In electronic cigarette products, the atomization temperatures of different types of e-liquids are different, and the differences in atomization temperatures of different types of e-liquids are large. In order to obtain a better atomization effect, it is necessary to be able to detect the starting atomization temperature and the optimal atomization temperature of different e-liquids, so as to control the temperature of the electronic atomization device according to the starting atomization temperature and the optimal atomization temperature of the e-liquid. Summary of the Invention
[0003] This application provides an atomization temperature recognition method, an atomization temperature recognition device, and a storage medium that can recognize the starting atomization temperature and the appropriate atomization temperature of an electronic atomization device.
[0004] To achieve the above object, the following technical solutions are provided:
[0005] An atomization temperature recognition method, applied to an electronic atomization device, includes the following steps:
[0006] Capture the temperature curve of the heating wire within a T time period;
[0007] The point at which the temperature curve changes from steep to gentle is recorded as the atomization starting point of the e-liquid in the electronic atomization device, and the point at which the temperature curve changes from gentle to a slope approaching 0 is recorded as the relatively suitable atomization point of the atomization liquid in the electronic atomization device.
[0008] In some embodiments, the change of the temperature curve from steep to gentle is judged by the slope change rate △k, and when the slope change rate △k drops by more than a predetermined range, it is considered that the temperature curve changes from steep to gentle.
[0009] In some embodiments, when the slope change rate △k drops by more than 20%, it is considered that the temperature curve changes from steep to gentle.
[0010] In some embodiments, the slope approaching 0 means that the slope is greater than or equal to 0 and less than or equal to 0.1.
[0011] In some embodiments, the capturing of the temperature curve of the heating wire within a T time period includes:
[0012] Heat the test electronic atomization device with the output power P, and capture the temperature curve of the heating wire within a T time period.
[0013] In some embodiments, the power P is 15w - 24w, and / or
[0014] The time period T is from 500 ms to 1000 ms.
[0015] In some embodiments, the power P is 20 w, and / or

[0017] After the step of, in some embodiments, marking the point at which the temperature curve changes from steep to gentle as the atomization start point of the e-liquid in the electronic atomization device, and marking the point at which the temperature curve changes from gentle to a slope approaching 0 as the more suitable atomization point of the atomization liquid in the electronic atomization device, the method further includes:
[0018] Writing the atomization start point and the more suitable atomization point into the storage unit of the electronic atomization device.
[0019] An atomization temperature recognition device applied to an electronic atomization device, comprising:
[0020] A grabbing module configured to grab the temperature curve of the heating wire within the T time period;
[0021] A temperature judgment module configured to mark the point at which the temperature curve changes from steep to gentle as the atomization start point of the e-liquid in the electronic atomization device, and mark the point at which the temperature curve changes from gentle to a slope approaching 0 as the more suitable atomization point of the atomization liquid in the electronic atomization device.

[0023] The atomization temperature recognition method of the embodiment of the present application grabs the temperature curve of the heating wire within the T time period, and identifies the temperature at which the atomization liquid in the electronic atomization device starts to atomize and the suitable atomization temperature from the temperature curve. Specifically, the point at which the temperature curve changes from steep to gentle is marked as the atomization start point of the atomization liquid, and the point at which the temperature curve changes from gentle to a slope approaching 0 is marked as the more suitable atomization point of the atomization liquid. In this way, the atomization start point and the more suitable atomization point of the atomization liquid can be identified, and then the temperature control of the electronic atomization device can be performed according to the atomization start point and the more suitable atomization point, so that the temperature control method of the electronic atomization device can adapt to various different atomization liquids and has an ideal control effect on various different atomization liquids. Description of the Drawings
[0024] Figure 1 It is a schematic flow chart of the atomization temperature recognition method in an embodiment of the present application;
[0025] Figure 2 It is a schematic diagram of the temperature curve in an embodiment of the present application. Detailed Embodiments
[0026] The following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.
[0027] This embodiment discloses a method for identifying atomization temperature. Figure 1 It is a flowchart of the method for identifying atomization temperature in an embodiment of the present application. In this embodiment, the method for identifying atomization temperature is applied to an electronic cigarette, and the atomization liquid described in the present application is the e-liquid of the electronic cigarette. Of course, the method for identifying atomization temperature in this embodiment can also be applied to other electronic atomization devices, which is not limited herein. As Figure 1 shown, the method for identifying atomization temperature in the embodiment of the present application includes the following steps:
[0028] S100. Capture the temperature curve of the heating wire within the time period T;
[0029] S200. The point at which the temperature curve changes from steep to gentle is recorded as the atomization start point of the e-liquid in the electronic atomization device, and the point at which the temperature curve changes from gentle to a slope approaching 0 is recorded as the more suitable atomization point of the atomization liquid in the electronic atomization device.
[0030] Specifically, the atomization temperatures of different types of e-liquids are different. In the embodiment of the present application, first, the temperature curve of the electronic cigarette for testing is captured, and the temperature curve within a period of time T is captured. By replacing different types of e-liquids or using electronic cigarettes filled with different types of e-liquids for testing, the temperature curves of different e-liquids can be obtained.
[0031] As Figure 2 shown. The temperature curve is a temperature-time curve graph, that is, a schematic diagram of the temperature of the heating wire of the electronic cigarette at different times. The horizontal axis is time, and the vertical axis is temperature. As Figure 2 shown, the temperature curve has a relatively steep section a, a relatively gentle section b, and a section c that tends to be flat.
