[0002] The present application relates to the field of tobacco technology, and in particular to an aerosol generating product. Background Art

[0003] In the heated cigarette market, aerosol-generating products include an aerosol-generating matrix, which produces inhalable aerosol smoke when heated. Heating tobacco-containing aerosol-generating matrices to produce aerosol smoke is well known in the art.

Existing heated cigarette aerosol-generating products use built-in heating receptors to heat the aerosol-generating matrix. However, during actual product puffing, it was found that portions of the aerosol-generating matrix away from the receptors remained insufficiently heated, resulting in insufficient heating of the aerosol-generating matrix and insufficient smoke production.

[0027] This embodiment is written in a progressive manner.

[0028] Referring to FIG1 , the present application provides an aerosol-generating article, comprising:

[0029] An aerosol generating matrix strip segment and a heat supplementing layer wrapped around the periphery of the aerosol generating matrix strip segment.

[0030] In the above scheme, a wrapping heating layer is provided on the periphery of the aerosol generating matrix strip segment. When the aerosol generating matrix strip segment is in the electromagnetic heating mode, the heating layer protects the heat while the heat is fully supplied to the aerosol matrix away from the receptor, thereby achieving full utilization of the heat of the aerosol generating matrix and generating sufficient aerosol smoke to enhance the satisfaction of smoking.

[0031] As an optional embodiment, the heat-compensating layer is a metal or alloy layer, and the thermal conductivity of the heat-compensating layer is 100-450W / m·K; the heat-compensating layer adopts an aluminum foil layer or a copper foil layer, and preferably adopts an aluminum and aluminum alloy heat-compensating layer with a thermal conductivity of 150-350W / m·K. The aerosol-generating matrix segment is matched with an aluminum foil or copper foil rolling paper and an electromagnetic heating sensor, which forms a higher aerosol-generating matrix utilization rate under the electromagnetic heating state, thereby improving the smoking experience. Furthermore, a texture structure is added to the heat-compensating layer on the side close to the outer periphery of the aerosol-generating matrix segment, and the texture structure is preferably embedded in the outer periphery of the aerosol-generating matrix segment. The additional texture increases the friction of the aerosol-generating matrix segment during the tobacco rod rolling process, while obtaining a better heat-compensating effect.

[0032] As an optional implementation manner, the thickness of the heat supplement layer is 3-50 μm; that is, the thickness of the aluminum foil layer or copper foil layer paper is 3-50 μm.

[0033] In a preferred embodiment, the aerosol-generating article includes a susceptor longitudinally disposed within an aerosol-generating matrix strip; the susceptor is configured to generate heat to heat the aerosol-generating matrix strip. The susceptor is an electromagnetic heating plate susceptor, which cooperates with an electromagnetic heating device to generate heat to heat the aerosol-generating matrix strip and produce aerosol (smoke). It should be noted that the electromagnetic heating technology used in the electromagnetic heating plate susceptor is based on prior art.

[0034] Preferably, the susceptor is a sheet-like structure; the shape of the susceptor is one of a straight shape, an M shape, a V shape, a W shape, an S shape, a Y shape, a sine shape and a cosine shape.

[0035] The sheet-shaped susceptor is arranged on the central axis of the aerosol-generating substrate segment and extends from one end to the other end of the aerosol-generating substrate segment.

[0036] Compared with the straight-line shaped sheet-like receptor, the sheet-like receptors in other shapes increase the contact and heating area with the aerosol generating matrix segments, thereby improving the heating effect of the aerosol generating matrix.

[0037] Furthermore, the thickness of the susceptor is 0.03-0.05 mm; the width of the susceptor is 2-6 mm.

[0038] As an optional embodiment, the aerosol generating product of the present application further includes: a cigarette paper layer wrapped around the outer periphery of the heat supplementary layer, so that the aerosol generating product has the same appearance as the existing aerosol generating product.

[0039] As an optional embodiment, the aerosol generating product of the present application further comprises: a filter mouthpiece segment connected to one end of the aerosol generating substrate segment; the filter mouthpiece segment is used for suction and filtration of smoke and may be an existing tow filter mouthpiece segment.

[0040] Preferably, the filter cigarette holder rod segment comprises a supporting segment, a cooling segment and a filtering segment connected in sequence; the supporting segment is connected to one end of the aerosol generating matrix strip segment, and the filtering segment is a stuffing tow filtering segment.

[0041] In addition, by conducting the same test comparison with the aerosol-generating product in which the aerosol-generating substrate is directly wrapped in the existing cigarette paper layer, the following control data are obtained:

[0042] Data on the content of main components of smoke in aerosol-generating products:

[0043] It can be seen from the data in the above table that the content of smoke components generated by the aerosol generating product with an aluminum foil layer and a heating layer of the present application is effectively improved.

[0044] Data on smoke concentrations in aerosol-generating products:

[0045] It should be noted that in the smoke concentration data, the number of test cigarettes was five, the number of test puffs was eight, and the test data of the five cigarettes were averaged to obtain the smoke concentration of each puff; from the above data graph, it can be seen that the aerosol-generating product with an aluminum foil layer and a heating paper winding layer of the present application generates a more stable and abundant smoke concentration when heated and puffed, effectively reducing the problem of reduced smoke concentration during subsequent puffing of the aerosol-generating product.

[0046] It should be noted that while this application does not describe an exhaustive description of the prior art, the above description of the disclosed embodiments is provided to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to be embodied in the widest possible manner consistent with the principles and novel features disclosed herein.
