[0029] The atomizing device provided in the embodiments of this application will now be described in detail.

[0030] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an atomizing device provided in an embodiment of this application. Please refer to it. Figure 1The atomizing device includes: a heating unit 1 for generating heat to atomize the atomizing matrix within the atomizing device; a power supply unit 2 for supplying power to the heating unit 1; a switching unit 3 for changing the output power from the power supply unit 2 to the heating unit 1 according to the duty cycle, so that the heating unit 1 generates heat; a sensor 4 for outputting a trigger signal in response to a predetermined trigger action; and a controller 5 for determining the duty cycle of the switching unit 3 in response to the trigger signal. The controller 5 can determine the duty cycle of the switching unit 3 as a first duty cycle, which is greater than a target duty cycle (the duty cycle when the atomizing device is operating stably), during a first time period; during a subsequent second time period, determine the duty cycle of the switching unit 3 as a second duty cycle, which is less than the target duty cycle; and during a subsequent third time period, determine the duty cycle of the switching unit 3 as the target duty cycle.

[0031] In some embodiments, since the heating unit 1 is an electronic component, the power supply unit 2 needs to supply power to the heating unit 1 so that the heating unit 1 heats up, thereby atomizing the atomizing matrix in the atomizing device, and thus enabling the atomizing device to perform atomizing work.

[0032] To ensure that the temperature of the heating unit 1 remains within a stable range when it is heating, and that the atomization operation of the atomizing device is not affected by excessively high or low temperatures, the atomizing device also needs to include a switching unit 3. The switching unit 3 can change the output power from the power supply unit 2 to the heating unit 1 according to the duty cycle. Therefore, the heating rate and temperature of the switching unit 3 are related to the output power of the power supply unit 2.

[0033] It should be noted that the switching unit includes at least one switching transistor, and the control terminal of the at least one switching transistor is connected to the output port of the controller's PWM (Pulse Width Modulation) signal. The switching transistor can be an N-MOS (N-Metal-Oxide-Semiconductor) transistor or a P-MOS (P-Metal-Oxide-Semiconductor) transistor; or, in application, the type or structure of the switching unit can be selected according to the actual situation. This application embodiment does not limit this.

[0034] In some embodiments, the sensor 4 can detect whether the atomizing device is in use. When the atomizing device is in use, the sensor 4 can output a trigger signal, that is, the sensor 4 can output a trigger signal in response to a predetermined triggering action.

[0035] After the sensor 4 outputs a trigger signal, in order to improve the heating efficiency of the atomizing device, the controller 5 can respond to the trigger signal and determine the corresponding duty cycle, so that the switching unit 3 controls the output power of the power supply unit 2 to the heating unit 1 according to the duty cycle, thereby controlling the heating rate and temperature of the heating unit 1.

[0036] Since the heating rate and temperature required by the heating unit 1 may vary at different times, the controller 5 can determine the corresponding duty cycle at different times.

[0037] In some embodiments, during a first time period, the controller 5 can determine the duty cycle of the switching unit 3 as a first duty cycle. The first time period can be the initial period before the atomizing device is used this time, that is, the duration of the initial trigger signal received this time. For example, assuming that the total duration of the atomizing device being used this time is 8 seconds, the first time period can be the period from 0 to 1 second.

[0038] It should be noted that the controller 5 can time the duration of the trigger signal to determine the corresponding time period within the duration of the trigger signal, thereby ensuring that each time period has a corresponding duty cycle; alternatively, the atomizing device may also include a timing unit to time the duration of the trigger signal. This application embodiment does not limit this aspect.

[0039] Since the heating unit 1 needs to heat up rapidly during the first time period, the first duty cycle needs to be greater than the target duty cycle. The target duty cycle is the duty cycle when the atomizing device is working stably. In other words, the target duty cycle is the duty cycle when the temperature of the heating unit 1 is stable. That is, the heating unit 1 does not need to perform rapid temperature adjustment, but only needs to perform the duty cycle when the temperature is maintained.

[0040] In some embodiments, the first duty cycle is 1. That is, during the first time period, the power supply unit 2 outputs full power to the heating unit 1, thereby enabling the heating unit 1 to heat up rapidly during the first time period.

