[0001] The present application relates to the technical field of electronic heating appliances, and in particular to an electronic heating appliance and a control method thereof, a storage medium, and a computer program product. Background Art

[0002] Heating without burning is a technology that uses special heating equipment to heat special "cigarette cartridges" or "cigarette sticks" at low temperatures until they emit smoke, avoiding the toxic and harmful substances produced by high-temperature combustion, while being able to experience a taste and flavor close to that of cigarettes.

[0003] The heating-without-burning technology uses a circuit etched on a thin steel sheet and adheres the circuit to the outer wall of a metal tube. The heat is transmitted to the metal tube through a resistance wire, and then the cigarette is heated through the inner wall of the metal tube. However, in this technology, the part of the cigarette that needs to be heated is generally heated as a whole, resulting in slow heating efficiency. Summary of the invention

[0004] In this regard, the researchers first thought of using zone heating to heat the cigarette. However, the zone heating method results in inconsistent heating rates for each segment of the cigarette, which leads to inconsistent release rates of the smoking components of each segment of the cigarette. The smoking components of each segment are not completely released at the same time. Therefore, it is easy for a segment to be heated after the release of the components of the segment is completed, resulting in dry burning.

[0007] After it is identified that the smoke-generating substance of the first smoke-generating section is completely released, the first heating unit is controlled to stop working, and the second heating unit is started to work, so as to maintain the maximum temperature in the insertion channel within a first preset range.

[0008] In one embodiment, the electronic heating device includes a humidity detection device, and the humidity detection device is used to detect the humidity of the first smoking section of the cigarette. The control method also includes:

[0009] Whether the smoking substance in the first smoking segment is completely released is judged according to the humidity value of the first smoking segment of the cigarette.

[0010] In one embodiment, the step of judging whether the smokable substance of the first smoking segment is completely released according to the humidity value of the first smoking segment of the cigarette comprises:

[0012] When the first heating unit is working and the humidity change rate of the first smoking section is less than a second preset value, it is determined that the smoking substance of the first smoking section is completely released.

[0013] In one embodiment, before the step of identifying that the smoking substance of the first smoking segment has been completely released, the control method further includes:

[0014] The first heating unit and the second heating unit are correspondingly controlled to work alternately, so as to maintain the highest temperature in the insertion channel within a second preset range.

[0015] In one embodiment, the temperature value corresponding to the second preset range is smaller than the temperature value corresponding to the first preset range.

[0016] In one embodiment, the electronic heating device further comprises a smoke detection device, wherein the smoke detection device is used to detect the amount of smoke in the insertion channel, and the control method further comprises:

[0017] When the first heating unit is working and the change value of the smoke volume per unit time in the insertion channel is less than a third preset value, it is determined that the smoke-generating substance of the first smoke-generating section is completely released.

[0018] In one embodiment, before the step of identifying that the smoking substance of the first smoking segment has been completely released, the control method further includes:

[0019] When a heating instruction is received, the first heating unit is controlled to operate.

[0021] The control device is used to execute the steps of the control method of the electronic heating appliance as described in any one of the above.

Compared with the overall heating solution, since the heating rate of the first heating unit is slower and the local area is heated, the local temperature can be quickly increased, so that the local area of ​​the cigarette can quickly smoke, reducing the waiting time of the user between two puffs, and improving the user experience. Moreover, when it is identified that the content of the smoking substance in the first smoking segment is less than the first preset value, the first heating unit is controlled to stop working and the second heating unit is started to work, so as to maintain the highest temperature in the insertion channel within the first preset range, thereby effectively avoiding the first smoking segment from being continuously heated after the smoking substance in the first smoking segment is completely released, thereby avoiding the occurrence of dry burning.

The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0042] Heating without burning is a technology that uses a special heating device to heat a special "cigarette bomb" or "cigarette" at a low temperature until it emits smoke, avoiding the toxic and harmful substances produced by high-temperature combustion, while being able to experience a taste and flavor close to that of cigarettes. The heating without burning technical solution uses a thin steel sheet to etch a loop, and the loop is adhered to the outer wall of a metal tube. The heat is transmitted to the metal tube through a resistance wire, and then the cigarette is heated through the inner wall of the metal tube. However, in this technical solution, the heat-generating part of the cigarette is generally heated as a whole, resulting in a slow heating efficiency. When users use electronic heating devices to smoke electronic cigarettes, they need to wait for a long time after putting the cigarette into the electronic heating device before they can smoke, which results in a poor user experience.

