Description

Technical Field

[0001] This application belongs to the technical field of aerosol generation devices, and more specifically, relates to an atomizing component and an aerosol generation device. Background Technology

[0002] Aerosol generators can directly heat a solid aerosol matrix using an atomizing component to produce aerosols that users can inhale. In related technologies, aerosol generators can record the usage of the aerosol matrix by counting the number of puffs taken by the user. This also facilitates dynamic management of the aerosol generator's operation and user habits, improving the user experience. However, traditional methods of recording puff counts rely on energy changes (such as temperature changes) at the atomizing component and pressure changes sensed by the microphone as variables. This is computationally complex and easily affected by external environmental factors. For example, in a technology that uses temperature changes as a variable to count puffs, low accuracy in detecting temperature parameters can affect the accuracy of the statistical results and ultimately impact the user experience.

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.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] In the embodiments of this application, an atomizing component and an aerosol generating device are provided. Those skilled in the art will understand that the atomizing component is a key component within the aerosol generating device, used to contain and limit the aerosol matrix to be heated, and to provide a certain amount of heat to the aerosol matrix under energized conditions, causing the aerosol matrix to be heated and atomized, thus generating aerosol. A receiving cavity for containing the aerosol matrix is ​​formed on the atomizing component.

[0042] It should be noted that "aerosol matrix" refers to an article capable of forming aerosols under heating. Aerosols may contain volatile compounds. Aerosol matrices may include, but are not limited to, materials used for medical, health, and cosmetic purposes. For example, aerosol matrices can be prepared from plant-based materials, such as plant roots, stems, leaves, flowers, buds, and seeds.

[0043] In this embodiment, the aerosol matrix is ​​a solid matrix. Those skilled in the art will understand that the aerosol matrix can be a solid structure made from solid materials, or it can be a cotton-like structure that adsorbs a certain amount of liquid aerosol to form a matrix.

[0044] It should be noted that an "aerosol generating device" refers to a device that uses low-temperature heating technology to heat an aerosol matrix containing specific components to a suitable temperature, causing the corresponding components in the aerosol matrix to atomize and form inhalable aerosols. When operating, this device can generate aerosols containing specific components without producing an open flame, making them easy for users to inhale. Inhalation refers to the process of inhaling the aerosol into the user's mouth, nasal cavity, or lungs through the mouth or nose. This aerosol generating device produces aerosols through low-temperature heating rather than combustion, i.e., it utilizes Heat-Not-Burn (HNB) technology to generate aerosols.

[0045] In related technologies, aerosol generating devices can detect user inhalation actions and count the number of inhalations by using variables such as temperature changes at the atomizing component or air pressure changes at the microphone. However, both of these detection methods are susceptible to external environmental influences, leading to low detection accuracy and consequently, inaccurate counting of user inhalations, ultimately impacting the user experience.

[0046] To address the aforementioned issues and improve the accuracy of aerosol generators in counting the number of inhalations by users, this application provides an atomizing component. This atomizing component can enhance the accuracy of detecting temperature change trends by improving its structure, thereby improving the accuracy and reliability of aerosol generators with this atomizing component in counting the number of inhalations by users, and to some extent, improving the user experience.

[0047] The structure of the atomizing component provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0048] Please see Figures 1-2 In this embodiment, the atomizing component 10 includes a heating body 1, a connector 2, and a temperature detection element 3. The heating body 1 has a receiving cavity 101 for accommodating the aerosol matrix 40. The connector 2 is connected to the heating body 1, and at least a portion of the connector 2 is located in the receiving cavity 101. The temperature detection element 3 is connected to the connector 2 and is configured to be inserted into the aerosol matrix 40 together with the connector 2 to detect temperature changes within the aerosol matrix 40.

