[0047] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to 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.

[0048] The atomizing device control method provided by the embodiments of the present application is used to control an atomizing device, and specifically can be used to control the working state and working mode of the atomizing device. Generally, the atomizing device includes a power supply module, a control module, an output control module, and a heating element. Among them, the power supply module is connected to the control module and the output control module, and is used to supply power to the control module and the output control module. The type of the heating element is not limited. For example, it can be a heating wire, a heating coil, or a heating sheet, etc. Exemplarily, the heating element in this embodiment can be a mesh heating wire, which is obtained by processing a stainless steel sheet into a mesh shape through an etching process. The number of heating elements is at least two, and different heating elements are correspondingly connected to different output control modules. One output control module is correspondingly connected to one heating element, and each heating element can be controlled separately, so that the working states of the heating elements do not interfere with each other. Each output control module is connected to the control module, and the control module can control the working state of each output control module, thereby controlling the working state of the heating element connected to the output control module. Exemplarily, when the control module controls the output control module to conduct, the heating element can be powered on through the output control module and start working, starting to heat up. When the control module controls the output control module to disconnect, the heating element loses power and stops heating.

[0049] The atomizing device control method can be executed by the control module of the atomizing device. The control module can realize the working control of the heating element by controlling the working state of the output control module, and can also control the working state of other structures, which will not be elaborated here. It can be understood that in other embodiments, the atomizing device control method can also be executed by a terminal or a server in communication connection with the atomizing device, and data interaction can be carried out with the atomizing device. Among them, the terminal can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices, and the server can be realized by an independent server or a server cluster composed of multiple servers.

[0050] In one embodiment, as Figure 1 shown, an atomizing device control method is provided. Taking the method being executed by the control module as an example, it includes the following steps:

[0051] Step 102, obtain the power level parameter of the atomizing device.

[0052] Among them, the power level parameter is generally the power level parameter of the power supply module of the atomizing device, and is used to characterize the current power level of the atomizing device. The power level parameter can be a specific power value, or the percentage of the current remaining power to the rated power, which is not limited here. Exemplarily, in this embodiment, the power supply module includes a battery, and the power level parameter can be the percentage of the remaining power of the battery to the rated power.

[0053] Step 104, if the power level parameter is less than the preset threshold, control the atomization device to operate in the single heating element mode.

[0054] Among them, the preset threshold is the comparison object of the power level parameter and has the same type as the power level parameter. For example, if the power level parameter is a percentage, the preset threshold is also a percentage. According to the magnitude relationship between the power level parameter and the preset threshold, the power state of the atomization device can be judged, and based on this, the atomization device can be controlled to be in different working modes. The value of the preset threshold is not unique and can be determined according to the selection of the power supply module. For example, it can be 60% or 70%, etc.

[0055] If the power level parameter is less than the preset threshold, considering that the current power of the atomization device is not sufficient, at this time, control the atomization device to operate in the single heating element mode. In the single heating element mode, one heating element in the atomization device works. In the single heating element mode, only one heating element works at the same time, and the heating intensity is small, which can better achieve the oil-electricity matching. Avoid in the case of insufficient power, the heating intensity is too large, resulting in too fast power consumption, so that the aerosol generation matrix cannot be completely atomized after the power is exhausted, causing waste of resources.

[0056] Among them, the oil-electricity matching is a desired state, which means that according to the user's needs, it is expected to match the battery power with the amount of aerosol generation matrix, that is, when the battery power is used up, the aerosol generation matrix is also used up.

[0057] Step 106, if the power level parameter is greater than or equal to the preset threshold, control the atomization device to operate in the multi-heating element mode.

[0058] If the power level parameter is greater than or equal to the preset threshold, considering that the current power of the atomization device is sufficient, at this time, control the atomization device to operate in the multi-heating element mode. In the multi-heating element mode, at least two heating elements in the atomization device work simultaneously. In the multi-heating element mode, at least two heating elements work simultaneously at the same time. Further, the working heating elements are the heating elements connected to different output control modules. The number of working heating elements can be determined according to actual needs. For example, if the atomization device includes two heating elements, the number of working heating elements in the multi-heating element mode is two. If the atomization device includes three heating elements, the number of working heating elements in the multi-heating element mode can be two or three. It can be understood that the number of working heating elements in the multi-heating element mode is not unique and can be determined according to actual needs.

