The heater 11 is used to heat a cigarette removably placed in the chamber 12 to generate an aerosol for smoking. A tobacco rod comprises an aerosol-forming substrate for use with smoking article 10 to volatilise at least one component of the aerosol-forming substrate.

An aerosol-forming substrate is a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may be solid or liquid or comprise solid and liquid components. The aerosol-forming substrate may be adsorbed, coated, impregnated or otherwise loaded onto a carrier or support.

The aerosol-forming substrate may comprise nicotine. The aerosol-forming substrate may comprise tobacco, for example may comprise a tobacco-containing material containing volatile tobacco flavour compounds which are released from the aerosol-forming substrate when heated. Preferred aerosol-forming substrates may comprise homogenised tobacco material, for example deciduous tobacco. The aerosol-forming substrate may comprise at least one aerosol-former, which may be any suitable known compound or mixture of compounds which, in use, facilitates stable aerosol formation and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating system. Suitable aerosol-forming agents are well known in the art and include, but are not limited to: polyhydric alcohols such as triethylene glycol, 1, 3-butanediol and glycerin; esters of polyhydric alcohols, such as glycerol mono-, di-or triacetate; and fatty acid esters of mono-, di-or polycarboxylic acids, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferred aerosol formers are polyhydric alcohols or mixtures thereof, such as triethylene glycol, 1, 3-butanediol, and most preferably glycerol.

The heater 11 may be a central heating mode (in which the heater is in direct contact with the aerosol-forming substrate through the periphery of the heater) or a peripheral heating mode (in which the cylindrical heater wraps the aerosol-forming substrate), or may be a heater that heats the aerosol-forming substrate through one or more of heat conduction, electromagnetic induction, chemical reaction, infrared action, resonance, photoelectric conversion, and photothermal conversion to generate aerosol for inhalation.

The following description will be made with the heater 11 as an infrared heater:

the infrared heater 11 includes a substrate and an infrared electrothermal coating (not shown in the drawings).

The matrix may be cylindrical, prismatic or other cylindrical, preferably cylindrical. The base body forms a chamber 12 inside, and the upper cover 101 of the smoking set 10 is provided with a through hole corresponding to the chamber 12, through which the cigarette rod can be removed or inserted into the chamber 12.

An infrared electrothermal coating is formed on the outer surface of the base body, and receives the electric power from the power supply unit 17 through the electrodes to generate heat and transfers the generated heat to the cigarette inserted in the chamber 12 at least in the form of infrared radiation.

And a power supply device 17 for supplying power for operating the smoking set 10. For example, the power supply device 17 may supply power to heat the heater 11, and may supply power required to operate the controller. The power supply device 17 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the power supply device 17 may be a lithium cobaltate (LiCoO2) battery or a lithium titanate battery. The power supply means 17 may be a rechargeable battery or a disposable battery.

Printed Circuit Board (PCB) 18 may be integrated with, but not limited to, a controller, a second detection Circuit in first detection device 13, and a first detection Circuit in second detection device 14.

In detail, the controller controls not only the operation of the power supply means 17 and the heater 11, but also the operation of other elements in the smoking article 10. Further, the controller may determine whether the smoking article 10 is operable by examining the status of the elements of the smoking article 10.

The controller includes at least one processor. The processor may comprise an array of logic gates, or may comprise a combination of a general purpose microprocessor and memory storing programs executable in the microprocessor.

Please refer to fig. 3 to 5, fig. 3 is a schematic view of the smoking set 10 with the upper cover 101 removed, fig. 4 is a partially enlarged schematic view of fig. 3, and fig. 5 is a schematic view of the first detecting device.

The first detection means 13 are arranged downstream of the cover 16. The first detecting device 13 includes a first elastic sheet 131, a second elastic sheet 132 and a second detecting circuit;

one end of the first elastic sheet 131 and one end of the second elastic sheet 132 form a through hole for inserting or removing the cigarette, and the controller is electrically connected with the first elastic sheet 131 and the second elastic sheet 132 through the second detection circuit;

when the cigarette is not inserted into the through hole, the end of the first elastic sheet 131 contacts with the end of the second elastic sheet 132, that is, the two elastic sheets are encircled together, so that a current passing path is formed among the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132;

when a cigarette is inserted into the through hole, the end of the first elastic piece 131 and the end of the second elastic piece 132 move to both sides, so that the end of the first elastic piece 131 is not in contact with the end of the second elastic piece 132, and an open circuit through which no current passes is formed among the second detection circuit, the first elastic piece 131 and the second elastic piece 132.

In the present embodiment, the upstream and downstream are both in the aerosol flow direction as an example. As shown by the dashed arrows in fig. 2, one end of the arrow is downstream and the other end is upstream.

