[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0051] Please refer to Figure 1 and Figure 2 , Figure 1 is the exploded structural diagram of the heating module 100 provided by the present application; Figure 2 is the cross-sectional structural diagram of the heating module 100 provided by the present application. The heating module 100 provided by the embodiments of the present application can be used in a smoke generating device. A smoke generating device refers to a smoking assistance accessory for a user to smoke tobacco products.

[0052] Among them, the heating module 100 includes an accommodation cavity 40 and a first heating component 30. The accommodation cavity 40 has a first port 40A and a second port 40B which are oppositely arranged. The first port 40A is used for inserting a cigarette into the accommodation cavity 40. The first heating component 30 includes a heat conductor 31 and a heating element 32. The heating element 32 is used to heat the heat conductor 31. One end of the heat conductor 31 is sleeved in the second port 40B and is in contact with the inner side wall 401 of the accommodation cavity 40 to conduct heat to the accommodation cavity 40. At least one air flow channel 310 is provided in the heat conductor 31. The air flow channel 310 communicates with the accommodation cavity 40.

[0053] The heating module 100 provided by the embodiment of the present application adopts a hybrid heating mode of air heating and heat conduction heating. At the beginning of user suction, on the one hand, the heating element 32 is energized to generate heat, and the heat is conducted to the heat conductor 31. Air exchanges heat with the heat conductor 31 through the air flow channel 310 provided in the heat conductor 31 and enters the accommodation cavity 40. The heated air bakes the cigarette rod, causing it to release nicotine and smoke. On the other hand, the first heating component 30 and the accommodation cavity 40 are directly connected in contact, so that the first heating component 30 can effectively conduct heat to the accommodation cavity 40. The accommodation cavity 40 provides auxiliary heating to the periphery of the cigarette rod, making the atomization of the cigarette rod more sufficient, thereby improving the suction experience of the cigarette rod and enhancing the taste.

[0054] It can be understood that the cigarette rod involved in the embodiment of the present application includes tobacco and a smoking substance. The tobacco and the smoking substance are separately arranged. Among them, the tobacco is mainly used to release nicotine, and the smoking substance is mainly used to release smoke and the taste of the cigarette rod required by the user. Among them, the smoking substance is placed on the side of the tobacco away from the first heating component 30. Since the tobacco is closer to the first heating component 30, it will release nicotine before the smoking substance releases smoke, resulting in a poor experience at the beginning of user suction. However, through the hybrid heating mode of air heating and heat conduction heating in the embodiment of the present application, while heating the air, more heat can be provided to the periphery of the cigarette rod, so that the atomization of the cigarette rod is more sufficient, releasing an appropriate amount of nicotine and smoke, thereby improving the suction experience of the cigarette rod.

[0055] Please continue to refer to Figure 1 and Figure 2 In an embodiment of the present application, the heating module 100 includes a bottom bracket 10, a support member 20, a first heating component 30, an accommodation cavity 40, a housing 50, a connecting member 60, and a cover 70.

[0056] Among them, the bottom bracket 10 has a first end 101 and a second end 102 arranged opposite to each other. The support member 20 is arranged at the first end 101. The first heating component 30 is arranged on the side of the support member 20 away from the bottom bracket 10. The accommodation cavity 40 is arranged on the side of the first heating component 30 away from the bottom bracket 10. The housing 50 is arranged on the bottom bracket 10 and covers the support member 20, the heating component 30, and the accommodation cavity 40. The cover 70 is arranged on the side of the housing 50 away from the bottom bracket 10, and the cover 70 is connected to the accommodation cavity 40 through the connecting member 60.

[0057] Specifically, as Figure 2 and Figure 3As shown, the bottom bracket 10 has a receiving cavity 10A. The bottom bracket 10 includes a bracket body 11, a first mounting table 12, and a first mounting ring 13. The bracket body 11, the first mounting table 12, and the first mounting ring 13 are coaxially arranged and connected to each other. The receiving cavity 10A penetrates through the bracket body 11 and the first mounting table 12. The first mounting table 12 is arranged on the bracket body 11. The first mounting ring 13 is arranged on the side of the first mounting table 12 away from the bracket body 11.

