Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device and its control method. Background Technology

[0002] As one example, there is an aerosol generating device that produces an aerosol for a user to inhale by heating rather than burning a solid aerosol to form a matrix, such as a cigarette. As another example, there is a different aerosol generating device that produces an aerosol for a user to inhale by heating a liquid aerosol to form a matrix, such as e-liquid.

[0003] These devices typically include a display screen to show the battery level of the cells within the device. Users can use this displayed battery level to stop pumping and promptly plug in the charger when the battery is low. However, during the charging process, the actual battery level does not match the displayed value. This fails to accurately reflect the battery's charge level changes during charging, thus degrading the user experience. Summary of the Invention

[0032] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application. To facilitate understanding of this application, a more detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this specification is for the purpose of describing specific embodiments only and is not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] Figure 1 This is a schematic diagram of an aerosol generating device provided in an embodiment of this application.

[0034] like Figure 1 As shown, the aerosol generating device includes a nozzle 11, a liquid storage unit 12, a liquid transfer unit 13, a heating element 14, a circuit 15, a battery cell 16, a suction detector 17, and a display component 18. Figure 1In one example, the aforementioned components are integrally formed, and the aerosol generating device is a typical integrated device. In another example, the aerosol generating device includes an atomizer and a power supply assembly detachably connected to the atomizer. The atomizer is often referred to as a cartridge, and the power supply assembly is often referred to as a device. The circuit 15, the battery 16, and the inhalation detector 17 are located in the power supply assembly. The mouthpiece 11, the liquid storage unit 12, the liquid delivery unit 13, and the heating element 14 are located in the atomizer.

[0035] The nozzle 11 is used for users to inhale the aerosol generated by heating.

[0036] The liquid storage unit 12 is used to store a liquid aerosol forming matrix capable of generating aerosols. The liquid aerosol forming matrix can be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. For example, the liquid aerosol forming matrix may include water, solvents, ethanol, plant extracts, flavorings, fragrances, or vitamin mixtures. Flavorings may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring components. Fragrances may include ingredients capable of providing the user with a variety of flavors or aromas. Vitamin mixtures may be substances containing at least one of vitamins A, B, C, and E, but are not limited to. Additionally, the liquid aerosol forming matrix may include aerosol forming agents such as glycerol and propylene glycol.

[0037] The liquid transfer unit 13 is capable of transferring the liquid aerosol stored in the liquid storage unit 12 to the heating element 14 to form a matrix. For example, the liquid transfer unit 13 can be made of cotton fiber, ceramic fiber, glass fiber, or porous materials such as porous ceramics or porous glass, but is not limited thereto. The liquid transfer unit 13 can be constructed in a tubular, plate-like, or other regular or irregular shape.

[0038] The heating element 14 is a component used to heat the liquid aerosol forming matrix transferred through the liquid transfer unit 13. For example, the heating element 14 can be a metal wire, a metal plate, a ceramic heater, etc., but is not limited to these. Alternatively, the heating element 14 can be made of a conductive heating wire such as nickel-chromium wire, and can be arranged in a structure wound around the liquid transfer unit 13. The heating element 14 can be heated by an electric current supply, and heat is transferred to the liquid aerosol forming matrix in contact with the heating element 14 to heat the liquid aerosol forming matrix, thereby generating an aerosol.

[0039] Circuit 15 controls the overall operation of the aerosol generating device. Specifically, circuit 15 controls not only the operation of the battery cell 16 and the heating element 14, but also the operation of other components in the aerosol generating device. Furthermore, circuit 15 can determine whether the aerosol generating device is operable by checking the status of its components.

[0040] Circuit 15 includes at least one control unit. The control unit may include a logic gate array, or may include a combination of a microcontroller and a memory storing a program executable in the microcontroller. Furthermore, those skilled in the art will understand that circuit 15 may include another type of hardware.

[0041] Battery cell 16 provides power for operating the aerosol generating apparatus. For example, battery cell 16 can provide power to heat heating element 14 and can provide the power required to operate circuit 15. In addition, battery cell 16 can provide the power required to operate sensors, motors, etc. provided in the aerosol generating apparatus.

[0042] Cell 16 can be, but is not limited to, a lithium iron phosphate (LiFePO4) cell. For example, cell 16 can be a lithium cobalt oxide (LiCoO2) cell or a lithium titanate cell.

[0043] In one example, cell 16 is a rechargeable cell. An external power source can charge cell 16 through a charging interface (not shown) on the aerosol generating device. Generally, the charging process of cell 16 includes a constant current charging period and a constant voltage charging period. That is, cell 16 is first charged with a constant current, and when the voltage reaches a predetermined value, it switches to a constant voltage charging period for constant voltage charging, during which the current gradually decreases until cell 16 is fully charged.

