现有技术中的加热不燃烧气溶胶产生装置，下壳体设置有进气口及与进气口和容纳管道连通的气道，在气溶胶生成基体被加热且用户抽吸气溶胶时，外部空气从进气口进入气道再进入容纳管道，经过气溶胶生成基体内部将气溶胶输送到用户口中。本申请发明人发现，由于该结构的容纳管道与上盖距离近，加热元件的热量容易传到上盖使得上盖温度较高，而上盖一般为用户手持部位，较高的上盖容易烫手，使得用户体验变差。另一方面，气道设置在下壳体，结构复杂，气道路径长，容易出现堵塞现象，降低气溶胶生成基体雾化效率。为了克服上述问题，本申请提供了一种新型的气溶胶产生装置。In the heat-not-burn aerosol generating device in the prior art, the lower casing is provided with an air inlet and an air passage communicating with the air inlet and the accommodating pipe. The air enters the airway from the air inlet and then enters the accommodating duct, and transports the aerosol into the user's mouth through the interior of the aerosol generating matrix. The inventor of the present application found that, due to the short distance between the accommodating pipe and the upper cover of this structure, the heat of the heating element is easily transferred to the upper cover, which makes the temperature of the upper cover higher, and the upper cover is generally the user's hand-held part, and the higher upper cover is easy to burn. , making the user experience worse. On the other hand, the air passage is arranged in the lower casing, the structure is complex, and the air passage path is long, which is prone to blockage and reduces the atomization efficiency of the aerosol-generating matrix. In order to overcome the above problems, the present application provides a novel aerosol generating device.

在一实施例中，如图7和图9所示，底座21朝向收容腔10的端面与接收器1之间形成有环形腔14，环形腔14环绕气溶胶生成基体4设置。该环形腔14具体形成于提取器132朝向底座21的端面上，与第一气道11靠近底座21的一端连通，同时该环形腔14环设于气溶胶生成基体4靠近底座21的一端，且气溶胶生成基体4位于环形腔14的中心位置，第二气道23的进气槽231也与该环形腔14连通，使得气体在该环形腔14处回流后，再次通过进气槽231从气溶胶生成基体4的底部进入。环形腔14的设置可以便于气体从第一气道11内流过，并均匀地流入第二气道23内。环形腔14的外径与底座21靠近提取器132的端面大致相同。环形腔14朝向底座21的一端直径大于位于提取器132的一端，使得环形腔14朝底座21为发散状，更有利于气体的进入。可以理解，该环形腔14也可以是从提取器132朝向底座21的端面形成的一个凹槽，该凹槽的底面具有通孔，该通孔即为接收器1的收容腔10。In one embodiment, as shown in FIGS. 7 and 9 , anannular cavity 14 is formed between the end face of the base 21 facing the receivingcavity 10 and thereceiver 1 , and theannular cavity 14 is arranged around theaerosol generating substrate 4 .

The diameter of the end of theannular cavity 14 toward thebase 21 is larger than that of the end located in theextractor 132 , so that theannular cavity 14 is divergent toward thebase 21 , which is more conducive to the entry of gas. It can be understood that theannular cavity 14 can also be a groove formed from the end face of theextractor 132 toward thebase 21 , the bottom surface of the groove has a through hole, and the through hole is the receivingcavity 10 of thereceiver 1 .

在一实施例中，收容腔10内包括连通的保温段111和降温段112，保温段111相对临近发热组件2设置，降温段112相对临近收容腔10的端口设置；其中，在沿收容腔10的轴向方向上，也就是在沿气溶胶生成基体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。In one embodiment, theaccommodating cavity 10 includes aheat preservation section 111 and acooling section 112 that communicate with each other. In the axial direction, that is, along the direction in which theaerosol generating substrate 4 is inserted into the receivingcavity 10 , the cross-sectional area of theheat preservation section 111 is larger than the cross-sectional area of thecooling section 112 .

具体的，保温段111和降温段112可以构成第一气道11设置在收容腔10内，且保温段111和降温段112为连续的两个气道段，保温段111临近发热组件2设置，具体为临近底座21靠近收容腔10的端面设置，使得底座21可以封盖于保温段111的一端。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可以覆盖至少部分的提取段42。底座21可以用于支撑叶片段41的一端，使得叶片段41与底座21抵接，以固定气溶胶生成基体4。气溶胶生成基体4底部靠近底座21的端面，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。发热件22插设于收容腔10内，并可以进一步插入叶片段41内，以实现对叶片段41的加热，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。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。Specifically, theheat preservation section 111 and thecooling section 112 may constitute thefirst air passage 11 and disposed in the receivingcavity 10, and theheat preservation section 111 and thecooling section 112 are two consecutive air passage sections, and theheat preservation section 111 is disposed adjacent to theheating component 2, Specifically, it is disposed adjacent to the end face of the base 21 close to the receivingcavity 10 , so that the base 21 can be covered on one end of theheat preservation section 111 . The aerosol-generatingsubstrate 4 is inserted into the receivingcavity 10 during use. The aerosol-generatingsubstrate 4 may include aleaf segment 41 and anextraction segment 42 inserted in the receivingcavity 10. Theheat preservation segment 111 may cover at least part of theleaf segment 41 to cool the temperature.Segment 112 may cover at least part ofextraction segment 42 . The base 21 may be used to support one end of theblade segment 41 so that theblade segment 41 abuts with the base 21 to fix the aerosol-generatingsubstrate 4 . The bottom of the aerosol-generatingbase 4 is close to the end face of thebase 21, and theheat preservation section 111 is arranged on the side close to thebase 21, so the heat-preservingsection 111 can keep the aerosol-generatingbase 4 close to thebase 21 for heat preservation, that is, the aerosol-generatingbase 4 of theleaf segments 41 are kept warm. Theheating element 22 is inserted into theaccommodating cavity 10, and can be further inserted into theblade segment 41 to heat theblade segment 41. The inner cavity of theheat preservation segment 111 is at least partially overlapped with theblade segment 41, and theheat preservation segment 111 can be completely Theleaf segments 41 may be covered, or only a part of theleaf segments 41 may be covered. Theheating element 22 may be inserted into a part of theblade segment 41, or may be inserted into the entire length of theblade segment 41 to improve the heating effect, which is not limited in this application.

