Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an aerosol generating device and an aerosol generating system. Background Technology

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. Under the electrical drive of the power supply component, the atomizer atomizes the aerosol generating matrix and / or aerosol generating product to form an aerosol for user use. In related technologies, the aerosol generating method of a single aerosol generating device is relatively limited, failing to provide users with a novel inhalation experience. Therefore, improving the limited aerosol generating method of aerosol generating devices has become an important research direction in this field. Summary of the Invention

[0003] In view of this, the embodiments of this application aim to provide an aerosol generating device and an aerosol generating system, which is beneficial to improving the problem of the relatively limited methods of aerosol generation.

[0007] A power supply assembly for selectively connecting electrically to the first atomizer and / or the second atomizer.

[0008] In some embodiments, the first atomizing element includes a plurality of heating elements arranged along a first direction, and the power supply component is used to selectively provide electrical energy to each of the heating elements, wherein the first direction is the extension direction of the aerosol generating article.

[0010] In some embodiments, the heating element closest to the lip end of the aerosol generating article among the plurality of heating elements has the smallest dimension along the first direction.

[0011] In some embodiments, the plurality of heating elements includes a first heating element, a second heating element, and a third heating element, which are arranged sequentially along the direction from the proximal lip end to the distal lip end of the aerosol generating article.

[0012] In some embodiments, the dimension of the first heating element along the first direction is less than or equal to the dimension of the second heating element along the first direction, and the dimension of the second heating element along the first direction is less than or equal to the dimension of the third heating element along the first direction.

[0013] In some embodiments, the sum of the dimensions of the first heating element along the first direction and the dimensions of the second heating element along the first direction is greater than or equal to the dimensions of the third heating element along the first direction.

[0014] In some embodiments, the aerosol generating article includes an aerosol generating medium section, and the first atomizing element is used to atomize the aerosol generating medium section;

[0015] In the first direction, the third heating element cannot completely cover the aerosol generating medium section; and / or,

[0016] The dimension of the third heating element along the first direction is smaller than the dimension of the aerosol generating medium segment along the first direction.

[0017] In some embodiments, the aerosol generating article includes an aerosol generating medium segment, and the distance between the proximal lip end of the heating element and the proximal lip end of the aerosol generating article is less than or equal to the distance between the proximal lip end of the aerosol generating medium segment and the proximal lip end of the aerosol generating article.

[0018] In some embodiments, the aerosol generating device includes a first operating state, in which the power supply component is electrically connected to the first heating element and the second heating element; and / or,

[0019] The aerosol generating device includes a second operating state, in which the power supply component is electrically connected to the second heating element; and / or,

[0020] The aerosol generating device includes a third operating state, in which the power supply component is electrically connected to the third heating element.

[0021] In some embodiments, the dimension of the first heating element along the first direction is in the range of 2.8 mm to 4.5 mm; and / or,

[0022] The second heating element has a dimension in the first direction ranging from 4.5 mm to 7.5 mm; and / or,

[0023] The dimensions of the third heating element along the first direction are in the range of 6mm to 8mm.

[0024] In some embodiments, the number of heating elements is n, and the first atomizing element further includes a common lead and n sub-leads. The common lead is electrically connected to all the heating elements, and the n sub-leads are electrically connected to the n heating elements one by one.

[0025] In some embodiments, the first atomizer and the second atomizer are arranged along the first direction and along the aerosol flow direction, with the first atomizer located downstream of the second atomizer.

[0026] In some embodiments, the first atomizing element includes a heating element, the heating element having the receiving chamber inside, and the plurality of heating elements disposed on the outer or inner wall of the receiving chamber.

[0027] In some embodiments, the second atomizer includes an outlet channel, through which the aerosol generated by the second atomizing element atomizing the aerosol generating matrix is ​​discharged; the aerosol generating device further includes a connector having a connecting channel, through which the outlet channel is connected to the receiving chamber.

The first atomizing element of the first atomizer is used to atomize the aerosol generating product, and the second atomizing element of the second atomizer is used to atomize the aerosol generating matrix. In other words, the aerosol generating product and the aerosol generating matrix can be atomized by the first and second atomizers respectively to generate aerosols. This helps to address the problem of the relatively limited aerosol generation methods in aerosol generating devices, providing users with a new and improved user experience. Furthermore, the first atomizer or the second atomizer can operate independently to generate aerosols, which enhances the versatility and convenience of the aerosol generating device. Furthermore, the first atomizing element can be configured to include multiple heating elements. Depending on the application scenario, only one heating element or multiple heating elements can be selected to work simultaneously to adapt to the atomization of different types of aerosol generating products. In addition, in the embodiment where only one heating element works, heating elements at different positions can be selected to work to further adapt to the atomization of different types of aerosol generating products.