[0059] If the power level parameter is greater than or equal to the preset threshold, control the atomization device to operate in the multi-heating element mode. At this time, the power is sufficient and the heating intensity is large, which can better achieve the oil-electricity matching. Avoid in the case of sufficient power, the heating intensity is too small, resulting in too slow power consumption, so that the aerosol generation matrix is completely atomized before the power is exhausted, causing waste of power.

[0060] The above-mentioned atomizing device control method, the atomizing device includes at least two heating elements, and the method includes: obtaining the power level parameter of the atomizing device, if the power level parameter is less than the preset threshold, controlling the atomizing device to work in the single heating element mode, in the single heating element mode, one of the heating elements in the atomizing device works, if the power level parameter is greater than or equal to the preset threshold, controlling the atomizing device to work in the multi-heating element mode; in the multi-heating element mode, at least two heating elements in the atomizing device work simultaneously. By controlling the atomizing device to work in different modes according to the magnitude of the power level parameter of the atomizing device, different numbers of heating elements work, and the heating degree can be matched according to the power level parameter, so as to match the atomizing amount, which can effectively solve the problem of mismatch between oil and electricity of the traditional dual heating wire atomizing device and improve the working performance of the atomizing device.

[0061] In one embodiment, as Figure 2 shown, in step 104, the step of controlling the atomizing device to work in the single heating element mode includes step 202 and step 204.

[0062] Step 202, within different time periods, sequentially control one heating element in each heating element to work.

[0063] Among them, the heating elements working in different time periods are different. The durations of different time periods can be the same or different, and are determined according to the actual situation. The specific duration of the time period can be determined through experiments and stored as a preset value in the control module. It can also be flexibly adjusted according to the received user instructions.

[0064] Taking the number of heating elements as two, including heating element 1 and heating element 2, and the number of output control modules as two, including output control module 1 and output control module 2, with output control module 1 connected to heating element 1 and output control module 2 connected to heating element 2 as an example, if the power level parameter is less than the preset threshold, then control the atomizing device to work in the single heating element mode. Within different time periods, sequentially control one heating element in each heating element to work. Then, within the first time period (for example, 5 ms), the control module first controls output control module 1 connected to heating element 1 to output, so that heating element 1 works, and obtain the working duration Ta of heating element 1. After the working duration Ta of heating element 1 reaches the duration of the first time period, within the second time period (for example, 5 ms), the control module then controls output control module 2 connected to heating element 2 to output, so that heating element 2 works, and obtain the working duration Tb of heating element 2. After the working duration Tb of heating element 2 reaches the duration of the second time period, stop working.

[0065] Step 204, if the total working duration of each heating element is greater than the preset total duration threshold, control each heating element to stop working.

[0066] Among them, the preset total duration threshold is used to represent the expected heating duration, which can be determined according to experiments or experience, or can be flexibly adjusted according to the received user instructions. Exemplarily, in this embodiment, the preset total duration threshold is 8s.

[0067] During the working process of each heating element, the control module will record the working duration of each heating element and add up the working durations of each to obtain the total working duration of the heating elements. If the total working duration of the heating elements is greater than the preset total duration threshold, considering that the working duration has met the requirements, the control module will control each heating element to stop working.

[0068] In this embodiment, within different time periods, one heating element in each heating element is controlled to work in turn, and different heating elements are controlled to work in different time periods until the total working duration of the heating elements is greater than the preset total duration threshold, and then the control module will control each heating element to stop working. Controlling one heating element to work each time can effectively limit the heating intensity. When the total working duration of the heating elements is greater than the preset total duration threshold, considering that the atomizing device has completed the target work task, the control module will control each heating element to stop working to avoid waste of resources.

[0069] In one embodiment, as Figure 3 shown, in step 104, the steps of controlling the atomizing device to work in the single heating element mode include step 302 and step 304.

[0070] Step 302, controlling each heating element to work alternately.

[0071] Among them, each heating element working alternately means that each heating element works in different time periods respectively, and the working time period of one heating element includes non-adjacent time periods.

