Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
The first embodiment is as follows: as shown in fig. 1 to 3, which are only one embodiment of the present invention, a dielectric heating aerosol-generating structure with a distribution plate comprises an aerosol-generating device 1 and an aerosol-generating article 2, wherein a working chamber 11 is arranged on the aerosol-generating device 1, the aerosol-generating article 2 comprises an aerosol-generating substrate 22, a susceptor 23 is arranged in the aerosol-generating substrate 22, a distribution plate 12 is arranged on a side wall of the working chamber 11, the distribution plate 12 comprises at least one anode plate 121 and at least one cathode plate 122, a power supply 13 electrically connected with the anode plate 121 and the cathode plate 122 and a controller 14 electrically connected with the power supply 13 are arranged in the aerosol-generating device 1, so that when the aerosol-generating substrate 22 is inserted into the working chamber 11, the controller 14 controls the power supply 13 to form alternating current to supply power to the anode plate 121 and the cathode plate 122, thereby creating an alternating electric field between the anode and cathode plates 121 and 122 that dielectrically heats the susceptor 23.
In the utility model, one end of the aerosol generating part 2 close to the aerosol generating substrate 22 is inserted into the working chamber 11 of the aerosol generating device 1, the anode plate 121 and the cathode plate 122 in the distributed electrode plate 12 in the working chamber 11 are respectively connected to the positive pole and the negative pole of the power supply 13, then the power supply 13 is controlled by the controller 14 to form alternating current, so that an alternating electric field is formed between the anode plate 121 and the cathode plate 122 to dielectrically heat the susceptor 23, an electric dipole in the susceptor medium rotates and vibrates violently along the electric field direction, and the friction between molecules generates heat, thereby heating the aerosol generating substrate 22 to generate aerosol; since the susceptor 23 is arranged in the aerosol-generating substrate 22, it corresponds to a uniform heating of the aerosol-generating substrate 22 from the inside.
In the present embodiment, the distributed electrode plate 12 includes at least one anode plate 121 and at least one cathode plate 122, generally, a plurality of anode plates 121 and cathode plates 122 are uniformly distributed on the inner wall of the working chamber 11, and one cathode plate 122 is disposed on both sides of any one of the anode plates 121, that is, the anode plate 121 and the cathode plate 122 are spaced apart from each other on the inner wall of the working chamber 11, so that the heating effect on the medium of the susceptor 23 is more uniform, and uniform heat distribution is further promoted.
In addition, the aerosol-generating article 2 comprises a filter 21 and a hollow acetate tube 24 disposed between the filter 21 and the aerosol-generating substrate 22, and the side wall of the aerosol-generating device 1 is provided with a through-hole 15 for communicating with the working chamber 11.
Thus, when a smoker draws air against the filter 21 of the polymeric material of the aerosol-generating article 2 to draw an airflow into the working chamber 11 via the through-holes 15, the airflow then flows into the mixture of aerosol-forming substrate, 22 and susceptor 23 media where an aerosol is formed and entrained in the airflow, and finally the airflow and aerosol flows through the hollow acetate tube 24 and the polymeric filter 21 for delivery to the mouth of the smoker.
In this embodiment, the controller 14 controls the power supply 13 to form the alternating current at a frequency of not less than 2 MHz. The frequency range of the high-frequency oscillation current can be 2MHz to 2.5GHz, a more conventional frequency of 2MHz to 300MHz can be selected, and an unconventional frequency of 500MHz to 1GHz can also be selected, so that a high-frequency oscillation electric field is formed between the anode plate 121 and the cathode plate 122, and the distributed polar plate 12 and the receptor 23 medium can be heated with high efficiency without establishing direct connection or electric connection.
The controller 14 may be a microprocessor, which may be a programmable microprocessor; the controller 14 may include other electronic components; the controller 14 may be configured to regulate the supply of power to the dielectric heater; power may be supplied to the dielectric heater continuously after activation of the device, or may be supplied intermittently, such as on a puff-by-puff basis; power may be supplied to the dielectric heater in the form of current pulses.
The power source 13 may be a battery; alternatively, the power supply 13 may be another form of charge storage device, such as a capacitor; the power source 13 may also require recharging and may have a capacity that allows sufficient energy to be stored for one or more puffs; for example, the power supply 13 may have sufficient capacity to allow continuous aerosol generation for a period of about six minutes or a multiple of six minutes. Even the power supply 13 may have sufficient capacity to allow a predetermined number of puffs or discrete activations of the induction heater.
The dielectric heating aerosol generating structure with the distributed polar plates is simple in structure, the resistance heating mode is replaced by the dielectric heating mode, the inside and the outside of the whole aerosol generating base material can be effectively heated to generate aerosol, and the polar plates arranged in a distributed mode can further promote uniform heat distribution in the dielectric heating process.
