However, existing aerosol generating devices only have a single heating unit, and devices using different heating methods are not interchangeable. This fails to meet the heating needs of various types of aerosol products, preventing consumers from adjusting the device to their preferences. Furthermore, existing aerosol generating devices cannot accommodate multiple users sharing the device, making them very inconvenient. Additionally, the limited energy storage of the power supply unit in existing aerosol generating devices results in weak battery life, making them unsuitable for continuous use by multiple users in shifts.

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0032] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are merely used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0034] The aerosol generating device uses the principle of heating without combustion to heat aerosol generating product A, so as to generate an aerosol for user use.

[0035] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, aerosolized, are in the form of a spray or jet, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0036] Aerosol-generating article A is generally formed from molded paper and contains a substance capable of generating aerosols. This substance is any suitable compound or mixture of compounds that facilitates aerosol formation during use. Suitable aerosol-generating articles A are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. The substance may also include nicotine, water, glycerol (also known as glycerol) having a higher boiling point than nicotine, propylene glycol, plant-based materials, or homogeneous plant substrates.

[0037] Please see Figures 1 to 11 The aerosol generating device includes multiple aerosol generating bodies 10 and a battery module 20. Each of the multiple aerosol generating bodies 10 has a different heating unit 14, which is used to heat different types of aerosol generating products A to generate aerosols. The battery module 20 is detachably connected to the multiple aerosol generating bodies 10 and is used to supply power or charge the aerosol generating bodies 10.

[0038] It is understandable that aerosol generating products A come in various types (such as fifth-generation HEETS and sixth-generation TEREA), each with its own heating method. Furthermore, different aerosol generating products A may have different shapes or lengths. Therefore, even with the same heating method, the corresponding heating unit 14 (including shape and size) will differ. Currently, because aerosol generating devices can only heat one type of aerosol generating product A, devices with different heating methods are not interchangeable. This forces users to switch to different aerosol generating devices when experiencing different aerosol generating products A, causing significant inconvenience. Additionally, the inherent limitations of the aerosol generating devices prevent multiple users from sharing them.

[0039] This application sets up multiple aerosol generating bodies 10, each with a different heating unit 14. This heating unit 14 can adapt to aerosol generating products A of different shapes or lengths, as well as aerosol generating products A with different heating methods, resulting in excellent suction performance for the aerosol generating products A and meeting the matching needs of users for different heating methods. Since there are multiple aerosol generating bodies 10, the sharing needs among multiple users can be met. Due to the inclusion of a battery module 20, users can selectively connect the battery module 20 to different aerosol generating bodies 10. During user use, the battery module 20 can charge or supply power to the aerosol generating bodies 10, thereby improving the battery life of the assembled aerosol generating device, meeting the user's need for long-term continuous use, and contributing to an improved user experience.

[0040] Based on the heating method, heating units 14 can be categorized into electromagnetic induction heating units, contact resistance heating units, and infrared heating units. Electromagnetic induction heating generates heat by inducing a current in a metal conductor through an alternating magnetic field. Heating units 14 in aerosol generating devices typically include a magnetic induction coil and a sensor made of a magnetically conductive metal material. When the sensor is placed in the alternating magnetic field generated by the energized electromagnetic induction coil, eddy currents are generated inside the sensor. The Joule heating effect of these eddy currents causes heating unit 14 to heat up rapidly, thereby heating the aerosol-generated product A. Contact resistance heating utilizes the Joule heating generated when current passes through a resistive material to conduct heat to the aerosol-generated product A. The resistive material generally includes conductive metal or conductive ceramic materials. When current passes through heating unit 14, electrical energy is converted into heat energy, thereby heating the aerosol-generated product A. Infrared heating utilizes the radiant energy of infrared radiation to achieve heating.

[0041] Contact resistance heating can also be categorized into center resistance heating and circumferential resistance heating based on the heating location. Center resistance heating uses a needle-type or plate-type heating element inserted into the aerosol-generated product A for heating, while circumferential resistance heating uses a heating tube surrounding the aerosol-generated product A for heating.

[0042] In some embodiments, the heating units 14 of the plurality of aerosol generating bodies 10 are selected from any one of electromagnetic induction heating units, contact resistance heating units, infrared heating units, and hot airflow heating units. When selected from electromagnetic induction heating units, the heating units 14 of the aerosol generating bodies 10 can select one or more of the following heating methods: central heating, circumferential heating, and bottom hot airflow heating, or a combination of two of these methods. For example, the sensing element is placed inside the aerosol generating article A to heat it in a central heating manner; or, the sensing element is set as a needle (or rod) inserted inside the aerosol generating article A to heat it in a central heating manner; or, the sensing element is placed on the periphery of the aerosol generating article A, such as by setting the sensing element as a cylindrical structure to heat it in a circumferential heating manner; or, the sensing element is placed at the end of the aerosol generating article A to heat the passing hot airflow, thereby heating it in a bottom hot airflow heating manner. When selected from resistance heating units, the heating element can also be placed inside or on the periphery of the aerosol generating article A, using central heating and circumferential heating methods to generate the aerosol generating article A. When choosing infrared heating, a sleeve that can utilize the infrared effect can be selected as the heating element, thus allowing for circumferential heating. When using central or bottom hot airflow heating, the process is the same as other options, involving only a change in the position of the heating element, which will not be elaborated here.

