Referring to fig. 2, a method flowchart of a method for controlling an electronic cigarette according to an embodiment of the present invention is shown, and the embodiment illustrates that the method for controlling an electronic cigarette is used in the electronic cigarette shown in fig. 1. As shown in fig. 2, the control method of the electronic cigarette may include:
and step 210, when the cigarette lighting signal is detected, determining the target liquid supply speed of the electronic cigarette according to the output parameters of the electronic cigarette.
The cigarette lighting signal referred to in this application may be a pressing signal generated by pressing a cigarette lighting key on the electronic cigarette, or may be an airflow signal detected by an airflow sensor in an air passage communicating with the mouthpiece in the electronic cigarette, which is not specifically limited in this application.
And when the cigarette lighting signal is detected, determining the target liquid supply speed of the electronic cigarette according to the first corresponding relation.

And step 220, determining the target rotating speed of the motor according to the target liquid supply speed.
This step can be achieved in two ways:
firstly, the motor rotating speed corresponding to the target liquid supply speed in the second pair of relations is determined as the target rotating speed of the motor, the target rotating speed of the motor is determined according to the target moving speed, and the second corresponding relation is the change relation of the liquid supply speed of the electronic cigarette along with the change of the rotating speed of the motor.

Secondly, determining the target moving speed of the pressing block according to the target liquid supply speed, and determining the target rotating speed of the motor according to the target moving speed.
The specific implementation can be as follows: calculating the quotient of the target liquid supply speed and the amount of the smoke liquid extruded into the atomizing cavity by the pressing block moving to the liquid storage part for a unit distance to obtain a target moving speed; and determining the rotating speed of the motor when the extrusion device moves according to the target moving speed to obtain the target rotating speed of the motor.

Optionally, in another embodiment, steps 210 and 220 may be directly replaced by: and acquiring a target rotating speed corresponding to the output parameter. The specific implementation can be as follows: and acquiring the corresponding motor rotating speed of the output parameter in the third corresponding relation.
The third corresponding relation can be stored in the electronic cigarette in a functional relation, a table form or a functional curve form, the liquid consumption speed of the electronic cigarette when the electronic cigarette is output by any value of the output parameter is the same as or similar to the preset liquid supply speed, and the preset liquid supply speed is the liquid supply speed when the motor rotates according to the motor rotating speed corresponding to any value in the third corresponding relation. The system developer can determine the corresponding relation between the output parameter and the motor rotating speed according to the first corresponding relation and the second corresponding relation to obtain a third corresponding relation.
In summary, in the method provided by the embodiment of the present invention, when the cigarette lighting signal is detected, the target liquid supply speed of the electronic cigarette is determined according to the output parameter; determining a target rotating speed of the motor according to the target liquid supply speed; and controlling the motor to rotate according to the target rotating speed so as to supply liquid according to the output parameters in real time in the cigarette lighting process, thereby avoiding dry burning.
In addition, in the process that the extrusion device is controlled to extrude the liquid storage part by executing the steps shown in fig. 2 or fig. 3 so that the tobacco juice in the liquid storage part enters the atomization cavity, the electronic cigarette also controls the atomizer to atomize the smoke according to the output parameters, namely, the electronic cigarette controls the atomizer to work according to the output parameters.
Referring to fig. 3, a method flowchart of a method for controlling an electronic cigarette according to another embodiment of the present invention is shown, and the present embodiment illustrates that the method for controlling an electronic cigarette is applied to the electronic cigarette shown in fig. 1. As shown in fig. 3, the control method of the electronic cigarette may include:
and 310, when the cigarette lighting signal is detected, determining the target liquid supply speed of the electronic cigarette according to the output parameters of the electronic cigarette.
The implementation of this step can refer to the implementation of step 210, and is not described in detail here.
If the liquid supply rate detected by the metering assembly is less than the target liquid supply rate, the rotational speed of the motor is increased, step 320.