[0043] See also Figures 2 to 7 An embodiment of the present application provides a heating module 10, including a heating component 20 and an isolating member 23, wherein the heating component 20 includes a first heating unit 21 and a second heating unit 22 arranged in sequence along a first direction, wherein a heating rate of the first heating unit 21 is higher than a heating rate of the second heating unit 22; the isolating member 23 is at least sleeved on the outer side of the heating component 20.

[0044] The embodiment of the present application divides the heating component 20 into a first heating unit 21 and a second heating unit 22, wherein the heating rate of the first heating unit 21 is higher than that of the second heating unit 22, so that when a user uses the electronic heating device 100 for inhalation, the cigarette 1 is placed into the electronic heating device 100, and when the heating component 20 is used for heating, the first heating unit 21 can be used to quickly heat up a part of the cigarette 1, and the heating component 20 can be insulated by the isolation member 23 to reduce the heat loss of the heating component 20, thereby quickly producing the first puff of cigarette and reducing the waiting time for the user for the first puff of cigarette. Compared with the overall heating solution, the solution of the present application has a fast heating rate and can quickly produce the first puff of cigarette for the user.

[0045] It should be noted that the first heating unit 21 and the second heating unit 22 are arranged sequentially in the first direction. The first heating unit 21 may be arranged closely in the first direction, or may be arranged at intervals, which is not limited here. The specific implementation form of the first heating unit 21 and / or the second heating unit 22 is not limited, and may be in the form of a heating net, a printed circuit, a carbon fiber heating element, etc., which is not limited here. The heating rate of the first heating unit 21 is higher than the heating rate of the second heating unit 22. The specific implementation form is not limited, and the heating power of the first heating unit 21 may be larger, or when the heating power of the first heating unit 21 and the second heating unit 22 are the same, the heating area of ​​the first heating unit 21 may be smaller, and so on, which is not limited here.

[0046] The heating rate refers to the length of time taken to heat the cigarette 1 from room temperature to the smoking temperature. For example, the longer the time taken to heat the cigarette 1 from room temperature to the smoking temperature, the slower the heating rate. Conversely, the shorter the time taken, the faster the heating rate.

[0047] The first heating unit 21 and the second heating unit 22 can be arranged in series or in parallel. When arranged in series, the two must be turned on or off at the same time. Therefore, in a further embodiment, the first heating unit 21 and the second heating unit 22 are arranged in parallel. Corresponding to the technical solution of this embodiment, by arranging the first heating unit 21 and the second heating unit 22 in parallel, the first heating unit 21 and the second heating unit 22 can be controlled independently of each other, and each can be independently turned on and off.

[0048] Furthermore, in one embodiment, the first heating unit 21 and the second heating unit 22 generate heat alternately. In this configuration, only one heating unit in the heating module 10 generates heat at a time, so that during the heating process, the power supply of the electronic heating device 100 only needs to supply power to one of the first heating unit 21 and the second heating unit 22. Correspondingly, the heating power of the first heating unit 21 and the second heating unit 22 can be made consistent with, or similar to, the heating power of the existing whole-section heating unit, so that the heating power that originally heated the entire section can now only heat a local part, thereby greatly improving the smoking efficiency of the cigarette 1.

[0049] Specifically, the initial resistance of the heating unit needs to be as small as possible while ensuring safety. For example, when using commonly used 18650 series batteries, the resistance can be configured to be between 0.4Ω and 1Ω.

[0050] Furthermore, the first heating unit 21 and the second heating unit 22 may be independently arranged, so that a short circuit between the first heating unit 21 and the second heating unit 22 can be effectively avoided.

[0051] In one embodiment, the first heating unit 21 has a first pin 211 and a second pin 212, and the second heating unit 22 has a third pin 221 and a fourth pin 222; wherein the first pin 211 and the third pin 221 are arranged at intervals, and the second pin 212 and the fourth pin 222 are arranged in an integrated manner.

