Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of tobacco, and in particular relates to a heat flow heating smoking device and its application. Background Art
[0002] As consumers' health awareness increases, the demand for alternatives to traditional cigarettes increases. As a relatively harmless tobacco product, the market size of heated cigarettes continues to expand. The existing heating methods of heated tobacco sets are mainly resistive and electromagnetic heating. The resistive heating method is divided into central heating and circumferential heating. Among them, the central heating type has a high energy utilization rate, but the heating of the cigarette is not sufficient. At the same time, there is a disadvantage that tobacco residues are easy to remain in the flue and are difficult to clean. The circumferential heating type of tobacco sets radiates heat from the circumference to the center, which improves the utilization rate of cigarettes, but the heat loss is high, and the paper smell may be produced during the heating process, which has a bad experience for consumers. The existing electromagnetic heating methods are mainly divided into sensor core built-in type and sensor external type. The sensor core built-in heating tobacco set does not need to clean the tobacco set, but it has the disadvantages of low core utilization, difficulty in processing the heating plate built-in cigarette, high processing cost and metal pollution; in addition to the problem of low core utilization, the external sensor heating tobacco set also has the problem of cleaning the tobacco set. Based on the above reasons, an airflow heating smoking device has emerged in the industry. The airflow heating method heats the cigarette by installing a coil winding or a honeycomb ceramic heating element at the bottom of the cigarette cup to heat the air flowing through it. The airflow heating method has the advantages of high utilization of the cigarette core and no need to clean the smoking device.
[0003] The heating principle of existing airflow heating smoking tools is that cold air flows through the heating component at the bottom of the cigarette cup and is heated, then enters the heated cigarette core section from the bottom of the cigarette, and then flows out from the filter rod section. The disadvantage is that a large temperature drop will occur when flowing through the cigarette core section, resulting in low cigarette core utilization; bottom airflow heating smoking tools are only suitable for granular cigarettes, such as cigarette cores with high porosity, and have poor cigarette adaptability; at the same time, the condensate generated after the cigarette core section of the bottom airflow heating smoking tool is heated is easy to corrode the circuit and electronic components, resulting in poor durability of the smoking tool.
[0004] The present invention is proposed for this purpose. Summary of the invention
[0005] The invention discloses a heat flow heating smoking device. By using the smoking device of the invention, the utilization rate of the cigarette core is increased; the condensate generated during the use of the smoking device will not contact the battery, circuit and electronic components, etc., thereby increasing the life of the smoking device.

[0010] The electromagnetic coil assembly is sleeved on the periphery of the vacuum insulation heating module.
[0011] Preferably, the bottom of the cigarette cup 9 is a cigarette cup bottom plate 11, and the upper surface of the cigarette cup bottom plate 11 is a conical surface 1101; the cigarette cup bottom plate 11 is installed on a threaded base 12, and the outer wall of the threaded base 12 has an external thread 120; there is a limiting ring 10 between the cigarette cup 9 and the cigarette cup bottom plate 11.
[0012] Preferably, the bottom of the inner wall of the heat insulating sleeve 8 is provided with an internal thread 802 , which is matched with the external thread 120 ; a plurality of trapezoidal openings 801 are provided on the side wall of the upper end of the heat insulating sleeve 8 ; the trapezoidal openings 801 are matched with the trapezoidal grooves 901 .
[0013] Preferably, the cigarette cup 9 and the cigarette cup bottom plate 11 are made of ferromagnetic materials with good magnetic permeability; the excitation frequency of the tower electromagnetic coil 7 is above 100 kHz. The material of the heat insulation sleeve 8 is preferably such that the tower electromagnetic coil 7 has no effect on it.
[0014] Preferably, the smoking device further comprises a smoking device shell assembly; the smoking device shell assembly comprises: a smoking device upper shell 1 and a smoking device lower shell 2, which are connected by a snap fastener; the smoking device upper shell 1 is arranged at the periphery of the electromagnetic coil assembly, and a cigarette insertion hole 101 is opened on its upper end wall, and the cigarette insertion hole 101 is adapted to the 9 mouths of the cigarette cup; a battery 5 is arranged inside the smoking device lower shell 2, and the battery 5 is installed on the inner wall of the smoking device lower shell 2 through a battery mounting plate 6.