[0039] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0040] In the description of the embodiments of this application, it should be noted that the terms "proximal lip end," "distal lip end," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] One aspect of this application provides an aerosol generation system 1000. Please refer to [link to relevant documentation]. Figures 1 to 4 The aerosol generation system 1000 includes an aerosol generation article 200 and an aerosol generation device 100 provided in any embodiment of this application, wherein at least a portion of the aerosol generation article 200 is contained within a containment chamber 121.

[0042] One aspect of this application provides an aerosol generating apparatus 100. Please refer to [link to relevant documentation]. Figures 1 to 6 The aerosol generating device 100 includes a first atomizer 10, a second atomizer 20, and a power supply assembly 70. The first atomizer 10 includes a first atomizing element 11 and a receiving chamber 121. The receiving chamber 121 is used to contain the aerosol generating product 200, and the first atomizing element 11 is used to atomize the aerosol generating product 200. The second atomizer 20 includes a second atomizing element 21 and a liquid storage chamber 22. The liquid storage chamber 22 is used to store the aerosol generating matrix. The second atomizing element 21 is in liquid communication with the liquid storage chamber 22 and is used to atomize the aerosol generating matrix. The power supply assembly 70 is used to selectively connect electrically to the first atomizer 10 and / or the second atomizer 20.

[0043] The power supply assembly 70 being used to selectively connect to the first atomizer 10 and / or the second atomizer 20 means that the power supply assembly 70 can be simultaneously connected to the first atomizer 10 and the second atomizer 20; the power supply assembly 70 can be electrically connected to the first atomizer 10 and disconnected from the second atomizer 20; or the power supply assembly 70 can be electrically connected to the second atomizer 20 and disconnected from the first atomizer 10.

[0044] When the power supply assembly 70 is electrically connected to both the first atomizer 10 and the second atomizer 20, the first atomizer 10 and the second atomizer 20 work simultaneously. That is, both the first atomizer 10 and the second atomizer 20 can generate aerosols. The aerosols generated by the first atomizer 10 and the second atomizer 20 are mixed and then used by the user, bringing a new user experience.

[0045] When the power supply assembly 70 is electrically connected to the first atomizer 10 and disconnected from the second atomizer 20, the first atomizer 10 is in a working state and the second atomizer 20 is in a non-working state. That is to say, the first atomizer 10 can generate aerosol for the user, while the second atomizer 20 does not generate aerosol.

[0046] When the power supply assembly 70 is electrically connected to the second atomizer 20 and disconnected from the first atomizer 10, the second atomizer 20 is in a working state and the first atomizer 10 is in a non-working state. That is to say, the second atomizer 20 can generate aerosol for the user, while the first atomizer 10 does not generate aerosol.

[0047] In other words, users can selectively connect the power supply component 70 to the first atomizer 10 and / or the second atomizer 20 according to their needs, thereby adjusting the way the aerosol generating device 100 generates aerosols. This helps to improve the problem that the aerosol generating device 100 generates aerosols in a relatively singular way.

[0048] Furthermore, when the aerosol generating product 200 is used up, the user can also atomize the aerosol generating matrix through the second atomizing element 21 to generate aerosol; when the aerosol generating matrix is ​​used up, the user can also atomize the aerosol generating product 200 through the first atomizing element 11 to generate aerosol, which improves the ease of use and reliability of the aerosol generating device 100 and further enhances the user experience.

[0049] In other words, the aerosol generating device 100 can activate only the first atomizer 10 without activating the second atomizer 20. In this case, the first atomizing element 11 can operate and atomize the aerosol generating product 200 to generate aerosols. Alternatively, the aerosol generating device 100 can activate only the second atomizer 20 without activating the first atomizer 10. In this case, the second atomizing element 21 can directly atomize the aerosol generating matrix to generate aerosols. Of course, the aerosol generating device 100 can also activate both the first atomizer 10 and the second atomizer 20.

[0050] For example, the aerosol generating device 100 also includes a mixing mode. When in use, the controller of the aerosol generating device 100 determines whether the status of the second atomizer 20 is normal. If it is normal, the first atomizer 10 and the second atomizer 20 are started simultaneously to use the mixing mode. If the controller determines that the second atomizer 20 is missing or cannot work properly (e.g., there is no aerosol generating matrix in the liquid storage chamber 22), the first atomizer 10 is started and the second atomizer 20 is turned off.

[0051] In some embodiments, the first atomizer 10 and / or the second atomizer 20 exist independently of the power supply assembly 70, and the first atomizer 10 and / or the second atomizer 20 are detachably connected to the power supply assembly 70. However, in some embodiments, the first atomizer 10 and / or the second atomizer 20 are encapsulated within the same housing 23 as the power supply assembly 70, and are relatively non-detachable.

