Abstract

The application relates to an aerosol generating article, comprising: a substrate section, comprising a substrate body and a first cladding layer cladded on the substrate body in the circumferential direction; a confluence filter section connected to one end of the substrate section in the axial direction, used for filtering the airflow flowing out of the substrate section; wherein the first cladding layer is provided with a substrate section air inlet hole communicating the inner and outer surfaces thereof, and the distance between the substrate section air inlet hole and the end face of the substrate section connecting the confluence filter section is greater than 0 mm and less than 1 mm. The aerosol generating article can effectively increase the air inlet amount and the total ventilation rate of the sub-confluence section by providing the substrate section air inlet hole at a position where the distance between the first cladding layer and the end face of the substrate section connecting the confluence filter section is less than 1 mm.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to an aerosol generating article. BACKGROUND

[0002] An aerosol is a colloidal dispersion system formed by dispersing and suspending small particles of solid or liquid in a gaseous medium. Since the aerosol can be absorbed by the human body through the respiratory system, it provides a new type of alternative absorption method for users. An atomizer is a device that forms an aerosol by heating or ultrasonic means from a stored atomizable substrate. The atomizable substrate includes nicotine-containing e-liquid, medical drugs, and skin care lotion. Atomizing these media can deliver an inhalable aerosol to users, replacing conventional product forms and absorption methods.

[0003] A heat-not-burn atomized substrate is a new type of atomized substrate that uses a special heat source and substrate to heat (the heating temperature is below 500°C or even lower). During heating, various substances in the atomized substrate produce an aerosol by volatilization to meet the needs of smokers. The heat-not-burn atomized substrate does not produce open flames and ash during the smoking process, is more environmentally friendly, can provide a good user experience for users, and reduces the harmful substances produced by the high-temperature cracking of conventional atomized substrates during combustion, thereby reducing the physical harm to users.

[0004] However, due to the structural defects of the atomizer, part of the aerosol generated by the existing heat-not-burn atomized substrate cannot smoothly flow out following the airflow, so that the effective substances of the heat-not-burn atomized substrate, such as nicotine, cannot be well precipitated, thereby affecting the further improvement of the user experience. SUMMARY

[0005] Therefore, it is necessary to provide an aerosol generating article to solve the problem that the aerosol cannot smoothly flow out, and the aerosol generating article can achieve the technical effect of making the aerosol smoothly flow out.

[0006] According to an aspect of the present application, an aerosol generating article is provided, comprising:

[0007] a substrate section including a substrate body and a substrate section cladding layer cladded on the substrate body in a circumferential direction;

[0008] a converging filter section connected to one end of the substrate section in an axial direction, for filtering the airflow flowing out of the substrate section;

[0009] wherein the substrate section cladding layer is provided with a substrate section air inlet hole communicating the inner and outer surfaces thereof, and the distance between the substrate section air inlet hole and the end face of the substrate section connecting the converging filter section is greater than 0 mm and less than 1 mm.

[0010] In one of the embodiments, the matrix segment cover layer is provided with a plurality of matrix segment air holes, and all the matrix segment air holes are arranged at intervals along the circumference of the matrix segment.

[0011] In one of the embodiments, all the matrix segment air holes are arranged at non-equidistant intervals along the circumference of the matrix segment.

[0012] In one of the embodiments, the number of the matrix segment air holes is 2-20.

[0013] In one of the embodiments, the confluence filter segment comprises:

[0014] a sub-confluence segment connected to one end of the matrix segment in the axial direction and having a cavity for air flow to pass through; and

[0015] a sub-filter segment connected to the end of the sub-confluence segment away from the matrix segment and used for filtering the air flow out of the cavity.

[0016] In one of the embodiments, the sub-confluence segment is provided with at least one group of sub-confluence segment air holes, and each group of the sub-confluence segment air holes communicates the cavity with the external environment.

[0017] In one of the embodiments, the distance between each group of the sub-confluence segment air holes and the sub-filter segment is 1-10 mm.

[0018] In one of the embodiments, the sub-confluence segment is provided with a plurality of groups of the sub-confluence segment air holes, each group of the sub-confluence segment air holes is arranged at intervals along the axial direction of the sub-confluence segment, each group of the sub-confluence segment air holes comprises a plurality of the sub-confluence segment air holes, and all the sub-confluence segment air holes in the same group are arranged at intervals along the circumference of the sub-confluence segment.

[0019] In one of the embodiments, all the sub-confluence segment air holes in the same group are arranged at equidistant intervals along the circumference of the sub-confluence segment.

[0020] In one of the embodiments, the number of each group of the sub-confluence segment air holes is 2-20.

