     Referring to  FIG. 1 ,  FIG. 1  is a schematic structural diagram of a first embodiment of an electronic vaporization device according to this application. The electronic vaporization device  10  includes an air pressure sensor  11 , a processor  12 , and a vaporization module  13 . The processor  12  is connected to the air pressure sensor  11  and the vaporization module  13 , to respectively control operation of the air pressure sensor  11  and the vaporization module  13 . 
     The vaporization module  13  is configured to vaporize an aerosol-forming substrate (for example, tobaccos or e-liquid) to generate vapor, and a vaporization form may be pressure vaporization, electromagnetic vaporization, or ultrasonic vaporization, which is not specifically limited herein. An airflow channel communicating the inside and the outside is disposed in the electronic vaporization device  10 , and the generated vapor is inhaled from the airflow channel. It may be understood that, in this embodiment, intake of the aerosol-forming substrate is detected. 
     The air pressure sensor  11  is disposed in the airflow channel and configured to obtain an air pressure value in the airflow channel, so that the processor  12  can obtain the air pressure value and calculate the intake of the aerosol-forming substrate based on the air pressure value. 
     Referring to  FIG. 2 ,  FIG. 2  is a schematic structural diagram of a second embodiment of an electronic vaporization device according to this application. 
     Optionally, in an embodiment, the electronic vaporization device  10  further includes a reminding module  14  connected to the processor  12 . The processor  12  is configured to calculate the intake of the aerosol-forming substrate according to the air pressure value in the airflow channel obtained by the air pressure sensor  11 , and control the corresponding reminding module  14  to remind a user according to the intake. For example, the reminding module  14  may be a speaker, a display screen, or an LED light. In an embodiment, the user may be reminded by using the reminding module  14  when the detected intake is greater than a preset threshold. 
     Optionally, in another embodiment, the processor  12  is further configured to adjust operating parameters of the electronic vaporization device  10  according to the intake. For example, the processor  12  may adjust a power, a temperature, or an operation time of the vaporization module  13  according to the intake. 
     Optionally, in another embodiment, the electronic vaporization device  10  further includes a detection component  15  connected to the processor  12 . The detection component  15  is configured to detect a type of the aerosol-forming substrate, namely, to recognize a specific type of the aerosol-forming substrate. Under the same inhaling force, intake brought by different types of aerosol-forming substrates are also different. Therefore, the intake of the aerosol-forming substrate obtained through calculation is modified by using the processor  12 , to obtain more accurate intake. The detection component  15  may be a code scanner, and the aerosol-forming substrate may be solid-state tobaccos or liquid-state e-liquid, which is not required herein. The foregoing process may be described in detail in the following embodiments. Referring to  FIG. 1 ,  FIG. 2 , and  FIG. 3 ,  FIG. 3  is a schematic flowchart of a first embodiment of a method for detecting intake of an aerosol-forming substrate according to this application. The method for detecting intake of an aerosol-forming substrate in this embodiment includes the following steps: 
     Step S 301 : Obtain an air pressure value in an airflow channel of an electronic vaporization device. 
     After the vaporization module  13  starts working and generates vapor, the air pressure sensor  11  obtains an air pressure value in the airflow channel of the electronic vaporization device  10 . In an inhaling process of a user, the air pressure value in the airflow channel of the electronic vaporization device  10  changes due to an inhale action of the user, so that the air pressure value is monitored in real time within a set time period. In this embodiment, the air pressure sensor  11  may be a pressure sensor, a venturi sensor, a pore plate, a Dall tube, an anemometer, a porous pressure probe, a cone flowmeter, or a turbine flowmeter. 
     Step S 302 : Calculate intake of an aerosol-forming substrate according to the air pressure value. 
     After the air pressure value in the airflow channel is obtained by the air pressure sensor  11 , a total amount of the aerosol-forming substrate inhaled by the user within a set time period is calculated according to the air pressure value. The set time period may be a time period in which the user completes one inhaling process, or may be a time period in which a plurality of inhaling processes are completed, which is not specifically limited. This process may be described in detail in the following embodiments. 
     Step S 303 : Remind a user according to the intake, or adjust operating parameters of the electronic vaporization device according to the intake. 
