When the aerosol generating device is used, the airflow flows through the cooling section and the heat preservation section in turn to the heating component, so that the heating component atomizes the aerosol generating matrix to generate gas. Sol for the user to ingest. Among them, when the airflow flows through the cooling section, because the cross-sectional area of the cooling section is relatively small, the flow velocity of the airflow is relatively fast and has a high convective heat transfer coefficient, which can cool and cool the aerosol-forming substrate located in the cooling section. , which reduces the inlet temperature of the aerosol and improves the user's suction experience; the airflow enters the insulation section after preheating in the cooling section, and the cross-sectional area of the insulation section is relatively large, the airflow velocity will slow down, and the convective heat transfer in the insulation section The coefficient is also low, so it has a good thermal insulation effect on the aerosol-generating matrix located in the thermal insulation section, which can effectively slow down the heat dissipation of the aerosol-generating matrix in this section, so that the aerosol-generating matrix has a higher atomization ambient temperature , effectively improving the atomization efficiency of the heating element to the aerosol-generating matrix.

在一实施例中，收容腔10的内壁设有第一气道11。第一气道11包括相互连通的保温段111和降温段112，保温段111相对降温段112临近收容腔10底部设置，在收容腔10的轴向方向上，也就是气溶胶生成基体4插入收容腔10的方向上，保温段111的横截面积大于降温段112的横截面积，第一气道11用于供接收器1外部的气体经降温段112和保温段111流入至发热组件2。In one embodiment, the inner wall of the receiving
如图3和图4所示，发热组件2包括底座21和设置于底座21上的发热件22，底座21可以封盖于保温段111的一端，还用于支撑叶片段41，发热件22插设于收容腔10内。发热组件2的一端用于插入叶片段41，具体为发热件22插入叶片段41以实现对叶片段41加热，发热件22可以插入叶片段41的一部分，也可以插入叶片段41的全部长度，提高加热效果，本申请对此不做限定。As shown in FIG. 3 and FIG. 4 , the
具体的，气溶胶生成基体4在使用时插入收容腔10内，气溶胶生成基体4可以包括插设于收容腔10内的叶片段41和提取段42，保温段111可以覆盖至少部分的叶片段41，降温段112用于覆盖至少部分的提取段42。气溶胶生成基体4底部靠近底座21，保温段111设置于靠近底座21的一侧，因此保温段111可以对气溶胶生成基体4靠近底座21的一侧进行保温，即对气溶胶生成基体4的叶片段41进行保温。也就是说，保温段111的内腔与叶片段41是至少部分重合的，保温段111可以完全覆盖叶片段41，也可以只覆盖一部分叶片段41。Specifically, the aerosol-generating
