[0007] A cover is disposed at the opening end of the heating channel, and the cover forms a through-type cigarette channel. The cigarette channel is connected to the heating channel so that the cigarette can enter and exit the heating channel through the cigarette channel. The inner wall of the cigarette channel has spaced protrusions so that when the cigarette is inserted into the cigarette channel, the cigarette and the inner wall of the cigarette channel are at least partially spaced apart. The cigarette channel is connected to the air intake channel.

[0008] In some embodiments, a plurality of the spacer protrusions are provided at intervals along the periphery of the cigarette channel; and / or,

[0009] The height of the interval protrusion is greater than 1 mm.

[0010] In some embodiments, the diameter of the cigarette channel is larger than the diameter of the heating channel.

[0011] In some embodiments, the smoking device body includes:

[0012] A housing having a mounting cavity;

[0013] A heating module is installed in the mounting cavity and spaced apart from the outer casing. The air intake channel is at least partially located in the gap between the heating module and the outer casing, and the heating channel is formed in the heating module.

[0014] In some embodiments, the smoking device body further includes an airway assembly, the airway assembly comprising:

[0015] The first air passage structure is sleeved on the outside of the heating module;

[0016] An airway tube is sleeved on the outside of the first airway structure and is at least partially spaced from the first airway structure. The gap between the airway tube and the first airway structure constitutes at least part of the air intake channel.

[0017] In some embodiments, the first airway structure includes:

[0018] A sealing tube is disposed inside the air passage tube and is at least partially spaced from the tube wall of the air passage tube. The sealing tube is sleeved on the outside of the heating module.

[0019] A first mounting bracket is provided, which is centrally through-hole to connect the heating channel and the cigarette channel. An annular rib is provided on the outer side of the first mounting bracket, and the annular rib is abutted against the top end of the sealing tube. An air inlet is provided at the top end of the first mounting bracket, and an air passage groove is provided at the annular rib to guide the airflow from the cigarette channel to the air inlet channel through the air inlet and the air passage groove.

[0020] In some embodiments, the portion of the first mounting bracket located within the sealing tube is provided with a mounting groove, and the first air passage structure further includes a sealing ring disposed within the mounting groove; and / or

[0021] The outer circumference of the sealing tube is provided with air passage ribs, and the air passage ribs are provided with multiple air vent grooves; and / or

[0022] The first mounting bracket has an annular baffle at its through-hole portion, and the annular baffle is positioned above the heating module.

[0027] In the embodiments of this application, by providing the spacer protrusion on the inner wall of the cigarette channel, when the cigarette is inserted into the cigarette channel, the cigarette and the inner wall of the cigarette channel are at least partially spaced apart, thereby allowing gas to enter the cigarette channel. On the one hand, this can cool the smoke inside the cigarette, preventing the hot smoke from burning the user's mouth. On the other hand, since the cigarette channel is connected to the air intake channel and the air intake channel is connected to the heating channel, the gas inside the cigarette channel can enter the heating channel from the air intake channel and interact with the cigarette to form smoke. For electronic cigarettes, there is no need to provide an additional air intake hole, allowing the cigarette channel to simultaneously perform the functions of air intake and exhaust, thus improving the aesthetic appearance of the electronic cigarette. Furthermore, the air intake of the cigarette channel can be heated by the high-temperature smoke inside the cigarette. In addition, the air intake channel is at least partially located on the outer periphery of the heating channel. Therefore, when the gas moves to the air intake channel, it can also be preheated by the heat dissipated by the heating channel, thereby using the heat that would otherwise be lost to preheat the air intake and improving the energy efficiency of the electronic cigarette device.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0051] Heated tobacco products (HTPs) are electronic devices that heat cigarettes at low temperatures without burning them. Compared to traditional e-liquid or cartridge-based HTPs, their inhalation taste is closer to that of traditional cigarettes, and they release fewer harmful substances than traditional cigarettes.

[0052] Currently, the cigarette channel of heated non-combustible electronic cigarettes is generally designed to be through-hole, with one end for inserting the cigarette and the other end forming an air inlet. The air inlet is exposed on the product casing, affecting the product's appearance, and also resulting in significant heat loss and high energy efficiency.

