Скачать или смотреть How Does A LIGHTER Work

A lighter typically works by using a flammable liquid fuel, such as butane, and a sparking mechanism to ignite the fuel and produce a flame. Here's how a typical disposable lighter works:

Fuel: Lighters contain a reservoir of flammable liquid fuel, usually butane, stored under pressure in a small chamber inside the lighter casing. Butane is commonly used because it is highly flammable, relatively inexpensive, and readily available.

Valve: The lighter has a valve mechanism that controls the release of the fuel from the reservoir. When you press down on the ignition button or lever of the lighter, it opens the valve, allowing a small amount of butane to escape from the reservoir.

Sparking Mechanism: Inside the lighter, there is a sparking mechanism, typically made of a metal wheel or bar, and a flint. When you flick the wheel or bar, it rubs against the flint, generating sparks due to friction. This sparking mechanism is what ignites the flammable gas.

Ignition: As the butane gas is released from the reservoir, it mixes with oxygen in the surrounding air. When a spark is generated by the sparking mechanism, it ignites the mixture of butane and oxygen, creating a small flame at the tip of the lighter.

Flame: The flame produced by the ignition of the butane gas provides a source of heat and light. It can be used to light cigarettes, candles, campfires, or any other item that requires ignition.

Safety Features: Many lighters are equipped with safety features to prevent accidental ignition, such as child-resistant mechanisms or a lock switch that prevents the ignition button from being depressed when not in use.

Disposable lighters are convenient and widely used for various purposes, but it's important to handle them with care and follow safety precautions to avoid accidents or injuries.
