[0056] like Figure 1As shown, the method for calculating the remaining number of puffs provided by the present invention is applied to an electronic atomizer, comprising:

[0057] S110 , obtaining a power range of the heater and an airflow velocity of the atomization channel of the electronic atomizer during a puff cycle.

[0058] In this embodiment, the electronic atomizer in this solution includes a mouthpiece, an atomizing assembly and an electronic control assembly; the atomizing assembly includes an atomizing channel, a heater and an atomizing matrix, the heater is arranged in the atomizing channel, the heater is in contact with the atomizing matrix and can heat the atomizing matrix to make it gaseous during operation, and then discharge it from the suction channel of the mouthpiece after passing through the atomizing channel to the user for inhalation; the electronic control assembly includes a display screen, an airflow sensor, a battery and a circuit board, and the circuit board includes a circuit board chip; the heater, the display screen and the airflow sensor are all electrically connected to the circuit board, and thus also electrically connected to the battery and the circuit board chip. In step S110, the airflow velocity of the atomizing channel can be obtained by the airflow sensor, and the power section of the heater in the inhalation cycle of the electronic atomizer can be monitored by the circuit board chip.

[0059] It should be noted that the circuit board chip can instantly obtain the airflow velocity v in the atomization channel monitored by the airflow sensor. If the airflow velocity v is greater than the airflow velocity threshold Va for starting the heater, the battery is controlled to supply power to the heater to start heating the atomization matrix, and start timing the duration t of the current puff cycle; the airflow velocity vt is continuously monitored. If the airflow velocity vt is detected to be less than va, the power supply to the heater is stopped, and the timing of t is stopped. The above is the process of a puff cycle. The circuit board chip of the electronic atomizer can obtain the heating power section of the heater in this puff cycle; common airflow sensors can directly measure the pressure difference change during puffing, and the airflow velocity can be calculated based on the pressure difference change. This is a conventional method, so the specific airflow velocity monitoring details will not be discussed here.

[0060] S120 , determining the air flow rate of the inhalation cycle according to the air flow velocity, and querying the diffusion coefficient of the corresponding atomized substrate from a pre-stored correspondence table according to the power segment.

[0061] In this embodiment, when the air flow rate of the puff cycle is calculated based on the air flow velocity, it is obtained by the following calculation formula: Q=VSt, where S is the cross-sectional area of ​​the atomization channel, t is the duration of the puff process, and V is the average air flow velocity during the puff cycle.

[0062] The heating power section of the heater can be set and changed by the user through the button on the electronic atomization device, or it can be automatically adjusted by the circuit board chip of the electronic atomizer based on the temperature of the heater. The power section in this solution is divided corresponding to the vaporization temperature range of the atomization matrix. The setting of the heating power section of the heater is to ensure the constant heating temperature. For example, after the user selects the power section, the circuit board chip can monitor the heater temperature and adjust the output in real time to ensure that the temperature is relatively stable.

[0063] It is understandable that the heater has different efficiencies in heating and vaporizing the atomized matrix in different power ranges. For example, 6W-9W is the first heating power range, and 10W-13W is the second heating power range. The second power range can heat and vaporize the atomized matrix more quickly than the first power range. Here, the efficiency of heating, vaporizing, and diffusing the atomized matrix is ​​represented by the diffusion coefficient, and a corresponding relationship table between the heating power range of the heater and the diffusion coefficient of the atomized matrix is ​​pre-set and stored in a storage unit of the circuit board chip. Therefore, the corresponding diffusion coefficient of the atomized matrix can be queried from the pre-stored corresponding table.

[0064] S130 , calculating the consumption of the atomized substrate in the inhalation cycle according to the diffusion coefficient and the air flow rate, and confirming the remaining amount of the atomized substrate of the electronic atomizer according to the atomized substrate consumption.

[0065] In this embodiment, after obtaining the diffusion coefficient of the atomizing matrix, the consumption of the atomizing matrix in this puffing cycle is calculated in combination with the air flow rate of the atomizing channel in this puffing cycle. When confirming the consumption of the atomizing matrix in the puffing cycle based on the diffusion coefficient and the air flow rate, it is obtained by the following calculation formula: M=QN, wherein Q is the air flow rate in the puffing cycle, and N is the diffusion coefficient of the atomizing matrix corresponding to the preset power section.

[0066] It should be noted that, since the atomized matrix is ​​heated and vaporized by the heater, it will only be considered consumed after being discharged after being inhaled by the user; if the atomized matrix is ​​not discharged by the airflow after being heated and vaporized, it will be retained on the surface of the heater and then re-condensed into a liquid atomized matrix, and it will not be consumed. Therefore, after the heater is started, the atomization channel can only ensure the smooth consumption of the atomized matrix if there is sufficient airflow. In this solution, the heating temperature of the heater in a heating power section is relatively constant, and there will be no problem of the heater temperature dropping due to a large airflow, which will affect the diffusion coefficient of the atomized matrix. Thus, the greater the amount of air discharged, the more atomized matrix is ​​consumed. Moreover, the atomization channel of the existing electronic atomizer usually has a small cross-section, and the airflow velocity generated by the user's inhalation will not be too large. Therefore, the amount of air passing through per unit time will not be too much, which can meet the discharge of the atomized matrix after heating and vaporization, and there will be no situation where the consumption of the atomized matrix does not change after the airflow changes. In addition, different atomized matrices, as well as the contact and transfer methods between the atomized matrix and the heater, will affect the diffusion coefficient of the atomized matrix. These factors are not considered in this scheme.

