[0051] An embodiment of the present application provides an electronic atomization device 100, such as Figure 1 As shown, the electronic atomization device includes a housing 10, and the housing 10 has a first end 11 and a second end 12 arranged opposite to each other in the length direction. The first end 11 is provided with a mouthpiece 111 of the electronic atomization device 100, and the mouthpiece 111 is used for the aerosol generated by the electronic atomization device 100 to escape, so that the user can inhale the aerosol by sucking on the mouthpiece 111. The second end 12 is provided with an air inlet 121 for external air to enter the electronic atomization device 100, and a liquid storage chamber 20 is provided in the housing 10, and the liquid storage chamber 20 is used to store a liquid matrix that can be atomized. An air guide tube 30 extends longitudinally in the liquid storage chamber 20, and one end of the air guide tube 30 is connected to the mouthpiece 111. In order to seal the liquid storage chamber 20 and prevent the liquid matrix in the liquid storage chamber 20 from leaking out, a sealing member 40 is also provided in the housing 10, and the sealing member 40 is interference fit with the inner wall of the housing 10 to seal the liquid storage chamber 20.

[0052] The air guide tube 30 is provided with a liquid guiding element 31 and a heating element 32 combined with the liquid guiding element 31. The liquid guiding element 31 partially extends into the liquid storage chamber 20. The liquid guiding element 31 is made of a hygroscopic material, such as any one of non-woven fabrics, cotton fibers, glass fibers or porous materials. The heating element 32 can be combined with the liquid guiding element 31 by printing, deposition, sintering or physical assembly, or wound on the liquid guiding element 31, so that the liquid matrix in the liquid storage chamber 20 can be absorbed by the liquid guiding element 31. The liquid guiding element 31 further transfers the liquid matrix to the heating element 32 through the tiny gaps or microporous structures inside it. The heating element 32 heats the liquid matrix to generate aerosol, and releases the aerosol in the air guide tube 30.

[0053] The seal 40 is provided with an air vent 41 which is connected to the air duct 30. When the user inhales at the mouthpiece 111, external air enters the electronic atomization device 100 through the air inlet 121, then flows into the air vent 41 through the internal air flow channel, and enters the air duct 30 through the air vent 41, and finally carries the aerosol in the air duct 30 to flow to the mouthpiece 111 for the user to inhale.

[0054] The electronic atomization device 100 further includes an airflow sensing element 50, a battery cell 60 and a main board 70. The main board 70 is provided with a controller of the electronic atomization device 100. The airflow sensing element 50, the battery cell 60 and the heating element 32 are all electrically connected to the main board 70. When the user inhales at the mouthpiece 111, negative pressure is generated inside the electronic atomization device 100. The airflow sensing element 50 senses the negative pressure and generates a sensing signal, which is sent to the controller. The controller controls the battery cell 60 to provide the heating element 32 with the electric energy required for heating according to the sensing signal.

[0055] In some embodiments, the controller can be a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a single chip microcomputer, an ARM (Acorn RISC Machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components. In addition, the controller can also be any conventional processor, controller, microcontroller or state machine. The controller can also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP, and / or any other such configuration.

[0056] In the above electronic atomization device 100, the liquid storage chamber 20, the air guide tube 30, the liquid guide element 31 and the heating element 32 are combined to form an atomization component, and the airflow sensing element 50, the battery cell 60 and the main board 70 are combined to form a power supply component, which is used to provide electrical energy to the atomization component. At the same time, it should be noted that the method of heating the liquid matrix to generate aerosol by the electronic atomization device 100 is not limited to the above embodiment, and those skilled in the art can also use other well-known methods to heat the liquid matrix to generate aerosol.

