[0002] An aerosol generating device is a device or apparatus that uses specific technical means to convert liquids, solids, or mixtures thereof into an aerosol state. Its working principle typically involves using methods such as heating, atomization, and ultrasound to disperse substances into tiny particles that are suspended in a gas, thus forming an aerosol.

[0003] In related technologies, aerosol generating devices have an aerosol generating channel. To enable the measurement of the number of times a user inhales, a microphone is usually installed in the aerosol generating channel.

[0004] However, since aerosols are present in the aerosol generation channel for a long time, the microphone is exposed to this environment for a long time and is easily damaged by the corrosion of aerosols. Once the microphone is damaged, it will directly cause the metering function of the aerosol generation device to fail, and may even affect the normal operation of the entire device.

This facilitates precise counting of suction ports, providing users with more accurate usage data. Attached Figure Description

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] As described in the background section, an aerosol generating device is a device or apparatus that uses specific technical means to convert liquids, solids, or mixtures thereof into an aerosol state. Its working principle typically involves using methods such as heating, atomization, or ultrasound to disperse substances into tiny particles that are suspended in a gas, forming an aerosol. In related technologies, aerosol generating devices have an aerosol generating channel, and a microphone is usually installed within this channel to measure the number of puffs taken by the user. However, because aerosols are present in the aerosol generating channel for extended periods, the microphone is constantly exposed to this environment and is highly susceptible to corrosion and damage. Damage to the microphone directly leads to the failure of the puff-counting function of the aerosol generating device, and may even affect the normal operation of the entire device.

[0036] Reference Figures 1 to 7 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an aerosol generating device, which includes an aerosol generating component 100, a sound detection component 200, and a controller 300. The aerosol generating component 100 has an aerosol generating channel 111. The sound detection component 200 is disposed outside the aerosol generating channel 111 and is used to detect the sound decibel level generated when the suction airflow flows through the aerosol generating channel 111. The controller is configured to control the aerosol generating device to record one aerosol suction when the sound decibel level reaches a preset value.

[0037] In this embodiment, the sound detection element 200 can be a microphone, such as a dynamic microphone, condenser microphone, electret microphone, or MEMS (Micro-Electro-Mechanical Systems) microphone. The sound detection element 200 is fixedly mounted on the aerosol generator 100, with a preset value of 50 decibels. It is understood that the preset value can also be other decibel values, depending on actual needs. The controller 300 is located outside the aerosol generation channel 111 and is electrically connected to the aerosol generator 100 and the sound detection element 200, used to record the number of aspirations.

[0038] The sound detector 200 detects the decibel level of the sound (hereinafter referred to as the suction sound) generated when the suction airflow passes through the aerosol generation channel 111. When the suction sound decibel level reaches a preset value, the controller 300 records one suction cycle. This recording method can accurately count the number of times the user uses the aerosol generation device to suction aerosol. Simultaneously, placing the sound detector 200 outside the aerosol generation channel 111 avoids direct exposure of the sound detector 200 to the aerosol environment within the aerosol generation channel 111, effectively preventing corrosion and damage to the sound detector 200 by aerosols, reducing the risk of damage, and enabling the sound detector 200 to stably and accurately detect the decibel level of the suction sound. This ensures the stability and reliability of the suction port counting function, facilitating accurate counting of suction ports and providing users with more accurate usage data.

[0039] Reference Figures 1 to 7 In one embodiment, the aerosol generation channel 111 has a cavity 121 for receiving the aerosol generation matrix 500 and an insertion port 122 for inserting the aerosol generation matrix 500 into the cavity 121.

[0040] In this embodiment, the aerosol generating device is an HNB device. HNB stands for Heat Not Burning Tobacco Products, and its Chinese name is Heated Non-combustible Aerosol Generating Matrix 500. The aerosol generating matrix 500 is a cigarette stick or cartridge. The aerosol generating matrix 500 is inserted into the cavity 121 through the insertion port 122 and converted into an aerosol within the cavity 121. It is understood that the aerosol generating device can also be an electronic atomizing device.

[0041] Compared to traditional tobacco combustion, HNB (Heated Tobacco Bundle) devices generate aerosols by heating rather than burning the aerosol-generating matrix 500. This significantly reduces the production of harmful chemicals such as tar and carbon monoxide generated during combustion, thus minimizing health risks for users. Furthermore, because they do not produce open flames or large amounts of smoke, HNB devices generate relatively less secondhand aerosol, and the content of harmful substances in this aerosol is also lower. This reduces the impact on the surrounding environment and others, and mitigates the harm of secondhand smoke.