[0052] The power supply component 70 is mainly used to supply power to the first atomizer 10 and / or the second atomizer 20, and to control the opening and closing of the entire aerosol generating device 100. The first atomizer 10 and / or the second atomizer 20 are mainly used to contain the aerosol generating product 200 and / or the aerosol generating matrix, and to atomize the aerosol generating product 200 and / or the aerosol generating matrix after power is applied. The aerosol generating product 200 and / or the aerosol generating matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.

[0053] In some embodiments, the first atomizer 10, the second atomizer 20, and the power supply assembly 70 can be mechanically and electrically connected together. Further, the first atomizer 10, the second atomizer 20, and the power supply assembly 70 can be detachably connected by means of magnetic connection, threaded connection, snap-fit ​​connection, or other similar methods. Each of the first atomizer 10, the second atomizer 20, and the power supply assembly 70 can be individually replaced or upgraded, reducing replacement costs and saving user expenses. Of course, in other embodiments, the first atomizer 10, the second atomizer 20, and the power supply assembly 70 can also be non-detachably connected together.

[0054] It should be noted that the specific type of aerosol generating device 100 provided in this application embodiment is not limited. For example, the aerosol generating device 100 can be a medical nebulizer, an air humidifier, or an electronic cigarette or other nebulizer.

[0055] For example, please refer to Figures 5 to 6 The second atomizer 20 also includes an exhaust channel 26, which is used to discharge the aerosol generated by the atomizing aerosol generation matrix of the second atomizing element 21.

[0056] Here, the aerosol generating matrix is ​​in a liquid state. The second atomizing element 21 is in liquid communication with the liquid storage chamber 22. The aerosol generating matrix in the liquid storage chamber 22 can flow to the second atomizing element 21. The second atomizing element 21 atomizes the aerosol generating matrix and generates aerosol.

[0057] Here, the aerosol generating product 200 is in a solid state, meaning that the aerosol generating product 200 is different from the aerosol generating matrix, which helps to improve the richness of aerosols.

[0058] Furthermore, the first atomizing element 11 of the first atomizer 10 is used to atomize the aerosol generating product 200, and the second atomizing element 21 of the second atomizer 20 is used to atomize the aerosol generating matrix. By designing the composition of the aerosol generating product 200 and the aerosol generating matrix, differentiation of the aerosols generated by the aerosol generating product 200 and the aerosol generating matrix can be achieved, thereby enhancing the richness of the aerosols. In addition, by controlling the atomization amount of the first atomizer 10 and the second atomizer 20, it is further beneficial to enhance the diversification of aerosols.

[0059] This application provides an aerosol generating device 100, which includes a first atomizer 10 and a second atomizer 20. The first atomizing element 11 of the first atomizer 10 is used to atomize the aerosol generating product 200, and the second atomizing element 21 of the second atomizer 20 is used to atomize the aerosol generating matrix. In other words, the aerosol generating product 200 and the aerosol generating matrix can be atomized by the first atomizer 10 and the second atomizer 20 respectively to generate aerosols. This improves the problem of the relatively singular aerosol generation method of the aerosol generating device 100, providing users with a new user experience and thus enhancing the user experience. Furthermore, the first atomizer 10 or the second atomizer 20 can also operate independently to generate aerosols, which improves the versatility and convenience of the aerosol generating device 100.

[0060] For example, the aerosol generating article 200 includes an aerosol generating medium section 210 for generating aerosols.

[0061] For example, the aerosol generating medium section 210 is a particulate aggregate, also known as a powder aggregate, which is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing smoke-generating agents, tobacco, and other components. The aerosol generating medium section 210 has a one-piece structure, for example, it can be formed into a one-piece structure by extrusion, injection molding, or die casting processes. Among them, extrusion molding refers to a processing method in which a mixture of raw materials is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passed through the die at the extruder outlet to form products or semi-finished products of various cross sections. The medium structure formed by extrusion molding is strip-shaped. In this way, the aerosol generating medium section 210 remains a one-piece medium after being heated and drawn in or after the heating stops, and it is not easy to disintegrate and fall off. This solves the problems of thin sheet, filament, or loose particulate aerosol generating medium sections 210 in the prior art, such as loose sheet, shedding of filamentous components and particulate components, difficulty in cleaning, and uneven composition.

[0062] Of course, the smoke-generating material of the aerosol generating medium section 210 can be granular, tobacco-like, or sheet-like, and can be formed into aerosol generating product 200 through integrated filling, rolling, or agglomeration molding.

[0063] For example, please refer to Figures 2 to 3 The aerosol generating article 200 includes a functional segment 220, which is arranged along a first direction with the aerosol generating medium segment 210, and the functional segment 220 is disposed near the lip end of the aerosol generating medium segment 210.

[0064] The proximal end refers to the end of the aerosol generating product 200 that is closer to the user when the user is using it, while the distal end refers to the end of the aerosol generating product 200 that is farther away from the user when the user is using it.

