The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-8, an aerosol-generating device 100 according to an embodiment of the present disclosure includes a housing 10, a slider 20, a sleeve 30, a connector 40, a heater 50, a base 60, and a power supply assembly 70.

The housing 10 has an insertion opening 11 in a top wall thereof, through which insertion opening 11 the aerosol-generating article is removably received or inserted in the heating chamber. When assembled, the housing 10 is flush with the housing 71 of the power supply assembly 70 to maintain a clean and consistent appearance, the housing 10 and the housing 71 together defining or forming a housing or casing of the aerosol-generating device 100.

One end of the connector 40 extends into the housing 71 and the other end extends into the housing 10. The connector 40 has a receiving cavity in which the lower end of the sleeve 30 is received. In other examples, it is also possible that the connector 40 is integrally formed with the housing 71.

As will be understood from fig. 8, the sleeve 30 includes an outer cylinder 31 and an inner cylinder 32 which are spaced apart from each other, and a connecting portion 33 which connects an upper end of the outer cylinder 31 and an upper end of the inner cylinder 32. The lower end of the outer cylinder 31 is held in the receiving cavity of the joint 40. The inner barrel 32 defines or forms a heating chamber of the aerosol-generating device 100.

The heater 50 is used to heat smokable material in the aerosol-generating article to generate a smokable aerosol. The heater 50 may be configured as a needle or a sheet, and the upper end of the heater 50 may be inserted through the lower end of the inner cartridge 32 and into the aerosol-generating article received in the heating chamber, with the lower end of the heater 50 being retained in the base 60.

In the example of fig. 1-8, heater 50 includes a resistive heating element (not shown) that is electrically connected to electrical core 72. The heater 50 is formed separately from the base 60, the base 60 has a fixing hole, and the lower end of the heater 50 is held in the fixing hole of the base 60 and fixed by welding, gluing, or the like. In other examples, it is also possible that the heater 50 is integrally formed with the base 60. In other examples, the heater 50 may employ electromagnetic induction heating, infrared radiation heating, or other heating means, as is also possible. In other examples, the heater 50 may also be configured to extend in an axial direction of the heating chamber and at least partially surround the heating chamber; in this way, the heater 50 may heat around the periphery of the aerosol-generating article, so-called circumferential heating or peripheral heating.

As can be seen from fig. 4, when the lower end of the outer tube 31 is housed in the housing cavity of the joint 40, the gaps between the outer tube 31, the inner tube 30, and the joint 40 form a substantially sealed chamber. Insulation may be provided within the sealed chamber, for example: an aerogel; the sealed chamber may also be filled with a gas having a low thermal conductivity or evacuated to reduce the transfer of heat from the heater 50 to the housing 10.

The power module 70 includes a substantially tubular case 71, a battery 72 disposed in the case 71, and a circuit board 73.

The battery cell 72 is used for providing power; in a preferred implementation, the cells 72 are rechargeable cells.

The circuit board 73 is used for overall control of the aerosol-generating device 100. Various components are integrated on the circuit board 73 to realize functions such as overall control and charging management.

In order to be able to open or close the insertion opening 11, the aerosol-generating device 100 further comprises a first movable lid 12 and a second movable lid 13, which are symmetrically arranged within the housing 10. It should be noted that in other examples, it is also possible to provide only one movable cover.

As shown in fig. 6, the first movable cover 12 includes a cover plate 121, a latch hole 122, a boss 123 and a boss 124, the latch hole 122 is disposed on a left side wall of the cover plate 121, and the boss 123 and the boss 124 are disposed on front and rear side walls of the cover plate 121 and are disposed near a right side wall of the cover plate 121; the second movable cover 13 is similar in construction to the first movable cover 12. The housing 10 has a latch (not shown) on an inner surface of a top wall thereof, and the latch hole 122 and the latch hole of the second movable cover 13 are movably coupled to the latch.

The slider 20 is disposed between the insertion port 11 and the heating chamber. As will be understood with reference to fig. 7, the slider 20 is retained on the connecting portion 33 of the sleeve 30, the slider 20 comprises a generally annular body 21, a chute 22 and a chute 23 provided on the body 21, the chute 22 and the chute 23 both extending in the width direction of the aerosol-generating device 100, the chute 22 and the chute 23 being arranged in series in the thickness direction of the aerosol-generating device 100; the posts 123 and 124 are also arranged in sequence along the thickness direction of the aerosol-generating device 100; thus, the protruding column 123 and one protruding column of the second movable cover 13 are both connected in the sliding slot 22, and the protruding column 124 and the other protruding column of the second movable cover 13 are both connected in the sliding slot 23. Further, the connecting portion 33 is provided with a groove, the magnetic member 31 is received in the groove, another magnetic member may be provided on the body 21 or the body 21 itself has magnetism; the slider 20 is thus held on the sleeve 30 by the magnetic attraction between the magnetic member 31 and the other magnetic member (or the body 21).

The housing 10 may be movable up and down relative to the housing 71 or along the longitudinal direction of the aerosol-generating device 100.

As shown in fig. 1, in the initial state, the housing 10 is not movable with respect to the housing 71, and the first movable cover 12 and the second movable cover 13 are together in a position to close the insertion port 11.

