Description
Technical Field
[0001] The invention belongs to the technical field of tobacco, and in particular relates to a segmented air 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 heating methods of existing heated tobacco devices are mainly resistive and electromagnetic heating. The resistive heating method is divided into central heating and circumferential heating. Among them, central heating tobacco devices have high energy utilization, but they do not heat the cigarettes sufficiently. At the same time, there is the disadvantage that tobacco residues are easy to remain in the flue and are difficult to clean. Circumferential heating tobacco devices have improved utilization of cigarettes because heat radiates from the circumference to the center, but the heat loss is high, and the paper smell may be produced during the heating process, which has a bad experience for consumers.
[0003] Existing electromagnetic heating methods are mainly divided into built-in sensor core type and external sensor type. The built-in sensor core heating smoking utensils do not need to be cleaned, but have the disadvantages of low core utilization, difficulty in processing cigarettes with built-in heating plates, high processing costs and metal pollution. In addition to the problem of low core utilization, the external sensor heating smoking utensils also have the problem of cleaning the smoking utensils. Based on the above reasons, an airflow heating smoking utensils has emerged in the industry, which heats the air flowing through by installing a coil winding or a honeycomb ceramic heating element at the bottom of the cigarette cup to heat the cigarette. The airflow heating smoking utensils have the advantages of high core utilization for granular cigarettes and no need to clean the smoking utensils. For this reason, the present invention is proposed. Summary of the invention

The upper surface of the bottom plate 17 of the cigarette cup is a conical surface 1701. The advantage of this setting is that the vertex 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. After the preheating is completed, the consumer draws and drives the hot air stored in the arc groove 1501 on the side wall of the cigarette cup 15 to flow into the cigarette cup. At the bottom, the airflow temperature at the bottom of the cigarette cup is the highest, and the hot air flow enters the cigarette core section through the bottom of the cigarette, and the generated smoke is inhaled by the consumer into the mouth; at this time, the heat of the cigarette core section comes from two parts, one is the hot air directly flowing through the cigarette core section to heat the cigarette core, and the other is the hot air flow heated by the middle heating plate 1802 and the lower heating plate 1803 on the side wall of the cigarette cup 15 to conduct heat conduction from the circumference to the axis; this heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience; in order to better adapt to different types of cigarette core materials, the heating plate 18, the annular The heating strip 1702 is independently controlled; when a granular-type cigarette core is used, the heating temperature of the annular heating strip 1702 can be increased, and the heating temperature of the heating plate 18 can be appropriately reduced to increase the temperature of the airflow entering the bottom of the cigarette core, thereby improving the utilization rate of the cigarette core; when a thin-sheet-type cigarette core is used, the heating temperature of the annular heating strip 1702 can be appropriately reduced, and the heating temperature of the heating plate 18 can be increased to enhance the heat conduction from the circumference to the center of the cigarette core, thereby improving the utilization rate of the cigarette core; or,
[0020] The heating temperature is set; a heat-not-burn cigarette with a built-in sensor core is inserted into the cigarette cup 15 through the cigarette insertion hole 101, and the cigarette is radially positioned by the heating plate 18 in the arc groove 1501 of the cigarette cup 15, and the cigarette is directly in contact with the heating plate 18; the bottom of the cigarette is axially limited by the limiting ring 16, so that the cigarette core is at the same height as the upper heating plate 1801 and the middle heating plate 1802 in the axial position; the starter battery 5 is energized, and the upper tower electromagnetic coil 9 and the middle tower electromagnetic coil 10 generate an alternating magnetic field, so that the upper heating plate 1801 and the middle heating plate 1802 are heated up The cigarette is preheated; after the preheating is completed, the consumer draws and drives the hot air stored in the side wall of the cigarette cup to flow to the bottom of the cigarette cup 15.

[0021] Beneficial effects of the present invention:
[0022] The segmented air heating smoking device of the present invention can better adapt to the types of cigarette cores such as granular cigarette cores, thin-sheet cigarette cores, or sensor-built-in cigarette cores by segmented control of the heating plates distributed on the side walls of the cigarette cups. When the smoking device of the present invention is used, cold air enters from the side walls of the cigarette, enters from the bottom of the cigarette after being heated by the heating plates arranged on the side walls and the heating strips on the bottom plate of the cigarette cup, and is sucked out from the filter end; the air is heated step by step when it flows through the air flow channel, and cooperates with the annular heating strips on the bottom plate of the cigarette cup so that the air flow is heated to the highest temperature at the bottom of the cigarette cup. At the same time, the heating plates arranged on the side walls are in direct contact with the cigarette to conduct heat from the circumference to the center. The hot air flow generated by the heating plates cooperates with the vacuum insulation components to keep the cigarette in a preheated state. In this way, 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 cigarette core is fully released, thereby greatly increasing the utilization rate of the cigarette core. The condensate generated by the cigarette during the use of the smoking device will not come into contact with batteries, circuits, and electronic components, thereby improving the life of the smoking device.
[0023] The segmented air heating smoking device of the present invention uses a tower electromagnetic coil; the tower electromagnetic coil is divided into three parts by the first isolation plate 7 and the second isolation plate 8: an upper tower electromagnetic coil 9, a middle tower electromagnetic coil 10 and a lower tower electromagnetic coil 11; the heating plate 18 is also divided into three sections: an upper heating plate 1801, a middle heating plate 1802 and a lower heating plate 1803; the lengths of the upper heating plate 1801, the middle heating plate 1802 and the lower heating plate 1803 are respectively the same as the heights of the upper tower electromagnetic coil 9, the middle tower electromagnetic coil 10 and the lower tower electromagnetic coil 11; the density of the coil turns of the upper tower electromagnetic coil 9, the middle tower electromagnetic coil 10 and the lower tower electromagnetic coil 11 is the same or different, and the energy density at different heights is different, which 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 the upper position of the cigarette core to be insufficiently heated. The tower electromagnetic coil can be set so that the coil radius increases from small to large from top to bottom, and the number of coil turns decreases from dense to sparse from top to bottom, so that the energy density at the upper end of the tower electromagnetic coil is higher after power is turned on, making the temperature at the upper end of the heating plate 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 smoke core section, so as to enhance the utilization rate of the smoke core.

