the battery cell 10 is a rechargeable direct current battery cell and can output direct current;
the circuit 20, which is electrically connected to the rechargeable battery cell 10 by a suitable electrical connection, is used to convert the direct current output from the battery cell 10 into an alternating current with a suitable frequency, and then supply the alternating current to the inductance coil L.
The inductor L may comprise a helically wound cylindrical inductor coil, as shown in fig. 1, depending on the arrangement in use of the product.

According to the preferred embodiment shown in fig. 1, the inductor coil L is a helical coil extending in the axial direction of the chamber and arranged around the chamber.
In a more preferred implementation, the frequency of the alternating current supplied by the circuit 20 to the inductor L is between 80KHz and 400 KHz; more specifically, the frequency may be in the range of approximately 200KHz to 300 KHz.

In the preferred embodiment shown in fig. 1 and 2, the susceptor 30 is in the form of a sheet extending in the axial direction of the chamber, and may have a length of about 12 millimeters, a width of about 4 millimeters, and a thickness of about 50 micrometers, and may be made of grade 430 stainless steel (SS 430). As an alternative embodiment, the susceptor 30 may have a length of about 12 millimeters, a width of about 5 millimeters, and a thickness of about 50 micrometers, and may be made of grade 430 stainless steel (SS 430). Correspondingly, the susceptor 30 may also be in a pin or needle-like configuration.
Or in yet another preferred embodiment, the susceptor 30a may also be configured in a cylindrical shape, as shown in fig. 3; the inner space is arranged, in use, to receive smokable material a and to generate an aerosol for inhalation by means of heating the outer periphery of the smokable material a. These susceptors may also be made from grade 420 stainless steel (SS420), as well as iron-nickel containing alloy materials such as permalloy.
With further reference to the preferred embodiment shown in fig. 2, the susceptor 30 is provided at both ends with electrically conductive pins, in particular a first pin 31 and a second pin 32, respectively, for connecting the susceptor 30 to the circuit 20. In operation, susceptor 30 is fabricated to have a positive temperature resistivity based on the use of a material having excellent magnetic permeability as described above for susceptor 30, and the temperature of susceptor 30 can be determined by calculating its effective resistance upon application of a sensed electrical signal to susceptor 30 after it is coupled to electrical circuit 20 in use.
In particular, to enable detection of the effective resistance of the above susceptor 30, the configuration of the circuit 20 may be seen in one embodiment in fig. 4-5; the method comprises the following steps:
an MCU controller 21 as a controller for controlling the operation of each functional module;
the first power supply module 22 may be implemented by using a commonly used DC/AC inverter or LC oscillator, and the like, and is configured to convert a direct current of the battery cell 10 into an alternating current and supply the alternating current to the inductance coil L, so that the inductance coil L generates an alternating magnetic field;

