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, embodiments of the present application provide an aerosol-generating system 100 comprising an aerosol-generating article 200 and an aerosol-generating device 10; the aerosol-generating article 200 is removably inserted into the aerosol-generating device 10, the aerosol-generating device 10 being configured to heat at least part of the inserted aerosol-generating article 200 to generate an aerosol.
As shown in fig. 2-4, the aerosol-generating device 10 includes a first housing 10, an extractor 11, an outer cartridge 12, a holder 13, a heater 14, an inner cartridge 15, a base 16, a seal 17, a second housing 20, a cell 21, and a circuit board 22.
The first casing 10 and the second casing 20 are both substantially tubular, and an accommodating space is formed inside the first casing 10 and the second casing 20 after the first casing 10 and the second casing 20 are combined. The components such as the extractor 11, the outer cylinder 12, the holder 13, the heater 14, the inner cylinder 15, the base 16, the seal 17, the cell 21, and the circuit board 22 are housed in the housing space.
The battery cell 21 and the wiring board 22 are disposed in the second casing 20. The battery cell 21 is used for providing power; in a preferred embodiment, the cells 21 are rechargeable cells. The charging interface is arranged between the battery cell 21 and the lower end opening of the second casing. A circuit board 22 is arranged above the cells 21, the circuit board 22 being fixable to a support (not shown in the drawings), the circuit board 22 being used for overall control of the aerosol-generating device 10. The keys are electrically connected with the circuit board 22 and exposed outside the second casing 20 through the second casing 20.
A chamber a for removably receiving an aerosol-generating article 200. The aerosol-generating article 200 may be inserted into the chamber a through an opening in the upper end of the first housing 10.
The heater 14 is for heating the aerosol-generating article 200 received in the chamber a to generate a smokable aerosol. In this example, the heater 14 is configured as a needle or sheet, the proximal end of which may pass through one end of the extractor 11 and be inserted into the aerosol-generating article 200 received in chamber a. The heater 14 includes a resistance heating element (not shown) to be coupled with the battery cell 21 to generate heat. In other examples, the heater 14 may be configured to be penetrated by a varying magnetic field to generate heat. In other examples, it is also possible that the heater 14 may be configured to heat around at least part of the periphery of the aerosol-generating article 200.
The inner cylinder 15 is open at the upper end and has a holding portion at the lower end. One end of the heater 14 is held in a holding portion of the lower end of the inner tube 15.
The base 16 is disposed below the inner cylinder 15 and detachably connected to the inner cylinder 15. The connection means includes, but is not limited to, a snap connection. The base 16 has an insulated cavity at least partially surrounding the holder; the heat insulation chamber can reduce the heat transfer to the outside, and prevent the temperature of the first casing 10 or the second casing 20 from being too high.
The holder 13 is sleeved outside the inner cylinder 15 and the base 16, one end of the holder 13 is held in the second housing 20, and the other end abuts against the outer cylinder 12. The outer cylinder 12 is fitted over the holder 13, and has one end held in the second housing 20 and the other end abutting against the extractor 11.
As will be understood in conjunction with fig. 6, the extractor 11 is configured in a tubular shape extending in the axial direction of the chamber a, the tubular shape of the extractor 11 being hollow to form the chamber a. The upper end 11a of the extractor 11 has an extension 11a1 extending radially toward the first housing 10. The extractor 11 is movable for extracting the aerosol-generating article 200 received in the chamber a; when the aerosol-generating article 200 is not extracted by the extractor 11, its lower end 11b projects into the inner barrel 15, and the extension 11a1 of the extractor 11 is retained on the outer barrel 12. The lower end 11b of the extractor 11 has a through hole 11c, an extension 11d extending radially toward the through hole 11 c. When the aerosol-generating article 200 is received in chamber a, its bottom end remains on the extension 11d, and the heater 14 proximal end can be inserted through the through-hole 11c and into the aerosol-generating article 200 received in chamber a.
As will be appreciated in conjunction with fig. 5-8, the control circuitry facilitates control of the heating action of the heater 14 in order to detect whether the aerosol-generating article 200 is inserted into or removed from the chamber a. The aerosol-generating system 100 further comprises a first electrical connection 18, a second electrical connection 19, a conductive portion 23 and a detection circuit. It should be noted that the control circuit may be integrated in the circuit board 22, or it is also feasible to integrate it on another circuit board.