[0065] For example, functional segment 220 includes a filter segment that can filter out large particulate components and unwanted impurities in the flowing aerosol.

[0066] For example, functional segment 220 includes a cooling segment that can cool the flowing aerosol.

[0067] For example, functional segment 220 includes a support segment that has a support function.

[0068] It is understandable that since the aerosol flows through the support section or filter section, the support section or filter section can also play a certain role in cooling the aerosol.

[0069] In some embodiments, the aerosol generated in the heated aerosol generating medium section 210 can first flow through a cooling section for cooling, and then the cooled aerosol flows through a filtration section, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated in the heated aerosol generating medium section 210 is cooled and filtered sequentially through the cooling section and the filtration section before being drawn in by the user.

[0070] In other embodiments, the aerosol generated by the heated aerosol generating medium section 210 first flows through a filtration section for filtration. The filtration section can filter out large particles and unwanted impurities in the aerosol. After filtration, the aerosol then flows through a cooling section for cooling. That is, the aerosol generated by the heated aerosol generating medium section 210 is filtered and cooled sequentially through the filtration section and the cooling section before being drawn in by the user.

[0071] For example, please refer to Figure 3 The aerosol generating article 200 also includes a front plug section 230, which is arranged along the first direction with the aerosol generating medium section 210, and the front plug section 230 is disposed at the distal lip end of the aerosol generating medium section 210.

[0072] The front plug section 230 is disposed at one end of the aerosol generating medium section 210 and located at the distal lip end of the aerosol generating product 200. On the one hand, during use, the front plug section 230 can effectively reduce the probability of the aerosol generating medium section 210 falling out of the outer packaging layer; on the other hand, it can also effectively prevent the aerosol from condensing and flowing downward and remaining in the receiving chamber 121 of the aerosol generating device 100, thereby causing internal contamination of the receiving chamber 121 and making it difficult to clean, and also preventing the problem of cross-contamination of flavors when sucking in different flavored aerosol generating products 200.

[0073] It should be noted that there are multiple possible relative positions between the first atomizer 10 and the second atomizer 20.

[0074] In some embodiments, please refer to Figure 2 The first atomizer 10 and the second atomizer 20 are arranged along the first direction and along the aerosol flow direction, the first atomizer 10 is located downstream of the second atomizer 20.

[0075] For example, the aerosol generating device 100 has an air inlet channel at the bottom, through which external air can enter the second atomizer 20 and then carry the aerosol generated by the atomizing aerosol generating matrix of the second atomizer 20 into the first atomizer 10.

[0076] Here, the aerosol generated by the aerosol generating matrix atomized by the second atomizer 20 can enter the first atomizer 10 and mix with the aerosol generated by the aerosol generating product 200 atomized by the first atomizing element 11 to form a "new" aerosol for user use. Alternatively, the aerosol generated by the aerosol generating matrix atomized by the second atomizer 20 can enter the aerosol generating product 200 of the first atomizer 10, carrying out the effective components within the aerosol generating product 200 to form a "new" aerosol for user use. It should be noted that the "new" aerosol mentioned above refers to an aerosol that is different from the aerosol generated by the aerosol generating matrix of the second atomizer 20 and the aerosol generated by the aerosol generating product 200 of the first atomizing element 11. Instead, it is formed by mixing the aerosol generated by the aerosol generating matrix of the second atomizer 20 with the aerosol generated by the aerosol generating product 200 of the first atomizing element 11, or by mixing the aerosol generated by the aerosol generating matrix of the second atomizer 20 with the effective components in the aerosol generating product 200.

[0077] In this embodiment, by placing the first atomizer 10 downstream of the second atomizer 20 along the aerosol flow direction, it is convenient to set up the air passage of the aerosol generating device 100, thereby simplifying the structure and improving the structural compactness of the aerosol generating device 100.

[0078] In some embodiments, please refer to Figures 2 to 4 The first atomizing element 11 includes multiple heating elements arranged along a first direction. A power supply assembly 70 is used to selectively supply electrical energy to each heating element. The first direction is the extending direction of the aerosol generating article 200.

[0079] The power supply assembly 70 is used to selectively provide power to each heating element. In other words, the power supply assembly 70 is used to selectively connect to each heating element. That is, it can conduct different numbers or different positions of heating elements as needed to meet the atomization requirements of the first atomizer 10.

[0080] The first direction is the extension direction of the aerosol generating article 200. In other words, the first direction is the direction in which the aerosol generating article 200 is inserted into the receiving chamber 121. This allows multiple heating elements to cover as much area as possible along the first direction, thereby further improving the versatility of the aerosol generating device 100.