As can be understood with reference to fig. 2, the second detecting device 14 includes a contact pad 141, a conductive pillar 142, and a first detecting circuit;

when the cigarette is not inserted into the chamber 12 in place, the contact piece 141 is not in contact with the conductive post 142, so that an open circuit without current passing through is formed among the first detection circuit, the contact piece 141 and the conductive post 142;

when the cigarette is inserted into the chamber 12, the contact plate 141 moves downward to contact the conductive post 142, so that a current path is formed among the first detection circuit, the contact plate 141 and the conductive post 142.

Please refer to fig. 6-8, in which fig. 6 is a schematic view of the smoking set 10 with the upper cover 101, the front cover and the first detecting device 13 removed, fig. 7 is a partially enlarged schematic view of fig. 6, and fig. 8 is a schematic view of the driving device 15.

The driving device 15 is a rotary electromagnet, and includes a shaft core 151 and a rotary rod 152. The rotating rod 152 is movably connected to the hole 161 of the cover 16, and the shaft core 151 can drive the rotating rod 152 to move along the transverse direction of the smoking article 10, so as to drive the cover 16 to move along the transverse direction of the smoking article 10 to open or cover the chamber 12.

a controller configured to: acquiring the cigarette insertion signal; in response to the cigarette insertion signal, the control drive means 15 drives the cover 16 to move relative to the chamber 12 to open the chamber 12 so that the cigarette can be inserted into the chamber 12.

In this example, when a cigarette is inserted into the through hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132 through the upper cover 101 of the smoking set 10, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 move to both sides, so that the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are not in contact, and a break through which no current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132. The output end of the second detection circuit outputs a level signal (e.g. a low level signal), and after the controller obtains the level signal, the controller may control the driving device 15 to drive the cover 16 to move relative to the chamber 12 so as to open the chamber 12, so that the cigarette may be inserted into the chamber 12 through the through hole formed by the one end of the first elastic sheet 131 and the one end of the second elastic sheet 132.

In the temperature increasing stage, the temperature of the heater 11 is increased from the initial temperature T0 (or the ambient temperature) to the preset target temperature T1. The preset target temperature T1 is set such that desired volatile compounds are vaporised from the aerosol-forming substrate, whereas undesired compounds having a higher vaporisation temperature are not vaporised. Generally, the preset target temperature T1 may be 200-400 ℃.

During the hold phase, the temperature of the heater 11 is maintained at the preset target temperature T1 for a period of time to allow sufficient preheating of the aerosol-forming substrate to enhance the mouth feel of the puff by the user.

In an example, the second detection device 14 is further configured to output a cigarette not-inserted-position signal if it is detected that the cigarette insertion chamber 12 is not in position after the heater 11 starts heating;

the controller further configured to: acquiring a cigarette insertion missing position signal; according to the cigarette inserting position failing signal, the heater 11 is controlled to stop heating, and the heating time of the heater 11 is recorded.

After the heater 11 is started to heat, if the cigarette is accidentally stirred (which may be any one of a temperature rise stage, a heat preservation stage and a suction stage), the cigarette is not inserted into the chamber 12 in place, that is, the contact piece 141 is not in contact with the conductive post 142, so that a circuit break without current passing through is formed among the first detection circuit, the contact piece 141 and the conductive post 142; the output end of the first detection circuit outputs a level signal (for example, a low level signal), and after the controller acquires the level signal, the controller controls the heater 11 to stop heating and records the heating time of the heater 11.

Further, the controller is further configured to: after the heater 11 stops heating, generating first prompt information;

After the heater 11 starts heating, if the cigarette is accidentally stirred, the heater 11 stops heating. If the user inserts cigarette again and puts in place the back in chamber 12, can continue to heat cigarette, need not the user and press a button again and start the heating, further simplified the operation of smoking set, promoted user experience.

After controlling the heater 11 to restart heating, if the heater 11 finishes heating (for example, after the smoking is finished), the user pulls out the cigarette from the chamber 12, and the controller automatically controls the driving device 15 to drive the cover 16 to cover the chamber 12, so as to prevent the foreign matters from entering the chamber 12.

Further, the first detecting device 13 is further configured to output a cigarette pulling signal if it is detected that the cigarette is pulled out from the chamber 12 after the heater 11 stops heating;

The output end of the second detection circuit outputs a level signal (e.g. a low level signal), and after the controller obtains the level signal, the controller may control the driving device 15 to drive the cover 16 to move relative to the chamber 12 so as to open the chamber 12, so that the cigarette may be inserted into the chamber 12 through the through hole formed by the one end of the first elastic sheet 131 and the one end of the second elastic sheet 132.

In one example, the method further comprises (not shown in the figures):

step S12, acquiring a cigarette insertion in-place signal output by the second detection device;