[0058] Among them, the first mounting table 12 is cylindrical. A plurality of through holes 12A are provided on the first mounting table 12 for the wiring in the heating module 100 to pass through (such as electrode pins, etc.). A plurality of first fixing parts 131 are provided on the inner side wall of the first mounting ring 13 at intervals. A plurality of second fixing parts 132 are provided on the outer side wall of the first mounting ring 13 at intervals. The settings of the first fixing parts 131 and the second fixing parts 132 realize the point contact connection between the bottom bracket 10 and the first support member 21 and between the bottom bracket 10 and the housing 50, reducing the contact area and thus reducing the heat conduction loss.

[0059] As Figure 2 、 Figure 4 and Figure 5 shown, one end of the first support member 21 facing the bottom bracket 10 is connected to the bottom bracket 10 through the first fixing part 131.

[0060] Specifically, the first support member 21 includes a support body 211, a frustum 212, and a second mounting table 213. The support body 211, the frustum 212, and the second mounting table 213 are coaxially arranged and connected to each other. The frustum 212 is located between the support body 211 and the second mounting table 213. The support body 211 is cylindrical. The outer diameter of the frustum 212 gradually increases towards the second mounting table 213. The inner side wall of the second mounting table 213 is stepped. A third fixing part 2131 is provided on the stepped surface of the second mounting table 213.

[0061] Furthermore, a first through hole 2110 is provided in the support body 211. At least one second through hole 2120 is provided in the frustum 212. The second mounting table 213 is provided with a third through hole 2130. The first through hole 2110, the second through hole 2120, and the third through hole 2130 are communicated with each other. Among them, the aperture of the second through hole 2120 is smaller than the aperture of the first through hole 2110; the aperture of the second through hole 2120 is smaller than the aperture of the third through hole 2130. The aperture of the first through hole 2110 and the aperture of the third through hole 2130 may be the same or different, and the present application does not make specific limitations on this.

[0062] In the embodiment of the present application, the second through hole 2120 is provided to communicate the first through hole 2110 and the third through hole 2130, so as to introduce gas from the self-supporting member 20 into the first heating assembly 30. Since the aperture of the second through hole 2120 is relatively small, on the one hand, the gas can enter the first heating assembly 30 at a stable flow rate, ensuring the uniformity of the temperature at which the gas is heated, thereby improving the user's suction experience; on the other hand, the possibility of the gas flowing back from the first heating assembly 30 to the bottom bracket 10 can be reduced, further reducing heat loss.

[0063] In the embodiment of the present application, the second support member 22 is disposed on the side of the first support member 21 away from the bottom bracket 10. One end of the second support frame 22 facing the first support frame 21 is connected to the first support frame 21 through the third fixing portion 2131. The end of the second support frame 22 away from the first support member 21 is provided with a first annular groove 22A.

[0064] The material of the second support member 22 may include materials with high temperature resistance and low thermal conductivity such as zirconia, silica or ceramics, so as to prevent the heat of the first heating assembly 30 from being conducted downward, while avoiding heat loss, ensuring that the first heating assembly 30 conducts more residual heat to the accommodation cavity 40.

[0065] In the embodiment of the present application, the first heating assembly 30 is disposed on the side of the second support member 22 away from the bottom bracket 10. The accommodation cavity 40 is disposed on the side of the first heating assembly 30 away from the bottom bracket 10.

[0066] Among them, the accommodation cavity 40 has a first port 40A and a second port 40B disposed opposite to each other. The first port 40A is used for inserting a cigarette stick into the accommodation cavity 40.

[0067] Among them, the first heating assembly 30 includes a heat conductor 31 and a heating element 32. The heating element 32 is used to heat the heat conductor 21. At least one air flow channel 310 is provided in the heat conductor 21. The air flow channel 310 communicates with the accommodation cavity 40. One end of the heat conductor 31 close to the second support member 22 is disposed in the first annular groove 22A. The end of the heat conductor 31 away from the second support member 22 is sleeved in the second port 40B and is attached to the inner side wall 401 of the accommodation cavity 40 to conduct heat to the accommodation cavity 40.

