Description

Smoking system and smoking device thereof

Technical Field

The invention relates to the technical field of smoking sets, in particular to a smoking system and a smoking device thereof.

Background

Traditional cigarettes have been used for over 100 years as the mainstream product for tobacco consumption. With the change of life style and consumption concept of people, the rapid progress of scientific technology and the continuous acceleration of the upgrading and updating speed of commodities, the demand and the focus of tobacco consumers are continuously changed and are influenced by factors such as tobacco control, social public opinion and the like, the development of the traditional cigarette is restricted, and the appearance of a novel cigarette becomes inevitable.

Research shows that cigarette smoke generated by cigarette combustion has great harm to non-smoking people, and fire caused by smoking is difficult to stop. The nicotine and most of tobacco aroma components can be transferred into the smoke at 200-500 ℃, the burning temperature of the conventional cigarette is above 800 ℃, if the heated temperature of the cigarette is reduced to below 500 ℃, various harmful components in the smoke can be greatly reduced, and meanwhile, the influence on the aroma components is relatively small. Therefore, the research on the heating non-combustion cigarette smoking device which avoids the combustion of the tobacco shreds and meets the requirements of consumers is very significant.

Traditional low temperature cigarettes deliver nicotine and flavor to the body by heating the non-burning tobacco, which is filled with tobacco material. The low-temperature cigarette product changes the traditional mode that visible smoke is adopted in cigarette burning and the mode of heating without burning is adopted. Related studies have shown that at lower temperatures below 500 ℃, tobacco, nicotine and some of the tobacco flavor components can be transferred to the smoke by heating but not burning the tobacco. Compared with the traditional cigarette, the low-temperature cigarette can greatly reduce the release amount of tar and harmful ingredients integrally. Meanwhile, the smoke of the side stream is basically avoided, and the harm to other people and the environment is small.

The electrically heated low temperature cigarette is one kind of low temperature cigarette with electric power as heat source to heat tobacco matter and produce nicotine smoke. Conventional electrically heated, low temperature cigarettes are smoked with a lower total particulate matter during the initial puff but tend to increase progressively until finally giving the consumer the sensation of a progressively increasing smoke intensity. When the heating chamber adopts the conventional cigarette of integral type heating mode suction, the flue gas is initial very weak, then rises rapidly, then along with the increase of suction mouth number, and the flue gas volume is showing and is reducing. This is mainly because it takes the first few puffs to reach an optimal temperature, causing the tobacco product to produce a high concentration of aerosol, which however is depleted as the puff progresses. Compared with the conventional cigarette, the cigarette has uncontrollable smoke release amount, larger sensory difference among different suction openings, and weakened sensory characteristics in the later period of smoking.

Each heating element 142 defines a heating cavity 142a, and the heating cavities 142a of the plurality of heating elements 142 form an accommodating cavity 144 for accommodating the smoking article 200. The receiving chamber 144 has an insertion opening 146 for inserting the smoking article 200 and an air inlet hole 148 communicating with the air inlet 122 at both ends thereof. The plurality of heating elements 142 independently control the temperature and sequentially heat the smoking article 200 from the insertion opening 146 in a direction toward the air intake apertures 148.

Since the plurality of heating elements 142 of the heating pan 140 are independently temperature controlled and heat sequentially from the insertion opening 146 to the air inlet 148, the smoking article 200 can be sequentially heated from the end of the mouthpiece 240 in a direction away from the mouthpiece 240. High-concentration aerosol generated during integral heating is avoided, and the smoke release amount in the suction process is consistent, so that the sensory difference among different suction openings is balanced, and the consistency of the smoke taste is improved.

