Description

Technical Field

[0001] This invention belongs to the field of aerosol generation device control, and specifically relates to a control method and device for an aerosol generation device. Background Technology

[0002] Common aerosol generating devices often use a single metering mode for control. This approach is prone to problems in implementation, such as the remaining suction volume from the previous day limiting the suction volume on the following day, directly affecting the suction experience. Furthermore, a single metering mode cannot accurately measure and limit the actual suction volume of the user. Summary of the Invention

[0003] This invention provides a control method and apparatus for an aerosol generation device, which solves the problem in the prior art that the suction in the current metering cycle is easily affected by the previous metering cycle.

[0004] The basic solution of this invention is: a control method for an aerosol generating device, comprising:

[0005] Determine the current working mode based on the suction signal;

[0006] When the current working mode is metering mode, the power supply of the atomizing device is controlled according to whether the number of times the metering is reached within the preset time period, the current working mode is adjusted, and an upper limit prompt message is sent.

[0007] The number of times is updated by adding a unit measurement value when a single measurement cycle is completed. The completion of a single measurement cycle means that the timing of a single measurement cycle in the measurement mode reaches the standard measurement duration, or the measurement suction volume in the measurement mode reaches the preset atomization volume; the preset value of the number of times is greater than 1.

[0008] Beneficial effects: Upon receiving a suction signal, the system detects the current operating mode of the aerosol generator. If it is in metering mode, the system controls the atomization device's operation based on the number of metering cycles. If the number of metering cycles exceeds a preset value, the system will stop atomizing, reset the metering cycle, and exit the current metering mode.

[0009] The accumulation of metering counts occurs when, in each metering mode, the timer reaches the standard metering duration or the metered aspiration volume reaches the preset atomization volume. At this point, a unit metering value is added to the original metering value and updated. Then, the metering mode is canceled and waits for the next metering mode to be activated.

[0010] In this case, the metering mode limits the metering value based on both timing and measurement methods, and further restricts the normal operation of the nebulizer based on the metering value. Compared to limiting the metering solely based on the amount of atomized fluid, this case fully considers the time period factor, preventing the inhalation volume of the previous time period from affecting the inhalation behavior of the nebulizer in the next time period. Furthermore, by limiting the number of metering cycles, this case achieves precise metering control for different time periods, preventing users from using too much aerosol at once and protecting their health.

[0011] Furthermore, in the metering mode, when the number of metering cycles reaches a preset value, the power supply to the atomizer is interrupted, the metering mode is exited, and an upper limit reminder message is sent.

[0012] Furthermore, in the metering mode, if the number of metering cycles has not reached the preset value, and the current single metering cycle is completed without the next single metering cycle being performed within the preset cycle duration, the power supply to the atomizing device is turned off, and the metering mode is closed.

[0013] Furthermore, in the metering mode, if the number of metering attempts has not reached the preset value, and the current single metering cycle has not been completed, power is supplied to the atomizing device, and timing is performed based on the timing in the current single metering cycle, and metering is performed based on the metered inhalation volume in the current single metering cycle. When the updated timing reaches the standard metering duration of the corresponding single metering cycle, or the updated inhalation volume reaches the preset atomization volume of the corresponding single metering cycle, the single metering cycle is completed, and the number of metering attempts is increased by a unit metering value and updated.

[0014] Furthermore, the standard metering duration and preset atomization amount are the same in each of the single metering cycles.

[0015] Furthermore, the initial value of the number of measurements is 0, the unit measurement value is 1, and the preset value of the number of measurements is 2.

[0016] Furthermore, in the current metering cycle, timing and metering begin based on the suction signal.

[0017] Furthermore, the standard metering duration and preset atomization amount are different in each of the single metering cycles.

[0018] Furthermore, the method for setting the metering mode includes: the sensor collecting the corresponding coefficient; and when the coefficient reaches a preset requirement, switching the working mode of the aerosol generating device to the metering mode.

