At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0052] In one embodiment, a power supply device for an aerosol generating device is provided, and the power supply device can be used to power the aerosol generating device. Figure 1 As shown, the aerosol generating device 100 includes a first atomizing chamber 110, a second atomizing chamber 120, a first heating assembly 130, and a second heating assembly 140. The first atomizing chamber 110 and the second atomizing chamber 120 are respectively used to atomize the aerosol generating substrate; the first heating assembly 130 is used to heat the aerosol generating substrate in the first atomizing chamber 110, and the second heating assembly 140 is used to heat the aerosol generating substrate in the second atomizing chamber 120.

[0053] The first atomizing chamber 110 and the second atomizing chamber 120 are isolated from each other, and the user can atomize the same type of aerosol-generating substrate or different types of aerosol-generating substrates in the first atomizing chamber 110 and the second atomizing chamber 120 according to actual needs. The first heating component 130 and the second heating component 140 can be heated simultaneously or independently, and the heating powers of the first heating component 130 and the second heating component 140 can be the same or different. For example, the user can atomize aerosol generating matrix A in the first atomizing chamber 110, and atomize aerosol generating matrix B in the second atomizing chamber 120. By making the first heating component 130 work alone, aerosol A obtained by atomizing aerosol generating matrix A can be obtained; by making the second heating component 140 work alone, aerosol B obtained by atomizing aerosol generating matrix B can be obtained; by making the first heating component 130 and the second heating component 140 work at the same time, a mixture of aerosol A and aerosol B can be obtained; by adjusting the heating power of the first heating component 130 and the second heating component 140, the mixing ratio and state of the mixture of aerosol A and aerosol B can be adjusted.

[0054] In actual use, the first heating component 130 and the second heating component 140 can be powered by an external power supply device, or a power supply module with a power supply function can be provided in the aerosol generating device 100 as needed. It can be understood that the aerosol generating device 100 can also include a liquid storage chamber, a glass fiber tube, a heating bracket, an inner cotton bag, etc. The liquid storage chamber is used to store the aerosol generating matrix, one end of the glass fiber tube is connected to the aerosol outlet airflow, and the other end is sleeved on the upper end of the heating bracket. The glass fiber tube forms an atomization channel. When the first heating component 130 and / or the second heating component 140 is heated, the aerosol formed by the aerosol generating matrix flows through the glass fiber tube through the aerosol outlet to be provided to the user. It should be noted that the aerosol generating device 100 is not limited to the above structure. Those skilled in the art can refer to the commonly used technology in the field for setting, and only need to realize the above corresponding functions.

[0055] The first atomizing chamber 110 and the second atomizing chamber 120 in the above-mentioned aerosol generating device can atomize two different types of aerosol generating substrates, so that when the first heating component 130 is heated, the aerosol generating substrate in the first atomizing chamber 110 generates a first type of aerosol; when the second heating component 140 is heated, the aerosol generating substrate in the second atomizing chamber 120 generates a second type of aerosol; when the first heating component 130 and the second heating component 140 are heated at the same time, the aerosols generated in the two atomizing chambers can form a mixed aerosol. This enriches the types of aerosols provided to users and meets the needs of users for different types of aerosols.

[0056] In one embodiment, Figure 2As shown, the power supply device 200 includes an energy storage module 210, a controller 220, and a heating control circuit 230 connecting the energy storage module 210 and the controller 220. The heating control circuit 230 is also used to connect the first heating component 130 and the second heating component 140. The controller 220 is used to control the heating control circuit 230 to supply power to the first heating component 130 and / or the second heating component 140, so that the first heating component 130 generates heat and / or the second heating component 140 generates heat.

[0057] Among them, the energy storage module 210 can be set according to actual needs, for example, it is a device that can store and output electrical energy, such as a battery cell or a battery. The controller 220 may include a processor such as an MCU (Microcontroller Unit) and adaptive peripheral circuits. In actual implementation, the controller 220 may also include an interactive module. After the user inputs a heating control instruction through the interactive module, the controller 220 can analyze the aerosol type information according to the heating control instruction, and then perform subsequent analysis and processing to control the heating control circuit 230 to supply power to the corresponding heating component.

