Description

Technical Field

[0001] This application relates to the technical field of aerosol generation devices, and particularly to modular aerosol generation devices and individual aerosol generation device units. Background Technology

[0002] In traditional modular e-cigarettes, there is a considerable distance between the inner wall of the mouthpiece's outlet and the splicing surface. When multiple units are combined, the aerosol streams exiting from adjacent units lack effective guidance and mixing before reaching the user's mouth. This results in the aerosol streams from different units forming independent and separate airflows near the outlet, ultimately delivering multiple discontinuous aerosol streams to the user's mouth. This leads to a fragmented and unsatisfactory taste experience, failing to meet the user's demand for a better and more consistent flavor profile. Utility Model Content

[0003] To address the above issues, this application proposes a spliced ​​aerosol generation device. This design sets the central axes of the air inlet and outlet of the nozzle structure to be non-collinear, allowing the outlet to be close to the splicing surface and causing the inner surfaces of adjacent outlets to converge. This design provides an initial mixing area for the aerosol flow near the splicing surface, shortening the distance of airflow separation. The converging inner surfaces further guide the airflow fusion, ultimately forming a more coherent and uniform aerosol, solving the problem of multi-stream separation and improving the user experience.

[0004] This application provides a spliced ​​aerosol generating device, comprising: at least two aerosol generating device units, each aerosol generating device unit including an atomizing core for atomizing an aerosol matrix to generate an aerosol and a nozzle structure in fluid communication with the atomizing core; wherein, each aerosol generating device unit has a splicing surface that extends at least partially to the nozzle structure, at least two aerosol generating device units are joined together by contacting the splicing surface, and the nozzle structure is provided with an air inlet spaced apart from the splicing surface and an air outlet communicating with the air inlet, the central axis of the air outlet being non-collinear with the central axis of the air inlet, and the central axis of the air outlet being offset toward the splicing surface.

[0005] As one embodiment, the aerosol generating device is provided with an aerosol channel, which has an air outlet that connects with the air inlet of the nozzle structure.

[0006] As one embodiment, the air outlet is positioned directly opposite the air inlet, or the central axis of the air outlet is substantially coincident with the central axis of the air inlet.

[0007] As one embodiment, the aerosol channel is spaced apart from the splicing surface.

[0008] As one embodiment, the aerosol generating device unit includes a storage cavity for containing an aerosol matrix, the aerosol channel passing through the storage cavity, and the aerosol channel being offset from the central axis of the storage cavity towards the splicing surface.

[0009] As one embodiment, the air outlet expands in a trumpet shape, and one side of the inner surface of the air outlet approaches or terminates at the splicing surface.

[0010] As one embodiment, the nozzle structure includes a wall defining the air inlet and the air outlet, and a portion of the wall near the air inlet is inclined toward the splicing surface to form a thickened structure.

[0011] As one embodiment, the longitudinal projection of the air outlet partially overlaps with the longitudinal projection of the aerosol channel, and the area of ​​the overlapping area is greater than half of the projected area of ​​the aerosol channel.

[0012] As one embodiment, the inner surfaces of the outlets of at least two of the aerosol generating device units approach and come close to each other.

[0013] As one embodiment, a portion of the inner surface of the air outlet includes a straight section substantially parallel to the splicing surface and a curved section inclined toward the splicing surface.

[0014] This application provides a single aerosol generating device, comprising: an atomizing core for atomizing an aerosol matrix to generate an aerosol; and a nozzle structure in fluid communication with the atomizing core. The outer surface of the single aerosol generating device has a splicing surface, and the nozzle structure is provided with an air inlet spaced apart from the splicing surface and an air outlet connected to the air inlet. The central axis of the air outlet is not collinear with the central axis of the air inlet, and the central axis of the air outlet is offset toward the splicing surface.

[0015] This application proposes a splicing aerosol generation device. By designing the air inlet and outlet of the nozzle structure to be non-collinear, the air outlet can be close to the splicing surface, and the inner surfaces of adjacent air outlets tend to converge. This design provides an initial mixing area for the aerosol flow near the splicing surface, shortening the distance of airflow separation. The converging inner surfaces further guide the airflow fusion, ultimately forming a more coherent and uniform aerosol, solving the problem of multi-stream airflow separation, and improving the user experience.

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.