[0021] The aerosol generating article can effectively increase the air intake amount and total ventilation rate of the sub-converging section by opening the substrate section air intake hole at a position less than 1 mm from the end face of the first cladding layer relative to the connection of the converging filter section. When the user generates negative pressure at the end face of the aerosol generating article away from the substrate section by suction, it is easier to gradually bring out the nicotine and flavor substances generated by the substrate body during the heating process, thereby having better suction consistency and effectively improving the user's experience. Moreover, since the opening position of the substrate section air intake hole is very close to the end face of the substrate section, the air flow through the substrate body can be minimized, thereby maximizing the negative pressure and oxygen-poor state of the substrate body, better releasing the effective substances in the aerosol forming substrate, and ensuring that the temperature of the substrate body is relatively stable during the dynamic process of suction, so that the release amount of the aerosol remains consistent.

[0034] Referring to Figure 1 and Figure 2 , Figure 1 a schematic view of an aerosol generating article in an embodiment of the present application is shown; Figure 2 a schematic view of an internal structure of an aerosol generating article in an embodiment of the present application is shown.

[0035] An aerosol generating article 100 in an embodiment of the present application is in a cylindrical structure with a circular cross section. The aerosol generating article 100 can be inserted into a heating air passage of an atomizing device, and the atomizing device can heat the aerosol generating article 100 to generate aerosol for a user to smoke.

[0036] The aerosol generating article 100 is in a cylindrical structure as a whole, and the aerosol generating article 100 has a circular cross section. The aerosol generating article 100 includes a substrate segment 120 and a confluence filter segment 140 connected to each other, and the confluence filter segment 140 is connected to an axial end of the substrate segment 120. The substrate segment 120 can generate aerosol under heating of the atomizing device, and the aerosol flows out of the aerosol generating article 100 after being filtered by the confluence filter segment 140 for a user to smoke. It can be understood that the shape and size of the aerosol generating article 100 are not limited, and the cross section of the aerosol generating article 100 can also be in a regular or irregular shape such as an elliptical shape or a rectangular shape.

[0037] The substrate segment 120 includes a substrate body 121 and a substrate segment cladding layer. The substrate segment cladding layer is cladded on the substrate body 121 to form a cylindrical structure, and an outer surface of the substrate segment cladding layer forms an outer cylindrical surface of the cylindrical structure. The shape of the cross section perpendicular to the axial direction of the cylindrical structure can be circular. It can be understood that the shape of the cross section of the cylindrical structure is not limited to this, and in some other embodiments, the shape of the cross section of the cylindrical structure can also be a regular or irregular shape such as an elliptical shape or a rectangular shape.

[0038] Further, the substrate body 121 can include tobacco filler, which can be in the form of filaments, granules, sheets, or other regular or irregular shapes. It can be understood that the material forming the substrate body 121 is not limited, and the substrate body 121 can be formed of a single material or a plurality of materials mixed in different proportions, and other substances can also be added to the substrate body 121, so as to generate aerosols with different compositions and flavors to meet the different needs of users. The substrate segment cover layer can be formed of a wrapping material such as cigarette paper, so as to maintain the shape of the substrate body 121. It can be understood that the material forming the substrate segment cover layer is not limited thereto, and in other embodiments, the substrate segment cover layer can also be formed of other materials such as aluminum foil to meet different requirements.

[0039] Please continue to refer to Figure 1 and Figure 2 The confluence filter segment 140 includes a sub-confluence segment 141 and a sub-filter segment 143. The sub-confluence segment 141 is connected to one axial end of the substrate segment 120, and the sub-filter segment 143 is connected to the other axial end of the sub-confluence segment 141 away from the substrate segment 120. In this way, the aerosol generated after the substrate segment 120 is heated can flow out after confluence in the sub-confluence segment 141 and filtration in the sub-filter segment 143.

[0040] In some embodiments, the sub-confluence segment 141 includes a hollow tube 1412 and a sub-confluence segment cover layer. The hollow tube 1412 is a hollow tubular structure with both ends open, and the sub-confluence segment cover layer can be formed of a wrapping material such as formed paper. The sub-confluence segment cover layer is wrapped around the outer circumferential surface of the hollow tube 1412 in the circumferential direction to form an integral whole. In this way, the sub-confluence segment 141 forms a cavity 1414a that is connected to the substrate segment 120. The aerosol flowing out of the substrate segment 120 enters the cavity 1414a and confluences with the airflow in the cavity 1414a, and then flows into the confluence filter segment 140 under the entrainment of the airflow. It can be understood that the shape and structure of the sub-confluence segment 141 are not limited, and the cross section of the sub-confluence segment 141 can be a circular ring, a square frame, or other regular or irregular shapes. The materials forming the hollow tube 1412 and the sub-confluence segment cover layer can also be set as needed to meet different requirements.