[0053] For this, please refer to Figures 1 to 4 This application provides an electronic cigarette device 100, which includes a main body and a cover 10. The main body has a heating channel 21 with one open end for inserting a cigarette. An air intake channel 44 is also formed inside the main body, communicating with the heating channel 21 and located at least partially on the outer periphery of the heating channel 21. The cover 10 is disposed at the open end of the heating channel 21 and has a through-type cigarette channel 11 communicating with the heating channel 21, allowing the cigarette to enter and exit the heating channel 21 through the cigarette channel 11. The inner wall of the cigarette channel 11 has spaced protrusions 12, so that when the cigarette is inserted into the cigarette channel 11, the cigarette and the inner wall of the cigarette channel 11 are at least partially spaced apart, and the cigarette channel 11 communicates with the air intake channel 44.

[0054] Please refer to the following: Figure 5 and Figure 6 It should be emphasized that the form of the cover 10 is not limited. It can be integrally formed with the main body of the smoking device, or it can be detachably formed with the main body of the smoking device. It can be installed on the top of the main body of the smoking device, or it can be installed on the bottom or side of the main body of the smoking device, etc., and is not limited here. In some embodiments, the cover 10 is the top cover of the electronic cigarette device 100. The spacer protrusion 12 can be provided as one or more, etc., and is not limited here.

[0055] The air intake channel 44 is at least partially located on the outer periphery of the heating channel 21. It may be only partially located on the outer periphery of the heating channel 21, or it may be entirely located on the outer periphery of the heating channel 21, etc., which are not limited here.

[0056] It should be noted that for traditional electronic cigarette devices, the heating module inevitably dissipates some heat outwards. This heat can cause the surface temperature of the product to rise to an uncomfortable high temperature, resulting in burns. However, in this application, since the air intake channel 44 is located on the outer periphery of at least part of the heating channel 21, the heat dissipated by the heating module 20 can be used to preheat the air intake. This improves the energy efficiency of the electronic cigarette device 100 and also prevents the outer surface temperature of the product from becoming too high, thus avoiding burns.

[0057] Currently, the smoke generated within the heating channel 21 of a cigarette is generally at a high temperature. If this smoke is directly inhaled by the user, it will burn their mouth. Therefore, a cooling section is usually set up inside the cigarette. However, since the size of the cigarette is fixed, the design of the cooling section occupies a lot of space, resulting in less smoke-generating material in the cigarette, a shorter smoking time, and a poor user experience. In this application, by enabling the cigarette channel 11 to function as an air intake, the air intake in the cigarette channel 11 can also cool the smoke in the cigarette, thereby appropriately reducing the size of the cooling section, allowing more smoke-generating material to be placed in the cigarette, thus extending the smoking time and improving the user experience.

[0058] In the embodiments of this application, by providing the spacer protrusion 12 on the inner wall of the cigarette channel 11, when the cigarette is inserted into the cigarette channel 11, the cigarette and the inner wall of the cigarette channel 11 are at least partially spaced apart, thereby allowing gas to enter the cigarette channel 11. On the one hand, this can cool the smoke inside the cigarette, preventing the hot smoke from burning the user's mouth. On the other hand, since the cigarette channel 11 is connected to the air intake channel 44, and the air intake channel 44 is connected to the heating channel 21, the gas inside the cigarette channel 11 can enter the heating channel 21 from the air intake channel 44 and interact with the cigarette to form smoke. For the electronic cigarette device 100, there is no need to provide an additional air intake hole 61, allowing the cigarette channel 11 to simultaneously perform the functions of air intake and exhaust, thus improving the aesthetic appearance of the electronic cigarette device 100. Furthermore, the air intake of the cigarette channel 11 can be heated by the high-temperature smoke inside the cigarette. In addition, the air intake channel 44 is at least partially located on the outer periphery of the heating channel 21. Therefore, when the gas moves to the air intake channel 44, it can also be preheated by the heat dissipated from the heating channel 21, thereby using the heat that would otherwise be lost to preheat the air intake and improving the energy efficiency of the electronic cigarette device 100.

[0059] The fit between the spacer protrusion 12 and the cigarette is not limited; it can be an interference fit, a butt fit, etc., and is not limited here. The installation method between the cover 10 and the body of the smoking device is not limited; it can be a snap-fit, an adhesive fit, etc. In some embodiments, the cover 10 and the body of the smoking device are connected by threads, which provides the best airtightness of the connection.

[0060] In some embodiments, when the cigarette is inserted into the cigarette channel 11, the cigarette and the spacer protrusion 12 are in an interference fit. This arrangement allows the spacer protrusion 12 to better fix the cigarette.

