For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0040] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.
[0041] The existing products have the problem of low accuracy in detecting the resistance of the heating wire.
[0042] In this application, two switch modules are used to automatically clean impurities attached to the contact points by turning them on and off at different stages, thereby improving the accuracy of heating wire resistance detection.
[0043] like Figure 1 As shown, in some embodiments, a control circuit for an atomizing device is provided for detecting the resistance of an atomizer. This control circuit mainly includes a control module 10, a first output module 11, a second output module 12, and a sampling module 13. The control module 10 is used to output a first signal and a second signal in a time-division manner according to the connection status of the atomizer. The first output module 11, electrically connected to the control module 10, is used to output a first current according to the first signal. The second output module 12, electrically connected to the control module 10, is used to output a second current according to the second signal. The sampling module 13, electrically connected to the control module 10, is used to sample and detect the voltage value of the atomizer. Specifically, when the second signal is output, the atomizer receives the second current and is heated; when the first signal is output, the sampling module 13 samples the voltage of the atomizer and outputs a sampled value. The control module 10 obtains the resistance value of the atomizer based on the sampled value and the first current.
[0044] Exemplarily, the atomizing device control circuit 1 can be detachably electrically connected to the heating wire of the atomizer 2 via a ejector pin (i.e., a spring pin). When the atomizer 2 is inserted, the heating wire forms a complete circuit path with the atomizing device control circuit 1 of this embodiment through the ejector pin. The control terminal of the control module 10 is connected to the enable signal input terminals of the first output module 11 and the second output module 12 respectively, and outputs the first signal (enable signal of the first output module 11) and the second signal (enable signal of the second output module 12) in a time-division manner. For example, when the atomizer is determined to be inserted, the control module 10 can, in the first stage, output the second signal to turn on the second output module 12 and output a second current. The atomizer receives the second current and heats up. Since the second current is a high current higher than the first current, it can dissolve the oil on the heating wire. In the second stage, the first signal is sent to turn on the first output module and output the first current. At this time, the sampling module 13 samples the voltage of the atomizer and outputs the sampled value. The control module 10 can calculate the resistance value of the heating wire of the atomizer based on the sampled value and the first current.
[0045] This embodiment can output different signals in a time-division manner, allowing the parallel circuit links to output different currents in a time-division manner. The high current is output first to dissolve the oil on the heating wire, and then the resistance value is detected, thereby improving the detection accuracy.
[0046] Alternatively, the duration of the first phase can be longer than 1 microsecond, such as 1 microsecond, 2 microseconds, 3 microseconds, 5 microseconds, 7 microseconds, etc. The duration of the second phase can be between 10 microseconds and 10 milliseconds, such as 10 microseconds, 12 microseconds, 15 microseconds, 1 millisecond, 3 milliseconds, 4 milliseconds, 5 milliseconds, 6 milliseconds, 7 milliseconds, 9 milliseconds, 10 milliseconds, etc.
[0047] In some embodiments, a low-level signal can be set as an enable signal, or a high-level signal can be set as an enable signal. That is, the first signal and the second signal can both be low-level signals as the conduction control signals of the switching module, or both can be high-level signals as the conduction control signals of the output module. The following embodiments mainly use a low-level signal as an enable signal as an example to describe this application in detail.
[0048] In some embodiments, such as Figure 2 As shown, the first output module 11 includes a first switch module 20 and a voltage divider resistor R1, and the second output module 12 includes a second switch module 30. The first terminal of the first switch module 20 is connected to one terminal of the voltage divider resistor R1, and the enable signal input terminal of the first switch module 20 is connected to the control module 10 to receive a first signal. The other terminal of the voltage divider resistor R1 is configured to connect to the atomizer. The first terminal of the second switch module 30 is connected to the other terminal of the voltage divider resistor R1. The enable signal input terminal of the second switch module 30 is connected to the control module 10 to receive a second signal. Optionally, the control module 10 further includes an ADC module 101 connected to the sampling module 13. The sampling module 13 is connected to the other terminal of the voltage divider resistor R1 and is used to sample and detect the analog measurement voltage of the atomizer. The ADC module 101 is used to convert the analog measurement voltage to a digital measurement voltage, and the control module 10 obtains the resistance value of the atomizer based on the digital measurement voltage and the resistance value of the voltage divider resistor.
