[0051] Embodiment 1

[0052] Heated cigarettes are a type of new tobacco product that uses electric heating to bake cigarettes at low temperatures, allowing the cigarettes to produce smoke without burning. Existing heated tobacco devices usually use heat conduction to heat cigarettes, that is, the heating element is in direct contact with the smoke-generating substrate, and the heat of the heating element is conducted to heat the smoke-generating substrate in the cigarette to form an aerosol. There are two problems. On the one hand, the heating element is small in size and has a small contact area with the smoke-generating substrate, resulting in a limited amount of smoke-generating substrate material available for baking. In addition, it is difficult to fully bake the smoke-generating substrate that is not in direct contact with the heating element, and the amount of smoke will gradually decrease when the user smokes in the later stage; on the other hand, after the smoking is completed, the high-temperature smoke-generating substrate may adhere to the heating element and need to be manually cleaned and removed.

[0053] In this regard, this embodiment provides a heated cigarette smoking device to solve the problem in the prior art that heating cigarettes by heat conduction will result in a limited amount of smoking matrix material available for baking and the high-temperature smoking matrix may adhere to the heating element. It can be used in the technical field of heated cigarette smoking devices.

[0054] Reference Figure 1-Figure 2 The heated cigarette smoking device includes a smoking device shell, which has a receiving cavity for placing cigarettes, and the cigarettes contain a smoking substrate for generating smoke or aerosol. The heated cigarette smoking device also includes a base 1, a heating module 2, and a vibration module 3. The base 1 is connected to the smoking device shell; the heating module 2 extends into the receiving cavity and includes a shell 21 and a heating core 22. The heated cigarette smoking device has a heating cavity 23, which is formed by the shell 21 and the cavity in the base 1. The heating core 22 is arranged inside the heating cavity 23, connected to the base 1, and used to generate heat. The shell 21 is provided with a through-hole component 211 for gas and heat to pass through, so that the heat emitted by the heating core 22 can enter the receiving cavity through the heating cavity 23 and the through-hole component 211 in turn to heat the cigarette. That is to say, the heating module 2 uses air as a heat transfer medium to transfer heat to the smoking substrate of the cigarette, which can increase the utilization rate of heat, increase the baking area of ​​the smoking substrate, and increase the amount of aerosol generated. The vibration module 3 can vibrate relative to the base 1 and is connected to the shell 21, so that the vibration of the vibration module 3 can drive the shell 21 to vibrate, and then drive the cigarette to vibrate, so that the gap of the smoking matrix changes, and the airflow direction inside the smoking matrix can be changed, so that the hot air can flow evenly to the smoking matrix at different positions along the gap of the smoking matrix, making the baking more complete and uniform. In addition, the vibration makes it difficult for the smoking matrix to adhere to the shell 21, preventing the through-hole component 211 from being blocked, which is convenient for cleaning.

[0055] In this embodiment, the heating core 22 is columnar and is disposed inside the housing 21 to maximize the use of the heat generated by the heating core 22. A heating circuit is disposed on the heating core 22 to generate heat. Specifically, the heating circuit is electrically connected to a power source and can generate heat when powered. Optionally, the heating circuit is arranged in a spiral along the side wall of the heating core 22 to increase the length of the heating core 22 as much as possible.

[0056] In another embodiment, the heating core 22 is tubular and has a plurality of air holes. In order to prevent the heating core 22 from affecting the vibration of the housing 21, the outer wall of the heating core 22 is gap-matched with the inner wall of the housing 21. By setting the heating core 22 to be tubular, the contact area between the heating core 22 and the gas can be increased, thereby improving the heat exchange efficiency between the heating core 22 and the gas.

[0057] In some other embodiments, the heating core 22 may be in other shapes, such as shaft-shaped, sheet-shaped, etc. In addition, the heating core 22 may also be disposed in a cavity within the base 1 to prevent the shell 21 from colliding with the heating core 22 during vibration.

