[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] First embodiment

[0029] like Figures 1-8 As shown, the first embodiment of the present application provides a smoking device 10, which includes a heater 11, a chamber 12, a first detection device 13, a second detection device 14, a driving device 15, a cover 16, a power supply device 17, a printed circuit board (PCB) 18 and a controller.

[0030] The heater 11 is used to heat a cigarette removably placed in the chamber 12 to generate an aerosol for smoking. The cigarette contains an aerosol-forming substrate and is used with the smoking article 10 to volatilize at least one component of the aerosol-forming substrate.

[0031] An aerosol-forming substrate is a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. The aerosol-forming substrate can be solid or liquid or comprise both solid and liquid components. The aerosol-forming substrate can be adsorbed, coated, impregnated, or otherwise loaded onto a carrier or support.

[0032] The aerosol-forming substrate may include nicotine. The aerosol-forming substrate may include tobacco, for example, a tobacco-containing material containing volatile tobacco flavor compounds that are released from the aerosol-forming substrate when heated. A preferred aerosol-forming substrate may include a homogenized tobacco material, such as fallen leaf tobacco. The aerosol-forming substrate may include at least one aerosol-forming agent, which may be any suitable known compound or mixture of compounds that, 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, polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as glycerol mono-, di-, or triacetate; and fatty acid esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. Preferred aerosol-forming agents are polyhydric alcohols or mixtures thereof, such as triethylene glycol, 1,3-butanediol, and most preferably, glycerol.

[0033] The heater 11 can be a central heating method (direct contact with the aerosol-forming matrix through the periphery of the heating body) and a peripheral heating method (a cylindrical heating body wraps the aerosol-forming matrix). The heater can also heat the aerosol-forming matrix through one or more methods of heat conduction, electromagnetic induction, chemical reaction, infrared effect, resonance, photoelectric conversion, and photothermal conversion to generate an aerosol that can be inhaled.

[0034] The following description is based on the assumption that the heater 11 is an infrared heater:

[0035] The infrared heater 11 includes a substrate and an infrared electric heating coating (not shown in the drawings).

[0036] The base body can be cylindrical, prismatic, or other cylindrical shapes, preferably cylindrical. A cavity 12 is formed inside the base body, and a through hole corresponding to the cavity 12 is provided on the upper cover 101 of the smoking device 10. A cigarette can be removed from or inserted into the cavity 12 through the through hole.

[0037] The infrared electrothermal coating is formed on the outer surface of the substrate. The infrared electrothermal coating receives electricity from the power supply device 17 through electrodes to generate heat, and transfers the generated heat to the cigarette inserted into the chamber 12 at least in the form of infrared radiation.

[0038] The power supply 17 provides power for operating the smoking device 10. For example, the power supply 17 can provide power to heat the heater 11 and can also provide power required to operate the controller. The power supply 17 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the power supply 17 can be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. The power supply 17 can be a rechargeable battery or a disposable battery.

[0039] The printed circuit board (PCB) 18 may be integrated with, but not limited to, a controller, the second detection circuit in the first detection device 13 , and the first detection circuit in the second detection device 14 .

[0040] The controller can control the overall operation of the smoking article 10. Specifically, the controller controls not only the operation of the power supply 17 and the heater 11, but also the operation of other components in the smoking article 10. In addition, the controller can determine whether the smoking article 10 is operable by checking the status of the components of the smoking article 10.

[0041] The controller includes at least one processor. The processor may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing executable programs in the microprocessor. In addition, those skilled in the art will appreciate that the controller may include another type of hardware.

[0042] Please combine Figure 3-Figure 5 To understand, Figure 3 This is a schematic diagram of the smoking device 10 after removing the upper cover 101. Figure 4 for Figure 3 A partial enlarged schematic diagram, Figure 5 Schematic diagram of the first detection device.

[0043] The first detection device 13 is disposed downstream of the cover 16. The first detection device 13 includes a first elastic sheet 131, a second elastic sheet 132 and a second detection circuit;

[0044] One end of the first elastic piece 131 and one end of the second elastic piece 132 form a through hole for inserting or removing a cigarette, and the controller is electrically connected to the first elastic piece 131 and the second elastic piece 132 via a second detection circuit;

[0045] When a cigarette is not inserted into the through hole, the end of the first elastic piece 131 and the end of the second elastic piece 132 are in contact, i.e., they are embraced together, so that a current path is formed between the second detection circuit, the first elastic piece 131 and the second elastic piece 132;

[0046] 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 and the end of the second elastic piece 132 do not contact each other, and an open circuit with no current passing through is formed between the second detection circuit, the first elastic piece 131 and the second elastic piece 132.