[0049] In the atomizing component 10 provided in this embodiment, when the aerosol matrix 40 is inserted into the receiving cavity 101 of the heating body 1, the temperature detection element 3 can be inserted into the aerosol matrix 40 together with the connector 2 under the guidance and support of the connector 2. When the user is not inhaling, the temperature inside the aerosol matrix 40 will gradually rise or remain stable under the influence of the heating body 1; when the user inhales, the temperature inside the aerosol matrix 40 will drop significantly due to the airflow generated by the user's inhalation action. At this time, the temperature drop trend detected by the temperature detection element 3 can be realized to correspond only to the inhalation action, which can effectively eliminate the interference of other factors (such as changes in ambient temperature, changes in cigarette structure, etc.) and realize the correspondence of a single variable to the number of times the user inhales.

[0050] In the atomizing component 10 provided in this embodiment, by improving the structure of the atomizing component 10 and utilizing the mutually cooperating connector 2 and temperature detection component 3, the temperature of the aerosol matrix 40 inside the receiving cavity 101 of the heating body 1 is detected. This effectively reduces the interference of the external environment on the detection accuracy of the temperature detection component 3, thereby improving the consistency and accuracy of its detection results with the number of user inhalations. This ensures that the output temperature change trend data can reliably support the corresponding component's statistics on the number of user inhalations. Furthermore, the atomizing component 10 also has the advantages of simple structure and adaptability to different heating methods. The technical solution provided in this embodiment not only helps improve the accuracy of statistical results but also enables the correspondence between a single variable and the number of user inhalations, helping to reduce the difficulty of counting the number of user inhalations and thereby improving the user experience of using the aerosol generating device with this atomizing component 10.

[0051] It should be noted that the temperature within the aerosol matrix 40 changes with the airflow. For example, when the user is not inhaling, the temperature of the aerosol matrix 40 can gradually increase or remain constant under the heating effect of the heating element 1. When the user inhales, the negative pressure generated in the oral cavity drives cold air from the external environment into the device through the air inlet or air intake channel of the aerosol generating device, flowing through the aerosol matrix 40. At this time, the low-temperature airflow comes into direct contact with the high-temperature aerosol matrix 40, rapidly absorbing heat through forced convection. The heat-absorbing airflow enters the user's oral cavity with the inhalation action, and in this process, it carries the heat away from the receiving cavity 101. At this time, the temperature at the aerosol matrix 40 drops significantly in a short period of time (usually manifested as a sharp drop in the temperature curve). The temperature detection element 3 inserted into the aerosol matrix 40 under the action of the connector 2 can acquire and record the above temperature changes. This temperature change can serve as a marker for a single inhalation by the user, used to statistically analyze the number of inhalations.

[0052] Please see Figure 2 The aerosol matrix 40 can be an elongated columnar structure. Specifically, the aerosol matrix 40 includes at least a heating section 41 and a filtering section 42. When the aerosol matrix 40 is inserted into the receiving cavity 101 of the heating body 1, at least a portion of the heating section 41 is located within the receiving cavity 101 and can cooperate with the heating element of the heating body 1, generating aerosol under the heating action of the heating element; the filtering section 42 cooperates with the heating section 41 and is at least partially located outside the receiving cavity 101. The aerosol generated by the heating section 41 can be filtered in the filtering section 42, and the temperature of the aerosol can be gradually reduced to a palatable temperature in the filtering section 42 to avoid scalding the user, while also optimizing the taste of the aerosol to a certain extent.

[0053] It should be noted that the atomizing component 10 provided in this embodiment is not affected by the structure of the aerosol matrix 40.

[0054] In this embodiment, the atomizing component 10 further includes a sealing ring 4, which is located outside the heating body 1 and connected to one end of the heating body 1, and is used to press-fit with the aerosol matrix 40 inserted in the receiving cavity 101.

[0055] The sealing ring 4 can improve the connection between the aerosol matrix 40 inserted into the receiving cavity 101 and the heating body 1.

[0056] Specifically, the sealing ring 4 can be a ring structure made of materials such as silicone.