[0033] This application provides a modular aerosol generating device 100, such as... Figure 1 As shown, the modular aerosol generator 100 can be used to atomize an aerosol-generating matrix to generate aerosols for consumption by users. Figures 1-4As shown, the modular aerosol generator 100 includes at least two aerosol generator units 10. Each aerosol generator unit 10 includes an atomizing core 1, a nozzle structure 2, a splicing surface 3, a limiting member 31, a magnetic attraction structure 32, and an electronic connection terminal 33. The splicing surface 3 is flat and has the limiting member 31, magnetic attraction structure 32, and electronic connection terminal 33 disposed thereon. When there are two or more aerosol generator units 10, the splicing surfaces 3 of adjacent units are fitted together and connected by the limiting member 31 and the magnetic attraction structure 21. The limiting component 31 includes a mutually cooperating and precisely corresponding protruding structure 311 and groove structure 312, ensuring that the individual units achieve precise and repeatable alignment, preventing relative displacement caused by accidental collisions or vibrations after splicing, and ensuring the overall stability of the device structure. The magnetic structure 32 provides the main connection and fastening force. Compared with purely mechanical buckles, it allows users to quickly splice the device by simply approaching it after the limiting component 31 is precisely positioned, greatly improving the convenience and efficiency of user operation. At the same time, the magnetic connection also allows for relatively easy separation of individual units, making it convenient to carry, share, or replace. In conjunction with the limiting component 31, the magnetic structure can effectively resist minor external forces in daily use, preventing the spliced ​​device from accidentally falling apart. In addition, the electronic connection terminal 33 is a flexible metal contact that provides a stable and wear-resistant electrical connection. On the splicing surface 3, at least one pair of electronic connection terminals 33 and their corresponding contact points are provided. When two or more cells are successfully spliced ​​together by the limiting member 31 and the magnetic attraction structure 32, the electronic connection terminals 33 will contact each other and establish an electrical path. This makes the spliced ​​cells electrically form a whole. Its core function is to realize "synchronous charging": the user only needs to connect the external power supply to one of the cells, and the current can be efficiently and evenly distributed to all the spliced ​​cells through the circuit formed by the electronic connection terminals 33. This not only simplifies the charging operation and ensures the consistency of the battery state of all cells, avoiding performance differences or interruption of use caused by uneven cell charge, but also optimizes charging efficiency and management.

[0034] Furthermore, the atomizing core 1 heats and atomizes the internal aerosol matrix (such as e-liquid) to produce an aerosol that the user can inhale. The mouthpiece structure 2 is fluidly connected to the atomizing core 1 and is used to guide the aerosol produced by the atomizing core 1 to flow to the user's mouth. The splicing surface 3 provides a standardized connection interface for the connection between the aerosol generating device units 10, so that different aerosol generating device units 10 can be reliably and conveniently connected and combined. This is the basis for realizing the splicing function. Users can freely choose and combine aerosol generating device units 10 according to their preferences or needs (flavor, concentration, etc.). The nozzle structure 2 is provided with an air inlet 21 spaced apart from the splicing surface 3 and an air outlet 22 connected to the air inlet 21. The specific distance between them can be adjusted according to the product size, as long as it can be ensured that the subsequent aerosol channel 4 does not fit tightly against the splicing surface. The spacing between the air inlet 21 and the splicing surface 3 provides sufficient space for the sealing structure, airflow guiding structure, etc. that may be set later, which improves the sealing reliability and reduces the risk of aerosol leakage. The connection between the air outlet 22 and the air inlet 21 ensures that the airflow entering from the air inlet 21 can continue to flow to the final user mouth. Furthermore, the central axis a of the air inlet 21 and the central axis b of the air outlet 22 are not collinear. This means that the perpendicular line from the center of the air inlet 21 to its plane and the perpendicular line from the center of the air outlet 22 to its plane are not on the same straight line in space and have a certain offset. In other words, the projections of the air inlet 21 and the air outlet 22 in the horizontal direction are deviated and do not completely coincide. By designing the air inlet 21 and the air outlet 22 of the nozzle structure 2 to be non-collinear, the aerosol channel 4 can be naturally separated from the splicing surface 3. On the one hand, this provides sufficient space for the sealing silicone and other structures to ensure the sealing performance of the device. On the other hand, it avoids the conflict between the aerosol channel 4 and other internal components, which facilitates the layout and assembly of the overall structure.

[0035] like Figure 3 As shown, this application provides an embodiment of an aerosol generating device unit 10. The aerosol generating device unit 10 is provided with an aerosol channel 4, which provides a transport path for aerosol from the atomizing core 1 to the nozzle structure 2, ensuring the efficiency and controllability of aerosol transmission. The aerosol channel 4 has an air outlet 41 that connects to the air inlet 21 of the nozzle structure 2. This means that the end of the aerosol channel 4 (or one of its connection points) is an air outlet 41. The air outlet 41 needs to be precisely connected to the air inlet 21 on the nozzle structure 2. Precise connection means that the air outlet 41 and the air inlet on the nozzle structure 2 are precisely connected together and tightly fitted to form an airtight fluid channel. This helps to ensure that no leakage occurs during the transmission of aerosol from the channel to the nozzle, and maintains the stability of internal pressure and airflow organization.

