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

[0040] Figure 1 It is a schematic diagram of the electronic atomization device provided in an embodiment of the present application.

[0041] like Figure 1 As shown, the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20 .

[0042] In one example, the atomizer 10 is removably connected to the power supply assembly 20 , and the atomizer 10 and the power supply assembly 20 may be snap-connected, magnetically connected, or the like.

[0043] In one example, the atomizer 10 and the power supply assembly 20 are not detachable, that is, they are integrally formed.

[0044] The atomizer 10 includes a sensor 11 and a liquid storage chamber A.

[0045] Liquid storage chamber A is used to store atomizable liquid matrix; Liquid matrix preferably comprises tobacco-containing material, and the material containing tobacco is included in the volatile tobacco flavor compound released from liquid matrix when heating.Alternately or in addition, liquid matrix can comprise non-tobacco material.Liquid matrix can comprise water, ethanol or other solvent, plant extract, nicotine solution and natural or artificial flavoring agent.Preferably, liquid matrix further comprises aerosol forming agent.The example of suitable aerosol forming agent is glycerine and propylene glycol.

[0046] The susceptor 11 is configured to be able to be penetrated by the changing magnetic field and generate heat, so as to heat the liquid matrix from the liquid storage chamber A and generate an inhalable aerosol.

[0047] The receptor 11 includes a substrate and a conductor bonded to at least part of the substrate, wherein the substrate is made of a magnetically conductive non-conductive material. The substrate can distort or gather at least part of the magnetic lines of force in the magnetic field to increase the magnetic flux passing through the conductor, thereby increasing the eddy current loss of the conductor, that is, generating more heat; thus, the heating efficiency of the receptor is improved, and the user experience is enhanced. Since the substrate is made of a magnetically conductive non-conductive material, the heat generated by the eddy current effect under the penetration of the magnetic field is extremely small.

[0048] A susceptor composed of a substrate made of a magnetically conductive non-conductive material and a conductor bonded to at least a portion of the substrate has a heating efficiency greater than that of a susceptor formed solely of a conductor. In order to better understand the present application, the following verification and explanation are made from different perspectives:

[0049] Before adopting this solution, as shown in the following table, the sensor (whose heat generation may be caused by eddy current and / or hysteresis loss) is placed in the spiral induction coil. In the mass column of the table, Air means that the spiral induction coil is in an unloaded state, no sensor is coupled with the induction coil, the number of turns of the coil is about 9 turns, and the length is about 10 mm; the specific data means that the sensor of this mass is placed in the spiral induction coil for coupling, for example: "4 mg" means that a sensor of 4 mg is placed in the spiral induction coil for coupling. The conversion efficiency is calculated by the following formula: η=1-Rs(Air) / Rs(mg), where Rs(Air) represents the resonant resistance of the resonant circuit in the unloaded state, and Rs(mg) represents the resonant resistance of the resonant circuit in the loaded state, that is, the state in which the sensor is coupled with the induction coil. For example, when the mass of the sensor is 4 mg, its conversion efficiency η=1-25.8 / 41.8=38.3%.

[0050]

[0051]

[0052] It can be seen from the table that the larger the mass of the receptor, the greater its conversion efficiency η; but the problem that comes with it is that, under the condition of the same energy provided to the receptor, the larger the mass of the receptor, the slower the temperature rise rate or fall rate of the receptor. If the target temperature of the receptor is reached, the power consumption required to be provided to the receptor is also large, which leads to a decrease in the battery life; during continuous puffing, the high cumulative temperature is easy to affect the puffing taste. On the contrary, the smaller the mass of the receptor, the smaller the space occupied by the receptor in the magnetic field, so there are fewer magnetic lines of force passing through the receptor, resulting in a smaller conversion efficiency η. There may be a phenomenon that the amount of aerosol (TPM) generated by the receptor heating the liquid matrix is ​​relatively small or that no smoke is produced by atomization in the early stage of puffing. However, the smaller the mass of the receptor means that the temperature of the receptor rises or falls faster under the same energy supply conditions, and the heat source is more concentrated. During continuous puffing, the puffing taste will not be affected by the high cumulative temperature. The purpose of this application is to balance the above two technical problems and propose a new solution, which can not only improve the conversion efficiency η of the sensor to reduce the power consumption of the sensor, but also increase the temperature rise rate of the sensor to stabilize the output aerosol amount (TPM) at the desired target.

