An "aerosol-generating article" according to embodiments of the present invention refers to a product, such as a cigarette, cartridge or rod, preferably a disposable article, containing a smoking material, capable of generating an aerosol, such as smoke or a mist, upon heating. The aerosol-generating article is not capable of providing electrical energy by itself.

An "aerosol-generating device" as described in embodiments of the present invention refers to a device, such as a smoking article, for providing electrical energy to an aerosol-generating article.

Referring to fig. 1 to 4, an aerosol-generating device 100 for heating an aerosol-generating article 200 to generate an aerosol for consumption by a user is provided. Embodiments of the present invention provide an aerosol-generating device 100, which includes a housing 110, a heater assembly 120, and a pushing mechanism 130, wherein the housing 110 is used to receive an aerosol-generating article 200, a heat-generating portion 121 of the heater assembly 120 extends into a receiving cavity 111 of the housing 110 during use, the aerosol-generating article 200 can be heated to generate aerosol when inserted into the receiving cavity 111 of the housing 110, the heater assembly 120 is withdrawn from the receiving cavity 111 by using the pushing mechanism 130 after heating is completed, and the aerosol-generating article 200 is still placed in the receiving cavity 111, so that the heater 121 is separated from the aerosol-generating article 200, adhesion between the heater 121 and a heated aerosol-generating substance is avoided, and the aerosol-generating article 200 is convenient to remove.

In the aerosol-generating device 100 provided in the embodiment of the present invention, the housing 110 is provided with an accommodating cavity 111 for accommodating the aerosol-generating article 200; in an embodiment, the housing 110 has an opening 112 in communication with the receiving cavity 111 for insertion of the aerosol-generating article 200 from the opening 112 into the receiving cavity 111. The wall of the housing 110 defining the receiving cavity 111 may include a side wall 113 and a bottom wall 114, which are connected to each other to form a cup-shaped structure for defining the receiving cavity 111. Preferably, the shape of the receiving cavity 111 is adapted to the shape of the aerosol-generating article 200 so that the aerosol-generating article 200 is not easily carried out by the mouth when inserted into the receiving cavity 111, nor is the aerosol-generating article 200 squeezed to cause excessive deformation to increase the resistance to draw.

In the aerosol-generating device 100 according to an embodiment of the present invention, the heater assembly 120 includes a heater 121 and a base 122 for fixing the heater 121, and the base 122 may fix the heater 121 by embedding, clamping, or the like, or may be integrally molded, for example, by injection molding or ceramic sintering. The heater 121 is for insertion into an aerosol-generating article 200 to heat an aerosol-generating substance therein to generate an aerosol; the heater 121 comprises one or more electrical heating elements, preferably of electrically resistive material, which when energised convert electrical energy into heat energy to generate heat to enable the aerosol-generating substance to be heated to generate an aerosol, the electrical heating elements preferably being combined with an insulating material such as ceramic to form a strong needle, rod or sheet shaped heater 121 for at least partial insertion into the aerosol-generating substance of the aerosol-generating article 200.

Embodiments of the present invention provide an aerosol-generating device 100 in which the pushing mechanism 130 is movably coupled to the heater assembly 120, pushing the heater assembly 120 to slide between a position extending into the receiving cavity 111 and a position exiting away from the receiving cavity 111. The urging means 130 is adapted to urge the heater assembly 120 to slide under the influence of an external force between a heating position in which the heater 121 is fully inserted into the aerosol-generating article 200 and a disengaged position in which the heater 121 extends into the receiving cavity 111 at its deepest extent, in which case the receiving cavity 111 may be heated to generate an aerosol if the aerosol-generating article 200 is received therein; the separation position is a position in which the heater 121 has fully exited the receiving cavity 111, and for the furthest position in which the heater 121 has exited away from the receiving cavity 111, the heater 121 is no longer in contact with the aerosol-generating article 200 within the receiving cavity 111. As the heater assembly 120 is urged to slide between the heating position to the separating position after the aerosol-generating article 200 has been heated, the heater 121 is gradually withdrawn from the receiving cavity 111, effecting separation of the heater 121 from the aerosol-generating article 200.

