detailed description

In order to make the purpose of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

Example 1

As shown in FIG. 1, an embodiment of the present application provides an electronic cigarette control method, which includes the following steps:

S1. Obtain the work start signal of the electronic cigarette;

The sensor or button switch can be used to detect whether there is a work start signal for the electronic cigarette. If the sensor detects or the button switch is triggered, it means that there is a work start signal. In other words, the work start signal can be generated by a sensor or a manual control button; such as manual generation: by setting a button on the surface of the electronic cigarette, when the button is pressed, it is equivalent to sending out a start smoking The signal of, that is, the work start signal is generated; for example, it is automatically generated: the user inhales the mouthpiece on the electronic cigarette, so that the air pressure in the electronic cigarette changes, and then the work start signal is generated. The controller connected to the sensor or the button switch obtains the work start signal. Wherein, the controller may be a single-chip microcomputer or the like. It is understandable that the method for obtaining the work start signal of the electronic cigarette can also be obtained by the acousto-optic element, etc. Therefore, the method is not specifically limited herein. In this embodiment, the airflow sensor of the electronic cigarette is cyclically scanned by the controller of the electronic cigarette to obtain the working start signal of the electronic cigarette.

S2, get the time interval between the start of work this time and the last stop of work;

The time interval between starting work this time and stopping work last time refers to the time interval between the current puff and the previous puff, that is, the time difference between the two puffs. The time record of each puff can be recorded in Locally, it can also be recorded in the cloud. The method for obtaining the time interval between the start of work this time and the last time the work was stopped may be: acquiring according to the time interval between the airflow sensor of the e-cigarette this time starting to send the sensing signal and the last time stopping the sensing signal, or Obtained according to the time interval between the electric heating element of this electronic cigarette starting to work and the last time it stopped working. For example, when a user smokes an electronic cigarette, the airflow sensor of the electronic cigarette detects the work start signal generated by the user due to smoking, and the controller of the electronic cigarette obtains the work start signal through the airflow sensor, thereby controlling the electronic cigarette The electric heating element works to form an aerosol by atomizing smoke oil. When each puff of smoke is finished, the electric heating element stops working, and the controller records the time when the electric heating element stops working. When the user smokes again, the controller again controls the electric heating element of the electronic cigarette to work, and records the time when the electric heating element starts to work.

That is to say, in two adjacent puffs, the time when the electric heating element stops working and the time when the electric heating element starts working is the time interval. It can be understood that, in one embodiment, when the work start signal of the electronic cigarette is obtained by the button switch being triggered, in two adjacent puffs, the stop time of the work start signal and the start time of the work start signal The time difference between is the time interval. Therefore, the method of obtaining the time interval between the current start of work and the last stop of work is not specifically limited here.

S3. Compare the time interval with a preset time interval, and when the time interval is greater than the first preset time interval, control the electronic cigarette to work at the first power, and if the duration of the first power is greater than The electronic cigarette is turned off for the first preset duration; when the time interval is greater than the second preset time interval but less than or equal to the first preset time interval, the electronic cigarette is controlled to work at the second power, And if the duration of the second power is greater than a second preset duration, the electronic cigarette is turned off; wherein the first power is greater than the second power.

The first preset time interval is greater than the second preset time interval, and the first preset time interval and the second preset time interval can be set as needed, for example, the first preset time The interval can be 40 seconds, 50 seconds, 60 seconds, etc., and the second preset time interval can be 10 seconds, 15 seconds, or 20 seconds. Of course, the second preset time interval can also be 0 seconds. This is not specifically limited. In an embodiment of the present application, the first preset time interval is not less than 60 seconds, or/and the second preset time interval is not less than 15 seconds, which is more in line with the user's usage habits, thereby providing suitable The amount of smoke smoked by the user is good for the experience.

The first power and the second power can be set according to the type of electronic cigarette and the type of e-liquid, which are not specifically limited here. At the beginning of work, by collecting the voltage of the power supply battery of the electronic cigarette, and then calculating the duty cycle of the pulse width modulation signal according to the voltage of the power supply battery and the preset first power or second power, and then according to the calculated The pulse width modulation signal controls the conduction of the semiconductor switch used to control the operation of the electric heating element, and further controls the heating of the electric heating element. It can be understood that the first power and the second power may be variable power or constant power. In an embodiment of the present application, the first power and the second power are constant power, which is easier to control.

Optionally, the first preset duration is less than the second preset duration, and the first preset duration and the second preset duration can be set as needed, for example, it can be 6 Seconds, 7 seconds, 8 seconds, 9 seconds, 10 seconds, etc., in this embodiment, the first preset duration is 6 seconds, and the second preset duration is 9 seconds. If the duration of the first power is greater than the first preset duration, the electronic cigarette is turned off, that is, the semiconductor switch for controlling the operation of the electric heating element is controlled to be non-conducting. Similarly, if the duration of the second power is greater than the second preset duration, the electronic cigarette is turned off. That is, the duration of the electronic cigarette during high-power work is controlled to be less than the duration of low-power work, so as to better ensure the amount of smoke and avoid burning the mouth due to long working hours.