     According to the calculated total amount of the aerosol-forming substrate inhaled by the user within the set time period, when the intake meets a preset condition, the processor  12  controls the reminding module  14  to remind the user, or the processor  12  adjusts the power or the set time period of the electronic vaporization device  10  according to the total amount of the intake, to control the intake of the aerosol-forming substrate of the user. 
     The reminding module  14  may be a speaker, a display screen, an LED light, or a vibration motor, and the user is reminded of excessive inhaling intake and temperance is required by these components through prompt sound, displayed information, illumination, or vibration. The reminding module  14  may further be a mobile device such as a smart phone or a wearable smart device that is in a communication connection with the electronic vaporization device  10 . The processor  12  may further generate information about the intake into a report and transmit the report to the foregoing mobile device, so that information such as an inhaling frequency within a time period of the user may be further viewed while the user is reminded. 
     In a specific embodiment, the preset condition may be reminding the user when the total amount of the intake is greater than an intake threshold. In another embodiment, the preset condition may alternatively be reminding the user when the intake is less than another intake threshold. In this case, content reminded to the user may be informing the user that the electronic vaporization device  10  may fail or a better level of the electronic vaporization device  10  is insufficient, so that the aerosol-forming substrate is reduced or the aerosol-forming substrate needs to be replaced. 
     Different from the related art, the method for detecting intake of an aerosol-forming substrate provided in this application includes: obtaining an air pressure value in an airflow channel of an electronic vaporization device; calculating intake of the aerosol-forming substrate according to the air pressure value; and reminding a user according to the intake, or adjusting operating parameters of the electronic vaporization device according to the intake. According to the foregoing method, the air pressure value in the airflow channel of the electronic vaporization device is obtained, and the intake of the aerosol-forming substrate in the electronic vaporization device is accurately detected according to the air pressure value, so that inhaling intake of a user is controlled and the user is reminded. 
     Referring to  FIG. 1 ,  FIG. 2 , and  FIG. 4 ,  FIG. 4  is a schematic flowchart of a second embodiment of a method for detecting intake of an aerosol-forming substrate according to this application. The method for detecting intake of an aerosol-forming substrate in this embodiment includes the following steps: 
     Step S 401 : Receive a trigger instruction. 
     The processor  12  receives a trigger instruction transmitted by the user, and the trigger instruction may be a button trigger instruction, a touch trigger instruction, an inhale trigger instruction, or an action sensing trigger instruction. 
     The button trigger instruction and the touch trigger instruction may be implemented by using a specific button disposed outside the electronic vaporization device  10 . When the user performs a press or touch action on the button, the button transmits a trigger instruction to the processor  12 . 
     The inhale trigger instruction may be implemented by detecting whether the air pressure value in the airflow channel of the electronic vaporization device  10  changes by using the air pressure sensor  11 . When the user performs an inhale action, the air pressure sensor  11  may change, and in this case, the air pressure sensor  11  transmits a trigger instruction to the processor  12 . 
     The action sensing trigger instruction may be implemented by using a camera disposed outside the electronic vaporization device  10 . A posture of the user is recognized by using the camera, for example, if the camera recognizes a slide or a gesture toward a direction, the camera transmits a trigger instruction to the processor  12 . 
     Step S 402 : Drive, in response to the trigger instruction, a vaporization module of an electronic vaporization device to work at a constant power or a constant temperature, to generate vapor. 
     After the processor  12  receives the trigger instruction transmitted by the user, the vaporization module  13  of the electronic vaporization device  10  is driven to work at a constant power or a constant temperature to generate vapor, and the vapor is generated through vaporization of the aerosol-forming substrate in the electronic vaporization device. 
     In a use process of a common electronic vaporization device, the vaporized aerosol-forming substrate may not be completely inhaled by the user, and the intake of the aerosol-forming substrate inhaled by the user is generally affected by factors such as a power, a temperature, a type of the aerosol-forming substrate, an inhale time, and airflow pressure. Therefore, the electronic vaporization device  10  using a constant power or a constant temperature during outputted is required. In this case, amounts of aerosol-forming substrates generated by using the same electronic vaporization device  10  are basically the same. 
     Step S 403 : Obtain an air pressure value in an airflow channel of the electronic vaporization device. 
     After the vaporization module  13  starts working and generates vapor, the air pressure sensor  11  obtains an air pressure value in the airflow channel of the electronic vaporization device  10 . 