[0044] The suction detector 17 is used to detect the user's suction action and generate a corresponding electrical signal, that is, to detect whether the aerosol generating device is being suctioned, so that the circuit 15, such as the processor, controls the operation of the battery cell 16, heating element 14, etc., according to the electrical signal. For example, it controls the battery cell 16 to provide power to the heating element 14 so that the heating element 14 atomizes the liquid aerosol to form a matrix. The suction detector 17 can be a common pressure sensor, differential pressure sensor, airflow sensor, etc.

[0045] An air inlet is provided near the suction detector 17 of the aerosol generating device. When the aerosol generating device is suctioned, the airflow enters through the air inlet, flows through the suction detector 17, the battery cell 16, the circuit 15, the heating element 14, etc., and then flows out through the suction nozzle 11. The dashed arrow in the figure roughly shows the airflow path.

[0046] Display component 18 is used to display the charge level of battery cell 16. For example, the charge level of battery cell 16 can be displayed digitally as a percentage between 0% and 100%.

[0047] It should be noted that, Figure 1 Only components relevant to this embodiment are shown. Those skilled in the art will understand that the aerosol generating apparatus may also include, in addition to... Figure 1Other common components besides those shown.

[0048] Figure 2 This is a schematic diagram of an aerosol generating device provided in an embodiment of this application.

[0049] like Figure 2 As shown, the aerosol generating device includes:

[0050] Chamber A contains a removable aerosol-generated article B.

[0051] The aerosol-generating article B preferably uses a solid aerosol-forming matrix, which may include one or more of the following: powder, granules, fragments, strips, or sheets of vanilla leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the solid aerosol-forming matrix may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is ​​heated.

[0052] When the aerosol generating article B is received in the chamber A, the heating element 140 can be inserted into the aerosol generating article B for heating to generate aerosol.

[0053] It should be noted that the heating method of the heating element 140 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, and air heating. The shape of the heating element 140 includes, but is not limited to, needle-shaped, pin-shaped, or sheet-shaped.

[0054] It should also be noted that, with Figure 2 Unlike the example, in other examples, it is also possible for the heating element 140 to be configured to heat at least a portion of the aerosol-generating article B, i.e., circumferential heating or peripheral heating, etc.

[0055] Cell 160 is used for power supply; cell 160 can be a rechargeable cell. For instructions on charging cell 160, please refer to the preceding content.

[0056] Circuit 150 is used to control the aerosol generating device; for example, to control the battery cell 160 to supply power to the heating element 140.

[0057] Circuit 150 includes a control unit. The control unit is configured as a hardware component to control the overall operation of the aerosol generation device. The control unit may be implemented as an array of logic gates, or as a combination of a microcontroller and a memory storing a program executable in the microcontroller. Those skilled in the art will understand that other forms of hardware may be used.

[0058] Display component 180 is used to display the charge level of battery cell 160. For example, the charge level of battery cell 160 can be displayed digitally as a percentage between 1% and 100%.

[0059] Based on the aforementioned aerosol generating device, in one example, the control unit is configured to determine the real-time power value of the battery cell and the corresponding power display value of the display component during the charging of the battery cell; when the absolute difference between the real-time power value and the power display value exceeds a first preset value, adjust the refresh time of a preset power scale to refresh the power display value of the display component according to the refresh time adjusted by the preset power scale.

[0060] In one example, the control unit can obtain the real-time voltage value of the battery cell through a voltage detection circuit. For example, the voltage detection circuit can use a common resistor voltage divider circuit. Based on the voltage divider signal and the known resistance value, the real-time voltage value of the battery cell can be determined.

[0061] The control unit is configured to determine the real-time charge value of the battery cell based on the real-time voltage value of the battery cell and pre-established relationship data between the battery cell voltage value and the real-time charge value.

[0062] In this example, the pre-established relationship between cell voltage and real-time battery capacity can be stored in the memory of the control unit or in a memory independent of the control unit. For reference, the relationship data can be established as shown in the table below:

[0063] Cell voltage (V) Real-time battery level (%) 4.1～4.2 100 4.04～4.1 95 4～4.04 90 3.97～4 85 3.93～3.97 80 3.89～3.93 75 3.86～3.89 70 3.83～3.86 65 3.8～3.83 60 3.77～3.8 55 3.75～3.77 50 3.73～3.75 45 3.69～3.73 40 3.65～3.69 35 3.61～3.65 30 3.57～3.61 25 3.53～3.57 20 3.49～3.53 15 3.45～3.49 10 Below 3.45 5

[0064] When the control unit obtains the real-time voltage value of the battery cell through the voltage detection circuit, it can obtain the corresponding real-time charge value by looking up a table. For example, if the control unit obtains a real-time voltage value of 4.05V for the battery cell through the voltage detection circuit, it can determine the corresponding real-time charge value as 95% using the above relationship data.

