[0062] Understandably, the fifth sub-circuit 35 and the sixth sub-circuit 36 in the third sub-switch circuit 23 can control the connection terminal 45 to electrically connect to the high-level terminal VBAT or the low-level terminal F GND of the power supply circuit 10.
[0063] In some embodiments, the control circuit 30 can be used to control the on / off state of each switching device, selectively or periodically control the current to flow from the first terminal 43 to the connection terminal 45 or from the connection terminal 45 to the first terminal 43, and / or control the current to flow from the second terminal 44 to the connection terminal 45 or from the connection terminal 45 to the second terminal 44.
[0064] Understandably, the control circuit 30 can control the first switching device Q1 and the sixth switching device Q4 to be turned on, while the second switching device Q2, the third switching device Q5, the fourth switching device Q6, and the fifth switching device Q3 are turned off, so that the first heating element 41 has current flowing from the first terminal 43 to the connection terminal 45. The control circuit 30 can also control the second switching device Q2 and the fifth switching device Q3 to be turned on, while the first switching device Q1, the third switching device Q5, the fourth switching device Q6, and the sixth switching device Q4 are turned off, so that the first heating element 41 has current flowing from the connection terminal 45 to the first terminal 43. The control circuit 30 can selectively or periodically control the current direction, for example, changing the current direction once every 0.1s, 0.2s, or 0.3s, or any other time, which is not limited here. In some embodiments, a first time threshold can be set in the processor, causing the control circuit 30 to control the current direction of the first heating element 41 to change once within the first time threshold. In some embodiments, the time of the first time threshold can be 0.1s, 0.2s, or 0.3s, or other times, which are not limited here.
[0065] Understandably, the control circuit 30 can control the third switch Q5 and the sixth switch Q4 to be turned on, while the first switch Q1, the second switch Q2, the fourth switch Q6, and the fifth switch Q3 are turned off, so that the second heating element 42 has current flowing from the second terminal 44 to the connection terminal 45. The control circuit 30 can also control the fourth switch Q6 and the fifth switch Q3 to be turned on, while the first switch Q1, the second switch Q2, the third switch Q5, and the sixth switch Q4 are turned off, so that the second heating element 42 has current flowing from the connection terminal 45 to the second terminal 44. The control circuit 30 can selectively or periodically control the current direction, for example, changing the current direction once every 0.1s, 0.2s, or 0.3s, or any other time, which is not limited here. In some embodiments, a second time threshold can be set in the processor, causing the control circuit 30 to control the current direction of the second heating element 42 to change once within the second time threshold.

[0067] Changing the direction of the current can alter the electric field around the heating element, effectively preventing carbon buildup on the heating element that could affect the atomization device's flavor. It can also extend the lifespan of the heating element and improve the user experience.
[0068] In some embodiments, selectively controlling the current direction may refer to the atomizing device 100 having a flavor or texture selection function. Each different flavor or texture corresponds to a different current control logic or current direction control logic of the heating control circuit 101. That is, different current control logics or current direction control logics can cause the atomizing device 100 to produce different flavors or textures. Users can select flavors or textures according to their needs, i.e., the atomizing device 100 can selectively control the current direction. In some embodiments, periodically controlling the current direction may refer to the atomizing device 100 being provided with a computer-readable storage medium storing a computer program that is configured to cause the heating control circuit 101 to periodically control the current direction for heating.

[0070] In some embodiments, the resistance values of the gate pull-down resistors R1, R4, R5, R8, R9, and R12 can be 100,000 ohms, and the specific resistance values are not limited here.
[0071] Please refer to Figure 4, which is a partial circuit diagram of the detection circuit in some embodiments of the embodiment shown in Figure 1. The detection circuit 102 can be electrically connected to the heating control circuit 101 and can be used to detect the voltage of the heating control circuit 101 and the resistance of the heating circuit 40, such as the heating element, when it is working. In this way, it can cooperate with the control circuit 30 to control the power of the heating circuit 40, such as the heating element. In some embodiments, the detection circuit 102 can be part of the heating circuit 40.
[0072] The detection circuit 102 can be electrically connected to the power supply circuit 10 to detect electrical parameters such as voltage, resistance, current, and temperature of the power supply circuit 10 and the heating elements, such as the first heating element 41 and the second heating element 42. The control circuit 30 can be electrically connected to the detection circuit 102 to receive the electrical parameters. The control circuit 30 can send signals to the switching circuit 20 according to the electrical parameters to control the on and off of each switching device. By controlling the coordinated operation of each switching device, the working state of the heating elements, such as the first heating element 41 and the second heating element 42, can be controlled, thereby adjusting the flavor of the atomizing device 100.
[0073] The detection circuit 102 may include a resistance detection circuit 1021, which may be electrically connected to the power supply circuit 10, the switching circuit 20, and the control circuit 30. The resistance detection circuit 1021 is used to detect the resistance of the first heating element 41 and / or the second heating element 42 when they are working, thereby obtaining the operating power of the first heating element 41 and / or the second heating element 42 through the processor in the control circuit 30, and then controlling the operating power of the heating elements, such as the first heating element 41 and the second heating element 42.
[0074] In some embodiments, the resistance detection circuit 1021 can be used to detect the resistance of the first heating element 41 and / or the second heating element 42, and transmit the data to the control circuit 30.
[0075] In some embodiments, the heating control circuit 101 may have three resistance detection circuits 1021: one connected in series between the power supply circuit 10 and the first terminal 43, one connected in series between the power supply circuit 10 and the second terminal 44, and one connected in series between the power supply circuit 10 and the connection terminal 45. In some embodiments, the heating control circuit 101 may also have two resistance detection circuits 1021, which may be connected in series between two of the following: the power supply circuit 10 and the first terminal 43, the power supply circuit 10 and the second terminal 44, or the power supply circuit 10 and the connection terminal 45. In some embodiments, the heating control circuit 101 may also have one resistance detection circuit 1021, which may be connected in series between the power supply circuit 10 and the first terminal 43, the power supply circuit 10 and the second terminal 44, or the power supply circuit 10 and the connection terminal 45.
[0076] The signal output terminal of the resistance detection circuit 1021 is electrically connected to the control circuit 30, so that the data of the resistance detection circuit 1021 can be transmitted to the processor.
