Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element. If not conflicting, the embodiments of the present invention and the features of the embodiments may be combined with each other, which are all within the protection scope of the present invention.
It should be noted that, the power of the electronic cigarette and the heating power of the electronic cigarette referred to in the present application may be used interchangeably.
Example 1:
as shown in fig. 1, embodiment 1 of the present invention discloses a gesture control method for an electronic cigarette, which includes:
s1: acquiring acceleration values of the electronic cigarette in at least two axial directions among a first axial direction, a second axial direction and a third axial direction;
s2: identifying a control gesture of a user according to the acceleration value;
s3: controlling the working state of the electronic cigarette according to the control gesture;
wherein the first axial direction, the second axial direction and the third axial direction are perpendicular to each other.
When using the electronic cigarette of this embodiment, the electronic cigarette user holds the electronic cigarette with his hand, and then makes some specific gestures, such as shaking the electronic cigarette, driving the electronic cigarette to turn around, driving the electronic cigarette to move along a certain direction, and so on. After the electronic cigarette recognizes gestures of a user, the working state of the electronic cigarette is changed according to the gestures.
In a specific implementation, the first axial direction, the second axial direction and the third axial direction are perpendicular to each other to form a space rectangular coordinate system, and at least one acceleration sensor is respectively arranged in the three axial directions. As shown in fig. 2, a general electronic cigarette is composed of a cartridge 300 and a tobacco rod 200, and an acceleration sensor may be disposed on a PCB board of the tobacco rod 200 in a specific implementation.
Therefore, when a user holds the electronic cigarette and makes corresponding gesture actions, the acceleration sensors in all axial directions can detect the acceleration values in the three axial directions, so that the movement condition of the electronic cigarette in the three-dimensional space is perceived. At present, three axial acceleration sensors and three axial angular rate sensors are often adopted to recognize gestures, but the angular rate sensors have higher cost, and an algorithm for recognizing the gestures by utilizing the acceleration sensors and the angular rate sensors is complex, and particularly, the gesture resolving process takes longer time and occupies large system resources. In the control method of the embodiment, the angular rate sensor is omitted, the three acceleration sensors are arranged along the three mutually perpendicular axial directions, acceleration values of the three axial directions are collected in the process that the user operates the electronic cigarette to finish gesture actions, and the control gesture of the user is identified according to the change rule of the acceleration values. The control method only needs three axial acceleration values and does not need to carry out operation processing on the angular rates of the three axial directions, so that the data transmission and data processing quantity is small, the processing process is simpler, and the gestures of a user can be rapidly and accurately identified.
After accurately identifying the gesture of the user, the electronic cigarette can change the working state according to the gesture of the user, and the control mode does not need the user to find the corresponding key on the electronic cigarette, so that the control of the electronic cigarette is more convenient and flexible, the control mode is more random than the key control mode, and the interestingness of the electronic cigarette product in the use process is improved.
According to the embodiment, the control gesture of the user is identified according to the acceleration value of the electronic cigarette in the first axial direction and/or the second axial direction and/or the third axial direction and/or the positive and negative change rule of the acceleration value. The acceleration values or the changes of the three axial directions when the user drives the electronic cigarette to move through the gestures, the acceleration and the distance of the movement of the electronic cigarette can be calculated through the changes of the three axial acceleration values, and the direction of the movement of the electronic cigarette can be obtained through the magnitude relation and the positive and negative changes of the three axial acceleration, so that the gestures of the user can be recognized simply and rapidly.
As shown in fig. 3, a specific identification method may be:
the control gestures comprise gestures for driving the electronic cigarette to rotate for a preset number of turns, and the control gestures for identifying the user according to the acceleration value further comprise:
s21: when the absolute value of the acceleration value in one axial direction is larger than a first threshold value, taking the axial direction as a first reference direction, starting timing and monitoring the acceleration values in the two remaining axial directions;
the first threshold value can be obtained according to a use habit or an experimental test, and the first threshold value corresponds to an initial acceleration value when a user starts to drive the electronic cigarette to rotate.
