Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and particularly to an output control component, method, and device for an atomization device. Background Art

[0002] In an atomization device, when the atomization core outputs atomization, it is necessary to obtain the output voltage of the atomization core for feedback regulation to stabilize the voltage output of the atomization device. This process is crucial for ensuring the stability and consistency of the atomization effect. However, in traditional atomization device control components, it is necessary to further control the output of the atomization core according to the feedback output voltage, which not only occupies computing resources but also increases the circuit size, thereby increasing costs and being unfavorable for the sustainable development of atomization devices.

[0003] PWM (Pulse Width Modulation) technology is a very important concept in embedded systems, especially when controlling some devices that require analog signals, such as LEDs, motors, or servos. PWM is a technology that simulates analog signals by modulating digital signals. Simply put, it is to simulate analog signals of different amplitudes by changing the width of digital signal pulses. In an atomization device, PWM technology can be used to precisely control the output voltage, thereby achieving precise control of the atomization core. By adjusting the duty cycle of the PWM signal, analog signals of different amplitudes can be simulated, and then the working state of the atomization core can be controlled.

[0004] However, traditional control methods require complex calculations and large circuit designs, which not only increase costs but also are unfavorable for the miniaturization and efficiency improvement of devices. Therefore, researching how to simplify the control process, reduce computing resource occupancy, and circuit size is of great significance for the sustainable development of atomization devices.

[0053] Reference Figure 1 , the output control component of the atomizing device of this application includes:

[0054] Power supply device 1, detection sensor 2, control unit 3, display unit 4, DC output unit 5, atomizing core 6;

[0055] The power supply device 1 is connected to the control unit 3, the control unit 3 is connected to the detection sensor 2 for detecting whether the atomizing device is in a triggered state, the display unit 4 is connected to the control unit 3 for displaying the working state of the control unit 3, and the DC output unit 5 is connected to the control unit 3 for receiving a PWM signal with a specified duty cycle output by the control unit 3 according to different output modes in the triggered state. The DC output unit 5 includes a DC boost circuit 51 and a DC buck circuit 52. The atomizing core 6 is respectively connected to the DC boost circuit 51 and the DC buck circuit 52 for atomizing by adjusting the output DC voltage according to the DC boost circuit 51 or the DC buck circuit 52 with the PWM signal.

[0056] In this embodiment, the atomizing device may be an electronic cigarette. The power supply device is used to supply power to the control unit in the electronic cigarette. The detection sensor is used to detect a specific action on the atomizing device (electronic cigarette), such as a user sucking on the electronic cigarette. When the detection sensor detects the user's sucking action, it feeds back this information to the control unit. The control unit generates corresponding working state information, and the display unit displays this working state information. The DC output unit is used to output different DC voltages to the atomizing core according to the working state information and the set output mode, and then the atomizing core heats according to the output DC voltage to produce an atomizing effect.

[0057] This application realizes an atomizing device output control component including a power supply device 1, a detection sensor 2, a control unit 3, a display unit 4, a DC output unit 5, and an atomizing core 6. The power supply device 1 is connected to the control unit 3, the control unit 3 is connected to the detection sensor 2 for detecting whether the atomizing device is in a triggered state, the display unit 4 is connected to the control unit 3 for displaying the working state of the control unit 3, the DC output unit 5 is connected to the control unit 3 for receiving a PWM signal with a specified duty cycle output by the control unit 3 according to different output modes in the triggered state. The DC output unit 5 includes a DC boost circuit 51 and a DC buck circuit 52. The atomizing core 6 is respectively connected to the DC boost circuit 51 and the DC buck circuit 52 for atomizing by the DC voltage output with the PWM signal according to the DC boost circuit 51 or the DC buck circuit 52. Thus, it effectively realizes setting the DC voltage output to the atomizing core according to different output modes, so as to effectively adjust the output of the atomizing core without a feedback voltage and improve the stability of voltage output.

