Description

Technical Field

[0001] This application relates to the field of electronic atomization equipment technology, specifically to an atomization device, its control method, and a computer storage medium. Background Technology

[0002] An electronic atomizing device is a device that uses a stored atomizable atomizing matrix to form an aerosol through heating or other methods. Electronic atomizing devices typically include an atomizer and a power supply structure. The power supply structure is electrically connected to the atomizer to provide power. The atomizer heats the atomizing matrix to atomize it, generating an aerosol for the user to inhale.

[0003] With the continuous development of the atomizing device market, dual-output atomizing devices are gradually gaining attention and popularity among consumers. Specifically, dual-output atomizing devices have two independent output channels, which can be connected to different atomizers to achieve the selection of different flavors or modes.

[0004] In a common dual-output atomizer, each channel uses a MOS switch to control its corresponding heating element for atomization. Compared to traditional single-output atomizers, driving the MOS switches for two channels requires a higher battery voltage, meaning a larger capacity battery, to ensure stable output. Otherwise, changes in vapor size and flavor can occur, leading to a poorer user experience. This undoubtedly increases battery costs and hinders the miniaturization of atomizers.

[0031] Multi-output atomizing devices are gaining increasing attention and popularity among consumers. Taking dual-output atomizing devices as an example, these devices have two independent output channels that can be connected to different atomizers, offering consumers the option to achieve different flavors or modes.

[0032] In a common dual-output atomizer control system, each channel uses a MOS switch to control its corresponding heating element for atomization. Currently, most dual-output atomizers control the output by simultaneously driving the MOS switches of both channels to achieve the desired power output. The duty cycle of the drive control signals for these MOS switches is 25%. With the output power of the heating elements in both channels remaining constant, compared to traditional single-output atomizers, driving the MOS switches of both channels requires a higher battery voltage—that is, a larger capacity battery with a higher voltage / current output—to ensure stable output. Otherwise, changes in vapor size and flavor will occur, leading to a poorer user experience. This undoubtedly increases the battery cost of the atomizer and hinders its miniaturization.

[0033] To address the aforementioned issues, this application proposes a method that, without altering the existing structure of multi-output atomizing devices, reduces the output current / voltage and discharge rate of the atomizing device's battery by changing the vacuum ratio of the drive signal of the driving control heating component. This allows for control over battery cost and size while maintaining the same output power of the heating component.

[0034] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the structure of an atomizing device provided in one embodiment of this application. Figure 1 As shown, the atomizing device provided in this application embodiment includes at least a heating module 110 and a drive control module 120.

[0036] In this embodiment, the atomizing device includes at least two heating modules 110. The heating modules 110 heat the atomizing matrix in the atomizing device, which generates an aerosol upon heating, providing the user with a cigarette-like experience. A drive control module 120 generates at least two drive control signals, each corresponding to one heating module 110, and drives the heating module 110 to operate; that is, the heating module 110 starts heating or stops heating under the drive control signal. A unique feature of this embodiment is that during the operation of the heating modules 110, within one working cycle of the drive control signal, the drive control module 120 drives at least one heating module to operate according to a preset power value, while simultaneously at least one heating module 110 is in a non-operating state.

[0037] In other words, the atomizing device provided in this embodiment has multiple heating modules 110, each heating module 110 including a heating unit 1101. Multiple driving control signals generated by the driving control module 120 correspond one-to-one with the heating units 1101 of the multiple heating modules 110, driving and controlling the heating units 1101 to enter the working state, starting heating and thus atomizing the atomizing matrix. Simultaneously, the multiple driving control signals have the same period. Within one working cycle of the driving control signals, at least one of the multiple heating modules 110 is in the working state, and one is in the non-working state; that is, multiple heating modules 110 do not simultaneously operate. In other words, within one working cycle, at least one driving control signal's effective level time period does not overlap with the effective level time periods of other driving control signals. It should be noted that, generally, the driving control signals used to control the operation of the heating modules 110 are PWM signals.