As will be understood in conjunction with fig. 2-3, when the housing 10 moves upward relative to the housing 71 (the user can move upward by holding the housing 10 with fingers), the first movable cover 12 and the second movable cover 13 are driven to move together along the sliding track defined by the sliding groove; wherein, the protruding column 123 moves leftwards along the sliding slot 22, and the protruding column 124 moves leftwards along the sliding slot 23; one convex column of the second movable cover 13 moves to the right along the sliding slot 22, and the other convex column of the second movable cover 13 moves to the right along the sliding slot 23. Thus, when the housing 10 is moved upward to the first position relative to the housing 71, the first movable cover 12 and the second movable cover 13 are moved together to a position where the insertion port 11 is opened; at this point, the aerosol-generating article may be inserted into the heating chamber through the insertion opening 11 and the heater 50 activated to begin heating.

Subsequently, when the housing 10 moves downward relative to the housing 71, the protruding column 123 moves rightward along the sliding slot 22, and the protruding column 124 moves rightward along the sliding slot 23; one convex column of the second movable cover 13 moves leftwards along the sliding slot 22, and the other convex column of the second movable cover 13 moves leftwards along the sliding slot 23. Thus, when the housing 10 is moved downward to the second position with respect to the housing 71 or the housing 10 is returned to the initial state, the first movable cover 12 and the second movable cover 13 are moved together or returned to the position of closing the insertion port 11.

Further, the connector 40 exposed outside the housing 71 may be provided with an indication device 41, for example: an LED lamp. In the initial state or when the housing 10 moves downward to the second position relative to the housing 71, the indicating device 41 is hidden in the housing 10; when the housing 10 is moved upwards to a first position relative to the housing 71, the indication means 41 is exposed, and the user can obtain information about the indication given by the aerosol-generating device 100 through the indication means 41, for example: indication of completion of preheating of the aerosol-generating article, charge information of the cells 72, etc.

Fig. 9-11 illustrate an aerosol-generating device 100 according to another embodiment of the present disclosure, in which a thermal insulator 80 is further disposed between the housing 10 and the sleeve 30, unlike the example of fig. 1-8. The heat insulation member 80 may be made of plastic material to prevent the high heat of the heater 50 from being transferred to the housing 10.

The heat insulator 80 is substantially cylindrical. The heat insulating member 80 is sleeved outside the outer cylinder 31, and the end of the lower end of the heat insulating member 80 abuts against the end of the upper end of the connecting member 40. The outer surface of the thermal insulation member 80 abuts against the inner surface of the casing 10 and may be joined together by an adhesive material. Thus, the heat insulator 80 can move together with the housing 10 when the housing 10 moves up and down with respect to the housing 71.

Further, the inner surface of the heat insulating member 80 has ribs 80a, and the ribs 80a protrude from the inner surface of the heat insulating member 80. The preferred rib 80a extends along the longitudinal direction of the aerosol-generating device 100 and is strip-shaped; of course, the rib 80a may have other shapes, such as a spiral shape, an arc shape, a ring shape, and the like. The number of the ribs 80a is not limited, and preferably, four ribs 80a may be provided at intervals along the circumferential direction of the heat insulating material 80. The raised height of the ribs 80a may be non-uniform along the longitudinal direction of the aerosol-generating device 100; for example: the height of the rib 80a near the upper and lower ends of the heat insulating member 80 may be smaller, and the height of the rib 80a in the middle may be larger. Thus, when the heat insulator 80 moves upward together with the housing 10 to the first position with respect to the housing 71, the rib 80a abuts against the outer surface of the outer cylinder 31, and the heat insulator 80 can be held in the first position together with the housing 10 without falling down. When the heat insulating member 80 moves downward together with the housing 10 to the second position with respect to the housing 71, the portions of the rib portions 80a close to the upper and lower openings of the heat insulating member 80 facilitate the movement of the heat insulating member 80 together with the housing 10 from the first position to the second position due to the small height of the projections.

It should be noted that the inner surface of the heat insulation member 80 may be provided with other holding members similar to the ribs 80a, so that the heat insulation member 80 and the housing 10 can be held together in the first position; for example: tabs or the like provided on the inner surface of the insulation member 80.

It should also be noted that it is also possible that the thermal insulation member 80 is formed integrally with the housing 10. Alternatively, it is also possible to not provide the thermal insulation 80 and to achieve that the housing 10 is held in the first position by ribs or other similar holding means provided on the inner surface of the housing 10 cooperating with the outer cylinder 31 or the connecting member 40.

It should also be noted that ribs or other similar retaining elements may also be provided on the outer surface of the outer cylinder 31 or the connecting element 40.

It should also be noted that in the example of fig. 1-8 or the example of fig. 9-11, the operation steps of the housing 10 may be combined with the operation steps of the heater 50, which is beneficial to simplify the operation of the aerosol-generating device 100 and improve the user experience. For example: when the housing 10 moves upward to the first position relative to the housing 71, the heater 50 may be immediately activated to preheat, so as to raise the temperature of the heater 50 (for example, to control the heater 50 to raise to the maximum working temperature or the preset temperature value below the target temperature with a smaller power); in this way, the heater 50 can be immediately controlled to warm up from a preset temperature value to a maximum operating or target temperature when the aerosol-generating article is placed in the heating chamber. When the housing 10 moves downward to the second position relative to the housing 71, the heater 50 is immediately controlled to stop heating.

It should be noted that the preferred embodiments of the present application are set forth in the description of the present application and the accompanying drawings, but the present application may be embodied in many different forms and is not limited to the embodiments described in the present application, which are not intended as additional limitations to the present application, which are provided for the purpose of making the present disclosure more comprehensive. Moreover, the above-mentioned technical features are combined with each other to form various embodiments which are not listed above, and all the embodiments are regarded as the scope described in the present specification; further, modifications and variations may occur to those skilled in the art in light of the foregoing description, and it is intended to cover all such modifications and variations as fall within the scope of the appended claims.