[0058] Optionally, the through hole assembly 211 includes a plurality of through hole groups 212 spaced apart along the axial direction of the shell 21, and each of the plurality of through hole groups 212 includes a plurality of through holes 213 spaced apart along the circumferential direction of the shell 21, so that the through holes 213 are dispersed and evenly arranged on the entire surface of the shell 21, so that hot air can flow evenly to the smoke-generating substrate at different positions.

[0059] Continue to refer to Figure 1-Figure 2 The base 1 has an installation cavity 11. Optionally, the cavity between the inner wall of the shell 21 and the heating core 22 is connected to the installation cavity 11. The vibration module 3 includes a vibration motor 31 and a vibration flange 32 connected to the vibration motor 31. The vibration flange 32 is arranged in the installation cavity 11. The shell 21 is connected to the vibration flange 32. The vibration motor 31 is used to generate vibration and drive the vibration flange 32 to vibrate, thereby driving the shell 21 to vibrate. Optionally, the vibration motor 31 is embedded in the vibration flange 32, and the vibration motor 31 is used to drive the vibration flange 32 to vibrate in a direction perpendicular to the axis of the heating core 22.

[0060] Continue to refer to Figure 1-Figure 2 A reset elastic member 4 is provided between the outer periphery of the vibration flange 32 and the inner wall of the mounting cavity 11. The reset elastic member 4 is used to provide an elastic force for moving the vibration flange 32 so that the axis of the vibration flange 32 coincides with the center line of the mounting cavity 11, so that the vibration flange 32 is located at the center position of the mounting cavity 11 when the vibration motor 31 is not turned on. After the vibration motor 31 is turned on, the vibration flange 32 will also be subjected to the elastic force moving toward the center position of the mounting cavity 11 to avoid excessive amplitude, and the vibration flange 32 can be reset after the vibration motor 31 stops.

[0061] Continue to refer to Figure 1-Figure 2 The bottom wall of the vibration flange 32 is rotatably connected to a roller 321 , and the roller 321 is in rolling contact with the bottom wall of the installation cavity 11 , thereby reducing the friction resistance when the vibration flange 32 moves relative to the bottom wall of the installation cavity 11 .

[0062] Continue to refer to Figure 1-Figure 2 The base 1 has an airflow cavity 12, and the cavity between the inner wall of the shell 21 and the heating core 22 is connected to the airflow cavity 12, that is, the heating element 22 is located between the airflow cavity 12 and the through-hole component 211. The heated cigarette smoking device also includes an airflow generator 5. In this embodiment, the airflow generator 5 is arranged in the airflow cavity 12 to save space. In other embodiments, the airflow generator 5 can be arranged outside the airflow cavity 11. The airflow generator 5 is used to blow gas into the accommodating cavity. The gas flows through the heating element 22 and finally flows out from the through-hole component 211 and enters the accommodating cavity, thereby heating the smoking substrate. Such an arrangement can promote hot air to flow to the accommodating cavity and enhance the heating effect. In addition, since the gas flows out through the through-hole component 211, the smoking substrate can be prevented from blocking the through-hole component 211.

[0063] Continue to refer to Figure 1-Figure 2 The thermal conductivity of the shell 21 is lower than that of the heating core 22, that is, the thermal conductivity of the shell 21 is low, while the thermal conductivity of the heating core 22 is high, so that the heat can be quickly transferred from the heating core 22 to the surroundings, and most of the heat is transferred to the cigarette through the through-hole 211 component, rather than transferring the heat to the cigarette by heating the shell 21, so as to avoid the temperature of the part where the shell 21 is in direct contact with the cigarette being too high.

[0064] Continue to refer to Figure 1-Figure 2 The airflow cavity 12 includes a first cavity 121 for accommodating the airflow generator 5 and a second cavity 122 connected to the first cavity 121. The cavity between the inner wall of the housing 21 and the heating core 22 is connected to the second cavity 122. Along the flow direction of the gas, the cross-sectional area of ​​the second cavity 122 gradually decreases, thereby guiding the gas emitted by the airflow generator 5 and reducing the flow resistance of the gas. Optionally, the cavity wall of the second cavity 122 is in an inverted funnel shape as a whole.

