Description

Technical Field

[0001] This invention relates to the field of heating control technology, specifically to a temperature control method, device, heated non-combustible smoke appliance, and storage medium. Background Technology

[0002] Heated non-combustible devices are mostly used to heat cigarettes, causing them to produce aerosols.

[0003] Generally, heated tobacco products only use a continuous heating method to continuously heat the cigarette. During the time interval between the user smoking the cigarette, the cigarette continues to be heated at a high temperature to produce smoke, resulting in energy waste and unnecessary loss of aerosols generated inside the cigarette. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of energy waste and unnecessary loss of aerosol-generating substances in existing heated non-combustible tobacco devices due to their heating methods.

[0005] According to a first aspect, one embodiment provides a temperature control method applied to a heated non-combustible smoke appliance, comprising:

[0006] Get the current number of puffs of the current cigarette in the smoking device and record it as N, where N is a natural number;

[0007] Based on the current number of suctions N, the first heating temperature corresponding to the number of suctions N+1 is obtained from the pre-stored database;

[0008] Detect whether the user is making a suctioning motion;

[0009] If so, the heating temperature of the smoking device is controlled to change to the first heating temperature;

[0010] During the first time period after the user finishes the suction action and before the next suction action is detected, the heating temperature is controlled to be maintained at the first heating temperature.

[0011] During the second time period after the user finishes the inhalation action and before the next inhalation action is detected, the cigarette is heated to a second heating temperature determined according to a preset first temperature-time change curve, wherein the maximum value of the first temperature-time change curve is the first heating temperature and the minimum value is the third heating temperature.

[0012] During the third time period after the user finishes the suction action and before the next suction action is detected, the heating temperature is controlled to be maintained at the third heating temperature.

[0013] According to a second aspect, one embodiment provides a temperature control device applied to a heated non-combustible smoke appliance, comprising:

[0014] The acquisition module is used to acquire the current number of puffs of the current cigarette in the smoking device, and record it as N, where N is a natural number;

[0015] The retrieval module is used to obtain the first heating temperature corresponding to the N+1th suction count from the pre-stored database based on the current suction count N.

[0016] The monitoring module is used to detect whether the user is making a suction motion;

[0017] The first control module is used to control the heating temperature of the smoking device to change to the first heating temperature if the user makes a sucking motion.

[0018] The second control module is used to control the heating temperature to be maintained at the first heating temperature during a first time period after the user ends the suction action and before the next suction action is detected.

[0019] The third control module is used to heat the cigarette at a second heating temperature determined by a preset first temperature-time change curve during a second time period after the user finishes the inhalation action and before the next inhalation action is detected. The maximum value of the first temperature-time change curve is the first heating temperature, and the minimum value is the third heating temperature.

[0020] The fourth control module is used to maintain the heating temperature at the third heating temperature during the third time period after the user ends the suction action and before the next suction action is detected.

[0021] According to a third aspect, one embodiment provides a heated non-combustible smoke appliance, including a heating element, a heating chamber, and a temperature control device described in the second aspect above;

[0022] The heating chamber has space for installing cigarettes;

[0023] The heating element is configured to heat the cigarette.

[0024] According to a fourth aspect, one embodiment provides a computer-readable storage medium storing a program that can be executed by a processor to implement the method as described in the first aspect.

[0025] Based on the temperature control method, temperature control device, heated non-combustible tobacco device, and storage medium described in the above embodiments, the current number of puffs of the current cigarette in the device is obtained. After the user finishes puffing, different heating temperatures are applied according to the length of the time interval between two puffs. When the user does not need to puff or heat atomize, or when the interval between two puffs is long, a lower second or third heating temperature is used for heat preservation to ensure that the cigarette is in a low-temperature heating state, avoiding unnecessary high-temperature heating loss of the cigarette. At the same time, when the next puff or heating atomization is needed, the temperature can be quickly raised for atomization, which can give the user a good smoke effect, extend the service life of the cigarette, and save energy consumption of the device.

[0033] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] Existing heat-not-burn devices, such as heat-not-burn smoking devices, generate smoke by heating a cigarette stick; this process of smoke generation can also be called atomization. The quality of the smoke generation directly affects the user experience, such as the taste. Furthermore, when a solid cigarette stick is heated to a first preset temperature or higher under normal pressure, it will atomize to produce smoke (aerosol vaporization). The first preset temperature can be defined as the atomization temperature or vaporization temperature.

