Description

Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to an aerosol generating device and a control method thereof. Background Art

[0002] The aerosol generating device heats the aerosol generating product placed in the device to a certain temperature through a heating element, so that the volatile compounds therein are released in the form of aerosol for inhalation by the user. At present, although aerosol generating devices have made significant progress in reducing the release of harmful substances, existing product designs still have some limitations. For example, when many known heating devices are in operation, they simulate the average length of time a user smokes a traditional cigarette (such as 210 seconds) as a reference for the heating process, and set the heating curve according to this predetermined length of time. When the heating reaches the predetermined length of time, the device automatically stops heating. Although this design simulates the habit of traditional smoking to a certain extent, it ignores the diversity of users' smoking habits.

[0003] In fact, there are significant differences in the frequency of puffs, the duration of each puff, and the interval between puffs among different users. For those users with higher or lower puff frequencies, releasing aerosol according to a fixed heating time is obviously not flexible enough. This may result in users either not being able to obtain enough aerosol to meet their needs during actual use, or there are still incompletely released compounds at the end of heating, resulting in material waste and poor experience. Summary of the invention

[0004] The object of the present invention is to provide an aerosol generating device and a control method thereof, aiming to solve the problem that the existing aerosol generating device cannot provide aerosol according to the user's inhalation habits.

[0027] Furthermore, it also includes:

[0028] When it is detected that the average interval duration of the user's puffing actions reaches a predetermined puffing duration and the number of puffs of the user reaches a predetermined number, the heater is controlled to stop heating.

[0045] See also Figure 1 This embodiment provides an aerosol generating device for receiving an aerosol generating article 1000 and heating it to generate an aerosol for inhalation; comprising:

[0046] a chamber having an opening 40 through which an aerosol-generating article 1000 is removably mounted;

[0047] A heater 30 configured to heat the aerosol generating article 1000, the heater 30 at least partially extending within the chamber; when the aerosol generating article 1000 is placed within the chamber, the heater 30 is inserted into the aerosol generating article 1000 for heating, thereby causing the aerosol generating article 1000 to release a plurality of volatile compounds, and these volatile compounds are formed only by heating treatment;

[0048] Battery cell 10, used for power supply;

[0049] The circuit 20 has two ends connected to the battery cell 10 and the heater 30 respectively, and the circuit 20 is used to selectively control the heater 30 to heat through the first mode or the second mode; wherein, in the first mode, the circuit 20 is configured to control the heater 30 to heat according to a predetermined time, and stop heating when the heating time reaches the predetermined time; in the second mode, the circuit 20 is configured to control the heater 30 to stop heating when the number of puffs by the user reaches a predetermined number.

[0050] When the user loads the aerosol generating article 1000 into the chamber and starts the device, the heater 30 starts working. In the first mode, the heating will automatically stop after a preset time; in the second mode, the heating will stop after the user completes a certain number of puffs. After use, the device is turned off.

[0051] This embodiment can control the heating time of the puffing stage according to the number of puffs of the user, so as to adapt or be compatible with the different frequency of puffing habits of different users to provide a suitable amount of aerosol. By providing two different heating control options, the flexibility of use is increased to meet the needs of different users.

[0052] In a preferred embodiment, the DC supply voltage provided by the battery cell 10 is in the range of about 2.5V to about 9.0V, and the ampere of the DC current provided by the battery cell 10 is in the range of about 2.5A to about 20A.

[0053] Setting the DC supply voltage within the range of 2.5V to 9.0V can ensure that the battery cell 10 can be adjusted under different working conditions to adapt to different load requirements. The DC current is set within the range of 2.5A to 20A, so that the battery cell 10 can be charged and discharged faster, so as to quickly respond to the user's puffing needs and make the heater 30 heat up quickly, thereby improving the user's operating experience.