[0049] It is understood that the other end of the voltage divider resistor R1 can be detachably electrically connected to the heating wire of the atomizer 2 through a pin (i.e., a spring pin). When the atomizer 2 is inserted, the heating wire forms a complete circuit path with the atomization device control circuit of this embodiment through the pin. The first end of the second switch module 30 is connected to the other end of the voltage divider resistor R1, that is, the first end of the second switch module 30 is also detachably connected to the atomizer. The control terminal of the control module 10 is connected to the enable signal input terminals of the first switch module 20 and the second switch module 30, respectively. When the atomizer is inserted, the control module 10 can, in the first stage, send a second enable signal to the second switch module 30 to turn it on. In the second stage, the second switch module 30 is turned off, and a first enable signal is sent to the first switch module 20 to turn it on, and the resistance value of the heating wire of the atomizer is calculated according to the voltage divider principle.
[0050] For example, such as Figure 2 As shown, the sampling module 13 can be a signal line, which connects the other end of the voltage divider resistor R1 to the ADC module 101 in the control module 10. The control module 10 can obtain the analog measurement voltage of the heating wire through this signal line, and convert the analog measurement voltage into a digital measurement voltage. Based on the voltage divider principle, the actual resistance value of the heating wire is calculated. Figure 3 As shown, taking microcontroller U1 as an example, the R_ADC pin of microcontroller U1 is connected to the other end of the voltage divider resistor R1 through the signal line to obtain the analog measurement voltage of the heating wire, and the analog measurement voltage is converted from analog to digital to obtain the digital measurement voltage. The actual resistance value of the heating wire is calculated based on the voltage divider principle.
[0051] like Figure 2 As shown, in some embodiments, the control circuit may further include a protection resistor R4, through which the control module 10 is connected to the other end of the voltage divider resistor R1. In this embodiment, the protection resistor R4 prevents large currents from entering the control module 10, thus avoiding damage to the control module 10 and affecting its service life.
[0052] like Figure 2 As shown, in some embodiments, the control circuit further includes a power supply component 40, which is connected to the first output module 11 (or the second terminal of the first switch module 20) and the second output module 12 (or the second terminal of the second switch module 30). In this embodiment, the power supply component 40 can also be connected to the control module 10 to provide the control module 10 with normal operating voltage.
[0053] like Figure 2 As shown, in some embodiments, the control circuit further includes a pull-up resistor R5. One end of the pull-up resistor R5 is connected to the power supply component 40, and the other end is connected to the other end of the voltage divider resistor R1 and the control module 10. The control module 10 can determine whether the atomizer is inserted based on the level of the pull-up resistor R5. It can be understood that the microcontroller U1 determines the atomizer insertion status by detecting the high or low level of the R_IN pin. If the atomizer is not inserted, the R_IN pin detects a high level; if the atomizer is inserted, the R_IN pin detects a low level. That is, when the atomizer is inserted, the R_IN pin of the microcontroller U1 changes from a high level to a low level, thereby waking up the microcontroller U1, enabling it to execute the first and second stage control operations sequentially. Optionally, the pull-up resistor R5 can be a large resistor with a resistance of 1MΩ.
[0054] like Figure 2As shown, in some embodiments, the first switching module 20 includes a first MOSFET Q1, and the second switching module 30 includes a second MOSFET Q2. The gate of the first MOSFET Q1 is connected to the first control terminal of the control module 10, the source of the first MOSFET Q1 is connected to the power supply component 40, and the drain of the first MOSFET Q1 is connected to one end of the voltage divider resistor R1. The gate of the second MOSFET Q2 is connected to the second control terminal of the control module 10, the source of the second MOSFET Q2 is connected to the power supply component 40, and the drain of the second MOSFET Q2 is connected to the other end of the voltage divider resistor R1.
[0055] When the first enable signal (first signal) is high, the first MOSFET Q1 is off. When the first enable signal is low, the first MOSFET Q1 is on. When the second enable signal is high, the second MOSFET Q2 is off. When the second enable signal (second signal) is low, the second MOSFET Q2 is on.