[0072] Taking the number of heating elements as two, including heating element 1 and heating element 2, and the number of output control modules as two, including output control module 1 and output control module 2, where output control module 1 is connected to heating element 1 and output control module 2 is connected to heating element 2 as an example, if the power level parameter is less than the preset threshold, the control module will control the atomizing device to work in the single heating element mode and control each heating element to work alternately. As Figure 4As shown, within the first sub-time period Ta1 of the heating element 1, the control module first controls the output control module 1 connected to the heating element 1 to output, causing the heating element 1 to operate. Then, within the first sub-time period Tb1 of the heating element 2, the control module controls the output control module 2 connected to the heating element 2 to output, causing the heating element 2 to operate. Then, within the second sub-time period Ta2 of the heating element 1, the control module controls the output control module 1 connected to the heating element 1 to output, causing the heating element 1 to operate. Then, within the second sub-time period Tb2 of the heating element 2, the control module controls the output control module 2 connected to the heating element 2 to output, causing the heating element 2 to operate, and so on. In the order of the time axis, it is successively the first sub-time period of the heating element 1, the first sub-time period of the heating element 2, the second sub-time period of the heating element 1, the second sub-time period of the heating element 2, and so on.

[0073] Step 304, if the sum of the cumulative operation durations of the heating elements is greater than the preset total duration threshold, control each heating element to stop operating.

[0074] Among them, the cumulative operation duration of the heating element refers to the sum of the different sub-time periods of the operation of each heating element. By summing up the cumulative operation durations of the heating elements, the sum of the cumulative operation durations of each heating element is obtained. The preset total duration threshold is used to represent the desired heating duration, which can be determined based on experiments or experience, or can be flexibly adjusted according to the received user instructions. Exemplarily, in this embodiment, the preset total duration threshold is 8s.

[0075] During the operation of each heating element, the control module will record the duration of each sub-time period of the operation of each heating element, add up the durations of each sub-time period, and then add up the durations of each sub-time period corresponding to each heating element to obtain the sum of the cumulative operation durations of each heating element. If the sum of the cumulative operation durations of each heating element is greater than the preset total duration threshold, considering that the operation duration has met the requirements, control each heating element to stop operating.

[0076] In this embodiment, control each heating element to operate alternately. If the sum of the cumulative operation durations of each heating element is greater than the preset total duration threshold, control each heating element to stop operating. Controlling each heating element to operate alternately can avoid abnormal situations such as excessive temperature caused by too long heating duration of the heating element. When the sum of the cumulative operation durations of each heating element is greater than the preset total duration threshold, considering that the atomizing device has completed the target operation task, control each heating element to stop operating to avoid waste of resources.

[0077] In one embodiment, as Figure 5 shown, after step 102, the atomizing device control method further includes step 502 and step 504.

[0078] Step 502: If the power level parameter is less than the preset power threshold, control the atomizing device to operate in a boost mode.

[0079] If the power level parameter is less than the preset power threshold, considering that the current power is low, the power of the heating element may be too small. In this case, control the atomizing device to operate in a boost mode to increase the operating power of the heating element and avoid too rapid a decrease in the power of the heating element.

[0080] The preset power threshold can be equal to the preset threshold. In this case, if the power level parameter is less than the preset power threshold, the atomizing device will probably operate in a single heating element mode. The heating power in the single heating element mode is small. In this case, control the atomizing device to operate in a boost mode. By boosting the voltage, the operating power of the heating element can be increased, effectively solving the problem of interrupted suction caused by the switching delay in the single heating element operating mode.

[0081] The preset power threshold can also be greater than the preset threshold. In this case, if the power level parameter is greater than the preset threshold and less than the preset power threshold, the control module will control the atomizing device to operate in a dual heating element mode. In this case, control the atomizing device to operate in a boost mode. By boosting the voltage, the operating power of the heating element can be increased, effectively solving the problems of serious attenuation of the taste during suction use when the power is low and the exacerbation of the switching discontinuity during the switching of the heating element operation.

[0082] The method of controlling the atomizing device to operate in a boost mode is not the only one. Exemplarily, a boost circuit is provided in the atomizing device. The boost circuit is connected to the heating element and the control module. The control module can control the atomizing device to operate in a boost mode by controlling the operation of the boost circuit.

[0083] It can be understood that in other embodiments, the atomizing device can also be controlled to operate in a boost mode according to the detected signal. For example, when a boost instruction sent by the user is received, considering that the user wants to increase the heating power at this time, the control module can also control the atomizing device to operate in a boost mode to increase the heating power, increase the atomization amount or atomization rate, etc., to meet the user's needs.

[0084] Step 504: If the power level parameter is greater than or equal to the preset power threshold, control the atomizing device to operate in a direct-conduction chopper mode.