[0058] Continue to refer to Figure 2, the DC boost circuit 51 includes a first power supply V1, a first switching transistor Q1, a first switching control sub-unit P1, a first diode D1, a first inductor L1, a first capacitor C1, and a first ground terminal GND1;

[0059] One end of the first inductor L1 is connected to the first power supply V1, the other end of the first inductor L1 is serially connected to the first diode D1, the drain of the first switching transistor Q1 is connected to the common connection point of the first inductor L1 and the first diode D1, the source of the first switching transistor Q1 is connected to the first ground terminal GND1, the gate of the first switching transistor Q1 is connected to the first switching control sub-unit P1, one end of the first capacitor C1 is connected to the first diode D1, and the other end of the first capacitor C1 is connected to the first ground terminal GND1.

[0060] In this embodiment, the other end of the first power supply V1 is connected to the first ground terminal GND1. When the first switching transistor Q1 is turned on, current flows from the first power supply V1 through the first switching transistor Q1 and the first inductor L1 to the first ground terminal GND1. At this time, the first inductor L1 stores energy. Since the resistive heating wire RL of the atomizing core is connected in parallel between the first capacitor C1 and the first ground terminal GND1, when the first switching transistor Q1 is turned off, the energy stored in the first inductor L1 is released to the first capacitor C1 and the resistive heating wire RL through the first diode D1. Due to the functions of the first inductor L1 and the first capacitor C1, the output voltage across the resistive heating wire RL is higher than the input voltage of the first power supply V1 at this time, thereby forming a boost effect and outputting a corresponding DC voltage.

[0061] In this embodiment, by providing the DC boost circuit 51 including the first power supply V1, the first switching transistor Q1, the first switching control sub-unit P1, the first diode D1, the first inductor L1, the first capacitor C1, and the first ground terminal GND1, the DC voltage output to the atomizing core 6 can be effectively boosted according to the regulation of the control unit 3, without voltage feedback, reducing resource occupation and lowering the circuit cost.

[0062] In an optional embodiment of this embodiment, the DC boost circuit 51 is connected to the resistive heating wire RL of the atomizing core 6, and the resistive heating wire RL is connected in parallel between the first capacitor C1 and the first ground terminal GND1.

[0063] In this embodiment, the energy stored in the first inductor L1 is finally released to the first capacitor C1 and the resistive heating wire RL. By storing this energy, the first capacitor C1 enables the current in the first capacitor C1 not to immediately drop to zero but to gradually decrease when the first switching transistor Q1 is turned off, thereby effectively maintaining the continuity of the current in the circuit. When the resistive heating wire RL receives the energy stored in the first capacitor C1, it generates heat according to this energy to heat the solid or liquid atomized substance installed in the atomization core 6 to form atomized gas.

[0064] In this embodiment, by connecting the resistive heating wire RL in parallel between the first capacitor C1 and the first ground terminal GND1, the energy released by the first inductor L1 can effectively reach the first capacitor C1 while reaching the resistive heating wire RL, effectively ensuring the stability of the circuit and enabling the resistive heating wire RL to generate heat normally.

[0065] Continue to refer to Figure 3 , the DC buck circuit 52 includes a second power supply V2, a second switching transistor Q2, a second switching control sub-unit P2, a second diode D2, a second inductor L2, a second capacitor C2, and a second ground terminal GND2;

[0066] The drain of the second switching transistor Q2 is connected to the second power supply V2, the source of the second switching transistor Q2 is connected to one end of the second inductor L2, the gate of the second switching transistor Q2 is connected to the second switching control sub-unit P2, one end of the second diode D2 is connected to the other end of the second inductor L2, the other end of the second diode D2 is connected to the second ground terminal GND2, and the second capacitor C2 is connected in parallel with the second diode D2.

