Description
Translated fromChinese技术领域technical field
本发明涉及卷烟滤嘴设计加工领域，更具体地，涉及一种可变通风量的滤嘴及卷烟。The invention relates to the field of design and processing of cigarette filter tips, and more particularly, to a filter tip with a variable ventilation volume and a cigarette.
背景技术Background technique
卷烟的抽吸方式既可以采用明火点燃的方式燃烧烟丝，也可以通过不燃烧的方式烘烤烟丝释放烟气。无论采用哪种方式释放烟气，都需要通过滤嘴进行过滤烟气后进入人体。The smoking method of cigarettes can either burn the shredded tobacco by igniting an open flame, or release the smoke by baking the shredded tobacco in a non-burning way. No matter which way the smoke is released, it needs to be filtered through the filter before entering the human body.
目前的滤嘴设计往往只是单独考虑满足单一的情况，例如仅满足点燃抽吸的情况或者仅满足不燃烧抽吸的情况。而使用者存在既需要点燃抽吸烟气，也需要不燃烧抽吸烟气的需求，在这种情况下，传统的滤嘴设计就不能满足使用者的需求，给使用者带来不便。The current filter design is often only considered to satisfy a single condition, such as only satisfying the condition of ignited suction or only meeting the condition of non-combustion suction. However, the user needs to ignite the smoking gas and not burn the smoking gas. In this case, the traditional filter tip design cannot meet the user's needs, which brings inconvenience to the user.
现有技术对于滤嘴的改进仍局限于单一的抽吸方式，例如，申请号为201721766369.9的中国专利，该篇专利文献通过在滤棒和水松纸之间设置高透纸并在高透纸上涂覆相变材料，以自动改变通风量。而这样的结构设计也仅仅只能满足点燃烟抽吸烟气的自动调节。对于消费者日益增长的使用需求，现在仍缺少一种能够既能满足点燃抽吸方式，也能满足不燃烧加热抽吸方式的滤嘴。The improvement of the filter tip in the prior art is still limited to a single suction method. For example, the Chinese patent with the application number of 201721766369.9, this patent document is arranged between the filter rod and the tipping paper. Coated with phase change material to automatically change ventilation. And such a structural design can only satisfy the automatic adjustment of lit cigarettes and smoked cigarettes. For the increasing use demands of consumers, there is still a lack of a filter that can satisfy both the ignition suction method and the non-combustion heating suction method.
发明内容SUMMARY OF THE INVENTION
本发明主要解决的技术问题是针对现有技术中缺少一种既适用于点燃抽吸方式同时也适用于不点燃加热抽吸方式的卷烟，提供一种可变通风量的滤嘴。The main technical problem to be solved by the present invention is to provide a filter tip with a variable ventilation volume in view of the lack of a cigarette suitable for both lit smoking mode and non-lit heating smoking mode in the prior art.
本发明所要解决的另一个技术问题为，提供采用一种所述可变通风量滤嘴的卷烟。Another technical problem to be solved by the present invention is to provide a cigarette using the variable ventilation filter tip.
为了解决上述技术问题，本发明采用的具体技术方案为：In order to solve the above-mentioned technical problems, the concrete technical scheme adopted in the present invention is:
一种可变通风量的滤嘴，包括滤芯和包覆层，所述包覆层包裹住所述滤芯；所述滤芯包括烟气进入端和烟气释放端；所述包覆层上设有相变通风区和非相变通风区，所述相变通风区上设有多个第一通风孔，所述非相变通风区上设有多个第二通风孔；外界空气通过所述第一通风孔和所述第二通风孔分别穿过所述包覆层深入至部分所述滤芯；所述第一通风孔内填充有相变材料；所述滤芯内靠近所述烟气进入端的部分设有淀粉管；所述相变材料的相变温度范围为45～60℃。A variable ventilation filter tip, comprising a filter element and a coating layer, the coating layer wraps the filter element; the filter element includes a smoke inlet end and a smoke release end; the coating layer is provided with a phase change A ventilation area and a non-phase-change ventilation area, the phase-change ventilation area is provided with a plurality of first ventilation holes, and the non-phase-change ventilation area is provided with a plurality of second ventilation holes; the outside air passes through the first ventilation The hole and the second ventilation hole penetrate through the coating layer and penetrate into part of the filter element respectively; the first ventilation hole is filled with phase change material; the part of the filter element close to the inlet end of the smoke is provided with Starch tube; the phase change temperature of the phase change material ranges from 45 to 60°C.