[0085] Among them, the direct-conduction chopper mode refers to the operating mode in which the atomizing device converts the input power supply voltage into a voltage corresponding to the control signal according to the control signal of the control module. The voltage provided for the heating element in the boost mode is greater than the voltage provided for the heating element in the direct-conduction chopper mode. Generally speaking, the power of the heating element in the boost mode is greater than the power of the heating element in the direct-conduction chopper mode.

[0086] If the power level parameter is greater than or equal to the preset power threshold, considering that the current power is relatively high, no further voltage boost is required for the heating element. In this case, control the atomization device to operate in the direct-through chopping mode, and let the atomization device work according to the default working procedure or user requirements.

[0087] The method of controlling the atomization device to operate in the direct-through chopping mode is not unique. Exemplarily, a direct-through chopping circuit is provided in the atomization device. The direct-through chopping circuit is connected to the heating element and the control module. The control module can control the atomization device to operate in the direct-through chopping mode by controlling the working state of the direct-through chopping circuit.

[0088] In this embodiment, by controlling the atomization device to operate in different modes according to the magnitude relationship between the power level parameter and the preset power threshold, the working performance of the atomization device can be fully guaranteed. When the power level parameter is greater than or equal to the preset power threshold, control the atomization device to operate in the direct-through chopping mode to achieve on-demand operation. When the power level parameter is less than the preset power threshold, control the atomization device to operate in the voltage boost mode, which is beneficial to solve the problems of interrupted suction caused by switching delay in the single heating element mode, and the problems of taste attenuation and aggravated single heating element switching delay when the battery power is low in the dual heating element mode. It can improve the atomization quality of the atomization device and better meet the user's needs.

[0089] In one embodiment, as Figure 6 shown, in step 106, the steps of controlling the atomization device to operate in the multi-heating element mode include step 602 and step 604.

[0090] Step 602, at the same moment, control at least two of the heating elements to work simultaneously.

[0091] At the same moment, control at least two of the heating elements to work simultaneously. Further, the working heating elements include the heating elements connected to different output control modules. The number of working heating elements can be determined according to actual needs. For example, if the atomization device includes two heating elements, the number of working heating elements in the multi-heating element mode is two. If the atomization device includes three heating elements, the number of working heating elements in the multi-heating element mode can be two or three. It can be understood that the number of working heating elements in the multi-heating element mode is not unique and can be determined according to actual needs.

[0092] Step 604, if the heating start duration is greater than the preset total duration threshold, control each heating element to stop working.

[0093] Among them, the heating start duration refers to the duration from the heating start moment to the current timing moment. The preset total duration threshold is used to represent the desired heating duration, which can be determined according to experiments or experience, or can be flexibly adjusted according to the received user instructions. Exemplarily, in this embodiment, the preset total duration threshold is 8s.

[0094] During the working process of each heating element, the control module will record the heating start duration and compare it with the preset total duration threshold. If the heating start duration is greater than the preset total duration threshold, considering that the working duration has met the requirements, the control module will control each heating element to stop working.

[0095] In this embodiment, at the same moment, at least two of the heating elements are controlled to work simultaneously, so as to match a larger consumption of the aerosol generating matrix with a larger amount of electricity, promoting the matching of oil and electricity. Until the heating start duration is greater than the preset total duration threshold, considering that the atomizing device has completed the target work task, the control module will control each heating element to stop working to avoid waste of resources.

[0096] In one embodiment, as Figure 7 shown, before step 102, the atomizing device control method further includes step 701.

[0097] Step 701, determine whether a heating start signal is received.

[0098] If so, execute step 102. The heating start signal is used to represent the heating demand. If a heating start signal is received, considering that the user has a heating demand for the atomizing device at this time, the subsequent steps can be executed to further optimize the control of the working process of the atomizing device.

[0099] Among them, the type of the heating start signal is not unique. For example, it can be a start signal sent by the user through the information interaction module. The information interaction module is connected to the control module, and the type of the information interaction module is not limited. For example, it can be a button or a touch screen, etc. Exemplarily, taking the information interaction module as a button, if the user presses the button and the control module receives the signal that the button is pressed, it is considered that a heating start signal is received.

[0100] Alternatively, the heating start signal can also be a suction signal. The suction signal can be detected by an airflow sensor and then transmitted to the control module. The airflow sensor can be arranged in the suction channel of the atomizing device. Exemplarily, when the user has a suction action on the atomizing device, the airflow sensor detects the suction signal and sends the suction signal to the control module. After the control module receives the suction signal, it can be considered that a heating start signal is received.