如图12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. 12 , when theinsulation section 111 completely covers theblade segment 41 , that is, the ratio of the length of theinsulation section 111 to the length of theblade section 41 is greater than or equal to 1.0, the cross-sectional area of theinsulation section 111 is larger than that of thecooling section 112 At this time, the air convection heat transfer coefficient in theinsulation section 111 is relatively small, which can improve the insulation effect of theblade segment 41, prevent the heat from theheating element 22 from dissipating too quickly, and improve the heating efficiency and fogging of the aerosol-generatingsubstrate 4. Improve the user's smoking experience. At the same time, the heat loss of theaerosol generating device 100 can be reduced.

如图13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，具体可以覆盖三分之一或者覆盖二分之一等，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，使得传输到气溶胶生成基体4的提取段42的热量更低，从而使得气溶胶生成基体4的提取段42的温度下降、冷却更快，对于用户来说，气溶胶的入嘴温度更低，可以提高用户的抽吸体验。As shown in FIG. 13 , when theinsulation section 111 covers only a part of theleaf segment 41 , for example, the ratio of the length of theinsulation section 111 covering theblade segment 41 to the length of theblade segment 41 is greater than or equal to 0.25, specifically covering one third or It covers one-half, etc., which is not limited in this application. However, in order to ensure the thermal insulation effect of thethermal insulation section 111 on theblade segment 41, the ratio of the length of thethermal insulation section 111 covering theblade segment 41 to the length of theblade segment 41 should be at least equal to or greater than 0.25. At this time, the heat preservation effect of theheat preservation section 111 on theleaf segment 41 is reduced compared to that of theheat preservation section 111 completely covering theleaf segment 41, so that the heat transferred to theextraction section 42 of the aerosol-generatingsubstrate 4 is lower, thereby making the aerosol-generating substrate The temperature of theextraction section 42 of 4 decreases and the cooling is faster. For the user, the inlet temperature of the aerosol is lower, which can improve the user's suction experience.

降温段112可以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相对临近收容腔10的端口设置，且发热件22并不插入至提取段42，使得提取段42的温度不会升高。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，从而对气溶胶生成基体4的提取段42起到冷却作用，进而降低气溶胶的入嘴温度。Thecooling section 112 can cover at least part of theextraction section 42 of theaerosol generating substrate 4. As mentioned above, thecooling section 112 is relatively close to the port of the receivingcavity 10, and theheating element 22 is not inserted into theextraction section 42, so that theextraction section 42 is not inserted into theextraction section 42. The temperature will not rise. The cross-sectional area of thecooling section 112 is smaller than the cross-sectional area of theheat preservation section 111 , and the air flow here is faster and has a higher convective heat transfer coefficient, thereby playing a role in theextraction section 42 of the aerosol-generatingmatrix 4 . Cooling effect, thereby reducing the inlet temperature of the aerosol.

如图12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可以设置于外壳3的外部，这样更便于用户吸食。同时，由于吸嘴段43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，提升了气溶胶的入嘴口感，并进一步提升用户体验。As shown in FIG. 12 , in other embodiments, the aerosol-generatingsubstrate 4 may further include asuction nozzle section 43, which is the end of theextraction section 42 away from theblade section 41. It can be understood that thesuction nozzle section 43 is for the user Therefore, thesuction nozzle segment 43 can be arranged outside thecasing 3, which is more convenient for the user to suck. At the same time, since thesuction nozzle section 43 is cooled by theextraction section 42, the temperature of the aerosol entering the user's mouth is greatly reduced, the mouthfeel of the aerosol is improved, and the user experience is further improved.

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, thecooling section 112 is a cylindrical cavity, and the radial dimension of thecooling section 112 is larger than the radial dimension of the aerosol-generatingsubstrate 4 , so that the aerosol-generatingsubstrate 4 can pass through thecooling section 112 to the heat-preservingsection 111 . In other embodiments, thecooling section 112 may also be a prismatic cavity, a rectangular cavity, or the like, which is not limited in this application.