[0057] Based on the above-mentioned electronic atomization device 100, an embodiment of the present application provides a method for determining the power level of the electronic atomization device 100, so as to more accurately determine the remaining power of the battery cell 60 without adding a power meter, such as Figure 2 As shown, the method includes:

[0058] S10, obtaining the power parameter of the battery cell 60 before the electronic atomization device is inhaled;

[0059] During the operation of the electronic atomization device 100, the battery cell 60 needs to provide electrical energy to the heating element 32, so the power parameter of the battery cell 60 will gradually decrease as the battery cell 60 discharges. The power parameter of the battery cell 60 can be expressed by SOC. SOC (State-of-Charge) refers to the remaining power of the battery cell 60, also known as the state of charge of the battery cell. The remaining power of the battery cell 60 is usually expressed in the form of a percentage. For convenience, the SOC of the battery cell 60 is usually expressed as follows:

[0060] SOC=Qc / Qn x 100%

[0061] In the formula, Qc refers to the remaining available power of the battery cell 60 at a certain moment, and Qn refers to the rated capacity of the battery cell 60, that is, the capacity of the battery cell 60 after it is fully charged. Alternatively, the power parameter of the battery cell 60 can also be a specific capacity value. As the battery cell 60 continues to discharge, the capacity value of the battery cell 60 will gradually decrease, and when the battery cell 60 is charged, the capacity value of the battery cell 60 will gradually increase. Alternatively, the power parameter of the battery cell 60 can also be the voltage value at both ends of the battery cell 60, and the voltage value at both ends of the battery cell 60 will also gradually decrease as the battery cell 60 continues to discharge.

[0062] S20, recording the cumulative puffing time of the electronic atomization device during the puffing process, during which the battery cell 60 outputs power to the heating element 32;

[0063] According to the above content, the electronic atomization device 100 is provided with an airflow sensing element 50. When the user inhales, negative pressure is generated inside the electronic atomization device 100, and the airflow sensing element 50 can sense the negative pressure. At this time, a timer (not shown) can be set in the electronic atomization device 100. The timer is electrically connected to the controller. When the controller starts to receive the sensing signal sent by the airflow sensing element 50, the controller controls the timer to start timing. When the inhalation is completed, the airflow sensing element 50 no longer senses the negative pressure, and the airflow sensing element 50 no longer generates a sensing signal, and then the controller no longer receives the sensing signal sent by the airflow sensing element 50. The controller can control the timer to stop timing, so that the time recorded by the timer is the user's inhalation time.

[0064] Alternatively, in some embodiments, the timer may also record the working time of the heating element 32. After the controller receives the sensing signal sent by the airflow sensing element 50, the controller starts to control the heating element 32 to work. When the controller no longer receives the sensing signal sent by the airflow sensing element 50 after the puffing is completed, the controller controls the heating element 32 to stop heating. Therefore, recording the working time of the heating element 32 can basically represent the user's puffing time.

[0065] The puffing time may be the cumulative time of a single puff by the user, for example, if a puffing process of the user lasts for 1 second, the cumulative puffing time is 1 second; or the puffing time may be the cumulative time of multiple puffs by the user, for example, if the user puffs 3 times in a row, each puff lasting 1 second, the cumulative puffing time is 3 seconds.

[0066] S30, determining a remaining power parameter of the battery cell after the electronic atomization device is puffed based on the accumulated puffing time and a total puffing time preset in the electronic atomization device.

[0067] According to the relationship between energy and power: W = Pt, where P represents power, W represents the energy consumed by an object within a period of time, and t represents this period of time. Since the battery cell 60 basically outputs electrical energy in a constant power manner during the puffing process, the amount of electrical energy provided by the battery cell 60 to the heating element 32 depends on the user's puffing time. The longer the user puffs, the more electrical energy the battery cell 60 provides to the heating element 32, that is, the more electricity the battery cell 60 releases. In addition, during the puffing process, the battery cell 60 mainly provides electrical energy to the heating element 32, and other electronic components such as indicator lights consume less power.

[0068] Secondly, during the design process of the electronic atomization device 100, the designer usually pre-sets the total puffing time of the electronic atomization device 100. For example, when the battery cell 60 is fully charged, the electronic atomization device 100 can provide 300 puffs for the user. Assuming that the duration of each puff is 1 second, the total puffing time is 300 seconds. Then, through the above-mentioned cumulative puffing time and total puffing time, the remaining power parameters of the battery cell 60 of the electronic atomization device 100 after puffing can be determined.

[0069] like Figure 2 As shown, as a specific embodiment, when the power parameter of the battery cell 60 is represented by the remaining power, that is, SOC, the step of determining the remaining power parameter of the battery cell after the electronic atomization device is puffed based on the accumulated puffing time and the total puffing time preset in the electronic atomization device may include:

[0070] S31, comparing the accumulated puffing time with the total puffing time to obtain a first ratio;

[0071] S32, calculating the difference between the remaining power of the battery cell before the suction and the first ratio;

[0072] S33, updating the difference to the remaining power of the battery cell after suction.

