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

Specifically, the suction parameters include suction negative pressure and/or suction time. The suction negative pressure is the suction negative pressure generated when the user performs a suction action. The suction time is the total suction each time the user performs a suction action. The suction duration is monitored through the airflow sensor 250, and the suction negative pressure generated each time the user performs a suction action and the time of each suction are monitored.

The step of obtaining the user's puff parameters each time can be performed within a certain time period of one puff, or during the entire process of one puff.

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

During the first preset time when the user starts suctioning, the user's suction pressure is obtained every N seconds, the maximum suction pressure is used as the suction negative pressure, and the suction negative pressure is used as the suction parameter.

Specifically, the user's suction pressure needs to be obtained 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, that is, within 0.5 seconds, the user's suction pressure is obtained at least every 0.2 seconds. Preferably, N is less than or equal to 0.1, that is, the user's suction pressure is obtained at least every 0.1 seconds. That is to say, within the first preset time, the airflow sensor 250 monitors the user's suction pressure every N seconds, and transmits the monitored user's suction pressure to the processor 210 .

In one embodiment, the maximum suction pressure obtained within the first preset time can be used as the suction negative pressure, the suction negative pressure can be used as the suction parameter, and the user's suction negative pressure can be judged within this time. , and analyze the user's suction habits. Specifically, the maximum suction pressure obtained within the first preset time, that is, the suction negative pressure, can be compared with the preset suction parameter range corresponding to the control mode to determine the suction Whether the parameters meet the preset suction parameter range corresponding to the control mode, if so, the control mode will be entered directly, and the atomization process of the atomizer 100 will work in the control mode. In other embodiments, all suction pressures obtained within the first preset time can also be used as suction negative pressures, and all suction negative pressures can be used as suction parameters. That is, in this embodiment, the suction parameters only include suction negative pressure. It can be understood that instead of using all the suction pressures obtained within the first preset time as the suction negative pressure, only the maximum suction pressure is used as the suction negative pressure, and the suction negative pressure is used as the suction parameter to determine the The method and steps for determining whether the suction parameters meet the preset suction parameter range of the control mode are simpler and more efficient.

Optionally, the user's suction pressure can be obtained every N seconds during 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 a certain suction parameter does not meet the preset suction parameter range, the control mode will be exited directly.

It can be understood that in this method, the suction negative pressure obtained during the first preset time of each suction action of the user is used as a parameter to judge the user's suction habit. After the first preset time of each suction action of the user, You can enter the selected control mode to meet the user's smoking habits.

In another embodiment, as shown in Figure 5, the step of obtaining the user's puff parameters each time in step S1 includes:

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

Specifically, the airflow sensor 250 monitors the user's suction negative pressure every N seconds, and transmits the monitored user's suction negative pressure to the processor 210 . Among them, N is less than or equal to 0.1, that is, the user's suction negative pressure is obtained at least every 0.1 seconds.

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

Specifically, the suction time corresponding to each suction action performed by the user, that is, the total suction duration, is monitored and recorded, the total duration of each suction action by the user is regarded as the suction time, and then the suction time and step S11 are The suction negative pressure obtained in is used as the suction parameter, that is, in this embodiment, the suction parameters include suction time and suction negative pressure. The total puffing time of each puffing action of the user can be the duration for which the suction airflow generated by each puffing action of the user detected by the airflow sensor 250 meets a certain threshold, which is used as the puffing time. By obtaining the user's suction negative pressure every N seconds and recording the total suction duration of each user's suction, the user's suction parameters are obtained to facilitate judgment during the subsequent atomization process. It can be understood that in this method, since all suction negative pressures in the entire suction process and the total time of a puff are taken into account, the judgment of the user's smoking habits is more accurate. However, the above parameters cannot be obtained until the user has taken at least one puff. Therefore, the user must take at least one puff, that is, the next puff can be entered into the selected control mode.