[0019] Furthermore, if the timer reaches the standard measurement duration during the single measurement cycle, a full measurement message will be displayed; if the measured suction volume reaches the preset atomization volume, a full measurement message will be displayed.

[0020] The present invention also provides a control device for an aerosol generating apparatus, comprising:

[0021] The signal acquisition module is used to acquire the suction signal;

[0022] The working mode adjustment module is used to adjust the working mode of the aerosol generating device and control the opening and closing of the metering module.

[0023] The metering module is used to update the storage module by adding a unit metering value to the number of metering cycles stored in the storage module when a single metering cycle is completed. The metering cycle is completed when the timing of a single metering cycle in the metering mode reaches the standard metering duration, or when the metered suction volume in the metering mode reaches the preset atomization volume.

[0024] The storage module is used to store the preset value of the number of times and the number of times the device is used;

[0025] The control module is used to control the power supply module to start and stop, control the working mode adjustment of the working adjustment module, control the number of measurements in the storage module to return to zero, and send an upper limit prompt message to the output module based on the comparison result between the number of measurements and the preset value of the number of measurements; the preset value of the number of measurements is greater than 1.

[0026] The output module is used to output the upper limit prompt information sent by the control module.

[0027] This metering control device can accurately measure the suction volume and present it to the user intuitively through prompts. Furthermore, the rational timing scheme greatly improves the user experience and is more beneficial to the user's health. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0035] First implementation method:

[0036] The first embodiment of the present invention provides a control method for an aerosol generating device, comprising: determining the current working mode based on a suction signal; in the current working mode being a metering mode, controlling the power supply of the atomizing device, adjusting the current working mode, and sending an upper limit prompt message based on whether the number of metering cycles within a preset time period has reached a preset value; wherein, the number of metering cycles is updated by adding a unit metering value when a single metering cycle is completed, and the completion of a single metering cycle means that the timing of a single metering cycle in the metering mode reaches the standard metering duration, or the metered suction volume in the metering mode reaches a preset atomization volume; the preset value of the number of metering cycles is greater than 1.

[0037] Upon receiving a suction signal, the system detects the current operating mode of the aerosol generator. If it's in metering mode, the system controls the atomizer's operation based on the number of metering cycles. If the number of cycles exceeds a preset value, the atomizer stops atomizing, resets the cycle count, and exits the current metering mode. Accumulated cycle counts occur when, in each metering mode, the timer reaches the standard metering duration or the metered suction volume reaches the preset atomization volume. In this case, a unit metering value is added to the original count, the count is updated, the metering mode is canceled, and the system waits for the next metering mode activation.

[0038] In this case, under the metering mode, the metering value is limited by both timing and metering methods. The metering value further restricts the normal operation of the atomizing device, fully considering the time period factor and preventing the inhalation volume of the previous time period from affecting the inhalation behavior of the atomizing device in the next time period. Furthermore, by limiting the number of metering cycles, precise metering control is achieved for different time periods, preventing users from consuming excessive amounts of atomized aerosol at once and protecting their health.

[0039] The implementation details of the control method in this embodiment are described below. The following details are provided for ease of understanding and are not essential for implementing this solution. The specific process of this embodiment is as follows: Figure 1 As shown, this embodiment is applied to a control device for an aerosol generating apparatus.

[0040] Step 101: Determine the current working mode based on the suction signal.

[0041] Specifically, the suction signal is a marker indicating the preparatory state of the aerosol generating device before it begins operation. For example, the suction signal is generated when the airflow sensor (microphone) of the aerosol generating device detects suction. When the airflow sensor detects that its own airflow exceeds a preset value, it determines that suction has occurred, and at the same time, the airflow sensor generates a suction signal into the aerosol generating device. These suction signals are captured in step 101.

[0042] Aerosol generating devices typically have multiple operating modes, such as standby mode (maintaining only basic synchronization), fixed power output mode, operating mode that automatically selects the corresponding power based on user preference, and metering mode that limits the user's inhalation volume. In step 101, upon detecting an inhalation signal, the current operating mode of the aerosol generating device is read, and then corresponding operations are performed according to the corresponding operating mode.

