[0002] The electronic atomizer is provided with an atomizing core for heating the atomized oil, and a heating wire is usually provided on the atomizing core. In the prior art, a single heating wire is often used for continuous heating. Since the single heating wire will gradually age or be attached with impurities during continuous use, the smoke concentration of the aged or impurity-attached heating wire will decrease, which will eventually affect the atomization quality and taste of the oil.

[0003] Therefore, there is an urgent need for a dual heating wire control method that can ensure the stability of atomization quality and increase the service life of the heating wire. Summary of the invention

[0050] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0052] Electronic atomizers usually include an oil tank and an atomizer core. The oil tank is a well-sealed containing chamber that can directly contain liquid oil or store oil by setting a porous body for storing oil in the oil tank. The atomizer core is usually configured as a cotton core soaked in oil wrapped around the heating wire. The cotton core is in contact with the oil in the oil tank, so that the cotton core is soaked in oil, and finally the oil on the cotton core is heated and atomized by the heating wire. However, if the single heating wire continues to work, after the electronic atomizer has been used for a period of time, the quality of the smoke atomized by the electronic atomizer will decrease due to the uneven oil soaking on the cotton core, the aging of the heating wire, and the attachment of impurities, which will affect the taste.

[0053] To solve the above problems, see Figure 1 In a first aspect, an embodiment of the present invention provides a method for controlling heating of a double heating wire of an electronic atomizer, the method comprising:

[0054] S1: Obtaining the total calorific value and the double heating wire parameters required to atomize all the oil in the oil tank, and obtaining the total atomization time required to atomize all the oil in the oil tank according to the total calorific value and the double heating wire parameters;

[0055] S2: obtaining a preset time threshold according to the smoke concentration generated when the dual heating wires are working and the total atomization time, wherein the preset time threshold is less than the total atomization time;

[0056] S3: Obtain the current working mode of the dual heating wire, compare the actual usage time of the dual heating wire with the preset time threshold, and regulate the heating of the dual heating wire according to the comparison result, wherein the working mode includes a single-shot alternating mode and / or a dual-shot mode.

[0057] In this embodiment, the parameters of the dual heating wire (two heating wires) include resistance, input voltage and resistance change coefficient, wherein the resistance change coefficient is determined based on the material of the heating wire, the cross-sectional diameter of the heating wire and the temperature of the heating wire, and different heating wires correspond to different resistance change coefficients.

[0058] First, determine the oil characteristics, which include the oil's viscosity, composition, and sensitivity to temperature, which will result in different smoke concentrations produced by different oils under the same heating method. At this time, determine the total calorific value required to heat and atomize all the oil in the oil tank based on the oil tank capacity and oil characteristics. The total calorific value and the heating wire parameters can be calculated to obtain the total atomization time, that is, the total time the user can ultimately use the electronic atomizer under ideal conditions.

[0059] Through the simulated suction experiment, the smoke concentration generated by the heating wire is detected in real time, the atomization quality of the smoke is judged by the smoke concentration, and then the critical value of the smoke quality, that is, the smoke concentration, is determined according to the actual suction taste. That is, the smoke concentration above this critical value can ensure the smoke quality and taste; when the smoke concentration is below the critical value, it proves that the heating wire is seriously aged or too many impurities are attached, and it is impossible to continuously produce high-quality smoke. Therefore, when the critical value of the smoke concentration is determined, the suction time when the critical value of the smoke concentration is reached is obtained accordingly, which is set as the preset time threshold. The critical values ​​of smoke concentrations corresponding to heating wires with different parameters are different. In actual use, the user detects the heating time of the dual heating wires and compares it with the preset time threshold and the current working mode of the dual heating wires. The heating mode of the dual heating wires is adjusted by comparing the results, so as to slow down the problem of unstable smoke quality caused by the aging of the heating wires and improve the service life of the electronic atomizer. Among them, the single-shot alternating mode is that the dual heating wires work independently and alternately, and the heating wire has a longer service life in the single-shot alternating mode; the dual-shot mode is that the dual heating wires work together, and the smoke generated in the dual-shot mode is thicker and has a better taste.

[0060] Furthermore, the dual heating wire includes a first heating wire and a second heating wire. When the working mode is the single-shot alternating mode, comparing the actual use time of the dual heating wire with the preset time threshold, and regulating the heating of the dual heating wire according to the comparison result includes:

[0061] S311: obtaining a first heating time and a second heating time when the first heating wire and the second heating wire work alternately, and when the sum of the first heating time and the second heating time is less than the preset time threshold, controlling the first heating wire and the second heating wire to maintain alternating operation;

[0062] S312: When the sum of the first heating time and the second heating time is greater than or equal to the preset time threshold, the first heating wire is controlled to stop working, and the second heating wire is controlled to keep working.

[0063] In this embodiment, if Figure 4, the double heating wire includes a first heating wire and a second heating wire, the first heating wire is arranged at the upper end of the second heating wire and in parallel with the second heating wire, the first heating wire includes a first input end, the second heating wire includes a second input end, and the first heating wire and the second heating wire are connected to an output end; in the single-shot alternating mode, the first heating wire and the second heating wire work alternately and independently, that is, when the first heating wire works, the second heating wire does not work, and the voltage is connected from the first input end and connected from the output end; when the second heating wire works, the first heating wire does not work, and the voltage is connected from the second input end and connected from the output end; setting the single-shot alternating mode can effectively reduce the problem of rapid aging of the heating wire, excessive and concentrated impurities attached to the heating wire caused by the independent work of the single heating wire, and ultimately causing the atomization quality to decrease; the single-shot alternating mode can be used to improve the life and atomization stability of the electronic atomizer and improve the user experience. In the double-shot mode, the first heating wire and the second heating wire work simultaneously, that is, the voltage is input to the first input end and the second input end at the same time and connected from the output end, at this time, the first heating wire and the second heating wire are connected in parallel; the double-shot mode is not limited by the preset time threshold, and the double heating wires work together until the oil is completely atomized and exhausted. When the user starts using the device, he can choose the single-shot alternating mode or the double-shot mode. When the user selects the single-shot alternating mode from the first use to the end of the oil running out, the first heating time actually heated by the first heating wire and the second heating time actually heated by the second heating wire are obtained, and the sum of the first heating time and the second heating time is compared with the preset time threshold. When the preset time threshold is exceeded, only the second heating wire is controlled to work independently.

[0064] The determination of the preset time threshold is closely related to the quality of the smoke. First, due to the continuous consumption of oil and the gravity of the oil, the oil content in the cotton core is less at the top and more at the bottom. Therefore, when the same heat is applied, the smoke concentration generated at the top of the cotton core will be lower than that at the bottom and it is easy to burn. Secondly, due to the repeated use of the heating wire, the heating wire will age or impurities will adhere to the surface of the heating wire, which will affect the normal operation of the heating wire, reduce the concentration of smoke generated, and affect the quality of smoke. In this embodiment, the life of the heating wire is first extended by alternating the heating wires, and secondly, by controlling the second heating wire at the bottom of the cotton core to work independently in the later stage, it can be ensured that the oil content at the bottom of the cotton core meets the requirements in the later stage of the use of the electronic atomizer, and there will be no burning phenomenon, thereby ensuring the atomization quality.

[0065] Furthermore, the dual heating wire includes a first heating wire and a second heating wire. When the working mode is a mixture of a single-shot alternating mode and a dual-shot mode, comparing the actual use time of the dual heating wire with the preset time threshold, and regulating the heating of the dual heating wire according to the comparison result includes:

[0066] S321: Obtaining a first heating time length and a second heating time length in which the first heating wire and the second heating wire work alternately in a single-shot alternating mode;

[0067] S322: Obtaining a third heating time and a conversion coefficient for the first heating wire and the second heating wire to heat together in the dual-heating mode, and obtaining a fourth heating time according to the third heating time and the conversion coefficient;

[0068] S323: when the sum of the first heating time, the second heating time and the fourth heating time is less than the preset time threshold, controlling the first heating wire and the second heating wire to maintain alternating operation in the single-shot alternating mode;

[0069] S324: When the sum of the first heating time, the second heating time and the fourth heating time is greater than or equal to the preset time threshold, the first heating wire is controlled to stop working and the second heating wire keeps working in the single-shot alternating mode.

[0070] Furthermore, the conversion coefficient is the ratio of the atomization time of the single-shot alternating mode to the atomization time of the double-shot alternating mode under the condition of the same heating value.

[0071] In this embodiment, when the user chooses to use the single-shot alternating mode and the double-shot mode in combination, the comparison of the preset time thresholds should comprehensively consider the heating time of the first heating wire and the second heating wire in the single-shot alternating mode and the heating time of the first heating wire and the second heating wire working together in the double-shot mode. Since the value of the preset time threshold is based on the single-shot alternating mode as an experimental basis, and the heating power of the heating wires in the two modes is different, it is necessary to use the same calorific value as the conversion quantity to convert the heating time of the first heating wire and the second heating wire working together in the double-shot mode into the heating time required in the single-shot alternating mode. The conversion coefficient is calculated as the ratio of the atomization time of the single-shot alternating mode to the atomization time of the double-shot alternating mode under the same calorific value. For example, to atomize 100 ml of oil, the double heating wires in the single-shot alternating mode require T1 seconds, and the double heating wires in the double-shot mode require T2 seconds. Therefore, the conversion coefficient is

[0072] At this time, the sum of the first heating time, the second heating time and the fourth heating time after conversion in the single-fire alternating mode is compared with the preset time threshold. In the dual-fire mode, whether or not the preset time threshold is exceeded, the dual-fire mode is not affected, that is, in the dual-fire mode, whether or not the preset time threshold is exceeded, the first heating wire and the second heating wire continue to heat at the same time until the oil in the oil tank is completely atomized. In the single-fire alternating mode, when the preset time threshold is exceeded, only the second heating wire is controlled to keep working, and the first heating wire stops working.

[0073] Furthermore, the total heat value and the double heating wire parameters required for atomizing all the oil in the oil tank are obtained, and the total atomization time required for atomizing all the oil in the oil tank is obtained according to the total heat value and the double heating wire parameters, including:

[0074] S11: Obtain the atomization parameter α of the oil and the oil tank capacity L;

[0075] S12: Obtain the resistance R, input voltage V and resistance variation coefficient k of the heating wire;

[0076] S13: According to the functional mapping relationship among the atomization parameter α, the oil tank capacity L, the resistance R and the input voltage V, the total atomization time T is obtained:

[0077]

[0078] Among them, the atomization parameter α is the heat required for atomization of each unit of oil.

[0079] In this embodiment, the calorific value (unit joule J) required for each unit of oil with different oil characteristics is obtained through experiments, and then the total heat required for the atomization of all the oil in the oil tank is obtained through the actual capacity unit number of the oil tank. Different oils have different oil characteristics, so there are certain differences in the heat required to consume the same unit of oil; the unit measurement of the oil can be calculated in milliliters or grams, and the unit of the atomization parameter α is joule per milliliter or joule per gram.

[0080] Regarding the value of the resistance variation coefficient k (Ω / ℃), in addition to comprehensively considering the parameters of the heating wire resistivity, heating wire length and heating wire cross-sectional diameter, it is also necessary to detect the heating wire temperature in real time and select the resistance value at the corresponding temperature. Therefore, it is necessary to set up a temperature detection device to detect the temperature of the heating wire in real time. The resistance variation coefficient k reflects the functional mapping relationship between the heating wire resistivity, heating wire length and heating wire cross-sectional diameter and the heating wire temperature. The resistance variation coefficient k is obtained through experimental data.

[0081] Furthermore, the step of determining the preset time threshold according to the smoke concentration generated when the dual heating wires are working and the total atomization time includes:

[0082] S21: Obtaining the smoke concentration generated when the dual heating wires are working;

[0083] S22: when the smoke concentration is less than a preset concentration threshold, obtaining the remaining oil volume in the current oil tank;

[0084] S23: determining the remaining atomization time required to atomize the remaining oil according to the remaining oil capacity;

[0085] S24: Determine a preset time threshold by the difference between the total atomization time and the remaining atomization time.

[0086] In this embodiment, based on the quality of the smoke, firstly, due to the continuous consumption of oil and the gravity of the oil, the oil content infiltrated in the cotton core is less at the upper end and more at the lower end. Therefore, when the same heating value is applied, the smoke concentration generated at the upper end of the cotton core will be lower than that at the lower end; secondly, due to the repeated use of the heating wire, the heating wire ages or impurities adhere to the surface of the heating wire, which will affect the normal operation of the heating wire and also cause the smoke concentration generated by the heating wire to decrease; therefore, whether the oil content in the cotton core is uneven or the heating wire ages, it will affect the smoke quality and ultimately affect the value of the preset time threshold.

[0087] Taking the above into consideration, the present invention arranges a smoke concentration detection device near the double heating wires to uniformly collect the smoke concentration (mg / m 3 ), when the smoke concentration is detected to be lower than a certain preset concentration threshold, it proves that the smoke quality cannot meet the user's taste requirements, and it is necessary to control the single-shot alternating mode to maintain only the normal operation of the second heating wire.

[0088] This embodiment simulates the user's puffing through an experiment, with the puffing time varying from 1 to 5 seconds, and detects the smoke concentration at the heating wire in real time. When the smoke concentration does not meet the requirements, the remaining oil capacity in the oil tank is detected, and the remaining atomization time is obtained by the calorific value of the remaining oil capacity in the oil tank, and finally the used time value is obtained by the difference between the total atomization time and the remaining atomization time; similarly, the amount of oil consumed in the oil tank can be detected, and the consumed calorific value can be calculated by the consumed oil amount, and finally the corresponding used time value can be calculated by the consumed calorific value; ideally, the used time value is the preset time threshold. Preferably, in addition to the different duration of each puff during the actual puffing process of the user, there are other uncertain factors, such as different puffing strengths and gas flow rates, which will affect the actual smoke concentration data. Therefore, the total duration of simulated puffing when reaching the preset concentration threshold can be compared with the calculated value of the used duration under the ideal state. If the total duration of the simulated puffing is less than the value of the used duration, the total duration of the simulated puffing is determined as the preset duration threshold; if the total duration of the simulated puffing is greater than the value of the used duration, the value of the used duration is determined as the preset duration threshold. The purpose of this setting is to maximize the reduction of the smoke concentration caused by other uncertain factors to be lower than the preset concentration threshold earlier by taking a smaller value, and the problem that the smoke concentration is actually lower than the preset concentration threshold cannot be accurately fed back by using the statistics of the duration. In addition, the preset time threshold corresponding to the calculation of heating wires with different parameters or oils with different characteristics should be different, and targeted experiments need to be carried out to determine.

[0089] Different groups of people have different taste requirements for the preset concentration threshold value, and a balanced and popular smoke concentration critical value should be comprehensively determined.

[0090] Furthermore, after obtaining the current working mode of the dual heating wire, comparing the actual use time of the dual heating wire with the preset time threshold, and regulating the heating of the dual heating wire according to the comparison result, the method further includes:

[0091] S41: Obtaining first-time puff data of a number of identical electronic atomizers and constructing a puff simulation model;

[0092] S42: Acquire a plurality of identical secondary puff data of the electronic atomizer, and compare them with the corresponding first puff data in the puff simulation model to obtain a first deviation ratio, and store the first deviation ratio and the secondary puff data in the puff simulation model;

[0093] S43: obtaining a plurality of identical three-puff data of the electronic atomizer, and comparing them with the corresponding two-puff data in the puff simulation model to obtain a secondary deviation ratio, and storing the secondary deviation ratio and the three-puff data in the puff simulation model;

[0094] S44: Similarly, obtain n times of puff data of the same electronic atomizer, and compare them with the corresponding n-1 times of puff data in the puff simulation model to obtain n-1 times of deviation ratio, and store the n-1 times of deviation ratio and the n times of puff data in the puff simulation model;

[0095] S45: Obtaining corresponding primary compensation values, secondary compensation values, ... n-1 compensation values ​​according to the primary deviation ratio, the secondary deviation ratio, ... the n-1 deviation ratio, and storing the primary compensation values, the secondary compensation values, ... the n-1 compensation values ​​in the suction simulation model;

[0096] S46: Determine the working parameters of the double heating wire for three puffs according to the one-time compensation value. And so on, determine the working parameters of the double heating wire for n+1 puffs according to the n-1-time compensation value.

[0097] Among them, the puffing data includes the dual heating wire working mode, the puffing time, the smoke concentration generated at the dual heating wire, and the smoke concentration at the nozzle.

[0098] In this embodiment, the smoke concentration generated at the dual heating wire during each puff can reflect the aging degree of the heating wire, while other factors such as the puffing time and gas flow rate will affect the smoke concentration at the mouthpiece. Therefore, a smoke detection device is added to the mouthpiece to detect the smoke concentration at the mouthpiece during each puff, which can most directly reflect the quality of the smoke at the entrance. When the smoke concentration at the mouthpiece is kept within a certain range, the taste of the electronic atomizer can be kept within a certain level. In this embodiment, a certain number of identical electronic atomizers are selected for experiments through simulated puffing, and the data of each puff is collected and summarized to construct a puffing simulation model, reflecting the situation that the dual heating wire gradually ages with the increase of the number of puffs under different puff times, resulting in changes in the puffing data.

[0099] Among them, in the same number of puff experiments, for example, in the first puff data, the puff time of different electronic atomizers simulates the situation in which the users have different lung capacities and the puff time is between 1-5 seconds, the puff strength is different, and the single-shot alternating mode or the double-shot mode is selected. The smoke concentration generated at the double heating wire and the smoke concentration at the mouthpiece during the puff are used to obtain the first puff database; in the first puff database, the double heating wire is brand new and used for the first time, and the puff data under different puff times and puff strengths are recorded, and the first puff double heating wire is in the best working state.

The compensation value is taken as follows: the smoke concentration at the nozzle after compensation should be greater than or equal to the preset concentration threshold. In this embodiment, the working parameters of the heating wire include voltage, current, resistance, temperature, etc.; the compensation value is preferably voltage compensation, and the problem of gradually decreasing atomized smoke concentration due to aging of the heating wire caused by fine-tuning the voltage compensation is improved.

At this time, the compensation value can also include temperature compensation and current compensation. The heating value of the heating wire is guaranteed by fine-tuning the current or temperature of the heating wire.
