Aerosol generating device and control method thereof

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 26, 2024, with application number 202410117939.X, entitled “Aerosol Generating Device and Control Method Thereof,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of aerosol generation, and in particular to an aerosol generating device and a control method thereof. Background Art

[0004] As an example, there is an aerosol-generating device that generates an aerosol for a user to inhale by heating, rather than burning, a solid aerosol-forming substrate, such as a cigarette. As another example, there is another aerosol-generating device that generates an aerosol for a user to inhale by heating a liquid aerosol-forming substrate, such as a cigarette oil.

[0005] Such devices typically feature a display screen that displays the battery level. This display allows users to stop vaping and promptly recharge the device when the battery level is low. However, because battery level calculations are often imprecise, this can easily lead to anomalies. For example, a high battery level may be displayed while the actual battery voltage is low, misleading the user into believing they can continue vaping for a longer period or take more puffs. However, if the user continues vaping, the low battery voltage will cause heating to cease, preventing the user from inhaling aerosol, thus reducing the user's vaping experience.

[0006] Application Contents

[0007] The present application provides an aerosol generating device and a control method thereof to avoid the problem in existing devices where the displayed battery cell power value is high while the actual battery cell voltage is low, thereby causing the user to be unable to inhale the aerosol and reducing the inhalation experience.

[0008] On the one hand, the present application provides an aerosol generating device, comprising: a battery cell for providing electricity; a display component for displaying the battery level of the battery cell; a heating element for atomizing an aerosol-forming matrix to generate an aerosol; a controller configured to obtain a real-time voltage value of the battery cell and a battery level currently displayed by the display component; and when the real-time voltage value of the battery cell is lower than a preset voltage threshold and the battery level currently displayed by the display component is higher than a first preset battery level threshold, controlling the display component to calibrate the currently displayed battery level.

[0009] On the other hand, the present application provides a control method for an aerosol generating device, wherein the aerosol generating device includes: a battery cell for providing electricity; a display component for displaying the power level of the battery cell; and a heating element for atomizing an aerosol-forming matrix to generate an aerosol. The method includes: obtaining a real-time voltage value of the battery cell and a power level currently displayed by the display component; when the real-time voltage value of the battery cell is lower than a preset voltage threshold and the power level currently displayed by the display component is higher than a first preset power threshold, controlling the display component to calibrate the currently displayed power level.

[0010] The aerosol generating device and control method provided above control the display component to calibrate the currently displayed power value when the real-time voltage value of the battery cell is lower than the preset voltage threshold and the power value currently displayed by the display component is higher than the preset power threshold, thereby avoiding the problem in existing devices where the displayed battery cell power value is high while the actual battery cell voltage is low, resulting in the user being unable to inhale the aerosol, thereby improving the user's puffing experience.

[0018] FIG1 is a schematic diagram of an aerosol generating device provided in an embodiment of the present application.

[0019] As shown in Figure 1 , the aerosol generating device includes a mouthpiece 11, a liquid storage unit 12, a liquid transfer unit 13, a heating element 14, a circuit 15, a battery cell 16, a puff detector 17, and a display unit 18. In the example of Figure 1 , the above components are formed integrally, and the aerosol generating device is a typical one-piece device. In another example, the aerosol generating device includes an atomizer, which is often referred to as a cigarette cartridge, and a power supply assembly that is detachably connected to the atomizer. The atomizer is often referred to as a cigarette cartridge, and the power supply assembly is often referred to as a cigarette rod. The circuit 15, battery cell 16, and puff detector 17 are located in the power supply assembly. The mouthpiece 11, liquid storage unit 12, liquid transfer unit 13, and heating element 14 are located in the atomizer.

[0020] The mouthpiece 11 is used for the user to inhale the aerosol generated by heating.

[0021] Liquid storage unit 12 is used to store the liquid aerosol that can generate aerosol and forms matrix.Liquid aerosol forms matrix and can be the liquid that comprises the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, liquid aerosol forms matrix and can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, liquid aerosol forms matrix and can comprise the aerosol forming agent as glycerol and propylene glycol.

[0022] The liquid transfer unit 13 is capable of transferring the liquid aerosol-forming substrate stored in the liquid storage unit 12 to the heating element 14. For example, the liquid transfer unit 13 may be made of, but is not limited to, a porous material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic or porous glass. The liquid transfer unit 13 may be configured in a tubular, plate-like, or other regular or irregular shape.