[0067] In this embodiment, the other end of the second power supply V2 is connected to the second ground terminal GND2. When the second switching transistor Q2 is turned on, current flows from the second power supply V2 through the second switching transistor Q2 and the second inductor L2 to the resistive heating wire RL for power supply, and at the same time, the second capacitor C2 is charged. At this time, the second inductor L2 stores energy. When the second switching transistor Q2 is turned off, the energy stored in the second inductor L2 cannot return to the second power supply V2 through the second switching transistor Q2 and can only continue to supply power to the second capacitor C2 and the resistive heating wire RL through the second diode D2 to maintain the load current. Due to the control of the on and off time ratio of the second switching transistor Q2, the output voltage across the resistive heating wire RL is lower than the input voltage of the second power supply V2 at this time, thereby forming a buck effect and outputting a corresponding DC voltage.

[0068] In this embodiment, a DC buck circuit 52 including a second power supply V2, a second switching transistor Q2, a second switching control subunit P2, a second diode D2, a second inductor L2, a second capacitor C2, and a second ground terminal GND2 is provided, so as to effectively step down the DC voltage output to the atomizing core 6 according to the regulation of the control unit 3 without voltage feedback, reducing resource occupation and circuit cost.

[0069] In an alternative embodiment of this embodiment, the DC buck circuit 52 is connected to the resistive heating wire RL of the atomizing core 6, and the resistive heating wire RL is connected in parallel between the second capacitor C2 and the second ground terminal GND2.

[0070] In this embodiment, the energy stored in the second inductor L2 is finally released into the second capacitor C2 and the resistive heating wire RL. By storing this energy, the second capacitor C2 enables the current in the second capacitor C2 not to immediately drop to zero but gradually decrease when the second switching transistor Q2 is turned off, effectively maintaining the current continuity in the circuit. When the resistive heating wire RL receives the energy stored in the second capacitor C2, it generates heat according to this energy to heat the solid or liquid atomizing substance installed in the atomizing core 6 to form atomized gas.

[0071] In this embodiment, by connecting the resistive heating wire RL in parallel between the second capacitor C2 and the second ground terminal GND2, the energy released by the second inductor L2 can effectively reach the second capacitor C2 while reaching the resistive heating wire RL, effectively ensuring the stability of the circuit and enabling the resistive heating wire RL to generate heat normally.

[0072] This application also provides a method for controlling the output of an atomizing device. Further reference is made to Figure 4 , which shows a flowchart of an embodiment of the method for controlling the output of an atomizing device according to this application. The method for controlling the output of an atomizing device includes the following steps:

[0073] Step S10, obtaining real-time detection information of a preset sensor;

[0074] In this embodiment, the preset sensor can be a pressure sensor or a pressure sensor and a temperature sensor. The preset sensor is used to determine whether the atomizing device needs to be activated. For example, to determine whether an electronic cigarette is activated, it can be judged by detecting whether the pressure sensor is subjected to the pressure of the user's mouth and whether the temperature sensor senses the user's temperature to determine whether the electronic cigarette is being puffed by the user. When the preset sensor detects that the user makes a puffing action, the corresponding real-time detection information is obtained by acquiring the sensing information of the preset sensor.

[0075] Step S20, determining whether the output control component of the atomizing device is in a triggered state according to the real-time detection information;

[0076] In this embodiment, the real-time detection information refers to the sensor parameters detected by a preset sensor, and the trigger state means that the sensor parameters detected by the preset sensor reach a preset threshold. For example, the pressure value detected by a pressure sensor reaches the preset pressure threshold, or the temperature value detected by a temperature sensor reaches the preset temperature threshold. By comparing and judging the real-time detection information with the preset threshold, it is determined whether the atomization device output control component is in the trigger state.