[0101] In this embodiment, after receiving the heating start signal, the subsequent control steps are executed, which can realize the on-demand start of the atomizing device.

[0102] In one embodiment, the method for controlling an atomizing device further includes the step of: during the operation of the heating element, if a heating stop signal is received, controlling each heating element to stop operating.

[0103] Wherein, the heating stop signal is used to represent the heating stop requirement. The type of the heating stop signal is not unique. For example, it can be a signal opposite to the heating start signal. Exemplarily, the heating stop signal can be a start signal sent by the user through the information interaction module. The information interaction module is connected to the control module, and the type of the information interaction module is not limited. For example, it can be a button or a touch screen, etc. Taking the information interaction module as a button as an example, if the user releases the button and the control module receives the signal that the button is released, it is considered that the heating stop signal is received.

[0104] Exemplarily, the heating start signal can also be a suction signal. After the suction signal is detected by the airflow sensor, it is transmitted to the control module. The airflow sensor can be arranged in the suction channel of the atomizing device. Exemplarily, when the user stops the suction action on the atomizing device, the airflow sensor cannot detect the suction signal. If the control module does not receive the suction signal transmitted by the airflow sensor, it can be considered that the heating stop signal is received.

[0105] In this embodiment, during the operation of the heating element, if a heating stop signal is received, considering that the atomizing device does not need to be heated at this time, controlling each heating element to stop operating, and timely controlling the atomizing device to stop heating to meet the requirement, and also reducing resource waste.

[0106] For the above method for controlling an atomizing device, the atomizing device includes at least two heating elements, and the method includes: obtaining the power level parameter of the atomizing device. If the power level parameter is less than the preset threshold, controlling the atomizing device to operate in a single heating element mode. In the single heating element mode, one heating element in the atomizing device operates. If the power level parameter is greater than or equal to the preset threshold, controlling the atomizing device to operate in a multi-heating element mode; in the multi-heating element mode, at least two heating elements in the atomizing device operate simultaneously. Controlling the atomizing device to operate in different modes according to the size of the power level parameter of the atomizing device, so that different numbers of heating elements operate, and the heating degree can be matched according to the power level parameter, thereby matching the atomizing amount, which can effectively solve the problem of oil-electricity mismatch of the traditional dual heating wire atomizing device and improve the working performance of the atomizing device.

[0107] In one embodiment, an atomizing device is provided, such as Figure 8As shown in the figure, the atomization device includes a power supply module 100, a control module 200, an output control module 300, and a heating element 400. The number of heating elements 400 is at least two, and different heating elements 400 are correspondingly connected to different output control modules 300. The power supply module 100 and each output control module 300 are both connected to the control module 200, and the control module 200 is used to implement the method of any of the above embodiments.

[0108] Among them, the power supply module 100 is connected to the control module 200 and the output control module 300, and is used to supply power to the control module 200 and the output control module 300. The type of the heating element 400 is not limited. For example, it can be a heating wire, a heating coil, a heating sheet, etc. Exemplarily, the heating element 400 in this embodiment can be a mesh heating wire, and the mesh heating wire is obtained by processing a stainless steel sheet into a mesh shape through an etching process. The number of heating elements 400 is at least two, and different heating elements 400 are correspondingly connected to different output control modules 300. One output control module 300 is correspondingly connected to one heating element 400, and each heating element 400 can be controlled separately, so that the working states of the heating elements 400 do not interfere with each other. Each output control module 300 is connected to the control module 200, and the control module 200 can control the working state of each output control module 300, thereby controlling the working state of the heating element 400 connected to the output control module 300. Exemplarily, when the control module 200 controls the output control module 300 to conduct, the heating element 400 can be powered on through the output control module 300 and start to heat. When the control module 200 controls the output control module 300 to disconnect, the heating element 400 loses power and stops heating.

[0109] In one embodiment, as Figure 9 shown, the output control module 300 includes a direct-through chopper circuit 310 and a boost circuit 320 connected to the control module 200. The direct-through chopper circuit 310 and the boost circuit 320 are both connected to the heating element 400. The control module 200 is used to control both the direct-through chopper circuit 310 and the boost circuit 320 to work when the power level parameter of the atomization device is less than a preset power threshold. The control module 200 is further used to control the direct-through chopper circuit 310 to work and control the boost circuit 320 to stop working when the power level parameter of the atomization device is greater than or equal to the preset power threshold.

