[0002] This application claims priority to Chinese patent application number 2023111709773, filed on September 11, 2023, entitled “Heating control method, readable storage medium, battery assembly and electronic atomization device,” the entire text of which is hereby incorporated by reference.

[0004] Existing electronic atomizers typically consist of an atomizer and a battery assembly. The atomizer contains a heating element, which, driven by the battery, heats the aerosol-generating substrate stored in the atomizer to form an aerosol.

[0065] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0066] The electronic atomization device of the present application is used to heat the aerosol generating matrix to generate an aerosol for the user. The heating method can be convection, conduction, radiation or a combination thereof. The form of the aerosol generating matrix can be a liquid, gel, paste or solid, etc. When the aerosol generating matrix is solid, it can be a solid in the form of crushed, granulated, powdered, granular, strip or sheet. The aerosol generating matrix includes but is not limited to materials used for medical, health, health and beauty purposes, for example, the aerosol generating matrix is a medicinal liquid, oil, or the aerosol generating matrix is a plant material, for example, the roots, stems, leaves, flowers, buds, seeds and the like of plants. That is, the embodiments of the present application do not limit the heating method, form and use of the aerosol generating matrix.
[0067] The multiple atomizing components of the atomizer in the above-mentioned electronic atomizing device are usually loaded with different types of aerosol generating matrices. In order to ensure that each atomizing component has a better heating effect when heating different types of aerosol generating matrices, each heating body is usually required to be connected to a power supply interface that is compatible with it, where these power supply interfaces are usually provided in the battery assembly. However, since the battery assembly and the atomizer are pluggable, when the battery assembly is inserted into the atomizer, the battery assembly may not be accurately inserted into the atomizer (for example, inserted upside down). At this time, each heating body is not accurately connected to the corresponding power supply interface, so it is impossible to ensure that each atomizing component in the atomizer has a good heating effect, thereby affecting the overall heating effect of the atomizer.
[0068] The heating control method provided in the embodiment of the present application can be applied to the electronic atomization device shown in Figure 1. The electronic atomization device includes a battery assembly 102 and an atomizer 104. The atomizer includes multiple atomization assemblies 104A and multiple heating bodies 104B. The multiple atomization assemblies 104A and the multiple heating bodies 104B can correspond one to one, so that each heating body 104B can heat the corresponding heating chamber 104A. The specific number of the multiple atomization assemblies 104A and the multiple heating bodies 104B can be greater than or equal to 2. The battery assembly 102 and the atomizer 104 can be pluggable.
[0069] In this way, when it is detected that the atomizer 104 is connected to the battery assembly 102, the corresponding target heating power will be matched for each heating body 104B according to the heating property information of the heating body 104B corresponding to each atomizer assembly 104A; thereby, according to each target heating power, each heating body 104B can be controlled separately to heat the corresponding atomizer assembly 104A, so that the heating effect of each atomizer assembly can always be at the expected heating effect, thereby improving the overall heating effect of the atomizer composed of multiple atomizer assemblies.
[0070] In one embodiment, as shown in FIG2 , a heating control method is provided, which is described by taking the method applied to the resistive atomization device in FIG1 as an example, including the following steps:
[0071] Step 302: When it is detected that the atomizer is connected to the battery assembly, the corresponding target heating power is matched for each heating body according to the heating property information of the heating body corresponding to each atomizer assembly.
[0072] In this embodiment, there are multiple atomizing components and multiple heating bodies in the atomizer, and the multiple atomizing components and the multiple heating bodies can correspond one to one. The heating body is used to heat the aerosol generating matrix loaded in the atomizing component to generate aerosol.
[0073] As an example, the heating property information is information that affects the heating effect of the heating body when heating the aerosol generating matrix loaded in the atomization component. For example, it can be the resistance value of the heating body or the heating temperature, etc.; the target heating power is the heating power that can enable the heating body to achieve the expected heating effect. The expected heating effect can be the heating time or the final stable heating temperature, etc. For example, the expected heating effect can be that the heating time is within a preset time, or that the final stable heating temperature is within a preset heating temperature range, etc.