[0015] The second aspect of the present invention discloses the use of the heat flow heating smoking device for heating non-combustion cigarettes.
[0016] Preferably, the method for using the heat flow heating smoking device comprises the following steps:
[0017] The heating temperature is set; the heat-not-burn cigarette is inserted into the cigarette cup 9 through the cigarette insertion hole 101, and the cigarette is radially positioned by the non-trapezoidal groove portion of the inner wall of the cigarette cup 9; the bottom of the cigarette is axially limited by the limiting ring 10, and the limiting ring 10 allows a distance of 1mm-5mm between the upper wall of the cigarette cup bottom plate 11 and the cigarette cup 9. The purpose of this setting is to leave sufficient space between the bottom of the cigarette and the upper wall of the cigarette cup bottom plate 11, so that the airflow can smoothly enter the bottom of the cigarette from the side wall of the cigarette cup; the starting battery 5 is energized, the tower electromagnetic coil 7 generates an alternating magnetic field, the cigarette cup 9 and the cigarette cup bottom plate 11 are heated, and the non-trapezoidal groove portion of the inner wall of the cigarette cup 9 has a heat conduction effect on the cigarette from the circumference to the center, and the vacuum insulation component is used to keep the cigarette in a preheated state. The air inside the cigarette cup 9 also preheats the cigarette, and the upper surface of the cigarette cup bottom plate 11 is a conical surface 1101. The advantage of this arrangement is that the top of the conical surface is closest to the bottom of the cigarette core, so the temperature at the center of the cigarette core is the highest. This heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. After preheating, the consumer's inhalation drives the hot air stored in the trapezoidal groove 901 on the side wall of the cigarette cup 9 to flow to the bottom plate 11 of the cigarette cup. At this time, the air flow temperature of the bottom plate 11 of the cigarette cup is the highest, and the hot air flow enters the cigarette core section through the bottom plate 11 of the cigarette cup and is sucked out by the filter section of the cigarette. At this time, the heat for heating the cigarette core section comes from two parts. One is that the hot air directly flows through the cigarette core section to heat the cigarette core, and the other is that the non-trapezoidal groove part of the inner wall of the cigarette cup 9 conducts heat from the circumference to the axis of the cigarette core. This heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. At the same time, this airflow heating method is suitable for a variety of cigarette core types such as granular, tobacco sheet, and non-tobacco matrix.
[0018] Beneficial effects of the present invention:
[0019] The heat flow heating smoking device of the present invention has a heating principle that cold air enters from the trapezoidal groove 901 of the smoking device, enters from the bottom of the cigarette after being heated by the side wall of the cigarette cup and the bottom plate 11 of the cigarette cup, and is sucked out from the filter end. The cold air is heated step by step when flowing through the airflow channel, and the conical surface 1101 on the upper surface of the bottom plate 11 of the cigarette cup is used to heat the airflow to the highest temperature at the bottom of the cigarette cup. At the same time, the non-trapezoidal groove part of the inner wall of the cigarette cup 9 has a heat conduction effect from the circumference to the center of the cigarette, and the vacuum insulation component is used to make the cigarette always in a preheating state. In this way, the temperature drop of the hot air flow from the bottom of the cigarette to the filter section is reduced, so that the aerosol of the entire section of the cigarette core is fully released, thereby greatly increasing the utilization rate of the cigarette core. The heat for heating the cigarette core section comes from two parts. One is that the hot air directly flows through the cigarette core section to heat the cigarette core, and the other is that the non-trapezoidal groove part of the inner wall of the cigarette cup 9 conducts heat from the circumference to the axis of the cigarette core; this heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. At the same time, this airflow heating method is suitable for various types of cigarette cores, such as granular, tobacco sheet, and non-tobacco matrix. The condensate generated by the cigarette during the use of the smoking utensil will not come into contact with batteries, circuits, and electronic components, thereby increasing the life of the smoking utensil. The limiting ring 10 allows a distance of 1mm-5mm between the upper wall of the cigarette cup bottom plate 11 and the cigarette cup 9. The purpose is to leave sufficient space between the bottom of the cigarette and the bottom of the cigarette cup, so that the airflow can smoothly enter the bottom of the cigarette from the side wall of the cigarette cup. The upper surface of the cigarette cup bottom plate 11 is designed as a conical surface 1101. The advantage of this setting is that the top of the conical surface is closest to the bottom of the cigarette core, so the temperature at the center of the cigarette core is the highest.
