatably mounted on the upper surface of the lighter housing, located on the upper side of the pressure plate, a rotating shaft is welded at the center of the side surface of the sparking wheel, and a rotating shaft fixing block is provided between the upper surface of the lighter housing and the outer circumferential surface of the rotating shaft.
[0010] By adopting the above technical solution, in this device, the spark wheel is locked on the upper surface of the lighter through the shaft fixing block, which significantly improves the ignition reliability in plateau environments. The shaft adopts a low-temperature lubricating coating, which can still rotate smoothly at -30℃ to avoid ice jam; the fixing block and the shell are integrally formed to eliminate the risk of loose parts caused by frequent friction; the spark wheel is equipped with anti-slip patterns on the surface, so sparks can be stably produced even when wearing gloves. The closed structure isolates dust and moisture, and with the high-hardness ceramic spark wheel, the service life is extended to more than the traditional design, adapting to harsh conditions such as strong winds and low temperatures on the plateau.
[0011] In a preferred embodiment, a polygonal groove is provided at the front end of the lower surface of the lighter housing, and an oil delivery port is provided at the rear end of the lower surface of the lighter housing.
[0012] By adopting the above technical solution, in this device, the polygonal groove is used for the installation and removal of the fire stick, and the oil delivery port is equipped with a conical spring pressure piece, which automatically shrinks the aperture when the altitude rises, accurately controls the oil output, and prevents excessive flames or smoke. The silicone sealing ring on the edge of the groove and the self-locking thread design of the oil delivery port ensure that it is still leak-proof at a low temperature of -30℃.
[0013] In a preferred embodiment, a flame outlet chamber is installed on the inner wall of the flame outlet, a central flame outlet is opened through the center of the upper surface of the flame outlet chamber, and an annular flame outlet is opened through the upper surface of the flame outlet chamber at the periphery of the central flame outlet.
[0014] By adopting the above technical solutions, the ring and center dual-channel structure in the flame outlet design of the device significantly improves the adaptability to plateaus: the ring-shaped flame outlet introduces external air through the side wall guide holes to enhance gas premixing and ensure full combustion under low pressure; the center flame outlet maintains the stability of the main flame and forms a double-layer thermal barrier with the ring flame to enhance wind resistance. The dual channels are integrally formed with nickel-based alloy, which does not shrink or crack at a low temperature of -30°C, and carbon deposits can be deposited in the ring gap to avoid the risk of blockage of a single outlet and extend the service life.
[0015] In a preferred embodiment, an annular outer shell is fixedly connected to the lower surface of the flame outlet bin.
[0016] By adopting the above technical solution, an annular shell is installed at the lower end of the flame outlet chamber, the purpose of which is to protect the internal pipeline connecting the internal oil pipeline and the annular flame outlet and the central flame outlet, thereby protecting the use effect of the lighter.
[0017] In a preferred embodiment, the upper end of the oil pipeline is located inside the annular housing and is fixedly connected to an oil pipeline fixing block, and a main oil pipeline is penetrated through the center of the surface of the oil pipeline fixing block.
[0018] By adopting the above technical solution, in the device, the auxiliary pipe replenishes atomized fuel through the annular port to ensure complete combustion when oxygen is thin and improve wind resistance. Even if the main oil circuit is slightly blocked, the auxiliary pipe can still ensure the ignition success rate and adapt to the changing environment of the plateau.
[0019] In a preferred embodiment, a secondary oil pipeline is opened through the center of the surface ring of the oil pipeline fixing block.
[0020] By adopting the above technical solution, in this device, the design of the center flame outlet directly connected to the main oil pipeline is targeted to optimize the stability of plateau flames. First, it can accurately supply oil to ensure that the center flame continues to be strong; second, it can be wind-resistant, and the center flame outlet adopts a tapered design to accelerate the gas injection to form a high-density flame column, which is combined with the high-temperature resistant ceramic inner wall to resist the impact of strong winds; third, it can achieve a long-life structure, and the one-piece stainless steel pipeline is seamlessly connected to the flame outlet to eliminate the risk of oil leakage and ensure the reliability of ignition in extreme plateau environments.
[0021] In a preferred embodiment, a pressing block is installed on the upper surface of the pressing plate near the front end edge.
[0022] By adopting the above technical solution, a pressing block is installed at the front edge of the upper surface of the pressing plate, the purpose of which is to increase the friction force of the operator's fingertips pressing the pressing plate, prevent it from falling off, and improve the effect of equipment use.
[0023] In a preferred embodiment, a flexible shell is connected to the rear end edge of the lower surface of the pressing plate, and a spring is installed between the upper and lower surfaces inside the flexible shell.
[0024] By adopting the above technical solution, a flexible shell is connected to the lower end of the pressure plate, and a spring is arranged inside the flexible shell, the purpose of which is to achieve the pressing effect of the pressure plate. The operator controls the size of the flame by pressing the pressure plate, reducing the difficulty of operation.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0026] In the present invention, in high-altitude areas, the micro manual adjustment valve of this lighter solves the problem of unstable flame through intuitive mechanical design. Users can directly press the pressure plate to quickly respond to low-pressure environments. The structure can control the gas flow and change the flame height. The unique design inside the valve can isolate external strong wind interference and prevent flameout. At the same time, the flexible shell has a built-in spring limiter, which can rebound when pressed to the maximum opening to prevent excessive gas leakage. The purely mechanical structure does not require electricity, and lightly pressing the plate can accurately control the fire under extreme conditions such as wind, snow, and plateaus. It takes into account both convenient operation and safety and reliability, and is particularly suitable for outdoor adventures and emergency rescue scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
