The present application provides a control method of an atomizer 100, which is used for a power supply assembly 200 of an active liquid supply type electronic atomization device 300, so that the electronic atomization device 300 can realize adaptive control on different user groups. As shown in fig. 4, the control method of the atomizer 100 includes:

s1: the user's aspiration parameters are obtained each time.

Specifically, the suction parameters include suction negative pressure and/or suction time, the suction negative pressure is suction negative pressure generated when the user performs a suction action, the suction time is total suction duration of each suction action performed by the user, the suction negative pressure generated when the user performs each suction action and the time of each suction are monitored by the airflow sensor 250, and the processor 210 obtains the suction negative pressure and/or suction time of each suction action of the user from the airflow sensor 250 so as to control a subsequent atomization process. The step of acquiring the parameters of each suction of the user may be performed during a certain period of time during which the suction is performed once, or may be performed during the whole process of the suction once.

In one embodiment, the step of acquiring the user' S aspiration parameters in step S1 includes:

and in a first preset time when the user starts sucking, acquiring the sucking pressure of the user every N seconds, taking the maximum sucking pressure as the sucking negative pressure, and taking the sucking negative pressure as the sucking parameter.

Specifically, the suction pressure of the user 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, i.e. the user's suction pressure is acquired at least once every 0.2 seconds during the time of 0.5 seconds. Preferably, N is equal to or less than 0.1, i.e. the user's suction pressure is taken at least once every 0.1 seconds. That is, the airflow sensor 250 monitors the user's suction pressure every N seconds for a first preset time and transmits the monitored user's suction pressure to the processor 210.

In an embodiment, the maximum suction pressure obtained in the first preset time may be used as the suction negative pressure, the suction negative pressure is used as the suction parameter, the suction negative pressure of the user is determined in the time, the suction habit of the user is analyzed, specifically, the maximum suction pressure obtained in the first preset time, that is, the suction negative pressure, may be compared with the preset suction parameter range corresponding to the control mode, whether the suction parameter meets the preset suction parameter range corresponding to the control mode or not is determined, if yes, the control mode is directly entered, and the atomization process of the atomizer 100 works in the control mode. In other embodiments, all the suction pressures acquired in the first preset time may be used as the suction negative pressure, and all the suction negative pressures may be used as the suction parameters. I.e. in this embodiment the suction parameters only comprise suction negative pressure. It can be appreciated that the method and steps for determining whether the suction parameter satisfies the preset suction parameter range of the control mode are simpler and more efficient than taking all suction pressures acquired in the first preset time as the suction negative pressure, taking only the maximum suction pressure as the suction negative pressure, and taking the suction negative pressure as the suction parameter.

Optionally, the suction pressure of the user may be obtained every N seconds in a first preset time of each suction action of the user, the maximum suction pressure in the first preset time is taken as the suction negative pressure, whether the suction parameter of each suction action meets the preset suction parameter range of the control mode is judged, and if the suction parameter of a certain time does not meet the preset suction parameter range, the control mode is directly exited.

It can be understood that in the method, the suction negative pressure obtained in the first preset time of each suction action of the user is adopted as the parameter for judging the suction habit of the user, and the user can enter the selected control mode after the first preset time of each suction action of the user, so that the suction habit of the user is met.

In another embodiment, as shown in fig. 5, the step of acquiring the user' S aspiration parameters in step S1 includes:

s11: the suction negative pressure of the user is acquired every N seconds.

Specifically, the airflow sensor 250 monitors the suction negative pressure of the user once every N seconds and transmits the monitored suction negative pressure of the user to the processor 210. Wherein N is less than or equal to 0.1, i.e. the suction negative pressure of the user is acquired at least once every 0.1 seconds.

S12: recording the total pumping duration of each pumping time of a user as pumping time; suction negative pressure and suction time are taken as suction parameters.

