Description
本发明涉及加热不燃烧烟支领域，具体涉及一种加热不燃烧型烟具的底托及使用该底托的烟具。The invention relates to the field of heat-not-burn cigarettes, in particular to a base holder of a heat-not-burn smoking set and a smoking set using the base support.
近些年来，加热不燃烧型烟支自出现在烟支消费市场上以来，广受消费者的关注，其市场占比逐年增高。所谓“加热不燃烧型烟支”，就是仅对烟支进行加热而不使其燃烧，其加热温度明显低于烟支燃点，因此，加热不燃烧型烟支需要将加热器与烟支配合使用，烟支由烟草及其衍生物构成，加热器即为烟具。
在烟具中，加热腔用于对位于其中的烟支进行加热，其通过电转化产生加热升温，发热原理可以采用电加热元件直接通电加热，也可以采用电磁感应元件进行电磁感应加热。目前，电子加热元件的型式可以采用筒壁型对烟支进行侧壁加热，也可以采用插入型在烟支内部进行中央加热。无论采用哪种加热方式，烟具中的加热腔都要保持空气贯通，以确保实现抽吸效应，因此，烟具内与烟支直接接触的结构中必须有通气孔保证空气体流通。在使用过程中，空气会随使用者的抽吸，通过通气孔进入加热腔且流经烟支，在此过程中混合烟支中的香味物质，从而形成香气味浓郁的烟气，并随着使用者的吸气进入口腔。
烟具直接接触并作用于烟支的结构，可以通过底托和/或侧面夹套来保持固定烟支。一般来说，侧面夹套与底托一同作用，侧面夹套可以保证烟支在烟具中处于竖直状态而不发生倾斜，底托可以保证烟支在烟具中的高度，以使烟支在烟具内固定就位，从而使烟支稳定地处于有效的加热范围内，以确保有效地实现加 热功能。
为了实现空气在烟支中贯穿流通，必须在底托的底部中心位置处开设通孔。一般来说，通孔的形状与插入型加热元件横截面的形状相同，例如，对于针型加热元件而言，通孔形状为圆形，对于片型加热元件而言，通孔的形状为线形。但是，由于与完全暴露于空气环境中的传统卷烟不同，加热不燃烧型烟支的透气度明显低于传统卷烟，以致使用者在使用时需付出更大的抽吸力进行抽吸。这意味着，在每次抽吸加热不燃烧型烟支时，烟气的气体流通速度明显快于普通卷烟抽吸时的气体流通速度，从而导致加热不燃烧型烟支的空气转化为烟气的速度更快，由此造成加热不燃烧型烟支的气体附着香气的时间较短，烟气中香气味物质成分较低，从而降低了抽吸烟气的愉悦度，难以达到理想的抽吸效果。In recent years, heat-not-burn cigarettes have attracted the attention of consumers since they appeared in the cigarette consumption market, and their market share has increased year by year.

为了解决以上现有技术中存在的加热不燃烧型烟支抽吸效果不理想的缺陷，本发明的目的在于提供一种加热不燃烧型烟具的底托及使用该底托的烟具，其能够明显改善加热不燃烧型烟支的抽吸效果，在抽吸过程中为使用者提供均匀、饱满的香气，显著提升加热不燃烧型烟支抽吸的愉悦感受。
根据本发明的一个方面，提供了一种加热不燃烧型烟具的底托，其底部设有通孔，其中，底托通孔的形状与插入型加热元件横截面的形状不同。
优选的是，底托通孔的形状为非中心对称形状。
优选的是，烟具的底托通孔形状为异形或不规则形状。
优选的是，烟具的底托通孔形状为月形。
优选的是，底托通孔形状的面积远大于插入型加热元件所需的插入孔面积， 以使底托通孔与插入型加热元件之间保持足够的通气间隙。更优选的是，底托通孔的面积为插入型加热片最大横截面面积的2倍以上。
根据本发明的另一个方面，提供了一种加热不燃烧型烟具，其特征在于：该烟具设有上面所述的底托。
烟具的底托用于固定烟支的位置，使烟支稳定处于有效加热范围内，从而实现加热元件对烟支进行均匀加热，与此同时，在烟具底托上设置通孔即构成烟支的空气输入口。在目前的加热不燃烧型烟具中，其底托通孔均是以底托的中心为中心，并且，其形状为规则标准形状。具体而言，对于筒壁型加热元件而言，通孔的形状为圆形；对于针型加热元件而言，烟具的底托形状为圆形，如图3所示；对于片型加热元件而言，烟具的底托形状为相应的线形，如图4所示。发明人经研究发现，现有技术中，目前所谓标准的底托通孔形状不利于改善流经加热不燃烧型烟支的空气流通状况，以致产生通孔面积小、进气量小、烟气浓度低，香气味成分利用率低、烟支中最重要的烟料成分作用不完全、抽吸口感不均匀等不良状况。
针对于此，发明人对底托通孔的形状作出了改进，即，使底托通孔的形状形成非中心对称形状。经研究发现，这一改进能够产生显著的有益技术效果。即，能够实现空气经底托通孔进入烟支时呈现出非均匀流量的输送状态。更具体地说，由于底托通孔的形状不同于插入型加热元件横截面的形状，且底托通孔为非中心对称形状，因此，底托通孔的面积也呈非对称状态分布。由于在底托通孔面积较大的一侧，空气的流量更大，因此，能够使烟支中这一侧发烟物质的香气味物质流失速度更快。这样，一旦启动使用加热不燃烧型烟支后，在加热元件对烟支持续加热的过程中，底托通孔面积较小一侧的发烟物质的香气味物质流失速度 慢于底托通孔面积较大的一侧，这样，在使用者抽吸过程中，烟支中底托通孔面积较小一侧的香气味物质能够与流经烟支的空气更充分混合而累积增浓，从而有助于抽吸者获得较为浓郁的烟气；在使用者下一次抽吸时，由于底托通孔面积较大一侧的香气味物质还未在短时间内充分散发出来，而另一侧储存的大量烟气会优先被供给抽吸，由此能够保证烟支中的香气味物质不断聚集且交替输送，实现多次抽吸始终保持高质量抽吸口感，减小每次抽吸时口感方面所存在的差异，从而在烟支一旦被启动多次抽吸的过程中，能够确保烟气量、烟气状态统一，抽吸感受始终一致，抽吸口感均匀，消除了在抽吸现有加热不燃烧型烟支时存在的“某一口好抽”、“某一口不好抽”、“抽吸过程中出现抽吸感受差异”、“越抽越不好抽”等不良情况。In order to solve the disadvantages of the unsatisfactory smoking effect of heat-not-burn cigarettes in the prior art, the purpose of the present invention is to provide a bottom bracket for a heat-not-burn smoking set and a smoking set using the bottom bracket, which can clearly Improve the smoking effect of heat-not-burn cigarettes, provide users with a uniform and full aroma during the smoking process, and significantly improve the pleasurable feeling of smoking heat-not-burn cigarettes.
