Description

Technical Field

[0001] The present application relates to the technical field of smoking articles, and in particular to a heat-not-burn device with high internal conductivity. Background Art

[0002] Existing heat-not-burn smoking devices include a heating chamber with a heating needle made of metal material in the center of the heating chamber. A heating source is set at the bottom of the heating chamber, and the heating needle is placed on the upper surface of the heating source. When the heating source is energized, heat is generated. The heat is transferred to the heating needle and conducted upward along the heating needle to heat the tobacco in the heating chamber; or the heating source is set inside the heating needle. When the heating source is energized, heat is generated, and the heat flows on the heating needle through metal conduction. The above-mentioned heating method of heat conduction through metal has the following disadvantages: 1. The heat conduction rate is slow; 2. Since the heating needle is in direct contact with the tobacco, it is easy to cause heat loss during the conduction process. Finally, too little heat reaches the top of the heating needle, resulting in too little heat on the upper part of the tobacco, or the upper part of the tobacco cannot be heated. The temperature at the bottom of the heating needle is very high, but the temperature at the top of the heating needle is very low, causing the tobacco at the bottom to burn, while the tobacco at the top has not been heated and atomized, and the aroma has not evaporated. Summary of the Invention

[0003] The embodiments of the present application provide a heat-not-burn device with high internal conductivity, which solves the problem that existing heat-not-burn smoking devices have a slow heating rate and cannot heat tobacco evenly.

[0004] The present invention is implemented as follows: a heating-without-burning device with high internal conductivity performance includes a base, a cigarette holding tube, a heater and a gas-liquid phase-change heat pipe; the cigarette holding tube is used to hold tobacco, and the cigarette holding tube is arranged on the base; the heater is arranged on the base; the gas-liquid phase-change heat pipe includes an evaporation zone, a convection zone and a condensation zone, the evaporation zone is in contact with the heater, and the condensation zone is used to penetrate into the interior of the tobacco to heat the tobacco.

[0005] According to the heating-without-combustion device with high internal conductivity provided in the embodiment of the present application, the heater contacts the evaporation zone of the gas-liquid phase change heat pipe to heat the evaporation zone of the gas-liquid phase change heat pipe, thereby allowing heat to circulate in the gas-liquid phase change heat pipe. Since the condensation zone of the gas-liquid phase change heat pipe penetrates into the interior of the tobacco, the gas-liquid phase change heat pipe can heat all positions of the tobacco at a uniform temperature; and since the thermal conductivity coefficient of the gas-liquid phase change heat pipe is relatively high, the use of the gas-liquid phase change heat pipe can quickly heat the tobacco, thereby improving the heating efficiency.

[0006] In one embodiment, a receiving cavity is provided inside the heater, and one end of the receiving cavity close to the base is closed, and the receiving cavity is used to receive the evaporation region of the gas-liquid phase change heat pipe.

[0007] In one embodiment, a receiving hole is provided inside the heater and passes through the heater, and the receiving hole is used to receive the evaporation region of the gas-liquid phase change heat pipe.

[0008] In one embodiment, the heater contacts the end surface of the evaporation zone of the gas-liquid phase change heat pipe.

[0009] In one embodiment, the gas-liquid phase change heat pipe is in the shape of a cylindrical needle, and the evaporation region of the gas-liquid phase change heat pipe is in the shape of a cylinder.

[0010] In one embodiment, the base has an air flow channel connecting the cigarette holding tube and the outside.

[0011] In one embodiment, the base includes a fixing seat and an airflow channel member;

[0012] Both ends of the fixing seat are open;

[0013] The airflow channel component is detachably mounted on the fixing seat. The airflow channel component includes a plurality of airflow channels, and the airflow channels are used to connect the cigarette accommodating tube with the outside world.

