[0054] The inventors of this application have discovered that in existing electronic atomizer devices, the amount of aerosol generated is virtually the same regardless of whether the user draws lightly or heavily. This is because, in existing passive liquid-feed atomizers, liquid permeates from the liquid-absorbing surface of the porous substrate to the atomizing surface via capillary action, making it impossible to control the liquid-feed rate and / or volume. In contrast, in existing active liquid-feed atomizers, the liquid-feed rate and / or volume of the micropump remain essentially constant.

[0055] 1 and 2 , FIG1 is a schematic structural diagram of an electronic atomization device provided in one embodiment of the present application, and FIG2 is a schematic structural diagram of an atomizer provided in one embodiment of the present application.

[0056] The control method of the atomizer 100 provided in this application is used for the power supply assembly 200 of the electronic atomization device 300, and the electronic atomization device 300 can be an active liquid supply type. The electronic atomization device 300 can be used to atomize an aerosol-generating matrix. The electronic atomization device 300 includes an atomizer 100 and a power supply assembly 200 that are electrically connected to each other; that is, the execution subject of the control method of the atomizer 100 of this application is the power supply assembly 200, and the object controlled by the power supply assembly 200 is the atomizer 100 of the electronic atomization device 300. Among them, the atomizer 100 is used to store the aerosol-generating matrix and atomize the aerosol-generating matrix to form an aerosol for the user to inhale. The atomizer 100 can be used in different fields, such as medical treatment, beauty, leisure smoking, etc. In a specific embodiment, the atomizer 100 can be used in an electronic aerosolization device to atomize the aerosol-generating matrix and generate an aerosol for the user to inhale. The following embodiments all take this leisure smoking as an example.

[0057] The atomizer 100 includes a housing 11, an atomizing core 12, a spray assembly 13, and a liquid storage bottle 14. The liquid storage bottle 14 includes a liquid storage chamber 141 for storing an aerosol-generating matrix. The spray assembly 13 is connected to the liquid storage bottle 14. The spray assembly 13 is used to spray the aerosol-generating matrix toward the atomizing core 12, so that the atomizing core 12 heats the aerosol-generating matrix to generate an aerosol. The housing 11 has an installation space, and the atomizing core 12 and the spray assembly 13 are accommodated in the installation space. The liquid storage bottle 14 can be accommodated in the installation space or be arranged outside the installation space. The specific setting is based on actual conditions.

[0058] The spray assembly 13 is used to spray an aerosol-generating matrix toward the atomizing core 12 to generate droplets. The atomizing core 12 is used to atomize the droplets to generate an aerosol. The atomized aerosol flows out of the atomizer 100 through the air outlet channel 17 and is ultimately inhaled by the user. The droplets in the aerosol are much smaller than the droplets sprayed by the spray assembly 13.

[0059] As shown in FIG2 , in this embodiment, the spray assembly 13 includes a micropump 131 and a nozzle 132. The micropump 131 and nozzle 132 are fluidically connected, providing a high-speed airflow to the nozzle 132 and creating a negative pressure within the nozzle 132. The nozzle 132 is fluidically connected to the liquid reservoir 14. Due to the negative pressure, the aerosol-generating substrate within the liquid reservoir 14 is transported to the nozzle 132. After being acted upon by the high-speed airflow provided by the micropump 131, the aerosol-generating substrate is sprayed from the nozzle 132 toward the atomizing core 12. Specifically, the nozzle 132 may include a main channel 1321, a tapered channel 1322, and a spray portion 1323. The liquid reservoir 14 may include a liquid storage chamber 141 and a liquid supply section 142. The liquid supply section 142 connects the liquid storage chamber 141 and the nozzle 132 to transport the aerosol-generating substrate within the liquid storage chamber 141 to the nozzle 132. In this embodiment, the liquid supply rate of the injection assembly 13 can be controlled by controlling the rotation speed of the micropump 131; the liquid supply volume of the injection assembly 13 can be controlled by controlling the rotation speed and rotation time of the micropump 131. It should be noted that the liquid supply rate of the injection assembly 13 is the mass of aerosol-forming substrate injected by the injection assembly 13 into the atomizing core 12 per unit time; and the liquid supply volume of the injection assembly 13 is the total mass of aerosol-forming substrate injected by the injection assembly 13 into the atomizing core 12 per user's puff. In other words, the atomization parameters of the nebulizer 100 during the atomization process can be controlled by controlling the rotation speed and rotation time of the micropump 131.

[0060] In another embodiment, the spray assembly 13 includes a spray head. The liquid storage bottle 14 is a high-pressure liquid storage tank. The aerosol-generating substrate in the liquid storage tank exists under high pressure. The spray head is connected to the high-pressure liquid storage tank through a pipe, and a switch is provided on the pipe. By controlling the switch, the aerosol-generating substrate in the high-pressure liquid storage tank can be sprayed through the spray head to the atomization core 12 to form droplets, and the droplets are heated by the atomization core 12 to generate an aerosol. In this embodiment, the structure of the spray head is similar to the spray head structure of a hairspray device. The spray rate of the spray assembly 13 can be controlled by controlling the opening degree of the spray head. That is, the mass of the aerosol-generating substrate sprayed by the spray assembly 13 to the atomization core 12 per unit time can be controlled by controlling the opening degree of the spray head. The liquid supply of the spray assembly 13 is controlled by controlling the opening degree and opening time of the spray head. That is, by simultaneously controlling the opening degree and opening time of the spray head, the total mass of the aerosol-generating substrate sprayed by the spray assembly 13 to the atomization core 12 per user's puff action is controlled, thereby controlling the atomization parameters during the atomization process of the atomizer 100 to meet different atomization requirements.