[0058] The power supply device 200 of the above-mentioned aerosol generating device, since the first atomizing chamber 110 and the second atomizing chamber 120 in the aerosol generating device 100 can atomize two different types of aerosol generating substrates, the controller 200 in the power supply device 200 can control the heating control circuit 230 to supply power to the first heating component 130 and / or the second heating component 140, so that the first heating component 130 generates heat and / or the second heating component 140 generates heat. Thus, when the first heating component 130 is heated, the aerosol generating substrate in the first atomizing chamber 110 generates a first aerosol; when the second heating component 140 is heated, the aerosol generating substrate in the second atomizing chamber 120 generates a second aerosol; when the first heating component 130 and the second heating component 140 are heated at the same time, the aerosols generated in the two atomizing chambers can form a mixed aerosol. Thereby, the types of aerosols provided to users are enriched, and the needs of users for different types of aerosols are met.

[0059] Furthermore, when the power supply device 200 is in use, it can also realize the control function of heating the first heating component 130 and the second heating component 140 at different times, such as making the aerosol generating matrix in the first atomizing chamber 110 atomize into a first aerosol first, and after a period of time, the aerosol generating matrix in the second atomizing chamber 120 atomizes into a second aerosol, thereby making the mixed aerosol richer.

[0060] In one embodiment, Figure 3As shown, the first heating component 130 and the second heating component 140 in the aerosol generating device 100 are connected, and the controller 220 realizes the first heating component 130 and the second heating component 140 working in series or in parallel when controlling the heating control circuit 230 to supply power to the first heating component 130 and the second heating component 140.

[0061] Specifically, when the first heating component 130 and the second heating component 140 need to work at the same time, and the first resistance value of the first heating component 130 and the second resistance value of the second heating component 140 do not meet the series heating condition, the controller 220 controls the heating control circuit 230 to supply power to the first heating component 130 and the second heating component 140 respectively, so that the first heating component 130 and the second heating component 140 work in parallel. When the series heating condition is met between the first resistance value and the second resistance value, the controller 220 controls the heating control circuit 230 to supply power to the circuit in which the first heating component 130 and the second heating component 140 are connected in series, so that the first heating component 130 and the second heating component 140 work in series.

[0062] It can be understood that when the first heating component 130 heats the aerosol generating substrate A in the first atomizing chamber 110 and the second heating component 140 heats the aerosol generating substrate B in the second atomizing chamber 120, the first target heating power of the first heating component 130 and the second target heating power of the second heating component 140 need to be set in combination with the aerosol generating substrate A and the aerosol generating substrate B. When the difference between the ratio between the first resistance value and the second resistance value and the ratio between the first target heating power and the second added power is within a preset range, it is considered that the first resistance value and the second resistance value meet the series heating condition. Among them, the preset range needs to be set in combination with the actual situation, and this embodiment does not limit this.

[0063] When the first heating component 130 and the second heating component 140 work in series, the resistance in the circuit is the largest and the current is the smallest. At this time, the energy consumption of the peripheral resistance in the circuit (such as the internal resistance of the battery cell, the internal resistance of the transistor in the heating control circuit 230, the contact resistance, etc.) is minimal, thereby improving the utilization rate of the battery cell power.

[0064] In one embodiment, Figure 4 As shown, the heating control circuit 230 includes a power supply control circuit 231 and a parallel grounding control switch 232 respectively connected to the energy storage module 210, and the power supply control circuit 231 and the parallel grounding control switch 232 are also respectively connected to the controller 220. The power supply control circuit 231 is connected to the first end of the first heating component 130 and the first end of the second heating component 140, and the second end of the first heating component 130 and the second end of the second heating component 140 are both grounded through the parallel grounding control switch 232.

[0065] The parallel grounding control switch 232 may be grounded to the negative electrode of the energy storage module 210. Specifically, the power supply control circuit 231 may be connected to the positive electrode of the energy storage module 210 (such as a battery cell), and the parallel grounding control switch 232 may be connected to the negative electrode of the energy storage module 210, so that the controller 220 can supply power to the first heating component 130 alone, or supply power to the second heating component 140 alone, or supply power to both the first heating component 130 and the second heating component 140 at the same time by controlling the power supply control circuit 231 and the parallel grounding control switch 232 accordingly.

[0066] Furthermore, if Figure 5 As shown, the heating control circuit 230 also includes a series grounding control switch 233, which is respectively connected to the energy storage module 210 and the controller 220; the first end of the first heating component 130 or the first end of the second heating component 140 is also grounded through the series grounding control switch 233.

[0067] exist Figure 5 In the illustrated embodiment, the first end of the second heating component 140 is connected to the ground GND through the series grounding control switch 233. Thus, the power supply control circuit 231, the first heating component 130, the second heating component 140 and the series grounding control switch 233 constitute a series power supply loop, so that the first heating component 130 and the second heating component 140 work in series. In actual implementation, it can also be set that the first end of the first heating component 130 is grounded through the series grounding control switch 233, and the power supply control circuit 231, the second heating component 140, the first heating component 130 and the series grounding control switch 233 connected to the first end of the first heating component 130 constitute a series power supply loop, so that the first heating component 130 and the second heating component 140 can also work in series. It can be understood that the ground GND connected to the parallel grounding control switch 232 and the series grounding control switch 233 can be the negative electrode of the energy storage module 210.