[0065] It should be noted that the relationship data shown in the table above can be determined through experiments, and the obtained real-time power values ​​can accurately reflect the actual power of the battery cell.

[0066] In one example, the control unit is configured to determine the refresh time of the preset battery scale based on the time it takes for the battery cell to be fully charged and the number of preset battery scales.

[0067] The battery level scale indicates the magnitude of the battery capacity. Once the battery level scale is determined, the number of scale points can be determined based on the full-scale range. The time required to fully charge a battery cell can be an empirical or experimental value.

[0068] For example, when displaying the battery level of cell 16 as a percentage between 0% and 100%, the battery level scale could be 1%, 1‰ (one-thousandth), etc. Assuming the battery level scale is 1‰ and the charging time to full is 95 minutes, then the number of battery level scale increments is 1000, and the refresh time for the scale is 5.7 seconds (95*60 / 1000). That is, with the refresh time remaining constant, the displayed battery level increases by 1‰ every 5.7 seconds.

[0069] In one example, the refresh time of the preset battery scale is equal to the product of the system time and the reference value.

[0070] The system time is a fixed value, such as 20ms or 100ms. Taking 20ms as an example, assuming the battery scale refresh time is 5.7s (95*60 / 1000), the base value is 285 (5.7*1000 / 20). Therefore, when the battery scale refresh time needs to be adjusted, only the base value needs to be adjusted. For example, reducing the base value from 285 to 250 reduces the battery scale refresh time from 5.7s to 5s.

[0071] In the above implementation, when the absolute difference between the real-time power value and the power display value exceeds a first preset value, the refresh time of the preset power scale is adjusted, thereby refreshing the power display value of the display component according to the refresh time adjusted by the preset power scale.

[0072] Following the example above, the refresh time of the battery scale is 5.7s. Assuming the refresh time of the adjusted battery scale is 6s, the battery display value of the display component will be refreshed every 6s, that is, the battery display value of the display component will increase by 1‰.

[0073] In the above implementation, the first preset value is an empirical value, generally between 1% and 10%, or between 1% and 8%, or between 2% and 8%, or between 2% and 6%, or between 4% and 6%, and in specific implementation it can be 5%.

[0074] In one example, the control unit is configured to decrease the refresh time of the preset battery scale if the difference between the real-time battery value and the displayed battery value exceeds the first preset value; and to increase the refresh time of the preset battery scale if the difference between the displayed battery value and the real-time battery value exceeds the first preset value.

[0075] That is, the greater the difference between the real-time battery level and the displayed battery level, the shorter the refresh time of the preset battery level scale. Conversely, the greater the difference between the displayed battery level and the real-time battery level, the longer the refresh time of the preset battery level scale. Thus, by refreshing the displayed battery level according to the refresh time adjusted according to the preset battery level scale, the difference between the displayed battery level and the real-time battery level can be reduced, avoiding the problem of mismatch between the actual battery level and the displayed battery level.

[0076] In one example, the control unit is configured to determine an adjustment factor for the refresh time of the preset battery level scale; and to use the product of the adjustment factor and the refresh time of the preset battery level scale as the refresh time after the preset battery level scale is adjusted.

[0077] The control unit calculates the adjustment coefficient based on the real-time power value and the power display value.

[0078] Similar to the proportional control method in PID control, the calculated adjustment coefficient is multiplied by the preset battery level refresh time, and this product is used as the refresh time after the preset battery level adjustment. This quickly reduces the difference between the displayed battery level and the real-time battery level.

[0079] For example, assuming the real-time battery level is 40% and the displayed battery level is 30%, the difference between the real-time battery level and the displayed battery level is 10%, while the first preset value is 5% and the second preset value is 90%, the refresh time of the preset battery level scale (1‰) needs to be reduced based on the above determination.

[0080] First, the adjustment coefficient is calculated as follows: (1-40%) / (1-30%) = 6 / 7. Then, the product of the adjustment coefficient and the refresh time of the preset battery scale is used as the refresh time after the preset battery scale is adjusted. For example, the product of the adjustment coefficient and the reference value is used as the adjusted reference value: 6 / 7 * 285 = 244.