[0068] Specifically, as Figure 2 and Figure 6As shown in the figure, the first heating component 30 includes a heat conductor 31 and a heating element 32. The heat conductor 31 includes a heat-conducting main body 311. On one side of the heat-conducting main body 311 close to the accommodating cavity 40, there is an annular flange 312. On one side of the flange 312 close to the accommodating cavity 40, there is a first annular wall 313. The first annular wall 313 is sleeved inside the second port 40B. The inner side wall 401 of the accommodating cavity 40 is attached to the outer side wall of the first annular wall 313. The end face of the accommodating cavity 40 close to the heat-conducting main body 311 abuts against the side of the flange 312 away from the heat-conducting main body 311.

[0069] In the embodiment of the present application, since the inner side wall 401 of the accommodating cavity 40 is attached to the outer side wall of the first annular wall 313, and the end face of the accommodating cavity 40 close to the heat-conducting main body 311 abuts against the side of the flange 312 away from the heat-conducting main body 311, the contact area between the accommodating cavity 40 and the heat conductor 31 is increased, enabling the heat conductor 31 to conduct more heat to the accommodating cavity 40. The heated accommodating cavity 40 provides auxiliary heating to the periphery of the cigarette, making the atomization of the cigarette more sufficient, thereby improving the smoking experience of the cigarette and enhancing the taste.

[0070] In the embodiment of the present application, at least one air flow channel 310 is provided in the heat conductor 31. The air flow channel 310 penetrates through the heat-conducting main body 311 and the flange 312. Specifically, the number of air flow channels 310 can be 1, 2, 3, 4, 5, 6 or more, and the present application does not make specific limitations thereto. Further, multiple air flow channels 310 are uniformly arranged in the heat-conducting main body 311, and the shape and size of each air flow channel 310 are the same, so that the air flowing through each air flow channel 310 can be uniformly heated.

[0071] In the embodiment of the present application, the length of the first annular wall 313 extending towards the accommodating cavity 40 is 1 mm to 2 mm. When the size of the heating module 100 is fixed, this setting enables the accommodating cavity 40 to have enough space for the cigarette to be inserted therein. Specifically, in some embodiments, the length of the first annular wall 313 extending towards the accommodating cavity 40 is 1 mm, 1.2 mm, 1.5 mm, 1.8 mm or 2 mm, and the present application does not make specific limitations thereto.

[0072] In the embodiment of the present application, the end face of the first annular wall 313 away from the heat-conducting main body 311 is used to abut against the end face of the cigarette close to the heat-conducting main body 311. Among them, the wall thickness of the first annular wall 313 is 0.15 mm to 0.25 mm. For example, the wall thickness of the first annular wall 313 is 0.15 mm, 0.18 mm, 0.2 mm, 0.22 mm or 0.25 mm, and the present application does not make specific limitations thereto.

[0073] It can be understood that the general working principle of current smoking devices is to directly heat the cigarette with a heating component to generate smoke. However, in this heating method, due to the direct contact between the heating component and the cigarette, on the one hand, the contact between the heating component and the cigarette at high temperature will produce an odor, and on the other hand, the heating component will have the problem of uneven heating due to the blockage of the cigarette. The above two reasons will lead to problems such as poor taste and impure aroma of the cigarette.

[0074] In the embodiment of the present application, the end face of the first annular wall 313 away from the heat conduction main body 311 abuts against the end face of the cigarette close to the heat conduction main body 311, which can effectively reduce the contact area between the cigarette and the heat conduction main body 311. In addition, the atomization temperature of the cigarette is generally 200 degrees, and the temperature of the heat conductor 31 is generally lower than 280 degrees. Therefore, in the embodiment of the present application, while achieving a high heat conduction rate between the heat conduction main body 311 and the accommodation cavity 40, the problems of poor taste and impure aroma of the cigarette can be avoided.

