First Embodiment

As shown in FIG. 1-FIG. 8, the first embodiment of the present application provides a smoking set 10. The smoking set 10 includes a heater 11, a cavity 12, a first detection apparatus 13, a second detection apparatus 14, a driving apparatus 15, a cover 16, a power supply apparatus 17, a printed circuit board (PCB) 18 and a controller.
The heater 11 is configured to heat a cigarette removably placed within the cavity 12 to generate an aerosol for smoking. The cigarette includes an aerosol generation substrate for use with the smoking set 10 to volatilize at least one component of the aerosol generation substrate.
The aerosol generation substrate is a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol generation substrate. The aerosol generation substrate may be solid or liquid or include solid and liquid components. The aerosol generation substrate can be loaded onto a carrier or support by means of adsorbing, coating, impregnating, or the like.
The aerosol generation substrate may include nicotine. The aerosol generation substrate may include tobacco, e.g., may include a tobacco-containing material containing volatile tobacco flavor compounds that are released from the aerosol generation substrate when heated. Preferably, the aerosol generation substrate may include a homogenized tobacco material, e.g., deciduous tobacco. The aerosol generation substrate may include at least one aerosol generation agent, which may be any suitable known compound or mixture thereof. When in use, the compounds or mixtures thereof facilitate stable formation of the aerosol, and are substantially resistant to thermal degradation at an operating temperature of an aerosol generation system. Suitable aerosol generation 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 monoacetate, glycerol diacetate and glycerol triacetate; and fatty acid esters of monocarboxylic acid, dicarboxylic acid or polycarboxylic acid, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferably, the aerosol generation agent is polyhydric alcohol or a mixture thereof, such as triethylene glycol, 1,3-butanediol and most preferably glycerol.
The heater 11 may be in a central heating manner (being in contact with the aerosol generation substrate by the periphery of a heating body) or in a peripheral heating manner (the cylindrical heating body wrapping the aerosol generation substrate), and the heater can also heat the aerosol generation substrate by means of one or more of thermal conduction, electromagnetic induction, chemical reaction, infrared action, resonance, photoelectric conversion, and photothermal conversion to generate the aerosol for smoking.
The heater 11, which is an infrared heater, is explained below:
The infrared heater 11 includes a base body and an infrared electrothermal coating (not shown in the drawings).
The base body may be cylindrical, prismatic or another cylindrical shape, preferably cylindrical. A cavity 12 is formed inside the base body, a through hole corresponding to the cavity 12 is formed in an upper cover 101 of the smoking set 10, and the cigarette can be removed or inserted into the cavity 12.
The infrared electrothermal coating is formed on the outer surface of the base body, and the infrared electrothermal coating receives electric power from the power supply apparatus 17 by using electrodes to generate heat, and transfers the generated heat to the cigarette inserted into the cavity 12 at least in the form of infrared radiation.
The power supply apparatus 17 supplies electric power for operating the smoking set 10. For example, the power supply apparatus 17 can supply electric power to heat the heater 11 and can supply electric power needed to operate the controller. The power supply apparatus 17 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the power supply apparatus 17 may be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. The power supply apparatus 17 may be a rechargeable battery or a disposable battery.
The printed circuit board (PCB) 18 may be integrated with but not limited to the controller, a second detection circuit in the first detection apparatus 13, and a first detection circuit in the second detection apparatus 14.
The controller can control the overall operation of the smoking set 10. In detail, the controller not only controls the operation of the power supply apparatus 17 and the heater 11, but also controls the operation of other elements in the smoking set 10. In addition, the controller can determine whether the smoking set 10 can be operated by checking the status of the elements of the smoking set 10.
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 a program executable in the microprocessor. In addition, those skilled in the art should understand that the controller may include another type of hardware.
Please refer to FIG. 3-FIG. 5 for understanding. FIG. 3 is a schematic diagram of the smoking set 10 after the upper cover 101 is removed. FIG. 4 is a partial enlarged schematic diagram of FIG. 3. FIG. 5 is a schematic diagram of the first detection apparatus.
The first detection apparatus 13 is provided downstream of the cover 16. The first detection apparatus 13 includes a first elastic sheet 131, a second elastic sheet 132 and a second detection circuit.
One end of the first elastic sheet 131 and one end of the second elastic sheet 132 form a through hole for insertion or removal of the cigarette, and the controller is electrically connected to the first elastic sheet 131 and the second elastic sheet 132 by using the second detection circuit.
When the cigarette is not inserted into the through hole, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are in contact with each other, that is, embraced together, such that a close circuit through which a current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132.
