Heating cigarette

Abstract

A heating cigarette comprises a tobacco shred section, a hollow section and a filter tip section, and is characterized in that the hollow section is divided into two sections, namely a first hollow section and a second hollow section which are connected to the two ends of the tobacco shred section respectively, the other end of the second hollow section is connected with the filter tip section, and air holes are formed in the pipe wall of the second hollow section. Compared with the prior art, the cigarette has the advantages that the length of the second hollow section is shortened compared with that of hollow sections of most original cigarette structures, so that excessive key components cannot be intercepted in the first smoking stage, and nicotine, propylene glycol, glycerol and other components can be effectively released into smoke through the first mouth. Meanwhile, due to the existence of the first hollow section, part of water can be transferred to the first hollow section during smoking, so that the smoke temperature of the first two mouths can be effectively prevented from being too high, and the smoking experience of a user can be effectively improved on the whole.

Description

Technical Field

[0001] The utility model relates to a heated cigarette, which aims to solve the problem that the temperature of the first two puffs of conventional heated cigarettes is too high and the key components of the first puff cannot be fully released. The cigarette is designed with one end of the tobacco end connected to the hollow and the filter tip, and the other end connected to the hollow section. Through reasonable structural design and material selection, the tobacco temperature is effectively regulated, thereby improving the smoking experience and ensuring the release of key components. Background Art

[0002] According to existing research, it is found that key components of cigarettes such as nicotine, propylene glycol, and glycerol cannot be fully released during the first puff. One of the reasons is that the hollow segment has not reached a saturated state, which makes these components easily intercepted. Conventional heated cigarettes mostly have only one end of the tobacco segment directly connected to a longer hollow segment. However, during the first puff of the cigarette, the hollow segment may not have fully reached the saturation value, especially important components such as propylene glycol, glycerol, nicotine, and moisture. This phenomenon leads to a low content of these key components in the smoke during the first puff of the cigarette, affecting the smoking experience and the performance of the cigarette. At the same time, in conventional heated cigarettes, users often feel that the smoke is abnormally hot at the beginning of the puff, especially the first two puffs. This is mainly due to the fact that the moisture in the tobacco is heated to a higher temperature: the moisture in the tobacco will be quickly heated, converted into a vapor state, and mixed with the smoke, causing the temperature of the smoke to increase significantly. This situation is particularly obvious in the early stage of heating, because the moisture content in the tobacco is high at this time, resulting in a more prominent smoke temperature. Therefore, a new design is needed to solve the problem of key ingredients being easily trapped due to the unsaturated hollow section and the cigarette structure that controls the release of moisture in the tobacco and the heating process, so as to achieve a more effective release of these ingredients and improve the performance of the cigarette and the smoking experience. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a heated cigarette with hollow ends connected to both ends of the cigarette segment, which can effectively avoid the phenomenon of low release of key components in the first puff of smoke, and can also effectively prevent the smoke temperature from being too high during smoking.

[0004] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0005] A heated cigarette comprises a tobacco segment, a hollow segment and a filter segment, wherein the hollow segment is divided into two segments: a first hollow segment and a second hollow segment, which are respectively connected to the two ends of the tobacco segment, the other end of the second hollow segment is connected to the filter segment, and a ventilation hole is opened on the tube wall of the second hollow segment.

[0006] At least one row of air holes is provided on the tube wall of the second hollow section, and further, 2-4 rows of air holes may be provided.

[0007] The number of ventilation holes in each row is 4-15.

[0008] The diameter of the air holes does not exceed 1 mm.

[0009] The inner diameters of the second hollow sections may be the same or different, that is, there are multiple hollow sections with different inner diameters.

[0010] The second hollow section may have the same cross section or may be a plurality of hollow sections with different cross sections.

[0011] The length of the second hollow section is always greater than or equal to the length of the first hollow section.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The second hollow section is shorter than the hollow section of most cigarette structures, so it will not retain too many key components in the initial stage of smoking, so that nicotine, propylene glycol and glycerol and other components are effectively released into the smoke in the first puff. At the same time, part of the water will also be transferred to the first hollow section during smoking, which can effectively avoid the smoke temperature being too high in the first two puffs. Overall, it effectively improves the user's smoking experience. BRIEF DESCRIPTION OF THE DRAWINGS