[0014] In one embodiment, the airflow channel member includes a cylindrical mounting tube and a plurality of radially distributed partitions extending from an outer side of the cylindrical mounting tube;

[0015] A plurality of slots are provided on the inner side of the fixing base, and the plurality of partitions are inserted into the plurality of slots in a one-to-one correspondence, and the air flow channel is formed between two adjacent partitions and the inner side of the fixing base;

[0016] The heater is disposed in the cylindrical mounting tube.

[0017] In one embodiment, the heat-not-burn device further includes a heat-insulating tube, which is disposed on the fixing seat and sleeved on the outer periphery of the cigarette receiving tube.

[0018] In one embodiment, the heating without burning device further includes an outer shell, which is sleeved on the outer circumference of the insulation tube.

[0019] The beneficial effect of the heating-not-burning device with high internal conductivity provided by the present application is that: compared with the existing technology, the present application heats the evaporation zone of the gas-liquid phase change heat pipe by contacting the heater with the evaporation zone of the gas-liquid phase change heat pipe, and penetrates the condensation zone of the gas-liquid phase change heat pipe into the interior of the tobacco, thereby utilizing the gas-liquid phase change heat pipe to heat the tobacco. Since the thermal conductivity coefficient of the gas-liquid phase change heat pipe is relatively high, the use of the gas-liquid phase change heat pipe can quickly heat the tobacco and improve the heating efficiency; when the evaporation zone of the gas-liquid phase change heat pipe is heated, circulating heat will be formed in the gas-liquid phase change heat pipe to maintain the temperature of the entire gas-liquid phase change heat pipe uniform, so that the gas-liquid phase change heat pipe can heat each position of the tobacco at a uniform temperature, ensuring that the user's taste remains consistent during the process of the tobacco being gradually atomized.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] It should also be noted that, in the embodiments of the present application, the same figure mark represents the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0041] The embodiments of the present application provide a heat-not-burn device with high internal conductivity, which solves the problem that existing heat-not-burn smoking devices have a slow heating rate and cannot heat tobacco evenly.

[0042] Example 1

[0043] refer to Figure 1-Figure 2 The heating-not-burning device with high internal conductivity provided in the first embodiment of the present application includes a base 10, a cigarette holding tube 20, a heater 30 and a gas-liquid phase change heat pipe 40; the cigarette holding tube 20 is used to hold tobacco 100, and the cigarette holding tube 20 is arranged on the base 10; the heater 30 is arranged on the base 10; the gas-liquid phase change heat pipe 40 includes an evaporation zone, a convection zone and a condensation zone, the evaporation zone is in contact with the heater 30, and the condensation zone is used to penetrate into the interior of the tobacco 100 to heat the tobacco 100.

[0044] Specifically, the gas-liquid phase change heat pipe 40 in the embodiment of the present application utilizes the heat conduction principle and the rapid heat transfer property of the phase change medium to quickly transfer the heat of the heating object to the outside of the heat source through the heat pipe. Its thermal conductivity exceeds that of any known metal.