[0110] Specifically, when the power level parameter of the atomizing device is less than the preset power threshold, the control module 200 controls both the direct-conversion chopper circuit 310 and the boost circuit 320 to operate. The voltage boosted by the boost circuit 320 is transmitted to the heating element 400 through the direct-conversion chopper circuit 310, playing a boosting role. If the power level parameter is less than the preset power threshold, considering the relatively low current power, the power of the heating element 400 may be too small. In this case, controlling both the direct-conversion chopper circuit 310 and the boost circuit 320 to operate enables the atomizing device to operate in a boost mode, increasing the operating power of the heating element 400 and preventing the power of the heating element 400 from dropping too quickly.

[0111] The control module 200 is further configured to control the direct-conversion chopper circuit 310 to operate and the boost circuit 320 to stop operating when the power level parameter of the atomizing device is greater than or equal to the preset power threshold. Until the chopper circuit converts the connected power supply voltage into a voltage corresponding to the control signal according to the control signal of the control module 200 and then applies it to the heating element 400. If the power level parameter is greater than or equal to the preset power threshold, considering the relatively high current power, further boosting of the heating element 400 may not be necessary. In this case, controlling the direct-conversion chopper circuit 310 to operate and the boost circuit 320 to stop operating enables the atomizing device to operate in a direct-conversion chopper mode, and the atomizing device can operate according to the default operating procedure or user requirements.

[0112] In this embodiment, by controlling the direct-conversion chopper circuit 310 and the boost circuit 320 according to the magnitude relationship between the power level parameter and the preset power threshold, enabling the atomizing device to operate in different modes can fully guarantee the operating performance of the atomizing device and better meet user requirements.

[0113] In one embodiment, as Figure 10 shown, the direct-conversion chopper circuit 310 includes an output switching transistor Q1 and an output circuit. The control terminal of the output switching transistor Q1 is connected to the control module 200, the first terminal of the output switching transistor Q1 is connected to the power supply module 100, and the second terminal of the output switching transistor Q1 is connected to the heating element 400 through the output circuit. In the figure, the B+ and B- terminals are connected to the power supply module, and the H+ and H- terminals are respectively connected to both ends of a heating element.

[0114] The control module 200 can send a control signal to the control terminal of the output switching transistor Q1. The control signal can be a PWM wave signal to control the on-off state of the output switching transistor Q1. When the output switching transistor Q1 is turned on, the electrical energy of the power supply connected to the first terminal of the output switching transistor Q1 passes through the first switching transistor and then is transmitted to the heating element 400 through the output circuit, enabling the heating element 400 to be powered on and operate. At this time, the atomizing device operates in a direct-conversion chopper mode.

[0115] Specifically, the structure of the output circuit is not unique. For example, the output circuit includes an output inductor L1 and an output diode D1. One end of the output inductor L1 is connected to the second end of the output switching transistor Q1, the other end of the output inductor L1 is connected to the anode of the output diode D1, and the cathode of the output diode D1 is connected to the heating element 400. When the output switching transistor Q1 is turned on, the electrical energy of the power supply connected to the first end of the output switching transistor Q1 reaches the output inductor L1 after passing through the first switching transistor. After the inductive action, it is transmitted to the heating element 400 through the output diode D1, enabling the heating element 400 to be powered on and work. It can be understood that in other embodiments, the structures of the output circuit and the direct-through chopper circuit 310 can also be other as long as those skilled in the art believe it can be implemented.

[0116] In this embodiment, the direct-through chopper circuit 310 includes an output switching transistor Q1 and an output circuit. The control end of the output switching transistor Q1 is connected to the control module 200, the first end of the output switching transistor Q1 is connected to the power supply module 100, the second end of the output switching transistor Q1 is connected to the heating element 400 through the output circuit, and the control module 200 can control the working state of the heating element 400 by controlling the on-off state of the output switching transistor Q1, thereby controlling the operation of the atomization device. For example, it controls whether the atomization device operates in the direct-through chopper mode.

[0117] In one embodiment, as Figure 10 shown, the boost circuit 320 includes a boost control switching transistor Q2, a boost capacitor C1, and a boost diode D3. The cathode of the boost diode D3 is connected to the first end of the output circuit, the anode of the boost diode D3 is connected to the first end of the boost capacitor C1, the second end of the boost capacitor C1 is connected to the second end of the output circuit, the control end of the boost control switching transistor Q2 is connected to the control module 200, the first end of the boost control switching transistor Q2 is connected to the output circuit, and the second end of the boost control switching transistor Q2 is grounded.