[0038] In a specific example, suppose an atomizing device has two heating modules 110, i.e., a dual-output atomizing device. Assume the voltage supplied by the battery in the atomizing device is Vcc, and the voltage obtained by each heating module 110 is U. n The resistance corresponding to each heating module 110 is R. n The preset output power value is P n Then, according to the power calculation formula P n =U n 2 / R n It can be seen that for each heating module 110, the voltage and resistance it receives are constant. If both heating modules 110 are working simultaneously, Vcc = U1 + U2 = P1*R1 + P2*R2. This shows that the battery voltage required when both heating modules 110 are working simultaneously is higher than the battery voltage required when one heating module 110 is not working. If one of the two heating modules 110 is not working, then according to P... n =U n 2 / R n It can be seen that the required battery voltage has been reduced.

[0039] As one implementation method, to ensure that during the operation of the heating module 110, the drive control module 120 drives at least one heating module to operate according to a preset power value within one working cycle of the drive control signal, while simultaneously at least one heating module 110 is in a non-operating state, the period of the drive control signal can be divided equally according to the number of heating modules 110. The effective level of each drive control signal can be at most or at least one equal part. Specifically, if the effective level of the drive control signal is low, the duty cycle of each drive control signal is greater than or equal to one-N equal parts of one working cycle; if the effective level of the drive control signal is high, the duty cycle of each drive control signal is less than or equal to one-N equal parts of one working cycle; where N is the number of heating modules 110.

[0040] As one implementation method, when the drive control module 120 drives the heating module 110 to work according to the preset power value, only one heating module 110 is in working state within one working cycle, while the rest of the heating modules 110 are in non-working state, and the effective level of each drive control signal can be at most or at least equal.

[0041] The duty cycle D of the drive control signal corresponding to each heating module 110 can be obtained by formula: P n =U n 2* (1-D) / R n The result is obtained through calculation, i.e., D = P. n *R n / U n 2 Furthermore, if the effective level of the drive control signal is low, then the duty cycle of each drive control signal satisfies: 1 / N ≤ D < 1, and (1-D) ≤ P. n *R n / U n 2 If the effective level of the drive control signal is high, then the duty cycle of each drive control signal satisfies: 0 < D ≤ 1 / N, and D ≤ P. n *R n / U n 2 .

[0042] Figure 2 This is a schematic diagram of the structure of an atomizing device provided in another embodiment of this application. Figure 2 As shown, the atomizing device provided in this embodiment, based on any of the above embodiments, further includes a voltage monitoring module 130 and a duty cycle module 140.

[0043] In this embodiment, the voltage monitoring module 130 is connected to the battery of the atomizing device to monitor the battery level. The duty cycle module 140 is connected to the voltage monitoring module 130 to acquire the monitoring voltage output by the voltage monitoring module 130, and adjusts the duty cycle of the drive control signal corresponding to each heating module 110 based on the monitoring voltage and the preset power and resistance values ​​of each heating module 110. As can be seen from the duty cycle calculation formula, the duty cycle of each drive control signal is positively correlated with the voltage obtained by the corresponding heating module 110. That is, for a heating module 110, the voltage it receives from the atomizing device battery may be the same or different, and the duty cycle of the drive control signal used to drive it is positively correlated with the voltage it receives; the higher the voltage, the larger the duty cycle.

[0044] In one embodiment, an atomizing device has N heating modules 110, each of which has a preset power output value. The preset power value and resistance value of each heating module 110 are the same. In this case, the duty cycle of the corresponding N drive control signals can also be the same, and it satisfies that it is greater than or equal to one Nth of a working cycle, or less than or equal to one Nth of a working cycle.

[0045] Figure 3 This is a schematic diagram of the structure of a heating module provided in one embodiment of this application. Figure 3 As shown, the heating module 110 provided in this embodiment includes at least a heating unit 1101, a switching unit 1102, a first voltage divider unit 1103, and a second voltage divider unit 1104.

[0046] In this embodiment, the first end of the first voltage divider unit 1103 is connected to the input voltage terminal, which is the battery output terminal of the atomizing device, to obtain the battery's power supply voltage; the first end of the second voltage divider unit 1104 is connected to the second end of the first voltage divider unit 1103, and the second end of the second voltage divider unit 1104 is connected to an output terminal of the drive control module 120 to obtain a drive control signal that drives the heating module 110 to start or stop working; the control terminal of the switch unit 1102 is connected to the second end of the first voltage divider unit 1103, the first end of the switch unit 1102 is connected to the input voltage terminal, which is the battery output terminal, and the second end of the switch unit 1102 is connected to the first end of the heating unit 1101; the second end of the heating unit 1101 is connected to a preset voltage terminal, which can be a ground terminal.