Preferably, the heating position is a position in which the heater 121 heats the aerosol-generating article 200, and when the heater assembly 120 is in this position, waiting for the aerosol-generating article 200 to be inserted into the receiving cavity 111, or having the aerosol-generating article 200 inserted into the receiving cavity 111 waiting to be heated or being heated, this position may also be referred to as the working position. The separation position is a position in which the heater 121 is fully separated from the aerosol-generating article 200, and when the heater assembly 120 is in this position, indicating that the heater 121 has been fully separated from the aerosol-generating article 200, the aerosol-generating article 200 may be removed directly. When the heated aerosol-generating article 200 is removed, the heater assembly 120 needs to be pushed back into position to extend into the receiving cavity 111, awaiting the next operation.

In one embodiment, the pushing mechanism 130 includes a push button 131, and the push button 131 is movably coupled to the housing 110. For example, the push button 131 may slide along the housing 110, and for convenience of description, the direction in which the heater assembly 120 moves toward the opening 112 is referred to as a first direction 141, and the direction in which the heater assembly 120 exits from the receiving cavity 111 is referred to as a second direction 142, and it is apparent that the first direction 141 is also the direction in which the heater assembly 120 moves from the separated position to the heating position, as the receiving cavity 111 is fixed relative to the housing 110, in the form that the heater assembly 120 is pushed upward, that is, the heater assembly 120 is pushed toward the aerosol-generating article 200; the second direction 142 is also the direction of movement of the heater assembly 120 from the heating position to the detached position, as evidenced by the heater assembly 120 being backed, i.e., the heater assembly 120 being moved away from the aerosol-generating article 200. The portion of the push button 131 outside the housing 110 may be designed to facilitate finger force, and may be provided with protrusions or lines to increase the friction force when the push button 131 is operated.

Preferably, the housing 110 is provided with a sliding slot 115 for limiting the push button 131, the push button 131 can slide along the sliding slot 115 under the action of an external force, for example, the sliding slot 115 is in a straight shape, the opening direction of the straight shape is parallel to both the first direction 141 and the second direction 142, and the heater assembly 120 is driven to move when the push button 131 slides in the sliding slot 115. The position of the push button 131 in the sliding slot 115 corresponds to the position of the heater assembly 120, for example, the push button 131 moves to the first position 116 of the sliding slot 115, and pulls the heater assembly 120 to move to the position extending into the accommodating cavity 111; the push button 131 moves to the second position 117 of the slide slot 115, drawing the heater assembly 120 to move out of the position away from the receiving cavity 111.

In an embodiment, the moving direction of the push button 131 is the same as the moving direction of the heater assembly 120, for example, the push mechanism 130 may be directly and fixedly connected to the heater assembly 120 (not shown in the figure), the first position 116 and the second position 117 of the chute 115 may be two ends of the linear chute 115, respectively, and the push button 131 moves from the bottom end to the top end of the chute 115, that is, the push button 131 is pushed along the first direction 141 to drive the heater assembly 120 to move from the separated position to the heating position; the push button 131 moves from the top end to the bottom end of the sliding chute 115, i.e., the push button 131 is pushed in the second direction 142, so as to move the heater assembly 120 from the heating position to the separating position.

