DETAILED DESCRIPTION

[0022] The disclosure will now be described clearly and comprehensively with reference to the accompanying drawings and examples. Apparently, the described examples herein are only a part of the embodiments of the present disclosure, not all of the embodiments. All other examples obtained by those skilled in the art based on the examples of the present disclosure without creative efforts shall fall within the protection scope of the present invention.

[0023] FIG. 1 is a schematic structural view of an electronic atomization device according to some examples of the present disclosure. As shown in FIG. 1, the electronic atomization device 100 may include a power module 10, a heating element 20, and a control module 30. The power module 10 may be connected to the heating element 20 and configured to supply power to the heating element 20. The control module 30 may be connected between the power module 10 and the heating element 20, that is, the control module 30 may be connected to both the power module 10 and the heating element 20. The control module 30 may be configured to receive a startup instruction from a user, and control the power module 10 to supply power to the heating element 20 according to the startup instruction. The heating element 20 may be configured to heat an aerosol-generating substance (such as tobacco or tobacco tar) received in the electronic atomization device 100. That is, in some examples, the power module 10 may be controlled by the control module 30 to supply power to the heating element 20, and the heating element 20 may operate under certain parameters and heat the aerosol-generating substance.

[0024] The power module 10 may be disposed inside the electronic atomization device 100. More specifically, the power module 10 may be implemented as a rechargeable battery or a battery pack. The power module 10 may also be an external power supply device connected to the electronic atomization device 100 through a power interface.

[0025] The heating element 20 may be made of a temperature-controlled heating material, or may be made of a non-temperature-controlled heating material. In some examples, the temperature-controlled heating material may be a material with a greater TCR (temperature coefficient of resistance) value, while the non-temperature-controlled heating material may be a material with a less TCR value.

[0026] When the heating element 20 is made of the temperature-controlled heating material, since the temperature-controlled heating material has a greater TCR value, a resistance value of the heating element may be detected by using a system circuit. During the operation of the electronic atomization device 100, a temperature-measuring resistor may be connected in series in a load circuit of the heating element 20, and the temperature-measuring resistor R1 may be arranged near the heating element 20. The resistance value of the temperature-measuring resistor R1 may be acquired or calculated according to a voltage across the temperature-measuring resistor R1 and a current flows through the temperature-measuring resistor R1 detected by the system circuit. A temperature of the temperature-measuring resistor R1 (that is, the temperature of the heating element 20) may be acquired by looking up a correspondence or mapping relationship between the resistance value of the temperature-measuring resistor R1 and the temperature. The temperature may be further fed back to the control module 30, and the control module 30 may control an operating parameter of the heating element 20 according to the temperature of the heating element 20. In this way, when the heating element 20 heats the aerosol-generating substance, the aerosols generated at various stages have consistent or uniform tastes, thereby improving the user experience.

[0027] When the heating element 20 is made of the non-temperature-controlled heating material, since the non-temperature-controlled heating material has a less TCR value, the resistance value of the heating element cannot be detected by using the above-mentioned system circuit. Therefore, in some examples of the present disclosure, the electronic atomization device 100 may further include a temperature control circuit capable of detecting both the TCR value of the temperature-controlled heating material and the TCR value of the non-temperature-controlled heating material. The temperature control circuit may be connected to the heating element 20 and the control module 30.

[0028] FIG. 2 is a schematic structural diagram of a temperature control circuit according to some examples of the present disclosure. As shown in FIG. 2, in some examples, the temperature-measuring resistor R1 may be disposed near the heating element, and may be connected in series in the load circuit of the heating element 20. In some examples, terminals VIN+ and VIN- may be respectively connected to output terminals of the power module, or may be connected to the output terminals of the power module through a voltage step-up/down circuit. Terminals VO+ and VO- may be respectively connected to the load circuit of the heating element. That is, the terminal VO+ may be an input terminal of the load circuit. The temperature-measuring resistor R1 may be connected between the terminals VIN+ and VIN-.