本发明在包覆层设置相变通风区和非相变通风区，在相变通风区和非相变通风区上分别设有第一通风孔和第二通风孔，第一通风孔内填充有相变材料，可随温度变化自动打开的选择性通风区域，非相变通风区为常通风区域。当使用不点燃加热抽吸方式时，烟气释放端的温度很高，这会使得相变材料融化，此时，第一通风孔自动打开以提高通风量降低抽吸出烟气的温度。当使用点燃方式抽吸时，烟气释放端的温度较低，不会影响抽吸。In the present invention, a phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a first ventilation hole and a second ventilation hole are respectively arranged on the phase-change ventilation area and the non-phase-change ventilation area, and the first ventilation hole is filled with Phase change material, a selective ventilation area that can be automatically opened with temperature changes, and a non-phase change ventilation area is a constant ventilation area. When using the non-ignition heating and smoking method, the temperature of the smoke release end is very high, which will melt the phase change material. At this time, the first ventilation hole is automatically opened to increase the ventilation rate and reduce the temperature of the smoke drawn out. When the ignition method is used for smoking, the temperature of the smoke release end is relatively low, which will not affect the suction.
本发明中的淀粉管一方面具有良好的降温效果，另一方面具有一定的支撑作用，尤其是在使用不点燃加热抽吸方式时，方便烟支的插入。The starch tube in the present invention has a good cooling effect on the one hand, and a certain supporting effect on the other hand, especially when the non-ignited heating and smoking method is used, which facilitates the insertion of cigarettes.
作为本发明的优选方案，所述相变通风区靠近所述烟气进入端或所述非相变通风区靠近烟气进入端。As a preferred solution of the present invention, the phase change ventilation area is close to the flue gas inlet end or the non-phase change ventilation area is close to the flue gas inlet end.
作为优选的技术方案，所述相变通风区靠近所述烟气进入端或所述非相变通风区靠近烟气进入端。当相变通风区靠近烟气进入端时，相变通风区首先感应到温度的变化，有利于控制通风量，降温效果好；当非相变通风区靠近烟气进入端时，这样的结构方便加工制造。但是，无论是以上两种通风区排布方式中的任意一种，都可以实现“一烟两抽”的目的，只是各有偏向而已，或偏向降温效果，或偏向加工制造。As a preferred technical solution, the phase change ventilation area is close to the flue gas inlet end or the non-phase change ventilation area is close to the flue gas inlet end. When the phase change ventilation area is close to the flue gas inlet end, the phase change ventilation area first senses the temperature change, which is beneficial to control the ventilation volume and has a good cooling effect; when the non-phase change ventilation area is close to the flue gas inlet end, such a structure is convenient Manufacturing. However, no matter it is any one of the above two arrangement of ventilation areas, the purpose of "one smoke and two smokes" can be achieved, but each has its own bias, or biased towards cooling effect, or biased towards processing and manufacturing.
作为本发明的优选方案，所述相变通风区与所述烟气进入端的距离不小于所述相变通风区和所述非相变通风区之间的距离；或所述非相变通风区与所述烟气进入端的距离不小于所述相变通风区和所述非相变通风区的距离。As a preferred solution of the present invention, the distance between the phase-change ventilation area and the flue gas inlet end is not less than the distance between the phase-change ventilation area and the non-phase-change ventilation area; or the non-phase-change ventilation area The distance from the inlet end of the flue gas is not less than the distance between the phase-change ventilation area and the non-phase-change ventilation area.
