[0023] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be described in further detail below. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0025] Referring to FIG. 1 , an embodiment of the present application provides a control method for an electronic atomization device having multiple heating elements. The control method includes:

[0026] S100, selecting at least one heating element to heat an aerosol-generating substrate at a time according to predetermined parameters of the heating element, wherein the predetermined parameters are used to indicate a usage condition of the heating element;

[0027] Selecting at least one heating element means that one or more heating elements can be selected.

[0028] It should be noted that, in the embodiments of the present application, a plurality includes two and more than two.

[0029] Each heating element has predetermined parameters that indicate its usage. For example, n heating elements are defined as H1 to Hn, where n ≥ 2, and the predetermined parameters are represented by En. During each operation, m of the heating elements are selected for heating, where 1 ≤ m ≤ n.

[0030] S200: After the current heating is completed, the predetermined parameter is updated based on at least one working parameter of the heating element in the current heating.

[0031] After the current heating is completed, at least one working parameter in the current heating needs to be accumulated into the predetermined parameters to update the predetermined parameters for the next heating operation.

[0032] The control method provided in the embodiment of the present application selects at least one heating body to heat the aerosol generating matrix according to the predetermined parameters of the heating body, and updates the predetermined parameters based on at least one working parameter in the current heating, so that the heating body is selected to participate in the heating each time according to the predetermined parameters. That is, the heating body is selected to participate in the heating each time according to the usage of the heating body, instead of all the heating bodies heating the aerosol generating matrix or randomly starting some heating bodies to heat the aerosol generating matrix each time as in the related art, thereby avoiding the problem of serious fouling caused by long-term heating work of some heating bodies, and being able to balance the heating of all heating bodies, thereby avoiding long-term work of some heating bodies, resulting in large differences in performance between the heating bodies and affecting the overall working performance.

[0033] In some embodiments, selecting at least one heating element to heat the aerosol generating substrate based on predetermined parameters of the heating element includes: selecting at least one heating element having the smallest or largest predetermined parameter.

[0034] That is to say, at least one working parameter in the current heating is accumulated into the predetermined parameter, and the accumulation can be accumulation or subtraction.

[0035] Exemplarily, the operating parameter is a positive number. If at least one operating parameter during a heating session is added to a predetermined parameter, then a larger predetermined parameter indicates a greater loss of use of the heating element, and at least one heating element with the smallest predetermined parameter is selected to heat the aerosol-generating substrate. In other words, at least one heating element with the smallest loss of use is selected to heat the aerosol-generating substrate. Conversely, if at least one operating parameter during a heating session is subtracted from the predetermined parameter, then a smaller predetermined parameter indicates a greater loss of use of the heating element, and at least one heating element with the largest predetermined parameter is selected to heat the aerosol-generating substrate.

[0036] In one embodiment, at least one heating element with the smallest predetermined parameter is selected. In other words, at least one heating element with the smallest predetermined parameter is selected from a plurality of heating elements to heat the aerosol generating substrate at the same time.

[0037] Selecting at least one heating element with the smallest predetermined parameter means: selecting a heating element with the smallest predetermined parameter, or selecting multiple heating elements with the smallest predetermined parameter.

[0038] In another embodiment, at least one heating element with the largest predetermined parameter is selected. In other words, at least one heating element with the largest predetermined parameter is selected from a plurality of heating elements to heat the aerosol generating substrate at the same time.

[0039] Selecting at least one heating element with the largest predetermined parameter means: selecting a heating element with the largest predetermined parameter, or selecting multiple heating elements with the largest predetermined parameter.

[0040] By selecting at least one heating element with the smallest or largest predetermined parameter to heat the aerosol generating matrix at that time, and updating the predetermined parameter based on at least one working parameter in that heating, the heating element with the smallest or largest predetermined parameter is selected to participate in the heating each time. In other words, at least one heating element with the smallest loss is selected to heat the aerosol generating matrix, thereby avoiding the problem of serious fouling caused by long-term heating work of some heating elements. The heating of all heating elements can be balanced controlled to avoid long-term work of some heating elements, resulting in large differences in performance between the heating elements and affecting the overall working performance.