[0041] As an example, please refer to Figure 2 , Figure 2 This is a schematic diagram comparing temperature curves within a first time period provided in an embodiment of this application. The solid line represents the temperature curve when the first duty cycle is 1, and the dashed line represents the temperature curve when the first duty cycle is not 1. Figure 2 As can be seen from the diagram, the heating rate corresponding to the solid line is greater than the heating rate corresponding to the dashed line. Therefore, it can be concluded that when the first duty cycle is 1, the heating unit 1 can be heated up rapidly in the first time.

[0042] In the subsequent second time period, that is, the time period after the first time period, the controller 5 needs to determine the corresponding duty cycle for the second time period. For example, assuming that the total duration of the atomizing device being used this time is 8 seconds, and the first time period is the period from 0 to 1 second, then the second time period can be the period from 1 to 3 seconds. Of course, in some other embodiments, the first time period and the second time period do not need to be strictly continuous. For example, the second time period can also be the period from 1.5 to 3 seconds. The period from 1 to 1.5 seconds can be used as the heating tail section, that is, heating is carried out based on the residual temperature of the heating unit.

[0043] Because the heating unit 1 heats up rapidly during the first time period, it may become too hot, causing a burnt taste in the atomizing device. Therefore, during the second time period, the duty cycle of the switching unit 3 needs to be reduced to decrease the power output from the power supply unit 2 to the heating unit 1, thereby reducing the heating rate of the heating unit 1. Thus, the controller 5 can set the duty cycle of the switching unit 3 to a second duty cycle, which is less than the target duty cycle, thereby reducing the heating rate of the heating unit 1 during the second time period and preventing a burnt taste.

[0044] In some embodiments, the second duty cycle is 0. That is, during the second time period, the power supply unit 2 does not output power to the heating unit 1, thereby preventing the atomizing device from developing a burnt taste due to excessively high temperature of the heating unit.

[0045] As an example, please refer to Figure 3 , Figure 3 This is a schematic diagram comparing the temperature curves of the first time period and the second time period provided in an embodiment of this application. The solid line represents the temperature curve corresponding to a first duty cycle of 1 and a second duty cycle of 0, while the dashed line represents the temperature curve corresponding to a first duty cycle that is not 1 and a second duty cycle that is not 0. Figure 3 As can be seen, the temperature of the solid line is more stable than that of the dashed line during the second time period. Therefore, it can be concluded that when the second duty cycle is 0, the temperature of heating unit 1 can be more stable.

[0046] In the subsequent third time period, that is, the time period after the second time period, the controller 5 needs to determine the corresponding duty cycle for the third time period. For example, assuming that the total duration of the atomizing device being used this time is 8 seconds, the first time period is the period from 0 to 1 second, the second time period is the period from 1 to 3 seconds, then the third time period can be the period from 3 to 8 seconds.

[0047] Continuing the description above, because the switching unit 3 controls the power output from the power supply unit 2 to the heating unit 1 according to the corresponding duty cycle, the heating unit 1 heats up rapidly in the first time period and slows down the heating rate in the second time period. This ensures that the heating unit 1 can heat up quickly while maintaining the flavor of the atomizing device. Therefore, in the fourth time period, there is no need for rapid temperature adjustment; it is only necessary to maintain the temperature to ensure stable operation of the atomizing device. Thus, in the fourth time period, the controller 5 can determine the duty cycle of the switching unit 3 as the target duty cycle to ensure stable operation of the atomizing device.

[0048] In some embodiments, the first time period includes a first cycle, and the second time period includes a second cycle and a third cycle. That is, when the first duty cycle is 1 and the second duty cycle is 0, the heating unit 1 requires two cycles, namely the first cycle and the second cycle, to alleviate and prevent a burnt smell. When the first duty cycle is not 1 and / or the second duty cycle is not 0, the number of cycles included in the second time period may vary. For example, if the first duty cycle is less than 1, then the second time period may only require 1.5 cycles to avoid a burnt smell.

[0049] The length of the cycle is related to the frequency of the control switch unit 3. For example, if the control frequency is 50 Hz, then the length of one cycle is 20 milliseconds. In order to prevent the temperature of the heating unit 1 from becoming too high after the first cycle, the heating rate needs to be controlled in the second and third cycles to avoid a burnt smell.

