[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] The atomizing device control method provided in the embodiment of the present application is used to control the atomizing device. The atomizing device includes at least two atomizers, that is, it can include two atomizers, or include a greater number of atomizers. It is understood that each atomizer can be arranged in a different atomizing chamber to reduce interference with each other's work. Alternatively, multiple atomizers can share one atomizing chamber to reduce the structural complexity of the atomizing device.

[0065] The atomizer includes a heating element and an atomizing matrix. The heating element is used to heat the atomizing matrix to atomize the atomizing matrix and generate an aerosol. The heating element can be a heating wire or a heating tube, etc., and the specific form is not limited.

[0066] Generally, the types of atomizing substrates in each atomizer are different. When each atomizer is heated, different types of aerosols can be generated, so that the atomizing device can provide rich types of aerosols and has a wider range of applications.

[0067] The atomization device control method can be executed by a processor, which can be a controller disposed in the atomization device, or other terminals or servers that have established a communication connection with the atomization device and can exchange data with the atomization device. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices, and the portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be implemented as an independent server or a server cluster consisting of multiple servers.

[0068] In one embodiment, Figure 1 As shown, a method for controlling an atomizing device is provided, and the method is described by taking the method applied to a controller in the atomizing device as an example, and the method includes the following steps:

[0069] Step 104: if a start signal is received, the sampling resistance and sampling voltage of each atomizer are obtained.

[0070] The start signal is used to indicate that the atomizing device needs to be started. The type of the start signal is not unique. For example, the start signal can be a suction signal detected by an airflow sensor in the atomizing device, and the airflow sensor is connected to the controller. Alternatively, the start signal can also be obtained according to a start instruction sent by the user through an interactive device, and the interactive device is connected to the controller. The interactive device can be a button, a display screen, or a voice device, etc.

[0071] After receiving the start signal, the controller obtains the sampling resistance and sampling voltage of each atomizer. Specifically, the sampling resistance and sampling voltage of each atomizer can be detected by a sampling circuit. The number of sampling circuits is equal to the number of atomizers. One sampling circuit is connected to one atomizer, and each sampling circuit is connected to the controller. The controller obtains the sampling resistance and sampling voltage of each atomizer through each sampling circuit. The structure of the sampling circuit is not limited, as long as resistance sampling and voltage sampling can be realized.

[0072] Step 106: Determine a control signal corresponding to each atomizer based on the sampling resistance and the sampling voltage.

[0073] The sampling resistance and the sampling voltage are used to characterize the working state of the atomizer. After obtaining the sampling resistance and the sampling voltage, the control signal corresponding to each atomizer can be determined based on the sampling resistance and the sampling voltage. It can be understood that when determining the control signal corresponding to each atomizer based on the sampling resistance and the sampling voltage, the variable to be adjusted can also be obtained by combining the invariant, the sampling resistance and the sampling voltage in the setting parameters, and the variable to be adjusted is the control signal.

[0074] Step 108: Control each atomizer separately based on the control signal.

[0075] The control signal and the atomizer are in a one-to-one correspondence. After the control signal corresponding to each atomizer is obtained, each control signal is sent to the corresponding atomizer to control each atomizer.

[0076] In the above-mentioned atomizer control method, if a start signal is received, the sampling resistance and sampling voltage of each atomizer are obtained, and the control signal corresponding to each atomizer is determined based on the sampling resistance and sampling voltage. The type of the control signal corresponds to the type of the adjustment parameter, and each atomizer is controlled separately based on the control signal. Thus, based on the sampling resistance and sampling voltage of each atomizer, a corresponding control signal is obtained, and the atomizer is controlled separately according to the control signal, so that the control of the atomizer can be adjusted according to the actual working state of the atomizer, which is conducive to improving the accuracy of controlling the atomizer, optimizing the atomization parameters of the atomizer, making the atomizer meet the preset working state, and also diversifying the control method to meet the diversified aerosol use needs.

[0077] In one embodiment, Figure 2 As shown, the atomization device control method further includes step 202 and step 204 .