[0073] For example, before a certain puff, the remaining power of the battery 60 is 50%, and during the puffing process, the user's cumulative puffing time is 2S, and the total puffing time that the battery 60 can maintain after being fully charged is 100S. The SOC consumed during this puffing process is 2S / 100S, that is, 2%. Then, after this puffing, the SOC of the battery 60 is 50%-2%=48%, that is, the remaining power of the battery 60 after the puffing is 48%, and the controller then saves the remaining power of 48% after the puffing, so that it can be calculated based on the remaining power of 48% at the next puffing. When the SOC of the battery 60 drops to 10%-20%, the controller is set to not respond to the feedback signal of the airflow sensing element so that when the user continues to puff, the heating element 32 is controlled not to start, and the indicator light is controlled to provide feedback to the user to remind the user to charge the electronic atomization device 100 in time.

[0074] Therefore, through the method provided in this embodiment, there is no need to add a power meter to the electronic atomization device 100 to monitor the power of the battery cell 60. It is only necessary to monitor the user's puffing time, and based on the puffing time and the total puffing time of the electronic atomization device 100, the remaining power parameters of the battery cell 60 can be obtained. This power determination method is simple to operate and has high accuracy.

[0075] In some embodiments, when the battery cell 60 is in a charging state, the power level of the battery cell 60 after charging can also be determined by the above-mentioned embodiment. Specifically, since the battery cell 60 is basically constant current in the early stage of the charging process, and constant voltage in the latter stage of the fast charging process, the current will have a small fluctuation during the constant voltage period, but the constant voltage time is short, so it can be approximately considered that the entire charging process is constant current. Therefore, the method also includes:

[0076] Obtaining the remaining power of the battery cell of the electronic atomization device before charging;

[0077] Recording the charging time of the electronic atomization device, and comparing the charging time with the total charging time of the electronic atomization device to obtain a second ratio;

[0078] The remaining power and the second ratio are summed, and the sum is updated to the remaining power of the battery cell of the electronic atomization device after charging.

[0079] Specifically, when the battery cell 60 starts to charge, the controller controls the timer to start recording the charging time according to the calculation formula under the charging state:

[0080] Charging SOC = charging capacity / total cell capacity = charging current x charging time / average charging current * total charging time (1)

[0081] When the charging current remains constant, that is, constant current, the above formula (1) can be converted to:

[0082] Charging SOC = charging time / total charging time (2)

[0083] Therefore, according to formula (2), the charging SOC can be obtained by only knowing the charging time and the total charging time. When the charging current is constant, the total charging time is also constant. Then, the controller compares the charging time with the total charging time based on the charging time recorded by the timer to obtain a second ratio. The second ratio is the charging SOC during this period. The SOC obtained during the charging period is summed with the SOC before charging to obtain the SOC of the battery cell 60 after charging.

[0084] The total charging time is the time required for the battery cell 60 to be fully charged from the cutoff capacity to the rated capacity according to the preset charging current, and the cutoff capacity is the capacity corresponding to the battery cell 60 being discharged to the cutoff voltage. The preset charging current is different, and the total charging time is also different. The total charging time can be provided by the manufacturer of the battery cell 60, and the manufacturer of the electronic atomization device 100 then writes the total charging time into the controller of the electronic atomization device 100 through software.

[0085] In some embodiments, to avoid excessive charging cycles of the battery cell 60 resulting in a reduction in the life of the battery cell 60 , and thus a large deviation between the SOC calculated in the above embodiment and the actual SOC of the battery cell 60 , preferably, the battery cell 60 is only charged 4 to 6 times.

[0086] For example, the liquid matrix stored in the electronic atomization device 100 can be disposable, and the atomization component and the power supply component of the electronic atomization device 100 are non-detachable, so that the atomization component cannot be replaced. If the atomization component cannot be replaced, the power supply component cannot be reused multiple times. After the liquid matrix is ​​consumed, the entire electronic atomization device 100 needs to be discarded. By injecting an appropriate amount of liquid matrix, the liquid matrix can be consumed after the battery cell 60 is charged for 4 to 6 cycles, thereby avoiding the battery cell 60 from having a life attenuation after multiple charging cycles, resulting in a reduction in the total suction time that the battery cell 60 can maintain, thereby affecting the accuracy of the power calculation by this method.

