[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0047] In order to better understand the present application, the problem to be solved by the present application is first described. Figure 1 , Figure 1 The end of the switch module 130 connected to the heating element 140 is defined as A. During the normal operation of the circuit, the clock module (the clock module can be a separate module or a clock module set in the processing module) is used to detect the voltage change at point A and record the time when the voltage changes. At the same time, when the processing module sends a control signal, it can obtain the time when the control signal is sent to the switch module. The detection result obtained is as follows: Figure 2 As shown, Figure 2 The dotted box shows the time when the voltage change occurs at point A, and the solid box shows the time when the voltage of the pulse control signal output by the processing module 110 changes. If the delay when the switch module 130 is turned on is measured, first set the GPIO port (or point A) to a rising edge trigger. When the pulse signal PWM is set to a high level (set from a low level state to a high level state), record the current system clock TICK number, recorded as t1. When the GPIO port interrupt is triggered, record the clock TICK number when the interrupt occurs, recorded as t2. Then t2-t1 can be considered as the delay caused by the MOSFET when the switch module 130 is turned on (of course there will be a GPIO interrupt delay, which can be ignored at this time). If the delay when the switch module 130 is turned off is measured, set the GPIO port (point A) to a falling edge trigger. When the pulse signal PWM is set to a low level (set from a high level state to a low level state, such as Figure 2 X1 in the middle), record the current system clock number, record it as t3, when the GPIO port interrupt is triggered, such as Figure 2 At point X2, the clock tick number when the interruption occurs is recorded as t4, and t4-t3 can be considered as the delay caused by the MOSFET when the switch module 130 is turned off (there will be a GPIO interruption delay, which is ignored at this time). Figure 2 As shown, in the process of setting the low level state to the high level state, the value of t4-t3 is 9.4us, that is, when the switch module 130 is closed, the switch module 130 is closed for a delay of 9.4us at position A. The value of t2-t1 is very small and can be basically ignored.
[0048] It should be noted that the delay test results may be different when different switch modules 130 are used, that is, the delay may also be caused during the opening process of the switch module 130, and the specific time of the delay caused by closing the switch module 130 may be different.
[0049] Due to the above phenomenon, during the control process, when the switch module 130 is turned off, energy still passes due to the delay phenomenon (when the switch module 130 is turned on, if there is a delay phenomenon, the energy will not pass in time), which will cause the actual output power to be different from the target output power. Therefore, in order to solve the above problem, this application is proposed.
[0050] In one embodiment, a control circuit for output power of an electronic atomization device is provided, such as Figure 1 As shown, the control circuit includes:
[0051] A power module 110, a processing module 120, a switch module 130 and a heating body 140. The control end of the switch module 130 is connected to the processing module 120, the first end is connected to the power module 110, and the second end is connected to the heating body 140; the power module 110 is also connected to the processing module 120, and the power module 110 is used to supply power to the processing module 110 so that the processing module 110 can work normally. The power module 110 is also used to provide energy to the heating body 140 so that the heating body 140 can work normally. The processing module 110 can send a pulse signal to the switch module 130 according to the target power, so as to control the on and off of the switch module 130, so as to adjust the energy provided by the power module 110 to the heating body 140, and adjust the output power of the power module 110. The processing module 120 may include one or more processing cores. The processing module 10 uses various interfaces and lines to connect the various parts of the entire electronic atomization device, and executes various functions and processes data of the electronic atomization device by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processing module 120 can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The power module 110 includes batteries or batteries for storing electrical energy. The heating element 140 can be a liquid guide and a heating film attached to the liquid guide. By outputting power to the heating film, the heating film can be heated to atomize the aerosol atomization matrix transmitted by the liquid guide.
[0052] The detection end (GPIO) of the processing module 120 is connected to one end of the heating element 140 connected to the second end of the switch module 130. The processing module 120 is integrated with a clock module, and the clock module can also exist separately in the specific implementation, that is, the control circuit includes: a power module 110, a processing module 120, a switch module 130, a clock module and a heating element 140. The clock module is used to obtain the first moment of sending a control signal to the control end of the switch module 130 and the second moment detected by the detection end corresponding to the change of the control signal; the processing module 120 is used to obtain the delay of the switch module 130 according to the first moment and the second moment, and adjust the duty cycle of the pulse signal according to the delay, and the pulse signal is used to control the power module 110 to provide energy to the heating element 140.
