Please refer to FIG. 2 , which shows a method flowchart of a control method of an electronic cigarette provided by an embodiment of the present invention. This embodiment is illustrated by using the electronic cigarette control method shown in FIG. 1 as an example. As shown in Figure 2, the control method of the electronic cigarette may include:

Step 210, when the cigarette lighting signal is detected, determine the target liquid supply speed of the electronic cigarette according to the output parameters of the electronic cigarette.

The cigarette light signal involved in this application may be a pressing signal generated by pressing the cigarette light button on the electronic cigarette, or may be an air flow signal detected by an air flow sensor in the air passage connected to the mouthpiece in the electronic cigarette, which is not described in this application. Specific restrictions.

When the cigarette lighting signal is detected, the target liquid supply speed of the electronic cigarette is determined according to the first correspondence. Wherein, the first corresponding relationship is the change relationship between the liquid consumption speed of the electronic cigarette and the output parameter of the electronic cigarette. The specific implementation may be: acquiring the liquid consumption rate corresponding to the output parameter according to the first correspondence relationship, and determining the target liquid supply rate according to the liquid consumption rate.

First, the obtained liquid consumption rate is determined as the target liquid supply rate of the electronic cigarette.

The second is to calculate the sum of the obtained liquid consumption speed and the preset additional value to obtain the target liquid supply speed of the electronic cigarette to avoid dry burning. Among them, the added value is usually set by the system developer.

The third method is to multiply the obtained liquid consumption rate by a predetermined multiple to obtain the target liquid supply rate of the electronic cigarette. Optionally, the predetermined multiple is usually greater than or equal to 1 to avoid dry burning, and the specific value can be set by the system developer, for example, the predetermined multiple can be 1.02.

Step 220: Determine the target rotational speed of the motor according to the target liquid supply speed.

This step can be achieved in the following two ways:

The first one is to determine the motor speed corresponding to the target liquid supply speed in the second pair of relationships as the target speed of the motor, and determine the target speed of the motor according to the target moving speed. The second corresponding relationship is that the liquid supply speed of the electronic cigarette increases with The relationship between changes in motor speed.

The atomizer atomizes the smoke, that is, the electronic cigarette controls the atomizer to work according to the output parameter.

Please refer to FIG. 3 , which shows a method flowchart of a control method for an electronic cigarette provided by another embodiment of the present invention. This embodiment is illustrated by using the electronic cigarette control method in the electronic cigarette shown in FIG. 1 as an example. . As shown in Figure 3, the control method of the electronic cigarette may include:

Step 310, when the cigarette lighting signal is detected, determine the target liquid supply speed of the electronic cigarette according to the output parameters of the electronic cigarette.

For the implementation of this step, reference may be made to the implementation of step 210, and details are not repeated here.

Step 320, if the liquid supply speed detected by the metering assembly is lower than the target liquid supply speed, increase the rotation speed of the motor.

Wherein, the metering component can be arranged in the liquid supply pipe, and is used to detect the flow rate of the smoke liquid flowing out from the liquid storage member, that is, the liquid supply rate of the electronic cigarette.

Optionally, if the liquid supply speed detected by the metering assembly is higher than the target liquid supply speed, the rotation speed of the motor is reduced.

Please refer to FIG. 4 , which shows a method flowchart of a control method of an electronic cigarette provided by another embodiment of the present invention. This embodiment is illustrated by using the electronic cigarette control method in the electronic cigarette shown in FIG. 1 as an example. . As shown in Figure 4, the control method of the electronic cigarette may include:

In step 410, when the cigarette lighting signal is initially received, the pressing device is controlled to squeeze the liquid storage member, so that the liquid storage member provides the first amount of liquid smoke to the atomizing chamber.

This step can be achieved in the following ways:

The first method is to control the motor to rotate for a predetermined number of times, so that the extrusion device squeezes the first amount of smoke liquid in the liquid storage member into the atomizing cavity.

Among them, the predetermined number of turns is usually set by the system developer. For example, the developer can determine the number of turns that the motor rotates during the process of squeezing the first amount of e-liquid in the liquid storage device into the atomizing cavity by the extruding device. number.