[0041] In some embodiments, the sub-filter segment 143 includes a filter medium 1432 and a sub-filter segment cover layer. The sub-filter segment cover layer is wrapped around the filter medium 1432 to form a columnar structure, and the outer surface of the sub-filter segment cover layer forms the outer circumferential surface of the columnar structure. The shape of the cross section of the columnar structure perpendicular to the axial direction can be circular. It can be understood that the shape of the cross section of the aforementioned columnar structure is not limited thereto, and in other embodiments, it can also be an ellipse, a rectangle, or other regular or irregular shapes.

[0042] The filter medium 1432 is formed of a high-molecular filler material that can filter and cool aerosol flowing therethrough, and the sub-filter segment covering layer can be formed of a wrapping material such as a plug wrap. It can be understood that the material forming the filter medium 1432 and the material forming the sub-filter segment covering layer are not limited, and in other embodiments, the filter medium 1432 and the sub-filter segment covering layer can be formed of other materials to meet different filtration requirements.

[0043] Further, the aerosol generating article 100 further includes a confluence filter segment covering layer and a connecting layer. The confluence filter segment covering layer is formed of a plug wrap or other wrapping material, and the confluence filter segment covering layer is wrapped around the outer surfaces of the sub-confluence segment covering layer and the sub-filter segment covering layer to form a complete confluence filter segment 140. The connecting layer is formed of a tipping paper or other wrapping material, and the connecting layer is wrapped around one end of the confluence filter segment covering layer close to the substrate segment 120 and one end of the substrate segment covering layer close to the sub-confluence segment 141 to form a complete aerosol generating article 100. It can be understood that the materials forming the confluence filter segment covering layer and the connecting layer are not limited and can be set as needed to meet different requirements.

[0044] In this way, the substrate segment 120 includes a substrate body 121 and a first covering layer 123 wrapped around the substrate body 121 in the circumferential direction, where the first covering layer 123 is formed by layering a substrate segment covering layer wrapped around the substrate body 121 and a connecting layer wrapped around one end of the substrate segment covering layer close to the sub-confluence segment 141. The sub-confluence segment 141 includes a hollow tube 1412 and a second covering layer 1414 wrapped around the outer circumferential surface of the hollow tube 1412 in the circumferential direction, where the second covering layer 1414 is formed by layering a sub-confluence segment covering layer wrapped around the hollow tube 1412 and a confluence filter segment covering layer wrapped around the sub-confluence segment covering layer. The sub-filter segment 143 includes a filter medium 1432 and a third covering layer 1434 wrapped around the filter medium 1432 in the circumferential direction, where the third covering layer 1434 is formed by layering a sub-filter segment covering layer wrapped around the filter medium 1432 and a filter end covering layer wrapped around the sub-filter segment covering layer.

[0045] The first covering layer 123 is defined as the general term for the layered structure wrapped around the substrate body 121, the second covering layer 1414 is defined as the general term for the layered structure wrapped around the outer circumferential surface of the hollow tube 1412, and the third covering layer 1434 is defined as the general term for the layered structure wrapped around the filter medium 1432, and the specific configurations and forming materials of the first covering layer 123, the second covering layer 1414, and the third covering layer 1434 are not limited and can be set as needed to meet different requirements.

[0046] In the present application, the first cladding layer 123 cladding the substrate body 121 is provided with substrate section air inlet holes 123a communicating the inner and outer surfaces thereof, and the distance from the substrate section air inlet holes 123a to the end surface of the substrate section 120 connected to the confluence filter section 140 is greater than 0 mm and less than 1 mm. Specifically, since the first cladding layer 123 is formed by laminating the substrate section cladding layer cladding the substrate body 121 and the connecting layer cladding the end of the substrate section cladding layer close to the sub-confluence section 141, the substrate section air inlet holes 123a penetrate the substrate section cladding layer and the connecting layer in the thickness direction.

[0047] In this way, by providing the substrate section air inlet holes 123a at a position where the distance from the first cladding layer 123 to the end surface of the confluence filter section 140 connected thereto is less than 1 mm, the air intake into the sub-confluence section 141 and the total ventilation rate can be effectively increased. When the user generates a negative pressure at the end surface of the aerosol generating article 100 away from the substrate section 120 by suction, it is easier to gradually carry out the nicotine and flavor substances generated by the substrate body 121 during heating, thereby having better suction consistency and effectively improving the user's experience. Moreover, since the substrate section air inlet holes 123a are provided very close to the end surface of the substrate section 120, the air flow through the substrate body 121 can be minimized, thereby maximizing the negative pressure and oxygen-poor state of the substrate body 121, better releasing the effective substances in the aerosol forming substrate, and ensuring that the temperature of the substrate body 121 is relatively stable during the dynamic process of suction, so that the release amount of the aerosol remains consistent.