     Optionally, in some embodiments, step S 403  may further include: obtaining at least one real-time air pressure value in the airflow channel of the electronic vaporization device  10  within a set time period according to a set frequency. 
     The air pressure value in the airflow channel of the electronic vaporization device  10  may be increased or decreased due to an inhale action of the user, so that there are a plurality of different air pressure values within the set time period. The air pressure sensor  11  acquires the plurality of different actual air pressure values in the airflow channel in real time according to a certain set frequency. The set frequency may be 50 Hz to 100 Hz, namely, an interval time for obtaining different air pressure values is 10 milliseconds to 20 milliseconds. The set frequency is not specifically limited and may be adjusted according to the set time period. 
     Step S 404 : Calculate intake of an aerosol-forming substrate according to the air pressure value. 
     Step S 405 : Remind a user according to the intake, or adjust operating parameters of the electronic vaporization device according to the intake. 
     Optionally, in some embodiments, step S 405  may further include: when a total amount of the intake is greater than a preset intake threshold, stopping vaporization of the vaporization module  13  in the electronic vaporization device  10  or reducing a vaporization power of the vaporization module  13 . 
     Specific implementation steps of step S 403  to step S 405  are the same as those of the foregoing step S 301  to step S 303 , and details are not described herein again. 
     Different from the related art, the method for detecting intake of an aerosol-forming substrate provided in this application includes: obtaining an air pressure value in an airflow channel of an electronic vaporization device; calculating intake of the aerosol-forming substrate according to the air pressure value; and reminding a user according to the intake, or adjusting operating parameters of the electronic vaporization device according to the intake. According to the foregoing method, the air pressure value in the airflow channel of the electronic vaporization device is obtained, and the intake of the aerosol-forming substrate in the electronic vaporization device is accurately detected according to the air pressure value, so that inhaling intake of a user is controlled and the user is reminded. 
     Referring to  FIG. 1 ,  FIG. 2 , and  FIG. 5 ,  FIG. 5  is a schematic flowchart of a third embodiment of a method for detecting intake of an aerosol-forming substrate according to this application. The method for detecting intake of an aerosol-forming substrate in this embodiment includes the following steps: 
     Step S 501 : Obtain an air pressure value in an airflow channel of an electronic vaporization device. 
     After the vaporization module  13  starts working and generates vapor, the air pressure sensor  11  obtains a real-time air pressure value in the airflow channel of the electronic vaporization device  10  within a set time period according to a set frequency. 
     Step S 502 : Calculate an air pressure difference value between at least one real-time air pressure value and a standard atmospheric pressure, to obtain at least one air pressure difference value. 
     It may be understood that, when an inhale action within a set time period starts, the air pressure value in the airflow channel and the standard atmospheric pressure is the same (similar). As the inhale action starts, vapor in the airflow channel is inhaled, and the air pressure value in the airflow channel gradually decreases. When the inhale action stops, the air pressure value in the airflow channel reaches a minimum value, and the air pressure value then continues to rise. When the inhale action ends, the air pressure value in the airflow channel is restored to the standard atmospheric pressure, and such an inhale cycle is performed for a plurality of times. Therefore, in this step, after at least one real-time air pressure value in the airflow channel of the electronic vaporization device  10  within the set time period is obtained according to the set frequency, an air pressure difference value between each real-time air pressure value and the standard atmospheric pressure is calculated to obtain at least one air pressure difference value, so that total intake of the user within the set time period may be reflected. 
     Step S 503 : Calculate, when there is only one air pressure difference value, corresponding intake of an aerosol-forming substrate according to the air pressure difference value; or calculate, when there are at least two air pressure difference values, corresponding intake of the aerosol-forming substrate according to each air pressure difference value, and accumulate the intake of the aerosol-forming substrate corresponding to the at least two air pressure difference values, to obtain the intake of the aerosol-forming substrate within a set time period. 
     When there is only one air pressure difference value obtained through calculation, the intake of the aerosol-forming substrate within the set time period is directly calculated according to the air pressure difference value. 
