[0001] This application relates to the field of aerosol generation technology, and in particular to aerosol generation apparatus and a control method for the aerosol generation apparatus. Background Technology
[0002] A heated but non-combustible aerosol generating device includes a preheating stage, a holding stage, and an inhalation stage when heating the aerosol-generating product. In the preheating stage, the aerosol-generating product reaches a predetermined temperature within a short time. In the holding stage, the aerosol-generating product is maintained within a predetermined temperature range, thus ensuring stable smoke emission. In the inhalation stage, as the user inhales the smoke, the temperature of the aerosol-generating product decreases. With continuous heating by the aerosol generating device, the temperature of the aerosol-generating product increases, allowing for continuous smoke emission.
[0003] In order to achieve rapid smoke production, the preheating time needs to be shortened. However, in the attempt to shorten the preheating time, the first puff of smoke had problems such as small smoke volume, weak aroma, and inconsistency.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship or movement of the components in a specific orientation (as shown in the accompanying drawings).

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.
[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0030] The aerosol generating device heats the aerosol generating matrix, which then produces aerosols upon heating. When evaluating aerosols generated by this type of heated, non-combustible aerosol generating device, sensory experience is a key and crucial factor, including aspects such as visible smoke volume and inhaled smoke volume, aroma and texture, irritation, mouthfeel, consistency, earthy or burnt taste, etc.
[0031] The heat generated by the heating element of the aerosol generator is transferred to the aerosol generating matrix in a "suitable" manner, effectively and rationally stimulating flavor substances, nicotine, and other components to achieve a good sensory experience. "Suitable" means neither too much nor too little energy. Too much energy may cause problems such as burning, irritation, and scalding smoke temperature; too little may result in unpleasant raw smells, insufficient smoke volume, and ineffective release of flavor substances. Both ultimately lead to a poor sensory experience and negatively impact the consumer experience.
[0032] To achieve a better taste in the first puff or two, the tobacco must be supplied with appropriate energy during the preheating stage to ensure the full release of smoke-producing and aroma compounds. However, during the sensory adjustment of the aerosol generation device, the following phenomenon occurred:
[0033] (1) By using high power (e.g., 20W) for heating during the preheating stage, the aim is to achieve rapid smoke production and faster temperature rise, and to reach the target temperature more quickly, hoping that the heating element will transfer more heat to the tobacco during the preheating stage. However, it was found that the irritation was enhanced and the consistency was poor;
[0034] (2) Using the same heating element and a specific type of cigarette, the battery directly supplies power to the heating element, meaning the battery charge is directly applied to both ends of the heating element to ensure that the heating element heats up to the target temperature as quickly as possible. During the process of adjusting the temperature field distribution, specifications, size, device structure, and relative position of the cigarette and the heating element, it was found that the first two puffs of the cigarette had a poor sensory experience, such as small smoke volume, weak aroma, and inconsistent performance, making it impossible to achieve excellent sensory effects.
[0035] Based on the above debugging and testing, it was unexpectedly discovered that during the preheating stage, the higher the power used by the heating unit to raise the temperature, the faster the temperature rises to its highest point, making it easier to form localized hot zones and causing the tobacco to stick together. The sticky tobacco becomes harder, exhibiting a phenomenon similar to soil compaction. Testing revealed that the thermal conductivity of the sticky tobacco remained within the range of 0.05 W / mK to 0.2 W / mK. In other words, the sticky tobacco surrounding the heating unit acts as excellent insulation, preventing the heating element from transferring heat properly. This means that tobacco at a certain distance from the heating element cannot absorb enough energy, and the tobacco closest to the heating element is over-baked, resulting in a burnt or pungent taste.
[0036] Based on this, embodiments of this application provide a control method for an aerosol generating device. The aerosol generating device is used to heat an aerosol generating product to generate aerosols. In a theoretical state, during the preheating stage, the aerosol generating product uses a preset heating power of P0 and a preset heating time of t0. It should be noted that "preset heating power P0" can be understood as the preheating power commonly used in related technologies, such as the theoretical preheating power determined based on factors such as battery capacity, the structure of the heating components (e.g., center heating, circumferential heating, or bottom heating), the heating method (e.g., resistance heating, microwave heating, air heating, or electromagnetic heating), the length of the tobacco segment inside the aerosol generating product, and the preheating time; "preset heating time t0" can be understood as the length of time used to preheat the aerosol generating device with the preset heating power P0.