In addition, if the heating pan 140 heats the smoking article 200 in the opposite sequence from the one end of the smoking article 200 to the mouthpiece 240, the airflow passing through the heated tobacco segment 242 has a higher temperature, which heats the tobacco segment 242 passing behind, so that a part of the smoke components in the tobacco segment 242 which is not heated sublimates or the smoke components with lower decomposition temperature are released, and the smoke components in the post-heated tobacco segment 242 are carried away in advance, resulting in inconsistent smoke taste when the different tobacco segments 242 are heated. Meanwhile, the cigarette is heated prematurely, so that partial smoke is generated or the cigarette is thermally degraded due to heating, and the quality of the cigarette is changed. Reheating previously heated parts can result in the production of unpleasant odors or harmful components. In the present embodiment, the heated airflow does not flow through the tobacco segment 242 that is not heated by the sequential manner from the end of the cigarette holder 240 to the direction away from the cigarette holder 240, so as to avoid the above-mentioned problems of inconsistent taste and unpleasant odor or harmful components.

In one embodiment, the smoking device 100 also generally includes a power module 160 for powering the heating pan 140, the power module 160 being connectable to the housing 120 outside of the housing 120, and in other embodiments, the power module 160 may be located inside of the housing 120. Alternatively, the smoking device 100 itself does not include the power supply assembly 160, and the smoking device 100 is removably connected to the external power supply assembly 160 to provide power to the heating pan 140.

For more precise control and monitoring of the temperature of the heating pan 140, in one embodiment, the heating pan 140 further comprises a plurality of temperature sensors 152, and at least one temperature sensor 152 is disposed on each heating element 142. In one embodiment, the heating pan 140 further comprises an insulating gasket 154, wherein the insulating gasket 154 is positioned between adjacent heating elements 142 to prevent heat conduction between the heating elements 142 from affecting each other.

In an embodiment, the smoking device 100 can further include a controller disposed within the receiving cavity for controlling independent power to the plurality of heating elements 142. The temperature sensor 152 may be in communication with a controller, which may control the power supplied to the heating element 142 according to the temperature detected by the temperature sensor 152, so as to adjust the temperature of the heating element 142 more accurately.

The heating temperature of the heating element 142 is generally 200 ℃ to 500 ℃, nicotine and most of tobacco aroma components can be transferred into smoke at 200 ℃ and 500 ℃, and harmful gases or ignition of the smoking article 200 are easy to generate due to overhigh temperature. Further, in one embodiment, the heating temperature of the heating element 142 is 200 ℃ to 350 ℃. The temperature is controlled to be lower, on one hand, the safety control is facilitated, the scald is avoided, on the other hand, nicotine and tobacco aroma components can be released at a stable speed, and the taste of the cigarette is better.

In one embodiment, a preheating channel 156 is formed between the inner wall of the housing 120 and the outer wall of the heating pan 140, and one end of the preheating channel 156 is communicated with the air inlet 122, and the other end is communicated with the air inlet 148. Referring to the arrows in fig. 1, when smoking the smoking article 200, the external air enters the preheating channel 156 through the air inlet 122, is preheated by the outer wall of the heating pan 140, enters the accommodating cavity 144 through the air inlet 148, and enters the smoking article 200. The design preheats passageway 156, can reduce the temperature of the outer wall of heating pot 140 on the one hand, and then reduces the temperature of casing 120, prevents to scald one's hand, and on the other hand can high-efficiently utilize the heat of heating pot 140, avoids the energy waste.

In one embodiment, the housing 120 is tubular, the heating element 142 can be tubular, and the smoking article 200 can be heated more uniformly, with the air inlet 122 and the insertion opening 146 both located at an end opening of the housing 120. Further, in the embodiment where the smoking device 100 includes the power module 160, the power module 160 may be located at the other end of the housing 120, so that the overall structure is more reasonable and the device is convenient to hold and use.

In the embodiment shown in figure 1, the smoking article 200 may be a conventional commercially available cigarette, while referring to figures 3 and 4, in another embodiment, the smoking article 200 comprises a tobacco rod 220 and a mouthpiece 240, the tobacco rod 220 being connected at one end to the mouthpiece 240. The tobacco rod 220 is inserted into the accommodating cavity 144, and the tobacco rod 220 comprises a plurality of tobacco segments 242 which are connected in sequence, and the plurality of tobacco segments 242 correspond to the plurality of heating elements 142 one by one. The tobacco segments 242 correspond to the heating elements 142, and the plurality of tobacco segments 242 are matched with the plurality of independently controlled temperature heating elements 142, so that the temperature of different tobacco segments 242 can be controlled conveniently, and the components of the tobacco segments 242 can be adjusted as required, so that the mouthfeel is better.