本发明中相变区与其他位置的距离的测量为，以相变区的中心线为起点，以其他位置为终点，这段距离为两者的间距；同样，非相变区的距离测定与相变区一致。In the present invention, the measurement of the distance between the phase transition zone and other positions is that the center line of the phase transition zone is taken as the starting point, and other positions are taken as the end point, and this distance is the distance between the two; similarly, the distance measurement of the non-phase transition zone is the same as The phase transition region is consistent.
这样做的目的主要是为了在不点燃加热抽吸方式中，由于降温段的一部分会插入加热装置，接触到高温烟气，因此对距离的限定可以较好的利用降温段进行降温。The purpose of this is mainly for the purpose of not igniting the heating and pumping method, since a part of the cooling section will be inserted into the heating device and come into contact with the high-temperature flue gas, so the limitation of the distance can make better use of the cooling section for cooling.
作为本发明的优选方案，所述相变材料的相变温度为55～60℃或45～55℃。为了满足烟气进入使用者的体内温度不会过高，避免发生烫嘴的情况，相变材料需要在45～60℃温度范围内的某一条件下发生相变，发生相变的状态可以是融化、收缩，能够满足打开通风区，增加通风量的相变形似均可。相变材料的相变温度决定了烟气进入使用者的感受温度，需要满足在合适的温度范围内融化，进行通风降温才能满足使用者的需求，所以，当相变材料靠近烟气进入端时，相变材料发生相变的温度较高，使用相变温度范围在55～60℃的相变材料较为合适；当相变材料远离烟气进入端时，相变材料发生相变的温度较低，使用相变温度范围在45～55℃的相变材料较为合适。As a preferred solution of the present invention, the phase-change temperature of the phase-change material is 55-60°C or 45-55°C. In order to ensure that the temperature of the flue gas entering the user's body will not be too high and avoid burning the mouth, the phase change material needs to undergo a phase change under a certain condition within the temperature range of 45 to 60 °C. The state of the phase change can be Melting and shrinking, it can meet the requirements of opening the ventilation area and increasing the amount of ventilation. The phase change temperature of the phase change material determines the temperature experienced by the flue gas entering the user. It needs to be melted within a suitable temperature range and ventilated and cooled to meet the needs of the user. Therefore, when the phase change material is close to the flue gas entry end , the phase change temperature of the phase change material is relatively high, and it is more appropriate to use a phase change material with a phase change temperature range of 55 to 60 °C; when the phase change material is far away from the flue gas inlet, the phase change temperature of the phase change material is lower. , it is more appropriate to use a phase change material with a phase change temperature range of 45 to 55 °C.
作为本发明的优选方案，所述相变材料的组成按重量份包括：7～10份淀粉、0.1～1.5份聚乳酸和0.1～1.5份多元醇。As a preferred solution of the present invention, the composition of the phase change material includes, in parts by weight: 7-10 parts of starch, 0.1-1.5 parts of polylactic acid and 0.1-1.5 parts of polyol.
作为本发明的优选方案，所述淀粉为玉米淀粉、马铃薯淀粉、紫薯淀粉和百合淀粉中的一种或几种，其中所述玉米淀粉、马铃薯淀粉、紫薯淀粉和百合淀粉的粒径均在10～100μm范围内。As a preferred version of the present invention, the starch is one or more of corn starch, potato starch, purple potato starch and lily starch, wherein the corn starch, potato starch, purple potato starch and lily starch have a uniform particle size in the range of 10 to 100 μm.
作为本发明的优选方案，所述聚乳酸的分子量为20000～80000。As a preferred solution of the present invention, the molecular weight of the polylactic acid is 20,000-80,000.
