[0051] At present, electronic atomization devices are usually powered by batteries. However, when electronic atomization devices are used in low-temperature environments, the polarization of the battery cells is aggravated, and the output voltage of the battery cells drops too much, which easily triggers the low-voltage protection of the electronic atomization device, causing the electronic atomization device to stop working, reducing the user's smoking experience of the electronic atomization device.

[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application.

[0054] Please refer to Figure 1 , which shows a schematic diagram of an application scenario of the electronic atomization device 100 provided by the embodiments of the present application. The electronic atomization device 100 may include a housing 101, a battery cell 102, a heating component 103, and a controller 104. The battery cell 102, the heating component 103, and the controller 104 may be installed in the housing 101, and the housing 101 may provide installation support for the battery cell 102, the heating component 103, and the controller 104.

[0055] Among them, the housing 101 may be provided with a medium cavity for storing the atomization medium. The atomization medium is used to generate aerosol after heating. The main components of the atomization medium may include glycerol, propylene glycol, flavor, nicotine, etc., which are not limited herein.

[0056] The material of the housing 101 may be any one of engineering plastics (for example, polycarbonate (PC), polystyrene (PS), polyamide (PA), polyimide (PI), etc.), aluminum alloy, stainless steel, or acrylonitrile butadiene styrene plastic (ABS plastic), etc., which are not limited herein.

[0057] The battery cell 102 may be electrically connected to the heating component 103 and the controller 104, and provide electrical energy for the heating component 103 and the controller 104.

[0058] The heating component 103 can be used to heat the atomization medium stored in the medium cavity so that the atomization medium generates an aerosol. The heating component 103 can be any one of a resistance heating element, an electromagnetic heating element, an infrared heating element, etc., and is not limited herein.

[0059] The controller 104 can be communicatively connected to the battery cell 102 and the heating component 103. The controller 104 can be used to control the battery cell 102 to supply electrical energy to the heating component 103 and control the heating component 103 to heat the atomization medium.

[0060] The controller 104 can be any one of a microcontroller unit (MCU), a central processing unit (CPU), a combinatorial logic controller (CLC), a complex programmable logic device (CPLD), or a field programmable gate array (FPGA), etc., and is not limited herein.

[0061] Please refer to Figure 2 , which shows a flowchart of a control method for an electronic atomization device provided by an embodiment of the present application. In a specific embodiment, the control method of the electronic atomization device can be applied to the controller 104 in the electronic atomization device 100 as shown in Figure 1 . Taking the controller 104 as an example, the process shown in Figure 2 will be elaborated in detail below. The control method of the electronic atomization device can include the following steps 210 to step 240.

[0062] Step 210: When it is determined that the electronic atomization device is puffed, determine whether the battery cell of the electronic atomization device is in a low-temperature environment.

[0063] In the embodiment of the present application, when the controller determines that the electronic atomization device is puffed, the no-load voltage and the loaded voltage of the battery cell can be determined, and based on the no-load voltage and the loaded voltage, it can be determined whether the battery cell is in a low-temperature environment. Since the polarization of the battery cell intensifies in a low-temperature environment and the output voltage of the battery cell drops too much, therefore, judging whether the battery cell is in a low-temperature environment based on the voltage change between the no-load voltage and the loaded voltage is beneficial to improving the accuracy of judging the environment where the battery cell is located.

[0064] Among them, the no-load voltage can be used to represent the open-circuit voltage of the battery cell without a load connected, and the loaded voltage can be used to represent the battery cell voltage when the battery cell operates at a preset output power.

[0065] The preset output power can be used to characterize the output power of the electronic atomization device that conforms to the user's puffing habit. The preset output power can be the output power preset by the user, or the output power automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., which is not limited here.

[0066] The electronic atomization device may further include a voltage sensor. The voltage sensor can be communicatively connected to the controller and can be used to collect the voltage of the battery cell.