[0037] Control methods for aerosol generation devices include:
[0038] In the preheating stage of the aerosol-generated product, the aerosol-generated product is heated using a first power P1, with a preset heating time of t0, where P1 is less than P0.
[0039] This application reduces the power during the preheating stage from P0 to P1. By using a power value P1 lower than the theoretical heating power, the probability of localized hot spots in the aerosol-generated product near the heating unit can be reduced, effectively preventing tobacco from sticking together. In this way, the heat generated by the heating unit can be smoothly diffused from the area near the heating unit to the area further away, allowing the aerosol-generated product to heat up quickly and evenly. This shortens the smoke generation time, enriches the smoke flavor, and improves smoke consistency.
[0040] Aerosol generating articles may include a mouthpiece, a connecting section, and a tobacco segment capable of generating aerosols. The connecting section, located between the mouthpiece and the tobacco segment, guides the aerosol to the mouthpiece. The mouthpiece is for a user to hold in their mouth, allowing the user to inhale the aerosol by sucking on the mouthpiece. The tobacco segment in the aerosol generating article may contain an aerosol generating matrix.
[0041] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. An aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, an aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, an aerosol-generating matrix may include non-tobacco materials. An aerosol-generating matrix may also include aerosol-forming agents. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.
[0042] As needed, the aerosol generating matrix may contain additional tobacco or non-tobacco volatile aroma compounds released when the aerosol generating matrix is heated. The aerosol generating matrix may also contain microcapsules, which may contain additional tobacco or non-tobacco volatile aroma compounds, and such microcapsules may melt during heating of the solid aerosol generating matrix.
[0043] The aerosol-generating article can be generally a rod-shaped structure extending longitudinally. The mouthpiece can be positioned adjacent to the proximal end of the aerosol-generating article. The tobacco segment can be positioned adjacent to the distal end of the aerosol-generating article.
[0044] In one embodiment of this application, the value of P1 ranges from 4W to 14W. In one embodiment of this application, the value of P1 ranges from 5W to 10W. In one embodiment of this application, the value of P1 is 4W, 5W, 6W, 7W, 9.5W, 10W, or 14W.
[0045] In one embodiment of this application, the preset heating time t0 ranges from 10 to 30 seconds. In another embodiment of this application, the preset heating time t0 ranges from 20 to 30 seconds. In yet another embodiment of this application, the preset heating time t0 is 10 seconds, 15 seconds, 18 seconds, 20 seconds, 22 seconds, 25 seconds, 28 seconds, or 30 seconds.
[0046] In one embodiment of this application, the aerosol generating article has a first position close to a heat source and a second position far from the heat source. The control method further includes monitoring the temperature of the first and second positions. In related technologies, the temperature of the aerosol generating article is monitored along its axial direction. While this can detect temperature changes, it does not analyze and compare the details of the temperature rise, especially the radial temperature transfer rate from the inner to the outer side of the aerosol generating article. This is one of the reasons why the technical problem of this application is difficult to discover.
[0047] Furthermore, in pursuing rapid heating, technicians often consider high-power heating to quickly raise the temperature of the aerosol-generated product to the predetermined target. However, they fail to realize that rapid heating causes instantaneous localized overheating of the tobacco, leading to the formation of tobacco residue near the heating unit. This residue adheres to each other, reducing the porosity and hindering heat conduction. The adhered residue acts as excellent insulation, making it difficult for heat near the heating unit to transfer to areas further away. Consequently, with higher heating power, the temperature rise rate slows down, the amount of smoke decreases, the aroma deteriorates, and a burnt or pungent taste may develop.
[0048] Therefore, by monitoring the temperatures at the first and second positions, and considering the distance between these positions relative to the heating unit, the temperature rise pattern of the aerosol-generated product can be clearly understood. This provides data support for relevant technicians to identify technical problems related to the difficulty in increasing the temperature rise rate with high-power heating. Consequently, the heating power of the heating element can be adjusted based on the temperature changes at the first and second positions and the temperature rise rate, thereby achieving uniform heating and precise temperature control.
[0049] In one embodiment of this application, in the case of central heating, such as Figure 2 As shown, the first position is located at a predetermined distance from the outer peripheral wall of the aerosol generating article, and the second position is located on the outer peripheral wall of the aerosol generating article. It should be noted that in related technologies, the centrally heated aerosol generating device can employ a heating needle structure. The heating needle is inserted into the aerosol generating article, and the heating needle generates heat, which heats the aerosol generating article. For example, the heating needle is inserted into the interior of the aerosol generating article along its central axis. The first position can be located near the heating needle, and the first and second positions are spaced apart along the radial direction of the aerosol generating article, with a distance of 2.2 mm between them.
