Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a control method for an atomizer, a storage medium, a battery rod, and an electronic atomization device. Background Technology

[0002] Electronic atomization devices typically include a reservoir for storing the aerosol-generating matrix and an atomizing core for heating the matrix. The aerosol-generating matrix is ​​transferred from the reservoir to the atomizing core via active or passive supply. In passive supply, the aerosol-generating matrix comes into contact with the absorbent surface of the atomizing core, and under gravity, it enters the core and is transferred from the absorbent surface to the atomizing surface for heating and atomization to generate an aerosol. Active supply uses a negative pressure provided by an air pump to draw the aerosol-generating matrix from the reservoir into the nozzle, which then sprays it onto the atomizing core to achieve heating and atomization.

[0003] During active liquid supply, risks such as liquid accumulation and insufficient atomization may occur due to users accelerating suction and / or increasing suction time. Summary of the Invention

[0060] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the electronic atomizing device provided in the embodiments of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional structure of the electronic atomizing device. Figure 3 yes Figure 1 The diagram shows the principle of adjusting the atomizing power of the atomizing core in the electronic atomizing device.

[0061] This embodiment provides an electronic atomizing device 100, which can be used to atomize an aerosol generating matrix. The electronic atomizing device 100 includes an atomizer 1 and a battery rod 2 connected to each other. The atomizer 1 is used to store and atomize the aerosol generating matrix to form an aerosol that can be inhaled by a user. The aerosol generating matrix can be a liquid matrix such as a medicinal liquid or plant leaf liquid. The atomizer 1 can be used in different fields, such as medical, beauty, and recreational inhalation; the following embodiments all take recreational inhalation as an example. The battery rod 2 includes a battery 21, an airflow sensor (not shown), and a controller (not shown); the battery 21 is used to provide electrical energy to the atomizer 1 so that the atomizer 1 can atomize the aerosol generating matrix to form an aerosol; the airflow sensor is used to detect changes in airflow in the electronic atomizing device 100, and the controller starts the electronic atomizing device 100 according to the changes in airflow detected by the airflow sensor. The battery rod 2 also includes other components such as a bracket, which are the same as or similar to those in the prior art. For details, please refer to the prior art, which will not be described again here. The atomizer 1 and the battery rod 2 can be integrated as one unit, such as sharing a single housing; or they can be detachably connected, depending on the specific needs of the design.

[0062] Specifically, the atomizer 1 includes a housing 11, an atomizing core 12, a jetting assembly 13, and a liquid storage chamber 14. The liquid storage chamber 14 stores the aerosol generation matrix. The jetting assembly 13 communicates with the liquid storage chamber 14 and jets the aerosol generation matrix from the liquid storage chamber 14 in droplet form. The atomizing core 12 atomizes these droplets to generate aerosol. The droplet size of the aerosol generated by the atomizing core 12 is much smaller than the droplet size ejected by the jetting assembly 13. The housing 11 has an installation space 111, within which the atomizing core 12 and the jetting assembly 13 are housed. The liquid storage chamber 14 can be housed within the installation space 111 or located outside the installation space 111, depending on the specific circumstances.

[0063] In this embodiment, the spray assembly 13 includes a micro-pump 131 and a nozzle 132. The micro-pump 131 is used to transfer the aerosol generating matrix in the liquid storage chamber 14 to the nozzle 132 through negative pressure, so that the aerosol generating matrix is ​​sprayed in droplet form through the nozzle 132. The micro-pump 131 can be controlled by the battery 21 or manually to transfer the aerosol generating matrix in the liquid storage chamber 14 to the nozzle 132. When the micro-pump 131 is controlled by the battery 21, the micro-pump 131 can be a piston pump or a vacuum pump. During the atomization process of the atomizer 1, the power of the spray assembly 13 is constant so that the liquid supply volume of one spray is basically consistent when the temperature of the aerosol generating matrix in the liquid storage chamber 14 remains constant. Specifically, when the spray assembly 13 includes the micro-pump 131, the constant power of the spray assembly 13 means that the rotation speed of the micro-pump 131 is constant, or the piston pump movement speed of the micro-pump 131 is constant.

