The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] Figure 1 This is a schematic diagram of the electronic atomizing device provided in the embodiments of this application.

[0032] like Figure 1 As shown, the electronic atomizing device 100 includes an atomizer 10 and a power supply assembly 20. The atomizer 10 and the power supply assembly 20 are integrally formed.

[0033] The atomizer 10 includes a sensor 11 and a reservoir (not shown). The reservoir is used to store an atomizable liquid matrix; the sensor 11 is configured to be inductively coupled to an inductor 21 and to heat up when penetrated by a changing magnetic field, thereby heating the liquid matrix to generate an aerosol for inhalation.

[0034] The liquid matrix preferably comprises a tobacco-containing material, which includes volatile tobacco flavor compounds released from the liquid matrix upon heating. Alternatively or additionally, the liquid matrix may comprise non-tobacco materials. The liquid matrix may comprise water, ethanol or other solvents, plant extracts, nicotine solutions, and natural or artificial flavorings. Preferably, the liquid matrix further comprises an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0035] Generally, the sensor 11 can be made of at least one of the following materials: aluminum, iron, nickel, copper, bronze, cobalt, ordinary carbon steel, stainless steel, ferritic stainless steel, martensitic stainless steel, or austenitic stainless steel. In this example, by selecting a suitable material, the sensor 11 is made to have a preset Curie temperature, which is greater than the atomization or evaporation temperature of the liquid matrix. Taking a liquid matrix with an atomization temperature of 250°C as an example, the preset Curie temperature can be 280°C, 290°C, 300°C, 310°C, 320°C, etc., that is, the difference between the preset Curie temperature and the atomization temperature of the liquid matrix is ​​between 30°C and 70°C, preferably between 30°C and 60°C, and more preferably between 40°C and 60°C; in a specific example, the difference between the preset Curie temperature and the atomization temperature of the liquid matrix is ​​50°C. The preset Curie temperature is between 250°C and 450°C, preferably between 250°C and 400°C, and more preferably between 200°C and 350°C.

[0036] The power supply assembly 20 includes an inductor 21, a circuit 22, and a power supply 23.

[0037] Inductor 21 generates a changing magnetic field under alternating current. Inductor 21 includes, but is not limited to, induction coil.

[0038] Power source 23 provides power for operating the electronic atomizing device 100. Power source 23 can be a rechargeable battery or a disposable battery.

[0039] Circuit 22 can control the overall operation of the electronic atomizing device 100. Circuit 22 not only controls the operation of the power supply 23 and the inductor 21, but also controls the operation of other components in the electronic atomizing device 100.

[0040] Understandable, except Figure 1 In addition to the components provided, the electronic atomizing device 100 may also include other components, such as liquid delivery elements. The liquid delivery elements may be made of materials such as cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc. The liquid delivery elements may be rod-shaped, tubular, or rod-shaped, or they may be plate-shaped, sheet-shaped, or concave block-shaped with cavities on the surface, or arch-shaped with an arch structure, etc.

[0041] and Figure 1 Unlike the example, in other examples, the atomizer 10 and the power supply assembly 20 can be formed separately, for example, the atomizer 10 and the power supply assembly 20 can be connected by snap-fit, magnetic connection, etc.

[0042] In order to accurately monitor the working status of sensor 11, Figure 2 and Figure 3 A schematic diagram of the basic components of one embodiment of circuit 22 is shown; circuit 22 includes:

[0043] The magnetic field generating circuit includes a switching circuit 221 and a resonant circuit 222.

[0044] The switching circuit 221 is a half-bridge circuit composed of transistor switches; it includes switching transistors Q1 and Q2, which are used to make the resonant circuit 222 resonate by alternating switching on and off.

[0045] The resonant circuit 222 is composed of an inductor 21 (shown as L in the figure), a first capacitor C1, and a second capacitor C2. The resonant circuit 222 is used to generate an alternating current flowing through the inductor L during the resonance process, thereby causing the inductor L to generate an alternating magnetic field that induces the sensor 11 to heat up.

[0046] The driver 223 is used to control the switching transistors Q1 and Q2 of the switching circuit 221 to alternately turn on and off according to the control signal of the controller (not shown in the figure).