[0053] Referring to the table above, taking the frequency f as 1.1Mhz as an example, the conversion efficiency η of a susceptor with a mass of 7.5mg coupled in a magnetic field is 75.04%. The susceptor needs about 10W of power consumption to raise the temperature of the liquid matrix to the temperature required for atomization, such as 250°C, within 0.5S. The power required by the heating component (susceptor + spiral induction coil) is about 10W / 0.7504=13.33W, and the current of the spiral induction coil is The resonant voltage is about 150V, so the required input power is about 23.5W. The conversion efficiency of the sensor's working power to the input power is only 10W / 23.5W≈43%.

[0054] After adopting the following embodiment scheme of the present application, the magnetic field is gathered or distorted by the substrate to increase the magnetic flux passing through the conductor, and the magnetic lines of force generated by the spiral induction coil can be more coupled to the conductor, thereby greatly improving the conversion efficiency η of the receptor, so that the power provided to the resonant circuit is also smaller, thereby improving the endurance of the battery cell; at the same time, in this embodiment scheme, a conductor with a smaller mass can be used, and under the same energy supply conditions, the temperature of the receptor rises or falls faster, the heat source is more concentrated, the atomization speed is faster, and the puffing taste will not be affected by the high accumulated temperature during continuous puffing.

[0055] Taking the following table data as an example, a conductor with a mass of 4 mg is combined with a substrate of about 10 mm to form a sensor, and the conversion efficiency η of the sensor can be increased to 91.8%. In the actual measurement of the installation, the temperature of the liquid matrix is ​​raised to the temperature of 250°C required for atomization within 0.5S, the input power is only 9.237W (constant power output), and the TPM value is stable between 6-7. In some examples, the conductor can be combined with the substrate by etching, coating, and deposition; the conductor can also be combined with the substrate by installation or the substrate can be directly or indirectly installed on the conductor. As an optional example, the conductor is located in the middle area of ​​the substrate along the length direction (magnetic line direction) and is spaced a certain distance from both ends of the conductor; as a suitable example, the substrate is arranged to be surrounded by the conductor or the substrate is surrounded by the periphery of the local surface of the conductor. In other examples, the substrate can be in contact or non-contact with the conductor, for example, the substrate can be non-contact with the conductor, which is beneficial for reducing the heat transfer from the conductor to the substrate, thereby increasing the temperature rise rate of the conductor.

[0056]

[0057] In one example, the mass of the conductor is between 1 mg and 15 mg; preferably, between 1 mg and 12 mg; preferably, between 1 mg and 10 mg; preferably, between 1 mg and 9 mg; preferably, between 1 mg and 8 mg; in specific examples, it can be 2 mg, 4 mg, 6 mg, 8 mg, 8.5 mg, etc.

[0058] In one example, the conductor is bonded to a portion of the substrate; preferably, the conductor is bonded to a portion of the surface of the substrate.

[0059] Due to the improvement of heating efficiency, the volume of the conductor can be relatively smaller and lighter, which can, on the one hand, facilitate more concentrated heat, and on the other hand, reduce the power loss of the electronic atomization device 100 and improve battery life.

[0060] Furthermore, since the heat is concentrated in the conductor installation area of ​​the substrate, the heat of other areas of the substrate is smaller than that of the conductor installation area. Therefore, the temperature difference between different areas of the substrate is conducive to the atomization of different components in the liquid matrix, improving the user's smoking experience.

[0061] Furthermore, the surface of the conductor may be coated with a first protective layer, which may be formed of glass, ceramic or inert metal. The first protective layer can at least prevent the conductor from being corroded.

[0062] In one example, the conductor is paramagnetic. In this case, the heat generation in the conductor is caused only by eddy currents. Of course, the conductor can also be magnetic, and heat can also be generated in the conductor through hysteresis losses.

[0063] In one example, the conductor includes at least one of stainless steel, aluminum, and bronze. Preferably, the conductor is made of stainless steel, which has a lower resistivity and a larger current flowing therethrough, thereby improving the heating efficiency of the sensor.