[0023] The heating element 14 is a component for heating the liquid aerosol-forming substrate delivered via the liquid delivery unit 13. For example, the heating element 14 may be a metal wire, a metal plate, a ceramic heater, etc., but is not limited thereto. Alternatively, the heating element 14 may be formed of a conductive heating wire, such as a nickel-chromium wire, and may be arranged to be wound around the liquid delivery unit 13. The heating element 14 is heated by a supply of electric current and transfers heat to the liquid aerosol-forming substrate in contact with the heating element 14, thereby heating the liquid aerosol-forming substrate and generating an aerosol.

[0024] The circuit 15 can control the overall operation of the aerosol-generating device. Specifically, the 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, the circuit 15 can determine whether the aerosol-generating device is operational by checking the status of its components.

[0025] The circuit 15 includes at least one controller. The controller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. In addition, those skilled in the art will appreciate that the circuit 15 may include another type of hardware.

[0026] The battery cell 16 provides power for operating the aerosol generating device. For example, the battery cell 16 can provide power to heat the heating element 14 and can provide power required to operate the circuit 15. In addition, the battery cell 16 can provide power required to operate sensors, motors, etc. provided in the aerosol generating device.

[0027] The battery cell 16 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery cell. For example, the battery cell 16 may be a lithium cobalt oxide (LiCoO2) battery cell or a lithium titanate battery cell. The battery cell 16 may be a rechargeable battery cell or a disposable battery cell.

[0028] Puff detector 17 is used to detect the user's puff action and generate a corresponding electrical signal, that is, to detect whether the aerosol generating device is being puffed. This allows circuit 15, such as a processor, to control the operation of battery cell 16, heating element 14, etc. based on the electrical signal. For example, it controls battery cell 16 to supply power to heating element 14, so that heating element 14 atomizes the liquid aerosol to form the substrate. Puff detector 17 can be a common pressure sensor, differential pressure sensor, airflow sensor, etc.

[0029] An air inlet is provided at a position of the aerosol generating device adjacent to the puff detector 17. When the aerosol generating device is puffed, air flows in through the air inlet, flows through the puff detector 17, the battery cell 16, the circuit 15, the heating element 14, etc., and then flows out through the nozzle 11. The dotted arrow in the figure roughly shows the airflow path.

[0030] The display component 18 is used to display the power level of the battery cell 16. For example, the power level of the battery cell 16 can be displayed digitally, which can be a percentage between 1% and 100%.

[0031] It should be noted that Figure 1 only shows components related to this embodiment. Those skilled in the art will appreciate that the aerosol generating device may further include other common components in addition to those shown in Figure 1 .

[0032] FIG2 is a schematic diagram of an aerosol generating device provided in an embodiment of the present application.

[0033] As shown in Figure 2, the aerosol generating device includes:

[0034] a chamber A in which an aerosol-generating article B is removably received;

[0035] The aerosol-generating product B preferably adopts a solid aerosol-forming matrix, which may include one or more of powder, particles, fragments, strips or flakes of one or more of vanilla leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; alternatively, the solid aerosol-forming matrix may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is ​​heated.

[0036] The heating element 140 can be inserted into the aerosol-generating article B to heat the aerosol-generating article B when the aerosol-generating article B is received in the chamber A, so as to generate aerosol.

[0037] 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 thin sheet-shaped.

[0038] It should also be noted that, unlike the example in FIG. 2 , in other examples, the heating element 140 is configured to heat around at least a portion of the aerosol-generating article B, which is commonly known as circumferential heating or peripheral heating, etc., which is also feasible.

[0039] The battery cell 160 is used for power supply; the battery cell 160 can be a rechargeable battery cell or a disposable battery cell.

[0040] The circuit 150 is used to control the aerosol generating device; for example, it controls the battery cell 160 to provide power to the heating element 140 .

[0041] The circuit 150 includes a controller 151. The controller 151 is a hardware component configured to control the overall operation of the aerosol generating device. The controller 151 can be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory, with the memory storing a program executable by the microprocessor. Those skilled in the art will appreciate that the processor can be implemented in other forms of hardware.

[0042] The display component 180 is used to display the power level of the battery cell 160. For example, the power level of the battery cell 160 can be displayed digitally, which can be a percentage between 1% and 100%.

[0043] Based on the above-mentioned aerosol generating device, in one example, the controller 151 is configured to obtain the real-time voltage value of the battery cell and the power value currently displayed by the display component; when the real-time voltage value of the battery cell is lower than the preset voltage threshold and the power value currently displayed by the display component is higher than the first preset power threshold, the display component is controlled to calibrate the currently displayed power value.