[0074] As an example, step 302 includes: when it is detected that the atomizer is connected to the battery assembly, the heating property information of the heating body corresponding to each atomizing assembly in each atomizer is detected; according to the heating property information of each heating body, each heating body is identified separately to obtain a heating body identification result; according to the heating body identification result, the corresponding target heating power is matched for each heating body.
[0075] As an example, the heater identification result may be a heater identification corresponding to each heater. Based on each heater identification, a corresponding target heating power may be matched for each heater.
[0076] Step 304 : Controlling each heating body to heat the atomizer according to each target heating power.
[0077] As an example, step 304 includes: according to each target heating power, by controlling the output voltage of the power supply interface corresponding to each heating body in the battery assembly, respectively controlling each heating body to heat the corresponding atomizing assembly in the atomizer.
[0078] In one embodiment, according to each target heating power, each heating body is controlled to heat the atomizer, including:
[0079] According to the target heating power, the duty cycle of the input voltage corresponding to each heating body is determined; according to each duty cycle, each heating body is controlled to heat the atomizer.
[0080] The duty cycle refers to the proportion of the power-on time to the total time in a pulse cycle. By adjusting the duty cycle of the input voltage of the heater, the heating power of the heater can be adjusted.
[0081] Specifically, based on the target heating power of each heater, the duty cycle of the input voltage corresponding to each heater is calculated. Based on the corresponding duty cycle of each heater, the input voltage of each heater is controlled to control the heating of the atomizer by each heater. This allows the heating power of each heater to be flexibly adjusted without adding additional resistors to the battery assembly. The battery assembly's power supply is not occupied by additional resistors, allowing the heating power of each heater to be flexibly adjusted while ensuring the power supply efficiency of the resistor assembly.
[0082] In the above-mentioned heating control method, after detecting that the atomizer is connected to the battery assembly, the corresponding target heating power will be accurately matched to each heating body according to the heating property information of the heating body corresponding to each atomizer assembly in the atomizer. In this way, even if each heating body is not accurately connected to the corresponding power supply interface, the heating power of each heating body can always be adjusted to the corresponding target heating power. Therefore, according to each target heating power, each heating body is controlled to heat the corresponding atomizer assembly in the atomizer, so that the heating effect of the atomizer assembly corresponding to each heating body can achieve the expected heating effect, thereby improving the overall heating effect of the atomizer composed of multiple atomizer assemblies.
[0083] In one embodiment, as shown in FIG3 , the heating property information includes the resistance value of the heating element, and the method further includes:
[0084] Step 402: Detect the resistance value of each heating element.
[0085] As an example, step 402 includes: after each heating body is connected to the battery assembly, obtaining the heating body voltage and heating body current corresponding to each heating body; and calculating the resistance value of each heating body according to the heating body voltage and heating body current corresponding to each heating body.
[0086] According to the heating property information of the heating body corresponding to each atomizing component, the corresponding target heating power is matched for each heating body, including:
[0087] Step 404 : Identify each heating element according to the resistance value of each resistor to obtain a first heating element identification result.
[0088] As an example, step 404 includes: sorting the heaters according to the resistance values of the respective resistors to obtain a resistance sorting result; and identifying the heaters according to the resistance sorting result to obtain a first heater identification result. For example, the heaters include heater A and heater B, and the resistance value of heater A is greater than the resistance value of heater B. Thus, according to the resistance sorting result, heater A and heater B can be identified among the heaters.
[0089] Step 406 : Matching a corresponding target heating power to each heating body according to the first heating body identification result.
[0090] Among them, the first heating body identification result includes the first identification mark of each heating body, and the first identification mark is an identity mark used to identify the heating body. For example, 0 can be set as the identification mark of heating body A, and 1 can be set as the identification mark of heating body B.
[0091] As an example, step 406 includes: querying the target heating power matched with each heating body according to the first identification identifier of each heating body.
[0092] In this embodiment, by detecting the resistance value of each heating body, when there is a significant difference in the resistance value of each heating body, each heating body can be accurately identified based on the size of each resistance value to obtain a first heating body identification result. Then, based on the first heating body identification result, the corresponding target heating power can be accurately matched for each heating body. In this way, even if each heating body is not accurately connected to the corresponding power supply interface in the battery assembly, each heating body can be accurately identified, thereby accurately matching the corresponding target heating power for each heating body, laying the foundation for ensuring the heating efficiency of each heating body.