[0047] It should be noted that the upstream and downstream in this embodiment are based on the aerosol flow direction. Figure 2 As shown in the dashed arrow, one end of the arrow is downstream and the other end is upstream.

[0048] Please refer to Figure 2 It is understood that the second detection device 14 includes a contact piece 141, a conductive column 142 and a first detection circuit;

[0049] The contact piece 141 and the conductive post 142 are both disposed at the upstream end of the chamber 12 , and the controller is electrically connected to the contact piece 141 and the conductive post 142 via a first detection circuit;

[0050] When the cigarette is not fully inserted into the chamber 12, the contact piece 141 does not contact the conductive post 142, so that an open circuit is formed between the first detection circuit, the contact piece 141 and the conductive post 142, and no current flows.

[0051] When the cigarette is inserted into the chamber 12 and in place, the contact piece 141 moves downward and contacts the conductive post 142 , so that a current path is formed between the first detection circuit, the contact piece 141 and the conductive post 142 .

[0052] Please combine Figure 6-Figure 8 To understand, Figure 6 This is a schematic diagram of the smoking device 10 after removing the upper cover 101, the front cover and the first detection device 13. Figure 7 for Figure 6 A partial enlarged schematic diagram, Figure 8 Schematic diagram of the driving device 15.

[0053] The driving device 15 is a rotating electromagnet comprising a shaft 151 and a rotating rod 152. The rotating rod 152 is movably connected to the hole 161 of the cover 16. The shaft 151 drives the rotating rod 152 to move transversely of the smoking device 10, thereby driving the cover 16 to move transversely of the smoking device 10 to open or cover the chamber 12.

[0054] In one example, the first detection device 13 is used to detect whether a cigarette is to be inserted into the chamber 12; if it is detected that a cigarette is to be inserted into the chamber 12, the first detection device 13 outputs a cigarette insertion signal;

[0055] The controller is configured to: obtain the cigarette insertion signal; and according to the cigarette insertion signal, control the driving device 15 to drive 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.

[0056] 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 device 10, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 move toward each other, thereby causing the end of the first elastic sheet 131 and the end of the second elastic sheet 132 to not contact each other, and forming an open circuit with no current flowing 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). After the controller obtains the level signal, it can control the drive device 15 to drive the cover 16 to move relative to the chamber 12 to open the chamber 12, thereby allowing the cigarette to pass through the through-hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132 and be inserted into the chamber 12.

[0057] In one example, the second detection device 14 is used to detect whether the cigarette is inserted into the chamber 12; if it is detected that the cigarette is inserted into the chamber 12, it outputs a cigarette insertion signal;

[0058] The controller is further configured to: obtain the cigarette insertion signal; and control the heater 11 to start heating according to the cigarette insertion signal.

[0059] When a cigarette is inserted into chamber 12 through the through-hole formed by one end of first elastic piece 131 and one end of second elastic piece 132, if the cigarette is fully inserted into chamber 12, contact piece 141 moves downward to contact conductive post 142, thereby forming a current path between the first detection circuit, contact piece 141, and conductive post 142. The output end of the first detection circuit outputs a level signal (e.g., a high level signal). After receiving this level signal, the controller controls heater 11 to start heating.

[0060] Specifically, the temperature variation curve of the heater 11 over time generally includes a heating stage, a heat preservation stage, and a suction stage.

[0061] During the heating phase, the temperature of heater 11 is increased from an initial temperature T0 (or ambient temperature) to a preset target temperature T1. The preset target temperature T1 is set to vaporize the desired volatile compounds from the aerosol-forming substrate while preventing the vaporization of undesirable compounds with higher vaporization temperatures. Typically, the preset target temperature T1 may be between 200°C and 400°C.

[0062] During the heat preservation stage, the temperature of the heater 11 is maintained at the preset target temperature T1 for a period of time, so that the aerosol-forming matrix is ​​fully preheated, thereby improving the user's puffing experience.

[0063] The duration of the heating stage is t0-t1, and the duration of the heat preservation stage is t1-t2, where t0-t2 is the preheating time of the heater 11. Generally, the preheating time of the heater 11 is 5 seconds to 30 seconds.

[0064] The inhalation stage is when the user inhales the aerosol generated by the heating of the aerosol generating device 10. In this stage, the temperature of the heater 11 is maintained within a preset temperature range or at a preset temperature for a period of time.

[0065] When the cigarette is inserted into place, the controller controls the heater 11 to start heating, that is, entering the temperature rising stage.