[0077] The resistance detection circuit 1021 may include a non-inverting amplifier U1, a voltage regulator capacitor C1, a feedback resistor R13, a current-limiting resistor R14, a gain resistor R15, and a current sampling resistor R16. The voltage regulator capacitor C1 is connected in series between the high-level terminal VBAT and the ground terminal GND to stabilize the operating voltage of the non-inverting amplifier U1. The non-inverting amplifier U1 processes the voltage at the low-level terminal F GND in the switching circuit 20, converting the voltage output from the low-level terminal F GND into an F ADC voltage signal that can be processed by the control circuit 30, such as a processor. The non-inverting amplifier U1 has a non-inverting input terminal 1023, an inverting input terminal 1024, and an output terminal F ADC. The non-inverting input terminal 1023 is electrically connected to the low-level terminal F GND in the switching circuit 20 and is used to read the voltage signal at the low-level terminal F GND in the switching circuit 20. A current-limiting resistor R14 is connected in series between the non-inverting input terminal 1023 and the low-level terminal F (GND) in the switching circuit 20 to control the current at the non-inverting input terminal 1023. The inverting input terminal 1024 is connected to ground (GND), and a gain resistor R15 is connected in series between the inverting input terminal 1024 and ground (GND). The output terminal F (ADC) is electrically connected to the control circuit 30 and can be used to output an ADC signal usable by, for example, a processor. A feedback resistor R13 is connected in series between the inverting input terminal 1024 and the output terminal. The feedback resistor R13, in conjunction with the gain resistor R15, determines the amplification factor of the non-inverting proportional amplifier circuit.
[0078] The formula for calculating the voltage at the output terminal F of the ADC is as follows: .
[0079] The current sampling resistor R16 is connected in series between the low-level terminal F GND and the ground terminal GND in the switching circuit 20, and can be used to measure the operating current of the heating element.
[0080] Formula for calculating the operating current of a heating element: .
[0081] Where: n is the voltage amplification factor, .
[0082] Furthermore, under normal operating conditions, the resistance of the six switching devices is very small when they are turned on, and the resistance of the current sampling resistor R16 is also small, so their resistance values can be ignored, and the voltage drop across them can also be ignored. Therefore, the heating power and equivalent resistance of the heating element can be calculated based on the operating current and voltage of the heating element.
[0083] Formula for calculating the heating power of a heating element: .
[0084] Formula for calculating the equivalent resistance of a heating element: .
[0085] Furthermore, when the atomizing device 100 is working, the control circuit 30, such as the processor, can obtain the voltage signal of the output terminal F ADC. The control circuit 30, such as the processor, can calculate the specific resistance value of the heating element. If the value is within the range set by the control circuit 30, such as the processor, it can operate normally. If it is not within the range, it will stop working and simultaneously issue an alarm.
[0086] Furthermore, by comparing the control circuit 30 with preset values within the processor, the duty cycle of the control signal can be adjusted, and the output power can be adjusted in real time.
[0087] In some embodiments, the heating element, such as the first heating element 41 and the second heating element 42, can be a heating element whose resistance is greatly affected by temperature, such as nickel 200, 316 stainless steel, or titanium alloy. Alternatively, the current operating temperature of the heating element can be obtained by the control circuit 30, such as the temperature coefficient of resistance (TCR) curve of the heating element pre-stored in the processor. The atomization temperature can also be controlled by this circuit.
[0088] Please refer to Figure 5, which is a partial circuit diagram of the detection circuit in some embodiments of the embodiment shown in Figure 1. The detection circuit 102 may further include a voltage detection circuit 1022, one end of which is connected to the power supply circuit 10, and the other end is connected to the processor in the control circuit 30. It is used to detect the voltage applied by the power supply circuit 10 to the first heating element 41 and / or the second heating element 42. The control circuit 30 is configured to determine the atomization temperature based on resistance. In some embodiments, the voltage detection circuit 1022 can be used to monitor the power supply voltage in real time to ensure that the atomizing device 100 operates under normal voltage.
[0089] A voltage detection circuit 1022 is connected in series between the current output terminal and the current input terminal of the power supply circuit 10, and includes an upper resistor R17 and a lower resistor R18 connected in series. The connection point of the upper resistor R17 and the lower resistor R18 is electrically connected to the control circuit 30, allowing the processor to obtain the operating voltage of the heating element and also protecting the heating control circuit 101. It is understood that the voltage detection circuit 1022 may include an upper resistor R17 and a lower resistor R18. The upper resistor R17 is connected between the high-level terminal VBAT and the output terminal VBAT ADC. The upper resistor R17 can be used to bear most of the voltage drop of the power supply voltage, limiting the current flowing into the processor, thus playing a protective and current-limiting role. The lower resistor R18 is connected between the ground terminal GND and the output terminal VBAT ADC, and can be used to establish a voltage divider reference point.
[0090] The formula for calculating the voltage output to the processor is as follows: .
[0091] In some embodiments, the detection circuit 102 may include three sub-detection circuits. The input terminal F GND of the first sub-detection circuit is electrically connected to the low-level terminal F GND of the first sub-switch circuit 21. The input terminal F GND of the second sub-detection circuit is electrically connected to the low-level terminal F GND of the second sub-switch circuit 22. The input terminal F GND of the third sub-detection circuit is electrically connected to the low-level terminal F GND of the third sub-switch circuit 23.
[0092] Please refer to Figures 6, 7, and 8. Figure 6 is a structural schematic diagram of the atomizing device in the embodiment shown in Figure 1; Figure 7 is a cross-sectional schematic diagram of the atomizing device in the embodiment shown in Figure 6; and Figure 8 is a structural schematic diagram of the two heating elements of the atomizing device 100 in the embodiment shown in Figure 7. The atomizing device 100 may have a nozzle 1001 and a housing 1002, with the nozzle 1001 disposed on the housing 1002. The first heating element 41 and the second heating element 42 may be disposed within the housing 1002 for heating the atomizing substrate.
[0093] The atomizing device 100, for example, has an aerosol flow channel 1003 inside the housing 1002. One end of the aerosol flow channel 1003 may form a nozzle 1001 on the surface of the housing 1002.