[0043] In some examples, the method for entering metering mode can be preset. For instance, this can be achieved through various means such as pressing the button n times consecutively, taking n puffs, shaking the product n times, inserting / removing the cartridge n times, pressing the button continuously for n seconds, taking n puffs continuously, tapping the battery n times, preset voice control, or remote terminal control. These actions will cause the battery to enter a setting mode and select the corresponding operating mode based on the chosen action. For example, setting n consecutive button presses as the activation signal for metering mode allows the user to switch to metering mode upon receiving the aerosol generator, regardless of whether they have taken any puffs.

[0044] Step 102: In the current working mode of metering mode, control the power supply of the atomizing device, adjust the current working mode, and send an upper limit prompt message based on whether the number of metering times in the preset time period has reached the preset number of times.

[0045] Specifically, the preset time period is usually set by the user or technical personnel, and is typically set to within 24 hours prior to the current time. For example, if the current time is 7:00 AM on November 20th, then the corresponding preset time period is from 7:00 AM on November 19th to 7:00 AM on November 20th of the same year.

[0046] The metering count is set by incrementing the metering value upon completion of a single metering cycle. A single metering cycle is one of many cycles within the metering mode, and the unit metering value is typically set to 1. Assuming the initial metering count is 'a', after completing a single metering cycle, the new metering count is 'a+1' and updated accordingly. The initial value for the metering count is usually set to 0. Thus, the metering count increments by 1 each time a single metering cycle is completed. The completion of a single metering cycle is defined as follows: the time for the single metering cycle in the metering mode reaches the standard metering duration, or the metered aspiration volume in the metering mode reaches the preset atomization volume. In other words, during a single metering cycle, as long as the duration reaches the standard metering duration or the metered aspiration volume reaches the preset atomization volume, the current single metering cycle is considered complete.

[0047] The preset number of cycles is usually set by the user or technician and represents the maximum number of single-dose cycles allowed within a preset time period. Typically, this preset number is greater than 1. For example, if the preset number is set to 2 and the preset time period is 24 hours prior to the current time, a single-dose cycle was performed between 10:00 PM and 12:00 AM on the 19th, and another single-dose cycle can still be performed between 5:00 AM and 6:00 AM on the 20th, meaning the suction operation can still be performed normally. In other examples, the preset number of cycles can be set to 3, 4, or 5, etc. A higher preset number of cycles provides more precise control over the aerosol generator and allows for more accurate control of the suction volume. A preset number of cycles of 2 is preferred.

[0048] In some examples, when the aerosol generator is in metering mode, when the number of metering cycles reaches a preset value, the power supply to the atomizer is interrupted, the number of cycles is reset to 0, the metering mode is exited, and an upper limit warning message is sent. In this case, when the number of cycles reaches the preset value, it is determined that all inhalation volume within the current preset time period has reached the limit saturation, thus resetting the number of cycles to the initial value, i.e., 0, then exiting the metering mode, and sending an upper limit warning message to inform the user that the current inhalation volume has reached saturation and further inhalation and atomization operations are not possible. The power supply interruption to the atomizer can also be replaced with other control methods that prevent the atomizer from operating normally.

[0049] In some examples, the metering mode shuts off the power supply to the atomizing device and turns off when the number of metering cycles has not reached the preset value, the current single metering cycle is completed, and no next single metering cycle is performed within the preset cycle duration.

[0050] The preset cycle time is usually set by technicians, typically 10 seconds. This means that if no selection is made to enter the next single-meter cycle within 10 seconds after the previous single-meter cycle is completed, the power supply to the atomizing device will be directly cut off, and the metering count will be stored for retrieval in the next single-meter cycle. When the next single-meter cycle is completed, the stored metering count will be incremented by one unit. It should be noted that the preset cycle time is not limited here, and relevant technicians can freely choose it according to actual needs.