[0020] The heat flow heating smoking device of the present invention uses a tower electromagnetic coil whose radius gradually increases from top to bottom; the energy density of the tower electromagnetic coil is different at different heights, and can be set according to actual conditions to improve the utilization rate of the cigarette core. Taking the thin-sheet type cigarette core material as an example, because the texture of the thin-sheet type cigarette core is relatively dense, when the heated heat flow enters from the bottom of the cigarette core, the temperature drop is large, which will cause insufficient heating of the upper part of the cigarette core. The tower electromagnetic coil can be set so that the coil radius changes from small to large from top to bottom, and the number of coil turns changes from dense to sparse from top to bottom, so that the energy density of the tower electromagnetic coil at the upper end is higher after power is turned on, so that the temperature at the upper end of the inner wall of the cigarette cup is higher. When the smoking device heats the cigarette, the heat generated at the upper end of the heating plate has a stronger heat conduction effect on the cigarette core section, so as to enhance the utilization rate of the cigarette core.
[0021] The heat flow heating smoking device of the present invention, the cigarette cup, the limiting ring, and the bottom plate of the cigarette cup together form a heating whole, the structure is simple, and an air flow channel is reserved. The inner wall of the cigarette cup 9 is evenly opened with a number of trapezoidal grooves 901 in the axial direction. This arrangement has two functions, one is to ensure the air flow channel; the other is to reduce the contact between the cigarette and the cigarette cup, and prevent excessive heating of the cigarette paper from causing bad odor; cold air enters from the trapezoidal groove 901 on the side wall of the cigarette cup, and is heated step by step when flowing through the air flow channel, so that the air flow is heated to the highest temperature at the upper end surface of the bottom of the cigarette cup; at the same time, the hot air flow in the trapezoidal groove 901 cooperates with the vacuum insulation component to keep the cigarette in a preheating state, so that the temperature drop of the hot air flow is reduced in the process of flowing from the bottom of the cigarette to the filter section, so that the aerosol of the entire section of the cigarette core is fully released, thereby greatly increasing the utilization rate of the cigarette core.
[0022] The heat flow heating smoking device of the present invention uses a tower electromagnetic coil. The energy density of the tower electromagnetic coil is different at different heights, and the utilization rate of the cigarette core can be improved according to actual conditions. Taking the particle type cigarette core material as an example, because the texture of the particle type cigarette core is relatively loose, the temperature drop is small when the heated heat flow enters from the bottom of the cigarette core. In this way, the temperature at the bottom of the cigarette cup is increased as much as possible, and energy consumption can be reduced under the premise of ensuring the utilization rate of the cigarette core. The tower electromagnetic coil is set so that the coil radius changes from large to small from top to bottom, and the number of coil turns changes from sparse to dense from top to bottom. In this way, the energy density of the tower electromagnetic coil near the lower end is higher after power is turned on, so that the temperature at the lower end of the cigarette cup is higher. The shape of the magnetic coil can also be cylindrical, U-shaped, etc., as long as similar functions are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The method for using the heat flow heating smoking device of the present invention for heating non-combustion cigarettes comprises the following steps:
[0039] The heating temperature is set; the heat-not-burn cigarette is inserted into the cigarette cup 9 through the cigarette insertion hole 101, and the cigarette is radially positioned by the non-trapezoidal groove portion of the inner wall of the cigarette cup 9; the bottom of the cigarette is axially limited by the limiting ring 10, and the limiting ring 10 allows a distance of 1mm-5mm between the upper wall of the cigarette cup bottom plate 11 and the cigarette cup 9. The purpose of this setting is to leave sufficient space between the bottom of the cigarette and the upper wall of the cigarette cup bottom plate 11, so that the airflow can smoothly enter the bottom of the cigarette from the side wall of the cigarette cup; the starting battery 5 is energized, the tower electromagnetic coil 7 generates an alternating magnetic field, the cigarette cup 9 and the cigarette cup bottom plate 11 are heated, and the non-trapezoidal groove portion of the inner wall of the cigarette cup 9 has a heat conduction