[0094] The first heating element 41 and the second heating element 42 can be disposed in the aerosol flow channel 1003, so that the aerosol after heating and atomizing the matrix can remain in the aerosol flow channel 1003. In some embodiments, the first heating element 41 and the second heating element 42 can be arranged in the extending direction of the aerosol flow channel 1003. The aerosol formed by the heating of the first heating element 41 and the second heating element 42 can be inhaled by the user through the aerosol flow channel 1003. In some embodiments, one end of the aerosol flow channel 1003 can be connected to the outside, so that when the user inhales at the nozzle 1001, outside air can enter the aerosol flow channel 1003, mix with the aerosol, and be inhaled by the user.
[0095] In some embodiments, the first heating element 41 is closer to the outlet 1004 of the aerosol flow channel 1003 at the nozzle 1001 than the second heating element 42. The first heating element 41 may have a first electrode 401, and a first end 43 may be connected to the first electrode 401. Of course, in other embodiments, the first electrode 401 may also serve as the first end 43.
[0096] The second heating element 42 may have a second electrode 402, and the second end 44 may be connected to the second electrode 402. Of course, in other embodiments, the second electrode 402 may also serve as the second end 44.
[0097] The first heating element 41 and the second heating element 42 share a common intermediate electrode 403, and the connection end 45 can be connected to the intermediate electrode 403. Of course, in other embodiments, the intermediate electrode 403 can also be used as the connection end 45.
[0098] Please refer to Figures 9 and 10. Figure 9 is a cross-sectional schematic diagram of another atomizing device in the embodiment shown in Figure 6, and Figure 10 is a structural schematic diagram of the heating element of the atomizing device in the embodiment shown in Figure 9. One end of the heating element 200 can be connected to the first electrode 501, that is, the first end 53 can be connected to the first electrode 501. Of course, in other embodiments, the first electrode 501 can also be used as the first end 53.
[0099] The other end of the heating element 200 can be connected to the second electrode 502, that is, the second end 54 can be connected to the second electrode 502. Of course, in other embodiments, the second electrode 502 can also be used as the second end 54.
[0100] The middle part of the heating element 200 can be connected to the intermediate electrode 503, that is, the connection end 55 can be connected to the intermediate electrode 503. Of course, in other embodiments, the intermediate electrode 503 can also be used as the connection end 55.
[0101] Understandably, the intermediate electrode can divide the heating element 200 into a first heating element 51 and a second heating element 52. The first heating element 51 and the second heating element 52 can be arranged in a direction perpendicular to the extending direction of the aerosol flow channel 1003. The aerosol formed by the heating of the first heating element 51 and the second heating element 52 can be inhaled by the user through the aerosol flow channel 1003.
[0102] In some embodiments, the distances between the two heating elements and the nozzle 1001 may be the same or different. In some embodiments, the heating element 200 may be a mesh structure, but other structures are also possible, which will not be elaborated here. In some embodiments, the first heating element 41 and the second heating element 42 may both be mesh structures, but other structures are also possible, which will not be elaborated here.
[0103] This application further provides an atomization control method, which can be used to control the aforementioned atomizing device 100 and can be executed by a control circuit 30, such as a processor. The atomization control method mainly involves the processor in the control circuit 30 sending control signals to the switching circuit 20, thereby controlling the switching circuit 20 to switch on and off, for example, six switching devices (i.e., first switching device Q1, second switching device Q2, third switching device Q5, fourth switching device Q6, fifth switching device Q3, and sixth switching device Q4), to control the operating state of the heating circuit 40, such as the first heating element 41 and the second heating element 42. By controlling the heating circuit 40, such as the first heating element 41 and the second heating element 42, through the control circuit 30, the flavor of the atomizing device 100 can be adjusted, improving the user experience. Furthermore, the coordinated operation of the two heating elements, such as the first heating element 41 and the second heating element 42, can reduce surface carbon buildup on the heating elements, and also extend their service life.
[0104] By coordinating the various switching devices, the atomizing device 100 can operate in multiple states. In some scenarios, the first heating element 41 can operate independently while the second heating element 42 remains inactive. In other scenarios, the second heating element 42 can operate independently while the first heating element 41 remains inactive. In some scenarios, the first heating element 41 and the second heating element 42 can operate in series. In still other scenarios, the first heating element 41 and the second heating element 42 can operate in parallel. Each operating state results in a different degree of heating of the atomizing substrate, thus enabling the atomizing device 100 to achieve different inhalation sensations.
[0105] Specifically, in some scenarios, the control circuit 30 can control the first heating element 41 to operate independently. The control circuit 30 can send a signal to the control signal output terminal F1 DRV P of the first sub-circuit 31, causing the first switching device Q1 to conduct. The control circuit 30 can also send a signal to the control signal output terminals F1-F2 DRV N of the sixth sub-circuit 36, causing the sixth switching device Q4 to conduct. This allows the first terminal 43 of the first heating element 41 to be electrically connected to the high-level terminal VBAT, and the connection terminal 45 to be electrically connected to the low-level terminal F GND. At this time, the first heating element 41 has current flowing from the first terminal 43 to the connection terminal 45. In some scenarios, the control circuit 30 can send a signal to the control signal output terminals F1-F2 DRV P of the fifth sub-circuit 35, causing the fifth switching device Q3 to conduct. The control circuit 30 can also send a signal to the control signal output terminal F1 DRV N of the second sub-circuit 32, causing the second switching device Q2 to conduct. This allows the first heating element 41 to be electrically connected at connection terminal 45 to the high-level terminal VBAT, and at first terminal 43 to the low-level terminal F GND. At this time, the first heating element 41 has current flowing from connection terminal 45 to first terminal 43.
[0106] Understandably, the first sub-switch circuit 21 and the third sub-switch circuit 23 work together to reverse the current when the first heating element 41 works alone, thereby delaying the accumulation of carbides on the surface of the first heating element 41.
