Description

Technical Field

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

[0002] Electronic atomizers utilize a liquid aerosol generating matrix to produce aerosols for users to inhale. Some electronic atomizers employ a dual-reservoir design to achieve diverse flavor experiences. The main reservoir stores liquid aerosol generating matrices for common flavors, while the secondary reservoir stores liquid aerosol generating matrices for unique and unconventional flavors, resulting in a variety of flavor profiles. In the dual-reservoir channel design, each reservoir has an independent airflow channel. However, when the main reservoir is active while the secondary reservoir is inactive, the aerosol generated in the main reservoir channel may mix with the cold air in the secondary reservoir channel, potentially causing uneven aerosol heating, leading to a poor flavor and negatively impacting the user experience.

[0046] To address the issue of uneven aerosol heat caused by the dual-airflow channel design in dual-liquid-tank electronic atomizers, the aerosol generating device provided in this application, through the rational arrangement of the first and second atomizing components and the optimized setting of the airflow channels, enables the first atomizing channel of the first atomizing component and the second atomizing channel of the second atomizing component to form the upstream and downstream of the airflow channel. This allows the aerosols generated by the two atomizing components to mix better during the flow process, thereby improving the uneven aerosol heat distribution.

[0047] Please refer to the following: Figures 1 to 4The first embodiment of this application provides an aerosol generating device 10, including a first atomizing component 11 and a second atomizing component 12. The first atomizing component 11 has a first atomizing air channel 111, and the first atomizing component 11 is composed of a first atomizing core 112 and a first liquid storage chamber 113; the first liquid storage chamber 113 is provided with a first liquid storage cavity 1131, and the first atomizing core 112 connects the first atomizing air channel 111 and the first liquid storage cavity 1131. When a user uses the aerosol generating device 10, the aerosol generating matrix in the first liquid storage chamber 1131 is atomized by the first atomizing core 112 to generate aerosol. The aerosol enters and flows along the first atomizing airway 111 to the second atomizing airway 121. The second atomizing component 12 has a second atomizing airway 121 and is composed of a second atomizing core 122 and a second liquid storage chamber 123. The second liquid storage chamber 123 is provided with a second liquid storage cavity 1231. The second atomizing core 122 connects the second atomizing airway 121 and the second liquid storage cavity 1231. The aerosol generating matrix in the second liquid storage cavity 1231 is atomized by the second atomizing core 122, and the generated aerosol enters and flows along the second atomizing airway 121 to the user.

[0048] The first atomizing channel 111 and the second atomizing channel 121 are interconnected to form an airflow channel 13. The first atomizing channel 111 is located upstream of the airflow channel 13, and the second atomizing channel 121 is located downstream. This allows the aerosol generated in the first atomizing channel 111 to enter the airflow channel 13 first, where it mixes with the aerosol generated from the downstream second atomizing channel 121 during its flow. This ensures that the aerosols generated by different atomizing components are fully mixed as they flow along the airflow channel 13, effectively improving the problem of uneven aerosol heat distribution. The second atomizing channel 121 is closer to the nozzle of the aerosol generating device 10 than the first atomizing channel 111. The generated aerosols mix at the second atomizing channel 121, shortening the mist exit distance and helping to reduce condensate generation.

[0049] The first liquid storage chamber 113 and the second liquid storage chamber 123 can be integrated and manufactured by integral molding. The first liquid storage cavity 1131 and the second liquid storage cavity 1231 are formed inside respectively. The airflow channel 13 runs through the integrated structure and connects the first liquid storage cavity 1131 and the second liquid storage cavity 1231 through the first atomizing core 112 and the second atomizing core 122 respectively.

[0050] The first liquid storage chamber 1131 is provided with a liquid storage component 114 for adsorbing and storing the liquid aerosol generation matrix. The liquid storage component 114 is detachably designed as a first liquid storage component 1141 and a second liquid storage component 1142 that are connected to each other. The density of the first liquid storage component 1141 is greater than the density of the second liquid storage component 1142. One end of the first liquid storage component 1141 is in contact with one end of the first atomizing component 11. During use, the first liquid storage component 1141 is located at the bottom of the second liquid storage component 1142. The first liquid storage component 1141 and the second liquid storage component 1142, which have different densities, are in contact with each other. Their contact surfaces will generate a siphon effect, and the liquid aerosol generating matrix can migrate from the lower density second liquid storage component 1142 to the higher density first liquid storage component 1141. The first liquid storage component 1141 is used to cover the first atomizing core 112. When the first liquid storage component 1141 continuously consumes the liquid aerosol generating matrix, the second liquid storage component 1142 can replenish the liquid aerosol generating matrix to the first liquid storage component 1141 in a timely manner under the action of gravity and siphon, which helps to reduce the residual liquid rate.

