The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0062] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments.

Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.
[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0066] Currently, due to the limited number of ports available in processors or controllers such as microcontroller units (MCUs) in electronic atomization devices—far fewer than the number of LEDs in an LED module—directly driving the LEDs in the LED module through the processor or controller ports is insufficient to meet the module's requirements. Related technologies typically employ separate LED control chips or circuits to drive and control the brightness of LED modules or display arrays in LED displays, thereby increasing circuit size and cost.
[0067] This application provides a control method for an electronic atomizing device and a light-emitting diode module, which can control an LED module with a larger number of LEDs without adding additional control circuitry.
[0068] Figure 1 This is an optional structural diagram of the electronic atomizing device provided in the embodiments of this application. For example... Figure 1 As shown, the electronic atomizing device 1 includes a power supply 10, a processor 12, an LED module 13, and a memory 14; wherein the processor 12 includes N ports. N is an integer greater than 1. In some embodiments, the number N of ports in the processor 12 used to control the LED module 13 can be determined based on the actual available ports of the processor and the number of LEDs in the LED module.
[0069] For example, such as Figure 2 As shown, the processor 12 may include the MCU in the electronic atomization device, and the N ports may include the 8 input / output (I / O) ports on the MCU. In practice, depending on the processor, it may include other numbers of ports; this embodiment does not limit this.
[0070] based on Figure 1 The LED module 13 includes N groups of LEDs, and each group of LEDs includes N-1 LEDs. That is, the LED module 13 includes N*(N-1) LEDs or an N*(N-1) LED array. For the i-th group of N groups, the first ends of the N-1 LEDs in the i-th group are all connected to the i-th port of the processor 12, and the second ends are connected to the other N-1 ports (excluding the i-th port). In other words, the first end of each LED in the i-th group is connected to the i-th port of the processor 12, and the second end is connected to one of the other N-1 ports (excluding the i-th port). It should be noted that the second end of each LED is connected to a different port among the other N-1 ports.
[0071] Where i is greater than or equal to 1 and less than or equal to N. Each group of LEDs in the N groups is connected to the N ports in the manner described above for the i-th group of LEDs.
[0072] For example, taking the first end as the cathode of the LED and the second end as the anode of the LED as an example, based on Figure 2 An 8-port MCU, such as Figures 3-1 to 3-8 As shown, the first group of LEDs (DIG1) includes 7 LEDs: A1 to G1. The cathodes of A1 to G1 are all connected to port 1 of the MCU, and the anodes of A1 to G1 are connected to ports 2-8 of the MCU, i.e., connected to the other N-1 ports out of the 8 ports. The second group of LEDs (DIG2) includes 7 LEDs: A2 to G2. The cathodes of A2 to G2 are all connected to port 2 of the MCU, and the anodes of A2 to G2 are connected to ports (1, 3, 4, 5, 6, 7, 8) of the MCU. The third group of LEDs (DIG3) includes 7 LEDs: A3 to G3. The cathodes of A3 to G3 are all connected to port 3 of the MCU, and the anodes of A3 to G3 are connected to ports (1, 2, 4, 5, 6, 7, 8) of the MCU. The connection method for the fourth group of LEDs (DIG4) to the eighth group of LEDs (DIG8) follows the same pattern. Therefore, it is possible to Figures 3-1 to 3-8 Through the MCU's 8 ports, an LED module containing up to 56 (8*7) LEDs can be controlled, greatly increasing the number of LEDs that can be controlled by the MCU ports, and enabling the control of a large number of LEDs without additional control circuitry.
[0073] Similarly, the connection method where the first end is the anode of the LED and the second end is the cathode of the LED is as follows: Figures 3-9 to 3-16 As shown.
[0074] In this embodiment, based on the circuit connection described above, the power supply 11 is used to supply power to the LED module 13 via the processor 12. The power supply 11 can also supply power to other electrical components in the electronic atomization device, such as the heating element. The power supply 11 includes, but is not limited to, devices capable of providing electrical energy, such as batteries. Batteries may include disposable batteries or rechargeable batteries. The memory 14 is used to store executable instructions. It should be noted that in some embodiments, the memory 14 can be powered by the power supply 11, or by other power sources; this embodiment does not impose such limitations.
[0075] In some embodiments, the processor 12 is configured to implement the following control method for the LED module 13 in the electronic atomizing device 1 by executing executable instructions stored in the memory:
[0076] Determine the target scanning frequency; based on the target scanning frequency, output pulse width modulation (PWM) current to each of the N ports to light up the LED module 13.
[0077] In some embodiments, the processor 12, according to the target scanning frequency, outputs PWM current to each of the N ports to light up an LED connected to the port via the second terminal, thereby lighting up N*(N-1) LEDs in the LED module 13 in one scanning cycle corresponding to the target scanning frequency through (N-1) traversals.