[0057] Please see Figure 1 The sealing ring 4 is fitted around the outer side of the aerosol matrix 40 and is press-fitted with the aerosol matrix 40. At this time, the sealing ring 4 is press-fitted with the outer side wall of the aerosol matrix 40 and can contact one end of the heating body 1 that encloses the cavity 101.

[0058] In some embodiments, the temperature sensing element 3 includes at least one of a thermocouple and a negative temperature coefficient thermistor (NTC thermistor). A thermocouple can form a closed circuit using two different metal conductors, generating a thermoelectric potential based on the temperature difference between its two ends, and calculating the temperature using this potential difference. Thermocouples have good heat resistance and can directly contact high-temperature components for temperature detection. The resistance value of a negative temperature coefficient thermistor decreases as the temperature increases, and temperature detection can be achieved by detecting changes in its resistance value, offering the advantage of fast response. The structure and connection method of the temperature sensing element 3 described above have been disclosed in related technologies and will not be repeated here.

[0059] The connector 2 has high support and strength, and can be used to pierce the outer surface of the aerosol matrix 40 and insert itself into the aerosol matrix 40. The temperature sensing element 3, which is mounted on it, can be inserted into the aerosol matrix 40 together with the connector 2, so as to prevent the temperature sensing element 3 from being damaged in the process. The connector 2 helps to reduce the difficulty of inserting the temperature sensing element 3 into the aerosol matrix 40, and helps to extend the reliability and service life of the temperature sensing element 3.

[0060] Please see Figure 1 The heating body 1 provided in this application embodiment includes a connected base 11 and a heating element. The base 11 encloses and forms the aforementioned receiving cavity 101. The plug-in 2 can be connected to the base 11 and is spaced apart from the heating element. Correspondingly, the temperature detection element 3 connected to the plug-in 2 is also spaced apart from the heating element to avoid the heat generated by the heating element during operation affecting the normal detection accuracy of the temperature detection element 3 and its temperature change trend.

[0061] In some embodiments, the heating element can be integrally formed with the substrate 11. In this case, the heating element can be embedded in the substrate 11, or the heating element can be attached to the inner or outer sidewall of the substrate 11.

[0062] In other similar embodiments, the heating element can be detachably connected to the substrate 11 by means of pasting, sleeve, or other methods. For example, the heating element may include a threaded coil sleeved outside the substrate 11, which can cooperate with a corresponding magnetic induction element to heat the aerosol matrix 40 using the principle of electromagnetic induction; or, the heating element may be a resistive heating element pasted on the substrate 11, in which case the heating element can heat the aerosol matrix 40 located in the receiving cavity 101 by any one or more methods such as circumferential heating, center heating, and bottom heating. This embodiment does not limit the assembly method of the heating element and the substrate 11 or the heating method of the heating element. At the same time, the atomizing component 10 provided in this embodiment is compatible with any of the above heating methods.

[0063] Of course, it is important to note that the heating element should be positioned to avoid interfacing 2 and temperature sensing element 3, so as not to affect the detection accuracy of temperature sensing element 3.

[0064] In some embodiments, the substrate 11 includes a connected mounting member 111 and a limiting member 112. The mounting member 111 is a tubular structure, or a portion of the mounting member 111 is formed into a tubular structure. The limiting member 112 is located at one axial end of the tubular structure and connected to the mounting member 111 to limit the formation of the aforementioned receiving cavity 101. This receiving cavity 101 is an open cavity at one end, through which the aerosol matrix 40 can be inserted. (See also...) Figure 1 and Figure 2 The limiting member 112 has at least one air guide hole 1121 that allows airflow to pass through.

[0065] The limiting member 112 is used for positioning and limiting, which can help support the aerosol matrix 40 inserted into the receiving cavity 101. At the same time, the air guide hole 1121 formed on the limiting member 112 allows airflow to pass through. Under the suction action, the airflow entering the corresponding aerosol generating device can flow to the aerosol matrix 40 through the air guide hole 1121 and take away the heat in the aerosol matrix 40.