[0061] In this embodiment, the atomizing core 12 includes a heating element, which is used to heat and atomize the droplets sprayed by the spraying assembly 13 to generate aerosol. The heating element can be a heating plate or a heating net.

[0062] In one embodiment, when the heating body is a heating plate, and the directions in which the heating plate and the spraying assembly 13 spray the aerosol-generating matrix are perpendicular to each other, a gap is left between at least one side of the heating plate and the inner wall surface of the installation space. The aerosol generated by the heating plate heating and atomizing the aerosol-generating matrix is ​​transmitted to the air outlet channel 17 through the gap between the heating plate and the inner wall surface of the installation space for the user to inhale.

[0063] In one embodiment, when the heating element is a heating net, and the heating net and the direction in which the aerosol-generating substrate is ejected from the ejection assembly 13 are perpendicular to each other, at least one side of the heating net is fixedly connected to the inner wall of the installation space. In this embodiment, the periphery of the heating net is fixedly connected to the inner wall of the installation space. The aerosol generated by the heating net heating the aerosol-generating substrate ejected from the ejection assembly 13 can be directly transmitted through the heating net to the air outlet channel 17 for inhalation by the user.

[0064] In one embodiment, the heating element is a heating plate, and the heating plate is parallel to the direction in which the aerosol-generating substrate is ejected from the ejection assembly 13. In other words, the heating plate is positioned to the side of the region in which the aerosol-generating substrate is ejected from the ejection assembly 13, and the heating plate heats and atomizes droplets of the aerosol-generating substrate to generate an aerosol.

[0065] In this embodiment, the angle θ between the heating net or heating plate and the direction of spraying the aerosol generating substrate may be in the range of 0°≤θ≤90°. The specific setting method and setting angle may be set according to actual conditions.

[0066] Please refer to FIG3 , which is a module diagram of an electronic atomization device provided in one embodiment of the present application.

[0067] 1 and 3 , the power supply assembly 200 is coupled to the atomizer 100 of the active liquid-supply electronic atomization device 300 to control the operation of the atomizer 100. The power supply assembly 200 includes a processor 210, a memory 220, a battery 230, a controller 240, and an airflow sensor 250. The memory 220 stores program instructions.

[0068] Specifically, the processor 210 is used to control the operation of the power supply assembly 200. The processor 210 can also be called a CPU (Central Processing Unit). The processor 210 is electrically connected to the controller 240 so that the controller 240 can control the different components in the power supply assembly 200. Specifically, the controller 240 can include an injection assembly control unit 241, a voltage control unit 242, and a heating control unit 243, wherein the voltage control unit 242 can be electrically connected to the processor 210 and the battery 230, and the voltage control unit 242 controls the battery 230 to start or stop supplying power, as well as control the output voltage of the battery 230. The injection assembly control unit 241 can be electrically connected to the voltage control unit 242 and the injection assembly 13, so that the injection assembly control unit 241, under the drive of the voltage control unit 242, further controls the injection assembly 13 to start or stop running, and controls the micropump 131 in the injection assembly 13 to run at different speeds, such as the first speed, the second speed or the third speed; or controls the opening degree of the nozzle in the injection assembly 13 to control the liquid supply rate and / or liquid supply amount of the injection assembly 13. The heating control unit 243 can be electrically connected to the processor 210, and the heating control unit 243 controls the atomization core 12 to heat and operate at different powers. For example, the atomization core 12 includes a heating element, and the heating control unit 243 controls the heating element to preheat at a first power and heat and atomize the aerosol-generating matrix at a second power for the user to inhale. Optionally, the injection assembly control unit 241, the voltage control unit 242 and the heating control unit 243 can be a microcontroller 240, etc., and this application is not limited to this.

[0069] In one embodiment, the processor 210 may be an integrated circuit chip having signal processing capabilities. The processor 210 may also be a general-purpose processor 210, a digital signal processor 210 (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component. The general-purpose processor 210 may be a microprocessor 210 or any conventional processor 210.

[0070] The memory 220 is electrically connected to the processor 210 and is used to store computer programs. The memory 220 can be RAM, ROM, or other types of storage devices. Specifically, the memory 220 may include one or more computer-readable storage media 400, which may be non-transitory. The memory 220 may also include a high-speed random access memory 220 and a non-volatile memory 220, such as one or more disk storage devices or flash memory storage devices. In some embodiments, the non-transitory computer-readable storage medium 400 in the memory 220 is used to store at least one program code.

[0071] The processor 210 retrieves computer program instructions from the memory 220 to execute the computer program stored in the memory 220 to implement the control method of the atomizer 100 in the embodiment of the present application.

[0072] The airflow sensor 250 is electrically connected to the processor 210. The airflow sensor 250 is used to monitor the negative pressure when the user takes a puff, that is, the negative pressure. The negative pressure monitored by the airflow sensor 250 can be transmitted to the processor 210. The processor 210 judges and analyzes the user's puffing parameters and other puffing habits based on the negative pressure monitored by the airflow sensor 250, and then controls the operation of the atomizer 100 through the injection assembly control unit 241, the voltage control unit 242, and the heating control unit 243. The airflow sensor 250 can be a microphone.

[0073] The battery 230 is used to provide electrical energy for the operation of the atomizer 100, enabling the atomizer 100 to atomize the aerosol-generating substrate to form an aerosol. The controller 240 is used to control the operation of the atomizer 100. The power supply assembly 200 may also include other components such as a battery holder (not shown) and a control circuit board (not shown).