[0078] In this embodiment, the processor 12 illuminates an LED connected to a port 13 by outputting a PWM current at one of the N ports in a scanning manner. This allows for (N-1) iterations of PWM current output at each of the N ports, illuminating each LED in the LED module 13 one by one, thus illuminating N*(N-1) LEDs within one scan cycle corresponding to the target scan frequency. The target scan frequency and scan cycle are reciprocals of each other, with the scan cycle representing the total duration for each LED in the LED module to illuminate once. Since the processor 12 illuminates the LEDs one by one, a higher target scan frequency makes the brightness changes of the LEDs less perceptible to the human eye, thereby reducing LED display flicker and improving display quality. In some embodiments, a minimum target scan frequency can be preset based on the perceptibility of LED brightness changes. For example, a 50Hz LED brightness change frequency is imperceptible to the human eye. Therefore, the minimum target scan frequency can be 50Hz.
[0079] In this embodiment, the processor 12 outputs PWM current at one port out of N ports at a time, and traverses all N ports to output PWM current within one scan cycle. This embodiment does not limit the order in which the N ports are traversed.
[0080] In some embodiments, the processor 12 is further configured to adjust the brightness of the LED by adjusting the duty cycle of the pulse width modulation current. When the processor 12 lights up the LED by outputting a pulse width modulation current, adjusting the duty cycle of the PWM current can control the magnitude of the average current flowing through the LED, thereby controlling the brightness of the LED.
[0081] In some embodiments, the duty cycle of the output PWM current can be controlled using software or hardware PWM. The more adjustable levels of the output duty cycle, the more adjustable levels of the LED brightness.
[0082] It is understood that the embodiments of this application realize the control of an LED module containing N*(N-1) LEDs using N ports of the processor, without the need for additional control circuitry, thereby reducing costs and enabling the control of an LED module with a larger number of LEDs.
[0083] In some embodiments, for the case where the first end is the cathode of the LED and the second end is the anode of the LED, the processor 12 is further configured to, when traversing to the j-th LED in the i-th group of LEDs, output a low level at the i-th port, output a pulse width modulation current at the port connected to the anode of the j-th LED, and output a high impedance state at the other N-2 ports, thereby lighting up the j-th LED, and then traversing and lighting up N*(N-1) LEDs within the scan cycle. Wherein, j is greater than or equal to 1 and less than or equal to N-1.
[0084] The N-2 ports that output high impedance include all ports except for the i-th port and the port connected to the anode of the j-th LED. Based on the target scanning frequency, each LED in each of the N groups of LEDs is lit in the same way as the j-th LED in the i-th group, thus allowing N*(N-1) LEDs to be lit throughout the scanning cycle.
[0085] For example, based on such Figures 3-1 to 3-8 The connection method between the LED and the processor port is shown, such as... Figure 4As shown, during period T1, the processor outputs a low level at port 1, outputs PWM current at port 2, and outputs a high impedance at the other N-2 ports (ports 3, 4, 5, 6, 7, and 8). This causes the PWM current to flow through the first LED (A1) of the first group of LEDs (DIG1) connected to port 2, thus lighting up the first LED (A1) in the first group of LEDs. During period T2, the processor outputs a low level at port 1, outputs PWM current at port 3, and outputs a high impedance at the other ports (ports 2, 4, 5, 6, 7, and 8). This causes the PWM current to flow through the second LED (B1) of the first group of LEDs connected to port 3, thus lighting up the second LED (B1) in the first group of LEDs. This process continues until, during period T56, the processor outputs a low level on port 8, a PWM current on port 7, and a high impedance on the other ports (ports 1, 2, 3, 4, 5, and 6). This causes the PWM current to flow through the 7th LED (DIG8) in the 8th group of LEDs connected to port 7 at its anode. Thus, during scan cycles T1 to T56, all 56 LEDs are illuminated. The next scan cycle follows the same procedure.
[0086] In some embodiments, for the case where the first end is the anode of the LED and the second end is the cathode of the LED, the processor 12 is further configured to output a pulse width modulation current at the i-th port when traversing to the j-th LED in the i-th group of LEDs, output a low level at the port connected to the second end of the j-th LED, and output a high impedance state at the other N-2 ports, thereby lighting up the j-th LED, and then traversing and lighting up the LED module during the scan cycle; j is greater than or equal to 1 and less than or equal to N-1.
[0087] For example, based on such Figures 3-9 to 3-16 The connection method between the LED and the processor port is shown. The processor is in Figure 4During time period T1, the processor outputs PWM current at port 1, outputs a low level at port 2, and outputs a high impedance at the other N-2 ports (ports 3, 4, 5, 6, 7, and 8). This causes the PWM current to flow through the first LED (A1') of the first group of LEDs (DIG1') connected to port 2, thus illuminating the first LED (A1') in the first group of LEDs. During time period T2, the processor outputs PWM current at port 1, outputs a low level at port 3, and outputs a high impedance at the other ports (ports 2, 4, 5, 6, 7, and 8). This causes the PWM current to flow through the second LED (B1') of the first group of LEDs connected to port 3, thus illuminating the second LED (B1') in the first group of LEDs. This process continues until, during period T56, the processor outputs PWM current at port 8, a low level at port 7, and a high impedance at the other ports (ports 1, 2, 3, 4, 5, and 6). This causes the PWM current to flow through the 7th LED (DIG8') in the 8th group of LEDs connected to port 7 via the cathode. Thus, during scan cycles T1 to T56, all 56 LEDs are illuminated. The next scan cycle follows the same procedure.