[0075] Further, in the embodiment of the present application, the heating element 32 is arranged on the outer side wall of the heat conduction main body 311 to heat the heat conduction main body 311.

[0076] Specifically, in one embodiment, the heating element 32 includes a heating wire 321 and two pins 322. One of the pins 322 is connected to one end of the heating wire 321. The other pin 322 is connected to the other end of the heating wire 321. A groove 311A is provided on the heat conduction main body 311. The heating wire is arranged in the groove 311A.

[0077] By providing the groove 311A on the outer side wall of the heat conduction main body 311 and arranging the heating wire 321 in the groove 311A, on the one hand, it plays a role in limiting the heating wire 321 to prevent the heating wire 321 from moving during the installation process; on the other hand, the shape of the groove 311A matches and fits with the shape of the heating wire 321 to increase the contact area between the heating wire 321 and the heat conduction main body 311, thereby improving the heating efficiency of the heat conduction main body 311; furthermore, during the assembly process of the first heating component 30, the groove 311A plays a guiding role, that is, the wire of the heating wire 321 can be wound along the groove 311A and in the groove 311A by using an automatic winding machine, which is simple and fast, improving the manufacturing process efficiency; at the same time, it avoids short circuits between the windings of the heating wire 321.

[0078] Further, the groove 311A is uniformly arranged in a spiral shape on the outer side wall of the heat conductor 311, and the heating wire 321 is wound around the heat conduction main body 311 in a spiral shape, improving the uniformity of the heating of the first heating component 30. Of course, the heating wire 321 can also be wound around the heat conduction main body 311 non-uniformly.

[0079] In addition, the heat conductor 31 and the accommodating cavity 40 are made of materials with a high thermal conductivity coefficient to improve the heat conduction efficiency between the heat conductor 31 and the accommodating cavity 40. Specifically, the materials of the heat conductor 31 and the accommodating cavity 40 may include sintered bodies of materials such as alumina, zirconia, or silicon nitride; or may include metal materials such as aluminum, copper, or iron. Among them, when a metal material is selected to prepare the heat conductor 31, the surface of the heat conductor 31 needs to be insulated to prevent a short - circuit problem of the heating element 32 when the heat conductor 31 contacts the heating element 32.

[0080] Please continue to refer to Figure 1 、 Figure 2 and Figure 3 , the housing 50 is fixed to the bottom bracket 10 through the second fixing portion 132 and covers the support member 20, the first heating assembly 30, and the accommodating cavity 40. A cavity 50A is formed between the support member 20, the first heating assembly 30, the accommodating cavity 40, and the housing 50.

[0081] Among them, the housing 50 is made of a material with a low thermal conductivity coefficient. For example, stainless steel can be used to reduce the probability of heat conduction in the radial direction in the cavity 50A. The cavity 50A can be filled with heat - insulating materials to reduce heat dissipation. Specifically, at least one heat - insulating layer (not marked in the figure) can be provided on the inner side wall of the housing 50 or the outer side wall 402 of the accommodating cavity 40. The heat - insulating layer can be a heat - insulating film layer formed by porous materials such as fiberglass, aerogel, or heat - insulating cotton, or can be a heat - reflecting film layer formed by metal materials with heat - reflecting properties such as aluminum, gold, silver, or nickel. Or, it can also be a film material such as a polyester or polyimide film coated with a metal material that can reflect radiant heat energy. The present application does not specifically limit the structure and materials of the heat - insulating layer.

[0082] Specifically, fiberglass can be selected as the heat - insulating material. Wrapping and filling fiberglass in the cavity 50A can, on the one hand, wrap the heat released by the first heating assembly 30 and improve the working efficiency of the first heating assembly 30; on the other hand, it can effectively prevent heat from diffusing and losing to the housing 50 in the form of radiation, effectively reducing heat loss and lowering the temperature of the housing 50.