Specifically, in step S11, the user's suction negative pressure can be obtained every N seconds during the first preset time when the user starts suctioning, or the user's suction negative pressure can be obtained every N seconds during the entire process of each suction by the user. suction negative pressure. It can be understood that if the user's suction negative pressure is obtained as a suction parameter every N seconds during the first preset time when the user starts suctioning, the judgment step can be simplified.

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

Specifically, the atomization parameters of the atomizer 100 include any one or more of the liquid supply rate of the spray assembly 13 , the liquid supply amount of the spray assembly 13 , and the atomization power of the atomization core 12 . The liquid supply rate of the spray assembly 13 is the mass of the aerosol-generating matrix that the spray assembly 13 sprays to the atomization core 12 per unit time; the liquid supply volume of the spray assembly 13 is the amount of liquid the spray assembly 13 sprays to the atomization core 12 every time the user takes a puff. The total mass of the aerosol-generating matrix. That is to say, the processor 210 controls the aerosol injected by the injection assembly 13 to the atomizing core 12 per unit time according to the obtained suction negative pressure of each suction action of the user and/or the suction parameters of the suction time. The mass of the aerosol-generating matrix is generated, and/or the total mass of the aerosol-generating matrix ejected from the spray assembly 13 to the atomizing core 12 by the user each time the user inhales. 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 injection assembly can be controlled simultaneously. The atomization parameters of the atomizer 100 are controlled by the liquid supply rate of 13, the liquid supply volume of the spray assembly 13, and the atomization power of the atomization core 12, so as to meet the atomization needs of the user under different suction parameters.

Further, the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters in the above step S2 specifically includes:

Control the liquid supply rate and/or liquid supply volume of the spray component according to the suction parameters, and control the atomization power of the atomization core.

Specifically, the atomization parameters include not only the liquid supply rate and/or liquid supply volume of the spray assembly 13, but also the atomization power of the atomization core 12. The processor 210 not only controls the liquid supply rate and/or liquid supply volume of the spray assembly 13, but also controls the mist according to the obtained suction negative pressure and/or suction time parameters of each suction action of the user. The atomization power of the chemical core 12. In one embodiment, the atomization core 12 includes a heating element. The heating element is used to heat the atomized aerosol generating matrix to generate aerosol. The heating element can be any structure such as a heating plate, a heating mesh, a heating film, etc. The atomization power of the core 12 is the heating power of the heating element. The heating control unit 243 of the controller 240 controls the heating power of the heating element so that the heating power of the heating element matches the liquid supply rate of the injection assembly 13 to meet the user's actual needs. The suction demand enables the atomizer 100 to perform atomization work better and improves the atomization taste of the atomizer 100 .

For example, if the suction negative pressure in the obtained user's suction parameters is relatively large, the liquid supply speed of the injection assembly 13 can be controlled. The rate and the heating power of the heating element are larger values, so that the atomization efficiency of the atomizer 100 is higher, and the amount of aerosol generated by heating atomization per unit time is larger, which avoids insufficient aerosol generated by atomization and cannot meet the requirements. The user's suction needs; if the suction negative pressure in the obtained user's suction parameters is small, the liquid supply rate of the spray assembly 13 and the heating power of the heating element can be controlled to a small value, so that the mist of the atomizer 100 When the atomization efficiency is within a suitable range, the amount of aerosol generated by heating and atomization per unit time does not need to be too much, as long as it can meet the user's needs. This avoids the atomization efficiency being too high and the amount of aerosol generated being too large when the heating power is too large. , the user cannot pump enough, resulting in waste.

In addition, according to the length of the suction time, the liquid supply time of the spray assembly 13 can be controlled, that is, the liquid supply amount of the spray assembly 13 can be controlled to satisfy users with different suction habits. For example, if the user inhales for 5 seconds each time, after detecting the start of inhalation, the injection assembly 13 is controlled to continue injecting for 5 seconds and then automatically stops.

