在本实施方式中，所述第二降温部60设于所述第一降温部40与所述过滤部50之间，以对所述气溶进进一步降温。所述第二降温部60为降温材料，且所述第二降温部60用于加速降低高温的气溶胶的温度，使得高温的气溶胶在流经所述第二降温部60后，温度能够快速降低至适宜的抽吸温度(例如40℃等)。具体地，所述第二降温部60为食用级的降温材料，能够在受热时减少甚至不产生有毒物。在本实施方式中，所述第二降温部60可以为任意形状，举例而言，所述第二降温部60可以但不限于为颗粒状、条状或者块状等形状，只要所述第二降温部60能够填充至所述管体10中，并起到降温的作用即可。
本申请提供了一种加热不燃烧烟弹1，所述加热不燃烧烟弹1包括管体10、封口部20、发烟部30、第一降温部40、过滤部50及第二降温部60。所述管体10具有相背设置的第一端11及第二端12。所述封口部20用于密封所述第一端11。所述发烟部30收容于所述管体10，且所述发烟部30邻近所述第一端11设置。所述第一降温部40收容于所述管体10，且邻近所述发烟部30设置第一降温部40。所述过滤部50收容于所述管体10，且设置于所述第二端12。所述第二降温部60设于所述第一降温部40及所述过滤部50之间。所述发烟部30受热后产生的高温气溶胶会先后流经所述第一降温部40及所述第二降温部60，在流经所述第一降温部40及所述第二降温部60之后所述气溶胶迅速降温至适宜的抽吸温度，以提高用户的抽吸体验。因此，本申请提供的加热不燃烧烟弹1能够通过所述第一降温部40及所述第二降温部60将所述发烟部30受热产生的高温气溶胶快速降低至适宜的抽吸温度。
请再次参照图3，在本实施方式中，所述过滤部50与所述第一降温部40形成收容腔70，所述收容腔70用于收容所述第二降温部60，所述第二降温部60与所述收容腔70的体积比a的范围为：20％≦a≦60％。
在本实施方式中，所述第二降温部60占所述收容腔70体积比a的范围为：20％≦a≦60％，能够在保有所述第二降温部60的降温效率的情况下，使得所述加热不燃烧烟弹1具有适宜的抽吸阻力。如若所述第二降温部60占所述收容腔70的体积比a过大，则会增加气溶胶通过所述收容腔70的阻力，从了使得抽吸阻力过大。如若所述第二降温部60占所述收容腔70的体积比a过小，则会降低所述第二降温部60与气溶胶的接触面积，从而降低了所述第二降温部60的降温效果。
请再次参照图3，在本实施方式中，所述收容腔70在所述第一端11指向所述第二端12的方向上的长度L1与所述管体10的长度L0的比为：20％≤L1/L0≤30％。
在本实施方式中，所述收容腔70用于容纳所述发烟部30受热产生的气溶胶。所述发烟部30受热产生的气溶胶经过所述降温部降温后流入所述收容腔70，并聚集于所述收容腔70，最后所述气溶胶经由所述过滤部50被用户吸食。由于所述气溶胶可以在所述收容腔70中聚集，以形成一定浓度的气溶胶，从而可以提高经过所述过滤部50的气溶胶浓度，即提高了用户吸食气溶胶的浓度。
具体地，所述收容腔70需要具有一定的长度，提供足够的空间容纳气溶胶以提高所述气溶胶的浓度。在所述管体10的长度L0保持一定时，所述收容腔70的长度L1会影响所述发烟部30的装填长度L2，即如若所述收容腔70的长度L1过长，则会使得所述发烟部30的装填长度L3过小，从而影响所述发烟部30的发烟量，降低了所述加热不燃烧烟弹1的吸食体验。因此，所述收容腔70需要保持适宜长度，具体地，所述收容腔70在所述第一端11指向所述第二端12的方向上的长度L1与所述管体10的长度L0的比为：20％≤L1/L0≤30％，所述收容腔70既能容纳气溶胶以提高气溶胶的吸食浓度，又能使得所述管体10留有足够空间装填所述发烟部30，以保证所述发烟部30的发烟量。
请参照图4，图4为图1实施方式提供的加热不燃烧烟弹另一实施方式中沿线A-A的剖面示意图；图5为图4实施方式提供的加热不燃烧烟弹在第一状态下的结构示意图；图6为图4实施方式提供的加热不燃烧烟弹在第二状态下的结构示意图。在本实施方式中，所述第一降温部40具有相背设置的第一收容空间41及第二收容空间42，所述第一收容空间41相对于所述第二收容空间42靠近所述发烟部30设置，且所述发烟部30可进入所述第一收容空间41。
