Please understand with reference to FIGS. 5-8 , in order to detect whether the aerosol generating article 200 is inserted into or removed from the chamber A, it is convenient for the control circuit to control the heating action of the heater 14 . The aerosol generating system 100 also includes a first electrical connector 18 , a second electrical connector 19 , a conductive part 23 and a detection circuit. It should be noted that the control circuit can be integrated in the circuit board 22, or it is also feasible to integrate it in another circuit board.

The first electrical connector 18, the second electrical connector 19, and the detection circuit are all arranged in the aerosol generating device 300; the conductive part 23 is arranged on the aerosol generating product 200; the detection circuit is configured to sense The electrical connection status between the first electrical connector 18 and the second electrical connector 19 is used to generate a product insertion or removal signal.

In a specific implementation, the detection circuit is electrically connected to the first electrical connector 18 and the second electrical connector 19; the detection circuit can be integrated in the circuit board 22, or it is also feasible to integrate another circuit board of.

The first electrical connector 18 and the second electrical connector 19 are spaced apart and adopt the same structural design. Taking the first electrical connector 18 as an example, the first electrical connector 18 includes a portion disposed in the chamber A: a portion 18a extending axially in the chamber A and a portion 18b extending radially in the chamber A; An electrical connector 18 further includes a portion 18c extending radially outward from the portion 18a toward the chamber A. As shown in FIG. Correspondingly, the inner wall of the extractor 11 is provided with an axially extending groove 11e, the extension part 11d is provided with a radially extending groove 11f, and the side wall has a through hole 11g.

The conductive portion 23 is at least partially exposed on the outer surface of the aerosol generating article 200 . Specifically, the aerosol-generating product 200 includes a filter section 201 and an aerosol-generating section 202 with smokeable materials; the conductive part 23 is disposed on the aerosol-generating section 202 . The conductive part 23 is disposed close to the upstream end (ie, the lower end shown in the figure) of the aerosol generating section 202 .

The conductive part 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 part 23 extends along the circumferential direction of the aerosol generating article 200 .

In this example, the conductive portion 23 has a ring shape.

In this way, when the aerosol generating article 200 is not inserted into the chamber A, 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 inserted into the chamber A through the opening at the upper end of the first housing 10, the conductive portion 23 remains in contact with the portion 18a of the first electrical connector 18 and the axially extending portion of the second electrical connector 19. An electrical connection is formed, so that the detection circuit forms a path through the conductive part 23, the first electrical connector 18 and the second electrical connector 19; at this time, the detection circuit can generate a product insertion signal, for example: a high level signal; control After the circuit receives the high-level signal, it can control the heater 14 to automatically start heating. When the aerosol-generating article 200 is removed from chamber A, the above process is reversed.

Please understand in conjunction with FIG. 9-FIG. 12. In another example, different from the example in FIG. 5-FIG. It is installed in the aerosol generating device 300 . It should be noted that the structural components not shown in FIGS. 9-12 can be understood with reference to FIGS. 5-8 .

Specifically, the first electrical connector 180 and the second electrical connector 190 are arranged outside the extractor 110, that is, physically separated from the chamber A; in a preferred implementation, the first electrical connector 180 and the second electrical connector 190 They are arranged on the inner wall of the inner cylinder 150 and extend along the axial direction parallel to the chamber A; the structure of the inner cylinder 150 is similar to that of the aforementioned inner cylinder 15 . The detection circuit is electrically connected to both the first electrical connector 180 and the second electrical connector 190 .

The conductive part 230 is arranged along the circumferential direction of the chamber A; preferably, the circumferential length of the conductive part 230 is greater than 1/2 of the circumferential length of the extractor 110; preferably, the conductive part 230 is close to the chamber A The bottom end of the chamber A is set or set at the bottom end of the chamber A. The extractor 110 has a groove 110 a and a through hole 110 b on the side wall, and other structural parts can refer to the aforementioned extractor 11 . The conductive part 230 is a symmetrical structure, including: a part 230a held in the groove 110a (that is, kept on the outer wall of the extractor 110), a part 230b disposed in the chamber A (that is, protruded on the inner side of the extractor 110 wall), the portion 230c extending inside the through hole 110b, and the portion 230d disposed outside the extractor 11 (that is, protrudingly disposed on the outer wall of the extractor 110). Section 230c is used to connect section 230a and section 230b, and section 230b and section 230d.

The portion 230b and the portion 230d are generally arc-shaped, the arc of the portion 230b is curved toward the outside of the chamber A, and the arc of the portion 230d is curved toward the inside of the chamber A.

In this way, when the aerosol generating product 200 is not inserted into the chamber A, the conductive part 230 remains disconnected from the first electrical connector 180 and the second electrical connector 190, that is, the detection circuit passes through the first electrical connector 180 and the second electrical connector 190. The second electrical connection 190 forms an open circuit.