[0029] In some examples, a first differential operational amplifier U1 with a low amplification factor and a second differential operational amplifier U2 with a high amplification factor may be simultaneously utilized to sample or acquire the voltage across the temperature-measuring resistor R1. Herein, the first differential operational amplifier U1 may have a first amplification factor, the second differential operational amplifier U2 may a second amplification factor, and the first amplification factor may be less than the second amplification factor. If the temperature-measuring resistor R1 is made of the temperature-controlled heating material, the resistance value of the temperature-measuring resistor R1 may be measured and acquired through the first differential operational amplifier U1 with a low amplification factor. If the temperature-measuring resistor R1 is made of the non-temperature-controlled heating material, the resistance value of the temperature-measuring resistor R1 may be measured by the second differential operational amplifier U2 with a high amplification factor. That is, no matter whether the temperature-measuring resistor R1 is made of the temperature-controlled heating material or the non-temperature-controlled heating material, the resistance value of the temperature-measuring resistor R1 may be measured and acquired through the temperature control circuit of the present disclosure.

[0030] More specifically, as shown in FIG. 2, each of a non-inverting input terminal IN+ of the first differential operational amplifier U1 with a low amplification factor and a non-inverting input terminal IN+ of the second differential operational amplifier U2 with a high amplification factor may be connected to the terminal VIN+ and a first terminal of the temperature-measuring resistor R1. Each of an inverting input terminal IN- of the first differential operational amplifier U1 with a low amplification factor and an inverting input terminal IN- of the second differential operational amplifier U2 with a high amplification factor may be respectively connected to the input terminal VO+ of the load circuit and a second terminal of the temperature-measuring resistor R1. Each of a reference input terminal REF of the first differential operational amplifier U1 with a low amplification factor and a reference input terminal REF of the second differential operational amplifier U2 with a high amplification factor may be connected to the terminal VIN-.

[0031] During the operation of the electronic atomization device, if the heating element is made of the temperature-controlled heating material, a sampling voltage across the temperature-measuring resistor R1 may be acquired by reading a value AD-R1 outputted after the sampling and amplification performed by the first differential operational amplifier U1 with a low amplification factor. If the heating element is made of the non-temperature-controlled heating material, the sampling voltage across the temperature-measuring resistor R1 may be acquired by reading an value AD-R2 outputted after the sampling and amplification performed by the second differential operational amplifier U2 with a high amplification factor.

[0032] In some examples, the control module 30 may be configured to receive the sampling voltage across the temperature-measuring resistor R1 measured by the first differential operational amplifier U1 with a low amplification factor or the second differential operational amplifier U2 with a high amplification factor, and execute a method for controlling the heating element 20 of the electronic atomization device 20 provided in some examples of the present disclosure. That is, the control module 30 may be configured to control the output from the power module 10 to the heating element 20 according to the method for controlling the heating element 20, such that the heating element 20 may operate under a certain operating parameter. In this way, the aerosols generated by the electronic atomization device 100 after the atomization process may have consistent or uniform tastes during the suction, and the user experience may be improved.

[0033] More specifically, after the connections among the power module 10, the heating element 20, and the control module 30 are completed, the control module 30 may be configured to control the heating element 20 to operate under a first parameter value in a first time period, control the heating element 20 to operate under a second parameter value in a second time period, control the heating element 20 to operate under a parameter value reducing from the second parameter value to a third parameter value in a third time period, and control the heating element 20 to operate under the third parameter value in a fourth time period. In some examples, the second parameter value may be less than the first parameter value, and the third parameter value may be less than the second parameter value.

