[0062] The object of the present invention is to provide a method for measuring the amount of atomized oil in an electronic cigarette, an electronic cigarette and a microprocessor, which can calculate the amount of atomized oil in an electronic cigarette by obtaining the puffing pressure and puffing time during the puffing, thereby realizing effective measurement of the amount of atomized oil in an electronic cigarette.

[0063] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0064] See also Figure 1 The present invention provides a method for measuring the atomization amount of an electronic cigarette, wherein the electronic cigarette includes an atomizer, and the method for measuring the atomization amount of an electronic cigarette includes the following steps:

[0065] 100. Acquire suction pressure information during suction;

[0066] 200. Get the puffing duration;

[0067] 300. Calculate an atomization rate of the atomizer based on the suction pressure information;

[0068] 400. Calculate the amount of oil mist atomized by the suction according to the atomization rate and the suction time.

[0069] This embodiment obtains information about the puff pressure and puff duration of the electronic cigarette during inhalation. The atomizer's atomization rate is then calculated based on the puff pressure information. The corresponding amount of oil vapor atomized is then calculated based on the atomization rate and puff duration, effectively measuring the amount of electronic cigarette atomized. The amount of oil vapor atomized is proportional to the nicotine content, so measuring the amount of oil vapor atomized indirectly determines the nicotine content of the inhaled cigarette, thus preventing excessive nicotine intake.

[0070] It should be noted that the puff duration in this embodiment may be the duration of a single puff or the sum of multiple puffs. In the following embodiments, the method for measuring the atomization amount of electronic cigarette is described in detail using the puff duration of a single puff as an example.

[0071] In some embodiments, the electronic cigarette further includes an air pressure sensor, which can be used to detect the inhalation pressure of the electronic cigarette in real time to obtain inhalation pressure information. In this embodiment, the inhalation pressure is detected and obtained by using the existing air pressure sensor in the electronic cigarette, thereby effectively measuring the amount of oil vaporized in the electronic cigarette without any additional hardware costs.

[0072] In some embodiments, see Figure 2 , step 200 specifically includes:

[0073] 210. Obtain a first interrupt signal output by the air pressure sensor and start timing;

[0074] 220. Obtain a second interrupt signal output by the air pressure sensor and stop timing;

[0075] 230. Obtain a first time value for starting timing and a second time value for stopping timing;

[0076] 240. Subtract the second time value from the first time value to obtain the puff duration.

[0077] In this embodiment, when the air pressure sensor in the electronic cigarette detects an increase in pressure, it indicates that the puffing has started, and accordingly a first interrupt signal will be output. Then, timing is started by obtaining the first interrupt signal. When the air pressure sensor detects that the suction pressure has increased to a certain value and no longer increases, it indicates that the puffing has ended, and the air pressure sensor will output a second interrupt signal. Then, timing is stopped after obtaining the second interrupt signal. Then, the first time value for starting timing and the second time value for stopping timing are obtained, and the puffing duration is obtained by subtracting the second time value from the first time value. At the same time, the pressure value detected by the air pressure sensor when the suction pressure increases to a certain value and no longer increases can be used as the suction pressure information, which is equivalent to using the maximum pressure value detected by the air pressure sensor as the suction pressure information. The suction pressure information is obtained to facilitate the subsequent calculation of the amount of oil mist vaporization.

[0078] In some embodiments, see Figure 3 , step 300 specifically includes:

[0079] 310. Obtaining the atomization power of the atomizer according to the suction pressure information;

[0080] 320. Obtain the temperature change value of the atomizer during the puffing time;

[0081] 330. Calculate the atomization rate based on the atomization power and temperature change value.

[0082] The principle of e-cigarette smoke generation is that the e-liquid vaporizes in the atomizer into high-temperature steam that is ejected toward the opening. The steam expands and condenses in the atmosphere into smoke-like droplets, forming smoke similar to that of traditional cigarettes. The temperature of the atomizer changes during the puffing process, and this temperature change corresponds to the heating temperature of the e-liquid. By obtaining the temperature change of the atomizer during the puffing time, and then based on the atomization power and temperature change, the atomization rate can be calculated.