[0066] Furthermore, the first detection device 13 is further configured to output a cigarette removal signal if it is detected that the cigarette is removed from the chamber 12 after the heater 11 completes heating.

[0067] The controller is further configured to: obtain the cigarette removal signal; and control the driving device 15 to drive the cover 16 to move relative to the chamber 12 to cover the chamber 12 according to the cigarette removal signal.

[0068] After controlling the heater 11 to start heating, if the heater 11 completes heating (for example, after the puff is finished), the user pulls the cigarette out of the chamber 12, and the controller automatically controls the drive device 15 to drive the cover 16 to cover the chamber 12 to prevent foreign matter from entering the chamber 12.

[0069] In one example, the second detection device 14 is further configured to output a cigarette insertion failure signal if it is detected that the cigarette is not properly inserted into the chamber 12 after the heater 11 starts heating.

[0070] The controller is further configured to: obtain the cigarette not being inserted properly signal; and control the heater 11 to stop heating and record the heating time completed by the heater 11 according to the cigarette not being inserted properly signal.

[0071] After the heater 11 starts heating, if the cigarette is accidentally moved (it can be any stage among the heating stage, the heat preservation stage, and the smoking stage), the cigarette is not inserted into the chamber 12 properly, that is, the contact piece 141 and the conductive column 142 are not in contact, so that an open circuit with no current is formed between the first detection circuit, the contact piece 141 and the conductive column 142; the output end of the first detection circuit outputs a level signal (for example, a low-level signal), and after the controller obtains the level signal, it controls the heater 11 to stop heating and records the heating time completed by the heater 11.

[0072] Furthermore, the controller is further configured to: generate a first prompt message after the heater 11 stops heating;

[0073] The smoking set 10 further includes:

[0074] The first prompt module is used to obtain the first prompt information to prompt the user that there is an abnormality in the position of the cigarette.

[0075] After the heater 11 starts heating, if the cigarette is accidentally moved, causing the heater 11 to stop heating, the user can be reminded of the abnormality in the position of the cigarette through vibration, light or sound, so that the user can reinsert the cigarette into the chamber 12 in place.

[0076] Furthermore, the second detection device 14 is further configured to output a cigarette reinsertion signal if it is detected that the cigarette is reinserted into the chamber 12 within a first preset time after the heater 11 stops heating.

[0077] The controller is further configured to: obtain the cigarette reinsertion signal; calculate the remaining heating time of the heater 11 based on the heating time completed by the heater 11; and control the heater 11 to heat according to the cigarette reinsertion signal and the remaining heating time of the heater 11.

[0078] After the heater 11 starts heating, if the cigarette is accidentally moved, the heater 11 stops heating. If the user reinserts the cigarette into the chamber 12, the cigarette can continue to be heated without the user having to press the button to start heating again, further simplifying the operation of the smoking device and improving the user experience.

[0079] Furthermore, the first detection device 13 is further configured to output a cigarette removal signal if it is detected that the cigarette is removed from the chamber 12 after the heater 11 completes heating.

[0080] The controller is further configured to: obtain the cigarette removal signal; and control the driving device 15 to drive the cover 16 to move relative to the chamber 12 to cover the chamber 12 according to the cigarette removal signal.

[0081] After controlling the heater 11 to restart heating, if the heater 11 completes heating (for example, after the puff is finished), the user pulls the cigarette out of the chamber 12, and the controller automatically controls the drive device 15 to drive the cover 16 to cover the chamber 12 to prevent foreign matter from entering the chamber 12.

[0082] Furthermore, the first detection device 13 is further configured to output a cigarette removal signal if it is detected that the cigarette is removed from the chamber 12 after the heater 11 stops heating.

[0083] The controller is further configured to: obtain the cigarette removal signal; and control the driving device 15 to drive the cover 16 to move relative to the chamber 12 to cover the chamber 12 according to the cigarette removal signal.

[0084] During the process of the heater 11 starting to heat, if the cigarette is accidentally moved (causing the heater 11 to stop heating) and is pulled out of the chamber 12, the controller automatically controls the driving device 15 to drive the cover 16 to cover the chamber 12.

[0085] Furthermore, the controller is further configured to stop controlling the driving device 15 to drive the cover 16 to move relative to the chamber 12 to open the chamber 12 within a second preset time after the cover 16 has covered the chamber 12 .

[0086] After the cigarette is accidentally pulled out of the chamber 12 and the cover 16 covers the chamber 12, the cover 16 no longer opens the chamber 12 within a second preset time (at this time, the controller can receive the cigarette insertion signal output by the first detection device 13 but does not process it, or the controller does not receive the cigarette insertion signal output by the first detection device 13).