In one embodiment, the spray assembly 13 includes a micropump 131 and a nozzle 132. The micropump 131 and the nozzle 132 are in gas communication. The micropump 131 is used to provide a high-speed air flow to the nozzle 132. The aerosol-generating matrix in the liquid storage bottle 14 is transferred to The position of the nozzle 132 is sprayed by the micro-pump 131 to the heating element for heating and atomization. The rotation speed of the micro-pump 131 determines the liquid supply rate of the injection assembly 13 to the atomization core 12. The faster the rotation speed of the micro-pump 131, the greater the spray speed. The faster the liquid supply rate of the component 13 to the atomizing core 12 is, that is, the greater the quality of the aerosol-generating matrix that the spraying component 13 sprays to the atomizing core 12 per unit time, the speed of the spraying component 13 can be controlled by controlling the rotational speed of the micropump 131 Liquid supply rate. At the same time, the rotational speed and rotation time of the micropump 131 jointly determine the liquid supply volume of the spray assembly 13, that is, the total mass of the aerosol-generating matrix sprayed by the spray assembly 13 to the atomizing core 12 every time the user inhales, can be controlled by simultaneously controlling the micropump 131. The rotation speed and rotation time of the pump 131 control the liquid supply amount of the injection assembly 13 .

In another embodiment, the spray assembly 13 includes a spray head, which has a structure similar to that of a hairspray device. The liquid storage bottle 14 is a high-pressure liquid storage tank. The aerosol-generating matrix in the liquid storage tank exists under high-pressure conditions. The spray head passes through a pipeline. It is connected to the high-pressure liquid storage tank, and a switch is provided on the pipeline. By controlling the switch, the aerosol-generating matrix in the high-pressure liquid storage tank can be sprayed through the nozzle to the atomizing core 12 to form droplets, and the atomizing core 12 heats the droplets to generate gas. sol. The opening degree of the nozzle can be adjusted and controlled, and the opening degree of the nozzle can be controlled according to the obtained user's suction parameters to control the liquid supply rate of the spray assembly 13. For example, the greater the opening degree of the nozzle, the more mist the spray assembly 13 will spray per unit time. The mass of the aerosol-generating matrix injected by the chemical core 12 is greater. The amount of liquid supplied to the spray assembly 13 is controlled by simultaneously controlling the opening degree and opening time of the nozzle. For example, the smaller the opening degree of the nozzle, the shorter the opening time of the nozzle. Each time the user inhales, the spray assembly 13 injects the atomizing core 12 The smaller the total mass of the aerosol-generating matrix.

It can be understood that the rotation speed of the micro pump 131 and/or the rotation speed and rotation time of the micro pump 131 are controlled according to the obtained suction parameters of the user, or the opening degree and opening degree of the nozzle are controlled according to the obtained suction parameters of the user. / Or the opening degree and opening time, and then control the liquid supply rate and / or liquid supply volume of the spray component 13 , so that the quality of the aerosol-generating matrix sprayed by the spray component 13 to the atomizing core 12 per unit time and / or the user's every puff The total mass of the aerosol-generating matrix injected by the primary injection component 13 to the atomizing core 12 can reach the value actually required by the user, and meet the user's actual suction needs.

Furthermore, the atomizer 100 stores at least one control mode, and the control mode includes a preset corresponding relationship between the suction parameter range and the atomization parameter, that is, the suction parameter range and the atomization parameter have a one-to-one correspondence. The step of controlling the atomization parameters of the atomizer according to the suction parameters described in step S2 above includes:

In response to the suction parameter during suction being satisfied and the suction parameter range of one of the control modes exceeding the first preset number of times, the control mode is entered.

Specifically, the suction parameters include suction negative pressure and the total suction duration of each suction by the user, that is, the suction time. The atomizer 100 stores at least one control mode, and each control mode includes its corresponding suction parameter range and atomization parameter. According to the user's suction parameters obtained multiple times, the suction parameters of the multiple user suction actions are compared with the suction parameter range of the control mode. If the suction parameters of the multiple suction actions meet the requirements of one of the control modes, If the number of puffs in the parameter range exceeds the first preset number, the atomizer 100 enters the control mode, and the atomizer 100 is controlled to perform atomization work with the atomization parameters corresponding to the puff parameter range in the control mode.