[0064] In other embodiments, the spray assembly 13 includes a nozzle assembly. The liquid storage chamber 14 is a high-pressure liquid storage tank, in which the aerosol generating matrix exists under high pressure. The nozzle assembly is connected to the high-pressure liquid storage tank via a pipe, and a switch is installed on the pipe. By controlling the switch, the aerosol generating matrix in the high-pressure liquid storage tank can be sprayed through the nozzle assembly onto the atomizing core 12 to form droplets. The atomizing core 12 heats the droplets to generate aerosol. During the atomization process of the atomizer 1, the power of the spray assembly 13 is constant so that the liquid supply per spray remains basically consistent when the temperature of the aerosol generating matrix in the liquid storage chamber 14 remains constant. Specifically, when the spray assembly 13 includes a nozzle assembly, the constant power of the spray assembly 13 means that the switch on the pipe connecting the nozzle assembly and the high-pressure liquid storage tank is opened to the same degree each time.

[0065] In this embodiment, the atomizing core 12 includes a heating element (not shown), which is used to heat and atomize the droplets formed by the jetting assembly 13 to generate an aerosol. The heating element can be one of a heating wire, a heating plate, a heating mesh, etc.

[0066] The atomizer 1 also includes a temperature sensor 15 or a viscosity sensor 16. The temperature sensor 15 is disposed on the inner or outer wall of the liquid storage chamber 14, and is used to monitor the temperature of the aerosol-generating matrix in the liquid storage chamber 14 in real time. Optionally, the temperature sensor 15 is disposed on the bottom wall of the liquid storage chamber 14, so that the temperature of the aerosol-generating matrix can be accurately detected even when there is little remaining aerosol-generating matrix in the liquid storage chamber 14. The viscosity sensor 16 is disposed on the inner wall of the liquid storage chamber 14, and is used to monitor the viscosity of the aerosol-generating matrix in the liquid storage chamber 14 in real time. Optionally, the viscosity sensor 16 is disposed on the bottom and side walls of the liquid storage chamber 14, so that the viscosity of the aerosol-generating matrix can be accurately detected regardless of whether the atomizer 1 is in a horizontal or vertical orientation.

[0067] Battery rod 2 is coupled to atomizer 1 and is used to power the heating element in atomizer 1 and control the heating element to heat the atomized aerosol to generate the matrix. Battery rod 2 is also used to power micro pump 131 to control the operation of micro pump 131.

[0068] The battery rod 2 includes a battery 21, a processor 22, a memory 23, and an airflow sensor (not shown). The airflow sensor detects pressure changes during inhalation. The processor 22 is electrically connected to both the battery 21 and the memory 23. The battery 21 powers the atomizer 1 and the micro pump 131. The memory 23 stores program instructions for implementing the atomizer control method of any of the embodiments described below; the atomizer control method is detailed later. The processor 22 executes the program instructions stored in the memory 23; that is, the processor 22 retrieves the program instructions stored in the memory 23 to execute the atomizer control method of any of the embodiments described below.

[0069] The processor 22 can also be referred to as a CPU (Central Processing Unit). The processor 22 may be an integrated circuit chip with signal processing capabilities. The processor 22 can also be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. A general-purpose processor can be a microprocessor or any conventional processor.

[0070] The memory 23 can be a memory module, TF card, etc., and can store all the information in the device's electronic equipment, including the input raw data, computer programs, intermediate running results, and final running results. It stores and retrieves information according to the location specified by the controller. With the memory 23, the device has a memory function and can ensure normal operation. The memory 23 can be classified according to its purpose into main memory (RAM) and auxiliary memory (external storage), or it can be classified into external memory and internal memory. External storage is usually magnetic media or optical discs, which can store information for a long time. RAM refers to the storage components on the motherboard, used to store currently executing data and programs, but it is only used for temporary storage of programs and data; the data will be lost when the power is turned off or interrupted.

[0071] In one embodiment, the memory 23 stores a preset algorithm, which is a preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core 12. The processor 22 is used to acquire the viscosity of the aerosol generating matrix detected by the viscosity sensor 16, and analyze the atomization power of the atomizing core 12 corresponding to the current viscosity based on the received preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core 12, thereby adjusting the atomization power of the atomizing core 12.

