By adopting the scheme, the power gradient of the atomizer changes, and the gradient setting has the advantages that the output power can be regulated and controlled according to the air pressure, so that the taste of the tobacco tar is prevented from frequently changing.
As an improvement of the above, said q1The corresponding flow is not zero. By adopting the scheme, equivalently setting a minimum threshold value, when the flow is more than q1And then, the atomizer can be started, so that the problem of false start caused by light flow change can be avoided.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Referring to fig. 1 to 4, the present invention discloses a method of automatically adjusting power, a storage medium, and an aerosol generating apparatus.
User predefined control patterns: the device is started in a control mode and used for assisting suction of a user, and the method comprises the following steps of obtaining a flow-power function graph, wherein the flow-power function graph takes flow q as an abscissa and power w as an ordinate, and a step function w = f (q) is formed in the flow-power function graph, the flow q is flow entering a gas inlet 60 of the device, and the power w is actual working power of an atomizer; the device is started to operate: obtaining real-time traffic q1Then the corresponding power w is obtained based on the function map1W is to be1As the actual power at which the atomizer operates. Due to the flow rate q1Change in real time, so the actual power w of the atomizer1And also changes in real time, thus realizing auxiliary control. When the mapping functions of the flow q and the power w are different, the user can obtain different experiences; in other embodiments, the mapping function may be a continuous straight line or an arc.
As shown in fig. 2, in one embodiment, w = f (q) is a step function written as: w = f (q) is w = k1，[q1，q2）；k2，[q2，q3）；…；kn，[qn，qn+1) Wherein k is1、k2、…、knRespectively being different constants, q1、q2、…、qnAre target values of flow, q1To start the flow increase, w is the actual power at which the atomizer operates. By adopting the scheme, the power gradient of the atomizer changes, and the gradient setting has the advantages that the output power can be regulated and controlled according to the air pressure, so that the taste of the tobacco tar is prevented from frequently changing.
In other embodiments, w = f (q) is a proportional function, which may be written as w = k × q + c, where q is the flow rate, k is the slope, k >0, c is a constant, and w is the power, and as the flow rate into the device increases, the actual power of the nebulizer also increases. When c =0, the curve passes through the origin; several groups of direct proportional functions can be set on the storage medium and selected by the user, and after the selection of the user, k and c can be adjusted by the user to change the slope and the starting point of the curve.
In order to reduce false start, a start threshold value of the flow is set, and when the flow q is up1Executing the subsequent steps after the power is larger than the starting threshold value, and determining the corresponding power w1Then based on the power w1Operating the atomizer, q1The corresponding flow is not zero. Viewed as a function, said q1Corresponding flow not zero, q1The starting point on the abscissa is a non-zero point.
As shown in FIG. 2, q1q2q3q4May be an arithmetic or geometric series, respectively w1w2w3w4The incremental change of (a) may also be an arithmetic series or an geometric series. In the function, the numerical change corresponding to the flow q conforms to an arithmetic series, and the numerical change corresponding to the power w conforms to an arithmetic series; or the numerical change corresponding to the flow q in the function conforms to an arithmetic series, and the numerical change corresponding to the power w conforms to an geometric series; or the numerical change corresponding to the flow q in the function conforms to an geometric series, and the numerical change corresponding to the power w conforms to an arithmetic series; or the numerical change corresponding to the flow q in the function conforms to the geometric series, and the numerical change corresponding to the power w conforms to the geometric series.
But not limited to the above scheme, further, the flow rate q and the power w may also be set to other values, for example, the flow rate may be 0.4ml/s, 0.6ml/s, 1.0ml/s, 1.5ml/s in sequence, and the corresponding power may also be 20w, 23w, 30w, 40w, in the above scheme, the flow rate q and the power w may be freely combined and not affected by the geometric series of the equal difference series; meanwhile, the power w may also be set to 30w, 26w, 30w, 22w, like a state of fluctuation. Meanwhile, the hierarchy of the flow q division is not limited to four layers, and can be three layers, five layers or six layers. In the storage medium, after the user selects, the coefficients of the function can be adjusted by the user to achieve different effects.
Five smoke intensity modes are defined below according to the flow range span and the magnitude of the increase in power for each gradient: 1, if the flow range spans of all gradients are the same, the power increase amplitude is consistent, and a user can better regulate and control the power; 2, if the spans of all gradient flow ranges are the same, the increasing amplitude of the power is gradually reduced, so that the user can reduce the intake of the tobacco tar; 3, if the flow span of each gradient is the same, the increasing amplitude of the power is gradually increased, and the demand of an instant large tobacco tar user is met; 4, if the flow range span of each gradient is from large to small, the increasing amplitude of the power is gradually increased, so as to meet the demand of a user with larger tobacco tar in time; in the 5 th mode, if the flow range of each gradient spans from small to large, the increasing amplitude of the power is gradually reduced, so that the user can intake less tobacco tar. It will be appreciated that, for the same initial flow range span, as the user draws smoke with increasing suction and over time, the sequence of the amounts of smoke ingested in the 5 modes from large to small is: 4-3-1-2-5. The user can select one mode and start the mode switching function, and when the system is used for a certain time, the system is automatically switched to the next intensity mode, so that the smoking volume is gradually reduced, the user can adapt to the system more easily, and the effects of gradually reducing smoking and quitting smoking are achieved. For example, when the user selects the 3 rd mode and starts the mode switching function, the system will automatically switch to the 1 st mode after a certain time, and then gradually switch to the 2 nd to 5 th modes. But when the user selects the 3 rd mode and the mode switching function is not turned on, the user can continuously keep using the 3 rd mode.
