Description

Technical Field

[0001] The utility model relates to the field of aerosol supply, in particular to an aerosol generating product and an aerosol supply system. Background Art

[0002] The aerosol supply system includes an aerosol supply device and an aerosol generating product (such as a tobacco product). The aerosol generating product is inserted into the heating chamber of the aerosol supply device, and the aerosol generating product is heated by the aerosol supply device to obtain an aerosol. This heat-not-burn technology allows the aerosol generating product to release active ingredients in the carbonization stage before combustion, thereby minimizing the generation of tar and harmful substances.

[0003] The typical design of aerosol-generating products is to use packaging materials to wrap the aerosol-forming matrix. The packaging materials are generally rolled into a cylindrical shape with openings at both ends for ventilation. During the heating process of the aerosol-generating product by the aerosol supply device, the heat transferred to the inside of the aerosol-generating product is easily dissipated through the end openings of the packaging material, resulting in a slow temperature rise of the aerosol-forming matrix. The heat diffusion to the outside will also cause the surface temperature of the aerosol supply device to rise, resulting in the device being hot during the inhalation process. Utility Model Content

[0090] A consumable is an article comprising or consisting of an aerosol generating material, some or all of which is intended to be consumed by a user during use. A consumable may include one or more other components, such as an aerosol generating material storage area, an aerosol generating material delivery component, an aerosol generating area, a housing, a wrapper, a mouthpiece, a filter and / or an aerosol modifier. A consumable may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol generating material to generate an aerosol. The heater may, for example, include a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0091] A susceptor is a material that can be heated by being penetrated with a varying magnetic field (e.g., an alternating magnetic field). The susceptor can be a conductive material such that its penetration by the varying magnetic field results in inductive heating of the heated material. The heated material can be a magnetic material such that its penetration by the varying magnetic field results in hysteresis heating of the heated material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this article, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

The aerosol modifier may be disposed in an aerosol modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifier may include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, string, or particle form. The aerosol modifier may be free of filter material.

[0093] An aerosol generator is a device configured to cause an aerosol to be generated from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol generating material to thermal energy so as to release one or more volatiles from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol generating material without heating. For example, the aerosol generator can be configured to subject the aerosol generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0094] The present disclosure relates to an aerosol supply system (which may also be referred to as a vapor supply system), such as a sprayer or an electronic cigarette. In the following description, the term "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term can be used interchangeably with aerosol supply system / device and electronic aerosol supply system / device. In addition, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "aerosolization" and "aerosolization" are often used interchangeably.

[0095] Aerosol supply systems (electronic cigarettes) typically (although not always) include modular components, which include a reusable device part and a replaceable (disposable / consumable) cartridge part. Typically, the replaceable cartridge part will include an aerosol generating material and a vaporizer (which can be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device part includes a temperature sensor for helping to control the temperature in some cases. The cartridge is electrically and mechanically connected to the control unit for use, for example, using a thread, a bayonet, or a magnetic connection with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is exhausted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part and the replacement cartridge is attached to its appropriate position. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems / devices.

[0096] Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system using a disposable cartridge. However, it will be understood that the basic principles described herein may be equally applicable to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and single-use disposables, and other overall shapes, such as high-performance devices based on so-called box-shaped models that typically have a box shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol supply system that is operationally configured to provide functionality according to the principles described herein, and that the structural aspects of the system configured to provide functionality according to certain embodiments of the present disclosure are not primarily important.

[0097] This embodiment provides an aerosol generating product, such as Figure 1As shown, the aerosol-generating article 10 comprises an aerosol-forming substrate 101, an end element 102 and a packaging material 103. The aerosol-forming substrate 101 is capable of forming an aerosol under heating conditions. The end element 102 is arranged upstream of the aerosol-forming substrate 101, and the end element 102 is made of a heat-insulating substrate and has an airflow channel. The aerosol-forming substrate 101 is located on the air outlet side of the end element 102. The packaging material 103 is coated on the outside of the aerosol-forming substrate 101 and the end element 102.

[0098] Among them, the caliber of the airflow channel on the end element 102 is smaller than the end opening of the packaging material 103, and the opening at the end of the packaging material 103 is partially shielded by the end element 102, thereby preventing the heat inside the aerosol generating product 10 from escaping from the end opening of the packaging material 103 without blocking ventilation. The thermal conductivity of the thermal insulation substrate is less than 0.040W / (m·K). Preferably, the thermal conductivity of the thermal insulation substrate can be configured to be less than 0.030W / (m·K), less than 0.020W / (m·K) or less than 0.010W / (m·K). Since the end element 102 is made of a thermal insulation substrate with low thermal conductivity, it can further prevent heat from being conducted to the outside of the aerosol generating product 10.