S22: if the absolute value of the acceleration value of one of the two remaining axial directions is larger than a first threshold value, continuing to monitor, taking the axial direction as a second reference direction, and otherwise ending the detection;
only one detected acceleration value in one axial direction meets the requirement and cannot indicate that the electronic cigarette is doing the rotating motion, so that timing is started after the absolute value of the detected acceleration value in one axial direction exceeds a set threshold value, the other two axial directions are detected immediately, and whether the acceleration values in the other two axial directions change or not is judged. If the absolute values of the accelerations in the other two axial directions do not exceed the first threshold value within a prescribed time from the timing moment, the electronic cigarette is indicated to move only in one direction and does not rotate, and therefore detection is ended. I.e. it is only possible for the e-cigarette to turn if it is detected that the absolute value of the acceleration values in at least two axial directions exceeds a set threshold.
S23: if the positive and negative occurrence (Q-1) of the acceleration value in the first reference direction and the positive and negative occurrence (Q-1) of the acceleration value in the second direction are detected within the second preset time, judging that the control gesture is a control gesture rotating for Q circles, wherein q=Q/2, and Q is a positive even number greater than or equal to 2.
As shown in fig. 4 and 5, the axial direction in which the x direction is located is the first reference direction, the acceleration value detected in the first reference direction when the electronic cigarette moves in the x direction is positive, and the acceleration value detected in the first reference direction when the electronic cigarette moves in the direction opposite to the x direction is negative. The axial direction of the y direction is a second reference direction, the acceleration value detected in the second reference direction when the electronic cigarette moves in the y direction is positive, and the acceleration value detected in the second reference direction when the electronic cigarette moves in the direction opposite to the y direction is negative.
As shown in fig. 4, in the first reference direction, the change rule of the acceleration changes from negative to positive, which changes positive and negative 1 time, and as shown in fig. 5, the change rule of the acceleration in the second reference direction changes from positive to negative to positive, which changes positive and negative 2 times, q=2. Q=2/2=1, i.e. the recognized gesture is a control gesture of one turn.
For example, in the first reference direction, the change rule of the acceleration changes from negative to positive, from positive to negative, from negative to positive, and from positive to negative 3 times, and in the second reference direction, the change rule of the acceleration changes from positive to negative, from negative to positive, and from positive to negative, and from negative to positive, and from positive to negative, is changed 4 times, and q=4. Q=4/2=2, i.e. the recognized gesture is a control gesture rotating two turns.
As the method only needs to detect the acceleration and the positive and negative change conditions, the acquired parameters are few, the gesture recognition algorithm is simple, and the occupation of system resources is relatively less.
As shown in fig. 6, the control gesture includes a gesture for shaking the electronic cigarette, and identifying the control gesture of the user according to the acceleration value further includes:
s201: taking the axial direction as a first reference direction when the absolute value of the acceleration value in the axial direction is detected to be larger than a first threshold value, and starting timing at the same time;
and when the absolute value of the acceleration value is detected to be larger than the first threshold value as the starting time of the shaking gesture, timing is performed. And monitoring the positive and negative conditions of the acceleration value of the first reference direction.
S202: and judging the control gesture as a shaking gesture when the frequency of detecting positive and negative changes of the acceleration value of the first reference direction exceeds a second threshold value.
The frequency of detecting the positive and negative changes of the acceleration value of the first reference direction meets a preset value, and the fact that the user shakes the electronic cigarette is indicated. The frequency of the positive and negative changes may be set according to the number of times the acceleration value is positively and negatively changed within the set period of time. If no change in the positive or negative of the acceleration value is detected within a predetermined time, the monitoring is stopped until the next time the absolute value of the acceleration value in one axial direction is detected to be larger than the first threshold value, and the monitoring is restarted.
The gesture of shaking the electronic cigarette is identified by adopting the frequency of positive and negative changes of the acceleration value, the acquired data are less, the algorithm is simple, and the gesture of shaking can be identified rapidly and accurately.
Example 2
In this embodiment, the control gesture includes a gesture for driving the electronic cigarette to rotate a preset number of turns or a gesture for shaking the electronic cigarette, and in a working state of controlling the electronic cigarette according to the control gesture, the heating power of the electronic cigarette is controlled according to the number of turns of the electronic cigarette rotating or the frequency of shaking the electronic cigarette.
The more turns the e-cigarette is rotated, the more power the e-cigarette is heated, and the higher the frequency of shaking, for example, the more power the e-cigarette is heated. The gesture of rotating or shaking is adopted to control the heating power of the electronic cigarette, so that the electronic cigarette is convenient and quick, and the user brings a certain interest.