Specifically, the total suction time corresponding to each suction action performed by the user is monitored and recorded, the total time of each suction action performed by the user is taken as the suction time, and then the suction time and the suction negative pressure obtained in step S11 are taken as the suction parameters, i.e. in this embodiment, the suction parameters include the suction time and the suction negative pressure. The total pumping duration of each pumping action of the user may be a duration that the pumping airflow generated by each pumping action of the user and monitored by the airflow sensor 250 meets a certain threshold, which is taken as pumping time. The suction negative pressure of the user is obtained every N seconds, and the total suction duration of each suction of the user is recorded, so that the suction parameters of each time of the user are obtained, and the judgment in the follow-up atomization process is facilitated. It will be appreciated that in this method, the determination of the user's pumping habit is more accurate, as all of the negative pumping pressure and the total time to pump a bite are taken into account throughout the pumping process. However, the above parameters need to be obtained after the user has at least sucked a single bite, and therefore the user can start to enter the selected control mode after at least sucking a single bite, i.e., the next bite.

Specifically, in step S11, the suction negative pressure of the user may be acquired every N seconds within the first preset time when the user starts suction, or may be acquired every N seconds during the whole process of every suction of the user. It is understood that the judgment step can be made simple if the suction negative pressure of the user is acquired as the suction parameter every N seconds within the first preset time for the user to start suction.

S2: and controlling 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 a liquid supply rate of the spray assembly 13, a liquid supply amount of the spray assembly 13, and an atomization power of the atomizing core 12. The liquid feed rate of the spray assembly 13 is the mass of aerosol-generating substrate sprayed by the spray assembly 13 onto the atomizing core 12 per unit time; the amount of liquid supplied by the spray assembly 13 is the total mass of aerosol-generating substrate sprayed by the spray assembly 13 onto the atomizing core 12 per puff by the user. That is, the processor 210 controls the mass of aerosol-generating substrate ejected by the ejection assembly 13 toward the atomizing core 12 per unit time and/or controls the total mass of aerosol-generating substrate ejected by the ejection assembly 13 toward the atomizing core 12 per puff of the user based on the acquired puff parameters of the puff negative pressure and/or puff time per puff of the user. It will be appreciated that the atomization parameters of the atomizer 100 may be controlled by controlling one of the liquid supply rate of the spray assembly 13 and the liquid supply amount of the spray assembly 13 and the atomization power of the atomizing core 12, or the atomization parameters of the atomizer 100 may be controlled by controlling the liquid supply rate of the spray assembly 13 and the liquid supply amount of the spray assembly 13 and the atomization power of the atomizing core 12 simultaneously, so as to meet the needs of the user for atomization under different suction parameters.

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

the liquid supply rate and/or the liquid supply amount of the spraying assembly are/is controlled according to the suction parameters, and the atomization power of the atomization core is controlled.

In particular, the atomizing parameters include not only the liquid supply rate and/or the liquid supply amount of the spray assembly 13, but also the atomizing power of the atomizing core 12. The processor 210 is required to control not only the liquid supply rate and/or the liquid supply amount of the spray module 13, but also the atomizing power of the atomizing core 12 according to the acquired suction parameters of the suction negative pressure and/or the suction time of each suction action of the user. In an embodiment, the atomizing core 12 includes a heating element, where the heating element is used to heat the atomized aerosol generating substrate to generate aerosol, the heating element may be any structure of a heating plate, a heating net, a heating film, etc., the atomizing power of the atomizing core 12 is the heating power of the heating element, and 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 is matched with the liquid supply rate of the spraying component 13, so as to meet the actual pumping requirement of the user, so that the atomizer 100 can perform atomization better, and the atomizing taste of the atomizer 100 is improved.

For example, the acquired suction negative pressure in the suction parameters of the user is larger, and the liquid supply rate of the jet assembly 13 and the heating power of the heating element can be controlled to be larger, so that the atomization efficiency of the atomizer 100 is higher, the quantity of aerosol generated by heating and atomization in unit time is larger, the shortage of aerosol generated by atomization is avoided, and the suction requirement of the user cannot be met; if the suction negative pressure in the acquired suction parameters of the user is smaller, the liquid supply rate of the jet assembly 13 and the heating power of the heating element can be controlled to be smaller, so that the atomization efficiency of the atomizer 100 is in a proper range, the quantity of aerosol generated by heating and atomization in unit time is not too large, the user requirement can be met, the situation that the atomization efficiency is too high when the heating power is too large, the quantity of generated aerosol is too large, and the user cannot suck the aerosol to cause waste is avoided.