[0051] In some examples, the metering mode, when the number of metering attempts has not reached the preset number, before the current single metering cycle is completed, controls the supply of power to the atomizing device, and starts timing based on the timing in the current single metering cycle, and starts metering based on the metered inhalation volume in the current single metering cycle. When the updated timing reaches the standard metering duration of the corresponding single metering cycle, or the updated inhalation volume reaches the preset atomization volume of the corresponding single metering cycle, the single metering cycle is completed, and the number of metering attempts is increased by a unit metering value and updated.

[0052] In other words, in metering mode, if the preset number of metering cycles has not been reached, the current single metering cycle is not completed. At this time, power is still supplied to the atomizing device to ensure its normal operation (based on the suction signal and the preset temperature-power supply variation pattern, the power supply is output according to the current temperature for atomization). When the current single metering cycle is completed, the pre-stored metering count 'a' from the previous cycle is retrieved from the storage module, a unit metering value is added to the metering count, and the result is updated as the metering count corresponding to the completion of the current single metering cycle.

[0053] Furthermore, this case also supports segmented continuous counting within a single metering cycle. That is, within the current single metering cycle, the stored past timing information j is directly retrieved, and timing k is calculated based on this j. k is then used to replace the original j. In other words, the single metering cycle does not need to be continuous; it can be divided into multiple segments for accumulation. For example, if a user inhales for a period of 10 minutes between 8:00 and 8:10, and the inhalation time is 10 minutes, the current inhalation time of 10 minutes is no longer updated when the user actively stops inhaling. Instead, the 10 minutes are stored directly. When the user resumes inhaling at 10:00, the timing is accumulated based on the stored 10 minutes until the total inhalation time of this single metering cycle reaches the standard metering time.

[0054] Correspondingly, in the current single-meter cycle, the stored previous vaping volume x is directly retrieved, and the detected vaping volume y is added to this vaping volume x to obtain the current cumulative vaping volume (x+y). (x+y) is then used to replace the original x. That is, the single-meter cycle does not need to be continuous, but can be divided into multiple segments for accumulation. For example, if a user vapes for a period of time from 8:00 to 8:10, and the vaping volume at that time is x, when the user actively stops vaping, the current vaping volume x is no longer updated. When the user stops vaping, x is directly stored. When the user vapes again at 10:00, the vaping volume at this time is accumulated based on the stored x, until the total vaping volume of this single-meter cycle reaches the preset vaping volume.

[0055] Specifically, the implementation of step 102 can be carried out using... Figure 2 The flowchart is used to illustrate:

[0056] S2-1, Is the current working mode metering mode? If so, proceed to step S2-2.

[0057] S2-2, Based on whether the number of measurements within the preset time period has reached the preset value, if yes, proceed to step S2-3; otherwise, proceed to step S2-4.

[0058] S2-3, interrupts the power supply to the atomizer, resets the metering count to the initial value, exits metering mode, and sends an upper limit warning message;

[0059] S2-4: Has the current single metering cycle been completed? If yes, execute S2-5; otherwise, execute S2-7.

[0060] S2-5: Within the preset cycle duration, should the next single metering cycle begin? If yes, execute S2-7; otherwise, execute S2-6.

[0061] S2-6, interrupts the power supply to the atomizer, stores the metering count, exits the metering mode, and sends a metering full message;

[0062] S2-7, Control the power supply to the atomizing device, obtain the stored timing duration j, and add the timing to the stored timing duration to obtain a new timing duration k; or accumulate the suction volume x in the current single metering cycle to obtain a new metered suction volume y; Execute step S2-8;

[0063] S2-8. Does the updated timing reach the standard measurement duration of the corresponding single measurement cycle, or does the updated suction volume measurement reach the preset atomization volume in the corresponding single measurement cycle? If yes, execute S2-9; otherwise, execute S2-7.

[0064] S2-9: Determine that the single metering cycle is complete, increase the unit metering value from the stored metering count and update it, then execute step S2-2.

