Definitions

  • the present disclosure relates to the field of smoking device, and in particular to a non-combustion smoking device.
  • the existing non-combustion smoking devices typically generate smoke from smoking devices by heating.
  • Such non-combustion smoking devices comprise a heating cavity containing smoke products.
  • the smoke product By inserting a smoke product into the heating cavity of the non-combustion smoking device and starting the heater to heat the smoking device, the smoke product generates smoke for users.
  • FIG. 1 discloses an aerosol-generating device comprising a housing, a heating element, an air inlet 26 and an air flow channel 28.
  • the housing has a proximal end and a distal end and comprises at least one outer surface and one inner surface.
  • the inner surface at the proximal end defines an end-opening cavity, in which an aerosol-forming substrate is housed.
  • the cavity has a longitudinal extending portion between its proximal and distal ends.
  • a heating element is located within the cavity and configured to heat the aerosol-forming substrate contained in the cavity.
  • the airflow channel 28 extends from the air inlet 30 to the distal end of the cavity between the inner surface and the outer surface of the housing.
  • the airflow channel 28 is arranged between the inner surface and the outer surface of the housing, the airflow channel is relatively narrow. After foreign matters such as dust enter during suction, the airflow channel becomes narrowed or even blocked, resulting in poor suction. Moreover, users often cannot easily clean such a narrow airflow channel arranged between the inner surface and the outer surface of the housing.
  • the housing of the aerosol-generating device not only forms the air flow channel, but houses various components such as battery, control circuit and the like. It is generally difficult for a user to separately remove the housing for cleaning.

  • a through hole is provided by penetrating an end wall of the first end of the extractor.
  • a plurality of through holes are provided, and each of the through holes is aligned with a corresponding groove.
  • the first end can comprise a gauze or screen fabric that allow air to flow through.
  • a thermal isolation groove is provided on the outer peripheral wall of the extractor and/or a cavity wall of the heating cavity.
  • a thermal isolation material can be provided in the thermal isolation groove.
  • first”, “second”, etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as “first”, “second”, etc. can explicitly or implicitly comprise one or more of the features. In the description of the present disclosure, the meaning of "a plurality of' is two or more, unless explicitly defined otherwise.
  • All directional indicators in the present disclosure such as up, down, left, right, front, back, etc., are used to explain the positional relationship, the movement situation and the like among various components in a certain posture (generally the posture shown in the drawings). If the specific posture changes, the directional indication changes accordingly.
  • a connection can be a fixed connection or a detachable connection or an integral connection; a connection can be a mechanical connection or an electrical connection; a connection can be a direct connection or an indirect connection through an intermediate medium, or an internal connection of two components.