[0078] It can be understood that the role of step 202 and step 204 is to determine the type of adjustment parameter. The type of the control signal corresponds to the type of adjustment parameter. The control signal is a value corresponding to the type of the adjustment parameter. Exemplarily, if the adjustment parameter type is heating time, the specific value of the heating time can be obtained according to the sampling resistance and the sampling voltage.

[0079] Among them, the adjustment parameter type is the type of parameter that needs to be adjusted, and the adjustment parameter type is the parameter that affects the aerosol generated by the nebulizer. Exemplarily, the adjustment parameter type can be the heating time, and the heating time includes the heating start time, the heating end time and the heating duration, etc. The heating start time and the heating end time affect the order in which each nebulizer generates aerosols, thereby affecting the aerosol provision order of the atomizing device. The heating duration affects the amount of aerosol generated by each nebulizer, thereby affecting the proportional relationship of the aerosol of the atomizing device. Generally, the longer the heating duration, the more aerosol is generated by the nebulizer, and the shorter the heating duration, the less aerosol is generated by the nebulizer. It can be understood that in other embodiments, the adjustment parameter type can also be other, as long as the technicians in this field think it can be achieved.

[0080] Step 202, determining the working mode of the atomization device.

[0081] There is not only one way to determine the working mode of the atomizer. For example, the atomizer has multiple preset working modes, and the atomizer provides the multiple working modes to the user for the user to choose. The user can select the working mode through the interactive device, and the atomizer determines the working mode selected by the user as the working mode of the atomizer. Alternatively, the manufacturer obtains the user's preferred working mode based on data analysis and other methods, and when manufacturing the atomizer, the user's preferred working mode is used as the working mode of the atomizer. Both of the above methods can make the working mode of the atomizer meet the user's needs.

[0082] Step 204: Determine the adjustment parameter type according to the determined working mode.

[0083] Different working modes have corresponding adjustment parameter types. The correspondence between the working mode and the adjustment parameter type can be set in advance and stored in the controller. After the controller determines the working mode of the atomizer, the adjustment parameter type can be determined by calling the correspondence between the working mode and the adjustment parameter type.

[0084] In this embodiment, after determining the working mode of the atomizer device, the adjustment parameter type is determined according to the determined working mode, so that the working mode of the atomizer device can meet user needs, and the atomizer is controlled based on the determined adjustment parameter type, so that the operation of the atomizer device can meet user needs.

[0085] Exemplarily, the working modes include a cooperative cycle mode and an independent cycle mode, such as Figure 3 As shown, step 204 includes step 304 or step 306 .

[0086] Step 304: If the working mode is the cooperative cycle mode, determine that the adjustment parameter type is heating time.

[0087] The collaborative cycle mode means that each atomizer works in coordination, and all atomizers complete a cycle together as a collaborative cycle. Specifically, the starting point of the collaborative cycle is the heating start time of the first heated atomizer among all atomizers, and the end point of the collaborative cycle is the heating end time of the last heated atomizer among all atomizers.

[0088] If the working mode is the coordinated cycle mode, the adjustment parameter type is determined to be the heating time. By adjusting the heating time of each atomizer, the aerosol generation order and mixing ratio of the atomizer device can be adjusted to meet different aerosol usage requirements.

[0089] Step 306: If the working mode is the independent cycle mode, determine that the adjustment parameter type is at least one of heating power or heating frequency.

[0090] The independent cycle mode means that each atomizer works independently, that is, each atomizer works according to its own heating cycle.

[0091] If the working mode is the independent cycle mode, the adjustment parameter type is determined to be at least one of the heating power or the heating frequency. By adjusting the heating power of each atomizer, or adjusting the heating frequency of each atomizer, or adjusting both the heating power and the heating frequency of each atomizer, the mixing ratio of the aerosol of the atomizing device can be changed, thereby meeting different aerosol usage requirements.

[0092] In this embodiment, the working mode includes a cooperative cycle mode and an independent cycle mode. If the working mode is the cooperative cycle mode, the adjustment parameter type is determined to be the heating time. If the working mode is the independent cycle mode, the adjustment parameter type is determined to be at least one of the heating power or the heating frequency. By adjusting the heating time of each atomizer, the generation order and the mixing ratio of the aerosol of the atomizer device can be adjusted. By adjusting at least one of the heating power and the heating frequency of each atomizer, the mixing ratio of the aerosol of the atomizer device can be changed, thereby meeting different aerosol usage requirements.