It can be understood that the suction parameters of the multiple suction actions satisfy that the suction parameter range of one of the control modes exceeds the first preset number of times, and it can be that the suction parameters of the multiple consecutive suctions are all within the suction parameters of the control mode. range and the number of consecutive times exceeds the first preset number, for example, the first preset number is five, and the suction parameters of the six consecutive suctions are all within the suction parameter range of one of the control modes, that is, it is determined to be multiple suctions. The control mode is entered when the suction parameter range of the control mode exceeds the first preset number of times; alternatively, it can also be the suction parameter that exceeds the first preset number of times among the suction parameters of multiple suctions. Satisfy the suction parameter range of one of the control modes, for example, the first preset number of times is seven, and the suction parameters of more than seven suctions out of ten suctions meet the suction parameter range of one of the control modes, That is, it is determined that the suction parameters for multiple suctions satisfy the suction parameter range in this control mode and exceeds the first preset number of times, and the control mode is entered; the design can be based on specific needs, and the first preset number of times can also be based on experience. Default.

Specifically, the suction curve can be formed by fitting or selection. For example, there is a certain correspondence between the suction parameter range and the atomization parameter. Different suction parameter ranges correspond to different atomization parameters. According to the monitored suction parameters of multiple puffs, when multiple puffs are When the number of times the puffing parameters satisfy the puffing parameter range of a certain control mode exceeds the first preset number of times, the corresponding puffing parameter range of the control mode is calculated based on the correspondence between the puffing parameter range and the atomization parameter. The atomization parameters are calculated using the formula method to obtain the corresponding atomization parameters, thereby fitting the suction curve. Alternatively, the atomizer 100 may pre-store multiple preset relationship curves between the suction parameter ranges and the atomization parameters, and directly select the corresponding relationship curve, that is, the suction curve, based on the suction parameter range of the control mode. It can be understood that since the processor 210 of the electronic atomization device 300 generally has limited computing power, multiple preset corresponding relationship curves between the suction parameter range and the atomization parameter are stored in advance, and the matching curve is selected according to the suction parameter range during actual use. The curve makes the calculation of the processor 210 simple and improves the processing efficiency. The corresponding relationship curves between multiple preset suction parameter ranges and atomization parameters can be formed in advance through multiple experiments and computer fitting.

The processor 210 enters the control mode in response to the suction parameters of multiple suctions satisfying the suction parameter range in one of the control modes exceeding the first preset number of times, according to the suction parameter range and mist included in the control mode. According to the corresponding relationship between the atomization parameters, the atomizer 100 is controlled to perform atomization work with the corresponding atomization parameters. The corresponding relationship between the suction parameter range and the atomization parameter can be a table or a curve.

In this application, the atomizer 100 stores at least one control mode, and each control mode includes a preset corresponding relationship between the suction parameter range and the atomization parameter. In one embodiment, the suction parameters include two parameters, namely suction negative pressure and suction time. The suction negative pressure includes two preset intensity thresholds Pa and Pb, and the suction time includes a preset time threshold Ta. , according to the two preset intensity thresholds Pa and Pb, the suction negative pressure is divided into three preset intensity threshold ranges, which are the first preset intensity threshold range P<Pa and the second preset intensity threshold range Pa≤P< Pb, the third preset intensity threshold range P≥Pb; according to the preset time threshold Ta, the suction time is divided into two preset time threshold ranges, respectively, the first preset time threshold range T<Ta, the second preset time threshold range The time threshold range is T≥Ta. The atomizer 100 includes six control modes, which are the first control mode L1, the second control mode L2, and the sixth control mode L6. As shown in the table below, the suction parameter range of the first control mode L1 is that the suction negative pressure is within the first preset intensity threshold range and the suction time is within the first preset time threshold range, that is, the suction range of the first control mode L1 The parameter range is P<Pa, T<Ta; the suction parameter range of the second control mode L2 is that the suction negative pressure is within the first preset intensity threshold range, and the suction time is within the second preset time threshold range, that is, the second The suction parameter range of the 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 within the second preset intensity threshold range, and the suction time is within the first preset time. The 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 described again.