相变材料采用全降解生物材料组成，具有高的环保价值；多元醇的加入使材料软化，流动性提升，这样更利于打开相变通风区。相变通风区的通风依赖于第一通风孔的打开，第一通风孔的具体打开方式为：相变材料接触高温烟气，发生相变，与此同时，由于抽吸在相变材料中心处压强较大，相变材料的状态由封闭变成逐渐由中心向两边的开口，这样便实现了相变通风区随温度的升高而增加通风量的过程。The phase change material is composed of fully degradable biological materials, which has high environmental protection value; the addition of polyols softens the material and improves the fluidity, which is more conducive to opening the phase change ventilation area. The ventilation of the phase change ventilation area depends on the opening of the first ventilation hole. The specific opening method of the first ventilation hole is as follows: the phase change material contacts the high temperature flue gas and undergoes a phase change. At the same time, due to the suction at the center of the phase change material When the pressure is large, the state of the phase change material changes from being closed to gradually opening from the center to both sides, thus realizing the process of increasing the ventilation volume in the phase change ventilation area with the increase of temperature.
此处，给出本发明所采用的相变材料的重量配比，具体为：7.0～10.0份淀粉、0.1～1.5份相变材料、0.1～1.5份多元醇。其中，淀粉可以为玉米淀粉、马铃薯淀粉、紫薯淀粉、百合淀粉中的一种或几种，粒径范围在10μm～100μm；多元醇为丙二醇或丙三醇中的一种或两种。为了满足随温度的变化相变材料及时改变通风量，相变材料的厚度大小取决于材料的耐温性能，不同的材料耐温性能有差异，总体而言相变材料太厚打开孔需要的热量更多，因此，所述相变材料的厚度最好在50～500μm范围内。Here, the weight ratio of the phase change material used in the present invention is given, specifically: 7.0-10.0 parts of starch, 0.1-1.5 parts of phase-change material, and 0.1-1.5 parts of polyol. Wherein, the starch can be one or more of corn starch, potato starch, purple potato starch, and lily starch, and the particle size ranges from 10 μm to 100 μm; the polyol is one or both of propylene glycol or glycerol. In order to satisfy the change of the ventilation volume of the phase change material with the change of temperature, the thickness of the phase change material depends on the temperature resistance of the material, and the temperature resistance of different materials is different. In general, the phase change material is too thick to open the hole. More, therefore, the thickness of the phase change material is preferably in the range of 50-500 μm.
作为本发明的优选方案，当仅第二通风孔进行通风时，所述烟支总通风率在30～60％范围内；当第一通风孔和第二通风孔同时通风时，所述烟支总通风率不低于70％。这样既保证烟支在点燃抽吸情况下合适的通风率，保证好的抽吸体验，而且在加热不燃烧情况下抽吸时，能增大通风，使得较热的烟气和滤嘴表面的温度能够得到有效下降。如果第一通风孔和第二通风孔都为通风孔结构且均匀分布在包覆层上，这些通风孔的数量、孔径大小、排布方式均可以根据实际需要予以调整，以满足烟支对通风率要求。但是，实验研究发现，在烟支靠近烟气释放端不同距离处，通风率可以做到一致，但是降温效果还跟烟支结构、材料以及配套加热器的设计有关，因此通过合理设置通孔的位置，结合烟支、配套加热器设计，也是可以实现降温效果的。值得注意的是，烟支随着燃烧的进行，滤嘴端的温度也是逐渐升高的，在点燃抽吸到后端，第一通孔有被打开的可能到导致抽吸时气流更多地进入滤嘴稀释烟气和降低烟气温度，能保证抽吸口感的一致性。作为更优选的技术方案，所述相变通风区与所述烟气进入端的距离小于所述相变通风区和所述非相变通风区之间的距离，这样的布置有利于烟气口感的提升。As a preferred solution of the present invention, when only the second ventilation holes are ventilated, the total ventilation rate of the cigarettes is in the range of 30-60%; when the first ventilation holes and the second ventilation holes are ventilated at the same time, the cigarettes are ventilated at the same time. The total ventilation rate is not less than 70%. This not only ensures a proper ventilation rate when the cigarette is lit and smoked, and ensures a good smoking experience, but also increases the ventilation when smoking under the condition of heating and not burning, so that the hot smoke and the surface of the filter tip are not affected. The temperature can be effectively lowered. If both the first ventilation holes and the second ventilation holes are in the structure of ventilation holes and are evenly distributed on the cladding layer, the number, aperture size and arrangement of these ventilation holes can be adjusted according to actual needs to meet the needs of cigarettes for ventilation. rate requirements. However, experimental studies have found that the ventilation rate can be consistent at different distances between the cigarette and the smoke release end, but the cooling effect is also related to the structure, material and design of the matching heater. The location, combined with the design of the cigarette and the matching heater, can also achieve the cooling effect. It is worth noting that as the cigarette burns, the temperature of the filter tip also increases gradually. When the cigarette is ignited and sucked to the rear end, the first through hole may be opened, causing more airflow to enter during smoking. The filter tip dilutes the smoke and reduces the temperature of the smoke, which can ensure the consistency of the smoking taste. As a more preferred technical solution, the distance between the phase-change ventilation area and the smoke inlet end is smaller than the distance between the phase-change ventilation area and the non-phase-change ventilation area, and such an arrangement is conducive to improving the taste of smoke. promote.