[0083] In the embodiment of the present application, the connecting member 60 is arranged on the side of the accommodating cavity 40 away from the first heating assembly 30. One end of the connecting member 60 facing the accommodating cavity 40 is provided with a second annular groove 60A. The first port 40A of the accommodating cavity 40 is inserted into the second annular groove 60A.

[0084] In the embodiment of the present application, the cover body 70 is arranged on the side of the connecting body 60 away from the accommodating cavity 40. A plurality of limiting blocks 701 are provided at one end of the cover body 70 facing the connecting body 60. The connecting body 60 is connected to the inner peripheral edge defined by the limiting blocks 701. The accommodating cavity 40 is connected to the outer peripheral edge defined by the limiting blocks 701.

[0085] Wherein, both the connecting member 60 and the cover body 70 are hollow structures with upper and lower openings, so that a cigarette can be inserted into the accommodating cavity 40.

[0086] Please refer to Figure 7 and Figure 8 , Figure 7 is a schematic cross-sectional structure diagram of another heating module 100 provided by the present application. Figure 8 is Figure 7 an enlarged schematic cross-sectional structure diagram of the first heating component 30 in Figure 2 Shown heating module 100. Different from the heating module 100 shown in Figure 2 , in the first heating component 30 of the embodiment of the present application, a second annular wall 314 is further provided on the side of the flange 312 close to the accommodating cavity 40. The second annular wall 314 is arranged around the first annular wall 313, and a gap 31A is formed between the first annular wall 313 and the second annular wall 314. The accommodating cavity 40 is sleeved in the gap 31A.

[0087] Wherein, the outer side wall of the first annular wall 313 is attached to the inner side wall 401 of the accommodating cavity 40. The inner side wall of the second annular wall 314 is attached to the outer side wall 402 of the accommodating cavity.

[0088] Wherein, the length of the second annular wall 314 extending towards the accommodating cavity 40 is greater than or equal to the length of the first annular wall 313 extending towards the accommodating cavity 40. In one embodiment, the length of the second annular wall 314 extending towards the accommodating cavity 40 is equal to the length of the first annular wall 313 extending towards the accommodating cavity 40. The length of the second annular wall 314 extending towards the accommodating cavity 40 is 1 millimeter to 2 millimeters. For example, the lengths of the first annular wall 313 and the second annular wall 314 extending towards the accommodating cavity 40 are both 1 millimeter, 1.2 millimeters, 1.5 millimeters, 1.8 millimeters or 2 millimeters, and the present application does not make specific limitations on this.

[0089] In the embodiment of the present application, by providing the first annular wall 313 and the second annular wall 314, and attaching the accommodating cavity 40 to the first annular wall 313 and the second annular wall 314 respectively, the contact area between the accommodating cavity 40 and the heat conducting body 31 is further increased, so that the heat conducting body 31 can conduct more heat to the accommodating cavity 40. The heated accommodating cavity 40 provides auxiliary heating to the periphery of the cigarette, making the atomization of the cigarette more sufficient, thereby improving the smoking experience of the cigarette and enhancing the taste.

[0090] Please refer to Figure 9 andFigure 10 , Figure 9 is an exploded structural view of another heating module 100 provided by the present application, Figure 10 and is Figure 9 a structural view of the second heating component 80 in Figure 1 . The difference from the heating module 100 shown in

[0091] is that the heating module 100 provided by the embodiments of the present application further includes a second heating component 80 and a temperature sensor 90.

[0092] Specifically, please refer to Figure 11 . The second heating component 80 includes a heating mesh 81 and electrode pins 82. The heating mesh 81 is sleeved on the outer side wall 402 of the accommodation cavity 40. The electrode pins 82 are bonded to the outer side wall 402 of the accommodation cavity 40 through a heat-conducting colloid 83.