According to one aspect of the present invention, there is provided a base of a heat-not-burn smoking appliance, the bottom of which is provided with a through hole, wherein the shape of the through hole of the base is different from that of the cross-section of the inserted heating element.
Preferably, the shape of the bottom bracket through hole is non-centrosymmetric.
Preferably, the shape of the through hole of the base of the smoking appliance is irregular or irregular.
Preferably, the through hole of the base of the smoking set is moon-shaped.
Preferably, the area of the shape of the through-hole of the bottom support is much larger than the area of the insertion hole required by the insertion-type heating element, so as to maintain a sufficient ventilation gap between the through-hole of the bottom support and the insertion-type heating element. More preferably, the area of the bottom support through hole is more than twice the maximum cross-sectional area of the insert-type heating sheet.
According to another aspect of the present invention, a heat-not-burn smoking appliance is provided, which is characterized in that: the smoking appliance is provided with the above-mentioned bottom support.
The bottom bracket of the smoking set is used to fix the position of the cigarette, so that the cigarette is stably within the effective heating range, so that the heating element can evenly heat the cigarette. At the same time, the through hole is set on the bottom bracket of the smoking set to form the cigarette Air inlet. In current heat-not-burn smoking appliances, the through-holes of the bottom support are all centered on the center of the bottom support, and the shape is a regular standard shape. Specifically, for the tube-type heating element, the shape of the through hole is circular; for the needle-type heating element, the shape of the base of the smoking appliance is circular, as shown in Figure 3; for the sheet-type heating element, In other words, the shape of the base of the smoking set is a corresponding linear shape, as shown in Figure 4. The inventor found through research that in the prior art, the so-called standard shape of the through hole of the bottom bracket is not conducive to improving the air circulation condition of the heat-not-burn cigarette, so that the area of the through hole is small, the air intake volume is small, and the smoke Low concentration, low utilization rate of aroma components, incomplete effect of the most important tobacco material components in cigarettes, uneven smoking taste and other adverse conditions.