[0044] In this example, the controller 151 can obtain the real-time voltage value of the battery cell through the voltage detection circuit 1511. For example, the voltage detection circuit 1511 can adopt a common resistance voltage divider circuit, and the real-time voltage value of the battery cell can be determined according to the voltage division signal and the known resistance value.

[0045] The preset voltage threshold is greater than the minimum operating voltage of the controller. For example, assuming that the minimum operating voltage of the controller is 3.3 V, the preset voltage threshold can be set to 3.65 V. The first preset power threshold is an empirical value and can be 5% to 15%, for example, 8%, 10%, 12%, etc.

[0046] If the real-time voltage value of the battery cell is lower than the preset voltage threshold and the power value currently displayed by the display component is higher than the first preset power threshold, the display component is controlled to calibrate the currently displayed power value. For example, before controlling the display component to calibrate the currently displayed power value, the power value currently displayed by the display component is 30%, while the actual battery cell voltage is 3.4V. When the user continues to use and inhale, the battery cell voltage will soon be close to the minimum operating voltage of the controller, 3.3V, causing the heating to stop, and thus no aerosol can be inhaled. From the user's perspective, a 30% power value is sufficient to support a very long puffing time, so the power value currently displayed by the display component needs to be calibrated, for example, to 10%, so that the power value currently displayed by the display component is basically consistent with the actual battery cell voltage.

[0047] If the real-time voltage value of the battery cell is higher than the preset voltage threshold or the power value currently displayed by the display component is lower than the first preset power threshold, the display component is controlled to display the current power of the battery cell.

[0048] In one example, the controller is configured to determine the current charge level of the battery cell according to the number of times or duration of the aerosol generating device being inhaled, so as to control the display component to display the current charge level of the battery cell.

[0049] Taking the duration of a puff from the aerosol generating device as an example, a test method can be used to first determine the total duration of the aerosol generating device that can be puffed when the battery cell is fully charged. Then, each time the aerosol generating device is puffed, the duration of that puff is recorded. When the recorded puff duration reaches a certain value, the current battery level displayed on the display component is updated. For example, if the total duration of a puff from the aerosol generating device is 600 seconds, the current battery level displayed on the display component is 100%. When the recorded puff duration reaches 6 seconds, the current battery level displayed on the display component is updated to 99%.

[0050] In one example, the controller is configured to obtain the real-time voltage value of the battery cell and the current power value displayed by the display component when the aerosol generating device is puffed a preset number of times or for a preset duration. Or,

[0051] The controller is configured to obtain the real-time voltage value of the battery cell and the current power value displayed by the display component when the current power value of the battery cell displayed by the display component is lower than a second preset power threshold; wherein the second preset power threshold is greater than the first preset power threshold.

[0052] It is understandable that if the battery cell's power level is high, there is no need to obtain the real-time voltage value of the battery cell and the power level currently displayed by the display component for judgment, that is, to calibrate the power level currently displayed by the display component. Therefore, through this example, the power of the battery cell can be relatively saved.

[0053] In one example, the controller is configured to control the display component to display the battery capacity of the battery cell in a digital manner before controlling the display component to calibrate the currently displayed battery capacity value; when controlling the display component to calibrate the currently displayed battery capacity value, control the display component to display the battery capacity of the battery cell in a non-digital manner.

[0054] The non-digital method includes at least one of Chinese characters, letters, symbols, and graphics. For example, before controlling the display component to calibrate the currently displayed power value, the display component is controlled to display 60%, thereby indicating that the current power level of the battery cell is 60%; when controlling the display component to calibrate the currently displayed power value, the display component is controlled to display LO, thereby indicating that the current power level of the battery cell is low, for example, less than 10%. After this, if the power level of the battery cell continues to decrease, the power level of the battery cell may also be continuously displayed in a non-digital manner. For example, when the power level of the battery cell is less than 10%, the display component is continuously controlled to display LO.

[0055] In one example, the controller is configured to control the power value displayed by the display component to be the first preset power threshold when the real-time voltage value of the battery cell is lower than the preset voltage threshold and the power value currently displayed by the display component is higher than the first preset power threshold.

[0056] For example, assuming the first preset power threshold is 10%, when the display component is calibrated to display a power value of 30%, the display component can be controlled to display a power value of 10%. After that, if the power level of the battery cell continues to decrease, the power level of the battery cell can also be continuously displayed in digital form.

[0057] In one example, the controller is configured to generate a prompt message after controlling the display component to calibrate the currently displayed power value, so as to prompt the user that the power of the battery cell is low.

[0058] By generating the prompt information, the user can be better informed that the power level of the battery cell is low, so that the user can stop smoking and plug in the charger to charge the device in time.