[0072] In another embodiment, the memory 23 stores a preset algorithm, which is a preset correspondence between the temperature of the aerosol generating matrix and the atomization power of the atomizing core 12. The processor 22 is used to acquire the temperature of the aerosol generating matrix detected by the temperature sensor 15, and analyze the atomization power of the atomizing core 12 corresponding to the current temperature according to the received preset correspondence between the temperature of the aerosol generating matrix and the atomization power of the atomizing core 12, thereby adjusting the atomization power of the atomizing core 12.

[0073] In another embodiment, the memory 23 stores a preset algorithm, which is a preset correspondence between the time interval between two adjacent suction ports and the atomization power of the atomizing core 12. The processor 22 is used to acquire the time interval between two adjacent suction ports detected by the airflow sensor, and analyze the atomization power of the atomizing core 12 corresponding to the current time interval between two adjacent suction ports according to the received preset correspondence between the time interval between two adjacent suction ports and the atomization power of the atomizing core 12, thereby adjusting the atomization power of the atomizing core 12.

[0074] It is understandable that when a user vapes at a normal frequency and for a normal duration, the heat generated by the atomizing core 12 during atomization is insufficient to cause significant changes in the temperature or viscosity of the aerosol-forming matrix within the storage chamber 14. With the power of the spray assembly 13 remaining constant, the amount of liquid sprayed each time is almost constant. The atomizing core 12 atomizes at a predetermined power, ensuring that the droplets sprayed by the spray assembly 13 are atomized evenly and sufficiently. For example, when vaping at a frequency of 3 seconds followed by a 27-second pause, the short vaping time (3 seconds) results in a very short heating time for the atomizing core 12, and the interval between two vaping sessions (27 seconds) is much longer than the vaping time. On the one hand, although the atomizing core 12 is rapidly heated to the atomization temperature during the first puff, the heat from the atomizing core 12 is conducted to the aerosol generating matrix in the storage chamber 14, causing the temperature of the aerosol generating matrix to change significantly over a period of more than 3 seconds. Therefore, the puffing stops before the temperature of the aerosol generating matrix changes significantly, meaning the spray assembly 13 stops spraying and the atomizing core 12 stops heating. On the other hand, although the heat generated by the atomizing core 12 continues to be conducted to the aerosol generating matrix in the storage chamber 14 after it stops heating, causing the temperature of the aerosol generating matrix to change, the long time interval between puffs allows the aerosol generating matrix to cool back to its original temperature during this interval, preventing significant temperature changes. This ensures a stable amount of aerosol and a consistent taste. It is understandable that the time for a typical user to take a puff is 3-5 seconds, while for a special user it can be 7-8 seconds. Through the heat insulation design between the atomizing core 12 and the liquid storage chamber 14, it can be ensured that the temperature of the aerosol generation matrix will not change significantly due to the temperature of the atomizing core 12 during the time it takes to take a puff.

[0075] However, when the user accelerates the inhalation, for example, changing from 3 seconds of inhalation followed by 27 seconds of pause to 3 seconds of inhalation followed by 8 seconds of pause, the interval between the two inhalations is short. After the first inhalation, the heat generated by the atomizing core 12 is conducted to the aerosol generating matrix in the liquid storage chamber 14, causing the temperature of the aerosol generating matrix to change. Since the time interval between the next inhalation is insufficient for the aerosol generating matrix to drop back to its original temperature, the temperature of the aerosol generating matrix is ​​significantly higher when the next inhalation is taken than when the first inhalation was taken. Consequently, the viscosity of the aerosol generating matrix decreases, and its fluidity improves. Under the premise that the power of the spray component 13 remains constant, the amount of liquid sprayed at one time increases. If the atomizing core 12 is still atomized at its original predetermined atomization power, some droplets may not be atomized (i.e., liquid accumulation) or the atomization may be insufficient. The amount of aerosol generated by the atomizing core 12 is unstable, and the taste is unstable. Furthermore, when the user accelerates their inhalation, i.e., increases the inhalation frequency, it indicates that the user desires more aerosol, and the original preset atomization power of the atomizing coil 12 cannot meet the user's needs. Similarly, when the user increases the inhalation time (from 3 seconds of inhalation followed by 27 seconds of pause to 4 seconds of inhalation followed by 8 seconds of pause), the heat generated by the atomizing coil 12 causes the temperature of the aerosol-generating matrix in the storage chamber 14 to rise, resulting in a similar problem as mentioned above. In other words, the temperature or viscosity of the aerosol-generating matrix in the storage chamber 14 changes with different inhalation states. When the temperature of the aerosol-generating matrix in the storage chamber 14 rises or the viscosity decreases, the atomizing coil 12, operating at its original power, suffers from insufficient atomization.