[0077] Step S30, if the atomization device output control component is in the trigger state, obtain the current output mode of the atomization device output control component, and identify whether the current output mode is constant voltage output or constant power output;

[0078] In this embodiment, the current output mode is the output mode preset in the control unit. In this embodiment, the output modes include constant voltage output mode and constant power output mode. In the constant voltage output mode, the control unit keeps the voltage across the atomization core constant, regardless of the change in the resistance value of the atomization core. The constant voltage output mode is suitable for maintaining a certain taste and steam volume. In the constant power output mode, the control unit keeps the power passing through the atomization core constant, which means that the product of voltage and current remains unchanged. The constant power output mode is suitable for obtaining similar power outputs on atomization cores with different resistance values. The constant voltage output mode (CV) and the constant power output mode (CP) can be identified by reading the mode information set in the control unit. In this embodiment, there will be a register or storage area inside the control unit for storing the currently selected working mode (CV or CP). The control unit will regularly read the stored mode information during startup or during operation to effectively identify the current output mode.

[0079] Step S40, if the current output mode is the constant voltage output, calculate the first output voltage according to the constant voltage algorithm and the preset data, and output the first output voltage to the atomization core for atomization control;

[0080] In this embodiment, under constant voltage output, the control unit adjusts the PWM signal of the DC output unit to ensure that the voltage across the atomization core is maintained at the preset value, even if the resistance value of the atomization core changes. The constant voltage algorithm refers to calculating the duty cycle of the first PWM signal to be output effectively to output the first output voltage when the output voltage across the atomization core remains constant.

[0081] Step S50, if the current output mode is the constant power output, calculate the second output voltage according to the constant power algorithm and the preset data, and output the second output voltage to the atomization core for atomization control;

[0082] In this embodiment, under constant power output, the control unit adjusts the PWM signal of the DC output unit to ensure that the power passing through the atomization core is maintained at a preset value even when the resistance of the atomization core changes. The constant power algorithm refers to calculating the corresponding second output voltage and the duty cycle of the second PWM signal when the power of the atomization core remains constant, so as to effectively output the second output voltage.

[0083] Step S60, if the atomization device output control component is not in the trigger state, then obtain the real-time detection information again after the next preset time interval for judgment until the atomization device output control component is in the trigger state or the atomization device output control component stops the detection action.

[0084] In this embodiment, the preset time interval refers to the time interval for performing the action of obtaining the real-time detection information again. When the atomization device output control component stops the detection action, such as when the power of the first power source is exhausted, or when the atomization device output control component is in the trigger state, the action of obtaining the real-time detection information at the preset time interval is stopped. In this embodiment, the preset time interval is 1 s and can be adjusted accordingly according to the actual situation.

[0085] In this embodiment, the real-time detection information of a preset sensor is obtained; it is judged whether the atomization device output control component is in the trigger state according to the real-time detection information; if the atomization device output control component is in the trigger state, the current output mode of the atomization device output control component is obtained, and it is identified whether the current output mode is constant voltage output or constant power output; if the current output mode is the constant voltage output, the first output voltage is calculated according to the constant voltage algorithm and preset data, and the first output voltage is output to the atomization core for atomization control; if the current output mode is the constant power output, the second output voltage is calculated according to the constant power algorithm and the preset data, and the second output voltage is output to the atomization core for atomization control; if the atomization device output control component is not in the trigger state, then obtain the real-time detection information again after the next preset time interval for judgment until the atomization device output control component is in the trigger state or the atomization device output control component stops the detection action. Thus, the output voltage is effectively calculated and output for atomization control according to the current different output modes of the atomization device, so as to effectively adjust the output of the atomization core without obtaining voltage feedback and improve the stability of voltage output.

[0086] In an optional embodiment of this embodiment, before identifying whether the current output mode is constant voltage output or constant power output, the following steps are further included:

[0087] Set the initial atomizing core resistance value, initial output voltage, initial power supply voltage, and initial signal duty cycle corresponding to the current voltage test point;