When the cigarette is inserted into the through hole, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 move to both sides, such that the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are not in contact with each other, and an open circuit through which no current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132.
It should be noted that the upstream and downstream in this embodiment are taken as an example of an aerosol flow direction. As shown in a dashed arrow in FIG. 2, one end of the arrow is downstream and the other end is upstream.
Please refer to FIG. 2 for understanding. The second detection apparatus 14 includes a contact piece 141, a conductive column 142 and a first detection circuit.
Both the contact piece 141 and the conductive column 142 are provided upstream of the cavity 12, and the controller is electrically connected to the conductive column 142 and the contact piece 141 by using the first detection circuit.
When the cigarette inserted into the cavity 12 is not in place, the contact piece 141 is not in contact with the conductive column 142, such that an open circuit through which no current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142.
When the cigarette inserted into the cavity 12 is in place, the contact piece 141 moves downwards to be in contact with the conductive column 142, such that a close circuit through which a current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142.
Please refer to FIG. 6-FIG. 8 for understanding. FIG. 6 is a schematic diagram of the smoking set 10 after the upper cover 101, a front cover and the first detection apparatus 13 are removed. FIG. 7 is a partial enlarged schematic diagram of FIG. 6. FIG. 8 is a schematic diagram of the driving apparatus 15.
The driving apparatus 15 is a rotary electromagnet, including a shaft core 151 and a rotating rod 152. The rotating rod 152 is movably connected to a hole 161 of the cover 16, and the shaft core 151 can drive the rotating rod 152 to move along the lateral direction of the smoking set 10, thereby driving the cover 16 to move along the lateral direction of the smoking set 10 to open or cover the cavity 12.
In an example, the first detection apparatus 13 is configured to detect whether there is a cigarette to be inserted into the cavity 12, and if it is detected that there is a cigarette to be inserted into the cavity 12, output a cigarette insertion signal.
The controller is configured to acquire the cigarette insertion signal, and control, according to the cigarette insertion signal, the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12, so as to open the cavity 12 such that the cigarette can be inserted into the cavity 12.
In this example, when the 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 moves to both sides, such that the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are not in contact with each other, and an open circuit through which no current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132. An output end of the second detection circuit outputs a level signal (e.g., a low level signal). After acquiring the level signal, the controller can control the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12 to open the cavity 12, such that the cigarette can be inserted into the cavity 12 via the through hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132.
In an example, the second detection apparatus 14 is configured to detect whether the cigarette inserted into the cavity 12 is in place, and if it is detected that the cigarette inserted into the cavity 12 is in place, output a cigarette insertion fulfillment signal.
The controller is further configured to acquire the cigarette insertion fulfillment signal, and control, according to the cigarette insertion fulfillment signal, the heater 11 to start heating.
When the cigarette is inserted into the cavity 12 via the through hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132, if the cigarette inserted into the cavity 12 is in place, the contact piece 141 move downwards to be in contact with the conductive column 142, such that a close circuit through which a current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142. An output end of the first detection circuit outputs a level signal (e.g., a high level signal). After acquiring the level signal, the controller controls the heater 11 to start heating.
Specifically, a temperature change curve of the heater 11 over time generally includes a heating phase, a heat preservation phase, and a smoking phase.
In the heating phase, the temperature of the heater 11 is raised from an initial temperature T0 (or an ambient temperature) to a preset target temperature T1. The preset target temperature T1 is set such that desired volatile compounds vaporize from the aerosol generation substrate, and undesired compounds with higher vaporization temperatures do not vaporize. Generally, the preset target temperature T1 may be 200°C-400°C.
In the heat preservation phase, the temperature of the heater 11 is maintained at the preset target temperature T1 for a period of time, such that the aerosol generation substrate is sufficiently preheated and a smoking feeling of a user is improved.
The duration of the heating phase is t0-t1, the duration of the heat preservation phase is t1-t2, and t0-t2 is a preheating time of the heater 11. Generally, the preheating time of the heater 11 is 5s to 30s.
In the smoking phase, the user can smoke the aerosol generated by heating of the aerosol generation system 10. In this phase, the temperature of the heater 11 is maintained within a certain preset temperature range or at a certain preset temperature for a period of time.
When the inserted cigarette is in place, the controller controls the heater 11 to start heating, that is, entering the heating phase.
Furthermore, the first detection apparatus 13 is further configured to output a cigarette pull-out signal, if it is detected that the cigarette is pulled out from the cavity 12 after the heater 11 completes heating.
