The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0043] FIG1 is a schematic diagram of an electronic atomization device provided in an embodiment of the present application.

[0044] As shown in FIG. 1 , the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20 .

[0045] 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 can be snap-connected, magnetically connected, etc.

[0046] In one example, the atomizer 10 and the power supply assembly 20 are not detachable, that is, they are integrally formed.

[0047] The atomizer 10 includes a sensor 11 and a liquid storage chamber A.

[0048] Liquid storage chamber A is used to store atomizable liquid matrix; the liquid matrix preferably comprises a tobacco-containing material, and the tobacco-containing material is included in the volatile tobacco flavor compounds released from the liquid matrix when heated. Alternatively or in addition, the liquid matrix can comprise a non-tobacco material. The liquid matrix can include water, ethanol or other solvents, plant extracts, nicotine solution and natural or artificial flavorings. Preferably, the liquid matrix further comprises an aerosol forming agent. The example of a suitable aerosol forming agent is glycerol and propylene glycol.

[0049] The susceptor 11 is configured to be able to be penetrated by a changing magnetic field and generate heat, so as to heat the liquid matrix from the liquid storage chamber A and generate an inhalable aerosol.

[0050] The susceptor 11 comprises a base body made of a magnetically conductive, non-conductive material and a conductive body bonded to at least a portion of the base body. The base body distorts or concentrates at least some of the magnetic field lines, thereby increasing the magnetic flux passing through the conductive body. This in turn increases eddy current losses in the conductive body, generating more heat. This improves the heating efficiency of the susceptor and enhances the user experience. Because the base body is made of a magnetically conductive, non-conductive material, the heat generated by eddy currents when the magnetic field penetrates is minimal.

[0051] A susceptor composed of a substrate made of a magnetically conductive, non-conductive material and a conductive material bonded to at least a portion of the substrate has a greater heating efficiency than a susceptor constructed solely of a conductive material. To better understand this application, the following verification and explanation are provided from different perspectives:

[0052] Before adopting this solution, as shown in the table below, a susceptor (whose heat generation can be caused by eddy currents and / or hysteresis losses) was placed in a spiral induction coil. In the mass column of the table, "Air" represents the spiral induction coil in an unloaded state, with no susceptor coupled to the induction coil. The coil has approximately 9 turns and a length of approximately 10 mm. The specific value represents the mass of the susceptor placed in the spiral induction coil for coupling. For example, "4 mg" represents a susceptor of 4 mg placed in the spiral induction coil for coupling. The conversion efficiency is calculated using the following formula: η = 1 - Rs(Air) / Rs(mg), where Rs(Air) represents the resonant resistance of the resonant circuit in an unloaded state, and Rs(mg) represents the resonant resistance of the resonant circuit in a loaded state, i.e., when the susceptor has a mass of 4 mg, the conversion efficiency η = 1 - 25.8 / 41.8 = 38.3%.

[0053] As can be seen from the table, the greater the mass of the susceptor, the greater its conversion efficiency η. However, this comes with the following problem: for the same amount of energy supplied to the susceptor, the greater the mass, the slower the temperature rises or falls. Reaching the target temperature requires more power to the susceptor, which reduces the battery life. During continuous puffs, the accumulated high temperature can affect the puff feel. Conversely, the smaller the mass of the susceptor, the smaller the space it occupies in the magnetic field, resulting in fewer magnetic lines of force passing through it, leading to a lower conversion efficiency η. This may result in a lower aerosol volume (TPM) produced by the susceptor heating the liquid matrix, or a lack of vaporization in the early stages of the puff. However, the smaller the mass of the susceptor, the faster the temperature rises or falls under the same energy supply, and the more concentrated the heat source. During continuous puffs, the accumulated high temperature will not affect the puff feel. 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.

[0054] Referring to the table above, taking a frequency f of 1.1 MHz as an example, the conversion efficiency η of a susceptor with a mass of 7.5 mg coupled to a magnetic field is 75.04%. The susceptor requires approximately 10 W of power consumption to raise the temperature of the liquid matrix to the required atomization temperature, such as 250°C, within 0.5 seconds. The power required by the heating component (susceptor + spiral induction coil) is approximately 10 W / 0.7504 = 13.33 W. 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%.

[0055] By adopting the following embodiment of the present application, the magnetic field is concentrated or distorted by the substrate, thereby increasing the magnetic flux passing through the conductor. The magnetic lines of force generated by the spiral induction coil can be more coupled to the conductor, thereby significantly improving the conversion efficiency η of the receptor. As a result, the power provided to the resonant circuit is also smaller, thereby improving the battery life. At the same time, in this embodiment, a smaller mass conductor can be used. 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 is not affected by the accumulated high temperature during continuous puffing.

[0056] Taking the data in the following table as an example, a conductor with a mass of 4 mg is combined with a substrate of about 10 mm to form a susceptor. The conversion efficiency η of the susceptor can be increased to 91.8%. In actual installation measurements, the temperature of the liquid matrix is ​​raised to the atomization temperature of 250°C within 0.5 seconds, with an input power of only 9.237 W (constant power output), and the TPM value is stable between 6 and 7. In some examples, the conductor can be bonded to the substrate by etching, coating, or 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 field line direction) and is separated from the two ends of the conductor by a certain distance; as a suitable example, the substrate is arranged to be surrounded by the conductor or the substrate surrounds the outer periphery of the local surface of the conductor. In other examples, the substrate can be in contact with the conductor or non-contact. For example, the substrate can be non-contact with the conductor, which is beneficial for reducing heat transfer from the conductor to the substrate and thus increasing the temperature rise rate of the conductor.

