Description

Technical Field

[0001] This application belongs to the technical field of aerosol generating equipment, and more specifically, relates to an aerosol generating device. Background Technology

[0002] With the continuous improvement of living standards, aerosol generating equipment, especially portable aerosol generating equipment, has rapidly entered thousands of households due to its convenience and practicality, and has gained widespread popularity in the market, with its usage scale continuing to expand.

[0003] However, existing aerosol generators still have technical shortcomings in their function of providing users with inhaled air during actual use, which urgently need to be addressed. These shortcomings are mainly reflected in the following two aspects: On the one hand, in the aerosol delivery path, when the high-temperature aerosol gas generated by heating flows into the mouthpiece airway at room temperature, due to the significant temperature difference between the inner wall of the airway and the aerosol, some components of the aerosol will liquefy on the inner wall of the airway, forming condensate, according to the physical properties of condensation. With increased use, the condensate will gradually accumulate in the airway, which will not only cause phenomena such as "oil splattering" and "leakage" during inhalation, but also change the taste and concentration of the aerosol, seriously affecting the user experience.

[0004] On the other hand, as the part of the aerosol generator that comes into direct contact with the user's mouth, the nozzle is prone to accumulating dust, saliva residue, and other contaminants on its surface and inside during daily use due to frequent suction operations and contact with the external environment when the device is stored externally. This leads to the growth of a large number of bacteria. In actual use, users often lack the awareness and habit of actively cleaning the nozzle. After long-term use, the hygiene of the nozzle deteriorates, which may pose a potential threat to the user's oral health and become a major problem affecting the safety of aerosol generator use. Utility Model Content The purpose of this application is to provide an aerosol generating device to solve the problem of condensation easily generated at the nozzle of the aerosol generating device in the prior art.

[0005] To achieve the above objectives, according to one aspect of this application, an aerosol generating device is provided. The aerosol generating device includes: an aerosol generating main body and a nozzle part disposed on the aerosol generating main body. The nozzle part includes a nozzle body and an outlet chamber disposed therein, wherein the outlet chamber forms an outlet at the end of the nozzle body away from the aerosol generating main body; and a heating assembly including a heating part disposed outside the side wall of the nozzle body and capable of transferring heat to the gas in the outlet chamber through the side wall of the nozzle body. Optionally, the heating element is attached to the outside of the side wall of the nozzle body. Optionally, the heating element includes a heating plate, which includes a main structure and a fixing structure disposed on the side of the main structure. The fixing structure is used to connect with the side wall of the nozzle. Optionally, the fixing structure extends along the outer surface of the sidewall of the nozzle body and is attached to the outside of the sidewall of the nozzle body. Optionally, the side wall of the nozzle body is provided with a first notch, which is connected to the air outlet, and the main structure includes a second notch that corresponds to the position of the first notch. Optionally, the aerosol generator further includes a housing, which is fitted over the outside of the aerosol generator body and has a nozzle protrusion fitted over the nozzle body. A nozzle opening is provided at the position of the nozzle protrusion corresponding to the air outlet, and a heating component is disposed between the nozzle body and the nozzle protrusion. Optionally, the aerosol generating main body includes a power supply component and a control component electrically connected to the power supply component, and the heating component also includes a conductive part, the two ends of which are electrically connected to the control component and the heating part respectively, so as to supply power to the heating part. Optionally, the aerosol generator further includes a button assembly, which includes a button body and a button control unit electrically connected to the control assembly.

[0006] Optionally, a positioning groove is provided on the side of the aerosol generating body, and the conductive part includes an FPC lead wire. The two ends of the FPC lead wire are electrically connected to the heating part and the power supply component, respectively, and the FPC lead wire is embedded in the positioning groove.