[0047] Figure 4 This is a circuit diagram of the heating module of a dual-output atomizing device according to one embodiment of this application. Figure 4As shown, the atomizing device in this embodiment includes two parallel heating modules 110, namely a first heating module and a second heating module. In the first heating module, the first heating unit includes a first heating resistor R1, the first switching unit includes a switching transistor Q1, the first voltage divider unit includes a voltage divider resistor R2, and the second voltage divider unit includes a voltage divider resistor R3. In the second heating module, the second heating unit includes a second heating resistor R4, the second switching unit includes a switching transistor Q2, the third voltage divider unit includes a voltage divider resistor R5, and the fourth voltage divider unit includes a voltage divider resistor R6.

[0048] Specifically, the control terminal of the switching transistor Q1 is connected to the second terminal of the voltage divider resistor R2, the first terminal of the switching transistor Q1 is connected to the battery output terminal of the atomizing device to obtain the input voltage Vcc, the second terminal of the switching transistor Q1 is connected to the first terminal of the first heating resistor R1, the second terminal of the first heating resistor R1 is grounded, the first terminal of the voltage divider resistor R2 is connected to the first terminal of the switching transistor Q1, the first terminal of the voltage divider resistor R3 is connected to the second terminal of the voltage divider resistor R2, and the second terminal of the voltage divider resistor R3 is used to obtain the drive control signal PWM1 that controls the first heating module.

[0049] The control terminal of the switching transistor Q2 is connected to the second terminal of the voltage divider resistor R5. The first terminal of the switching transistor Q2 is connected to the battery output terminal of the atomizing device to obtain the input voltage Vcc. The second terminal of the switching transistor Q2 is connected to the first terminal of the second heating resistor R2. The second terminal of the second heating resistor R2 is grounded. The first terminal of the voltage divider resistor R5 is connected to the first terminal of the switching transistor Q2. The first terminal of the voltage divider resistor R6 is connected to the second terminal of the voltage divider resistor R5. The second terminal of the voltage divider resistor R6 is used to obtain the drive control signal PWM2 that controls the second heating module.

[0050] In summary, the atomizing device provided in any of the above embodiments includes at least two heating modules and a drive control module. The heating modules heat the atomizing medium in the atomizing device, and the drive control module generates at least two drive control signals to drive at least one heating module to operate. Within one working cycle of the drive control signals, the drive control module drives at least one heating module to operate and heat it according to a preset power value, while simultaneously driving at least one heating module to operate in a non-operating state. Compared to existing multi-output atomizing devices, this application achieves the same output power by adjusting the drive control signals of the heating modules, thereby reducing the output voltage / current and discharge rate of the atomizing device's battery. This ensures both the size and flavor of the aerosol output by the atomizing device and also controls battery cost and size.

[0051] Figure 5 This is a flowchart illustrating a control method for an atomizing device according to an embodiment of this application. Figure 5As shown, the control method for the atomizing device provided in this embodiment is applied to a multi-output atomizing device, that is, the atomizing device has multiple heating modules, and the multi-output atomizing device also has a control module. The control module is used to execute the control method for the multi-output atomizing device, specifically including the following steps:

[0052] Step S510: Obtain the number of heating modules in the atomizing device.

[0053] Step S520: Generate multiple drive control signals for driving multiple heating modules to work.

[0054] Step S530: Within one working cycle, drive at least one heating module to work and output heat according to a preset power value, and control at least one heating module to be in a non-working state.

[0055] The control method for the atomizing device provided in this embodiment is applied to a multi-output atomizing device. This multi-output atomizing device has multiple heating modules, each controlled by a drive control signal. Therefore, when the control module controls the atomizing device to provide aerosol to the consumer according to a preset power value, it first determines the number of heating modules, which in turn determines the number of drive control signals needed to drive these heating modules to start or stop heating. Simultaneously, the multiple drive control signals have the same period. Within one working cycle of the drive control signals, at least one drive control signal is active, meaning that within one working cycle, at least one heating module can be driven to operate and generate heat, ensuring that the atomizing device provides the consumer with the desired experience according to the preset power value. At the same time, at least one drive control signal is inactive, meaning that within one working cycle, at least one heating module can be deactivated. In other words, multiple heating modules do not operate simultaneously, in order to ensure the size and flavor of the aerosol output by the atomizing device while reducing the output voltage / current and discharge rate of the atomizing device battery, thus controlling battery cost and size.