[0052] In this configuration, since the second pin 212 and the fourth pin 222 are integrated, the two are connected together, and the resistance value at the corresponding pin is small, so that the heat generated at the pin is small, so that the heat can be concentrated on the part that needs to be heated.

[0053] Furthermore, in order to produce smoke more quickly and generate the first puff of smoke, the heating rate of the first heating unit 21 is more than twice the heating rate of the second heating unit 22, so that when the user uses the electronic cigarette, the first heating unit 21 can be used for heating first to quickly produce the first puff of smoke. After the first puff of smoke is produced, the first heating unit 21 and the second heating unit 22 can be heated alternately to heat different parts of the cigarette 1.

[0054] It should be emphasized that the heating rate of the first heating unit 21 is more than twice that of the second heating unit 22 , and the heating rate of the first heating unit 21 may be twice, three times, four times, etc., that of the second heating unit 22 .

[0055] Specifically, in one embodiment, the heating power of the first heating unit 21 and the second heating unit 22 are consistent, and the first heating unit 21 is a resistance wire. Correspondingly, at this time, the heating rate of the first heating unit 21 is the fastest.

[0056] In addition, the first heating unit 21 and the second heating unit 22 are not limited in the heating parts of the cigarette 1. One may heat the head of the part that needs to be heated of the cigarette 1, and the other may heat the tail of the cigarette 1. Specifically, the first heating unit 21 may heat the head of the part that needs to be heated of the cigarette 1, and the second heating unit 22 may heat the tail of the cigarette 1. Alternatively, the second heating unit 22 may heat the head of the part that needs to be heated of the cigarette 1, and the first heating unit 21 may heat the tail of the cigarette 1. There is no limitation here.

[0057] Please also read Figure 1 The cigarette 1 is divided into a smoking section, a cooling section and a filter section. The smoking section includes a first smoking section 11 and a second smoking section 12 close to the filter section. In one embodiment, when the heating component 20 is used to heat the cigarette 1, the first heating unit 21 is used to heat the portion of the cigarette 1 close to the cigarette holder, and the second heating unit 22 is used to heat the portion of the cigarette 1 away from the cigarette holder. With this arrangement, the portion heated by the first heating unit 21 is close to the cigarette holder. After smoking, the distance between the smoke and the cigarette holder is short, and the user can quickly inhale the smoke when inhaling. Specifically, the first heating unit 21 is used to heat the first smoking section 11, so that the first smoking section 11 smokes.

[0058] Furthermore, the specific implementation form of the heating component 20 is not limited, and it can be a heating net, a carbon fiber heating element, a printed circuit, etc. Specifically, the carbon fiber heating element is a tubular heating element made of carbon fiber as the basic heating material, which uses a reflective surface to dissipate heat, and the electric heat conversion rate is more than 95%, which saves 30% energy compared with nickel-chromium, tungsten-molybdenum and other materials as heating elements. When the isolation member 23 is a PI film, the heating component 20 can also be a printed circuit, so that the printed circuit is printed on the PI film, and the printed PI film is wrapped around the outside of the heat conductor to form the heating module.

[0059] In one embodiment, the heating component 20 includes a heating net, the first heating unit 21 includes a first heating net, and the second heating unit 22 includes a second heating net; wherein the first heating net includes a plurality of first resistance wires 213 arranged at intervals, and the second heating net includes a plurality of second resistance wires 223 arranged at intervals.

[0060] In the technical solution of this embodiment, by setting the first heating unit 21 as a first heating net, the second heating unit 22 as a second heating net, and each heating net including a plurality of resistance wires, the heating uniformity can be improved compared with the solution of a single resistance wire.

[0061] In a further embodiment, the gaps between the first resistance wires 213 are smaller than the gaps between the second resistance wires 223. With this configuration, the density of the resistance wires of the first heating unit 21 is greater, and the corresponding heating rate is also higher.

[0062] Alternatively, the cross-sectional area of ​​the first resistance wire 213 is smaller than the cross-sectional area of ​​the second resistance wire 223. In this configuration, the resistance value of the first resistance wire 213 is greater than the resistance value of the second resistance wire 223, thereby making the heating rate of the first heating unit 21 faster.