[0007] Optionally, the fixing structure is engaged with the side wall of the nozzle body. The beneficial effects of the aerosol generating device provided in this application are as follows: Compared with the prior art, heat can be transferred to the gas in the outlet chamber through the side wall of the nozzle body, maintaining a certain temperature inside the outlet chamber. When the high-temperature aerosol gas flow enters the outlet chamber, the temperature difference between the outlet chamber wall and the gas inside and the aerosol temperature is significantly reduced, which greatly reduces the probability of aerosol liquefaction due to a sudden drop in temperature, and reduces the formation and accumulation of condensate on the outlet chamber wall. This not only avoids phenomena such as "splattering" and "leakage" during suction, but also maintains the original taste and concentration of the aerosol, significantly improving the user's suction experience.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0015] As described in the background section, existing aerosol generating devices still have technical defects in their function of providing users with inhaled air during actual use, which urgently need to be addressed. These defects are mainly reflected in the following two aspects: On the one hand, in the aerosol transmission path, when the high-temperature aerosol gas generated by heating flows into the mouthpiece airway at room temperature, due to the significant temperature difference between the inner wall of the airway and the aerosol, some components of the aerosol will liquefy on the inner wall of the airway, forming condensate, according to the physical properties of condensation. With increased use, condensate will gradually accumulate in the airway, not only causing phenomena such as "oil splattering" and "leakage" during suction, but also changing the taste and concentration of the aerosol, seriously affecting the user experience. On the other hand, as the part of the aerosol generator that comes into direct contact with the user's mouth, the mouthpiece is easily contaminated with dust, saliva residue, and other dirt on its surface and inside due to frequent suction operations and contact with the external environment when the device is stored externally, leading to the growth of a large number of bacteria. In actual use, users often lack the awareness and habit of actively cleaning the mouthpiece. After long-term use, the hygiene of the mouthpiece deteriorates, which may pose a potential threat to the user's oral health, becoming a major problem affecting the safety of using aerosol generators. To solve the above problem, see Figures 1 to 5 As shown, the aerosol generating device in this embodiment includes an aerosol generating main body 10, a nozzle portion disposed on the aerosol generating main body 10, and a heating assembly 20. The nozzle portion includes a nozzle body 111 and an outlet chamber disposed within the nozzle body 111. The outlet chamber forms an outlet 112 at the end of the nozzle body 111 away from the aerosol generating main body. The heating assembly 20 includes a heating part 21, which is disposed outside the side wall of the nozzle body 111 and can transfer heat to the gas in the outlet chamber through the side wall of the nozzle body 111. The aerosol generating device is a device capable of converting a specific medium into an aerosol form through a specific method (such as heating, ultrasound, etc.) and making it available to the user. The aerosol generating main body 10 is the core component of the aerosol generating device, mainly responsible for the aerosol generation function. It usually integrates atomization medium storage, atomization core components (such as heating elements, atomization chambers, etc.) and related control circuits, providing the necessary material basis and energy support for aerosol generation.

[0016] It should be noted that the mouthpiece is the component in the aerosol generator that comes into direct contact with the user's mouth. As the channel through which aerosol is delivered to the user's mouth, its structure directly affects the suction experience and hygiene. It is typically connected to the aerosol generator body 10. The mouthpiece body 111 is the main structure 2111 of the mouthpiece, forming its external framework and basic support. Its interior forms a channel for aerosol flow, and the material is usually food-grade silicone, plastic, or other materials that meet hygiene requirements and have a certain degree of heat resistance. The air outlet chamber is a hollow structure located inside the mouthpiece body 111. It is the key channel for aerosol transmission from the aerosol generator body 10 to the air outlet 112. The air outlet 112 is located at the end of the mouthpiece body 111 furthest from the aerosol generator body 10, and is the exit point for the aerosol to leave the mouthpiece and enter the user's mouth.

[0017] It should be noted that the heating component 20 is a functional component used to provide heat. It converts energy into heat energy in the form of electricity and transfers the heat to a specific part to achieve the purpose of heating and raising the temperature. In this application, it is mainly used to regulate the heating of the nozzle. The heating part 21 is the core heat-generating component of the heating component 20, which can directly generate heat. Its position (outside the side wall of the nozzle body 111) ensures that heat can be effectively transferred to the nozzle body 111 and the air outlet chamber. In the embodiment of this application, the heating part 21 is attached to the outside of the side wall of the nozzle body 111.