In one embodiment, the tobacco segment 242 includes tobacco material 244 and phase change material 246, the phase change material 246 being disposed within the tobacco material 244. Because the phase change material 246 absorbs a large amount of heat or emits a large amount of heat during the phase change process, the temperature rise and the temperature drop can be delayed, and the temperature rise or the temperature drop can be prevented from being too fast, so that the temperature of the smoking article 200 can be better controlled.

In one embodiment, the smoking article 200 further comprises an insulation layer 260, the insulation layer 260 being located between two adjacent tobacco segments 242, and one insulation layer 260 may be disposed between each two adjacent tobacco segments 242 to prevent heat conduction between the tobacco segments 242 from affecting each other. Further, in one embodiment, the insulation layer 260 may also be located between the mouthpiece 240 and the tobacco segment 242 connected to the mouthpiece 240 to prevent heat from being conducted to the mouthpiece 240. Referring also to fig. 4, in another embodiment, the adjacent tobacco segments 242 may be directly connected without the heat insulating layer 260, so as to improve the consistency of the taste of the smoke and avoid the temperature from increasing or decreasing too fast.

To avoid melting of the phase change material 246 prior to being drawn into the mouth cavity, and referring also to fig. 5, in one embodiment, the smoking article 200 can further include a receptacle 280 for receiving the phase change material 246, the phase change material 246 being located within the receptacle 280, and further, the receptacle 280 being a thermally conductive material having a melting point generally greater than or equal to 500 ℃. The melting point of the container 280 needs to be higher than the heating temperature of the heating element 142. In one embodiment, the material of the container 280 is aluminum foil. The receiver 280 is thermally conductive to facilitate heat equalization within the tobacco segment 242. The receptacle 280 may be shaped like a capsule with the phase change material 246 encased within the receptacle 280. In one embodiment, the plurality of receptacles 280 is provided, and the plurality of receptacles 280 are evenly distributed in the tobacco material 244 of each tobacco segment 242, which further facilitates heat equalization within the tobacco segment 242.

Phase change material 246 may be granular, filamentous, or the like. In one embodiment, the phase change material 246 has a solid-to-liquid phase change temperature of 200 ℃ to 500 ℃, and when the heating element 142 heats the phase change material 246 to the solid-to-liquid phase change temperature, the phase change material 246 melts, and the phase change material 246 is undergoingA large amount of heat is absorbed during the phase change process, thereby avoiding a too fast temperature rise. When the temperature of the phase change material 246 is lower than the solid-liquid phase change temperature, the phase change material 246 solidifies and the phase change material 246 emits a large amount of heat during the phase change process, thereby preventing the temperature from dropping too fast. In one embodiment, the phase change temperature of the phase change material 246 may also be selected to be between 240 ℃ and 350 ℃. For example, phase change material 246 may be, for example, sodium nitrate NaNO₃。

In one embodiment, the composition of the tobacco material 244 in the plurality of tobacco segments 242 is different. The ingredients of each tobacco segment 242 can be adjusted as desired to provide a better mouth feel. For example, different tobacco sections 242 use different types of tobacco 244, so that taste and flavor are changed during smoking, and smoking experience is enriched. In one embodiment, the tobacco material 244 of the plurality of tobacco segments 242 includes a tobacco component that produces a lower decomposition temperature tobacco component in a decreasing proportion from the end proximate the mouthpiece 240 to the end distal the mouthpiece 240. Because the smoke generated by the tobacco segment 242 far away from the mouthpiece 240 flows through the tobacco segment 242 near the mouthpiece 240, although the smoke is already released by the tobacco segment 242 near the mouthpiece 240, a small amount of low-temperature decomposed smoke is still released when the smoke with certain heat enters subsequently, and therefore, the proportion of the components of the smoke is gradually reduced from the end near the mouthpiece 240 to the direction far away from the mouthpiece 240, which is more beneficial to improving the consistency of the smoke taste.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