[0063] Furthermore, the width of the first resistance wire 213 is 0.2 to 2 mm, and the first resistance wire 213 is an austenitic stainless steel part. By setting it in this way, by limiting the width and material of the first resistance wire 213, the maximum heating temperature of the first resistance wire 213 can be limited, so that the maximum temperature of the first resistance wire 213 will not be too high, thereby avoiding scorching the cigarette 1 and affecting the quality of the smoke.

[0064] In addition, the heating module 10 also includes a heat-conducting tube 40, which has an insertion channel 41 suitable for inserting a cigarette 1; the heating component 20 is arranged on the outside of the heat-conducting tube 40; the isolation member 23 includes a heat-insulating film, which includes a first film segment 231 located between the heat-conducting tube 40 and the heating component 20 and a second film segment 232 located on the outside of the heating component 20; wherein the first film segment 231 surrounds the outside of the heat-conducting tube 40 for one week, and the second film segment 232 surrounds the outside of the heat-conducting tube 40 for at least three weeks.

[0065] In the technical solution corresponding to the present embodiment, the heating component 20 is arranged on the outside of the heat pipe 40, so that the heat emitted by the heating component 20 can be transferred to the cigarette 1 by the heat pipe 40 to heat the cigarette 1, and the heat pipe 40 can play the role of heat conduction and heat uniformity.

[0066] It is understandable that the heat pipe 40 can be a metal pipe or a plastic pipe, which is not limited here. When the heat pipe 40 is a metal pipe, by setting the first film segment 231, the first film segment 231 can play an insulating role between the heating component 20 and the heat pipe 40, thereby preventing the heating component 20 from being short-circuited by the heat pipe 40.

[0067] The first film segment 231 surrounds the outer side of the heat pipe 40, that is, only one layer of the heat insulating film is arranged between the heating component 20 and the heat pipe 40. While achieving insulation between the heating component 20 and the heat pipe 40, since only one layer is arranged, the influence on the heat transfer between the heating component and the heat pipe 40 is small.

[0068] The second film segment 232 surrounds the outer side of the heat pipe 40 at least three times, so that the second film segment 232 can form at least three layers of heat insulation on the outer side of the heating component 20, avoiding the heat generated by the heating component 20 from leaking out and reducing heat loss. The second film segment 232 has at least three layers. After the multi-layer winding, the heat insulation film can stand up in its width direction, which is convenient for subsequent assembly.

[0069] The heat-insulating film may be a PI film (polyimide film), which has good thermal conductivity, insulation, adhesion, and radiation resistance, and can be used for a long time within the temperature range of the smoking device.

[0070] See also Figure 5 During the manufacturing process, the heating component 20 can be first placed on the thermal insulation film, and the width of the heating component 20 is b; the thermal insulation film has a first length edge in its length direction; the distance between the heating component 20 and the first length edge is a; wherein a>b, during the rolling process, the heating component 20 and the first length edge form the first film segment 231, and the other parts form the second film segment 232.

[0071] The present application also provides an electronic heating device 100, which includes a heating module 10. The heating module 10 adopts a part of the technical solutions of the above embodiments, or all of the technical solutions, and thus has the technical advantages or all of the technical advantages of the above embodiments.

[0072] Heating without burning is a technology that uses special heating equipment to heat special "cigarette cartridges" or "cigarette sticks" at low temperatures until they emit smoke, avoiding the toxic and harmful substances produced by high-temperature combustion, while being able to experience a taste and flavor close to that of cigarettes.

[0073] The heating-without-burning technology uses a circuit etched on a thin steel sheet and adheres the circuit to the outer wall of a metal tube. The heat is transmitted to the metal tube through a resistance wire, and then the cigarette is heated through the inner wall of the metal tube. However, in this technology, the part of the cigarette that needs to be heated is generally heated as a whole, resulting in slow heating efficiency.

