detailed description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In order to solve the technical problem that the heating temperature of the heating type electronic cigarette has insufficient control accuracy in the conventional technology, in this embodiment, a heating temperature control method based on the electronic cigarette is proposed, and the implementation of this method can depend on In a computer program, the computer program can run on a computer system based on the Von Neumann system. The computer program can be an application program based on the heating temperature control of an electronic cigarette device, for example, integrated in a single-chip microcomputer of an electronic cigarette rod Control program for controlling heating temperature.

Specifically, the implementation and execution of the above-mentioned electronic cigarette-based heating temperature control method are based on an electronic cigarette device. The electronic cigarette device may be an electronic cigarette rod of a heating type electronic cigarette, which may contain a smokeable material such as cut tobacco, and may The smokable material is heated for suction by a user. As shown in FIG. 1, the electronic cigarette device includes a heating circuit, and the heating circuit includes a heating element, and the heating element may be a heating resistor, for example, a thermistor or a load resistor. In addition, the heating element is powered by a heating circuit, so that the heating electrons generate heat to heat the smokable material placed in the electronic cigarette device for users to smoke. It should be noted that, in this embodiment, the power supply of the heating circuit is realized by PWM (Pulse Width Modulation, pulse width modulation) output, that is, the power supply circuit connected to the heating circuit outputs heating pulses to heat the heating circuit. The circuit is powered, that is, the input of the heating circuit is connected to the PWM output (ie, the output of the power supply circuit).

It should be noted that in this embodiment, different PWM pulse widths correspond to different output powers, so that the output power of the heating circuit is also different. Therefore, when the power of the heating circuit needs to be adjusted, the PWM The pulse width is adjusted to the power of the heating circuit, thereby achieving the adjustment of the temperature of the heating element.

Specifically, as shown in FIG. 2, the foregoing electronic cigarette-based heating temperature control method includes the following steps S102-S108:

Step S102: Receive an input heating temperature control instruction, and determine a target temperature value corresponding to the heating temperature control instruction.

The heating temperature control instruction is an instruction received by the control unit of the electronic cigarette device to control the temperature of a heating element (for example, a heating resistor) included in the electronic cigarette device. This instruction is used to instruct the control unit to adjust the power supply output (for example, the duty ratio of the PWM output) in the electronic cigarette device, so as to achieve the purpose of controlling the temperature of the heating element.

Generally speaking, the heating temperature control instruction includes the specific temperature value (target temperature value) for temperature control, or the direction and amplitude of temperature adjustment, and can be set according to the specific application scenario.

Specifically, in an optional embodiment, a physical button (or a peripheral button) is provided on the electronic cigarette device, and the user can input a corresponding heating temperature control instruction through the button, for example, when the button is in the first position In the case of heating, the preset first temperature is used as the target temperature value for heating, and when the button is in the second position, the preset second temperature is used as the target temperature value for heating. In addition, in other embodiments, the pressing operation corresponding to the heating temperature control instruction may also correspond to different pressing times, frequencies, and the like, and according to the preset correspondence between the pressing operation and the heating temperature control instruction, it is detected that After the pressing operation input through the peripheral button, a heating temperature control instruction corresponding to the detected pressing operation is determined, so that the control unit can control the corresponding module of the electronic cigarette device to perform related operations according to the heating temperature control instruction.

In another optional embodiment, the electronic cigarette device is further provided with a communication module (for example, a limited communication module, a WIFI module, a Bluetooth module, a Zigee module, etc.), and the electronic cigarette device can communicate with other terminals through the communication module. The device establishes a communication connection, and the related devices communicate through the communication connection (for example, data transmission, instruction transmission, etc.). In a specific embodiment, the electronic cigarette device can establish Bluetooth communication with a mobile terminal (for example, a mobile phone) through a Bluetooth module (Bluetooth chip), and the mobile phone and the electronic cigarette device can communicate through the established Bluetooth communication. Perform specific information exchange.