如图5所示，当保温段111完全覆盖叶片段41时，即保温段111的长度与叶片段41的长度之比大于等于1.0，保温段111的横截面积大于降温段112的横截面积，此时保温段111内的空气对流换热系数相对较小，可以提高对叶片段41的保温效果，防止来自发热件22的热量散发过快，提高对气溶胶生成基体4的加热效率和雾化效果，提升用户的抽吸体验。同时，可以降低气溶胶产生装置100的热量损耗。As shown in FIG. 5 , when the
如图6和图7所示，当保温段111只覆盖一部分叶片段41时，例如，保温段111覆盖叶片段41的长度部分与叶片段41的长度之比大于等于0.25，具体可以覆盖如图7所示的三分之一或者覆盖如图6所示的二分之一等，本申请对此不做限定。但是为了保证保温段111对叶片段41的保温效果，保温段111覆盖叶片段41的长度部分与叶片段41的长度之比至少应该大于等于0.25。此时，保温段111对叶片段41的保温效果相对于保温段111完全覆盖叶片段41有所降低，但是降温段112对气溶胶生成基体4的提取段42的降温效果会更明显，对于用户来说，气溶胶的入嘴温度更低。As shown in FIGS. 6 and 7 , when the
在一实施例中，保温段111的长度与叶片段41的长度之比大于等于0.25。需要注意的是，此处为保温段111的长度与叶片段41的长度之间的比值，而不是保温段111覆盖叶片段41的长度与叶片段41的长度之间的比值。如上，由于保温段111可以不完全覆盖叶片段41，因此保温段111的长度与保温段111覆盖叶片段41的长度并不能简单等同，只有当保温段111的长度与叶片段41的长度相等时，保温段111的长度与保温段111覆盖叶片段41的长度才是相等的。In one embodiment, the ratio of the length of the
具体的，如图4至图7所示，由于保温段111需要至少部分覆盖叶片段41，那么保温段111就需要满足一定的长度，以保证对叶片段41的保温效果。叶片段41设置于保温段111内，保温段111需要对叶片段41进行保温时，保温段111的长度至少应该是叶片段41的长度的四分之一，也可以为三分之一、二分之一或者大于等于叶片段41的长度等，本申请对此不做限定。可以理解，保温段111的长度越长，对叶片段41的保温效果越好。在本实施例中，当底座21封盖于保温段111的一端时，气溶胶生成基体4插入收容腔10，气溶胶生成基体4与保温段111靠近的一端与底座21抵接，使得底座21能够对叶片段41形成支撑，即叶片段41远离提取段42的一端与底座21的端面相抵接。优选地，保温段111的长度最长可以为略长于叶片段41的长度，例如，保温段111的长度与叶片段41的长度之比为1.25。如果保温段111的长度过长时，会使得保温段111对气溶胶生成基体4的提取段42进行保温，从而降低降温段112对提取段42的降温效果。Specifically, as shown in FIGS. 4 to 7 , since the
降温段112用于覆盖至少部分气溶胶生成基体4的提取段42，如上所述，降温段112设置于收容腔10远离发热组件2的一侧，且发热件22并不插入至提取段42，不会导致提取段42的温度过高的问题。降温段112的横截面积小于保温段111的横截面积，此时空气在此处的流动速度较快，具有较高的对流换热系数，从而对提取段42起到冷却作用，进而降低气溶胶的入嘴温度。The
如图4所示，在其他实施例中，气溶胶生成基体4还可以包括吸嘴段43，吸嘴段43为提取段42远离叶片段41的一端，可以理解，吸嘴段43是供用户吸食的部分，因此，吸嘴段43可以设置于壳体3的外部，这样更便于用户吸食。同时，由于流至吸嘴段43的气溶胶经过了提取段42的降温，使得进入用户口中的气溶胶温度大大降低，提高了气溶胶的入嘴口感，并进一步提升用户体验。As shown in FIG. 4 , in other embodiments, the aerosol-generating
在一实施例中，降温段112为圆柱腔，降温段112的径向尺寸大于气溶胶生成基体4的径向尺寸，使得气溶胶生成基体4能够穿过降温段112到达保温段111。在其他实施例中，降温段112也可以为棱柱腔、矩形腔等，本申请对此不做限制。In one embodiment, the

优选地，进气槽231的数量为多条，多条进气槽231呈放射状设置于汇聚槽232的周侧。具体的，多条进气槽231以等距离放射状的排列方式均布于汇聚槽232的周围，使得第二气道23能够均匀进气。进气槽231侧壁可以是等宽、不规则或者等距离逐渐向汇聚槽232的方向收窄，如，进气槽231侧壁截面为平行的，或者为波浪形的，或者为发射状等，进气槽231侧壁的形状具体不做限定。在本实施例中，进气槽231从底座21的边缘至汇聚槽232逐渐收窄，形成一个喇叭形状的进气槽231，使得气流从四周向中心能够更好地汇聚。Preferably, the number of the

具体的，第一台阶211和第二台阶212均为环形，第一台阶211的上端面与多个进气槽231连通，使得从接收器1进入的气流在第一台阶211的上端面处进行汇集，然后再进入进气槽231和气溶胶生成基体4，从而使得从外部进入第一气道11的气流能够均匀地流入第二气道23。第一台阶211与第二台阶212之间设置密封件213，使得气流不会进入电源组件5中对电源组件5造成损坏。Specifically, the