在本实施方式中，所述第一收容空间41用于为所述发烟部30提供活动空间，以防止所述发烟部30受挤压时，所述发烟部30密度变大，从而导致所述发烟部30内部气隙变小，从而增大了所述加热不燃烧烟弹1的吸阻，影响用户使用。具体地，当对所述加热不燃烧烟弹1进行加热时，需要将所述加热不燃烧烟弹1插入烟具中，以使得烟具中的加热部件(例如，加热针或加热片等)插入所述发烟部30中，由于所述加热部件具有一定的体积，会对所述发烟部30造成挤压，所述发烟部30会受到挤压而部分进入所述第一收容空间41，部分填充或全部填满所述第一收容空间41，从而避免了所述气溶胶生成基质因受挤压而导致吸阻过大。具体地，所述第一收容空间41的体积为30mm 3～35mm 3，优选地为44mm 3～48.5mm 3，以使得所述第一收容空间41为所述发烟部30提供了足够的活动空间，从而避免所述发烟部30受到挤压而使得内部间隙变小。
在本实施方式中，当所述加热不燃烧烟弹1制备完成时，所述加热不燃烧烟弹1处于第一状态(请参见图5)，所述发烟部30全部处于所述第一收容空间41外部。当所述加热不燃烧烟弹1插入烟具中时，所述加热不燃烧烟弹1处于第二状态(请参见图6)，所述发烟部30部分进入所述第一收容空间41中，部分填充或全部充满所述第一收容空间41。需要说明的是，图6中以所述发烟部30部分进入所述第一收容空间41并部分填充所述第一收容空间41进行示意，并未对所述发烟部30进入所述第一收容空间41的多少进行限定。需要说明的是，所述加热不燃烧烟弹1在制备过程中，也有可能由于加工误差或者加工工序间的运输等原因导致所述发烟部30部分进入所述第一收容空间41，以使得所述加热不燃烧烟弹1处于第二状态。需要说明的是，所述加热不燃烧烟弹1未插入所述烟具时，也可能由于运输或者外力碰撞等原因导致所述发烟部30部分进入所述第一收容空间41，以使得所述加热不燃烧烟弹1处于第二状态。因此，所述第一状态仅表示所述发烟部30处于所述第一收容空间41外部，所述第二状态仅表示所述发烟部30部分进入所述第一收容空间41，可以理解地，所述第一状态及所述第二状态并未对所述加热不燃烧的使用状态进行限定。
需要说明的是，所述第二收容空间42与所述第一收容空间41相同或不同，但所述第二收容空间42具有与所述第一收容空间41相同的作用，即，在另一实施方式中，当所述降温段的朝向与图4中的朝向相反时，所述第二收容空间42相对于所述第一收容空间41靠近所述发烟部30设置，且所述发烟部30可进入所述第二收容空间42。其中，所述第二收容空间 42的体积为30mm 3～35mm 3，优选地为44mm 3～48.5mm 3。
此外，当所述第一收容空间41与所述第二收容空间42相同时，可以使得所述降温部的结构厚度均匀，避免所述降温部在制作时收缩变形，有利于控制所述降温部各部分的尺寸。
请参照图7，图7为图1实施方式提供的加热不燃烧烟弹又一实施方式中沿线A-A的剖面示意图。在本实施方式中，所述第一降温部40还具有一个或多个通气孔43，所述一个或多个通气孔43连通所述第一收容空间41及所述第二收容空间42。
在本实施方式中，所述一个或多个通气孔43连通所述第一收容空间41及所述第二收容空间42，以增加所述降温部的透气性，从而使得所述发烟部30受热产生的气溶胶更好地通过所述降温部。此外，所述收容空间可以起到导流作用，以将所述发烟部30受热产生的气溶胶汇聚至所述一个或多个通气孔43。
请参照图7及图8，图8为图7实施方式提供的加热不燃烧烟弹中第二降温部的降温颗粒的尺寸示意图。在本实施方式中，所述第二降温部60包括多个降温颗粒61，所述通气孔43的内径D1：0.6mm≤D1≤1mm，所述降温颗粒61的等效球直径D2：1mm≤D2≤3.5mm。
