Description

Electromagnetic induction type aerosol generating unit and aerosol generating product comprising same

Technical Field

The utility model relates to the technical field of low-temperature heating non-combustion product production, in particular to an electromagnetic induction type aerosol generating unit and an aerosol generating product comprising the same.

Background

Electromagnetic induction heating cigarettes are now the focus of research, whereas some researchers in the prior art have placed susceptors into aerosol-generating units of aerosol-generating articles, the shape of which is largely divided into three types:

the first is a strip or needle of electromagnetic induction material, similar to a heater pin or sheet in a center-heated resistance-heated cigarette smoking set. For example, CN106255429a discloses an aerosol-generating article comprising a plurality of elements assembled in the form of a strip having a mouth end (70) and a distal end upstream of the mouth end. The plurality of elements comprises an aerosol-forming substrate at or towards the distal end of the strip. An elongated susceptor is arranged substantially longitudinally inside the strip and in thermal contact with the aerosol-forming substrate (20). The susceptor enables the article to be consumed using an electrically operated aerosol-generating device having an inductor. The problem with this is that the susceptor extends only axially along the aerosol-generating unit and is unevenly heated, the temperature of the smoking material close to the susceptor being high and the degree of heating of the smoking material further from the susceptor being low.

And the second is to directly wrap a layer of electromagnetic induction material outside the smoke generating material, which is similar to a circumferential heating cylinder in a circumferential heating type resistance heating cigarette smoking set. For example, CN112369716a is a heated non-combustible cigarette and method of making. The heating non-burning cigarette comprises a smoke section and a filter tip which are arranged along the length direction of the cigarette, wherein the smoke section comprises columnar smoke materials and a composite heating layer surrounding the side surface of the smoke materials; the composite heating layer comprises an inner high infrared emissivity material layer and an outer electromagnetic induction layer, wherein the electromagnetic induction layer can induce an alternating electromagnetic field to generate heat, and heat generated by the electromagnetic induction layer can excite the high infrared emissivity material layer to emit infrared rays. The susceptor suffers from similar problems to the previous one, as well as from uneven heating, except that the central smoking material is heated to a low degree. In order to solve the above two problems, some studies have conceived that the susceptor is provided as a plurality of rods or sheets, but the plurality of susceptors are not connected to each other by dispersion, resulting in uneven heating, insufficient fragrance release, and the like.

The third is to directly add granular electromagnetic induction material into fuming material, which has the problems that granular electromagnetic induction material is easy to sink during preparation process, granular electromagnetic induction material is unevenly distributed, granular electromagnetic induction material is scattered and discontinuous, and the two points can also lead to uneven heating of the susceptor.

In conclusion, the susceptor and the fuming section in the prior art have fewer contact points, and the contact points cannot be connected with each other, so that the problems of uneven heating, insufficient fragrance release and the like are caused.

The present utility model has been made to solve the above-mentioned problems.

When the aerosol-generating article is used for oxygen-deficient heating, gas is not allowed to enter the aerosol-generating substrate through the closure 5, and the vent holes 41 are allowed to enter, when the closure 5 is gas-permeable, the aerosol-generating device is provided with a seal at the contact point with the closure 5 after the aerosol-generating article is inserted into the aerosol-generating device, so that the closure 5 is sealed to ensure that air cannot enter the aerosol-generating unit 1 through the closure 5; when the closure 5 is air impermeable, air cannot enter the aerosol-generating unit 1 through the closure 5. The aerosol-generating article may be inserted into the aerosol-generating device without a seal at a contact point with the sealing member 5, but may be provided with a seal.

The vent holes 41 may be pre-perforated before the outer tube 11 is filled in each segment, or may be perforated after filling is completed. Preferably, the outer layer of the outer tube 11 is further wrapped with a label paper for the purpose of aesthetic appearance and preventing the aerosol-generating material in the outer tube 11 from leaking out of the paper tube. If the outer tube 11 is pre-perforated, it is preferable to make perforations after wrapping the label paper around the outer tube 11, and the perforation requires perforating both the label paper and the outer tube 11 to introduce ambient air into the aerosol-generating article.

Compared with the prior art, the utility model has the following beneficial effects:

1. the susceptor 13 of the present utility model extends in a plurality of directions with different portions facing different positions of the aerosol-generating material 12, and the plurality of directions can be used to ensure that the susceptor 13 and the aerosol-generating material 12 have more contact space and contact points, so as to accelerate the preheating speed of the smoking article, make the heating more uniform, and make the fragrance release more complete.

2. The susceptor 13 is integrated, can be in a spring shape, a disordered and agglomerated steel wire ball shape, a folded wire shape and a vertical clothes hanger shape, and can ensure that the contact point of the integrated susceptor and the aerosol generating material 12 is continuous, thereby being more beneficial to uniform heating.

3. The susceptor 13 of the present utility model extends in a plurality of directions and is not fixed in orientation and shape, and the contact area of the susceptor 13 with the aerosol generating material can be varied by controlling the quality assurance of the susceptor 13.

4. In a preferred embodiment of the utility model, the smoking article is in the form of particles, gel, powder, etc. which can better cooperate with the susceptor of the utility model to achieve interconnection between points of contact;

5. the contact area between the susceptor 13 and the aerosol generating material 12 is far larger than that of the susceptor in the prior art, so that the preheating time can be remarkably reduced, the heating temperature can be increased, and the aroma substances in the smoking articles can be fully released.

6. The sealing piece 5 of the aerosol generating product can be completely airtight, the corresponding outer tube 11 is provided with the vent hole 41 penetrating through the outer tube 11, and the sealing piece can be matched with a smoking set without air flow, when no air in the aerosol generating unit passes through a smoking material, the inside of the aerosol generating unit is in an oxygen-deficient state, and under the condition, the heating temperature is higher than 300 ℃, combustion can still not be generated, and the higher heating temperature is favorable for fully realizing aroma release and improving the aroma quantity. Because air cannot enter the aerosol generating unit 1 through the sealing member 5 in the heating process, the inside of the aerosol generating unit 1 is in an oxygen-deficient state, and combustion cannot be generated even if the temperature reaches 300 ℃ or higher, so that the aerosol generating unit 1 can be heated to a higher temperature, the concentration of generated aerosol is high, the air is introduced into the vent holes 41 at the functional section 4, and the air is converged at the functional section 4, so that the air has an extraction effect on the aerosol generated by the aerosol generating unit 1, and the concentration of smoke can be ensured. In addition, when the heating temperature is higher than 300 ℃, combustion can still not be generated, and the higher heating temperature is favorable for fully realizing fragrance release and improving the fragrance quantity. The heat loss is small, the heating efficiency is higher, and the sensory evaluation is better.