[0054] In a preferred embodiment, the design of the heater 30 can adopt a variety of shapes, including but not limited to pin-shaped, needle-shaped, rod-shaped, rod-shaped, column-shaped, and sheet-shaped or plate-shaped. This diverse form design enables the heater 30 to more flexibly adapt to the internal space requirements of different types of aerosol generating devices. For example, for some products that require a compact layout to save space, it may be more appropriate to use a slender heater 30 such as a needle or rod; while for applications that pursue fast and uniform heating effects, it may be inclined to choose a sheet or plate structure with a large area and a wide contact surface with the heated material. In addition, such a design also takes into account the issue of installation convenience. By making the heater 30 easy to insert, it not only simplifies the operating steps in the manufacturing process, but also facilitates the replacement of damaged parts during later maintenance. In some embodiments, the heater 30 can have a length of about 10 to 18 mm and an outer diameter of about 2 to 4 mm.

[0055] In some other optional embodiments, the heater 30 is configured to be arranged at least partially around or bounding the chamber; for example, the heater 30 is configured to be in a tubular shape that at least partially surrounds the chamber. When the aerosol generating article 1000 is received in the chamber, the heater 30 at least partially surrounds or encloses the aerosol generating article 1000 and heats the aerosol generating article 1000 from the periphery. And, when the aerosol generating article 1000 is received in the housing 10, it is at least partially contained and retained in the heater 30, and then the heater 30 surrounds the aerosol generating article 1000 from the outside and heats it, so that the aerosol generating article 1000 releases a plurality of volatile compounds, and these volatile compounds are formed only by heating. In some embodiments, the tubular heater 30 may have an inner diameter size of about 5.8 mm to 10 mm; in some embodiments, the heater 30 may have a longitudinal length of about 10 mm to 15 mm.

[0056] In some embodiments, the heater 30 may generally include a resistive heating element, and an auxiliary substrate for assisting the fixation and preparation of the resistive heating element. For example, in some embodiments, the resistive heating element is in the shape or form of a spiral coil, and the design of the spiral coil optimizes the surface area to volume ratio of the heating element, thereby improving the thermal efficiency. Or in some other embodiments, the resistive heating element is in the form of a conductive track combined with a carrier, and the conductive track can be a straight line, a curve or a complex pattern, providing a flexible arrangement to achieve uniform heating or local heating effects in a specific area. Or in some other embodiments, the resistive heating element is in the shape of a thin sheet, and the design of the thin sheet shape makes the resistive heating element have the characteristics of fast response and uniform heating.

[0057] In some embodiments, the heater 30 is an electromagnetic induction heater 30 that can be penetrated by a changing magnetic field to generate heat. Alternatively, in some other embodiments, the heater 30 is an infrared heater 30 that generates aerosol by radiating infrared rays to the aerosol generating article 1000 to heat the aerosol generating article 1000.

[0058] In some optional embodiments, the aerosol generating article 1000 preferably uses a tobacco-containing material that releases volatile compounds from the substrate when heated; or it can also be a non-tobacco material that can be heated and suitable for electric heating and smoking. The aerosol generating article 1000 preferably uses a solid substrate, which can include one or more of powder, particles, fragments, strips or sheets of one or more of herb leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the solid substrate can contain additional tobacco or non-tobacco volatile flavor compounds to be released when the substrate is heated.

[0059] In this embodiment, the device further includes: an indicator for providing instructions to the user, and the indicator is connected to the circuit 20 .

[0060] The indicator can intuitively show the user the status of the heater 30, such as whether heating is in progress, heating is complete, remaining power, fault warning, etc. This greatly improves the user experience, allowing the user to easily understand the current working status of the heater 30 and make corresponding operations or adjustments.

[0061] The indicator may be a vibration motor that generates vibration to remind the user of new messages or notifications. The indicator may also be a display screen that displays various texts, icons, and animations to present information to the user in an intuitive manner. The indicator may also be a sound reminder that reminds the user by emitting a corresponding indication sound.

[0062] In this embodiment, the device further includes: a puff detection sensor for sensing the user's puff action, and the puff detection sensor is connected to the circuit 20 .

[0063] The puff detection sensor can sense the user's puff action in real time and immediately trigger the heating mechanism of the heater 30 through the circuit 20. This instant response ensures that the user can immediately obtain the aerosol generated by the heating when puffing, improving the convenience of use and instant gratification. By only starting the heating when the user puffs, the design effectively avoids unnecessary energy consumption. This not only extends the battery life of the heater 30, but also reduces overall energy consumption.