[0118] The control module 200 can send a control signal to the control end of the boost control switching transistor Q2. The control signal can be a PWM wave signal to control the on-off state of the boost control switching transistor Q2. When the boost control switching transistor Q2 is turned on, the output circuit is grounded, and the boost capacitor C1 and the boost diode D3 are not in use, and the atomization device can operate in the direct-through chopper mode. When the boost control switching transistor Q2 is turned off, the boost capacitor C1, the boost diode D3, and the output circuit form a loop, which plays a boosting role, and the atomization device can operate in the boost mode.

[0119] Further, taking the output circuit including an output inductor L1 and an output diode D1 as an example, the first end of the output circuit refers to the common end of the output inductor L1 and the output switching transistor Q1, which is connected to the cathode of the boost diode D3. The second end of the output circuit refers to the cathode of the output diode D1, which is connected to the second end of the boost capacitor C1. The first end of the boost control switching transistor Q2 is connected to the output circuit, which means that the first end of the boost control switching transistor Q2 is connected to the common end of the output circuit. The common end of the output circuit is the common end of two devices in the output circuit, that is, the common end of the output inductor L1 and the output diode D1.

[0120] In this embodiment, the boost circuit 320 includes a boost control switching transistor Q2, a boost capacitor C1, and a boost diode D3. The cathode of the boost diode D3 is connected to the first end of the output circuit, the anode of the boost diode D3 is connected to the first end of the boost capacitor C1, the second end of the boost capacitor C1 is connected to the second end of the output circuit, the control end of the boost control switching transistor Q2 is connected to the control module 200, the first end of the boost control switching transistor Q2 is connected to the output circuit, and the second end of the boost control switching transistor Q2 is grounded. The control module 200 can control whether the boost circuit 320 realizes the boost function by controlling the on-state of the boost control switching transistor Q2, so as to control whether the atomizing device operates in the boost mode.

[0121] In one embodiment, the atomizing device further includes a display module connected to the control module 200, and each display module is respectively connected to a different heating element 400. The operating states and the like of different heating elements 400 during operation can be displayed through different display modules, and the display effect is intuitive.

[0122] Specifically, the type of the display module is not unique. For example, it can be a display lamp. Through the number of display lamps, the remaining power and working time, etc. of the corresponding heating element 400 during operation can be prompted, which is convenient for the user to better monitor the operating state of the atomizing device. It can be understood that in other embodiments, the type and function of the display module can also be other as long as those skilled in the art think it can be realized.

[0123] To better understand the above embodiments, a specific embodiment will be described in detail below. Since the existing dual heating wire control technology is not yet mature and stable, in the long-term dual heating wire working mode, it is easy to cause the problem of oil-electricity mismatch. Its control in the single heating wire mode of switching the heating wire based on a fixed number of puffs has an unsatisfactory effect. When switching the heating wire based on the cumulative heat generation of the heating wire, there is a short difference or delay at the moment of switching, which easily leads to intermittent puffs and poor user experience. In addition, the existing dual heating wire control schemes do not support the boost scheme, resulting in a serious attenuation of the taste when sucking at low battery power, and the switching break difference of the dual heating wire control in the single heating wire mode is aggravated. To address the above problems, the present application provides a control method and an atomizing device for an atomizing device, aiming to solve the oil-electricity matching problem in the dual heating wire mode of the dual heating wire control scheme, as well as the delay problem and the output working mode problem of the heating wire during the switching of the heating wire in the single heating wire mode, so as to improve the sucking taste and user experience effect.

[0124] In one embodiment, as Figure 11 shown, the atomizing device includes a power supply module, a control module, an output control module, a heating element, an information interaction module, and a display module. Among them, the control module is an MCU control module, the information interaction module is a button module, the output control module includes an output control module 1 and an output control module 2, and the heating element is a heating wire, including a heating wire 1 and a heating wire 2.

[0125] The power supply module is used to supply power to the entire circuit and provide sufficient electrical energy to the output control module. The MCU control module is used to receive external instructions and execute processing instructions. The display module is used to display the switching prompt of the single and dual heating wire modes, the sucking effect prompt, and the power level and other prompts. The button module is used to obtain external output control instructions, single and dual heating wire mode switching instructions, and other operation instructions. The output control module is used to execute the output control instructions to adjust the output scheme and obtain the resistance value of the heating wire. The heating wire module is a resistance wire of a MESH network, which is used to heat the aerosol generating matrix in the atomizing cotton.