[0066] It should be noted that the tubular structure formed on the mounting component 111 can be a circular tubular structure, or a tapered tube, prismatic tube, elliptical cylindrical tube, or other different structures.

[0067] Please see Figure 1Taking the tubular structure as an example of a circular tube structure, the plug-in 2 is a circular plate structure with a certain thickness. It is fixedly set at one end of the mounting part 111 in the axial direction and is in contact with the axial end face of the mounting part 111 so as to connect with the mounting part 111.

[0068] In some embodiments, the mounting member 111 and the limiting member 112 are detachably connected. For example, the mounting member 111 can be detachably connected to the limiting member 112 by means of snap-fit ​​fixing or adhesive fixing.

[0069] The connector 2, at least partially located within the receiving cavity 101, can be connected to either the mounting member 111 or the limiting member 112, extending into the receiving cavity 101 relative to the base 11. When the connector 2 is connected to the mounting member 111, the connector 2 is located on the side wall of the receiving cavity 101. When the aerosol matrix 40 is inserted into the receiving cavity 101, the connector 2 can pass through the side wall of the aerosol matrix 40 and be inserted into the aerosol matrix 40, and the temperature sensing element 3 connected to the connector 2 can be inserted into the aerosol matrix 40 synchronously with the connector 2. When the connector 2 is connected to the limiting member 112, the connector 2 is located on the axial bottom wall of the receiving cavity 101. When the aerosol matrix 40 is inserted into the receiving cavity 101, as the aerosol matrix 40 is inserted, the distance between the aerosol matrix 40 and the limiting member 112 gradually decreases until the aerosol matrix 40 and the limiting member 112 are in contact. During this process, the connector 2 can be inserted into the end of the aerosol matrix 40, and the temperature detection member 3 connected to the connector 2 can be inserted into the aerosol matrix 40 synchronously with the connector 2.

[0070] Please see Figure 1 and Figure 2 The connector 2 is installed on the limiting member 112 and spaced apart from the air guide hole 1121. After the aerosol matrix 40 is installed in the receiving cavity 101, the connector 2 can be inserted into the aerosol matrix 40. At this time, the temperature detection element 3 can be inserted into the aerosol matrix 40 through the connector 2 to detect the temperature inside the aerosol matrix 40.

[0071] It should be noted that when a heating element or part of a heating element is provided on the limiting member 112, it is necessary to ensure that the heating element and the plug-in member 2 located on the limiting member 112 are spaced apart; when no heating element is provided on the limiting member 112, the heating element can be located on the side of the limiting member 112 that is close to the opening of the receiving cavity 101 in the axial direction, that is, along the axial direction of the tubular structure, the heating element and the limiting member 112 are spaced apart or adjacent to each other.

[0072] Please see Figure 3In some embodiments, the limiting member 112 is a circular sheet structure, and the connector 2 is disposed in the middle of the limiting member 112 along the axis of the tubular structure (i.e., the axis passing through the limiting member 112 is connected to the limiting member 112). The number of air guide holes 1121 is at least two and they are spaced apart around the outer periphery of the connector 2. In addition, the connector 2 can be an integral structure with the limiting member 112 or fixedly connected to it by means of adhesive bonding, or it can be disposed on the limiting member 112 by means of detachable connection.

[0073] For example, the number of air guide holes 1121 can be multiple and arranged in a ring array around the connector 2; or, multiple air guide holes 1121 can be arranged irregularly around the connector 2.

[0074] Specifically, the shape of the air guide hole 1121 includes at least one of circular and rectangular shapes. The two ends of the air guide hole 1121 are respectively connected to the opposite side surfaces of the limiting member 112 in the thickness direction to form an air guide hole 1121 penetrating the limiting member 112. In the thickness direction of the limiting member 112, the air guide hole 1121 can be a circular hole, an elliptical hole, a rectangular hole, or other irregular hole-like structures, etc.