In one embodiment, the pushing mechanism 130 further includes a gear 132 for coupling the base 122 and the push button 131, such that the base 122 and the push button 131 are movably coupled, and the transmission of the pushing force can be achieved without completely coinciding the two moving directions, for example, the moving direction of the push button 131 is opposite to the moving direction of the heater assembly 120. The first position 116 and the second position 117 of the sliding chute 115 may be two ends of a linear sliding chute 115, respectively, and the push button 131 moves from the bottom end to the top end of the sliding chute 115, that is, the push button 131 is pushed along the first direction 141 to drive the heater assembly 120 to move from the heating position to the separation position; the push button 131 moves from the top end to the bottom end of the sliding chute 115, i.e., the push button 131 is pushed in the second direction 142, which brings the heater assembly 120 to move from the separated position to the heating position. Preferably, the gear 132 includes a threaded opening, an external thread is disposed on the base 122, an external thread is disposed on the push button 131, the gear 132 is engaged with the external threads on the base 122 and the push button 131, respectively, the external threads on the base 122 and the external threads on the push button 131 are substantially parallel, the gear 132 is clamped therein, and the pushing force of the push button 131 is transmitted to the heater assembly 120 through the gear 132 and the two moving directions are reversed. It should be particularly noted that the chute 115 may be shaped as an arc, a spiral, etc. and the heater assembly 120 may be moved in the first direction 141 and the second direction 142 by providing a combination of transmission members to form different gears 132 to transmit the thrust. The first elastic member 133 is further disposed in the housing 110, and pushes the heater assembly 120 to move in the first direction 141, that is, when the push button 131 moves in the first direction 141, the heater assembly 120 moves in the second direction 142, and at this time, the first elastic member 133 is compressed, and when the finger pushing the push button 131 is released, the heater assembly 120 moves from the separated position to the heating position, that is, moves in the first direction 141, under the pushing force of the first elastic member 133. To avoid that the heater assembly 120 is pushed to move in the second direction 142 when the aerosol-generating article 200 is inserted into the receiving cavity 111, the push button 131 is preferably provided with a detent (not shown) that is disengaged only when the push button 131 is pressed, and the push button 131 is restrained when no pressing is present, thereby restraining the heater assembly 120 so that it cannot be pushed out of the receiving cavity 111 by an inserted cigarette.

In an embodiment, the walls of the housing 110 defining the receiving cavity 111 comprise a side wall 113 and a bottom wall 114, which are connected to form a cup-shaped structure, the bottom wall 114 being provided with apertures 118 for allowing the insertion of a heater 121 into the aerosol-generating article 200 received in the receiving cavity 111. The aerosol-generating article 200 further comprises a filter 210 disposed at the gas outflow end of the aerosol-generating article 200, opposite to the gas inflow end, which also becomes the gas inflow end. When the aerosol-generating article 200 is disposed in the receiving cavity 111 of the aerosol-generating device 100, the filter 210 may be exposed from the opening 112 for inhalation by a user, with the gas inflow end abutting the bottom wall 114, thereby opening the aperture 118 in the bottom wall 114 and allowing air to flow into the aerosol-generating article 200. As the user draws, the heater 121 heats the aerosol generating substance to form an aerosol containing aerosol. The aerosol is then carried in an air flow to the mouth of the user. As air flows through and adjacent to the aerosol-generating substance, the air flows through the open holes 118 in the bottom wall 114, the size and shape of the holes 118 being operable to manage the air flow and hence the characteristics of the aerosol.

Referring to fig. 5 to 7, based on the foregoing embodiments, the aerosol-generating device 100 according to the present invention may further include an extraction component 150, where the extraction component 150 is configured to assist in pushing the aerosol-generating article 200 out of the accommodating cavity 111 after the heater component 120 is withdrawn away from the accommodating cavity 111, and preferably, the pushing mechanism 130 triggers the extraction component 150 after pushing the heater component 120 to the position withdrawn away from the accommodating cavity 111, and the extraction component 150 pushes the aerosol-generating article 200 to move along the length direction of the accommodating cavity 111, that is, along the first direction 141, and directly eject it or push it for a distance for the user to take it out.

The extraction assembly 150 is configured to assist in disengaging the aerosol-generating article 200 from the receiving cavity 111, and preferably, the extraction assembly 150 comprises a shoe 151 abutting against the air inlet end of the aerosol-generating article 200, a movable catch 152 detachably connected to the shoe 151, and a second resilient member 153 for pulling the shoe 151 to move in a direction away from the bottom of the receiving cavity 111, wherein the shoe 151 is movable along the length of the receiving cavity 111, and the length of the receiving cavity 111 is the direction of extension between the bottom of the receiving cavity 111 and the opening 112, and is also the direction of insertion and removal of the aerosol-generating article 200 from the receiving cavity 111. For example, the second elastic element 153 is a tension spring, one end of the second elastic element is connected to the opening 112 of the accommodating cavity 111, the other end of the second elastic element is connected to the bottom support 151, and the tension force is provided to pull the bottom support 151 to move towards the opening 112, so that the bottom support 151 moves towards the opening 112 to support the aerosol-generating article 200 away from the accommodating cavity 111 for the purpose of assisting detachment. When the auxiliary aerosol-generating article 200 is inserted into the receiving cavity 111, the aerosol-generating article 200 and the shoe 151 are pushed together by external force to the bottom of the receiving cavity 111, thereby causing the shoe 151 to engage with the movable catch 152, such that the shoe 151 cannot "return", i.e. the shoe 151 cannot move in the direction of the opening 112, until triggered by the pushing mechanism 130 to disengage the shoe 151 from the movable catch 152.