[0036] Furthermore, such as Figures 3-4As shown, the air outlet 41 and the air inlet 21 are positioned directly opposite each other, or the central axis of the air outlet 41 and the central axis of the air inlet 21 are substantially coincident. "Substantially coincident" means that minor manufacturing tolerances or design deviations are allowed, and the two axes are not required to be completely identical. However, they are considered to be coaxial in function. The design of being directly opposite each other or having substantially coincident axes makes the flow path of aerosol from the air outlet 41 to the air inlet 21 the shortest and most direct, reducing flow resistance and helping to improve aerosol transmission efficiency and the smoothness of user experience.

[0037] Furthermore, such as Figures 3-4 As shown, the aerosol channel 4 is spaced apart from the splicing surface 3. The distance from the central axis of the aerosol channel 4 to the splicing surface 3 ranges from 5.7mm to 11.7mm. Since the present invention requires the air inlet 21 of the suction nozzle structure 2 to be spaced apart from the splicing surface 3, and the end air outlet 41 of the aerosol channel 4 must be directly opposite the air inlet 21, the aerosol channel 4 must also be spaced apart from the splicing surface 3. This arrangement also facilitates the arrangement of liquid storage structure, sealing structure, fixing structure or other functional components.

[0038] Furthermore, such as Figures 3-4 As shown, the aerosol generating device unit 10 includes a storage cavity 5 for containing an aerosol matrix, which contains e-liquid and other aerosol matrices. An aerosol channel 4 passes through the storage cavity 5. In order to meet the internal structural requirements of the spliced ​​electronic cigarette, the aerosol channel 4 is offset from the central axis of the storage cavity 5 towards the splicing surface 3.

[0039] In one embodiment of this application, the aerosol generating matrix comprises a liquid of at least one aerosol forming material, such as glycerol. In some alternative examples, the aerosol generating matrix may include tobacco extract, areca nut extract, or other plant extracts, and may also include synthetic alkaloids or pharmaceutical ingredients. For example, the aerosol forming material may include a combination of nicotine salts, glycerol, propylene glycol, and cooling or flavoring agents. It has been found that aerosol forming materials improve the sensory properties of the aerosol generating matrix by facilitating the transfer of compounds (e.g., flavor compounds) from the aerosol generating material to the consumer.

[0040] In one embodiment of this application, such as Figures 1-4 As shown, the air outlet 21 expands in a trumpet shape. The trumpet shape means that the cross-sectional area of ​​the air outlet 21 gradually increases from the inside to the outside, and the shape is similar to a trumpet. The inner surface of the air outlet 21 is limited to one side approaching or ending at the splicing surface 3. The inclined sidewall forms a thickened structure in the area in contact with the splicing surface 3, which can improve the impact resistance of this area during splicing and the stability of the overall structure. The trumpet-shaped air outlet 21 can simulate the shape of a human mouth, providing a more comfortable and fitting sucking experience and reducing air leakage.

[0041] As an example, such as Figures 3-4 As shown, the nozzle structure 2 includes a wall 23 that defines the air inlet 21 and the air outlet 22. A section of the wall 23 near the air inlet 21 is inclined toward the splicing surface 3 to form a thickened structure. By increasing the structural thickness of a specific part of the nozzle structure 2, the heat generated inside can be buffered to a certain extent, so that the outer surface of the nozzle can maintain a relatively low temperature when the user uses it.

[0042] As an example, such as Figures 3-4 As shown, the longitudinal projection of the air outlet 22 partially overlaps with the longitudinal projection of the aerosol channel 4. The longitudinal projection refers to the pattern obtained by projecting the air outlet 22 and the aerosol channel 4 along the length direction of the aerosol generating device unit 10 (usually the vertical direction during use) onto a plane. The area of ​​this overlapping region is greater than half of the projected area of ​​the aerosol channel 4. In a non-collinear layout, this overlapping of projections can maintain or optimize the transmission efficiency of aerosol from the aerosol channel 4 to the air outlet 22 while keeping the air inlet 21 and the air outlet 22 non-collinear.

[0043] In one embodiment of this application, such as Figures 3-4 As shown, the inner surfaces of the outlets 22 of at least two aerosol generating device units 10 approach each other. The approaching inner surfaces may guide the airflow from the outlets 22 of the two aerosol generating device units 10, guide the airflow to merge, and prevent the airflow from separating, thereby forming a more coherent aerosol and bringing a better taste and a smoother user experience.

[0044] As an example, such as Figures 3-4 As shown, part of the inner surface of the air outlet 22 includes a straight section 221 that is basically parallel to the splicing surface 3 and a curved section 222 that is inclined toward the splicing surface 3. The straight section 221 can provide a relatively stable airflow channel, while the inclined curved section 222 actively guides the airflow toward the splicing surface 3 to converge, which can more effectively promote the mixing of aerosols.

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.