[0064] In some embodiments, the puff detection sensor may be a microphone sensor, a MEMS sensor, etc. The circuit 20 determines the number of puffs of the user according to the sensing result of the puff detection sensor.

[0065] Or in some embodiments, the circuit 20 determines the user's puffing according to the temperature drop of the heater 30 exceeding a preset value. In use, the heater 30 is controlled by the circuit 20 to be kept at a constant temperature for heating, and when the user puffs, the temperature of the heater 30 caused by the air flowing through the heater 30 drops instantaneously, thereby determining the user's puffing action.

[0066] This design enables the electronic cigarette device to intelligently identify the user's puffing action without the user having to manually operate the switch. When the temperature of the heater 30 drops to a preset value due to the user's puffing, the circuit 20 responds immediately and starts the heating mechanism to generate the required aerosol for the user. This instant response improves the user experience and makes the puffing process more natural and smooth.

[0067] Alternatively, in some embodiments, the circuit 20 determines the user's puffing action based on the change in the power provided to the heater 30. In use, the circuit 20 needs to provide high power for an initial period of time, i.e., time t1, when starting the heating, so that the heater 30 can complete the preheating as quickly as possible; and once the preheating is completed and the puffing stage is entered, the power provided by the circuit 20 to the heater 30 is reduced to the power level required to maintain the heater 30 at the continuous heating temperature. At this time, if the user puffs on the aerosol generating article 1000, air is sucked through the heater 30 and the heater 30 is cooled to below the target temperature T2. In order to return the heater 3020 to the continuous heating temperature, the circuit 20 will provide power compensation, forming an instantaneous increase or jump peak of the output power. Then, by detecting the change in the power provided to the heater 30, the circuit 20 can determine the user's puffing action.

[0068] This design achieves efficient use of energy by controlling the power of the heater 30. When heating is not required, the circuit 20 can maintain a low power output, thereby saving energy. When the user inhales, the circuit 20 can quickly increase the power to ensure that the heater 30 can quickly reach the required temperature and generate aerosol. This dynamic power adjustment method is both energy-saving and efficient.

[0069] See also Figure 2 This embodiment also provides a control method for an aerosol generating device, comprising:

[0070] S101: Determine the mode of the aerosol generating device;

[0071] If the mode of the aerosol generating device is the first mode, step S102 is executed; if the mode of the aerosol generating device is the second mode, step S103 is executed.

[0072] S102: controlling the heater to heat for a predetermined time period through the circuit, and stopping heating when the heating time period reaches the predetermined time period;

[0073] S103: When the number of puffs by the user reaches a predetermined number, the circuit controls the heater to stop heating.

[0074] In some embodiments, the circuit 20 is configured to control the heater 30 to heat the aerosol generating article 1000 according to a predetermined temperature. For example, in some embodiments, the predetermined temperature may be staged; for example, the heater 30 may include a preheating stage and a puffing stage for the aerosol generating article 1000. Accordingly, the predetermined temperature may include a first temperature (i.e., a preheating temperature in the preheating stage) and a second temperature (i.e., a target temperature required in the puffing stage).

[0075] Specifically, it also includes: determining whether the aerosol generating device is in a preheating stage or a suction stage;

[0076] If the aerosol generating device is in the preheating stage, the heater 30 is controlled to heat the aerosol generating article 1000 according to the first predetermined temperature;

[0077] If the aerosol generating device is in the inhalation stage, the heater 30 is controlled to heat the aerosol generating article 1000 according to the second predetermined temperature.

[0078] By distinguishing between the preheating stage and the puffing stage, the circuit 20 can adopt different heating strategies. In the preheating stage, the heater 30 heats the aerosol generating article 1000 at a first predetermined temperature to ensure that the aerosol generating article 1000 can quickly reach a state suitable for puffing. In the puffing stage, the heater 30 heats at a second predetermined temperature to continuously generate an appropriate amount of aerosol to meet the user's puffing needs. This staged heating strategy not only ensures the heating effect, but also avoids unnecessary energy waste.