[0041] Taking n as 4 as an example, the four heating elements are defined as H1, H2, H3 and H4 respectively. The predetermined parameter corresponding to H1 is E1, the predetermined parameter corresponding to H2 is E2, the predetermined parameter corresponding to H3 is E3, and the predetermined parameter corresponding to H4 is E4. The following example takes the selection of at least one heating element with the smallest predetermined parameter as an example. The specific embodiment is as follows:

[0042] In a specific embodiment, if E2, E3 and E4 are all equal and less than E1, one of H2, H3 and H4 can be selected to heat the aerosol-generating substrate at the same time; two of H2, H3 and H4 can also be selected to heat the aerosol-generating substrate at the same time; and all of H2, H3 and H4 can also be selected to heat the aerosol-generating substrate at the same time.

[0043] In another specific embodiment, if E1, E2, E3 and E4 are all equal, one of H1, H2, H3 and H4 can be selected to heat the aerosol-generating substrate at the same time; two of H1, H2, H3 and H4 can be selected to heat the aerosol-generating substrate at the same time; three of H1, H2, H3 and H4 can be selected to heat the aerosol-generating substrate at the same time; and all of H1, H2, H3 and H4 can be selected to heat the aerosol-generating substrate at the same time.

[0044] In another embodiment, if E2, E3 and E4 are all equal and greater than E1, then H1 may be selected to heat the aerosol generating substrate.

[0045] It should be understood that those skilled in the art can learn specific embodiments of selecting at least one heating element with the largest predetermined parameter based on the examples of the above four specific embodiments, which will not be described in detail here.

[0046] In one embodiment, the initial value of the predetermined parameter of each heating element is equal. The initial value is the value of each heating element before the first heating. In other words, the initial value is the value of the predetermined parameter at an initial moment, where the initial moment is the very first moment, i.e., the moment when time is zero. The initial value of the predetermined parameter of each heating element is equal to facilitate the accumulation of operating parameters.

[0047] In one embodiment, the initial value of the predetermined parameter is zero, that is, the value of each heating element before the first heating is set to 0.

[0048] It is understandable that the initial value of the predetermined parameter may also be other values, for example, the initial value of the predetermined parameter may be 100, etc.

[0049] In one embodiment, the operating parameter includes the electrical power of the heating element during a heating cycle. That is, after the heating cycle is complete, the predetermined parameter is updated based on the electrical power of the heating element during that heating cycle. Thus, the predetermined parameter includes the total electrical power of the heating element. In other words, the predetermined parameter includes the total electrical power of the heating element from the initial operation time to the current time. The total electrical power is used to indicate the usage of the heating element.

[0050] In some embodiments, the electrical power of each heating element includes an average heating power, that is, each heating element has its own average heating power, and the average heating powers of each heating element are independent of each other.

[0051] There is no limitation on the way of obtaining the electric power of the heating. For example, the electric power of the heating can be the average heating power of the heating element multiplied by the working time of the heating element. The average heating power of the heating element can be the average effective voltage of the heating element multiplied by the effective current of the heating element. If the heating element adopts PWM control, the average heating power of the heating element can be the peak power of the heating element multiplied by the duty cycle of PWM. It should be noted that the peak power refers to the power corresponding to the maximum amplitude of the PWM waveform.

[0052] It should be noted that PWM stands for Pulse Width Modulation. The duty cycle of PWM refers to the proportion of the power-on time to the total time within a pulse cycle.

[0053] It should be understood that the average heating power refers to the power per unit time. If the heating element is heated with constant power, the average heating power is Equal to constant power. Constant power means that the power of the heating element remains constant during the heating process, that is, the frequency of work is constant. If the heating element adopts variable power heating, the average heating power This is equal to the total work done during a cycle, e.g., the length of a puff, divided by the cycle time. Variable power refers to the amount of power a heating element produces that changes during the heating process.

[0054] Taking the variable power heating element as an example, the cycle time t=t1+t2+…+tx, and the power of each time period is P1, P2,…Px respectively, then the average heating power is

[0055] It should be noted that during continuous puffing, the user takes multiple puffs, each of which corresponds to one heating of the heating element, and the duration of the user's puffs corresponds to one heating of the heating element. For example, the user's current puff corresponds to the current heating of the heating element.