In addition, according to the length of the pumping time, the liquid supply time of the spraying component 13, that is, the liquid supply amount of the spraying component 13 can be controlled to meet the users with different pumping habits. For example, if the user draws for 5 seconds each time, the control unit 13 automatically stops the injection for 5 seconds after detecting the start of the drawing.

In an embodiment, the spraying component 13 includes a micro pump 131 and a nozzle 132, the micro pump 131 is in gas communication with the nozzle 132, the micro pump 131 is used for providing high-speed airflow for the nozzle 132, the aerosol generating substrate in the liquid storage bottle 14 is transported to the position of the nozzle 132, and is sprayed to the heating element by the nozzle 132 for heating and atomization after being acted by the micro pump 131, the liquid supply rate of the spraying component 13 to the atomizing core 12 is determined by the rotation speed of the micro pump 131, and the liquid supply rate of the spraying component 13 to the atomizing core 12 is higher as the rotation speed of the micro pump 131 is higher, namely the mass of the aerosol generating substrate sprayed by the spraying component 13 to the atomizing core 12 in unit time is higher, and the liquid supply rate of the spraying component 13 can be controlled by controlling the rotation speed of the micro pump 131. Meanwhile, the rotation speed and the rotation time of the micro pump 131 jointly determine the liquid supply amount of the spray assembly 13, that is, the total mass of the aerosol-generating substrate sprayed by the spray assembly 13 to the atomizing core 12 every time the user sucks, and the liquid supply amount of the spray assembly 13 can be controlled by simultaneously controlling the rotation speed and the rotation time of the micro pump 131.

In another embodiment, the spraying assembly 13 comprises a spraying head, the spraying head is similar to the spraying head structure of the hair spray device, the liquid storage bottle 14 is a high-pressure liquid storage tank, aerosol generating substrates in the liquid storage tank exist under the high-pressure condition, the spraying head is communicated with the high-pressure liquid storage tank through a pipeline, a switch is arranged on the pipeline, the aerosol generating substrates in the high-pressure liquid storage tank can be sprayed to the atomizing core 12 through the spraying head to form liquid drops through the control switch, and the liquid drops are heated by the atomizing core 12 to generate aerosol. The degree of opening of the spray head may be controlled in an adjustable manner, and the rate of liquid supply to the spray assembly 13 may be controlled in response to the obtained user's suction parameters, e.g. the greater the degree of opening of the spray head, the greater the mass of aerosol-generating substrate sprayed by the spray assembly 13 onto the atomizing core 12 per unit time. The amount of liquid supplied by the spray assembly 13 is controlled by controlling both the degree of opening and the time of opening of the spray head, e.g. the smaller the degree of opening of the spray head, the smaller the time of opening of the spray head, the smaller the total mass of aerosol-generating substrate sprayed by the spray assembly 13 towards the atomizing core 12 per puff by the user.

It will be appreciated that the actual user's suction needs may be met by controlling the rotational speed of the micro pump 131 and/or the rotational speed and rotational time of the micro pump 131 according to the obtained user's suction parameters, or by controlling the opening degree and/or the opening degree and the opening time of the spray head according to the obtained user's suction parameters, and thus controlling the liquid supply rate and/or the liquid supply amount of the spray assembly 13, so that the mass of the aerosol-generating substrate sprayed onto the atomizing core 12 per unit time by the spray assembly 13 and/or the total mass of the aerosol-generating substrate sprayed onto the atomizing core 12 by the spray assembly 13 per unit time by the user may reach the actual user's required values.

Further, the atomizer 100 stores at least one control mode, where the control mode includes a preset correspondence between a pumping parameter range and an atomization parameter, that is, the pumping parameter range and the atomization parameter are in a one-to-one correspondence. The step of controlling the atomization parameter of the atomizer according to the suction parameter in the step S2 includes:

the control mode is entered in response to the pumping parameters at pumping meeting a pumping parameter range for one of the control modes exceeding a first preset number of times.