[0099] The aerosol-forming substrate 101 releases active ingredients when heated, and the user causes air to enter the aerosol-forming substrate 101 through a suction action, mix with the active ingredients released by the aerosol-forming substrate 101, and then enter the oral cavity. In order to allow air to enter the aerosol-forming substrate 101, an air inlet 105 in fluid communication with the aerosol-forming substrate 101 is provided on the aerosol-generating article 10. In this embodiment, the air inlet 105 is arranged upstream of the aerosol-forming substrate 101, and specifically, the air inlet 105 is provided on the end element 102.

[0100] In one possible implementation, the air inlet 105 is located at the end of the end element 102 opposite to the aerosol-forming substrate 101, see Figure 1 , Figure 2 and Figure 3 As shown, air may enter from the bottom surface of the aerosol-generating article 10 upstream.

[0101] In another possible implementation, the air inlet 105 is located on the circumferential surface of the end element 102, see Figure 6-Figure 8As shown, air can enter from the upstream side wall of the aerosol generating article 10. Among them, when the circumferential surface of the end element 102 provided with the air inlet hole 105 is covered by the packaging material 103, the area on the packaging material 103 corresponding to the air inlet hole 105 is also provided with a hole 106 penetrating the packaging material 103, and the air inlet hole 105 of the end element 102 is connected with the hole 106 of the packaging material 103, and the external air can enter the aerosol forming matrix 101 through the hole 106 of the packaging material 103 and the air inlet hole 105 of the end element 102. Specifically, one or more holes are provided on the packaging material 103. When there are multiple holes 106 on the packaging material 103, the multiple holes are arranged along the circumference of the packaging material 103. Preferably, the holes 106 on the packaging material 103 correspond one-to-one with the air inlet holes 105 of the end element 102 and are connected to each other.

[0102] In this embodiment, the heat insulating substrate is a porous structure or a heat insulating sheet. When the heat insulating substrate is a porous structure, the holes on the heat insulating substrate constitute an air flow channel. When the heat insulating substrate is a heat insulating sheet, the heat insulating substrate forms the end element 102 by winding and / or folding.

[0103] In a possible implementation, the heat-insulating sheet forms a plurality of heat-insulating tubes disposed inside and outside, the length direction of the heat-insulating tubes is consistent with the length direction of the aerosol generating article 10, and there is a radial gap between two adjacent heat-insulating tubes, and the radial gap forms at least part of the airflow channel. Optionally, the heat-insulating tube has a flange at at least one end in the axial direction, and there is an axial gap between the flanges of adjacent heat-insulating tubes, and the axial gap communicates with the radial gap to form at least part of the airflow channel.

[0104] In another possible implementation, the heat insulation sheet is spirally wound to form a spiral structure, and there is an axially penetrating gap between two radially adjacent layers of the spiral structure, and these gaps form an air flow channel. Optionally, grooves can also be provided on the heat insulation sheet, and when the heat insulation sheet is wound into a spiral structure, if two radially adjacent layers fit together, these grooves can form an axially penetrating gap.

[0105] In another possible implementation, the heat insulating sheet has a pleated configuration, which includes alternating first pleated surfaces 107 and second pleated surfaces 108, and grooves 109 are formed between adjacent first pleated surfaces 107 and second pleated surfaces 108, and the grooves 109 serve as at least part of the airflow channel. Figure 4 and Figure 5 As shown, the pleated heat-insulating sheet is wound into a spiral structure, and even if two radially adjacent layers of the spiral structure are attached, the groove 109 between the first pleated surface 107 and the second pleated surface 108 can still allow air to pass through. Figure 4 This pleated configuration plus spiral winding structure has good supporting strength, and the aerosol generating article 10 is not easy to break or bend when inserted into the aerosol supply device 20.

[0106] The aerosol generating article 10 may further include an end cap 110, which is located at one end of the end element 102 away from the aerosol forming substrate 101 and seals the end, and the air inlet 105 is provided on the circumferential surface of the end element 102. Figure 6-Figure 8 The end cap 110 has a plug hole 112, and the end element 102 is provided with a through hole 111 along the length direction, the through hole 111 is connected to the plug hole 112, and the through hole 111 is coaxially arranged with the plug hole 112. When the aerosol generating product 10 is set on the aerosol supply device 20, the puncture member 205 on the aerosol supply device 20 can enter the aerosol-forming substrate 101 through the plug hole 112 on the end cap 110 and the through hole 111 on the end element 102 in sequence. The end cap 110 is made of a deformable material, and when the puncture member 205 is inserted into the aerosol generating product 10, the puncture member 205 and the plug hole 112 are transitionally fitted or interference fit.