[0074] The atomizer 100 and the power supply assembly 200 of the present application may be detachably connected or may be an integral, non-detachable structure. For example, the atomizer 100 and the power supply assembly 200 may share a housing 11 , and the present application does not impose any restrictions on this.

[0075] Referring to Figures 4 to 8, Figure 4 is a flow chart of the control method of the nebulizer provided by the present application, Figure 5 is a flow chart of step S1 in one embodiment of the control method of the nebulizer provided by the present application, Figure 6 is a schematic diagram of the negative pressure-time curve in one embodiment of the control method of the nebulizer provided by the present application, Figure 7 is a flow chart of step S2 in one embodiment of the control method of the nebulizer provided by the present application, and Figure 8 is a flow chart of step S2 in another embodiment of the control method of the nebulizer provided by the present application.

[0076] This application provides a control method for an atomizer 100, which is used for the power supply assembly 200 of an active liquid supply type electronic atomization device 300, so that the electronic atomization device 300 can achieve adaptive control for different user groups. As shown in FIG4 , the control method for the atomizer 100 includes:

[0077] S1: Obtain the user's puff parameters each time.

[0078] Specifically, the puff parameters include negative suction pressure and / or puff time. The negative suction pressure is the negative suction pressure generated when the user takes a puff, and the puff time is the total puff duration of each puff performed by the user. The airflow sensor 250 monitors the negative suction pressure generated when the user takes a puff and the duration of each puff. The processor 210 obtains the negative suction pressure and / or puff time of each puff from the airflow sensor 250 to facilitate control of the subsequent atomization process. The step of obtaining the user's puff parameters each time can be performed within a certain time period of a puff, or can be performed throughout the entire puff process.

[0079] In one embodiment, the step of obtaining the user's puff parameters for each time in step S1 includes:

[0080] During the first preset time when the user starts to puff, the user's puff pressure is obtained every N seconds, and the maximum puff pressure is used as the puff negative pressure, and the puff negative pressure is used as the puff parameter.

[0081] Specifically, the user's inhalation pressure needs to be acquired at least twice within the first preset time. Optionally, the first preset time is less than 0.5 seconds, and N is less than or equal to 0.2, meaning that within the 0.5-second period, the user's inhalation pressure is acquired at least once every 0.2 seconds. Preferably, N is less than or equal to 0.1, meaning that the user's inhalation pressure is acquired at least once every 0.1 seconds. In other words, within the first preset time, the airflow sensor 250 monitors the user's inhalation pressure every N seconds and transmits the monitored user's inhalation pressure to the processor 210.

[0082] In one embodiment, the maximum suction pressure obtained within a first preset time period can be used as the negative suction pressure, and the negative suction pressure can be used as the suction parameter. During this time period, the user's negative suction pressure can be determined and the user's puffing habits analyzed. Specifically, the maximum suction pressure obtained within the first preset time period, i.e., the negative suction pressure, can be compared with a preset suction parameter range corresponding to the control mode to determine whether the suction parameter meets the preset suction parameter range corresponding to the control mode. If so, the control mode is directly entered, and the atomizer 100 operates in the control mode during the atomization process. In other embodiments, all suction pressures obtained within the first preset time period can be used as the negative suction pressure, and all suction pressures can be used as the suction parameters. That is, in this embodiment, the suction parameters only include the negative suction pressure. It can be understood that compared to using all suction pressures obtained within the first preset time period as the negative suction pressure, using only the maximum suction pressure as the negative suction pressure and using the negative suction pressure as the suction parameter, the method and steps for determining whether the suction parameter meets the preset suction parameter range of the control mode are simpler and more efficient.

[0083] Optionally, the user's suction pressure can be obtained every N seconds within the first preset time of each user's suction action, and the maximum suction pressure within the first preset time is used as the suction negative pressure to determine whether the suction parameters of each suction action meet the preset suction parameter range of the control mode. If the suction parameters of a certain time do not meet the preset suction parameter range, the control mode is exited directly.

[0084] It can be understood that in this method, the suction negative pressure obtained within the first preset time of each puffing action of the user is used as a parameter for judging the user's puffing habits. After the first preset time of each puffing action of the user, the selected control mode can be entered to meet the user's puffing habits.

[0085] In another embodiment, as shown in FIG5 , the step of obtaining the user's puff parameters each time in step S1 includes:

[0086] S11: Obtain the user's suction negative pressure every N seconds.

[0087] Specifically, the airflow sensor 250 monitors the user's inhalation negative pressure every N seconds and transmits the monitored user's inhalation negative pressure to the processor 210. Wherein, N is less than or equal to 0.1, that is, the user's inhalation negative pressure is obtained at least once every 0.1 seconds.

[0088] S12: Record the total puffing time of each puff by the user as the puffing time; and use the puffing negative pressure and the puffing time as the puffing parameters.

[0089] Specifically, the puff time corresponding to each puff taken by the user, i.e., the total puff duration, is monitored and recorded. The total duration of each puff taken by the user is used as the puff time. The puff time and the negative pressure obtained in step S11 are then used as puff parameters. In this embodiment, the puff parameters include the puff time and negative pressure. The total puff time for each puff taken by the user can be defined as the duration during which the puff airflow generated by each puff taken by the user, as detected by the airflow sensor 250, meets a certain threshold. This serves as the puff time. By obtaining the user's negative pressure every N seconds and recording the total puff duration for each puff, the user's puff parameters are obtained for each puff, facilitating subsequent judgment during the atomization process. It will be appreciated that this method, by considering all negative pressures and the total puff duration throughout the entire puffing process, allows for more accurate judgment of the user's puffing habits. However, these parameters are only obtained after the user has completed at least one puff. Therefore, the selected control mode cannot be entered until the user has completed at least one puff, i.e., the next puff.