In particular, the suction parameters include suction negative pressure and total suction duration per suction of the user, i.e. suction time. The nebulizer 100 stores at least one control pattern, each control pattern comprising its corresponding range of suction parameters and nebulization parameters. Comparing the suction parameters of the suction actions of the user and the suction parameter ranges of the control modes according to the suction parameters of the user acquired for a plurality of times, and if the number of times that the suction parameters of the suction actions meet the suction parameter ranges of one of the control modes exceeds a first preset number of times, entering the control mode by the atomizer 100, and controlling the atomizer 100 to perform atomization work according to atomization parameters corresponding to the suction parameter ranges of the control mode.

It may be appreciated that the suction parameters of the multiple suction actions satisfy that the suction parameter range in one of the control modes exceeds the first preset number of times, which may be that the suction parameters of the continuous multiple suction are all in the suction parameter range in the control mode and the continuous number of times exceeds the first preset number of times, for example, the first preset number of times is five, and the suction parameters of the continuous six suction are all in the suction parameter range in one of the control modes, that is, it is determined that the suction parameters of the multiple suction satisfy that the suction parameter range in the control mode exceeds the first preset number of times, and the control mode is entered; alternatively, the suction parameter exceeding the first preset number of times among the suction parameters of the plurality of times of suction may satisfy the suction parameter range in one of the control modes, for example, the first preset number of times is seven, and the suction parameter exceeding the seventh number of times of suction among the ten times of suction satisfies the suction parameter range in one of the control modes, that is, it is determined that the suction parameter of the plurality of times of suction satisfies the suction parameter range exceeding the first preset number of times in the control mode, and the control mode is entered; the design can be performed according to specific needs, and the first preset times can also be preset according to experience.

In particular, the suction curve may be formed by fitting or by alternative means. For example, there is a certain correspondence between the pumping parameter ranges and the atomizing parameters, different pumping parameter ranges correspond to different atomizing parameters, and when the number of times that the pumping parameter ranges of a certain control mode are met by the pumping parameters of multiple pumping exceeds the first preset number of times according to the monitored pumping parameters of multiple pumping, the atomizing parameters corresponding to the pumping parameter ranges of the control mode are calculated according to the correspondence between the pumping parameter ranges and the atomizing parameters, namely, the corresponding atomizing parameters are calculated by adopting a formula method, so that a pumping curve is formed by fitting. Alternatively, a plurality of preset corresponding relationship curves of the pumping parameter ranges and the atomization parameters are stored in the atomizer 100 in advance, and the corresponding relationship curve, that is, the pumping curve is directly selected according to the pumping parameter ranges of the control mode. It can be appreciated that, because the processor 210 of the electronic atomization device 300 generally has limited computing power, a corresponding relation curve of a plurality of preset pumping parameter ranges and atomization parameters is stored in advance, and a matching curve is selected according to the pumping parameter ranges in practical use, so that the processor 210 is simple in calculation, and the processing efficiency is improved. The corresponding relation curves of the multiple preset suction parameter ranges and the atomization parameters can be formed in advance through multiple experiments and computer fitting.

When the pumping parameters in response to the multiple pumping satisfy the pumping parameter range in one control mode exceeding the first preset times, the processor 210 enters the control mode, and controls the atomizer 100 to perform atomization work according to the corresponding relationship between the pumping parameter range and the atomization parameters included in the control mode and the corresponding atomization parameters. The suction parameter range and the nebulization parameter can be in a table or a curve.

The nebulizer 100 stores at least one control mode in the present application, where each control mode includes a preset correspondence between a pumping parameter range and a nebulizing parameter. In one embodiment, the pumping parameters include two parameters, namely pumping negative pressure and pumping time, wherein the pumping negative pressure comprises two preset intensity thresholds Pa and Pb, the pumping time comprises one preset time threshold Ta, the pumping negative pressure is divided into three preset intensity threshold ranges according to the two preset intensity thresholds Pa and Pb, 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; dividing the pumping time into two preset time threshold ranges according to the preset time threshold Ta, wherein the two preset time threshold ranges are respectively a first preset time threshold range T < Ta, and a second preset time threshold range T is more than or equal to Ta. The atomizer 100 includes six control modes, namely a first control mode L1, a second control mode L2, and a … … 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 within the first preset intensity threshold range and the suction time is within the first preset time threshold range, that is, the suction parameter range of the first control mode L1 is P < Pa, T < Ta; the pumping parameter range of the second control mode L2 is that the pumping negative pressure is in a first preset intensity threshold range, and the pumping time is in a second preset time threshold range, namely the pumping parameter range of the second control mode L2 is P < Pa, and T is more than or equal to Ta; the pumping parameter range of the third control mode L3 is that pumping negative pressure is in a second preset intensity threshold range, pumping time is in a first preset time threshold range, namely, the pumping parameter range of the third control mode L3 is Pa less than or equal to P < Pb, and T < Ta; … … the pumping parameters of other control modes are analogized and are not described in detail.