     When there are at least two air pressure difference values obtained through calculation, after an air pressure difference value between one real-time air pressure value and the standard atmospheric pressure within the set time period is obtained, the intake of the aerosol-forming substrate inhaled by the user is calculated according to the air pressure difference value, and the intake of the aerosol-forming substrate corresponding to a plurality of air pressure difference values is accumulated, to obtain a total amount of the intake of the aerosol-forming substrate within the set time period. 
     The set time period may be a time period in which the user completes one inhale action, namely, a time period from the user transmits a trigger instruction to enable the vaporization module  13  to work to the end of the working. Alternatively, the set time period may be a specific quantity of inhale actions, for example, the set time period may be completion of 10 inhale actions. It should be noted that, air pressure difference values obtained by the 10 inhale actions is obtained by multiplying an inhale time by an air pressure sampling frequency, and there may be far more than 10 air pressure difference values. In addition, the set time period may start to time from a time when the electronic vaporization device  10  starts to work, a time period such as 5 minutes is preset, and intake of the aerosol-forming substrate corresponding to all real-time air pressure values within the 5 minutes is calculated. 
     In a specific embodiment, the intake of the aerosol-forming substrate may be calculated by using the following formula: Δm=c(Σ i=1   i=n (aP+b)), and according to this formula, the total amount of the aerosol-forming substrate inhaled by the user within the set time period may be integrated. There may be one or a plurality of different air pressure values at the set frequency, so that the calculation accuracy of the intake of the aerosol-forming substrate may be improved. 
     When there is only one air pressure difference value obtained through calculation, n=1; Δm is the intake of the aerosol-forming substrate, namely, a total amount of the intake of the aerosol-forming substrate inhaled by the user within a set time period; p is the air pressure difference value, namely, an air pressure difference value between one real-time air pressure value and a standard atmospheric pressure at the set frequency; a, b, and c are set parameters, a and b are associated with the power and the air pressure difference value of the electronic vaporization device  10 , when the electronic vaporization device works at a constant power or a constant temperature, a and b may change along with changes of the air pressure value in the airflow channel of the electronic vaporization device  10 , and a and b may be the same or may be different under different air pressures; and c is associated with a type of the aerosol-forming substrate, and the type of the aerosol-forming substrate may be recognized by using the detection component  15  to obtain the set parameter c. 
     In this formula, there is a deterministic relationship between the intake Δm of the aerosol-forming substrate and the air pressure difference value p, and an approximate curve of the relationship is shown in  FIG. 6 . From the perspective of the entire image, the intake Δm of the aerosol-forming substrate increases as the air pressure difference value p increases, and in different air pressure difference value ranges, amplitudes increased by the intake Δm may be different. For example, in a range from 200 Pa to 400 Pa of the air pressure difference value p, as the air pressure difference value p increases, an increase amplitude of the intake Δm is much greater than increase amplitudes in other air pressure difference value ranges. Calculation may be performed according to the formula in an entire air pressure range or may be performed segment by segment, for example, 0 to 100 Pa corresponds to one curve, 100 Pa to 200 Pa corresponds to another curve, and the rest may be deduced by analogy. 
     Optionally, in some embodiments, the detection method in this application may further include: obtaining a type of the aerosol-forming substrate; and determining the associated parameter c based on the type of aerosol-forming substrate. 
     The electronic vaporization device  10  includes a cartridge. The cartridge is in a detachable connection to help the user to replace e-liquid, namely, the aerosol-forming substrate. Different types of aerosol-forming substrates may produce different aerosol-forming substrates, a cartridge of each type of aerosol-forming substrate has a unique identifier, and the identifier may be an image or a chip such as two-dimensional code or bar code that can be recognized, to represent different types of aerosol-forming substrates. The detection component  15  stores information including types of aerosol-forming substrates in advance, and the detection component  15  obtains the type of aerosol-forming substrate by recognizing the identifier on the cartridge. The processor  12  determines the associated parameter c in the foregoing formula according to the type of the aerosol-forming substrate. 
     The following table shows values obtained by performing actual tests according to the foregoing formula, and as can be seen from the data, the accuracy can meet most applications.

     Step S 504 : Remind a user according to the intake, or adjust operating parameters of the electronic vaporization device according to the intake. 