[0087] Furthermore, the controller is further configured to: generate a second prompt message after the cover 16 has covered the chamber 12;

[0088] The smoking device 10 further includes:

[0089] The second prompt module is used to obtain the second prompt information to prompt the user to change the cigarette.

[0090] After the cigarette is accidentally pulled out of the chamber 12 and the cover 16 covers the chamber 12, the user can be prompted to replace the cigarette through vibration, light or sound, preventing the user from reinserting the old cigarette, thereby ensuring the user's taste during use.

[0091] Second embodiment

[0092] like Figure 9 As shown, the second embodiment of the present application provides a method for controlling a smoking device. The specific structure of the smoking device 10 can refer to the content described in the first embodiment and will not be described in detail here.

[0093] The control method of the smoking device includes:

[0094] Step S10: Acquire a cigarette insertion signal output by the first detection device.

[0095] Step S11: According to the cigarette insertion signal, the driving device is controlled to drive the cover to move relative to the chamber to open the chamber, so that the cigarette can be inserted into the chamber.

[0096] Specifically, 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 device 10, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 move toward each other, thereby causing the end of the first elastic sheet 131 and the end of the second elastic sheet 132 to not contact each other, and forming an open circuit with no current flowing 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). After the controller obtains the level signal, it can control the drive device 15 to drive the cover 16 to move relative to the chamber 12 to open the chamber 12, thereby allowing the cigarette to pass through the through-hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132 and be inserted into the chamber 12.

[0097] In one example, the method further includes (not shown in the figures):

[0098] Step S12: obtaining a cigarette insertion signal output by the second detection device;

[0099] Step S13: Control the heater to start heating according to the cigarette insertion signal.

[0100] Specifically, when a cigarette is inserted into chamber 12 through the through-hole formed by one end of first elastic piece 131 and one end of second elastic piece 132, if the cigarette is fully inserted into chamber 12, contact piece 141 moves downward to contact conductive post 142, thereby forming a current path between the first detection circuit, contact piece 141, and conductive post 142. The output end of the first detection circuit outputs a level signal (e.g., a high level signal). After receiving this level signal, the controller controls heater 11 to start heating.

[0101] The temperature variation curve of the heater 11 over time generally includes a heating stage, a heat preservation stage, and a suction stage.

[0102] During the heating phase, the temperature of heater 11 is increased from an initial temperature T0 (or ambient temperature) to a preset target temperature T1. The preset target temperature T1 is set to vaporize the desired volatile compounds from the aerosol-forming substrate while preventing the vaporization of undesirable compounds with higher vaporization temperatures. Typically, the preset target temperature T1 may be between 200°C and 400°C.

[0103] During the heat preservation stage, the temperature of the heater 11 is maintained at the preset target temperature T1 for a period of time, so that the aerosol-forming matrix is ​​fully preheated, thereby improving the user's puffing experience.

[0104] The duration of the heating stage is t0-t1, and the duration of the heat preservation stage is t1-t2, where t0-t2 is the preheating time of the heater 11. Generally, the preheating time of the heater 11 is 5 seconds to 30 seconds.

[0105] The inhalation stage is when the user inhales the aerosol generated by the heating of the aerosol generating device 10. In this stage, the temperature of the heater 11 is maintained within a preset temperature range or at a preset temperature for a period of time.

[0106] When the cigarette is inserted into place, the controller controls the heater 11 to start heating, that is, entering the temperature rising stage.

[0107] In one example, the method further includes (not shown in the figures):

[0108] Step S1411: obtaining a cigarette removal signal output by the first detection device;

[0109] Step S1412: Based on the cigarette removal signal, control the driving device to drive the cover to move relative to the chamber to cover the chamber.

[0110] Specifically, after controlling the heater 11 to start heating, if the heater 11 completes heating (for example, after the puff is finished), the user pulls the cigarette out of the chamber 12, and the controller automatically controls the drive device 15 to drive the cover 16 to cover the chamber 12 to prevent foreign matter from entering the chamber 12.

[0111] In one example, the method further includes (not shown in the figures):

[0112] Step S1421: obtaining a cigarette not properly inserted signal output by the second detection device;

[0113] Step S1422: According to the cigarette not inserted properly signal, the heater is controlled to stop heating and the heating time completed by the heater is recorded.

[0114] Specifically, after the heater 11 starts heating, if the cigarette is accidentally moved (it can be any stage among the heating stage, the heat preservation stage, and the smoking stage), the cigarette is not inserted into the chamber 12 properly, that is, the contact piece 141 and the conductive column 142 are not in contact, so that an open circuit with no current is formed between the first detection circuit, the contact piece 141 and the conductive column 142; the output end of the first detection circuit outputs a level signal (for example, a low-level signal), and after the controller obtains the level signal, it controls the heater 11 to stop heating and records the heating time completed by the heater 11.