[0042] Reference Figures 2 to 7 In one embodiment, the aerosol generating device 100 includes an aerosol generating body 110 and a heating tube 120. An aerosol generating channel 111 is disposed in the aerosol generating body 110, and a sound detection device 200 is disposed on the outer surface of the aerosol generating body 110. The heating tube 120 is disposed in the aerosol generating channel 111, the internal space of the heating tube 120 is formed as a cavity 121, and the tube opening of the heating tube 120 is formed as an insertion port 122.

[0043] In this embodiment, the aerosol generating body 110 is cylindrical in shape. It is understood that the aerosol generating body 110 can also have other shapes, depending on actual needs, and is not limited here. The aerosol generating channel 111 is a through hole arranged along the axial direction of the aerosol generating body 110, and is coaxially arranged with the aerosol generating body 110. The sound detection element 200 is fixedly installed on the outer surface of the aerosol generating body 110. The heating tube 120 is fixedly installed inside the aerosol generating channel 111 and coaxially arranged with the aerosol generating channel 111, and is used to heat the aerosol generating matrix 500.

[0044] The sound detection element 200 is disposed on the outer surface of the aerosol generating body 110, away from the heating area of ​​the heating tube 120, thus avoiding the influence of high temperature and ensuring the stability and accuracy of its performance. This allows it to reliably detect the decibel level of the suction sound within the aerosol generating channel 111. Simultaneously, the aerosol generating channel 111 is disposed within the aerosol generating body 110, the heating tube 120 is located within the aerosol generating channel 111, and the sound detection element 200 is disposed on the outer surface of the aerosol generating body 110. This arrangement makes the entire aerosol generating device 100 compact in structure, with clear cooperative relationships between components. This facilitates manufacturing and assembly, promotes overall structural stability, and makes it convenient for users to hold and operate the aerosol generating device.

[0045] Reference Figures 2 to 7 In one embodiment, the aerosol generation channel 111 has a first opening 1111 and a second opening 1112 disposed opposite to each other along the length direction of the aerosol generation body 110; the aerosol generation component 100 further includes a limiting ring 130 and a mounting base 140. The limiting ring 130 is disposed on the aerosol generation body 110 and blocks the first opening 1111. The limiting ring 130 has an annular hole 131 for the aerosol generation matrix 500 to pass through or be withdrawn from the aerosol generation channel 111. The annular hole 131 communicates with the insertion port 122; the mounting base 140 is disposed on the aerosol generation component 100 and blocks the second opening 1112. The heating tube 120 is disposed on the mounting base 140; the sound detection component 200 is disposed on the outer surface of the aerosol generation body 110 corresponding to the limiting ring 130 and / or the outer surface of the aerosol generation body 110 corresponding to the mounting base 140.

[0046] In this embodiment, a limiting ring 130 is disposed within the aerosol generation channel 111. The limiting ring 130 and the aerosol generation body 110 are integrally formed and coaxially disposed with the aerosol generation body 110. A mounting base 140 is fixedly mounted on the aerosol generation body 110 and completely blocks the second opening 1112. A portion of the structure of the mounting base 140 is inserted into the aerosol generation channel 111 and protrudes towards the first opening 1111. A heating tube 120 is fixedly mounted on the mounting base 140.

[0047] On the one hand, the design of the annular hole 131 on the limiting ring 130 allows the aerosol generating matrix 500 to be easily inserted into or removed from the aerosol generating channel 111; users can easily replace the aerosol generating matrix 500, improving ease of use. Simultaneously, the limiting ring 130, by sealing the first opening 1111, can limit and position the aerosol generating matrix 500, ensuring it is in a suitable position within the aerosol generating channel 111, guaranteeing uniform heating by the heating tube 120, thereby stably generating aerosols.

[0048] On the other hand, the mounting base 140, by sealing the second opening 1112 and installing the heating tube 120, helps protect the heating tube 120 and other internal structures of the aerosol generator 100, reducing interference and damage from external factors. It also allows heat to be better concentrated within the aerosol generation channel 111, improving heating efficiency. Simultaneously, the limiting ring 130 and the mounting base 140, by sealing the first opening 1111 and the second opening 1112 of the aerosol generation channel 111 respectively, together with the aerosol generator body 110, form a relatively closed and stable structure. This helps improve the stability and durability of the entire aerosol generator 100, reducing the possibility of performance being affected by component loosening or displacement during use.

[0049] On the other hand, the sound detection element 200 is set on the outer surface corresponding to the limiting ring 130 and / or the mounting base 140, which can more accurately detect the decibel level of the suction sound in the aerosol generation channel 111. Because these two positions are closer to the aerosol generation area, the sound propagation path is shorter, which reduces sound attenuation and interference from external environmental noise, and improves the accuracy and reliability of sound detection.

[0050] Reference Figures 3 to 7 In one embodiment, the sound detection element 200 is disposed on the outer surface of the aerosol generating body 110 corresponding to the limiting ring 130.