[0050] In some embodiments, please refer to Figure 4 .from Figure 4 As can be seen from the diagram, the atomizing device may also include: a voltage detection unit 6, used to measure the voltage corresponding to the multiple cycles included in the third time period of the power supply unit 2, so as to obtain the target reference voltage corresponding to the multiple cycles, the target reference voltage being the voltage output by the power supply unit 2 in the previous cycle; the controller 5 may also determine the target output voltage corresponding to the current cycle, the target output voltage being the voltage corresponding to the target output power of the current cycle, and then determine the corresponding target duty cycle based on the target output voltage and the target reference voltage corresponding to the current cycle.

[0051] During the third time period, the change in the power of the power supply unit 2 will cause the output voltage of the power supply unit 2 to fluctuate. If the switching unit 3 controls the power output of the power supply unit 2 to the heating unit 1 according to the same target duty cycle during the third time period, the power output to the heating unit 1 may decrease as the power of the power supply unit 2 decreases, thereby causing the flavor of the atomizing device to deteriorate and reducing the user experience.

[0052] In some embodiments, an initial value can be set for the target duty cycle so that the controller 5 can determine a first duty cycle corresponding to a first time period and a second duty cycle corresponding to a second time period based on the initial value. The controller 5 can also update the value of the target duty cycle based on the target output voltage and the target reference voltage during a third time period.

[0053] In other words, different output powers are required in multiple cycles of the third time period to maintain the temperature of the heating unit 1. The voltage detection unit 6 needs to measure the voltage output by the power supply unit 2 respectively to obtain the target reference voltage corresponding to the current cycle.

[0054] As an example, assuming the third time period begins from the fourth cycle, the voltage detection unit 6 can measure the voltage output by the power supply unit 2 during the fourth cycle, so that the measured value can be used as the target reference voltage for the fifth cycle in subsequent processes. Similarly, the voltage detection unit 6 can also measure the voltage output by the power supply unit 2 during the fifth cycle, so that the measured value can be used as the target reference voltage for the sixth cycle in subsequent processes.

[0055] In addition, in some embodiments, the duty cycle corresponding to the first period in the third time period can be the initial value of the target duty cycle.

[0056] The controller 5 can also determine the voltage corresponding to the target output power in the current cycle and set this voltage as the target output voltage. As an example, the controller 5 can obtain the target output power for the current cycle based on the operating requirements of the atomizing device, which is sufficient to maintain the flavor of the atomizing device, and then obtain the corresponding target output voltage based on the target output power.

[0057] Continuing from the above description, after the controller 5 obtains the target output voltage and target reference voltage corresponding to the current cycle, it can also determine the target duty cycle corresponding to the current cycle based on the target output voltage and target reference voltage corresponding to the current cycle, so as to update the target duty cycle. This allows the switching unit 3 to control the power output from the power supply unit 2 to the heating unit 1 according to the current target duty cycle, so as to maintain the flavor of the atomizing device.

[0058] It should be noted that the controller 5 can determine the target duty cycle as the ratio of the target output voltage to the target reference voltage, or it can determine the corresponding target duty cycle through other methods to update the initial value of the target duty cycle. This application embodiment does not limit this approach.

[0059] In some embodiments, when the output power of the power supply unit 2 is higher than a preset threshold, the resistance of the heating unit 1 is configured to a first resistance value, and when the output power of the power supply unit 2 is lower than the preset threshold, the resistance of the heating unit 1 is configured to a second resistance value, wherein the first resistance value is lower than the second resistance value. The resistance value of the heating unit 1 ensures that when the power supply unit 2's charge is lower than the charge threshold, the output power of the power supply unit 2 meets the discharge requirements of the atomizing device.

[0060] Because power supply unit 2 has a stronger driving capability when fully charged (equivalent to higher output voltage and higher power), and a weaker driving capability when its charge is lower (equivalent to lower output voltage and lower power). For example, assuming power supply unit 2 is 4.2V when fully charged and can support an output of 20W to 25W, but when its output voltage drops to 3V, it may not be able to support 25W, and may even drop to 18W. Therefore, before the atomizing device leaves the factory, technicians need to select a heating unit 1 with a lower resistance to ensure that power supply unit 2 can still output the corresponding power to meet the discharge requirements of the atomizing device even when its charge is below the threshold.