[0107] In some scenarios, control circuit 30 can control the second heating element 42 to operate independently. Control circuit 30 can send a signal to the control signal output terminal F2 DRV P of the third sub-circuit 33, causing the third switching device Q5 to conduct. Control circuit 30 can send a signal to the control signal output terminals F1-F2 DRV N of the sixth sub-circuit 36, causing the sixth switching device Q4 to conduct. This allows the second terminal 44 of the second heating element 42 to be electrically connected to the high-level terminal VBAT, and the connection terminal 45 to be electrically connected to the low-level terminal F GND. At this time, the second heating element 42 has current flowing from the first terminal 43 to the connection terminal 45. Understandably, control circuit 30 can send a signal to the control signal output terminals F1-F2 DRV P of the fifth sub-circuit 35, causing the fifth switching device Q3 to conduct. Control circuit 30 can send a signal to the control signal output terminal F2 DRV N of the fourth sub-circuit 34, causing the fourth switching device Q6 to conduct. This allows the second heating element 42 to be electrically connected at connection terminal 45 to the high-level terminal VBAT, and at connection terminal 44 to the low-level terminal F GND. At this time, the second heating element 42 has current flowing from connection terminal 45 to terminal 44. It is understandable that the second sub-switch circuit 22, in conjunction with the third sub-switch circuit 23, can redirect the current when the second heating element 42 operates alone, thereby delaying the accumulation of carbides on the surface of the second heating element 42.
[0108] In some embodiments, the first heating element 41 can be controlled to heat up alone first, followed by the second heating element 42. In some embodiments, the second heating element 42 can be controlled to heat up alone first, followed by the first heating element 41 operating alone. In some embodiments, the first heating element 41 and the second heating element 42 can be controlled to heat alternately. The heating time of the first heating element 41 and the second heating element 42 can be controlled to be equal, or the heating time of the first heating element 41 and the second heating element 42 can be controlled to be unequal.
[0109] In some scenarios, the control circuit 30 can control the first heating element 41 and the second heating element 42 to operate in parallel. The control circuit 30 can send a signal to the control signal output terminal F1 DRV P of the first sub-circuit 31, causing the first switching device Q1 to conduct. Simultaneously, the control circuit 30 can send a signal to the control signal output terminal F2 DRV P of the third sub-circuit 33, causing the third switching device Q5 to conduct. The control circuit 30 can also send a signal to the control signal output terminals F1-F2 DRV N of the sixth sub-circuit 36, causing the sixth switching device Q4 to conduct. This allows the first terminal 43 of the first heating element 41 to be electrically connected to the high-level terminal VBAT, the second terminal 44 of the second heating element 42 to be electrically connected to the high-level terminal VBAT, and the connection terminal 45 to be electrically connected to the low-level terminal F GND. At this time, the first heating element 41 has current flowing from its first terminal 43 to the connection terminal 45, and simultaneously, the second heating element 42 also has current flowing from its first terminal 43 to the connection terminal 45. Understandably, control circuit 30 can send a signal to the control signal output terminals F1-F2 DRV P of the fifth sub-circuit 35, causing the fifth switching device Q3 to conduct. Control circuit 30 can also send a signal to the control signal output terminal F1 DRV N of the second sub-circuit 32, causing the second switching device Q2 to conduct. Simultaneously, control circuit 30 can send a signal to the control signal output terminal F2 DRV N of the fourth sub-circuit 34, causing the fourth switching device Q6 to conduct. This allows the connection terminal 45 of the first heating element 41 and the second heating element 42 to be electrically connected to the high-level terminal VBAT, the first terminal 43 of the first heating element 41 to be electrically connected to the low-level terminal F GND, and the second terminal 44 of the second heating element 42 to be electrically connected to the low-level terminal F GND. At this time, the first heating element 41 has current flowing from the connection terminal 45 to the first terminal 43, and simultaneously, the second heating element 42 also has current flowing from the connection terminal 45 to the second terminal 44. Understandably, the first sub-switch circuit 21, the second sub-switch circuit 22, and the third sub-switch circuit 23 work together to enable the first heating element 41 and the second heating element 42 to operate in parallel. They can also reverse the operating current of the first heating element 41 and the second heating element 42, thereby delaying the accumulation of carbides on the surfaces of the first heating element 41 and the second heating element 42.
[0110] In some embodiments, the first heating element 41 or the second heating element 42 can be controlled to heat individually first, and then the first heating element 41 and the second heating element 42 can be controlled to heat in parallel. In some embodiments, the first heating element 41 and the second heating element 42 can be controlled to heat in parallel first, and then the first heating element 41 or the second heating element 42 can be controlled to heat individually. In some embodiments, the two heating states of the first heating element 41 or the second heating element 42 heating individually and the first heating element 41 and the second heating element 42 heating in parallel can be alternated, and the heating time of the first heating element 41 or the second heating element 42 heating individually and the first heating element 41 and the second heating element 42 heating in parallel can be equal or unequal.
[0111] In some scenarios, the control circuit 30 can control the first heating element 41 and the second heating element 42 to operate in series. The control circuit 30 can send a signal to the control signal output terminal F1 DRV P of the first sub-circuit 31, causing the first switching device Q1 to conduct. The control circuit 30 can send a signal to the control signal output terminal F2 DRV N of the fourth sub-circuit 34, causing the fourth switching device Q6 to conduct. This allows the first terminal 43 of the first heating element 41 to be electrically connected to the high-level terminal VBAT, and the second terminal 44 of the second heating element 42 to be electrically connected to the low-level terminal F GND. At this time, the first heating element 41 has current flowing from its first terminal 43 to the connection terminal 45, and the second heating element 42 has current flowing from the connection terminal 45 to its first terminal 43. It is understandable that the control circuit 30 can send a signal to the control signal output terminal F2 DRV P of the third sub-circuit 33, causing the third switching device Q5 to conduct. The control circuit 30 can send a signal to the control signal output terminal F1 DRV N of the second sub-circuit 32, causing the second switching device Q2 to conduct. This allows the second terminal 44 of the second heating element 42 to be electrically connected to the high-level terminal VBAT, and the first terminal 43 of the first heating element 41 to be electrically connected to the low-level terminal F GND. At this time, the second heating element 42 has current flowing from its second terminal 44 to the connection terminal 45, and the first heating element 41 has current flowing from the connection terminal 45 to its first terminal 43. It is understandable that the first sub-switch circuit 21 and the second sub-switch circuit 22, in conjunction, can enable the first heating element 41 and the second heating element 42 to operate in series. It can also reverse the operating current of the first heating element 41 and the second heating element 42, thereby delaying the accumulation of carbides on the surfaces of the first heating element 41 and the second heating element 42.
[0112] In some embodiments, the first heating element 41 or the second heating element 42 can be controlled to heat individually first, and then the first heating element 41 and the second heating element 42 can be controlled to heat in parallel or in series. In some embodiments, the first heating element 41 and the second heating element 42 can be controlled to heat in parallel or in series first, and then the first heating element 41 or the second heating element 42 can be controlled to heat individually. In some embodiments, the two heating states of the first heating element 41 or the second heating element 42 heating individually and the first heating element 41 and the second heating element 42 heating in parallel or in series can be alternated, and the heating time of the first heating element 41 or the second heating element 42 heating individually and the first heating element 41 and the second heating element 42 heating in parallel or in series can be equal or unequal. It can be understood that by controlling the six switches in the three sub-switch circuits to cooperate with each other, the heating mode can be diversified, so that the atomizing device can have a rich flavor.
[0113] Please refer to Figure 11, which is a schematic flowchart of the atomization control method in some embodiments of this application. An atomization control method may include: Step S101: controlling the second heating element to heat for a first heating duration within at least one first suction cycle.
[0114] Step S102: Control the first heating element and the second heating element to be connected in parallel during at least one first suction cycle, and heat for a second heating duration.
[0115] In step S101, a first suction cycle can be 1.6 seconds. Of course, other durations are also possible, such as 1 second or 2 seconds, and are not limited here. In some embodiments, the current direction of the first heating element 41 and the second heating element 42 changes once within a first suction cycle, for example, after half a suction cycle. In some embodiments, the current direction of the first heating element 41 and the second heating element 42 changes two, three, or even more times within a suction cycle. Of course, the current direction can remain unchanged within a suction cycle and change upon entering the next suction cycle. The first heating duration can be shorter than the first suction cycle duration; the first heating duration can be 0.1 seconds or 0.2 seconds, and of course, other durations are also possible, and are not limited here. In some embodiments, the current direction of the first heating element 41 and the second heating element 42 changes once, twice, or even more times within a heating duration; of course, the current direction can remain unchanged within a heating duration and change upon entering the next heating duration. The change in current direction can delay carbon buildup on the surface of the heating element and extend the service life of the atomizing device 100.
[0116] In step S102, the second heating duration may be the same as or different from the first heating duration, which will not be elaborated here. It is understood that the heating durations of the first heating element 41 and the second heating element 42 can be adjusted according to user needs.
[0117] As can be understood, referring again to Figures 7 and 8, in some embodiments, the first heating element 41 and the second heating element 42 are disposed within the aerosol flow channel 1003 and arranged in the direction of the aerosol flow channel 1003. Compared to the second heating element 42, the first heating element 41 is closer to the outlet 1004 of the aerosol flow channel 1003. When the atomizing device 100 is working, the second heating element 42 can first heat the atomizing matrix to form an aerogel during the first heating period, at which time the atomizing matrix is not completely atomized. Since the first heating element 41 is closer to the nozzle 1001 in the aerosol flow channel 1003, the first heating element 41 can reheat the aerogel formed by the second heating element 42, at which time the atomizing matrix is completely atomized.
[0118] In some embodiments, the first heating element 41 and the second heating element 42 are arranged side by side in the vertical direction, and both the first heating element 41 and the second heating element 42 are mesh structures.
[0119] In some embodiments, before step S101 is performed, step S100 can be performed first: controlling the first heating element 41 and the second heating element 42 to be connected in series for heating.
[0120] Understandably, the heating power of the first heating element 41 and the second heating element 42 connected in series is lower. When the user inhales the atomizing device 100, the control circuit 30 can control the first heating element 41 and the second heating element 42 to be connected in series for preheating. This results in a better taste on the first puff and improves the user experience. Understandably, when the atomizing device 100 is not in the first puff cycle, but in the second puff cycle or between other puff cycles, controlling the first heating element 41 and the second heating element 42 in series is for heat preservation, resulting in a better taste from the atomizing device 100.
[0121] In some embodiments, the power of the second heating element 42 for heating the first heating duration is controlled to be different in different vaping cycles, and / or the duration of the first heating duration is controlled to be different in different vaping cycles. It is understood that by controlling the heating power of the second heating element 42 and the duration of the first heating duration, the atomization degree of the atomizing matrix can be made different, resulting in different tastes, thereby achieving flavor adjustment.
[0122] After step S102 is performed, step S103 can be continued: controlling the heating of the first heating element 41 for a third heating duration within at least one first suction cycle.
[0123] In some embodiments, the power of the first heating element 41 for heating the third heating duration is controlled to be different in different suction cycles, and / or the duration of the third heating duration is controlled to be different in different suction cycles. It is understood that changing the heating power of the first heating element 41 and the duration of the third heating duration in each suction cycle can make the suction more layered and improve the user experience.
[0124] After step S103 is performed, step S104 can be continued: controlling the second heating element 42 to heat for a fourth heating duration within at least one first suction cycle.
[0125] In some embodiments, the power of the second heating element 42 for heating the fourth heating duration varies in different suction cycles. It is understood that changing the heating power of the second heating element 42 and the duration of the fourth heating duration within each suction cycle can make the suction more layered and improve the user experience.
[0126] Understandably, the order of steps S101, S102, S103, and S104 can be changed, repeated, or adjusted according to user needs. In some embodiments, the atomizing device 100 may have a flavor selection function. The processor can send a control signal according to the flavor selected by the user, thereby controlling the working state of the first heating element 41 and the second heating element 42 to achieve flavor adjustment of the atomizing device 100.
[0127] In some embodiments, the first heating element 41 and the second heating element 42 may perform steps S101, S102, S103 and S104 in the structure shown in FIG7 and FIG8.
[0128] Please refer to Figure 12, which is a schematic flowchart of the atomization control method in some embodiments of this application. An atomization control method further includes: step S201: controlling the first heating element to heat for a first heating duration within at least one second suction cycle.
[0129] Step S202: Control the first heating element and the second heating element to be connected in parallel during at least one second suction cycle, and heat for a second heating duration.
[0130] In step S201, the duration of the second suction cycle may be equal to or different from that of the first suction cycle, which will not be elaborated here. The logic for changing the current direction may also be the same as or different from that of the first suction cycle, which will not be elaborated here.
[0131] In some embodiments, the power of the first heating element 41 for heating the first heating duration is controlled to be different in different suction cycles, and / or the duration of the first heating duration is controlled to be different in different suction cycles. It is understood that the flavor can be controlled by controlling the heating power of the first heating element 41 and the duration of the first heating duration, thereby producing different tastes and achieving flavor adjustment.