In view of this, the inventor has improved the shape of the through hole of the bottom bracket, that is, the shape of the through hole of the bottom bracket is formed into a non-centrosymmetric shape. It is found through research that this improvement can produce significant beneficial technical effects. That is to say, it is possible to realize the conveying state in which the air presents a non-uniform flow rate when it enters the cigarette through the through hole of the base holder. More specifically, since the shape of the through hole of the bottom support is different from the shape of the cross section of the insertion type heating element, and the through hole of the bottom support is non-centrosymmetric, the area of the through hole of the bottom support is also distributed asymmetrically. Since the air flow is larger on the side with a larger through-hole area of the bottom support, the aroma and smell substances of the smoking substance in the cigarette can be lost faster on this side. In this way, once the heat-not-burn cigarette is started to be used, in the process of the heating element continuing to heat the cigarette holder, the loss rate of the aroma and smell of the smoking substance on the side with the smaller through-hole area of the bottom holder is slower than that through the through-hole of the bottom holder In this way, during the user's inhalation process, the aroma substances on the side with the smaller through-hole area in the bottom support of the cigarette can be more fully mixed with the air flowing through the cigarette and accumulate and increase in concentration, thereby It helps the smoker to obtain a relatively dense smoke; when the user smokes next time, the aroma substances on the side with the larger through-hole area of the bottom bracket have not been fully emitted in a short time, while the other side A large amount of stored smoke will be given priority to suction, thus ensuring the continuous accumulation and alternate delivery of aroma substances in cigarettes, achieving multiple puffs and always maintaining high-quality puffing taste, reducing the taste of each puff Therefore, once the cigarette is activated for multiple times, it can ensure that the smoke volume and smoke state are uniform, the smoking experience is always consistent, and the smoking taste is even, eliminating the need for inhalation. When heating non-burning cigarettes, there are adverse situations such as "a certain puff is easy to smoke", "a certain puff is not easy to smoke", "differences in puffing experience during the puffing process", "the more you puff, the harder it is to puff".

烟具的底托用于固定烟支的位置，使烟支稳定处于有效加热范围内，从而实现加热元件对烟支进行均匀加热，与此同时，在烟具底托上设置通孔即构成烟支的空气输入口。在目前的加热不燃烧型烟具中，其底托通孔均是以底托的中心为中心，并且，其形状为规则标准形状。具体而言，对于筒壁型加热元件而言，通孔的形状为圆形；对于针型加热元件而言，烟具的底托形状为圆形，如图3所示；对于片型加热元件而言，烟具的底托形状为相应的线形，如图4所示。发明人经研究发现，现有技术中，目前所谓标准的底托通孔形状不利于改善流经加热不燃烧型烟支的空气流通状况，以致产生通孔面积小、进气量小、烟气浓度低，香气味成分利用率低、烟支中最重要的烟料成分作用不完全、抽吸口感不均匀等不良状况。