[0037] Taking heated tobacco products as an example, the existing heating methods generally adopt a single heating temperature for continuous heating. The cigarette in the heated tobacco product is in a state of continuous high-temperature heating and atomization. On the one hand, it consumes electrical energy, and the heated tobacco product needs to be recharged repeatedly. On the other hand, it wastes the aerosol generated in the cigarette, and the cigarette wears out too quickly, increasing the frequency of users replacing the cigarette and resulting in a poor user experience.

[0038] The applicant's research found that heating the cigarette can be controlled only when the user needs to atomize and generate smoke. For example, in this application's embodiment using a heated non-combustible tobacco device, the cigarette is heated only when the user is inhaling. When not smoking, the cigarette can be heated at a higher temperature to atomize the aerosol-generating substances inside, producing enough smoke for the user's next inhalation. Then, a lower temperature is used to maintain the temperature. This reduces unnecessary loss of aerosol-generating substances within the cigarette, and ensures that the user inhales sufficient aerosol the next time they inhale. Furthermore, the device can quickly heat up to atomize the aerosol-generating substances at a higher temperature, producing enough smoke for the user's next inhalation, thus creating a cycle.

[0039] like Figure 1 and Figure 2 As shown, one embodiment provides a temperature control device and a heated non-combustible smoke appliance, the heated non-combustible smoke appliance including: a heating element 20, a heating chamber 10 and a temperature control device 30.

[0040] The heating chamber 10 has space for mounting the cigarette. For example, the heating chamber 10 can be made of a high-temperature resistant material such as ceramic or metal.

[0041] The heating element 20 is configured to heat the cigarette. In some embodiments, the heating element 20 may be disposed inside the heating chamber 10, in direct contact with the outside of the cigarette. In some embodiments, the heating element 20 may be disposed on the outer wall of the heating chamber, first heating the heating shell, and then heating the cigarette through the heating shell.

[0042] In one embodiment, the heating element 20 may include a heating tube and a coil, the coil being configured to heat the heating tube via electromagnetic induction, and the heating tube contacting the side wall of the heating chamber 10; the heating tube is sleeved on the inner or outer wall of the heating chamber 10. In some embodiments, the heating element 20 may be a resistive heating element 20, disposed on the inner or outer wall of the heating chamber 10. Using electromagnetic induction eliminates the need for a circuit connection to the heating tube, allowing it to be sleeved on the inner wall of the heating chamber 10 for direct contact with the cigarette, enabling rapid and effective heating.

[0043] The temperature control device 30 may include an acquisition module 31, a retrieval module 32, a monitoring module 33, a first control module 34, a second control module 35, a third control module 36, and a fourth control module 37. Each of these modules may be a single functional module implemented using a processing chip, or multiple modules may be implemented using the same processing chip.

[0044] The acquisition module 31 is used to acquire the current number of puffs of the current cigarette in the smoking device, and denoted as N, where N is a natural number.

[0045] The retrieval module 32 is used to obtain the first heating temperature corresponding to the N+1th suction count from the pre-stored database based on the current suction count N.

[0046] The monitoring module 33 is used to detect whether the user is making a suctioning motion.

[0047] The first control module 34 is used to control the heating temperature of the smoking device to change to a first heating temperature if the user performs a sucking action.

[0048] The second control module 35 is used to control the heating temperature to remain at a first heating temperature during a first time period after the user ends the suction action and before the next suction action is detected.

[0049] The third control module 36 is used to heat the cigarette at a second heating temperature determined by a preset first temperature-time change curve during a second time period after the user ends the inhalation action and before the next inhalation action is detected. The maximum value of the first temperature-time change curve is the first heating temperature, and the minimum value is the third heating temperature.

[0050] The fourth control module 37 is used to maintain the heating temperature at a third heating temperature during a third time period after the user ends the suction action and before the next suction action is detected. The temperature control device uses the temperature control method provided in this application to control the heating component 20 to operate.

[0051] The following describes the specific process of temperature control using a temperature control device, taking a heated non-combustible tobacco appliance as an example. The heated non-combustible tobacco appliance has a heating element for heating the tobacco stick, such as... Figure 3 As shown, the temperature control method includes the following steps:

[0052] Step 0: Detect whether the user has triggered the command to start the heating of the smoke-emitting device.

[0053] For example, the smoking device may include touch buttons, buttons, or voice-activated switches. When a user needs to use the smoking device, they can trigger these start switches to activate the heating function, which means that the user has performed a power-on operation, indicating that the user needs to use the smoking device.