[0051] In this embodiment, the sound detection element 200 is fixedly installed on the outer surface of the aerosol generating body 110 corresponding to the limiting ring 130. It is understood that the sound detection element 200 can also be fixedly installed on the outer surface of the aerosol generating body 110 corresponding to the mounting base 140; the number of sound detection elements 200 can be two, and they are respectively fixedly installed on the outer surface of the aerosol generating body 110 corresponding to the limiting ring 130 and the outer surface of the aerosol generating body 110 corresponding to the mounting base 140.

[0052] The limiting ring 130 is located near the insertion end of the aerosol generating matrix 500. When the user inhales, the sound generated travels a relatively short path from the aerosol generating channel 111 to this location and is less affected by interference from other components. The sound detection component 200 can receive the inhalation sound more accurately, effectively improving the accuracy of detecting the decibel level of the inhalation sound and helping to more accurately judge the user's inhalation behavior.

[0053] Meanwhile, this position is far from the mounting base 140 where the heating tube 120 is located, which can effectively prevent the heat generated by the heating tube 120 from affecting the sound detection element 200, prevent the performance of the sound detection element 200 from deteriorating or malfunctioning due to high temperature, and ensure that the sound detection element 200 can work stably and reliably.

[0054] Reference Figures 4 to 8 In one embodiment, the mounting base 140 has a mounting groove 141 on its surface near the first opening 1111, and the heating tube 120 is disposed in the mounting groove 141 and communicates with the mounting groove 141.

[0055] In this embodiment, the mounting groove 141 is coaxially arranged with the aerosol generation channel 111, and part of the structure of the heating tube 120 is fixedly inserted into the mounting groove 141.

[0056] The mounting slot 141 provides a fixed mounting position for the heating tube 120, which can prevent the heating tube 120 from shifting or shaking during use and reduce the risk of damage to the heating tube 120 due to collision or friction.

[0057] Meanwhile, the mounting groove 141 can wrap the heating tube 120 to a certain extent, reduce the loss of heat to the surrounding environment, and make the heat more concentrated to be transferred to the aerosol generating matrix 500, which helps to improve energy utilization, save electricity to a certain extent, and also prevent surrounding components from being damaged or aged due to heat.

[0058] Reference Figures 4 to 8 In one embodiment, the bottom of the mounting groove 141 is provided with a connecting hole 142 that allows the mounting groove 141 to communicate with the external environment.

[0059] In this embodiment, the connecting hole 142 penetrates the bottom of the mounting groove 141, and there are multiple connecting holes 142 arranged at intervals. The connecting holes 142 enable the mounting groove 141 to communicate with the external environment, thereby enabling the aerosol generation channel 111 to communicate with the external environment, ensuring that the aerosol generation matrix 500 is successfully converted into aerosol.

[0060] Reference Figures 2 to 7 In one embodiment, the aerosol generating body 110 is a high-temperature resistant plastic part. In this embodiment, the aerosol generating body 110 is made of a high-temperature resistant plastic material. It is understood that the aerosol generating body 110 may also be made of other high-temperature resistant materials, such as metal materials, ceramic materials, or composite materials.

[0061] The aerosol generating body 110 is designed to withstand the high temperatures generated by the heating tube 120 and is not prone to deformation, melting, or the generation of harmful substances due to heat, thus ensuring the structural integrity and performance stability of the aerosol generating device under normal operating temperature.

[0062] Meanwhile, compared to metal materials, plastic parts are lighter, making the entire aerosol generating device easier to carry and operate, improving user convenience. In particular, for handheld or portable aerosol generating devices, reducing weight can increase user comfort.

[0063] Furthermore, the production cost of high-temperature resistant plastics is generally lower than that of some high-performance metal or ceramic materials, which helps reduce the manufacturing cost of aerosol generating devices, thus giving them better price competitiveness in the market and facilitating product promotion and widespread adoption. Moreover, plastics have excellent insulation properties, effectively preventing current leakage from the heating element 120, avoiding the risk of electric shock to users, and improving product safety; they also reduce electromagnetic interference, ensuring the normal operation of electronic components in the aerosol generating device, such as the sound detection element 200.

[0064] Reference Figures 2 to 7 as well as Figure 9 In one embodiment, the heating element 120 is electrically connected to the controller 300. (Suction)

[0065] Through electrical connection, the controller 300 can coordinate the operation between the sound detection element 200 and the aerosol generator 100. By stopping the count or detecting the suction action, it can precisely control the working state of the heating tube 120 in the aerosol generator 100 to ensure a good suction taste and more stable operation of the entire device. Specifically, during use, the controller 300 can automatically adjust the working parameters of the heating tube 120 according to the signal fed back by the sound detection element 200 to adapt to different environmental conditions and differences in the aerosol generating matrix 500, maintain the consistency and stability of aerosol generation, and improve the overall quality of the product and user satisfaction.

