[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] Heated cigarettes are baked at low temperature by electric heating, wherein the contact area between the heat source and the cigarette is small, which easily causes the heat from the heat source to be unable to be smoothly transferred to the entire cigarette, thereby causing the temperature of the cigarette to be uneven. In this regard, the prior art provides a heat-conducting structure for heating cigarettes, wherein the interior of the heat-conducting structure is used to place cigarettes, and the heat-conducting structure is provided with a contact heating body for heating the cigarettes. In addition, an airflow heating body is also provided, which can preheat the gas entering the interior of the heat-conducting structure, and the heated gas enters the interior of the heat-conducting structure to uniformly heat the cigarettes. However, the problem is that it is necessary to provide a contact heating body and an airflow heating body at the same time, resulting in a complex overall structure and high processing costs.

[0054] In this regard, this embodiment provides a cigarette holder structure to solve the problem in the prior art that the heat-conducting structure needs to be provided with a contact heating body and an airflow heating body at the same time, resulting in a complex overall structure of the heat-conducting structure and high processing costs. It can be used in the field of heating cigarette smoking utensils technology.

[0055] Reference Figure 1-Figure 6 The cigarette holder structure includes a cigarette holder body 1, a heating element 2 and a heat conductor 3. The cigarette holder body 1 has a accommodating cavity 11 for accommodating cigarettes 100. The accommodating cavity 11 is connected to the outside through an airflow channel 12 so that gas can enter the accommodating cavity 11 from the airflow channel 12. The heating element 2 can generate heat and is used to heat the cigarettes 100 arranged in the accommodating cavity 11 so that the cigarettes 100 are heated to generate smoke. The heating element 2 is at least partially arranged in the accommodating cavity 11. The user inhales the gas in the accommodating cavity 11 into the body by inhaling. The heat conductive member 3 is arranged in the air flow channel 12 and is connected to the cigarette holder body 1. The heat conductive member 3 has an air hole 31 for gas to pass through. The heat conductive member 3 is made of a heat conductive material. The heat conductive member 3 cooperates with the heating element 2 so that the heat generated by the heating element 2 can be transferred to the heat conductive member 3. In the present embodiment, the two are directly connected, so that the heating element 2 can heat the heat conductive member 3 while heating the cigarette 100, thereby preheating the gas entering the accommodating chamber 11 through the air flow channel 12. The heated gas enters the accommodating chamber 11 and uniformly heats the cigarette 100. In addition, by providing a heat conductive member 3 connected to the heating element 2, the heating of the cigarette 100 and the preheating of the gas can be achieved simultaneously through only one heating source, and the structure is simple and the cost is low.

[0056] Specifically, the heat conducting member 3 has the following two structures:

[0057] One of them is Figure 1-Figure 3As shown, the heat conductive member 3 is plate-shaped and has a heating element connecting hole 32. The heating element 2 cooperates with the hole wall of the heating element connecting hole 32. The outer wall of the heat conductive member 3 is connected to the inner wall of the cigarette holder body 1. The heat emitted by the heating element 2 is first conducted to the hole wall of the connecting hole 32 and then conducted toward the outer wall of the heat conductive member 3, thereby heating the entire heat conductive member 3, so that the gas is heated when passing through the air vent 31.