[0068] In one embodiment, Figure 6 As shown, the power supply control circuit 231 includes two groups of power supply switch units 2311, the control ends of the two groups of power supply switch units 2311 are connected to the controller 220, the first ends of the two groups of power supply switch units 2311 are connected to the energy storage module 210, the second end of one group of power supply switch units 2311 is connected to the first end of the first heating component 130, and the second end of the other group of power supply switch units 2311 is connected to the first end of the second heating component 140.

[0069] exist Figure 6 In the illustrated embodiment, the number of energy storage modules 210 is two for the sake of illustration, and an appropriate number may be set according to actual needs during implementation.

[0070] The first ends of the two groups of power supply switch units 2311 are connected to the positive electrode of the energy storage module 210, so that one group of power supply switch units 2311, the first heating component 130, and the parallel grounding control switch 232 constitute the power supply circuit of the first heating component 130; the other group of power supply switch units 2311, the second heating component 140, and the parallel grounding control switch 232 constitute the power supply circuit of the second heating component 140; the two groups of power supply switch units 2311, the first heating component 130, the second heating component 140, and the parallel grounding control switch 232 constitute a parallel power supply circuit; the power supply switch unit 2311 connected to the first end of the first heating component 130, the first heating component 130, the second heating component 140, and the series grounding control switch 233 constitute a series power supply circuit. Therefore, the power supply device 200 can realize the individual control, series control, and parallel control of the first heating component 130 and the second heating component 140, and the control mode can be adjusted according to the actual situation, and the control is more flexible, so that the aerosol generating device can generate more types of aerosols.

[0071] The structures of the power supply switch unit 2311, the parallel grounding control switch 232 and the series grounding control switch 233 can be set according to actual needs. Figure 7 As shown, the power switch unit 2311 includes a transistor Q1, a resistor R1 and a resistor R2, the first end of the transistor Q1 is connected to the first end of the resistor R1; the gate of the transistor Q1 is connected to the second end of the resistor R1 and the first end of the resistor R2 respectively; the second end of the resistor R2 serves as the control end of the power switch unit 2311 and is connected to the controller 220. The first end of the transistor Q1 serves as the first end of the power switch unit 2311 and is connected to the positive electrode of the control module 210. The second end of the transistor Q1 serves as the second end of the power switch unit 2311.

[0072] The parallel ground control switch 232 includes a transistor Q2 and a resistor R3, wherein the first end of the transistor Q2 is used to connect the second end of the first heating component 130 and the second end of the second heating component 140, the second end of the transistor Q2 is grounded, and the gate of the transistor Q2 is connected to the controller 220 via the resistor R3.

[0073] The series grounding control switch 233 includes a transistor Q3 and a resistor R4, wherein the first end of the transistor Q3 is used to connect the first end of the first heating component 130 or the first end of the second heating component 140, the second end of the transistor Q3 is grounded, and the gate of the transistor Q3 is connected to the controller 220 via the resistor R4.

[0074] In one embodiment, the power supply device 200 also includes three connecting components; the power supply control circuit 231 is connected to the first end of the first heating component 130 through the first connecting component, the power supply control circuit 231 is connected to the first end of the second heating component 140 through the second connecting component, and the ground control switch 232 is connected to the second end of the first heating component 130 and the second end of the second heating component 140 through the third connecting component.

[0075] In actual use, three connection components are used to electrically connect the power supply device 200 and the aerosol generating device 100. The connection components may be ejector pins, and further, elastic ejector pins may be used.

[0076] In one embodiment, Figure 8 As shown, the first end of the second heating component 140 is grounded through a series grounding control switch 233, and the power supply device 200 also includes a first resistance detection circuit 241 connected to the controller 220 and the energy storage module 210 respectively; the first resistance detection circuit 241 is also used to connect the first end of the first heating component 130. After the controller 220 controls the power supply control circuit 231 to stop supplying power, the resistance of the first heating component 130 and the second heating component 140 is detected by the first resistance detection circuit 241.

