[0002] An electronic atomizer is an electronic product that mimics a cigarette, having the same appearance, smoke, taste, and feel. It is a product that uses atomization and other methods to turn nicotine and other substances into vapor for users to inhale.

[0003] The existing methods for detecting remaining e-liquid in related technologies involve setting up a first electrode and a second electrode within the atomizing chamber. This is achieved by first acquiring the electrical parameters of the circuit containing the first and second electrodes, then obtaining a table corresponding to the electrical parameters and e-liquid levels, and finally determining the remaining e-liquid level in the atomizing chamber based on the electrical parameters and the table. However, this method requires selecting different electrical parameters for different types of e-liquid, and the corresponding tables must be collected manually, resulting in low detection efficiency and accuracy. Consequently, it cannot accurately and promptly detect the remaining e-liquid level in the atomizing chamber, easily leading to a burnt taste due to the user's failure to notice insufficient e-liquid or a low e-liquid level, affecting the user experience and potentially generating harmful substances.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0052] An electronic atomizer is an electronic product that mimics a cigarette, having the same appearance, smoke, taste, and feel. It is a product that uses atomization and other methods to turn nicotine and other substances into vapor for users to inhale.

[0053] The existing methods for detecting remaining e-liquid in related technologies involve setting up a first electrode and a second electrode within the atomizing chamber. This is achieved by first acquiring the electrical parameters of the circuit containing the first and second electrodes, then obtaining a table corresponding to the electrical parameters and e-liquid levels, and finally determining the remaining e-liquid level in the atomizing chamber based on the electrical parameters and the table. However, this method requires selecting different electrical parameters for different types of e-liquid, and the corresponding tables must be collected manually, resulting in low detection efficiency and accuracy. Consequently, it cannot accurately and promptly detect the remaining e-liquid level in the atomizing chamber, easily leading to a burnt taste due to the user's failure to notice insufficient e-liquid or a low e-liquid level, affecting the user experience and potentially generating harmful substances.

[0054] Based on the above, this application provides a method, device, electronic cigarette, system, and storage medium for detecting the remaining e-liquid, which can automatically, promptly, and accurately detect the remaining e-liquid, improving the user experience and safety.

[0055] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0056] The first aspect of this application specifically provides a method for detecting the remaining amount of e-liquid, applied to electronic cigarette atomizing devices, such as... Figure 1 As shown. Methods for detecting remaining e-liquid include, but are not limited to, the following steps:

[0057] Step S100: Obtain the TPM parameters of the electronic atomizing device, the total e-liquid volume, and the preset power required per unit of e-liquid for atomization;

[0058] Step S200: Determine the total amount of atomization power required to atomize all the e-liquid based on the power required to atomize a unit of e-liquid and the total amount of e-liquid.

[0059] Step S300: Obtain the first total power consumption of the electronic atomizing device when atomizing e-liquid;

[0060] Step S400: Based on the first total power consumption, total atomization power consumption, power consumption required to atomize a unit of e-liquid, and TPM parameters, the remaining e-liquid quantity is obtained.

[0061] It's important to note that the TPM parameter characterizes the degree of e-liquid atomization in an e-cigarette atomizing module under different heating powers. Because the actual output heating power decreases as the battery in the e-cigarette atomizing device is consumed, the e-liquid may not be completely atomized. The TPM parameter is used to redetermine the amount of electricity required to atomize a unit of e-liquid. TPM stands for Total Particle Measure, which translates to the total number of atomized particles.

[0062] It should be noted that the total e-liquid volume refers to the amount of e-liquid transferred into the e-cigarette atomizing device's e-liquid tank 16, which can be the allowable e-liquid volume, i.e., filling the e-cigarette atomizing device's e-liquid tank 16 completely.