[0064] In one example, the conductor is bonded to at least a portion of the substrate by at least one of etching, coating, plating, deposition coating, or direct mounting.

[0065] In one example, the conductor includes a conductive track coupled to at least a portion of the substrate. The conductive track may be a conductive line extending in a meandering manner on the substrate. It may also be a conductive grid in a mesh shape. It is understood that it is also feasible that the conductor is a continuous body coupled to at least a portion of the substrate; a continuous body means that there is no mesh-like structure.

[0066] Furthermore, at least part of the surface of the substrate may be coated with a second protective layer, which may be formed of glass, ceramic or inert metal. The second protective layer can prevent the substrate from contacting the liquid matrix, thereby preventing harmful substances of the substrate from being released into the liquid matrix, thereby improving the safety of the liquid matrix.

[0067] In one example, the substrate includes a ferromagnetic or ferrimagnetic material. The ferromagnetic or ferrimagnetic material can make the magnetic permeability of the substrate higher, which is beneficial to increase the magnetic flux of the conductor.

[0068] In one example, the matrix includes at least one of manganese zinc ferrite, manganese magnesium ferrite, nickel zinc ferrite or cobalt zinc barium ferrite.

[0069] In one example, since the substrate is non-conductive, the heat generation of the substrate (excluding the heat transferred from the conductor to the substrate) is caused only by hysteresis loss. When the Curie temperature of the substrate is reached, the heat generation in the substrate stops completely.

[0070] The temperature of the susceptor can be controlled by matching the Curie temperature of the substrate with the preset operating temperature of the electronic atomization device 100. Generally, the Curie temperature of the substrate material ranges from 150°C to 400°C, or from 150°C to 380°C, or from 150°C to 360°C, or from 150°C to 300°C, or from 150°C to 280°C, or from 200°C to 280°C.

[0071] In one example, the substrate is configured to absorb the liquid matrix in the liquid storage chamber A and transfer the absorbed liquid matrix to the conductor. For example, the substrate is configured to be a porous structure, and the liquid matrix absorbs the liquid matrix through the capillaries of the substrate and transfers the absorbed liquid matrix to the conductor. In this case, the substrate integrates multiple functions in one, and the receptor 11 can directly contact the liquid matrix, thereby evaporating the liquid matrix by releasing heat.

[0072] In one example, the electronic atomization device 100 further includes a liquid transfer unit configured to transfer the liquid matrix to the receptor;

[0073] The receptor is disposed on the surface of the liquid transfer unit or is at least partially embedded in the liquid transfer unit.

[0074] The liquid transfer unit may be, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc., and can transfer the liquid matrix stored in the liquid storage chamber A to the receptor 11 through capillary action.

[0075] In one example, the substrate is configured as a tube, rod, sheet or plate structure.

[0076] The power supply assembly 20 includes a magnetic field generator 21 , a circuit 22 and a battery cell 23 .

[0077] The magnetic field generator 21 is configured to generate a changing magnetic field under an alternating current. The magnetic field generator 21 includes a single induction coil or multiple induction coils. The induction coil or multiple induction coils may have a shape that matches the susceptor. Similarly, the induction coil or multiple induction coils conform to the shell shape of the aerosol generating device. For example, the induction coil or multiple induction coils may be a spiral coil or a flat spiral coil.

[0078] The circuit 22 can control the overall operation of the electronic atomization device 100. The circuit 22 not only controls the operation of the battery cell 23 and the magnetic field generator 21, but also controls the operation of other components in the electronic atomization device 100.

[0079] In one example, the frequency of the alternating current supplied by the circuit 22 to the magnetic field generator 21 is between 500KHz and 3MHz; preferably, the frequency may be between 500KHz and 2.5MHz; further preferably, the frequency may be between 500KHz and 2MHz; further preferably, the frequency may be between 500KHz and 1.5MHz; further preferably, the frequency may be between 500KHz and 1MHz. For example, the frequency of the alternating current supplied by the circuit 22 to the magnetic field generator 21 is 500KHZ, or 600KHZ, or 800KHZ, or 1.2MHZ.