[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 improved heating efficiency, the conductor can be made smaller and lighter, which can not only help to concentrate the heat, but also reduce the power loss of the electronic atomization device 100 and improve the battery life.

[0060] Furthermore, since heat is concentrated in the conductor mounting area of ​​the substrate, other areas of the substrate receive less heat than the conductor mounting area. Therefore, the temperature differences between different areas of the substrate facilitate the atomization of different components in the liquid matrix, improving the user's puffing 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, heat generation in the conductor is caused solely by eddy currents. Of course, the conductor may also be magnetic, and heat may 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. Stainless steel is preferably used because stainless steel has a lower resistivity and allows a larger current to flow through it, 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 comprises a conductive track bonded to at least a portion of the substrate. The conductive track can be a conductive line extending along the substrate in a meandering pattern. Alternatively, it can be a mesh-like conductive grid. It is understood that it is also feasible for the conductor to be a continuous body bonded to at least a portion of the substrate; a continuous body means a body without a mesh-like structure.

[0066] Furthermore, at least a portion of the surface of the substrate may be coated with a second protective layer, which may be formed from glass, ceramic, or an inert metal. The second protective layer prevents the substrate from contacting the liquid matrix, thereby preventing harmful substances from 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 substrate have a higher magnetic permeability, 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, heat generation in the substrate (excluding heat transferred from the conductor to the substrate) is caused solely by hysteresis loss. When the Curie temperature of the substrate is reached, heat generation in the substrate completely stops.

[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 from the liquid reservoir A and transfer the absorbed liquid matrix to the conductor. For example, the substrate is configured as a porous structure, and the liquid matrix is ​​absorbed through the pores of the substrate and transferred to the conductor. In this case, the substrate integrates multiple functions, and the susceptor 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 susceptor 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-shaped 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 varying magnetic field under an alternating current. The magnetic field generator 21 includes a single induction coil or multiple induction coils. The induction coil or coils may have a shape that matches the shape of the susceptor. Similarly, the induction coil or coils conform to the shape of the housing of the aerosol generating device. For example, the induction coil or 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 circuit 22 to magnetic field generator 21 is between 500 kHz and 3 MHz. Preferably, the frequency is between 500 kHz and 2.5 MHz. More preferably, the frequency is between 500 kHz and 2 MHz. More preferably, the frequency is between 500 kHz and 1.5 MHz. More preferably, the frequency is between 500 kHz and 1 MHz. For example, the frequency of the alternating current supplied by circuit 22 to magnetic field generator 21 is 500 kHz, 600 kHz, 800 kHz, or 1.2 MHz.

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

[0081] FIG2 is a schematic diagram of a sensor provided in an embodiment of the present application.

[0082] As shown in FIG2 , the susceptor 11 includes a base 11a and a conductor 11b. The base 11a is constructed in a cylindrical structure. The conductor 11b is attached to the outer wall of the base 11a. The axial length of the conductor 11b is shorter than the axial length of the base 11a.

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

[0084] Figure 3 is a schematic diagram of another sensor provided by an embodiment of the present application. Different from the example in Figure 2, in the example in Figure 3, the conductor 11b is a discontinuous body and has meshes.

[0085] Fig. 4 is a schematic diagram of another sensor provided by an embodiment of the present application. Different from the example in Fig. 2, in the example in Fig. 4, the base 11a is constructed into a sheet or plate-like structure.

[0086] Figure 5 is a schematic diagram of another sensor provided by an embodiment of the present application. Unlike the example in Figure 4 , in the example in Figure 5 , the base 11a is configured such that the sides of the base 11a are generally arc-shaped along the direction extending from the upper end to the lower end of the base 11a. Both the upper and lower surfaces of the base 11a are continuous, meaning they are uninterrupted and free of slots or holes. The conductor 11b is bonded to the upper and / or lower surfaces of the base 11a and is positioned in the middle portion of the base 11a.

[0087] The width dimensions of the upper and lower ends of the base 11a are greater than the width dimension of the middle portion of the base 11a. Specifically, the width dimension of the upper end of the base 11a is d1, the width dimension of the middle portion of the base 11a is d2, and the width dimension of the lower end of the base 11a is d3, and both d1 and d3 are greater than d2. In a preferred embodiment, d1 and d3 are the same size. The size of d2 is between one-third and two-thirds of d1 (or d3), and preferably the 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 base 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, and 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 susceptor, thereby increasing the current density on the conductor 11b located in this part. When the susceptor is working, the current density in the middle part is greater than the current density at the two ends, so that the temperature rise rate in the middle part of the susceptor is greater than the temperature rise rate at the two ends. In this way, the heat generated by the susceptor is more concentrated, which is conducive to reducing the energy consumed to raise the temperature of the susceptor to the desired atomization temperature; on the other hand, this special shape of the substrate 11a can reduce the volume and mass of the conductor 11b, thereby reducing the energy required for the susceptor to reach the atomization temperature, 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 this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of this application. The purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive. In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of this application; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