[0081] In one example, the control unit is configured to keep the refresh time of the preset battery scale unchanged when the absolute difference between the real-time battery value and the battery display value does not exceed the first preset value.

[0082] In one example, the control unit is configured to adjust the refresh time of the preset battery scale when the absolute difference between the real-time battery value and the displayed battery value exceeds a first preset value and the displayed battery value is less than a second preset value.

[0083] In the above implementation, the second preset value can be the power display value corresponding to the moment when the battery transitions from constant current charging to constant voltage charging. For example, if the second preset value is 90%, the battery cell is in constant current charging when the power display value is less than 90%, and in constant voltage charging when the power display value is greater than or equal to 90%.

[0084] In one example, the control unit is configured to increase the refresh time of the preset battery scale when the displayed battery value is not less than the second preset value.

[0085] As mentioned earlier, when the displayed battery level is not less than the second preset value, the battery cell is in a constant voltage charging period, during which the charging current of the battery cell gradually decreases, or in other words, it is trickle charging. Furthermore, after the aforementioned steps, the displayed battery level and the real-time battery level are essentially matched. Therefore, the refresh time of the preset battery level scale can be increased to maintain the match between the displayed battery level and the real-time battery level during constant voltage charging. Generally, the refresh time of the preset battery level scale after adjustment during constant voltage charging is greater than the refresh time of the preset battery level scale after adjustment during constant current charging. For example, during constant voltage charging, if the adjustment coefficient is set to 2.5, the adjusted base value is 2.5 * 285 = 712. Generally, after increasing the refresh time of the preset battery level scale, the refresh time of the preset battery level scale can be kept unchanged without further adjustment.

[0086] Figure 3 This is a schematic diagram of the control method for the aerosol generating apparatus provided in the embodiments of this application. Specifically, it includes:

[0087] Step S11: During the charging of the battery cell, determine the real-time power value of the battery cell and the corresponding power display value of the display component;

[0088] Step S12: When the absolute difference between the real-time power value and the power display value exceeds a first preset value, adjust the refresh time of the preset power scale so as to refresh the power display value of the display component according to the refresh time adjusted by the preset power scale.

[0089] In one example, the refresh time of the preset battery scale is determined based on the time it takes for the battery cell to be fully charged and the number of preset battery scales.

[0090] In one example, the refresh time of the preset battery scale is equal to the product of the system time and the reference value.

[0091] In one example, if the difference between the real-time battery value and the displayed battery value exceeds the first preset value, the refresh time of the preset battery scale is reduced; if the difference between the displayed battery value and the real-time battery value exceeds the first preset value, the refresh time of the preset battery scale is increased.

[0092] In one example, an adjustment factor for the refresh time of the preset battery level is determined; the product of the adjustment factor and the refresh time of the preset battery level is used as the refresh time of the preset battery level after adjustment.

[0093] In one example, the adjustment coefficient is calculated based on the real-time battery level and the displayed battery level.

[0094] In one example, when the absolute difference between the real-time battery value and the displayed battery value does not exceed the first preset value, the refresh time of the preset battery scale remains unchanged.

[0095] In one example, when the absolute difference between the real-time battery value and the displayed battery value exceeds a first preset value and the displayed battery value is less than a second preset value, the refresh time of the preset battery scale is adjusted.

[0096] In one example, when the displayed battery value is not less than the second preset value, the refresh time of the preset battery scale is increased.

[0097] In one example, the real-time voltage value of the battery cell is obtained, and the real-time charge value of the battery cell is determined based on the real-time voltage value of the battery cell and pre-established relationship data between the battery cell voltage value and the real-time charge value.

[0101] Step S23: Determine if the battery level displayed is greater than or equal to 90%.

[0102] Step S24: If the displayed battery level is less than 90%, then proceed to step S24, which is to determine whether the real-time battery level minus the displayed battery level is greater than or equal to 5%.

[0103] Step S25: When |Real-time battery value - Battery display value| is greater than or equal to 5%, execute step S25, that is, adjust the refresh time of the preset battery scale;

[0104] Step S26: Determine if the battery cell charging is complete. If the battery cell charging is complete, end the control process; otherwise, continue with step S22.

[0105] Step S27: If the displayed battery level is greater than or equal to 90%, then proceed to step S27, which increases the refresh time of the preset battery level scale. After increasing the refresh time of the preset battery level scale, the refresh time of the preset battery level scale can be kept unchanged without further adjustment. After this step, proceed to step S26.

[0106] Step S28: When the difference between the real-time battery level and the displayed battery level is less than 5%, proceed with step S28, i.e., maintain the preset battery level refresh time unchanged. After this step, continue with step S26.