[0045] refer to Figure 8 The gas-liquid phase change heat pipe 40 generally includes a sealed tube body 401 and a capillary structure layer 402 arranged close to the inner wall of the tube body 401. The capillary structure layer 402 stores a phase change liquid 403. The gas-liquid phase change heat pipe 40 is divided into an evaporation section (evaporation zone), a convection section (convection zone) and a condensation section (condensation zone) which are connected in sequence. Figure 9-10The phase change liquid 403 is adsorbed by the capillary structure layer 402. When the external temperature changes slightly, the phase change liquid 403 adheres to the capillary structure layer 402. When the gas-liquid phase change heat pipe 40 is locally heated, heat is transmitted to the heated part, making the internal temperature of the gas-liquid phase change heat pipe 40 higher and higher until the phase change liquid 403 inside it vaporizes and forms steam. This area is the evaporation area. Due to the generation of steam, the pressure in the evaporation area increases, squeezing the steam to other areas, causing the steam to flow. The area through which the steam flows is the convection area. After passing through the convection area, the steam finally reaches another area of the gas-liquid phase change heat pipe 40, which is the condensation area. After the steam in the gas-liquid phase change heat pipe 40 enters the condensation area, the temperature drops, heat is released and liquefied to form phase change liquid 403. In this way, the heat introduced into the gas-liquid phase change heat pipe 40 is transmitted to the unheated part of the gas-liquid phase change heat pipe 40 as the liquid-gas conversion inside the gas-liquid phase change heat pipe 40 is carried out, and diffused out of the gas-liquid phase change heat pipe 40 as the gas-liquid conversion is carried out. Figure 9 The figure shows a schematic diagram of heat flow in a gas-liquid phase change heat pipe. As the phase change liquid 403 in the evaporation zone turns into vapor, a negative pressure is formed in the capillary structure layer 402 in this area, and the phase change liquid 403 in the capillary structure layer 402 in the adjacent area is sucked into the evaporation zone. Ultimately, a vapor flow path is formed from the evaporation zone to the convection zone and then to the condensation zone, and a phase change liquid 403 flow path is formed from the condensation zone to the convection zone and then to the evaporation zone, forming a closed liquid-vapor cycle. Figure 10 The figure shows a schematic diagram of gas-liquid circulation in the gas-liquid phase change heat pipe. This circulation process enables the gas-liquid phase change heat pipe 40 to quickly transfer heat in a desired manner and direction.

[0046] It should be noted that Figures 8-10 The figures shown are used to explain the working principle of the gas-liquid phase change heat pipe 40. The shape of the gas-liquid phase change heat pipe in the embodiment of the present application is not limited to Figures 8-10 The shape of the gas-liquid phase change heat pipe shown in FIG.

[0047] The gas-liquid phase change heat pipe 40 used in the embodiment of the present application is a medium temperature (150-300° C.) micro heat pipe.

[0048] It should be noted that the heater 30 is used to generate heat, and the heater 30 can generate heat by resistive heating, electromagnetic induction heating, ignition heating, microwave heating, etc.

[0049] The heating-not-burning device with high internal conductivity provided by the embodiment of the present application is different from the prior art. The heater 30 does not directly heat the tobacco 100, but first contacts the evaporation zone of the gas-liquid phase change heat pipe 40 through the heater 30 to heat the evaporation zone of the gas-liquid phase change heat pipe 40. When the evaporation zone of the gas-liquid phase change heat pipe 40 is heated, heat is transmitted, and the phase change liquid 403 in this part of the gas-liquid phase change heat pipe 40 is heated and converted into steam and flows to the condensation zone of the gas-liquid phase change heat pipe 40. After the steam in the gas-liquid phase change heat pipe 40 enters the condensation zone, the temperature drops, releasing heat and turning into phase change liquid 403. In this way, the heat will be quickly dissipated from the condensation zone of the gas-liquid phase change heat pipe 40 and transferred to the tobacco 100. At this time, the gas-liquid phase change heat pipe 40 assumes the function of transferring heat. The gas-liquid phase change heat pipe 40 transfers heat very quickly and the efficiency is very high. The use of the gas-liquid phase change heat pipe 40 can quickly heat the tobacco 100 and evaporate the aroma in the tobacco 100. Since heat flows continuously in the gas-liquid phase change heat pipe 40, the temperature at each position of the gas-liquid phase change heat pipe 40 can be basically kept consistent. The condensation zone of the gas-liquid phase change heat pipe 40 in the embodiment of the present application penetrates into the interior of the tobacco 100. In this way, the gas-liquid phase change heat pipe 40 can heat each position of the tobacco 100 at a uniform temperature, so that the taste of the user can remain consistent during the gradual atomization process of the tobacco 100.

[0050] refer to Figure 1-Figure 2 The heater 30 in the first embodiment of the present application is provided with an accommodating cavity inside, and the accommodating cavity is closed at one end close to the base 10 , and the accommodating cavity is used to accommodate the evaporation area of the gas-liquid phase change heat pipe 40 .