[0090] Specifically, in step S11, the user's negative pressure when inhaling may be obtained every N seconds within a first preset time period after the user begins to inhale, or the user's negative pressure when inhaling may be obtained every N seconds throughout the entire process of the user's inhalation. It will be appreciated that if the user's negative pressure when inhaling is obtained every N seconds within the first preset time period after the user begins to inhale as the inhalation parameter, the determination step can be simplified.

[0091] S2: Control the atomization parameters of the atomizer according to the suction parameters.

[0092] Specifically, the atomization parameters of the nebulizer 100 include any one or more of the liquid supply rate of the injection component 13, the liquid supply amount of the injection component 13, and the atomization power of the atomizer core 12. The liquid supply rate of the injection component 13 is the mass of the aerosol-generating matrix injected by the injection component 13 to the atomizer core 12 per unit time; the liquid supply amount of the injection component 13 is the total mass of the aerosol-generating matrix injected by the injection component 13 to the atomizer core 12 each time the user draws a puff. In other words, the processor 210 controls the mass of the aerosol-generating matrix injected by the injection component 13 to the atomizer core 12 per unit time, and / or controls the total mass of the aerosol-generating matrix injected by the injection component 13 to the atomizer core 12 each time the user draws a puff, based on the obtained suction parameters of the suction negative pressure and / or the puff time of each puff action of the user. It can be understood that the atomization parameters of the atomizer 100 can be controlled by controlling one of the liquid supply rate of the injection assembly 13, the liquid supply amount of the injection assembly 13, and the atomization power of the atomization core 12, or the liquid supply rate of the injection assembly 13, the liquid supply amount of the injection assembly 13, and the atomization power of the atomization core 12 can be controlled at the same time to meet the user's atomization needs under different puffing parameters.

[0093] Furthermore, the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters in the above step S2 specifically includes:

[0094] The liquid supply rate and / or liquid supply amount of the spray assembly is controlled according to the suction parameters, and the atomization power of the atomization core is controlled.

[0095] Specifically, the atomization parameters include not only the liquid supply rate and / or liquid supply volume of the injection assembly 13, but also the atomization power of the atomization core 12. The processor 210 controls not only the liquid supply rate and / or liquid supply volume of the injection assembly 13, but also the atomization power of the atomization core 12 based on the suction parameters of the suction negative pressure and / or the suction time of each puff action of the user obtained. In one embodiment, the atomization core 12 includes a heating element, which is used to heat the atomized aerosol generating matrix to generate an aerosol. The heating element can be any structure such as a heating plate, a heating net, or a heating film. The atomization power of the atomization core 12 is the heating power of the heating element. The heating power of the heating element is controlled by the heating control unit 243 of the controller 240 so that the heating power of the heating element matches the liquid supply rate of the injection assembly 13 to meet the actual puffing needs of the user, so that the atomizer 100 can better perform atomization and improve the atomization taste of the atomizer 100.

[0096] For example, if the suction negative pressure in the user's suction parameters obtained is relatively large, the liquid supply rate of the injection assembly 13 and the heating power of the heating element can be controlled to be relatively large values, so that the atomization efficiency of the nebulizer 100 is relatively high, and the amount of aerosol generated by heating and atomization per unit time is relatively large, thereby avoiding insufficient aerosol generated by atomization and failure to meet the user's suction needs; if the suction negative pressure in the user's suction parameters obtained is relatively small, the liquid supply rate of the injection assembly 13 and the heating power of the heating element can be controlled to be relatively small values, so that the atomization efficiency of the nebulizer 100 is within an appropriate range, and the amount of aerosol generated by heating and atomization per unit time does not need to be too much, and can meet the user's needs, thereby avoiding excessive atomization efficiency when the heating power is too large, excessive amount of aerosol generated, and waste caused by the user not being able to inhale in time.

[0097] Furthermore, the duration of liquid delivery by the spray assembly 13, i.e., the amount of liquid delivered by the spray assembly 13, can be controlled based on the duration of the puff, thereby satisfying the needs of users with different puffing habits. For example, if the user puffs for 5 seconds each time, the spray assembly 13 will automatically stop after detecting the start of the puff.

[0098] In one embodiment, the injection assembly 13 includes a micropump 131 and a nozzle 132. The micropump 131 and the nozzle 132 are gas-connected. The micropump 131 is used to provide a high-speed airflow to the nozzle 132. The aerosol-generating matrix in the liquid storage bottle 14 is transferred to the position of the nozzle 132 and is then sprayed by the nozzle 132 to the heating element for heating and atomization. The rotation speed of the micropump 131 determines the liquid supply rate of the injection assembly 13 to the atomization core 12. The faster the rotation speed of the micropump 131, the faster the liquid supply rate of the injection assembly 13 to the atomization core 12, that is, the greater the mass of the aerosol-generating matrix sprayed by the injection assembly 13 to the atomization core 12 per unit time. The liquid supply rate of the injection assembly 13 can be controlled by controlling the rotation speed of the micropump 131. At the same time, the rotation speed and rotation time of the micropump 131 jointly determine the liquid supply of the injection assembly 13, that is, the total mass of the aerosol-generating matrix injected by the injection assembly 13 into the atomizing core 12 each time the user draws in air. The liquid supply of the injection assembly 13 can be controlled by simultaneously controlling the rotation speed and rotation time of the micropump 131.