[0043] In specific applications, the system includes a first aerosol generating body 11, a second aerosol generating body 12, and a third aerosol generating body 13, and correspondingly includes a first heating unit 141, a second heating unit 142, and a third heating unit 143. The first heating unit 141 can be selected from an electromagnetic induction heating unit, the second heating unit 142 can be selected from a resistance heating unit, and the third heating unit 143 can be selected from an infrared heating unit. Figure 2 As shown, the first heating unit 141 is selected from a resistance heating unit, and its heating element is a heating needle (or heating rod), which is suitable for the 5th generation HEETS. It is inserted inside the aerosol generating product A and uses a central heating method. The second heating unit 142 can be selected from an electromagnetic induction heating unit, and its sensing element is located inside the aerosol generating product A, which is suitable for the 6th generation TEREA. The third heating unit 143 is also selected from a resistance heating unit, and its heating element is located at the end (bottom) of the aerosol generating product A. After the airflow enters the heating unit 14 from the outside, it is heated into a hot airflow by the heating element. At the same time, an auxiliary heating structure is also provided around the circumference of the aerosol generating product A. It uses a combination of circumferential heating and bottom hot airflow heating, which is suitable for aerosol generating products A without plugs.

[0044] Please see Figure 3In some embodiments, the aerosol generating body 10 also includes a power supply unit 16, which is electrically connected to the heating unit 14 and is used for energy storage and power supply to the heating unit 14. When the aerosol generating body 10 is connected to the battery module 20, the battery module 20 can charge the power supply unit 16 of the aerosol generating body 10. Through the provision of the power supply unit 16, the aerosol generating body 10 can operate independently as an aerosol generating device. Since the battery capacity of a single aerosol generating body 10 is limited, connecting the battery module 20 to the aerosol generating body 10 not only provides real-time power when the aerosol generating body 10 is working, but also allows for charging when the aerosol generating body 10 is not working.

[0045] Please see Figures 4 to 7 In some embodiments, the battery module 20 may be selectively arranged side-by-side with one of the plurality of aerosol generating bodies 10 along the vertical Y direction, and each aerosol generating body 10 operates independently. The plurality of aerosol generating bodies 10 have their own independent control structure and power supply unit 16, and one of the aerosol generating bodies 10 adapted to the aerosol generating product A can be selected to operate, so that the arrangement of the plurality of aerosol generating bodies 10 can meet the synchronous use of multiple users.

[0046] In some embodiments, at least two of the plurality of aerosol generating bodies 10 are arranged side by side with the battery module 20 along the vertical Y direction. The at least two aerosol generating bodies 10 and the battery module 20 are electrically connected to each other, and the positions of the at least two aerosol generating bodies 10 can be interchanged, allowing users to assemble them arbitrarily according to their preferences. When going out, users can also carry the aerosol generating body that best matches their daily habits. Figures 4 to 6 As shown, the aerosol generating bodies 10 are sequentially located at the same end of the battery module 20 along the vertical direction Y. The aerosol generating body 10 at the top is used to heat the aerosol generating product A, and the remaining aerosol generating bodies 10 are used to achieve electrical connection between the top aerosol generating body 10 and the battery module 20. Users can choose any aerosol generating body 10 to be located at the top according to their preference. In this embodiment, conductive structures are provided on two opposite sides of the aerosol generating body 10, and these conductive structures are also electrically connected to each other, so that the battery module 20 can sequentially supply power or charge the top aerosol generating product A through the remaining aerosol generating products A.

[0047] In some embodiments, as shown in FIG7, only one aerosol generating body 10 is located at the top of the battery module 20 for heating the aerosol generating product A, while the other aerosol generating bodies 10 are located at the bottom of the battery module 20. When the user needs to use different aerosol generating products A, the corresponding aerosol generating bodies 10 can be interchangeably set at the top of the battery module 20. When the extension length of the aerosol generating device is shorter than the grip length requirement, one, two, three or more aerosol generating bodies 10 can be set at the bottom of the battery module 20 to lengthen the overall extension length of the aerosol generating device, thereby meeting the grip requirements of different users.

[0048] In some embodiments, the aerosol generating body 10 further includes a first electrode portion 17, and the battery module 20 further includes a second electrode portion 22. The aerosol generating body 10 includes a first housing 15, a heating unit 14 is disposed within the first housing 15, and the first electrode portion 17 is disposed on the first housing 15. The battery module 20 includes a second housing 21, and the second electrode portion 22 is disposed on the second housing 21. The first housing 15 and the second housing 21 are detachably connected, and the first electrode portion 17 and the second electrode portion 22 are detachably electrically connected, which facilitates the selection of one or more aerosol generating bodies 10 or at least two aerosol generating bodies 10 to be connected to the battery module 20.