[0067] The controller can respectively send a first control instruction to the battery cell and a first acquisition instruction to the voltage sensor. The battery cell receives and responds to the first control instruction and switches to an open-circuit state. The voltage sensor receives and responds to the first acquisition instruction, collects the voltage of the battery cell to obtain the no-load voltage, and sends the no-load voltage to the controller. The controller receives the no-load voltage returned by the voltage sensor.

[0068] The open-circuit state can be used to characterize the state where the battery cell is not connected to a load. The voltage sensor can be any one of a Hall effect voltage sensor, a voltage mutual inductor sensor, a voltage dividing resistor sensor, an optoelectronic voltage sensor, etc., which is not limited here.

[0069] The controller can respectively send a second control instruction to the battery cell and a second acquisition instruction to the voltage sensor. The battery cell receives and responds to the second control instruction and operates at the preset output power. The voltage sensor receives and responds to the second acquisition instruction, collects the voltage of the battery cell to obtain the loaded voltage, and sends the loaded voltage to the controller. The controller receives the loaded voltage returned by the voltage sensor.

[0070] Among them, the no-load voltage can be greater than or equal to the loaded voltage.

[0071] When the loaded voltage is greater than or equal to the first voltage threshold, it is determined that the battery cell is not in a low-temperature environment. The first voltage threshold can be used to characterize the maximum battery cell voltage when the battery cell is in a low-temperature environment. In a low-temperature environment, the battery cell voltage is relatively low. Judging the environment of the battery cell according to the voltage threshold is beneficial to improving the judgment accuracy.

[0072] The first voltage threshold can be the battery cell voltage preset by the user, or the battery cell voltage automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., which is not limited here.

[0073] As an example, the voltage threshold can be 3.3 volts (V), the voltage threshold can also be 3.5V, the voltage threshold can also be 3.1V, etc., which is not limited here.

[0074] When the loaded voltage is greater than the second voltage threshold and less than the first voltage threshold, calculate the voltage difference between the no-load voltage and the loaded voltage, and determine whether the battery cell is in a low-temperature environment based on the voltage difference. When the battery cell is in a low-temperature environment, the output voltage of the battery cell drops significantly. Judging the environment where the battery cell is located based on the voltage difference is beneficial to improving the judgment accuracy.

[0075] When the voltage difference is greater than the voltage difference threshold, it is determined that the battery cell is in a low-temperature environment; when the voltage difference is less than or equal to the voltage difference threshold, it is determined that the battery cell is not in a low-temperature environment.

[0076] The second voltage threshold is less than the first voltage threshold. The second voltage threshold can be used to represent the minimum battery cell voltage when the battery cell enters the low-voltage protection state. The second voltage threshold can be the battery cell voltage preset by the user, or the battery cell voltage automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., and is not limited here.

[0077] When the battery cell is in the low-voltage protection state, the battery cell is forced to stop providing power for the controller and the heating component of the electronic atomization device.

[0078] The voltage difference threshold can be used to represent the minimum voltage difference when the battery cell is in a low-temperature environment. The voltage difference threshold can be the voltage difference preset by the user, or the voltage difference automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., and is not limited here.

[0079] As an example, the voltage difference threshold can be 0.7V, the voltage difference threshold can also be 0.5V, the voltage difference threshold can also be 0.9V, etc., and is not limited here.

[0080] Step 220: When it is determined that the battery cell is in a low-temperature environment, determine the temperature-power coefficient of the battery cell.

[0081] In the embodiments of the present application, when the controller determines that the battery cell is in a low-temperature environment, the temperature-power coefficient of the battery cell can be determined.

[0082] Among them, the temperature-power coefficient can be used to represent the power attenuation ratio when the battery cell is in a low-temperature environment.

[0083] Specifically, when the controller determines that the battery cell is in a low-temperature environment, the voltage drop rate of the battery cell can be determined, and the value of the voltage drop rate is determined as the temperature-power coefficient. In a low-temperature environment, the voltage drop rate of the battery cell is proportional to the power attenuation ratio. Determining the value of the voltage drop rate of the battery cell in a low-temperature environment as the temperature-power coefficient improves the accuracy of the temperature-power coefficient.