[0018] The heating element 21 of the heating assembly 20 of the aerosol generator of this application is disposed on the outside of the side wall of the nozzle body 111. It can transfer heat to the gas inside the outlet chamber through the side wall of the nozzle body 111, maintaining a certain temperature inside the outlet chamber. When the high-temperature aerosol gas flow enters the outlet chamber, the temperature difference between the inner wall of the outlet chamber and the gas inside and the aerosol temperature is significantly reduced. This greatly reduces the probability of aerosol liquefaction due to a sudden temperature drop, and reduces the formation and accumulation of condensate on the inner wall of the outlet chamber. This not only avoids phenomena such as "splattering" and "leakage" during suction, but also maintains the original taste and concentration of the aerosol, significantly improving the user's suction experience. In one embodiment, to address hygiene issues at the mouthpiece, the heat transferred by the heating unit 21 maintains the mouthpiece body 111 and the air outlet chamber at a relatively high temperature. This sustained temperature increase inhibits bacterial growth on the mouthpiece surface and inside the air outlet chamber, and may even kill some heat-sensitive bacteria. Even when the user lacks a proactive cleaning habit, this heating structure reduces the proliferation of bacteria at the mouthpiece, improves mouthpiece hygiene, lowers the potential threat to the user's oral health caused by mouthpiece hygiene problems, and enhances the safety of the aerosol generator. The aerosol generator of this application places the heating element 21 of the heating assembly 20 on the outside of the side wall of the nozzle body 111, rather than inside the air outlet chamber, effectively avoiding direct contact between the heating element 21 and the aerosol in the air outlet chamber. The aerosol in the air outlet chamber typically contains various components generated by the heating of the atomizing medium, some of which may be corrosive or sticky. If the heating element 21 is placed inside the air outlet chamber, long-term contact with the aerosol may cause the corrosive components in the aerosol to gradually erode the surface material of the heating element 21, affecting its structural integrity and heating performance; simultaneously, sticky components may adhere to the surface of the heating element 21, forming a dirt layer that hinders heat transfer and reduces heating efficiency. By placing the heating element 21 on the outside of the side wall of the nozzle body 111, direct contact between the heating element 21 and the aerosol can be spatially isolated, reducing chemical corrosion and physical contamination of the heating element 21 by the aerosol, thereby protecting its structure and performance and extending its service life. Secondly, it reduces the maintenance difficulty of the heating element 21. When the heating element 21 is located inside the air outlet chamber, cleaning the heating element 21 requires going deep into the air outlet chamber, which is inconvenient and can easily damage the air outlet chamber. However, the heating element 21 is located on the outside of the side wall of the nozzle body 111, which makes it easy for users or maintenance personnel to directly inspect, clean or replace it without complicated disassembly steps, reducing maintenance costs and time, and ensuring that the heating component 20 works stably for a long time. The heating element 21 in this embodiment includes a heating plate, which comprises a main structure 2111 and a fixing structure 2112 disposed on the side of the main structure 2111. The fixing structure 2112 is used to connect with the side wall of the mouthpiece. From the perspective of heat transfer, the main structure 2111 of the heating plate, as the main heating area, is directly corresponding to the outside of the side wall of the mouthpiece body 111. It can transfer heat evenly and efficiently to the side wall of the mouthpiece body 111 through a large contact area, which can reduce heat loss during the transfer process and ensure that more heat is transferred to the gas in the air outlet chamber through the side wall. This allows for more precise maintenance of the temperature inside the air outlet chamber, further reducing the possibility of aerosol liquefaction, enhancing the suppression effect on condensate accumulation, and making the suction experience more stable. In terms of installation and fixation, the fixing structure 2112 on the side of the heating element is used to connect with the side wall of the nozzle, which can firmly fix the heating element to the nozzle body 111. This prevents the heating element from shifting or falling off due to vibration, collision, or other factors during the use of the device, ensuring that the heating element and the side wall of the nozzle body 111 always maintain a good contact state, ensuring the continuity and stability of heat transfer. At the same time, the stable fixing structure 2112 also reduces the risk that the heating effect will be affected by the position of the heating element, improving the reliability of the entire heating assembly 20.

