Description
Technical Field
The present invention belongs to the field of heating non-burning (Heat-Not-Burn, commonly known as HNB) aerosol generating devices.
Background
Heating a non-combustion aerosol-generating device (commonly referred to as an HNB smoking device or HNB smoking device) releases aerosol for user's consumption in a manner that heats but does not combust aerosol-generating material (also referred to as a smoking material), including but not limited to tobacco, tea, mugwort, herb etc. that releases a specific flavour, most typically tobacco. The aerosol-generating material may contain, in addition to its natural flavor component, additional flavors (various flavors such as menthol and rose essential oil), smoking agents (polyols such as glycerin and propylene glycol), and the like. The most popular heated non-combustible aerosol-generating articles currently are various cigarettes with tobacco as the smoking material and various herbal heated smoking products with non-tobacco herbs as the aerosol-generating material, both of which can be heated to produce aerosols of various specific flavours for consumption by the user.
The aerosol-generating article is typically heated by a heating appliance. The heating mode includes resistance heating and electromagnetic heating. The resistance heating is to insert a resistance heating sheet into an aerosol-generating article for heating, but the resistance heating sheet is easily bent or broken, and residue is easily dropped or left on the resistance heating sheet when the aerosol-generating article is pulled out after heating, and the residue is burnt to cause bad smell when the next heating is performed.
Electromagnetic heating solves the above problems, and instead of arranging a sheet-like susceptor in a heating appliance, the sheet-like susceptor is preset as a disposable consumable inside an aerosol-generating material section of an aerosol-generating article, so that the aerosol-generating article can be integrally inserted into/withdrawn from a receiving cavity of the heating appliance, and under the action of an alternating magnetic field generated by a coil surrounding the receiving cavity, the sheet-like susceptor electromagnetically induces heat, thereby heating surrounding aerosol-generating material to generate aerosol. By the mode, the risk of bending or breaking of the heating sheet is thoroughly eliminated, the process of inserting and extracting the heating sheet is omitted, slag is not dropped, and the heating sheet becomes a mainstream heating mode. The structure is adopted by the latest HNB product IQOS il ma electromagnetic heating smoking set which is developed by International Nicotiana giant PMI company 2021 in the next half year. In addition, many other HNB smoking set cigarette manufacturers at home and abroad also adopt the structure successively.
However, in practice it has been found that when sheet-like susceptors are used to heat segments of smoking material by internal electromagnetic induction, the amount of smoke is small, which is manifested by a low smoke volume and a low number of continuous suction ports, and certain user demands for large amounts of smoke cannot be met.
The present invention aims to solve the above-mentioned problems.
Disclosure of Invention
In one aspect the invention discloses an electromagnetic heating type aerosol-generating device with discrete arced susceptors, comprising a coil 11 and a receiving cavity 12 arranged inside the coil 11, the receiving cavity 12 being adapted to receive an aerosol-generating article 2 comprising axially arranged sheet susceptors 21, the key point being that a plurality of circumferentially discrete arced susceptors 13 are arranged on the inner wall of the receiving cavity 12.
Preferably, the cambered susceptor 13 is attached to the inner wall of the accommodating cavity 12 or embedded in the inner wall of the accommodating cavity 12.
Where susceptor means any substance capable of electromagnetic induction heating under alternating magnetic fields, typically ferromagnetic substances, such as magnetic ferrite, iron, steel, iron-containing alloys, etc., such as iron-nickel alloys, permalloy, stainless steel, etc.
Wherein the cambered surface refers to a part of a cylindrical surface, the cross section of the cambered surface is a section of continuous arc or discontinuous arc, and the arc refers to a part of a circumference. And allows the circumferential length of one part of the camber to be different from the axial length of the other part of the camber.
The central angle of the individual arc surface receptors is not limited and may be 1 ° to 180 °, preferably 10 ° to 150 °, more preferably 20 ° to 120 °, more preferably 30 ° to 90 °, and most preferably 45 ° to 60 °.
Preferably, the arced susceptor is provided in a plurality, for example 2, 4, 6, 8 or even more, in a circumferentially dispersed manner, preferably in a circumferentially uniformly dispersed manner, on the inner wall of the receiving chamber 2.
The cambered surface receptor is not limited in form and can be in various forms such as a continuous layer, a parallel grid, a net, scattered points and the like, so that the cambered surface can be a continuous cambered surface or a discontinuous cambered surface formed by a plurality of discrete lines or discrete points.
Preferably, the normal to the arced susceptor 7 is not parallel to the plane of the sheet-like susceptor 21 when the aerosol-generating article 2 is inserted into the receiving chamber 12, preferably perpendicular to the plane of the sheet-like susceptor 6, although it may be non-perpendicular, as long as it is non-parallel.
Preferably, the receiving cavity 12 is provided with a phase indicator 121 for indicating that the end face of the sheet-like susceptor 21 is located in a diametric direction indicated by the indicator when the aerosol-generating article is inserted into the receiving cavity 12, and that the diametric direction is not parallel to the normal of the arced susceptor 13.