Second, after starting to receive the cigarette lighting signal, according to the information detected by the metering component in the liquid supply pipe, determine the amount of smoke liquid provided to the atomization chamber after the start of the cigarette lighting; Before the amount of e-liquid reaches the first amount of e-liquid, control the rotation of the motor to drive the extrusion device to squeeze the liquid storage member; when the amount of e-liquid provided to the atomizing chamber reaches the first amount of e-liquid, stop controlling the rotation of the motor to drive the extrusion device to squeeze fluid storage.

Wherein, the information detected by the metering component in the liquid supply pipe may be the flow rate or the amount of the smoke liquid flowing into the atomization liquid from the liquid outlet member.

Step 420, before the cigarette lighting signal is not interrupted, determine the remaining amount of e-liquid in the atomization chamber according to the output parameters of the electronic cigarette and the first amount of e-liquid.

The implementation of this step can be: determining the consumption rate of the liquid smoke according to the output parameters of the electronic cigarette; calculating the product of the consumption rate and the cigarette lighting time to obtain the amount of liquid smoke consumed by the atomizing chamber after the last liquid supply; calculating the first smoke liquid The difference between the liquid volume and the amount of smoke liquid consumed by the atomizing chamber after the last liquid supply is obtained to obtain the remaining smoke liquid volume in the atomizing chamber.

Step 430, if the remaining amount of e-liquid in the atomizing chamber is lower than the second amount of e-liquid before the cigarette lighting signal is interrupted, control the pressing device to squeeze the liquid storage member, so that the liquid storage member continues to provide smoke to the atomizing chamber. liquid.

The second amount of e-liquid is set by the system developer, for example, the system developer can set the second amount of e-liquid to be a value close to or equal to 0.

During the execution of step 430, the pressing device is controlled to squeeze the liquid storage member, so that the liquid storage member provides a predetermined amount of e-liquid to the atomizing chamber. Wherein, the predetermined amount is usually set by the system developer, for example, the predetermined amount may be the above-mentioned first smoke liquid amount. Moreover, after the liquid storage element provides a predetermined amount of e-liquid to the atomizing chamber, the remaining amount of e-liquid in the atomizing chamber is determined according to the output parameters of the electronic cigarette and the predetermined amount, and step 430 is performed.

It should be noted that if the electronic cigarette receives the first cigarette lighting signal after it is turned on, steps 410 to 430 are executed; after that, the amount of e-liquid remaining in the atomization chamber is calculated as the next cigarette lighting at the end of each electronic cigarette lighting. The initial amount of e-liquid in the atomizer during smoking is determined, and the remaining amount of e-liquid in the atomization chamber is determined according to the output parameter and the initial amount of e-liquid in the next cigarette lighting process, and step 430 is executed.

To sum up, in the method provided by the embodiments of the present invention, when the cigarette lighting signal is initially received, the extruding device is controlled to squeeze the liquid storage member, so that the liquid storage member provides the first amount of e-liquid to the atomizing chamber. ; Before the cigarette lighting signal is not interrupted, determine the remaining amount of smoke liquid in the atomization chamber according to the output parameters of the electronic cigarette and the first amount of smoke liquid; At the second amount of e-liquid, the extruding device is controlled to squeeze the liquid storage member, so that the liquid storage member continues to provide e-liquid to the atomizing chamber, so as to control the liquid supply speed of the electronic cigarette to be greater than or equal to the liquid consumption speed during the cigarette lighting process. , to avoid dry burning.

In the actual implementation of any of the above embodiments, the liquid supply pipe is communicated with the atomizing chamber, and the atomizing chamber is communicated with the outside of the electronic cigarette. In one example, when the interruption of the cigarette lighting signal is detected, the extruding device is controlled to move away from the liquid storage member, so that the liquid storage member is restored to the shape before the extrusion force does not act on the liquid storage member, so as to control the extruding device to squeeze the liquid storage member next time. When pressed, the liquid reservoir quickly supplies liquid to the nebulizer. For example, when the interruption of the cigarette lighting signal is detected, the pressing device is controlled to move to the initial position, and when the cigarette lighting signal is detected again, the pressing device is controlled to move from the initial position to squeeze the liquid storage member.