[0079] In some embodiments, heating is initiated upon detection of user input via a switch or the like, or by detection of insertion of an aerosol-generating article 1000 into the chamber.

[0080] This instant response mechanism ensures that users can get heated aerosol immediately when they need it without having to wait too long.

[0081] In some embodiments, once the heating is started, the circuit 20 controls the heater 30 to heat from room temperature during the preheating stage until the preheating temperature T1 is reached at time t1; the preheating temperature T1 is sufficient to vaporize the aerosol-forming substrate of the aerosol-generating article 1000 so as to form an aerosol. In some embodiments, the time t1 is preset; in some embodiments, the time t1 may be approximately 5s to 30s; more specifically, for example, the time t1 may be approximately 10s. In some embodiments, the preheating temperature T1 may be between 325 degrees Celsius and 385 degrees Celsius, particularly between 340 degrees Celsius and 370 degrees Celsius, and more particularly within the range between 350 degrees Celsius and 360 degrees Celsius.

[0082] In some embodiments, during the puffing phase, the circuit 20 controls the heater 30 to maintain heating at the target temperature T2 to continuously generate aerosol. In some embodiments, the target temperature T2 may be lower than the preheating temperature T1. In an embodiment, the target temperature T2 is high enough to continuously heat and generate aerosol and prevent the aerosol substances generated by the aerosol generating article 1000 from condensing. In some embodiments, the target temperature T2 may be between 255 degrees Celsius and 320 degrees Celsius, particularly between 285 degrees Celsius and 310 degrees Celsius.

[0083] Among them, the duration of the puffing phase is not predetermined. In this embodiment, the circuit 20 controls the heater 30 to stop heating when the number of puffs of the user reaches a predetermined number. Alternatively, the circuit 20 controls the duration of the puffing phase according to the number of puffs of the user. Adjusting the duration of the puffing phase by precisely controlling the number of puffs of the user has significant advantages and benefits for adapting or being compatible with the diverse puffing habits of different users and ensuring the provision of an appropriate and suitable aerosol supply. This personalized control method can not only enhance the user experience, but also effectively improve the adaptability and satisfaction of the product, and meet the needs of a wide range of user groups.

[0084] In some embodiments, a predetermined number of times is given.

[0085] Specifically, the predetermined number of times is selected based on the experience value and stored in the electronic device such as the control chip or the storage chip in the circuit 20. For example, the predetermined number of times may be 10 times, 12 times or 15 times, etc.; the circuit 20 controls the heater 30 to stop heating when the number of puffs taken by the user during the puffing stage reaches 10 times, 12 times or 15 times.

[0086] In some embodiments, it also includes:

[0087] When it is detected that the number of puffs of the user is one less than the predetermined number, the indicator is controlled to provide the user with an indication that one more puff is left.

[0088] For example, in a specific embodiment, the predetermined number of times is 15 times. When the user takes the 14th puff, the circuit 20 controls the indicator to remind the user that the aerosol generating article 1000 can still be puffed once; and when the user takes the 15th puff, the circuit 20 controls the heater 30 to stop heating the aerosol generating article 1000.

[0089] The indicator provides the user with a reminder of the remaining puff, so that the user can clearly understand his puff progress. This design allows the user to have a smoother and more comfortable use experience.

[0090] In some embodiments, it also includes:

[0091] When it is detected that the number of puffs taken by the user reaches a predetermined number, the control indicator provides the user with an indication that the aerosol generating article 1000 is completely consumed or exhausted. And / or, the control indicator prompts the user to replace a new aerosol generating article 1000. For example, when the number of puffs taken by the user during the puffing phase reaches 10, 12, or 15 times, the control indicator prompts the user that the aerosol generating article 1000 is exhausted, or prompts the user to replace a new aerosol generating article 1000.

[0092] In some embodiments, it also includes:

[0093] When it is detected that the average interval duration of the user's puffing action reaches a predetermined puffing duration and the number of puffs of the user reaches a predetermined number, the heater 30 is controlled to stop heating.