The user can control the heating temperature of the electronic cigarette device through the terminal device connected to the electronic cigarette device, for example, the heating temperature control instruction can be input through an APP corresponding to the electronic cigarette device installed on the terminal device.

In the application scenario shown in FIG. 3, FIG. 3 shows an application scenario of a control APP of an electronic cigarette device installed on a mobile phone. The user can input the corresponding target temperature value or adjust the amplitude through the input box of the target temperature adjustment as shown in Fig. 3. After detecting the user's operation, the mobile phone obtains the text entered by the user in the input box to generate heating. The temperature control command is sent to the electronic cigarette device.

In the case where the heating target temperature control instruction includes the final target temperature value to be adjusted, the corresponding target temperature value can be obtained directly from the heating temperature control instruction; if the heating temperature control instruction includes temperature adjustment In the case of direction and amplitude, obtain the corresponding temperature adjustment direction and amplitude, and determine the target temperature value in this adjustment according to the currently set heating temperature value.

Step S104: Acquire a current temperature value of the heating element.

In a specific embodiment, because a heating element is generally a resistor and a thermistor for a heating element, it corresponds to different resistance values under different temperature conditions, that is, the resistance value and There is a one-to-one correspondence between heating temperatures. Therefore, in this embodiment, the current resistance value of the heating element can be obtained by measuring the resistance value.

In a specific embodiment, the step of obtaining the current temperature value of the heating element further includes steps S1021-S1022 as shown in FIG. 4:

Step S1021: detecting a current resistance value at both ends of the heating element;

Step S1022: Determine a temperature value corresponding to the current resistance value as the current temperature value according to a preset temperature resistance correspondence relationship between the resistance value and the temperature value.

That is, in this embodiment, the calculation of the temperature is performed by measuring the resistance value of the resistor, and the heating resistor itself is a thermistor, so the temperature can be obtained by measuring the resistance value of the heating resistor.

In a specific embodiment, the resistance and temperature of the heating resistor can be measured by a circuit as shown in FIG. 5. As shown in Figure 5, RL is the load (heating component), and the R_DET_EN terminal is usually low voltage. When the load resistance RL is detected, R_DET_EN is controlled by the chip to high voltage, Q1 is turned on, and the chip reads both ends of the sampling resistor R1 ( The voltages from A and B), that is, the ADC values at V_OUT and V_OUT_DET are N ₁ and N _{2 respectively} . After reading, the R_DET_EN terminal is low voltage to close Q1, and then pass

Calculate the load resistance value, and then calculate the corresponding temperature based on the temperature-resistance relationship of the heating element that makes the load. This temperature is the current temperature value of the heating element.

In this embodiment, the purpose of detecting the current temperature value of the heating resistor is to control the heating temperature of the electronic cigarette, and in order to improve the control accuracy, the current temperature value needs to be detected in real time or at a higher frequency. For example, in one embodiment, in order to improve the effectiveness and accuracy of temperature control, the step of obtaining the current temperature value of the heating resistor is periodically performed according to a preset time period value, for example, according to a 100 mS The above step S102 is executed periodically.

Step S106: Determine a target PWM adjustment mode corresponding to the heating temperature control instruction according to the target temperature value and the current temperature value.

As mentioned earlier, the adjustment of the heating temperature of the electronic cigarette device is embodied by the adjustment of the duty cycle of the PWM output. In addition, when considering how to adjust the PWM output, it is necessary to consider both the current temperature and the difference between the target temperature and the specific value, as well as the current PWM duty cycle. Therefore, in When determining the specific adjustment of the PWM duty cycle adjustment currently required, the temperature adjustment situation needs to be determined according to the foregoing and current temperature values, and a preset target temperature value, and the current duty cycle value of the PWM output needs to be determined. Target duty cycle adjustment value for PWM duty cycle adjustment. For example, the target duty cycle adjustment value may be a target value for adjusting the PWM duty cycle in this adjustment.

