The detailed features and advantages of the utility model are described in the following detailed description, which is sufficient to enable one skilled in the art to understand the technical content of the utility model and to implement the utility model, and the related objects and advantages of the utility model can be easily understood by one skilled in the art from the description, the claims and the accompanying drawings.

As used herein, the term "longitudinal" refers to a direction corresponding to a major longitudinal axis of an aerosol-generating device, the direction extending between an upstream end and a downstream end of the aerosol-generating device. The term "height" refers to the length of an object that extends in the longitudinal direction.

As used herein, "aerosol-generating device" refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol-forming substrate may be part of an aerosol-generating article. An aerosol-generating device may comprise one or more components for supplying energy from a power source to an aerosol-forming substrate to produce an aerosol. For example, the aerosol-generating device may be a heated aerosol-generating device. The aerosol-generating device may be an electrically heated aerosol-generating device or a gas-heated aerosol-generating device. The aerosol-generating device may be an aerosol-generating device which interacts with an aerosol-forming substrate of an aerosol-generating article to generate a gas which may be inhaled through a user's mouth directly into the user's lungs. The aerosol-generating device may be a holder.

As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol. For example, the aerosol-generating article may be an aerosol-generating article that generates a gas that can be inhaled through the mouth of a user directly into the lungs of the user. The aerosol-generating article may be disposable. The term "aerosol-generating article" is generally used hereinafter.

As used herein, the term "aerosol-forming substrate" relates to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may suitably be an aerosol-generating article or a part of an aerosol-generating article.

Preferably, the aerosol-generating article is a heated aerosol-generating article which is an aerosol-generating article comprising an aerosol-forming substrate which is intended to be heated rather than combusted in order to release volatile compounds which can form an aerosol. The aerosol formed by heating the aerosol-forming substrate may contain less known harmful constituents than known harmful constituents produced by combustion or thermal degradation of the aerosol-forming substrate. The aerosol-generating article may be or may comprise a tobacco stem.

As used herein, the term "flat disc" refers to an element whose surface facing the insertion opening for an aerosol-generating article is of substantially equal longitudinal height at various points in the horizontal direction, the term indicating its outer shape profile to distinguish it from a cupped container. The term does not limit the physical or chemical properties of the material, texture, structure, etc. The plate may include cutouts for ventilation, for heater access or weight reduction, etc. The surface of the flat disc may have a portion of a protrusion to reduce the contact area with the aerosol-generating article or to increase the ventilation path, etc., the height of the protrusion being limited to not exceed the radius of the flat disc.

As used herein, the term "heating chamber" refers to a chamber of an aerosol-generating device for containing the aerosol-forming substrate. A heater is typically provided within or around the heating chamber. The electrical heater may comprise an internal electrical heating element for at least partial insertion into the aerosol-generating article when the aerosol-generating article is received in the extractor and the extractor is in the first position. An "internal heating element" is an element adapted to be inserted into an aerosol-forming material. The aerosol-generating article adheres to the heating element and therefore breaks when the aerosol-generating article is separated from the heating element.

Alternatively or additionally, the electric heater may comprise an external heating element. The term "external heating element" refers to an external heating element that at least partially surrounds an aerosol-generating article. The electric heater may include one or more internal heating elements and one or more external heating elements.

The electric heater may comprise a single heating element. Alternatively, the electric heater may comprise more than one heating element. The heating element(s) may be suitably arranged so as to most effectively heat the aerosol-generating article.

The electric heater may comprise a resistive material. Suitable resistive materials include, but are not limited to: semiconductors such as doped ceramics, electrically "conductive" ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composites made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and metals from the platinum group. Examples of suitable metal alloys include: stainless steel; nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-titanium-zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys; and superalloys based on nickel, iron, cobalt stainless steel; and iron-manganese-aluminum based alloys. In a composite material, the resistive material may be selectively embedded in, encapsulated or coated with an insulating material, or vice versa, depending on the energy transfer kinematics and the desired external physicochemical properties. Alternatively, the electric heater may comprise an infrared heating element, a photon source, or an induction heating element.

