 [0042] Embodiment 1

 [0043] Please refer to FIG. 1 , the embodiment provides an electronic cigarette smoke atomization control method, the electronic cigarette includes a display module, a battery assembly, and an atomization assembly, and the battery assembly and the atomization assembly are To remove the connection, such as a plug or a threaded connection, the control method comprises the following steps:

[0044] Sl, when the battery component and the atomization component are connected to each other, identifying the type of the atomization component; [0045] S2, determining the atomization of the electronic cigarette based on the type of the atomization component Controlling the mode, and controlling the display module to display an atomization control interface corresponding to the atomization control mode, so that the user controls the adjustment in the atomization control mode according to the display information of the atomization control interface. The smoke oil atomization power or/and the atomization temperature of the electronic cigarette. Wherein, according to actual use requirements, the atomization control interface may have a function of displaying information and a function of receiving a touch instruction for controlling adjustment of the smoke atomization power or/and the atomization temperature. [0046] Specifically, please refer to FIG. 2, the step S1 specifically includes the following sub-steps:

 [0047] Sl, when the battery component and the atomizing component are connected to each other, determining whether the battery component and the atomizing component are in an effective connection state, and obtaining a first determination result;

 [0048] S12. When the first determination result is yes, identify the type of the atomizing component.

 [0049] In a specific implementation process, the electronic cigarette includes a microprocessor, and the microprocessor is provided with a connection determining pin for determining whether the battery component and the atomizing component are operatively connected; The battery assembly and the atomizing assembly are connected to each other, and the microprocessor determines whether an effective connection signal indicating that the battery component and the atomizing component are effectively connected is transmitted on the connection determining pin to determine the Whether the battery component and the atomizing component are operatively connected; wherein the effective connection signal is one of a high level signal, a low level signal, or an analog to digital conversion signal. For example, when the battery component and the atomization component are not operatively connected, the microprocessor detects that the connection determination pin is a low level signal, and when the connection determination pin is detected to be high Level signal 吋, determining that the battery component and the atomizing component are operatively connected; or, when the battery component and the atomizing component are not operatively connected, the microprocessor detects the connection determination a high level signal on the pin, when it is detected that the connection determining pin is a low level signal 吋, determining that the battery component and the atomizing component are operatively connected; or, when the battery component And the atomizing component is not operatively connected, the microprocessor detects that there is no analog-to-digital conversion signal on the connection determining pin, and when detecting that there is an analog-to-digital conversion signal on the connection determining pin, determining The battery assembly and the atomizing assembly are operatively connected.

[0050] In a specific implementation process, the type of the atomization assembly includes a temperature control type and a power control type. The temperature-controlled atomization component refers to: when the battery component supplies power to the atomization component and the power supply is stable, the temperature and resistance value of the heating wire for atomizing the smoke oil in the atomization component vary with the change of the power supply length. Specifically, without considering the external factors such as adding new oil and oil, when the power supply of the battery pack does not change, the temperature of the heating wire increases with the increase of the length of the power supply, and decreases with the length of the power supply. However, when it is necessary to maintain the temperature of the heating wire, it is necessary to constantly adjust the power supply of the battery component according to the current temperature of the heating wire. The power control type atomizing component refers to: When the battery component supplies power to the atomizing component and the power supply is stable, the resistance value of the heating wire remains substantially unchanged, and the temperature of the heating wire changes according to the power supply power of the battery component. Specifically, Under the premise of not considering the external factors such as adding new oil and oil, when the power supply of the battery pack increases, the temperature of the heating wire rises, when the power supply of the battery pack decreases, the temperature of the heating wire Reduce, when you need to maintain the temperature of the heating wire, you only need to keep the power supply of the battery pack unchanged. However, whether it is a temperature-controlled atomizing component or a power-controlled atomizing component, the temperature and resistance of the heating wire for atomizing the smoke oil therein may change during the initial stage of energization, and the resistance of the heating wire is blocked. The value varies with temperature; the "initial phase of energization" here refers to the stage in which the heating wire is never energized to the preset length of the energization (eg, 300 m S ~ 400 ms), at which stage, for the temperature-controlled mist For the component, the rate of change or the variation of the resistance value of the heating wire for atomizing the smoke oil with the temperature change is greater than or equal to a first preset value, and for the power control type atomization component, the inside thereof The rate of change or the magnitude of change of the resistance of the heating wire for atomizing the smoke oil with temperature is less than the first predetermined value. When the initial stage of energization ends, and the battery assembly continues to energize the atomization assembly with the same power, the temperature and resistance of the heating wire of the temperature control type atomization assembly still change, and the power control type atomization assembly The resistance of the heating wire is basically no longer changed.