[0093] In one embodiment, if the working mode is the cooperative cycle mode, such as Figure 4 As shown, step 106 includes step 406 and step 408 .

[0094] If the working mode is the cooperative cycle mode, let the cooperative cycle be T, the total heating time of each cycle of atomizer 1 is T1 (heating time), the start time of each cycle is t10, and the end time of each cycle is t11; the total heating time of each cycle of atomizer 2 is T2, the start time of each cycle is t20, and the end time of each cycle is t21; ...; the total heating time of each cycle of atomizer n is Tn, the start time of each cycle is tn0, and the end time of each cycle is tn1. The range of T1, T2, ...Tn: 0 ~ T. In the cooperative cycle mode, the output power P_OUT calculation formula is:

[0095] P_OUT = ((V1 2 / R1)*T1+(V2 2 / R2)*T2+…+(Vn 2 / Rn)*Tn) / T (1)

[0096] Among them, V1 is the sampling voltage of the heating element of atomizer 1, R1 is the sampling resistance of the heating element of atomizer 1, and so on, Vn is the sampling voltage of the heating element of atomizer n, and Rn is the sampling resistance of the heating element of atomizer n.

[0097] Step 406 , obtaining the heating cycle of each atomizer according to the coordination cycle, the preset heating power of each atomizer, the sampling resistance and the sampling voltage.

[0098] The coordination period and the preset heating power of each atomizer are pre-set fixed values, and the sampling resistance and the sampling voltage are the sampling values ​​obtained according to step 104. 2 / Rn)*Tn / T, after determining the coordinated period T, the preset heating power P1, P2, ... Pn of each atomizer, the sampling resistor R1, R2, ... Rn, and the sampling voltage V1, V2, ... Vn, the heating period T1, T2, ... Tn of each atomizer can be obtained by combining formula (1).

[0099] Step 408, obtaining the heating time of each atomizer according to the heating cycle and the coordination cycle of each atomizer, and generating a control signal according to the heating time.

[0100] The heating cycle T1, T2, ... Tn of each atomizer is in the range of greater than 0 and less than T, the earliest time point among T1, T2, ... Tn is the starting point of T, and the latest time point among T1, T2, ... Tn is the ending point of T.

[0101] After obtaining the heating cycle and coordination cycle of each atomizer, the heating time of each atomizer can be obtained by combining the heating cycle and coordination cycle of each atomizer. Then, a control signal is generated according to the obtained heating time to control the heating of each atomizer. The heating time of each atomizer obtained here includes the heating start time and the heating end time of each atomizer. It can be understood that the combination of the heating time of each atomizer obtained according to the heating cycle and coordination cycle of each atomizer is not unique, and can also be dynamically adjusted during the control process to better meet customer needs.

[0102] In this embodiment, if the working mode is the collaborative cycle mode, the heating cycle of each atomizer is obtained according to the collaborative cycle, the preset heating power of each atomizer, the sampling resistance and the sampling voltage. The heating time of each atomizer is obtained according to the heating cycle of each atomizer and the collaborative cycle. A control signal is generated according to the heating time, so that a variety of aerosols can be obtained.

[0103] In one embodiment, if the working mode is the cooperative cycle mode, such as Figure 5 As shown, step 106 may also include step 506 and step 508 .

[0104] Step 506 obtains the coordination period according to the total heating power, the heating period of each atomizer, the sampling resistance and the sampling voltage.

[0105] The total heating power and the heating cycle of each atomizer are preset fixed values, and the sampling resistor and the sampling voltage are the sampling values ​​obtained according to step 104. After the total heating power P_OUT, the heating cycle T1, T2, ... Tn of each atomizer, the sampling resistor R1, R2, ... Rn, and the sampling voltage V1, V2, ... Vn are determined, the coordination cycle T can be obtained by combining formula (1).

[0106] Step 508: Obtain the heating time of each atomizer according to the heating cycle and the coordination cycle of each atomizer, and generate a control signal according to the heating time.

[0107] The heating cycle T1, T2, ... Tn of each atomizer is in the range of greater than 0 and less than T, the earliest time point among T1, T2, ... Tn is the starting point of T, and the latest time point among T1, T2, ... Tn is the ending point of T.

[0108] After obtaining the heating cycle and coordination cycle of each atomizer, the heating time of each atomizer can be obtained by combining the heating cycle and coordination cycle of each atomizer. Then, a control signal is generated according to the obtained heating time to control the heating of each atomizer. The heating time of each atomizer obtained here includes the heating start time and the heating end time of each atomizer. It can be understood that the combination of the heating time of each atomizer obtained according to the heating cycle and coordination cycle of each atomizer is not unique, and can also be dynamically adjusted during the control process to better meet customer needs.

[0109] In this embodiment, if the working mode is the collaborative cycle mode, the collaborative cycle is obtained according to the total heating power, the heating cycle of each atomizer, the sampling resistance and the sampling voltage. The heating time of each atomizer is obtained according to the heating cycle of each atomizer and the collaborative cycle. A control signal is generated according to the heating time. The heating time of each atomizer can be controlled to adapt to different aerosol requirements.

[0110] It is understood that step 408 and step 508 are the same steps, but are performed after different steps. Figure 6 As shown, in step 408 or step 508 , the step of obtaining the heating time of each atomizer according to the heating cycle and the coordination cycle of each atomizer includes step 608 .

[0111] Step 608: If the sum of the heating cycles is greater than the coordination cycle, fix the heating end time of each atomizer and determine the heating start time of each atomizer so that the heating time of each atomizer does not overlap.

[0112] Specifically, if the sum of the heating cycles is greater than the coordination cycle, it is considered that the atomizers have overlapping heating times. That is, during the overlapping heating time, at least two atomizers are heated at the same time. At this time, the heating end time of each atomizer can be fixed, and then the heating start time of each atomizer can be determined by combining the heating cycle of each atomizer and the coordination cycle. It can be understood that the heating end time of each atomizer can be set according to actual needs, and in the next coordination cycle, the heating end time of each atomizer different from the current coordination cycle can also be fixed.

[0113] In addition, in step 408 or step 508 , the step of obtaining the heating time of each atomizer according to the heating cycle and the coordination cycle of each atomizer may further include step 610 .

[0114] Step 610: If the sum of the heating cycles is less than the coordination cycle, the heating start time of each atomizer is fixed, and the heating end time of each atomizer is determined.

[0115] Specifically, if the sum of the heating cycles is less than the coordination cycle, there is a waiting time in the coordination cycle. During the waiting time, no atomizer is heated. At this time, the heating start time of each atomizer can be fixed, and then the heating end time of each atomizer can be determined by combining the heating cycle and the coordination cycle of each atomizer. It can be understood that the heating start time of each atomizer can be set according to actual needs, and in the next coordination cycle, the heating start time of each atomizer different from the current coordination cycle can also be fixed.

[0116] In this embodiment, if the sum of the heating cycles is greater than the coordination cycle, the heating end time of each atomizer is fixed, and the heating start time of each atomizer is determined so that the heating time of each atomizer does not overlap. The heating time of each atomizer can be obtained based on the size relationship between each heating cycle and the coordination cycle, so that the obtained heating time is more accurate. In addition, in the use scenario where each atomizer shares a power supply, the non-overlapping heating time means that each atomizer does not use the power of the power supply at the same time, reducing the requirements for the instantaneous power supply capacity of the power supply, protecting the safety of the power supply and the atomizer, and also ensuring the working efficiency of the atomizer.

[0117] It can be understood that in other embodiments, if the sum of the heating cycles is equal to the coordination cycle, considering that there is neither heating overlap time nor waiting time in the coordination cycle, the heating start time of each atomizer can be determined by fixing the heating end time of each atomizer, or the heating end time of each atomizer can be determined by fixing the heating start time of each atomizer, as long as those skilled in the art consider it achievable.

[0118] In one embodiment, if the working mode is the independent cycle mode, such as Figure 7 As shown, step 106 includes step 706 and step 708 .

