As shown in fig. 1, an aerosol-generating device is provided in an embodiment of the present application for providing an aerosol for inhalation by a user when inhaled by the user. The aerosol generating device comprises a heating element 110, a power source 120, a detection component 130 and a control component 140.
Wherein the heating element 110 is for heating the aerosol-forming substrate to produce an aerosol; the power supply 120 is electrically connected to the heating element 110, and is configured to output electrical energy to the heating element 110 so as to heat the heating element 110; the detection assembly 130 is electrically connected with the heating element 110 and the power supply 120; the control component 140 is electrically connected to the detecting component 130 and is used for obtaining the electrical parameter of the detecting component 130, and identifying the pumping action of the user according to the electrical parameter of the detecting component 130.
The detecting element 130 is electrically connected to the power source 120 and the heating element 110, and the resistance of the heating element 110 will also rise when the temperature rises, so that the electrical parameters of the detecting element 1301 electrically connected thereto will change. Because the heating temperature of the heating element 10 tends to be stable along with the increase of the heating time, and thus the resistance value of the heating element 110 tends to be stable, when the aerosol generating device is sucked by a user, the heat stored in the heating element 110 is reduced, and thus the resistance value of the heating element 110 is also reduced, so that according to the electrical parameter of the detection component 1301, whether the user performs suction can be judged, and the suction action can be accurately detected.
In one embodiment, the electrical parameter of the detecting component 130 may be a resistance value, a voltage across the two terminals, a power, a current, etc. In the embodiment of the present application, the voltage across the detecting component 130 is taken as an example for illustration.
In one embodiment, the control assembly 140 can control the heating temperature of the heating element 110 by controlling the power output by the power source 120 to the heating element 110 or the duration of the output to maintain the heating element 110 at a temperature that can stabilize the aerosol generation by atomization. It will be appreciated that the power supply 120 also has another connection path to the heating element 110 through which the power supply 120 provides power to the heating assembly when no detection is required.
The resistance of the heating element 110 changes with temperature, and as the temperature increases, the resistance of the heating element 110 increases. The control component 140 can limit the power-on time of the detection component 130, keep the resistance value of the detection component 130 unchanged, and can reflect the temperature change of the heating element 110 through the voltage change condition of the two ends of the detection component 130 based on the voltage division principle, and can determine that a user performs a suction action on the aerosol generating device when the temperature is suddenly changed.
It should be noted that, in fig. 1, the specific manner in which the detection assembly 130 is electrically connected to the heating element 110 and the power source 120 is: the detection assembly 130 is connected between the heating element 110 and the power source 120. At this time, the voltage at the end of the detecting component 130 connected to the power source 120, that is, the voltage representing the voltage level of the power source 120, the voltage at the end of the detecting component 130 connected to the heating element 110 depends on the resistance of the heating element 110 and the resistance of the detecting component 130. In other embodiments, the detecting component 130 may be electrically connected to the heating element 110 and the power source 120 by: the heating element 110 is connected between the detection assembly 130 and the power source 120. At this time, although the electrical connection is different, the voltage across the detecting component 130 is still dependent on the voltage of the power source 120, and on the resistance of the heating element 110 and the resistance of the detecting component 130. It will be appreciated that the heating element 110 and the detecting assembly 130 may be connected in other ways to form a partial pressure structure
In the aerosol generating device, the detection assembly 130 is electrically connected with the power supply 120 and the heating element 110, and the heating temperature of the heating element 110 tends to be stable along with the increase of the heating time, so that the temperature of the heating element 110 also tends to be stable; in addition, the addition of the sensor increases the cost of the aerosol generating device, the circuit design is more complex, the recognition of the pumping action can be realized only by arranging the detection component 130 between the heating element 110 and the power supply 120, the circuit design is simple, and the cost of the aerosol generating device is reduced.
As shown in fig. 2, in one embodiment, the detection assembly 130 is connected between the heating element 110 and the power source 120, and the detection assembly 130 includes: reference resistor RS and detection switch Q1. The first end of the detection switch Q1 is electrically connected with the power supply, the second end of the detection switch Q1 is electrically connected with the first end of the reference resistor RS, and the control end of the detection switch Q1 is electrically connected with the control component 140; a second end of the reference resistor RS is electrically connected to the heating element 110. The control component 140 is configured to obtain a first voltage V1 at a first end of the reference resistor RS and a second voltage V2 at a second end of the reference resistor RS, and identify a pumping action according to a change of the first voltage V1 and the second voltage V2; the control component 140 is further configured to control the detection switch Q1 to be turned on or off, so as to implement on or off of the detection mode.
In this embodiment, the electrical parameter of the detecting component 130 includes the voltage across the reference resistor RS. When the detection is needed, the control component 140 controls the detection switch Q1 to be turned on, at this time, the power supply 120 provides the reference resistor RS and the heating element 110 connected in series with each other with electric energy, the control component 140 obtains voltages at two ends of the reference resistor RS, namely, the first voltage V1 and the second voltage V2, and the first voltage V1 is the output voltage of the power supply 120, so that the first voltage V1 is maintained in a relatively stable voltage range, the second voltage V2 is affected by the resistance change of the heating element 110, and the second voltage V2 can be used for representing the resistance of the heating element 110 under the condition that the first voltage V1 is not abnormal, so that whether the pumping action occurs can be identified through the change of the first voltage V1 and the second voltage V2. In one embodiment, the control component 140 obtains multiple groups of first voltage V1 and second voltage V2 in the detection mode, screens out the maximum value and the minimum value of the first voltage V1 and the second voltage V2, and then respectively takes an average value, and finally adopts the average value of the first voltage V1 and the average value of the second voltage V2 to determine whether the pumping action occurs, thereby reducing detection errors and improving the accuracy of the identification.