[0049] It should be emphasized that when at least two aerosol generating bodies 10 are disposed at the same end of the battery module 20, the conductive structure on the aerosol generating body 10 is used to enable the battery module 20 to supply power or charge the aerosol generating body 10 at the top. This conductive structure can be detachably connected to the first housing 15, thereby preventing a short circuit between the conductive structure on the aerosol generating device in operation and the first electrode part 17 and the second electrode part 22 in series. Of course, the conductive structure can also be integrally formed with the first housing 15, but it should be provided with an insulating structure between itself and the first electrode part 17 and the heating unit 14, thereby also preventing a short circuit in use.

[0050] Please see Figure 8 The first housing 15 is recessed inward to form a first electrode groove 153. The first electrode part 17 is disposed in the first electrode groove 153. At least a portion of the second electrode part 22 protrudes from the second housing 21. The second electrode part 22 can be inserted into the first electrode groove 153 and is electrically connected to the first electrode part 17.

[0051] Please see Figure 9The second housing 21 is recessed inward to form a second electrode groove 211, and a second electrode portion 22 is disposed within the second electrode groove 211. At least a portion of the first electrode portion 17 protrudes from the first housing 15. The first electrode portion 17 can be inserted into the second electrode groove 211 and electrically connected to the second electrode portion 22. In this embodiment, the first electrode portion 17 and the second electrode portion 22 are connected by insertion, which can realize both circuit connection and connection between the first housing 15 and the second housing 21, thereby simplifying the structure of the aerosol generating body 10 and the battery module 20.

[0052] In some embodiments, the first electrode portion 17 is flush with the surface of the first housing 15, and the second electrode portion 22 is flush with the surface of the second housing 21, with the first electrode portion 17 and the second electrode portion 22 in contact for electrical conductivity. This embodiment facilitates the placement of the aerosol generating body 10 on a flat object.

[0053] Please see Figure 10 and Figure 11 In some embodiments, the first housing 15 has a first sidewall 151 and a second sidewall 152 disposed opposite to each other in the vertical direction Y. The first sidewall 151 is provided with a first connecting structure 1511, the second sidewall 152 is provided with a second connecting structure 1521, and the second housing 21 is provided with a third connecting structure 212. The first connecting structure 1511 is used to detachably connect with the second connecting structure of the adjacent aerosol generating body 10 or to the third connecting structure 212. When at least two aerosol generating bodies 10 and the battery module 20 are arranged side by side, and the aerosol generating bodies 10 are all located at the same end of the battery module 20, the first sidewall 151 and the second sidewall 152 are provided with conductive structures for electrical connection, or the conductive structures extend from the first sidewall 151 to the second sidewall 152, so that circuit conduction can be achieved after multiple aerosol generating bodies 10 are arranged side by side.

[0054] In some embodiments, the first connecting structure 1511, the second connecting structure 1521 and the third connecting structure 212 are connected by a detachable connection method selected from magnetic connection, interlocking connection or adhesive connection.

[0055] In use, the first sidewall 151 can be the end from which the aerosol is discharged, and the second sidewall 152 is the opposite end. When the first connecting structure 1511, the second connecting structure 1521 and the third connecting structure 212 are connected by interlocking, one of the two interconnected structures is a protrusion and the other is a groove. For example, if the third connecting structure 212 is a protrusion, then the second connecting structure 1521 is a groove. If the first connecting structure 1511 is a protrusion and the third connecting structure 212 is a groove, then the second connecting structure 1521 is a protrusion and the first connecting structure 1511 is a groove.

[0056] In some embodiments, the first connecting structure 1511 may also include at least one groove and at least one protrusion. Correspondingly, the protrusion is connected to the groove, and the groove is connected to the protrusion. In specific design, the fit and connection are guaranteed. The shape of the protrusion may be spherical, hemispherical, cylindrical, cuboid, triangular pyramid, polygonal prism, etc., and the groove is adapted to its shape.

[0057] To simplify the structure of the aerosol generating body 10 and the battery module 20, the first electrode part 17 can be combined with the second connection structure 1521 on the second sidewall 152, and the third connection structure 212 on the battery module 20 can be combined with the second electrode part 22, that is, both the second connection structure 1521 and the third connection structure 212 are made to be conductive.

[0058] In some embodiments, a heating cavity is formed within the heating unit 14, the length of which is controlled between 2.2cm and 2.5cm to accommodate the size of the aerosol-generating article A. To meet the heating length requirements of the aerosol-generating article A, and also to meet the requirement of being compact and easy to hold, the length of a single aerosol generating body 10 in the extending direction ranges from 3cm to 4cm, and / or the length of the battery module in the extending direction also ranges from 3cm to 4cm.

[0059] In some embodiments, the multiple aerosol generating bodies 10 and battery modules 20 are shaped like cuboids, cylinders, rounded cuboids, or polygonal prisms. For ease of grip, when a single aerosol generating body 10 is a cuboid, its length is 2cm-5cm and its width is 1cm-2cm. When a single aerosol generating body 10 is a cylinder, its radius is 1cm-2cm. The size limitations of the aerosol generating bodies 10 and battery modules 20 result in a lightweight and compact aerosol generating device, making it easy to hold and carry, thus improving user comfort.

[0060] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
