DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The electronic atomization device of the present application is used to heat the aerosol generating matrix to generate aerosol for the user to use. The heating method can be convection, conduction, radiation or a combination thereof. The form of the aerosol generating matrix can be 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 a substance used for medical treatment, health preservation, health, beauty, etc. The target material, for example, the aerosol generating substrate is a liquid medicine, oil, or the aerosol generating substrate is a plant material, for example, plant roots, stems, leaves, flowers, buds, seeds, etc. That is, the embodiments of the present application do not limit the heating method, form, and use of the aerosol generating substrate.

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 make each atomizing component have 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 compatible with it, wherein these power supply interfaces are usually arranged on the battery assembly, but because 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), and 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.

The heating control method provided in the embodiment of the present application can be applied to the electronic atomization device as shown in FIG1 . The electronic atomization device includes a battery assembly 102 and an atomizer 104, and the atomizer includes a plurality of atomization assemblies 104A and a plurality of heating bodies 104B, wherein the plurality of atomization assemblies 104A and the plurality of heating bodies 104B can correspond one to one, so that each heating body 104B can heat the corresponding heating chamber 104A, and the specific number of the plurality of atomization assemblies 104A and the plurality of heating bodies 104B can be greater than or equal to 2, and the battery assembly 102 and the atomizer 104 can be pluggable.

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 to heat the corresponding atomizer assembly 104A, so that the heating effect of each atomizer assembly can always be at the expected heating effect, which can improve the overall heating effect of the atomizer composed of multiple atomizer assemblies.

In one embodiment, as shown in FIG. 2 , a heating control method is provided, which is described by taking the method applied to the resistance atomization device in FIG. 1 as an example, and includes the following steps:

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.

Among them, 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 an aerosol.

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 may be the resistance value or heating temperature of the heating body. The target heating power is the heating power that can enable the heating body to achieve the expected heating effect. The expected heating effect may be the heating time or the final stable heating temperature. For example, the expected heating effect may be the heating time within a preset time, or the final stable heating temperature within a preset heating temperature range.

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 respectively 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.

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.

Step 304: Control each heating body to heat the atomizer according to each target heating power.

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.

In one embodiment, according to each target heating power, each heating body is controlled to heat the atomizer, including:

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.

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.

Specifically, according to the target heating power of each heating body, the duty cycle of the input voltage corresponding to each heating body is calculated respectively; according to the duty cycle corresponding to each heating body, the input voltage of each heating body is controlled respectively to control each heating body to heat the atomizer. In this way, the heating power of each heating body can be flexibly adjusted without connecting an additional resistor to the battery assembly, and the power supply power of the battery assembly will not be occupied by the additional resistor. The power supply efficiency of the resistor assembly can be guaranteed while the heating power of each heating body can be flexibly adjusted.

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 for 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.

In one embodiment, as shown in FIG3 , the heating property information includes the resistance value of the heating body, and the method further includes:

Step 402, detecting the resistance value of each heating body.

As an example, step 402 includes: after each heater is connected to the battery assembly, obtaining the heater voltage and heater current corresponding to each heater; and calculating the resistance value of each heater according to the heater voltage and heater current corresponding to each heater.

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:

Step 404, identifying each heating body according to the resistance value of each resistor, and obtaining a first heating body identification result.

As an example, step 404 includes: sorting the heaters according to the resistance values of the resistors to obtain a resistance sorting result; identifying the heaters according to the resistance sorting result to obtain a first heater identification result. For example, the heaters include a heater A and a heater B, and the resistance value of the heater A is greater than the resistance value of the heater B. Thus, according to the resistance sorting result, it is possible to determine which heater A and which heater B are among the heaters.

Step 406 : According to the first heating body identification result, the corresponding target heating power is matched for each heating body.

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.

As an example, step 406 includes: querying the target heating power matched by each heating body according to the first identification mark of each heating body.

In the present 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 according to the size of each resistance value to obtain a first heating body identification result, and then according to 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.

It should be noted that if the types of aerosol generating substrates loaded in each atomization component are different, the specific heat capacity of the aerosol generating substrates 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 temperature of different heating bodies will be significantly different.

In one embodiment, as shown in FIG. 4 , the heating property information includes a first heating temperature of the heating body during the heating process; the method further includes:

Step 502, detecting the first heating temperature of each heating body during the heating process.

Among them, when the heating body heats the atomizing component, there is a heating process and a stable heating process. In 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.

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.

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:

As an example, step 502 includes: detecting the temperature change amplitude of each heating body, and when the temperature change amplitude of each heating body is greater than the preset temperature change amplitude, determining that each heating body is in a heating process, and measuring the real-time temperature of each heating body to obtain the first heating temperature of each heating body in the heating process.

In one embodiment, detecting the first heating temperature of each heating body during the heating process includes:

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.

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 speed 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 that there is a significant difference in the temperature of each heating body.

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 fastest heating time for each heating body to enter a stable heating process.

Specifically, with a preset heating power, each heating body is controlled to heat the corresponding atomizing assembly; 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 body is measured, and the real-time temperature measured at this time is used as the first heating temperature of the heating body. In this way, it can be ensured that the measured first heating temperatures are the temperatures of each heating body during the heating process, and there are obvious differences between the first heating temperatures, thereby ensuring the measurement accuracy of the first heating temperatures of each heating body.

