The first embodiment is as follows: as shown in fig. 1 to 4, which are but one embodiment of the present invention, a dielectrically heated aerosol-generating structure having a comb plate comprises an aerosol-generating article 2 and an aerosol-generating device 1, the aerosol-generating article 2 comprising an aerosol-generating substrate 22, a filter 21 and a hollow acetate tube 24 disposed between the filter 21 and the aerosol-generating substrate 22, a susceptor 23 disposed in the aerosol-generating substrate 22, a working chamber 11 disposed on the aerosol-generating device 1 for facilitating insertion of the aerosol-generating substrate 22, a comb plate 12 disposed in the working chamber 11, a power supply 13 for supplying power to the comb plate 12 and a controller 14 for controlling the power supply 13 to form an alternating current, such 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 power the comb plate 12, so that an alternating electric field is formed at the comb plate 12 to dielectrically heat the susceptor 23.
The comb plate 12 includes a first main rod 123, a second main rod 124, an anode plate 121 connected to the first main rod 124, and a cathode plate 122 connected to the second main rod 124, wherein the anode plate 121 and the cathode plate 122 are respectively connected to the positive and negative poles of the power supply 13 (actually, the anode plate 121 is connected to the positive pole of the power supply 13 through the first main rod 123, and the cathode plate 122 is connected to the negative pole of the power supply 13 through the second main rod 124), and the anode plate 121 and the cathode plate 122 are arranged in parallel.
In the invention, one end of the aerosol-generating article 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 comb-type polar 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 among 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, at least one anode plate 121 and at least one cathode plate 122 in the comb-type polar plate 12, generally speaking, a plurality of anode plates 121 and cathode plates 122 are uniformly distributed on the inner wall of the working chamber 11, and at least one cathode plate 122 is arranged between two adjacent anode plates 121, that is, the anode plates 121 and the cathode plates 122 are arranged on the inner wall of the working chamber 11 at intervals, so that the heating effect on the medium of the susceptor 23 is more uniform, and uniform heat distribution is further promoted.
Here, the first main rod 123 and the second main rod 124 extend along the axial direction of the working chamber 11 and are disposed on the inner side wall of the working chamber 11, the anode plate 121 and the cathode plate 122 extend along the circumferential direction of the working chamber 11 and are disposed on the inner side wall of the working chamber 11, and an envelope space for facilitating the insertion of the aerosol generating substrate 22 is formed between the anode plate 121 and the cathode plate 122.
Moreover, the diameter of the envelope space enclosed between the anode plate 121 and the cathode plate 122 near the open end of the working chamber 11 is not smaller than the diameter of the envelope space enclosed between the anode plate 121 and the cathode plate 122 near the bottom end of the working chamber 11. This may provide a tapered cross-sectional area for the working chamber 11, which may facilitate insertion of the aerosol-generating article 2 between the anode plate 121 and the cathode plate 122.
Of course, the working chamber 11 is provided with the protruding portions 111 extending to between the anode plate 121 and the cathode plate 122, and actually, each anode plate 121 or cathode plate 122 is located between two adjacent protruding portions 111, and the protruding portions 111 can limit the position of the anode plate 121 and the cathode plate 12, and can prevent the anode plate 121 and the cathode plate 12 from directly contacting to cause a short circuit of the power supply 13.
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, the more conventional frequency of 2MHz to 300MHz can be selected, and the 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 comb-type polar plate 12 and the receptor 23 can carry out high-efficiency heating 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 comb-type polar plate is simple in structure, the dielectric heating mode is adopted to replace a resistance heating mode, the inside and the outside of the whole aerosol generating base material can be effectively heated to generate aerosol, the comb-type polar plate can further guide an aerosol generating part to be inserted and clamped, the heating efficiency is high, and meanwhile, uniform heat distribution in the dielectric heating process can be promoted.
In the second embodiment, as shown in fig. 1 to 4, which is only one embodiment of the present invention, based on the first embodiment, in the dielectric heating aerosol-generating structure with a comb 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 comb 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 may be activated by pressing the switch 16 when the user sucks.
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 an alcohol, which may be heated to a temperature at or above 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.
And suitable materials for the comb plate 12 include graphite, molybdenum, silicon carbide, stainless steel, niobium, and aluminum. Preferably, the comb plate 12 is a metal member.
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).