[0115] Furthermore, if the heater 11 stops heating, it can also remind the user that there is an abnormality in the position of the cigarette through vibration, light or sound, so that the user can reinsert the cigarette into the chamber 12 in place.

[0116] In one example, the method further includes (not shown in the figures):

[0117] Step S1511: obtaining a cigarette reinsertion signal output by the second detection device;

[0118] Step S1512: Calculate the remaining heating time of the heater based on the completed heating time of the heater;

[0119] Step S1513: Control the heater to perform heating according to the cigarette reinsertion signal and the remaining heating time of the heater.

[0120] Specifically, if the cigarette is accidentally moved, causing the heater 11 to stop heating, the user can continue to heat the cigarette after reinserting it into the chamber 12 without having to press the button again to start heating, further simplifying the operation of the smoking device and improving the user experience.

[0121] Furthermore, after controlling the heater 11 to restart heating, if the heater 11 completes heating (for example, after the puff is finished), the user pulls the cigarette out of the chamber 12 (i.e., obtains the cigarette pulling-out signal output by the first detection device 13), the controller automatically controls the driving device 15 to drive the cover 16 to cover the chamber 12 to prevent foreign matter from entering the chamber 12.

[0122] In one example, the method further includes (not shown in the figures):

[0123] Step S1521: obtaining a cigarette removal signal output by the first detection device;

[0124] Step S1522: According to the cigarette removal signal, control the driving device to drive the cover to move relative to the chamber to cover the chamber.

[0125] Specifically, during the process of the heater 11 starting to heat, if the cigarette is accidentally moved (causing the heater 11 to stop heating) and is pulled out of the chamber 12, the controller automatically controls the driving device 15 to drive the cover 16 to cover the chamber 12.

[0126] In one example, the method further includes (not shown in the figures):

[0127] Step S1523: After the cover has covered the chamber, stop controlling the driving device to drive the cover to move relative to the chamber within a preset time to open the chamber.

[0128] Specifically, after the cigarette is accidentally pulled out of the chamber 12 and the cover 16 covers the chamber 12, the cover 16 no longer opens the chamber 12 within a preset time (at this time, the controller can receive the cigarette insertion signal output by the first detection device 13 but does not process it, or the controller does not receive the cigarette insertion signal output by the first detection device 13).

[0129] Furthermore, after the cigarette is accidentally pulled out of the chamber 12 and the cover 16 covers the chamber 12, the user can be prompted to replace the cigarette through vibration, light or sound, preventing the user from reinserting the old cigarette, thereby ensuring the user's taste during use.

[0130] The following combination Figure 10 The overall control process of the smoking device 10 is described below:

[0131] Step S21, inserting a cigarette;

[0132] Step S22: Detect whether a cigarette is inserted;

[0133] Specifically, when no cigarette is inserted, the end of the first elastic piece 131 and the end of the second elastic piece 132 are in contact, i.e., they are embraced together, so that a current path is formed between the second detection circuit, the first elastic piece 131 and the second elastic piece 132;

[0134] When a cigarette is inserted, 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 and the end of the second elastic piece 132 do not contact each other, and a circuit is formed between the second detection circuit, the first elastic piece 131 and the second elastic piece 132, and no current flows.

[0135] Step S23: If a cigarette is detected to be inserted, the electromagnet drives the cover to open the chamber; otherwise, the detection continues;

[0136] Step S24: After the chamber is opened, the cigarette can be inserted further;

[0137] Step S25: Detecting whether the cigarette is inserted properly;

[0138] Specifically, when the cigarette is not fully inserted into the chamber 12, the contact piece 141 does not contact the conductive post 142, so that an open circuit is formed between the first detection circuit, the contact piece 141 and the conductive post 142, and no current flows.

[0139] When the cigarette is inserted into the chamber 12 and in place, the contact piece 141 moves downward and contacts the conductive post 142 , so that a current path is formed between the first detection circuit, the contact piece 141 and the conductive post 142 .

[0140] Step S26: When the cigarette is inserted into the chamber 12, the controller controls the heater to start heating;

[0141] Step S271, Step S28, Step S29: After the cigarette is heated and removed, the electromagnet drives the cover to close the chamber;

[0142] Step S272, step S273, step S28, step S29: the cigarette is abnormally out of the insertion position, and the controller controls the heater to stop heating; at this time, if the cigarette is pulled out, the electromagnet drives the cover to close the chamber.