[0119] If the working mode is independent cycle mode, each atomizer works according to its own heating cycle. In independent cycle mode, the total output power P_OUT is the sum of the power of each atomizer (P1, P2, ... Pn):

[0120] P_OUT = P1+P2+…+Pn (2)

[0121] Wherein, P1 is the power of atomizer 1, and so on, Pn is the power of atomizer n.

[0122] Pn=(Vn 2 / Rn)*duty (3)

[0123] Wherein, Vn is the sampling voltage of the heating element of atomizer n, Rn is the sampling resistance of the heating element of atomizer n, duty is the duty cycle of the control signal for controlling the atomizer, and the control signal may be a PWM signal.

[0124] Step 706 , obtaining the heating frequency of each atomizer according to the preset heating power, sampling resistance and sampling voltage of each atomizer.

[0125] Among them, the preset heating power P1, P2, ... Pn of each atomizer is a pre-set fixed value, and the sampling resistance and the sampling voltage are the sampling values ​​obtained according to step 104. After determining the preset heating power P1, P2, ... Pn, the sampling resistance R1, R2, ... Rn, and the sampling voltage V1, V2, ... Vn of each atomizer, the duty cycle of the control signal of each atomizer can be obtained by combining formula (3). The heating frequency of the atomizer can be obtained according to the duty cycle of the control signal.

[0126] Step 708: Generate a control signal according to the heating frequency.

[0127] After the heating frequency is obtained, a control signal is generated according to the heating frequency to control the heating of each atomizer.

[0128] In this embodiment, if the working mode is the independent cycle mode, the heating frequency of each atomizer is obtained according to the preset heating power, sampling resistance and sampling voltage of each atomizer, and a control signal is generated according to the heating frequency. By adjusting the heating frequency, the purpose of adjusting the richness of the aerosol generated by the atomization device is achieved.

[0129] In one embodiment, if the working mode is the independent cycle mode, such as Figure 8 As shown, step 106 includes step 806 and step 808 .

[0130] Step 806 , obtaining the heating power of each atomizer according to the preset heating frequency, sampling resistance and sampling voltage of each atomizer.

[0131] The preset heating frequencies F1, F2, ... Fn of each atomizer are preset fixed values, and the sampling resistors and sampling voltages are the sampling values ​​obtained according to step 104. The duty cycle duty of the control signal of each atomizer can be obtained according to the preset heating frequencies F1, F2, ... Fn of each atomizer. After obtaining the duty cycle duty of the control signal, the sampling resistors R1, R2, ... Rn, and the sampling voltages V1, V2, ... Vn, the heating power P1, P2, ... Pn of each atomizer can be obtained by combining formula (3).

[0132] Step 808: Generate a control signal according to the heating power.

[0133] After the heating power is obtained, a control signal is generated according to the heating power to control the heating of each atomizer.

[0134] In this embodiment, if the working mode is the independent cycle mode, the heating power of each atomizer is obtained according to the preset heating frequency, sampling resistance and sampling voltage of each atomizer, and a control signal is generated according to the heating power. By adjusting the heating power, the purpose of adjusting the richness of the aerosol generated by the atomization device is achieved.

[0135] In one embodiment, Fig. 9 As shown, after step 104 , the atomization device control method further includes step 904 .

[0136] Step 904: If the atomizer is judged to be abnormal according to the sampling resistance or the sampling voltage, the abnormal atomizer is controlled to stop working.

[0137] It can be understood that as long as the atomizer is judged to be abnormal according to one of the sampling resistance and the sampling voltage, the abnormal atomizer is controlled to stop working.

[0138] The method of judging the abnormality of the atomizer according to the sampling resistance can be: comparing the sampling resistance with a preset lower limit value of resistance, if the sampling resistance is less than the preset lower limit value of resistance, judging that the atomizer has a short circuit abnormality; or comparing the sampling resistance with a preset upper limit value of resistance, if the sampling resistance is greater than the preset upper limit value of resistance, judging that the atomizer has an open circuit abnormality.

[0139] The method of judging the abnormality of the atomizer according to the sampling voltage can be: comparing the sampling voltage with the preset voltage lower limit value, if the sampling resistance is less than the preset voltage lower limit value, it is judged that the atomizer is abnormal. The sampling voltage is the voltage of the heating element of the atomizer, and can also be regarded as the voltage of the battery cell connected to the atomizer.

