[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1 As shown, Figure 1 This is a method flow chart of a control method of an electronic atomizer provided by an embodiment of the present invention. The control method of the electronic atomizer comprises the following steps:

[0049] 101. When it is detected that a target person exists within a first contamination range of the electronic atomizer, a current position of the target person is determined.

[0050] In an embodiment of the present invention, a heating wire and an electronic liquid are provided in the electronic atomizer. The electronic atomizer heats the electronic liquid through the heating wire to generate smoke. The electronic atomizer may be an electronic filter of an electronic cigarette or a cigarette, etc. The above-mentioned point recommendation can be understood as a user recommending a location so that when the user arrives at the location to use the electronic atomizer, the impact of using the electronic atomizer on the surrounding people can be reduced. The control method of the above-mentioned electronic atomizer can be implemented by a processor of the electronic atomizer. Specifically, the processor controls the heating wire to heat with a set heating power, so that the electronic liquid is heated and evaporates a certain amount of smoke, which will diffuse into the surrounding environment to form a pollution area. Different amounts of smoke correspond to different diffusion ranges, that is, different amounts of smoke correspond to different sizes of pollution areas. Generally speaking, the larger the amount of smoke, the larger the corresponding pollution area.

[0051] The first pollution range can be a range where the smoke concentration is greater than the reference value of the concentration safety index, and the PM2.5 concentration safety index is >75ug / m 3 The first pollution range is obtained according to the ion diffusion theory equation. In the first pollution range, the PM2.5 concentration safety index is >75ug / m 3 Outside the first pollution range, the PM2.5 concentration safety index is <75ug / m 3 . The ion diffusion theory equation is a mathematical model that describes the diffusion of substances in space, and takes into account the initial concentration of smoke, the diffusion coefficient, and the influence of environmental factors on the diffusion of smoke. In a possible embodiment, the above-mentioned PM2.5 concentration safety index reference value is not specifically limited, and the PM2.5 concentration safety index can also be other acceptable concentration values, such as the concentration value after the smoke concentration exhaled by the user is reduced by 1 / 2 or 2 / 3, which can actually reduce the original secondhand smoke hazard.

[0052] An infrared sensor may be provided in the electronic atomizer. The infrared sensor is used to detect the human body in the current environment, and use the infrared echo to detect whether there is a target person in the current environment. The infrared echo distance can be used to measure the distance between the electronic atomizer and the human body, and the person whose distance is less than the distance from the electronic atomizer to the boundary of the first pollution range is determined as the target person. If the infrared sensor does not detect the target person, the control method of the electronic atomizer in this embodiment is not executed. When the electronic atomizer senses that the position of the surrounding people is outside the first pollution range corresponding to the last power, the power of the heating wire of the electronic atomizer is not adjusted, and the heating power used by the user when smoking last time is still maintained. The above-mentioned target person can be a specific target group, such as pregnant women, children, the elderly and the like, and the specific target group can be identified by infrared scanning imaging, sound recognition and the like.

[0053] When a target person is detected within the first pollution range of the electronic atomizer, the current position of the target person is determined, and the current position of the target person can be used to determine the boundary of the first pollution range. If there are multiple target persons, the distance between each target person and the electronic atomizer is determined, and the current position of the target person with the smallest distance is used to determine the boundary of the first pollution range.

[0054] In a possible embodiment, when the number of target persons within the first pollution range reaches a preset number, the current position of the target person is determined and the control method of the electronic atomizer in this embodiment is executed.

[0055] 102. Determine the second pollution range of the electronic atomizer with the electronic atomizer as the center and the current position as the boundary.

[0056] In the embodiment of the present invention, since there is a target person within the first pollution range, if the user uses the electronic atomizer, the smoke generated by the electronic atomizer will be inhaled by the target person, which will greatly affect the health of the target person. Therefore, it is necessary to control the smoke pollution range of the electronic atomizer so that the next time the user uses the electronic atomizer, the smoke pollution range of the electronic atomizer (PM2.5 concentration safety index>75ug / m 3 The range of the smoke is reduced, thereby reducing the impact of smoke on the target personnel.