[0047] The driver 223 uses the commonly used FD2204 switching transistor driver, which is controlled by the controller in PWM mode. Based on the PWM pulse width, high and low levels are alternately emitted from I / O ports 3 and 10 to drive the conduction time of switching transistors Q1 and Q2, thereby controlling the resonance of the resonant circuit 222. In other examples, it is also feasible to integrate the driver 223 into the controller or implement it by the controller.

[0048] In terms of connection, the first terminal of the first capacitor C1 is connected to Vbat (Vbat can be power supply 23 or power supply 23 after voltage regulation), and the second terminal is connected to the first terminal of the second capacitor C2; the second terminal of the second capacitor C2 is grounded through resistor R1.

[0049] The first terminal of the switching transistor Q1 in the switching circuit 221 is connected to Vbat, and the second terminal is connected to the first terminal of the switching transistor Q2. The second terminal of the switching transistor Q2 is grounded through resistor R1. Of course, the control terminals of both the switching transistors Q1 and Q2 are connected to the driver 223, and are turned on and off by the driver 223. The switching transistors Q1 and Q2 include, but are not limited to, IGBTs, MOSFETs, etc.

[0050] The first terminal of inductor L is connected to the second terminal of switching transistor Q1, and the second terminal is connected to the second terminal of first capacitor C1. Meanwhile, in the hardware selection of resonant circuit 222, the voltage ratings of the first capacitor C1 and the second capacitor C2 are much higher than the output voltage of power supply 23. For example, in typical implementations, the output voltage of power supply 23 is approximately 4V, while the voltage ratings of the first capacitor C1 and the second capacitor C2 are 30–80V.

[0051] In the resonant circuit 222 described above, the connection state of the first capacitor C1, the second capacitor C2, and the inductor L changes depending on the switching states of the switching transistors Q1 and Q2. When the switching transistor Q1 is on and the switching transistor Q2 is off, the first capacitor C1 and the inductor L together form a closed LC series circuit, while the second capacitor C2 and the inductor L form an LC series circuit with its two ends connected to Vbat and ground respectively (this circuit starts at Vbat, passes through the inductor L and the second capacitor C2 in sequence, and ends at the ground terminal). When the switching transistor Q1 is off and the switching transistor Q2 is on, the circuit formed is the opposite of the above states. The first capacitor C1 and the inductor L form an LC series circuit with its two ends connected to Vbat and ground respectively, while the second capacitor C2 and the inductor L together form a closed LC series circuit. In their respective states, the first capacitor C1 and the second capacitor C2 can each form their own LC series circuit with the inductor L.

[0052] To accurately detect details such as the oscillation process and period of the resonant circuit 222, see [link / reference]. Figure 4 As shown, the implementation also includes a detection circuit, whose function is to synchronously detect changes in physical parameters such as current, voltage, or period during the resonance process of the resonant circuit 222. Specifically... Figure 4 In the illustrated embodiment, the synchronization detection circuit includes an operational amplifier U1, and the signal input terminal for detection is connected to the second terminal of the inductor L (shown as JC in the figure). In an optional implementation, the reference signal terminal of the operational amplifier U1 is directly set to 0, making it a zero-crossing comparator used to detect the moment when the resonant current of the resonant circuit 222 is 0. The controller then uses this detection result combined with the zero-crossing time point to obtain the physical parameters of the resonant circuit 222, such as current, voltage, or period changes. It should be noted that the current sampling of the resonant circuit 222 can also employ a high-side current detection method (with the sampling resistor set between Vbat and the resonant circuit 222) or a low-side current detection method (with the sampling resistor set between the resonant circuit 222 and the ground terminal).

[0053] like Figure 5 As shown, in another embodiment, the resonant voltage of the resonant circuit 222 (shown as V11 in the figure) can be divided by an RC integrator circuit composed of D11, R16, and C13, and then by a voltage divider circuit composed of R11 and R14 before being input to the negative input terminal of comparator U11. When the voltage at the negative input terminal of comparator U11 is higher than the voltage at the positive input terminal, comparator U11 outputs a low level (OUT terminal in the figure); otherwise, it outputs a high level. The controller can control the power supply of power supply 23 according to the output level of comparator U11. Comparator U11 can be integrated into the controller or can be independent of the controller.