In a specific embodiment, the above step S106 further includes steps S1062-S1064 as shown in FIG. 6:

Step S1062: detecting that the current duty ratio of the PWM output terminal is the current duty value;

Step S1064: Determine a target duty cycle adjustment value according to the current duty cycle value, the current temperature value, and the target temperature value, and use the target duty cycle adjustment value as the target PWM adjustment mode.

The output PWM duty cycle determines the output power, that is, different PWM duty cycles correspond to different heating powers for the heating circuit, that is, different heating temperatures. Therefore, when there is a gap between the current temperature value and the preset target temperature value, the output power can be controlled by controlling the PWM duty cycle to achieve the control of the heating temperature.

For the control and adjustment of the PWM duty cycle, the current situation of the PWM duty cycle needs to be known first, and then the PWM duty cycle is adjusted.

In this embodiment, the detection of the current PWM duty cycle is performed by measuring the current PWM duty cycle of the PWM output terminal, that is, the current duty cycle value.

In a specific embodiment, the PWM adjustment mode is the process of adjusting the duty cycle of the PWM output of the electronic cigarette device, and the next step is to adjust the target duty cycle adjustment value of the PWM adjustment.

Step S108: Adjust the heating temperature of the heating element of the electronic cigarette device according to the target PWM adjustment mode.

After the target PWM adjustment mode is determined, the PWM output from the PWM output terminal of the electronic cigarette device can be adjusted according to the target PWM adjustment mode.

Specifically, in a specific embodiment, the above-mentioned adjusting the heating temperature of a heating element of the electronic cigarette device according to the target PWM adjustment method further includes: adjusting the electronic device according to the target duty cycle adjustment value. The PWM output from the PWM output of the cigarette device is adjusted.

That is, after the target duty cycle adjustment value is determined, the PWM output at the PWM output terminal can be adjusted according to the target duty cycle adjustment value, that is, the magnitude of the PWM duty cycle after adjustment is the target occupation Air ratio adjustment value.

It should be noted that the target temperature value is a preset temperature value for optimal suction taste. For example, the target temperature value can be set to 320 degrees, or the user can also customize settings according to his own requirements for suction taste. The target temperature value, for example, for users who like heavy taste, you can set a higher target temperature value, such as 360 degrees.

As follows, the specific process of adjusting the PWM duty cycle can be determined according to the current duty cycle and the specific size and situation of the current temperature value.

In a specific embodiment, when the current temperature value is greater than the target temperature value and the first difference value exceeds a preset difference threshold value, obtaining a duty of the current output of the PWM output terminal The ratio is a buffered duty cycle value; the target duty cycle adjustment value is set to 0.

That is, in the case where the current duty cycle value D _N-1 ≠ 0 and the current temperature value T _N-1 > T _t + T _E (where T _t is the target temperature value and T _E is the preset difference Value threshold), set the target duty cycle adjustment value to 0, that is, clear the PWM output to 0, in order to reduce the temperature of the heating element.

After the duty cycle is 0 or the duty cycle is set to 0, in the process of determining a target duty cycle adjustment value according to the current duty cycle value, the current temperature value, and a preset target temperature value, The specific process of adjusting the PWM duty cycle is: when the current duty cycle value is 0 and the acquired current temperature value is less than or equal to the target temperature value, adjusting the target duty cycle The value is set to the buffer duty cycle value.

In other words, before clearing the PWM duty cycle, the specific size of the current PWM duty cycle needs to be stored, so that when the specific value of the PWM duty cycle is set later, it can be determined that it is closer to the target temperature value. The PWM duty cycle improves the user experience. Therefore, when the duty cycle is 0, if the detected current temperature value is greater than or equal to the target temperature value, the PWM duty cycle is maintained at 0; if the detected current temperature value is less than or equal to the target temperature value , You need to adjust the PWM duty cycle. Therefore, set the target duty cycle adjustment value to the buffered duty cycle value, that is, the value of the stored duty cycle before the last time the PWM duty cycle was cleared. .