In one embodiment, if the internal resistance of the detection switch Q1 is not greatly different from the resistance of the heating element 110, the detection switch Q1, the reference resistor RS and the heating element form a series voltage division, when the resistance of the heating element 110 changes, the first voltage V1 will also change suddenly, and at this time, the accuracy of the recognition can still be ensured when the first voltage V1 and the second voltage V1 are adopted to perform the suction recognition together.
When the detection mode is required to be turned off, the control component 140 controls the detection switch Q1 to be turned off, and cuts off the branch where the reference resistor RS is located, and the power supply 120 supplies power to the heating element 110 through the other branch.
In one embodiment, the detection switch Q1 may be an electronic switch such as a triode, a MOS transistor, or an IGBT.
In one embodiment, the electrical parameter of the detecting component 130 may be a resistance of the reference resistor RS, a power of the reference resistor RS, or a current flowing through the reference resistor RS.
In one embodiment, the control component 140 controls the detection switch Q1 to be turned on for a preset duration according to the preset period, and controls the detection switch Q1 to be turned off when the conduction time of the detection switch Q1 reaches the preset duration, and the control component 140 obtains the first voltage V1 and the second voltage V2 when the detection switch Q1 is turned on. For example, the preset period may be 10ms and the preset duration may be 250 μs.
In one embodiment, the control component 140 is configured to calculate the pumping state quantity according to the first voltage V1 and the second voltage V2, and determine that the pumping action occurs when the absolute value of the difference between the pumping state quantity at the current time and the pumping state quantity at the previous time is greater than a preset threshold.
The pumping state quantity is a physical quantity for characterizing the voltage change condition across the reference resistor RS. The preset threshold is a reference value reflecting the voltage change condition across the reference resistor RS when the pumping action does not occur and the heating element 110 is in a heating state. If there is a large error in determining the pumping action by directly passing through the first voltage V1 and the second voltage V2, and there is an abnormal change in the first voltage V1 and the second voltage V2 due to the electric quantity of the power supply 120 or other reasons, the pumping state quantity may be calculated according to the first voltage V1 and the second voltage V2, the absolute value of the difference between the current time and the pumping state quantity at the previous time may be calculated, and if the absolute value of the difference between the pumping state quantities is greater than the preset threshold, the pumping action at the current time is determined. For example, the pumping state quantity may be a difference between the first voltage V1 and the second voltage V2, or a rate of change of the difference between the first voltage V1 and the second voltage V2. It will be appreciated that the current time and the previous time refer to two consecutive detected times, and are not necessarily continuous in time. For example, the preset threshold may be 0.08.
In one embodiment, the pumping state quantity is equal to the product of the difference between the first voltage V1 and the second voltage V2. For example, assuming that the suction state quantity is K, k=v2 (V1-V2).
Table 1 shows a case where the MCU calculates the pumping state quantity K according to the collected first voltage V1, second voltage V2, and the absolute value Δk of the difference between pumping state quantities at adjacent two times varies with time in one pumping period in one embodiment.
TABLE 1
Specifically, when no pumping action occurs, Δk stabilizes below a preset reference value, for example 0.01. And after a pumping action, the resistance value of the heating element gradually rises to a steady state value along with heating, and in the process, Δk may be kept higher than a preset reference value, so after the pumping action is determined, the pumping action is determined to occur again after the Δk is identified to be lower than the preset reference value and then rises to exceed a preset threshold value again. For example, in table 1, when t=3, Δk exceeds the preset threshold value 0.08, it is determined that the pumping action is occurring, but when t=4, Δk is still greater than the preset threshold value 0.08, but when the resistance value of the heating element is continuously changing, it cannot be determined that the pumping action is occurring for the second time, and when it should be recognized again that Δk exceeds the preset threshold value 0.08 after time t=7, it is determined that the pumping action is occurring again.
In one embodiment, the control component 140 is further configured to update the suction count record upon determining that a suction action is occurring.
When the control unit 140 determines that the pumping operation has occurred, it adds 1 to the pumping count, and updates the pumping count record.
As shown in fig. 3, in one embodiment, the aerosol generating device further includes a power switch Q2, a first end of the power switch Q2 is connected to the heating element 110, a second end of the power switch Q2 is electrically connected to the power source 120, and a control end of the power switch Q2 is electrically connected to the control component 140; the control component 140 is used for sending a PWM signal to control the on-off of the power switch Q2 in the heating atomization mode; and the switch is also used for switching and controlling the power switch Q2 or the detection switch Q1 to be conducted so as to realize the switching of the heating atomization mode and the detection mode.
The control component 140 controls the on-off of the power switch Q2 by sending a PWM signal to realize the power control of the heating element 110, i.e. the temperature control of the heating element 110. In the state that the aerosol generating device is turned on or is triggered to be heated, the control component 140 outputs a PWM signal to the power switch Q2 to control on or off of the aerosol generating device, so as to adjust the power output to the heating element 110, and temperature control is realized, specifically, the temperature control can be controlled according to a preset temperature curve. When the detection mode needs to be switched to detect the pumping action, the power switch Q2 is controlled to be turned off, the detection switch Q1 is controlled to be turned on, and after the detection is finished, the control component 140 controls the detection switch Q1 to be turned off, and the power switch Q2 is controlled to work continuously through the occurrence of the PWM signal.
The embodiment can flexibly switch the detection mode and the heating atomization mode, and avoid the influence on the normal operation of the aerosol generating device due to detection.