[0054] In one example, the sensor 11 is made of a material with a preset Curie temperature. As the temperature of the sensor 11 gradually approaches its Curie temperature, the magnetism of the material gradually disappears. At this time, the magnetic coupling coefficient between the inductor L and the sensor 11 gradually decreases, and the Q (quality factor) value of the magnetic field generating circuit gradually increases. Consequently, the electrical characteristic parameters of the magnetic field generating circuit, such as the resonant voltage and current values, will change accordingly. Therefore, the controller can determine whether the sensor 11 is under unfavorable conditions based on the electrical characteristic parameters of the magnetic field generating circuit, and thus control the power supply of the power source 23; for example, if the sensor 11 is under unfavorable conditions, the power supply of the power source 23 to the magnetic field generating circuit can be turned off or limited. Figure 6 For example, Figure 6 The horizontal axis represents the temperature of sensor 11, and the vertical axis represents the peak resonant voltage of the magnetic field generating circuit. When the temperature of sensor 11 is T0, since its temperature has not reached the Curie temperature T2, the magnetic coupling coefficient between inductor L and sensor 11 is relatively large, the Q value of the magnetic field generating circuit is relatively small, and the peak resonant voltage V0 of the magnetic field generating circuit is also relatively small. When the temperature of sensor 11 is the Curie temperature T2, the magnetic coupling coefficient between inductor L and sensor 11 is relatively small, the Q value of the magnetic field generating circuit is relatively large, and the peak resonant voltage V2 of the magnetic field generating circuit is also relatively large. Based on this relationship between the peak resonant voltage and temperature, the controller can monitor the peak resonant voltage of the magnetic field generating circuit and determine whether sensor 11 has adverse conditions based on the peak resonant voltage. For example, if the peak resonant voltage V1 of the magnetic field generating circuit is detected to reach V2, it can be determined that sensor 11 has adverse conditions, and the power supply of power supply 23 to the magnetic field generating circuit can be turned off or limited.

[0055] In another example, due to differences in the material, size, volume, and other factors of the sensor 11, the magnetic coupling coefficient between different sensors 11 and the inductor L is different, resulting in different Q values ​​for the magnetic field generating circuit, and corresponding different resonant voltage and current values. Based on this situation, the controller can monitor the electrical characteristic parameters of the magnetic field generating circuit to determine if there are any adverse conditions on the sensor 11. For example, the atomizer 10 coupled to the power supply assembly 20 may be counterfeit, substandard, or damaged.

[0056] In another example, the atomizer 10 is connected before and after the power supply assembly 20, and the Q value of the magnetic field generating circuit is different, resulting in different resonant voltage and current values. Based on this situation, the controller can monitor the electrical characteristic parameters of the magnetic field generating circuit to determine if there are any adverse conditions on the sensor 11. For example, the atomizer 10 may be connected to the power supply assembly 20 or removed from the power supply assembly 20.

[0057] One disadvantage of the receptor 11 in a specific implementation is the insufficiency or depletion of the liquid matrix supplied to or delivered to the receptor 11. Generally, when a constant power or electricity is supplied to the receptor 11, the less liquid matrix is ​​supplied or delivered to the receptor 11, the higher the temperature of the receptor 11.

[0058] In another implementation, a disadvantage of the sensor 11 is that its operating parameters, such as temperature and voltage, exceed the expected normal values. That is, the operating state of the sensor 11 is outside the expected normal range, which may pose a safety risk.

[0059] In another variation, a disadvantage of the sensor 11 is that the atomizer 10 is not coupled to (connected to) the power supply assembly 20, or that other foreign objects are coupled to the power supply assembly 20. Similar to the aforementioned, when the atomizer 10 is not coupled to the power supply assembly 20, the magnetic coupling coefficient between the inductor L and the sensor 11 is small; when the atomizer 10 is coupled to the power supply assembly 20, the magnetic coupling coefficient between the inductor L and the sensor 11 will increase, and the Q (quality factor) value of the corresponding magnetic field generating circuit will decrease. If other foreign objects are coupled to the power supply assembly 20, and if there is magnetic coupling between the foreign object and the sensor 11, then under a given power, it will not have the same operating parameters or characteristics (e.g., voltage, current) as the standard sensor 11; if there is no magnetic coupling between the foreign object and the sensor 11, then the magnetic coupling coefficient before and after coupling remains unchanged.