[0065] Both methods involve stopping the power supply to the atomizer, but users can determine whether the current atomization is prohibited or in a buffer phase (i.e., the atomizer can resume normal operation for the next metering cycle by re-triggering the suction signal and entering metering mode) based on whether the output is "meter full" or "upper limit reminder".

[0066] It is worth noting that whether the current working mode is metering mode in step S2-1 can be determined by step 101. Step S2-7 can be interrupted, such as... Figure 3 As shown, it specifically includes:

[0067] S2-7-1, An interrupt signal is received, and step S2-7-2 is executed;

[0068] S2-7-2, controls to stop power supply to the atomizing device, stores the new timing duration k, and replaces the original timing duration j; or stores the new cumulative suction volume y and replaces the original metered suction volume x;

[0069] S2-7-3: Within the preset time after S2-7-2 is executed, is a suction signal received? If yes, then execute S2-7-4; otherwise, then execute step S2-7-5.

[0070] S2-7-4, Control the power supply to the atomizing device, obtain the stored timing duration k, and add the timing to the stored timing duration to obtain a new timing duration k'; Accumulate the suction volume y in the current single metering cycle to obtain a new metered suction volume y'; Execute step S2-8;

[0071] S2-7-5, Metering mode off.

[0072] The interruption signal can be generated when no suction signal is received from the microphone for a preset time. Furthermore, if no suction signal is received again within the corresponding preset time in step S2-7-2, the metering mode will be directly shut down.

[0073] In some examples, the standard metering duration and preset atomization amount in each of the single metering cycles correspond to themselves.

[0074] In other words, if a single metering cycle is uniform, then the standard duration and preset atomization volume are the same for all single metering cycles. If single metering cycles are differentiated, the standard duration and preset atomization volume for each single metering cycle can also be different. That is, the standard duration and preset atomization volume in each single metering cycle can be set according to user requirements. Similarly, the preset number of cycles in S2-2 can also be set through programming.

[0075] For example, in the first single metering cycle of 24 hours, the standard metering duration is t1, and the preset atomization amount is x1; in the second single metering cycle, the standard metering duration is t2, and the preset atomization amount is x2. The corresponding t1 can be different from t2, and x1 can also be different from x2.

[0076] Furthermore, the distinction between single metering cycles can be based on which single metering cycle it is in a preset time period, or on the time period in which the current single metering cycle is located.

[0077] For example, in a single-cycle pumping pattern, the suction volume setting at 12:00 PM is lower than the suction volume setting between 12:00 PM and 6:00 PM. A practical application of this is that suction volume can be limited by time periods, such as restricting the suction volume setting for users between 6:00 AM and 12:00 PM and between 6:00 PM and 12:00 AM compared to other time periods.

[0078] The preset atomization amount and standard metering duration for the corresponding single metering cycle can also be preset by the user. Meanwhile, the preset time period in step S2-2 can also be preset; this preset time period can be a fixed time period or a time period extending backwards from the current moment.

[0079] In some examples, the initial value of the preferred number of measurements is 0, the unit measurement value is 1, and the preset value of the number of measurements is 2.

[0080] In some examples, timing and measurement begin based on the suction signal within the current metering cycle. Specifically, step S2-7 directly executes S2-7-3 to ensure that the metering cycle only begins operation based on the suction signal. This avoids irrelevant suction actions by the user before they have actually suctioned after entering the metering cycle, thus improving the accuracy of the overall suction duration calculation.

[0081] In some examples, S2-5 determines whether to start the next single metering cycle within a preset cycle duration. The method for determining whether to enter the next single metering cycle in this step can be: the sensor collects the corresponding coefficient, and when the coefficient reaches the preset requirement, the working mode of the aerosol generating device is switched to metering mode.