[0059] The prompt information can be transmitted to the user through the display component, and the prompt information can also be transmitted to the user through vibration, sound, etc.

[0060] FIG3 is a schematic diagram of a control method for an aerosol generating device provided in an embodiment of the present application. Specifically, the method includes:

[0061] Step S11, obtaining the real-time voltage value of the battery cell and the current power value displayed by the display component;

[0062] Step S12: When the real-time voltage value of the battery cell is lower than a preset voltage threshold and the power value currently displayed by the display component is higher than a first preset power threshold, control the display component to calibrate the currently displayed power value.

[0063] In one example, the current charge level of the battery cell is determined according to the number of times or duration of the aerosol generating device being puffed, so as to control the display component to display the current charge level of the battery cell.

[0064] In one example, when the aerosol generating device is puffed a preset number of times or for a preset duration, the real-time voltage value of the battery cell and the power value currently displayed by the display component are obtained.

[0065] In one example, when the battery cell power value currently displayed by the display component is lower than a second preset power threshold, the real-time voltage value of the battery cell and the power value currently displayed by the display component are obtained; wherein the second preset power threshold is greater than the first preset power threshold.

[0066] In one example, before controlling the display component to calibrate the currently displayed power value, the display component is controlled to display the power of the battery cell in a digital manner; when controlling the display component to calibrate the currently displayed power value, the display component is controlled to display the power of the battery cell in a non-digital manner.

[0067] In one example, the non-numeric method includes at least one of Chinese characters, letters, symbols, and graphics.

[0068] In one example, when the real-time voltage value of the battery cell is lower than a preset voltage threshold and the power value currently displayed by the display component is higher than a first preset power threshold, the power value displayed by the display component is controlled to be the first preset power threshold.

[0069] In one example, when the real-time voltage value of the battery cell is higher than a preset voltage threshold or the power value currently displayed by the display component is lower than a first preset power threshold, the display component is controlled to display the current power of the battery cell.

[0070] In one example, after controlling the display component to calibrate the currently displayed power value, a prompt message is generated to prompt the user that the power level of the battery cell is low.

[0071] In one example, the preset voltage threshold is greater than a minimum operating voltage of the controller.

[0072] FIG4 is a schematic diagram of the control process of the aerosol generating device provided in an embodiment of the present application. The control process is described in conjunction with the example of FIG1 , and specifically includes:

[0073] Step S21, controlling the aerosol generating device to start heating;

[0074] That is, the battery core 16 is controlled to provide power to the heating element 14 , so that the heating element 14 starts heating the liquid aerosol-forming substrate delivered from the liquid delivery unit 13 .

[0075] Step S22, controlling the display component to display the current power of the battery cell;

[0076] That is, the current charge level of the battery cell 16 is determined according to the number of times or duration of the aerosol generating device being puffed, and the display component 18 is controlled to display the current charge level of the battery cell.

[0077] It should be noted that there is no limitation on the order of steps S21 and S22.

[0078] Step S23: obtaining the real-time voltage value of the battery cell and the current power value displayed by the display component;

[0079] Step S24: determining whether the real-time voltage value of the battery cell is lower than a preset voltage threshold and whether the current power value displayed by the display component is higher than a first preset power threshold;

[0080] For example, determine whether the real-time voltage value of the battery cell 16 is lower than 3.65V and whether the current power value displayed by the display component 18 is higher than 10%; if the real-time voltage value of the battery cell 16 is lower than 3.65V and the current power value displayed by the display component 18 is higher than 10%, execute step S25; otherwise, continue to execute step S22.

[0081] Step S25, controlling the display component to calibrate the currently displayed power value;

[0082] If the real-time voltage value of the battery cell 16 is lower than 3.65V and the current power value displayed by the display component 18 is higher than 10%, the display component 18 is controlled to display LO, indicating that the current power value of the battery cell 16 is lower than 10%.

[0083] Step S26: Generate a prompt message to inform the user that the battery power is low;

[0084] For example, the user is prompted by vibration to indicate that the current power level of the battery cell 16 is low.

[0085] Step S27: determining whether the real-time voltage value of the battery cell is lower than the operating voltage threshold;

[0086] For example, if the real-time voltage value of the battery cell 16 is lower than 3.3V, step S28 is executed; otherwise, the process continues to detect and determine whether the real-time voltage value of the battery cell 16 is lower than the operating voltage threshold, ie, 3.3V.

[0087] Step S28: Control the aerosol generating device to stop heating.

[0088] At this time, the controller is in a stopped working state, and the battery core 16 stops supplying power to the heating element 14, thereby causing the aerosol generating device to stop heating.