[0019] Furthermore, the heating element has a simple and compact structure, facilitating manufacturing and assembly. The integrated design or reasonable connection method between the main structure 2111 and the fixing structure 2112 does not excessively increase the volume and weight of the nozzle, which helps maintain the overall portability and ease of use of the aerosol generator, improving performance while also ensuring the product's practicality. In this embodiment, the fixing structure 2112 extends along the outer surface of the sidewall of the nozzle body 111 and adheres to the outside of the sidewall of the nozzle body 111. Regarding heat transfer efficiency, the extension and attachment of the fixing structure 2112 along the outer surface of the sidewall of the nozzle body 111 creates a larger contact area between the fixing structure 2112 and the sidewall of the nozzle body 111. This not only allows the main structure 2111 of the heating element to efficiently transfer heat, but the fixing structure 2112 can also transfer some heat to the nozzle body 111, effectively increasing the heat transfer path and area. This allows heat to be more evenly distributed on the sidewall of the nozzle body 111, and thus more effectively transferred to the interior of the air outlet chamber, further reducing the temperature difference between the air outlet chamber and the aerosol, and strengthening the suppression of condensate formation. From the perspective of installation stability, the clinging fixing structure 2112 can form a surrounding fixing force on the side wall of the nozzle body 111, which is more reliable than single-point or partial connection. No matter if the device is subjected to vibration, shaking or accidental collision during use, the fixing structure 2112 can firmly fix the heating element to the nozzle body 111, preventing the heating element from shifting, loosening or even falling off, ensuring that the heating element and the nozzle body 111 always maintain close contact, ensuring the continuity and stability of heat transfer, and reducing the risk of heating effect fluctuations due to changes in the position of the heating element. In addition, the attachment design extending along the outer surface better fits the shape of the nozzle body 111, making the fixing structure 2112 fit more closely to the side wall of the nozzle body 111 without adding excessive space. While ensuring the fixing and heating effects, it helps maintain the compactness of the overall nozzle structure, without adversely affecting the portability and feel of the device, thus balancing practicality and functionality. In other embodiments, the fixing structure 2112 is engaged with the side wall of the nozzle body 111. The engagement structure mainly includes a buckle provided on the fixing structure 2112 and a slot provided on the side wall of the nozzle body 111, and the buckle and the slot are structurally compatible. The buckle is a flexible, raised structure, and its material can be a metal with a certain degree of elastic deformation or a high-temperature resistant plastic, such as stainless steel or polyetheretherketone (PEEK). The raised part of the buckle can be wedge-shaped, with the inclined surface of the wedge facing the installation direction of the nozzle body 111, which facilitates guiding the buckle to slide smoothly into the slot during installation; while the vertical surface of the wedge faces the opposite direction, so that it can form a firm engagement with the inner wall of the slot after installation, preventing the buckle from easily falling out. The slot is correspondingly located on the side wall of the nozzle body 111, and its shape matches the protruding part of the buckle. It can be designed as a rectangular or trapezoidal groove. The depth of the slot should be slightly greater than the height of the protruding part of the buckle to ensure that the buckle can be fully engaged in the slot for a stable connection. At the same time, the inner wall of the slot must be smooth to avoid excessive frictional resistance when the buckle is engaged or disengaged, which would affect the ease of installation and disassembly. In terms of placement, multiple slots can be evenly arranged along the circumference of the side wall of the nozzle body 111, and correspondingly, the same number of clips can be arranged on the fixing structure 2112. For example, two symmetrically distributed slots can be arranged at each of the upper and lower ends of the side wall of the nozzle body 111, and four clips can be arranged on the fixing structure 2112 accordingly. This distribution method can make the force between the fixing structure 2112 and the side wall of the nozzle body 111 more uniform, further improving the stability of the connection.

[0020] During installation, the fixing structure 2112 is fitted onto the side wall of the nozzle body 111, aligning the buckle with the slot. A certain axial force is then applied, causing the buckle to pass through the slot's entrance under elastic deformation. Once the buckle is fully inside the slot, the elastic deformation returns to its original state, and the vertical surface of the buckle fits tightly against the inner wall of the slot, thus securing the fixing structure 2112 to the side wall of the nozzle body 111. For disassembly, simply apply a reverse pulling force to cause the buckle to elastically deform again, allowing it to disengage from the slot and separating the fixing structure 2112 from the side wall of the nozzle body 111. From the perspective of assembly efficiency, the snap-fit ​​structure does not require complicated tools or additional connectors (such as screws, glue, etc.). Installation can be completed simply by the cooperation between the fixing structure 2112 and the snap-fit ​​part (such as the slot and buckle) on the side wall of the nozzle body 111. The operation is simple and quick, which can greatly improve the assembly efficiency in the production process, reduce labor and time costs, and is suitable for large-scale mass production. Regarding connection stability, the snap-fit ​​structure, through the mechanical interlocking of the snap-fit ​​and the slot, ensures a stable connection between the fixing structure 2112 and the side wall of the nozzle body 111. This effectively resists external forces such as vibration and shaking generated during device use, preventing the heating element from shifting or falling off due to external forces. It also ensures the relative positional stability between the heating element and the side wall of the nozzle body 111, guaranteeing reliable heat transfer. Furthermore, the snap-fit ​​structure is relatively easy to disassemble. When maintenance or replacement of the heating element or nozzle body 111 is required, the two can be quickly separated, facilitating later maintenance. Although the snap-fit ​​method involves partial contact, the interlocking parts form a tight fit, ensuring that heat can be effectively transferred to the nozzle body 111 through the contact area.