[0054] Step 1: Obtain the current number of puffs of the current cigarette in the smoking device and record it as N, where N is a natural number.

[0055] For example, sensors that detect the cigarette, such as pressure sensors or infrared sensors, can be installed on the smoking device. After the cigarette is installed, airflow sensors, temperature sensors, etc., can record the number of puffs taken by the user to determine the current number of puffs. For instance, using a temperature sensor to record the user's puffing actions, since airflow passes through the heating element of the heating component during puffing, the air pressure around the heating element changes, and consequently, the temperature of the heating element changes. Therefore, detecting the temperature change of the heating element can determine whether the user has taken a puff. When the user removes the cigarette and installs a new one, the current number of puffs is recorded as 0.

[0056] Step 2: Obtain the first heating temperature corresponding to the N+1th suction count from the pre-stored database based on the current suction count N.

[0057] Cigarettes can be of multiple types or only one type. Different types of cigarettes have different heating and atomization temperatures, and the smoking device uses different heating curves for different types of cigarettes. In this step, the smoking device can be used for only one type of cigarette, in which case it is only necessary to pre-set the heating curve corresponding to that cigarette in the smoking device; if the smoking device is suitable for multiple types of cigarettes, then it is necessary to pre-store multiple heating curves for different types of cigarettes in the smoking device. Among them, these heating curves are in one-to-one correspondence with the number of puffs. For example, the first puff corresponds to a heating temperature, the second puff corresponds to a heating temperature.

[0058] In one embodiment, the maximum number of times the cigarette can be smoked is M, where M is a positive integer, and the first heating temperature corresponding to each number of smokes is T. 11 T 12 …T 1M The number of puffs corresponding to the first heating temperature can be increased first, then decreased, and then increased, or there can be no size limit. It can be set according to the type of cigarette and the smoking device itself.

[0059] Taking a cigarette as an example, the initial inhalation or heating for vaporization requires raising the temperature from room temperature to the vaporization temperature. Given a short inhalation time, rapid heating is necessary, so the initial heating temperature needs to be relatively high. In subsequent inhalations (such as the second inhalation), the cigarette still contains a significant amount of vapor, and having undergone the first heating cycle, it can be heated at a relatively lower initial temperature. In the final inhalation, the amount of vaporizable vapor is relatively small, requiring a higher temperature to ensure sufficient vapor production for the user. Therefore, different inhalations require different initial heating temperatures. By using different initial heating temperatures for different inhalations while maintaining sufficient vaporization, a better vaporization effect can be achieved.

[0060] In one embodiment, the cigarette can be smoked a maximum of four times, and the first heating temperature corresponding to the four smoke counts can be T. 11 T 12 T 13 And T 14 Among them, T 11 ≥T 12 And T 14 ≥T 13 T 11 ≥T 12 or T 12 ≥T 11 For example, T 11 =300℃, T 12 =260℃, T 13 =280℃ and T 14 =290℃.

[0061] Step 201: After step 2, the cigarette is heated based on the preset preheating temperature curve.

[0062] In one embodiment, the initial temperature of the smoking device is low when the user turns it off before the first use or after finishing smoking. This embodiment addresses this by preheating the device to a first heating temperature corresponding to the current number of puffs after the user turns it on. For example, the temperature T required for the first puff is... 11 =300℃. Before detecting a user's inhalation, the cigarette is preheated according to the preheating temperature curve to ensure that the required temperature T is quickly reached when the user takes their first puff. 11 Each suction cycle can have its own preheating temperature curve, or multiple suction cycles can use the same preheating temperature curve, which can be set according to actual needs.

[0063] Step 202: After step 1, determine whether the current number of puffs N is less than the maximum number of puffs M that the current cigarette can be puffed.

[0064] If not, a warning will be issued and / or the device will stop heating. For example, the warning could be a vibration, a flashing indicator light, or a combination of both, to remind the user to replace the cigarette or stop smoking.

[0065] If so, proceed to step 3.

[0066] For example, the maximum number of times a cigarette can be smoked can be determined based on the cigarette's information. Different sizes of cigarettes require corresponding matching heated tobacco products. The number of times a cigarette can be smoked is usually provided by the cigarette manufacturer, or it can be determined through a limited number of experiments. Therefore, the maximum number of times a cigarette can be smoked can be obtained from the cigarette's information, such as manufacturer information, model information, or experimental information. Once the maximum number of smokes has been reached, the heated tobacco product can be turned off.