[0056] As an option, such as Figure 2 As shown, the first output module 11 may further include a first current-limiting resistor R2 and a second current-limiting resistor R6, and the second switch output module may further include a third current-limiting resistor R3 and a fourth current-limiting resistor R8. The gate of the first MOSFET Q1 is connected to the first control terminal of the control module 10 via the first current-limiting resistor R2, and to the source of the first MOSFET Q1 via the second current-limiting resistor R6. The gate of the second MOSFET Q2 is connected to the second control terminal of the control module 10 via the third current-limiting resistor R3, and to the source of the second MOSFET Q2 via the fourth current-limiting resistor R8. In this embodiment, the current-limiting resistors mainly serve as current-limiting protection, preventing excessive current from the MOSFET from passing through the microcontroller U1, thereby damaging the controller and affecting its service life.
[0057] refer to Figure 3 In some embodiments, the control circuit may further include a voltage regulator and filter module 50, through which the power supply terminal of the control module 10 is connected to the power supply component 40. Exemplarily, the voltage regulator and filter module 50 may include a seventh resistor R7, a first capacitor C32, and a second capacitor C36. The power supply terminal of the control module 10 (VDD in the figure) is grounded via the first capacitor C32 and the second capacitor C36, and connected to the power supply component 40 (VCC in the figure) via the seventh resistor R7. Optionally, the voltage regulator and filter module 50 may also refer to related technologies.
[0058] by Figure 2 and Figure 4 Taking this as an example, the working principle of this application will be explained in detail below. Figure 4In the diagram, resistor R9 represents the heating wire of the atomizer, and control module 10 can be selected as microcontroller U1. When the atomizer is inserted into the main unit, OUT+ and OUT1+ are connected via a pin, and OUT- and OUT1- are connected via a pin. When EN1 (first enable signal) is high, the first MOSFET Q1 is not turned on; when EN1 is low, the first MOSFET Q1 is turned on. When EN2 (second enable signal) is high, the second MOSFET Q2 is not turned on; when EN2 is low, the second MOSFET Q2 is turned on.
[0059] When the atomizer is inserted, the R_IN pin of microcontroller U1 changes from high to low, waking up microcontroller U1 and executing the first stage: controlling the second MOSFET Q2 to conduct while the first MOSFET Q1 remains off for a period of time. Microcontroller U1 reads the AD value of the heating wire (R9) through the R_ADC pin, denoted as AD1. The actual resistance value of R9 is calculated using the voltage divider principle, where AD_MAX can be selected as a 12-bit ADC with a maximum value of 4095. It can be understood that when the second MOSFET Q2 is on and the first MOSFET Q1 is off, current flows from BAT+ through Q2 and R9, then to ground. The current I = VCC / R9, which is relatively large and can automatically clean oxides and dirt between the pins. When there is a large contact resistance between the pins due to oxides and impurities, the large current flowing through the pins when the second MOSFET Q2 is on increases the heat generated by the impurities, melting them and reducing the contact resistance, ultimately yielding an accurate actual resistance value of the heating wire.
[0060] When the first MOSFET Q1 is turned on and the second MOSFET Q2 is not turned on, the current flows from BAT+ through Q1, R1, and R9, and then to ground. The current I = VCC / (R1 + R9) is relatively small. At this time, U1 reads the AD value of R_ADC, which is denoted as AD1. VCC also serves as the ADC supply voltage for U1, and the maximum ADC value is denoted as AD_MAX. Therefore:
[0061] R9 / R1=(AD+1) / (AD_MAX-AD), where R1, AD1 and AD_MAX are known values, and R9, i.e., the actual resistance value of the heating wire, can be calculated from this.
[0062] refer to Figure 1 In some embodiments, an atomizing device is provided, which includes an atomizer 2 and an atomizing device control circuit 1 as described in the above embodiments. The atomizing device control circuit 1 is located inside the main unit. The atomizer 2 is provided with a heating wire, which is detachably connected to the atomizing device control circuit 1 via a pin. It can be understood that the other end of the voltage divider resistor R1 can be detachably electrically connected to the heating wire of the atomizer through the pin (i.e., a spring pin), that is, when the atomizer is inserted, the heating wire forms a complete circuit path with the resistance detection circuit of this embodiment through the pin.
[0063] It is understood that the atomizer 2 includes a cavity for loading the aerosol forming matrix, and a heating wire is disposed in the cavity to heat the aerosol forming matrix to generate aerosol. It can form a path with the detection circuit through the pin when the atomizer is inserted into the main unit.
[0064] This embodiment can output different signals in a time-division manner, that is, the parallel circuit links output different currents in a time-division manner, and the high current is output first to dissolve the oil on the heating wire before resistance detection is performed, thereby improving the detection accuracy.