The suction parameter range of each control mode has corresponding atomization parameters. The atomization parameters include the liquid supply rate of the injection assembly 13, the liquid supply volume of the injection assembly 13, and the atomization power of the atomization core 12. As shown in the table below, 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 volume M1 and the first atomization power W1. In the first control mode L1, the atomizer 100 is controlled at the first liquid supply rate V1, The first liquid supply volume M1 and the first atomization power W1 are operated, and the atomizer 100 is controlled in the sixth control mode L6 to use the sixth liquid supply rate V6, the sixth liquid supply volume M6, and the sixth atomization power. W6 does the work.

The user's puffing habits can be analyzed and judged according to the obtained puffing parameters of the user's multiple puffs and the puffing parameter ranges of the above six control modes, and the atomizer 100 can be controlled to work in the corresponding control mode. For example, the first preset number of times is five, and the obtained suction parameters of the user's multiple suctions satisfy that the suction negative pressure is in the range of Pa≤P<Pb, and the suction time is in the range of T<Ta If the number exceeds five times, the atomizer 100 enters the third control mode L3, and the atomizer 100 is controlled to use the third atomization parameters, that is, the third liquid supply rate V3, the third liquid supply volume M3, and the third atomization power W3. Atomization.

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. The suction parameter ranges of each control mode are different. The suction parameters obtained by the user for multiple suctions are compared with the suction parameter ranges preset for multiple control modes. The suction parameters for multiple suctions satisfy multiple control modes. If the number of puffs in a certain control mode exceeds the first preset number, the control mode is entered, and the atomizer 100 is controlled to work using the atomization parameters of the control mode.

Furthermore, the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters in step S2 also includes:

In response to the suction parameter during suction not satisfying the suction parameter range in the control mode exceeding the second preset number of times, the control mode is exited.

Specifically, after entering the control mode, the airflow sensor 250 still monitors the user's suction action to monitor the user's suction parameters such as negative pressure and suction time each time, and the processor 210 obtains the information monitored by the airflow sensor 250 The user's puff parameters for each time.

Compare the obtained suction parameters of the user for multiple suctions with the suction parameter range of the control mode in which the user is located. The suction parameters of the multiple suctions do not satisfy that the suction parameter range of the control mode exceeds the second preset number of times. When , the atomizer 100 exits the control mode, that is, when the number of times the acquired puffing parameters of the user's multiple puffs are not within the puffing parameter range of the control mode exceeds the second preset number of times, the atomizer 100 exits the control mode.

The suction parameters of multiple suctions do not satisfy the suction parameter range of the control mode in which they are located and exceeds the second preset number of times. This may be that the suction parameters of multiple consecutive suctions are not within the suction parameter range of the control mode and If the number of consecutive times exceeds the second preset number, for example, the second preset number is two times, and the suction parameters of three consecutive suctions are not within the suction parameter range of the control mode, that is, the suction parameters are determined to be multiple suctions. If the suction parameter range of the control mode is not satisfied and exceeds the second preset number of times, exit the control mode; alternatively, it can also be the suction parameters of the multiple suction ranges. The suction parameters that exceed the second preset number of times do not meet the suction parameter range of the control mode in which they are located. For example, the second preset number is three times, and the suction parameters that exceed three times among the ten suctions do not meet the suction parameter range of the control mode. If it meets the suction parameter range of the control mode it is in, that is, it is determined that the suction parameters for multiple suctions do not meet the suction parameter range of the control mode it is in for more than the second preset number of times, it will exit the control mode; it can be based on Specific needs need to be designed, and the second preset number can also be preset based on experience.

In one embodiment, the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters described in step S2 includes:

S21: During the rising stage of the user's suction negative pressure, in response to the difference ΔP of the user's suction negative pressure rise being greater than the first negative pressure threshold Ps within the second preset time, the atomizer is controlled to stop atomization.