[0067] Step 3: Detect whether the user is making a suctioning motion.

[0068] In one embodiment, at least one sensor, including a pressure sensor, a temperature sensor, a flow sensor, an airflow sensor, and a noise sensor, can be installed inside the smoking device to detect whether the user is sucking.

[0069] Alternatively, touch buttons can be set up so that users can control the heating element to work when they need to smoke the device, and record the number of times the user smokes.

[0070] For example, when a user uses a heated tobacco product, after installing a new cigarette and turning it on, the system can collect information such as pressure, temperature, airflow, gas, and noise generated by the user's inhalation to determine if the user is inhaling the heated tobacco product. This information then generates a suction control command, which triggers the temperature control device 30 to activate the heating element. Alternatively, a touch-sensitive button can also be used to generate the suction control command.

[0071] Step 4: If the user sucks, control the heating temperature of the smoking device to change to the first heating temperature.

[0072] During the first time period after the user finishes the suction action and before the next suction action is detected, the heating temperature is controlled to be maintained at the first heating temperature.

[0073] During a second time period after the user finishes inhaling and before the next inhalation is detected, the cigarette is heated to a second heating temperature determined according to a preset first temperature-time change curve, wherein the maximum value of the first temperature-time change curve is the first heating temperature and the minimum value is the third heating temperature.

[0074] During the third time period after the user finishes the suction action and before the next suction action is detected, the heating temperature is controlled to be maintained at the third heating temperature.

[0075] In step 4, between different number of puffs, the actual temperature of the cigarette may gradually decrease to the first heating temperature or rise to the first heating temperature, depending on the time interval between the user's puffs and the heating temperature corresponding to different number of puffs.

[0076] Based on the current number of puffs, the required heating temperature T is determined and the cigarette is heated. After the user finishes puffing, heating and heat preservation are performed according to the duration between the user's last puff and the detection of the next puff. After heating begins through the heating element, the temperature is controlled in stages during the duration between the current puff and the next puff. For example, if the time interval between the second and third puffs is 10 seconds, then the duration after the second puff ends is 10 seconds. This 10-second interval can be divided into three time periods, within which a preset heating temperature or temperature curve is used for heating.

[0077] In one embodiment, such as Figure 4 As shown, there are two cases: the last puff and other puffs. If the current puff count N is equal to the number of times the cigarette can be puffed M, when the last puff triggers the heating element to work, the temperature control device controls the heating temperature of the cigarette device to change to the first heating temperature, triggers the shutdown command, and the temperature control device shuts down. There is no heating in the subsequent three time periods.

[0078] During the final suction, the machine is heated to the first heating temperature until the user finishes suctioning, after which it is turned off.

[0079] In other suction cycles, after detecting that the user has finished the current suction action, heating is performed at the first heating temperature during the first time period. For example, if the first time period is 0 to 2 seconds, heating is performed directly at the first heating temperature for 2 seconds.

[0080] During the second time period, a preset first temperature-time variation curve is used to determine the second heating temperature corresponding to the duration, and heating is performed accordingly. The maximum value of the first temperature-time variation curve is the first heating temperature, and the minimum value is the third heating temperature. The third heating temperature is lower than the atomization temperature of the cigarette and higher than the condensation temperature of the cigarette. For example, if the second time period is 2 to 10 seconds, the second heating temperature is used for heating, and the second heating temperature is a temperature that varies with the duration.

[0081] During the third time period, heating is performed at the third heating temperature. The first, second, and third time periods are consecutive time periods.

[0082] In one embodiment, during the second time period, the second heating temperature may be negatively correlated with the duration.

[0083] For example, during the second duration, the second heating temperature is determined using the following formula:

[0084] T2 = T1 - k × t;

[0085] Where T1 is the first heating temperature, T2 is the second heating temperature, k is a constant, and t is the duration after the user ends the suction action and before the next suction action is detected.

[0086] In one embodiment, k = (T1 - T3) / t2. Where T3 is the third heating temperature, the first time period is 0 < t ≤ t1, the second time period is t1 < t ≤ t2, and the third time period is t2 < t.

[0087] As can be seen, after each suction action, the duration is recorded starting from zero, and each suction count can be divided into time periods according to t1 and t2. The t1 and t2 values ​​for each suction count can be the same or different. For example, t1 can be greater than or equal to 2 seconds, and t2 can be greater than or equal to 5 × t1.