Second embodiment, as shown in fig. 1 to 3, is only one embodiment of the present invention, and based on the first embodiment, in the dielectric heating aerosol-generating structure with a distribution plate of the present invention, a wrapping layer is disposed on the outer side of the aerosol-generating article 2, and the wrapping layer may be a soft member, which can prevent the outer side of the aerosol-generating article 2 from being damaged by friction with the distribution plate 12.
Furthermore, the aerosol-generating device 1 side wall is provided with a switch 16 electrically connected to the controller 14. The induction heater can be activated by pressing the switch 16 when the user sucks on.
In this embodiment, a "susceptor" is essentially a susceptor medium, meaning a substance that heats up when subjected to a changing electric field, which can cause the electric dipoles in the susceptor 23 medium to oscillate in a vigorous rotational motion in the direction of the electric field, resulting in the friction of the molecules against each other, producing heat. During use, the susceptor 23 medium is located in the working chamber 11 of the aerosol-generating device 1 physically composited with the aerosol-generating substrate 22. In this way, the aerosol-generating substrate 22 is heated by the dielectric during use so that an aerosol is formed for smoking.
Of course, the susceptor medium may be solid, hollow, or porous; the susceptor medium may be any of a solid, a liquid, and a mixture of solids and liquids.
That is, the susceptor 23 medium may be formed of any material capable of being dielectrically heated to a temperature sufficient to aerosolize the aerosol-generating substrate 22, suitable materials for the susceptor 23 medium include water, alcohols, metal oxides, and various inorganic salts, such as barium dioxide and ferrite, among others. Alternatively, the susceptor medium may be selected to be water or alcohol, which may be heated to temperatures up to or exceeding 250 degrees celsius.
Even more, the susceptor 23 is a particle ball with several surfaces provided with openings. When the susceptor 23 medium is solid particles, each solid particle may have a particle size in the range of 10 microns to 200 microns (further alternatively 15 microns to about 100 microns, and most preferably 15 microns to 25 microns), and 10 to 1000 micropores may be disposed on each particle, each micropore having a pore size in the range of 10 nanometers to 10 microns.
Finally, the housing of the aerosol-generating device 1 may be made of a non-polar material, such that no dielectric losses are created in the housing. In other words, the shell may be made of a non-susceptor dielectric material (e.g., a non-susceptor material that is non-polar). Also, the portion between the case 1 and the distribution plate 12 may be made of a non-polar material.
Third embodiment, as shown in fig. 3 to 5, which is only one embodiment of the present invention, on the basis of any of the above embodiments, in the dielectric heating aerosol generating structure with a distribution plate of the present invention, the distribution plate 12 is a solid sheet-shaped heating plate, which is uniformly arranged along the axial direction and the circumferential direction of the working chamber 11 on the inner side surface of the working chamber 11, and is configured to envelop the aerosol generating part 2 in the working chamber 11.
Here, the distribution plate 12 is formed of a plurality of plate arrays, and the distribution plate 12 is arranged around at least a portion of the working chamber 11 and has a solid plate structure. And the distribution plate 12 may have any suitable cross-section. For example, the individual plates of the distributed plate 12 may each have a square, oval, rectangular, triangular, pentagonal, hexagonal, or similar cross-sectional shape.
Of course, the distribution plate 12 has at least one pair (the anode plate 121 and the cathode plate 122), and may have any number of pairs greater than two, but at least one of the anode plate 121 and the cathode plate 122 is ensured, and it should be noted that the number of the cathode and the anode is not necessarily the same.
In one case, the anode plate 121 and the cathode plate 122 are both long strip-shaped pieces, and the extending directions of the anode plate 121 and the cathode plate 122 are both parallel to the axial lead of the working chamber 11, as shown in fig. 3;
in another case, the distributed plate 12 includes a plurality of plate layers, each plate layer includes a plurality of anode plates 121 and cathode plates 122 alternately arranged, and each plate layer forms a circular ring arranged inside the working chamber 11, as shown in fig. 4, such that the anode plates 121 and the cathode plates 122 are arranged in an interlaced array at the periphery of the aerosol-generating article 2, and each anode plate 121 has 4 cathode plates 122 and 4 anode plates 121 at the periphery, so as to make the electric field intensity at the medium of the susceptor 23 more uniform;
in yet another case, much the same as FIG. 4, but with the only difference that the plates of different plate layers may be offset by a distance of about half the plate width, as shown in FIG. 5; the electric field strength at the medium of the susceptor 23 can likewise be made more uniform.
The dielectric heating aerosol generating structure with the distributed polar plates is simple in structure, the resistance heating mode is replaced by the dielectric heating mode, the inside and the outside of the whole aerosol generating base material can be effectively heated to generate aerosol, and the polar plates arranged in a distributed mode can further promote uniform heat distribution in the dielectric heating process.

Any modifications, equivalents, improvements and the like made to the above embodiments in accordance with the technical spirit of the present invention should be included in the scope of the present invention.