[0093] Among them, there are two electrode pins 82. One electrode pin 82 is connected to one end of the heating mesh 81, and the other electrode pin 82 is connected to the other end of the heating mesh 81. The two electrode pins 82 are attached to the accommodation cavity 40 and are arranged oppositely. In the radial direction of the accommodation cavity 40, the thickness of the electrode pins 82 is greater than the thickness of the heating mesh 81. Among them, the two electrode pins 82 and the outer side wall 402 of the accommodation cavity 40 define a groove 80A. The heat-conducting colloid 83 is arranged in the groove 80A. The heat-conducting colloid 83 is used to bond the electrode pins 82 and the accommodation cavity 40. The temperature sensor 90 is arranged in the groove 80A and is bonded to the outer side wall 402 of the accommodation cavity 40 through the heat-conducting colloid 83.

[0094] In the embodiments of the present application, the heating module 100 has a preheating stage and a heating stage. Among them, the preheating stage specifically refers to: before the user smokes a cigarette, preheating the cigarette so that the cigarette fully atomizes to release nicotine and smoke, thereby improving the user's experience at the beginning of smoking. The heating stage specifically refers to: during the user's smoking process, heating the cigarette so that the cigarette continuously releases nicotine and smoke.

[0095] Specifically, in an embodiment of the present application, when the heating module 100 is in the preheating stage or the heating stage, both the first heating component 30 and the second heating component 80 are in a working state.

[0096] Further, when the heating module 100 is in the preheating stage, the second heating component 80 has a first heating power; when the heating module 100 is in the heating stage, the second heating component 80 has a second heating power. Among them, the first heating power is greater than the second heating power.

[0097] It can be understood that the purpose of the preheating stage is to preheat the bottom and the periphery of the cigarette. When the user starts to smoke the cigarette, the cigarette can fully release nicotine and smoke, improving the taste of cigarette smoking. And as can be seen from the foregoing embodiments, in the prior art, at the beginning of suction, the release speed of the smoke is less than the release speed of nicotine. Therefore, in the embodiment of the present application, the first heating power is set to be greater than the second heating power, so that the second heating component 80 provides more heat to the accommodation cavity 40 during the preheating stage, thereby fully heating the periphery of the cigarette, making the atomization of the cigarette more sufficient, improving the taste of the initial suction, and shortening the preheating time at the same time. During the heating stage, the first heating component 30 continuously heats the gas, and the heated gas continuously bakes the bottom of the cigarette. At this time, since the first heating component 30 outputs heat to the accommodation cavity 40 through heat conduction, setting a smaller second heating power can ensure the temperature of the accommodation cavity 40 is constant to bake the periphery of the cigarette, thereby reducing the power consumption of the second heating component 80.

[0098] Optionally, when the heating module 100 is in the preheating stage, the ratio of the heating powers of the first heating component 30 and the second heating component 80 is 7:3; when the heating module 100 is in the heating stage, the ratio of the heating powers of the first heating component 30 and the second heating component 80 is 8:2.

[0099] Specifically, during the preheating stage, the first heating component 30 is used to heat the gas entering the air flow channel 310, and the heated air bakes the bottom of the cigarette; at the same time, the second heating component 80 heats the accommodation cavity 40 to bake the periphery of the cigarette. The first heating component 30 and the second heating component 80 work simultaneously, effectively shortening the preheating time. At the same time, setting a larger second heating power can fully bake the periphery of the cigarette, achieve sufficient atomization, and improve the taste of the initial suction.

[0100] During the heating stage, the cigarette has been able to be normally atomized and emit smoke after preheating. At this time, increasing the ratio of the heating powers of the first heating component 30 and the second heating component 80 enables more waste heat of the first heating component 30 to be conducted to the accommodation cavity 40. The combined action of this waste heat and the heat generated by the second heating component 80 on the accommodation cavity 40 can ensure the temperature of the accommodation cavity 40 is constant, thereby reducing the power consumption of the second heating component 80.

[0101] In another embodiment of the present application, when the heating module 100 is in the preheating stage, both the first heating component 30 and the second heating component 80 are in the working state; when the heating module 100 is in the heating stage, the first heating component 30 is in the working state, and the second heating component 80 is in the off state.