The first electrical connection 18, the second electrical connection 19 and the detection circuit are all provided within the aerosol-generating device 10; the electrically conductive portion 23 is disposed on the aerosol-generating article 22; the detection circuit is configured to sense an electrical connection status between the first electrical connector 18 and the second electrical connector 19 to generate an article insertion or removal signal. Wherein the electrical connection state comprises a first state and a second state; in the first state, the conductive portion 23 is electrically connected to both the first electrical connector 18 and the second electrical connector 19; in the second state, the conductive portion 23 is kept disconnected from both the first electrical connector 18 and the second electrical connector 19. It will be appreciated that in other examples it is also possible that the conductive portion 23 remains disconnected from the first electrical connector 18 or the second electrical connector 19, i.e. from at least one of the first electrical connector 18 and the second electrical connector 19.
In a particular implementation, the detection circuit is electrically connected to both the first electrical connection 18 and the second electrical connection 19; it is also possible that the detection circuit may be integrated in the circuit board 22 or on another circuit board.
The first electric connector 18 and the second electric connector 19 are arranged at intervals and adopt the same structural design. Taking as an example the first electrical connector 18, the first electrical connector 18 comprises a portion arranged inside the chamber a: a portion 18a extending axially within chamber a and a portion 18b extending radially within chamber a; the first electrical connection 18 also comprises a portion 18c extending radially outwards from the portion 18a towards the cavity a. Correspondingly, the inner wall of the extractor 11 is provided with an axially extending groove 11e, the extending part 11d is provided with a radially extending groove 11f, and the side wall is provided with a through hole 11 g. In this way, the portion 18a of the first electrical connector 18 is at least partially housed in the groove 11e, the portion 18b is at least partially housed in the groove 11f, and the portion 18c is electrically connected to the detection circuit after passing through the through hole 11 g. The second electrical connection 19 is similar to the first electrical connection 18 and will not be described in detail. In a further preferred implementation, the portions of the first electrical connector 18 and the second electrical connector 19 placed inside the chamber a are arranged axisymmetrically along the axial direction of the chamber a. In a further preferred embodiment, the first electrical connection 18 and the second electrical connection 19 are both arranged close to the bottom end of the chamber a.
The conductive portion 23 is at least partially exposed on an outer surface of the aerosol-generating article 200. In particular, the aerosol-generating article 200 comprises a filter segment 201, an aerosol-generating segment 202 having smokable material; the electrically conductive portion 23 is arranged on the aerosol-generating segment 202. The electrically conductive portion 23 is disposed proximate an upstream end (i.e., the lower end as shown) of the aerosol-generating segment 202.
The conductive portion 23 may be a conductive coating formed on the outer surface of the aerosol-generating article 200 or a conductive member at least partially exposed on the outer surface of the aerosol-generating article 200. The conductive portion 23 extends along a circumferential direction of the aerosol-generating article 200. In a preferred embodiment, the ratio of the circumferential extension of the conductive portion 23 to the circumferential length of the aerosol-generating article 200 is greater than 0.5 and equal to or less than 1. In the present example, the conductive portion 23 has a ring shape.
In this way, the detection circuit forms an open circuit through the first electrical connector 18 and the second electrical connector 19 when the aerosol-generating article 200 is not inserted in the chamber a.
When the aerosol-generating article 200 is inserted into the chamber a through the opening in the upper end of the first housing 10, the conductive portion 23 is in contact with the portion 18a of the first electrical connector 18 and the axially extending portion of the second electrical connector 19 to form an electrical connection, such that the detection circuit forms a pathway through the conductive portion 23, the first electrical connector 18 and the second electrical connector 19; at this point, the detection circuit may generate an article insertion signal, such as: a high level signal; the control circuit can control the heater 14 to automatically start heating after receiving the high level signal. When the aerosol-generating article 200 is removed from chamber a, the process is reversed.
As will be appreciated in conjunction with fig. 9-12, in another example, unlike the example of fig. 5-8, the first electrical connection 180, the second electrical connection 190, the electrically conductive portion 230 and the detection circuit are all provided within the aerosol-generating device 10. It should be noted that the structural components not shown in fig. 9-12 can be understood with reference to fig. 5-8.