[0021] In other embodiments, the fixing structure 2112 is magnetically connected to the side wall of the nozzle body 111. The fixing structure 2112 is provided with a first magnetic attractor on the side facing the side wall of the nozzle body 111. The first magnetic attractor can be a permanent magnet, such as a neodymium iron boron magnet. Its shape can be designed as a sheet, block or ring according to the shape of the fixing structure 2112 to ensure that there is enough contact area with the side wall of the nozzle body 111 to generate a stable magnetic force. A second magnetic element is provided on the inner sidewall or outer surface of the suction nozzle body 111 at a position corresponding to the first magnetic element. The second magnetic element can be a permanent magnet that can attract the first magnetic element, or it can be a metal sheet or block made of materials such as iron, cobalt, or nickel. If the suction nozzle body 111 is made of non-magnetic materials such as plastic, a mounting groove can be pre-set in its sidewall to embed the second magnetic element into the mounting groove. The outer surface of the second magnetic element should be flush with the outer surface of the sidewall of the suction nozzle body 111 to avoid affecting the fit between the fixing structure 2112 and the sidewall of the suction nozzle body 111. The magnetic poles of the first and second magnetic attractors are arranged with opposite poles to ensure that they can generate a reliable attraction. At the same time, multiple sets of mutually cooperating magnetic attractors can be arranged on the side wall of the fixing structure 2112 and the nozzle body 111 according to actual needs. For example, 3-4 sets of magnetic attractors can be evenly arranged along the circumference of the side wall of the nozzle body 111 to enhance the stability of the connection.

[0022] In terms of ease of assembly, the magnetic connection eliminates the need for complex alignment operations. Simply place the fixing structure 2112 close to the side wall of the nozzle body 111, and under the action of magnetism, the fixing structure 2112 will automatically adhere and position itself correctly, achieving rapid installation. Compared to snap-fit ​​methods, this eliminates the need for manual alignment of the clips and slots, further improving assembly efficiency and reducing labor intensity, making it particularly suitable for batch assembly on automated production lines. In terms of connection stability, the attraction between the magnetic components ensures that the fixing structure 2112 fits tightly against the side wall of the nozzle body 111. Under vibration and shaking conditions during daily use, this effectively prevents the fixing structure 2112 from falling off or shifting, ensuring the relative position of the heating element and the side wall of the nozzle body 111 remains stable and guaranteeing continuous heat transfer. Furthermore, when disassembly is required, only an external force slightly greater than the magnetic force is needed to separate the fixing structure 2112 from the nozzle body 111, facilitating future repairs and replacements and providing high maintenance convenience.

[0023] For heat transfer, the magnetic connection allows the fixing structure 2112 to fit tightly against the side wall of the nozzle body 111, reducing the gap between them and facilitating heat transfer from the heating part 21 to the nozzle body 111 through the fixing structure 2112. Furthermore, the magnetic component itself typically has a certain degree of thermal conductivity, so it does not excessively hinder heat transfer, ensuring effective heat transfer to the exhaust chamber, maintaining the temperature of the exhaust chamber, and reducing condensation. In this embodiment, the nozzle body 111 has a first notch 1111 on its side wall, which communicates with the air outlet 112. The main body structure 2111 includes a second notch corresponding to the first notch 1111. Regarding aerosol flow efficiency, the first notch 1111's communication with the air outlet 112 provides an additional channel for aerosol flow. The second notch's correspondence with the first notch 1111 prevents the main body structure 2111 from obstructing the first notch 1111 and also adapts to the side wall structure of the nozzle body 111, maximizing the heating area.