[0053] Specifically, the clock module obtains the moment of sending the control signal to the control end of the switch module. For the convenience of description, the obtained moment is defined as the first moment. The moment of sending the control signal to the control end of the switch module specifically includes: the moment of changing from a low level to a high level and / or the moment of changing from a high level to a low level. The clock module can also obtain the moment of the corresponding change detected by the detection end corresponding to the control signal. For the convenience of description, the moment of the corresponding change detected by the detection end corresponding to the control signal is defined as the second moment, specifically including: the moment of changing from a low level to a high level and / or the moment of changing from a high level to a low level. Correspondingly, in a specific implementation, the first moment is the moment when the switch module is turned on, and the second moment is the moment when the detection end detects that the switch module is completely turned on; or, the first moment is the moment when the switch module is turned off, and the second moment is the moment when the detection end detects that the switch module is completely turned off.
[0054] The processing module 120 is used to obtain the delay of the switch module 130 according to the first moment and the second moment, and adjust the duty cycle of the pulse signal according to the delay. Specifically, if the delay obtained is the delay when the switch module 130 is turned on, the duty cycle of the pulse signal is increased; if the delay obtained is the delay when the switch module 130 is turned off, the duty cycle of the pulse signal is reduced so that the power module 110 provides energy to the heating element 140 to reach the target value.
[0055] The control circuit of the output power of the above-mentioned electronic atomization device includes: a power module, a processing module, a switch module and a heating body; the control end of the switch module is connected to the processing module, and the processing module controls the switch module to be turned on, so that the power module provides energy to the heating body; the detection end of the processing module is connected to one end of the switch module connected to the heating body; the processing module is used to obtain the first moment of sending a control signal to the control end of the switch module and the second moment detected by the detection end corresponding to the change of the control signal; the processing module is used to obtain the delay of the switch module according to the first moment and the second moment, and adjust the duty cycle of the pulse signal according to the delay, and the pulse signal is used to control the power module to provide energy to the heating body. In the above manner, since the delay of the switch module will affect the output power of the power module, the present application obtains the delay of the switch module by obtaining the moment of sending the control signal and the moment of the corresponding detection end change, and then uses the delay to adjust the duty cycle of the output power, thereby improving the accuracy of the output power.
[0056] In one embodiment, Figure 4As shown, the circuit also includes: a voltage-dividing detection module 150, a first end of the voltage-dividing detection module 150 is connected to one end of the heating element 140 connected to the second end of the switch module 130, a second end is connected to the detection end GPIO of the processing module 120, and a third end is grounded. It should be noted that the resistance value of the voltage-dividing detection module 150 is very large, much larger than the resistance value of the heating element 140. This makes the detection result as accurate as possible (the larger the resistance value, the less energy consumed in the measurement).
[0057] Specifically as an embodiment, Figure 5 As shown, the voltage-dividing detection module 150 includes a first resistor 151 and a second resistor 152 connected in series, the detection end of the processing module 120 is connected between the first resistor 151 and the second resistor 152, and one end of the first resistor 151 and the second resistor 152 away from the other is connected between the second end of the switch module 130 and the heating element 140. In a specific implementation, the voltage-dividing detection module 150 may also include a plurality of resistors, and the function of providing the plurality of resistors in the voltage-dividing detection module 150 is to divide the voltage to prevent the voltage in the circuit from exceeding the voltage that the detection end of the processing module 120 can withstand.
[0058] In one embodiment, Figure 6 As shown, the circuit further includes a third resistor 160, and the third resistor 160 is connected between the control end of the switch module 130 and the processing module 120. The third resistor can reduce the current of the circuit and protect the device.
[0059] In one embodiment, Figure 7 As shown, the circuit further includes a fourth resistor 170, one end of which is connected between the control end of the switch module 130 and the third resistor 160; and the other end is connected between the power module 110 and the first end of the switch module 130. As an example, the switch module 130 may be a transistor, and the fourth resistor 170 may protect the control end and the first end of the transistor.