Wherein, this measurement subassembly can set up in the feed tube for detect the velocity of flow of flowing out the tobacco juice from stock solution spare, also the liquid supply speed of electron cigarette.
Optionally, if the liquid supply rate detected by the metering assembly is higher than the target liquid supply rate, the rotational speed of the motor is decreased.
In practical implementation, the magnitude relation between the liquid supply speed detected by the metering component and the target liquid supply speed is periodically detected in the process of receiving the cigarette lighting signal. If the liquid supply speed detected by the metering component is lower than the target liquid supply speed, the rotating speed of the motor is increased by a basic step length; if the measured supply rate is greater than the target supply rate, the motor speed is reduced by a base step. Wherein the basic step size is typically set by the system developer.
In summary, in the method provided by the embodiment of the present invention, when the cigarette lighting signal is detected, the target liquid supply speed of the electronic cigarette is determined according to the output parameter of the electronic cigarette; and if the liquid supply speed detected by the metering component is lower than the target liquid supply speed, increasing the rotating speed of the motor to increase the liquid supply speed of the electronic cigarette so as to control the liquid supply speed of the electronic cigarette to be greater than or equal to the liquid consumption speed in the cigarette lighting process and avoid dry burning.
Referring to fig. 4, a flowchart of a method for controlling an electronic cigarette according to still another embodiment of the present invention is shown, and the present embodiment illustrates the method for controlling an electronic cigarette used in the electronic cigarette shown in fig. 1. As shown in fig. 4, the control method of the electronic cigarette may include:
and step 410, when a cigarette lighting signal is received, controlling the extruding device to extrude the liquid storage part, so that the liquid storage part provides the first amount of tobacco juice to the atomizing cavity.
This step can be achieved in several ways:
firstly, the motor is controlled to rotate for a preset number of turns, so that the extruding device extrudes the tobacco juice of the first tobacco juice amount in the liquid storage part to the atomizing cavity.
The predetermined number of turns is usually set by a system developer, for example, the developer can determine the number of turns of the motor in the process of extruding the tobacco juice of the first tobacco juice amount in the liquid storage part to the atomizing cavity by the extruding device through multiple experiments.
Secondly, after a cigarette lighting signal is received, the amount of the smoke liquid provided to the atomizing cavity after the cigarette lighting is started is determined according to the information detected by the metering component in the liquid supply pipe; before the tobacco juice amount provided to the atomization cavity reaches a first tobacco juice amount, controlling the motor to rotate to drive the extrusion device to extrude the liquid storage part; when the tobacco juice volume that provides the atomizing chamber reaches first tobacco juice volume, stop control motor and rotate and drive extrusion device extrusion stock solution spare.
The information detected by the metering component in the liquid supply pipe can be the flow speed or the smoke liquid amount of smoke liquid flowing into the atomization device from the liquid storage part.
And step 420, determining the amount of the residual smoke liquid in the atomization cavity according to the output parameter of the electronic cigarette and the first smoke liquid amount before the cigarette lighting signal is not interrupted.
The step can be realized; determining the consumption speed of the tobacco juice according to the output parameters of the electronic cigarette; calculating the product of the consumption speed and the cigarette lighting time length to obtain the amount of the cigarette liquid consumed by the atomizing cavity after the last liquid supply; and calculating the difference between the first tobacco liquid amount and the tobacco liquid amount consumed by the atomizing cavity after the last liquid supply to obtain the residual tobacco liquid amount in the atomizing cavity.
And 430, if the residual smoke liquid amount in the atomizing cavity is lower than the second smoke liquid amount before the cigarette lighting signal is not interrupted, controlling the extruding device to extrude the liquid storage part so that the liquid storage part continues to provide the smoke liquid to the atomizing cavity.
The second amount of smoke is set by a system developer, for example, the system developer may set the second amount of smoke to a value close to or equal to 0.