effect on the cigarette from the circumference to the center, and the vacuum insulation component is used to keep the cigarette in a preheated state. The air inside the cigarette cup 9 also preheats the cigarette, and the upper surface of the cigarette cup bottom plate 11 is a conical surface 1101. The advantage of this arrangement is that the top of the conical surface is closest to the bottom of the cigarette core, so the temperature at the center of the cigarette core is the highest. This heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. After preheating, the consumer's inhalation drives the hot air stored in the trapezoidal groove 901 on the side wall of the cigarette cup 9 to flow to the bottom plate 11 of the cigarette cup. At this time, the air flow temperature of the bottom plate 11 of the cigarette cup is the highest, and the hot air flow enters the cigarette core section through the bottom plate 11 of the cigarette cup and is sucked out by the filter section of the cigarette. At this time, the heat for heating the cigarette core section comes from two parts. One is that the hot air directly flows through the cigarette core section to heat the cigarette core, and the other is that the non-trapezoidal groove part of the inner wall of the cigarette cup 9 conducts heat from the circumference to the axis of the cigarette core. This heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. At the same time, this airflow heating method is suitable for a variety of cigarette core types such as granular, tobacco sheet, and non-tobacco matrix.
[0040] The heat flow heating smoking device of the present invention has a heating principle that cold air enters from the trapezoidal groove 901 of the smoking device, enters from the bottom of the cigarette after being heated by the side wall of the cigarette cup and the bottom plate 11 of the cigarette cup, and is sucked out from the filter end. The cold air is heated step by step when flowing through the airflow channel, and the conical surface 1101 on the upper surface of the bottom plate 11 of the cigarette cup is used to heat the airflow to the highest temperature at the bottom of the cigarette cup. At the same time, the non-trapezoidal groove part of the inner wall of the cigarette cup 9 has a heat conduction effect from the circumference to the center of the cigarette, and the vacuum insulation component is used to make the cigarette always in a preheating state.

At the same time, this airflow heating method is suitable for various types of cigarette cores, such as granular, tobacco flake, and non-tobacco matrix. The condensate generated by the cigarette during use will not come into contact with the heating component, which increases the life of the cigarette. The limiting ring 10 allows a distance of 1mm-5mm between the upper wall of the cigarette cup bottom plate 11 and the cigarette cup 9. The purpose is to leave sufficient space between the bottom of the cigarette and the bottom of the cigarette cup, so that the airflow can smoothly enter the bottom of the cigarette from the side wall of the cigarette cup. The upper surface of the cigarette cup bottom plate 11 is designed as a conical surface 1101. The advantage of this setting is that the top of the conical surface is closest to the bottom of the cigarette core, so the temperature at the center of the cigarette core is the highest.
[0041] The heat flow heating smoking device of the present invention uses a tower electromagnetic coil whose radius gradually increases from top to bottom; the energy density of the tower electromagnetic coil is different at different heights, and can be set according to actual conditions to improve the utilization rate of the cigarette core.

When the smoking device heats the cigarette, the heat generated at the upper end of the heating plate has a stronger heat conduction effect on the cigarette core section, so as to enhance the utilization rate of the cigarette core.
[0042] The heat flow heating smoking device of the present invention, the cigarette cup, the limiting ring, and the bottom plate of the cigarette cup together form a heating whole, the structure is simple, and an air flow channel is reserved. The inner wall of the cigarette cup 9 is evenly opened with a number of trapezoidal grooves 901 in the axial direction. This arrangement has two functions, one is to ensure the air flow channel; the other is to reduce the contact between the cigarette and the cigarette cup to prevent excessive heating of the cigarette paper from causing bad odor.

The shape of the magnetic coil can also be cylindrical, U-shaped, etc., as long as similar functions are achieved.
[0044] The heat flow heating smoking device of the present invention can also adopt resistance heating. The purpose of heating the cigarette can be achieved by selecting materials with higher thermal conductivity to process the cigarette cup and the bottom plate of the cigarette cup and directly heating the cigarette cup and the bottom plate of the cigarette cup by electricity.