[0082] Correspondingly, the methods for determining whether to start the next single metering cycle in S2-5 include: (1) receiving a suction signal from the microphone (airflow sensor) within a preset time period; (2) pressing the button on the surface of the aerosol generator n times within a preset time period, with the interval between two adjacent presses being less than a preset interval value; (3) pressing the button on the surface of the aerosol generator m times within a preset time period; (4) the sensor on the surface of the aerosol generator detecting a shaking amplitude exceeding a preset amplitude m times; (5) the sensor on the surface of the aerosol generator detecting a shaking amplitude exceeding a preset amplitude. The number of times the degree reaches n times, and the interval between two adjacent times is lower than the preset interval value; (6) the microphone (airflow sensor) of the aerosol generating device sends a suction signal m times within a preset time; (7) the microphone (airflow sensor) of the aerosol generating device sends a suction signal n times within a preset time, and the interval between two adjacent times is lower than the preset interval value; (8) the signal receiving end (sensing product insertion and removal) of the aerosol generating device detects that the number of times the cartridge is inserted and removed reaches m times; (9) the button on the surface of the aerosol generating device is continuously pressed for n seconds; (10) the microphone (airflow sensor) of the aerosol generating device works continuously for n seconds; etc. Among them, (2), (5) and (7) are intended to represent n consecutive times, where the preset interval value is the time interval determined to be continuous.

[0083] The steps of the various methods described above are only for clarity. In practice, they can be combined into one step or some steps can be split into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent. Adding insignificant modifications or introducing insignificant designs to the algorithm or process, but without changing the core design of the algorithm and process, are also within the scope of protection of this patent.

[0084] Second implementation method:

[0085] A second embodiment of the present invention provides a control device for an aerosol generating apparatus, such as... Figure 4 As shown, it includes:

[0086] Signal acquisition module 401 is used to acquire suction signals;

[0087] The working mode adjustment module 402 is used to adjust the working mode of the aerosol generating device and control the opening and closing of the metering module.

[0088] The metering module 403 is used to update the storage module by adding a unit metering value to the metering count stored in the storage module when a single metering cycle is completed; the metering cycle is completed when the timing of a single metering cycle in the metering mode reaches the standard metering duration, or when the metered suction volume in the metering mode reaches the preset atomization volume.

[0089] Storage module 404 is used to store the preset value of the number of times and the number of times the device is used;

[0090] The control module 405 is used to control the power supply module to start and stop, control the working mode adjustment of the working adjustment module, control the number of measurements in the storage module to return to zero, and send an upper limit prompt message to the output module based on the comparison result between the number of measurements and the preset value of the number of measurements; the preset value of the number of measurements is greater than 1.

[0091] Output module 406 is used to output the upper limit prompt information sent by control module 405.

[0092] In some examples, such as Figure 5 As shown, the metering module 403 includes multiple single metering cycle units 4031 and single metering cycle timing units 4032. Each single metering cycle unit 4031 updates the metering count in the storage module 403 upon completion and simultaneously outputs a metering full signal to the output module 406. The single metering cycle timing unit 4032 is used to time and wait for a suction signal or other signal after a single metering cycle unit 4031 has completed, in order to start the next single metering cycle unit 4031, or to start the previous single metering cycle unit 4031.

[0093] In some examples, such as Figure 6 As shown, the single metering cycle unit 4031 includes a single metering cumulative time calculation unit 40311, a single metering cumulative quantity calculation unit 40312, and a single metering cumulative time and quantity control unit 40313.

[0094] The single-meter cumulative time calculation unit 40311 is used to obtain the stored timing duration j, and to perform timing superposition on the basis of the timing duration to obtain a new timing duration k;

[0095] The single metering accumulation calculation unit 40312 is used to accumulate the metering and suction volume x in the current single metering cycle to obtain a new metering and suction volume y.

[0096] The single-meter cumulative time and volume control unit 40313 is used to complete the single-meter cycle when the updated time reaches the standard metering time of the corresponding single-meter cycle, or when the updated suction volume reaches the preset atomization volume of the corresponding single-meter cycle. The metering cycle is then completed, the metering count is increased by a unit metering value and updated in the storage module 404, and a cycle timing signal is sent to the single-meter cycle timing unit 4032.
