The real-time detection of such tiny quality and volume is difficult to realize, and particularly, the atomization device can have vibration, environment temperature and humidity change and other processes in the using process. Therefore, accurate measurement techniques are of interest.

When the temperature of the heating element meets a first preset condition, the atomization process of the heating element is stable, the energy absorbed by the heating element can be regarded as a constant, the influence of the temperature change of the heating element on the atomization amount can be not considered, and the calculation of the atomization amount is related to the output power, the output time and the gas flow.

Specifically, the temperature of the heating body includes an initial temperature and an atomization temperature; the absolute value of the difference between the initial temperature and the first preset temperature is smaller than a first threshold, the absolute value of the difference between the atomization temperature and the second preset temperature is smaller than a second threshold, and the temperature of the heating body meets a first preset condition.

In one embodiment, the electronic device is an electronic atomization device, and the structure of the electronic device will be described in detail by taking the electronic atomization device as an example. Referring to fig. 6, fig. 6 is a block diagram illustrating an electronic atomization device according to an embodiment of the disclosure.

The electronic atomizer comprises an atomizing assembly 1 and a power supply assembly 2. The atomizing assembly 1 comprises a liquid storage cavity 11 and a heating element 12, wherein the liquid storage cavity 11 is used for storing aerosol generating substrate, and the heating element 12 is used for atomizing the aerosol generating substrate stored in the liquid storage cavity 11. The power supply module 2 includes a processor 21 and a battery 22, the battery 22 supplies electric power to the heat-generating body 12, and the processor 21 controls whether the battery 22 supplies electric power to the heat-generating body 12.

The electronic atomization device further comprises an airflow channel (not shown), one end of the airflow channel is communicated with the outside atmosphere, and the outside atmosphere carries the aerosol atomized by the heating element 12 away through the airflow channel and reaches the mouth of a user. The power supply module 2 further includes an airflow sensor (not shown) disposed in the airflow path; the airflow sensor is used for detecting a suction signal, and the processor 21 controls the heating body 12 to work according to the suction signal detected by the airflow sensor. The air flow channel generates negative pressure when a user sucks, the pressure in the air flow channel is detected through the air flow sensor, and a suction signal is generated; the suction signal is an electrical signal, and the airflow sensor detects negative pressure and generates the negative pressure.

The atomizing assembly 1 and the power supply assembly 2 may be detachably connected or may be integrally formed, and are selected according to requirements.

The electronic atomization device can be used for atomizing liquid substrates such as nicotine-containing solution and liquid medicine. It will be appreciated that the aerosol-generating substrate stored in the reservoir 11 may be a liquid substrate, such as a nicotine-containing solution, a drug solution, or the like, and may be selected as desired. When the aerosol generating substrate is liquid medicine, the content of the atomized aerosol inhaled by a user needs to be accurately measured, and certain adverse reactions caused by too little inhalation amount and too much inhalation amount, which cannot achieve the effect of inhalation treatment, are avoided. When the aerosol-generating substrate is a nicotine-containing solution, a user is helped to use the electronic atomising device reasonably and cost-effectively by accurately measuring the amount of aerosol inhaled.

The principle of any one of the above methods for calculating the atomization amount will be described by taking an electronic atomization device as an example. Referring to fig. 7, fig. 7 is a schematic diagram of a calculation method of an atomization amount according to an embodiment of the present application.

The embodiment of the application detects the atomization amount by adopting the energy conservation principle in the heating atomization process. The total energy input during the atomization process may be represented by the output power and output time of the battery 22. The total energy input is divided into three parts to be consumed: the energy absorbed by the aerosol-generating substrate, the heat-generating body 12 and the energy conducted into the aerosol-generating substrate by the heat-generating body 12, the aerosol generated by the atomisation and the exchange of energy by the hot air within the airflow pathway (e.g. the energy of a structure heated by the airflow). It will be appreciated that the energy absorbed by the aerosol-generating substrate may cause the aerosol-generating substrate to be atomised to produce an aerosol; the heat generating element 12 and the energy conducted by the heat generating element 12 into the aerosol-generating substrate are collectively referred to as the energy absorbed by the heat generating element 12; the energy exchange of the aerosol generated by atomization and the hot air in the airflow channel is collectively referred to as the energy exchange associated with the airflow.

Since the larger the gas flow rate is, the shorter the gas residence time in the gas flow channel is, and the less the related heat exchange amount is, that is, the heat exchange process is related to the gas flow rate under the condition of the same gas flow channel structure. The pressure in the gas flow channel can also be related to the gas flow rate under the condition that the structure of the gas flow channel is kept unchanged, namely, the heat exchange process is related to the pressure change in the gas flow channel. Thus, the energy exchange associated with the gas flow may be described by the flow of gas or the change in pressure of the gas in the gas flow passage. The heat-generating body 12 and the energy conducted by the heat-generating body 12 into the aerosol-generating substrate may be described in terms of the change in temperature of the heat-generating body 12 and the thermal conductivity of the material of the heat-generating body 12. The energy absorbed by the aerosol-generating substrate includes the vaporisation energy required to produce the aerosol and the energy to raise the temperature of the aerosol as it is vaporised, i.e. the sensible and latent heat of the aerosol. The vaporization energy required by aerosol generation can be calculated by the input total energy and the energy output of each aspect, and the accurate atomization amount is obtained by obtaining the vaporization energy required by aerosol generation; that is, the energy absorbed by the aerosol-generating substrate may be described in terms of the amount of atomisation.