[0058] Another kind of Figure 4-Figure 6 As shown, the heat-conducting member 3 includes a heat-conducting tube 33 in a cylindrical shape and a heat-conducting plate 34 connected to one end of the heat-conducting tube 33, the air-permeable hole 31 includes a first through hole 331 provided on the heat-conducting tube 33 and a second through hole 341 provided on the heat-conducting plate 34, the air flow channel 12 is connected to the inner cavity 332 of the heat-conducting tube 33 through the first through hole 331, and the inner cavity 332 of the heat-conducting tube 33 is connected to the accommodating cavity 11 through the second through hole 341, so that the gas is heated once when passing through the first through hole 331, and is heated twice when passing through the second through hole 341, so as to ensure that the temperature of the gas can meet the requirements. Among them, the heating element connecting hole 32 is opened on the heat-conducting plate 34, and the heating element 2 cooperates with the hole wall of the heating element connecting hole 32, so that the heat emitted by the heating element 2 is firstly conducted to the hole wall of the connecting hole 32, and then conducted to the heat-conducting plate 34 and the heat-conducting tube 33, so as to heat the entire heat-conducting member 3. Optionally, the smoke-lifting tube structure further comprises a structural member 4 connected to the heating element 2, the structural member 4 being arranged outside the accommodating cavity 11, and the end of the heat-conducting tube 33 away from the heat-conducting plate 34 abuts against the structural member 4, so that the heat-conducting plate 34, the heat-conducting tube 33 and the structural member 4 together enclose an inner cavity 332.

[0059] As another alternative, the heat-conducting tube 33 and the heat-conducting plate 34 can both be made of porous materials, and in this case, there is no need to set the air-permeable holes 31, making the structure simpler. The porous material can be a metal material, such as nickel, iron, copper, stainless steel, alloy, etc., or an inorganic non-metallic material, such as graphite, diamond, carbon nanotubes, carbon fiber, graphene, boron nitride, aluminum nitride, silicon carbide, aluminum oxide and zinc oxide, etc., or other polymer materials and composite materials.

[0060] Regardless of which solution is adopted, the heating element 2 is connected with the hole wall of the heating element connecting hole 32 in the following ways:

[0061] One of them is that the heating element 2 and the hole wall of the heating element connection hole 32 are interference fit, so that the two are fixedly connected, and the heat conduction effect is better. In addition, the heat conducting member 3 is fixedly connected to the cigarette holder body 1. In this scheme, the heating element 2, the heat conducting member 3 and the cigarette holder body 1 are all reliably connected, and the heat conducting member 3 heats up quickly, has a high temperature, and has a good preheating effect on the airflow.

[0062] The other is that the heating element 2 is matched with the hole wall of the heating element connection hole 32, so that the heating element 2 can be removed from the heating element connection hole 32. In addition, the heat conductive member 3 is fixedly connected to the cigarette holder body 1. In this solution, the heating element 2 is fixedly connected to the main part of the cigarette heating device, so that the heat conductive member 3 and the cigarette holder body 1 can be removed, which is convenient for cleaning.

[0063] Another method is that the heat-conducting member 3 is detachably connected to the cigarette holder body 1, specifically, the outer wall of the heat-conducting member 3 is gap-fitted with the inner wall of the cigarette holder body 1, and the heating element 2 is interference-fitted with the hole wall of the heating element connection hole 32, so that the two are fixedly connected. In this scheme, the cigarette holder body 1 can be removed from the main body of the cigarette heating device, which is convenient for cleaning the cigarette holder body 1, and because the heating element 2 is in direct contact with the hole wall of the heating element connection hole 32, the heat-conducting member 3 heats up quickly and has a high temperature, which is conducive to heating the airflow; the gas can pass through the gap between the heat-conducting member 3 and the cigarette holder body 1 or the air-permeable hole 31 on the heat-conducting member 3 to enter the interior of the accommodating cavity 11.

[0064] Continue to refer to Figure 1-Figure 6 The thermal conductivity of the material of the heat-conducting member 3 is not less than the thermal conductivity of the material of the heating element 2. By improving the thermal conductivity of the heat-conducting member 3, the heat generated by the heating element 2 can be transferred to the heat-conducting member 3 as much as possible. In this embodiment, the heat-conducting member 3 can be made of materials such as metal copper, aluminum alloy, stainless steel or graphene.

[0065] In this embodiment, the heating element 2 is provided with a plurality of air holes and a heating air flow channel is arranged inside. The air holes are connected with the heating air flow channel, and the heating air flow channel is connected with the air flow channel 12. The air flow can pass through the interior of the heating element 2. The gas inside the heating element 2 can contact with the interior of the heating element 2 to exchange heat, thereby heating the gas, and the heated gas flows to the accommodating cavity 11 through the air holes.