针对于此，发明人对底托通孔的形状作出了改进，即，使底托通孔的形状形成非中心对称形状。经研究发现，这一改进能够产生显著的有益技术效果。即，能够实现空气经底托通孔进入烟支时呈现出非均匀流量的输送状态。更具体地说，由于底托通孔的形状不同于插入型加热元件横截面的形状，且底托通孔为非中心对称形状，因此，底托通孔的面积也呈非对称状态分布。由于在底托通孔面积较大的一侧，空气的流量更大，因此，能够使烟支中这一侧发烟物质的香气味物质流失速度更快。这样，一旦启动使用加热不燃烧型烟支后，在加热元件对烟支持续加热的过程中，底托通孔面积较小一侧的发烟物质的香气味物质流失速度 慢于底托通孔面积较大的一侧，这样，在使用者抽吸过程中，烟支中底托通孔面积较小一侧的香气味物质能够与流经烟支的空气更充分混合而累积增浓，从而有助于抽吸者获得较为浓郁的烟气；在使用者下一次抽吸时，由于底托通孔面积较大一侧的香气味物质还未在短时间内充分散发出来，而另一侧储存的大量烟气会优先被供给抽吸，由此能够保证烟支中的香气味物质不断聚集且交替输送，实现多次抽吸始终保持高质量抽吸口感，减小每次抽吸时口感方面所存在的差异，从而在烟支一旦被启动多次抽吸的过程中，能够确保烟气量、烟气状态统一，抽吸感受始终一致，抽吸口感均匀，消除了在抽吸现有加热不燃烧型烟支时存在的“某一口好抽”、“某一口不好抽”、“抽吸过程中出现抽吸感受差异”、“越抽越不好抽”等不良情况。In order to solve the disadvantages of the unsatisfactory smoking effect of heat-not-burn cigarettes in the prior art, the purpose of the present invention is to provide a bottom bracket for a heat-not-burn smoking set and a smoking set using the bottom bracket, which can clearly Improve the smoking effect of heat-not-burn cigarettes, provide users with a uniform and full aroma during the smoking process, and significantly improve the pleasurable feeling of smoking heat-not-burn cigarettes.
According to one aspect of the present invention, there is provided a base of a heat-not-burn smoking appliance, the bottom of which is provided with a through hole, wherein the shape of the through hole of the base is different from that of the cross-section of the inserted heating element.
Preferably, the shape of the bottom bracket through hole is non-centrosymmetric.
Preferably, the shape of the through hole of the base of the smoking appliance is irregular or irregular.
Preferably, the through hole of the base of the smoking set is moon-shaped.
Preferably, the area of the shape of the through-hole of the bottom support is much larger than the area of the insertion hole required by the insertion-type heating element, so as to maintain a sufficient ventilation gap between the through-hole of the bottom support and the insertion-type heating element. More preferably, the area of the bottom support through hole is more than twice the maximum cross-sectional area of the insert-type heating sheet.
According to another aspect of the present invention, a heat-not-burn smoking appliance is provided, which is characterized in that: the smoking appliance is provided with the above-mentioned bottom support.
The bottom bracket of the smoking set is used to fix the position of the cigarette, so that the cigarette is stably within the effective heating range, so that the heating element can evenly heat the cigarette. At the same time, the through hole is set on the bottom bracket of the smoking set to form the cigarette Air inlet. In current heat-not-burn smoking appliances, the through-holes of the bottom support are all centered on the center of the bottom support, and the shape is a regular standard shape. Specifically, for the tube-type heating element, the shape of the through hole is circular; for the needle-type heating element, the shape of the base of the smoking appliance is circular, as shown in Figure 3; for the sheet-type heating element, In other words, the shape of the base of the smoking set is a corresponding linear shape, as shown in Figure 4. The inventor found through research that in the prior art, the so-called standard shape of the through hole of the bottom bracket is not conducive to improving the air circulation condition of the heat-not-burn cigarette, so that the area of the through hole is small, the air intake volume is small, and the smoke Low concentration, low utilization rate of aroma components, incomplete effect of the most important tobacco material components in cigarettes, uneven smoking taste and other adverse conditions.