In step 430, the squeezing device is controlled to squeeze the reservoir to provide a predetermined amount of liquid to the aerosolizing chamber. The predetermined amount is usually set by a system developer, and may be the first smoke amount. And after the liquid storage part provides the predetermined amount of the smoke liquid to the atomization chamber, determining the amount of the smoke liquid left in the atomization chamber according to the output parameter of the electronic cigarette and the predetermined amount, and executing step 430.
It should be noted that, if the electronic cigarette receives the first cigarette lighting signal after starting up, step 410 to step 430 are executed; and then, calculating the residual smoke liquid amount in the atomization cavity as the initial smoke liquid amount in the atomizer when the electronic cigarette is lit for the next time after the electronic cigarette is lit for each time, determining the residual smoke liquid amount in the atomization cavity according to the output parameters and the initial smoke liquid amount in the next lighting process, and executing step 430.
In summary, in the method provided in the embodiment of the present invention, when the cigarette lighting signal is received, the extruding device is controlled to extrude the liquid storage component, so that the liquid storage component provides the first amount of liquid smoke to the atomizing chamber; before the cigarette lighting signal is not interrupted, determining the residual cigarette liquid amount in the atomization cavity according to the output parameter of the electronic cigarette and the first cigarette liquid amount; if the residual smoke liquid amount in the atomization cavity is lower than the second smoke liquid amount before the cigarette lighting signal is not interrupted, the extrusion device is controlled to extrude the liquid storage part, so that the liquid storage part continues to provide the smoke liquid to the atomization cavity, the liquid supply speed of the electronic cigarette is controlled to be higher than or equal to the liquid consumption speed in the cigarette lighting process, and the dry burning is avoided.
In actually realizing any of the above embodiments, the liquid supply tube is communicated with the atomizing chamber, and the atomizing chamber is communicated with the outside of the electronic cigarette. In one example, the squeezing device is controlled to be away from the liquid storage part when the cigarette lighting signal interruption is detected, so that the liquid storage part is restored to the shape before the squeezing force acts on the liquid storage part, and the liquid storage part can be rapidly supplied to the atomizer when the squeezing device is controlled to squeeze next time. For example, the pressing device is controlled to move to the initial position when the interruption of the lighting signal is detected, and the pressing device is controlled to start moving from the initial position to press the liquid storage member when the lighting signal is detected again.
In another example, when the cigarette lighting signal is detected to be interrupted, the extrusion device is controlled to stop moving, and the next time the extrusion device is controlled to continue extruding the liquid storage part, so that the liquid storage part can quickly supply liquid to the atomizer. Optionally, if the squeezing device moves to the extreme squeezing position, the squeezing device is controlled to be away from the liquid storage part, so that the liquid storage part is restored to the shape before the squeezing force does not act on the liquid storage part, and the squeezing device is controlled to squeeze the liquid storage part when the cigarette lighting signal is detected again.
Optionally, the electronic cigarette may also exhibit a degree of squeezing of the reservoir. The specific implementation can be as follows: acquiring a first distance between an initial position and a current position of an extrusion device; acquiring a second distance between the initial position and the limit extrusion position of the extrusion device; and calculating the ratio of the first distance to the second distance to obtain the extrusion degree of the liquid storage part.
One end that the feed tube inserted in the stock solution spare does not stretch into the bottommost of stock solution spare (that is, the one end that the feed tube inserted in the stock solution spare to the height of stock solution spare bottom is greater than 0), and under the circumstances that the control extrusion device kept away from the stock solution spare when lighting a cigarette signal and cutting off, if the liquid level was less than the one end that the feed tube inserted in the stock solution spare, the electron cigarette passed through the feed tube entering atomizer according to lighting a cigarette signal control extrusion device's initial stage smokeless liquid that the stock solution spare, dry combustion easily takes place. In order to avoid the problem, if the liquid storage part is not extruded by the extruding device and the amount of the residual tobacco juice in the liquid storage part is less than or equal to the third tobacco juice amount, a prompt message for prompting the shortage of the tobacco juice is displayed; wherein, under the circumstances that the stock solution spare possesses the third tobacco juice volume, the liquid feed pipe just supplies liquid to the atomizer chamber after the duration of extrusion device extrusion stock solution spare exceeded length of time in advance to predetermine.