[0093] It should be noted that if the types of aerosol generating matrices loaded in each atomization component are different, the specific heat capacities of the aerosol generating matrices loaded in each atomization component will usually be significantly different. This results in that if the initial heating power of each heating body is similar during the heating process, then after heating each atomization component for a period of time, the temperatures of different heating bodies will be significantly different.
[0094] In one embodiment, as shown in FIG4 , the heating property information includes a first heating temperature of the heating body during the heating process; the method further includes:
[0095] Step 502: Detect the first heating temperature of each heating body during the heating process.
[0096] Among them, when the heating body heats the atomizing component, there is a heating process and a stable heating process. During the heating process, the heating body is in a gradually heating state, and the temperature change amplitude of the heating body is greater than the preset change amplitude threshold; during the stable heating process, the temperature of the heating body tends to be constant, or in other words, the temperature change amplitude of the heating body during the stable heating process is less than or equal to the preset change amplitude threshold.
[0097] As an example, a temperature sensor is provided in the electronic atomization device for measuring the first heating temperature of each heating body during the heating process.
[0098] According to the heating property information of the heating body corresponding to each atomizing component, the corresponding target heating power is matched for each heating body, including:
[0099] As an example, step 502 includes: detecting the temperature change amplitude of each heating body. When the temperature change amplitude of each heating body is greater than the preset temperature change amplitude, it is determined that each heating body is in a heating process, and the real-time temperature of each heating body is measured to obtain the first heating temperature of each heating body in the heating process.
[0100] In one embodiment, detecting the first heating temperature of each heating body during the heating process includes:
[0101] Each heating body is controlled to heat the atomizer with a preset heating power; when the heating time meets the preset time, the real-time temperature of each heating body is detected to obtain the first heating temperature of each heating body.
[0102] Among them, when controlling each heating body to heat the atomization component, the temperature of each heating body is initially equal to the ambient temperature. Since the specific heat capacity of the aerosol generating matrix in each atomization component is different, the heating rate of each heating body will be different during the heating process. Therefore, the temperature of each heating body will form obvious differences during the heating process. Finally, each heating body will gradually enter a stable heating process; the preset heating time is used to ensure that each heating body is in the heating process and there is a significant difference in the temperature of each heating body.
[0103] As an example, the preset heating time includes a first heating time and a second heating time, wherein the first heating time is used to ensure that there is a significant difference in the temperature of each heating body, that is, to ensure that there is a significant difference between each heating body after being heated for a sufficiently long time, and the second heating time is used to ensure that each heating body is in a heating process, and the second heating time is less than the heating time taken by the fastest heating body to enter a stable heating process.
[0104] Specifically, each heating element is controlled to heat its corresponding atomizer assembly at a preset heating power. When the heating time is greater than the first heating time and less than the second heating time, the real-time temperature of each heating element is measured and the measured real-time temperature is used as the first heating temperature of the heating element. This ensures that the measured first heating temperatures are the temperatures of each heating element during the heating process, and there are significant differences between the first heating temperatures, thereby ensuring the measurement accuracy of the first heating temperatures of each heating element.
[0105] Step 504 : Identify each heating body according to each first heating temperature to obtain a second heating body identification result.
[0106] As an example, step 504 includes: sorting the heating bodies according to the magnitude of each first heating temperature to obtain a first temperature magnitude sorting result; and identifying the heating bodies according to the first temperature magnitude sorting result to obtain a second heating body identification result. For example, the heating bodies include heating body A and heating body B, heating body A corresponds to a smaller specific heat capacity of the aerosol generating substrate in the atomizing assembly, and heating body B corresponds to a larger specific heat capacity of the aerosol generating substrate in the atomizing assembly. In this way, after controlling the heating bodies to heat for a period of time at the same heating power or a similar heating power, the heating bodies are in a heating process, and the temperatures of the heating bodies are t1 and t2, respectively. If t1 is greater than t2, then because the aerosol generating substrate with a smaller specific heat capacity heats up relatively faster and the aerosol generating substrate with a larger specific heat capacity heats up relatively slower, the heating body at temperature t1 is heating body A, and the heating body at temperature t2 is heating body B. That is, it can be determined which of the heating bodies is heating body A and which is heating body B.