[0084] Among them, the controller can control the voltage sensor to collect the cell voltage of the battery cell in real time, and calculate the voltage drop rate according to the cell voltages collected at any two collection times.

[0085] In an application scenario, the voltage sensor collects the cell voltage V at the first collection time t 1 of the battery cell, and the voltage sensor collects the cell voltage V at the second collection time t 1 of the battery cell. According to the cell voltage V 2 collected at the first collection time t 2 and the cell voltage V 1 collected at the second collection time t 1 , according to Formula 1, calculate the voltage drop rate |ΔV / Δt|, and determine the value ||ΔV / Δt|| of the voltage drop rate |ΔV / Δt| as the temperature power coefficient. 2 collected at the second collection time t 2 of the battery cell.

[0086] Formula 1 is: |ΔV / Δt| = |(V 2 - V 1 ) / (t 2 - t 1 )|.

[0087] Step 230: Determine the target output power of the battery cell according to the attenuation coefficient, preset output power and temperature power coefficient of the battery cell.

[0088] In the embodiment of the present application, the controller can determine the target output power of the battery cell according to the attenuation coefficient, preset output power and temperature power coefficient of the battery cell.

[0089] Among them, the attenuation coefficient can be used to characterize the attenuation ratio of the output power of the battery cell, and the attenuation coefficient is a constant. As an example, the attenuation coefficient can be k, and the value of k can be (0.05, 0.2), which is not limited here.

[0090] The preset output power can be the power preset by the user, or the power automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., which is not limited here.

[0091] In an application scenario, the attenuation coefficient of the battery cell can be k, the preset output power can be P 0 , and the temperature power coefficient can be ||ΔV / Δt||. According to the attenuation coefficient k, preset output power P 0 of the battery cell, and the temperature power coefficient ||ΔV / Δt||, according to Formula 2, calculate the target output power P n .

[0092] Formula 2 is: P n = P0 ×(1 - k×||ΔV / Δt||) = P 0 ×(1 - k×||(V 2 - V 1 ) / (t 2 - t 1 )||).

[0093] Step 240: Control the battery cell to operate at the target output power.

[0094] In the embodiment of the present application, the controller can send the target output power to the battery cell. The battery cell receives and responds to the target output power, and outputs the target output power. When it is determined that the electronic atomization device is being puffed in a low - temperature environment, by automatically reducing the output power of the battery cell, the output current of the battery cell decreases accordingly, and the voltage drop of the battery cell also decreases. This can effectively prevent the output voltage of the battery cell from dropping too much, and can suppress the problem that the low - voltage protection of the electronic atomization device is triggered, resulting in the electronic atomization device stopping working, which is beneficial to improving the puffing experience of users when puffing the electronic atomization device.

[0095] In some embodiments, when the no - load voltage is less than or equal to the second voltage threshold, or the loaded voltage is less than or equal to the second voltage threshold, control the battery cell to enter the low - voltage protection state, so that the battery cell is forced to stop providing power for the controller and the heating component of the electronic atomization device, which can suppress the damage of the battery cell caused by using the battery cell when the voltage of the battery cell is too low, and is beneficial to extending the service life of the battery cell.

[0096] The solution provided by the present application, when it is determined that the electronic atomization device is being puffed, determines whether the battery cell of the electronic atomization device is in a low - temperature environment, and when it is determined that the battery cell is in a low - temperature environment, determines the temperature - power coefficient of the battery cell. The temperature - power coefficient is used to characterize the power attenuation ratio of the battery cell in a low - temperature environment, and determines the target output power of the battery cell according to the attenuation coefficient of the battery cell, the preset output power, and the temperature - power coefficient. The attenuation coefficient is used to characterize the attenuation ratio of the output power of the battery cell, and controls the battery cell to operate at the target output power. When it is determined that the electronic atomization device is being puffed in a low - temperature environment, by automatically reducing the output power of the battery cell, the output current of the battery cell decreases accordingly, and the voltage drop of the battery cell also decreases. This can effectively prevent the output voltage of the battery cell from dropping too much, and can suppress the problem that the low - voltage protection of the electronic atomization device is triggered, resulting in the electronic atomization device stopping working, which is beneficial to improving the puffing experience of users when puffing the electronic atomization device.