[0024] See Figure 4 As shown, the aerosol generator in this embodiment further includes a housing 30, which is fitted over the aerosol generator main body 10 and has a suction nozzle protrusion 31 fitted over the suction nozzle body 111. A suction nozzle opening 311 is provided at a position corresponding to the air outlet 112 on the suction nozzle protrusion 31. The heating component 20 is disposed between the suction nozzle body 111 and the suction nozzle protrusion 31. Firstly, the housing 30, fitted over the aerosol generator main body 10, provides effective physical protection for the aerosol generator main body 10, reducing damage to the core components inside the main body (such as the atomizing component and circuit module) from external collisions and friction, thus improving the structural stability and service life of the device. Simultaneously, the housing 30 can seal and shield the main body, reducing the probability of external dust, moisture, and other impurities entering the main body, ensuring the normal working environment of the main body. Secondly, the nozzle protrusion 31 of the outer shell 30 is fitted onto the nozzle body 111. On the one hand, it fixes and supports the nozzle body 111, enhancing the stability of the connection between the nozzle and the main body and preventing the nozzle body 111 from loosening or shaking during use. On the other hand, the nozzle protrusion 31 is positioned corresponding to the air outlet 112 to form a complete channel from the air outlet 112 to the nozzle opening 311, ensuring that the aerosol can be output smoothly. Furthermore, the structural design of the nozzle protrusion 31 can optimize the user's lip contact experience and improve the comfort of use. Furthermore, the heating component 20, positioned between the nozzle body 111 and the nozzle protrusion 31, offers several advantages: First, the nozzle protrusion 31 encloses and protects the heating component 20, reducing the risk of external impact or accidental contact, while also minimizing direct heat loss to the environment and improving heat utilization efficiency. Second, the heat generated by the heating component 20 acts simultaneously on both the nozzle body 111 and the nozzle protrusion 31, maintaining a consistent temperature for the protrusion. This prevents discomfort caused by excessively low temperatures when the user's lips contact the protrusion, enhancing the user experience. Third, the space between the nozzle body 111 and the nozzle protrusion 31 provides a stable installation environment for the heating component 20, and the clamping action further secures its position, ensuring good contact between the heating component 21 and the sidewall of the nozzle body 111, guaranteeing stable heat transfer, and effectively reducing condensate buildup and inhibiting bacterial growth. Finally, the heating component 20 is hidden between the nozzle body 111 and the nozzle protrusion 31, which avoids the heating component 20 being exposed, affecting the aesthetics of the device or causing safety hazards, thus balancing the practicality and safety of the device.

[0025] The aerosol generating main body 10 in this embodiment includes a power supply component and a control component electrically connected to the power supply component. The heating component 20 also includes a conductive part 22, with both ends of the conductive part 22 electrically connected to the control component and the heating component 21, respectively, to supply power to the heating component 21. The power supply component provides a stable power source for the heating component 21, while the conductive part 22 acts as an electrical connection bridge, with both ends reliably connected to the control component and the heating component 21, ensuring that the current can be efficiently and stably transmitted to the heating component 21, guaranteeing that the heating component 21 continuously generates heat. The structured electrical connection design avoids problems such as heating interruption or reduced heating efficiency caused by poor circuit contact, providing power assurance for the normal operation of the heating component 21, thereby ensuring the heating effect on the nozzle body 111 and the air outlet chamber, continuously reducing condensate accumulation and inhibiting bacterial growth. The control component, power supply component, and heating component 21 are electrically connected through the conductive part 22, enabling the control component to precisely control the working state of the heating component 21. For example, the control component can adjust the current or voltage output to the heating unit 21 according to preset programs or real-time detected parameters (such as nozzle temperature, suction frequency, etc.) to control the heating power of the heating unit 21, thereby precisely controlling the temperature of the nozzle body 111 and the outlet chamber. This not only avoids damage to the nozzle body 111 or user discomfort caused by excessive heating temperature, but also prevents the temperature from being too low and affecting the condensate suppression effect, ensuring that the heating temperature is always in the optimal range, further improving the safety and reliability of the device. The power supply component provides energy support for the entire device (including the heating component 20), while the control component coordinates the work of the heating component 20 and other functional modules, linking the heating process with the aerosol generation process. For example, the control component can simultaneously start the heating unit 21 when the user starts suction; after suction ends, it can delay shutting down the heating unit 21 or reduce the power, ensuring the heating effect during suction while avoiding unnecessary energy consumption and improving the energy efficiency ratio of the device. The outer casing 30, which is fitted over the aerosol generating main body 10, also prevents external damage to the conductive part 22.