The pumping parameters of each control mode range with corresponding atomization parameters, wherein the atomization parameters comprise the liquid supply rate of the spraying component 13, the liquid supply amount of the spraying 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 first atomization parameters, the first atomization parameters include a first liquid supply rate V1, a first liquid supply amount M1, and a first atomization power W1, the atomizer 100 is controlled to operate at the first liquid supply rate V1, the first liquid supply amount M1, and the first atomization power W1 in the first control mode L1, and the atomizer 100 is controlled to operate at a sixth liquid supply rate V6, a sixth liquid supply amount M6, and a sixth atomization power W6 in the sixth control mode L6.

The obtained pumping parameters of the multiple pumping of the user can be compared with the pumping parameter ranges of the six control modes, so that the pumping habit of the user can be analyzed and judged, and the atomizer 100 is 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 multiple times of suction of the user satisfy that the suction negative pressure is within the range Pa less than or equal to P < Pb, and the number of times of suction time is within the range T < Ta exceeds five, so that the atomizer 100 enters the third control mode L3, and the atomizer 100 is controlled to atomize at the third atomization parameter, that is, the third liquid supply rate V3, the third liquid supply amount M3 and the third atomization power W3.

It will be appreciated that in other embodiments, the number of control modes of the nebulizer 100 may be set to other numbers, for example, the nebulizer 100 may store two, three, four, or five control modes, each having different pumping parameter ranges, compare the acquired pumping parameters of multiple pumping by the user with the pumping parameter ranges preset by the multiple control modes, and enter a control mode if the number of times that the pumping parameters of multiple pumping satisfy the pumping parameter ranges of a certain control mode of the multiple control modes exceeds the first preset number of times, and control the nebulizer 100 to operate according to the pumping parameters of the control mode.

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

and in response to the pumping parameter at pumping not meeting the control mode, exiting the control mode when the pumping parameter range of the control mode exceeds a second preset number of times.

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

Comparing the obtained suction parameters of the multiple user suction with the suction parameter range of the control mode in which the user suction is located, wherein the suction parameters of the multiple user suction do not meet the requirement that when the suction parameter range of the control mode exceeds the second preset times, the atomizer 100 exits the control mode, namely when the obtained times that the suction parameters of the multiple user suction are not in the suction parameter range of the control mode exceeds the second preset times, the atomizer exits the control mode.

The suction parameter of the multiple suction does not satisfy the suction parameter range of the control mode in which the suction parameter of the multiple suction exceeds the second preset times, and the suction parameter of the continuous multiple suction does not satisfy the suction parameter range of the control mode and exceeds the second preset times, for example, the second preset times are two times, and the suction parameter of the continuous three suction does not satisfy the suction parameter range of the control mode, namely, the suction parameter of the multiple suction does not satisfy the suction parameter range of the control mode in which the suction parameter of the multiple suction exceeds the second preset times, and the control mode is exited; alternatively, the suction parameter exceeding the second preset number of times among the suction parameters of the multiple suction ranges may not satisfy the suction parameter range of the control mode in which the suction parameter exceeds the second preset number of times, for example, the second preset number of times is three, and the suction parameter exceeding the third number of times among the suction parameters of the ten times does not satisfy the suction parameter range of the control mode in which the suction parameter exceeds the third number of times, that is, the suction parameter exceeding the second preset number of times among the suction parameters of the multiple suction does not satisfy the suction parameter range of the control mode in which the suction parameter exceeds the third number of times, and the control mode is exited; the design can be performed according to specific needs, and the second preset times can also be preset according to experience.

In one embodiment, the step of controlling the atomizing parameter of the atomizer 100 according to the suction parameter in step S2 includes:

s21: and in the suction negative pressure rising stage of the user, responding to the fact that the difference DeltaP of the suction negative pressure rising of the user in the second preset time is larger than the first negative pressure threshold value Ps, and controlling the atomizer to stop atomization.