[0074] In this regard, the first thing that the R&D personnel thought of was to heat the cigarette using zoned heating. However, the zoned heating method results in inconsistent heating rates for each segment of the cigarette, which leads to inconsistent release rates of the smoking components of each segment of the cigarette. The smoking components of each segment are not completely released at the same time, especially the first smoking segment corresponding to the first heating unit, which is generally released in advance. Therefore, it is easy for a segment to be heated after the components of the segment are released, resulting in dry burning.

[0075] Based on this, the present application proposes a control method of the electronic heating device 100 according to the first embodiment. Figure 8 , the control method comprises:

[0076] Step S100: When it is identified that the content of the smoking substance in the first smoking section 11 is less than a first preset value, the first heating unit 21 is controlled to stop working, and the second heating unit 22 is started to work, so as to maintain the maximum temperature in the insertion channel 41 within a first preset range.

[0077] In the embodiment of the present application, the heating component 20 is divided into a first heating unit 21 and a second heating unit 22, wherein the heating rate of the first heating unit 21 is higher than that of the second heating unit 22, and after detecting that the user has finished puffing, the first heating unit 21 is controlled to work, so that the smoke required for the user's puffing can be quickly generated. Compared with the overall heating solution, since the heating rate of the first heating unit 21 is slower and the local area is heated, the local temperature can be quickly increased, so that the local area of ​​the cigarette 1 can quickly smoke, reduce the waiting time of the user between two puffs, and improve the user experience. Moreover, when it is identified that the content of the smoking substance in the first smoking segment 11 is less than the first preset value, the first heating unit 21 is controlled to stop working, and the second heating unit 22 is started to work, so as to maintain the highest temperature in the insertion channel 41 within the first preset range, so as to effectively avoid the first smoking segment 11 from being continuously heated after the smoking substance in the first smoking segment 11 is completely released, thereby avoiding the occurrence of dry burning.

[0078] As for the heat-conducting pipe 40, two short heat-conducting pipes may be respectively provided corresponding to the first heating unit 21 and the second heating unit 22, so that the first heating unit 21 heats up the first short heat-conducting pipe, and the second heating unit 22 heats up the second short heat-conducting pipe. Compared with the whole-tube heat-conducting solution, the local temperature rise rate is faster and the smoke generation rate is faster.

[0079] The detection of the user's suction action may be performed by detecting the change in gas pressure in the insertion channel 41 through a pressure sensor, or the pressure change caused by the user's hand movement, or by detecting temperature changes through a temperature sensor, or by detecting the gas flow rate in the input channel through an airflow sensor, etc., which are not limited here.

[0080] It should be emphasized that when the first heating unit 21 is working, the second heating unit 22 can be working or not working, and there is no limitation on this. In one embodiment, at most only one of the first heating unit 21 and the second heating unit 22 is working at the same time, so that when the parameters of the power supply are constant, the design power of the first heating unit 21 and the second heating unit 22 can be designed to the maximum power of the corresponding power supply.

[0081] It should be noted that the heating process of the electronic heating device 100 on the cigarette 1 can be roughly divided into a preheating stage, a middle stage and a tail stage. The preheating stage mainly refers to heating the temperature of the cigarette 1 inserted into the channel 41 to the smoking temperature, so that the cigarette 1 can smoke. The middle stage and the tail stage together constitute the user's inhalation stage. In the middle stage, the first smoking segment 11 is heated by the first heating unit 21, so that smoke can be quickly generated for the user to inhale. Correspondingly, in the tail stage, when the content of the smoking substance in the first smoking segment 11 is less than the first preset value, even if it is heated by the first heating unit 21, smoke cannot be quickly generated. The specific size of the first preset value is not limited, and it can be 10%, 20%, etc. of the maximum value of the smoking substance in the first smoking segment 11, or it can be 0, which is not limited here. The specific value of the first preset range is not limited, and it can be higher than the highest temperature of the middle stage, or it can be lower than the highest temperature of the middle stage, which is not limited here.