[0088] For example, depending on the target scanning frequency requirements, the duration of each time period from T1 to T56 can be 16 microseconds to ensure that the changes in LED brightness are not perceived by the human eye.
[0089] It should be noted that the traversal method or order in the above embodiments is only an example. The processor 12 may also traverse the N ports in other orders, and / or traverse each LED in each group of LEDs in other orders to output PWM current. The embodiments of this application do not limit the traversal order.
[0090] It should be noted that in the above example, the MCU can also control the brightness of the LED it illuminates by controlling the duty cycle of the PWM current.
[0091] In some embodiments, the electronic atomizing device further includes a heating element, and a power source is used to power the heating element. In some embodiments, based on Figure 1 ,like Figure 5As shown, the power supply 11 can supply power to the heating element 15 via the processor 12. The heating element 15 is used to heat the substrate to be atomized using the power supply. Exemplarily, the heating element may include an atomizer in an electronic atomization device, and the substrate to be atomized may include a liquid substrate or a solid substrate. Exemplarily, the liquid substrate may include drugs or other substances such as e-liquid, etc., and the specific selection depends on the actual situation; this application embodiment does not limit the specific choice.
[0092] In this embodiment, when the heating element 15 is working, the power supply 11 simultaneously supplies power to both the LED module 13 and the heating element 15. During this time, the power supply voltage drops, and after the heating element 15 stops heating, the voltage of the power supply 11 rises again. Because this embodiment uses a scanning method to light the LED, the change in power supply voltage during the operation of the heating element 15 may cause the LED brightness to flicker. Figure 6 As shown, if the heating frequency of the heat source is 100Hz and the processor's target scanning frequency for the LED module is 50Hz (corresponding to a scanning period of approximately 20ms), the human eye cannot perceive LED flickering at a 50Hz LED brightness-darkness change frequency when the heat source is not heating. However, when the heat source is heating, because the heating frequency is 100Hz (period of 10ms), the power supply voltage changes at a frequency of 100Hz, causing the LED brightness-darkness change period to become longer, thus resulting in visible LED flickering.
[0093] To prevent LED flickering that may be caused by heating of the heating element, the processor 12 may also be used to: acquire the heating frequency of the heating element 15; and determine the target scanning frequency based on the heating frequency.
[0094] For example, based on the applicant's extensive testing experience, when the heating frequency of the heating element is 100Hz, the target scanning frequency needs to reach at least 400Hz (2.5ms cycle) to ensure that the LED does not flicker. To be compatible with higher heating frequencies, the target scanning frequency can be set to 800Hz.
[0095] In some embodiments, to ensure that the LED module does not flicker at any heating frequency, the processor 12 is further configured to: determine a target scanning frequency that is M times the first frequency threshold, where M is greater than or equal to 3, when the heating frequency of the heating element 15 is less than or equal to a first frequency threshold; and determine a target scanning frequency that is greater than or equal to a second frequency threshold, where the second frequency threshold is K times the first frequency threshold, where K is greater than or equal to 4, when the heating frequency of the heating element 15 is greater than the first frequency threshold.
[0096] For example, when the heating frequency of the heating element 15 is less than 100Hz, the target scanning frequency should be at least greater than or equal to 3 times the heating frequency (and not less than 50Hz). If it is greater than or equal to 4 times the heating frequency, the anti-flicker effect is better, and the higher the target scanning frequency, the better the anti-flicker effect.
[0097] When the heating frequency of the heating element 15 is greater than or equal to 100Hz, the target scanning frequency should be greater than or equal to 400Hz. The higher the target scanning frequency, the better the anti-flicker effect.
[0098] In some embodiments, the processor 12 is further configured to determine whether the heating element 15 is in a working state. If the heating element 15 is in a working state, the processor acquires the heating frequency to determine the target scanning frequency based on the heating frequency. If the heating element 15 is not in a working state, a preset or default frequency value may be used, such as a frequency value determined based on the perceptibility of the human eye.
[0099] It should be noted that in some embodiments, the processor 12 can also be used to control the heating of the heating element 15 and / or other functions in the electronic atomization device 1. Exemplarily, the same processor in the electronic atomization device can be used to control the LED module, control the heating of the heating element, detect the power supply, etc., and this application embodiment is not limited to this.
[0100] Understandably, determining the target scanning frequency of the LED module based on the heating frequency of the heating element can avoid the impact of the heating element's operation on the LED display effect and improve the LED display effect.
[0101] This application also provides a control method for a light-emitting diode module, applied to the processor 12 in any of the electronic atomizing devices described above in this application. For example... Figure 7 As shown, the control method for the light-emitting diode module includes:
