[0028] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0029] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0030] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0031] As shown in Figure 1, existing heat-not-burn smoking devices can be implemented by inserting a heating needle into an aerosol-generating matrix to heat and generate smoke. The heating needle generally has a housing and a heating wire within the housing. As shown in Figure 2, the two ends of the existing heating wire are electrically connected via connecting wires, and its heating range or heating temperature zone is fixed.

[0032] With the widespread use of e-cigarettes, users have increasing demands for faster smoke output, more efficient use, and longer usable time. This requires e-cigarettes to have increasingly diverse heating functions. Currently, the heating method using a heating wire, as shown in Figure 2, is limited in its heating method and is difficult to meet customer needs.

[0033] In the embodiment of the present application, by adding at least one additional lead in the area between the two ends of the heating wire, the corresponding two leads can be connected according to different heating requirements to achieve different heating methods and heating temperature zones, so that the smoking device has richer heating functions to meet the user's usage needs.

[0034] Example 1

[0035] As shown in FIG3 and FIG4 , an embodiment of the present application provides a heating component 100 for use in heat-not-burn smoking devices. The heating component 100 is configured to be inserted into an aerosol-generating substrate mounted on the smoking device to heat the aerosol-generating substrate.

[0036] The heating component 100 may include a heating wire 10 and at least three leads. The heating wire 10 extends forward along a first preset direction (the left and right directions as shown in Figures 3 and 4) and then extends in the reverse direction. The first end 11 and the second end 12 of the heating wire 10 are located on the same side.

[0037] The at least three leads may include a first lead 21 , a second lead 22 , and at least one additional lead 23 .

[0038] The first lead 21 is electrically connected to the first end 11 of the heating wire 10 , and the second lead 22 is electrically connected to the second end 12 of the heating wire 10 . The additional lead 23 is electrically connected between the first end 11 and the second end 12 of the heating wire 10 .

[0039] The heating component 100 provided in the present application has multiple leads, and any two leads can be selected for electrical heating to achieve heating of different areas or heating with different powers.

[0040] In some embodiments, as shown in FIG. 3 and FIG. 4 , the heating wire 10 is arranged in a double helix along a first preset direction. The heating wire 10 arranged in a helical manner heats the circumference more evenly.

[0041] For ease of description, taking the additional lead 23 as an example, the first lead 21 can be represented by symbol A, the second lead 22 can be represented by symbol B, and the additional lead 23 can be represented by symbol P.

[0042] In some embodiments, the distance along which the heating wire 10 extends forward along the first predetermined direction is the first distance, and the total length of the heating wire 10 is the first length. An additional lead 23 may be connected near the first end 11, and the length of the heating wire 10 between the connection point and the first end 11 is 20%-30% of the first length. The resistance between the first end 11 and the connection point is less than the resistance between the second end 12 and the connection point.

[0043] For example, as shown in Figure 3, an additional lead 23 is connected to the heating wire 10 at a point ¼ the length near the first end 11. At this point, the distance between the first end 11 and the connection point is half the first distance. When the AP leads are energized, the heating zone is shown in the dashed box in Figure 5 (A), heating the left half of the area. At this point, the resistance in the circuit is ¼R, where R is the resistance of the heating wire 10. By varying the voltage or current in the AP leads, this area can be heated to varying powers. When the BP leads are energized, the heating zone is shown in the two dashed boxes in Figure 5 (B). The heating area is the same as when the AB leads are energized, but the heating density in the left dashed box is lower than that in the right dashed box. At this point, the resistance in the circuit is ¾R, where R is the resistance of the heating wire 10. The resistance in the left dashed box is ¼R, while the resistance in the right dashed box is ½R. By varying the voltage or current in the BP leads, these two areas can be heated to varying powers.

[0044] In another embodiment, the distance along which the heating wire 10 extends forward in the first predetermined direction is the first distance, and the total length of the heating wire 10 is the first length. An additional lead 23 may be connected near the middle region, and the length of the heating wire 10 between the connection point and the first end 11 is 40%-60% of the first length. The resistance between the first end 11 and the connection point is substantially equal to the resistance between the second end 12 and the connection point.

[0045] For example, as shown in Figure 4, an additional lead 23 is connected at half the length of the heating wire 10. In this case, the distance between the first end 11 and the connection point is half the first distance. When the AP leads or the BP leads are energized, the heating area is the same as when the AB leads are energized. At this point, the resistance in the connected circuit is 1 / 2R, where R is the resistance of the heating wire 10. Compared to energizing the AB leads, energizing the AP leads or the BP leads can achieve different heating power levels without changing the input voltage or current.

[0046] In some embodiments, the heating component 100 may further include a ceramic inner core (not shown), which is engraved with grooves. The grooves can guide the heating wire 10 for spiral winding and can separate multiple strands of the heating wire 10.

[0047] In some embodiments, as shown in Figures 3 and 4 , the spiral heating wire 10 has a hollow region, and an additional lead 23 can be inserted through the hollow region to electrically connect to the heating wire 10. In this case, the ceramic core can be a hollow ceramic tube, and the additional lead 23 can extend through the hollow region of the ceramic tube and electrically connect to the heating wire 10.

[0048] This wiring method can reduce the space occupied by the heating wire 10 and the lead wire, and effectively control the volume of the heating component 100 (specifically, the radius of the heating needle).

[0049] In some embodiments, the temperature coefficient of resistance (TCR value) of the heating wire 10 is greater than or equal to 700 ppm / °C.

[0050] When the resistance temperature coefficient of the heating wire is large (for example, greater than or equal to 700ppm / °C), the following technical effects can be achieved:

[0051] Good temperature stability: A high temperature coefficient of resistance means that the resistance of the heating wire 10 changes greatly with temperature, which helps to maintain a stable resistance value at different temperatures.

[0052] Fast temperature response: The heating wire 10 with a large resistance temperature coefficient can quickly respond to temperature changes, thereby adjusting the resistance value more quickly and improving the sensitivity and accuracy of temperature control.

[0053] Precise temperature control: By utilizing the high temperature coefficient of resistance, more precise temperature control can be achieved, allowing the heating wire to provide stable heating effects at different temperatures.

[0054] For example, the heating wire 10 may be made of titanium, an iron-nickel alloy, or stainless steel. These materials have high TCR values, can meet the requirements of the above-mentioned embodiment, and are also suitable materials for the heating wire 10. Furthermore, these materials are chemically stable and not easily oxidized, allowing for long-term heating use.

[0055] In some embodiments, the material of the lead wire may be nickel, silver, nickel alloy, silver alloy, nickel-clad copper composite material, or copper-clad nickel composite material.

[0056] Leads made of the above materials can have good electrical conductivity and are suitable for current transmission requirements. They also have certain corrosion resistance, which can resist oxidation and chemical corrosion to a certain extent, maintaining the stability of the lead. They have good mechanical properties and can withstand certain stretching and bending, making them suitable for applications requiring high mechanical strength. They have stable electrical properties within a certain temperature range, which can maintain the electrical characteristics of the lead without being affected by the external environment, facilitating precise temperature control of the heating wire 10.

[0057] In some embodiments, the heating component 100 may further include a shell, which is mounted on the outside of the heating wire 10, and the lead is at least partially exposed outside the shell; the shell may be made of an insulating material, or the inside of the shell may have an insulating layer.

[0058] For example, the outer shell of the ceramic tube is not limited to YSZ (yttria reinforced zirconia ceramic) or ZTA (zirconia toughened alumina), and can also be a metal tube with an inner wall coated or provided with an insulating material or with an inner wall subjected to insulation treatment.

[0059] In some embodiments, the heating component 100 may further include an insulating material, and the insulating material is used to isolate the multiple leads from each other and / or to isolate the leads from the heating wire 10 .

[0060] For example, an insulating material may be filled inside the housing, such as ceramic powder, which may isolate the lead wire from the heating wire 10 and also isolate the leads from each other.

[0061] For another example, the leads are isolated with insulating materials (such as glass capillary sleeves or ceramic capillary sleeves, or ceramic inorganic gelled materials, or other inorganic non-metallic insulating powder materials) to prevent short circuits.

[0062] Example 2

[0063] As shown in FIG6 , the embodiment of the present application further provides a heat-not-burn smoking device, which may include: a control device 200 and the heating component 100 described in the above embodiment 1.

[0064] The control device 200 is configured to control the heating of the heating component 100 according to the heating control method described in the embodiment of the present application.

[0065] The specific process of the heating control method of the heat-not-burn smoking device / control device 200 is explained below. As shown in Figure 7, the heating control method provided in the embodiment of the present application is applied to the above-mentioned heat-not-burn smoking device. The smoking device may include the heating component 100 described in Example 1. The heating component 100 is configured to be inserted into the interior of the aerosol generating substrate installed on the smoking device to heat the aerosol generating substrate.

[0066] Heating control methods may include:

[0067] Step 1: Obtain a mode selection instruction. When triggered by the mode selection instruction, control the smoking device to adopt a corresponding heating mode to control the heating component 100 to heat.

[0068] For example, the smoking device may be provided with a touch unit of a button or a touch screen, and the user generates a mode selection instruction through the touch unit, and the control device 200 selects the required heating mode according to the mode selection instruction.

[0069] Step 2: According to the current heating mode, the heating component 100 is controlled to energize the two leads in the heating component 100 in a corresponding energizing manner in each heating stage to control the heating component 100 to heat.

[0070] Among them, the heating mode may include at least two heating modes; the heating mode may include multiple heating stages; in one heating mode, the power-on mode between at least two heating stages is different; between two heating modes, the power-on mode of at least one heating stage is different.

[0071] The smoking device can be configured with various heating modules (or operating modes) to meet the user's smoking needs. For example, a user may need to finish a cigarette quickly, require a longer puff with less smoke per puff, or require a more balanced puff pattern. These different heating requirements require the heating component 100 to use corresponding heating power and heating area to heat the aerosol-generating substrate.

[0072] Within the same heating mode, different smoke / heating requirements are also required at different stages. For example, in the initial heating phase, the cigarette temperature is relatively low, and the user often requires a larger amount of smoke or a faster smoke output during the first puff. This requires a higher heating power. Another example is that in the final stage of the puff, the aerosol-generating substrate content in the cigarette is already low, or local heating is uneven. At this time, overall heating is required to fully heat the remaining aerosol-generating substrate.

[0073] As shown in Figure 8, an embodiment of the present application provides a heating component 100, which can be provided with at least one additional lead 23. In combination with the first lead 21 and the second lead 22, two leads are selected from multiple leads to be energized (such two energized leads are defined as a group of leads), which can achieve different heating powers and heating of different areas.

[0074] Therefore, in different heating stages, a single set of leads can be energized for heating, or multiple sets of leads can be alternately energized for heating to achieve different heating functions and meet the heating requirements of each heating stage. Different heating modes have different heating stages, so the selectability and combination of multiple sets of leads can also meet the heating requirements of different heating modes.

[0075] In some embodiments, the multiple heating stages may include an initial heating stage.

[0076] In step 2, controlling the heating component 100 to energize the two leads of the heating component 100 using a corresponding energizing method in each heating stage may include:

[0077] Initial heating: During the initial heating stage, one of the first lead 21 and the second lead 22 and one additional lead 23 are controlled to be energized.

[0078] Subsequent heating, after completing the initial heating stage, enters the next preset heating stage. According to the current heating stage, the corresponding power-on method of the heating component 100 is determined, and the corresponding two leads are controlled to be energized. This power-on method is different from the power-on method in the initial heating stage.

[0079] In some embodiments, in the subsequent heating step, the multiple heating stages may include an intermediate heating stage.

[0080] Subsequent heating steps may include:

[0081] Mid-term heating: In the mid-term heating stage, two groups of leads are controlled to be energized alternately. One group of leads may include two leads, and the combinations of the two leads in the two groups of leads are different.

[0082] In some embodiments, in the subsequent heating step, the multiple heating stages may include a post-heating stage.

[0083] Subsequent heating steps may include:

[0084] Late heating: In the late heating stage, the first lead 21 and the second lead 22 are controlled to be energized.

[0085] It should be noted that in the embodiment of the present application, the power-on methods of the two heating stages are different, and the leads selected for the two heating stages may be different; in the same stage, multiple groups of leads can be selected to be alternately energized, and the same multiple groups of leads can be selected for the two heating stages, but the order of alternating power-on is different or the heating time of each group is different.

[0086] Through the above heating control method, different power supply methods can be used for heating in different heating stages. The spatial areas and resistances of the heating wires connected to the circuit are different, resulting in different heating effects.