[0082] Further, the specific form of identifying that the content of the smokable substance of the first smokable segment 11 is less than or equal to the first preset value is not limited, and it can be to allow the user to make a judgment, and an operation unit is correspondingly set on the electronic heating device 100. After the user makes the judgment, the user operates the operation unit accordingly to allow the electronic heating device 100 to make the identification, or the electronic heating device 100 can make the identification by itself, which is not limited here. In one embodiment, after the step S100, the control method further includes:

[0083] Step S200: judging whether the content of the smokable substance in the first smoking segment 11 is less than or equal to a first preset value according to the humidity value of the first smoking segment 11 of the cigarette 1;

[0084] It should be noted that the content of the smoking substance in the first smoking section 11 is difficult to obtain directly. Therefore, the smoking substance generally includes ingredients such as nicotine, flavors and glycerin. The smoking substance is baked in the form of heating without burning. During the baking process, the humidity value of the smoking substance will change accordingly and gradually decrease.

[0085] Therefore, the content of the smoking substance in the first smoking segment 11 can be further judged by the humidity value of the first smoking segment 11 of the cigarette 1. Specifically, two electrode plates of a capacitor can be used, with the cigarette 1 load in the middle, which is equivalent to a medium. When the medium composition changes to a certain range, it is judged that the content of the smoking substance in the first smoking segment 11 is less than or equal to a first preset value. Alternatively, a humidity sensor can be directly used to detect the humidity of the cigarette 1 through the humidity sensor, so as to judge whether the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value.

[0086] In the technical solution corresponding to the present embodiment, by setting the humidity detection device, the humidity of the first smoking segment 11 of the cigarette 1 in the insertion channel 41 can be detected, and then it can be judged whether the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value according to the humidity value. When the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value, the first heating unit 21 can be controlled to stop working, and the second heating unit 22 can be started to work, so as to maintain the maximum temperature in the insertion channel 41 within the first preset range, thereby realizing that the electronic heating device 100 automatically judges the content of the smoking substance in the first smoking segment 11.

[0087] Specifically, the specific method of determining the content of the smokable substance in the cigarette 1 according to the humidity value is not limited. In one embodiment, the step S100 includes:

[0088] Step S110: when the humidity value is less than the second preset value, determining that the content of the smoking substance in the first smoking section 11 is less than or equal to the first preset value;

[0089] It can be understood that during the smoking process of the first smoking segment 11, its humidity gradually decreases. Therefore, when the humidity value is less than the second preset value, it can be determined that the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value. Specifically, the value of the second preset value can be measured according to the value of the first preset value. For example, when the first preset value is 10%, the second preset value is 11% humidity.

[0090] Alternatively, the step S100 includes:

[0091] Step S120: when the first heating unit 21 is working and the humidity change rate of the first smoking segment 11 is less than a third preset value, it is determined that the content of the smoking substance in the first smoking segment 11 is less than or equal to a first preset value.

[0092] It can be understood that the humidity change rate can be equivalent to the smoke generation amount to a certain extent. When the humidity change rate is greater, more smoke-generating substances are converted into smoke, and when the humidity change rate is smaller, the corresponding amount of smoke generation is smaller. Therefore, when the humidity change rate of the first smoking segment 11 is less than the third preset value, that is, when the smoke generation amount of the first smoking segment 11 is less than a certain value, it is determined that the content of the smoke-generating substance in the first smoking segment 11 is less than or equal to the first preset value.

[0093] Specifically, the value of the second preset value can be measured according to the value of the first preset value. For example, when the first preset value is 10%, the corresponding third preset value is a humidity change value of 1% per second.

[0094] In a further embodiment, before step S100, the control method further includes:

[0095] Step S90: correspondingly controlling the first heating unit 21 and the second heating unit 22 to work alternately, so as to maintain the temperature at different positions in the insertion channel 41 within a second preset range.

[0096] Corresponding to the scheme of this embodiment, during the process of the user smoking the electronic cigarette, the maximum temperature in the insertion channel 41 is maintained within the second preset range by adopting an alternating working mode, so that the temperature at different positions in the insertion channel 41 can be maintained within the second preset range, so that the smoking sections of the cigarette 1 are all within the same temperature range, so that the smoking rates of various parts of the cigarette 1 can be roughly the same, and the time difference for the complete release of the smoking substances in the first smoking section 11 and the second smoking section 12 can be minimized.