[0102] Similarly, in the preheating stage, the first heating component 30 is used to heat the gas entering the air flow channel 310, and the heated air further bakes the bottom of the cigarette rod; at the same time, the second heating component 80 heats the accommodation cavity 40 to bake the periphery of the cigarette rod. The first heating component 30 and the second heating component 80 work simultaneously, effectively shortening the preheating time. And in order to fully atomize the cigarette rod, the heating power of the second heating component 80 can be adjusted according to the actual temperature of the accommodation cavity 40, so that the periphery of the cigarette rod is fully baked, thereby achieving full atomization and improving the initial suction taste.

[0103] In the heating stage, since the present application provides that the heat conductor 31 and the accommodation cavity 40 are directly in contact and connected, the heat conductor 31 can effectively conduct heat to the accommodation cavity 40. Therefore, the second heating component 80 can be turned off in the heating stage. At this time, on the one hand, the first heating component 30 is used to heat the gas, and the heated gas bakes the bottom of the cigarette rod; on the other hand, the heat conducted from the first heating component 30 to the accommodation cavity 40 ensures that the temperature of the accommodation cavity 40 is constant, and then bakes the periphery of the cigarette rod.

[0104] It can be understood that in the heating stage, that is, when the user sucks, directly heating the accommodation cavity 40 by the second heating component 80 is likely to cause the temperature of the accommodation cavity 40 to be too high, there is a possibility of scalding the user's oral cavity, and it will cause an alarm of the temperature sensor 90, further increasing the power loss of the heating module 100. In the embodiment of the present application, the second heating component 80 is turned off in the heating stage, effectively reducing the power loss of the heating module 100. At the same time, since the first heating component 30 and the accommodation cavity 40 are directly in contact and connected, the accommodation cavity 40 can obtain enough heat to maintain its temperature in the heating stage. Therefore, turning off the second heating component 80 will not affect the user's suction experience.

[0105] In another embodiment of the present application, the heating module 100 has multiple heating modes. In each heating mode, the first heating component 30 and the second heating component 80 have corresponding heating power ratios.

[0106] Specifically, for example, the heating module 100 has a first heating mode, a second heating mode, and a third heating mode. When the heating module 100 is in the first heating mode, the heating power ratio of the first heating component 10 and the second heating component 80 is 8:2; when the heating module 100 is in the second heating mode, the heating power ratio of the first heating component 10 and the second heating component 80 is 7:3; when the heating module 100 is in the third heating mode, the heating power ratio of the first heating component 10 and the second heating component 80 is 5:5.

[0107] It can be understood that from common knowledge and experiments, the higher the heating power of the first heating component 30, the higher the baking temperature at the bottom of the tobacco, and the greater the nicotine release; the greater the heating power of the second heating component 80, the more sufficient the heating of the cigarette periphery, and the greater the smoke release.

[0108] Some users have a strong taste and need to inhale a large amount of nicotine, while some users only need a small amount of nicotine inhalation; or, for the same user, in different environments or mood states, different nicotine or smoke inhalation amounts are also required. Therefore, the heating module 100 provided in the embodiments of the present application can provide different heating modes. In different heating modes, the heating power ratio of the first heating component 30 and the second heating component 80 is set to release different proportions of heat, and then different proportions of nicotine and smoke amounts are released to meet the different needs of users.

[0109] It should be noted that the heating module 100 provided in the embodiments of the present application can set the heating power of the first heating component 30 and the second heating component 50 according to the actual needs of the user, so as to set different types of heating modes. That is, the heating mode is not limited to the above three types. The above embodiments only illustrate the technical solution and should not be construed as a limitation of the present application.