When the aerosol-generating product 200 is inserted into the chamber A through the opening at the upper end of the first casing 10, the aerosol-generating product 200 contacts the portion 230b of the conductive part 230 disposed in the chamber A, triggering the conductive part 230 to contact the first electrode. The connection part 180 and the second electrical connection part 190 are movable. Specifically, the aerosol generating product 200 squeezes the portion 230b of the conductive part 230 disposed in the chamber A, so that the portion 230b moves toward the outside of the through hole 110b, and then drives the portion 230d disposed outside the extractor 11 toward the inner wall of the inner cylinder 150 The direction of movement makes the portion 230d keep in contact with the first electrical connector 180 and the second electrical connector 190 to form an electrical connection. Finally, the detection circuit forms a path through the conductive part 230, the first electrical connector 180 and the second electrical connector 190; at this time, the detection circuit can generate a product insertion signal, for example: a high level signal; the control circuit receives the After the high level signal, the heater 14 can be controlled to start heating automatically. When the aerosol-generating article 200 is removed from the chamber A, the above process is reversed; the elastic part of the conductive part 230 can ensure that the conductive part 230 returns to its original position.

It can be easily conceived that adjustments can be made based on the structural examples in FIGS. It is also feasible that the conductive part 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.

Please understand in conjunction with FIG. 13-FIG. 16. In yet another example, different from the example shown in FIG. 5-FIG. It is installed in the aerosol generating device 300 . It should be noted that the structural components not shown in FIGS. 13-16 can be understood with reference to FIGS. 5-8 .

The extractor 1100 has a bottom wall 1100a, a side wall 1100b, and an extension portion 1100c radially extending toward the chamber A, and the extension portion 1100c has a receiving chamber B. The conductive part 2300 is arranged on the outer surface of the extractor 1100, and its shape matches the shape of the outer surface of the extractor 1100; specifically, the conductive part 2300 is a symmetrical structure, including a part held on the bottom wall 1100a of the extractor 1100 2300a, a portion 2300b held on the outer side wall 1100b of the extractor 1100, a portion 2300c held in the receiving chamber B, and a portion 2300d held on the end wall of the extension 1100c. An elastic piece (shown by 2301 and 2302 in the figure) is also arranged in the storage chamber B, and one end of the elastic piece is held in the storage chamber B (it can be held by a separate tubular part or a tubular part integrally formed with the extractor 1100), The other end is in contact with the portion 2300c of the conductive portion 2300 .

The first electrical connectors 1800 , the second electrical connectors 1900 and the conductive parts 2300 are all disposed outside the extractor 1100 at intervals. One end of the first electrical connector 1800 is connected with a magnetic member 1801, and another elastic member (not shown in the drawings) is fixed between the magnetic member 1801 and the first electrical connector 1800; one end of the second electrical connector 1900 is connected with The magnetic piece 1901, another elastic piece (not shown in the drawings) is fixed between the magnetic piece 1901 and the second electrical connection piece 1900 .

In this way, when the aerosol generating article 200 is not inserted into the chamber A or is not received in the chamber A, the conductive part 2300 remains disconnected from the first electrical connector 1800 and the second electrical connector 1900, that is, the detection The loop forms a break 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 chamber A through the opening at the upper end of the first housing 10, the bottom end of the aerosol-generating article 200 abuts against the bottom wall 1100a of the extractor 1100 such that The extractor 1100 moves together with the aerosol generating product 200 along the direction of product insertion, thereby driving the conductive part 2300 to move together along the direction of product insertion. When the conductive part 2300 moves a predetermined distance along the product insertion direction, the magnetic part 1801 and the magnetic part 1901 can maintain a magnetic connection with the part 2300d of the conductive part 2300; thus making the first electrical connecting part 1800 and the conductive part 2300 through the magnetic part 1801 To form an electrical connection, the second electrical connector 1900 forms an electrical connection with the conductive part 2300 through the magnetic part 1901; finally, the detection circuit forms a path through the conductive part 2300, the first electrical connector 1800 and the second electrical connector 1900; , the detection circuit can generate a product insertion signal, such as a high-level signal; after the control circuit receives the high-level signal, it can control the heater 14 to automatically start heating. When the aerosol generating article 200 is removed from the chamber A, the above process is reversed; the elastic member (shown as 2301 and 2302 in the figure) can ensure that the conductive part 2300 and the extractor 1100 can return to the original position together.

It can be easily conceived that adjustments can be made based on the structural examples in FIGS. It is also feasible that the conductive part 2300 remains disconnected from the first electrical connector 1800 and the second electrical connector 1900 when the aerosol generating article 200 is inserted into the chamber A.

It should be noted that adjustments can be made based on the structural examples in FIGS. 13-16 , so that the conductive part 2300 moves along with the aerosol generating product 200 along the product insertion direction, while the extractor 1100 does not move along with the aerosol generating product 200 .