[0066] In other embodiments, the heating element 2 is in a solid column shape to increase the heat storage capacity of the heating element 2 and improve the temperature stability of the heating element 2. In other embodiments, the heating element 2 can be in other shapes, such as shaft, tube, sheet, etc.

[0067] Optionally, the end of the heating element 2 close to the cigarette 100 is tapered, which can guide the cigarette 100 to a certain extent, so as to facilitate the insertion of the cigarette 100, so that the cigarette 100 wraps the heating element 2, thereby improving the heating effect.

[0068] The structure of the cigarette holder still has the following problem: gas can only enter the accommodating chamber 11 of the cigarette holder body 1 through the airflow channel 12, and the accommodating chamber 11 needs to place the cigarette 100, resulting in poor gas flow effect inside the accommodating chamber 11. If the user turns on the heating element 2 but does not inhale for a long time, the heating element 2 will continue to heat the cigarette 100, and the heat cannot be dissipated, which may cause the temperature of the cigarette to continue to rise, and then burn the cigarette 100, affecting the taste and quality of the tobacco.

[0069] In this regard, refer to Figure 7 This embodiment also provides a temperature control method for a chimney structure. The temperature control method for a chimney structure is implemented through the above-mentioned chimney structure and includes the following steps.

[0070] S100: Turn on the heating element 2 at a preset power.

[0071] The preset power is the initial starting power of the heating element 2. Step S100 is generally in response to the user turning on the heating switch of the heated cigarette smoking device, at which time the heating element 2 is started with the preset power.

[0072] S200: Obtain the temperature of the cigarette 100.

[0073] The temperature of the cigarette 100 can be obtained by a temperature sensor disposed inside the accommodating chamber 11. Alternatively, the temperature of the gas inside the accommodating chamber 11 can be obtained by a temperature sensor to indirectly obtain the temperature of the cigarette 100. Alternatively, since the temperature of the cigarette 100 is positively correlated with the temperature of the heat conductor 3, the temperature of the heat conductor 3 can be obtained, and the temperature of the cigarette 100 can be obtained based on the mapping relationship between the temperature of the heat conductor 3 and the temperature of the cigarette 100, wherein the mapping relationship between the temperature of the heat conductor 3 and the temperature of the cigarette 100 can be a relationship diagram or a relationship table, which is obtained through a large number of experiments in the early stage and stored in the controller.

[0074] S300: Compare the temperature of the cigarette 100 with the upper limit of the temperature threshold.

[0075] The upper limit of the temperature threshold is the maximum temperature allowed for cigarette 100 to produce smoke normally.

[0076] If the temperature of the cigarette 100 is greater than the upper temperature threshold, step S310 is executed; if the temperature of the cigarette 100 is not greater than the upper temperature threshold, step S400 is executed.

[0077] S310: Reduce the power of the heating element 2.

[0078] If the temperature of the cigarette 100 is greater than the upper limit of the temperature threshold, it indicates that the temperature of the cigarette 100 is too high, which may be caused by the user not smoking the cigarette 100 for a long time. At this time, the power of the heating element 2 is reduced to reduce the temperature of the cigarette 100 to avoid affecting the taste and quality of the tobacco due to overheating of the cigarette 100.

[0079] Optionally, after executing step S310, the process returns to step S200, that is, the temperature of the cigarette 100 is acquired again, and corresponding steps are executed when the temperature of the cigarette 100 changes.

[0080] In this embodiment, a fan is also provided in the air flow channel 12, and the fan is used to blow external air into the accommodating chamber 11. By providing the fan, gas can be provided to the accommodating chamber 11, which is convenient for the user to inhale. At the same time, since the external air temperature is relatively low, increasing the amount of gas blown in can also reduce the gas temperature in the accommodating chamber 11.