[0048] In some embodiments, the substrate section 120 is provided with a plurality of substrate section air inlet holes 123a, and all the substrate section air inlet holes 123a are arranged at intervals along the circumference of the confluence filter section 140. In this way, the air flow outside the aerosol generating article 100 can be divided into the substrate section 120 through the plurality of substrate section air inlet holes 123a. As a preferred embodiment, the number of substrate section air inlet holes 123a is 2 to 20. It can be understood that the number of substrate section air inlet holes 123a is not limited and can be set as needed to meet different suction requirements, for example, the number of substrate section air inlet holes 123a is 16 or 12.

[0049] Further in some embodiments, according to the different air flow rates of different regions, the substrate section air inlet holes 123a are arranged at non-constant intervals along the circumference of the substrate section 120, that is, the distance between at least some adjacent two substrate section air inlet holes 123a is different from the distance between the remaining adjacent two substrate section air inlet holes 123a. It can be understood that in other embodiments, all the substrate section air inlet holes 123a can be arranged at constant intervals along the circumference of the substrate section 120, that is, the distance between adjacent two substrate section air inlet holes 123a is equal.

[0050] In some embodiments, the sub-converging section 141 is provided with at least one group of sub-converging section air inlet holes 1414b, and each group of sub-converging section air inlet holes 1414b is in communication with the cavity 1414a and the external environment. Since the sub-converging section 141 comprises the cavity tube 1412 and the second cladding layer 1414 cladded on the outer circumferential surface of the cavity tube 1412, and the second cladding layer 1414 is formed by stacking the sub-converging section cladding layer cladded on the cavity tube 1412 and the converging filter section cladding layer cladded on the sub-converging section cladding layer, the sub-converging section air inlet holes 1414b are formed through the cavity tube 1412, the sub-converging section cladding layer and the converging filter section cladding layer. In this way, the airflow outside the aerosol generating article 100 can enter the cavity 1414a of the sub-converging section 141 through the sub-converging section air inlet holes 1414b, thereby further improving the air intake amount and the total ventilation rate of the aerosol generating article 100.

[0051] In some embodiments, the distance between the sub-converging section air inlet holes 1414b and the sub-filter section 141 is 1 mm-10 mm. It can be understood that the distance between the sub-converging section air inlet holes 1414b and the sub-filter section 141 is not limited and can be set as required to meet different requirements.

[0052] In particular, in some embodiments, the sub-converging section 141 is provided with multiple groups of sub-converging section air inlet holes 1414b, each group of sub-converging section air inlet holes 1414b is arranged at intervals in the axial direction of the sub-converging section 141, each group of sub-converging section air inlet holes 1414b comprises multiple sub-converging section air inlet holes 1414b, all the sub-converging section air inlet holes 1414b in the same group are arranged at intervals in the circumferential direction of the sub-converging section 141, the distance between adjacent two groups of sub-converging section air inlet holes 1414b can be the same or different, and each sub-converging section air inlet hole 1414b in adjacent two groups of sub-converging section air inlet holes 1414b can be arranged one by one in the axial direction of the sub-converging section 141 or staggered.

[0053] Preferably, the sub-converging section 141 is provided with one, two or three groups of sub-converging section air inlet holes 1414b, and the number of sub-converging section air inlet holes 1414b in each group is 2-20. It can be understood that the number of groups of sub-converging section air inlet holes 1414b and the number of sub-converging section air inlet holes 1414b in each group of sub-converging section air inlet holes 1414b are not limited and can be set as required to meet different requirements. For example, the number of sub-converging section air inlet holes 1414b in each group is 16 or 12.

[0054] Further, in some embodiments, all the sub-converging section air holes 1414b in the same group are equidistantly arranged along the circumference of the sub-converging section 141, i.e., the distance between every two adjacent sub-converging section air holes 1414b is equal. In other embodiments, according to the different air flow rates of different regions, the sub-converging section air holes 1414b in the same group are not equidistantly arranged along the circumference of the sub-converging section 141, i.e., the distance between at least some two adjacent sub-converging section air holes 1414b is not equal to the distance between the other two adjacent sub-converging section air holes 1414b.

[0055] The above aerosol generating article 100 can significantly improve the air intake and total ventilation rate of the aerosol generating article 100 by providing the substrate section air hole 123a with a distance of 0mm-1mm from the end face of the substrate section 120 to which the filter section 140 is connected. Since the distance of the substrate section air hole 123a to the filter section 140 is close enough, the nicotine and flavor substances generated by the substrate body 121 during the heating of the aerosol generating article 100 can be fully analyzed and carried out by the airflow, thereby increasing the user's experience. Moreover, the airflow outside the aerosol generating article 100 can also enter the cavity 1414a of the sub-converging section 141 through the sub-converging section air hole 1414b, thereby further improving the air intake and total ventilation rate of the aerosol generating article 100.

[0056] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.

[0057] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