[0087] In some embodiments, the method for determining the power level of the electronic atomization device further includes:

[0088] After each puffing action is completed, the remaining power parameter of the battery cell 60 is updated.

[0089] The airflow sensor can sense each puffing action of the user, and the controller can obtain the puffing duration of the puffing action through the timer, and then calculate the power consumed by the puffing action based on the puffing duration and the total puffing duration, and calculate the remaining power parameters of the battery cell after the puffing action based on the power before the puffing.

[0090] Through the above steps, the controller can update the remaining power parameters of the battery cell 60 after each puffing action, which is beneficial to improving the accuracy of determining the power level of the electronic atomization device 100 using this method.

[0091] And, in some embodiments, when the user continuously inhales multiple times in a short period of time, in order to facilitate the controller to control, the obtaining of the cumulative inhalation time of the electronic atomization device includes:

[0092] S21, obtaining the time interval between two adjacent puffing actions;

[0093] S22: If the time interval is less than a preset time, the accumulated puff time is the sum of the puff times of the two adjacent puff actions.

[0094] Specifically, a preset duration is pre-set in the controller. When the user continuously puffs multiple times in a short period of time, the controller controls the timer to record the duration of each puff, and the controller controls to obtain the time interval between any two adjacent puff actions, and compares the time interval with the preset duration. If the time interval is less than the preset duration, the controller controls to add the two adjacent puff durations, and then compares the added cumulative puff duration with the total puff duration to obtain a first ratio, without comparing each puff duration with the total puff duration. In this way, when the user continuously puffs multiple times in a short period of time, the controller can be conveniently controlled.

[0095] In some embodiments, Figure 3 As shown, before obtaining the accumulated puffing time of the electronic atomization device, the method further includes:

[0096] Obtaining a temperature value fed back by the temperature sensing element;

[0097] comparing the temperature value to a threshold temperature;

[0098] If the temperature value is less than the threshold temperature, the control stops obtaining the accumulated puff time.

[0099] Since the amount of electricity that can be released by the battery cell 60 will be reduced at a lower temperature, continuing to calculate the SOC of the battery cell 60 in the above manner will result in a large difference between the calculated SOC and the actual SOC of the battery cell 60, thereby affecting the user's judgment of the actual amount of electricity in the battery cell 60. Through the method provided by this embodiment, when the electronic atomization device 100 is at a lower ambient temperature, the controller controls to stop continuing to calculate the current SOC in the above manner, so as to avoid the calculation method feeding back the wrong battery cell SOC to the user.

[0100] Specifically, a temperature sensing element may be provided in the electronic atomization device 100. The temperature sensing element is used to sense the external environment temperature. The temperature sensing element is electrically connected to the controller, so that the controller can obtain the temperature value fed back by the temperature sensing element. At the same time, a threshold temperature is provided in the controller. For example, the threshold temperature may be 0 degrees. When the controller obtains the temperature value fed back by the temperature sensing element, the controller controls the temperature value to be compared with the threshold temperature. If the temperature value is less than the threshold temperature, the controller controls to stop obtaining the cumulative puffing time when the user puffs. Since there is no specific value of the cumulative puffing time, the cumulative puffing time cannot be compared with the total puffing time of the electronic atomization device 100, and thus the first ratio in the above embodiment cannot be obtained.

[0101] When the electronic atomization device 100 is in a low-temperature environment, or the electronic atomization device 100 is idle for a long time, the capacity of the battery cell 60 will be reduced, and the amount of electricity that can be released by the battery cell 60 will also be reduced. At this time, the current SOC value calculated according to the above-mentioned method for determining the amount of electricity will have a large deviation from the actual SOC of the battery cell 60. Therefore, in some embodiments, the electronic atomization device 100 may also pre-store a correspondence table between the voltage value at both ends of the battery cell 60 and the electricity parameters, so that the electronic atomization device 100 can compare the electricity parameters pre-stored in the correspondence table with the electricity parameters calculated by the above-mentioned method for determining the amount of electricity, thereby calibrating whether the electricity parameters calculated by the method for determining the amount of electricity are reasonable. Specifically, if Figure 4 As shown, the calibration method includes:

[0102] S40, obtaining the voltage value of the battery cell after being sucked;

[0103] S50, acquiring a pre-stored power parameter corresponding to the voltage value according to the correspondence table;

[0104] S60, comparing the remaining power parameter of the battery cell after the pumping with the pre-stored power parameter;

[0105] S70, if the difference between the remaining power parameter of the battery cell after being sucked and the pre-stored power parameter exceeds a preset value, adjusting the remaining power parameter of the battery cell after being sucked to the pre-stored power parameter.