[0075] To ensure the accuracy of the temperature sensing element 3 connected to the connector 2, the temperature sensing element 3 can be positioned at the end of the connector 2 pointing towards the receiving cavity 101, in which case the temperature sensing element 3 is exposed relative to the connector 2. When the connector 2 is inserted into the aerosol matrix 40, the temperature sensing element 3 is simultaneously inserted into the aerosol matrix 40 and the temperature of the aerosol matrix 40 is detected. To further improve the accuracy of the temperature sensing element 3's detection results and reduce the problem of decreased detection accuracy due to damage or dirt, and to effectively protect the temperature sensing element 3, the temperature sensing element 3 can be positioned inside the connector 2, in which case a cavity is formed within the connector 2 to accommodate the temperature sensing element 3. The connector 2 can provide a certain degree of protection for the temperature sensing element 3 and also helps to reduce the difficulty of installing the temperature sensing element 3.

[0076] Please see Figure 1 and Figure 4 The connector 2 has a hollow structure with an installation cavity 201 inside, and the temperature detection component 3 is located inside the installation cavity 201.

[0077] The connector 2 has a mounting cavity 201, and at least a portion of the connector 2 is located in the receiving cavity 101, such that when the temperature sensing element 3 is installed in the mounting cavity 201, at least a portion of the temperature sensing element 3 is also located in the receiving cavity 101, so that the temperature sensing element 3 can be inserted into the aerosol matrix 40.

[0078] In some embodiments, the connector 2 may be made of a material with high thermal conductivity and low heat capacity. Such materials have good thermal conductivity and can readily change their own temperature with variations in ambient temperature. Examples include copper, aluminum, silver, copper alloys, aluminum alloys, and aluminum nitride. The temperature sensing element 3 is located within the mounting cavity 201 of the connector 2 and remains in contact with the inner wall of the connector 2 to effectively detect temperature changes in the connector 2. Since the temperature of the connector 2 can change with the temperature of the aerosol matrix 40, the temperature change area detected by the temperature sensing element 3 is consistent with the temperature change trend of the aerosol matrix 40.

[0079] In other similar embodiments, the connector 2 may be provided with at least one communicating hole 202 connecting the mounting cavity 201 and the receiving cavity 101. Please refer to [link to relevant documentation]. Figure 4 At this time, the temperature sensing element 3 located in the mounting cavity 201 can be spaced apart from the inner wall of the connector 2. Correspondingly, the inner wall of the connector 2 is spaced apart around the radial circumferential sidewall of the temperature sensing element 3.

[0080] When the connector 2 is inserted into the aerosol matrix 40, part of the airflow generated by the user's suction can flow through the connecting hole 202 through the mounting cavity 201, so that the temperature detection element 3 located in the mounting cavity 201 can detect the temperature inside the aerosol matrix 40 by detecting the temperature change trend of the airflow, and finally obtain the temperature change trend of the aerosol matrix 40.

[0081] To further improve the smoothness of insertion of the connector 2 into the aerosol matrix 40 and ensure that the connector 2 can be inserted along with the aerosol matrix 40 into the receiving cavity 101, in some embodiments, the connector 2 is configured as a rod-shaped or columnar structure with one end pointed, and the end pointing towards the receiving cavity 101 is a cone-shaped or pyramidal-shaped sharp corner, or other reduced structure, to help reduce the resistance when inserted into the aerosol matrix 40.

[0082] Please see Figure 4 The connector 2 includes a connecting part 21 and an insertion part 22 connected together. The connecting part 21 can be connected to the limiting member 112 of the heating body 1. One end of the insertion part 22 is connected to the connecting part 21, and the other end points to the receiving cavity 101. The aforementioned connecting hole 202 is formed in the insertion part 22.