[0034] In summary, in some examples, the heating element 20 may operate under the first parameter value that is greater than the second parameter value in the first time period, and thus a heating efficiency of the heating element 20 may be increased, and the temperature of the heating element 20 may be rapidly increased. The heating element 20 may further operate under the second parameter value which is medium-sized in the second time period. Herein, "medium-sized" means that the second parameter value is less than the first parameter value and greater than the third parameter value. In the third time period, the heating element 20 may operate under a parameter value reducing from the second parameter value to the third parameter value, and the heating element 20 may continuously operate under the third parameter value in the fourth time period. In this way, it is possible to reduce the possibility that the heating element 20 has an excessively high temperature during the third and fourth time periods caused by the heat accumulation. Therefore, the aerosols generated by the electronic atomization device 100 at various stages have consistent or uniform tastes, thereby improving the user experience of suction.

[0035] In some examples, the first parameter value, the second parameter value, and the third parameter value may be constant. That is, the heating element 20 may operate under the constant first parameter value in the first time period, operate under the constant second parameter value in the second time period, and operate under the constant third parameter value in the fourth time period. In the third time period, however, the heating element 20 may operate with a parameter value gradually decreasing from the second parameter value to the third parameter value. For example, the parameter value may be linearly decreased from the second parameter value to the third parameter value.

[0036] In some examples, the second parameter value may be a preset output value acquired from the control module 30. In some examples, the preset output value may be a factory-set value. That is, a default value stored in the control module 30 before the electronic atomization device 100 is shipped from the factory.

[0037] In some examples, the preset output value may also be a value set by the user when using the electronic atomization device 100. For example, the preset output value may be a value set by the user in the control module 30 when the user uses the electronic atomization device 100 for the first time. In some examples, the preset output value may also be a value set by the user and included in the startup instruction received by the control module 30.

[0038] During the operation of the electronic atomization device 100, the control module 30 may receive the startup instruction. When a preset value of the second parameter value is stored in the electronic atomization device 100, the preset value may be utilized as the operative second parameter value, the first parameter value and the third parameter value may be acquired according to / by utilizing the operative second parameter value, and the heating element 20 may operate under the first parameter value, the second parameter value, and the third parameter value.

[0039] When the startup instruction includes an input value set for the second parameter value, the electronic atomization device 100 may utilize the input value as the operative second parameter value, and the first parameter value and the third parameter value may be acquired according to the operative second parameter value. The heating element 20 may further operate under the first parameter value, the second parameter value, and the third parameter value.

[0040] In some examples, a ratio of the first parameter value to the second parameter value may be set to be greater than or equal to 1.1, and may be less than or equal to 2. For example, the ratio of the first parameter value to the second parameter value may be 1.1, 1.15, 1.2, 1.3, 1.5, 2, and the like. In some examples, a ratio of the third parameter value to the second parameter value may be set to be less than or equal to 0.9, and may be greater than or equal to 0.5. For example, the ratio of the third parameter value to the second parameter value may be 0.9, 0.85, 0.8, 0.6, 0.5, and the like. Thus, the first parameter value and the third parameter value may be calculated or acquired from the second parameter value.

[0041] In some examples, the first time period, the second time period, the third time period, and the fourth time period may be temporally continuous time periods. That is, an ending point of the first time period is a starting point of the second time period, an ending point of the second time period is a starting point of the third time period, and an ending point of the third time period is a starting point of the fourth time period.

[0042] In some examples, a duration of the first time period may be greater than or equal to 5ms and may be less than or equal to 15ms. A duration of the second time period may be greater than or equal to 100ms and may be less than or equal to 300ms. A duration of the third time period may be greater than or equal to 10ms and may be less than or equal to 30ms. A duration of the fourth time period may be determined according to a specific time of the suction of the user. In some examples, as shown in FIGS. 3-5, the duration of the first time period may be less than the duration of the second time period, and further less than the duration of the third time period.

[0043] More specifically, in the first time period, the heating element may operate under the first parameter value for at least 5ms, such as 5ms, 6ms, 7ms, 10ms, 15ms, and the like. In the second time period, the heating element may operate under the second parameter value for at least 100ms, such as 100ms, 110ms, 130ms, 180ms, 200ms, 300ms, and the like. In the third period, the second parameter value may be reduced to the third parameter value, and the heating element 20 may operate for at least 10ms, such as 10ms, 12ms, 15ms, 20ms, 30ms, and the like.