[0060] In yet another variation, a disadvantage of the sensor 11 is that the atomizer 10 coupled to the power supply assembly 20 is counterfeit, substandard, or damaged. A counterfeit, substandard, or damaged atomizer 10 does not possess the same operating parameters or characteristics (e.g., voltage, current) as a standard sensor 11 under a given power condition.

[0061] In another unfavorable implementation, the liquid matrix supplied by the atomizer 10 to the sensor 11 is undesirable; specifically, the undesirable liquid matrix may have different composition from the desired liquid matrix, resulting in different viscosity, heat capacity, or boiling point, etc., thus having a higher or lower temperature or power or electricity in the heated atomization than expected.

[0062] exist Figure 3 In the illustrated embodiment, the electrical characteristic parameters of the magnetic field generating circuit include the resonant voltage value of the resonant circuit 222, such as the peak resonant voltage.

[0063] Based on the resonant voltage value detected by the synchronous detection circuit:

[0064] In one embodiment, the controller is further configured to determine whether the sensor 11 is under adverse conditions based on a comparison between the resonant voltage value and a preset threshold. For example, if the liquid matrix supplied to or delivered to the sensor 11 is insufficient or depleted, the resonant voltage value is compared with the preset threshold. If the resonant voltage value is greater than the preset threshold, it can be determined that the sensor 11 is in an overheated state, resulting in dry burning.

[0065] In one embodiment, the controller is further configured to determine whether there are adverse conditions for the sensor 11 based on the amount or rate of change of the resonant voltage value of the magnetic field generating circuit within a predetermined time period. For example, during the suction process, if the amount or rate of change of the resonant voltage value ΔV within a predetermined time t1 exceeds a preset threshold range, it can be used to determine whether there are adverse conditions for the operation of the sensor 11; the predetermined time can be an empirical value or an experimental value, and is not limited here.

[0066] In one embodiment, the controller is configured to determine whether the sensor 11 has an adverse condition based on the ratio (ΔV / V0) between the change in the resonant voltage value of the magnetic field generating circuit relative to its initial value. Specifically, a threshold value suitable for normal operation can be selected based on the ΔV / V0 ratio; when the ΔV / V0 ratio is greater than the threshold value, an adverse condition is determined to exist.

[0067] In one embodiment, the controller is further configured to determine whether the sensor 11 has adverse conditions based on a comparison between the duration for which the resonant voltage value of the magnetic field generating circuit reaches a preset threshold from its initial value and a preset time threshold. For example, under a given power, a magnetic field generating circuit containing a standard sensor 11 can reach the preset threshold within a expected time period, while a counterfeit, substandard, or damaged atomizer 10 will only reach the preset threshold after a period exceeding the expected time period; thus, it can be determined that the sensor 11 has adverse conditions. The initial value is not limited and can be zero or a value between zero and the peak value of the resonant voltage. In some optional embodiments, the expected time period is, for example, 50ms to 200ms; or it can be 80ms to 200ms, etc.; or in some preferred embodiments, the expected time period is between 50ms and 150ms.

[0068] In one embodiment, the controller is further configured to stop the power supply to the power source 23 when the number of adverse conditions in the sensor 11 exceeds a preset threshold.

[0069] It should be noted that the above example only uses an LCC series resonant circuit for illustration; in other examples, it can also be an LC series resonant circuit (including but not limited to half-bridge series resonance, full-bridge series resonance), an LC parallel resonant circuit, etc.

[0070] It should be noted that the above example only uses the resonant voltage of the magnetic field generating circuit as an example. It is conceivable that the electrical characteristic parameters of the magnetic field generating circuit include at least one of the following: current value, quality factor Q, resonant frequency, inductance value, and electrical characteristic parameters derived from the aforementioned parameters. These electrical characteristic parameters can be directly measured or calculated.