[0056] For example, in one embodiment, the heating element Hn participates in the heating for the Kth time. When the heating is completed, the predetermined parameter En of the Hn heated for the current time is updated based on the electric power. Specifically, the average heating power of the Hn heated for the current time is calculated as And the working time Tn, and update Among them, En K-1 It is the predetermined parameter of the heating element Hn after it participated in heating for the K-1th time, that is, the last time.

[0057] In some embodiments, the average heating power of each heating element is the same, so that different parts of the aerosol-generating substrate or different aerosol-generating substrates can be heated evenly.

[0058] In other embodiments, the average heating power of each heating element is different. For different parts of the same aerosol generating substrate, such as different areas or different medium segments, the thermal conductivity of each part of the same aerosol generating substrate may be different. Using heating elements with different average heating powers can make the consumption process of each part of the same aerosol generating substrate roughly the same. For different aerosol generating substrates, different aerosol generating substrates may be made of different materials. Since aerosol generating substrates of different materials have different components, different average heating powers can heat and atomize different aerosol generating substrates. In other words, the same electronic atomization device can adapt to aerosol generating substrates of different materials.

[0059] In some other embodiments, the average heating power of each heating element may be partially the same and partially different.

[0060] In one embodiment, under the condition that the average heating power of each heating element is the same, the operating parameter includes the operating time of the heating element during the current heating cycle. Since the average heating power of each heating element is the same, the control method can be simplified, and the predetermined parameter can be calculated by accumulating the operating time of the current heating element, for example, adding them together. In this way, the predetermined parameter includes the total operating time of the heating element. In other words, the predetermined parameter includes the total operating time of the heating element from the initial moment to the present. The total operating time indicates the usage of the heating element.

[0061] Taking the example of the cumulative working time of the heating element Hn as the predetermined parameter, in one embodiment, when the heating element Hn participates in the heating for the Kth time, after the heating is completed, the predetermined parameter En of Hn for the heating is updated based on the working time of the heating. Specifically, since the average heating power of each heating element is the same, the average heating power of Hn for the heating is not calculated, and only the working time Tn of Hn for the heating is calculated, and En is updated to En=En. K-1 +Tn.

[0062] In one embodiment, under the condition that the resistance values ​​of all heating elements are the same, the working parameters include the product of the square of the average effective voltage of the heating element during the heating and the working time of the heating element. The heating element can convert electrical energy into thermal energy. For example, the heating element is a resistive heating structure. Since the resistance values ​​of all heating elements are the same, the predetermined parameters can be simplified to the square of the average effective voltage multiplied by the cumulative working time of the heating element. In this way, the predetermined parameters include the square of the average effective voltage of the heating element multiplied by the value of the working time of the heating element. The usage of the heating element is indicated by multiplying the square of the average effective voltage by the cumulative working time of the heating element.

[0063] It should be understood that the voltage applied to each heating element can be a constant voltage or a variable voltage. The average effective voltage refers to the voltage that produces the same power on the resistance of the heating element during a period of time, such as a puff. If the heating element is heated with a constant voltage, the average effective voltage is Equal to constant voltage. Constant voltage means that the voltage of the heating element remains constant during the heating process. If the heating element is heated by variable voltage, the average effective voltage This is the voltage that produces the same power across the resistance of the heating element during a cycle, such as a puff. Variable voltage refers to the voltage change during the heating process.

[0064] For example, Represents the average effective voltage loaded on each heating element. For the heating element Hn, the resistance value is represented by Rn. The heating element Hn participates in the heating for the Kth time. When the heating is completed, based on Update the predetermined parameter En of the Hn heated at that time. Specifically, under the condition that the resistance values ​​of each heating element are the same, the resistance value Rn of the Hn heated at that time can be calculated without calculating the resistance value Rn of the Hn heated at that time, and only the average effective voltage of the Hn heated at that time can be calculated. And the working time Tn, and update

[0065] In one embodiment, the heating element is controlled by PWM, and the operating parameters include the product of the PWM duty cycle and the current working time. For applications that use PWM to output heating, since the average heating power of the heating element is equal to the peak power of PWM multiplied by the PWM duty cycle, and the peak power of PWM is a constant, En can be simplified to multiply the PWM duty cycle by the cumulative working time. In this way, the predetermined parameters include the value of the PWM duty cycle multiplied by the current working time. The usage of the heating element is indicated by multiplying the PWM duty cycle by the cumulative working time.