[0063] It should be noted that the power required per unit of e-liquid is the initial power required per unit of e-liquid. As the total power in the e-cigarette atomizing device is consumed, the current power required per unit of e-liquid is updated according to the TPM parameter. If it is the first time using the e-cigarette atomizing device, the remaining e-liquid in tank 16 is obtained based on the power required per unit of e-liquid and the remaining power obtained from the first total power consumption and the total atomization power. If it is not the first time using the e-cigarette atomizing device, the power required per unit of e-liquid is updated using the TPM parameter to obtain the power required per unit of e-liquid for the current single use. Then, the remaining e-liquid is obtained by using the updated power required per unit of e-liquid and the remaining power. This method can automatically and promptly detect the remaining e-liquid in the e-liquid tank 16. Introducing the TPM parameter can improve the accuracy of detecting the remaining e-liquid and display the remaining e-liquid level so that users can observe the remaining e-liquid level in a timely manner. At the same time, it simulates the display of the remaining e-liquid level to prevent the atomizer from burning dry and avoid the electronic atomizer from burning due to insufficient e-liquid or too low e-liquid level, thereby improving the user experience and safety.

[0064] For example, refer to Figures 9 to 12The provided electronic cigarette atomizing device includes a housing 1, a sealing ring 2, an atomizing core 3, a fuel tank sealant 4, a fuel tank sealing bracket 5, an LED light panel 6, a bottom cover 7, a microphone sealing ring 8, a microphone 9, a charging interface 10, a charging interface sealing ring 11, a control circuit board 12, a battery 13, a fuel filling hole plug 14, a fuel filling hole 15, and a fuel tank 16. The bottom cover 7 is provided with a charging hole 17, an air inlet 18, and an atmospheric pressure sensing hole 19. The sealing ring 2, atomizer core 3, oil tank sealant 4, and oil tank sealing bracket 5 are assembled on the outer shell 1. E-liquid is injected into the oil tank 16 through the oil filling hole 15. The oil filling hole plug 14 is inserted into the oil filling hole 15 to block the oil tank 16, providing atomization for the atomizer core 3. The control circuit board 12 is fixed to the bottom cover 7. The microphone sealing ring 8 is inserted into the microphone 9 to seal the air passage. The battery 13 is connected to the main board to provide power output voltage for the atomizer core 3 to work and produce atomization. The LED light board 6 is connected to the main board. The control module, i.e., the MCU chip, controls and outputs relevant display instructions to be displayed on the LED light board 6. That is, the LRD light board 6 represents the display module. The sealing ring 2 is inserted into the Type-C interface to prevent air leakage. The bottom cover 7 with the main board assembled is installed into the outer shell 1 to form the complete device. The total e-liquid volume is the total e-liquid volume that the oil tank 16 is allowed to hold. The control circuit board 12 is the control module in the electronic atomization device. The control module is used to determine the first total power consumption when atomizing e-liquid based on the output power and working time, and to obtain the remaining e-liquid volume based on the total atomization power, the power required to atomize a unit of e-liquid, the first total power consumption, and the TPM parameter.

[0065] Specifically, Figure 9 An exploded view of an electronic smoke atomizing device; Figure 10 The left image in the image is a BB cross-section view of the electronic cigarette atomizing device from the side, and the right image is an AA cross-section view of the electronic cigarette atomizing device from the front. Figure 11 From top to bottom, the top, bottom, and bottom views are the front view, side view, and rear view of the bottom cover 7; 12 indicates the airflow path in the electronic cigarette atomizing device and specifically indicates the direction of the airflow from the inlet and the mouthpiece. The airflow flows into the electronic cigarette atomizing device through the air inlet 18 on the bottom cover 7 and finally flows out from the air outlet provided at the outer shell 1.

[0066] Reference Figures 2 to 4 It is understood that the electronic cigarette atomizing device is equipped with a microphone module, and step S300 includes, but is not limited to, the following steps:

[0067] Step S310: Obtain the output power of the microphone module of the electronic atomizing device during a single atomization of e-liquid at the current moment, and the working time of the microphone module corresponding to the output power;

[0068] Step S320: Based on the output power and working time, obtain the power consumption of the electronic atomizing device in a single atomization of e-liquid at the current moment.

[0069] Step S330: Add the single power consumption to the second total power consumption of the electronic cigarette atomizing device before the current moment to obtain the first total power consumption.

[0070] It should be noted that the microphone module is used to detect whether there is a smoking action at the smoking sensor module. When the user puts it in their mouth, the microphone module detects the smoking state, wakes up and activates the microphone module. After the microphone module is activated, it will generate output power. The electronic detection module in the e-cigarette atomizing device detects the output power of the microphone module and obtains the working time of the microphone module corresponding to the output power. The single power consumption, output power and working time during a single atomization of e-liquid are added together with the second total power consumption of the e-cigarette atomizing device before the current moment to obtain the first total power consumption.

