Detailed Description

To facilitate an understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and detailed description. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "upper", "lower", "left", "right", "inner", "outer" and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. 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.

Fig. 1 is an aerosol-generating device provided in an embodiment of the present application, including:

a chamber within which an aerosol-generating article 40 is removably received;

a heater 10, the heater 10 being inserted into the aerosol-generating article 40 for heating to generate an aerosol when the aerosol-generating article 40 is received within the chamber;

the battery cell 20 is used for supplying power;

a circuit 30 arranged between the cell 20 and the heater 10 to control the aerosol-generating device; for example, the control cell 20 supplies power to the heater 10.

The aerosol-generating article 40 preferably employs a tobacco-containing material that releases volatile compounds from a substrate upon heating; or it may be a non-tobacco material that is suitable for electrically heated smoking after heating. The aerosol-generating article 40 preferably employs a solid substrate, and may comprise one or more of a powder, granules, shredded strips, strips or flakes of one or more of vanilla leaf, tobacco leaf, homogenized tobacco, expanded tobacco; alternatively, the solid substrate may contain additional tobacco or non-tobacco volatile flavour compounds to be released when the substrate is heated.

The heating method of the heater 10 includes, but is not limited to, resistance heating, electromagnetic heating, and infrared heating. The shape of the heater 10 includes, but is not limited to, a needle shape, a pin shape, or a sheet shape.

Fig. 7 shows a schematic view of the heater 10 in one embodiment, the heater 10 comprising a body portion 10a and a flange 10 b. The body portion 10a has a first end, a second end opposite the first end; a first end of the body portion 10a may be inserted into the aerosol-generating article 40 and the flange 10b is disposed adjacent a second end of the body portion 10 a.

In the example according to fig. 1, the aerosol-generating device further comprises a sensor, which is not limited to a pressure sensor, a micro switch, etc. The sensor is for receiving a force transmitted by the heater 10 when the first end of the body portion 10a is inserted into the aerosol-generating article 40 to generate an aerosol-generating article insertion signal; thereby causing the circuit 30 to control the action of the heater 10 based on the aerosol-generating article insertion signal generated by the sensor. It will be appreciated that when the first end of the body portion 10a is inserted into the aerosol-generating article 40, contact between the body portion 10a and the aerosol-generating article 40 will create a force; for example: friction between the outer surface of the body portion 10a and the aerosol-generating article 40.

Upon determining that the aerosol-generating article 40 has been inserted, the circuit 30 may control the heater 10 to activate heating; no user action is required to control the heater 10 to initiate heating. Upon determining that the aerosol-generating article 40 has been pulled out or that the aerosol-generating article 40 is not inserted, the circuit 30 may control the heater 10 to stop heating, avoiding unnecessary power loss.

Figures 2-6 show schematic diagrams of a heating component in an aerosol-generating device in one embodiment. The heating assembly comprises a holder 11, the holder 11 being substantially cup-shaped in configuration, having a closed end 11a and an open end 11 b; the hollow a of which forms at least part of said chamber. The closed end 11a of the holder 11 has a through hole 11c therein, and the flange 10b is at least partially retained within the through hole 11 c. Further, the inner wall of the via hole 11c has a protruding stopper 11d thereon, and the flange 10b is provided on the stopper 11 d. The number and shape of the stoppers 11d are not limited herein.

The heating assembly further comprises a first abutment 12, the first abutment 12 being tubular and being sleeved on the holder 11. Specifically, the open end 11b of the holder 11 has an extension 11e extending radially, the extension 11e being held on the end face of the first abutment 12; this brings the holder 11 into abutment with the first abutment 12. The first abutment 12 further has a groove 12a, the groove 12a being formed by at least a partial end surface depression of the first abutment 12.

In the example of fig. 2-6, the sensor 13 is partially housed within the groove 12a, i.e. the sensor 13 is arranged between the holder 11 and the first abutment 12. When the first end of the body portion 10a is inserted into the aerosol-generating article 40, the holder 11 receives a force transmitted by the heater 10 to transmit at least a portion of the force to the sensor 13, thereby generating an aerosol-generating article insertion signal.

Further in an alternative embodiment, the heating assembly may also comprise a second abutment 15 in abutment with the first abutment 12, the sensor 14 being arranged between the first abutment 12 and the second abutment 15. When the first end of the body portion 10a is inserted into the aerosol-generating article 40, the force transmitted by the heater 10 is received by the holder 11 and transmitted to the sensor 14 via the first abutment 12, so that the pressure sensor generates an aerosol-generating article insertion signal. It is conceivable that only the sensor 13 or the sensor 14 may be provided, or that both the sensor 13 and the sensor 14 may be provided.

In the example of fig. 2-6, the first abutment member 12 or the second abutment member 15 may be a separate structural member or may be part of another structural member.

In another example, unlike fig. 2-6, it is also possible that a sensor may be provided between the heater 10 and the holder 11. In this way, the force delivered by the heater 10 may be applied directly to the sensor, thereby generating an aerosol-generating article insertion signal.

It should be noted that the description of the present application and the accompanying drawings set forth preferred embodiments of the present application, however, 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, but are provided for the purpose of providing a more thorough understanding of the present disclosure. 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.