Various lights can be arranged on the electronic cigarette and distributed at different positions of the electronic cigarette, and the lights can emit the same or different colors. And controlling the lighting state of the lamplight of the electronic cigarette according to the direction and the acceleration of the control gesture in the working state of the control electronic cigarette according to the control gesture. For example, gestures in different directions may illuminate different colors of lights. The faster the acceleration of the gesture, the higher the brightness of the light. The faster the acceleration of the gesture, the greater the number of lights illuminated, etc. The gesture mode is adopted to control the lighting state of the electronic cigarette, so that the lighting state is more convenient and quicker than key control, and the interest brought to a user is higher.
In the working state of the electronic cigarette controlled according to the control gesture, the on-off state of the electronic cigarette can be controlled according to the direction and the acceleration of the control gesture. For example, when the control gesture is a movement in a certain direction, the electronic cigarette is in an on state, and when the control gesture is a movement in the opposite direction, the electronic cigarette is in an off state. For example, when the acceleration reaches a certain set value, the electronic cigarette is switched between an on state and an off state.
As shown in fig. 7, further, before S1, acquiring the acceleration value of the electronic cigarette in the first axial direction and/or the second axial direction and/or the third axial direction further includes:
s01: acquiring set gesture control parameters;
s02: and establishing a corresponding relation between the control gesture and the working state of the electronic cigarette according to the gesture control parameters.
And S3, controlling the working state of the electronic cigarette according to the corresponding relation in the working state of the electronic cigarette according to the control gesture.
The gesture control parameters are what gestures are adopted to control which working state of the electronic cigarette. The control method of the embodiment allows the user to select what gesture is used to control the working state of the electronic cigarette, for example, the user can select whether to control the heating power of the electronic cigarette by using the number of turns of the turn or the frequency of shaking the electronic cigarette, and the user can also select whether to control the switch of the electronic cigarette by using the direction of the gesture or the acceleration of the gesture.
Example 3
In the foregoing manner, the control gesture includes a gesture for driving the electronic cigarette to rotate a preset number of turns or a gesture for shaking the electronic cigarette, and in the working state of controlling the electronic cigarette according to the control gesture, the heating power of the electronic cigarette is controlled according to the number of turns of the electronic cigarette or the frequency of shaking the electronic cigarette. Specifically, when the number of turns of the electronic cigarette or the frequency of shaking the electronic cigarette reaches a third threshold, the electronic cigarette is controlled to enter a preset working mode, and the power of the electronic cigarette can be adjusted according to the suction habit of a user in the preset mode. The preset working modes comprise:
acquiring preset parameters; the preset parameters comprise preset power P of the electronic cigarette s First weight W 1 Second weight W 2 ；
Obtaining a first average airflow velocity of the last n times of sucking the electronic cigaretteWherein n is a positive integer;
obtaining the last m times of sucking the electronic cigaretteTwo average airflow velocityWherein m is a positive integer, and m>n；
According to the formulaCalculating a theoretical airflow velocity V;
according to the formulaCalculating theoretical power P;
and adjusting the power of the electronic cigarette according to the theoretical power P.
Specifically, the preset power of the electronic cigarette refers to the power at the time of the next suction. If the user cannot automatically adjust the power of the electronic cigarette, the preset power is the fixed power of the electronic cigarette in design; if the user can manually adjust the power of the electronic cigarette, the preset power is the power set by the user when the next suction is performed.
First weight W 1 Second weight W 2 Is a real number. In a preferred embodiment of the invention, the first weight W 1 Second weight W 2 The values of the (C) are all larger than 0. In a preferred embodiment of the invention, the first weight W 1 And a second weight W 2 The sum is 1. For example, a first weight W 1 Equal to 0.2, a second weight W 2 Equal to 0.8.
When the user uses the electronic cigarette, the heating components such as the heating wire or the atomizing core of the electronic cigarette start to work by sucking the electronic cigarette, and when the sucking is finished, the heating components such as the heating wire or the atomizing core stop to work. Therefore, unless specifically described, the suction of the electronic cigarette 1 time referred to herein refers to a process from the start to the stop of the operation of the heating member.