[0140] If the atomizer is abnormal according to the sampling resistance or the sampling voltage, the abnormal atomizer is controlled to stop working to avoid further damage to other components in the atomizer. In an expandable manner, if the atomizer is abnormal according to the sampling resistance or the sampling voltage, it is further determined whether a stop signal is received. If a stop signal is received, the abnormal atomizer is controlled to stop working. In this way, the demand for aerosol generated by the faulty atomizer within the working cycle can be guaranteed.

[0141] In this embodiment, if the atomizer is judged to be abnormal according to the sampling resistance or the sampling voltage, the abnormal atomizer is controlled to stop working to avoid further damage to other components in the atomizer, thereby improving the safety performance of the atomization device.

[0142] 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 does not have a strict order restriction, and these steps can be executed in other orders.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more atomizer control device embodiments provided below can refer to the limitations of the atomizer control method above, and will not be repeated here.

[0144] In one embodiment, Fig.10 As shown, a control device for an atomizing device is provided, the atomizing device includes at least two atomizers, and the control device for the atomizing device includes: a sampling module 1004, a control signal determination module 1006 and a heating control module 1008, wherein:

[0148] In one embodiment, the atomizer control device further comprises a parameter type determination module, which is used to determine the adjustment parameter type before the control signal determination module determines the control signal corresponding to each atomizer based on the sampling resistance and the sampling voltage.

[0149] In one embodiment, the parameter type determination module is further used to determine the working mode of the atomization device; and determine the adjustment parameter type according to the determined working mode.

[0150] In one embodiment, the working mode includes a collaborative cycle mode and an independent cycle mode, and the parameter type determination module is also used to determine that the adjustment parameter type is heating time if the working mode is the collaborative cycle mode; if the working mode is the independent cycle mode, determine that the adjustment parameter type is at least one of heating power or heating frequency.

[0153] In one embodiment, the control signal determination module is further used to fix the heating end time of each atomizer and determine the heating start time of each atomizer if the sum of the heating cycles is greater than the coordination cycle, so that the heating times of the atomizers do not overlap.

[0154] In one embodiment, if the working mode is an independent cycle mode, the control signal determination module is further used to obtain the heating frequency of each atomizer according to the preset heating power of each atomizer, the sampling resistance and the sampling voltage; and generate a control signal according to the heating frequency.

Each of the above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the corresponding operations of each of the above modules.

[0158] In one embodiment, an aerosol generating device is provided, including a power supply, an atomizing device and a controller connected to the power supply, the atomizing device is connected to the controller, and the controller is used to control the atomizing device according to the method of any of the above method embodiments.

[0159] In one embodiment, each atomizer in the atomization device is connected to the same power source. The same power source is used to power each atomizer, which is beneficial to reducing the volume of the aerosol generating device and improving the portability of the aerosol generating device.

[0160] In one embodiment, the atomization device includes an atomizer, a first heating control circuit and a second heating control circuit connected to a controller, and the atomizer includes a first atomizer and a second atomizer;

[0161] The first heating control circuit is used to control the heating of the first atomizer, and the second heating control circuit is used to control the heating of the second atomizer. The resistance temperature coefficient of the heating element in the first atomizer is different from the resistance temperature coefficient of the heating element in the second atomizer.

[0162] The temperature coefficient of resistance refers to the relative change of resistance value when the temperature changes by 1°C with a specific temperature as the reference value. The unit is ppm / °C. It is generally divided into PTC (Positive Temperature Coefficient), NTC (Negative Temperature Coefficient) and critical temperature coefficient. The specific temperature is the temperature constant, which is generally room temperature, such as 25°C, or any other value within 24°C-26°C.