[0081] Optionally, the method for controlling the temperature of the cigarette holder structure further includes step S320 executed synchronously with step S310.

[0082] S320: Increase the fan speed.

[0083] Increasing the speed of the fan can increase the amount of external air entering the airflow channel 12 and the accommodating chamber 11 , thereby reducing the temperature of the air in the accommodating chamber 11 , thereby reducing the temperature of the cigarette 100 .

[0084] Optionally, after executing step S320, the process returns to step S200, that is, the temperature of the cigarette 100 is acquired again, and corresponding steps are executed when the temperature of the cigarette 100 changes.

[0085] S400: Compare the temperature of the cigarette 100 with the lower limit of the temperature threshold.

[0086] The lower limit of the temperature threshold is the lowest temperature allowed for the cigarette 100 to normally produce smoke. If the temperature of the cigarette 100 is not greater than the upper limit of the temperature threshold, it indicates that the temperature of the cigarette 100 is not too high. However, considering that the user has just turned on the heating element 2, or the ambient temperature is low, resulting in a low initial temperature of the cigarette 100, the temperature of the cigarette 100 may rise slowly, and the initial amount of smoke may be low, which will also affect the actual experience of the user. Therefore, it is necessary to compare the temperature of the cigarette 100 with the lower limit of the temperature threshold to determine whether its temperature is too low.

[0087] If the temperature of the cigarette 100 is less than the lower limit of the temperature threshold, execute step S410; if the temperature of the cigarette 100 is not less than the lower limit of the temperature threshold, it indicates that the temperature of the cigarette 100 is not greater than the upper limit of the temperature threshold, and is not less than the lower limit of the temperature threshold, and the temperature of the cigarette 100 is within the normal range. At this time, return to step S200, that is, re-acquire the temperature of the cigarette 100, and execute the corresponding steps when the temperature of the cigarette 100 changes.

[0088] S410: Increase the power of heating element 2.

[0089] If the temperature of the cigarette 100 is lower than the lower limit of the temperature threshold, it indicates that the temperature of the cigarette 100 is too low. At this time, the power of the heating element 2 is increased to increase the temperature of the cigarette 100 to avoid affecting the user's actual experience due to the low temperature of the cigarette 100.

[0090] Optionally, after executing step S410, the process returns to step S200, that is, the temperature of the cigarette 100 is acquired again, and corresponding steps are executed when the temperature of the cigarette 100 changes.

[0091] Optionally, the method for controlling the temperature of the cigarette holder structure further includes step S420 executed synchronously with step S410.

[0092] S420: Reduce the fan speed.

[0093] Lowering the speed of the fan can reduce the amount of external air entering the airflow channel 12 and the accommodating chamber 11, and reduce the gas circulation in the accommodating chamber 11. The heating element 2 continues to heat the cigarette 100, which can increase the gas temperature in the accommodating chamber 11 and increase the temperature of the cigarette 100.

[0094] Optionally, after executing step S420, the process returns to step S200, that is, the temperature of the cigarette 100 is acquired again, and corresponding steps are executed when the temperature of the cigarette 100 changes.

[0095] The present embodiment also provides a heated cigarette smoking device, including the above-mentioned cigarette lifting tube structure, and also includes a smoking device shell and a power supply. The power supply and the cigarette lifting tube body 1 are both arranged in the smoking device shell. The power supply is used to supply power to the heating element 2 so that the heating element 2 generates heat. The cigarette lifting tube structure can heat the cigarette 100 through the heating element 2, and can also heat the heat conductor 3, thereby preheating the gas entering the accommodating chamber 11 through the air flow channel 12. The heated gas enters the accommodating chamber 11 and uniformly heats the cigarette 100. In addition, by providing a heat conductor 3 connected to the heating element 2, the heating of the cigarette 100 and the preheating of the gas can be achieved simultaneously through only one heating source. The structure is simple and the cost is low, thereby simplifying the overall structure and production cost of the heated cigarette smoking device.