For an electronic atomisation device to atomise the same aerosol-generating substrate, the thermal conductivity of the aerosol-generating substrate, and the thermal capacity of the aerosol-generating substrate are fixed. In calculating the total energy input, the output power and output time of the battery 22 are collected. In the process of calculating the energy exchange related to the airflow, for the same electronic atomization device, the setting mode of the airflow channel is the same, that is, the heat exchange coefficients of the aerosol and the hot air with the side wall of the airflow channel are fixed, and the calculation of the energy related to the airflow only needs to collect the gas flow or the air pressure change in the airflow channel. In the process of calculating the energy absorbed by the heating body 12, for the same kind of electronic atomization device, the arrangement mode of the heating body 12 is the same, that is, the external dimension of the heating body 12 and the thermal conductivity of the material of the heating body 12 are fixed, and the energy absorbed by the heating body 12 only needs to be calculated by collecting the temperature of the heating body 12. Preferably, the temperature of the surface of the heat generating body 12 on which the heat generating member is located is collected to calculate the energy absorbed by the heat generating body 12.

Since the volume of aerosol that a user can draw is related to the volume of the mouth or lungs and the time of one draw, the gas flow rate can be described by the ratio of the volume of the mouth or lungs to the time of one draw. The volume of the mouth or lungs between different users is comparable and, therefore, the volume that can be aspirated by the user during aspiration is comparable. The time for which the user takes a puff satisfies the third predetermined condition, without considering the effect of the energy exchange associated with the air flow, described by the air flow, on the amount of atomization. When the temperature of the heating element 12 satisfies the first preset condition, the atomization process of the heating element 12 is stable, and the influence of the temperature change of the heating element 12 on the atomization amount can be disregarded. When the output power meets the second preset condition, the total energy of the input described by the output power and the output time can be simplified to be described by only the output time.

Referring to fig. 8, fig. 8 is a graph illustrating a comparison result between an atomization amount calculated by a preset algorithm and an actual atomization amount according to an embodiment of the present application.

The atomization parameters comprise output power, output time, temperature of the heating element 12 and gas flow, and the atomization amount is calculated by utilizing a first preset algorithm based on the output power, the output time (from power-on time to power-off time during suction), the temperature of the heating element 12 and the gas flow. In one embodiment, the output time t is designed to be 1s, 2s, 3s, 4s and 5s respectively, the suction capacity is designed to be 30ml, 60ml and 90ml respectively, the crossover experiment is carried out, a plurality of groups of atomization parameter samples and atomization amount samples corresponding to each group of atomization parameter samples are collected, and the atomization parameter samples comprise output power samples, output time samples and gas flow samples. A first preset algorithm is obtained by performing function fitting or training a model by using a plurality of groups of atomization parameter samples and the atomization amount samples corresponding to each group of atomization parameter samples, and a comparison result of the atomization amount and the actual atomization amount calculated by using the first preset algorithm is shown in fig. 8. As can be seen from fig. 8, the method for calculating the atomization amount provided in the embodiment of the present application can calculate the atomization amount relatively accurately.

Referring to fig. 9, fig. 9 is a schematic partial structure view of an electronic atomization device according to an embodiment of the present disclosure.

The electronic atomization device also comprises a flow sensor or a pressure sensor 4 arranged in the airflow channel, and the flow sensor or the pressure sensor 4 is connected with the processor 21 and used for detecting the gas flow. Further, the airflow channel flows through the atomizing chamber, and the flow sensor or the pressure sensor 4 is arranged in the airflow channel at the upstream relative to the atomizing chamber, so as to avoid the influence of the atomized aerosol on the long-term use of the flow sensor or the pressure sensor 4 (the aerosol is condensed and deposited on the flow sensor or the pressure sensor 4, and the detection accuracy of the aerosol is influenced).

The electronic atomization device also comprises a temperature sensor 3 arranged on the heating element 12, the temperature sensor 3 is connected with the processor 21 and used for detecting the temperature of the heating element 12, and the heating element 12 is controlled by the processor 21 to generate heat. Optionally, the temperature sensor 3 is embedded in the heating surface of the heating element 12, and a heating element is disposed on the heating surface, that is, the temperature sensor 3 is embedded in the surface of the heating element 12, so as to measure the surface temperature of the heating element 12.

In another embodiment, the heating element 12 may be configured to have TCR performance, the temperature of the heating element 12 may be obtained based on the TCR performance of the heating element 12, the processor 21 may obtain the temperature of the heating element 12 by converting the resistance value of the heating element 12, and the heating element 12 may be controlled by the processor 21 to generate heat. Specifically, the heating element of the heating element 12 has TCR performance, and both the internal temperature of the heating element 12 and the surface temperature of the heating element 12 (the temperature of the surface of the heating element 12 on which the heating element is provided) can be converted by the heating element resistance value of the heating element 12; it can be understood that the surface temperature of the heating body 12 is more accurately obtained by conversion using the resistance value of the heating element of the heating body 12 than the internal temperature of the heating body 12.

In the present embodiment, the processor 21 integrates a function of acquiring the output power and the output time of the battery 22. In other embodiments, the electronic atomization device further includes an output power detection unit and an output time detection unit; the output power detection unit is used for acquiring the output power of the battery 22 and transmitting the output power to the processor 21; the output time detection unit is used for acquiring the output time of the battery 22 and transmitting the output time to the processor 21.

The display 5 may be provided on the surface of the atomizing unit 1 or on the surface of the power supply unit 2, and may display the amount of atomization.

The preset algorithm in the processor 21 may be preset in advance or may be generated in real time. When the preset algorithm is preset in the processor 21, only one preset algorithm (for example, one of the first preset algorithm, the second preset algorithm, the third preset algorithm, and the fourth preset algorithm) may be preset, and which preset algorithm is selected to be used for calculating the atomization amount according to specific situations; or preset a plurality of preset algorithms (e.g., a first preset algorithm, a second preset algorithm, a third preset algorithm, a fourth preset algorithm).