[0051] The first atomizing component 11 also has a sealing component 115, which is made of a sealing material such as silicone and is used to form a seal at the bottom of the first liquid storage chamber 113. The sealing component 115 is provided with a microphone channel communicating with the first atomizing air passage 111 and is equipped with a microphone component 14. The second atomizing component 12 is provided with a sealing cover 124; the sealing cover 124 can be in the form of an inverted fastener and can be detachably installed on the second liquid storage chamber 123, so that the user can easily remove it and inject liquid aerosol into the second liquid storage chamber 1231 to generate a matrix.

[0052] Furthermore, the atomization methods of the first atomizing core 112 and the second atomizing core 122 can be selected from heating atomization, ultrasonic atomization, and high-pressure atomization, respectively. Different atomization methods have different characteristics and applicable scenarios. Specifically, heating atomization enables the aerosol generating matrix to rapidly heat up and atomize, producing aerosols at higher temperatures and generating a large amount of aerosols in a short time. Ultrasonic atomization causes the aerosol generating matrix to form tiny and fine droplets, resulting in aerosols with relatively lower temperatures and more uniform particle distribution. High-pressure atomization uses high pressure to propel the aerosol generating matrix into a mist, allowing for more uniform distribution of aerosols in space.

[0053] The appropriate atomization method can be selected according to actual needs, or different combinations of atomization methods can be used for the first atomizing core 112 and the second atomizing core 122 to better regulate the generation and heat distribution of aerosols and further solve the problem of uneven heat distribution of aerosols. For example, heating atomization and ultrasonic atomization can be applied to the first atomizing core 112 and the second atomizing core 122 respectively. This allows the aerosols to regulate each other's heat when mixed in the airflow channel 13 formed by the connection of the first atomizing channel 111 and the second atomizing channel 121, resulting in a more uniform heat distribution of the aerosols that finally flow to the user. This effectively solves the problem of uneven heat distribution of aerosols caused by the design of the dual liquid storage chamber and dual airflow channel 13.

[0054] Please continue to refer to the following: Figures 2 to 4 In one embodiment, a first atomizing core 112 is housed in a first atomizing air passage 111. The first atomizing core 112 includes a first fixing cylinder 1121, a first heating mesh 1122, and a first liquid guiding member 1123. The first fixing cylinder 1121 is located within the first atomizing air passage 111 and has a liquid guiding port 1124 communicating with a first liquid storage chamber 1131. The first heating mesh 1122 is housed within the first fixing cylinder 1121 and surrounds its inner wall. The first liquid guiding member 1123 is located between the inner wall of the first fixing cylinder 1121 and the first heating mesh 1122, and at least partially fills the liquid guiding port 1124, communicating with the first liquid storage chamber 1131. The aerosol generating matrix in the first liquid storage chamber 1131 is adsorbed by the first liquid guiding member 1123 through the liquid guiding port 1124. The first liquid guiding element 1123 is used to transfer the aerosol generation matrix to the first heating mesh 1122. The first heating mesh 1122 is energized and heats up to atomize the matrix. The first heating mesh 1122 is arranged around the inner wall of the first fixed cylinder 1121, which enables the generated aerosol to be distributed more evenly, ensuring uniform mixing with the aerosol generated by the second atomizing channel 121 and helping to improve the uneven heat distribution of the aerosol.

