A small lighter actually uses an ignition device and a flammable gas or liquid to make a fire. There are many types of lighters available today, including disposable lighters, kerosene lighters, and arc lighters. But regardless of the type of lighter, the internal structure of these lighters is very simple. There is an ignition device, then it is associated with an oil cylinder or a cylinder for storing fuels.
The flammable gas used in lighters is usually butane or liquefied gas, which is then ignited by sparks generated by friction between flints. There is also a cotton wick on the lighter, which can prevent the lighter flame from going out until the lighter is extinguished and the air is cut off, the lighter flame will go out. the same every time.
Actually, at first, gasoline was used in lighters, but later, due to the forceyou smell of gasoline, it was rarely used. Today, cleaner liquefied gas is used instead. The liquefied gas will be precipitated into a sealed gas box via a pressurized device. This gas box is sealed when the liquefied gas is released and comes into contact with a spark, it expands quickly and ignites.
But liquefied gas is not very safe, so safer gases such as alkanes have been used. Although it is flammable, it does not react violently with metals, strong acids and oxygen. , so security will be better. After the combustion is completed, relatively clean and clean carbon dioxide and water can be formed, and it will not cause pollution to the environment.
But the ignition method has now been significantly improved. Early disposable lighters used an electric rod, which produced sparks when pressed. The lightersKerosene heaters primarily use the friction of flint to produce sparks. There is also an arc lighter that uses electrical energy to start a fire. Finally, there is also a type that uses magnetic induction to generate voltage to release sparks. Although the methods are different, they all produce sparks that ignite.
Is the igniter inside the lighter considered an ignition device?
There is a gas storage tank in the lighter , which stores a certain amount of gaseous fuel such as propane. This gas is slightly It can liquefy when under pressure, but vaporizes easily once the pressure is reduced. When the switch is pressed, the valve connected to the switch opens and the propane vaporizes and overflows. At the same time, the electronic lighter connected to the switch (the built-in piezoelectric ceramic cangenerate voltage with pressure) generates sparks due to high pressure. voltage, and the propane vapor encounters electrical sparks and thus ignites. The old flint lighter is the one with one wheel. When the wheel is turned, it rubs the flint installed under the wheel, causing sparks that ignite the propane vapor.
Forget it, the igniter inside the lighter is called piezoelectric ceramic. The principle of operation of a lighter is that after pressing the button with your hand, the pressure of your hand is converted into a pulse that acts on the piezoelectric ceramic by leverage, causing the generation of a high voltage by the piezoelectric ceramic and an arc discharge on the liquefied gas port which was opened at the same time.The piezoelectric igniter is a manual ignition device produced based on the piezoelectric effect and using the piezoelectric ceramic as ssupport.