The electric heater may take any suitable form. For example, the electric heater may take the form of a heating blade. Alternatively, the electric heater may take the form of a housing or substrate having different electrically conductive portions, or a resistive metal tube. Alternatively, there may be one or more heater pins or rods which extend through the centre of the aerosol-generating article as has been described. Alternatively, the electric heater may be a disc (end) heater or a combination of a disc heater and a heating pin or rod. Other alternatives include heating wires or filaments, such as Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wires or heating plates. Alternatively, the heating element may be deposited in or on a rigid carrier material.

The electric heater may comprise a heat sink or reservoir comprising a material capable of absorbing and storing heat and subsequently releasing heat to the aerosol-generating article over time. The heat sink can be formed of any suitable material, such as a suitable metal or ceramic material. In one embodiment, the material has a high thermal capacity (sensible heat storage material), or is a material capable of absorbing heat and subsequently releasing the heat via a reversible process (e.g., high temperature phase change). Suitable sensible heat storage materials include: silica gel; alumina; carbon; a glass pad; glass fibers; minerals; metals or alloys, such as aluminum, silver or lead; and cellulosic materials such as paper. Other suitable materials that release heat via a reversible phase change include paraffin, sodium acetate, naphthalene, wax, polyethylene oxide, metals, metal salts, mixtures or alloys of eutectic salts.

The heat sink or heat reservoir may be arranged such that it is in direct contact with the aerosol-generating article and may transfer the stored heat directly to the substrate. Alternatively, heat stored in a heat sink or heat reservoir may be transferred to the aerosol-generating article by means of a heat conductor (such as a metal tube).

The electric heater may heat the aerosol-generating article by means of conduction. The electric heater may be at least partially in contact with a substrate or a carrier on which the substrate is deposited. Alternatively, heat from the electric heater may be conducted to the substrate by means of a heat conducting element.

Alternatively, the electric heater may transfer heat to incoming ambient air which is drawn through the electrically heated smoking system during use, which in turn heats the aerosol-generating article by convection. The ambient air may be heated prior to passing through the aerosol-generating article.

As used herein, the term "first position/second position" refers to the position of the extractor when a cigarette is installed/removed from the heating chamber, in particular the first position is an operating position defined by heating the aerosol-generating article into a heated position of the heating chamber, and the second position is an extraction position defined by heating the aerosol-generating article separately from the heating chamber.

As used herein, the term "direction of motion" refers to the direction of movement of the components of the extractor during installation or extraction of the aerosol-forming substrate. When it is described herein that the directions of movement of the plurality of components are the same, it means that the directions of synchronous movement of the components in the same process are the same. And vice versa.

As used herein, the term "flexible linkage" refers to a flexible, high temperature resistant, elongated strip-like structure that connects the platform and the operating portion, such that the flexible linkage moves the platform when the operating portion is moved. The flexible connecting member may be in the form of a wire, a ribbon, or a chain.

It is an object of the present invention to provide a safer and more hygienic smoking set extraction structure for the user, and to develop a new aerosol generating device. The novel aerosol-generating device reduces the corners of the aerosol-generating device that are prone to dirt and grime by improving on conventional cup-shaped container extractors, and makes the process of extracting the aerosol-generating article less scaly. Specific embodiments of this scheme will be described in detail below:

the aerosol-generating device 1 disclosed in one embodiment as shown in fig. 1 comprises a heating chamber 11 for containing an aerosol-generating article 13 and an extractor 2 for extracting the aerosol-generating article 13 contained in the aerosol-generating device 1.

The extractor 2 includes a flat plate 21 and an operating portion 22. the flat plate 21 is disposed inside the heating chamber 11. The operation unit 22 is provided outside the aerosol-generating device 1. The thickness, material and position of the operating portion 22 are sufficient that the operating portion 22 is not conducting excessive heat during operation of the aerosol-generating device 1.

The flat plate 21 is moved to and from the first position and the second position by the operation portion 22. The flat disk 21 and the operation portion 22 move in the same direction, and for example, when the aerosol-generating product 1 is extracted, the operation portion 22 moves upward, and the flat disk 21 follows the operation portion 22 and moves upward. The flat plate 21 and the operation part 22 are directly connected, and the connection mode can be magnetic connection through the cavity wall of the heating cavity.