The preset time duration can be set by a system developer, for example, the preset time duration can be set to 0.1 second by the system developer, and the third flue gas amount can be determined by the system developer through multiple experiments.
In actual practice, the relationship between the amount of smoke remaining in the reservoir and the third amount of smoke may be determined in two ways:
firstly, when the liquid storage part is not extruded by the extruding device, the liquid level detected by a liquid level detector in the liquid storage part is obtained; the prompt message is displayed if the liquid level is below a predetermined height, the predetermined height being the height from the end of the liquid supply tube inserted into the liquid storage member to the bottom of the liquid storage member.
Secondly, when the liquid storage part is not extruded by the extruding device, the liquid level detected by a liquid level detector in the liquid storage part is obtained; and calculating the residual smoke liquid amount in the liquid storage part according to the liquid level detected by the liquid level detector.
For example, if the liquid storage part is a cylinder, the product of the cross-sectional area of the bottom surface of the cylinder and the liquid level detected by the liquid level detector is calculated to obtain the amount of smoke remaining in the liquid storage part.
Thirdly, obtaining the residual tobacco juice amount in the electronic cigarette after the last liquid injection is finished; and in the cigarette lighting process, determining the cigarette liquid consumption according to the output parameters and the cigarette lighting time, and updating the residual cigarette liquid amount in the electronic cigarette according to the cigarette liquid consumption.
The residual tobacco juice amount in the electronic cigarette after the last liquid injection can be the residual tobacco juice amount input by a user after the last liquid injection is finished, and can also be the total capacity of the liquid storage part.
For example, after the liquid storage piece is filled with the tobacco juice, the user presses a full-filling confirmation key on the electronic cigarette to trigger the electronic cigarette to update the remaining tobacco juice amount in the electronic cigarette to the total capacity of the liquid storage piece.
In an example of any of the above embodiments, if it is detected that the amount of smoke liquid remaining in the electronic cigarette is lower than the second amount of smoke liquid, it is considered that the internal smoke liquid in the liquid storage member is exhausted, and a prompt message for prompting insufficient smoke liquid is displayed. The second amount of smoke is set by a system developer, for example, the system developer may set the second amount of smoke to a value close to or equal to 0.
Optionally, the electronic cigarette may further provide a squeezing key, and when the electronic cigarette detects that the squeezing key is triggered, the squeezing device is controlled to squeeze the liquid storage part.
Optionally, the electronic cigarette may further provide a deceleration liquid supply key and an acceleration liquid supply key, and when it is detected that the deceleration liquid supply key is pressed, the speed at which the liquid storage part is extruded by the extruding device is reduced; when detecting that the acceleration liquid supply key is pressed, improving the speed of extruding the liquid storage part by the extruding device.
The method can be realized in the following ways:
firstly, when an accelerated liquid supply key is detected to be triggered, the liquid consumption speed corresponding to each value of an output parameter in a first corresponding relation is synchronously increased; and when the deceleration liquid supply key is triggered, reducing the liquid consumption speed corresponding to each value of the output parameters in the first corresponding relation.
Secondly, when the liquid supply acceleration key is detected to be triggered, the rotating speed of the motor corresponding to each value of the liquid supply speed in the second corresponding relation is synchronously increased; and when the speed reduction liquid supply key is triggered, synchronously reducing the rotating speed of the motor corresponding to each value of the liquid supply speed in the second corresponding relation.
Thirdly, when the accelerated liquid supply key is detected to be triggered, the rotating speed of the motor corresponding to each value of the output parameters in the third corresponding relation is synchronously increased; and when the deceleration liquid supply key is triggered, synchronously reducing the rotating speed of the motor corresponding to each value of the output parameter in the third corresponding relation.