[0132] After step S202 is performed, step S203 can be continued: controlling the second heating element 42 to heat for a third heating duration within at least one second suction cycle.
[0133] In some embodiments, the power of the second heating element 42 for heating the third heating duration is controlled to be different in different suction cycles, and / or the duration of the third heating duration is controlled to be different in different suction cycles. It is understood that changing the heating power of the second heating element 42 and the duration of the third heating duration in each suction cycle can make the suction more layered and improve the user experience.
[0134] After step S203 is performed, step S204 can be continued: controlling the first heating element 41 to heat for a fourth heating duration within at least one second suction cycle.
[0135] In some embodiments, the power of the first heating element 41 for heating the fourth heating duration varies in different suction cycles. It is understood that changing the heating power of the first heating element 41 and the duration of the fourth heating duration within each suction cycle can make the suction more layered and improve the user experience.
[0136] Understandably, the order of steps S201, S202, S203, and S204 can be changed or repeated, and can be adjusted according to user needs. The heating method of the second inhalation cycle can be different from that of the first inhalation cycle, so that the taste of each inhalation cycle is different, giving the atomizing device 100 a richer taste.
[0137] In some embodiments, the first heating element 41 and the second heating element 42 may perform steps S201, S202, S203 and S204 in the structure shown in FIG7 and FIG8.
[0138] In some embodiments, the continuous heating duration of the first heating element 41 and / or the second heating element 42 is controlled to be less than or equal to a first time threshold. The heating temperature of the first heating element 41 within the first time threshold is less than the highest temperature of the first heating element 41. The heating temperature of the second heating element 42 within the first time threshold is less than the highest temperature of the second heating element 42. It is understood that the processor determines the heating temperatures of the first heating element 41 and the second heating element 42 based on data input from the voltage detection circuit 1022 and the resistance detection circuit 1021. This allows control of the first heating element 41 and the second heating element 42 during the heating process to ensure they do not exceed the temperature set by the processor. This avoids excessively high heating element temperatures leading to the accumulation of carbon deposits on the surface of the heating elements, prevents a burnt smell after a period of use, and extends the service life of the heating elements.
[0139] In some embodiments, the atomizing device 100 may also be provided with a temperature sensor, and the processor can receive the signal from the temperature sensor to determine the heating temperature of the first heating element 41 and the second heating element 42. In some embodiments, the atomizing device 100 may also obtain the temperature of the first heating element 41 and the second heating element 42 through a thermistor.
[0140] In some embodiments, the maximum temperature may refer to the temperature of the two heating elements at their rated power when operating in series, parallel, or individually. In some embodiments, to prevent the atomizing device from producing a burnt taste and to achieve a better mouthfeel and flavor, the operating temperature of the heating elements can be controlled between 180 degrees Celsius and 240 degrees Celsius, and thus the maximum temperature can be 240 degrees Celsius. Of course, those skilled in the art can choose the maximum temperature setting according to actual needs, and this application does not impose any restrictions on it.
[0141] In some embodiments, the duration for which the current flow direction on the first heating element 41 and / or the second heating element 42 remains constant is less than or equal to a second time threshold. The heating temperature of the first heating element 41 within the second time threshold is less than the highest temperature of the first heating element 41. The heating temperature of the second heating element 42 within the second time threshold is less than the highest temperature of the second heating element 42. It is understood that the current direction of the first heating element 41 and / or the second heating element 42 will change once within a duration less than or equal to the second time threshold. This change in current direction can alter the direction of the electric field formed by the heating element, reducing localized carbon buildup and increasing the lifespan of the heating element. It can also ensure uniform heat distribution, reducing excessively high temperatures, especially at the connection points, effectively preventing carbon deposits from accumulating at both ends of the heating element and extending the atomizer's lifespan.
[0142] This application provides a specific implementation example, as shown in Table 1.
[0143] Table 1: Control Logic Table for Heating Components of Atomizing Device
[0144] As shown in Table 1, in the implementation example, the first heating element 41 and the second heating element 42 are arranged in the aerosol flow channel 1003 and are arranged in the direction of the aerosol flow channel 1003. Compared with the second heating element 42, the first heating element 41 is closer to the outlet 1004 of the aerosol flow channel 1003.
[0145] During the first heating cycle (0-0.2s), the second heating element 42 is heated independently with an 8W power output. During the first heating cycle (0.2-0.4s), the second heating element 42 is heated independently with an 8W power output. During the first heating cycle (0.4-0.6s), the first heating element 41 is heated together with an 10W power output and the second heating element 42 with an 8W power output. During the first heating cycle (0.6-0.8s), the first heating element 41 is heated together with an 10W power output and the second heating element 42 with an 8W power output. During the first heating cycle (0.8-1s), the first heating element 41 is heated independently with an 10W power output. During the first heating cycle (1-1.2s), the first heating element 41 is heated independently with an 10W power output. During the first heating cycle (1.2-1.4s), the second heating element 42 is heated independently with an 8W power output. During the first heating cycle (1.4-1.6s), the second heating element 42 is heated independently with an 8W power output. Understandably, in the implementation example shown in Table 1, one suction cycle is 1.6s. Within one suction cycle, the first heating element 41 and the second heating element 42 can be controlled to heat separately, or the first heating element 41 and the second heating element 42 can be controlled to heat together, and the heating power of each heating element can also be controlled.
[0146] In some embodiments, the direction of the current in the heating element may change once every 0.1s or once every 0.2s, and no specific limitation is made here.
[0147] During the second heating cycle (0-0.2s), the second heating element 42 is heated independently with a power of 10W. During the second heating cycle (0.2-0.4s), the second heating element 42 is heated independently with a power of 10W. During the second heating cycle (0.4-0.6s), the first heating element 41 is heated together with a power of 8W and the second heating element 42 with a power of 10W. During the second heating cycle (0.6-0.8s), the first heating element 41 is heated together with a power of 8W and the second heating element 42 with a power of 10W. During the second heating cycle (0.8-1s), the first heating element 41 is heated independently with a power of 8W. During the second heating cycle (1-1.2s), the first heating element 41 is heated independently with a power of 8W. During the second heating cycle (1.2-1.4s), the second heating element 42 is heated independently with a power of 10W. During the second heating cycle (1.4-1.6s), the second heating element 42 is heated independently with a power of 10W. Understandably, by controlling the different heating power of the first heating element 41 and the second heating element 42 at each time period within a vaping cycle, the flavor profile of the atomizing device 100 can be altered, providing users with a better experience.