[0050] In one embodiment of this application, in the case of circumferential heating, the first position is located on the outer peripheral wall of the aerosol generating article, and the second position is located at a predetermined distance from the outer peripheral wall of the aerosol generating article.
[0051] It should be noted that in the related technology, the circumferentially heated aerosol generating device can adopt a heating tube structure. The aerosol generating product is inserted into the heating tube, and the heat generated by the heating tube is transferred from the outer periphery of the aerosol generating product to the inner side of the aerosol generating product. The first position can be set at a position close to the heating tube. For example, the first position can be set on the outer peripheral wall of the aerosol generating product. The first position and the second position are distributed at intervals along the radial direction of the aerosol generating product, and the distance between the first position and the second position is 2.2 mm.
[0052] By monitoring the temperatures at the first and second locations, temperature information at different locations on the aerosol-generated product can be accurately captured, thereby obtaining information such as the heat transfer rate of the aerosol-generated product and enabling precise temperature control.
[0053] In one embodiment of this application, the control method for the aerosol generating device further includes: after the preheating stage, entering a heat preservation stage, wherein the heating power is P2, and P2 is less than P1. In one embodiment of this application, the preheating power is 2W-4W. In one embodiment of this application, the preheating power is 2W, 2.5W, 3W, 3.5W, or 4W.
[0054] One embodiment of this application provides an aerosol generating apparatus. The aerosol generating apparatus employs the control method described above, and includes a heating component for heating the aerosol-generated product.
[0055] In one embodiment of this application, the heating component is a center-pin heating component or a circumferential heating component. When the heating component is a center-pin heating component, the outer peripheral wall to which the aerosol is generated is the second position; when the heating component is a circumferential heating component, the outer peripheral wall of the aerosol-generated article is the first position.
[0056] The control method for an aerosol generating apparatus according to embodiments of this application is described in detail below using specific examples. It is worth understanding that the following description is merely illustrative and not intended to limit the scope of this application.
[0057] An aerosol generating device employing a central needle heating assembly includes an aerosol generating product with a cylindrical structure. The product comprises a mouthpiece, a connecting section, and a tobacco segment capable of generating aerosols. The connecting section, located between the mouthpiece and the tobacco segment, guides the aerosol to the mouthpiece. The mouthpiece is for the user to hold in their mouth, allowing them to inhale the aerosol by sucking on it. The tobacco segment within the aerosol generating product may contain an aerosol generating matrix.
[0058] At the tobacco segment, the second position is set at the outer peripheral wall of the tobacco segment, and the position 2.2 mm away from the outer peripheral wall is set as the first position.
[0059] Example 1
[0060] Theoretically, during the preheating stage, the aerosol-generating product uses a preset heating power of 20W, i.e., P0 = 20W. Using the theoretical heating power of 20W for the aerosol-generating product as a comparative example, and a preheating stage heating power of 14W as Example 1, the relationship between temperature T10 and time at the first position was measured in both the comparative example and Example 1. Figure 3 The relationship between temperature T20 and time at the second location in the comparative example and Example 1 was detected respectively. Figure 4 .
[0061] Depend on Figure 3 It can be seen that, compared with the comparative example, the temperature at the first position is higher in Example 1 after preheating for 20s-30s.
[0062] Depend on Figure 4 It can be seen that, in Example 1, the temperature at the second position is approximately the same as that in the comparative example after preheating for 20-30 seconds.
[0063] It should be noted that in the comparative example, a heating power of P0 = 20W was used. During the preheating stage, the center needle generated a large amount of heat. The tobacco near the center needle became sticky due to the excessive temperature and clumped around the center needle. The tobacco in this clumped area was significantly harder than the tobacco in other parts of the body. The sticky tobacco formed an insulating structure around the center needle, making it difficult for heat to transfer to the outer periphery, thus preventing the outer tobacco from receiving sufficient heat. Furthermore, the sticky tobacco, due to over-roasting, developed a burnt or pungent taste.
[0064] In Example 1, due to the use of a relatively low heating power P1 = 14W, the center pin generates relatively little heat during the preheating stage. This allows for moderate roasting of the tobacco, keeping it relatively loose and preventing it from sticking together. Heat near the center pin can then be quickly transferred to the periphery, meaning heat is rapidly transferred from the first position to the second position. This ensures uniform roasting of the tobacco both near and away from the center pin, shortening smoke generation time, increasing smoke volume, and fully developing aroma, resulting in a richer flavor, better smoke consistency, and a superior smoking experience for the user.