The aerosol-generating device 1 disclosed in one embodiment as shown in figure 2 comprises a heating chamber 11 for containing an aerosol-generating article 13 and an extractor 2 for extracting the aerosol-generating article 13 contained in the aerosol-generating device 1.

The extractor 2 includes a flat disc 21 and an operating portion 22. the flat disc 21 is disposed inside the heating chamber 11. The operation unit 22 is provided outside the aerosol-generating device 1. The thickness, material and position of the operating portion 22 are sufficient that the operating portion 22 is not conducting excessive heat during operation of the aerosol-generating device 1. The flat plate 21 and the operation portion 22 are connected by a flexible connection member 23.

The flexible connecting member 34 is disposed along the inner wall of the heating chamber 11 and the outer wall of the housing 12 of the aerosol-generating device 1 through a stopper. In another embodiment, the flexible connecting member 23 may be disposed along the inner wall of the heating cavity 11 and enter the space between the heating cavity 11 and the housing 12, and the flexible connecting member 23 may be fixed by providing a through slot on the housing 12 for the operation portion 22 to move up and down, so that the flexible connecting member 23 can be connected with the operation portion 22.

The position limiting member is required to fix the position of the flexible connecting member 23 relatively and ensure smooth movement of the flexible connecting member 23. When the flexible connecting member 23 is parallel to the contact surface, the limiting member may be an inner groove, a positioning through groove, a limiting ring, or the like. When the flexible connecting element 34 is perpendicular to the contact surface, the limiting element may be a fixed pulley, a limiting ring, a curved groove, or the like.

The flat plate 21 is moved to and from the first position and the second position by the operation portion 22. The flat disc 21 and the operating part 22 move in opposite directions, for example, when the aerosol-generating article 1 is extracted, the operating part 22 moves downwards to pull the flexible connector 23, and the flat disc 21 is pulled by the flexible connector 23 and moves upwards along with the flexible connector 23, so that the aerosol-generating article 13 is taken out.

Longitudinal guide grooves may be provided at the axisymmetric positions of the flexible connecting member 23 to provide a guiding and fixing function for the flat disc 21, thereby allowing the flat disc 21 to be balanced during movement.

The aerosol-generating device 1 disclosed in one embodiment as shown in figure 3 comprises a heating chamber 11 for containing an aerosol-generating article 13 and an extractor 2 for extracting the aerosol-generating article 13 contained in the aerosol-generating device 1.

The extractor 2 includes a flat disc 21 and an operating portion 22. the flat disc 21 is disposed inside the heating chamber 11. The operation unit 22 is provided outside the aerosol-generating device 1. The thickness, material and position of the operating portion 22 are sufficient that the operating portion 22 is not conducting excessive heat during operation of the aerosol-generating device 1. The flat plate 21 and the operation portion 22 are connected by a plurality of flexible connecting members 23 arranged axisymmetrically. The handle 22 may be provided at the bottom of the aerosol-generating device 1.

The flexible connection 23 is provided along the inner wall of the heating chamber 11 and the outer wall of the housing 12 of the aerosol-generating device 1 by a stopper. In another embodiment, the flexible linkage 23 may also be disposed along the inner wall of the heating chamber 11 and into the space between the heating chamber 11 and the housing 12.

The position limiting member is required to fix the position of the flexible connecting member 23 relatively and ensure smooth movement of the flexible connecting member 23. When the flexible connecting member 23 is parallel to the contact surface, the limiting member may be an inner groove, a positioning through groove, a limiting ring, or the like. When the flexible connecting member 23 is perpendicular to the contact surface, the limiting member may be a fixed pulley, a limiting ring, a curved groove, or the like.

In this embodiment, when the flat disc 21 is in the second position, a portion of the flexible connector 23 leaves the aerosol-generating device 1, which is likely to be cumbersome and inconvenient for the user to use. The aerosol-generating device 1 may therefore be provided with a hub to receive the pulled-out flexible connector 23.

The flat disc may be of various shapes sufficient to support an aerosol-generating article, provided that the flat disc is a substantially planar member. The shape of the flat disk may be the same or scaled down as the shape of the heating chamber cross-section as shown in fig. 4. As shown in fig. 5, the flat disc may also be shaped as a bar. In one embodiment, the flat disc may be an extension of the flexible connector.