[0107] Step 506 : Matching a corresponding target heating power to each heating body according to the second heating body identification result.
[0108] Among them, the second heating body identification result includes the second identification mark of each heating body, and the second identification mark is an identity mark used to identify the heating body. For example, 0 can be set as the identification mark of heating body A, and 1 can be set as the identification mark of heating body B.
[0109] As an example, step 506 includes: querying the target heating power matched with each heating body according to the second identification identifier of each heating body.
[0110] In this embodiment, by detecting the first heating temperature of each heating body during the heating process, when there is a significant difference in the specific heat capacity of the aerosol generating matrix loaded in the atomization assembly corresponding to each heating body, the heating body corresponding to each atomization assembly can be accurately identified according to the first heating temperature of each heating body, and a second heating body identification result can be obtained. Then, according to the second heating body identification result, the corresponding target heating power can be accurately matched for each heating body. In this way, even if each heating body is not accurately connected to the corresponding power supply interface in the battery assembly, each heating body can be accurately identified, so that the corresponding target heating power can be accurately matched for each heating body, laying the foundation for ensuring the heating efficiency of each heating body.
[0111] It should be noted that when the atomizer reaches the atomization equilibrium state, the heat, thermal radiation energy and heat transfer energy carried away by the vaporization of the aerosol generating matrix in each atomization component are equal to the energy supplied by the heating element. At this time, the temperature change of the heating element is small, and each heating element is in a stable heating process. Each atomization component is usually loaded with different types of aerosol generating matrices. The boiling points of these different types of aerosol generating matrices usually have obvious differences, which will lead to obvious differences in the temperature of the aerosol generating matrix when it is vaporized, and thus the temperature of each heating element during stable heating in the stable heating process is also significantly different.
[0112] In one embodiment, as shown in FIG5 , the heating property information includes a second heating temperature of the heating body when the atomizer reaches an atomization equilibrium state; the method further includes:
[0113] Step 602 : detecting the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state.
[0114] The electronic atomization device may be provided with a temperature sensor for measuring the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state.
[0115] As an example, step 602 includes: detecting whether each atomizing component in the atomizer is in an atomizing equilibrium state; when all are in an atomizing equilibrium state, measuring the real-time temperature of each heating body to obtain a second heating temperature of each heating body when the atomizer reaches an atomizing equilibrium state.
[0116] In one embodiment, detecting the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state includes:
[0117] Detect whether the atomizer is in an atomization equilibrium state; when the atomizer is in an atomization equilibrium state, detect the real-time temperature of each heating body to obtain the second heating temperature of each heating body.
[0118] Specifically, each heating body is controlled to heat its corresponding atomization component, and whether the atomizer is in an atomization equilibrium state is detected in real time during the heating process; when the atomizer is in an atomization equilibrium state, the real-time temperature of each heating body is measured, and the measured real-time temperature is used as the second heating temperature of the heating body.
[0119] In one embodiment, detecting whether the atomizer is in an atomization equilibrium state includes:
[0120] The temperature change amplitude of each heating body during the heating process is obtained; when the temperature change amplitude is less than or equal to the preset temperature change amplitude, it is determined that the atomizer is in an atomization equilibrium state; when the temperature change amplitude is greater than the preset temperature change amplitude, it is determined that the atomizer is not in an atomization equilibrium state.
[0121] Specifically, during the heating process, the temperature variation of each heating element is detected separately; when the temperature variation of each heating element is less than or equal to the preset temperature variation, it indicates that the temperature of each heating element is stable, and the atomizer is determined to have reached the atomization equilibrium state; when the temperature variation of each heating element is not less than or equal to the preset temperature variation, it indicates that the temperature of each heating element is not stable, and the atomizer is determined to have not reached the atomization equilibrium state. In this way, even if the heating elements are controlled to heat with different heating powers, it is possible to determine whether the atomizer has reached the atomization equilibrium state by separately detecting the temperature variation of each heating element, thereby accurately identifying whether the atomizer has reached the atomization equilibrium state.