The controller is further configured to acquire the cigarette pull-out signal, and control, according to the cigarette pull-out signal, the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12, so as to cover the cavity 12.
After controlling the heater 11 to start heating, if the heater 11 completes heating (e.g., after smoking is finished), and the user pulls out the cigarette from the cavity 12, the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12, preventing foreign objects from entering the cavity 12.
In an example, the second detection apparatus 14 is further configured to output a cigarette insertion unfulfillment signal, if it is detected that the cigarette inserted into the cavity 12 is not in place after the heater 11 starts heating.
The controller is further configured to: acquire the cigarette insertion unfulfillment signal, and control, according to the cigarette insertion unfulfillment signal, the heater 11 to stop heating and record a completed heating time of the heater 11.
After the heater 11 starts heating, if the cigarette is accidentally moved (may be in any phase of the heating phase, the heat preservation phase, and the smoking phase), the cigarette will be inserted into the cavity 12 not in place, that is, the contact piece 141 is not in contact with the conductive column 142, such that an open circuit through which no current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142. An output end of the first detection circuit outputs a level signal (e.g., a low level signal), and after acquiring the level signal, the controller controls the heater 11 to stop heating and records the completed heating time of the heater 11.
Furthermore, the controller is further configured to: after the heater 11 stops heating, generate a first prompt message.
The smoking set 10 further includes:
a first prompt module, configured to acquire the first prompt message to prompt the user that the position of the cigarette is abnormal.
After the heater 11 starts heating, if the cigarette is accidentally moved, the heater 11 stops heating, and the user can be prompted that the position of the cigarette is abnormal by means of vibration, light or sound, etc., which is convenient for the user to reinsert the cigarette into the cavity 12 in place.
Furthermore, the second detection apparatus 14 is further configured to output a cigarette reinsertion fulfillment signal, if it is detected that the cigarette is reinserted into the cavity 12 in place within a first preset time after the heater 11 stops heating.
The controller is further configured to: acquire the cigarette reinsertion fulfillment signal, calculate a remaining heating time of the heater 11 according to the completed heating time of the heater 11, and control the heater 11 to heat according to the cigarette reinsertion fulfillment signal and the remaining heating time of the heater 11.
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 cavity 12 in place, the cigarette can be continuously heated, and the user does not need to repress a key to start the heating, which further simplifies the operation of the smoking set and improves the user experience.
Furthermore, the first detection apparatus 13 is further configured to output a cigarette pull-out signal, if it is detected that the cigarette is pulled out from the cavity 12 after the heater 11 completes heating.
The controller is further configured to acquire the cigarette pull-out signal, and control, according to the cigarette pull-out signal, the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12, so as to cover the cavity 12.
After controlling the heater 11 to restart heating, if the heater 11 completes heating (e.g., after smoking is finished), and the user pulls out the cigarette from the cavity 12, the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12, preventing foreign objects from entering the cavity 12.
Furthermore, the first detection apparatus 13 is further configured to output a cigarette pull-out signal, if it is detected that the cigarette is pulled out from the cavity 12 after the heater 11 stops heating.
The controller is further configured to acquire the cigarette pull-out signal, and control, according to the cigarette pull-out signal, the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12, so as to cover the cavity 12.
During the process that the heater 11 starts heating, if the cigarette is accidentally moved (causing the heater 11 to stop heating) and pulled out from the cavity 12, the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12.
Furthermore, the controller is further configured to: after the cover 16 covers the cavity 12, within a second preset time, stop controlling the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12 so as to open the cavity 12.
After the cigarette is accidentally pulled out from the cavity 12 and the cover 16 covers the cavity 12, the cover 16 no longer opens the cavity 12 within the second preset time (in this case, the controller can receive the cigarette insertion signal output by the first detection apparatus 13 but does not process the same, or the controller does not receive the cigarette insertion signal output by the first detection apparatus 13).
Furthermore, the controller is further configured to: after the cover 16 covers the cavity 12, generate a second prompt message.
The smoking set 10 further includes:
a second prompt module, configured to acquire the second prompt message to prompt the user to replace the cigarette.
After the cigarette is accidentally pulled out from the cavity 12 and the cover 16 covers the cavity 12, the user can be prompted to replace the cigarette by means of vibration, light or sound, etc., preventing the user from reinserting the old cigarette, and ensuring the mouth feeling of the user during use.