[0077] Specifically, after the power supply control circuit 231 stops supplying power, the first resistance detection circuit 241 can detect the first resistance of the first heating component 130 by connecting the ground control switch 232 in parallel, and detect the total resistance of the first heating component 130 and the second heating component 140 in series by connecting the ground control switch 233 in series, and then obtain the second resistance of the second heating component 140 by the total resistance and the first resistance, thereby realizing the detection of the resistance of the two heating components. Then, the controller 220 can determine the power supply parameters output to the first heating component 130 and the second heating component 140 according to the first resistance and the second resistance. Furthermore, the controller 220 can also determine whether the first heating component 130 and the second heating component 140 can be controlled to work in series based on the relationship between the first resistance and the second resistance, so as to improve the utilization rate of the energy storage module 210.

[0078] In one embodiment, Fig. 9 As shown, the power supply device 200 further includes a second resistance detection circuit 242 connected to the controller 220 and the energy storage module 210 respectively; the second resistance detection circuit 242 is also used to connect to the first end of the second heating component 140. After the controller 220 controls the power supply control circuit 231 to stop supplying power, the resistance of the first heating component 130 is detected by the first resistance detection circuit 241, and the resistance of the second heating component 140 is detected by the second resistance detection circuit 242.

[0079] In this embodiment, by adding a set of resistance detection circuits, separate detection of the first heating component 130 and the second heating component 140 is achieved, which facilitates rapid control of the controller 220.

[0080] The structures of the first resistance detection circuit 241 and the second resistance detection circuit 242 can be set according to actual needs. Fig.10 As shown, the first resistance detection circuit 241 includes a transistor Q4, a resistor R5, a resistor R6 and a resistor R7, the first end of the transistor Q4 is connected to the positive electrode of the energy storage module 210, the first end of the transistor Q4 is connected to the gate of the transistor Q4 through the resistor R5, the gate of the transistor Q4 is also connected to the controller 220 through the resistor R6, and the second end of the transistor Q4 is connected to the first end of the first heating component 130 through the resistor R7. The second resistance detection circuit 242 includes a transistor Q5, a resistor R8, a resistor R9 and a resistor R10, the first end of the transistor Q5 is connected to the positive electrode of the energy storage module 210, the first end of the transistor Q5 is also connected to the gate of the transistor Q5 through the resistor R8, the gate of the transistor Q5 is also connected to the controller 220 through the resistor R9, and the second end of the transistor Q5 is connected to the first end of the second heating component 140 through the resistor R10.

[0081] Those skilled in the art will appreciate that the type of the transistor can be selected based on actual conditions, and the first and second ends of the transistor also need to be determined based on the specific type of the transistor. Fig. 9 The embodiment shown here illustrates the principle of the power supply device 200:

[0082] When the first heating component 130 and the second heating component 140 are heated in parallel, the controller 220 controls transistors Q4 and Q5 to be turned off through ports GPIOA and GPIOB, controls transistor Q2 to be turned on through port GPIOC, controls transistor Q3 to be turned off through port GPIOD, and controls the power supply parameters provided to the first heating component 130 by outputting a PWM1 signal, and controls the power supply parameters provided to the second heating component 140 by outputting a PWM2 signal, thereby respectively controlling the heating of the first heating component 130 and the second heating component 140. Among them, the PWM1 control signal and the PWM2 control signal are both PWM (pulse width modulation) signals, and the change of their duty cycle can change the amplitude of the voltage output by Q1.

[0083] When the first heating component 130 and the second heating component 140 are heated in series, the controller 220 controls transistors Q4 and Q5 to be turned off through ports GPIOA and GPIOB, controls transistor Q2 to be turned off through port GPIOC, controls transistor Q3 to be turned on through port GPIOD, and controls transistor Q1 connected to the first end of the second heating component 140 to be turned off, and controls transistor Q1 connected to the first end of the first heating component 130 to work by outputting a corresponding PWM1 signal, thereby controlling the first heating component 130 and the second heating component 140 to be heated in series.

[0084] When parallel resistance measurement is implemented, the controller 220 controls the two sets of transistors Q1 to be turned off, controls transistor Q2 to be turned on through port GPIOC, controls transistor Q3 to be turned off through port GPIOD, and controls transistor Q4 and transistor Q5 to be turned on through port GPIOA and port GPIOB. At this time, the controller 220 can respectively measure the resistance values ​​of the first heating component 130 and the second heating component 140 through port ADC1 and port ADC2. Port ADC1 and port ADC2 are interfaces for converting analog signals of ADC (Analog-to-Digital Converter) into digital signals.