[0088] In this embodiment, the initial atomizing core resistance value refers to the set atomizing core resistance value, initially set to 0.5 Ω. The initial output voltage refers to the set output voltage applied to the resistance heating wire RL, initially set to 3.3 V. The initial power supply voltage refers to the voltage value set by the power supply, initially set to 4.2 V. The initial signal duty cycle refers to the set PWM signal duty cycle, initially set to 50%. The above initial atomizing core resistance value, initial output voltage, initial power supply voltage, and initial signal duty cycle can be adjusted correspondingly according to actual situations. In this embodiment, the above set initial atomizing core resistance value, initial output voltage, initial power supply voltage, and initial signal duty cycle are used for testing to obtain corresponding preset data, which are recorded in groups. Each group of initial atomizing core resistance value, initial output voltage, initial power supply voltage, and initial signal duty cycle corresponds to a voltage test point. The specific value of the output voltage corresponding to this voltage test point, for example, the output voltage corresponding to voltage test point 1 is 3 V, the output voltage corresponding to voltage test point 2 is 3.1 V, the output voltage corresponding to voltage test point 3 is 3.2 V, and it is set with a 0.1 V step, and so on. Among them, the output voltage corresponding to the above voltage test point refers to the voltage across the resistance heating wire RL.

[0089] Perform atomizing output according to the initial atomizing core resistance value, the initial output voltage, the initial power supply voltage, and the initial signal duty cycle, and detect the real-time output voltage;

[0090] In this embodiment, according to the above initial parameters, the first switch control sub-unit and the second control sub-unit are used to adjust the conduction and cut-off of the switch tube to generate the required output voltage. Among them, the first switch control sub-unit and the second switch control sub-unit are regulated by the control unit. According to the initial signal duty cycle, the conduction time of the switch tube is controlled, thereby adjusting the real-time output voltage. The real-time output voltage can be measured in real time by an external measuring device. Among them, the external measuring device can use an oscilloscope or a digital multimeter to measure the voltage across the atomizing core in real time to obtain the real-time output voltage.

[0091] Judge whether the real-time output voltage meets the set threshold;

[0092] In this embodiment, the set threshold range corresponding to the real-time output voltage is ±5% of the set output voltage, and it can be adjusted correspondingly according to the situation. By numerically comparing the real-time output voltage with the set threshold, it can be effectively judged whether the real-time output voltage meets the set threshold.

[0093] If the real-time output voltage meets the set threshold, adjust the initial output voltage and the initial power supply voltage to continue with the test steps for the next voltage test point until all voltage test points are traversed. After traversing all the voltage test points, record the initial atomizing core resistance value, the real-time output voltage, the initial power supply voltage, and the initial signal duty cycle corresponding to all the voltage test points into the preset data for storage;

[0094] In this embodiment, multiple voltage test points are initially set. For example, if the range of the voltage test points is 4V - 6V, then the voltage test points are 4V, 4.1V, 4.2V... 5.8V, 5.9V, 6V, and the range of the voltage test points can be adjusted according to the actual situation. The preset data records the initial atomizing core resistance value, the real-time output voltage, the initial power supply voltage, and the initial signal duty cycle corresponding to a single voltage test point in a group. This preset data is used to display the corresponding relationship between these parameters. When the parameter data of all the voltage test points are recorded, the preset data containing the corresponding relationships of multiple groups of different voltage value parameters is obtained.

[0095] If the real-time output voltage does not meet the set threshold, adjust the initial signal duty cycle and repeat the steps of atomizing output and detecting the real-time output voltage until the real-time output voltage meets the set threshold, and record the adjusted signal duty cycle into the preset data for storage.

[0096] In this embodiment, the proportion of adjusting the initial signal duty cycle can be adjusted by 1% each time to obtain a more accurate real-time output voltage, and the proportion of adjusting the initial signal duty cycle can be adjusted correspondingly according to the actual situation.