Specifically, the suction negative pressure is obtained at certain intervals during the entire process of the user's suction action. During the rising stage of the user's suction negative pressure, that is, the last suction negative pressure is greater than the previous suction negative pressure. stage, when the difference ΔP of the increase in the user's suction negative pressure 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 stage during the user's suction action, the difference ΔP of the user's suction negative pressure rise within any second preset time is greater than the first negative pressure threshold Ps , it can be determined that the user has stopped the suction action, and the atomizer 100 can be directly controlled to stop the atomization work in advance, which is beneficial to saving energy. Among them, the controller 240 controls the atomizer 100 to stop atomization, the spray assembly control unit 241 of the controller 240 controls the spray assembly 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 advance. Stopping the heating and atomization process helps save energy. For example, the second preset time is 0.3 seconds, and the first negative pressure threshold Ps is 800 Pa. During the user's suction negative pressure rising stage, the difference ΔP of the suction negative pressure rise in any 0.3 second period is greater than 800 Pa, that is, the atomizer 100 is controlled to stop atomizing at the last time point of 0.3 seconds.

Referring to FIG. 6 , in one embodiment, the airflow sensor 250 monitors the user's suction negative pressure every 0.1 seconds. The processor 210 obtains the suction negative pressure monitored at multiple time points from the airflow sensor 250 and converts the suction negative pressure into the suction negative pressure. The negative pressure-time curve is obtained by fitting the pressure and the corresponding time points as shown in Figure 6. Every time the user performs a suction action, the suction negative pressure basically decreases first and then increases. In the prior art, when the user performs a suction action, the suction negative pressure at which the user stops suctioning is set to a fixed negative pressure threshold, and whether the user stops the suctioning action is determined based on the stop suction negative pressure threshold. When the suction negative pressure reaches the suction stop negative pressure threshold, it indicates that the user has stopped the suction action, and then controls the atomizer to stop atomization. For example, as shown in Figure 6, the starting negative pressure of the atomizer 100 is -300 Pa, and the negative pressure threshold for stopping suction is also -300 Pa. The atomization can only be controlled when the user's suction negative pressure reaches -300 Pa again. The device 100 stops atomizing, that is, the atomization can be stopped at the nineteenth time point D3 in Figure 8 .

In the control method of the atomizer 100 provided in this embodiment, when the difference ΔP of the increase in the user's suction negative pressure during the second preset time is monitored to be greater than the first negative pressure threshold Ps, that is, the second preset time When the difference ΔP between the suction negative pressures corresponding to the last time point and the first time point is greater than the first negative pressure threshold Ps, the atomizer 100 is controlled to stop atomization. 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 suction negative pressures of the seventeenth time point D2 and the sixteenth time point D1 are If the rising difference ΔP is greater than the first negative pressure threshold Ps, the atomizer 100 is immediately controlled to stop atomization at the last time point of the second preset time, that is, the seventeenth time point D2. It can be seen from Figure 6 that by using the control method of the atomizer 100 provided by the present application to control the atomizer 100, the time point at which the atomizer 100 stops atomizing is earlier than the time point at which the atomizer stops atomizing in the prior art. The atomizer 100 can be controlled in advance to stop atomization and save energy.

For the same user, the negative pressure-time curve is usually the same, while the negative pressure-time curves of different users are usually different. Compared with the existing technology that uses the stop suction negative pressure threshold to determine whether the user stops suctioning, this application uses the difference ΔP between the user's suction negative pressure rise within the second preset time and the first negative pressure threshold Ps The method of judging whether the user stops smoking is more intelligent and can be more adapted to different user groups. It can perform adaptive control for different user groups and improve the performance of the atomizer 100.

Referring to Figure 7, in one embodiment, the mist of the atomizer 100 is controlled according to the suction parameters described in step S2. The steps of parameterization include the above step S21 and then include:

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.

Specifically, according to the last time point of the second preset time when the user's suction negative pressure rise difference ΔP is greater than the first negative pressure threshold Ps in step S21, the suction negative pressure corresponding to this time point is recorded. This serves as the second negative pressure threshold. As shown in FIG. 6 , the suction negative pressure (for example, minus 1100 Pa) corresponding to the last time point of the second preset time, that is, the seventeenth time point D2, is recorded as the second negative pressure threshold.

S23: In response to the subsequent user's suction negative pressure being greater than the second negative pressure threshold, control the atomizer to stop atomization.

Specifically, during the subsequent suction action of the user, the user's suction negative pressure and the second negative pressure threshold are determined based on the suction negative pressure obtained at certain intervals. When the user's suction negative pressure When it is greater than the second negative pressure threshold, it indicates that the user has stopped the suction action, and the controller 240 immediately controls the atomizer 100 to stop atomizing, which is beneficial to saving energy.

It can be understood that in this embodiment, the user's suction 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 determining whether the user stops the suction action. Then, it is determined when the atomizer stops atomizing. Compared with each puffing action, whether the difference ΔP of the user's puffing negative pressure rise within the above-mentioned second preset time is greater than the first negative pressure threshold Ps. The judgment process of judging whether the user stops smoking is simpler and more efficient.

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

The user's suction negative pressure is obtained at regular intervals.

Specifically, when the user performs a suction action, the airflow sensor 250 monitors the user's suction negative pressure at regular intervals during the entire process of a suction action, and monitors the user's suction negative pressure multiple times during the entire process of a suction action. The user's suction negative pressure is to monitor the user's suction negative pressure at multiple time points. The processor 210 obtains the suction negative pressure monitored at multiple time points from the airflow sensor 250 . For example, the user's suction negative pressure can be monitored every 0.1 seconds during the entire process of the user's suction action, and the processor 210 obtains the suction pressure at multiple time points monitored every 0.1 seconds during the entire process of the user's suction action. Suction negative pressure.

Referring to Figure 8, the step of controlling the atomization parameters of the atomizer 100 according to the suction parameters described in step S2 includes:

S21b: Generate a negative pressure-time curve based on the suction negative pressure and the corresponding time point.

Specifically, based on the above-mentioned suction negative pressure monitored at certain intervals during the entire process of the user's suction movement, the suction negative pressure at multiple time points during the entire process of the user's suction movement was obtained. The suction negative pressure at multiple corresponding time points is obtained, and a negative pressure-time curve is generated by fitting. The vertical axis of the negative pressure-time curve represents the suction negative pressure, and the horizontal axis represents the corresponding time point.

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

Specifically, based on the negative pressure-time curve generated by the above fitting, the slope between two adjacent points on the curve is obtained.

S23b: In response to the slope being greater than the slope threshold, the atomizer is controlled to stop atomizing.

Specifically, based on the obtained slope of the curve, the obtained slope and the slope threshold are determined. When the obtained slope is greater than the slope threshold, the controller 240 controls the atomizer 100 to stop the atomization operation. In a specific implementation, the atomizer 100 can be controlled to stop atomizing when the slope between two adjacent points in the negative pressure-time curve is greater than the slope threshold; it can also be controlled based on the entire negative pressure-time curve. At four consecutive time points, that is, when the slopes of three consecutive time periods are greater than the slope threshold, the atomizer 100 is controlled to stop the atomization operation to avoid misjudgment of a sudden slope change caused by the user's ventilation or coughing as stopping vaping. suck. Among them, the injection assembly control unit 241 of the controller 240 controls the injection assembly 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 the heating and atomization process, which is beneficial to saving energy. The slope of the negative pressure-time curve in this embodiment is greater than the slope threshold, which means that the difference ΔP of the increase in suction negative pressure within the second preset time in the above embodiment is greater than the first negative pressure threshold Ps. , both indicate a sudden change in the user's suction negative pressure.

It is understandable that even the same user may use different suction methods, that is, have different negative pressure-time curve. Therefore, using the slope to determine if the user stops puffing is more accurate than setting the second negative pressure threshold to determine if the user stops puffing.
