Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a logical block diagram of an aerosol-generating device according to an embodiment of the present invention, which includes a control module 11, an RLC circuit 12, and a heating element 13, wherein the heating element 13 may be embedded in an aerosol-generating substrate 14, and the heating element 13 is a heating element having a magnetic temperature characteristic, that is, a metal or an alloy having a specific curie temperature point (for example, 420 ℃), and a magnetic induction value of the heating element decreases with an increase in temperature and is almost linear, and the heating element 30 may be made of, for example, iron-nickel-chromium alloy. The RLC circuit 12 includes an inductance coil (having an internal resistance) L1, and at least a part of the inductance coil L1 is located in the magnetic field of the heat generating body 13. The control module 11 is configured to control the RLC circuit 12 to generate an alternating current on the inductor L1 to perform induction heating on the heating element 13, and determine the temperature of the heating element 13 by detecting specific parameters of the RLC circuit 12, where the specific parameters of the RLC circuit 12 include, for example: the voltage of the capacitor in the RLC circuit 12, the current of the inductor.
In this embodiment, when an alternating current is passed through the inductor L1, the heating element 13 generates heat inductively to heat the aerosol-generating substrate 14 for atomisation. When the temperature of the heating element 13 changes, the apparent resistance and inductance of the inductor L1 are affected because the heating element has a significant magnetic-temperature characteristic at a specific temperature (between 150 and 420 ℃). For the RLC circuit in operation, the inductance and apparent resistance change, which may cause the specific parameters of the RLC circuit 12 to change, for example, the voltage of the capacitor in the RLC circuit 12 and the current of the inductor coil, so that the temperature change of the heating element 13 can be determined according to the change of the specific parameters of the RLC circuit 12. In this detection method, since a temperature sensor is not required, the problem of limitation in the structural design of the aerosol generating apparatus is solved, and since the inductance coil L1 is not required to be electrically connected to the heating element 13, the problem of difficulty in cleaning due to the electrical connection is also solved.
Further, in an optional embodiment, the control module 11 is further configured to determine whether the pumping action has occurred according to the temperature of the heating body 13. In this embodiment, when a suction flow is passed through the aerosol-generating substrate, the heater experiences a significant temperature change, and hence detection of a suction event, and hence measurement of the number of suction openings, is achieved by a determined temperature change.
Further, in an optional embodiment, the control module 11 is further configured to detect a specific parameter of the RLC circuit 12 by way of timed wake-up in the standby state, and to implement insertion detection of the aerosol-generating substrate according to the detected specific parameter; and, in normal operating conditions, detecting a specific parameter of the RLC circuit 12 and enabling the detection of the extraction of the aerosol-generating substrate according to the detected specific parameter. In this embodiment, since the magnetic induction value of the heating element 30 is different between the case where the aerosol-generating substrate is inserted and the case where the aerosol-generating substrate is not inserted in the aerosol-generating device, the insertion/removal detection of the aerosol-generating substrate can be performed by detecting the specific parameter of the RLC circuit 12.
Further, in an optional embodiment, the control module 11 is configured to control the RLC circuit 12 to generate an alternating current on the inductor L1 for a first period of time to perform induction heating on the heating body 13; the temperature of the heat-generating body 13 is determined by detecting a specific parameter of the RLC circuit 12 during the second period.
Fig. 2 is a circuit diagram of a second embodiment of the aerosol-generating device of the present invention, which includes a control module, an RLC circuit, and a heat-generating body (not shown), wherein:
the heating element is a heating element with magnetic temperature characteristics, and the RLC circuit comprises an inductance coil L1, a first capacitor C1, a second capacitor C2, a first switch tube Q1 and a second switch tube Q2. At least a part of the inductor L1 is located in the magnetic field of the heating element 13, the first switch tube Q1 and the second switch tube Q2 are both MOS tubes, the source of the first switch tube Q1 is connected with the drain of the second switch tube Q2, the drain of the first switch tube Q1 is connected with the output end (BAT) of the battery, the source of the second switch tube Q2 is grounded, the first capacitor C1 and the second capacitor C2 are connected in series between the output end (BAT) of the battery and the ground, the first end of the inductor L1 is connected with the connection point of the first switch tube Q1 and the second switch tube Q2, and the second end of the inductor L1 is connected with the connection point of the first capacitor C1 and the second capacitor C2.