Preferably, the aerosol-generating article comprises, in order from the distal lip end to the proximal lip end, an aerosol-generating material section, a support section, a cooling section and said filter section, all of which are wrapped by an outer wrapper, while the sheet-like susceptor 21 is placed inside the aerosol-generating material. Preferably, the aerosol-generating material is filled in the aerosol-generating material segments, the form of which is not limited, but is preferably sheet or parallel strip, wherein the support segments have intermediate gas flow channels, the cooling segments are filled with cooling material internally or the cooling segments are hollow tubes with side walls perforated with ventilation holes. The aerosol-generating article in which the aerosol-generating material section, the support section, the cooling section and the filter section are connected in sequence is a technology known in the HNB art and will not be described in detail. The aerosol-generating article in its simplest form may be provided with the support section, cooling section and filtering section all omitted, as these functional sections may be incorporated into the aerosol-heating apparatus as required. Of course, it is also possible to omit at least one of the support section, the cooling section and the filter section while leaving the remaining sections. The outer wrapper is at least used for wrapping the aerosol-generating material segments, and if other functional segments are present, other functional segments can also be wrapped at the same time. The outer wrapper must not be single-layered or multi-layered. The outer wrapping paper can be formed by rolling paper webs or can be a prefabricated paper tube.
Another aspect of the invention relates to a method of heating an aerosol-generating article 2 comprising axially arranged sheet-like susceptors 21 using the aforementioned electromagnetic heating type aerosol-generating device with discrete arced susceptors, by inserting the aerosol-generating article 2 into the receiving cavity 12 and electromagnetic induction heating in an alternating magnetic field provided by the coil, characterized in that the phase of insertion of the aerosol-generating article 2 is controlled such that the normal to the arced susceptor 13 is not parallel to the plane of the sheet-like susceptors 21, and then the electromagnetic induction heating of the arced susceptor 13 is used to supplement the heating effect-reduced region of the sheet-like susceptors 21 with aerosol-generating material. The control here may be a visual control by the user, but preferably the receiving chamber 12 is provided with a phase indicator 121 for indicating to the user that the exposed end surface of the sheet-like susceptor 21 inside the aerosol-generating article is located in a diametric direction indicated by the indicator when the aerosol-generating article is inserted into the receiving chamber 12, and the diametric direction is not parallel to the normal of the arced susceptor 13.
In the cross-section of the aerosol-generating segment, the sheet-like susceptor is typically located in a certain diametric direction. The effective temperature field refers to the temperature region: the temperature of which is not lower than the nine-component value of the predetermined heating temperature of the susceptor body and is greater than the heated release aerosol temperature of the aerosol-generating material. The region outside the effective temperature field is referred to as the heating effect attenuation region. For sheet receptors, the edges of the effective temperature field are typically ellipses with the major axis of the sheet receptor in the width direction, the major axis length of the ellipses typically being about 1.1-1.2 times the width of the sheet receptor, and the minor axis length of the ellipses typically being in the range of 1/5 to 2/3 of the major axis length, depending on the thickness of the sheet receptor. The dimensions of the sheet-like susceptor in the axial direction of the aerosol-generating article are herein referred to as the length, the longer dimension of the sheet-like susceptor in a cross-section perpendicular to the axial direction is referred to as the width, and the shorter dimension is referred to as the thickness.
The technical proposal can be freely combined on the premise of no contradiction.
The invention has the following beneficial effects:
1. the inventors have found in practice that the heating of the sheet susceptor from the interior of the smoking material is due to the fact that the heating of the sheet susceptor progressively weakens from the central axis of the smoking material to the outer periphery. Through practical tests by the inventors of the present invention, the effective temperature field of the sheet-like susceptor is not exactly circular but is approximately elliptical in cross-section of the segment of aerosol-generating material, as shown in fig. 3, wherein the dashed ellipse shows the boundary of the effective temperature field, in which the smoking material within the dashed ellipse can be effectively heated, is an effective heating zone, and beyond the dashed ellipse is a zone of reduced heating effect, the smoking material within this zone cannot be effectively heated, thereby resulting in wastage of smoking material and an insufficient amount of smoking. According to the invention, the plurality of circumferentially discrete arc-shaped receptors are additionally arranged in the accommodating cavity of the aerosol generating device, the heating effect weakening area is subjected to supplementary heating by virtue of electromagnetic induction heating, so that aerosol generating materials in the heating effect weakening area are fully utilized, the aerosol generating amount is increased, and the number of suction ports is prolonged.
2. In the prior art, a technical scheme of combining full circumferential heating of an integral circumferential susceptor with central heating of a sheet susceptor is adopted, but the technical scheme is not specially designed for the temperature field of the sheet susceptor, but circumferential heating is provided in an 'indiscriminate' way, so that the effective temperature field of the sheet susceptor is easy to overheat and electric energy is wasted. According to the invention, the cambered surface susceptor is arranged on the inner wall of the accommodating cavity, and only the heating effect weakening area of the flaky susceptor is subjected to accurate supplementary heating, so that overheating in an effective temperature field can not be caused, and electric energy is saved.

The cambered surface receptor is embedded in the inner wall of the accommodating cavity, and the exposed surface of the cambered surface receptor is flush with the inner wall surface of the accommodating cavity
Example 2
Substantially the same as in example 1, except that the number of arc-shaped susceptors is 4 and the central angle thereof is 30 °, as shown in fig. 4, in addition, the arc-shaped susceptors 4 are attached to the inner wall of the accommodating cavity 12, and since the arc-shaped susceptors 4 have a certain thickness more or less, after the aerosol-generating article 2 is inserted, a gap is left between the aerosol-generating article 2 and the inner wall of the accommodating cavity in the area where the arc-shaped susceptors 4 are not provided, so that air can flow through in the axial direction, and enter the interior of the aerosol-generating article from the end or waist of the aerosol-generating article 2 (if the waist has ventilation holes or the outer wrapping paper 5 of the aerosol-generating article is made of a breathable material), thereby performing the function of carrying the aerosol and/or cooling the aerosol.