[0076] This application uses a temperature sensor 15 to detect the temperature of the aerosol-generating matrix in the storage chamber 14, a viscosity sensor 16 to detect the viscosity of the aerosol-generating matrix in the storage chamber 14, or an airflow sensor to detect the time interval between two adjacent suction ports. Based on these parameters, the atomization power of the atomizing core 12 is adjusted to ensure that even when the user accelerates suction and / or increases the suction time, causing the temperature of the aerosol-generating matrix to rise, the droplets sprayed by the injection component 13 are atomized sufficiently, meeting the user's demand for a larger volume of aerosol. Specifically, when adjusting the atomization power of the atomizing core 12 according to the temperature or viscosity of the aerosol-generating matrix or the time interval between two adjacent suction ports, the amount of aerosol produced in the first few suction ports gradually increases as the temperature or viscosity of the aerosol-generating matrix gradually decreases, reaching a stable and larger aerosol volume after thermal equilibrium is achieved.

[0077] Please see Figure 4 , Figure 4 This is a flowchart illustrating the control method of the atomizer provided in the first embodiment of this application.

[0078] This embodiment provides a control method for an atomizer, which includes the following steps. The control method provided in this embodiment is applied to the electronic atomizing device described above, and the processor 22 in the battery rod 2 is the executing entity of the control method. The aerosol generating matrix used in this embodiment is liquid at room temperature.

[0079] S11: Obtain detection information of the aerosol generation matrix, including viscosity.

[0080] Specifically, the viscosity of the aerosol-generating matrix in the liquid storage chamber 14 is detected in real time by the viscosity sensor 16, and the detected viscosity is sent to the processor 22.

[0081] S12: Adjust the atomization power of the atomizing core based on the detection information of the aerosol generation matrix.

[0082] Specifically, during the atomization process, the power of the spray assembly 13 remains constant. Constant power of the spray assembly 13 refers to a constant rotation of the micro-pump 131 and a constant opening size of the nozzle 132. The lower the viscosity of the aerosol-generating matrix, the easier it is for the spray assembly 13 to spray it. In other words, the lower the viscosity of the aerosol-generating matrix, the more aerosol-generating matrix the spray assembly 13 can spray in a single pass at constant power. To avoid liquid accumulation, the atomization power of the atomizing core 12 needs to be adjusted.

[0083] Please see Figure 5 , Figure 5 yes Figure 4 A flowchart illustrating the process of obtaining the preset algorithm in step S12 of the control method for the provided atomizer.

[0084] S121: Obtain the preset correspondence between the viscosity of the aerosol generation matrix and the atomization power of the atomizing core.

[0085] Specifically, the preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core is obtained through the following method:

[0086] Step S1211: Obtain the atomization power of the atomizing core corresponding to the aerosol generation matrix of each viscosity.

[0087] Specifically, an aerosol generating matrix with a fixed viscosity is configured, and the power of the injection component 13 is fixed to obtain the atomization power of the atomizing core 12 corresponding to that viscosity.

[0088] Step S1211a: Obtain the liquid supply of the matrix generated by spraying a fixed viscosity aerosol once by the spraying component.

[0089] Specifically, the mass of the liquid storage chamber 14 before spraying and the mass of the liquid storage chamber 14 after the spraying assembly 13 sprays a fixed-viscosity aerosol to generate a matrix are obtained; the liquid supply is obtained based on the mass of the liquid storage chamber 14 before spraying and the mass of the liquid storage chamber 14 after spraying. In other words, the liquid supply of the liquid generation matrix by the spraying assembly 13 spraying a fixed-viscosity aerosol once under constant power is obtained by the weight reduction method.