[0056] As an implementation method, in order to achieve the purpose of step S530 in the above embodiment, driving at least one heating module to work and output heating according to a preset power value within one working cycle, and controlling at least one heating module to be in a non-working state, it is also necessary to further determine the duty cycle of each driving control signal when generating multiple driving control signals for driving multiple heating modules to work in step S520. The vacuum ratio of each driving control signal is related to the number of heating modules in the atomizing device and the battery power.

[0057] Figure 6A flowchart illustrating a control method for an atomizing device according to another embodiment of this application. Figure 6 As shown, the control method for the atomizing device provided in this embodiment specifically includes the following steps:

[0058] Step S610: Obtain the number of heating modules in the atomizing device.

[0059] Step S620: Determine the duty cycle of each drive control signal based on the number of heating modules and the effective level of the drive control signal.

[0060] Step S630: Generate multiple drive control signals for driving multiple heating modules based on the duty cycle of each drive control signal.

[0061] Step S640: Within one working cycle, drive at least one heating module to work and output heat according to a preset power value, and control at least one heating module to be in a non-working state.

[0062] To achieve the goal of driving at least one heating module to operate according to a preset power value and heating within one working cycle of the drive control signal during the operation of the heating module, while simultaneously ensuring that at least one heating module is in a non-operating state, it is necessary to determine the duty cycle of each drive control signal based on the number of heating modules and the effective level of the drive control signal, thereby generating multiple corresponding drive control signals.

[0063] In one implementation, the period of the drive control signal can be divided equally according to the number of heating modules, with the effective level of each drive control signal accounting for at most or at least one equal part. Specifically, if the effective level of the drive control signal is low, the duty cycle of each drive control signal is greater than or equal to one-N equal parts of one working cycle; if the effective level of the drive control signal is high, the duty cycle of each drive control signal is less than or equal to one-N equal parts of one working cycle; where N is the number of heating modules.

[0064] As one implementation, determining the duty cycle of each drive control signal in step S620 includes:

[0065] Step S6201: Obtain the power of the atomizing device.

[0066] Step S6202: Based on the power of the atomizing device and the preset power and resistance values ​​of each heating module, adjust and determine the duty cycle of the drive control signal corresponding to each heating module.

[0067] The duty cycle D of the drive control signal corresponding to each heating module can be obtained by the formula: P n =U n2* (1-D) / R n The result is obtained through calculation, i.e., D = P. n *R n / U n 2 Furthermore, if the effective level of the drive control signal is low, then the duty cycle of each drive control signal satisfies: 1 / N ≤ D < 1, and (1-D) ≤ P. n *R n / U n 2 If the effective level of the drive control signal is high, then the duty cycle of each drive control signal satisfies: 0 < D ≤ 1 / N, and D ≤ P. n *R n / U n 2 .

[0068] Therefore, the duty cycle of the drive control signal corresponding to each heating module is related to the voltage obtained by that heating module from the atomizing device's battery, as well as the preset power and resistance values ​​of each heating module. Thus, determining the duty cycle of the drive control signal corresponding to each heating module requires obtaining the battery charge of the atomizing device, as well as the preset power and resistance values ​​of each heating module. The corresponding duty cycle can then be calculated using a formula.

[0069] In one implementation, an atomizing device has N heating modules, each with its own preset power output value. The preset power and resistance values ​​of each heating module are identical. In this case, the duty cycles of the corresponding N drive control signals can also be the same, and:

[0070] When the effective level of the drive control signal is low, the duty cycle of each drive control signal satisfies: 1 / N ≤ D < 1, and (1-D) ≤ P. n *R n / U n 2 When the effective level of the drive control signal is high, the duty cycle of each drive control signal satisfies: 0 < D ≤ 1 / N, and D ≤ P. n *R n / U n 2 .

[0071] All of them achieved the goal of reducing the output voltage / current and discharge rate of the atomizing device battery by adjusting the drive control signal of the driving heating module under the same output power. This ensured the size and taste of the aerosol output by the atomizing device, and also achieved control over battery cost and size.