In particular, first electrical connection 180 and second electrical connection 190 are arranged outside extractor 110, i.e. physically separated from chamber a; in a preferred implementation, the first electrical connector 180 and the second electrical connector 190 are arranged on the inner wall of the inner barrel 150 and both extend in an axial direction parallel to the chamber a; the structure of the inner barrel 150 is similar to that of the inner barrel 15 described above. The detection circuit is electrically connected to both the first electrical connection 180 and the second electrical connection 190.
The conductive portions 230 are arranged along the circumferential direction of the chamber a; preferably, the circumferential length of the conductive portion 230 is greater than one-half of the circumferential length of the extractor 110; preferably, the conductive portion 230 is disposed near or at the bottom end of the chamber a. The side wall of the extractor 110 has a groove 110a and a through hole 110b, and other structural parts can refer to the extractor 11 described above. The conductive portion 230 is a symmetrical structure including: a portion 230a retained within groove 110a (i.e., retained on the outer sidewall of extractor 110), a portion 230b disposed within chamber a (i.e., protruding on the inner sidewall of extractor 110), a portion 230c extending within through-hole 110b, and a portion 230d disposed outside extractor 11 (i.e., protruding on the outer sidewall of extractor 110). Portion 230c is used to connect portion 230a and portion 230b, and portion 230b and portion 230 d. Portions 230a, 230b and 230c are resilient; the portion 230d is held stationary or less resilient than the other portions. Portions 230b and 230d are generally arcuate, with the arcuate of portion 230b being curved outwardly of chamber a and the arcuate of portion 230d being curved inwardly of chamber a.
In this way, when the aerosol-generating article 200 is not inserted into the chamber a, the conductive portion 230 remains disconnected from the first and second electrical connectors 180, 190, i.e. the detection circuit forms an open circuit through the first and second electrical connectors 180, 190.
When the aerosol-generating article 200 is inserted into the chamber a through the opening in the upper end of the first housing 10, the aerosol-generating article 200 comes into contact with the portion 230b of the conductive portion 230 disposed within the chamber a, triggering the conductive portion 230 to become active with respect to the first electrical connector 180 and the second electrical connector 190. Specifically, the aerosol-generating article 200 presses the portion 230b of the conductive portion 230 disposed in the chamber a, so that the portion 230b moves toward the outside of the through hole 110b, and further, the portion 230d disposed outside the extractor 11 moves toward the inner wall of the inner barrel 150, so that the portion 230d is in contact with the first electrical connector 180 and the second electrical connector 190 to form an electrical connection. Finally, the detection circuit is made to form a passage through the conductive part 230, the first electrical connector 180 and the second electrical connector 190; at this point, the detection circuit may generate an article insertion signal, such as: a high level signal; the control circuit can control the heater 14 to automatically start heating after receiving the high level signal. When the aerosol-generating article 200 is removed from chamber a, the reverse is true; the resilient portion of the conductive portion 230 may ensure that the conductive portion 230 returns to the initial position.
It is readily envisaged that adjustments may be made based on the structural examples of figures 9-12, such that when the aerosol-generating article 200 is not inserted into the chamber a, the conductive portion 230 remains in contact with the first electrical connector 180 and the second electrical connector 190; it is also possible that the electrically conductive portion 230 remains disconnected from the first electrical connector 180 and the second electrical connector 190 when the aerosol-generating article 200 is inserted into the chamber a.
As will be appreciated in conjunction with fig. 13-16, in a further example, unlike the example of fig. 5-8, the first electrical connection 1800, the second electrical connection 1900, the conductive portion 2300 and the detection circuit are all provided within the aerosol-generating device 10. It should be noted that the structural components not shown in fig. 13-16 can be understood with reference to fig. 5-8.