[0087] For ease of description, taking the additional lead 23 as an example, the first lead 21 can be represented by symbol A, the second lead 22 can be represented by symbol B, and the additional lead 23 can be represented by symbol P.

[0088] Taking the heating component 100 shown in FIG3 as an example, for example, in one heating phase, the AP leads are energized. In another heating phase, the AB leads are energized. In this case, the energization methods of the two heating phases can be defined as different. For another example, in one heating phase, the AB and BP leads are alternately energized with a 1:1 alternating energization time ratio; in the other heating phase, the AB and BP leads are alternately energized with a 1:2 alternating energization time ratio. In this case, the energization methods of the two heating phases can be defined as different.

[0089] As shown in FIG8 , the heating component 100 can be provided with multiple additional leads 23 to realize more power supply combinations with the first lead 21 and the second lead 22 , thereby meeting various heating requirements and realizing various heating temperature zones / heating powers.

[0090] This application does not limit the number and connection positions of the additional leads 23. As the number of additional leads 23 increases, more power supply modes can be formed. For example, the heating component 100 provided in this application can have two additional leads 23, one additional lead 23 is arranged near the first end 11 (such as at 1 / 4 of the length of the heating wire 10), and the other is arranged near the midpoint of the length of the heating wire 10 (such as at 1 / 2), which is an implementation method combined with Figures 3 and 4.

[0091] However, due to the volume limitation of the heating element 100, the additional lead 23 is generally connected to the inner coil of the heating wire 10 through the hollow area of ​​the heating wire 10. Therefore, the additional lead 23 needs to be designed with considerations of layout and short-circuit prevention. Therefore, using a single additional lead 23 is the most convenient and safest solution. At the same time, for the sake of simplicity, the following description uses a single additional lead 23 as an example.

[0092] In some embodiments, as shown in FIG. 3 and FIG. 9 (A), there is only one additional lead 23 , and the additional lead 23 is disposed close to the first end portion 11 .

[0093] In the initial heating step, controlling one of the first lead 21 and the second lead 22 and the additional lead 23 to be energized may include:

[0094] The second lead 22 and the additional lead 23 are controlled to be energized.

[0095] In the mid-term heating step, controlling the two sets of leads to be energized alternately may include:

[0096] The first lead 21 and the second lead 22 are determined as one group of leads, and the first lead 21 and the additional lead 23 are determined as another group of leads.

[0097] Control these two sets of leads to be energized alternately.

[0098] In some embodiments, as shown in FIG. 4 and FIG. 9 (B), there is only one additional lead 23 , which is connected to half the length of the heating wire 10 .

[0099] For example, in the mid-heating step, controlling the alternating power supply of two sets of leads may include:

[0100] The second lead 22 and the additional lead 23 are determined as one group of leads, and the first lead 21 and the additional lead 23 are determined as another group of leads.

[0101] Control these two sets of leads to be energized alternately.

[0102] For another example, in the mid-term heating step, controlling the two sets of leads to be energized alternately may include:

[0103] The first lead 21 and the second lead 22 are determined as one group of leads, and the first lead 21 and the additional lead 23 are determined as another group of leads.

[0104] Control these two sets of leads to be energized alternately.

[0105] For ease of description, taking the additional lead 23 as an example, the first lead 21 can be represented by symbol A, the second lead 22 can be represented by symbol B, and the additional lead 23 can be represented by symbol P.

[0106] As shown in FIG3 and FIG9 (A), the additional lead 23 of the heating component 100 can be one, and the additional lead 23 is arranged close to the first end 11, and the length of the heating wire 10 between the corresponding connection point and the first end 11 is 1 / 4 of the first length.

[0107] The heating component 100 can have the following heating modes / operating modes:

[0108] Working Mode I):

[0109] During the initial heating, the P and B leads are energized first (the resistance between BP is greater than the resistance between AP). The heating power density of the upper region of the spiral heating wire 10 (the spiral wire region corresponding to the right dotted box as shown in FIG5 (B)) is about twice that of the lower heating region (the spiral wire region corresponding to the left dotted box as shown in FIG5 (B)). The hot spot temperature is closer to the head of the heating wire 10, which is conducive to concentrating energy consumption to bake the upper aerosol generation matrix and achieve rapid smoke discharge.

