为了更清楚的说明本发明实施例中的技术方案，下面将对实施例描述中所需要的附图做简单的介绍：
图1是本发明的降温嘴棒的一个具体实施例的结构示意图；

具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施 例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
如图1、图2所示，本发明提出的降温嘴棒，包括中空段1和管簇段2。其中，
中空段1的内部设置有烟气通道11，中空段1的第一端用于连接烟丝段3(如图3、图4所示)，烟丝段3通过加热不燃烧的方式产生烟气。
管簇段2包括两端开口的第一空心管体21，在第一空心管体21的内部设置有多个用于降低烟气温度且两端开口的第二空心管体22，第一空心管体21和多个第二空心管体22分别与烟气通道11连通，相邻的第二空心管体22的侧壁外表面彼此接触，且多个第二空心管体22共同形成的管簇体的外表面与第一空心管体21的内壁接触，当烟气的温度超过第二空心管体22的相变温度或焓变温度时，第二空心管体22的吸热能力增强，从而能够有效吸收烟气中的热量。管簇段2的第一端连接中空段1的第二端，管簇段2的第二端用于供烟气流过而流入使用者嘴中。使用时，高温烟气流经第一空心管体21和第二空心管体22时，第二空心管体22能够有效吸收烟气中的热量，使得通过该降温嘴棒的烟气的高温温度迅速下降至口腔适应温度，从而能够提高抽吸体验。
在一个具体的实施例中，管簇体包括内外多层第二空心管体22，外层的第二空心管体22分别与相邻的内层的第二空心管体22接触，且最外层的第二空心管体22的侧壁外表面分别与第一空心管体21的内壁接触，能够进一步增强管簇体的吸热能力，提高烟气的降温效果。
在一个优选的实施例中，如图2所示，管簇体包括内外两层第二空心管体22，外层的第二空心管体22分别与内层的第二空心管体22接触，且外层的第二空心管体22的侧壁外表面分别与第一空心管体21的内壁接触。再优选的，内层的第二空心管体22的数目为一个。外层的第二空心管体22的数目为多个。再优选的，内层的第二空心管体22设置在管簇体的中部。
在一个具体的实施例中，如图1～4所示，相邻的第二空心管体22呈平行布置且彼此接触。
在一个具体的实施例中，管簇体包括两平行布置且彼此接触的第二空心管体22，两第二空心管体22的侧壁外表面分别与第一空心管体21的内壁接触。
在一个具体的实施例中，管簇体紧箍在第一空心管体21的内部，能够防止管簇体在第一空心管体21的内部发生轴向滑移，稳定性好。管簇体紧箍在第一空心管体21的内部时，使得多个第二空心管体22之间相互挤压，进而使得管簇体具有一定的应力。例如当管簇体包括内外多层第二空心管体22时，内层的第二空心管体22被外层的第二空心管体22挤压，内外多层的第二空心管体22能够形成不易滑落的管簇体。
在一个具体的实施例中，第一空心管体21的内径小于管簇体的外径，使得管簇体嵌入第一空心管体21时受到第一空心管体21内壁的压力，进而使得管簇体紧箍在第一空心管体21的内部而不发生轴向滑移。其中，管簇体的外径等于管簇体横截面的外切圆的直径。
在一个具体的实施例中，第二空心管体22采用热性能材料制成，热性能材料的相变温度或熔点介于35～80摄氏度之间。这样，当烟气温度超过热性能材料的相变温度或熔点，热性能材料迅速发生相变或状态变化，从而能够增强热性能材料的吸热能力，简捷高效。
在一个具体的实施例中，第二空心管体22采用纤维素、多元醇、聚乳酸、聚己内酯和/或聚醚材料制成。
在一个具体的实施例中，第二空心管体22的外径介于0.5～5毫米之间，第二空心管体22的侧壁厚度介于0.01～1毫米之间，吸热效果好。
在一个具体的实施例中，第二空心管体22的长度介于1～20毫米之间，吸热效果好。
在一个具体的实施例中，如图1、图4所示，中空段1包括用于过滤烟气中有害成分的中空纤维管12，烟气通道11设置在中空纤维管12的内部，在中空纤维管12的外表面设置有成型纸。
在一个具体的实施例中，中空纤维管12采用纸质纤维或塑料纤维制成。
在一个具体的实施例中，中空纤维管12设置有内径和外径，中空纤维管12的内径为1～5毫米，中空纤维管的外径为4.5～8毫米。
在一个具体的实施例中，如图1、图3、图4所示，中空段1和管簇段2通过接装纸4包覆成一体以形成降温嘴棒，整体上显示烟草制品的降温嘴棒的外 观。
另一方面，如图3、图4所示，本发明提出的烟草制品，包括上述降温嘴棒和与降温嘴棒连接的烟丝段3。
在一个具体的实施例中，降温嘴棒和烟丝段3之间通过接装纸4连接。
在一个具体的实施例中，烟丝段3包括卷烟纸31和设置在卷烟纸31内部的烟草原料32(如图4所示)。
如图4所示，本发明的烟草制品使用时，烟丝段3通过加热不燃烧的方式产生高温烟气，烟气经中空段1过滤后进入管簇段2中。烟气流经第一空心管体21和第二空心管体22时，第二空心管体22能够有效吸收烟气中的热量，使得通过该降温嘴棒的烟气的高温温度迅速下降至口腔适应温度，从而能够提高抽吸体验。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