[0083] Specifically, the aforementioned receiving cavity 101 can be formed solely by the insertion portion 22, or it can be formed by both the insertion portion 22 and the connecting portion 21. When the connector 2 is inserted into the aerosol matrix 40, both the insertion portion 22 and the connecting portion 21 can be inserted into the aerosol matrix 40.

[0084] It should be noted that the insertion part 22 is provided with a channel for the circuit to pass through at the end opposite to the connection part 21. The temperature detection element 3 can pass through the channel and extend into the receiving cavity 101. Alternatively, the conductive line and / or signal line can be connected to the temperature detection element 3 located in the receiving cavity 101 through the channel.

[0085] It is understood that the embodiments of this application can effectively improve the accuracy of temperature detection of the temperature change within the aerosol matrix 40 by the temperature detection component 3 through the atomizing component 10 described above. By directly detecting the temperature change trend inside the aerosol matrix 40, the interference of the external environment on the statistical results is reduced, thereby effectively improving the accuracy of the detected temperature parameters. This allows the output temperature change trend data to reliably support the corresponding component in counting the number of times the user inhales, which helps to reduce the difficulty of counting the number of times the user inhales. Based on this, the user experience of using the aerosol generating device with the atomizing component 10 is improved.

[0086] Based on the same concept, in a second aspect, embodiments of this application also provide an aerosol generating device, including the atomizing component 10 described in any of the above claims, and a controller 20, wherein the controller 20 is electrically connected to the temperature detection element 3 in the atomizing component 10; wherein, in response to the detection result of the temperature detection element 3, the controller 20 records the number of suctions based on the number of temperature fluctuations of the temperature detection element 3.

[0087] In the aerosol generating device provided in this application embodiment, the temperature change trend of the temperature detection element 3 in the atomizing component 10 can be obtained by the controller 20, and the accurate statistics of the number of times the user inhales can be realized based on this single variable. It has the advantage of simple structure and helps to improve the user experience.

[0088] In this embodiment, the number of fluctuations in the temperature detection element 3 corresponds one-to-one with the number of suction cycles.

[0089] Specifically, it can be defined that when the temperature parameter detected by the temperature sensor 3 decreases by more than a preset value within a preset time range, an effective temperature fluctuation is generated. That is, when the temperature parameter detected by the temperature sensor 3 decreases by more than a preset value within a unit time range, it is determined that there is a suction action, and the number of suctions recorded by the controller 20 is incremented by one.

[0090] The preset time range can be determined based on the experimental data or historical data obtained by the user. Similarly, the preset value of the temperature parameter can also be determined based on the experimental data.

[0091] In some embodiments, the aerosol generating apparatus further includes a power supply component 30. (See also...) Figure 5 and Figure 6The power supply component 30 is electrically connected to the atomizing component 10 and the controller 20, and is used to supply power to the atomizing component 10 and the controller 20.

[0092] The controller 20 mentioned above can be a printed circuit board (PCB) containing a processor. The processor can be a central processing unit (CPU), or other general-purpose processors, microcontrollers, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), programmable logic controllers (PLCs), discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor.

[0093] In addition to the processor described above, the controller 20 may also include a memory and a computer program stored in the memory that can run on the processor, such as a program that stores and records the number of suctions based on temperature parameter fluctuations. This program has been disclosed in related technologies. The processor can execute the computer program to count the number of suctions performed by the user.

[0094] For aerosol generating devices, counting the number of suction ports used by users helps improve the user experience, while also helping users intuitively understand suction frequency and daily suction volume, and helping users understand their own usage habits through data reference.

[0095] Of course, the aerosol generating device also has other structures, such as a shell covering the atomizing component 10.

[0096] It is understood that the embodiments of this application provide an aerosol generating device that can achieve a one-to-one correspondence between temperature parameters and the number of suction ports and realize the counting of the number of suction ports.

[0097] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0098] The above description is merely a preferred embodiment of this application and is 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.