[0085] When measuring the resistance in series, the controller 220 controls the two sets of transistors Q1 to be turned off, controls the transistor Q2 to be turned on through the port GPIOC, controls the transistor Q3 to be turned off through the port GPIOD, controls the transistor Q4 to be turned on through the port GPIOA, and controls the transistor Q5 to be turned off through the port GPIOB. At this time, the controller 220 can measure the first resistance of the first heating component 130 through the port ADC1. Next, the controller 220 controls the transistor Q2 to be turned off through the port GPIOC, and controls the transistor Q3 to be turned on through the port GPIOD. At this time, the total resistance of the first heating component 130 and the second heating component 140 can be measured through the port ADC1, and then the resistance of the second heating component 140 can be obtained by calculation.

[0086] It can be understood that after obtaining the resistance values ​​of the first heating component 130 and the second heating component 140 , the controller 220 can achieve the purpose of constant power output control by controlling the duty ratio of the PWM1 signal and the PWM2 signal.

[0087] The power supply device 200 of the aerosol generating device can realize real-time independent detection of the resistance values ​​of the first heating component 130 and the second heating component 140. On the one hand, it can realize independent control of the two heating components; on the other hand, when conditions permit, it can reduce useless consumption as much as possible and improve the utilization rate of the battery cell through series power supply control. When series power supply is not possible, the two heating components can still be controlled to work simultaneously by parallel power supply. On the basis of satisfying the power supply control of the aerosol generating device, the power supply method is more flexible.

[0088] In one embodiment, an electronic atomization device is further provided, comprising a power supply device 200 of the aerosol generating device as described in the above embodiments.

[0089] In one embodiment, a control method for a power supply device of an aerosol generating device is further provided. The control method is implemented based on the power supply device 200 of the aerosol generating device of each of the above embodiments. Figure 2 The controller 220 in FIG. 1 is used as an example to illustrate. Fig.11 As shown, the control method includes the following steps 300 and 400.

[0090] Step 300, obtaining a heating control instruction.

[0091] The heating control instruction may include aerosol type information, and the controller can analyze and obtain the aerosol type information according to the heating control instruction.

[0092] Step 400, according to the heating control instruction, control the heating control circuit to supply power to the first heating component and / or the second heating component, so that the first heating component generates heat and / or the second heating component generates heat.

[0093] The controller can analyze and obtain aerosol type information according to the heating control instruction, and perform subsequent analysis and processing to control the heating control circuit to supply power to the corresponding heating component.

[0094] The control method can realize the independent power supply and the simultaneous power supply to the two heating components, thereby enriching the types of aerosols generated in the two atomization chambers in the aerosol generating device and meeting the user's needs for different types of aerosols.

[0095] In one embodiment, the first heating element and the second heating element are connected ， The power supply device also includes a first resistance detection circuit connected to the controller and the energy storage module respectively; the first resistance detection circuit is also used to connect the first heating component; in step 400, controlling the heating control circuit to supply power to the first heating component and the second heating component includes:

[0096] Obtaining a first resistance value of the first heating component and a second resistance value of the heating component;

[0097] If the series heating condition is satisfied between the first resistance value and the second resistance value, control the heating control circuit to supply power to the circuit in which the first heating component and the second heating component are connected in series, so that the first heating component and the second heating component work in series; the series heating condition is that the difference between the ratio between the first target power of the first heating component and the second target power of the second heating component and the ratio between the first resistance value and the second resistance value is within a preset range;

[0098] If the series heating condition is not satisfied between the first resistance value of the first heating component and the second resistance value of the heating component, control the heating control circuit to supply power to the circuit in which the first heating component and the second heating component are connected in parallel, so that the first heating component generates heat and the second heating component works in parallel.

[0099] It can be understood that when the ratio P1 / P2 between the first target power P1 of the first heating component and the second target power P2 of the second heating component is equal to the ratio R1 / R2 between the first resistance value R1 and the second resistance value R2, or the difference between the two is within the preset range ▽V, it is considered that the TCR (Temperature Coefficient of Resistance) of the two heating components at this time is very small, and the temperature drift effect caused by TCR does not need to be considered. In this way, by adjusting the duty cycle of the PWM1 control signal, the first target power P1 and the second target power P2 can be ensured to be achieved. At this time, the resistance value in the circuit is the largest and the current is the smallest, which can improve the utilization rate of the battery cell power.

[0100] When it is detected that R1 / R2 < P1 / P2 - ▽V, or R1 / R2 > P1 / P2 + ▽V, it means that at this time, one of the heating components or both heating components have losses such as aging that cause changes in the resistance value of the heating components. At this time, the parallel heating method needs to be adopted, and the duty cycles of the PWM1 control signal and the PWM2 control signal are adjusted respectively to control the first heating component to reach the first target power P1 and the second heating component to reach the second target power P2.

[0101] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