[0055] Please continue reading. Figure 2In one embodiment, the second atomizing core 122 is housed in the second liquid storage chamber 1231 and has a liquid inlet 1221 and an air outlet 1222. The liquid inlet 1221 communicates with the second liquid storage chamber 1231, and the air outlet 1222 communicates with the second atomizing air passage 121, allowing the aerosol generating matrix in the second liquid storage chamber 1231 to smoothly enter the second atomizing core 122 through the liquid inlet 1221. After being atomized in the second atomizing core 122, it is discharged from the air outlet 1222 into the second atomizing air passage 121. Since the second atomizing core 122 is housed in the second liquid storage chamber 1231, the second atomizing core 122 directly obtains the aerosol generating matrix in the second liquid storage chamber 1231, improving atomization efficiency. At the same time, it also facilitates the aerosol generated by atomization to enter the second atomizing air passage 121 and mix with the aerosol in the first atomizing air passage 111, further promoting the uniform heat distribution of the aerosol.

[0056] Please continue to refer to the following: Figures 2 to 4Furthermore, the second atomizing core 122 is composed of a first support 1223, a second support 1224, a liquid suction element 1225, and a heating mesh 1226. The first support 1223 is provided with a liquid inlet 1227 that communicates with the second liquid storage chamber 1231; the liquid inlet 1227 can be in the form of a mesh to form a liquid surface tension at the mesh, which has a certain reaction force, which cancels out the pressure of the liquid aerosol generation matrix in the second liquid storage chamber 1231, thereby reducing the risk of leakage. The second support 1224 is connected to the first support 1223 to form a receiving cavity 1228. The second support 1224 has an outlet 1229 that connects to the second atomizing air channel 121. Specifically, the second liquid storage chamber 123 can form an open second liquid storage cavity 1231, which stores a liquid aerosol generating matrix. The first support 1223 and the second support 1224 are embedded in the opening, and a gap is formed between the first support 1223 and the second support 1224 to form the receiving cavity 1228. The liquid suction member 1225 is received in the receiving cavity 1228 and connected to the liquid inlet 1227. The liquid suction member 1225 draws the aerosol generating matrix from the second liquid storage cavity 1231 through the liquid inlet 1227. The heating mesh 1226 is located between the liquid suction member 1225 and the outlet 1229, and is laid flat on the side of the liquid suction member 1225 away from the liquid inlet 1227. When the aerosol generating device 10 is working, the matrix in the second liquid storage chamber 1231 is absorbed by the liquid suction element 1225 through the liquid inlet 1227. The liquid suction element 1225 transfers the aerosol generating matrix to the heating mesh 1226. The heating mesh 1226 is energized and heats up, causing the aerosol generating matrix to atomize. The atomized aerosol is discharged from the air outlet 1229 to the second atomizing air channel 121, so that the absorption, atomization and discharge of the aerosol generating matrix are carried out in an orderly manner, which can stably produce aerosol. Furthermore, because the heating mesh 1226 is laid flat, the aerosol can diffuse more evenly into the second atomizing air channel 121 when discharged, which is beneficial to fully mix with the aerosol in the first atomizing air channel 111 and improve the problem of uneven heat distribution of the aerosol.

[0057] In another embodiment, the second atomizing core 122 is housed in the second atomizing air passage 121. The second atomizing core 122 includes a second fixed cylinder, a second heating mesh, and a second liquid guiding component. The second fixed cylinder is located within the second atomizing air passage 121 and has a liquid supply port communicating with the second liquid storage chamber 1231. The second heating mesh is housed within the second fixed cylinder and surrounds its inner wall. The second liquid guiding component is located between the inner wall of the second fixed cylinder and the second heating mesh, and at least partially fills the liquid supply port, communicating with the second liquid storage chamber 1231. The aerosol generating matrix in the second liquid storage chamber 1231 is adsorbed by the second liquid guiding component through the liquid supply port. The second liquid guiding component transfers the aerosol generating matrix to the second heating mesh, and the second heating mesh is energized to generate heat, causing the aerosol generating matrix to atomize. The second atomizing core 122 is installed in the second atomizing air channel 121 to generate aerosol evenly. The surrounding second heating mesh helps the aerosol to be evenly distributed in the second atomizing air channel 121, further promoting the mixing with the aerosol in the first atomizing air channel 111, thereby improving the problem of uneven heat distribution of the aerosol.