[0090] Step S1211b: Based on the above liquid supply, determine the initial power of the atomizing core.

[0091] Specifically, the initial power of the atomizing core 12 corresponding to the liquid supply volume of the spray assembly 13 spraying once is determined based on empirical values, so as to avoid the initial power being too high when atomizing the above-mentioned liquid supply aerosol to generate the matrix and burning out the heating element, or too low when atomizing and failing to atomize sufficiently.

[0092] Step S1211c: Using the same liquid supply volume, increase the initial power multiple times to determine the upper limit power.

[0093] Specifically, using the same liquid supply, the initial power is increased until a burnt smell is produced by atomization, and this is determined to be the upper limit power. In other words, using the initial power as a reference value, the power of the atomizing core 12 is adjusted upwards multiple times until a burnt smell is produced by atomization at a certain power, and this is determined to be the upper limit power.

[0094] Step S1211d: Using the same liquid supply volume, reduce the initial power multiple times to determine the lower limit power.

[0095] Specifically, using the same liquid supply, the initial power is reduced until the atomization conversion rate is below a threshold, which is then determined as the lower limit power. The atomization conversion rate is the ratio of the amount of atomized droplets from the atomizing core 12 to the liquid supply. In other words, the atomization conversion rate is obtained by measuring the reduction in the aerosol generation matrix in the liquid storage chamber 14 before and after spraying, as well as the amount of aerosol sprayed by the atomizing core 12. That is, using the initial power as a reference value, the power of the atomizing core 12 is adjusted downwards multiple times until the atomization conversion rate is below a threshold, which is then determined as the lower limit power. Optionally, the threshold for the atomization conversion rate is 0.9; the threshold for the atomization conversion rate is designed according to requirements.

[0096] Step S1211e: Obtain the atomization power based on the upper limit power and the lower limit power.

[0097] Specifically, a power level between the upper and lower limits is selected as the atomization power. This power level ensures that the atomization conversion rate is neither too low, resulting in excessive energy loss, nor produces a burnt taste that affects the flavor. In one embodiment, the power level is selected between the upper and lower limits based on the desired flavor profile.

[0098] Optionally, the atomization power can be the average of the upper and lower power limits. In some embodiments, any point within the range of the upper and lower power limits can also be selected as the atomization power.

[0099] Step S1212: Based on aerosol generating matrices of different viscosities and the atomization power of the atomizing core corresponding to each aerosol generating matrice of different viscosities, a preset correspondence between the viscosity of the aerosol generating matrices and the atomization power of the atomizing core is obtained.

[0100] Specifically, aerosol generating matrices of different viscosities are configured, and the atomization power of the atomizing core 12 corresponding to each aerosol generating matrice of different viscosities is obtained through the same method as in step S1211. Using MATLAB / Excel, a preset correspondence between the viscosity of the aerosol generating matrices and the atomization power of the atomizing core 12 is obtained by fitting the viscosity data and the corresponding atomization power data.

[0101] It is understood that by using steps S1211 and S1212, a preset correspondence between the viscosity of a certain type of aerosol generating matrix and the atomization power of the atomizing core 12 can be obtained. By changing the type of aerosol generating matrix and repeating steps S1211 and S1212, preset correspondences between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core 12 for different types of aerosol generating matrices can be obtained.

[0102] S122: Adjust the atomization power of the atomizing core based on the viscosity of the aerosol generating matrix and the preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core.

[0103] It is understood that this step may also include obtaining the type of aerosol generation matrix, for example, obtaining the type of aerosol generation matrix in the storage chamber 14 according to the markings on the storage chamber 14; and selecting the preset correspondence between the viscosity of the corresponding aerosol generation matrix and the atomization power of the atomizing core 12 according to the type of aerosol generation matrix.

[0104] The atomizer control method provided in this application embodiment detects the viscosity of the aerosol-generating matrix in the storage chamber 14 using a viscosity sensor 16. Under the premise that the power of the injection component 13 remains constant, the atomization power of the atomizing core 12 is adjusted accordingly. This ensures that even when the user accelerates suction and / or increases the suction time, causing the temperature of the aerosol-generating matrix to rise, the droplets ejected by the injection component 13 are atomized sufficiently, meeting the user's demand for a larger aerosol volume. Specifically, when adjusting the atomization power of the atomizing core 12 based on the viscosity of the aerosol-generating matrix, the aerosol volume gradually increases in the first few puffs, achieving a stable and larger aerosol volume after reaching thermal equilibrium.

