The holding element 50 defines a second chamber 51, while the holding element 50 is accommodated in the chamber 10, the second chamber 51 being adapted to receive and hold an aerosol-product 200 for use with the aerosol-generating device 100, i.e. the holding element 50 may carry the aerosol-product 200 together with it being accommodated in the chamber 10. At least a portion of the heating element 20 extends into the second chamber 51 to enable insertion of the heating element 20 into the aerosol article 200 for heating to generate an aerosol. It is readily understood that the power supply unit 40 may be a rechargeable battery cell or a non-rechargeable battery cell.

The aerosol-generating article preferably employs a tobacco-containing material that releases volatile compounds from a matrix upon heating; or may be a non-tobacco material capable of being heated and thereafter adapted for electrical heating for smoking. The aerosol-generating article preferably employs a solid matrix, which may comprise one or more of powders, granules, shredded strips, ribbons or flakes of one or more of vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco; alternatively, the solid substrate may contain additional volatile flavour compounds, either tobacco or non-tobacco, to be released when the substrate is heated. In this embodiment, the aerosol product 200 is described using a tobacco rod filled with tobacco material.

The heating element 20 is configured as an elongated pin or needle or sheet so as to be smoothly inserted into the aerosol article 200 for heating. In some embodiments, the heating element 20 is a resistive heating element that generates joule heat by supplying a direct current. Or in yet other implementations, the heating element 20 is a susceptor heating element made of a susceptor material that is penetrable by a varying magnetic field to generate heat. Or in yet other implementations, the heating element 20 is an infrared heating element that heats the aerosol-generating article 1000 by radiating infrared light.

In some embodiments, as shown in fig. 2 and 3, the inner wall of the second chamber 51 is formed with a longitudinally extending rib 52, the rib 52 includes a plurality of ribs and uniformly surrounds the inner wall of the second chamber 51, and the plurality of ribs 52 enclose a holding space, so that when the aerosol product 200 is received in the second chamber 51, the aerosol product 200 can be held by the plurality of ribs 52 to be held in the holding space.

With continued reference to fig. 3 and 4, the retaining member 50 is formed with an open end 54 into which the aerosol-generating device 200 enters, the aerosol-generating device 100 further comprises a rotatable wheel 60 and a driving member 70, the driving member 70 comprising a rotatable shaft 71, the rotatable shaft 71 being coupled to the rotatable wheel 60, the rotation of the rotatable shaft 71 rotating the rotatable wheel 60. Meanwhile, the driven wheel 53 is arranged on the holding element 50, and the driven wheel 53 rotates to drive the holding element 50 to rotate, so that the aerosol product 200 is clamped by the rib 52 and is held in the first cavity 51, and a sufficient friction force exists between the aerosol product 200 and the rib 52, so that the aerosol product 200 can be driven to synchronously rotate when the holding element 50 rotates. The driven wheel 53 is provided with a gear 531, and the rotatable wheel 60 and the driven wheel 53 are in gear engagement transmission, so that when the driving element 70 drives the rotation shaft 71 to rotate, the rotation shaft 71 drives the rotatable wheel 60 to rotate, and the rotatable wheel 60 drives the driven wheel 53 to rotate, so that the aerosol product 200 is driven to rotate relative to the heating element 20, and tobacco in the aerosol product 200 can be effectively relieved from adhering to the heating element 20 under the effect of the relative rotation.

In some embodiments, the drive element 70 is a pneumatic or hydraulic cylinder or the like. In addition, the drive relationship between the rotatable wheel 60 and the retaining element 50 is not limited to a geared drive, and in some embodiments may be a chain drive, a worm gear, a swing link, a linkage, or a pulley drive. In a specific embodiment, as shown in fig. 5, the rotatable wheel 60 and the driven wheel 53 are both pulleys, and a driving belt 61 is disposed between the rotatable wheel 60 and the driven wheel 53, and the driving belt 61 may be a flexible belt, so that rotation of the rotatable wheel 60 may move the driving belt 61, and movement of the driving belt 61 may further rotate the driven wheel 53, thereby realizing transmission between the rotatable wheel 60 and the holding element 50.

With continued reference to fig. 3, the aerosol-generating device 100 has a proximal end 110 and a distal end 120 disposed opposite to each other along a length direction thereof, and the driving element 70 and the circuit board 30 are both extended along the length direction of the aerosol-generating device 100, so as to minimize the structural space occupied by the driving element 70 and the circuit board 30, thereby avoiding a large increase in the volume of the aerosol-generating device 100 due to the addition of the driving element 70 in the aerosol-generating device 100, since the volume of the aerosol-generating device 10 is generally designed to be smaller for a user to carry about.

In some embodiments, as shown in fig. 6, to facilitate the full use of the structural space, the circuit board 30 includes a first portion 31 and a second portion 32, the first portion 31 and the second portion 32 are electrically connected so that the first portion 31 and the second portion 32 communicate with each other, and the first portion 31 and the second portion 32 are disposed in different directions, that is, the first portion 31 and the second portion 32 are not on a complete circuit board. The first portion 31 and the second portion 32 are respectively provided with corresponding electronic components, and the circuit board 30 is split into the first portion 31 and the second portion 32, so that all electronic components can be integrated on one circuit board, the size of the circuit board is increased, and the structural design of other components is inconvenient.

In a further embodiment, to avoid high temperatures of the heating element 20 from being transferred to the electronic components of the circuit board 30, thereby affecting the reliability of the electronic components on the circuit board 30, the driving element 70 extends between the chamber 10 and the circuit board 30 to keep the circuit board 30 away from the chamber 10 as much as possible, preventing high temperatures of the heating element 20 in the chamber 10 from being transferred to the electronic components on the circuit board 30.

In some embodiments, the rotatable wheel 60 is provided at the proximal end of the aerosol-generating device 100 such that the rotational axis 71 of the drive element 70 extends into the drive rotation of the rotatable wheel 60. In addition, the provision of a rotatable wheel 60 at the proximal end of the aerosol-generating device 100 is also advantageous for a space-saving construction.

In a further embodiment, at least a portion of the proximal housing of the aerosol-generating device 100 is transparent, such that a user may directly observe through the transparent portion when the rotatable wheel 60 is rotated and/or when the driven wheel 53 on the holding element 50 is rotated, thereby enhancing the technical and cooling aspects of the aerosol-generating device 100.