[0061] In a further embodiment, the inscribed circle diameter of the spacer protrusion 12 is 0.5 mm smaller than the diameter of the cigarette, thereby preventing the spacer protrusion 12 from causing too much deformation to the cigarette and maintaining the smooth flow of smoke.

[0062] In some embodiments, multiple spacer protrusions 12 are spaced apart along the periphery of the cigarette channel 11. This arrangement provides better fixation of the cigarette by the multiple spacer protrusions 12, allowing the cigarette to be positioned in the middle of the cigarette channel 11, while also enabling gas to smoothly enter the cigarette channel 11 through the gaps between the multiple spacer protrusions 12, thus improving the smoothness of air intake.

[0063] Specifically, the number of the spacer protrusions 12 is not limited; it can be two, three, four, etc., and is not limited here. Please refer to the relevant documentation. Figure 5 and Figure 6 In some embodiments, four spacer protrusions 12 are provided.

[0064] The height of the interval protrusion 12 is not limited and can be any value according to actual needs. In some embodiments, the height of the interval protrusion 12 is greater than 1 mm.

[0065] Understandably, if the height of the interval protrusion 12 is too small, when the cigarette is inserted into the cigarette channel 11, on the one hand, it may cause most of the cigarette to be in contact with the inner wall of the cigarette channel 11, resulting in poor air intake; on the other hand, it may cause the gap between the cigarette and the inner wall of the cigarette channel 11 to be too small, resulting in insufficient air intake.

[0066] In the scheme of this embodiment, by making the height of the interval protrusion 12 greater than 1mm, when the cigarette is inserted into the cigarette channel 11, a sufficiently large gap is maintained between the cigarette and the inner wall of the cigarette channel 11, thus ensuring the air intake.

[0067] The diameters of the heating channel 21 and the cigarette channel 11 can be the same or different, and no limitation is made here.

[0068] In some embodiments, the diameter of the cigarette channel 11 is larger than the diameter of the heating channel 21.

[0069] It should be noted that if the diameters of the cigarette channel 11 and the heating channel 21 are the same, or if the diameter of the heating channel 21 is larger than the diameter of the cigarette channel 11, a certain gap will inevitably be formed between the heating channel 21 and the cigarette when the cigarette is inserted into the heating channel 21, affecting the heating effect.

[0070] In this embodiment, by setting the diameter of the heating channel 21 to be smaller than the diameter of the cigarette channel 11, the gap between the cigarette and the heating channel 21 can be reduced or eliminated, thereby improving the heating efficiency of the cigarette. Furthermore, the heating channel 21 can also, to some extent, limit the movement of the cigarette.

[0071] The specific implementation of the main body of the smoking device is not limited and can be any form according to actual needs. In some embodiments, the main body of the smoking device includes a shell 30 and a heating module 20. The shell 30 forms an installation cavity. The heating module 20 is installed in the installation cavity and is spaced apart from the shell 30. The air intake channel 44 is at least partially located in the gap between the heating module 20 and the shell 30, and the heating channel 21 is formed in the heating module 20.

[0072] In the scheme of this embodiment, the heating module 20 generates heat and radiates it in all directions. When the heat is radiated to the heating channel 21, it can heat the cigarette in the heating channel 21. When the heat is radiated to the air intake channel 44, it can preheat the air, thereby improving the heating efficiency of the electronic cigarette device 100.

[0073] Specifically, the specific implementation of the heating module 20 is not limited. It can be a heating method using electric heating wire, or a heating method using carbon fiber, etc., and is not limited here.

[0074] In some embodiments, the heating module 20 includes a heating element that heats the cigarette by converting electrical energy into heat energy in the form of thermal radiation.

[0075] In some embodiments, the main body of the smoking device further includes an air passage assembly 40, the air passage assembly 40 including a first air passage structure and an air passage tube 41, the first air passage structure being sleeved on the outside of the heating module 20; the air passage tube 41 being sleeved on the outside of the first air passage structure and at least partially spaced from the first air passage structure, the gap between the air passage tube 41 and the first air passage structure at least forming a portion of the air intake channel 44.

[0076] It should be noted that the first air passage structure is sleeved on the outside of the heating module 20, thereby providing a certain degree of heat insulation and sealing for the heating module 20, preventing the high-temperature flue gas in the heating channel 21 from diffusing into the air intake channel 44, and also providing a certain degree of obstruction to the diffusion of heat generated by the heating module 20 to the outside of the heating channel 21.