[0110] During the later heating, the A and B leads are energized, and the heating power density of the upper region of the spiral heating wire 10 is close to the power density of the lower heating region, which is manifested as the hot spot area migrating away from the head in a directional manner, which is conducive to more complete and balanced baking of the lower aerosol generation matrix that was not fully baked in the early stage.

[0111] It should be noted that the directions of the upper section and the lower end are described based on the up-down directions shown in Figures 8 and 9, corresponding to the left-right directions in Figures 3 and 5. The following working mode directions are the same.

[0112] Working Mode II):

[0113] During the initial heating, the P and B leads are energized first, which is beneficial to concentrate energy consumption to bake the upper aerosol generation matrix and achieve rapid smoke emission.

[0114] Mid-term heating, followed by alternating power supply to the A and B leads and the A and P leads, is beneficial for more fully and evenly baking the lower aerosol-generating matrix that was not fully baked in the early stage.

[0115] During the later heating, the A and B leads are finally energized to bake the aerosol generating matrix as a whole to make it as transparent as possible.

[0116] It should be noted that in this application, for example, during the mid-term heating phase, the switching interval between the two sets of leads alternating between energizing can be approximately 20 milliseconds to 10 seconds, which can be pre-set and preferably 100 milliseconds to 2 seconds; or automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value, and the set target sequence temperature value; or associated with the number of detected puffs, such as the switching time being set as the waiting time between two adjacent puffs; the energizing duration and switching number of leads A and B, and leads A and P, can be pre-set based on puff performance; or automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value, and the set target sequence temperature value; or associated with the number of detected puffs. Subsequent heating phases in other operating modes can be set in the same manner.

[0117] Other working modes III):

[0118] Other permutations and combinations based on the power connection status of the three leads A, B, and P.

[0119] As shown in FIG4 and FIG9(B), the heating component 100 has one additional lead 23, which is disposed in the middle of the heating wire 10. The length of the heating wire 10 between the corresponding connection point and the first end 11 is half of the first length.

[0120] The heating component 100 can have the following heating modes / operating modes:

[0121] Working Mode I):

[0122] For initial heating, energize the P, A lead (or P, B lead) for about 15-30 seconds until the aerosol generating matrix can emit smoke quickly.

[0123] Mid-term heating, followed by alternating powering of the P and B leads, and the P and A leads, is beneficial for achieving a more balanced baking of the aerosol generating matrix.

[0124] The switching time interval of alternating power supply is associated with the number of detected puffs, for example, the switching time is set as the waiting time between two adjacent puffs; it can also be pre-set to approximately 20 milliseconds to 10 seconds, preferably 5-10 seconds; or it can be automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value, and the set target temperature sequence value; the power supply time and switching number of the P, B leads and the P, A leads can be associated with the number of detected puffs; it can also be pre-set according to the inhalation effect; or it can be automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value, and the set target sequence temperature value.

[0125] Working Mode II):

[0126] Based on working mode Ⅰ), post-heating is added.

[0127] During the later heating period, about 1 minute before the end of the puffing, the power-on state changes from P and B leads, and P and A leads alternately energizing to A and B leads energizing.

[0128] Working Mode III):

[0129] For initial heating, energize the P, A lead (or P, B lead) for about 15-30 seconds until the aerosol generating matrix can emit smoke quickly.

[0130] Mid-term heating and then alternately energizing the P and B leads and the A and B leads is beneficial to achieving a more balanced baking of the aerosol generating matrix.

[0131] The switching time interval of alternating power supply is associated with the number of detected puffs. For example, the switching time is set as the waiting time between two adjacent puffs. It can also be pre-set to about 20 milliseconds-10 seconds, preferably 5-10 seconds, or automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value and the set target temperature sequence value. The power supply time and the switching number of the P, B leads and the P, A leads can be associated with the number of detected puffs, or can be pre-set according to the inhalation effect, or automatically determined by the software based on the currently read instantaneous resistance value, the existing TCR value and the set target sequence temperature value.

[0132] Working Mode IV):

[0133] Based on working mode III), post-heating is added.

[0134] During the later heating period, about 1 minute before the end of the puffing, the power-on state changes from P and B leads, A and B leads alternately energized to A and B leads energized.

[0135] Working Mode V):

[0136] Other permutations and combinations based on the power connection status of the three leads A, B, and P.