为了实现上述滤嘴的应用，尤其面对日新月异的烟草变革时代，本发明还提供了：In order to realize the application of the above-mentioned filter tip, especially in the face of the ever-changing tobacco revolution era, the present invention also provides:
一种包括上述滤嘴的卷烟，既可以使用传统的点燃抽吸的方式，也可以使用不点燃加热抽吸方式。A cigarette comprising the above filter tip can use either a traditional lit smoking method or a non-lit heating smoking method.
本发明中，所述卷烟还包括烟草段，所述滤嘴连接所述烟草段。In the present invention, the cigarette further includes a tobacco segment, and the filter tip is connected to the tobacco segment.
相比于现有技术，本发明的有益效果为：Compared with the prior art, the beneficial effects of the present invention are:
本发明在包覆层设置相变通风区和非相变通风区，在相变通风区和非相变通风区上分别设有第一通风孔和第二通风孔，第一通风孔内填充有相变材料，可随温度变化自动打开的选择性通风区域，非相变通风区为常通风区域。当使用不点燃加热抽吸方式时，烟气释放端的温度很高，这会使得相变材料融化，此时，第一通风孔自动打开以提高通风量降低抽吸出烟气的温度。当使用点燃方式抽吸时，烟气释放端的温度较低，不会影响抽吸。In the present invention, a phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a first ventilation hole and a second ventilation hole are respectively arranged on the phase-change ventilation area and the non-phase-change ventilation area, and the first ventilation hole is filled with Phase change material, a selective ventilation area that can be automatically opened with temperature changes, and a non-phase change ventilation area is a constant ventilation area. When using the non-ignition heating and smoking method, the temperature of the smoke release end is very high, which will melt the phase change material. At this time, the first ventilation hole is automatically opened to increase the ventilation rate and reduce the temperature of the smoke drawn out. When the ignition method is used for smoking, the temperature of the smoke release end is relatively low, which will not affect the suction.