[0066] For example, for the heating element Hn, the peak power of PWM is represented by Pn', and the duty cycle of PWM is represented by Dn, then Pn=Pn'*Dn. The heating element Hn participates in the heating for the Kth time. When the heating is completed, the predetermined parameter En of Hn heated for the current time is updated based on Dn*Tn. Specifically, Pn' of Hn heated for the current time can be omitted. Only the duty cycle Dn of Hn heated for the current time and the working time Tn for the current time are calculated, and En=En is updated. K-1 +Dn*Tn.

[0067] Please refer to FIG. 2 . An embodiment of the present application provides a control device 1 . The control device 1 includes a selection module 11 and an update module 12 .

[0068] The selection module 11 is configured to select at least one heating element 1300 to heat the aerosol-generating substrate at a time according to predetermined parameters of the heating element 1300 , wherein the predetermined parameters are used to indicate a usage condition of the heating element 1300 .

[0069] The updating module 12 is configured to update the predetermined parameter based on at least one operating parameter of the heating element 1300 in the heating after the heating is completed.

[0070] Regarding the control device 1 in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the control method and will not be repeated here.

[0071] Please refer to Figure 3. An embodiment of the present application also provides an electronic atomization device 1000, which includes a processor 1100, a memory 1200 and multiple heating elements 1300. The heating elements 1300 are used to heat the aerosol-generating matrix, and the memory 1200 is used to store a computer program that can be run on the processor 1100. When the processor 1100 is used to run the computer program, the steps in the control method of any embodiment of the present application are implemented.

[0072] The aerosol-generating substrate is heated by the heating element 1300 to generate an aerosol. For example, the aerosol-generating substrate can be adapted to generate aerosols using a heat-not-burn method. That is, the aerosol-generating substrate is heated below its ignition point to generate the aerosol. The aerosol-generating substrate does not burn during the aerosol generation process. The electronic atomization device 1000 is configured to allow a user to inhale the aerosol generated by the aerosol-generating substrate.

[0073] The specific type of the electronic atomization device 1000 is not limited. For example, the electronic atomization device 1000 includes but is not limited to an air humidifier, a medical atomizer, or an electronic cigarette, etc.

[0074] The aerosol-forming substrate may be solid or liquid.

[0075] For solid aerosol-generating matrices, the specific instructions are as follows:

[0076] The aerosol-generating matrix may include plant components, auxiliary components, smoke-generating agent components, adhesive components, and the like. The plant components may be one or more combinations of crushed tobacco leaf material, tobacco leaf fragments, tobacco stems, tobacco dust, and flavor plants, resulting in powders. The plant components are used to generate an aerosol containing alkaloids upon heating.

[0077] In one embodiment, the aerosol generating matrix is ​​an integrally molded structure. For example, the aerosol generating matrix can be an integral structure formed by processes such as injection molding, compression molding or extrusion. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the raw material mixture is pushed forward by the screw through the interaction between the extruder barrel and the screw to continuously pass through the die to form various cross-section products or semi-finished products. The aerosol generating matrix formed by extrusion molding is in the shape of strips. In this way, the aerosol generating matrix is ​​an integral medium after being heated and sucked or stopped being heated, and the problem of disintegration and falling is not easy to occur.

[0078] In one embodiment, the aerosol-generating substrate may be substantially in the shape of a column, that is, the aerosol-generating substrate is substantially in the shape of an elongated strip, and the longitudinal length of the aerosol-generating substrate is greater than the distance between any two points on its cross section.

[0079] In a cross section perpendicular to the longitudinal direction of the aerosol-generating substrate, the cross-sectional shape of the aerosol-generating substrate includes, but is not limited to, a circle, an ellipse, a racetrack, or a polygon. For example, if the cross-sectional shape of the aerosol-generating substrate is a circle, the aerosol-generating substrate is roughly cylindrical, and the longitudinal direction of the aerosol-generating substrate is the axial direction of the cylinder.