[0107] In this embodiment, the heat insulating substrate is a porous material, in order to prevent the puncture member from directly contacting the heat insulating substrate to produce an unpleasant odor and destroy the smoking taste. In a possible implementation, Figure 7 As shown, the diameter of the through hole 111 is set to be larger than the diameter of the piercing member 205. When the piercing member 205 is inserted into the aerosol generating article 10, there is a gap between the piercing member 205 and the wall of the through hole 111, and the piercing member 205 is not in direct contact with the heat insulating substrate. In another possible implementation, as Figure 8 and Fig. 9 As shown, a lining member 113 is provided in the through hole 111 of the end element 102, and the lining member 113 has a hollow channel 104 for the puncture member 205 to be inserted. The puncture member 205 penetrates the hollow channel 104 of the lining member 113, and the lining member 113 plays a role in isolating the puncture member 205 from the heat-insulating substrate. Preferably, the lining member 113 is a rigid hollow tube, which has a good supporting effect, and the lining member 113 will not be squeezed and deformed during the insertion of the puncture member 205.

[0108] In a possible implementation, the end element 102 further includes a heating element, which is disposed inside the end element 102. During the heating process of the aerosol generating article 10, the heating element generates heat, thereby preheating the air entering the end element 102, thereby improving the user's puffing experience. The heating element is made of electromagnetic induction material and can generate heat in an electromagnetic field. The electromagnetic induction material can be, for example, iron, cobalt, nickel, gadolinium, erbium, or alloys thereof.

[0109] In a possible implementation, at least one electromagnetic induction heating element 114 is further provided in the aerosol-forming substrate 101 , and the electromagnetic induction heating element 114 is configured to heat the aerosol-forming substrate 101 .

[0110] To facilitate the preparation of aerosol-generating articles, the electromagnetic induction heating element 114 may be combined with the end element 102, such as Figure 2 As shown, one end of the electromagnetic induction heating element 114 is combined with the end element 102, and the other end enters the aerosol-forming substrate 101. When the aerosol-generating article 10 is in an electromagnetic field, the electromagnetic induction heating element 114 generates heat and can heat the aerosol-forming substrate 101. Further, a part of the electromagnetic induction heating element 114 can be arranged in the end element 102, and when the aerosol-generating article 10 is in an electromagnetic field, the part of the electromagnetic induction heating element 114 in the aerosol-forming substrate 101 can heat the aerosol-forming substrate 101, and the part of the electromagnetic induction heating element 114 in the end element 102 can preheat the air that is about to enter the aerosol-forming substrate 101.

[0111] Since the electromagnetic induction heating element can heat the aerosol-forming substrate from the inside, when used in conjunction with the aerosol supply device with circumferential heating, the inside and outside of the aerosol-forming substrate can be heated simultaneously, and the heating efficiency is high, and the aerosol-forming substrate is heated evenly, which can improve the puffing taste. In addition, since the aerosol-forming substrate can be heated by the electromagnetic induction heating element, even if the piercing member on the aerosol supply device is removed, aerosol can still be successfully generated.

[0112] This embodiment also provides an aerosol supply system, which includes an aerosol supply device and the above-mentioned aerosol generating product. The aerosol supply device includes a shell, and the shell is provided with a cavity for receiving the aerosol generating product. The aerosol generating product is removably arranged in the cavity. The heating method of the aerosol supply device is a resistance heating method and / or an electromagnetic induction heating method.

The aerosol supply device 20 includes a housing, a heating module and an energy supply module 204. The heating module and the energy supply module 204 are arranged in the housing. The housing is provided with a cavity for receiving the aerosol generating product 10. The heating module includes a piercing member 205. The piercing member 205 at least partially enters the cavity. The energy supply module 204 is electrically connected to the piercing member 205. When the aerosol generating product 10 is received in the cavity, the piercing member 205 passes through the end element 102 and enters the aerosol-forming substrate 101. The piercing member 205 generates heat after being energized, thereby heating the aerosol generating product 10.

The aerosol supply device 20 includes a housing, a heating module and an energy supply module 204. The heating module and the energy supply module 204 are arranged in the housing.

The heating body 202 is arranged in the cavity, the coil 203 is wound on the outside of the cavity, and the energy supply module 204 is electrically connected to the coil 203. The heating body 202 is made of magnetic induction material. When the aerosol generating product 10 is received in the cavity, the heating body 202 surrounds the aerosol generating product 10. After the coil 203 is energized, the heating body 202 is in the electromagnetic field generated by the coil 203 and generates heat, thereby heating the aerosol generating product 10.