[0051] It should be noted that a accommodating cavity is provided inside the heater 30, and the accommodating cavity is closed at one end close to the base 10. In this way, after the evaporation zone of the gas-liquid phase change heat pipe 40 is placed in the accommodating cavity, the end face and side face of the evaporation zone of the gas-liquid phase change heat pipe 40 are all in contact with the heater 30, which greatly increases the contact area between the heater 30 and the evaporation zone of the gas-liquid phase change heat pipe 40, further improves the heating rate, and can quickly transfer heat into the gas-liquid phase change heat pipe 40 to quickly heat the tobacco 100. In addition, since the accommodating cavity is closed at one end close to the base 10, when installing the heating without burning device with high internal conductivity of the embodiment of the present application, when inserting the condensation zone of the gas-liquid phase change heat pipe 40 into the accommodating cavity, there is no need to worry about the evaporation zone of the gas-liquid phase change heat pipe 40 passing through the heater 30, so that the heater 30 cannot accurately heat the evaporation zone of the gas-liquid phase change heat pipe 40, and the installation difficulty is reduced.

[0052] In the first embodiment of the present application, the gas-liquid phase change heat pipe 40 is in the shape of a cylindrical needle, and the evaporation zone of the gas-liquid phase change heat pipe 40 is in the shape of a cylinder. Correspondingly, the heater 30 can be set to a circular tube shape, and the heater 30 is closed at one end close to the base 10 and open at the other end. In this way, a accommodating cavity can be formed inside the heater 30. In order to make the evaporation zone of the gas-liquid phase change heat pipe 40 fit tightly with the heater 30 and improve the heat conduction efficiency, the diameter of the evaporation zone of the gas-liquid phase change heat pipe 40 can be set to be the same as the inner diameter of the heater 30, so that the evaporation zone of the gas-liquid phase change heat pipe 40 is gap-matched with the heater 30, but the gap is zero. The other end of the gas-liquid phase change heat pipe 40 is needle-shaped, and the needle-shaped end penetrates into the interior of the tobacco 100. Since the user needs to insert the tobacco 100 from the end of the cigarette holding tube 20 away from the base 10 when using the heat-not-burn device with high internal conductivity of the embodiment of the present application, at this time, since the other end of the gas-liquid phase change heat pipe 40 is needle-shaped, it is convenient for the user to quickly insert the tobacco 100 until it contacts the heater 30, and the tobacco 100 will not encounter obstacles and break during the insertion process.

[0053] Example 2

[0054] refer to Figure 3 In the second embodiment of the present application, a receiving hole is provided inside the heater 30 and passes through the heater 30 . The receiving hole is used to receive the evaporation zone of the gas-liquid phase change heat pipe 40 .

[0055] It should be noted that a receiving hole is provided inside the heater 30 and passes through the heater 30. After the evaporation zone of the gas-liquid phase change heat pipe 40 is placed in the receiving hole, the side of the evaporation zone of the gas-liquid phase change heat pipe 40 is in contact with the heater 30. The heat generated by the heater 30 is transmitted into the gas-liquid phase change heat pipe 40 through the side of the evaporation zone of the gas-liquid phase change heat pipe 40. It should be noted that since the receiving hole passes through the heater 30, the evaporation zone of the gas-liquid phase change heat pipe 40 must be ensured to be in contact with the heater 30 when inserted into the receiving hole, and will not fall out of the receiving hole.