Example 2

Referring to FIG. 2, the steps of this embodiment are similar to those of Embodiment 1, and the difference is that: step S3 of the electronic cigarette control method of this embodiment further includes: when the time interval is less than or equal to a second preset At the time interval, the electronic cigarette is controlled to work at the third power, and if the duration of the third power is greater than the third preset duration, the electronic cigarette is turned off; wherein, the second power is greater than the first power Three power.

The third power and the third preset duration can be set as required, as long as the second power is greater than the third power. Optionally, the second preset duration is less than the third preset duration. This embodiment atomizes the e-liquid by setting multiple different powers corresponding to multiple different time intervals during the smoking process. The greater the power, the shorter the duration, the smaller the power, and the longer the duration, thus improving better This improves the stability of the amount of smoke and avoids the problem of hot mouth when the temperature is too high.

Example 3

Referring to FIG. 3, the steps in this embodiment are similar to those in Embodiment 1, and the difference lies in that: before obtaining the time interval between the current start of work and the last stop of work, the present embodiment further includes the following steps:

S11. Obtain e-liquid margin information;

Before the user uses the e-cigarette, the e-cigarette has been filled with e-cigarette and the total amount of e-cigarette is written in the memory of the e-cigarette. During the work of the e-cigarette, the consumption of e-cigarette is positively correlated with the power. For one puff, the controller of the e-cigarette calculates the consumption of e-liquid per puff according to the power and time of each puff, and after each puff, the total amount of e-liquid before smoking is subtracted from each puff. The e-liquid consumption of the cigarette is calculated, and the current e-liquid margin of the electronic cigarette is calculated, and the current e-liquid margin is written into the memory of the electronic cigarette. Therefore, after acquiring the work start signal, and before acquiring the time interval between the current start of work and the last stop of work, the current smoke is obtained by reading the remaining amount of e-liquid in the memory. Oil remaining information. It is understandable that the amount of e-liquid remaining can be determined in different ways according to different types of e-liquid and electronic cigarettes. Therefore, the method for obtaining the e-liquid margin is not specifically limited here.

S12. Compare the e-liquid margin with a preset e-liquid margin to determine whether the e-liquid margin is less than a first preset margin;

The difference between the e-liquid margin read from the memory and the e-liquid margin preset in the memory is calculated to obtain the amount of the e-liquid margin.

S13: When the remaining amount of e-liquid is less than the first preset remaining amount, control the electronic cigarette to maintain a closed state.

That is to say, when the amount of e-liquid remaining is very small and it is likely to cause dry burning immediately after smoking, even if the work start signal is obtained, the electronic cigarette is controlled to remain in the closed state to avoid dry burning, thereby protecting the user's health.

In an embodiment of the present application, when the e-liquid margin is greater than or equal to the first preset margin and less than the second preset margin, the electronic cigarette is controlled to work at a fourth power, wherein the fourth power The power is less than the first power. That is to say, when the e-liquid margin is greater than or equal to the first preset margin but less than the second preset margin, so that you cannot smoke arbitrarily, work at low power to prevent the electric heating element of the electronic cigarette from burning dry, and Can make full use of the remaining smoke oil to avoid waste. In a preferred embodiment of the present application, the fourth power is smaller than the second power to better avoid dry burning.

Example 4

Referring to FIG. 4, the steps of this embodiment are similar to those of Embodiment 1, and the difference is that: before obtaining the time interval between the current start of work and the last stop of work, this embodiment further includes:

S14. Obtain environmental temperature information;

Due to the difference in ambient temperature, the surface temperature of the electronic cigarette will be different, so that the heat transferred to the user's mouth when smoking is different. The temperature sensor connected to the controller can be set on the electronic cigarette, and when the work start signal is obtained, the temperature signal on the temperature sensor can be read by the controller to obtain the temperature of the environment around the electronic cigarette , That is, the temperature of the user's environment.

S15. Adjust the first preset time interval and the second preset time interval according to the ambient temperature.

The controller adjusts the first preset time interval and the second preset time interval according to the ambient temperature, so that a better user experience can be obtained in areas with different temperatures. Optionally, the first preset time interval and the second preset time interval are proportional to the ambient temperature, and the first power and the second power are inversely proportional to the ambient temperature. That is, when the ambient temperature is higher, the first preset time interval and the second preset time interval are longer, and the first power and the second power are smaller, so that it can better avoid burning the mouth . When the ambient temperature is lower, the first preset time interval and the second preset time interval are shorter, and the first power and second power are greater, so the amount of smoke can be better guaranteed. In a cold environment, it can provide enough heat to the user.