[0099] In another embodiment, the spray assembly 13 includes a spray head, which is similar to the spray head structure of a hair spray device. The liquid storage bottle 14 is a high-pressure liquid storage tank. The aerosol-generating substrate in the liquid storage tank is present under high pressure. The spray head is connected to the high-pressure liquid storage tank via a pipe. The pipe is provided with a switch. By controlling the switch, the aerosol-generating substrate in the high-pressure liquid storage tank can be sprayed through the spray head toward the atomization core 12 to form droplets. The droplets are heated by the atomization core 12 to generate an aerosol. The opening degree of the spray head can be adjusted and controlled. The opening degree of the spray head can be controlled according to the user's puff parameters to control the liquid supply rate of the spray assembly 13. For example, the greater the opening degree of the spray head, the greater the mass of the aerosol-generating substrate sprayed by the spray assembly 13 to the atomization core 12 per unit time. The liquid supply of the spray assembly 13 can be controlled by simultaneously controlling the opening degree and opening time of the spray head. For example, the smaller the opening degree of the spray head and the shorter the opening time of the spray head, the smaller the total mass of the aerosol-generating substrate sprayed by the spray assembly 13 to the atomization core 12 per puff by the user.

[0100] It can be understood that by controlling the rotation speed of the micropump 131 and / or the rotation speed and rotation time of the micropump 131 according to the user's suction parameters obtained, or by controlling the opening degree and / or the opening degree and opening time of the nozzle according to the user's suction parameters obtained, and then controlling the liquid supply rate and / or liquid supply amount of the injection component 13, the mass of the aerosol generating matrix injected by the injection component 13 into the atomization core 12 per unit time and / or the total mass of the aerosol generating matrix injected by the injection component 13 into the atomization core 12 each time the user draws a puff can reach the value actually required by the user, thereby meeting the user's actual suction needs.

[0101] Furthermore, the atomizer 100 stores at least one control mode, which includes a preset correspondence between a puff parameter range and atomization parameters, i.e., a one-to-one correspondence between the puff parameter range and the atomization parameters. The step of controlling the atomization parameters of the atomizer according to the puff parameter in step S2 above includes:

[0102] In response to a puff parameter during puffing satisfying a puff parameter range of one of the control modes for more than a first preset number of times, the control mode is entered.

[0103] Specifically, the puff parameters include the suction negative pressure and the total puff duration per puff by the user, i.e., the puff time. The nebulizer 100 stores at least one control mode, each of which includes its corresponding puff parameter range and atomization parameters. Based on the puff parameters of the user obtained multiple times, the puff parameters of the multiple user puff actions are compared with the puff parameter range of the control mode. If the puff parameters of the multiple puff actions meet the puff parameter range of one of the control modes more than a first preset number of times, the nebulizer 100 enters the control mode and controls the nebulizer 100 to perform atomization according to the atomization parameters corresponding to the puff parameter range of the control mode.

[0104] It can be understood that the suction parameters of multiple puffs satisfy the suction parameter range of one of the control modes for more than a first preset number of times, and the suction parameters of multiple consecutive puffs are all within the suction parameter range of the control mode and the consecutive number of times exceeds the first preset number. For example, the first preset number is five times, and the suction parameters of six consecutive puffs are all within the suction parameter range of one of the control modes, that is, it is determined that the suction parameters of multiple puffs satisfy the suction parameter range of the control mode for more than the first preset number, and the control mode is entered; or, the suction parameters of multiple puffs exceeding the first preset number satisfy the suction parameter range of one of the control modes, for example, the first preset number is seven times, and the suction parameters of more than seven out of ten puffs satisfy the suction parameter range of one of the control modes, that is, it is determined that the suction parameters of multiple puffs satisfy the suction parameter range of the control mode for more than the first preset number, and the control mode is entered; it can be designed according to specific needs, and the first preset number can also be preset based on experience.

[0105] Specifically, a puff curve can be formed by fitting or selecting. For example, there is a certain correspondence between the puff parameter range and the atomization parameter, with different puff parameter ranges corresponding to different atomization parameters. Based on the puff parameters of multiple monitored puffs, when the number of times the puff parameters of the multiple puffs meet the puff parameter range of a certain control mode exceeds a first preset number, the atomization parameter corresponding to the puff parameter range of the control mode is calculated based on the correspondence between the puff parameter range and the atomization parameter, i.e., the corresponding atomization parameter is calculated using a formula method, thereby fitting to form a puff curve. Alternatively, the atomizer 100 may pre-store multiple preset correspondence curves between puff parameter ranges and atomization parameters, and the corresponding relationship curve, i.e., the puff curve, can be directly selected based on the puff parameter range of the control mode. It will be appreciated that, since the processor 210 of the electronic atomization device 300 generally has limited computing power, pre-storing multiple preset correspondence curves between puff parameter ranges and atomization parameters and selecting the matching curve based on the puff parameter range in actual use simplifies the calculations of the processor 210 and improves processing efficiency. The corresponding relationship curves of multiple preset suction parameter ranges and atomization parameters can be formed in advance through multiple experiments and computer fitting.

[0106] In response to the puff parameters of multiple puffs satisfying the puff parameter range of one of the control modes for more than a first preset number of times, the processor 210 enters the control mode and controls the nebulizer 100 to perform atomization according to the corresponding atomization parameters based on the correspondence between the puff parameter range and the atomization parameters included in the control mode. The correspondence between the puff parameter range and the atomization parameters can be a table or a curve.