 [0051] The step S1 is specifically: when the battery component and the atomization component are connected to each other, the battery component is controlled to continuously supply power to the atomization component for a predetermined length, and the atomization is acquired. Determining the rate of change or the magnitude of the change of the resistance of the heating wire for atomizing the smoke oil in the assembly. When the rate of change or the magnitude of the change is greater than or equal to the first predetermined value, determining that the atomizing component is the The temperature control type atomizing component determines that the atomizing component is the power control type atomizing component when the resistance change rate or the variation amplitude is less than the first preset value. Specifically, when the "change rate of the resistance of the heating wire with the temperature change" is used as a criterion, the first preset value is 6.25%, and the "resistance value of the heating wire varies with temperature" as a criterion.吋, the first preset value is 12.5 ηιΩ. For example, in general, the resistance of the heating wire is 0.2 Ω. When the resistance of the heating wire becomes 0.2125 Ω after the power is turned off for 350 ms, it is determined. The corresponding atomizing component is temperature controlled. If the resistance of the heating wire becomes 0.201 Ω, it is determined that the corresponding atomizing component is of a power control type. In addition, in the specific implementation process, after identifying the type of the atomizing component and obtaining the recognition result, the electronic cigarette will issue a prompt message, such as a light or a sound; of course, for different recognition results, the prompt message sent by the electronic cigarette can also be Different to facilitate user differentiation.

 [0052] Further, the step S2 includes:

[0053] when the atomization component is the temperature control type atomization component, determining that the atomization control mode of the electronic cigarette is the first control mode, and controlling the display module display output and the first control a first control interface corresponding to the mode, so that the user displays the first control according to the display information of the first control interface In a mode, a temperature of a heating wire for atomizing the smoke oil in the atomizing assembly is obtained, and a smoke atomization temperature of the electronic cigarette is adjusted based on a temperature control of the heating wire. The display information of the first control interface includes a temperature of a heating wire for atomizing the smoke oil in the atomizing assembly, an output power of the battery component, and a voltage of the battery component;

 [0054] when the atomization component is the power control type atomization component, determining that the atomization control mode of the electronic cigarette is a second control mode, and controlling the display module display output and the second control a second control interface corresponding to the mode, so that the user acquires the output power of the battery component in the second control mode according to the display information of the second control interface, and controls based on the output power of the battery component Adjusting the smoke atomizing power of the electronic cigarette. The display information of the second control interface includes a resistance of a heating wire for atomizing the smoke oil in the atomizing assembly, an output power of the battery assembly, and a voltage of the battery assembly.

 [0055] Specifically, the first control mode of the electronic cigarette refers to: detecting the current temperature of the heating wire by the electronic cigarette, and adjusting the power supply of the battery component according to the current temperature and the user demand, so as to realize the heating wire mist The adjustment of the temperature. The second control mode of the electronic cigarette means: the electronic cigarette detects the current power supply of the battery component, and adjusts the power supply of the battery component according to the user's demand, so as to realize the adjustment of the heating power of the heating wire. Further, when the atomization control mode of the electronic cigarette is determined to be the first control mode, the display module is controlled to display a first control interface including a temperature of the heating wire, an output power of the battery component, and a voltage of the battery component, when the electronic The atomization control mode of the smoke is determined to be the second control mode, and the display module is controlled to display a second control interface including a resistance of the heating wire, an output power of the battery component, and a voltage of the battery component, so that the user is based on the first control The information on the interface or the second control interface is targeted to input an operational command for adjusting the aerosolizing power or/and the atomizing temperature to the electronic cigarette.

[0056] Based on the above description, the display module of the electronic cigarette outputs different control interfaces according to different types of the atomizing components, and displays different information. Specifically, when the atomization component is the temperature control type atomization component, the display module displays and outputs a first control interface; when the atomization component is the power control type atomization component, The display module displays an output second control interface; further, for the electronic cigarette provided with the control interface switching function, it is capable of receiving and controlling the display module to switch display output the first control interface and the first Second control interface. For example, the battery component is provided with a switching button, the first button operation is received by the switching button, and the first The button operation is converted into a first electrical signal, so that the electronic cigarette controls the display module to switch display the working parameter information of the electronic cigarette based on the first electrical signal, and the working parameter includes a resistance of the heating wire and a heating wire. The temperature, the output power of the battery pack, and the voltage of the battery pack. In order to prevent the user from switching the control interface of the electronic cigarette display module to the atomization control interface that does not correspond to the atomization control mode during use, the user is inconvenient to use, and when the atomization component is the temperature control The atomizing component, and the electronic cigarette receives an operation command for controlling the display module to display and output the second control interface, the electronic cigarette outputs an alarm signal; or, when the atomizing component is The power control type atomizing assembly, and the electronic cigarette receives an operation command for controlling the display module to display and output the first control interface, and the electronic cigarette outputs an alarm signal. The alarm information may be specifically used to remind the user that the atomization control interface is incorrectly switched, such as text information, light information, or sound information, and is not specifically limited herein.