[0066] Reference Figure 1 and Figure 2 In one embodiment, the aerosol generating device further includes a housing 400, and the aerosol generating component 100 and the sound detection component 200 are both disposed inside the housing 400.

[0067] In this embodiment, the aerosol generator 100, the sound detector 200, and the controller 300 are all fixedly installed inside the housing 400.

[0068] The housing 400 not only provides physical protection for the aerosol generator 100 and the sound detector 200, preventing them from being damaged by external impacts or collisions, but also effectively blocks dust and moisture from entering the components, preventing dust accumulation or moisture intrusion from affecting the performance of the aerosol generator 100 and the sound detector 200.

[0069] Meanwhile, the outer casing 400 can also block some of the noise generated by the aerosol generator 100 during operation, as well as external environmental noise, reducing interference to the sound detection unit 200 and improving its detection accuracy. Furthermore, for users, it also reduces noise interference during use, enhancing the user experience.

[0070] In addition, the housing 400 provides a fixed mounting space for the aerosol generator 100 and the sound detector 200, which facilitates the integration of the various components into a compact whole, which is conducive to the large-scale production of the product, improves production efficiency, and reduces production costs.

[0071] Reference Figures 3 to 7 as well as Figure 9 In one embodiment, the sound detection element 200 is a decibel sensor. The decibel sensor can accurately measure the intensity of sound, i.e., the decibel value; this allows it to accurately sense different intensities of sound generated when the user inhales the aerosol generating device, whether it be a slight inhalation sound or a stronger inhalation sound, providing a precise data basis for subsequent control and feedback.

[0072] Meanwhile, decibel sensors typically have a fast response characteristic, enabling them to react to changes in sound in a very short time. When a user begins to inhale, the sensor can quickly detect the presence of sound and transmit the signal to the controller 300, causing the aerosol generator 100 to promptly initiate heating and other operations. When the user stops inhaling, the sensor can also quickly sense the disappearance of sound and notify the controller 300 to make corresponding adjustments, such as stopping heating or entering standby mode, thereby achieving efficient and timely control.

[0073] In addition, the decibel sensor maintains good stability and reliability under various environmental conditions; it is not easily affected by external factors, such as changes in environmental factors like temperature and humidity, which have little impact on its detection accuracy. It can work continuously and stably in different usage scenarios and environments, ensuring the stable performance of the aerosol generation device and reducing malfunctions or abnormalities caused by inaccurate sound detection.

[0074] Reference Figures 3 to 7 In one embodiment, the sound detection element 200 is fixedly mounted on the outer surface of the aerosol generator 100 by adhesive bonding. It is understood that the sound detection element 200 can also be fixedly mounted on the outer surface of the aerosol generator 100 by screw connection, snap-fit, plug-in connection, or other connection methods.

[0075] Adhesive bonding is a relatively simple installation method that does not require complicated tools and processes. During the production process, workers only need to apply glue to the outer surface of the aerosol generator 100, then accurately place the sound detection unit 200 in the predetermined position, press it slightly, and wait for the glue to cure to complete the installation. This effectively improves production efficiency and reduces installation costs.

[0076] Meanwhile, high-quality adhesive provides strong bonding force, ensuring that the sound detection component 200 and the outer surface of the aerosol generator 100 are tightly bonded together. This prevents displacement or detachment due to vibration, shaking, or minor collisions during daily use, ensuring that the sound detection component 200 maintains a stable installation state during long-term use and thus guaranteeing the reliability of its detection performance.

[0077] Furthermore, by using adhesive bonding, the sound detection element 200 is in direct contact with the outer surface of the aerosol generating element 100, which enables better reception and transmission of sound signals generated during aerosol generation. The adhesive can fill the tiny gaps between the sound detection element 200 and the aerosol generating element 100, reducing energy loss and distortion during sound propagation, allowing the sound detection element 200 to more accurately sense changes in sound and improving detection accuracy and sensitivity.

[0078] In summary, the aerosol generating device provided in this embodiment has at least the following beneficial technical effects: The sound detector 200 detects the decibel level of the suction sound within the aerosol generating channel 111. When the sound decibel level reaches a preset value, the controller 300 records one suction cycle. This recording method can accurately count the number of times the user uses the aerosol generating device to draw aerosols. Simultaneously, placing the sound detector 200 outside the aerosol generating channel 111 avoids direct exposure of the sound detector 200 to the aerosol environment within the aerosol generating channel 111, effectively preventing corrosion and damage to the sound detector 200 by aerosols, reducing the risk of damage, and enabling the sound detector 200 to stably and accurately detect the decibel level of the suction sound. This ensures the stability and reliability of the suction port counting function, facilitating accurate counting of suction ports and providing users with more accurate usage data.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