[0083] In one embodiment, calculating the atomization rate based on the atomization power and the temperature change value includes calculating the atomization rate using a first formula, the first formula being: v = P / (C*ΔT*ρ), where v is the atomization rate, P is the atomization power, C is the specific heat capacity of the e-liquid, ΔT is the temperature change value, and ρ is the density of the e-liquid.

[0084] It should be noted that when the oil smoke is heated to a certain temperature, energy will be released. The released energy is denoted as J, then J = C*m*ΔT, because P*t = J, if t = 1 then P = J, that is, the atomization power of the atomizer per unit time and the energy released by the oil smoke during heating per unit time are equal. Therefore, when t = 1, J = C*m*ΔT = P, then m = P / (C*ΔT), and because the atomization rate is the volume atomized per unit time, then v = m / ρ. Then, combined with m = P / (C*ΔT), we get v = P / (C*ΔT*ρ). Among them, m is the mass of the oil, and ρ is the density of the oil. If it is assumed that the density of the oil is 1, then v = P / (C*ΔT). The specific oil density can be based on the parameters provided by the actual electronic cigarette manufacturer, and the present invention is not limited to this.

[0085] As an example, see Figure 4 , step 310 specifically includes:

[0086] 311. Calculating a suction pressure value based on the suction pressure information;

[0087] 312. According to the suction pressure value, a preset table is searched to obtain the atomization power corresponding to the suction pressure value. The preset table stores the corresponding relationship between the suction pressure value and the atomization power.

[0088] When the e-cigarette is not being inhaled, the pressure detected by the air pressure sensor is normal pressure, or atmospheric pressure. When the e-cigarette is inhaled, the air pressure sensor detects an increase in pressure. The maximum pressure value detected by the air pressure sensor is used as the inhalation pressure information. The inhalation pressure value is then subtracted from the normal pressure to obtain the inhalation pressure value. The atomization power corresponding to this inhalation pressure value is then obtained by looking up the table to facilitate the subsequent calculation of the oil mist atomization volume. The corresponding relationship between the inhalation pressure value and the atomization power stored in the table is the atomization power corresponding to different inhalation pressure values when achieving the optimal taste, as determined through experiments.

[0089] As another example, see Figure 5 , step 310 specifically includes:

[0090] 313. Calculating a suction pressure value based on the suction pressure information;

[0091] 314. Obtain preset power parameters;

[0092] 315. The atomization power is calculated based on the suction pressure value and the preset power parameter.

[0093] In this embodiment, the relationship between the atomization power corresponding to different puff pressure values when achieving the optimal flavor is quantified through experiments. The preset power parameter is the coefficient value of the atomization power corresponding to different puff pressure values when achieving the optimal flavor, obtained through experiments. The preset power parameter is λ, the puff pressure value is F, and the atomization power is P. Then, the obtained puff pressure value can be calculated using the second formula to obtain the corresponding atomization power. The second formula is P = λF.

[0094] Furthermore, in some embodiments, step 400 specifically includes integrating the atomization rate according to the puff duration to obtain the amount of liquid atomized. After obtaining the atomization rate, this embodiment integrates the atomization rate over the puff duration to obtain the amount of liquid atomized, thereby achieving measurement of the amount of liquid atomized in the electronic cigarette.

[0095] Furthermore, in some embodiments, after detecting the amount of oil vaporized, when the measured amount of oil vaporized exceeds a certain threshold, the e-cigarette's built-in display or vibration function will prompt the user to control the amount of smoking. Of course, a corresponding e-cigarette control app can also be set up on the mobile phone. When the measured amount of oil vaporized exceeds a certain threshold, it can also be transmitted to the mobile phone app to serve as a prompt, allowing a more intuitive understanding of the current amount of oil vaporized, thereby preventing excessive nicotine intake.