[0081] The first atomizing element 11 is provided with multiple heating elements. By conducting different numbers or different positions of the heating elements, the output power and heating position of the first atomizing element 11 can be adjusted. On the one hand, it can be applied to different aerosol generating products 200. On the other hand, it is convenient to adjust the output power of the first atomizing element 11.

[0082] It is understood that the position or size of the aerosol generating medium section 210 of different aerosol generating articles 200 may be different. In this embodiment, the first atomizing element 11 can adapt to different aerosol generating articles 200 by connecting the electrical circuit of the heating element at different positions, that is, by controlling the heating element corresponding to the aerosol generating medium section 210 to work.

[0083] In related technologies, aerosol generating devices have poor adaptability to different aerosol generating products. If it is necessary to inhale or experience different aerosol generating products, different aerosol generating devices are required, resulting in high usage costs and inconvenience in carrying them.

[0084] In the aerosol generating device 100 of this application embodiment, the first atomizing element 11 is provided with multiple heating elements. The multiple heating elements can be selected to work only a single heating element or multiple heating elements to work simultaneously according to different usage scenarios, so as to adapt to the atomization of different types of aerosol generating products 200. In addition, in the embodiment where a single heating element works, heating elements at different positions can also be selected to work, so as to further adapt to the atomization of different types of aerosol generating products 200.

[0085] In some embodiments, please refer to Figures 3 to 4The number of heating elements is n. The first atomizing element 11 also includes a common lead 114 and n sub-leads 115. The common lead 114 is electrically connected to all heating elements, and the n sub-leads 115 are electrically connected to the n heating elements one by one.

[0086] Here, a common lead 114 is connected to all the heating elements, and n sub-leads 115 are electrically connected to the n heating elements one by one. In other words, each heating element is connected in parallel in the circuit.

[0087] For example, the first atomizing element 11 also includes a common electrode, which is electrically connected to n heating elements at the same time, and a common lead 114 is electrically connected to the common electrode.

[0088] Here, by setting as few leads as possible to achieve parallel connection of multiple heating elements, it is beneficial to reduce the assembly difficulty of the aerosol generating device 100 and simplify the structure of the aerosol generating device 100.

[0089] For example, the electrical connection between the power supply assembly 70 and the second atomizer 20 can be controlled by a control switch, or the airflow sensor threshold of the second atomizer 20 can be triggered when the inhaled airflow passes through the airway, thereby realizing the electrical connection between the power supply assembly 70 and the second atomizer 20.

[0090] In some embodiments, please refer to Figure 3 At least one of the multiple heating elements has a different dimension along the first direction than the other heating elements.

[0091] In other words, not all heating elements have the same dimensions along the first direction. For example, all heating elements may have different dimensions along the first direction, or some heating elements may have the same dimensions along the first direction, while others may have different dimensions along the first direction.

[0092] Here, by setting the dimensions of at least one of the multiple heating elements to be different from those of the other heating elements along the first direction, it is advantageous for the first atomizing element 11 to output more different output powers in order to better adapt to the aerosol generating article 200.

[0093] In some embodiments, please refer to Figure 3 Among the multiple heating elements, the heating element closest to the lip end of the aerosol generating article 200 has the smallest size along the first direction.

[0094] For example, the first direction is, for instance, the height direction of the aerosol generating device 100.

[0095] The heating element closest to the lip end of the aerosol generating product 200 among the multiple heating elements is the topmost heating element.

[0096] Here, by setting the size of the heating element closest to the lip end of the aerosol generating article 200 in the first direction to be the smallest among the multiple heating elements, the heating element heats up faster, which facilitates faster and more complete atomization of the corresponding aerosol generating medium section 210, which is beneficial to improve the taste and improve the consistency of inhalation.

[0097] In some embodiments, please refer to Figures 3 to 4 The multiple heating elements include a first heating element 111, a second heating element 112, and a third heating element 113, which are arranged sequentially along the direction from the proximal lip end to the distal lip end of the aerosol generating article 200.

[0098] It should be noted that the first heating element 111, the second heating element 112, and the third heating element 113 are heating elements located at three different positions.

[0099] In this embodiment, at least one of the first heating element 111, the second heating element 112, and the third heating element 113 can be selected to work according to different usage scenarios to adapt to the atomization of different types of aerosol generating articles 200. For example, the corresponding first heating element 111, the second heating element 112, and the third heating element 113 can be selected to work according to the position of the aerosol generating medium section 210 of different types of aerosol generating articles 200.

[0100] In some embodiments, please refer to Figures 3 to 4 The dimension of the first heating element 111 along the first direction is less than or equal to the dimension of the second heating element 112 along the first direction, and the dimension of the second heating element 112 along the first direction is less than or equal to the dimension of the third heating element 113 along the first direction.

[0101] For example, such as Figure 3 As shown, the dimension of the first heating element 111 along the first direction is represented by L1, the dimension of the second heating element 112 along the first direction is represented by L2, and the dimension of the third heating element 113 along the first direction is represented by L3.