[0060] In one embodiment, Figure 8 As shown, the switch module 130 includes a first transistor 131 and a second transistor 132. The control end of the first transistor 131 is connected to the processing module 120, the first end is grounded, and the second end is connected to the control end of the second transistor 132. The first end of the second transistor 132 is connected to the power module 110, and the second end is connected to the heating element 140. In this embodiment, the switch module 130 is composed of two transistors, and the delay will be higher than that of one transistor.
[0061] In one embodiment, Fig. 9As shown, the circuit further includes a fifth resistor 180, one end of which is connected between the processing module 120 and the control end of the first transistor 131, and the other end is grounded. The fifth resistor 180 can share the voltage on the transistor to protect the circuit.
[0062] In one embodiment, Fig.10 As shown, the circuit further includes a sixth resistor 190, one end of which is connected between the second end of the first transistor 131 and the control end of the second transistor 132; and the other end is connected between the power module 110 and the first end of the second transistor 132. The sixth resistor 190 protects the control end and the first end of the second transistor 132.
[0063] Based on the same inventive concept, the embodiment of the present application also provides a method for controlling the output power of an electronic atomization device for realizing the control circuit of the output power of the electronic atomization device involved above. The implementation scheme for solving the problem provided by this method is similar to the implementation scheme recorded in the above-mentioned electronic atomization device, so the specific limitations in the embodiments of the control method for the output power of one or more electronic atomization devices provided below can refer to the limitations on the control of the output power of the electronic atomization device above, and will not be repeated here.
[0064] In one embodiment, Fig.11 As shown, the present application provides a method for controlling the output power of an electronic atomization device, the control method is applied to a control circuit of the electronic atomization device, the control circuit includes a power module, a processing module, a switch module and a heating body; the control end of the switch module is connected to the processing module, and the processing module controls the switch module to be turned on, so that the power module provides energy to the heating body; the detection end of the processing module is connected to one end of the switch module connected to the heating body; based on the above embodiment, the method includes:
[0065] Step 1110, obtaining the delay of the switch module;
[0066] Step 1120, adjusting the duty cycle of the pulse signal according to the delay, wherein the pulse signal is used to control the power module to provide energy to the heating element.
[0067] As an embodiment, each step of this embodiment can be applied to the control circuit of the output power of the electronic atomization device described in any of the above embodiments. The delay of the switch module is obtained through the clock module in the circuit. The delay of the switch module can also be measured in advance when leaving the factory, and the delay is stored in the electronic atomization device. During the normal operation of the electronic atomization device, the processing module reads the pre-stored delay and adjusts the duty cycle of the pulse signal according to the delay, thereby improving the accuracy of the output power. That is, when the pulse signal changes from a low level to a high level, the duty cycle of the pulse signal is increased; when the pulse signal changes from a high level to a low level, the duty cycle of the pulse signal is reduced, so that the power module 110 provides energy to the heating element 140 to reach the target value. Specifically, the detection end (GPIO) of the processing module is connected to one end of the switch module connected to the heating element. The processing module is integrated with a clock module, and the clock module can also exist separately in the specific implementation. The clock module is used to obtain the first moment of sending a control signal to the control end of the switch module and the second moment detected by the detection end corresponding to the change of the control signal; the processing module is used to obtain the delay of the switch module according to the first moment and the second moment, and adjust the duty cycle of the pulse signal according to the delay, and the pulse signal is used to control the power supply module to provide energy to the heating element.
[0068] Specifically, the clock module obtains the moment of sending the control signal to the control end of the switch module. For the convenience of description, the obtained moment is defined as the first moment. The moment of sending the control signal to the control end of the switch module specifically includes: the moment of changing from a low level to a high level and / or the moment of changing from a high level to a low level. The clock module can also obtain the moment of corresponding change detected by the detection end corresponding to the control signal. For the convenience of description, the moment of corresponding change detected by the detection end corresponding to the control signal is defined as the second moment, specifically including: the moment of changing from a low level to a high level and / or the moment of changing from a high level to a low level. Correspondingly, in a specific implementation, the first moment is the moment when the switch module is turned on, and the second moment is the moment when the detection end detects that the switch module is turned on; or, the first moment is the moment when the switch module is turned off, and the second moment is the moment when the detection end detects that the switch module is turned off. The processing module obtains the delay of the switch module according to the first moment and the second moment, and adjusts the duty cycle of the pulse signal according to the delay. Specifically, if the delay obtained is the delay when the switch module is turned on, the duty cycle of the pulse signal is increased; if the delay obtained is the delay when the switch module is turned off, the duty cycle of the pulse signal is reduced so that the power module provides energy to the heating element to reach the target value.