[0057] A smaller smoke diffusion range is defined with the electronic atomizer as the center and the current location of the target person as the boundary. This smaller smoke diffusion range can be determined as the second pollution range. There is no target person in the second pollution range, and the second pollution range is smaller than the first pollution range. It should be noted that the second pollution range is also greater than the reference value of the smoke concentration safety index, such as PM2.5 concentration safety index>75ug / m 3Within the second pollution range, the PM2.5 concentration safety index is >75ug / m 3 Outside the second pollution range, the PM2.5 concentration safety index is <75ug / m 3 In a possible embodiment, the PM2.5 concentration safety index reference value is not specifically limited, and the PM2.5 concentration safety index may also be other acceptable concentration values, such as the concentration value after the smoke concentration exhaled by the user is reduced by 1 / 2 or 2 / 3, which can actually reduce the original secondhand smoke hazard.

[0058] In a possible embodiment, the size and shape of the boundary of the second pollution range can be dynamically adjusted according to the current position of the target person and the boundary of the first pollution range through geometric calculation or algorithm optimization until the current position of the target person is on or outside the boundary of the second pollution range.

[0059] 103. According to the corresponding relationship between the smoke concentration exhaled by the user and the heating power, determine the next heating power of the heating wire under the second pollution range condition.

[0060] In the embodiment of the present invention, the corresponding relationship between the concentration of smoke exhaled by the user and the heating power can be expressed by a mapping table or a mathematical model.

[0061] In the mapping table, there is a one-to-one correspondence between smoke concentration and heating power. When the smoke concentration is known, the corresponding heating power can be found through the mapping table. When the heating power is known, the corresponding smoke concentration can also be found through the mapping table.

[0062] In the mathematical model, the smoke concentration can be input into the mathematical model, and the corresponding heating power can be calculated by the mathematical model, or the heating power can be input into the mathematical model, and the smoke concentration can be calculated by the mathematical model.

[0063] It should be noted that the above-mentioned smoke concentration is the smoke concentration exhaled by the user. The smoke concentration exhaled by the user is absorbed by the user's body, and the content of other harmful substances is lower than the content of harmful substances in the smoke generated by the electronic atomizer.

[0064] The smoke exhaled by the user diffuses to form a pollution range. Different amounts of smoke correspond to different diffusion ranges, that is, different amounts of smoke correspond to different pollution areas. Generally speaking, the larger the amount of smoke, the larger the corresponding pollution area. When the second pollution range is determined, the ion diffusion theory equation can be used to reversely infer the concentration of smoke exhaled by the user corresponding to the second pollution range.

[0065] 104. When the electric heating wire is heated for the next time, the electric heating wire is controlled to heat the electronic liquid by the next heating power.

[0066] In the embodiment of the present invention, the next heating of the heating wire indicates that the user is taking the next puff. At this time, the processor can control the heating wire to heat with the next heating power, thereby heating the electronic liquid, evaporating the electronic liquid to produce a corresponding amount of smoke, and the smoke is absorbed and exhaled by the user's body, diffused to form a real second pollution range, and the target person is outside the second pollution range. Therefore, there is no target person in the second pollution range, and the impact on the surrounding people can be minimized.

[0067] The next heating power is used to control the heating wire to heat the electronic liquid, thereby reducing the amount of smoke generated by the electronic atomizer, thereby reducing the concentration of smoke exhaled by the user, thereby reducing the concentration of secondhand smoke reaching the target person's position, or obtaining a safe concentration at the target person's position (the safe concentration is not necessarily 0, it can be PM2.5 less than 75ug / m 3 concentration, halved concentration or other safer concentrations, such as the concentration of smoke exhaled by the user reduced by 1 / 2 or 2 / 3, as long as the original harm of secondhand smoke can be reduced).

[0068] In an embodiment of the present invention, when it is detected that there is a target person within the first pollution range of the electronic atomizer, the current position of the target person is determined, and the first pollution range is obtained according to the ion diffusion theory equation; with the electronic atomizer as the center and the current position as the boundary, the second pollution range of the electronic atomizer is determined, and there is no target person within the second pollution range, and the second pollution range is smaller than the first pollution range; according to the correspondence between the smoke concentration exhaled by the user and the heating power, the next heating power of the heating wire under the condition of the second pollution range is determined; when the heating wire is heated for the next time, the heating wire is controlled by the next heating power to heat the electronic liquid. The present invention can sense the distance between the surrounding people and the electronic atomizer, and adjust the heating power of the heating wire in the electronic atomizer according to the distance between the electronic atomizer and the surrounding people, thereby reducing the atomized steam of the electronic atomizer and reducing the pollution area of ​​the secondhand smoke concentration, so as to ensure that the surrounding people are always outside the pollution area of ​​the electronic atomizer smoke, and reduce the health impact of secondhand smoke on the surrounding people.

[0069] It should be noted that the control method of the electronic atomizer provided in the embodiment of the present invention can be applied to devices such as electronic atomizers, smart phones, tablets, computers, servers, etc. that can perform the control method of the electronic atomizer.

[0070] It is understandable that in the specific implementation of this application, user data, personnel data, device data and other related data are involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data, as well as model training, deployment and use, must comply with relevant laws, regulations and standards of relevant countries and regions.

[0071] Optionally, when a target person is detected to be within the first pollution range of the electronic atomizer, before the step of determining the current position of the target person, the last heating power of the heating wire and the correspondence between the smoke concentration exhaled by the user and the heating power can be obtained; based on the correspondence between the smoke concentration exhaled by the user and the heating power, the first smoke concentration exhaled by the user under the condition of the last heating power is determined; using the ion diffusion theory equation, the smoke diffusion range corresponding to the first smoke concentration is determined; based on the preset critical pollution concentration, the first pollution range of the electronic atomizer is determined within the smoke diffusion range.

[0072] In an embodiment of the present invention, each time the electric heating wire is heated, the corresponding heating power can be stored in the memory. After the electric heating wire is heated, the control method of the electronic atomizer is executed at a preset time interval to determine the corresponding heating power for the next heating. The preset time interval can be determined according to the user's smoking habits. For example, the user's smoking frequency can be obtained, and the preset time interval between two smokings can be determined according to the user's smoking frequency. Of course, the time interval between two smokings corresponding to a similar time point on the previous day can also be referred to.

[0073] The corresponding relationship between the smoke concentration exhaled by the user and the heating power is obtained through experimental measurement. The smoke concentration exhaled by the user can be measured at different heating powers, and the data points of these smoke concentrations can be recorded. Then, a curve or formula describing the relationship between the smoke concentration and the heating power can be fitted using data analysis methods, such as regression analysis.

[0074] Specifically, the correspondence between the smoke concentration exhaled by the user and the heating power can be expressed through a mapping table or a mathematical model. In the mapping table, there is a one-to-one correspondence between smoke concentration and heating power. When the smoke concentration is known, the corresponding heating power can be found through the mapping table. When the heating power is known, the corresponding smoke concentration can also be found through the mapping table. In the mathematical model, the smoke concentration can be input into the mathematical model, and the corresponding heating power can be calculated by the mathematical model. The heating power can also be input into the mathematical model, and the smoke concentration can be calculated by the mathematical model.

[0075] Based on the correspondence between the smoke concentration exhaled by the user and the heating power, and the last heating power of the heating wire obtained, the smoke concentration exhaled by the user during the last smoking, ie, the first smoke concentration exhaled by the user, can be calculated.

[0076] It should be noted that the electronic liquid of the electronic atomizer contains substances such as nicotine. The built-in battery of the electronic atomizer provides electricity to atomize the electronic liquid, and the liquid electronic liquid evaporates into gaseous smoke. When the user uses the electronic atomizer, steam is provided to the user according to the negative pressure signal detected by the electronic atomizer sensor. The haze produced by the electronic atomizer contains many harmful substances. The particles in the haze will cause the PM2.5 value in the air to change. At the same time, the excessive PM2.5 index will affect human health. The current PM2.5 value in the air is detected as PM 1 When the user uses the electronic atomizer at the default power, when the straight-line distance from the user's electronic atomizer is d 1 When C1+PM 1 =PM 2 >S(safe concentration, such as 75ug / m 3 ), with the electronic atomizer as the center and the radius as d 1 The circle is considered to be the electronic atomizer secondhand smoke pollution area (i.e., the first pollution range), and according to different powers, the smoke concentration will produce a radius value in the interval [0,d max ] circle. When other people enter the smoke pollution area of ​​the electronic atomizer, the electronic atomizer power is adjusted. The electronic atomizer determines the smoke concentration C2 allowed to be exhaled by the user at the current distance based on the sensed human body distance (to ensure that the concentration of other people's position C1 does not exceed the standard), as well as the heating power P of the electronic atomizer that forms the smoke concentration C2. When the user uses the electronic atomizer next time, the electronic atomizer power is adjusted in time to reduce the smoke concentration of the electronic atomizer next time (next puff), thereby reducing the electronic atomizer secondhand smoke pollution area (i.e., the second pollution range) and protecting the health and safety of others.

[0077] The above ion diffusion theory equation is shown in the following formula (1.1):

[0078]

[0079] Among them: J represents the diffusion flux, that is, the diffusion rate; D represents the diffusion coefficient, which is an inherent property (fixed value). The larger the diffusion coefficient, the faster the diffusion; C represents the concentration, where C is a function of the distance x. 1 =PM 2 >S, the distance x is calculated, and then the first contamination range of the electronic atomizer is determined.

[0080] Optionally, in the step of obtaining the correspondence between the concentration of smoke exhaled by the user and the heating power, the first mass of smoke generated by the electronic atomizer under the heating condition of the reference heating power can be determined according to the energy formula for converting the electronic liquid from liquid to gas; based on the first mass, the second mass of the smoke exhaled by the user can be determined according to the preset human absorption coefficient; based on the second mass, the smoke concentration per unit volume can be determined according to the gas mass-volume relationship to obtain the reference smoke concentration of the smoke exhaled by the user; based on the correspondence between the reference heating power and the reference smoke concentration, the correspondence between the concentration of smoke exhaled by the user and the heating power can be determined.

[0081] In an embodiment of the present invention, it is considered that part of the harmful substances in the smoke generated by the electronic atomizer will be absorbed by the user's body, so that the concentration of harmful substances in the smoke exhaled by the user is reduced. Therefore, the smoke generated by the electronic atomizer corresponding to the smoke exhaled by the user can be determined based on the conversion relationship between the smoke generated by the electronic atomizer and the smoke exhaled by the user, or the smoke generated by the electronic atomizer and the corresponding smoke exhaled by the user can be determined.

[0082] It should be noted that the smoke generated by the electronic atomizer is determined by the heating power and heating time. To generate a certain amount of smoke, a certain amount of heat energy is required. Different heat energies will produce different amounts of smoke. The amount of smoke is represented by the first substance mass. The first substance mass can be the content of harmful substances, the content of particles constituting the smoke, or PM2.5>75ug / m 3 of particle content.

[0083] The energy formula may be a formula based on Joule's law. According to the energy formula for converting the electronic liquid from liquid to gas, the first mass of smoke generated by a unit mass of the electronic liquid after being heated under the heating condition of the reference heating power is determined.

[0084] Since the smoke is not completely exhaled after inhalation by the user, part of the smoke will be absorbed by the human body, so the human body absorption coefficient is considered to correct the amount of smoke actually exhaled by the user, thereby obtaining the second substance amount of the smoke exhaled by the user. The human body absorption coefficient can be an empirical value, and this embodiment does not limit the method for obtaining the human body absorption coefficient.

[0085] Furthermore, consider that the smoke from the electronic atomizer is inhaled and then exhaled by the human body. Taking tobacco as an example, N% of the harmful substances will be absorbed by the human body, and the remaining (100-N)% of the substances will be exhaled from the human body. At this time, the mass of the exhaled gas (the second mass) is M 1 The default value is the mass of substance before human body absorption (first mass of substance) M 2(100-N)%, and the atomization of the electronic liquid in the electronic atomizer is a physical process. The atomizer heats the electronic liquid to the evaporation temperature, senses the negative pressure signal through the atomizer sensor, and delivers the atomized electronic atomizer haze to the user. According to the principle of thermodynamics, it can be inferred that when the user exhales the electronic atomizer, the concentration of secondhand smoke is C 2 The heating power of the electronic atomizer.

[0086] According to the gas mass volume relationship, based on the amount of the second substance, the smoke concentration per unit volume is determined to obtain the reference smoke concentration of the smoke exhaled by the user. The above gas mass volume relationship can be expressed as follows:

[0087] M 1 =V 单 ×C 2 (2.1)

[0088] Where: V 单 Represents the unit volume, which is 1m 3 ; C 2 It represents the reference smoke concentration exhaled by the user. The reference smoke concentration C 2 is the smoke density per unit volume. M 1 is the mass of substance before human body absorption (first mass of substance) M 2 (100-N)%". That is:

[0089] M 1 =M 2 ×(100-N)%(2.2)

[0090] Considering that the atomization of electronic liquid is a physical process, the electronic liquid of the electronic atomizer is evaporated after M 2 =M 3 (Electronic liquid quality), that is:

[0091] M 1 =M 3 ×(100-N)%(2.3)

[0092] Among them, the mass of electronic liquid M 3 It can be monitored with a liquid level sensor.

[0093] After obtaining the reference smoke concentration C 2 After that, the reference smoke concentration C can be constructed 2 The smoke concentration C produced by the electronic atomizer 3 The mapping relationship between them, under the condition of fixed heating time, the smoke concentration C generated by the electronic atomizer is inferred according to the energy formula 3 The energy required, and then the reference smoke concentration C 2The required reference heating power P is used to construct the smoke concentration C exhaled by the user through multiple test tests. 2 The corresponding relationship between the heating power P and the different smoke concentrations C 2 The numerical correspondence between the corresponding heating power P is written into the mapping table, and different smoke concentrations C can also be calculated. 2 Mathematical model between and corresponding heating power P.

[0094] Optionally, in the step of determining the first mass of smoke generated by the electronic atomizer under heating conditions of a reference heating power according to an energy formula for converting the electronic liquid from liquid to gas, the average heating time of the heating wire and the reference temperature for converting the electronic liquid from liquid to gas can be determined; based on the average heating time and the reference heating power, the reference electric energy for converting the electronic liquid from liquid to gas is determined; based on the electrothermal conversion efficiency, the reference thermal energy corresponding to the reference electric energy is determined; based on the specific heat capacity of the electronic liquid, the reference thermal energy and the reference temperature, the first mass of smoke generated by the electronic atomizer is determined.

[0095] In the embodiment of the present invention, it should be noted that the working principle of the electronic atomizer mainly relies on the heating of the electronic liquid by the heating wire to convert it from liquid to gas, thereby forming smoke that can be inhaled by the user, which mainly involves the principles of thermodynamics, phase change from liquid to gas, and conservation of matter, etc.

[0096] The above reference temperature is the temperature threshold required to convert the electronic liquid from liquid to gas. Generally speaking, the reference temperature can be set to a temperature slightly higher than the boiling point of the electronic liquid to ensure that the electronic liquid can be fully atomized. Heating the electronic liquid to the reference temperature can make the electronic liquid atomized and produce smoke.

[0097] The average heating time of the above-mentioned heating wire depends on the user's setting or the user's smoking habits.

[0098] After determining the average heating time of the heating wire and the reference temperature, calculate the reference electrical energy required to convert the electronic liquid from liquid to gas. Based on the principle of electrothermal conversion, that is, electrical energy is converted into thermal energy, which in turn heats the electronic liquid. It can be obtained by multiplying the heating power of the heating wire by the average heating time.

[0099] Next, the reference electrical energy is converted into reference thermal energy according to the electrothermal conversion efficiency. 3 , the mass of the electronic liquid M 3 The energy required to convert from liquid to gas is given by the following equation:

[0100] Q 1 =M 3 ×C 热 ×(T 2 -T1 ) (2.4)

[0101] Where: Q 1 It represents the mass of the electronic liquid M 3 Reference heat energy required for atomization, C 热 represents the specific heat capacity of the electronic liquid; T 2 represents the temperature at which the electronic liquid evaporates (reference temperature); T 1 It represents the temperature of the electronic liquid under normal conditions.

[0102] The energy required for the atomization of the electronic liquid is provided by the heating wire of the electronic atomizer battery, where the electrothermal conversion efficiency is η%, then:

[0103] Q 1 =η%Q 2 (2.5)

[0104] Where: Q 2 It represents the reference electrical energy provided by the electronic atomizer battery.

[0105] The reference thermal energy of the heating wire of the electronic atomizer battery can be calculated as follows:

[0106]

[0107] Where: P represents the heating power of the heating wire, t 均 It represents the average usage time (average heating time) of the user's electronic atomizer within the T time period, R represents the resistance of the heating wire, U represents the voltage of the electronic atomizer, and Q 2 Substituting back into formula (2.5), we have:

[0108]

[0109] Considering that the internal sensor of the electronic atomizer determines whether the user inhales the electronic atomizer according to the change of air pressure, the power heating is realized based on the inhalation action to realize the smoke discharge operation of the electronic atomizer. In the T time period, the average time of the user using the electronic atomizer n times is:

[0110]

[0111] By combining formulas (2.1), (2.3), (2.6), (2.8) and (2.9), we can deduce the smoke concentration C exhaled by the user: 2 The relationship between the heating wire power P is shown in the following formula:

[0112]

[0113] From formula (2.10), we can see that the above C 热 , T 2 , T 1 , V 单 , N,η,t 均 is known or available, therefore, when the heating wire power P is known, the smoke concentration C exhaled by the user can be calculated 2 , when the heating wire power P is known, the smoke concentration C exhaled by the user can also be calculated 2 .