That is, when the current duty cycle value D _N-1 = 0 and the current temperature value T _N-1 <T _t (where T _t is the target temperature value), the target duty cycle adjustment value D _{N is} set For the buffered duty cycle value D ′, the PWM duty cycle is adjusted to a size corresponding to the buffered duty cycle value D ′, so as to control the heating temperature of the electronic cigarette around the optimal target temperature.

In another optional embodiment, when the current temperature value is less than or equal to the target temperature value and the duty cycle is not 0, the foregoing according to the current duty cycle value and the current temperature value, the preset target temperature The process of determining the target duty cycle adjustment value by value is: calculating the temperature difference between the target temperature value and the current temperature value as the first difference value, and according to the correspondence between the preset difference value and the quantized value To obtain a first difference quantization value corresponding to the first difference value, and the first difference quantization value is a value between 0 and 1; and obtaining the target temperature value and The quantized value corresponding to the obtained temperature difference value of the heating temperature value is used as the second difference quantized value; and the quantized value is determined according to the current duty cycle value, the first difference quantized value, and the second difference quantized value Target duty cycle adjustment value.

And, the determining the target duty cycle adjustment value according to the current duty cycle value, the first difference quantization value, and the second difference quantization value is specifically:

According to formula

D _N = D _N-1 + 2E _N -E _N-1

Calculate the target duty cycle adjustment value, where D _N is the target duty cycle adjustment value, D _N-1 is the current duty cycle value, E _N is the first difference quantization value, and E _N-1 is the second difference The value is quantized.

That is, if the current duty cycle value is not 0, and the current temperature value is less than the target temperature value or does not exceed a certain range of the target temperature (for example, less than 5 ° C greater than the target temperature value), the PWM duty cycle The ratio is adjusted, but the amplitude of the adjustment is the current duty cycle value plus twice the difference quantization value, and subtracting the previous difference quantization value. The difference quantization value is a quantization value between 0 and 1 based on the difference between the detected current temperature value and the target temperature value. For example, if the difference value is 5 ° C, the difference is The value quantization value is set to 2%.

It should be noted that, in this embodiment, the first difference quantization value E _N represents the difference between the detected current temperature value and the target temperature value in this adjustment (that is, the N-th adjustment). The corresponding difference quantization value; the second difference quantization value E _N-1 represents the difference between the detected current temperature value and the target temperature value in the current adjustment (that is, the N-1th adjustment or the last adjustment). The difference quantization value corresponding to the difference.

As mentioned earlier, the determination of the target duty cycle adjustment value can be determined according to the following formula:

In other words, when the current PWM duty cycle is not 0 and the current temperature of the heating resistor does not exceed a certain range of the target temperature, the adjustment range of the PWM duty cycle is added to the original PWM duty cycle. The twice the quantized value of the temperature difference detected during the current adjustment and subtracting the quantized value of the temperature difference detected during the last adjustment is PID (proportion-integral-derivative, ratio, integral, Differential control) adjustment. When the temperature of the heating resistor exceeds a certain range of the target temperature, the PWM duty cycle is set to 0; and when the current PWM duty cycle is not 0, the specific value of the PWM duty cycle is obtained as a buffer value. . After the PWM duty cycle is cleared, when the temperature of the heating resistor drops to the target temperature, the PWM duty cycle before the price is cleared is restored and the PID adjustment is restarted.

In a specific embodiment, the correspondence between the difference between the current temperature value and the target temperature value, and the difference quantization value may be used. For example, it may be a linear function, a non-linear function, or a step function. .

In a specific embodiment, in order to avoid the burden caused by frequent PWM duty cycle adjustments caused by slight temperature differences on the electronic cigarette processor, the difference between the current temperature value and the target temperature value The corresponding relationship between the and quantization values of the difference can be a step function. For example, use the following function definition:

Among them, E is the difference quantization value, and ΔT is the difference between the target temperature value and the current temperature value, that is: ΔT = T _t -T _N.

In other embodiments, the correspondence between the difference between the current temperature value and the target temperature value, and the difference quantization value can be any positive correlation function.