在本实施方式中，所述第二降温部60包括多个降温颗粒61，所述降温颗粒61的等效球直径是指所述降温颗粒61的最大长度尺寸。具体地，所述降温颗粒61的等效球直径D2的范围为：1mm≦D2≦3.5mm，使得所述降温颗粒61之间具有适宜的空隙，从而使得所述第二降温部60能够将高温的气溶胶快速降温，且具有较小的抽吸阻力。如若所述降温颗粒61的等效球直径D2过大，则会导致所述降温颗粒61之间的空隙过大，从而降低了所述第二降温部60对气溶胶的降温效果。如若所述降温颗粒61的等效球直径D2过小，则会导致所述降温颗粒61之间的空隙过小，增大了气溶胶通过所述第二降温部60的阻力，从而增加了对气溶胶的抽吸阻力。在一实施方式中(请参见图8中的(a))，所述降温颗粒61为球形，则所述降温颗粒61之间的空隙均匀分布，降低了气溶胶通过所述第二降温部60的阻力，从而减小了对气溶胶的抽吸阻力。在另一实施方式中(请一并参见图8中的(b)、图8中的(c)及图8中的(d))，所述降温颗粒61为不规则形状，即，所述降温颗粒61为各种形状的混合，则降低了所述第二降温部60的加工难度，提高了所述第二降温部60的加工效率，并降低了所述第二降温部60的加工成本。举例而言，所述降温颗粒61可以但不限于图8中的(b)、图8中的(c)或图8中的(d)中的一种或多种形状的混合。需要说明的是，图8中所述降温颗粒61仅作为示意性说明，并未对本申请提供的降温颗粒61的形状进行限定。
此外，所述通气孔43的内径D1需要小于所述降温颗粒61的等效球直径，以防止所述降温颗粒61通过所述通气孔43混入所述发烟部30，从而影响所述加热不燃烧烟弹1的使用。具体地，所述通气孔43的内径D1：0.6mm≤D1≤1mm。
请一并参照图9、图10及图11，图9为图1实施方式提供的加热不燃烧烟弹又一实施方式中沿线A-A的剖面示意图；图10为图9实施方式提供的加热不燃烧烟弹中第一降温部的结构示意图；图11为图10实施方式提供的加热不燃烧烟弹中第一降温部沿线B-B的剖面示意图。在本实施方式中，所述第一降温部40还具有周向均匀设置的多个通气槽44。
在本实施方式中，所述第一降温部40周侧具有均匀分布的多个通气槽44，所述多个通气槽44用于增加所述第一降温部40的透气性，以使得所述发烟部30受热产生的气溶胶更好地通过所述第一降温部40。具体地，所述多个通气槽44与所述管体10的内壁形成通道，以使得所述气溶胶经过所述通道通过。当所述发烟部30包含颗粒状的气溶胶生成基质，即发烟颗粒时，每个所述通气槽44的内径尺寸小于单个发烟颗粒的外径，以防止所述发烟颗粒通过所述通气槽44掉落至所述加热不燃烧烟弹1中的其它结构中，从而影响所述加热不燃烧烟弹 1的使用。具体地，所述通气槽44在预设截面方向上的最大宽度W为：0.8mm≤W≤1.2mm，所述通气槽44的深度H为：0.5mm≤H≤0.6mm。其中，所述预设截面方向垂直于所述第一端11指向所述第二端12的方向。
请再次参照图9、图10及图11，在本实施方式中，所述一个或多个通气孔43在预设截面方向上的截面面积S1与所述多个通气槽44在预设截面方向上的截面面积S2的和与所述第一降温部40在预设截面方向上的截面面积S0的比为：10％≤(S1+S2)/S0≤30％，其中，所述预设截面方向与所述第一端11指向所述第二端12的方向垂直。
在本实施方式中，所述多个通气槽44、所述一个或多个通气孔43及所述第一降温部40在预设截面方向上的截面如图11所示。所述多个通气槽44及所述一个或多个通气孔43需要适合的尺寸以使得所述加热不燃烧烟弹1具有适宜的吸阻。如若所述多个通气槽44及所述一个或多个通气孔43的尺寸过大，则所述加热不燃烧烟弹1的吸阻过小，影响用户吸食体验。如若所述多个通气槽44及所述一个或多个通气孔43的尺寸过小，则所述加热不燃烧烟弹1的吸阻过大，同样会影响用户吸食体验，且所述多个通气槽44及所述一个或多个通气孔43的尺寸过小还会使得所述加热不燃烧烟弹1吸食气溶胶的浓度过低。因此所述多个通气槽44及所述一个或多个通气孔43需要适合的尺寸，具体地，所述多个通气槽44在预设截面方向上的截面面积S1与所述一个或多个通气孔43的在预设截面方向上的截面面积S2的和与所述第一降温部40在预设截面方向上的截面面积S0的比为：10％≤(S1+S2)/S0≤30％。其中，所述预设截面方向与所述第一端11指向第二端12的方向垂直。其中，S1为所有的通气槽44在所述预设截面方向上的截面面积之和，S2为所有的通气孔43在所述预设截面方向上的截面面积之和。
请参照图3及图12，图12为图1实施方式提供的加热不燃烧烟弹中降温部沿线A-A的剖面示意图。在本实施方式中，所述第一降温部40的外径D3大于所述管体10的内径D0，以使得所述第一降温部40与所述管体10形成过盈配合。