[0056] In the second embodiment of the present application, the gas-liquid phase change heat pipe 40 is a cylindrical needle shape, and the evaporation zone of the gas-liquid phase change heat pipe 40 is cylindrical. Correspondingly, the heater 30 can be set to a circular tube shape, and both ends of the heater 30 are open, so that a receiving hole can be formed inside the heater 30. In order to make the evaporation zone of the gas-liquid phase change heat pipe 40 fit tightly with the heater 30 and improve the heat conduction efficiency, the diameter of the evaporation zone of the gas-liquid phase change heat pipe 40 can be set to the same as the inner diameter of the heater 30, so that the evaporation zone of the gas-liquid phase change heat pipe 40 is gap-matched with the heater 30, but the gap is zero. In this way, it can ensure that the evaporation zone of the gas-liquid phase change heat pipe 40 is in close contact with the heater 30, and the position of the gas-liquid phase change heat pipe 40 can be fixed and will not fall out of the receiving hole of the heater 30. The other end of the gas-liquid phase change heat pipe 40 is needle-shaped, and the needle-shaped end penetrates into the interior of the tobacco 100. Since the user needs to insert the tobacco 100 from the end of the cigarette holding tube 20 away from the base 10 when using the heat-not-burn device with high internal conductivity of the embodiment of the present application, at this time, since the other end of the gas-liquid phase change heat pipe 40 is needle-shaped, it is convenient for the user to quickly insert the tobacco 100 until it contacts the heater 30, and the tobacco 100 will not encounter obstacles and break during the insertion process.

[0057] Example 3

[0058] refer to Figure 4 The heater 30 in the third embodiment of the present application contacts the end surface of the evaporation zone of the gas-liquid phase change heat pipe 40 .

[0059] It should be noted that the heater 30 is in contact with the end face of the evaporation zone of the gas-liquid phase change heat pipe 40. In this way, the heat generated by the heater 30 is transferred into the gas-liquid phase change heat pipe 40 from the end face of the evaporation zone of the gas-liquid phase change heat pipe 40. During installation, the gas-liquid phase change heat pipe 40 only needs to be placed on the heater 30 so that the end face of the evaporation zone of the gas-liquid phase change heat pipe 40 contacts the heater 30. This prevents the gas-liquid phase change heat pipe 40 from falling out of the heater 30. It is worth noting that the gas-liquid phase change heat pipe 40 needs to penetrate the interior of the tobacco 100. Therefore, the gas-liquid phase change heat pipe 40 needs to be fixed and kept stable so that the condensation zone of the gas-liquid phase change heat pipe 40 can penetrate the interior of the tobacco 100 when the tobacco 100 is inserted into the cigarette holding tube 20. A support member can be provided on the heater 30. This support member is located between the heater 30 and the gas-liquid phase change heat pipe 40 to support and stabilize the gas-liquid phase change heat pipe 40 and prevent heat from being transferred to the gas-liquid phase change heat pipe 40.

[0060] In the third embodiment of the present application, the gas-liquid phase change heat pipe 40 is a cylindrical needle shape, and the evaporation zone of the gas-liquid phase change heat pipe 40 is cylindrical. Correspondingly, the heater 30 can be set to a solid cylindrical shape, and the diameter of the heater 30 can be set to be smaller than the diameter of the heating end of the gas-liquid phase change heat pipe 40. As long as the end face of the evaporation zone of the gas-liquid phase change heat pipe 40 remains in contact with the heater 30, it can be ensured that the heat generated by the heater 30 is transferred from the end face of the evaporation zone of the gas-liquid phase change heat pipe 40 to the gas-liquid phase change heat pipe 40; the diameter of the heater 30 can also be set to be equal to or larger than the diameter of the evaporation zone of the gas-liquid phase change heat pipe 40. In this way, heat can be transferred from the entire end face of the evaporation zone of the gas-liquid phase change heat pipe 40 to the gas-liquid phase change heat pipe 40, greatly improving the heat conduction rate. The other end of the gas-liquid phase change heat pipe 40 is needle-shaped, and the needle-shaped end penetrates into the interior of the tobacco 100. Since the user needs to insert the tobacco 100 from the end of the cigarette holding tube 20 away from the base 10 when using the heat-not-burn device with high internal conductivity of the embodiment of the present application, at this time, since the other end of the gas-liquid phase change heat pipe 40 is needle-shaped, it is convenient for the user to quickly insert the tobacco 100 until it contacts the heater 30, and the tobacco 100 will not encounter obstacles and break during the insertion process.