Preferably, the movable hook 152 limits the bottom support 151 at the bottom of the accommodating cavity 111, and when the pushing mechanism 130 pushes the heater assembly 120 to exit from the accommodating cavity 111, the pushing mechanism 130 pulls the movable hook 152 to separate from the bottom support 151.

Preferably, the movable hanging buckle 152 can move along a direction perpendicular to the length direction of the accommodating cavity 111, the length direction of the accommodating cavity 111 is also the extending direction of the heater 121, when the movable hanging buckle 152 is close to the accommodating cavity 111, the bottom support 151 is limited at the bottom of the accommodating cavity 111, and when the movable hanging buckle 152 is far from the accommodating cavity 111, the movable hanging buckle 152 is separated from the bottom support 151.

Preferably, the extracting component 150 further includes a first magnet 154 disposed on the movable hook 152, a second magnet 155 disposed on the pushing mechanism 130 and repelling the first magnet 154, and a third magnet 156 disposed on the pushing mechanism 130 and attracting the first magnet 154. For example, the pushing mechanism 130 includes a push button 131 movably coupled to the housing 110, the push button 131 is disposed outside the housing 110 and extends along the length of the housing 110, the third magnet 156 attracts the first magnet 154 to make the first magnet 154 away from the accommodating cavity 111, so that the movable hook 152 is separated from the bottom bracket 151, and the second magnet 155 repels the first magnet 154 to make the first magnet 154 close to the accommodating cavity 111, so that the movable hook 152 is engaged with the bottom bracket 151. The first magnet 154 magnetically interacts with the second magnet 155 and the third magnet 156 at different times due to the sliding of the pushing mechanism 130 between different positions, for example, when the pushing mechanism 130 pushes the heater assembly 120 to a position withdrawn from the receiving cavity 111 (see fig. 7), the third magnet 156 attracts the first magnet 154, pulling the movable catch 152 away from the shoe 151; when the pushing mechanism 130 pushes the heater assembly 120 to a position extending into the receiving cavity 111 (see fig. 6), the second magnet 155 is repelled from the first magnet 154, so as to facilitate the movable hook 152 to be fastened with the bottom bracket 151.

Referring to fig. 8 to 11, in the aerosol-generating device 100 according to the embodiment of the present invention, the pushing mechanism 130 includes a knob 134, and the knob 134 is movably coupled to the housing 110. The rotation of knob 134 along housing 110 pushes heater assembly 120 to slide between a position extending into cavity 111 and a position withdrawn away from cavity 111. For example, the base 122 may have an outer thread on its outer circumference, the knob 134 may have a cylindrical shape with an inner thread on its inner circumference, and the outer thread on the base 122 may be engaged with the inner thread on the knob 134. The knob 134 disposed on the outer periphery of the housing 110 may be designed to facilitate finger force, and may be provided with a protrusion or a texture to increase the friction force when the knob 134 is operated. In this embodiment, except for the different pushing action of the knob 134 on the heater assembly 120, the movement of other structures is the same as that of the previous embodiment, and will not be described herein again.

It should be particularly noted that the pushing mechanism 130 according to the present invention is not limited to the above-mentioned embodiments, and the driving force may be provided in other forms, for example, other forms of pushing mechanisms 130 including, but not limited to, an electric motor, a pneumatic pump, a hydraulic pump, an electromagnet, etc. to push the heater assembly 120 to slide between the position of extending into the accommodating cavity 111 and the position of withdrawing away from the accommodating cavity 111, which all fall within the protection scope of the present invention.