[0106] In some embodiments, the correspondence table of the voltage values ​​at both ends of the battery cell 60 and its power parameters can be a correspondence table of the voltage value and SOC of the battery cell 60. The correspondence can be provided by the manufacturer of the battery cell 60, and then the manufacturer of the electronic atomization device 100 writes the correspondence into the controller through a software program for storage.

[0107] Furthermore, after obtaining the SOC of the battery cell 60 after each puff according to the above-mentioned method for determining the amount of electricity, the controller further obtains the voltage value across the battery cell 60 after puffing, and searches for the pre-stored SOC corresponding to the voltage value according to the above-mentioned corresponding table. The controller compares the SOC calculated by the method for determining the amount of electricity with the pre-stored SOC in the corresponding table. If the difference between the two exceeds the preset value, it means that the SOC calculated by the method for determining the amount of electricity has a large error, and the controller controls the SOC to be adjusted to the SOC pre-stored in the corresponding table.

[0108] For example, after a certain puff, the current voltage value of the battery cell 60 is 3.8V, and the current SOC after this puff calculated by the power level determination method is 58%, and according to the corresponding relationship in the corresponding table, the corresponding pre-stored SOC is 40% when the current voltage value is 3.8V. The difference between the current SOC calculated by the power level determination method and the pre-stored SOC in the corresponding table is 18%, and the difference exceeds the preset value of 10%. The controller determines that there is a large error in the current SOC, and adjusts the current SOC to 40%.

[0109] Alternatively, in some embodiments, the SOC corresponding to the current voltage value may also be a range. For example, the current voltage value of the battery cell 60 is 3.8V, and the corresponding SOC according to the corresponding table is 40% to 45%. At this time, the controller compares the current SOC 58% with the SOC upper limit 45% corresponding to the current voltage value. The difference between the two is 13%, which exceeds the preset value of 10%. The controller controls the current SOC to be adjusted to 45%, or to the average value of the SOC upper limit 45% and lower limit 40% corresponding to the current voltage value.

[0110] And, in some embodiments, the calibration method can be executed after each puff of the user, so as to determine whether there is a large error in the current SOC after each puff of the user; or, in some embodiments, the calibration method can also be executed once a day, for example, it can be executed after the 30th puff of the day, or at 6 pm every day.

[0111] And in some embodiments, before the electronic atomization device 100 leaves the factory, the first SOC of the battery cell 60 can be obtained through the corresponding table, and when the user takes the first puff, the SOC after the user's first puff can be calculated according to the above power calculation method. Alternatively, in some embodiments, the user can also operate the electronic atomization device 100 before the first puff to obtain the first SOC according to the corresponding table.

[0112] Further, such as Figure 5 As shown, the controller includes: at least one processor; and a memory connected to the at least one processor in communication. Figure 5 A processor is taken as an example. The memory stores instructions that can be executed by at least one processor, and the instructions are executed by at least one processor so that at least one processor can execute the control method of the above embodiment. The processor and the memory can be connected via a bus or other means. Figure 5 The example of connecting through bus is taken in the following.

[0113] The processor can be implemented by using at least one of the following: an application specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a processor, a controller, a microcontroller, a microprocessor, and other electronic units that perform these functions.

[0114] The memory includes a high-speed random access memory and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device. In some embodiments, the memory may optionally include a memory remotely arranged relative to the processor, and these remote memories may be connected to the aerosol generating device via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0115] The memory is used to store non-volatile software programs, non-volatile computer executable programs and modules, such as program instructions / units corresponding to the control method / device involved in this article. The processor executes various functional applications and data processing of the aerosol generating device by running the non-volatile software programs, instructions and units stored in the memory, that is, realizing the control method described in the above embodiment.