[0058] In one embodiment, the second atomizing component 12 is detachably connected to the first atomizing component 11, facilitating maintenance and component replacement. The second atomizing component 12 and the first atomizing component 11 are stacked, resulting in a compact spatial arrangement and also facilitating smooth communication of the airflow channel 13. This allows the aerosol generated by the first atomizing airway 111 to flow smoothly to the second atomizing airway 121, enabling better mixing of aerosols generated by different atomizing components and effectively improving the problem of uneven aerosol heat distribution.

[0059] Furthermore, the second atomizing component 12 is detachably connected to the first atomizing component 11; the first atomizing component 11 is L-shaped and has a receiving step; the second atomizing component 12 is snapped onto the receiving step. The snap-fit ​​connection between the second atomizing component 12 and the first atomizing component 11 not only facilitates disassembly and installation but also ensures the connection stability between the two atomizing components. The L-shaped first atomizing component 11 forms a receiving step, allowing the second atomizing component 12 to accurately align with the first atomizing component 11, ensuring the connectivity of the airflow channel 13; simultaneously, it also helps adjust the relative position and angle between the two atomizing components, thereby optimizing the aerosol flow path and mixing effect, and further improving the uneven heat distribution of the aerosol.

[0060] In another embodiment, the aerosol generating device 10 further includes a third atomizing component (not shown); the third atomizing component has a third atomizing air passage, and the third atomizing component consists of a third atomizing core and a third liquid storage chamber; the third atomizing core connects the third atomizing air passage and the third liquid storage chamber; the third atomizing air passage connects to the end of the second atomizing air passage 121 away from the first atomizing air passage 111. By adding the third atomizing component, the source and types of aerosols can be further enriched. Aerosols generated by different atomizing components are mixed sequentially in the airflow channel 13, which can make the heat distribution of the aerosols more uniform. For example, the first atomizing component 11, the second atomizing component 12, and the third atomizing component can adopt different atomization methods or use aerosol generating matrices with different flavors. By reasonably adjusting the operating parameters of each atomizing component, aerosols with different heat and flavor types can be fully mixed during the flow process, thereby effectively solving the problem of uneven heat distribution of aerosols.

[0061] This application does not limit the number of atomizing components in the aerosol generating device 10. In addition to using the first atomizing component 11, the second atomizing component 12 and the third atomizing component, a fourth atomizing component, a fifth atomizing component or more atomizing components can be added. All of these help to uniformly mix the aerosols generated by different atomizing components and improve the uniformity of heat distribution of the aerosol inhaled by the user.

[0062] Please continue to refer to the following: Figures 1 to 4 In one embodiment, the aerosol generating device 10 is further equipped with a control component 15 and a battery. The control component 15 is electrically connected to the first atomizing core 112 and the second atomizing core 122, respectively. The battery is electrically connected to the control component 15 and supplies power to the first atomizing core 112 and the second atomizing core 122 through the control component 15. By setting the control component 15, the operating parameters of the first atomizing core 112 and the second atomizing core 122 can be precisely controlled, such as adjusting the heating power and atomization frequency. By adjusting the operating parameters of the two atomizing cores, the amount of aerosol generated by different atomizing components can be controlled according to actual needs, thereby achieving precise adjustment of the aerosol mixing effect. In this embodiment, the first atomizing core 112 is electrically connected to the circuit board in the control assembly 15 via a first lead 116, and the second atomizing core 122 is electrically connected to the circuit board via a second lead 125. The second lead 125 extends from the second liquid storage chamber 123 along the outer surfaces of the first and second liquid storage chambers 113 and 123 to connect with the circuit board. The outer surfaces of the first and second liquid storage chambers 113 and 123 are provided with slots to accommodate the second lead 125, ensuring that the second lead 125 is tightly fitted to the surfaces of the first and second liquid storage chambers 113 and 123 to prevent it from being broken during assembly. The second atomizing assembly 12 also includes an electrode 126, and the heating mesh 1226 is electrically connected to the second lead 125 via the electrode 126.

[0063] This application provides an aerosol generating device. By rationally arranging the first atomizing component and the second atomizing component, and optimizing the airflow channel, the first atomizing channel of the first atomizing component and the second atomizing channel of the second atomizing component form the upstream and downstream of the airflow channel. This allows the aerosols generated by the two atomizing components to mix better during the flow process, thereby improving the uneven heat distribution of the aerosols.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