[0102] Thus, by combining the first heating element 111, the second heating element 112, and the third heating element 113 and their corresponding positional relationships, it is possible to adapt to as many different aerosol generating products 200 as possible. Furthermore, by setting the dimensions of the first heating element 111, the second heating element 112, and the third heating element 113 to a gradient along the first direction, it is beneficial to reduce the temperature difference between adjacent heating elements, thereby further improving the taste and suction consistency.

[0103] For example, by providing a relatively large third heating element 113 along the first direction at the distal lip end of the aerosol generating article 200, it is beneficial to provide a corresponding aerosol generating medium section 210 at the distal lip end of the aerosol generating article 200. Even if the aerosol generating medium section 210 is atomized only by the third heating element 113, that is, while improving the versatility of the aerosol generating device 100, the power consumption of the aerosol generating device 100 can be reduced as much as possible.

[0104] In some embodiments, please continue reading Figures 3 to 4 The sum of the dimensions of the first heating element 111 along the first direction and the dimensions of the second heating element 112 along the first direction is greater than or equal to the dimensions of the third heating element 113 along the first direction.

[0105] In other words, the dimension of the third heating element 113 along the first direction cannot be infinitely large, so that the dimension of the third heating element 113 along the first direction is less than or equal to the sum of the dimension of the first heating element 111 along the first direction and the dimension of the second heating element 112 along the first direction. In this way, while improving the aerosol generating device 100, the structural compactness of the aerosol generating device 100 can be improved as much as possible.

[0106] Understandably, if the sum of the dimensions of the first heating element 111 along the first direction and the second heating element 112 along the first direction is less than or equal to the dimension of the third heating element 113 along the first direction, then the difference between the dimension of the third heating element 113 along the first direction and the dimensions of the first heating element 111 and the second heating element 112 along the first direction is large. This may result in a large temperature difference between adjacent heating elements at the beginning of atomization. However, by setting the sum of the dimensions of the first heating element 111 along the first direction and the second heating element 112 along the first direction to be greater than or equal to the dimension of the third heating element 113 along the first direction, the difference between the dimensions of the first heating element 111, the second heating element 112, and the third heating element 113 along the first direction can be reduced. This helps to reduce the temperature difference between adjacent heating elements, thereby further improving the taste and vaping consistency.

[0107] In some embodiments, please refer to Figures 3 to 4 The size of the first heating element 111 along the first direction is in the range of 2.8mm to 4.5mm.

[0108] The dimension of the first heating element 111 along the first direction can be any one of 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.1mm, 4.2mm, 4.3mm, or 4.5mm, or a value between any two of them.

[0109] In some embodiments, please refer to Figures 3 to 4 The dimensions of the second heating element 112 along the first direction are in the range of 4.5 mm to 7.5 mm.

[0110] The dimension of the second heating element 112 along the first direction can be any one of 4mm, 4.1mm, 4.2mm, 4.3mm, 4.5mm, 4.8mm, 5mm, 5.2mm, 5.5mm, 5.8mm, 6mm, 6.3mm, 6.5mm, 6.55mm, 6.7mm, 7mm, 7.1mm, 7.2mm, 7.3mm, 7.5mm, or a value between any two.

[0111] In some embodiments, please refer to Figures 3 to 4 The third heating element 113 has a dimension in the first direction ranging from 6 mm to 8 mm.

[0112] The dimension of the third heating element 113 along the first direction can be any one of 6mm, 6.3mm, 6.5mm, 6.7mm, 7mm, 7.1mm, 7.15mm, 7.2mm, 7.3mm, 7.5mm, 7.6mm, 7.8mm, or 8mm, or any value between two of them.

[0113] The appropriate size range of the first heating element 111, the second heating element 112, and the third heating element 113 improves the structural compactness of the aerosol generating device 100 while enhancing its versatility.

[0114] In some embodiments, please refer to Figure 3 The aerosol generating article 200 includes an aerosol generating medium section 210, and a first atomizing element 11 is used to atomize the aerosol generating medium section 210. In the first direction, the third heating element 113 cannot completely cover the aerosol generating medium section 210.

[0115] In other words, in the first direction, the aerosol generating medium section 210 is not completely covered by the third heating element 113.

[0116] For example, the distal lip of the aerosol generating medium segment 210 may be exposed to the third heating element 113, the proximal lip of the aerosol generating medium segment 210 may be exposed to the third heating element 113, or both the distal and proximal lip of the aerosol generating medium segment 210 may be exposed to the third heating element 113.

[0117] Understandably, by setting the third heating element 113 to not completely cover the aerosol generating medium section 210, the heating range of the third heating element 113 on the aerosol generating medium section 210 can be reduced, thereby shortening the temperature rise time and improving the atomization efficiency. In addition, it is also beneficial to reduce the possibility that all water vapor in the aerosol generating product 200 will be released in the early stage of atomization, thereby improving the problem of aerosol burning the mouth.