Step 504 , identifying each heating body according to each first heating temperature, and obtaining a second heating body identification result.

As an example, step 504 includes: sorting each heating body according to the size of each first heating temperature to obtain a first temperature size sorting result; identifying each heating body according to the first temperature size sorting result to obtain a second heating body identification result. For example, each heating body includes a heating body A and a heating body B, and the specific heat capacity of the aerosol generating matrix corresponding to the heating body A in the atomization component is small, and the specific heat capacity of the aerosol generating matrix corresponding to the heating body B in the atomization component is large. In this way, after each heating body is controlled to heat for a period of time with the same heating power or a similar heating power, each heating body is in a heating process, and the temperature of each heating body is t1 and t2 respectively, and t1 is greater than t2. Because the aerosol generating matrix with a small specific heat capacity heats up relatively faster, and the aerosol generating matrix with a large specific heat capacity heats up relatively slower, the heating body with a temperature of t1 is heating body A, and the heating body with a temperature of t2 is heating body B, that is, it can be determined which is heating body A and which is heating body B among the heating bodies.

Step 506 : According to the second heating body identification result, the corresponding target heating power is matched for each heating body.

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.

As an example, step 506 includes: querying the target heating power matched by each heating body according to the second identification mark of each heating body.

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 substrate loaded in the atomizing assembly corresponding to each heating body, the heating body corresponding to each atomizing 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. The thermal body identification results can accurately match the corresponding target heating power 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.

It should be noted that when the atomizer reaches an 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. Different types of aerosol generating matrices are usually loaded in each atomization component. The boiling points of these different types of aerosol generating matrices usually differ significantly, which leads to significant 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 also differs significantly.

In one embodiment, as shown in FIG. 5 , 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:

Step 602, detecting the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state.

Among them, a temperature sensor may be provided in the electronic atomization device for measuring the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state.

As an example, step 602 includes: detecting whether each atomization component in the atomizer is in an atomization equilibrium state. If they are in an atomization 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 atomization equilibrium state.

In one embodiment, detecting the second heating temperature of each heating body when the atomizer reaches an atomization equilibrium state includes:

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.

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.

In one embodiment, detecting whether the atomizer is in an atomization equilibrium state includes:

The temperature variation amplitude of each heating body during the heating process is obtained; when the temperature variation amplitude is less than or equal to the preset temperature variation amplitude, it is determined that the atomizer is in an atomization equilibrium state; when the temperature variation amplitude is greater than the preset temperature variation amplitude, it is determined that the atomizer is not in an atomization equilibrium state.

Specifically, during the heating process, the temperature variation of each heating body is detected separately; when the temperature variation of each heating body is less than or equal to the preset temperature variation, it means that the temperature of each heating body is in a stable state, and it is determined that the atomizer has reached the atomization equilibrium state; when the temperature variation of each heating body is not less than or equal to the preset temperature variation, it means that the temperature of each heating body is not in a stable state, and it is determined that the atomizer has not reached the atomization equilibrium state. In this way, even if the heating body is controlled to heat with different heating powers, it is possible to determine whether the atomizer has reached the atomization equilibrium state by detecting the temperature variation of each heating body separately, and accurate identification of whether the atomizer has reached the atomization equilibrium state can be achieved.

As an example, detecting whether the atomizer is in an atomization equilibrium state includes:

With the preset heating power, each heating body is controlled to heat the corresponding atomization component. When the heating time exceeds the preset target heating time, it is determined that each atomization component in the atomizer is in an atomization equilibrium state, wherein the preset target heating time is the slowest heating time of each heating body entering a stable heating process under the preset power. In this way, by determining the preset target heating time, it is possible to judge whether the atomizer is in an atomization equilibrium state based on the length of the heating time. There is no need to measure the temperature of the heating body by setting a temperature sensor to detect whether the atomizer is in an atomization equilibrium state, which helps to reduce the structural complexity of the electronic atomization device and reduce the cost of the electronic atomization device.

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:

Step 604: Identify each heating body according to each second heating temperature to obtain a third heating body identification result.

As an example, step 604 includes: sorting the heating bodies according to the magnitude of the second heating temperatures to obtain the second temperature magnitude sorting result; identifying the heating bodies according to the second temperature magnitude sorting result to obtain the third Heating body identification result. For example, each heating body includes heating body A and heating body B. Heating body A corresponds to the high boiling point of the aerosol generating substrate in the atomization component, and heating body B corresponds to the low boiling point of the aerosol generating substrate in the atomization component. In this way, after the atomizer reaches the atomization equilibrium state, the temperatures of each heating body are t1 and t2 respectively, and t1 is greater than t2. Because 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 is heating body A and which is heating body B among the heating bodies.

Step 606: Match the corresponding target heating power for each heating body according to the third heating body identification result.

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.

As an example, step 606 includes: querying the target heating power matched by each heating body according to the third identification mark of each heating body.

In the above embodiment, by detecting the second heating temperature of each heating body when the atomizer reaches atomization equilibrium, 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, the heating body corresponding to each atomization assembly can be accurately identified to obtain a third heating body identification result, and then according to the third heating body identification result, the corresponding target heating power can be accurately matched for each heating body.
