In the fourth embodiment, since both ends of the first housing unit 110 are open, please refer to FIG. 12 and FIG. 13 , the ventilating isolation plugs 300 are all located at the ends of the first housing unit 110 , so it can be The gas permeable isolation plug 300 is directly inserted into the corresponding position, which does not require the gas permeable isolation plug 300 to be inserted into the interior of the housing 100 (eg, between the first end 102 and the second end 103 ), thereby simplifying the assembly process.

In the embodiment of the present application, since the HNB structure 10 is formed with at least two accommodating cavities 101 , the HNB structure 10 is generated by arranging at least two different aerosols in the casing 100 . The substrate 200 provides a prerequisite (of course, only one aerosol-generating substrate 200 can be provided), and due to the arrangement of the air-permeable isolation plug 300, the same or different aerosol-generating substrates in the accommodating cavity 101 are provided. 200 can all be connected to the smoking channel, thereby heating the same or different aerosol-generating substrates 200 in stages (heating only one aerosol-generating substrate 200) or simultaneously heating (heating multiple aerosols at the same time) The production of the base material 200) can enable the user to experience a single taste, multiple tastes, or even a mix of multiple tastes, thereby solving the problems of single taste and single smoking mode existing in traditional heat-not-burn pods, so that the heating does not burn easily. The incendiary cartridge structure 10 has a variety of smoking modes for users to choose.

It needs to be further explained here that the aforementioned "segment heating" and "synchronized heating" can be realized by the heating element. For ease of understanding, let's take the heating element as an example of a cylindrical structure (at this time, the overall structure of the cartridge is also in the form of a cylinder). like structure). "Segmented heating" means that the heating element only heats a part of the casing 100. At this time, the heating element can be designed as a ring-shaped structure that runs through the front and rear, so that it is sleeved on the outer circumference of the casing 100 and corresponds to a certain It can be understood that the aerosol-generating substrate 200 in the receiving cavity 101 will be heated to generate smoke, so as to form a taste corresponding to the aerosol-generating substrate 200. When it is necessary to form other flavors When there is smoke, the position of the heating cylinder can be changed accordingly; "Synchronous heating" means that the heating element heats the entire casing 100 at the same time. At this time, the size of the heating element can be designed to match the casing 100, so as to generate heat After the body is sleeved on the outer periphery of the casing 100, the heating body can heat all parts of the casing 100. At this time, the aerosol-generating substrates 200 in all the accommodating cavities 101 (accommodating cavities) are heated to generate a variety of fumes, thereby Create a mix of flavors. Of course, in addition to this, especially when there are many types of accommodating cavities 101 and aerosol-generating substrates 200 disposed in the accommodating cavities 101 , some of the accommodating cavities 101 can also be heated correspondingly. 101 can be adjacent or spaced apart to form more flavors of smoke and make smoking patterns more diverse.

In order to enable the heating element to perform the aforementioned "segmented heating" or "synchronized heating" on the cartridge structure, the heating element can be designed as follows.

For example, in an embodiment, please refer to FIGS. 1-2 , the side wall of the heating body 20 is provided with a plurality of heating elements 22 , and the plurality of heating elements 22 are respectively electrically connected to the electrodes of the heating element, and the housing 100 has a plurality of receiving In the cavity 101 , a heating element 22 is disposed corresponding to a accommodating cavity 101 , so that the aerosol-generating substrate 200 in the accommodating cavity 101 can be heated in stages.

For another example, in another embodiment, the heating element 20 has a plurality of heating zones, and each heating zone is provided with at least one heating element 22 corresponding to a receiving cavity 101 , and the heating element 22 is arranged on the side wall of the heating element 20 , and The heating elements of each heating zone are respectively electrically connected to the electrodes of the heating element, so that the aerosol-generating substrate 200 in the receiving cavity 101 can be heated in sections.

Of course, simultaneous heating can be achieved by enabling multiple heating elements 22 at the same time.

Further, in some specific embodiments, the heating component may further include a plurality of temperature sensors, the temperature sensors are arranged on the heating body 20, at least one temperature sensor is arranged corresponding to a receiving cavity 101, and the plurality of temperature sensors are respectively used to communicate with the gas. The controller of the sol generating device is connected, and the heating element 22 is a conductive metal material, which is provided on the side wall of the heating body 20 by printing.

Here, by setting a temperature sensor, the temperature in the containing cavity 101 can be monitored to ensure normal operation.

From the above description of the embodiments of the present application, it can be seen that the cartridge structure, the heating assembly and the aerosol generating device in the embodiments of the present application are simpler in structure, which can effectively control the cost and simplify the assembly process. In addition, it can also generate a variety of tastes or taste combinations, and can provide users with a variety of smoking patterns. Especially in some preferred embodiments, for example, when the shell 100 is made of food-grade metal material, the shell 100 has the characteristics of uniform heat conduction and heat resistance, so that the use performance of the pod structure is better. Here On the basis, the cartridge structure in the embodiment of the present application, due to its excellent thermal conductivity, heat can evenly act on the aerosol-generating substrate 200 without producing carbide and smoke burnt smell. Reasonable design can make the cartridge structure have a more compact structure, its body size can be made small enough, and at the same time, it is easier to assemble.