[0067] S140 , calculating an average atomized substrate consumption in a single puff cycle based on the atomized substrate consumption in the most recent K puff cycles, where K is greater than 0.

[0068] In this embodiment, K=4. By obtaining the atomized substrate consumption in the most recent four puff cycles as a reference, the average atomized substrate consumption in a single puff cycle is calculated, which can make the value of the average atomized substrate consumption more representative, that is, it can make subsequent calculations more accurate.

[0069] S150 , calculating the remaining number of puffs based on the remaining amount of the atomized substrate and the average consumption of the atomized substrate, and displaying the remaining number of puffs.

[0070] In this embodiment, the remaining number of puffs can be calculated based on the calculated average value of the atomized matrix consumption and the remaining atomized matrix of the electronic atomizer, and the remaining number of puffs can be displayed on the display screen so that the user can directly and clearly understand the remaining number of puffs of the electronic atomizer.

[0071] like Figure 2 As shown, in step S110, obtaining the power section of the heater of the electronic atomizer in the puff cycle includes:

[0072] S111, obtaining the real-time heating power of the heater of the electronic atomizer during the puffing cycle;

[0073] S112, determining the power range of the real-time heating power;

[0074] S113 : Query the corresponding power segment from a preset power segment table according to the power range.

[0075] In this embodiment, the circuit board chip can record the real-time heating power of the heater during the puff cycle of the electronic atomizer, identify the maximum and minimum values ​​of the real-time heating power, and determine the power range of the real-time heating power in this puff cycle. According to the power range, the corresponding power segment can be queried from the preset power segment table.

[0076] like Figure 3 As shown, in step S130, the step of calculating the remaining amount of the atomized substrate of the electronic atomizer according to the atomized substrate consumption includes:

[0077] S131, storing the atomized substrate consumption as the latest atomized substrate consumption in a preset storage unit, and replacing the atomized substrate consumption of the earliest puffing cycle stored in the storage unit as the latest atomized substrate consumption;

[0078] S132. Subtract the current remaining amount of atomizing substrate stored in the storage unit from the latest consumption of atomizing substrate to obtain the remaining amount of atomizing substrate of the electronic atomizer, and store it in the storage unit as the new current remaining amount of atomizing substrate.

[0079] In this embodiment, the atomization matrix consumption within the puff cycle is calculated based on the diffusion coefficient and the airflow rate, that is, according to the calculation formula: M=QN, the consumption can be calculated, Q is the airflow rate of the puff cycle, and N is the diffusion coefficient of the atomization matrix corresponding to the preset power section. The consumption of the atomization matrix is ​​stored in a storage unit, and the atomization matrix consumption of the puff cycle most recently stored in the storage unit is replaced as the latest atomization matrix consumption, that is, for each puff cycle, the storage unit will update the most recent atomization matrix consumption, and the remaining atomization matrix remaining in the electronic atomizer is obtained based on the atomization matrix consumption. When the consumption of a new puff cycle is stored in the storage unit, the consumption of the new puff cycle will be used as the latest atomization matrix consumption, and then the remaining atomization matrix of the current electronic atomizer can be obtained by subtracting the consumption of the new puff cycle from the remaining atomization matrix after the last puff of the electronic atomizer.

[0080] like Figure 4As shown, in step S150, the steps of calculating the remaining number of puffs according to the remaining amount of the atomized substrate and the average consumption of the atomized substrate, and displaying the remaining number of puffs include:

[0081] S151, taking the average value of the atomized substrate consumption as the atomized substrate consumption value of one puff cycle of the electronic atomizer;

[0082] S152: Obtain the remaining number of puffs according to the ratio of the remaining amount of the atomized substrate to the atomized substrate consumption value, and display the remaining number of puffs.

[0083] In this embodiment, the average value of the atomization matrix consumption is used as the atomization matrix consumption value of each puff cycle of the electronic atomizer, so that the data calculated later can be closer to reality. The remaining number of puffs is obtained according to the remaining amount of the atomization matrix / the atomization matrix consumption value. The result obtained in this way is closer to the actual situation, and the displayed number of puffs is more in line with the actual situation of the user and more accurate. The remaining number of puffs is displayed on the display screen, which makes it easy for the user to intuitively understand the remaining number of puffs of the electronic atomizer.

[0084] Furthermore, the method for calculating the remaining number of puffs further includes:

[0085] If the storage unit does not store any atomized substrate consumption of the vertical puffing cycle, the atomized substrate consumption is directly used as the atomized substrate consumption average value;

[0086] If the atomized substrate consumption of the historical puffing cycles stored in the storage unit is less than K times, the atomized substrate consumption average value is calculated according to the actually recorded atomized substrate consumption.

[0087] In this embodiment, the atomized substrate consumption is less than K times, K=4, which means that the electronic atomizer is just beginning to be inhaled. At this time, the atomized substrate consumption can be directly used as the atomized substrate consumption average value, that is, the atomized substrate consumption average value is calculated according to the actually recorded atomized substrate consumption.