the detection module 24 is used for detecting the resistance value of the receptor 30 under the direct current detection voltage and determining the temperature of the receptor 30 through the resistance value.
Specifically, as shown in fig. 5, an embodiment of the second power supply module 23 and the detection module 24 may be implemented, where the second power supply module 23 forms a voltage dividing circuit by a standard voltage dividing resistor R1 connected in series with the susceptor 30, and is respectively connected to the voltage output end of the battery cell 10 and the ground, so as to provide a suitable detection voltage for the susceptor 30;
the detection module 24 further collects the voltage of the sensor 30 through a sampling terminal in + of an operational amplifier U, and obtains the voltage of the sensor 30 through comparison calculation with the reference voltage of the reference terminal in-. The calculation result is fed back to the MCU controller 21, and the effective resistance of the susceptor 30 can be calculated by the MCU controller 21 according to the proportional relationship of the standard voltage dividing resistor R1. The actual temperature of the susceptor 30 may further be determined based on the temperature coefficient of resistance.
In a variant implementation, the mode of the operational amplifier U reference terminal in-provided by the output terminal of the battery cell 20 in fig. 4 may be changed to a mode of direct grounding, and then the grounded voltage is used as a reference voltage for comparison calculation.
In a further preferred embodiment, in order to increase the resistance value detectable by the susceptor 30, as shown in fig. 6, the blade-like susceptor 30b is provided with at least one notch 33b extending in the longitudinal direction; during the detection process, when the susceptor 30b is detected through the first and second leads 31b and 32b, the current passing through the susceptor 30b is in the form of an arrow shown in fig. 6. By providing the notches 33b in a row, the cross-sectional area of the current of the susceptor 30b is reduced, and the path distance of the current is increased, so that the resistance detected by the susceptor 30 can be increased. Meanwhile, as can be seen from fig. 6, in order to facilitate smooth insertion of the upper end portion of the blade-shaped susceptor 30b into the smokable material a for heating without affecting the upper end portion, the first pins 31b and the second pins 32b are connected to the susceptor 30b through the lower end portion of the susceptor 30b shown in fig. 5.
Or in the preferred embodiment shown in fig. 7, the tubular susceptor 30c is likewise provided with at least one notch 33c extending in the axial direction; furthermore, the notch 33c is used to guide the current path during the detection process, so that the susceptor 30c can have a higher detectable resistance value when measuring the temperature through the first pin 31c and the second pin 32c, thereby improving the accuracy of the temperature detection result. And as can be seen from fig. 7, for the resistance value of the susceptor 30c in a tubular shape for easy lift detection, the first leg 31c and the second leg 32c are connected to the susceptor 30c at positions at both ends of the susceptor 30c in the length direction, respectively.
It can of course be seen further from fig. 7 that when there are a plurality of indentations 33c, the arrangement of these indentations 33c is different, in particular a first indentation 331c extending lengthwise from the upper end of the susceptor 30c and a second indentation 332c extending lengthwise from the upper end of the susceptor 30c, so as to have different opening orientations; and when there are a plurality of the notches 33c, the first notches 331c and the second notches 332c are alternately arranged in the circumferential direction of the susceptor 30c, so that the current passing through the susceptor 30c during the sensing has a winding current path as shown by arrows in fig. 7, thereby increasing the magnitude of the sensed resistance value.
Or in a further variant, as shown in fig. 8, the susceptor 30d has a tubular shape and has two identical indentations 33d extending from the lower end towards the upper end, so as to divide the susceptor 30d into two parts, namely a left half 310d and a right half 320d in fig. 7, located between the two indentations 33d in the circumferential direction; while connecting the first and second leads 31d and 32d to the left and right halves 310d and 320d, respectively, at positions near or at the lower ends thereof, thereby forming a circuitous current path as shown by arrows in fig. 7.
In yet another preferred embodiment, the first pins 31/31a/31b/31c and the second pins 32/32a/32b/32c are made of a material having a temperature coefficient of resistance, such as common thermocouple wires including nickel-iron-copper alloy, nickel-chromium-aluminum alloy, nickel-chromium-copper alloy, platinum, tungsten, etc.; then during testing, the combined resistance values of the susceptors 30/30a/30b/30c and the first pins 31/31a/31b/31c and the second pins 32/32a/32b/32c are tested, which enables the resistance and temperature sensing results to be improved by amplifying the resistance of the susceptors 30/30a/30b/30c during testing. In practice, since the first pins 31/31a/31b/31c and/or the second pins 32/32a/32b/32c with temperature coefficient of resistance are used to amplify the resistance of the susceptors 30/30a/30b/30c, it is necessary that the first pins 31/31a/31b/31c and/or the second pins 32/32a/32b/32c are of the same type; for example, the susceptor 30/30a/30b/30c having the above ferromagnetic material has a positive temperature coefficient of resistance, and the resistance increases when the temperature increases, and the first lead 31/31a/31b/31c and/or the second lead 32/32a/32b/32c also has a positive temperature coefficient of resistance.
In a more preferred embodiment, in order to avoid the temperature difference between the first leads 31/31a/31b/31c and the second leads 32/32a/32b/32c and the susceptors 30/30a/30b/30c, the first leads 31/31a/31b/31c and the second leads 32/32a/32b/32c are welded to the susceptors 30/30a/30b/30c by an ultrasonic butt welding process during the preparation process, so that the difference is eliminated as much as possible.
Or in a more preferred implementation, the first lead 31 is made of two sections of materials, specifically, as shown in fig. 9, and includes a first portion 311 and a second portion 312 sequentially arranged along the length direction; the first portion 311 is made of a material with a relatively high temperature coefficient of resistance, for example, the common thermocouple wires include nickel-iron-copper alloy, nickel-chromium-aluminum alloy, nickel-chromium-copper alloy, platinum, tungsten, and the like, and are used for amplifying the resistance of the susceptor 30/30a/30b/30c during detection, so as to improve the resistance and the temperature detection result; the second portion 312 is made of a material with low resistivity, so that the temperature of the second portion 312 is lower than that of the first portion 311 in use, thereby preventing thermal damage to the subsequent bonding circuit 20 and the like caused by high temperature; further, the second portion 312 is required to have high electrical conductivity and soldering properties, to facilitate good soldering with the circuit 20, and suitable materials such as gold, silver, copper, etc.
An embodiment of the present invention further provides a method of controlling an aerosol-generating device having the above susceptor 30/30a/30b/30c to generate an aerosol, as shown in fig. 10, comprising the steps of:
s10, providing an alternating current to the inductor L through the first power supply module 22, and exciting the inductor L as a magnetic field generator to generate a changing magnetic field, so that the susceptor 30 generates heat to heat the smokable material a;
s20, supplying the direct current detection voltage to the susceptor 30 through the second power supply module 23;
s30 measuring the resistance value of the susceptor 30 at the dc detection voltage and determining the temperature of the susceptor 30 from the resistance value;
s40, based on the temperature of the susceptor 30 determined above, adjusting at least one of the power, frequency or duty cycle of the alternating current supplied to the inductor L, thereby adjusting the parameters of the generated alternating magnetic field to maintain the susceptor 30 at a preset target temperature.
The aerosol generating device and the susceptor of the utility model have the characteristic of resistance temperature coefficient through the susceptor, so that the temperature of the susceptor can be determined by detecting the resistance of the susceptor in work; compared with a temperature measurement mode of a temperature sensor, the production and the preparation are more convenient, and the temperature measurement effect is more accurate.