Further, the mode switching function can not be cancelled by the user once the mode switching function is selected, and can only be cancelled by a reinstallation system mode, so that the user can be prompted to continuously reduce smoke and quit smoking.
In order to realize the effect of stopping smoking of the electronic cigarette, the actual power of the atomizer is gradually reduced according to the smoking time of the user, and the heavy user is gradually adaptive to less tobacco tar. For this purpose, in step S1, a control function w with respect to time-power is introducedt= f (t), wherein wtFor correcting power of the atomizer, wt>0, where w = f (q) -f (t), gradually decreasing the actual power of the nebulizer at the same flow rate as the user's pumping time increases. The control function may be selected to run straight or may be selected to start running when the lowest of the five smoke intensities is reached, with further reductions in smoke intake. And once the control function is selected, the user can not cancel the control function by himself, and can only cancel the control function by reinstalling the system, so that the user can be prompted to continuously reduce or stop smoking.
In one embodiment, the control function may decrease the power corresponding to the flow by a percentage at intervals, such as q1Corresponding power is w1W after a period of aspiration1Down to 0.8 w1After a further period of time, w1Down to 0.6 w1，q2Corresponding power is w2W after a period of aspiration2Also reduced to 0.8 × w2And so on. In another embodiment, the control function wtK = k × t, where k is the slope and t is the cumulative pumping time; the power is gradually reduced along with the increase of the pumping time, and the process of reducing the power is smoother. In another embodiment, the control function wtK + a sin (b) where k is the slope, t is the cumulative pumping time, and a and b are constants; by adopting the scheme, the power is in a descending trend on the whole, but the power of a certain section of node can still fluctuate up and down, and at the moment, the power can only decline a little and the difference is large, so that the user can adapt to the condition of less tobacco tar gradually. For example, when pumping for 1min, the power is 30 w; after pumping for 2min, the power is 28 w; after pumping for 3min, the power is 29 w; pumping at power of 22w for 4minAfter 5min, the power is 26 w; the power fluctuates appropriately during the overall descent.
On plateaus, the external atmospheric pressure becomes low, the oxygen content becomes low, and the air pressure difference generated by the same suction force of a user is smaller relative to the plain, so that the output power needs to be properly increased according to the air pressure difference value between the plateau and the plain and the difference value of the standard oxygen content, so that the same suction force is met, the same smoke effect is output, and the stability of the taste is kept. As shown in fig. 3, an atmospheric pressure-oxygen content function graph is obtained, the function graph takes atmospheric pressure p as an abscissa and oxygen content m as an ordinate, a continuous line m = f (p) is formed in the atmospheric pressure-oxygen content function graph, the actual power of the atomizer is then corrected based on the oxygen content corresponding to different altitudes, the actual power of the atomizer is increased when the oxygen content is lower than a reference value, and the actual power of the atomizer is decreased when the oxygen content is higher than the reference value, at this time, w = f (q)/f (p). The atmospheric pressure and the oxygen content are in inverse proportion, the higher the altitude is, the lower the oxygen content is, at the moment, m = k × p, wherein k is the slope, p is the atmospheric pressure, and m is the oxygen content; the atmospheric pressure and the altitude are in inverse proportion, the higher the altitude is, the lower the atmospheric pressure is, and then altitude parameters h, m = f (h), m = k are introduced1*k2H, wherein k1And k2All are constants, h is altitude, and m is oxygen content. The above constants and slopes can be filled in by referring to the existing data, and are not described herein again. Further, a control function, w = (f (q) — f (t))/f (p)), may be integrated to achieve better results.
Furthermore, the ambient atmospheric pressure of the device is judged according to the atmospheric pressure sensor so as to directly correspond to the oxygen content of the gas in unit volume, or the altitude of the device is determined according to the positioning server so as to indirectly determine the oxygen content of the gas in unit volume. The oxygen content of the gas in unit volume can be obtained by two schemes, the sensor can directly obtain the atmospheric pressure, the method is simple and efficient, the sensor can be used in a single machine mode, and the device does not need to be connected with the outside; the atmospheric pressure is obtained through the positioning service, the cloud can inquire and call different climate parameters of different areas, the judgment is accurate, and the device is small in size; if the positioning service is adopted, the device can be matched with the mobile equipment, a 'device retrieving function' is introduced (similar to retrieving of a mobile phone, the position of the device can be displayed on a related map app, and a user can be guided to find the device), and the device is prevented from being left in a remote position based on the position of the map display device.