[0044] The first parameter value, the second parameter value, and the third parameter value may be selected from the group consisting of a power value, a voltage value, and a temperature value. That is, the control module 30 may control the operation of the heating element 20 by controlling one of an operating power, an operating voltage, and an operating temperature of the heating element 20.

[0045] For example, in some example, the control module 30 may control the operating power of the heating element 20, such that the heating element 20 may operate at a first power value in the first time period, operate at a second power value less than the first power value in the second time period, operate at a power value decreasing from the second power value to a third power value, and operate at the third power value in the fourth time period.

[0046] FIG. 3 is a graph illustrating a relationship between a power W of the heating element and the time T according to some examples of the present disclosure. In some examples, more specifically, as shown in FIG. 3, the heating element 20 may firstly operate at a power Wa during a time period Ta. At the ending point of the time period Ta, the power Wa may be reduced to a power Wset, and the heating element 20 may operate at the power Wset during a time period Tb. Herein, the power Wa may be greater than Wset, such that a heating rate of the heating element in the cooling state may be increased. At a starting point of a time period Tbc, the power Wset may be gradually reduced, and the power may be reduced to a power Wc at an ending point of the time period Tbc. After that, the heating element 20 may continuously operate at the power Wc during the time period Tc until the end of the suction. Thus, it is possible to reduce the possibility that the heating element 20 has an excessively high temperature during the periods Tbc and Tc due to the heat accumulating performance of the heating element 20.

[0047] FIG. 4 is a graph illustrating a relationship between a voltage V of the heating element 20 and the time T according to some examples of the present disclosure. The control module 30 may be configured to control the operating voltage of the heating element 20. In some examples, as shown in FIG. 4, the heating element 20 may firstly operate at a voltage Va during the time period Ta. At the ending point of the time period Ta, the voltage Va may be reduced to a voltage Vset, and the heating element 20 may operate at the voltage Vset during the time period Tb. Herein, the voltage Va may be greater than Vset, such that a heating rate of the heating element in the cooling state may be increased. At a starting point of a time period Tbc, the voltage Vset may be gradually reduced, and the voltage may be reduced to a voltage Vc at an ending point of the time period Tbc. After that, the heating element 20 may continuously operate at the voltage Vc during the time period Tc until the end of the suction. Thus, it is possible to reduce the possibility that the heating element 20 has an excessively high temperature during the periods Tbc and Tc due to the heat accumulating performance of the heating element 20.

[0048] FIG. 5 is a graph illustrating a relationship between a temperature TEMP of the heating element 20 and the time T according to some examples of the present disclosure. The control module 30 may be configured to control the operating temperature of the heating element 20. In some examples, as shown in FIG. 5, at the starting point of the time period Ta, the control module 30 may be configured to control the heating element 20 such that the temperature of the heating element 20 may be increased from a room temperature to a temperature TEMPa, and the heating element 20 may operate at the temperature TEMPa during most of the time period Ta. At the ending point of the Ta period, the temperature of the heating element 20 may be reduced from the temperature TEMPa to a temperature TEMPset, and the heating element 20 may operate at the temperature TEMPset during the time period Tb. Herein, the temperature TEMPa may be greater than the temperature TEMPset, such that a heating rate of the heating element in the cooling state may be increased. At a starting point of the time period Tbc, the temperature TEMPset may be gradually reduced, and the temperature may be reduced to a temperature TEMPc at an ending point of the time period Tbc. After that, the heating element 20 may continuously operate at the temperature TEMPc during the time period Tc until the end of the suction. Thus, it is possible to reduce the possibility that the heating element 20 has an excessively high temperature during the periods Tbc and Tc due to the heat accumulating performance of the heating element 20.

