Description

Electric heating pipe with electronic cigarette suction function

technical field

The invention relates to the technical field of electric heating cigarettes, in particular to an electric heating pipe with the function of sucking electronic cigarettes.

Background technique

As the expansion and supplement of traditional cigarettes, the development of new tobacco products is inevitable, and related research work on electric heating cigarettes and electronic cigarettes has also begun. Electric heating cigarettes make tobacco products smoke by heating but not burning. Compared with traditional cigarettes, this technology can effectively reduce the harmful components of tobacco cracked in high temperature environment on the one hand, and reduce or even eliminate tobacco products on the other hand. Sidestream fumes during use. E-cigarettes generate smoke in the form of heated liquid e-liquid, which has the advantages of environmental protection and no second-hand smoke hazards.

The sensory comfort of cigarettes has a lot to do with the moisture content of the smoke. Studies have found that when the moisture content of the smoke is appropriate, the smoke is soft and delicate, with less irritation and better sensory comfort. When the moisture content of the smoke is low, the smoke will be dry and irritating. Increased sex, decreased sensory comfort. Nicotine in cigarette smoke includes two forms of bound nicotine and free nicotine. The irritation of smoke is mainly determined by the content of free nicotine. The relative content of the two forms of nicotine is related to the environment (such as humidity, pH) of the smoke. Free nicotine can combine with hydrogen ions in the smoke to form a salt (bound nicotine). When the moisture content (humidity) of the smoke is low, the concentration of hydrogen ions decreases, which will inhibit the formation of bound nicotine and also reduce the The water solubility of bound nicotine makes it easier to decompose to produce free nicotine, which increases the relative content of free nicotine and the corresponding increase in free nicotine/total nicotine, resulting in increased irritation and dryness. However, if the humidity of the smoke is too high, the content of free nicotine will be too low, and the physiological strength required by the smoker will not be reached. Therefore, changes in the moisture content (humidity) of smoke will significantly affect the morphological distribution of nicotine, resulting in significant changes in free nicotine and free nicotine/nicotine ratio. Under low humidity conditions, the content of free nicotine and the ratio of free nicotine to nicotine both increase, which makes cigarette products more likely to produce irritation when smoked in a dry environment than in a humid environment. In order to make the product have a higher ratio of free nicotine to nicotine, and ensure its stability in different humidity environments, so as to improve the problem of increased irritation of the product in a dry environment, glycerin can be added to shredded tobacco To increase the moisture content of cigarette smoke and improve the sensory comfort of cigarettes. However, studies have shown that humectants such as glycerin in shredded tobacco will undergo thermal cracking at low-temperature heating cigarette heating temperatures (above 400°C), generating harmful aldehydes (especially acrolein).

When smoking electric heating cigarettes, compared with traditional cigarette smoke, the harmful components cracked in high temperature environment are eliminated, and it has a certain characteristic tobacco flavor, but it also brings about a decrease in physiological satisfaction, a reduction in the amount of smoke, and comfort. problems such as poor degree. At present, flavoring is mainly used to make up for the problem of dilution and lightening of smoke due to the reduction of tar content, to improve the smoking taste of cigarettes, to enrich the aroma, and to maintain good sensory quality. The traditional supplementary method of flavoring and adding materials includes adding cotton thread soaked in liquid essence or adding microencapsulated flavor to the filter during the forming process of filter cellulose acetate, so that the flavor is released during smoking to improve the smoking taste of cigarettes. During the smoking process, with the continuous release of flavors and fragrances, the mixture of smoke and aroma components in each puff has inconsistency, which makes the taste of each cigarette have a large difference. In addition, the microcapsules containing spices need to be squeezed to release the aroma components, which brings inconvenience to suction.

The smoking principle of electronic cigarettes: the smoke oil is heated and vaporized into high-temperature steam on the electric heating element of the atomization system and sprayed out to the opening. Similar to the smoke of traditional cigarettes. Different from the smoke of traditional cigarettes, the aerosol particles of electronic cigarette smoke are tiny liquid droplets, and the particle diameter is smaller than that of aerosol particles in traditional cigarette smoke.

In terms of sensory quality, compared with traditional cigarettes, e-cigarettes generally have the disadvantage of insufficient fullness of the smoke in the mouth. The so-called fullness refers to the impact or presence of the smoke on the mouth felt by the smoker during the smoking process. A good fullness means that the obvious presence of smoke is felt during the inhalation process, and there is no empty feeling. In addition, according to the feedback of e-cigarette smokers, the existing e-cigarettes containing nicotine in the e-cigarette oil are more irritating to the smoker's throat and nasal cavity. , but its tobacco flavor is still not obvious enough.

The above reasons lead to the unsatisfactory sensory experience of consumers on electric heating cigarettes or electronic cigarettes, and the market acceptance of electric heating cigarettes or electronic cigarettes is not high.

In view of the above problems, the present invention provides an electric heating cigarette smoking device with electronic cigarette suction function, which can fully combine the advantages of electric heating cigarettes and electronic cigarettes, and provide better cigarette smoking sensory experience.

While free nicotine can satisfy the physiological feelings of smokers, it plays an important role in the improvement of sensory quality (especially comfort) .

Comparative experiment 2

Comparative Example 1: An electrically heated tobacco pipe with the function of sucking electronic cigarettes, the difference between it and the electrically heated pipe with the function of sucking electronic cigarettes in Example 1 is only that: the pipe in this comparative example does not It has a spiral airflow channel, and its airflow channels are all straight.

The same electrically heated cigarettes were smoked using the electrically heated pipes with electronic cigarette smoking function as described in Example 1 and Comparative Example 1 respectively, and the sensory quality evaluation was performed. The sensory quality evaluation results are shown in Table 6.

Sensory quality evaluation method:

Sensory quality evaluation items and scale setting: set 5 items, namely irritation, fullness, dryness, suction resistance, and smoke volume; the maximum scale of each item is 20, and each item is calculated as 1 point For each unit, see Table 5 for the meaning of each scale value corresponding to each evaluation item.