[0094] Among them, the interval between the user's puffing actions refers to the interval time between any two adjacent puffing actions of the user. The average interval duration of the user's puffing actions refers to the average value of all interval durations in all the user's puffing times up to the current time. In an embodiment, the average interval duration of the user's puffing actions is used to characterize the user's puffing frequency in the aerosol generating product 1000 to measure the speed of the user's puffing times; therefore, combining the average interval duration of the user's puffing actions with the user's puffing times can more accurately control the specific duration of the aerosol generating product 1000 being heated to provide an aerosol. This method can not only improve the user experience, but also ensure that the matrix material in the aerosol generating product 1000 is more fully and efficiently utilized.

[0095] As shown in Table 1, it shows the comparison between the predetermined duration and the predetermined number of average puff intervals that meet the puffing habits of different users' puffing frequencies.

[0096] Table 1

[0097]

[0098] According to the above table, the circuit 20 corresponds to different predetermined times that a given aerosol generating product 1000 can be inhaled according to the inhalation speed habits of different users, and then controls the heater 30 to stop heating when the number of inhalations of the user reaches the predetermined number. This ensures that everyone can enjoy the best atomization effect tailored for them, thereby greatly improving user experience satisfaction. In addition, this technology based on user behavior analysis can also help extend battery life and reduce energy consumption.

[0099] In some embodiments, it also includes:

[0100] When it is detected that the average interval duration of the user's puffing actions is greater than the maximum puff threshold or less than the minimum puff threshold, the control indicator provides the user with an indication that the puffing frequency is too fast or too slow.

[0101] For example, when the average interval length of the user's puffing action is greater than or equal to 22 seconds, the user is prompted that the puffing frequency is too slow; or, when the average interval length of the user's puffing action is less than or equal to 10 seconds, the user is prompted that the puffing frequency is too fast.

[0102] Puffing too fast may cause the user to ingest too much harmful substances, while puffing too slowly may not fully exert the effect of the aerosol generating device. By setting a reasonable puffing threshold and reminding the user in real time, the potential risks caused by improper puffing frequency can be effectively prevented.

[0103] In some embodiments, the predetermined number of times varies with the average interval duration between the user's puffing actions.

[0104] Different users may have different smoking habits. Some may puff quickly and continuously, while others may enjoy a slow pace. By dynamically adjusting the conditions for stopping the heater 30 according to the user's actual puffing behavior, personal preferences can be better adapted to provide a more personalized use experience.

[0105] Specifically, a given aerosol generating article 1000 has a reference number of puffs that can be drawn; the circuit 20 calculates the predetermined number of puffs based on the average interval length of the user's puffing action and the reference number of puffs. As shown in Table 2, it provides the alignment relationship for the circuit 20 to calculate the predetermined number of puffs based on the average interval length of the user's puffing action and the reference number of puffs.

[0106] Table 2

[0107]

[0108] In the above table, the circuit 20 uses the baseline number of puffs that the aerosol generating product 1000 has as a reference, and performs corresponding compensation for the number of times in combination with the average interval duration of the user's puffing action, thereby calculating a predetermined number of times that is suitable for the average interval duration of the puffing action, so as to determine whether to control the heater 30 to stop heating.

[0109] In some embodiments, determining the mode of the aerosol generating device comprises:

[0110] Determine whether the average interval duration of the user's puffing action is greater than a maximum threshold or less than a minimum threshold;

[0111] If the average interval duration of the user's puffing action is greater than the maximum threshold or less than the minimum threshold, the mode of the aerosol generating device is determined to be the second mode;

[0112] If the average interval duration of the user's puffing actions is less than or equal to the maximum threshold and greater than or equal to the minimum threshold, it is determined that the mode of the aerosol generating device is the first mode.

[0113] In this embodiment, when the average interval duration of the user's puffing action is greater than the maximum threshold or less than the minimum threshold, the circuit 20 will dynamically adjust the working time of the heater 30 according to the number of puffs detected. This means that if the user puffs at a relatively stable and moderate speed, the system will be able to control the heating process more accurately, thereby providing a more comfortable experience and helping to extend the service life of the device. On the contrary, if the average interval duration of the user's puffing action is less than or equal to the maximum threshold and greater than or equal to the minimum threshold, it indicates that the current user's usage pattern may deviate from the normal range. In this case, in order to ensure the safety of the product and avoid any potential risks caused by excessive use or improper operation, the circuit 20 will control the heater 30 to heat according to a predetermined duration. Although this approach sacrifices some personalized experience, it can effectively prevent safety problems caused by abnormally frequent or extremely rare puffing behaviors.