[0088] For example, the maximum number of times a cigarette can be smoked, M, is four times, and the first heating temperature corresponding to the four number of smokes is T. 11 T 12 T 13 And T 14 T 11 =300℃, T 12 =260℃, T 13 =280℃ and T 14 =290℃. t1 = 2 seconds, t2 = 10 seconds. For example... Figure 5 As shown, the first heating temperature T1 = T corresponding to the second suction number is... 12 =260℃, T3 = 200℃. It can be seen that, corresponding to the second suction cycle, after the first suction cycle ended, the temperature was maintained at T3. Therefore, at the start of the second suction cycle, the temperature could be rapidly increased to T. 12 .

[0089] During the first time period, heating is performed at 260°C.

[0090] During the second time period, based on the duration t after the suction ends, the second heating temperature T2 = T1 - (T1 - T3) ÷ t2 × t = 260℃ - (260℃ - 200℃) ÷ 10S × t = 260℃ - 6℃ × t. When the duration t = 5S, the corresponding heating temperature is 230℃.

[0091] During the third time period, heating was carried out at 200℃.

[0092] Similarly, when a user takes a third puff after a relatively long interval after the second puff, the device maintains a temperature that prevents condensation, thus avoiding the burning of more of the smoke-generating substances in the cigarette. This enhances the uniformity of each puff and increases the number of puffs, while also reducing energy consumption. In other words, the third heating temperature is higher than the condensation temperature of the smoke, thereby preventing the condensation from affecting the normal use of the device.

[0093] If the interval between two inhalations is long, the device is kept warm at a third heating temperature that is not lower than the condensation temperature but lower than the atomization temperature. The substances in the cigarette are in an intermediate state between condensation and atomization. When the user inhales again, the air pressure inside the heated non-combustible device decreases and the temperature increases, allowing the cigarette to atomize quickly and produce smoke rapidly.

[0094] In one embodiment, such as Figure 5 As shown, the frequency at which the user inhales the heated non-combustible tobacco device is not fixed; that is, the time interval between each two inhalations is different, and the duration after each inhalation is also different. Therefore, heating for three time periods is not performed after each inhalation.

[0095] like Figure 6 As shown, if the user triggers a control command for a third puff within the second time period after the second puff, the heating process begins at the temperature corresponding to the third puff count. The cigarette is then heated from T3 to T... 13 The time required is significantly longer than heating from T2 to T. 13 The required time. Therefore, a second time period temperature control is introduced to better meet the user's smoking needs without a fixed frequency. In this application, the third heating temperature corresponding to each number of puffs can be the same or different; this application embodiment uses the same temperature as an example for illustration.

[0096] During the second time period, depending on the instantaneous time point of the duration, the temperature of the cigarette after being heated in the first time period will be different. Different second heating temperatures will be used to gradually reduce the temperature of the cigarette so that when the user makes a third inhale, the cigarette can heat up quickly and provide a better smoke effect.

[0097] In other words, except for the first suction, the start time of other suction cycles can be within the second or third time period after the end of the previous suction action, which can accelerate the atomization efficiency of the current suction cycle. Therefore, preheating can be performed using step 201 before the first suction.

[0098] Step 5: After step 4, if the duration between when the user finishes the inhalation action and when no next inhalation action is detected is longer than a preset time, the device will be controlled to stop working.

[0099] For example, corresponding to t1 = 2 seconds and t2 = 10 seconds, in the third time period after the user finishes the inhalation action and before the next inhalation action is detected, if the duration of maintaining the heating temperature at the third heating temperature is detected to be greater than 1 minute, it can be considered that the user no longer needs to use the smoking device, and the device can stop working. At this time, the preset time t3 = 1 minute. That is to say, the third time period is t2 < t < t3.

[0100] In this embodiment, the current number of puffs of the cigarette in the smoking device is obtained. When the user does not need to puff or heat atomize, or when the interval between two puffs is long, the device is heated and kept warm at a lower second or third heating temperature to ensure that the cigarette is in a low-temperature heating state. This avoids unnecessary high-temperature heating loss of the cigarette. At the same time, when the user needs to puff or heat atomize again, the device can quickly heat up and atomize, which can give the user a good smoke effect, extend the service life of the cigarette, and save energy consumption of the smoking device.

[0101] In addition, this application also provides a heated non-combustible smoke appliance, which includes the temperature control device described in the above embodiments.