[0126] As Figure 12As shown, the process of the atomization device control method includes: First, the button module or an external switch (such as an airflow sensor) obtains an external operation instruction. After the MCU control module 200 obtains the external operation instruction, it starts to process information and perform internal related detections. If it is determined that the button is in the long-press state KEY = 1 or the microphone is in the suction state MIC = 1, and the detected battery power level parameter BAT_LEV < the preset threshold Volt_percent, then the atomization device is controlled to operate in the single heating element mode, specifically it can be the single heating wire mode, assign M_Mode = 1, and execute the output control instruction and the output timing instruction T++. The MCU control module 200 adjusts the output control module 1 and the heating wire 1 to perform output, and the output time Ta of the output control module 1 and the heating wire 1 is incremented. When the output time Ta of the output control module 1 and the heating wire 1 >= 5ms, Ta is cleared. Thereafter, the MCU control module 200 adjusts the output control module 2 and the heating wire 2 to perform output, and the output time Tb of the output control module 2 and the heating wire 2 is incremented. When the output time Tb of the output control module 2 and the heating wire 2 > 5ms, Tb is cleared; at the same time, the display module (8 white LEDs, 4 LEDs 1-LED4 corresponding to the heating wire 1, and 4 LEDs 5-LED8 corresponding to the heating wire 2) alternately breathes and prompts in the form of the LEDs corresponding to the heating wire in the power state to prompt the suction state. The MCU control module 200 controls its execution output in this loop. When the button state KEY = 0 or the microphone suction state MIC = 0 or the total suction time T = 8S (suction timeout), the MCU control module 200 exits the output loop program to turn off the output, and the LED display module is turned off.

[0127] If it is determined that the battery power level parameter BAT_LEV of the current battery >= the preset threshold Volt_percent, then the MCU control module 200 controls the atomization device to jump to the multi-heating element mode, specifically it can be the dual heating wire working mode, assign M_Mode = 2. The MCU control module 200 simultaneously controls the two output control modules 300 and the two heating wires to work simultaneously. The two groups of LEDs corresponding to the two heating wires of the LED display module simultaneously breathe and flash in the power level to prompt the output. When the button state KEY = 0 or the microphone suction state MIC = 0 or the total suction time T = 8S (suction timeout), the output is turned off, and the LED display module is turned off. Among them, Volt_percent can be the voltage percentage, set to 70%, and can be set according to the selection of the battery cell in actual design.

[0128] Such as Figure 10As shown, the output control module 300 includes a direct-conduction chopper circuit 310 and a boost circuit 320 connected to the connection control module 200. The direct-conduction chopper circuit 310 includes an output switching transistor Q1 and an output circuit. The output circuit includes an output inductor L1 and an output diode D1. The boost circuit 320 includes a boost control switching transistor Q2, a boost capacitor C1, and a boost diode D3. The output switching transistor Q1 is a PMOS transistor, and the boost control switching transistor Q2 is an NMOS transistor.

[0129] When the atomization device operates in the direct-conduction chopper mode, it outputs in direct-conduction chopping. The MCU control module 200 outputs a PWM waveform to control the gate of the output switching transistor Q1 to output the required voltage. At this time, the boost function is turned off, that is, the MCU controls the gate of the boost control switching transistor Q2 to continuously output a high level, BST_PWM = 1, and the boost control switching transistor Q2 conducts. When boosting is required, the MCU controls the gate of the output switching transistor Q1 to continuously output a low level PWM = 0, the output switching transistor Q1 conducts, and the MCU control module 200 controls the gate of the boost control switching transistor Q2 to output a PWM waveform according to the boost requirement. The boost function is achieved when the boost control switching transistor Q2 is turned off.

[0130] In addition, as Figure 13 shown, the atomization device control method may further include: after system initialization and determining the working mode of the heating wire, obtaining the power level parameter. If the power level parameter is less than the preset power threshold Volt, controlling the atomization device to operate in the boost mode and outputting in pulse boosting. If the power level parameter is greater than or equal to the preset power threshold Volt, controlling the atomization device to operate in the direct-conduction chopper mode and outputting in direct-conduction chopping.