Second Embodiment

As shown in FIG. 9, the second embodiment of the present application provides a control method for a smoking set. For the specific structure of the smoking set 10, reference can be made to the content of the first embodiment, which will not be repeated here.
The control method for a smoking set includes:

Step S10: Acquire a cigarette insertion signal output by a first detection apparatus.
Step S11: Control, according to the cigarette insertion signal, a driving apparatus to drive a cover to move relative to a cavity, so as to open the cavity such that the cigarette can be inserted into the cavity.

Specifically, when the 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 moves to both sides, such that the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are not in contact with each other, and an open circuit through which no current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132. An output end of the second detection circuit outputs a level signal (e.g., a low level signal). After acquiring the level signal, the controller can control the driving apparatus 15 to drive the cover 16 to move relative to the cavity 12 to open the cavity 12, such that the cigarette can be inserted into the cavity 12 via the through hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132.
In an example, the method further includes (not shown in drawings):

Step S12: Acquire a cigarette insertion fulfillment signal output by a second detection apparatus.
Step S13: Control a heater to start heating according to the cigarette insertion fulfillment signal.

Specifically, when the cigarette is inserted into the cavity 12 via the through hole formed by one end of the first elastic sheet 131 and one end of the second elastic sheet 132, if the cigarette inserted into the cavity 12 is in place, the contact piece 141 move downwards to be in contact with the conductive column 142, such that a close circuit through which a current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142. An output end of the first detection circuit outputs a level signal (e.g., a high level signal). After acquiring the level signal, the controller controls the heater 11 to start heating.
A temperature change curve of the heater 11 over time generally includes a heating phase, a heat preservation phase, and a smoking phase.
In the heating phase, the temperature of the heater 11 is raised from an initial temperature T0 (or an ambient temperature) to a preset target temperature T1. The preset target temperature T1 is set such that desired volatile compounds vaporize from the aerosol generation substrate, and undesired compounds with higher vaporization temperatures do not vaporize. Generally, the preset target temperature T1 may be 200°C-400°C.
In the heat preservation phase, the temperature of the heater 11 is maintained at the preset target temperature T1 for a period of time, such that the aerosol generation substrate is sufficiently preheated and a smoking feeling of a user is improved.
The duration of the heating phase is t0-t1, the duration of the heat preservation phase is t1-t2, and t0-t2 is a preheating time of the heater 11. Generally, the preheating time of the heater 11 is 5s to 30s.
In the smoking phase, the user can smoke the aerosol generated by heating of the aerosol generation system 10. In this phase, the temperature of the heater 11 is maintained within a certain preset temperature range or at a certain preset temperature for a period of time.
When the inserted cigarette is in place, the controller controls the heater 11 to start heating, that is, entering the heating phase.
In an example, the method further includes (not shown in drawings):

Step S1411: Acquire a cigarette pull-out signal output by the first detection apparatus.
Step S1412: Control, according to the cigarette pull-out signal, the driving apparatus to drive the cover to move relative to the cavity, so as to cover the cavity.

Specifically, after controlling the heater 11 to start heating, if the heater 11 completes heating (e.g., after smoking is finished), the user pulls out the cigarette from the cavity 12, the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12, preventing foreign objects from entering the cavity 12.
In an example, the method further includes (not shown in drawings):

Step S1421: Acquire a cigarette insertion unfulfillment signal output by the second detection apparatus.
Step S1422: Control, according to the cigarette insertion unfulfillment signal, the heater to stop heating and record a completed heating time of the heater.

