Description

Technical Field

[0001] The present disclosure relates to the technical field of tobacco products, and in particular to a low-adsorption mouthpiece and a heated cigarette. Background Art

[0002] Heat-not-burn tobacco products mainly heat tobacco flakes or shredded tobacco through a heating source. The heating temperature is just enough to make the tobacco leaves emit a smoky aroma, but the tobacco leaves will not be ignited. The aroma components and nicotine are only volatilized to meet the needs of smokers. Since the tobacco flakes or shredded tobacco are not burned but only heated, the harmful components produced by high-temperature combustion and cracking of tobacco are avoided, reducing the health risks of consumers. Compared with other new tobacco products, heat-not-burn tobacco products have attracted much attention because they are closest to traditional cigarettes in terms of sensory quality and smoking method.

[0003] In the related technology, most heated cigarettes adopt a three-stage type, namely, the smoking section, the cooling section (support section), and the filtering section. When the cigarette reaches the atomization temperature under the heating conditions of 250-350°C, the atomizer and flavor substances in the smoking section material vaporize and condense to form an aerosol. Since the smoking medium of heated cigarettes is less than that of traditional cigarettes, and only low-temperature heating without high-temperature combustion, the amount of smoke of heated cigarettes is greatly reduced compared to traditional cigarettes, and the smoking satisfaction and experience are poor.

[0034] Acetate fiber is used in traditional cigarette filters due to its good adsorption and formability. In related technologies, the filter segment of heated cigarettes uses traditional acetate fiber. However, due to the good adsorption of acetate fiber, the filter segment adsorbs more smoke and flue gas, which to a certain extent reduces the satisfaction and experience of consumers when smoking heated cigarettes.

[0035] The inventors of the present disclosure have discovered that the filter segment can be improved to reduce its adsorption of smoke and smoke, thereby enhancing consumers' satisfaction and experience when smoking heated cigarettes.

[0036] In view of this, the present disclosure provides a low-adsorption mouthpiece for heating cigarettes to reduce the adsorption of smoke and smoke. Through the design of low-adsorption materials, smoke can flow out of the low-adsorption mouthpiece quickly and smoothly, with sufficient smoke volume, thereby improving the satisfaction of smoke inhalation.

[0037] Figure 1 A cross-sectional schematic diagram of a low-adsorption mouthpiece for heating cigarettes according to an embodiment of the present disclosure is shown.

[0039] According to the embodiments of the present disclosure, the film-forming property and hydrophobicity of the silicone oil reagent are utilized to form a low-adsorption film in situ on the surface of the paper base, and the low-adsorption paper base 11 including the low-adsorption film forms a low-adsorption section 1, which can reduce the adsorption of smoke and smoke by the mouthpiece, so that the smoke and smoke can flow out of the low-adsorption section 1 quickly and smoothly, and the amount of smoke is sufficient, thereby improving the satisfaction and experience of smoking heated cigarettes. In addition, the low-adsorption film polymerized by amino silicone oil and / or vinyl silicone oil has good temperature resistance, which improves the temperature resistance of the low-adsorption section 1.

[0040] In addition, by using in-situ polymerization, the silicone oil reagent can enter the pores of the paper base, which can improve the bonding strength between the paper base and the low-adsorption membrane and reduce the amount of the low-adsorption membrane used.

After the pre-folded low-adsorption paper base 11 exits the double pressure rollers, the belt is driven by a motor-driven pulley to pull the folded low-adsorption paper base 11 to reduce slippage. At the same time, the pulley squeezes and fixes the folded low-adsorption paper base 11 to a certain extent, thereby improving the pore uniformity and roundness to a certain extent, and finally wrapped by the molding paper 12.

[0092] Example 10

[0093] This embodiment provides a heating cigarette including a low-adsorption mouthpiece and a preparation method thereof, with reference to Example 1, which is different from Example 1 in that: in this embodiment, the surface of the paper base has no embossing.

[0094] Comparative Example 1

[0095] This comparative example provides a heated cigarette and a preparation method thereof, with reference to Example 1, which is different from Example 1 in that: in this comparative example, the adsorption section is formed by ordinary acetate fiber.

[0096] Comparative Example 2

[0097] This comparative example provides a heated cigarette and a preparation method thereof, referring to Example 1, which is different from Example 1 in that: in this comparative example, the mouthpiece used includes a paper base segment, the paper base segment includes a shaping paper, and a paper base wrapped in the shaping paper, and the paper base does not include a low-adsorption film.

[0098] The heated cigarettes provided in the above embodiments and comparative examples were subjected to a smoking experiment in an existing commercially available central heating device, and smoke from four heated cigarettes was collected on each filter disc. The smoking conditions were: preheating the device for 18 seconds, taking a puff for 2 seconds, an interval of 28 seconds, and a puff volume of 55 ml per puff. The smoke atomizer, nicotine, and moisture content in the smoke were analyzed, and the average values ​​were calculated, as shown in Table 1.

[0099] Table 1

[0100]

[0101] It can be seen from the analysis of Table 1 that, compared with the comparative example, the heated cigarette including the low-adsorption mouthpiece provided by the embodiment of the present disclosure has a low interception amount of smoke and fog, and the smoke and fog flow out of the low-adsorption section quickly and smoothly, with sufficient smoke volume, thereby improving the satisfaction and experience of smoking.

[0102] Further, according to Table 1, from the analysis of Example 1 and Example 5, Example 2 and Example 6, it can be seen that as the amount of silicone oil reagent coated on the paper base decreases, the adsorption effect of the paper base on smoke increases, and the release of the atomizer (propylene glycol) and water in the smoke gradually decreases, which is reflected in the reduction of the amount of smoke during inhalation and the weakening of the sense of satisfaction.

[0103] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present disclosure. It should be understood that the above description is only a specific embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the protection scope of the present disclosure.