[0049] In some examples, the time taken for increasing the temperature of the heating element from the room temperature to the temperature TEMPa may be controlled to be less than 1 ms, so as to shorten a preheating time of the heating element 20. In this way, the temperature of the heating element 20 may be rapidly increased to a normal heating temperature.

[0050] FIG 6 is a flow chart of a method for controlling the heating element of the electronic atomization device according to some examples of the present disclosure. The electronic atomization device 100 may be the electronic atomization device 100 according to some examples afore-mentioned. The method for controlling the heating element provided in some examples of the present disclosure may be executed by the control module 30 mentioned in the above examples to control the operation of the heating element 20. The method may include operations executed by the following blocks.

[0051] At block S10, in a first time period, the heating element 20 may be controlled to operate under a first parameter value.

[0052] At block S20, in a second time period, the heating element 20 may be controlled to operate under a second parameter value, and the second parameter value may be less than the first parameter value.

[0053] At block S30, in a third time period, the second parameter value may be controlled to be reduced to a third parameter value. That is to say, the heating element 20 may operate at a temperature gradually decreasing from the second parameter value to the third parameter value. In some examples, the heating element 20 may operate at a temperature linearly decreasing from the second parameter value to the third parameter value.

[0054] At block S40, in a fourth time period, the heating element 20 may be controlled to operate under the third parameter value.

[0055] The first parameter value, the second parameter value, and the third parameter value may be selected from the group consisting of a power value, a voltage value, and a temperature value. That is, it is possible to control the operation of the heating element 20 by controlling one of an operating power, an operating voltage, and an operating temperature of the heating element 20.

[0056] In some examples, the first time period, the second time period, the third time period, and the fourth time period may be temporally continuous time periods, such that the heating element 20 may continuously operate to generate aerosols.

[0057] In some examples, a duration of the first time period may be greater than or equal to 5ms, a duration of the second time period may be greater than or equal to 100ms, and a duration of the third time period may be greater than or equal to 10ms.

[0058] When the operation of the heating element 20 is controlled by controlling the operating temperature of the heating element 20, the block S10 may include: controlling a temperature of the heating element 20 to increase from the room temperature to the first parameter value, and controlling the heating element 20 to operate at the first parameter value.

[0059] More specifically, at the starting point of the first time period, that is, before controlling the heating element 20 to operate at the first temperature, it is also necessary to control the temperature of the heating element 20 to increase from the room temperature to the first temperature, such that the heating element 20 may operate at the constant first temperature for most of the first time period.

[0060] In some examples, the time required for increasing the temperature of the heating element 20 from the room temperature to the first temperature may be controlled to be less than 1 ms, so as to shorten a preheating time of the heating element. In this way, the temperature of the heating element 20 may be rapidly increased to a normal heating temperature.

[0061] In some examples, the second parameter value may be a preset output value. For example, the preset output value may be a factory-set value, or a value inputted in the electronic atomization device 100 by the user via an input module when the user is activating the electronic atomization device 100. When the second parameter value is set by the user, the second parameter value may be flexibly adjusted according to the aerosol-generating substances of different types, such that the aerosols having better tastes may be generated from the tobacco or tobacco tar of different types. The method may further include: acquiring the first parameter value and the third parameter value from the second parameter value.

[0062] Further, a ratio of the first parameter value to the second parameter value may be set to be greater than or equal to 1.1, and may be less than or equal to 2. For example, the ratio of the first parameter value to the second parameter value may be 1.1, 1.15, 1.2, 1.3, 1.5, 2, and the like. In some examples, a ratio of the third parameter value to the second parameter value may be set to be less than or equal to 0.9, and may be greater than or equal to 0.5. For example, the ratio of the third parameter value to the second parameter value may be 0.9, 0.85, 0.8, 0.6, 0.5, and the like. Thus, the first parameter value and the third parameter value may be calculated or acquired from the second parameter value.

[0063] An electronic atomization device may also be provided in some examples of the present disclosure. The electronic atomization device may include at least one processor and a storage medium communicating with the at least one processor.