[0148] As shown in Table 1, the third to eighth inlets all utilize different control logics to control the heating power of the first heating element 41 and the second heating element 42 at different times, thereby altering the flavor profile of the atomizer. These details will not be elaborated upon here. Of course, the control logic of this application is not limited to the implementation examples shown in Table 1.
[0149] Referring again to Figures 9 and 10, in some embodiments, the first heating element 51 and the second heating element 52 are disposed within the aerosol flow channel 1003 and arranged in a direction perpendicular to the extending direction of the aerosol flow channel 1003. It is understood that the first heating element 51 and the second heating element 52 have different operating power when connected in series and in parallel, and the taste of the atomizing device 100 can be changed by altering the heating state.
[0150] Understandably, the first heating element 51 and the second heating element 52 are installed at the same horizontal height. The first heating element 51 and the second heating element 52 work at the same time, which can keep the local temperature of the atomizing device 100 in a higher range, increase the atomization amount of the atomizing matrix, and meet the needs of users with large amounts of smoke.
[0151] In some embodiments, the first heating element 51 and the second heating element 52 are arranged side by side in the horizontal direction, and both the first heating element 51 and the second heating element 52 are mesh structures.
[0152] In some embodiments, the first heating element 51 and the second heating element 52 can respectively heat atomizing substrates with different flavors. After being heated separately, the two atomizing substrates can be mixed in the aerosol flow channel 1003 and inhaled together by the user. By controlling the heating power of the heating elements, the concentration of the aerosol formed by the atomizing substrates heated by the first heating element 51 and the second heating element 52 can be controlled, thereby changing the flavor profile of the mixed aerosol and improving the user experience.
[0153] Please refer to Figure 13, which is a schematic flowchart of the atomization control method in some embodiments of this application. An atomization control method includes: Step S301: Controlling a first heating element 51 and a second heating element 52 in series for heating during at least one first suction cycle.
[0154] Step S302: Control the first heating element 51 and the second heating element 52 to heat up separately and sequentially during at least one first suction cycle.
[0155] Step S303: Control the first heating element 51 and the second heating element 52 to be connected in parallel during at least one first suction cycle for heating.
[0156] Understandably, in the first inhalation cycle, the first heating element 51 and the second heating element 52 can be controlled to work in series for preheating. In the first inhalation cycle, the first heating element 51 and the second heating element 52 can be controlled to slowly heat up separately. In the first inhalation cycle, the first heating element 51 and the second heating element 52 can also be controlled to work in parallel for fast heating. This allows the atomizing device 100 to have a rich flavor profile in the first inhalation cycle, thus improving the user experience.
[0157] After step S303, step S304 can be continued: within at least one first suction cycle, the first heating element 51 and the second heating element 52 are controlled to heat independently and sequentially. Understandably, either the first heating element 51 or the second heating element 52 can be selected for heating. The two heating elements produce different atomized matrix flavors, allowing users to choose the flavor according to their needs and providing a different experience.
[0158] In some embodiments, a first suction cycle includes a first cycle and a second cycle. The duration of the first cycle may be equal to or unequal to the duration of the second cycle, and this is not limited here. In some embodiments, the duration of the first cycle and the duration of the second cycle may be 0.1s, 0.2s, or other durations, and this is not limited here. Of course, the first suction cycle may also include a third cycle or more, and this is not limited here.
[0159] In some embodiments, the first cycle and the second cycle can also be controlled to change the current direction within the cycle, just like the first suction cycle described above, which will not be elaborated here.
[0160] Step S302 may include steps S3021 and S3022. Step S3021: During the first cycle, the first heating element 51 and the second heating element 52 are controlled to heat independently and sequentially. Step S3022: Alternatively, during the second cycle, the second heating element 52 and the first heating element 51 are controlled to heat independently and sequentially. It is understood that in each cycle, either the first heating element 51 or the second heating element 52 can be selected to heat, allowing the atomizing device 100 to produce different flavors in different cycles within a single inhalation cycle, providing the user with a richer experience.
[0161] In some embodiments, the power of the first heating element 51 in the first cycle is different from its power in the second cycle. The power of the second heating element 52 in the first cycle is different from its power in the second cycle. Alternatively, the power of the first heating element 51 in the first cycle is the same as its power in the second cycle. The power of the second heating element 52 in the first cycle is the same as its power in the second cycle. It is understood that the atomizing device can control the heating power of the first heating element 51 and the second heating element 52 in each cycle, and can also make the atomizing device 100 produce different flavors in different cycles within a single vaping cycle, providing the user with a richer experience.
[0162] Understandably, the order of steps S301, S302, S303, and S304 can be changed or repeated, and can be adjusted according to user needs.
[0163] In some embodiments, the first heating element 51 and the second heating element 52 may be subjected to steps S301, S302, S303 and S304 in the structure shown in FIG9 and FIG10.
[0164] Please refer to Figure 14, which is a schematic flowchart of the atomization control method in some embodiments of this application. One atomization control method further includes: step S401: controlling the first heating element 51 and the second heating element 52 in series for heating during at least one second suction cycle.
[0165] Step S402: Control the first heating element 51 and the second heating element 52 to be connected in parallel during at least one second suction cycle for heating.
[0166] Step S403: Control the first heating element 51 and the second heating element 52 to heat up separately and sequentially during at least one second suction cycle.
[0167] Understandably, the heating method is different for each vaping cycle, resulting in different tastes for each vaping cycle, thus giving the atomizing device 100 a richer taste.
[0168] Step S402 may include steps S4021 and S4022. Step S4021: Controlling the first heating element 51 and the second heating element 52 in parallel for heating for a first duration during at least one second suction cycle. Step S4022: Controlling the first heating element 51 and the second heating element 52 in parallel for heating for a second duration during at least one second suction cycle.
[0169] In some embodiments, the total power of the first heating element 51 and the second heating element 52 during a first duration is greater than the total power during a second duration. It is understood that the heating duration and heating power of the first heating element 51 and the second heating element 52 in each suction cycle can be varied to result in different tastes in each suction cycle.