[0061] In the above-mentioned embodiments 1 to 3, reference is made to Figure 6 The base 10 has an air flow channel 101 connecting the cigarette receiving tube 20 and the outside.

[0062] It can be understood that the base 10 of the embodiment of the present application has an air flow channel 101 connecting the cigarette holding tube 20 and the outside world, so that the external gas can be transmitted upward through the air flow channel 101, enter the cigarette holding tube 20, flow upward from the tobacco 100, flow out from the upper part of the tobacco 100, and enter the oral cavity. In this way, not only can the aroma generated by the heated and atomized tobacco 100 flow into the oral cavity along with the gas, enhancing the user's smoking taste, but the air flow channel 101 between the cigarette holding tube 20 and the outside world also makes it easier for users to smoke cigarettes. In addition, since the heating-not-burning device with high internal conductivity in the embodiment of the present application heats the tobacco 100 to generate smoke, the temperature of the smoke at this time is relatively high and is not suitable for the user to inhale directly. It is necessary to wait for a certain period of time before inhaling, which can easily reduce the user's experience. The setting of the airflow channel 101 in the embodiment of the present application allows the user to introduce low-temperature external air when inhaling the smoke atomized from the tobacco 100, which can cool the high-temperature smoke. The user can inhale the smoke from the tobacco 100 at any time without waiting, and the experience is stronger.

[0063] In the above-mentioned embodiments 1 to 3, reference is made to Figure 1-Figure 4The base 10 includes a fixing seat 11 and an air flow channel member 12; both ends of the fixing seat 11 are open; the air flow channel member 12 is detachably arranged on the fixing seat 11, and the air flow channel member 12 includes a plurality of air flow channels 101, which are used to connect the cigarette holding tube 20 and the outside world.

[0064] It should be noted that the heater 30 of the present application is arranged on the base 10, specifically on the fixed seat 11. In this way, when the heater 30 is turned on to generate heat, the temperature of the fixed seat 11 will also increase. In this way, the user may be burned when holding the heating-not-burning device with high internal conductivity of the embodiment of the present application. Therefore, the fixed seat 11 can be made of insulating material, or a thermal insulation layer can be arranged on the outer periphery of the fixed seat 11, which can not only insulate and prevent the user from touching the fixed seat 11 and being burned, but also keep warm to prevent the heat generated by the heater 30 from dissipating from the fixed seat 11, resulting in the inability to quickly heat the gas-liquid phase change heat pipe 40.

[0065] It can be understood that the fixing seat 11 or the insulation layer can be made of insulation materials. The insulation materials mainly refer to materials or material composites with insulation properties that can shield heat flow. They are usually light, loose, porous, and have low thermal conductivity. They are widely used in industry to prevent heat loss in thermal equipment and pipelines, or are used under freezing and low temperature conditions. Therefore, they are also called thermal insulation or cold insulation materials.

[0066] Specifically, the fixing seat 11 of the present application can be a structure in which two circular tubes are connected together, wherein the inner diameters of the two circular tubes are the same and the outer diameters are different, and the setting position of the heater 30 inside the fixing seat 11 is located in the circular tube with smaller outer diameter or in the circular tube with smaller outer diameter and the circular tube with larger outer diameter. In this way, at least a part of the circular tube with larger outer diameter of the fixing seat 11 is hollow, and its temperature is very low. Moreover, the wall thickness of the circular tube with larger outer diameter is also larger, which further improves the heat insulation effect of the fixing seat 11, and the user will not be burned when holding it. Moreover, the part of the fixing seat 11 that does not contact the heater 30 will facilitate the passage of outside air into the cigarette holding tube 20. The airflow channel member 12 is detachably arranged on the fixing base 11. The airflow channel member 12 is specifically arranged inside the fixing base 11. The airflow channel member 12 abuts against the inner wall of the fixing base 11, and can play the role of supporting the cigarette holding tube 20 and the heater 30; the airflow channel member 12 includes a plurality of airflow channels 101, which can enable the external air to evenly enter the tobacco 100 when the user smokes the tobacco 100 and enter the user's mouth with the aroma generated by the atomization of the tobacco 100, thereby enhancing the user's taste of smoking the tobacco 100; in addition, the uniform entry of the external air into the tobacco 100 can also uniformly cool the high-temperature smoke, effectively improving the user's experience of smoking the tobacco 100.