[0097] In this embodiment, the initial atomizing core resistance value, the initial output voltage, the initial power supply voltage, and the initial signal duty cycle corresponding to the current voltage test point are set; atomizing output is performed according to the initial atomizing core resistance value, the initial output voltage, the initial power supply voltage, and the initial signal duty cycle, and the real-time output voltage is detected; it is determined whether the real-time output voltage meets a set threshold; if the real-time output voltage meets the set threshold, the initial output voltage and the initial power supply voltage are adjusted to continue the test step of the next voltage test point until all voltage test points are traversed, and after all the voltage test points are traversed, the initial atomizing core resistance value, the real-time output voltage, the initial power supply voltage, and the initial signal duty cycle corresponding to all the voltage test points are recorded in the preset data for storage; if the real-time output voltage does not meet the set threshold, the initial signal duty cycle is adjusted, and the steps of atomizing output and detecting the real-time output voltage are repeated until the real-time output voltage meets the set threshold, and the adjusted signal duty cycle is recorded in the preset data for storage. Thus, the preset data recording the corresponding relationship between the initial atomizing core resistance value, the real-time output voltage, the initial power supply voltage, and the initial signal duty cycle can be effectively obtained, so as to facilitate the subsequent calculation of the first output voltage and the second output voltage.

[0098] Continue to refer to Figure 5 , in some alternative implementation manners of this embodiment, step S40 includes the following steps:

[0099] Step S401, obtain the set first output voltage and the detected first power supply voltage;

[0100] In this embodiment, the first output voltage refers to the constant voltage output voltage set by the atomizing device in the current constant voltage output mode, and the first power supply voltage refers to the real voltage obtained by measuring the first power supply in the current constant voltage output mode.

[0101] Step S402, determine the first duty cycle in the preset data according to the first power supply voltage and the first output voltage;

[0102] In this embodiment, matching search is performed in the preset data through the first power supply voltage and the first output voltage to find the corresponding first duty cycle. For example, if a set of initial atomizing core resistance value, real-time output voltage, initial power supply voltage, and initial signal duty cycle (or adjusted signal duty cycle) that match are found in the preset data through the first power supply voltage and the first output voltage, then the initial signal duty cycle (or adjusted signal duty cycle) in this set of parameter data is used as the first duty cycle.

[0103] Step S403: Output a first PWM signal with a corresponding duty cycle according to the first duty cycle, and output the first output voltage according to the first PWM signal.

[0104] In this embodiment, the switch control sub-unit in the DC boost circuit or the DC buck circuit generates a corresponding first PWM signal according to the first duty cycle. This first PWM signal switches between a high level and a low level, and the proportion of the time of the high level in the entire cycle is the duty cycle. For example, if the first duty cycle is 78.57%, then in each cycle, the first PWM signal is at a high level for approximately 78.57% of the time and at a low level for 21.43% of the time. The first PWM signal controls the charging and discharging processes of the inductor, capacitor, and heating wire resistor through a switching transistor, thereby generating an average voltage across the load, and this average voltage is the first output voltage. By adjusting the duty cycle of the first PWM signal, the average voltage across the load can be precisely controlled to achieve precise control of the atomizing core. In this embodiment, in the constant voltage output mode, whether to boost or buck depends on the relationship between the required output voltage and the power supply voltage. The goal of the constant voltage mode is to keep the output voltage constant, regardless of changes in the power supply voltage or load. When the required output voltage is lower than the power supply voltage, a DC buck circuit is required to step down the voltage. In this case, the second switch control sub-unit adjusts the conduction time of the second switching transistor to reduce the duration of the high level state (i.e., reduce the duty cycle), thereby reducing the output voltage to the required constant value. When the required output voltage is higher than the power supply voltage, a DC boost circuit is required to step up the voltage. In this case, the first switch control sub-unit adjusts the conduction and turn-off of the first switching transistor to increase the duration of the high level state (i.e., increase the duty cycle), and at the same time utilizes the inductor to store and release energy, thereby increasing the output voltage to the required constant value.

[0105] In this embodiment, by obtaining the set first output voltage and the detected first power supply voltage; determining the first duty cycle in the preset data according to the first power supply voltage and the first output voltage; outputting a first PWM signal with a corresponding duty cycle according to the first duty cycle, and outputting the first output voltage according to the first PWM signal. Thus, it effectively realizes accurate and effective voltage output control of the atomizing core according to the preset data in the constant voltage output mode, so as to effectively adjust the output of the atomizing core without obtaining a feedback voltage.