[0077] By providing the airway tube 41, which is sleeved on the outside of the first airway structure and at least partially spaced from it, when gas enters the electronic cigarette device 100, it can be constrained between the airway tube 41 and the first airway structure, preventing the air from spreading everywhere and improving the smoothness of air intake.

[0078] Specifically, the material of the airway tube 41 is not limited. It can be made of heat-insulating material 91 or a metal material with good thermal conductivity, such as stainless steel, aluminum alloy, copper, etc. There are no restrictions here. Please refer to the relevant documentation. Figure 9 In some embodiments, the air duct 41 is supported by a metal material with good thermal conductivity, so that the heat from the heating module 20 can be better directed into the air intake channel 44 to preheat the gas.

[0079] The specific implementation of the first airway structure is not limited; it can be an integrated whole or a combination of multiple components, etc., and is not limited here.

[0080] Please see Figures 1 to 4 , Figure 7 and Figure 8 as well as Figure 12In some embodiments, the first air passage structure includes a sealing tube 51 and a first mounting bracket 60. The sealing tube 51 is disposed inside the air passage pipe 41 and is at least partially spaced from the pipe wall of the air passage pipe 41. The sealing tube 51 is sleeved on the outside of the heating module 20. The first mounting bracket 60 is disposed through the middle to connect the heating channel 21 and the cigarette channel 11. An annular rib 62 protrudes from the outside of the first mounting bracket 60. The annular rib 62 abuts against the top end of the sealing tube 51. An air inlet 61 is opened at the top end of the first mounting bracket 60, and an air passage groove 63 is provided at the annular rib 62 to guide the airflow from the cigarette channel 11 to the air inlet channel 44 through the air inlet 61 and the air passage groove 63.

[0081] In the scheme of this embodiment, when the user smokes the cigarette, a negative pressure is generated in the heating channel 21. At this time, since the heating channel 21 and the air intake channel 44 are connected, under the action of the negative pressure, the gas in the air intake channel 44 will move into the heating channel 21. Furthermore, the air will reach the air intake hole 61 at the top of the first mounting bracket 60 through the gap between the cigarette and the cigarette channel 11, enter through the air intake hole 61, pass through the air passage 63, and enter the air intake channel 44.

[0082] Please refer to this carefully. Figure 12 The sealing tube 51 is disposed inside the air passage 41 and is at least partially spaced from the wall of the air passage 41. The sealing tube 51 is sleeved on the outside of the heating module 20, which can seal the heating module 20 to prevent the high-temperature flue gas in the heating channel 21 of the heating module 20 from moving into the air intake channel 44, and also prevent the gas in the air intake channel 44 from directly entering the heating channel 21.

[0083] The annular rib 62 is abutting against the top end of the sealing tube 51, which can fix the sealing tube 51 on the one hand, and enhance the isolation effect between the air intake channel 44 and the heating channel 21 on the other hand.

[0084] In addition, in some embodiments, a sealing gasket 80 is provided between the cover 10 and the air passage 41, which can improve the airtightness of the air intake passage 44.

[0085] Please refer to the following: Figure 13 and Figure 14In some embodiments, the first airway structure further includes a second mounting bracket 70, the bottom end face of which is provided with an inverted buckle 71 for assembling the sealing tube 51 and limiting the gap between the sealing tube 51 and the airway tube 41.

[0086] Specifically, the second mounting bracket 70 can be made of a material that is resistant to high temperatures and has low thermal conductivity, such as PEEK, PI, PPSU, etc.

[0087] Please refer to the following: Figure 7 and Figure 8 , Figure 3 and Figure 4 In some embodiments, the first mounting bracket 60 is located within the sealing tube 51 and is provided with a mounting groove 64. The first air passage structure also includes a sealing ring 65 disposed within the mounting groove 64. This arrangement can further improve the sealing effect on the heating module 20.

[0088] Specifically, the form of the sealing ring 65 is not limited; it can be a rubber ring, a silicone ring, etc., and is not limited here.

[0089] Please refer to this carefully. Figure 12 In some embodiments, the outer periphery of the sealing tube 51 is provided with an air passage rib 52, and the air passage rib 52 is provided with a plurality of air passage grooves 53. With this arrangement, the air passage rib 52 can, on the one hand, position the sealing tube 51, and on the other hand, divide the air intake channel 44 into several small channels, thereby improving the uniformity of air intake.