     A specific implementation of step S 504  is the same as that of step S 303 , and details are not described herein again. Different from the related art, the method for detecting intake of an aerosol-forming substrate provided in this application includes: obtaining an air pressure value in an airflow channel of an electronic vaporization device; calculating intake of the aerosol-forming substrate according to the air pressure value; and reminding a user according to the intake, or adjusting operating parameters of the electronic vaporization device according to the intake. According to the foregoing method, the air pressure value in the airflow channel of the electronic vaporization device is obtained, and the intake of the aerosol-forming substrate in the electronic vaporization device is accurately detected according to the air pressure value, so that inhaling intake of a user is controlled and the user is reminded. 
     Referring to  FIG. 7 ,  FIG. 7  is a schematic structural diagram of a computer storage medium according to an embodiment of this application. The computer storage medium  70  stores a computer program  71 , and the computer program  71 , when executed by the processor  12 , is configured to implement the following method: 
     obtaining an air pressure value in an airflow channel of an electronic vaporization device, the airflow channel being configured for vapor generated by the electronic vaporization device to flow for ease of inhaling, the vapor being generated through vaporization of an aerosol-forming substrate in the electronic vaporization device; calculating intake of the aerosol-forming substrate according to the air pressure value; and reminding a user according to the intake, or adjusting operating parameters of the electronic vaporization device according to the intake. 
     Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: receiving a trigger instruction; and driving, in response to the trigger instruction, a vaporization module of the electronic vaporization device to work at a constant power or a constant temperature, to generate the vapor. 
     Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: obtaining at least one real-time air pressure value in the airflow channel of the electronic vaporization device within a set time period according to a set frequency; calculating an air pressure difference value between the at least one real-time air pressure value and a standard atmospheric pressure, to obtain at least one air pressure difference value; calculating, when there is only one air pressure difference value, corresponding intake of the aerosol-forming substrate according to the air pressure difference value; or calculating, when there are at least two air pressure difference values, corresponding intake of the aerosol-forming substrate according to each air pressure difference value, and accumulating the intake of the aerosol-forming substrate corresponding to the at least two air pressure difference values, to obtain the intake of the aerosol-forming substrate within the set time period. 
     Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: calculating the intake of the aerosol-forming substrate by using the following formula: Δm=c(Σ i=1   i=n (aP+b)), where Δm is the intake of the aerosol-forming substrate, p is an air pressure difference value, a, b, and c are set parameters, a and b are associated with a power and the air pressure difference value of the electronic vaporization device, and c is associated with a type of the aerosol-forming substrate. 
     Optionally, calculation of the intake of the aerosol-forming substrate may be performed by using a linear calculation method, a table lookup method, a power function method, a logarithmic function method, or a linear calculation and compensation method. 
     This solution is intended to find a differential relationship between the intake of the aerosol-forming substrate and an inhale pressure difference. The relationship is m=f(p) if represented by using a mathematical function, where m is the intake of the aerosol-forming substrate, p is the inhale pressure difference, and the function may be calculated based on theory or based on experience. Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: obtaining a type of the aerosol-forming substrate; and determining the associated parameter c based on the type of aerosol-forming substrate. 
     Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: reminding a user when the intake is greater than a preset intake threshold. 
     Optionally, in another embodiment, the computer program, when executed by the processor, is further configured to implement the following method: when the intake is greater than a preset intake threshold, stopping vaporization of a vaporization module in the electronic vaporization device or reducing a vaporization power of the vaporization module. 
     In the several implementations provided in this application, it should be understood that the disclosed method and device may be implemented in other manners. For example, the described device embodiment is merely exemplary. For example, the division of the modules or units is merely a logical function division and may be other division during actual implementation. For example, a plurality of units or components may be combined or integrated into another system, or some features may be ignored or not performed. 
     The units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, and may be located in one place or may be distributed over a plurality of network units. Some or all of the units may be selected according to actual requirements to achieve the objectives of the solutions of the implementations. 
     In addition, functional units in the implementations of this application may be integrated into one processing unit, or each of the units may exist alone physically, or two or more units may be integrated into one unit. The integrated unit may be implemented in the form of hardware, or may be implemented in a form of a software functional unit. 
     When the integrated unit in other implementations is implemented in the form of a software functional unit and sold or used as an independent product, the integrated unit may be stored in a computer-readable storage medium. Based on such an understanding, the technical solutions of this application essentially, or the part contributing to the related art, or all or some of the technical solutions may be implemented in the form of a software product.