The extractor 1100 has a bottom wall 1100a, a side wall 1100B and an extension 1100c extending radially outward of the chamber a, the extension 1100c having a receiving chamber B. The conductive portion 2300 is provided on the outer surface of the extractor 1100, and has a shape matching the outer surface shape of the extractor 1100; specifically, the conductive portion 2300 is a symmetrical structure including a portion 2300a held on the bottom wall 1100a of the extractor 1100, a portion 2300B held on the outer side wall 1100B of the extractor 1100, a portion 2300c held in the housing chamber B, and a portion 2300d held on the end wall of the extension 1100 c. An elastic member (2301, 2302 in the figure) is further provided in the housing chamber B, and one end of the elastic member is held in the housing chamber B (which may be held by a separate tubular member or a tubular member integrally formed with the extractor 1100), and the other end abuts against the portion 2300c of the conductive portion 2300.
The first electrical connector 1800, the second electrical connector 1900 and the conductive portion 2300 are disposed outside the extractor 1100 with a spacing therebetween. A magnetic component 1801 is connected to one end of the first electrical connector 1800, and another elastic component (not shown in the drawings) is fixed between the magnetic component 1801 and the first electrical connector 1800; a magnetic member 1901 is connected to one end of the second electrical connector 1900, and another elastic member (not shown) is fixed between the magnetic member 1901 and the second electrical connector 1900. The magnetic member 1801 is housed in the cavity 1200b of the outer cylinder 12, the magnetic member 1901 is housed in the cavity 1200a of the outer cylinder 12, and the first electrical connector 1800 and the second electrical connector 1900 are provided along the inner wall of the outer cylinder 12.
In this way, when the aerosol-generating article 200 is not inserted into or received in chamber a, the conductive portion 2300 remains disconnected from the first electrical connector 1800 and the second electrical connector 1900, i.e. the detection circuit forms an open circuit through the first electrical connector 1800 and the second electrical connector 1900.
When the aerosol-generating article 200 is inserted into or received in the chamber a through the opening in the upper end of the first housing 10, the bottom end of the aerosol-generating article 200 abuts the bottom wall 1100a of the extractor 1100, causing the extractor 1100 to move with the aerosol-generating article 200 in the article insertion direction, thereby bringing the conductive portions 2300 into motion in the article insertion direction. The magnetic elements 1801 and 1901 may remain magnetically connected with the portion 2300d of the conductive portion 2300 when the conductive portion 2300 is moved a predetermined distance along the article insertion direction; so that the first electrical connector 1800 is electrically connected to the conductive portion 2300 via the magnetic member 1801, and the second electrical connector 1900 is electrically connected to the conductive portion 2300 via the magnetic member 1901; eventually allowing the detection circuit to be routed through conductive portion 2300, first electrical connector 1800, and second electrical connector 1900; at this point, the detection circuit may generate an article insertion signal, such as: a high level signal; the control circuit can control the heater 14 to automatically start heating after receiving the high level signal. When the aerosol-generating article 200 is removed from chamber a, the reverse is true; the resilient members (2301, 2302 in the figures) ensure that the conductive portion 2300 and the extractor 1100 can be returned to the initial position together.
It is readily envisaged that adjustments may be made based on the structural examples of figures 13-16 such that the conductive portion 2300 remains in contact with the first electrical connector 1800 and the second electrical connector 1900 when the aerosol-generating article 200 is not inserted into chamber a; it is also possible that the conductive portion 2300 remains disconnected from the first electrical connector 1800 and the second electrical connector 1900 when the aerosol-generating article 200 is inserted into chamber a.
It is also possible to adjust based on the structural examples of fig. 13-16 such that the conductive portion 2300 is movable with the aerosol-generating article 200 along the article insertion direction, while the extractor 1100 is not movable with the aerosol-generating article 200 along the article insertion direction.
Further embodiments of the present application provide a method of detecting a use state of an aerosol-generating article, to which reference is made.
The method comprises the following steps:
sensing an electrical connection state between the first electrical connection (18, 180, 1800) and the second electrical connection (19, 190, 1900);
generating an article insertion or removal signal according to the electrical connection state;
wherein the electrical connection state comprises a first state and a second state; in the first state, the conductive portion (23, 230, 2300) is electrically connected to both the first electrical connector (18, 180, 1800) and the second electrical connector (19, 190, 1900); in the second state, the conductive portion (23, 230, 2300) remains disconnected from at least one of the first electrical connector (18, 180, 1800) and the second electrical connector (19, 190, 1900).