在本实施方式中，所述第一降温部40的外径D3大于所述管体10的内径D0，因此所述第一降温部40与所述管体10形成过盈配合，使得所述第一降温部40能够固定于所述管体10，从而使得所述第一降温部40能够设置于所述管体10的预设位置，且保持相对位置不变，以对所述管体10形成支撑。具体地，所述第一降温部40的外径D3为：6.5mm≤D3≤6.8mm，所述管体10的内径D0：6.4mm≤D0≤6.65mm。
请再次参照图12，在本实施方式中，所述第一降温部40的两端具有倒角45，且所述倒角45大小L2：L2＞(D3-D0)/2。
在本实施方式中，所述第一降温部40的两端具有倒角45，且所述倒角45大小L2：L2＞(D1-D0)/2，即所述倒角45在所述第一降温部40的径向方向上的大小为L2，使得所述第一降温部40在所述倒角45处的外径小于所述管体10的内径D0。所述第一降温部40装填进入所述管体10时，所述倒角45可以起到导向辅助装填作用。如若所述第一降温部40无倒角45，或者所述第一降温部40在所述倒角45处的外径大于或等于所述管体10的内径，则在所述第一降温部40装填进入所述管体10时，所述第一降温部40会挤压所述近唇端，从而对所述管体10造成损伤。因此，所述第一降温部40在所述倒角45处的外径小于所述管体10的内径，能够避免在所述第一降温部40装填进入所述管体10时，对所述管体10的近唇端造成损伤。举例而言，所述倒角45在所述第一降温部40的径向方向的长度L2为：0.6mm≤L2≤1mm。所述倒角45的角度不作限定，例如30°、45°、60°、75°等。
此外，所述第一降温部40的长度L4大于所述降温部的外径D3，以便于所述第一降温部 40在装填进入所述管体10之前，对所述第一降温部40的装填方向的识别。如若所述第一降温部40的长度L4小于或等于所述降温部的外径D3，在对所述第一降温部40上料运输时，难以控制所述第一降温部40的长度方向与运输方向一致，或者需要增设方向识别机构来识别所述第一降温部40的方向，降低了所述加热不燃烧烟弹1的制备效率，且容易导致所述第一降温部40的装填出错，具体表现为所述第一降温部40两端朝向所述管体10的内壁装填进入所述管体10。因此，所述第一降温部40的长度L4需要大于所述降温部的外径D3，具体地，L4：8mm≤L4≤10mm，D3：6.5mm≤D3≤6.8mm。
请参照图13、图14及图15，图13为本申请又一实施方式提供的加热不燃烧烟弹的结构示意图；图14为图13实施方式提供的加热不燃烧烟弹沿线C-C线的剖面示意图；图15为图14实施方式提供的加热不燃烧烟弹中I处的局部放大示意图。在本实施方式中，所述加热不燃烧烟弹1包括管体10、封口部20、发烟部30、第一降温部40、过滤部50及第二降温部60。所述管体10具有相背设置的第一端11及第二端12。所述封口部20用于密封所述第一端11。所述发烟部30收容于所述管体10，且所述发烟部30邻近所述第一端11设置。所述第一降温部40收容于所述管体10，且邻近所述发烟部30设置第一降温部40。所述过滤部50收容于所述管体10，且设置于所述第二端12。所述第二降温部60设于所述第一降温部40及所述过滤部50之间。此外，在本实施方式中，所述加热不燃烧烟弹1还包括包装件80，所述包装件80包裹所述管体10，且所述包装件80的两端与所述管体10的两端齐平。
在本实施方式中，所述包装件80用于包裹所述管体10，用于遮蔽所述管体10的外表面上的污垢及斜卷折痕等。具体地，所述包装件80的材料为水松纸，可以但不限于为32～40g/㎡的水松纸。此外，所述包装件80通过平卷的方式包裹所述管体10，以使得所述包装件80的一端端面与所述封口部20背离所述第一端11的面齐平，所述包装件80的另一端端面与所述管体10靠近所述第二端12的面齐平。具体地，所述包装件80的长度L5为：42mm≤L5≤46mm，所述包装件80的外径D5为：7.15mm≤D5≤7.3mm。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