Specifically, after the heater 11 starts heating, if the cigarette is accidentally moved (can be in any phase of the heating phase, the heat preservation phase, and the smoking phase), the cigarette inserted into the cavity 12 will be not in place, that is, the contact piece 141 is not in contact with the conductive column 142, such that an open circuit through which no current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142. An output end of the first detection circuit outputs a level signal (e.g., a low level signal), and after acquiring the level signal, the controller controls the heater 11 to stop heating and records the completed heating time of the heater 11.
Furthermore, if the heater 11 stops heating, the user can be prompted that the position of the cigarette is abnormal by means of vibration, light or sound, etc., which is convenient for the user to reinsert the cigarette into the cavity 12 in place.
In an example, the method further includes (not shown in drawings):

Step S1511: Acquire a cigarette reinsertion fulfillment signal output by the second detection apparatus.
Step S1512: Calculate a remaining heating time of the heater according to the completed heating time of the heater.
Step S1513: Control the heater to heat according to the cigarette reinsertion fulfillment signal and the remaining heating time of the heater.

Specifically, because the cigarette is accidentally moved, the heater 11 stops heating. If the user reinserts the cigarette into the cavity 12 in place, the cigarette can be continuously heated, and the user does not need to repress a key to start the heating, which further simplifies the operation of the smoking set and improves the user experience.
Furthermore, after controlling the heater 11 to restart heating, if the heater 11 completes heating (e.g., after smoking is finished), and the user pulls out the cigarette from the cavity 12 (that is, acquiring the cigarette pull-out signal output by the first detection apparatus 13), the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12, preventing foreign objects from entering the cavity 12.
In an example, the method further includes (not shown in drawings):

Step S1521: Acquire the cigarette pull-out signal output by the first detection apparatus.
Step S1522: Control, according to the cigarette pull-out signal, the driving apparatus to drive the cover to move relative to the cavity, so as to cover the cavity.

Specifically, during the process that the heater 11 starts heating, if the cigarette is accidentally moved (causing the heater 11 to stop heating) and pulled out from the cavity 12, the controller automatically controls the driving apparatus 15 to drive the cover 16 to cover the cavity 12.
In an example, the method further includes (not shown in drawings):
Step S1523: After the cover covers the cavity, within a preset time, stop controlling the driving apparatus to drive the cover to move relative to the cavity, so as to open the cavity.
Specifically, after the cigarette is accidentally pulled out from the cavity 12 and the cover 16 covers the cavity 12, the cover 16 no longer opens the cavity 12 within the preset time (in this case, the controller can receive the cigarette insertion signal output by the first detection apparatus 13 but does not process the same, or the controller does not receive the cigarette insertion signal output by the first detection apparatus 13).
Furthermore, after the cigarette is accidentally pulled out from the cavity 12 and the cover 16 covers the cavity 12, the user can be prompted to replace the cigarette by means of vibration, light or sound, etc., preventing the user from reinserting the old cigarette, and ensuring the mouth feeling of the user during use.
An overall control process of the smoking set 10 will be described below with reference to FIG. 10:

Step S21: Insert a cigarette.
Step S22: Detect whether the cigarette is inserted.

Specifically, when the cigarette is not inserted, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are in contact with each other, that is, embraced together, such that a close circuit through which a current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132.
When the cigarette is inserted, the end of the first elastic sheet 131 and the end of the second elastic sheet 132 move to both sides, such that the end of the first elastic sheet 131 and the end of the second elastic sheet 132 are not in contact with each other, and an open circuit through which no current passes is formed between the second detection circuit, the first elastic sheet 131 and the second elastic sheet 132.
Step S23: If it is detected that the cigarette is inserted, an electromagnet drives the cover to open the cavity, and otherwise, the detection is continued.
Step S24: After the cavity is opened, the cigarette can be continuously inserted.
Step S25: Detect whether the inserted cigarette is in place.
Specifically, when the cigarette inserted into the cavity 12 is not in place, the contact piece 141 is not in contact with the conductive column 142, such that an open circuit through which no current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142.
When the cigarette inserted into the cavity 12 is in place, the contact piece 141 moves downwards to be in contact with the conductive column 142, such that a close circuit through which a current passes is formed between the first detection circuit, the contact piece 141 and the conductive column 142.
Step S26: When the cigarette inserted into the cavity 12 is in place, the controller controls the heater to start heating.
Step S271, Step S28, Step S29: If heating of the cigarette is completed and the cigarette is pulled out, the electromagnet drives the cover to close the cavity.
Step S272, step S273, step S28, step S29: If the cigarette is abnormally removed from an insertion position, the controller controls the heater to stop heating; in this case, if the cigarette is pulled out, the electromagnet drives the cover to close the cavity.