[0106] Continue to refer to Figure 6 , in some alternative implementation manners of this embodiment, step S50 includes the following steps:

[0107] Step S501: Obtain the detected resistance value of the atomizing core and the detected second power supply voltage;

[0108] In this embodiment, the detected resistance value of the atomizing core refers to the resistance value obtained by measuring the atomizing core in the constant power output mode, and the second power supply voltage refers to the voltage value obtained by measuring the second power supply in the constant power output mode.

[0109] Step S502: Calculate the second output voltage according to the preset constant output power and the resistance value of the atomizing core.

[0110] In this embodiment, according to the preset constant output power (e.g., 10W) and the detected resistance value of the atomizing core, the formula P = V 2 / R is used to calculate the required output voltage. Where P is the constant output power, V is the second output voltage, and R is the resistance value of the atomizing core.

[0111] Step S503: Determine the second duty cycle according to the second power supply voltage and the second output voltage in the preset data.

[0112] In this embodiment, the second power supply voltage and the second output voltage are used to perform a matching search in the preset data to find the corresponding second duty cycle. For example, if a set of matching initial atomizing core resistance values, real-time output voltage, initial power supply voltage, and initial signal duty cycle (or adjusted signal duty cycle) are found in the preset data through the second power supply voltage and the second output voltage, then the initial signal duty cycle (or adjusted signal duty cycle) in this set of parameter data is used as the second duty cycle.

[0113] Step S504: Output a second PWM signal with the corresponding duty cycle according to the second duty cycle, and output the second output voltage according to the second PWM signal.

[0114] In this embodiment, the switch control sub-unit in the DC boost circuit or the DC buck circuit generates a corresponding second PWM signal according to the second duty cycle. The second PWM signal switches between a high level and a low level, and the proportion of the time of the high level in the whole cycle is the duty cycle. For example, if the second duty cycle is 78.57%, then in each cycle, the second PWM signal is at a high level for approximately 78.57% of the time and at a low level for 21.43% of the time. The second PWM signal controls the charging and discharging processes of the inductor, capacitor, and heating wire resistor through a switching transistor, thereby generating an average voltage across the load, and this average voltage is the second output voltage. By adjusting the duty cycle of the second PWM signal, the average voltage across the load can be accurately controlled, achieving precise control of the atomizing core. In this embodiment, in the constant power output mode, the control system needs to monitor the resistance value of the atomizing core and the actual power output, and dynamically adjust the duty cycle according to this information to adapt to the change in resistance value and maintain a constant power output. When the resistance value of the atomizing core increases, for a given power, if the resistance value increases, then the current will decrease (I = V / P, where P is the constant power and V is the output voltage). To maintain a constant power, if the power supply voltage remains unchanged, then a DC buck circuit is required to step down the voltage, which can be achieved by reducing the duty cycle of the PWM signal output by the control unit. When the resistance value of the atomizing core decreases, for a given power, if the resistance value decreases, then the current will increase. To maintain a constant power, if the power supply voltage remains unchanged, then a DC boost circuit is required to step up the voltage, and this boost can be achieved by increasing the duty cycle of the PWM signal output by the control unit.

[0115] This embodiment obtains the detected resistance value of the atomizing core and the detected second power supply voltage; calculates the second output voltage according to the preset constant output power and the resistance value of the atomizing core; determines the second duty cycle according to the second power supply voltage and the second output voltage in the preset data; outputs a second PWM signal with a corresponding duty cycle according to the second duty cycle, and outputs the second output voltage according to the second PWM signal. Thus, it effectively realizes accurate and effective voltage output control of the atomizing core according to preset data in the constant power output mode, so as to effectively adjust the output of the atomizing core without obtaining the feedback voltage.