[0067] In the above-mentioned embodiments 1 to 3, reference is made to Figure 1 The air flow channel component 12 includes a cylindrical mounting tube 121 and a plurality of radially distributed partitions 122 extending from the outer side of the cylindrical mounting tube 121; a plurality of slots 111 are provided on the inner side of the fixing seat 11, and the plurality of partitions 122 are respectively inserted into the plurality of slots 111 in a one-to-one correspondence, and an air flow channel 101 is formed between two adjacent partitions 122 and the inner side of the fixing seat 11; the heater 30 is arranged in the cylindrical mounting tube 121.

[0068] Specifically, the air flow channel member 12 in the present application includes a cylindrical mounting tube 121 and a plurality of radially distributed partitions 122 extending from the outer side of the cylindrical mounting tube 121. The heater 30 is arranged in the cylindrical mounting tube 121. When the heater 30 is a circular tube, the heater 30 can be gap-fitted with the cylindrical mounting tube 121, wherein the end of the cylindrical mounting tube 121 away from the heater 30 can be closed, so that the heater 30 will not fall out after being set in the cylindrical mounting tube 121. Of course, the end of the cylindrical mounting tube 121 away from the heater 30 can also be opened, so that the gap between the heater 30 and the cylindrical mounting tube 121 is zero.

[0069] The airflow channel component 12 is arranged inside the fixing seat 11, specifically, a plurality of slots 111 are set on the inner side of the fixing seat 11, and the plurality of partitions 122 of the airflow channel component 12 are respectively inserted into the plurality of slots 111 one by one, so that the connection between the airflow channel component 12 and the fixing seat 11 can be achieved, wherein the depth of the slot 111 should be smaller than the radial length of the partition 122 in the cylindrical mounting tube 121, so as to ensure that there is a certain gap between the inner side of the fixing seat 11 and the outer side of the cylindrical mounting tube 121 and they will not contact each other, so that an airflow channel 101 can be formed between the two adjacent partitions 122 and the inner side of the fixing seat 11, ensuring that the external gas enters the cigarette holding tube 20 from the airflow channel 101, thereby improving the user's experience of smoking tobacco 100.

[0070] Optionally, based on the structural setting of the above-mentioned air flow channel member 12, the height of the heater 30 in Examples 1 to 2 of the present application can be equal to the height of the cylindrical mounting tube 121, so as to ensure that the heater 30 is installed more stably. Of course, the height of the heater 30 can also be greater than the height of the cylindrical mounting tube 121, so as to increase the contact area between the heater 30 and the evaporation zone of the gas-liquid phase change heat pipe 40, thereby improving the heating efficiency of the gas-liquid phase change heat pipe 40.

[0071] Example 4

[0072] refer to Figure 5In the fourth embodiment of the present application, a coated heating or silk-screened resistor can be used as the heater 30, and the heater 30 is coated on the outer side of the evaporation zone of the gas-liquid phase change heat pipe 40. It should be noted that the cylindrical mounting tube 121 of the airflow channel member 12 in the fourth embodiment of the present application is closed at both ends, the gas-liquid phase change heat pipe 40 is placed on the cylindrical mounting tube 121, and then a coated heating or silk-screened resistor is used to coat the outer side of the evaporation zone of the gas-liquid phase change heat pipe 40. In this way, the gas-liquid phase change heat pipe 40 can be inserted into the tobacco 100 as a whole, and the condensation zone of the gas-liquid phase change heat pipe 40 is closer to the filter part of the tobacco 100, so that the tobacco 100 as a whole can be heated more evenly, and the aroma evaporated from each position of the tobacco 100 can be kept consistent. The user's taste is consistent from the beginning to the end of the process of smoking the tobacco 100, which improves the user's experience of smoking the tobacco 100.