[0118] In some embodiments, please refer to Figure 3 The dimension of the third heating section 113 along the first direction is smaller than the dimension of the aerosol generating medium section 210 along the first direction.

[0119] For example, the aerosol generating medium section 210 has a dimension greater than or equal to 10 mm along the first direction, while the third heating part 113 has a dimension in the range of 6 mm to 8 mm along the first direction, so that the dimension of the third heating part 113 along the first direction is smaller than the dimension of the aerosol generating medium section 210 along the first direction.

[0120] Here, by setting the size of the third heating element 113 along the first direction to be smaller than the size of the aerosol generating medium section 210 along the first direction, it is beneficial to improve atomization efficiency and inhalation experience.

[0121] In some embodiments, please refer to Figure 3 The aerosol generating article 200 includes an aerosol generating medium section 210, and the distance between the proximal lip end of the heating part and the proximal lip end of the aerosol generating article 200 is less than or equal to the distance between the proximal lip end of the aerosol generating medium section 210 and the proximal lip end of the aerosol generating article 200.

[0122] This facilitates the full atomization of the aerosol generation medium section 210.

[0123] In other words, the distance between the proximal lip of the heating element and the distal lip of the aerosol generating article 200 is greater than or equal to the distance between the proximal lip of the aerosol generating medium section 210 and the distal lip of the aerosol generating article 200, that is, the top of the heating element is higher than the top of the aerosol generating medium section 210, or the top of the heating element is flush with the top of the aerosol generating medium section 210.

[0124] It should be noted that the first atomizer 10 has multiple working modes, and different working modes can be applied to different aerosol generating products 200, thereby improving the versatility of the aerosol generating device 100.

[0125] In some embodiments, please refer to Figures 3 to 4 The aerosol generating device 100 includes a first operating state, in which the power supply component 70 is electrically connected to the first heating element 111 and the second heating element 112.

[0126] In other words, at this time, the first heating element 111 and the second heating element 112 are in working condition and can atomize the aerosol generating product 200. This is applicable to the aerosol generating product 200 in the aerosol generating medium section 210 corresponding to the positions of the first heating element 111 and the second heating element 112.

[0127] For example, such as Figure 3 Of the three aerosol generating articles 200 shown, the one closest to the heating element 12 can be atomized together by the first heating element 111 and the second heating element 112.

[0128] For example, if the aerosol generating medium section 210 is relatively long, the aerosol generating medium section 210 can be atomized by the first heating element 111 and the second heating element 112 together.

[0129] In some embodiments, please refer to Figures 3 to 4 The aerosol generating device 100 includes a second operating state in which the power supply assembly 70 is electrically connected to the second heating element 112.

[0130] In other words, at this time, the second heating element 112 is in working condition and can atomize the aerosol generating product 200, which is applicable to the aerosol generating medium section 210 corresponding to the position of the second heating element 112.

[0131] For example, such as Figure 3 Of the three aerosol generating articles 200 shown, the middle one can be atomized by the second heating element 112.

[0132] In some embodiments, please refer to Figures 3 to 4 The aerosol generating device 100 includes a third operating state in which the power supply assembly 70 is electrically connected to the third heating element 113.

[0133] In other words, at this time, the third heating element 113 is in working condition and can atomize the aerosol generating product 200, which is applicable to the aerosol generating medium section 210 corresponding to the position of the third heating element 113.

[0134] For example, such as Figure 3 The aerosol generating product 200 furthest from the heating element 12 among the three aerosol generating products 200 shown can be atomized by the third heating element 113.

[0135] In some embodiments, please refer to Figures 3 to 4The first atomizing element 11 includes a heating element 12, the heating element 12 has a receiving chamber 121 inside, and a plurality of heating elements are disposed on the outer wall or inner wall of the receiving chamber 121.

[0136] For example, the heating element 12 is a heating tube, and the internal space of the heating tube forms a receiving chamber 121.

[0137] Multiple heating elements are arranged sequentially along the axial direction of the heating element 12. These heating elements can be located on the outer side wall or the inner side wall of the heating element 12.

[0138] For example, the heating element may be a heating film.

[0139] Here, by setting multiple heating elements on the outer wall of the receiving chamber 121, the heat generated by the heating elements can be transferred to the aerosol generating product 200 set in the heating element 12 through the heating element 12. In addition, the damage to the heating elements can be reduced when taking the aerosol generating product 200 out of the chamber.

[0140] Here, by setting multiple heating elements on the inner wall of the receiving chamber 121, the multiple heating elements can directly heat and atomize the aerosol generating product 200, which is beneficial to improving the atomization efficiency of the first atomizing element 11.