[0097] Please refer to Figure 3 , which shows a flowchart of the control method of the electronic atomization device provided by another embodiment of the present application. In a specific embodiment, the control method of the electronic atomization device can be applied to the controller 104 in the electronic atomization device 100 as shown in Figure 1 shown below. Taking the controller 104 as an example, the following willFigure 3 The following steps 310 to 340 will be elaborated in detail according to the shown process. The control method of the electronic atomization device may include the following steps.

[0098] Step 310: Collect the gas flow rate in the air flow channel of the electronic atomization device.

[0099] In this embodiment, the electronic atomization device may further be provided with an air flow channel, and the air flow channel communicates with the medium cavity and the external space of the electronic atomization device.

[0100] The electronic atomization device may further include an air flow sensor. The air flow sensor may be disposed in the air flow channel and communicatively connected to the controller. The air flow sensor may be used to collect the gas flow rate in the air flow channel.

[0101] The controller may send a third collection instruction to the air flow sensor. The air flow sensor receives and responds to the third collection instruction, collects the gas flow rate in the air flow channel, and sends the gas flow rate to the controller. The controller receives the gas flow rate returned by the air flow sensor.

[0102] Among them, the air flow sensor may be any one of a resistive air flow sensor, a capacitive air flow sensor, a voltage air flow sensor, a grating air flow sensor, etc., and is not limited here.

[0103] Step 320: Determine whether the electronic atomization device is being puffed according to the gas flow rate.

[0104] In this embodiment, the controller may determine whether the electronic atomization device is being puffed according to the gas flow rate, realizing the suction detection of the electronic atomization device based on the collected gas flow rate in the air flow channel, and improving the detection accuracy of the suction detection of the electronic atomization device.

[0105] When the gas flow rate is greater than or equal to the gas flow rate threshold, it is determined that the electronic atomization device is being puffed; when the gas flow rate is less than the gas flow rate threshold, it is determined that the electronic atomization device is not being puffed.

[0106] Among them, the gas flow rate threshold may be used to represent the minimum gas flow rate in the air flow channel when the electronic atomization device is being puffed. The gas flow rate threshold may be a gas flow rate preset by the user, or a gas flow rate automatically generated by the controller according to the control process of controlling the electronic atomization device multiple times, etc., and is not limited here.

[0107] Step 330: When it is determined that the electronic atomization device is being puffed, determine whether the battery cell of the electronic atomization device is in a low-temperature environment.

[0108] In this embodiment, for the content of step 330, reference may be made to the corresponding steps in the foregoing embodiments, and details are not described herein again.

[0109] Step 340: When it is determined that the battery cell is not in a low-temperature environment, control the battery cell to operate at a preset output power.

[0110] In this embodiment, when the controller determines that the battery cell is not in a low-temperature environment, it can send a preset output power to the battery cell. The battery cell receives and responds to the preset output power, and outputs the preset output power, realizing that when it is determined that the electronic atomization device is being puffed in a non-low-temperature environment, controlling the electronic atomization device to operate at a preset output power that conforms to the user's puffing habit, improving the user's puffing experience of the electronic atomization device.

[0111] In some embodiments, after the controller controls the battery cell to operate at a preset output power, and when it is determined that the electronic atomization device has not been manipulated within a preset duration, the electronic atomization device can be controlled to enter a sleep state, which can suppress the problem that the power consumption of the electronic atomization device increases when the electronic atomization device has been in a working state all the time when the user has not puffed the electronic atomization device for a long time, and is beneficial to improving the energy efficiency utilization rate of the electronic atomization device.