[0107] In this application, the atomizer 100 stores at least one control mode, and each control mode includes the corresponding relationship between the preset suction parameter range and the atomization parameters. In one embodiment, the suction parameters include two parameters, namely the suction negative pressure and the suction time. The suction negative pressure includes two preset intensity thresholds Pa and Pb, and the suction time includes a preset time threshold Ta. The suction negative pressure is divided into three preset intensity threshold ranges according to the two preset intensity thresholds Pa and Pb, namely the first preset intensity threshold range P < Pa, the second preset intensity threshold range Pa ≤ P < Pb, and the third preset intensity threshold range P ≥ Pb; the suction time is divided into two preset time threshold ranges according to the preset time threshold Ta, namely the first preset time threshold range T < Ta and the second preset time threshold range T ≥ Ta. The atomizer 100 includes six control modes, namely the first control mode L1, the second control mode L2,..., the sixth control mode L6. As shown in the following table, the suction parameter range of the first control mode L1 is that the suction negative pressure is in the first preset intensity threshold range and the suction time is in the first preset time threshold range, that is, the suction parameter range of the first control mode L1 is P < Pa, T < Ta; the suction parameter range of the second control mode L2 is that the suction negative pressure is in the first preset intensity threshold range and the suction time is in the second preset time threshold range, that is, the suction parameter range of the second control mode L2 is P < Pa, T ≥ Ta; the suction parameter range of the third control mode L3 is that the suction negative pressure is in the second preset intensity threshold range and the suction time is in the first preset time threshold range, that is, the suction parameter range of the third control mode L3 is Pa ≤ P < Pb, T < Ta;... The suction parameter ranges of other control modes can be deduced by analogy and will not be elaborated here.

[0108] Each control mode's suction parameter range has corresponding atomization parameters. The atomization parameters include the liquid supply rate of the injection component 13, the liquid supply amount of the injection component 13, and the atomization power of the atomization core 12. As shown in the following table, the atomization parameters corresponding to the first control mode L1 are the first atomization parameters. The first atomization parameters include the first liquid supply rate V1, the first liquid supply amount M1, and the first atomization power W1. In the first control mode L1, the atomizer 100 is controlled to work at the first liquid supply rate V1, the first liquid supply amount M1, and the first atomization power W1,... In the sixth control mode L6, the atomizer 100 is controlled to work at the sixth liquid supply rate V6, the sixth liquid supply amount M6, and the sixth atomization power W6.

[0109] The aspiration parameters obtained from multiple aspirations of the user can be compared with the aspiration parameter ranges of the above six control modes to analyze and determine the user's aspiration habits, and then enter the corresponding control mode to control the operation of the atomizer 100. For example, the first preset number is five. If the number of times that the aspiration parameters obtained from the multiple aspirations of the user satisfy the range of aspiration negative pressure Pa ≤ P < Pb and the range of aspiration time T < Ta exceeds five times, the atomizer 100 enters the third control mode L3, and controls the atomizer 100 to atomize with the third atomization parameters, that is, the third liquid supply rate V3, the third liquid supply amount M3, and the third atomization power W3.

[0110] It can be understood that in other embodiments, the number of control modes of the atomizer 100 can also be set to other numbers. For example, the atomizer 100 can store two, three, four, or five control modes, and the aspiration parameter ranges of each control mode are different. The aspiration parameters obtained from multiple aspirations of the user are compared with the aspiration parameter ranges preset by multiple control modes. If the number of times that the aspiration parameters of multiple aspirations satisfy the aspiration parameter range of a certain control mode among the multiple control modes exceeds the first preset number, then enter this control mode, and control the atomizer 100 to operate with the atomization parameters of this control mode.

[0111] Furthermore, the step of controlling the atomization parameters of the atomizer 100 according to the aspiration parameters in the above step S2 further includes:

[0112] In response to the aspiration parameters during aspiration not satisfying the aspiration parameter range of the control mode exceeding the second preset number of times, exit the control mode. [[ID=1X]]

[0113] Specifically, after entering the control mode, the airflow sensor 250 still monitors the user's aspiration actions to monitor aspiration parameters such as the aspiration negative pressure and aspiration time of each user aspiration, and the processor 210 obtains the aspiration parameters of each user aspiration monitored by the airflow sensor 250.

[0114] Compare the aspiration parameters obtained from multiple aspirations of the user with the aspiration parameter range of the control mode in which it is located. When the aspiration parameters of multiple aspirations do not satisfy the aspiration parameter range of this control mode exceeding the second preset number of times, the atomizer 100 exits this control mode, that is, when the number of times that the aspiration parameters obtained from multiple aspirations of the user are not within the aspiration parameter range of this control mode exceeds the second preset number of times, exit this control mode.

[0115] The puffing parameters of multiple puffs do not satisfy the puffing parameter range of the control mode for more than a second preset number of times. The puffing parameters of multiple consecutive puffs are all outside the puffing parameter range of the control mode and the consecutive number of times exceeds the second preset number. For example, the second preset number of times is two, and the puffing parameters of three consecutive puffs are all outside the puffing parameter range of the control mode, that is, it is determined that the puffing parameters of multiple puffs do not satisfy the puffing parameter range of the control mode for more than the second preset number, and the control mode is exited. Alternatively, the puffing parameters within the multiple puff range do not satisfy the puffing parameter range of the control mode for more than the second preset number of times. For example, the second preset number of times is three, and the puffing parameters of ten puffs do not satisfy the puffing parameter range of the control mode for more than three times, that is, it is determined that the puffing parameters of multiple puffs do not satisfy the puffing parameter range of the control mode for more than the second preset number, and the control mode is exited. The design can be based on specific needs, and the second preset number can also be preset based on experience.