[0065] Example 2
[0066] Theoretically, during the preheating stage, the aerosol-generated product uses a preset heating power of 20W, i.e., P0 = 20W. Using the theoretical heating power of 20W for the aerosol-generated product as a comparative example, and a preheating stage heating power of 9.5W as Example 2, the product is used for comparison.
[0067] The temperature at the first position is T10, and the temperature at the second position is T20. The relationship between the temperature at the first and second positions and time under the conditions of power of 9.5W and 20W is shown in Table 1.
[0068] Table 1. Relationship between T10 and T20 and time.
[0069]
[0070] As shown in Table 1, during the preheating stage, when preheating for 20 seconds:
[0071] In the comparative example, the heating power is 20W, the temperature T10 at the first position is 174.65℃, and the temperature T20 at the second position is 73.4℃.
[0072] In Example 2, the heating power is 9.5W, the temperature T10 at the first position is 195.84℃, and the temperature T20 at the second position is 71.1℃.
[0073] Clearly, at the first position, the temperature is significantly higher when heating with 9.5W than when heating with 20W. However, at the second position, the temperature is almost the same when heating with 9.5W as when heating with 20W.
[0074] Similarly, during preheating at 30s, 40s, 80s, and 150s, at the first position, the temperature was significantly higher when heating with 9.5W than when heating with 20W. However, at the second position, the temperature was almost the same when heating with 9.5W as when heating with 20W.
[0075] It should be noted that in the comparative example with a heating power of 20W, due to the higher heating power, the center needle generated a large amount of heat. The tobacco near the center needle was over-baked, causing it to stick together and clump around the center needle. This clump of tobacco was significantly harder than the tobacco in other areas. The sticky tobacco formed an insulating structure around the center needle, making it difficult for heat to transfer to the outer edges, thus preventing the outer tobacco from receiving sufficient heat. The over-baked, sticky tobacco also developed a burnt or pungent taste.
[0076] In Example 2, due to the use of a lower heating power P1 = 9.5W, the center pin generates relatively less heat during the preheating stage. This allows for moderate roasting of the tobacco, keeping it relatively loose and preventing it from sticking together. Heat near the center pin can then be quickly transferred to the periphery, meaning heat is rapidly transferred from the first position to the second position. This ensures uniform roasting of the tobacco both near and away from the center pin, shortening smoke generation time, increasing smoke volume, and fully developing aroma, resulting in a richer flavor, better smoke consistency, and a superior smoking experience for the user.
[0077] In summary, aerosols generated closer to the heat source heat up rapidly, resulting in concentrated heat. Overheated tobacco forms tobacco residue, which reduces its porosity, making heat conduction difficult and acting as a good insulating material. This makes the aerosol-generating matrix at the first location prone to poor heat transfer to the surrounding area. Therefore, when the heating power is high, the temperature rise rate slows down, the amount of smoke decreases, and the aroma deteriorates. Furthermore, the first location is prone to over-baking, producing a burnt or pungent taste. However, when the heating power is reduced during the preheating stage, the aerosol-generating matrix does not stick together, and the temperature can be conducted rapidly. The aerosol-generated product at the first location closest to the heat source experiences a rapid temperature rise and uniform heating. As a result, the aerosol-generated product can produce a large amount of smoke, and the aroma can be evenly activated, enhancing the aroma and flavor.
[0078] The control method for an aerosol generating apparatus according to embodiments of this application will be described below from a sensory perspective. It is worth understanding that the following description is merely illustrative and not a specific limitation of this application.
[0079] When the heating power during the preheating stage is 20W, the sensory dimensions of the aerosol-generated products are tested. The resulting aerosol smoke volume is small, the aroma is weak, the irritation is strong, and the consistency is poor.
[0080] The preheating power of 10W, 7W, 6W, 5W and 4W were respectively used as Examples 3, 4, 5, 6 and 7. The same aerosol generating device and the same aerosol generating product were used as comparative examples. The sensory dimensions of the aerosol generating products under different power were tested and obtained in Table 2.
[0081] Table 2 Sensory dimensions of aerosol-generated products at different power levels
[0082]
[0083] As shown in Table 2, reducing the heating power during the preheating stage can result in a greater amount of smoke, a stronger aroma, better consistency, and a better inhalation experience for users of aerosol-generated products.
[0084] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