[0114] Optionally, in the step of determining the smoke diffusion range corresponding to the first smoke concentration using the ion diffusion theory equation, the functional relationship between the smoke concentration and the diffusion distance can be determined based on the ion diffusion theory equation; based on the functional relationship between the smoke concentration and the diffusion distance, the smoke diffusion range corresponding to the first smoke concentration can be determined.

[0115] In the embodiment of the present invention, based on the ion diffusion theory equation (1.1), for x=d 1 The target object, the smoke diffusion range is [0, ∞]. After integrating equation (1.1), the functional relationship between smoke concentration and diffusion distance can be deduced as follows:

[0116]

[0117] When x=0, C(0) represents the starting concentration C2 at the starting point, that is, the smoke concentration exhaled by the user, and x represents the distance between the ion in the medium and the electronic atomizer. At this time, it represents the distance between the ion in the air and the electronic atomizer. According to formula (1.2), it can be deduced that:

[0118]

[0119] It can be understood that, from formula (1.3), the constant α is the concentration of smoke exhaled by the user. If the actual distance of the current target person is x=d 1 When x=d 1 When the concentration C1 at the location of the target person does not exceed S (S is greater than 75ug / m 3 is regarded as the critical concentration of pollution), that is, the maximum value of C1 is C1=C(d 1 )=75, then "x=d 1 , C1=C(d 1 )=S” into formula (1.2), we can find the constant α.

[0120] Furthermore, the smoke diffusion range is [0, ∞]. When the first smoke concentration exhaled by the user is known (the starting concentration C2), and the maximum value of C1 is C1=C(d)=S, by substituting it into formula (1.2), the distance d between the electronic atomizer and the boundary of the pollution range can be calculated, and then the first pollution range of the electronic atomizer can be determined according to the distance d between the electronic atomizer and the boundary of the pollution range.

[0121] Optionally, in the step of determining the next heating power of the heating wire under the conditions of the second pollution range based on the correspondence between the smoke concentration exhaled by the user and the heating power, the second smoke concentration exhaled by the user under the conditions of the second pollution range is determined using the ion diffusion theory equation; based on the correspondence between the smoke concentration exhaled by the user and the heating power, the target heating power corresponding to the second smoke concentration is determined; based on the target heating power, the next heating power of the heating wire is determined.

[0122] In the embodiment of the present invention, when the distance x between the electronic atomizer and the boundary of the second pollution range is known, the second smoke concentration (initial concentration C2) exhaled by the user can be calculated by substituting it into formula (1.2).

[0123] After determining the second smoke concentration, the next heating power P of the heating wire can be calculated based on the above formula (2.10). 实 .

[0124] In a possible embodiment, the corresponding next heating power P can also be directly found by looking up the mapping table. 实 .

[0125] Optionally, in the step of determining the next heating power of the heating wire based on the target heating power, the heating power adjustment mode of the heating wire can be determined, and the heating power adjustment mode of the heating wire is a stepless adjustment mode or a gear adjustment mode; if the heating power adjustment mode is the stepless adjustment mode, the target heating power is directly determined as the next heating power of the heating wire; if the heating power adjustment mode is the gear adjustment mode, then among all power gears whose heating power is less than the target heating power, the largest power gear is determined as the target power gear, and the heating power corresponding to the target power gear is determined as the next heating power of the heating wire.

[0126] In the embodiment of the present invention, in the stepless adjustment mode, the power adjustment of the heating wire is smooth adjustment. In the gear adjustment mode, there are multiple power gears, each power gear has a corresponding heating power, and in the gear adjustment mode, the power adjustment of the heating wire is gear adjustment.

[0127] When the heating wire power belongs to the gear adjustment mode, such as: when P is calculated 实Afterwards, if the current machine adjustable gear is: P 1 <P 实 <P 2 (P 2 The power before adjustment); the heating wire power P 实 Will automatically adjust to P 1 , further reduce the power of the heating wire and reduce the pollution area of ​​the electronic atomizer secondhand smoke concentration

[0128] When the heating wire power is adjusted in stepless adjustment mode, it is automatically adjusted to P obtained by formula (2.10) 实 .