Specifically, the suction negative pressure is obtained once at regular intervals in the whole process of one suction action of the user, and when the difference Δp of the suction negative pressure rise of the user in the second preset time is greater than the first negative pressure threshold value Ps, the atomizer 100 is directly controlled to stop the atomization work in the stage of the suction negative pressure rise of the user, that is, the stage of the suction negative pressure rise of the last time is greater than the suction negative pressure of the previous time. That is, as long as the suction negative pressure of the user is in the rising stage during the suction action of the user, the difference Δp of the suction negative pressure rising of the user is greater than the first negative pressure threshold Ps within any second preset time, it can be determined that the user stops the suction action, and the atomizer 100 is directly controlled to stop the atomization work in advance, which is advantageous for saving energy. Wherein, the controller 240 controls the atomizer 100 to stop atomizing, the injection assembly control unit 241 of the controller 240 controls the injection assembly 13 to stop supplying liquid to the atomizing core 12, and the heating control unit 243 of the controller 240 controls the atomizing core 12 to stop heating and atomizing in advance, which is beneficial to saving energy. For example, the second preset time is 0.3 seconds, the first negative pressure threshold Ps is 800 pa, and the difference Δp of the suction negative pressure rise in any one of the 0.3 second periods during the suction negative pressure rise period of the user is greater than 800 pa, that is, the atomizer 100 is controlled to stop atomizing at the last time point of the 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, and the processor 210 obtains suction negative pressures monitored at a plurality of time points from the airflow sensor 250, and fits the suction negative pressures to the corresponding time points to obtain a negative pressure-time curve as shown in fig. 6. Each time the user performs a pumping action, the pumping negative pressure basically takes a state of descending and then ascending. In the prior art, when a user performs a suction action, the suction negative pressure of stopping suction of the user is set as a fixed negative pressure threshold value, whether the user stops the suction action is judged according to the suction stopping negative pressure threshold value, when the suction negative pressure of the user reaches the suction stopping negative pressure threshold value, the user is indicated to stop the suction action, and then the atomizer is controlled to stop atomization. For example, as shown in fig. 6, the start negative pressure of the atomizer 100 is-300 pa, the stop suction negative pressure threshold is-300 pa, and the atomizer 100 can be controlled to stop atomization only when the suction negative pressure of the user reaches-300 pa again, that is, atomization can be stopped at the nineteenth time point D3 in fig. 8.

In the control method of the atomizer 100 provided in this embodiment, when the difference Δp of the suction negative pressure rise of the user in the second preset time is monitored to be 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 atomizer 100 is controlled to stop atomization. As shown in fig. 6, in the suction negative pressure rising period of the user, the second preset time is 0.1 seconds, and in 0.1 seconds, the difference Δp of the suction negative pressure rising at the seventeenth time point D2 and the sixteenth time point D1 is greater than the first negative pressure threshold value Ps, and the nebulizer 100 is immediately controlled to stop nebulization at the seventeenth time point D2, which is the last time point of the second preset time. As can be seen from fig. 6, by using the control method of the atomizer 100 provided by the present application to control the atomizer 100, the time point when the atomizer 100 stops atomizing is earlier than the time point when the atomizer stops atomizing in the prior art, so that the atomizer 100 can be controlled to stop atomizing in advance, and energy is saved.

The negative pressure-time curve is typically the same for the same user, while the negative pressure-time curves for different users are typically different. Compared with the prior art that whether the user stops pumping action is judged by stopping the pumping negative pressure threshold value, the method for judging whether the user stops pumping action or not is more intelligent by the magnitude relation between the difference value delta P of the pumping negative pressure rise of the user in the second preset time and the first negative pressure threshold value Ps, can be more suitable for different user groups, adaptively controls different user groups, and improves the performance of the atomizer 100.

Referring to fig. 7, in an embodiment, the step of controlling the atomization parameter of the atomizer 100 according to the suction parameter in step S2 includes the following steps:

s22: recording the suction negative pressure of the user corresponding to the last time point of the second preset time as a second negative pressure threshold value.