[0073] Optionally, a baffle is provided inside the cylindrical mounting tube 121 of the airflow channel member 12 in the fourth embodiment of the present application, so that a fixed cavity is formed inside the cylindrical mounting tube 121. The height of the fixed cavity is very small, and the evaporation zone of the gas-liquid phase change heat pipe 40 is placed in the fixed cavity, and then the heater 30 is covered on the part of the evaporation zone of the gas-liquid phase change heat pipe 40 located outside the fixed cavity. This not only makes the placement of the gas-liquid phase change heat pipe 40 more stable and convenient for insertion into the tobacco 100, but also the height of the fixed cavity is very small, which will not affect the heating effect of the heater 30 on the evaporation zone of the gas-liquid phase change heat pipe 40.

[0074] The airflow channel schematic diagrams in Examples 1 to 4 of the present application can be referred to Figure 6 .

[0075] In the above-mentioned embodiments 1 to 4, reference is made to Figure 1-Figure 5 、 Figure 7 The heat-not-burn device with high internal conductivity also includes an insulation tube 50 , which is disposed on the fixing seat 11 and sleeved on the outer periphery of the cigarette receiving tube 20 .

[0076] It should be noted that the heating without burning device with high internal conductivity in the embodiment of the present application is provided with an insulation tube 50, and the insulation tube 50 is sleeved on the outer periphery of the cigarette receiving tube 20, which can effectively maintain the temperature in the cigarette receiving tube 20 to be balanced. At the same time, the heat loss in the cigarette receiving tube 20 is very slow, which can also reduce the power consumed by the heater 30 and reduce unnecessary power consumption. Since the heater 30 is arranged inside the fixing seat 11, the insulation tube 50 can be arranged on the fixing seat 11. Specifically, a groove can be provided on the outer side surface of the fixing seat 11, and a convex strip can be provided on the inner side surface of the insulation tube 50. The convex strip can be clamped in the groove to achieve the installation of the insulation tube 50 on the fixing seat 11, and the insulation tube 50 can also be fixed; or a convex strip can be provided on the outer side surface of the fixing seat 11, and a groove can be provided on the inner side surface of the insulation tube 50. The convex strip can be clamped in the groove to achieve the installation of the insulation tube 50 on the fixing seat 11, and the insulation tube 50 can also be fixed. The above installation method is simple and convenient, which is conducive to the assembly of a heating non-combustion device with high internal conductivity.

[0077] It is understandable that the thermal insulation pipe 50 in the embodiment of the present application can be made of the same thermal insulation material as the fixing seat 11 and the thermal insulation layer.

[0078] Furthermore, the size of the opening provided at the end of the insulation tube 50 away from the fixed seat 11 is consistent with the size of the opening at the end of the cigarette receiving tube 20 away from the fixed seat 11, and the opening provided at the end of the insulation tube 50 away from the fixed seat 11 is directly opposite to the opening at the end of the cigarette receiving tube 20 away from the fixed seat 11, so as to ensure that the tobacco 100 passes through the opening on the insulation tube 50 and the opening on the cigarette receiving tube 20 and enters the cigarette receiving tube 20. The size of the opening provided on the insulation tube 50 can form a relatively closed space in the insulation tube 50 after the tobacco 100 is inserted into the cigarette receiving tube 20, thereby achieving a better insulation effect.

[0079] In the above-mentioned embodiments 1 to 4, reference is made to Figure 1-Figure 5 、 Figure 7 The heating without burning device with high internal conductivity performance also includes a shell 60, which is sleeved on the outer periphery of the insulation tube 50.

[0080] In the embodiment of the present application, the outer shell 60 is sleeved on the outer periphery of the insulation tube 50 to enhance the aesthetic appearance of the heating without burning device with high internal conductivity performance, and is also more convenient for users to hold.

[0081] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