The last n puffs of the e-cigarette means that the e-cigarette is smoked n times closest to the time interval between the next puffs of the e-cigarette. Similarly, the last m puffs of the e-cigarette means that the e-cigarette is smoked m times closest to the time interval in which the e-cigarette is smoked next. For example, the electronic cigarette is smoked 5 times in total, and is respectively marked as a first time of smoking, a second time of smoking, a third time of smoking, a fourth time of smoking and a fifth time of smoking according to time sequence, then the last 2 times of smoking refers to the fourth time of smoking and the fifth time of smoking, and the last 4 times of smoking refers to the second time of smoking, the third time of smoking, the fourth time of smoking and the fifth time of smoking. The last 1 puff of the e-cigarette is referred to as the fifth puff.
When a user sucks the electronic cigarette, the user sucks smoke through the flow of gas in the airflow channel of the electronic cigarette. Thus, the flow rate of the gas flow referred to herein refers to the flow rate of the gas in the flow path of the e-cigarette. The gas flow rate may be detected by a gas sensor, such as a gas flow rate sensor, or a gas flow meter in combination with a timer may be used to obtain the gas flow rate. Of course, it will be understood by those skilled in the art that the average airflow rate referred to herein may be an arithmetic average, i.e., the sum of the airflow rates from each puff divided by the number of puffs. The average airflow rate may also be a weighted average, i.e., the airflow rates for each puff may be weighted differently.
First average airflow rate for last n puffs of the e-cigaretteFor characterizing short-term habits of the user. n is a positive integer, and in a preferred embodiment of the invention n is 15. Of course, the specific value of n is not particularly limited in the present invention.
Second average airflow velocity for last m puffs of the e-cigaretteFor characterizing the long-term habits of the user. m is a positive integer, and the value needs to be greater than n, in a preferred embodiment of the present invention, m is the total number of times of smoking of the electronic cigarette.
Thus, when the first average airflow velocityAnd a second average airflow rate->When they are not equal, it is indicated that the short-term habit and the long-term habit of the user are not the same, and thus it is determined that the user wants to change the amount of smoke sucked by changing the force of suction (i.e., airflow rate).
At this time, the formula is passedAnd estimating the airflow velocity of the electronic cigarette sucked by the user next time to obtain a theoretical airflow velocity V. Obviously, when the first average airflow velocity +.>Greater than the second average airflow rate->(meaning that the user increases the suction force), the theoretical airflow rate V will be greater than the second average airflow rate +.>Thus according to the formulaThe calculated theoretical power P is larger than the preset power, so that the power of the electronic cigarette is improved, and the electronic cigarette is ensured to generate more smoke for a user to inhale. When the first average airflow velocity +>Less than the second average airflow rate->(meaning that the user reduces the suction force) the theoretical airflow rate V will be smaller than the second average airflow rate +.>Thus according to the formulaThe calculated theoretical power P is smaller than the preset power, so that the power of the electronic cigarette is reduced, the problem that a user cannot timely absorb a large amount of smoke due to small suction force is avoided, and the consumption of tobacco tar and power is reduced. In summary, the embodiment of the invention realizes automatic adjustment of the power of the electronic cigarette according to the suction habit of the user, and greatly improves the user experience.
Further, a first average airflow velocityThe method can be obtained by adopting the following technical scheme, and comprises the following steps.

Obtaining a third average airflow velocity of the electronic cigarette sucked for n-1 times except the electronic cigarette sucked for 1 time recently in the electronic cigarette sucked for n times recently
According to the formulaCalculating said first average airflow rate +.>
Wherein the preset parameters further comprise a third weight W 3 And a fourth weight W 4 . Third weight W 3 And a fourth weight W 4 Are real numbers. In a preferred embodiment of the invention, the third weight W 3 And a fourth weight W 4 The values of the (C) are all larger than 0. In a preferred embodiment of the invention, the third weight W 3 And a fourth weightW 4 The sum is 1. For example, a third weight W 3 Equal to 0.1, fourth weight W 4 Equal to 0.9.
As described above, if the electronic cigarette is smoked 5 times, the first, second, third, fourth and fifth puffs are respectively marked according to the time sequence. When the value of n is 4, the electronic cigarettes sucked for n-1 times except the electronic cigarette sucked for 1 time recently in the electronic cigarette are referred to as second suction, third suction and fourth suction.