Specifically, according to the last time point of the second preset time when the difference Δp of the suction negative pressure rise of the user in step S21 is greater than the first negative pressure threshold Ps, the suction negative pressure corresponding to the time point is recorded as the second negative pressure threshold. As shown in fig. 6, the suction negative pressure (for example, negative 1100 pa) corresponding to the seventeenth time point D2, which is the last time point of the second preset time, is recorded as the second negative pressure threshold value.

S23: and controlling the atomizer to stop atomization in response to the suction negative pressure of the subsequent user being greater than the second negative pressure threshold.

Specifically, during the suction action of the subsequent user, the magnitudes of the suction negative pressure of the user and the second negative pressure threshold are determined according to the suction negative pressure obtained at regular intervals, when the suction negative pressure of the user is greater than the second negative pressure threshold, the user is indicated to stop the suction action, and the controller 240 immediately controls the atomizer 100 to stop atomization, so that energy conservation is facilitated.

It can be understood that in this embodiment, the suction negative pressure of the user corresponding to the last time point of the second preset time is taken as the second negative pressure threshold, the second negative pressure threshold is directly adopted as the basis for judging whether the user stops the suction action, so as to judge when the atomizer stops atomizing, and compared with whether the difference Δp of the suction negative pressure rise of the user in each suction action is greater than the first negative pressure threshold Ps in the second preset time, the judgment process is simpler and the efficiency is higher.

In another embodiment, the step of acquiring the user' S aspiration parameters in step S1 includes:

and acquiring the suction negative pressure of the user at regular intervals.

Specifically, when the user performs the suction operation, the airflow sensor 250 monitors the suction negative pressure of the user at regular intervals throughout the duration of one suction operation, and monitors the suction negative pressure of the user multiple times throughout the duration of one suction operation, that is, monitors the suction negative pressure of the user at multiple time points, and the processor 210 acquires the suction negative pressures monitored at multiple time points from the airflow sensor 250. For example, the user's suction negative pressure may be monitored every 0.1 seconds throughout a user's suction action, and the processor 210 obtains suction negative pressures at a plurality of time points monitored every 0.1 seconds throughout a user's suction action.

Referring to fig. 8, the step of controlling the atomizing parameter of the atomizer 100 according to the suction parameter described in step S2 includes:

s21b: a negative pressure-time curve is generated from the suction negative pressure and the corresponding point in time.

Specifically, according to the suction negative pressure monitored at regular intervals in the whole process of one suction action of the user, the suction negative pressures of a plurality of time points in the whole process of one suction action of the user are obtained, a negative pressure-time curve is generated by fitting according to the obtained suction negative pressures of a plurality of corresponding time points, the vertical axis of the negative pressure-time curve represents the suction negative pressure, and the horizontal axis represents the corresponding time point.

S22b: the slope of the negative pressure-time curve is obtained.

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

S23b: in response to the slope being greater than the slope threshold, the nebulizer is controlled to stop nebulization.

Specifically, according to the obtained slope of the curve, the magnitude of the obtained slope and the slope threshold is determined, and 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 embodiment, the atomizer 100 may be controlled to stop the atomization operation according to the fact that the slope between some two adjacent points in the negative pressure-time curve is greater than the slope threshold; the nebulizer 100 may be controlled to stop the nebulization according to four continuous time points in the whole negative pressure-time curve, i.e. when the slopes of three continuous time periods are all greater than the slope threshold, so as to avoid misjudging that the suction is stopped due to a sudden change of the slope caused by ventilation or cough of the user. Wherein, the spraying component control unit 241 of the controller 240 controls the spraying component 13 to stop supplying liquid to the atomizing core 12, and the heating control unit 243 of the controller 240 controls the atomizing core 12 to stop heating and atomizing, which is beneficial to saving energy. The slope of the negative pressure-time curve in this embodiment being greater than the slope threshold is the same as the meaning that the difference Δp of suction negative pressure rise in the second preset time in the above embodiment is greater than the first negative pressure threshold Ps, which indicates that the user suction negative pressure is suddenly changed.

It will be appreciated that even the same user may draw in different ways, i.e. with different negative pressure-time curves. Therefore, it is more accurate to judge that the user stops sucking than to set the second negative pressure threshold value described above.