[0097] In addition, it should be emphasized that the values ​​of the first preset range and the second preset range are not restricted, as long as they are greater than the smoking temperature of cigarette 1. The first preset range and the second preset range can be designed to be the same range, or they can be different. When they are different, the temperature value corresponding to the first preset range can be less than the temperature value corresponding to the second preset range, or it can be greater than the temperature value corresponding to the second preset range, and no limitation is made here.

[0098] In a further embodiment, the temperature value corresponding to the second preset range is smaller than the temperature value corresponding to the first preset range. At this time, when it is identified that the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value, the second heating unit 22 is controlled to increase the temperature in the insertion channel 41 to a higher level, so that the second smoking segment 12 can generate more smoke, thereby ensuring the user's smoking experience even in the tail stage.

[0099] At the same time, the first preset value corresponds to 20 percent of the first smoking segment 11 when it is not burning. At this time, although the first heating unit 21 stops working, when the second heating unit 22 is working, part of the heat emitted by the second heating unit 22 can also be conducted to the first smoking segment 11 by the heat pipe 40, so that the first smoking segment 11 can also emit a small amount of smoke to compensate for the user's puffing. Compared with the solution of setting the first preset value to 0, it can effectively guarantee the amount of smoke in the end of the user's puffing and improve the user experience.

[0100] In addition, the consumption detection of the smoking substance of the cigarette 1 may also be that the electronic heating device 100 further includes a smoke detection device, the smoke detection device is used to detect the amount of smoke in the insertion channel 41, and the control method further includes:

[0101] When the first heating unit 21 is working and the change value of the smoke volume per unit time in the insertion channel 41 is less than the fourth preset value, it is determined that the content of the smoke-generating substance in the first smoking section 11 is less than or equal to the first preset value.

[0102] It can be understood that if the change value of the smoke volume per unit time in the insertion channel 41 is less than the fourth preset value, it can be considered that at this time, the smoke value emitted by the first smoking section 11 is less than the smoke value during normal heating. Therefore, it can be determined that the smoking substance of the first smoking section 11 has been almost released and can enter the tail section.

[0103] Corresponding to the present embodiment, when the first heating unit 21 is working and the change value of the smoke volume per unit time in the insertion channel 41 is less than the fourth preset value, that is, when the smoke volume generated by the first smoking segment 11 is significantly reduced, it is determined that the content of the smoking substance in the first smoking segment 11 is less than or equal to the first preset value.

[0104] Specifically, the specific implementation form of the smoke detection device is not limited, and it can be in the form of a pressure sensor. It can be understood that the different amounts of smoke in the insertion channel 41 correspond to different pressure values ​​in the insertion channel 41. Therefore, the pressure value in the insertion channel 41 can be detected by the pressure sensor, thereby detecting the amount of smoke in the insertion channel 41. In addition, it can also be in the form of a stable sensor. It can be understood that when the first heating unit 21 is heated, different amounts of smoke are generated, and correspondingly, the temperature values ​​in the insertion channel 41 are also different. When the amount of smoke is large, the smoke gathers, the heat does not diffuse, and the temperature value will be high. When the amount of smoke is small, the temperature value will also decrease. Therefore, it can also be determined by the temperature value in the insertion channel 41, and so on, which is not limited here.

[0105] Furthermore, before step S100, the control method further includes:

[0106] Step S10: upon receiving a heating instruction, controlling the first heating unit 21 to operate.

[0107] In the technical solution corresponding to the present embodiment, when a heating instruction is received, the first heating unit 21 is controlled to work, so that the first heating unit 21 can be used to heat the first smoking section 11 of the cigarette 1, thereby quickly generating the smoke required for the user to inhale, which can effectively shorten the user's waiting time.

[0108] Specifically, the timing of generating the heating instruction is not limited. The heating instruction may be generated when the user inserts the cigarette 1 into the insertion channel 41, thereby quickly preheating and producing the first puff of smoke inhaled by the user. The heating instruction may be generated after detecting that the user has finished puffing, thereby quickly generating the smoke required for the user's next puff.

[0109] The detection of the user's suction action may be performed by detecting the change in gas pressure in the insertion channel 41 through a pressure sensor, or the pressure change caused by the user's hand movement, or by detecting temperature changes through a temperature sensor, or by detecting the gas flow rate in the input channel through an airflow sensor, etc., which are not limited here.