[0080] In one embodiment, the heating element is located on the periphery of the aerosol-generating matrix. The aerosol-generating matrix is ​​divided into multiple zones along the circumference, with each zone corresponding to a heating element. This allows different heating elements to selectively heat different circumferential zones of the aerosol-generating matrix, selectively releasing aerosol from different parts of the aerosol-generating matrix. This ensures that each puff of aerosol is fresher and has a richer taste.

[0081] In one embodiment, a cavity is formed within the aerosol-generating substrate, and a heating element is located within the cavity. The aerosol-generating substrate is divided into multiple regions along the circumference, each corresponding to a heating element. This allows different heating elements to selectively heat different regions of the aerosol-generating substrate.

[0082] In one embodiment, the aerosol-generating substrate may have multiple dielectric segments along its length, with each dielectric segment corresponding to a heating element, so that different dielectric segments of the aerosol-generating substrate can be selectively heated by different heating elements.

[0083] In one embodiment, each electronic atomization device contains multiple aerosol-generating substrates. In other words, there can be multiple aerosol-generating substrates, each corresponding to a heating element. This allows different heating elements to selectively heat different aerosol-generating substrates.

[0084] For liquid aerosol-generating substrates, the specific instructions are as follows:

[0085] The liquid matrix can be a drug or other substance such as e-liquid. Exemplarily, the liquid matrix includes solvents and additives. Solvents include, but are not limited to, propylene glycol and / or glycerol. Additives can include nicotine salts, plant extracts, and / or flavorings. Flavorings can include flavorings.

[0086] In one embodiment, an electronic atomization device includes a base and a reservoir for storing liquid aerosol-generating substrate. The base includes multiple heating surfaces, each of which is provided with a heating element. The base is capable of directing the liquid aerosol-generating substrate from the reservoir to the heating surface. For example, the base may have a liquid-conducting hole that directs the liquid aerosol-generating substrate to the heating surface. In this way, the aerosol-generating substrate on different heating surfaces can be heated by different heating elements.

[0087] The matrix can be a porous structure. A porous structure refers to a structure having multiple interconnected pores within the structure and connected to the outer surface of the matrix. The pores in a porous structure facilitate both the temporary storage of the liquid matrix and the circulation of the liquid matrix. The multiple pores in the porous structure can be arranged in a disordered manner. In other words, the pores in the porous structure are randomly generated.

[0088] The substrate can be made of ceramic. Ceramic materials have advantages such as good thermal conductivity. For example, the substrate can be made of dense ceramic or porous ceramic. Porous ceramic can be produced by high-temperature sintering of components such as aggregate, binder, and pore-forming agent. During the sintering process, the pore-forming agent creates randomly arranged pores within the porous ceramic.

[0089] It should be noted that in this application, each heating element can be independently controlled. Each heating element can be independently controlled means that each heating element can be turned on, off, or temperature-adjusted, etc. For example, if each heating element is independently powered, independent control of each heating element can be achieved.

[0090] In some embodiments, the heating element may be a resistive heating structure, a heating wire, a heating mesh, or a heating sheet.

[0091] In some embodiments, the electronic atomization device includes a power supply for supplying power to power-requiring devices, such as a heating element. The power supply includes, but is not limited to, a device capable of providing electrical energy, such as a battery. The power supply includes, but is not limited to, a battery. The battery may be a disposable battery or a rechargeable battery.

[0092] In one embodiment, the electronic atomization device includes a main controller, on which both the processor and the memory may be located. The main controller may be used to control the operation of the electronic atomization device, detect the power level of the power supply, and perform other functions. The main controller may also detect the resistance value of the heating element, the voltage applied to the heating element, and / or the operating time of the heating element during a heating cycle.

[0093] The main controller includes but is not limited to an MCU (Microcontroller Unit). The main controller can detect the resistance value of the heating element, the voltage applied to the heating element, and / or the current operating time of the heating element. In this way, operating parameters such as the electric power of the heating element during the current heating can also be obtained through calculation.