[0096] Further, see Figure 6 In some embodiments, step 310 further includes:

[0097] 410. Determine whether the atomization power of the atomizer is different from the preset atomization power;

[0098] 510. If the atomization power of the atomizer is different from the preset atomization power, adjust the atomization power of the atomizer to the preset atomization power.

[0099] In this embodiment, after obtaining the atomizer's atomization power, the atomizer power is compared with a preset atomization power, where the preset atomization power is the atomization power corresponding to the optimal flavor obtained through experiments. By comparing the atomizer's atomization power with the preset atomization power, if the atomizer's atomization power differs from the preset atomization power, the atomizer's atomization power is adjusted to the preset atomization power to ensure the optimal flavor.

[0100] As an embodiment, step 330 includes: adjusting the voltage and / or current of the atomizer so that the atomization power of the atomizer is a preset atomization power. That is, in this embodiment, when adjusting the atomization power of the atomizer, it can be achieved by adjusting the atomizer voltage or the atomizer current, or it can be achieved by adjusting the atomizer voltage and current simultaneously.

[0101] Further, see Figure 7 The present invention also provides an electronic cigarette, which includes a cigarette rod 1 and a cigarette cartridge 2. The cigarette rod 1 includes a microprocessor 10, and the cigarette cartridge 2 includes an atomizer 20. The microprocessor 10 is connected to the atomizer 20; the microprocessor 10 is used to execute the above-mentioned electronic cigarette atomization amount measurement method. Since the electronic cigarette atomization amount measurement method has been described in detail above, it will not be repeated here.

[0102] Further, see Figure 8 The present invention also provides a microprocessor 11, which is applied to an electronic cigarette. The electronic cigarette includes an atomizer 12, wherein the microprocessor 11 includes a first port A for obtaining suction pressure information during inhalation; a second port B for obtaining the duration of inhalation; and a processing unit for calculating the atomization rate of the atomizer 12 according to the suction pressure information, and calculating the amount of oil mist inhaled according to the atomization rate and the duration of inhalation.

[0103] In some embodiments, the microprocessor 11 further includes a third port C for outputting a control signal for adjusting the voltage and / or current of the atomizer 12. The current or voltage of the atomizer 12 can be adjusted by a power controller 14. The microprocessor 11 outputs a control signal to the power controller 14, which then adjusts the current or voltage of the atomizer 12, thereby effectively adjusting the atomization power of the atomizer 12.

[0104] In this embodiment, the first port A and the second port B can be connected to an air pressure sensor 13 external to the microprocessor 11. The air pressure sensor 13 transmits puff pressure information to the first port A and outputs an interrupt signal to the second port B. The microprocessor 11 then determines the puff duration based on the interrupt signal. The first port A and the second port B can also be the same port, that is, the air pressure sensor 13 is connected to a port of the microprocessor 11. The microprocessor 11 can then receive both the interrupt signal and the puff pressure information through this port.

[0105] In addition, the microprocessor 11 is also connected to an external power controller 14 via the third port C. The microprocessor 11 outputs a control signal to the power controller 14 via the third port C. The power controller 14 adjusts the current and / or voltage of the atomizer 12 according to the control signal, thereby achieving the effect of adjusting the atomization power of the atomizer 12.

[0110] Calculate the atomization rate of the nebulizer based on the suction pressure information;

[0111] The amount of oil mist puffed is calculated based on the atomization rate and the puffing time.

[0112] In this embodiment, an air pressure sensor detects the puff pressure during inhalation, and a timer measures the puff duration based on the interrupt signal from the air pressure sensor. Subsequently, a microprocessor calculates the atomization rate of the atomizer based on the puff pressure information. The amount of oil vaporized is calculated based on the atomization rate and the puff duration, thereby achieving the function of measuring the amount of oil vaporized in the electronic cigarette. It should be noted that the timer in this embodiment can also be integrated into the microcontroller.

[0113] Furthermore, in some embodiments, the electronic cigarette further includes a power controller; the power controller is connected to the microprocessor and is used to adjust the voltage of the atomizer and / or the current of the atomizer according to the control signal output by the microprocessor, thereby achieving the adjustment of the atomization power of the electronic cigarette.