[0141] For example, the aerosol generating device 100 also includes a heat insulation component 13, which surrounds the heating element 12 to reduce the transfer of heat from the heating element to the surrounding components or the housing 60 of the aerosol generating device 100, thereby improving the reliability of the aerosol generating device 100.

[0142] For example, the thermal insulation component 13 includes, but is not limited to, thermal insulation methods such as aerogel, air layer, and vacuum tube.

[0143] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6 The second atomizer 20 includes an outlet channel 26, through which the atomizing element 21 discharges the aerosol generated by atomizing the aerosol generating matrix into the outlet channel 26. The aerosol generating device 100 also includes a connector 30 with a connecting channel 31, through which the outlet channel 26 is connected to the receiving chamber 121.

[0144] Here, the specific structure of the second atomizer 20 is not limited. Exemplarily, the second atomizer 20 includes a housing 23 and an atomizing seat 24, at least a portion of which is disposed within the housing 23 and defines a liquid storage chamber 22 with the housing 23. The atomizing base 24 includes an atomizing chamber 25 and a liquid inlet channel 243. The second atomizing element 21 is disposed in the atomizing chamber 25. The aerosol generating matrix in the liquid storage chamber 22 flows to the second atomizing element 21 through the liquid inlet channel 243. The second atomizing element 21 atomizes the aerosol generating matrix to generate aerosol. The aerosol flows through the atomizing chamber 25 to the gas outlet channel 26, and then flows through the connecting channel 31 to the receiving chamber 121. It then mixes with the aerosol generated by the atomized aerosol generating product 200 of the first atomizing element 11 to form a "new" aerosol for user use. Alternatively, it enters the interior of the aerosol generating product 200 in the receiving chamber 121, carrying out the effective components in the aerosol generating product 200 to form a "new" aerosol for user use.

[0145] For example, please refer to Figure 6 The atomizing seat 24 includes an upper atomizing seat 241 and a lower atomizing seat 242, which together form an atomizing cavity 25.

[0146] Here, by setting the connector 30, on the one hand, it is convenient to install the first atomizer 10 and the second atomizer 20, and on the other hand, it is convenient to connect the air passage between the first atomizer 10 and the second atomizer 20. The aerosols generated by the first atomizer 10 and the second atomizer 20 can be mixed to form a "new" aerosol, thereby bringing a new vaping experience to the user.

[0147] For example, the sealing connection between the connector 30 and the first atomizer 10 helps to improve the gas seal, thereby improving the problem of aerosol leakage.

[0148] For example, the sealing connection between the connector 30 and the second atomizer 20 helps to improve the gas seal, thereby improving the problem of aerosol leakage.

[0149] For example, please refer to Figure 2 The connector 30 includes a first flange 32 and a connecting bracket 33, which define a connecting channel 31.

[0150] For example, please refer to Figure 2 and Figure 7 The first flange 32 has a stepped surface 321 on the side opposite to the second atomizer 20. The stepped surface 321 is used to abut against the aerosol generating article 200 and / or the heating element 12 to achieve positioning of the aerosol generating article 200 and / or the heating element 12.

[0151] For example, the first flange 32 is formed with a guide protrusion to guide the aerosol-generating article 200 and guide the aerosol-generating article 200 to the step surface 321.

[0152] For example, the connector 30 is connected to the housing 60 via the connecting bracket 33, which not only enables the connector 30 to be connected to the housing 60, but also facilitates the connection of the connector 30 to form a connecting channel 31.

[0153] Here, the first flange 32 and the connecting bracket 33 can be an integral structure or a separate structure. In the embodiment where the first flange 32 and the connecting bracket 33 are separate structures, the first flange 32 and the connecting bracket 33 are sealed together.

[0154] For example, the first flange 32 can be made of a high-temperature resistant material. The material of the first flange 32 includes, but is not limited to, ceramics, zirconium oxide, glass, PEEK, PTFE, etc., and its main function is to support the heating element 12.

[0155] For example, the aerosol generating device 100 further includes a sealing member 50, which is sandwiched between the connector 30 and the second atomizer 20 to seal the gap between the connector 30 and the second atomizer 20.

[0156] For example, please refer to Figure 2 The aerosol generating device 100 also includes a second flange 40, through which the end of the heating element 12 away from the second atomizer 20 is installed to the housing 60.

[0157] For example, the second flange 40 can be made of a high-temperature resistant material. The material of the second flange 40 includes, but is not limited to, ceramics, zirconium oxide, glass, PEEK, PTFE, etc., and its main function is to support the heating element 12.

[0158] When multiple heating elements are heated simultaneously or for a period of time, the multiple heating elements have the same temperature control curve trend, which helps to improve the consistency of aerosols.

[0159] For example, multiple heating elements can all heat up first and then cool down.