In another example, when the interruption of the cigarette lighting signal is detected, the extruding device is controlled to stop moving, and the extruding device is controlled to continue extruding the liquid storage member next time, so that the liquid storage member quickly supplies liquid to the atomizer. Optionally, if the squeezing device moves to the extreme squeezing position, the squeezing device is controlled to move away from the liquid storage member, so that the liquid storage member returns to the shape before the squeezing force does not act on the liquid storage member, so as to detect the cigarette lighting again When the signal is received, the extruding device is controlled to extrude the liquid storage part.

Optionally, the electronic cigarette can also show the squeeze degree of the liquid storage part. The specific implementation may be: obtaining the first distance between the initial position and the current position of the pressing device; obtaining the second distance between the initial position and the extreme pressing position of the pressing device; calculating the difference between the first distance and the second distance The ratio gives the degree of squeezing of the reservoir.

The end of the liquid supply pipe inserted into the liquid storage part does not extend into the bottom of the liquid storage part (that is, the height from the end of the liquid supply pipe inserted into the liquid storage part to the bottom of the liquid storage part is greater than 0), and the cigarette lighting signal is interrupted When controlling the extrusion device away from the liquid storage part, if the liquid level in the liquid storage part is lower than the end of the liquid supply pipe inserted into the liquid storage part, the electronic cigarette controls the extrusion device to squeeze the liquid storage part according to the cigarette lighting signal. In the initial stage, the smokeless liquid enters the atomizer through the liquid supply pipe, which is prone to dry burning. To avoid this problem, if the liquid storage member is not squeezed by the pressing device, and the amount of e-liquid remaining in the liquid storage member is less than or equal to the third amount of e-liquid, a prompt message for prompting insufficient e-liquid is displayed; wherein, When the liquid storage member has the third amount of smoke liquid, the liquid supply pipe will supply liquid to the atomizing chamber only after the duration of pressing the liquid storage member by the extrusion device exceeds the preset duration.

The preset duration can be set by the system developer, for example, the system developer can set the preset duration to be 0.1 seconds, and the third amount of e-liquid can be determined by the system developer through multiple experiments.

In actual implementation, the relationship between the remaining amount of e-liquid in the liquid storage member and the third amount of e-liquid can be determined in the following two ways:

First, when the pressing device is not pressing the liquid storage member, obtain the liquid level detected by the liquid level detector in the liquid storage member; if the liquid level is lower than a predetermined height, display the prompt message, the predetermined height Insert the end of the fluid supply tube into the reservoir to the height of the bottom of the reservoir.

The second is to obtain the liquid level detected by the liquid level detector in the liquid storage member when the pressing device is not pressing the liquid storage member; and calculate the remaining smoke in the liquid storage member according to the liquid level detected by the liquid level detector. liquid volume.

For example, if the liquid storage member 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 remaining amount of smoke liquid in the liquid storage member.

The third is to obtain the remaining amount of e-liquid in the e-cigarette after the last injection; during the cigarette lighting process, the consumption of e-liquid is determined according to the output parameters and the lighting time, and the remaining e-cigarette is updated according to the consumption of e-cigarette. The amount of smoke.

Among them, the remaining amount of e-liquid in the electronic cigarette after the last injection of liquid can be the remaining amount of e-liquid entered by the user after the last injection of liquid is completed, or it can be the total capacity of the liquid storage part.

For example, after filling the liquid storage part with e-liquid, the user presses the filling confirmation button on the electronic cigarette to trigger the e-cigarette to update the remaining e-liquid in the electronic cigarette to the total capacity of the liquid storage part.

In an example of any of the above embodiments, if it is detected that the amount of e-liquid remaining in the electronic cigarette is lower than the second amount of e-liquid, it is considered that the e-liquid in the liquid storage member is exhausted, and a prompt for prompting insufficient e-liquid is displayed information. The second amount of e-liquid is set by the system developer, for example, the system developer may set the second amount of e-liquid to a value close to or equal to 0.

Optionally, the electronic cigarette may also provide a squeeze button, and when the electronic cigarette detects that the squeeze button is triggered, the electronic cigarette controls the squeezing device to squeeze the liquid storage member.
