Description

A mouthpiece capable of adjusting cigarette smoke concentration and cigarette containing the same

technical field

The invention belongs to the technical field of cigarettes, and in particular relates to a mouthpiece capable of adjusting the concentration of cigarette smoke and a cigarette containing the same.

Background technique

Since smoking and health have become the focus of attention, the tobacco industry has worked hard to reduce the amount of tar in the smoke. Low-tar cigarette products have been gradually developed to meet the needs of different consumers. Many components in mainstream cigarette smoke have different effects on human health.

Most of the existing coke reduction technologies reduce the content of tar and nicotine in tobacco leaves through various processing methods. This method is not only costly, but also pollutes the environment. At present, there are two main ways to calculate the content of tar and nicotine in a cigarette, one is to detect the actual content of cigarette and nicotine in a cigarette; the other is to calculate the content of tar and nicotine in a cigarette smoke . Therefore, the concentration of smoke can be reduced by physical methods, that is, the content of tar and nicotine in the smoke can be reduced.

At present, the cigarettes on the market are finalized at the factory, and products that allow consumers to choose their own smoke concentration are relatively rare.

In order to meet the increasing demands of consumers and solve the above problems, the present invention is proposed.
