As an aid to smokers in their daily use, the operating principle of the mouthpiece filter involves knowledge from many fields such as physics, chemistry and materials science.
It does not exist to make smoking harmless, but to minimize the harm to smokers and the surrounding environment caused by harmful substances produced during smoking.
Let's first take a look at the basic structure of the mouthpiece filter.
Generally speaking, a mouthpiece filter consists of three parts: the shell, the filter material, and the nozzle.
The shell is usually made of metal or plastic, which has good high temperature resistance and corrosion resistance; The filter material is the core part of the mouthpiece filter, and its performance is directly related to the quality of the filtration effect; The nozzle is the part that the smoker directly touches and needs to be comfortable and non-slip.
1. Physical filtering mechanism
Physical filtration is one of the most basic working principles of a mouthpiece filter.
When a smoker inhales tobacco smoke through a mouthpiece, the first thing they encounter is the physical filter. This layer is usually made up of fibrous materials, such as special mouthpiece cotton or fiberglass.
These fibrous materials have a fine pore structure that is able to intercept larger particulate matter in smoke, such as tar, soot, etc. Due to their large physical size, these particulate matter cannot pass through the pores of the fibrous material and are effectively trapped inside the filter.
In addition to interception, the physical filtration mechanism also includes adsorption.
The inside of the cigarette nozzle filter often contains adsorption materials such as activated carbon.
Activated carbon has a huge surface area and rich pore structure, which can adsorb tiny particles and harmful substances in smoke, such as heavy metal ions, benzopyrene and other carcinogens. These harmful substances are adsorbed on the surface of the activated carbon or inside the pores as they pass through the activated carbon layer, thereby reducing the amount of harmful substances in the smoke.
2. Chemical filtration mechanism
In addition to physical filtration, some mouthpiece filters also use a chemical filtration mechanism to further purify the smoke, which mainly includes catalytic reactions and chemical reactions.
Catalytic reaction refers to the transformation of harmful chemicals in smoke through the action of catalysts to produce safer substances. For example, some advanced mouthpiece filters incorporate *** catalysts, such as platinum or palladium, that accelerate the oxidation of carbon monoxide and harmful aldehydes in smoke, thereby reducing their content.
A chemical reaction is when certain chemicals in the filter react directly with the harmful substances in the smoke to reduce or eliminate the content of these substances. For example, a chemical substance, such as an oxidizing or reducing agent, can be added to the mouthpiece filter that reacts chemically with harmful substances in the smoke. These chemicals are capable of redox reactions with harmful substances in the smoke, thus converting them into harmless or low-toxic substances.
3. Material and technological progress
The performance of the mouthpiece filter is closely related to the materials and technologies used.
Modern mouthpiece filters use a variety of high-performance materials, such as mouthpiece cotton, fiber factor, activated carbon, etc., used in some models of joyo mouthpieces, which can improve filtration efficiency and purification effect. At the same time, with the continuous development of nanotechnology and other advanced technologies, the design and performance of mouthpiece filters are also improving.
For example, nanomaterials are widely used in the manufacture of cigarette mouth filters due to their unique physical and chemical properties.
Nanofibers have a higher specific surface area and better adsorption performance, which can more effectively intercept and adsorb harmful substances in smoke. In addition, nanocatalysts can also promote the occurrence of catalytic reactions at lower temperatures, thereby improving the catalytic efficiency of filters.
Although mouthpiece filters are able to reduce the harmful substances in tobacco smoke to a certain extent, we must recognize that mouthpiece filters cannot completely eliminate all harmful substances in smoke, especially addictive substances such as nicotine.
For smokers, the best option is still to quit or reduce the amount of cigarettes smoked to maintain their own health and the health of others.