[0065] Embodiment 2

[0066] This embodiment provides a method for controlling a heated cigarette smoking article, which is implemented by the heated cigarette smoking article described above.

[0067] Reference Figure 3 The method for controlling the heated cigarette smoking device includes the following steps.

[0068] S100: Determine that a preset time has been reached.

[0069] S110: Turn on the vibration module 3, and turn off the vibration module 3 after a set time.

[0070] After reaching the preset time, the vibration module 3 is turned on to make the housing 21 and the cigarette vibrate. The preset time can be set according to different needs, thereby forming different solutions and having different effects, as follows:

[0071] One of the solutions is that the vibration module 3 is mainly used to vibrate the shell 21 and the smoke-generating substrate to improve the flow of air. At this time, the preset time is in the middle or late stage of smoking. At this time, the smoke-generating substrate close to the shell 21 has been baked, and the flow path of air between the smoke-generating substrates is relatively fixed. At this time, it is necessary to turn on the vibration module 3 to vibrate the smoke-generating substrate, change the relative position between the smoke-generating substrates and the flow path of air between the smoke-generating substrates, so as to make the air flow between the smoke-generating substrates more uniform and avoid a decrease in the amount of smoke in the middle or late stage of smoking.

[0072] Another solution is that the vibration module 3 is mainly used to serve as a reminder. In this solution, the preset time can be set when the smoking device is just started, when the preheating is completed and the smoking device can be smoked, when the remaining heating time is about to stop (for example, when the remaining heating countdown is 30s), and when the heating is stopped, so as to remind the user of the current state of the heating device.

[0073] In step S110, the target vibration parameter corresponding to the current preset moment is obtained based on the first mapping relationship between different preset moments and the target vibration parameter, and the vibration module 3 is controlled to vibrate based on the target vibration parameter, and the target vibration parameter is one or more of the target amplitude, target vibration frequency and target vibration duration. The first mapping relationship can be obtained through a large number of simulations or experiments in the early stage and stored in the controller.

[0074] In the scheme where the target vibration parameter includes the target amplitude, and at the current preset moment, when the main purpose of the vibration is to vibrate the housing 21 and the smoking substrate, the target amplitude is the first amplitude. At the current preset moment, when the main purpose of the vibration is to remind the user, the target amplitude is the second amplitude, which is greater than the first amplitude to play a stronger reminder role.

[0075] In the scheme where the target vibration parameter includes the target vibration frequency, and at the current preset moment, when the main purpose of the vibration is to vibrate the housing 21 and the smoking substrate, the target vibration frequency is the first vibration frequency. At the current preset moment, when the main purpose of the vibration is to remind the user, the target vibration frequency is the second vibration frequency, which is greater than the first vibration frequency to play a stronger reminder role.

[0076] In the scheme where the target vibration parameter includes the target vibration duration, and at the current preset moment, when the main purpose of the vibration is to vibrate the housing 21 and the smoking substrate, the target vibration duration is the first vibration duration. At the current preset moment, when the main purpose of the vibration is to remind the user, the target vibration duration is the second vibration duration, and the second vibration duration is greater than the first vibration duration to play a stronger reminder role.

[0077] Optionally, the setting time for turning on the vibration module 3 can also be determined according to different preset moments, specifically, the setting time corresponding to the current preset moment is obtained based on the second mapping relationship between different preset moments and setting times. The second mapping relationship can be obtained through a large number of simulations or experiments in the early stage and stored in the controller.

[0078] S120: Increase the power of the airflow generator 5.

[0079] Regardless of the purpose of turning on the vibration module 3, the smoking substrate will vibrate and become loose. This step can prevent the loosened smoking substrate from clogging the through-hole component 211.