[0116] In one embodiment, the step of controlling the atomization parameters of the atomizer 100 according to the puffing parameters in step S2 includes:

[0117] S21: During the rising negative pressure phase of the user's inhalation, in response to the difference ΔP of the user's inhalation negative pressure rising within the second preset time being greater than the first negative pressure threshold Ps, the nebulizer is controlled to stop atomizing.

[0118] Specifically, during the entire process of a user's puffing action, the suction negative pressure is obtained at regular intervals. During the rising phase of the user's suction negative pressure, that is, the phase where the subsequent suction negative pressure is greater than the previous suction negative pressure, when the difference ΔP of the user's suction negative pressure rise within the second preset time is greater than the first negative pressure threshold Ps, the atomizer 100 is directly controlled to stop the atomization operation. That is, as long as the user's suction negative pressure is in the rising phase during the user's puffing action, and the difference ΔP of the user's suction negative pressure rise is greater than the first negative pressure threshold Ps within any second preset time, it can be determined that the user has stopped the puffing action, and the atomizer 100 is directly controlled to stop the atomization operation in advance, which is beneficial to energy saving. Among them, the controller 240 controls the atomizer 100 to stop atomization, the injection assembly control unit 241 of the controller 240 controls the injection assembly 13 to stop supplying liquid to the atomizer core 12, and the heating control unit 243 of the controller 240 controls the atomizer core 12 to stop heating the atomization process in advance, which is beneficial to energy saving. For example, the second preset time is 0.3 seconds, the first negative pressure threshold Ps is 800 Pa, and during the user's suction negative pressure rising stage, if the difference ΔP of the suction negative pressure rise in any 0.3 second time period is greater than 800 Pa, the nebulizer 100 is controlled to stop atomizing at the last time point of the 0.3 second.

[0119] Referring to Figure 6, in one embodiment, the airflow sensor 250 monitors the user's suction negative pressure every 0.1 seconds, and the processor 210 obtains the suction negative pressure monitored at multiple time points from the airflow sensor 250, and fits the suction negative pressure and the corresponding time points to obtain the negative pressure-time curve shown in Figure 6. Each time the user takes a puff, the suction negative pressure basically shows a state of first decreasing and then rising. In the prior art, when the user takes a puff, the suction negative pressure at which the user stops taking a puff is set to a fixed negative pressure threshold, and whether the user stops taking a puff is determined based on the stop suction negative pressure threshold. When the user's suction negative pressure reaches the stop suction negative pressure threshold, it indicates that the user has stopped taking a puff, and then the nebulizer is controlled to stop atomizing. For example, as shown in FIG6 , the starting negative pressure of the nebulizer 100 is -300 Pa, and the negative pressure threshold for stopping suction is also -300 Pa. The nebulizer 100 can be controlled to stop atomizing only when the user's suction negative pressure reaches -300 Pa again, that is, atomization can be stopped at the nineteenth time point D3 in FIG8 .

[0120] In the control method of the nebulizer 100 provided in this embodiment, when the difference ΔP of the user's suction negative pressure rise during the second preset time is greater than the first negative pressure threshold Ps, that is, the difference ΔP of the suction negative pressure corresponding to the last time point and the first time point of the second preset time is greater than the first negative pressure threshold Ps, the nebulizer 100 is controlled to stop atomizing. As shown in Figure 6, during the user's suction negative pressure rising stage, the second preset time is 0.1 seconds. Within 0.1 seconds, the difference ΔP of the suction negative pressure rise at the seventeenth time point D2 and the sixteenth time point D1 is greater than the first negative pressure threshold Ps, then the nebulizer 100 is immediately controlled to stop atomizing at the last time point of the second preset time, that is, the seventeenth time point D2. As can be seen from Figure 6, using the control method of the nebulizer 100 provided by the present application to control the nebulizer 100, the time point at which the nebulizer 100 stops atomizing is earlier than the time point at which the nebulizer stops atomizing in the prior art, and the nebulizer 100 can be controlled to stop atomizing in advance, saving energy.

[0121] While the negative pressure-time curve is typically the same for the same user, it is typically different for different users. Compared to the prior art method of determining whether a user has stopped puffing based on a negative pressure threshold for stopping puffing, the present invention uses the relationship between the difference ΔP between the user's puff negative pressure rise during a second preset time and the first negative pressure threshold Ps to determine whether a user has stopped puffing. This method is more intelligent and more adaptable to different user groups, enabling adaptive control for different user groups and improving the performance of the atomizer 100.

[0122] 7 , in one embodiment, the step of controlling the atomization parameters of the atomizer 100 according to the puffing parameters in step S2 includes the following steps after step S21:

[0123] S22: Record the user's suction negative pressure corresponding to the last time point of the second preset time as the second negative pressure threshold.

[0124] Specifically, based on the last time point of the second preset period when the difference ΔP in the user's suction negative pressure increase in step S21 exceeds the first negative pressure threshold Ps, the suction negative pressure corresponding to that time point is recorded as the second negative pressure threshold. As shown in FIG6 , the suction negative pressure corresponding to the seventeenth time point D2, the last time point of the second preset period (e.g., negative 1100 Pa), is recorded as the second negative pressure threshold.