  • the cavity wall 22 is in the form of a generally cylindrical tube with an inner diameter slightly larger than an outer diameter of the extractor 3 so that the extractor 3 can be slidably received in the heating cavity.
  • the smoke product 4 has an elongated cylindrical shape, and comprises an aerosol-forming substrate 41 and a filter tip rod.
  • the aerosol-forming substrate 41 and the filter tip rod are successively arranged and aligned coaxially.
  • the aerosol-forming substrate 41 and the filter tip rod are wrapped with an external paper wrapper.
  • a smoke product which can comprise other components.
  • the heater 21 extends through an eyelet in the first end of the extractor 3 and is inserted into the aerosol-forming substrate 41 of the smoke product 4 located in the receiving cavity of the extractor 3.
  • an air inlet channel extending from the second end to the first end of the extractor 3 is provided on the inner peripheral wall of the extractor 3.
  • the air inlet channel is a groove 31 formed on the inner peripheral wall of the extractor 3.
  • the air inlet channel is a plurality of grooves 31 formed evenly on the inner peripheral wall of the extractor 3 along the inner periphery of the extractor 3.
  • the groove 31 is a linear groove extending straightly from the second end of the extractor to the first end.
  • the groove 31 is a spiral groove (not shown) that extends spirally from the second end of an extractor to the first end.
  • a spiral airflow as formed can take away more heat emitted from the smoke product.
  • dust or other debris carried by an air flow is more likely to accumulate near the second end of the extractor under a drive of a centrifugal force, which is more convenient for subsequent cleaning.
  • the inner peripheral wall of the extractor 3 in the form of a sleeve can have a non-circular profile (not shown), such as an oval profile, a triangular profile, a polygonal profile and the like.
  • a gap between the inner peripheral wall of the non-circular profile and the outer peripheral wall of the circular profile of the smoke product 4 forms an air inlet channel in the form of a groove.
  • the outer peripheral wall of the smoke product 4 can have any profile different from it. As long as a gap can be formed therebetween, such air inlet channel can be formed.
  • the extractor has a pentagonal inner peripheral wall, while the smoking device has a hexagonal outer peripheral wall, and so on.
  • a part of the inner peripheral wall of the extractor 3 can be formed with a profile matching the outline of the outer peripheral wall of the smoke product.
  • the air inlet channel has an air inlet 30 at the second end of the extractor 3.
  • Each air inlet 30 is in fluid communication with a corresponding groove. In the embodiment shown in Fig. 2 , the air inlet 30 is actually an end of the corresponding groove 30.
  • the size of the air inlet 30 can be selected by the designer and can be selected to provide a desired suction resistance via the device.
  • a through hole 32 is provided by penetrating the end wall of the first end of the extractor 3.
  • the number and size of through holes 32 correspond to the number and size of grooves 31.
  • Each through hole 32 can be aligned with a corresponding groove 31.
  • the number, position and size of the through holes can be changed according to specific operating parameters.
  • a groove (not shown) for guiding an airflow into the aerosol-forming substrate can be formed inside the end wall.
  • the user places the smoke product 4 comprising an aerosol-forming substrate 41 in the receiving cavity of the extractor 3.
  • the heater 21 extends through an eyelet in the end wall of the first end of the extractor 3 and is inserted into the aerosol-forming substrate 41 of the smoke product 4.
  • the user activates the heater 21 and the heater 21 heats the aerosol-forming substrate 41 to form an aerosol.
  • an air from the external environment flows from the air inlet 30 located at the second end of the extractor 3 (i.e., the upper end in FIG. 2 ) into a groove 31 between the extractor and the smoke product.
  • the air travels along the groove 31 to the vicinity of the first end of the extractor 3 and enters the aerosol-forming substrate 41 of the smoke product through a gap between the inner wall of the first end of the extractor 3 and the aerosol-forming substrate end of the smoke product 4; and/or enters a gap between the body 2 and the first end of the extractor 3 through the through hole 32, and then enters the aerosol-forming substrate 41 of the smoke product via the eyelet, through which the heater passes, or other eyelets. Subsequently, the air that enters the aerosol-forming substrate 41 travels through the aerosol-forming substrate 41 carrying the aerosol formed by heating the aerosol-forming substrate 41. Finally, the air arrives at the filter tip rod of the smoke product 4 and thereby can be drawn into the user's mouth for smoking.
  • an air inlet is provided at the second end of the extractor, instead of on the housing or the side of the body as typically provided in the prior art. In this position, the possibility of an inadvertent blockage of the air inlet by a user's hand during usage is very small, which ensures smooth suction.
  • an air inlet channel in the form of a groove is located between the inner peripheral wall of the extractor and the outer peripheral surface of the smoke product.
  • An airflow formed during suction takes away the heat emitted from the smoke product. Therefore, the air is preheated before entering the aerosol-forming substrate 41. This preheating of air not only improves the efficiency of the smoking device, but ensures a more uniform temperature distribution within the aerosol-forming substrate.
  • a thermal isolation groove can be provided on the outer peripheral wall of the extractor 3, the cavity wall 22 and/or the inner peripheral wall of the housing 1.
  • a thermal isolation groove forms a thermal isolation space, the heat emitted from a heater during a heating process reaches the thermal isolation groove and is blocked by air in the thermal isolation space, thereby reducing the heat transferred to the housing 1.
  • a thermal isolation material can be placed in the thermal isolation groove.
  • a smoke product is a heating-type smoke product that comprises an aerosol-forming substrate, which is intended to be heated rather than burned in order to release volatile compounds that can form an aerosol.
  • An aerosol formed by heating an aerosol-forming substrate can contain less known harmful components than those that can be generated by combustion or thermal degradation of the aerosol-forming substrate.
  • a smoke product can be a tobacco rod, or can comprise a tobacco rod.
  • a heater comprises one or more heating elements.
  • a heating element can comprise a resistance material.
  • a heating element can be an infrared heating element, a photon source, or an induction heating element.
  • a heating element can be in any suitable form.
  • a heating element can be the form of a heating blade.
  • a heating element can be the form of a housing or a substrate with different conductive parts, or a resistive metal tube.
  • a heating element can be one or more heating needles or rods that extend through the interior of the aerosol-forming substrate.
  • Other alternative examples comprise heating wires or filaments, such as Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wires or heating plates.
  • a heating element can be deposited in or on a rigid support material.
  • one or more eyelets can be provided in the first end of the extractor.
  • the number of eyelets can be more than the number of the heating elements of the heater and can also be equal to the number of the heating elements of the heater. Eyelets should be sized to allow a heater to pass freely. Eyelets can have any suitable shape. For example, eyelets can be rectangular or circular. The shape of eyelets can be the same as the cross-sectional shape of the one or more heating elements.
  • the first end can comprise a gauze or screen fabric that can allow air to flow through.
  • An aerosol-forming substrate can be a solid aerosol-forming substrate.
  • an aerosol-forming substrate can comprise both solid and liquid components.
  • the aerosol-forming substrate can comprise a tobacco-containing material that comprises volatile tobacco flavoring compounds released from the substrate upon heating.
  • an aerosol-forming substrate can comprise a tobacco-free material.
  • An aerosol-forming substrate can further comprise an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.