[0163] Specifically, Fig.11As shown, the first heating control circuit includes a switch tube Q1, a resistor R1, a resistor R2, a resistor R3 and a diode D1. The control end of the switch tube Q1 is connected to the controller through the resistor R1, and the control signal HEAT is connected from the controller. The first end of the switch tube Q1 is connected to the power supply BAT+, and the second end is connected to the cathode of the diode D1 and the first end of the resistor R2. The anode of the diode D1 and the second end of the resistor R2 are grounded, and the first end and the second end of the resistor R2 are connected to the two ends of the heating element of the atomizer through the H+ terminal and the H- terminal respectively. The two ends of the resistor R3 are respectively connected to the control end and the first end of the switch tube Q1. The switch tube Q1 can be a MOS tube. The controller can control the switch tube Q1 to be in an on or off state by sending different control signals to the control end of the switch tube Q1, thereby controlling whether the heating element is heated.

[0164] like Fig.12 As shown, the first heating control circuit includes a switch tube Q2, a switch tube Q3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8 and a diode D2. The control end of the switch tube Q2 is connected to the controller through the resistor R5, and the control signal HEAT is connected from the controller. The first end of the switch tube Q2 is connected to the power supply, and the second end is connected to the cathode of the diode D2. The cathode of the diode D2 and the anode of the diode D2 are connected to the two ends of the heating element of the atomizer through the H+ terminal and the H- terminal, respectively, and the anode of the diode D2 is grounded. The two ends of the resistor R4 are respectively connected to the control end and the first end of the switch tube Q2. The cathode of the diode D2 and the first end of the resistor R7 are both connected to the controller through the resistor R6. The second end of the resistor R7 is connected to the first end of the switch tube Q3, and the second end of the switch tube Q3 is connected to the power supply. The control end of the switch tube Q3 is connected to the controller, and the two ends of the resistor R8 are respectively connected to the control end of the switch tube Q3 and the second end of the switch tube Q3. The switch tube Q2 and the switch tube Q3 can be MOS tubes. The controller can control the switch tube Q2 to be in the on or off state by sending different control signals to the control end of the switch tube Q2, thereby controlling whether the heating element generates heat. The switch tube Q3 and the resistor R7 constitute a resistance detection circuit, which can detect the resistance of the heating element and send it to the controller. It can be understood that in other embodiments, the structures of the first heating control circuit and the second heating control circuit can also be other, as long as those skilled in the art believe that it can be implemented.

[0165] In this embodiment, different heating control circuits are used to control heating elements with different resistance temperature coefficients, thereby meeting the needs of multiple types of heating elements.

[0166] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, the structure of the first heating control circuit is as follows: Fig.11As shown, it can be used to control heating elements with good resistance consistency, good stability, and small TCR (<100ppm). The structure of the second heating control circuit is as follows Fig.12 As shown, it can be used to control heating elements with a wide resistance distribution range, poor stability, and large TCR. The atomization device includes multiple atomizers, each of which performs atomization in a partition. Theoretically, partition atomization can be divided into countless zones (N), but the actual operability is limited, generally divided into 2 zones or 3 zones. The more partitions there are, the more complex the structural design.

[0167] The specific heating method of the atomizer is as follows:

[0168] 1. Collaborative cycle mode: Each partition atomizer works together, and all atomizers complete a cycle together as a cycle, and the collaborative cycle is T (mode 1). The total heating time of atomizer 1 in each cycle is T1 (heating time), the start time of each cycle is t10, and the end time of each cycle is t11; the total heating time of atomizer 2 in each cycle is T2, the start time of each cycle is t20, and the end time of each cycle is t21; ...; the total heating time of atomizer n in each cycle is Tn, the start time of each cycle is tn0, and the end time of each cycle is tn1. At the same time, the time of tn0 can be changed once every cycle according to a certain rule. The range of T1, T2, ...Tn: 0~T. Fig.13 This is a control timing diagram of different atomizers in the coordinated cycle mode. The three curves in the figure represent the control timings of three different atomizers respectively.

[0169] Output power calculation: P_OUT = ((V1 2 / R1)*T1+(V2 2 / R2)*T2+…+(Vn 2 / Rn)*Tn) / T.

[0170] Different tastes can be obtained by adjusting t10, t11 / t20, t21 / … / tn0, tn1.

[0171] The power can be adjusted by adjusting the size of T1, T2...Tn to perform variable power output control.

[0172] 2. Independent cycle mode: Each partition atomizer works according to its own heating cycle (mode 2)

[0173] Each atomizer outputs at its own frequency Fn, which can be constant power Pn, variable power, or even variable frequency output. Fig.14 This is a control timing diagram of different atomizers in independent cycle mode. The two curves in the figure represent the control timing of two different atomizers.