[0170] In some embodiments, the first duration or the second duration may be less than or equal to the second suction cycle in order to control the heating power of the heating element.
[0171] In some embodiments, the first duration includes a first sub-duration and a second sub-duration. The first sub-duration or the second sub-duration may be less than or equal to the first duration, and the first sub-duration and the second sub-duration may be equal or unequal.
[0172] Before step S4022, step S501 can be performed: controlling the first heating element 51 and the second heating element 52 to be connected in parallel during at least one second suction cycle to perform a first sub-duration of heating.
[0173] After step S4022 is performed, step S502 can be performed: controlling the first heating element 51 and the second heating element 52 to be connected in parallel during at least one second suction cycle to perform a second sub-duration of heating.
[0174] Understandably, the first heating element 51 and the second heating element 52 can be controlled to use different heating methods within each sub-time period, making the heating method of the atomizing device 100 more diverse and enabling the atomizing device 100 to have a richer flavor.
[0175] In some embodiments, the first sub-duration and the second sub-duration may be equal or unequal. In some embodiments, the first duration may also include a third sub-duration or even more sub-durations, which will not be elaborated here. In some embodiments, the first sub-duration can be further divided to make the heating method of the atomizing device 100 more diverse and provide a richer flavor.
[0176] Understandably, the order of steps S401, S402, S303 and S501, S502 can be changed or repeated, and can be adjusted according to user needs.
[0177] In some embodiments, the first heating element 51 and the second heating element 52 may be subjected to steps S401, S402, S303 and S501, S502 in the structure shown in FIG9 and FIG10.
[0178] This application provides a specific implementation example, as shown in Table 2.
[0179] Table 2: Control Logic Table for Heating Components of Atomizing Device
[0180] As shown in Table 2, in the implementation examples, the first heating element 51 and the second heating element 52 are disposed within the aerosol flow channel 1003 and arranged in a direction perpendicular to the extension direction of the aerosol flow channel 1003. The first heating element 51 and the second heating element 52 are at the same distance from the mouthpiece 1001. The first heating element 51 and the second heating element 52 can heat atomizing substrates with different flavors respectively. After the two atomizing substrates are heated separately, they can be mixed in the aerosol flow channel 1003 and inhaled together by the user.
[0181] For the first induction (0-0.2s), the first heating element 51 and the second heating element 52 are heated to no more than 200℃ for preheating. For the first induction (0.2-0.4s), the first heating element 51 is heated individually with 8W power. For the first induction (0.4-0.6s), the second heating element 52 is heated individually with 10W power. For the first induction (0.6-0.8s), the first heating element 51 and the second heating element 52 are heated together with 8W power. For the first induction (0.8-1s), the first heating element 51 and the second heating element 52 are heated together with 8W power. For the first induction (1-1.2s), the second heating element 52 is heated individually with 10W power. For the first induction (1.2-1.4s), the first heating element 51 is heated individually with 10W power. For the first induction (1.4-1.6s), the second heating element 52 is heated individually with 8W power. Understandably, in the implementation example shown in Table 1, one suction cycle is 1.6s. Within one suction cycle, the first heating element 51 and the second heating element 52 can be controlled to heat separately, or the first heating element 51 and the second heating element 52 can be controlled to heat together, and the heating power of each heating element can also be controlled.
[0182] In some embodiments, the direction of the current in the heating element may change once every 0.1s or once every 0.2s, and no specific limitation is made here.
[0183] During the second heating cycle (0-0.2s), the first heating element 51 and the second heating element 52 are heated to no more than 200℃ for preheating. During the second heating cycle (0.2-0.4s), the first heating element 51 is heated individually with a power of 10W. During the second heating cycle (0.4-0.6s), the second heating element 52 is heated individually with a power of 8W. During the second heating cycle (0.6-0.8s), the first heating element 51 and the second heating element 52 are heated together with a power of 10W and a power of 8W. During the second heating cycle (0.8-1s), the first heating element 51 and the second heating element 52 are heated together with a power of 10W and a power of 8W. During the second heating cycle (1-1.2s), the second heating element 52 is heated individually with a power of 8W. During the second heating cycle (1.2-1.4s), the first heating element 51 is heated individually with a power of 10W. During the second heating cycle (1.4-1.6s), the second heating element 52 is heated individually with a power of 8W.
[0184] Understandably, by controlling the different heating power of the first heating element 51 and the second heating element 52 at each time period within a suction cycle, the taste profile of the mixed aerosol can be altered, providing users with a better experience.
[0185] As shown in Table 2, the third to sixth inlets all use different control logics to control the heating power of the first heating element 51 and the second heating element 52 at different times, thereby changing the flavor profile of the atomizer. These details will not be elaborated upon here. Of course, the control logic of this application is not limited to the implementation examples shown in Table 2.
[0186] The atomizing device 100 of this application may further include a computer-readable storage medium storing a computer program. The aforementioned atomization control method can be stored as a computer program in the computer-readable storage medium, and the processor can execute the program in the computer-readable storage medium to achieve the purpose of executing the atomization control method, thereby controlling the operating state of the two heating elements in the heating control circuit 101.
[0187] In some embodiments, the atomization control method is pre-written into the processor's internal computer-readable storage medium in the form of an executable computer program. After the atomization device 100 is powered on, the processor automatically reads and loads the computer program from the computer-readable storage medium to initialize peripherals such as the ADC (analog-to-digital converter) module and the PWM (pulse width modulation) module. The computer program then enters the main control loop, continuously acquiring signals from the detection circuit and calculating and controlling the power output to the heating element in real time accordingly.
[0188] Specifically, the processor reads analog signals from the resistance detection circuit 1021 and the voltage detection circuit 1022 through its built-in ADC (analog-to-digital converter) module and converts them into digital values. These digital values serve as input parameters for the control algorithm, which, after processing, generates corresponding PWM (pulse width modulation) control signals. These PWM control signals control the on / off states of six switching devices through the control circuit 30, thereby achieving precise and automatic control of the operation of the first heating element 41 and the second heating element 42. This process can be repeated continuously during the continuous operation of the atomizing device 100. To ensure the control target is achieved, operation is immediately stopped if the preset time or temperature is exceeded, ensuring the stable and reliable operation of the atomizing device 100.