[0122] As an example, detecting whether the atomizer is in an atomization equilibrium state includes:
[0123] Using a preset heating power, each heating element is controlled to heat its corresponding atomizing component. When the heating time exceeds the preset target heating time, it is determined that each atomizing component in the atomizer is in an atomizing equilibrium state. The preset target heating time is the heating time required for the slowest heating element to enter a stable heating process under the preset power. In this way, by determining the preset target heating time, it is possible to determine whether the atomizer is in an atomizing equilibrium state based on the length of the heating time. There is no need to measure the temperature of the heating element by setting a temperature sensor to detect whether the atomizer is in an atomizing equilibrium state, which helps reduce the structural complexity and cost of the electronic atomizing device.
[0124] According to the heating property information of the heating body corresponding to each atomizing component, the corresponding target heating power is matched for each heating body, including:
[0125] Step 604 : Identify each heating body according to each second heating temperature to obtain a third heating body identification result.
[0126] As an example, step 604 includes: sorting the heating bodies according to the magnitude of each second heating temperature to obtain a second temperature magnitude sorting result; identifying the heating bodies according to the second temperature magnitude sorting result to obtain a third heating body identification result. For example, the heating bodies include heating body A and heating body B, heating body A corresponds to the aerosol generating substrate in the atomizing component with a high boiling point, and heating body B corresponds to the aerosol generating substrate in the atomizing component with a low boiling point. In this way, after the atomizer reaches the atomization equilibrium state, the temperatures of the heating bodies are t1 and t2 respectively, and t1 is greater than t2. Since the temperature of the aerosol generating substrate with a high boiling point is relatively higher after the atomizer reaches the atomization equilibrium state, and the temperature of the aerosol generating substrate with a low boiling point is relatively lower after the atomizer reaches the atomization equilibrium state, the heating body at temperature t1 is heating body A, and the heating body at temperature t2 is heating body B, that is, it can be determined which of the heating bodies is heating body A and which is heating body B.
[0127] Step 606 : Matching a corresponding target heating power to each heating body according to the third heating body identification result.
[0128] Among them, the third heating body identification result includes the third identification mark of each heating body, and the third identification mark is an identity mark used to identify the heating body. For example, 0 can be set as the identification mark of heating body A, and 1 can be set as the identification mark of heating body B.
[0129] As an example, step 606 includes: querying the target heating power matched with each heating body according to the third identification identifier of each heating body.
[0130] In the above embodiment, by detecting the second heating temperature of each heating body when the atomizer reaches atomization equilibrium, the heating body corresponding to each atomization assembly can be accurately identified when there is a significant difference in the boiling point of the aerosol generating matrix loaded in the atomization assembly corresponding to each heating body, and a third heating body identification result can be obtained. Then, based on the third heating body identification result, the corresponding target heating power can be accurately matched for each heating body. In this way, even if each heating body is not accurately connected to the corresponding power supply interface in the battery assembly, each heating body can be accurately identified, thereby accurately matching the corresponding target heating power for each heating body, laying the foundation for ensuring the heating efficiency of each heating body.
[0131] In one embodiment, when it is detected that the atomizer is connected to the battery assembly, the heating property information of the heating body corresponding to each atomizing assembly in each atomizer is detected, wherein the heating property information includes at least one of the resistance value of the heating body, the first heating temperature of the heating body during the heating process, and the second heating temperature of the heating body when the atomizer reaches an atomization equilibrium state; based on the heating property information of each heating body, each heating body is identified respectively to obtain a heating body identification result; based on the heating body identification result, a corresponding target heating power is matched for each heating body.
[0132] After matching the target heating power for each heater, the duty cycle of the input voltage corresponding to each heater is calculated based on the target heating power of each heater. Based on the corresponding duty cycle of each heater, the input voltage of each heater is controlled to control the heating of the atomizer by each heater. This allows the heating power of each heater to be flexibly adjusted without adding additional resistors to the battery assembly. The power supply of the battery assembly will not be occupied by the additional resistors, and the power supply efficiency of the resistor assembly can be guaranteed while the heating power of each heater can be flexibly adjusted.
[0133] In the above embodiment, even if each heating body is not accurately connected to the corresponding power supply interface, the heating power of each heating body can always be adjusted to the corresponding target heating power, so that according to each target heating power, each heating body is controlled to heat the corresponding atomizing component in the atomizer, so that the heating effect of the atomizing component corresponding to each heating body can achieve the expected heating effect, thereby improving the overall heating effect of the atomizer composed of multiple atomizing components.