[0174] The total output power is the sum of the power of each atomizer: P_OUT = P1 + P2 + ... + Pn

[0175] Pn=(Vn 2 / Rn)*duty, Vn is the load voltage of the heating element, Rn is the real-time resistance of the heating element, and duty is the PWM pulse duty cycle.

[0176] like Fig.15 As shown, the atomization device control method includes:

[0177] First, before puffing, select the working mode (mode 1 or mode 2) and set the relevant parameters of each output channel (power, time, frequency, etc.). When the puffing action triggers the microphone to start, and after detecting the start signal, first collect the resistance value of each heating element and the battery voltage, then determine the current working mode, and output the control signal of each channel according to the working mode and specific setting parameters.

[0178] During the output process, the resistance of the heating element and the voltage of the battery cell in each partition are detected, and the variable is adjusted in real time according to the invariant (such as power) in the set parameters. The resistance of the heating element is used to determine whether it is short-circuited (the resistance is less than the preset lower limit of the resistance) or open-circuited (the resistance is greater than the preset upper limit of the resistance), and the voltage of the battery cell is used to determine whether it is low voltage (the battery cell voltage is lower than the preset lower limit of the voltage). When the suction stops, the heating output of each channel is immediately stopped.

[0179] In mode 1, constant power output is adopted (P is fixed) and the period T is also fixed. The values ​​of P1, P2…Pn can be fixed and the values ​​of t10, t11 / t20, t21 / … / tn0, tn1 can be adjusted according to the power of each partition (t11, t21,…tn1 is fixed and t10, t20,…tn0 is changed) to change T1, T2…Tn. Alternatively, T1, T2,…Tn can be fixed and the values ​​of t10, t11 / t20, t21 / … / tn0, tn1 can be adjusted according to the power of each partition (t10, t20,…tn0 is changed to change the size of T).

[0180] The specific implementation can be as follows:

[0181] First, preset P, T, P1...Pn; then obtain R1...Rn, V1...Vn through real-time sampling; T1 can be calculated through V1, R1, P1, and so on to calculate T2...Tn.

[0182] If T1+T2…Tn>T, t21…tn1 can be fixed to determine t10, t11 / t20, t21 / … / tn0, tn1;

[0183] If T1+T2…Tn<T, t20…tn0 can be fixed, thereby determining t10, t11 / t20, t21 / … / tn0, tn1.

[0184] In mode 2, constant power output is adopted (fixed P remains unchanged). The power P1, P2...Pn and frequency F1, F2...Fn of each partition can be fixed unchanged, and the duty of each partition can be adjusted separately; or the total output power P can be kept unchanged, and the size of P1, P2...Pn can be dynamically adjusted according to the rules, and then the duty of each partition can be adjusted according to the rules of this partition).

[0185] The specific operations are as follows:

[0186] First preset P1, P2...Pn, and the output frequency F1, F2...Fn of each partition;

[0187] R1…Rn, V1…Vn are obtained by real-time sampling during the heating process;

[0188] Finally, the duty cycle of each partition is calculated based on the above parameters to form a new control curve.

[0189] The above-mentioned atomization device control method controls the output power by controlling the heating output timing of multiple atomizers, and adjusts different aerosols through different timings. The multiple atomizers reasonably reduce the heating time of each atomizer through timing control, delay aging, and reduce the scaling rate. In addition, the partitioned atomization heating control mode is optional, the key parameters of the heating control are adjustable, and a variety of optional output modes can be provided.

Thus, based on the sampling resistance and sampling voltage of each atomizer, a corresponding control signal is obtained, and the atomizer is controlled according to the control signal, so that the control of the atomizer can be adjusted according to the actual working state of the atomizer, which is conducive to improving the accuracy of controlling the atomizer, optimizing the atomization parameters of the atomizer, so that the atomizer meets the preset working state, and can also diversify the control method, and each atomizer can generate different aerosols, so that the atomizer can generate aerosols of different types and different mixing ratios, meet the diversified aerosol use needs, and improve the working reliability of the atomizer.