The control module includes voltage detection unit and first main control unit U1, and wherein, voltage detection unit is used for detecting the voltage of second electric capacity C2, and specifically includes: the circuit comprises a first diode D1, a third capacitor C3 and a resistor R1, wherein the anode of the first diode D1 is connected with the connection point of the second capacitor C2 and the first capacitor C1, and the third capacitor C3 and the resistor R1 are connected between the cathode of the first diode D1 and the ground. The input end of the first main control unit U1 is connected to the cathode of the first diode D1, the first output end of the first main control unit U1 is connected to the gate of the first switch tube Q1, the second output end of the first main control unit U1 is connected to the gate of the second switch tube Q2, and the first main control unit U1 is configured to determine the temperature of the heating element according to the voltage of the second capacitor C2.
In this embodiment, when the heating element needs to be heated, the first main control unit U1 controls the first switch tube Q1 and the second switch tube Q2 to be alternately turned on through the first output end and the second output end thereof, so that an alternating current is generated in the inductor L1, the heating element starts to generate heat by induction, and the magnitude of the heating power is related to the turn-on frequency and the control time of the two switch tubes. When the temperature of the heating element needs to be measured, the first main control unit U1 controls the first switch tube Q1 and the second switch tube Q2 to be alternately conducted through the first output end and the second output end, the RLC circuit starts to work, and the voltage on the second capacitor C2 is further influenced because the apparent resistance and the inductance of the inductance coil L1 are influenced by the temperature change of the heating element, so that the first control unit U1 detects the change of the peak voltage at the two ends of the second capacitor C2 through the first diode D1, and the change of the temperature of the heating element can be effectively fed back, as shown in fig. 3.
In this embodiment, it should be noted that the heating and temperature measurement of the heating element may be performed in the same time period or may be performed in two separate time periods. If the operation is performed in the same time interval, the two output ends of the first main control unit can output control signals with specific frequency in the time interval; if the operation is performed in different time periods, the two output ends of the first main control unit can output a control signal with a specific frequency in the first time period, and can output another control signal with a specific frequency in the second time period. In addition, the frequency of the control signal output in the same period may also be varied.
In one embodiment, to avoid the influence of the battery power, the first control unit, after detecting the peak voltage across the second capacitor C2, will also obtain the ratio of the peak voltage to the output voltage of the battery (i.e. the supply voltage of the RLC circuit), and feed back the change of the temperature of the heating element according to the change of the ratio, so as to avoid the occurrence of inaccurate temperature detection caused by low battery power.
In one embodiment, the first master control unit U1 further determines whether a pumping action has occurred based on the detected temperature change of the heater, and in particular, in conjunction with fig. 4, when a pumping airflow flows through the aerosol-generating substrate, the heater will experience a significant temperature change, and the first master control unit U1, after detecting the voltage across the second capacitor, detects whether a pumping action V has occurred by determining whether a significant jump in the ratio of the voltage to the output voltage of the battery has occurred, thereby performing a measurement of the number of pumping ports.
In a specific embodiment, the first main control unit U1 detects the voltage across the second capacitor C2 by waking up at a certain time in a standby state, and then compares the detected voltage with a first preset value, and implements the insertion detection of the aerosol-generating substrate according to the difference between the detected voltage and the first preset value; in normal operation, the voltage across the second capacitor C2 is detected, the detected voltage is then compared with a second preset value, and a pull-out detection of the aerosol-generating substrate is effected on the basis of the difference between the two. In addition, preferably, the frequency of the control signal output by the first main control unit U1 during plugging detection is lower than the resonant frequency of the RLC circuit.

In this embodiment, the heat generation control process of the second master control unit U2 is the same as that of the embodiment shown in fig. 2, and is not described herein again. When the temperature of the heating element needs to be measured, the second main control unit U2 controls the first switch tube Q1 and the second switch tube Q2 to be conducted alternately through the first output end and the second output end of the second main control unit, the RLC circuit starts to work, the apparent resistance and the inductance of the inductance coil L1 can be affected due to the temperature change of the heating element, the current on the inductance coil L1 is further affected, the current on the inductance coil L1 is detected by the current transformer IL1, the current is converted into voltage through the resistor R2, and then the voltage is sent to the input end of the second control unit U2 through the second diode D2, so that the temperature change of the heating element can be effectively fed back by the second control unit U2 according to the change of input signals of the input end of the second control unit.