[0071] It should be noted that in the circuit connection of the electronic cigarette atomizing device, the device includes a microphone module, a power detection module, a control module, and a display module. One end of the microphone module is connected to a smoke sensor module. The microphone module detects whether the smoke sensor module is in a smoking state and determines whether to activate it based on the sensor's status. The power detection module is connected to the microphone module and detects its output power and the corresponding operating time. The control module is connected to both the microphone module and the power detection module. Based on the output power and operating time, the control module determines the initial total power consumption during e-liquid atomization. It also calculates the remaining e-liquid level based on the total atomization power, the power required to atomize a unit of e-liquid, the initial total power consumption, and the TPM parameter. The display module is connected to the control module and displays the remaining e-liquid level. The microphone module corresponds to... Figure 9 The microphone in the middle is number 9.

[0072] In some embodiments, using This indicates the current cell charge level in battery 13. This indicates the preset initial charge level of the battery cell when it leaves the factory. The sampling resistor represents the output current. This indicates the amount of electricity required to vaporize a unit of e-liquid. This indicates the total amount of e-liquid in the electronic cigarette atomizer. When using the electronic cigarette atomizer, the sampling resistor is periodically and cyclically monitored. The voltage at both ends is recorded and the corresponding sampling time and voltage are recorded. After the smoking action ends, the recorded data is processed, and data that deviates significantly from the preset output voltage curve or deviates significantly from the preceding and following data are treated as false readings and deleted. Then, based on the characteristics of the voltage output curve, if the recorded voltage data has a small dispersion, the voltage is directly calculated. If the recorded voltage data has a large dispersion, analyze the data characteristics and derive the time function of the voltage; then, based on the output current sampling resistor... The output current-time function is derived from the voltage-time relationship; the current-time function is integrated to obtain the single-cycle power consumption of this smoking session. (mAh); then according to the formula Calculate the amount of e-liquid consumed per unit of smoke. Finally, according to the formula... - What you get is the amount of e-liquid remaining after this smoking session.

[0073] Reference Figure 2 and Figure 4 It is understood that step S400 includes, but is not limited to, the following steps:

[0074] Step S410: Based on the first total power consumption and the total atomization power, obtain the remaining power of the electronic atomizing device;

[0075] Step S420: Based on the remaining power, the power required to atomize a unit of e-liquid, and the TPM parameter, obtain the remaining e-liquid quantity.

[0076] It should be noted that if this is the first time using the e-cigarette atomizing device, the remaining e-liquid amount in tank 16 is obtained based on the power required to atomize a unit of e-liquid and the remaining power obtained from the first total power consumption and the total atomization power. If this is not the first time using the e-cigarette atomizing device, the power required to atomize a unit of e-liquid is updated using the TPM parameters to obtain the power required to atomize a unit of e-liquid for the current single atomization. Then, the remaining e-liquid amount is obtained using the updated power required to atomize a unit of e-liquid and the remaining power. Here, "first time using the e-cigarette atomizing device" refers to the battery in the e-cigarette atomizing device being fully charged.

[0077] Reference Figure 6 It is understood that step S400 includes, but is not limited to, the following steps:

[0078] Step S401: When the electronic atomizing device is in the smoking state, the remaining e-liquid amount is obtained based on the first total power consumption, total atomization power, power required to atomize a unit of e-liquid, and TPM parameters. The working state is determined by the microphone module.

[0079] It should be noted that the microphone module is used to detect whether there is a smoking action at the smoking sensor module. When the user puts it in their mouth, the microphone module detects the smoking state and wakes up and activates the signal to obtain the first total power consumption of the electronic atomizing device when atomizing e-liquid.