[0069] The execution process of each step in this implementation can refer to the above embodiment and will not be repeated here.
[0070] In the control method of the above-mentioned electronic atomization device, since the delay of the switch module will affect the output power of the power module, the present application adjusts the duty cycle of the output power by obtaining the delay of the switch module, thereby improving the accuracy of the output power.
[0071] As an embodiment, the obtaining of the delay of the switch module in the electronic atomization device includes:
[0072] Acquire a first moment when a control signal is sent to the control end of the switch module and a second moment when a detection end in the electronic atomization processing module detects a change corresponding to the control signal;
[0073] The delay of the switch module is acquired according to the first moment and the second moment.
[0074] Specifically, this embodiment applies the control circuit of the output power of the electronic atomization device described in any of the above embodiments, and obtains the first moment of sending the control signal to the control end of the switch module through the clock module, and the second moment of the change corresponding to the control signal detected by the detection end of the processing module in the electronic atomization processing module, and then obtains the delay of the switch module according to the first moment and the second moment, that is, the delay of the switch module can be obtained by subtracting the first moment from the second moment.
[0075] As an embodiment, adjusting the duty cycle of the pulse signal according to the delay includes:
[0076] Obtaining a first duty cycle according to the delay and the frequency of the pulse signal output by the processing module;
[0077] The target duty cycle of the pulse signal is adjusted according to the first duty cycle.
[0078] Specifically, in the prior art, the target power is P, the corresponding frequency of the pulse signal PWM is f, the period is T=1 / f, the target duty cycle of the pulse signal PWM (i.e., the duty cycle before the pulse signal is adjusted) is d, and the delay of the switch module is △t. The first duty cycle = △t*f. If the delay obtained is the delay of the switch module being turned off, the target duty cycle of the adjusted pulse signal = d-△t*f; if the delay obtained is the delay from the switch module being turned on, the target duty cycle of the adjusted pulse signal = d+△t*f. That is, during the delay of the pulse signal switch module being turned off, the target duty cycle of the pulse signal is reduced; during the delay of the pulse signal switch module being turned on, the target duty cycle of the pulse signal is increased. It is understandable that in a specific implementation, the performance of different switch modules is different, that is, when the pulse signal changes from a low level to a high level, the delay of the switch module can be basically ignored (that is, the delay of the switch module turning on can be basically ignored), then there is no need to increase the target duty cycle of the pulse signal when the pulse signal changes from a low level to a high level; similarly, if the delay of the switch module can be basically ignored when the pulse signal changes from a high level to a low level, there is no need to reduce the target duty cycle of the pulse signal when the pulse signal changes from a high level to a low level, and the specific adjustment process can be set according to actual needs. Exemplarily, the PWM frequency is 3*10^4HZ (i.e. 30KHZ), and each cycle is 3.3*10^(-5) seconds (i.e. 33us). Assuming that the target output duty cycle is 50% and the MOSFET delay of the switching module is 5*10^(-6) seconds (i.e. 5us), the PWM output duty cycle corresponding to the target power is Duty=50%-5*10^(-6)*3*10^4=50%-15%=35%; in this way, as long as the PWM duty cycle is set to 35%, the target power output value can be achieved, thereby achieving the purpose of improving the output power accuracy.
[0079] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
[0080] Based on the same inventive concept, the embodiment of the present application also provides an electronic atomization device for realizing the control circuit and method of the electronic atomization device output power involved above. The implementation scheme for solving the problem provided by the electronic atomization device is similar to the implementation scheme recorded in the control circuit and method of the electronic atomization device output power described above. Therefore, the specific limitations in one or more electronic atomization device embodiments provided below can refer to the limitations of the control circuit and method of the electronic atomization device output power described above, and will not be repeated here.