[0105] Please see Figure 6 , Figure 6 This is a flowchart illustrating the control method for the atomizer provided in the second embodiment of this application.

[0106] The difference between the atomizer control method provided in the second embodiment of this application and the atomizer control method provided in the first embodiment of this application is that the detection information is temperature.

[0107] S21: Obtain detection information of the aerosol generation matrix, including temperature.

[0108] Specifically, the temperature of the aerosol generation matrix in the liquid storage chamber 14 is detected in real time by the temperature sensor 15, and the detected temperature is sent to the processor 22.

[0109] S22: Adjust the atomization power of the atomizing core based on the detection information of the aerosol generation matrix.

[0110] Specifically, during the atomization process, the power of the spray assembly 13 remains constant. This constant power refers to the constant rotation of the micro-pump 131 and the constant opening size of the nozzle 132. The temperature of the aerosol-generating matrix is ​​related to its viscosity. Higher temperatures and lower viscosity make it easier for the spray assembly 13 to spray the aerosol-generating matrix. In other words, the higher the temperature of the aerosol-generating matrix, the more aerosol-generating matrix the spray assembly 13 can spray at a constant power. To avoid liquid accumulation, the atomization power of the atomizing core 12 needs to be adjusted.

[0111] Please see Figure 7 , Figure 7 yes Figure 6 A flowchart illustrating the process of obtaining the preset algorithm in step S22 of the control method for the provided atomizer.

[0112] S221: Obtain the preset correspondence between the temperature of the aerosol generation matrix and the atomization power of the atomizing core.

[0113] Specifically, in one embodiment, the preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core is obtained by the following method:

[0114] Step S2211a: Based on the aerosol generating matrix at different temperatures and the viscosity of the aerosol generating matrix corresponding to each temperature, a preset correspondence between the temperature of the aerosol generating matrix and the viscosity of the aerosol generating matrix is ​​obtained.

[0115] Specifically, the aerosol generating matrix was heated at different temperatures to obtain aerosol generating matrices at different temperatures. Viscosity sensors 16 were used to detect the viscosity of the aerosol generating matrix at each temperature, obtaining the corresponding viscosity. Using MATLAB / Excel, a preset correlation between the temperature and viscosity of the aerosol generating matrix was obtained by fitting the temperature data and the corresponding viscosity data.

[0116] Step S2212a: Obtain the preset correspondence between the viscosity of the aerosol generation matrix and the atomization power of the atomizing core.

[0117] In this embodiment, the specific implementation of step S2212a is the same as the specific implementation of step S121 in the control method of the atomizer in the first embodiment, and can achieve the same or similar technical effects, so it will not be described again.

[0118] Step S2213a: Based on the preset correspondence between the temperature of the aerosol generation matrix and the viscosity of the aerosol generation matrix, and the preset correspondence between the viscosity of the aerosol generation matrix and the atomization power of the atomizing core, the preset correspondence between the temperature of the aerosol generation matrix and the atomization power of the atomizing core is obtained.

[0119] It is understandable that steps S2211a and S2212a are not sequential. Steps S2211a-S2213a provide a preset correspondence between the temperature of a certain type of aerosol generating matrix and the atomization power of the atomizing core 12. By changing the type of aerosol generating matrix and repeating steps S2211a-S2213a, preset correspondences between the temperature of the aerosol generating matrix and the atomization power of the atomizing core are obtained for different types of aerosol generating matrices.

[0120] In one embodiment, the preset correspondence between the viscosity of the aerosol generating matrix and the atomization power of the atomizing core is obtained by the following method:

[0121] Step S2211b: Obtain the atomization power of the atomizing core corresponding to the aerosol generation matrix at each temperature.

[0122] Specifically, an aerosol generation matrix with a fixed temperature is configured, and the power of the injection component 13 is fixed to obtain the atomization power of the atomizing core 12 corresponding to that temperature.

[0123] In this embodiment, the specific implementation of step S2211b is similar to that of step S121 in the atomizer control method of the first embodiment, and will not be described again.