[0026] See Figure 3As shown, the aerosol generating body in this embodiment has a positioning groove 13 on its side. The conductive part 22 includes an FPC lead, the two ends of which are electrically connected to the heating part and the power supply component, respectively. The FPC lead is embedded in the positioning groove 131. Regarding the positioning and fixing of the FPC lead, the positioning groove 131 provides a dedicated installation space for the FPC lead. After the FPC lead is embedded in it, it can be limited by the side walls and bottom of the groove, preventing displacement or detachment due to vibration or shaking during device use or movement. This ensures that the electrical connection points between the two ends of the FPC lead and the conductive part 22 and the power supply component always maintain stable contact, reducing problems such as poor circuit contact and heating interruption caused by loose leads, and ensuring the continuity and reliability of the power supply circuit of the heating component 20. From the perspective of protecting the FPC lead, the positioning groove forms a physical enclosure for the FPC lead, effectively isolating dust, moisture, and other impurities in the external environment, reducing the risk of contamination or corrosion of the lead. Meanwhile, the grooves prevent the FPC leads from directly rubbing or squeezing with other components inside the device, reduce wear on the insulation layer of the leads, extend the service life of the FPC leads, and reduce the probability of circuit failures caused by lead damage. FPC leads possess excellent flexibility and bendability. When embedded in the positioning groove, they fit snugly into the groove's shape, resulting in a more organized arrangement of the leads within the device. This reduces entanglement and interference between leads or with other components, preventing short circuits caused by messy wiring and further enhancing circuit safety. The positioning grooves enable embedded installation of the FPC leads, eliminating the need for additional fasteners (such as clips or tape) and saving internal space. This contributes to the miniaturization and compact structure of the aerosol generator. Simultaneously, the organized lead arrangement simplifies the internal structure, facilitating later assembly, inspection, and maintenance, thus reducing production and maintenance costs.

[0027] The aerosol generator in this embodiment further includes a button assembly 40, which includes a button body and a button control unit electrically connected to the control component. The button body provides the user with an intuitive, physical operating interface. The user can transmit commands to the control component via the button control unit through simple actions such as pressing, thereby controlling the device's functions, such as starting or stopping the heating component 20 and adjusting the heating temperature. Compared to touch or sensing methods without physical buttons, physical buttons provide clearer feedback, allowing the user to clearly perceive whether the operation is effective. Especially in low-light or blind operation scenarios, the accuracy of operation is higher, significantly improving the ease of use of the device. In terms of functional control precision, the button control unit is electrically connected to the control component, forming a stable command transmission path. When the user operates the button, the button control unit converts the mechanical action into an electrical signal and accurately transmits it to the control component. The control component processes the signal according to a preset program and then regulates the working state of the heating component 20 and other related components. For example, a short press of the button starts heating, while a long press adjusts the heating power. This tiered operation mode enables precise control of the heating process, avoiding heating abnormalities caused by misoperation, ensuring the device operates stably according to the user's needs, and further optimizing the suction experience. In terms of safety, the button assembly 40 can serve as a safety trigger mechanism for the device. For example, setting the button to require a long press for a certain period of time to activate the heating assembly 20, or using a multi-button combination operation, can effectively prevent accidental activation of the device due to children accidentally touching it or it being in their pockets, reducing safety hazards caused by misoperation. Simultaneously, the electrical connection between the button control unit and the control assembly allows for real-time feedback on the button status. When a button malfunctions, such as sticking, the control assembly can promptly detect and issue a warning or disconnect the relevant function, enhancing the device's safety.

[0028] Specifically, the sterilization method includes: continuously pressing the button body to a preset number of times, the button control unit sending a control signal to the control component, the control component controlling the heating component 20 to heat to a preset temperature; after a preset time, the control component controlling the heating component 20 to stop heating.