[0090] Specifically, the number of the plurality of ventilation slots 53 is not limited, and can be two, three, four, etc., which is not limited here. The plurality of ventilation slots 53 can be evenly distributed at equal intervals or can be non-uniformly distributed, which is not limited here.

[0091] It should be noted that the air intake channel 44 is connected to the heating channel 21. This connection could be with the middle of the heating channel 21, or with the bottom of the heating channel 21, etc., and is not limited here.

[0092] In some embodiments, the air intake channel 44 is connected to the bottom of the heating channel 21, and the air passage rib 52 is positioned near the bottom of the sealing tube 51.

[0093] Please refer to this carefully. Figures 2 to 4 and Figure 7In some embodiments, the first mounting bracket 60 has an annular baffle 66 at its through-hole portion, and the annular baffle 66 is disposed above the heating module 20.

[0094] It should be noted that in some embodiments, the heating module 20 is made of PI film. Specifically, the PI film is provided with a heating circuit. The heating circuit can be printed directly on the PI film, or the heating circuit composed of heating wires can be bonded to the PI film with hot melt adhesive, etc., and then the PI film is rolled up to form the heating module 20. In this case, during the process of smoking, once the cigarette comes into contact with the end of the heating module 20, the PI film is easy to separate, resulting in poor long-term stability of the heating module 20.

[0095] In the scheme of this embodiment, by setting the annular baffle 66, on the one hand, it can play a certain sealing role for the heating channel 21, thereby preventing the air intake of the cigarette channel 11 from directly entering the heating channel 21. On the other hand, it can play a shielding and protective role for the end of the heating module 20, preventing damage to the end of the heating module 20 during the process of cigarette extraction.

[0096] In some embodiments, the electronic cigarette device 100 further includes an electrical component installed in the mounting cavity of the housing 30 and located outside the air passage tube 41; the bottom of the air passage tube 41 is provided with an assembly hole 43, a sealing plug 42 is provided in the assembly hole 43, and the sealing plug 42 forms a wire hole 421.

[0097] In the solution of this embodiment, since the airflow path is entirely located in the upper space of the product, the air duct does not need to penetrate the entire body. Therefore, the electrical components can be placed in other positions of the product, thereby improving the local structure of the product.

[0098] Specifically, this can involve stacking the battery and other components such as the PCBA in the lower space, thus improving the structural layout.

[0099] By setting the sealing plug 42 and the wire hole 421, the wire harness can pass through the wire hole 421 to connect the electrical components and the heating module 20, etc. The sealing plug 42 can play a certain sealing role for the wire harness, and avoid the airflow path from being affected by the wiring.

[0100] For more specific details, please refer to the following: Figure 11 and Figure 12The sealing plug 42 can be made of silicone material with a temperature resistance of over 200°C. The sealing plug 42 is provided with a wire hole 421 for the heating tube lead and the temperature sensor lead to pass through. The bottom of the wire hole 421 has a thin wall of 0.15mm thickness that is not penetrated. During assembly, the lead pierces through the thin wall and passes out of the hole.

[0101] The number of wire holes 421 is not limited and can be any number set according to actual needs, etc., and is not limited here.

[0102] In some embodiments, the first air passage structure is at least partially spaced from the heating module 20 to form a heat insulation cavity 90 between the first air passage structure and the heating module 20.

[0103] In the solution of this example, by forming the heat insulation cavity 90, the heat loss of the heating module 20 can be effectively reduced.

[0104] More specifically, the insulation cavity 90 can be filled with insulation material 91, thereby preventing convective heat transfer in the insulation cavity 90 and further improving the insulation effect on the heating module 20.

[0105] In some embodiments, the electronic cigarette device 100 further includes a temperature detector 92 for detecting the temperature at the air inlet of the heating channel 21.

[0106] It is understandable that during the user's suction process, after the air in the original air intake channel 44 enters the heating channel 21, when the new gas enters the heating channel 21 from the air intake channel 44, the temperature at the air intake of the heating channel 21 will decrease, and each temperature decrease can be regarded as a suction process.

[0107] In the scheme of this embodiment, by setting the temperature detector 92, the temperature detector 92 is used to detect the temperature at the air inlet of the heating channel 21, thereby detecting and recording the temperature change at the air inlet of the heating channel 21, and then recording the number of times the user sucks. The user can clearly identify the usage record when using it, thus improving the user experience.

[0108] The electronic cigarette device 100 provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