[0124] Step S2212b: Based on the aerosol generating matrix at different temperatures and the atomization power of the atomizing core corresponding to each aerosol generating matrix at each temperature, obtain the preset correspondence between the temperature of the aerosol generating matrix and the atomization power of the atomizing core.

[0125] Specifically, aerosol generating matrices at different temperatures are configured, and the atomization power of the atomizing core 12 corresponding to each aerosol generating matrice at different temperatures is obtained using the same method as in step S2211b. Based on the temperature data and the corresponding atomization power data, a preset correspondence between the temperature of the aerosol generating matrices and the atomization power of the atomizing core 12 is obtained by fitting the data using MATLAB / Excel.

[0126] Step S222: Based on the temperature of the aerosol generation matrix and the preset correspondence between the temperature of the aerosol generation matrix and the atomization power of the atomizing core, adjust the atomization power of the atomizing core.

[0127] It is understood that this step may also include obtaining the type of aerosol generation matrix, for example, obtaining the type of aerosol generation matrix in the storage chamber 14 according to the markings on the storage chamber 14; and selecting the preset correspondence between the temperature of the aerosol generation matrix and the atomization power of the atomizing core 12 according to the type of aerosol generation matrix.

[0128] The atomizer control method provided in this application embodiment detects the temperature of the aerosol-generating matrix in the liquid storage chamber 14 using a temperature sensor 15. Under the premise that the power of the injection component 13 remains constant, the atomization power of the atomizing core 12 is adjusted accordingly. This ensures that even when the user accelerates inhalation and / or increases the inhalation time, causing the temperature of the aerosol-generating matrix to rise, the droplets ejected by the injection component 13 are atomized sufficiently, meeting the user's demand for a larger aerosol volume. Specifically, when adjusting the atomization power of the atomizing core 12 based on the temperature of the aerosol-generating matrix, the aerosol volume gradually increases in the first few inhalations, achieving a stable and larger aerosol volume after reaching thermal equilibrium.

[0129] Please see Figure 8 , Figure 8 This is a flowchart illustrating the control method for an atomizer provided in the third embodiment of this application.

[0130] The control method for the atomizer provided in the third embodiment of this application differs from the control method for the atomizer provided in the first embodiment of this application in that: the user's inhalation frequency is detected, that is, the time interval between two adjacent inhalations is detected.

[0131] S31: Get the time interval between two adjacent suction ports.

[0132] Specifically, the time interval between two adjacent suction ports is detected by an airflow sensor.

[0133] S32: Adjust the atomization power of the atomizer coil based on the time interval between two adjacent inhalations.

[0134] Based on the above analysis, it can be understood that the temperature of the aerosol-generating matrix when the user takes the next puff is related to the time interval between adjacent puffs. If the time interval is large enough, the aerosol-generating matrix will cool down to its original temperature within the puff interval, preventing significant temperature changes. If the time interval is small, the time interval for the next puff is insufficient for the aerosol-generating matrix to cool down to its original temperature, meaning the temperature of the aerosol-generating matrix at the next puff will be significantly higher than at the first puff. Since the curve of the aerosol-generating matrix temperature in the storage chamber 14 first rising and then falling back to its original temperature after the user stops puffing can be obtained experimentally in advance, the relationship between the aerosol-generating matrix temperature and the puff interval time can be obtained. Therefore, even without considering the ambient temperature, the relationship between atomization power and puff interval time can also be obtained. This relationship between atomization power and puff interval time can be stored in the memory in advance. The atomization power of the atomizing core can be calculated using the puff interval time and the relationship between atomization power and puff interval time, thereby adjusting the atomization power of the atomizing core 12.

[0135] Specifically, a suction interval threshold can be set. If the suction interval time is greater than or equal to the suction interval threshold, it indicates that the time interval is long enough for the aerosol-generating matrix to cool down to its original temperature within the suction interval time, and step S31 continues, i.e., the atomization power of the atomizing core 12 is not adjusted. If the suction interval time is less than the suction interval threshold, it indicates that the time interval is insufficient for the aerosol-generating matrix to cool down to its original temperature within the suction interval time, and step S32 is executed.
