Definitions

  • the present application relates to the field of aerosol provision technology, and particularly to an aerosol provision device and an aerosol provision system.
  • Heat-not-burn aerosol provision devices are electronic products designed to mimic traditional cigarettes in terms of smoke, taste, and sensation. These products, also known as “heat-not-burn” products or tobacco heating devices, generate aerosols by heating — rather than combusting — an aerosol generating material, such as a tobacco substrate, which is then inhaled by the user.
  • aerosol provision devices are mainly classified into two types according to their heating methods: core heating and circumferential heating.
  • Core heating may more thoroughly bake and heat the articles used in aerosol provision devices and may raise the heating temperature more rapidly.
  • the heating components of core heating aerosol provision devices are mostly in the form of sheets or pins.
  • the articles used in these devices are mainly made of thin sheets with a relatively high moisture content.
  • an aerosol provision device comprising an extractor component, a heating component, and a connecting component.
  • the extractor component comprises an extractor body configured to accommodate a cigarette stick.
  • the heating component comprises a heating pin configured for insertion into the cigarette stick.
  • the connecting component comprises a spiral groove and a guiding member that mutually cooperate, wherein one of the spiral groove and the guiding member is arranged on the extractor component, and the other is arranged on the heating component. The guiding member moves along the spiral groove, thereby driving the extractor body to rotate relative to the heating pin.
  • the extractor component further comprises a first sleeve in which a first containment chamber is formed. In some embodiments of any of the above, a portion of the heating component is accommodated in the first containment chamber, and the spiral groove is arranged on the side wall of the first sleeve.
  • the heating component further comprises a heating element base, with the guiding member arranged on the side wall of the heating element base and the heating pin arranged at the center of the end of the heating element base facing the extractor component.
  • the heating pin By positioning the heating pin at the center of the end of the heating element base facing the extractor component, the heating pin may be inserted into the central position of the cigarette stick, which may provide more uniform heating of the cigarette stick and enhance the user experience.
  • the aerosol provision device further comprises a housing in which a limiting groove is formed, and the limiting groove extends longitudinally along the device.
  • a limiting block which is complementary to the limiting groove, is arranged on the outer side wall of the first sleeve and is configured to move longitudinally back and forth within the limiting groove along the device.
  • the first sleeve may be allowed to move longitudinally along the device under the effect of the limiting block and the limiting groove. This may restrict the first sleeve from rotating while permitting its longitudinal movement along the device, which may avoid or reduce issues such as the cigarette stick breaking or being damaged during the removal process.
  • the aerosol provision device further comprises a bottom base and a boosting structure.
  • the boosting structure is arranged between the first sleeve or the heating element base and the bottom base, when removing the cigarette stick from the device, the boosting structure applies a force to the first sleeve or the heating element base in the direction opposite to the boosting structure.
  • the boosting structure when removing the cigarette stick from the device, applies a force in the direction opposite to the boosting structure to the first sleeve or the heating element base, which may facilitate the removal of the cigarette stick from the device.
  • the boosting structure comprises an elastic component.
  • the elastic component applies an elastic force back to boosting structure toward the first sleeve or the heating element base in the direction opposite to the boosting structure.
  • the sum of the weight of the cigarette stick and the first sleeve or the heating element base and the friction between the guiding member and the spiral groove is greater than the elastic force of the elastic component.
  • the boosting structure comprises a first magnetic component arranged on the bottom base and a second magnetic component arranged on the first sleeve or the heating element base, wherein the first magnetic component magnetically repels with the second magnetic component.
  • the sum of the weight of the cigarette stick and the first sleeve or the heating element base and the friction between the guiding member and the spiral groove is greater than the repulsive force between the first magnetic component and the second magnetic component.
  • the heating component further comprises a heating element base, with the heating pin arranged on the surface of the heating base facing the extractor component; and a second sleeve, fixedly connected to the heating element base.
  • a second containment chamber is formed inside the second sleeve.
  • the heating pin and the extractor component are accommodated within the second containment chamber.
  • the spiral groove is opened on the side wall of the second sleeve.
  • the guiding member is arranged on the side wall of the extractor body.
  • the guiding member moves along the spiral groove, driving the extractor body to rotate relative to the second sleeve. This causes the cigarette stick to rotate relative to the heating pin, which may prevent or reduce aerosol generating material sticking to the heating pin or remaining in the chamber, thereby improving the hygiene of the device.
  • a protrusion structure is formed on the inner wall of the extractor body.
  • the protrusion structure When a cigarette stick is loaded into the extractor body, the protrusion structure has an interference fit with the cigarette stick.
  • the interference fit may cause the extractor body to move together when the cigarette stick is removed from the aerosol provision device.
  • the protrusion structure may be annular in shape.
  • the spiral groove may be a through hole or a blind hole.