[0061] Furthermore, since there are requirements for the load power, for example, before the atomizing device leaves the factory, technicians will set its corresponding maximum and minimum power. The technicians will determine the resistance value of the heating unit 1 based on the maximum and minimum power, and then calculate the output voltage required by the power supply unit 2. If the current output voltage of the power supply unit 2 is higher than the required output voltage, a duty cycle is needed for adjustment, that is, the switching unit 3 controls the voltage output from the power supply unit 2 to the heating unit 1 according to the corresponding duty cycle.

[0062] Therefore, under low power requirements, the output voltage of the power supply unit 2 can be controlled by adjusting the duty cycle of the switching unit 3 to reduce its output power; however, under some high power requirements, such as exceeding the specified maximum power, the power supply unit 2 needs to be able to output a higher voltage. In this case, technicians need to select a heating unit 1 with a lower resistance value before leaving the factory.

[0063] In some embodiments, please refer to Figure 5 The power supply unit 2 also includes a battery cell 21. The discharge rate of the battery cell 21 can ensure that when the power supply unit 2's charge is lower than the charge threshold, the output power of the power supply unit 2 meets the discharge requirements of the atomizing device.

[0064] As described above, in order to meet the discharge requirements of the atomizing device under different conditions, technicians need to select a heating unit 1 with a lower resistance. Since the resistance of the heating unit 1 is reduced, the current is greater, and therefore the output power needs to be greater. Therefore, before the atomizing device leaves the factory, technicians need to select a battery cell 21 with a larger discharge rate to ensure that when the power supply unit 2's power is lower than the power threshold, its output power still meets the discharge requirements of the atomizing device.

[0065] As an example, please refer to Figure 6 , Figure 6 This is a power output comparison diagram provided in an embodiment of this application. The solid line represents the power output corresponding to the heating unit 1 with lower resistance and the battery cell 21 with a higher discharge rate, while the dashed line represents the power output corresponding to the heating unit with normal resistance and the battery cell with a normal discharge rate. Figure 6 As can be seen from the data, the output power corresponding to the solid line is more stable under different battery charge levels. This indicates that selecting the heating unit 1 with lower resistance and the battery cell 21 with a higher discharge rate ensures a relatively stable output power at different battery charge levels, meeting the discharge requirements of the atomizing device.

[0066] This embodiment of the application, by determining the duty cycle of the switching unit as a first duty cycle in the first time period, and ensuring that the first duty cycle is greater than the target duty cycle for stable operation of the atomizing device, enables the temperature of the heating unit to rise rapidly. In the second time period, by determining the duty cycle of the switching unit as a second duty cycle, and ensuring that the second duty cycle is less than the target duty cycle, it avoids the atomizing device from developing a burnt taste due to excessive temperature. In the third time period, by determining the duty cycle of the switching unit as the target duty cycle, it maintains the temperature stability of the heating unit, thereby preserving the flavor of the atomizing device and mitigating flavor decay. Furthermore, in the third time period, the target duty cycle value can be updated based on the target output voltage and target reference voltage corresponding to the current cycle, enabling more precise temperature control of the heating unit. Moreover, by selecting appropriate heating units and battery cells, even when the power supply unit's charge is below the power threshold, the output power of the power supply unit can still meet the discharge requirements of the atomizing device.

[0067] The heating control method for the atomizing device provided in the embodiments of this application will be explained in detail below.

The atomizing device includes a switching unit, and this method is applied to a controller within the atomizing device. Please refer to... Figure 7 The method includes the following steps:

[0069] Step 701: During the first time period, the duty cycle of the switching unit is determined as the first duty cycle, which is greater than the target duty cycle. The target duty cycle is the duty cycle when the atomizing device is working stably.

[0070] Step 702: In the subsequent second time period, the duty cycle of the switching unit is determined as the second duty cycle, which is less than the target duty cycle.

[0071] In some embodiments, the first duty cycle is 1 and the second duty cycle is 0; and / or, the first time period includes a first cycle and the second time period includes a second cycle and a third cycle.