Third average airflow velocityThe detection method is the same as that of the previous embodiment, and the detection can be performed by a gas sensor, which is not repeated here.
Therefore, the embodiment of the invention acquires the first airflow velocity V of the last 1 times of sucking the electronic cigarette 1 And a third average airflow velocityAnd respectively obtaining the weights corresponding to them to determine a first average airflow velocity +.>Obviously, the first average airflow rate +.>To a great extent by a third weight W 3 And a fourth weight W 4 The theoretical airflow velocity V of the electronic cigarette sucked by the user next time can be correspondingly changed according to the determined adjustment weight. If the theoretical airflow velocity V is expected to be mainly determined by the first airflow velocity V of the last 1 suction of the electronic cigarette 1 The third weight W is determined 3 Setting larger makes the power adjustment more sensitive; if the expected theoretical airflow velocity V is determined primarily by the average airflow velocity of the last n puffs of the e-cigarette, a fourth weight W may be applied 4 The setting is larger so that the power adjustment is determined by the average of n puffs, i.e. the power adjustment is smoother, reducing false adjustments.
Further, a second average airflow rateThe method can adopt the following technical scheme for acquisition, and comprises the following steps.
Obtaining fourth average airflow velocity of m-n times of sucking the electronic cigarette except the last n times of sucking the electronic cigarette in the last m times of sucking the electronic cigarette
According to the formulaCalculating the second average airflow velocity +.>
Wherein the preset parameters further comprise a fifth weight W 5 And a sixth weight W 6 . Fifth weight W 5 And a sixth weight W 6 Are real numbers. In a preferred embodiment of the invention, the fifth weight W 5 And a sixth weight W 6 The values of the (C) are all larger than 0. In a preferred embodiment of the invention, the fifth weight W 5 And a sixth weight W 6 The sum is 1. For example, a fifth weight W 5 Equal to 0.05, a sixth weight W 6 Equal to 0.95.
As described above, if the electronic cigarette is smoked 5 times, the first, second, third, fourth and fifth puffs are respectively marked according to the time sequence. When the value of n is 2 and the value of m is 4, the m-n times of sucking the electronic cigarette except the n times of sucking the electronic cigarette in the last m times of sucking the electronic cigarette refers to the second sucking and the third sucking.
Wherein,first average airflow velocityThe manner of determining (c) has been described in detail in the foregoing embodiments, and is not repeated here. Fourth average airflow velocity->The detection may be performed by a gas sensor.
The embodiment of the invention acquires the first average airflow velocity of the electronic cigarette sucked for the last n timesAnd a fourth average airflow rate->And respectively obtaining the weights corresponding to them to determine the second average airflow velocity +.>Obviously, the second average airflow rate +.>To a great extent by a fifth weight W 5 And a sixth weight W 6 The theoretical airflow velocity V of the electronic cigarette sucked by the user next time can be correspondingly changed according to the determined adjustment weight. If the expected theoretical airflow velocity V is determined primarily by the first average airflow velocity (i.e., short term habit) of the last n puffs of the e-cigarette, a fifth weight W may be applied 5 Setting larger makes the power adjustment more sensitive; if the expected theoretical airflow velocity V is determined primarily by the average airflow velocity (i.e., long term habit) of the last m puffs of the e-cigarette, a sixth weight W may be applied 6 The power adjustment is set larger, so that the power adjustment is determined by the average value of m times of suction, namely, the power adjustment is more stable, and the error adjustment is reduced.
Furthermore, the power curve obtained by fitting can be used for adjusting the power of the electronic cigarette, and the method specifically comprises the following steps.

fitting a plurality of theoretical powers P to obtain a power curve;
and adjusting the power of the electronic cigarette according to the power curve.
As previously mentioned, the airflow rate may be detected by a gas sensor. Thus, the first airflow velocity V can be measured by setting a plurality of sampling points (e.g., 10) per second 1 And (5) detecting. Obviously, the greater the number of sampling points, the greater the corresponding sampling data, thereby making the power adjustment more accurate.
In the foregoing embodiment, it is illustrated that the first average airflow rate may be calculated by the formula And (5) performing calculation. Therefore, if the last 1 times of sucking the electronic cigarette is 2 seconds, 5 sampling points are set every second, 10 first average airflow velocity +.>The 10 first average gas flow rates are recorded as +.>
