All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.
In the description of the present application, it is to be understood that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
The temperature measuring circuit provided by the embodiment of the application can be applied to eddy current induction and air heating equipment. For example, the temperature measuring circuit provided by the embodiment of the application can be applied to an electronic smoking set. The following description will take an example in which the temperature measuring circuit is applied to an electronic smoking set.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a temperature measuring circuit according to an embodiment of the present disclosure. As shown in fig. 1, a temperature measurement circuit 10 provided in the embodiment of the present application includes: a heating element 101, a resonance unit 102, and a main control unit 103. The resonance unit 102 is connected to the supply voltage V and coupled to the heating element 101, and the resonance unit 102 is configured to provide a magnetic field to the heating element 101 based on the supply voltage V, so that the heating element 101 generates heat. The main control unit 103 is connected to the resonance unit 102, and the main control unit 103 is configured to detect a resonance frequency of the resonance unit 102 and obtain a temperature of the heating element 101 based on the resonance frequency.
Since the heating body 101 is coupled to the resonance unit 102, that is, the heating body 101 is detachably disposed in the resonance unit 102, the heating body 101 can be easily replaced after being used for a certain period of time. Further, the temperature measuring circuit 10 can acquire the temperature of the heating body 101 without setting a temperature sensor, so that the production cost of the electronic smoking set can be reduced, and the assembly difficulty of the electronic smoking set can be reduced.
The heating element 101 is made of a magnetic material. The magnetic material is composed of a ferromagnetic substance or a ferrimagnetic substance. In one embodiment, the heating element 101 is made of a magnetic material, and the main control unit 103 detects the resonant frequency of the resonant unit 102 to obtain the change of the magnetic permeability of the magnetic material. In another embodiment, the heating element 101 includes a heating body and a magnetic material disposed on an outer surface of the heating body, and the main control unit 103 detects a resonant frequency of the resonant unit 102 to obtain a change in magnetic permeability of the magnetic material. That is, in practical application, the heating element can be directly made of magnetic material; the outer surface of the heating element may be coated with a magnetic material in addition to the conventional heating element.
The magnetic permeability of the magnetic material and the temperature of the magnetic material are in a preset proportional relation in a preset temperature range. In one embodiment, the magnetic material may be ferrite. Specifically, referring to fig. 2, fig. 2 is a graph illustrating a magnetic permeability and a temperature variation curve of ferrite in the temperature measuring circuit according to the embodiment of the present application. As shown in fig. 2, the permeability of ferrite varies with temperature. Wherein, the magnetic conductivity of the ferrite and the temperature of the ferrite are in a linear relation in a preset temperature range. Since the magnetic permeability of the ferrite changes greatly with temperature, the temperature measuring circuit 10 can accurately obtain the temperature of the heating element 101 without setting a temperature sensor by using the magnetic material ferrite in the embodiment of the present application.
The heating element 101 of the embodiment of the present application can generate heat in a magnetic field regardless of the type in which the heating element 101 is directly made of a magnetic material or the type in which a magnetic material is coated on the outer surface of the heating element in addition to the conventional heating element.
For example, please refer to fig. 3, fig. 3 is a schematic diagram illustrating a heating principle of a temperature measuring circuit according to an embodiment of the present disclosure. As shown in fig. 3, when a heating element 101 is placed in an induction coil 111 and a current is input to the induction coil 111, an alternating magnetic field is generated in the induction coil 111. Since the heating element 101 in the middle of the induction coil 111 is a closed circuit equivalent to one turn in the circumferential direction, and the magnetic flux B in the closed circuit is constantly changed, an induced electromotive force and an induced current are generated in the circumferential direction of the heating element 101, and the direction of the current is rotated in the circumferential direction of the heating element 101 like a swirl of one turn, so that the phenomenon that the electromagnetic induction is generated inside the entire heating element 101 to generate the induced current is called an eddy current phenomenon. The induced current flows inside the metal, and the electric energy is converted into heat energy by overcoming the resistance thereof, thereby causing the heating body 101 to generate heat.
In addition, the magnetic permeability of the heating element 101 can represent the temperature of the heating element 101, that is, the temperature measuring circuit 10 according to the embodiment of the present application can obtain the temperature corresponding to the heating element 101 through the magnetic permeability of the heating element 101, so that the temperature measuring circuit 10 according to the embodiment of the present application can obtain the temperature of the heating element 101 without providing a temperature sensor.
The temperature measuring circuit 10 of the embodiment of the present application can obtain the magnetic permeability of the heating element 101 through an inductance value calculation formula and a resonance frequency calculation formula. Wherein, the inductance value formula is: l is 0.4 pi μ Ae/Le N2, L is an inductance value of the induction coil in the resonance unit 102, μ is a magnetic permeability of the heating element 101, Ae is a core cross-sectional area of the induction coil in the resonance unit 102, Le is a magnetic path length of the induction coil in the resonance unit 102, and N is a number of turns of the induction coil in the resonance unit 102. The resonant frequency calculation formula is: f is 1/(2 × pi (L × C)0.5), f is the resonance frequency of the resonance unit 102, and C is the capacitance value of the capacitor in the resonance unit 102.
That is, the main control unit 103 in the temperature measurement circuit 10 provided in this embodiment of the application may first obtain the inductance value of the induction coil in the resonance unit 102 according to the resonant frequency calculation formula, then obtain the magnetic permeability of the heating element 101 according to the inductance value calculation formula, and finally obtain the temperature of the heating element 101 based on the magnetic permeability of the heating element 101 by detecting the resonant frequency of the resonance unit 102.