 [0057] In a specific implementation process, for the temperature-controlled atomization assembly, when the user smokes, the battery assembly supplies power to the atomization assembly, and the atomization temperature of the atomization assembly is a preset temperature (eg, 220). °C), For the power control type atomizing assembly, when the user smokes, the battery assembly supplies power to the atomizing assembly, and the atomizing power of the atomizing assembly is preset power (eg, 30 W). The electronic cigarette is further provided with an atomization control function for receiving and controlling the electronic cigarette to adjust the smoke atomization power or/and the atomization temperature based on a user's operation instruction. Specifically, the battery component is provided with an increase control button and a decrease control button. After the user smokes, the electronic cigarette receives the second button operation through the increase control button, and converts the second button operation into a second electrical signal. So that the electronic cigarette controls the electronic cigarette to increase the smoke atomization power or/and the atomization temperature based on the second electrical signal, and receives the third button operation by the reduction control button, and the The three-button operation is converted to a third electrical signal to cause the electronic cigarette to control the electronic cigarette to reduce the smoke atomization power or/and the atomization temperature based on the third electrical signal.

[0058] In the specific implementation process, the existing electronic cigarette still has technical problems that prevent the user from knowing whether the oil is about to be exhausted, and continues to smoke after the smoke oil is exhausted, thereby causing the problem of burning cotton, in the solution of the present application. The atomizing component is provided with a heating wire temperature real detecting module inside the temperature control type electronic cigarette. When the user needs to adjust the atomization temperature of the electronic cigarette oil, the heating wire for atomizing the smoke oil in the atomizing component is obtained. The temperature is such that the microprocessor in the electronic cigarette adjusts the power supply of the battery assembly based on the temperature value to achieve adjustment of the atomization temperature of the heating wire. Reasonable use of the heating wire temperature detection module can be solved The problem of burning cotton due to the exhaustion of the smoke oil is continued. Specifically, please refer to FIG. 3, the control method further includes:

 [0059] S3, for the electronic cigarette with the atomization component being temperature-controlled, after detecting the smoking signal, supplying power to the heating wire for atomizing the smoke oil in the atomizing assembly to operate the heating wire;

 [0060] S4. Acquire a temperature change speed of the heating wire, and determine that the smoke oil is exhausted in the electronic cigarette after the change speed is greater than a second preset value, and stop supplying power to the heating wire.

 [0061] Specifically, the specific heat capacity of the heating wire is not A, and the specific heat capacity of the smoke oil is B (greater than A), and the specific heat capacity of the smoke oil adhered to the heating wire is C, wherein C It is greater than A and less than B. It is known from the physical definition of specific heat capacity: Unit mass object changes the internal energy of absorption or release per unit temperature, that is, the specific heat capacity of the substance can directly reflect the temperature change rate. In the present embodiment, by detecting the temperature change rate of the heating wire, the current specific heat capacity of the heating wire can be known by the temperature change rate, that is, whether the heating wire adheres to the smoke oil. In other words, by determining whether the temperature change rate of the heating wire is greater than a second preset value, it is determined whether the current specific heat capacity of the heating wire is similar to the specific heat capacity of the heating wire without adhering the smoke oil, and the temperature change rate of the heating wire is greater than the second preset. The value 吋 indicates that the current specific heat capacity of the heating wire is similar to the heat capacity (A) of the heating wire itself, and thus the amount of smoke oil adhered to the heating wire is not adhered or the amount of the smoked oil is small, so that the fuel consumption of the electronic cigarette can be determined. End, and stop supplying power to the heating wire.

 [0062] Further, in a specific implementation process, the temperature values of the initial engraving and ending engraving of a certain preset inter-segment segment may be obtained, and the heating filaments may be calculated through the two temperature values and the preset inter-turn time. Referring to FIG. 4, the electronic cigarette is provided with an oil guiding member that is in contact with the heating wire and supplies oil to the heating wire, and the heating wire atomizes the oil on the oil guiding member to form Smoke, the step S4 specifically includes sub-steps

[0063] S41. Obtain a first temperature value of the heating wire in the first engraving;

 [0064] S42, when the temperature of the heating wire rises to a preset second temperature value 吋, obtaining a time required for the heating wire temperature to rise from the first temperature value to the second temperature value, wherein The second temperature value is less than or equal to a temperature value of the oil enthalpy of the oil guiding member;

[0065] S43. Calculate a temperature change speed of the heating wire based on the first temperature value, the second temperature value, and the turn, and the change speed is greater than the second preset value. And determining that the smoke oil in the electronic cigarette is exhausted to stop supplying power to the heating wire. [0066] It should be noted here that, in the above step S42, the temperature of the oil guiding member cracking crucible is the maximum temperature that the oil guiding member can withstand, and in a specific application, the oil guiding member can be heated to the beginning of discoloration. The temperature of the crucible is set to an upper limit of the second temperature value, and the temperature of the initial discoloration crucible may be different depending on the material of the oil guiding member, and is not specifically limited herein.