[0080] The battery cell 23 provides power for operating the electronic atomization device 100. The battery cell 23 may be a rechargeable battery cell or a disposable battery cell.

[0081] Figure 2 It is a schematic diagram of a receptor provided in an embodiment of the present application.

[0082] like Figure 2 As shown, the susceptor 11 includes a substrate 11a and a conductor 11b. The substrate 11a is configured as a cylindrical structure. The conductor 11b is combined on the outer side wall of the substrate 11a. The axial length of the conductor 11b is smaller than the axial length of the substrate 11a.

[0083] The substrate 11a is non-conductive. The substrate 11a is made of manganese-zinc ferrite, and the initial magnetic permeability of the manganese-zinc ferrite is about 3000H / m, and the maximum magnetic permeability is about 6000H / m. The conductor 11b is made of stainless steel material, preferably SUS430 stainless steel. The resistivity of the conductor 11b is much smaller than the resistivity of the substrate 11a (the resistivity of manganese-zinc ferrite is about 5E+07μΩ·cm, while the resistivity of SUS430 stainless steel is about 0.6μΩ·cm).

[0084] Figure 3 is another sensor schematic diagram provided in the embodiment of the present application. Figure 2 The difference in the example is that Figure 3 In the example, the conductor 11b is a discontinuous body and has meshes.

[0085] Figure 4 is another sensor schematic diagram provided in the embodiment of the present application. Figure 2 The difference in the example is that Figure 4 In the example shown in FIG. 1 , the base body 11 a is configured as a sheet-like or plate-like structure.

[0086] Figure 5 is another sensor schematic diagram provided in the embodiment of the present application. Figure 4 The difference in the example is that Figure 5 In the example of , the substrate 11a is configured such that along the extension direction from the upper end of the substrate 11a to the lower end of the substrate 11a, the side of the substrate 11a is generally in an arc shape. The upper and lower surfaces of the substrate 11a are both continuous surfaces, and the continuous surface is a complete surface that is uninterrupted or has no grooves or holes. The conductor 11b is combined with the upper surface and / or the lower surface of the substrate 11a and is arranged in the middle part of the substrate 11a.

[0087] The width dimension of the upper and lower ends of the substrate 11a is greater than the width dimension of the middle part of the substrate 11a. Specifically, the width dimension of the upper end of the substrate 11a is d1, the width dimension of the middle part of the substrate 11a is d2, and the width dimension of the lower end of the substrate 11a is d3, and both d1 and d3 are greater than d2. In a preferred implementation, the size of d1 and d3 are the same. The size of d2 is between one-third and two-thirds of d1 (or d3), and the preferred size of d2 is one-half of d1 (or d3). The size of d2 is between 0.1mm and 5mm; preferably between 0.1mm and 4mm; preferably between 0.1mm and 2mm; preferably between 0.5mm and 2mm; in a specific example, it can be 0.7mm. The length dimension of the substrate 11a is between 1mm and 15mm; preferably between 1mm and 12mm; preferably between 1mm and 10mm; preferably between 2mm and 10mm; in a specific example, it can be 6mm. The thickness of the substrate 11a is between 0.02 mm and 0.15 mm; preferably between 0.02 mm and 0.12 mm; preferably between 0.02 mm and 0.1 mm; preferably between 0.04 mm and 0.1 mm; preferably between 0.06 mm and 0.1 mm.

[0088] On the one hand, the substrate 11a of such a shape is conducive to increasing the concentration of magnetic lines of force in the middle part of the receptor, thereby increasing the current density on the conductor 11b located in this part. When the receptor is working, the current density in the middle part is greater than the current density at both ends, so that the temperature rise rate in the middle part of the receptor is greater than the temperature rise rate at both ends. In this way, the heat generated by the receptor is more concentrated, which is conducive to reducing the energy consumed by raising the temperature of the receptor to the desired atomization temperature; on the other hand, the shape of the special-shaped substrate 11a can reduce the volume and mass of the conductor 11b, so that the energy required for the receptor to reach the atomization temperature is smaller, thereby improving the atomization efficiency.

[0089] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments are not used as additional limitations on the content of the present application. The purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope of the description of the present application; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the present application.