[0080] In some embodiments, refer to Figure 8 , Figure 8 In Indicates storage system, This indicates the total amount of electricity required for the e-liquid. The unit is mAh, and ET represents when The change in battery level is obtained by subtracting the current battery level from the battery level in the battery cells and then summing the results. This indicates the current battery cell charge. The currently measured battery cell charge is stored in... When the microphone module is activated by a signal, its operating status is determined. These statuses include alarm mode, smoking mode, and charging mode. When the microphone module is charging, the alarm time is cleared. A charging indicator is displayed, and the system checks for any smoking activity during charging. If smoking is detected, the system returns to the smoking mode check. If no smoking activity occurs, the system measures the current battery level after charging is complete and checks if the current battery level is greater than [a certain value]. The battery cell charge level is greater than the current battery cell charge level. The battery cell capacity is updated. The battery charge in the device is the battery charge stored in the electronic cigarette atomizing device at the current moment. If the current state is not cleared, the system will return to the standby state awaiting wake-up; otherwise, it will directly return to the standby state awaiting wake-up.

[0081] Reference Figure 7 Understandably, the second total power consumption is obtained through the following steps:

[0082] Step S331: When the working state of the electronic cigarette atomizing device is alarm state, and the alarm time of the electronic cigarette atomizing device in alarm state is greater than the alarm preset threshold, the alarm power consumption corresponding to the alarm time is added to the third total power consumption of the electronic cigarette atomizing device before the current time to obtain the second total power consumption.

[0083] It should be noted that the second total power consumption includes the cumulative power consumed by the electronic atomizing device in smoking and alarm states before the current moment.

[0084] For example, when the microphone module is in alarm mode, if the cumulative alarm time is greater than 20 minutes (i.e., the preset alarm threshold is 20 minutes), the battery level of the electronic cigarette atomizing device is measured at the current moment. If the battery level is less than the value stored in the memory... When the battery cell charge is in the middle, update The battery charge in the device is the battery charge stored in the electronic cigarette atomizing device at the current moment. Then return to standby waiting to be woken up; check if the e-liquid alarm indicator is activated. If so, display the e-liquid alarm; otherwise, display normal smoking and check if smoking is complete. Continue until smoking is complete, then measure the current battery level. When the current battery level is less than... The battery cell capacity is updated. The battery charge in the device is the battery charge stored in the electronic cigarette atomizing device at the current moment. In the process, when the change in the battery cell charge in ES is subtracted from the current battery cell charge and the sum of the changes is added, it is determined whether ET is greater than 1. When ET> When the alarm is active, the e-liquid alarm flag will be set; otherwise, the system will return to standby mode and wait to be woken up.

[0085] It is understood that when the electronic atomizing device is in charging mode, the formula for calculating the remaining e-liquid volume is as follows:

[0086] , ,

[0087] in, This indicates the total amount of e-liquid. This indicates the total amount of e-liquid consumed. This indicates the amount of remaining e-liquid. This indicates the amount of electricity required for the atomizing unit of e-liquid. This indicates the preset initial charge level of battery 13 in the electronic cigarette atomizing device when it leaves the factory. This indicates the current charge level of battery 13. This indicates the cumulative charge amount after the electronic cigarette atomizing device has been charged multiple times during the charging state.

[0088] Specifically, for rechargeable e-cigarettes, when the e-cigarette atomizing device is detected to be in a charging state, the sampling resistor is periodically and cyclically monitored. The voltage at both ends is recorded, along with the corresponding sampling time and voltage. After the charging state ends, the recorded data is processed, and data that deviates significantly from the preset input voltage curve or from the preceding and following data are considered false readings and deleted. Based on the characteristics of the voltage output curve, if the recorded voltage data has low dispersion, the median voltage value is directly calculated; if the recorded voltage data has high dispersion, the data characteristics are analyzed, and the voltage time function is derived. Then, based on the current sampling resistor... The current-time function is derived from the voltage-time relationship; the current-time function is then integrated to obtain the single-charge capacity after this charging cycle. And record it. When calculating e-liquid consumption, use the formula... The total e-liquid consumption is obtained. .when and 0.1 In such cases, the alarm time for running out of e-liquid needs to be appropriately delayed based on the cumulative total power consumption of the battery. Indicates the number of charging cycles. This indicates the cumulative charge amount after multiple charging cycles.

[0089] In some embodiments, when the remaining e-liquid level is less than a preset threshold for the e-liquid level of the electronic atomizer, the operating state is switched to alarm state. By setting a preset threshold for e-liquid level, an alarm is triggered when the remaining e-liquid level is less than the preset threshold, allowing users to promptly observe the remaining e-liquid level, preventing the atomizer from burning dry, and avoiding a burnt taste caused by insufficient e-liquid or a low e-liquid level, thus improving the user experience and safety.