[0110] The present application also provides a heating module 100. Please continue to refer to Figure 9 . The heating module 100 includes a receiving cavity 40, a first heating component 30, and a second heating component 80. The receiving cavity 40 has a first port 40A and a second port 40B that are oppositely arranged. The first port 40A is used for inserting a cigarette into the receiving cavity 40. The first heating component 30 includes a heat conductor 31 and a heating element 32. The heating element 32 is used to heat the heat conductor 31. One end of the heat conductor 31 is sleeved in the second port 40B and is attached to the inner side wall 401 of the receiving cavity 40 to conduct heat to the receiving cavity 40. At least one air flow channel 310 is provided in the heat conductor 31. The air flow channel 310 communicates with the receiving cavity 40. The second heating component 80 is disposed on the outer side wall 402 of the receiving cavity 40. The second heating component 80 is used to heat the receiving cavity 40. Among them, the first heating component 30 and the second heating component 80 are connected in parallel.

[0111] The heating module 100 provided in the embodiment of the present application can reduce the preheating time by setting the first heating component 30 and the second heating component 80 on the one hand; on the other hand, it can make the cigarette more fully atomized and improve the user's smoking experience. In addition, the first heating component 30 and the second heating component 80 are arranged in parallel, and the first heating component 30 and the second heating component 80 can work synchronously. That is, by inputting the same driving voltage, the first heating component 30 and the second heating component 80 can be turned on at the same time, which simplifies the driving process of the heating module 100 and simplifies the circuit structure in the heating module 100.

[0112] It should be noted that the various components in the heating module 100 provided in the embodiment of the present application can refer to the above embodiment and will not be described in detail here.

[0113] Furthermore, the heating module 100 has a plurality of heating modes. In each heating mode, the first heating element 30 and the second heating element 80 have a corresponding resistance value ratio.

[0114] Similarly, some users have strong tastes and need to inhale a large amount of nicotine, while some users only need to inhale a small amount of nicotine; or the same user, in different environments or moods, also needs to satisfy different nicotine or smoke inhalation amounts. Therefore, the heating module 100 provided in the embodiment of the present application can provide different heating modes.

[0115] It is understandable that for two parallel branches, when the same driving voltage is input, the greater the resistance value of the branch, the smaller the heating power. Therefore, when the first heating component 30 and the second heating component 80 are connected in parallel, the resistance value of the first heating component 30 and the resistance value of the second heating component 80 are designed according to different heating modes, and the heating power ratio of the first heating component 30 and the second heating component 80 can be changed, so that the heating module 100 releases different proportions of nicotine and smoke in different heating modes to meet the needs of different users for the taste of the smoke.

[0116] Specifically, the first heating component 30 includes a heating element 32, and the heating element 32 includes a heating wire 321 and a pin 322. The second heating component 80 includes a heating net 81 and an electrode pin 82. The heating element 32 and the heating net 81 are connected in parallel through the pin 321 and the electrode pin 82.

[0117] Further, the resistance value of the heating element 32 can be set to be less than or equal to the resistance value of the second heating component 80, so that the resistance value of the first heating component 30 is less than or equal to the resistance value of the second heating component 80. In other embodiments, the resistance value of the first heating component 30 and / or the second heating component 80 can also be changed by changing the material thereof, which is not specifically limited in the present application.

[0118] The embodiment of the present application sets the first heating component 30 and the second heating component 80 in parallel, and then controls the heating power ratio of the first heating component 30 and the second heating component 80 by setting the resistance ratio of the first heating component 30 and the second heating component 80. The structure is simple and a variety of heating modes of the heating module 100 can be realized, thereby meeting different needs of users.

The smoking device 1000 is a smoking auxiliary accessory, which is used for a user to smoke a smoking product. Specifically, the smoking product can be tobacco or a cigarette.

[0121] The power module 300 is electrically connected to the driving module 200. The driving module 200 is electrically connected to the heating module 100. The power module 300 is used to supply power to the driving module 200 and the heating module 100. The temperature control module 400 is used to monitor the temperature of the heating module 100. The driving module 200 drives the heating module 100 to work, and enables the heating module 100 to heat the air entering the heating module 100, and the hot air bakes the tobacco products, and at the same time, the heating module 100 is in contact with the accommodating cavity, and the heat is transferred to the accommodating cavity, and the periphery of the tobacco products is heated, so that the tobacco products are fully atomized into smoke for the user to smoke, thereby improving the user's smoking experience.