In view of this, the inventor has improved the shape of the through hole of the bottom bracket, that is, the shape of the through hole of the bottom bracket is formed into a non-centrosymmetric shape. It is found through research that this improvement can produce significant beneficial technical effects. That is to say, it is possible to realize the conveying state in which the air presents a non-uniform flow rate when it enters the cigarette through the through hole of the base holder. More specifically, since the shape of the through hole of the bottom support is different from the shape of the cross section of the insertion type heating element, and the through hole of the bottom support is non-centrosymmetric, the area of the through hole of the bottom support is also distributed asymmetrically. Since the air flow is larger on the side with a larger through-hole area of the bottom support, the aroma and smell substances of the smoking substance in the cigarette can be lost faster on this side. In this way, once the heat-not-burn cigarette is started to be used, in the process of the heating element continuing to heat the cigarette holder, the loss rate of the aroma and smell of the smoking substance on the side with the smaller through-hole area of the bottom holder is slower than that through the through-hole of the bottom holder In this way, during the user's inhalation process, the aroma substances on the side with the smaller through-hole area in the bottom support of the cigarette can be more fully mixed with the air flowing through the cigarette and accumulate and increase in concentration, thereby It helps the smoker to obtain a relatively dense smoke; when the user smokes next time, the aroma substances on the side with the larger through-hole area of the bottom bracket have not been fully emitted in a short time, while the other side A large amount of stored smoke will be given priority to suction, thus ensuring the continuous accumulation and alternate delivery of aroma substances in cigarettes, achieving multiple puffs and always maintaining high-quality puffing taste, reducing the taste of each puff Therefore, once the cigarette is activated for multiple times, it can ensure that the smoke volume and smoke state are uniform, the smoking experience is always consistent, and the smoking taste is even, eliminating the need for inhalation. When heating non-burning cigarettes, there are adverse situations such as "a certain puff is easy to smoke", "a certain puff is not easy to smoke", "differences in puffing experience during the puffing process", "the more you puff, the harder it is to puff".

其中：100-烟具；101-底托；102-加热元件；103-底座；200-烟支Among them: 100-smoking set; 101-bottom bracket; 102-heating element; 103-base; 200-cigarette stick
下面，将结合附图对本发明进行详细说明。Below, the present invention will be described in detail with reference to the accompanying drawings.
以加热元件为插入型的烟具为例，作为保持烟支200的底托101，在本实施例中，其通孔形采用了图5所示的月形形状。并且，如图5所示，这种月形形状，实际为在中心通孔的基础上增设扇形通孔。通过图5与图3，图4对比明确可知，底托101的通孔形状的面积远大于插入型加热元件所需的插入孔面积。由于烟具100采用了这种特殊形状的通孔，其中心通孔部分能够保证加热元件顺利插入，增设的扇形通孔能够显著大大空气流量，扇形弧度越大，通孔面积也就越大，增加的空气流量也就越大，改善空气流通烟支的效果也就越好，从而实现多次抽吸始终保持高质量抽吸口感，减小每次抽吸时口感方面所存在的差异。在烟支被启动多次抽吸的过程中，能够确保烟气量、烟气状态统一，抽吸感受始终一致，抽吸口感均匀。当然，由于底托的承托功能特征，扇形夹角小于360°。Taking a smoking appliance with an inserting heating element as an example, as the base 101 holding the cigarette 200, in this embodiment, the shape of the through hole adopts the moon shape as shown in FIG. 5 . Moreover, as shown in FIG. 5 , this moon shape is actually a fan-shaped through hole added on the basis of the central through hole. From the comparison of FIG. 5 with FIG. 3 and FIG. 4 , it can be clearly seen that the area of the through-hole shape of the base 101 is much larger than the area of the insertion hole required by the insertion-type heating element. Since the smoking set 100 adopts this special-shaped through hole, the central through hole part can ensure the smooth insertion of the heating element, and the additional fan-shaped through hole can significantly increase the air flow rate. The larger the fan-shaped arc, the larger the through-hole area, increasing The greater the air flow rate, the better the effect of improving the air circulation of the cigarette, so that the high-quality smoking taste can be maintained for multiple puffs, and the difference in the taste of each puff can be reduced. During the process of smoking a cigarette for multiple times, it can ensure that the smoke volume and smoke state are uniform, the puffing experience is always consistent, and the puffing taste is uniform. Of course, due to the supporting function of the bottom bracket, the fan-shaped included angle is less than 360°.
试验进一步证明，例如，特别是将底托通孔的面积设定为插入型加热片最大横截面面积的2倍以上，能够进一步增加改善空气流通烟支的效果。Tests have further proved that, for example, setting the area of the through hole of the bottom holder to more than twice the maximum cross-sectional area of the insert-type heating sheet can further increase the effect of improving the air circulation of the cigarette.
以上内容仅仅是本发明的最佳实施例。应强调的是，在不脱离本发明构思的前提下，本领域普通技术人员对本发明所作的各种变型和改进均应落入本发明的保护范围内。The above are only the preferred embodiments of the present invention. It should be emphasized that, on the premise of not departing from the concept of the present invention, various modifications and improvements made by those skilled in the art to the present invention shall fall within the protection scope of the present invention.