[0090] For example, refer to Figure 13 , Figure 13 This indicates the relationship between e-liquid consumption and battery capacity, through... Figure 13 It can more intuitively show the relationship between the amount of e-liquid consumed with each puff and the battery capacity.

[0091] Secondly, embodiments of this application also provide an electronic cigarette atomizing device, referring to... Figure 2 and Figure 3 The electronic cigarette atomizing device includes a microphone module, a power detection module, a control module, and a display module. One end of the microphone module is connected to a smoke sensor module, which detects whether the smoke sensor module is in a smoking state and determines whether to activate it based on the sensor's status. The power detection module is connected to the microphone module and detects its output power and the corresponding operating time. The control module is connected to both the microphone module and the power detection module. It determines the initial total power consumption during e-liquid atomization based on the output power and operating time. The control module also calculates the remaining e-liquid level based on the total atomization power, the power required to atomize a unit of e-liquid, the initial total power consumption, and the TPM parameter. The display module is connected to the control module and displays the remaining e-liquid level.

[0092] It should be noted that, Figure 2 In this diagram, MT1 represents the smoke sensor module, U1 represents the microphone module, U2 represents the control module, U3 represents the power detection module, and CON1 is also the charging interface 10. The battery cell is located between B+ and B-. The connection relationships between the charging interface 10, the smoke sensor module, the microphone module, the battery cell, the control module, the display module, and the power detection module are as follows: Figure 3As shown. The microphone module is used to detect whether there is a smoking action at the smoking sensor module. When the user puts the e-liquid in their mouth, the microphone module detects the smoking state, wakes up and activates the microphone module, and then generates output power. The electronic detection module in the e-cigarette device detects the output power of the microphone module and obtains the corresponding working time of the microphone module. The electronic detection module outputs the output power to the control module through the SCL and SDA interfaces. The single power consumption, output power, and working time of a single e-liquid atomization are added to the second total power consumption of the e-cigarette device before the current moment to obtain the first total power consumption. Through this e-cigarette device, the remaining e-liquid in the e-liquid tank 16 can be detected in time. Introducing the TPM parameter can improve the accuracy of the detection of the remaining e-liquid and display the remaining e-liquid, so that the user can observe the remaining e-liquid status in time. At the same time, simulating the display of the remaining e-liquid prevents the atomizer from burning dry and avoids the e-cigarette from burning due to insufficient e-liquid or too low e-liquid level, thus improving the user experience and safety.

[0093] Specifically, the TPM parameter is used to characterize the degree of e-liquid atomization in the atomizing module of an e-cigarette atomizing device under different heating powers. Since the actual output heating power is not constant as the battery power in the e-cigarette atomizing device is consumed, it will decrease. This may result in the e-liquid in the e-cigarette not being completely atomized. The TPM parameter is used to redetermine the amount of electricity required to atomize a unit of e-liquid.

[0094] Understandably, electronic cigarette atomizing devices also include an atomizing module, which is connected to the microphone module. The atomizing module is used to heat and atomize the liquid e-liquid.

[0095] It should be noted that an atomizing module is located between OUT- and OUT+. This atomizing module is a resistance wire and is used to heat the e-liquid, causing the e-liquid components to change from liquid to gas, thereby producing smoke for the user to inhale.

[0096] Thirdly, this application provides a cartridge-type electronic cigarette, including a cigarette holder, a cartridge, and an electronic atomizing device. The cigarette holder is equipped with a battery, and the cartridge is equipped with an oil tank for holding e-liquid. The cigarette holder is connected to the cartridge and the electronic atomizing device, respectively. The electronic atomizing device is used to perform the e-liquid remaining quantity detection method as described in the first aspect above.

[0097] In this embodiment, the user needs to replace the e-liquid cartridge before it runs out. The remaining e-liquid level detection method can detect the amount of remaining e-liquid in the cartridge in a timely and accurate manner, so that the user can observe the remaining e-liquid level in time, prevent the atomizer from burning dry, and avoid the electronic atomizer from burning due to insufficient e-liquid or too low e-liquid level, thereby improving the user experience and safety.

[0098] In addition, a fourth aspect of this application also provides a system for detecting the remaining amount of e-liquid, the system comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor.