[0029] When a user needs to sterilize the nozzle, they must first press the button repeatedly until a preset number of presses is reached (e.g., 8 consecutive presses). During this process, the button transmits the mechanical pressing action to the button control unit. After detecting the preset number of consecutive presses, the button control unit sends a corresponding sterilization control signal to the control component. Upon receiving the control signal, the control component immediately activates the heating component 20 and outputs a specific current or voltage to the heating element 21 via the power supply component, causing the heating element 21 to begin heating. The heat is transferred through the side wall of the nozzle body 111 to the nozzle body 111 and the interior of the air outlet chamber, causing the temperature of the nozzle to gradually rise until it reaches the preset sterilization temperature (this temperature is usually set to a temperature that can effectively kill common bacteria, such as 60-80℃). While the heating component 20 maintains the preset sterilization temperature, after a preset time (e.g., 30 seconds to 5 minutes), the control component automatically issues a stop command, cutting off the power connection between the heating component 20 and the power supply component. The heating part 21 stops heating, and the temperature of the nozzle gradually drops back to room temperature, completing the entire sterilization process.

[0030] The aerosol generator in this embodiment further includes a prompting unit 50, which is electrically connected to a control component. The method further includes: the control component and the prompting unit 50 issuing a prompt message within a preset time. When the aerosol generator enters the sterilization process, during the preset time during which the heating component 20 maintains the preset sterilization temperature, the control component synchronously sends a control signal to the electrically connected prompting unit 50. Upon receiving the signal, the prompting unit 50 continuously or intermittently issues a prompt message according to a preset prompting method. Specifically, the prompting unit 50 can employ various prompting methods. For example, if it is a light prompt, the control component will control the LED light of the prompting unit 50 to flash at a specific frequency (e.g., flash once every 2 seconds); if it is an sound prompt, the buzzer of the prompting unit 50 will emit intermittent prompting sounds (e.g., emit a short beep every 3 seconds); if it is a vibration prompt, the vibration module of the prompting unit 50 will generate vibrations according to a fixed cycle (e.g., vibrate once every 5 seconds). These prompting messages will continue to exist throughout the preset sterilization time until the preset time ends and the control component controls the heating component 20 to stop heating, at which point the prompting unit 50 will stop emitting prompting messages.

[0031] In terms of user experience, the notification unit 50 allows users to clearly understand the operating status of the sterilization process. Since the sterilization process is carried out at high temperatures in the nozzle, it is difficult for users to directly observe the internal workings. However, the real-time feedback of the notification information can clearly inform users that "sterilization is in progress," avoiding users' misoperation due to uncertainty about whether the process has started or ended (such as interrupting sterilization midway or repeatedly triggering sterilization). This gives users more intuitive control over the sterilization process, improving the certainty and convenience of the user experience. From a safety perspective, continuous warning messages serve as a deterrent. During the preset time, the nozzle is in a high-temperature sterilization state. The warnings (such as flashing lights or audible alerts) from the warning unit 50 alert those nearby (especially children) that the device is working, preventing burns from touching the hot nozzle and reducing safety hazards. Simultaneously, it also prevents users from accidentally putting the nozzle in their mouths during the sterilization process, ensuring user safety. Regarding process standardization, the start and end of the prompts are strictly synchronized with the preset time of the sterilization process. When the prompts stop at 50, it means the sterilization process is complete. This correspondence helps users accurately determine whether sterilization is finished, eliminating the need for frequent checks or guesswork. It ensures the sterilization process is executed completely according to the preset time, guaranteeing the sufficiency of the sterilization effect and avoiding incomplete sterilization due to premature interruption. Furthermore, the prompting method of the prompting unit 50 can be flexibly set according to user needs or usage scenarios. For example, vibration prompts can be selected in quiet environments, and light prompts can be selected in low-light environments, enhancing the adaptability of the device. At the same time, the electrical connection design between the prompting unit 50 and the control components ensures seamless integration of the prompting function with the control of the entire sterilization process, without affecting the normal operation of other components, thus guaranteeing the coordination and stability of the device's functions.

[0032] In summary, the structural design of this application embodiment solves the technical problems of condensate affecting the suction experience and difficulty in ensuring the hygiene of the suction nozzle by heating and regulating the air outlet chamber of the nozzle. While improving the performance of the device, it also enhances the hygiene and safety of the product and has significant practical value.