[0114] For example, in some optional embodiments, when the average interval duration of the user's puffing action is greater than the maximum threshold or less than the minimum threshold, the circuit 20 controls the heater 30 to heat according to the predetermined duration (e.g., 180s) of the puffing stage; when the heating duration of the heater 30 in the puffing stage reaches the predetermined duration (e.g., 180s), the heater 30 is controlled to stop heating. In this embodiment, the circuit 20 controls the heater 30 to heat according to the average interval duration of the user's puffing action as shown in Table 3.

[0115] Table 3

[0116]

[0117] When the various heater 30 control modes in the above table are used, the execution steps include:

[0118] After the heater 30 starts heating, the number of puffs of the user and the cumulative heating time are monitored and counted;

[0119] Calculate the average interval duration of the user's puffing actions, and determine whether the average interval duration of the user's puffing actions is greater than a maximum threshold and less than a minimum threshold;

[0120] If the average interval duration of the user's puffing action is less than or equal to the maximum threshold and greater than the minimum threshold, the predetermined number of times is calculated according to the average interval duration of the user's puffing action and the reference number of times, and the heater 30 is controlled to stop heating when the user's puffing number reaches the predetermined number of times;

[0121] If the average interval duration of the user's puffing action is greater than the maximum threshold, or the average interval duration of the user's puffing action is less than or equal to the minimum threshold, the heater 30 is controlled to heat according to the predetermined duration (for example, 180s) of the puffing stage, and the heater 30 is controlled to stop heating when the duration of the puffing stage reaches the predetermined duration.

[0122] In some embodiments, it also includes:

[0123] When it is detected that the time from the last puff of the user exceeds the predetermined forgetting time or no puffing action of the user is detected within the predetermined forgetting time, the heater 30 is controlled to stop heating. For example, when the circuit 20 detects that the time from the last puff of the user exceeds the predetermined forgetting time of 120s, the heater 30 is controlled to stop heating.

[0124] By setting a predetermined forgetting time and automatically stopping heating after the time has passed, it is possible to effectively avoid the potential safety hazards caused by the e-cigarette continuing to heat up due to long periods of unused electronic cigarettes. This design helps reduce the occurrence of accidents such as fires or burns and ensures the safety of users. In addition, when users forget to turn off the e-cigarette or do not use it for a long time, the automatic stop heating function can significantly reduce unnecessary energy consumption, help extend battery life, and reduce the impact on the environment.

[0125] In some embodiments, different ingredients in the aerosol generating product 1000 will produce different flavors and tastes at different temperatures; for example, when the temperature of the heater 30 is between 255 degrees Celsius and 320 degrees Celsius, it will produce a light or mild taste, and when the temperature of the heater 30 is between 325 degrees Celsius and 385 degrees Celsius, it will produce a strong or pungent taste.

[0126] Different taste experiences improve the overall satisfaction of the product, while also enhancing the user's different experiences and increasing the user's usage experience.

[0127] In some embodiments, it is determined whether the puffing time and puffing frequency of the user have reached the puffing threshold. If the puffing time and puffing frequency of the user have reached the puffing threshold, indicating that the user likes a stronger experience, the temperature of the heater is adjusted to a strong mode (for example, the temperature of the heater is adjusted to 325 degrees Celsius) to produce a strong or stimulating taste. If the puffing time or puffing frequency of the user has not reached the puffing threshold, indicating that the user likes a slow-paced experience, the temperature of the heater is adjusted to a light mode (for example, the temperature of the heater is adjusted to 255 degrees Celsius) to produce a light or soft taste.

[0128] By more accurately meeting the user's personal taste preferences, the overall user experience is significantly improved. Personalized services can enhance the product's appeal and the user's experience.