[0080] In the control method of the heated cigarette smoking device, it is determined that a preset time has been reached; the vibration module 3 is turned on, and the vibration module 3 is turned off after a set time, so that the vibration module 3 is turned on after the preset time has been reached, so that the housing 21 and the cigarette vibrate, so that vibration can occur when the gap of the smoking substrate needs to be changed or the user needs to be reminded, so as to meet actual needs. Subsequently, the power of the airflow generator 5 is increased to prevent the loosened smoking substrate from blocking the through-hole component 211.

[0081] Embodiment 3

[0082] This embodiment provides another method for controlling a heated cigarette smoking article, which is implemented by the heated cigarette smoking article described above.

[0083] Reference Figure 4-Figure 5 The method for controlling the heated cigarette smoking device includes the following steps.

[0084] S200: Determine whether the user has finished the puffing action.

[0085] Step S200 includes the following steps.

[0086] S2001: Obtain the actual air pressure inside the accommodating chamber, and determine the difference between the actual air pressure and the set air pressure.

[0087] The actual air pressure inside the accommodating chamber can be obtained by a pressure sensor arranged in the accommodating chamber. The set air pressure is the normal air pressure that should be inside the accommodating chamber when the user does not inhale.

[0088] If the actual air pressure is less than the set air pressure, it indicates that the actual air pressure is less than the normal air pressure that should be in the accommodation chamber when no inhalation is performed, indicating that the user has started to inhale, and it is determined that the user is performing an inhalation action, and step S2002 is executed. If the actual air pressure is not less than the set air pressure, it indicates that the actual air pressure is not less than the normal air pressure that should be in the accommodation chamber when no inhalation is performed, indicating that the user has not started to inhale, and step S2001 is repeated at this time, that is, the actual air pressure in the accommodation chamber is obtained again, and the size of the actual air pressure and the set air pressure is determined.

[0089] S2002: repeatedly obtaining the actual air pressure inside the accommodation chamber, and determining the difference between the actual air pressure and the set air pressure.

[0090] If the actual air pressure is not less than the set air pressure, it indicates that the actual air pressure has returned to the normal air pressure that should be in the accommodation chamber when no suction is performed, indicating that the user is no longer performing the suction action, and thus it is determined that the user has ended the suction action. If the actual air pressure is less than the set air pressure, it indicates that the actual air pressure is still relatively small, indicating that the user is still in the state of suction, and step S2002 is repeated, that is, the actual air pressure in the accommodation chamber is repeatedly obtained, and the size of the actual air pressure and the set air pressure is determined.

[0091] As an alternative, a gas flow sensor disposed in the accommodating chamber can be used to detect the gas flow inside the accommodating chamber, and the normal gas flow inside the accommodating chamber when the user is not inhaling is used as the set flow. If the detected gas flow is greater than the set flow, it is determined that the user has started to inhale. At this time, the gas flow inside the accommodating chamber is repeatedly obtained. If the gas flow is not greater than the set flow, it is determined that the user has ended the inhalation action.

[0092] S210: Turn on the vibration module 3, and turn off the vibration module 3 after a set time.

[0093] After the user completes a puff, the vibration module 3 is turned on to vibrate the housing 21 and the cigarette, thereby changing the gap of the smoke-generating matrix and making the baking more complete and uniform.

[0094] S220: Increase the power of the airflow generator 5.

[0095] After the vibration module 3 is turned on, the smoking substrate will vibrate and become loose. This step can prevent the loosened smoking substrate from clogging the through-hole component 211.

[0096] In the control method of the heated cigarette smoking device, it is determined that the user has finished the puffing action; the vibration module 3 is turned on, and the vibration module 3 is turned off after a set time, so that after the user completes a puffing action, the vibration module 3 is turned on to vibrate the housing 21 and the cigarette, thereby changing the gap of the smoking substrate to make the baking more complete and uniform. Subsequently, the power of the airflow generator 5 is increased to prevent the loosened smoking substrate from blocking the through-hole component 211.

[0097] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