[0125] S23: In response to the subsequent user's inhalation negative pressure being greater than the second negative pressure threshold, the nebulizer is controlled to stop atomizing.

[0126] Specifically, during the subsequent user's puffing action, the size of the user's puffing negative pressure and the second negative pressure threshold is judged based on the puffing negative pressure obtained at regular intervals. When the user's puffing negative pressure is greater than the second negative pressure threshold, it indicates that the user has stopped puffing, and the controller 240 immediately controls the nebulizer 100 to stop atomizing, which is conducive to saving energy.

[0127] It can be understood that in this embodiment, the user's puffing negative pressure corresponding to the last time point of the second preset time is used as the second negative pressure threshold, and the second negative pressure threshold is directly used as the basis for judging whether the user has stopped the puffing action, and then judging when the nebulizer stops atomizing. Compared with each puffing action, whether the difference △P of the user's puffing negative pressure increase within the above-mentioned second preset time is greater than the first negative pressure threshold Ps to judge whether the user has stopped the puffing action, the judgment process is simpler and more efficient.

[0128] In another embodiment, the step of obtaining the user's puff parameters each time in step S1 includes:

[0129] The user's suction negative pressure is obtained once at regular intervals.

[0130] Specifically, when the user performs a puff, the airflow sensor 250 monitors the user's negative suction pressure at regular intervals throughout the entire puff process. The airflow sensor 250 monitors the user's negative suction pressure multiple times throughout the entire puff process, that is, monitors the user's negative suction pressure at multiple time points. The processor 210 obtains the negative suction pressures monitored at multiple time points from the airflow sensor 250. For example, the user's negative suction pressure may be monitored every 0.1 second throughout the entire puff process. The processor 210 obtains the negative suction pressures monitored at multiple time points every 0.1 second throughout the entire puff process.

[0131] 8 , the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters in step S2 includes:

[0132] S21b: Generate a negative pressure-time curve according to the suction negative pressure and the corresponding time points.

[0133] Specifically, based on the suction negative pressure monitored at regular intervals during the entire process of a user's puffing action, the suction negative pressure at multiple time points during the entire process of a user's puffing action is obtained. Based on the obtained suction negative pressures at multiple corresponding time points, a negative pressure-time curve is fitted and generated. The vertical axis of the negative pressure-time curve represents the suction negative pressure, and the horizontal axis represents the corresponding time point.

[0134] S22b: Obtain the slope of the negative pressure-time curve.

[0135] Specifically, according to the negative pressure-time curve generated by the above fitting, the slope between each two adjacent points on the curve is obtained.

[0136] S23b: In response to the slope being greater than the slope threshold, controlling the atomizer to stop atomization.

[0137] Specifically, based on the slope of the obtained curve, the size of the obtained slope and the slope threshold is judged. When the obtained slope is greater than the slope threshold, the controller 240 controls the nebulizer 100 to stop the atomization work. In a specific embodiment, the nebulizer 100 can be controlled to stop the atomization work when the slope between two adjacent points in the negative pressure-time curve is greater than the slope threshold; or the nebulizer 100 can be controlled to stop the atomization work when the slope of four consecutive time points in the entire negative pressure-time curve, that is, the slope of three consecutive time periods is greater than the slope threshold, so as to avoid misjudging a sudden change in slope caused by the user's ventilation or coughing as stopping the suction. Among them, the injection component control unit 241 of the controller 240 controls the injection component 13 to stop supplying liquid to the atomization core 12, and the heating control unit 243 of the controller 240 controls the atomization core 12 to stop heating the atomization process, which is conducive to saving energy. The fact that the slope of the negative pressure-time curve in this embodiment is greater than the slope threshold has the same meaning as the fact that the difference ΔP in the increase in the negative suction pressure within the second preset time is greater than the first negative pressure threshold Ps in the above embodiment, both indicating a sudden change in the negative suction pressure of the user.

[0138] It is understandable that even the same user may use different puffing methods, that is, have different negative pressure-time curves. Therefore, using the slope to determine whether the user has stopped puffing is more accurate than setting the second negative pressure threshold as described above.

[0139] Please refer to FIG9 , which is a schematic diagram of the structure of a computer-readable storage medium provided in one embodiment of the present application.

[0140] The present application also provides a computer-readable storage medium 400 , which stores a program file 401 . The program file 401 can be executed to implement the control method of the atomizer 100 as described above.

[0141] Specifically, if the processor 210, memory 220 and other units integrated in the power supply assembly 200 are implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium 400. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, or all or part of the technical solution can be embodied in the form of a software product. The computer software product is stored in a storage medium 400, including several instructions / computer programs for enabling a computer device (which can be a personal computer, server, or network device, etc.) or a processor 210 (processor) to perform all or part of the steps of the methods of various embodiments of the present invention. The storage medium 400 includes various media such as a USB flash drive, a mobile hard disk, a read-only memory 220 (ROM), a random access memory 220 (RAM), a magnetic disk or an optical disk, as well as electronic devices such as computers, mobile phones, laptops, tablets, cameras, etc. having the above-mentioned storage medium 400.

[0142] The description of the execution process of the program file 401 in the computer-readable storage medium 400 can refer to the description in the embodiment of the control method of the atomizer 100 of the present application, and will not be repeated here.

[0143] Different from the prior art, the present application discloses a control method for an electronic atomization device 300, a power supply assembly 200, an atomizer 100, and a storage medium 400. The control method of the atomizer 100 is used for the power supply assembly 200 of the active liquid supply electronic atomization device 300.