[0032] As Figure 2 shown, at the intersection H1 of section a and section b is the atomization start point, that is, the point H1 at which the temperature curve changes from steep (section a) to gentle (section b) is recorded as the atomization start point of the e-liquid in the electronic atomization device.
[0033] At the intersection H2 of section b and section c is the more suitable atomization point, that is, the point H2 at which the temperature curve changes from gentle (section b) to a slope approaching 0 (section c) is recorded as the more suitable atomization point of the atomization liquid in the electronic atomization device.
[0034] Thus, the range between H1 and H2 is the atomization temperature range.
[0035] That is to say, section b forms a gently sloping upward interval. H1 is the starting point of the slope, that is, the starting point of atomization. H2 is the ending point of the slope, that is, the more suitable atomization point.
[0036] In one embodiment, in step S200, it is determined by the slope change rate △k that the temperature curve changes from steep to gentle. When the slope change rate △k drops by more than a predetermined range, it means that the temperature curve changes from steep to gentle.
[0037] Specifically, referring to Figure 2 , Figure 2 , the slope change rate △k of section a is relatively large, so that section a is relatively steep. After passing through point H1, the slope change rate △k of section b becomes much smaller, forming a turning point. The slope change rate △k of section b is relatively small, so that section b is relatively gentle. This turning point H1 is the temperature of the heating wire when the e-liquid starts to atomize. Therefore, the slope change rate △k dropping by more than a predetermined range can be used as the judgment criterion for the temperature curve to change from steep to gentle, and the atomization starting point H1 can be found through this condition.
[0038] The slope change rate △k is the second derivative of temperature with respect to time, and the slope k is the first derivative of temperature with respect to time.
[0039] Figure 2 There are many zigzag lines on the temperature curve in
[0040] . In actual processing, the curve can be processed into a smooth curve for judgment by a certain method. For example, some peak points can be removed by filtering.
[0041] Furthermore, when the slope change rate △k drops by more than 20%, it means that the temperature curve changes from steep to gentle. Figure 2 , from Figure 2 it can be seen that the slope change rate of section b curve is about half less than that of section a curve, that is, about 50%. In actual judgment, we take that the slope change rate △k drops by more than 20% as the temperature curve changes from steep to gentle, preferably 30%-70%.
[0042] In one embodiment, in step S200, the slope is close to 0, that is, the slope is greater than or equal to 0 and less than or equal to 0.1.
[0043] Specifically, in step S200, when finding the more suitable atomization point H2, that is, when finding the turning point H2 from section b to section c, it is judged by the temperature curve changing from gentle (section b) to a slope close to 0 (section c). In this embodiment, when the slope k is close to 0, the slope k is taken as greater than or equal to 0 and less than or equal to 0.1, that is, 0≤k≤0.1.
[0044] Specifically, when looking for the atomization starting point H1 and the more suitable atomization point H2, several points can be found for verification calculations to ensure the accuracy of the calculations. For example, if several consecutive points satisfy that the slope change rate △k drops by more than 20%, it is determined that the atomization starting point H1 has been found. If several consecutive points satisfy that the slope k is close to 0, it is determined that the more suitable atomization point H2 has been found.
[0045] In one embodiment, step S100 includes:
[0046] Heat the test electronic atomization device with the output power P, and capture the temperature curve of the heating wire within the time period T.
[0047] Specifically, when capturing the temperature curve, a test electronic cigarette can be prepared, and the temperature curve can be captured by heating the test electronic cigarette with the power P through the host computer.
[0048] In one embodiment, the power P is 15w - 24w. The time period T is 500ms - 1000ms. Preferably, the power P is 20w. The time period T = 500ms. When capturing the temperature curve, a point can be captured every 3 - 7ms to form the temperature curve. Preferably, a point is captured every 5ms. A point can also be captured every 3ms, 4ms, or 6ms, 7ms.
[0049] In a specific embodiment of the present application, the atomization temperature recognition method includes the following process:
[0050] A. Output the power P = 20w to the test electronic atomization device, and capture the temperature curve of the heating wire within the time period T = 500ms;
[0051] B. The point at which the slope change rate △k on the temperature curve drops by more than 50% is the atomization starting point H1. The temperature curve starts to climb gently from the atomization starting point H1, and the point at which the slope k is close to 0 is the more suitable atomization point H2.
[0052] In one embodiment, after step S200, it further includes:
[0053] S300. Write the atomization starting point and the more suitable atomization point into the storage unit of the electronic atomization device.
[0054] Specifically, the above steps S100 and S200 can be performed on the host computer. After capturing the temperature curve of the test electronic cigarette through the host computer and finding the atomization starting point H1 and the more suitable atomization point H2 of the e - liquid, write the atomization starting point H1 and the more suitable atomization point H2 into the storage unit of the electronic cigarette, and perform temperature control on the electronic cigarette according to the atomization starting point H1 and the more suitable atomization point H2, so as to perform reasonable control for different e - liquids and automatically take into account and be compatible with the control of multiple e - liquids.
[0055] The above atomization temperature recognition method can also be used to distinguish the types of e-liquid temperatures. Because different types of e-liquids have different atomization temperatures.