In one embodiment, please refer to fig. 4 and 5, wherein fig. 4 is a circuit diagram of a temperature measuring circuit according to an embodiment of the present disclosure. Fig. 5 is a schematic position diagram of a magnetic induction coil and a heating element in a temperature measuring circuit provided in an embodiment of the present application. As shown in fig. 1, 4 and 5, the resonant unit 102 includes a first inductor L1, a second inductor L2, a magnetic induction coil L3, a capacitor C1, a resistor R1, a first transistor Q1 and a second transistor Q2. One end of the first inductor L1 and one end of the second inductor L2 are both connected to the power supply voltage V, the other end of the first inductor L1, one end of the capacitor C1, one end of the magnetic induction coil L3, the source of the first transistor Q1 and the gate of the second transistor Q2 are electrically connected, the other end of the second inductor L2, the other end of the capacitor C1, the other end of the magnetic induction coil L3, the source of the second transistor Q2 and the gate of the first transistor Q1 are electrically connected, the drain of the first transistor Q1, the drain of the second transistor Q2 and one end of the resistor R1 are all connected to the main control unit 103, and the other end of the resistor R1 is grounded. The magnetic induction coil L3 is fitted over the heating element 101 and insulated from the heating element 101.
When the temperature measuring circuit 10 of the embodiment of the application works, after the temperature of the heating element 101 changes, the magnetic permeability of the heating element 101 changes correspondingly, the inductance value of the induction coil L3 also changes correspondingly, a detection point is arranged on the resonance unit 102, and the main control unit 103 detects the slope change of the voltage waveform of the resistor R1 at the detection point, so that the resonance frequency of the resonance unit 102 can be detected.
Specifically, the main control unit 103 detects the slope change of the voltage waveform of the resistor R1 at the detection point, so as to obtain the resonant frequency of the resonant unit 102. Then, since the resonant frequency of the resonant unit 102 and the capacitance of the capacitor C1 in the resonant unit are known, the inductance of the inductor L3 in the resonant unit 102 can be obtained based on the resonant frequency calculation formula. Next, since the core sectional area, the magnetic path length, and the number of turns of the induction coil in the resonance unit 102 are known, the magnetic permeability of the heating body 101 coupled to the induction coil L3 in the resonance unit 102 at this time can be obtained based on the inductance value calculation formula. Finally, the temperature of the heating element 101 is obtained based on the magnetic permeability of the heating element 101.
In one embodiment, a power module may be additionally disposed in the electronic smoking set, and the power module is only used for providing the power supply voltage V. That is, the power module only needs to provide the power supply voltage V, the efficiency is high, and when other power modules of the electronic smoking set are damaged, the electronic smoking set is not damaged greatly.

Wherein the switching unit 104 is arranged between the access voltage V and the resonance unit 102. The input end of the switch unit 104 is connected to the supply voltage V, the control end of the switch unit 104 is connected to the main control unit 103, and the output end of the switch unit 104 is connected to the resonance unit 102.
In one embodiment, the switching unit 104 may be a transistor. Specifically, the gate of the transistor is connected to the main control unit 103, the source of the transistor is connected to the supply voltage V, and the drain of the transistor is connected to the resonance unit 102. The transistors used in the embodiments of the present application may be thin film transistors or field effect transistors or other devices with the same characteristics, and since the sources and drains of the transistors used herein are symmetric, the sources and drains may be interchanged. In the embodiment of the present application, to distinguish two poles of a transistor except for a gate, one of the two poles is referred to as a source, and the other pole is referred to as a drain. The form in the drawing provides that the middle end of the switching transistor is a grid, the signal input end is a source, and the output end is a drain. In addition, the transistors used in the embodiments of the present application may include a P-type transistor and/or an N-type transistor, where the P-type transistor is turned on when the gate is at a low level and turned off when the gate is at a high level, and the N-type transistor is turned on when the gate is at a high level and turned off when the gate is at a low level.

In an embodiment, the main control unit 103 may be a pulse width modulation chip. The pulse width modulation chip can refer to the existing pulse width modulation chip and adjust the waveform correspondingly.
Specifically, when the temperature measuring circuit 20 works, the main control unit 103 outputs a signal PWM after detecting the behavior of the heating indication button, thereby controlling the on/off of the switch unit 104. When the switching unit 104 is turned on, the supply voltage V is input to the resonance unit 102, and the resonance unit 102 converts the supply voltage V into an alternating current and generates an alternating magnetic field by self-excitation. The heating element 101 generates heat energy according to the electromagnetic induction and the heat effect of the current, thereby heating the cigarette. Meanwhile, the main control unit 103 detects the slope change of the voltage waveform at the detection point, so as to obtain the resonant frequency of the resonant unit 102. Then, the magnetic permeability of the heating element 101 at this time can be obtained based on the resonance frequency calculation formula and the inductance value calculation formula. Subsequently, the temperature of the heating element 101 is obtained based on the magnetic permeability of the heating element 101. Finally, the main control unit 103 adjusts the duty ratio of the signal PWM based on the temperature of the heating element 101. When the temperature of the heating element 101 is too low, the main control unit 103 outputs a signal PWM with a high duty ratio to heat the heating element 101; when the temperature of the heating element 101 is too high, the main control unit 103 outputs a signal PWM with a low duty ratio to heat the heating element 101.