如图1～5所示，本实施例提供了一种可变通风量的滤嘴，包括滤芯1和包覆层2，包覆层2包裹住滤芯1；滤芯1包括烟气进入端11和烟气释放端12；包覆层2上设有相变通风区21和非相变通风区22，相变通风区21上设有多个第一通风孔212，非相变通风区22上设有多个第二通风孔221；外界空气通过第一通风孔212和第二通风孔221分别穿过包覆层2深入至部分滤芯13；第一通风孔212内填充有相变材料211；所述滤芯内靠近所述烟气进入端的部分设有淀粉管14，淀粉管14设有中空腔15；相变材料211的相变温度范围为45～60℃。As shown in Figures 1-5, the present embodiment provides a filter tip with a variable ventilation rate, including a
第一通风孔212的具体打开方式为：相变材料211接触高温烟气，发生相变，与此同时，抽吸力使得相变材料211在中心处压强较大，相变材料211的状态由封闭变成逐渐由中心向两边的开口，这样便实现了相变通风区随温度的升高而增加通风量的过程。The specific opening method of the
当相变通风区21靠近烟气进入端11时，相变通风区21首先感应到温度的变化，有利于控制通风量，降温效果好，此时的相变材料211的相变温度范围是55～60℃；当非相变通风区221靠近烟气进入端时，相变材料211的相变温度范围是45～55℃，相对较低，并且这样的结构方便加工制造。但是，无论是以上两种通风区排布方式中的任意一种，都可以实现“一烟两抽”的目的，只是各有偏向而已，或偏向降温效果，或偏向加工制造。本实施例中，相变通风区21与烟气进入端11的距离不小于相变通风区21和非相变通风区22之间的距离，这样的布置有利于烟气口感的提升。这种情况下相变材料211在55℃条件下发生相变以增加通风量，通风率为80％。When the phase
包覆层2设有相变通风区21和非相变通风区22，相变通风区21上设有相变材料211。本实施例中，相变通风区21上均匀设有若干第一通风孔212，第一通风孔212内填充相变材料211，通风孔结构容易加工，在孔内填充相变材料211一方面不会增加包覆层2的厚度，使得滤嘴自然美观，另一方面相变材料211在孔内的结合程度高，不容易脱落。非相变通风区22上均匀设有第二通风孔221。The
相变材料211能够在45～60℃温度条件下发生相变。相变材料211的相变温度决定了烟气进入使用者的感受温度，需要满足在合适的温度范围内融化，进行通风降温才能满足使用者的需求，所以，使用相变温度范围在50～55℃的相变材料较为合适。本实施例中，相变温度为50～55℃，采用的相变材料组成包括淀粉、聚乳酸和多元醇，具有方便结合，易流通的优势。为了满足随温度的变化相变材料及时改变通风量，相变材料的厚度不能太厚，本实施例中，相变材料的厚度为50～500μm，具体在本实施例中相变材料的厚度为300μm。并且当仅非相变通风区22进行通风时，烟支总通风率在30～60％范围内；当相变通风区21和非相变通风区22同时通风时，滤嘴的通风率不低于70％，这样的结构可以提供更好的、更稳定的烟气口感。如果相变通风区21和非相变通风区22都为通风孔结构且均匀分布在包覆层2上，如果相变通风区和非相变通风区都为通风孔结构且均匀分布在包覆层上，这些通风孔的数量、孔径大小、排布方式均可以根据实际需要予以调整，以满足烟支对通风率要求。通过第一通风孔位置的调整，还能起到烟气降温的效果。The
一种应用上述滤嘴的卷烟，既可以用于传统的点燃抽吸方式，同时也适用于不点燃加热抽吸方式。A cigarette using the above-mentioned filter tip can be used not only in a traditional lit smoking method, but also in a non-lit heating smoking method.
本发明中，所述卷烟还包括烟草段，所述滤嘴连接所述烟草段。In the present invention, the cigarette further includes a tobacco segment, and the filter tip is connected to the tobacco segment.
本发明的工作原理为：The working principle of the present invention is:
当以点燃的方式抽吸卷烟时，相变通风区21保持关闭状态；非相变通风区22增加了一定的通风量，足以降低烟丝释放进入人体的温度。当以不燃烧加热方式抽吸卷烟时，烟气进入滤嘴的温度较点燃方式抽吸时的温度高，此时相变通风区21的相变材料211发生相变，打开相变通风区21，增加通风量，此时烟支总通风率可达70％以上。When the cigarette is smoked by lighting, the phase-
实施例2Example 2
如图4所示，本实施例为本发明的第二个实施例，该实施例基本与实施例1相同，不同之处在于，非相变通风区22靠近烟气进入端11，并且非相变通风区22与烟气进入端11之间的距离不小于相变通风区21与非相变通风区22之间的距离。此时，相变材料211在50℃条件下发生相变以增加通风量，烟支总通风率为75％。As shown in FIG. 4 , this embodiment is the second embodiment of the present invention. This embodiment is basically the same as