[0042] The method for using the segmented air heating smoking device of the present invention comprises the following steps, and is applied to a granular cigarette core or a sheet cigarette core to heat a non-combustion cigarette:
[0043] The heating temperature is set; a granular or sheet-type cigarette core is inserted into the cigarette cup 15 through the cigarette insertion hole 101, and the cigarette is radially positioned by the heating plate 18 in the arc groove 1501 of the cigarette cup 15, and the cigarette is in direct contact with the heating plate 18; the bottom of the cigarette is axially limited by the limiting ring 16, and the limiting ring 16 makes the distance between the bottom of the cigarette cup 15 and the upper end wall of the cigarette cup bottom plate 17 be 1mm-5mm; so that the cigarette core is in the same axial position as the middle heating plate 1802 and the lower heating plate 1803 Height; start the battery 5 and energize it, the middle tower electromagnetic coil 10 and the lower tower electromagnetic coil 11 generate an alternating magnetic field, so that the middle heating plate 1802 and the lower heating plate 1803 and the annular heating strip 1702 on the bottom plate 17 of the cigarette cup quickly heat up the air inside the cigarette cup to preheat the cigarette, and the upper surface of the bottom plate 17 of the cigarette cup is a conical surface 1701. The advantage of this setting is that the vertex 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; after the preheating is completed, the consumer draws and drives the stored in the arc groove 1501 on the side wall of the cigarette cup 15 The hot air flows to the bottom of the cigarette cup. At this time, the air flow temperature at the bottom of the cigarette cup is the highest. The hot air then enters the cigarette core section through the bottom of the cigarette, and the generated smoke is inhaled by the consumer into the mouth; at this time, the heat of the cigarette core section comes from two parts. One is the hot air directly flowing through the cigarette core section to heat the cigarette core, and the other is the hot air flow heated by the middle heating plate 1802 and the lower heating plate 1803 on the side wall of the cigarette cup 15 to conduct heat conduction from the circumference to the axis of the cigarette core; this heating method will increase the utilization rate of the cigarette core and enhance the consumer's smoking experience; in order to better adapt to different types of cigarette core materials, the heating plate can be 18. The annular heating strip 1702 is independently controlled. When a granular-type cigarette core is used, the heating temperature of the annular heating strip 1702 can be increased, and the heating temperature of the heating plate 18 can be appropriately reduced to increase the temperature of the airflow entering the bottom of the cigarette core, thereby improving the utilization rate of the cigarette core. When a sheet-type cigarette core is used, the heating temperature of the annular heating strip 1702 can be appropriately reduced, and the heating temperature of the heating plate 18 can be increased to enhance the heat conduction from the circumference to the center of the cigarette core, thereby improving the utilization rate of the cigarette core.

[0045] The heating temperature is set; a heat-not-burn cigarette with a built-in sensor core is inserted into the cigarette cup 15 through the cigarette insertion hole 101, and the cigarette is radially positioned by the heating plate 18 in the arc groove 1501 of the cigarette cup 15, and the cigarette is directly in contact with the heating plate 18; the bottom of the cigarette is axially limited by the limiting ring 16, so that the cigarette core is at the same height as the upper heating plate 1801 and the middle heating plate 1802 in the axial position; the starter battery 5 is energized, and the upper tower electromagnetic coil 9 and the middle tower electromagnetic coil 10 generate an alternating magnetic field, so that the upper heating plate 1801 and the middle heating plate 1802 are heated up The cigarette is preheated; after the preheating is completed, the consumer draws and drives the hot air stored in the side wall of the cigarette cup to flow to the bottom of the cigarette cup 15. At this time, the air flow temperature at the bottom of the cigarette cup 15 is relatively low, and the hot air flow enters the cigarette core section through the bottom of the cigarette, and the generated smoke is inhaled into the mouth by the consumer; at this time, the heat for heating the cigarette core section mainly comes from two parts, one is the alternating magnetic field heating the cigarette core The built-in sensor heats the cigarette core to perform central heating, and the other is the upper heating plate 1801 and the middle heating plate 1802 that are in direct contact with the cigarette conduct heat from the circumference to the axis of the cigarette core; this heating method will increase the utilization rate of the cigarette core and enhance the consumer's smoking experience.
[0046] The segmented air heating smoking device of the present invention can better adapt to the cigarettes with granular core, thin sheet core, or sensor built-in core, etc. by controlling the heating plate distributed on the side wall of the cigarette cup in three sections. When the smoking device of the present invention is used, cold air enters from the arc groove and rectangular groove on the side wall of the cigarette, enters from the bottom of the cigarette after being heated by the heating plate arranged on the side wall and the heating strip on the bottom plate of the cigarette cup, and is sucked out from the filter end; the air is heated step by step when flowing through the air flow channel, and the air flow is heated to the highest temperature at the bottom of the cigarette cup in conjunction with the annular heating strip on the bottom plate of the cigarette cup; at the same time, the heating plate arranged on the side wall is in direct contact with the cigarette to conduct heat from the circumference to the center, and the hot air flow generated by the heating plate 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. The condensate generated by the cigarette during the use of the smoking device will not contact the battery, circuit and electronic components, etc., which improves the life of the smoking device.
[0047] The segmented air heating smoking device of the present invention uses a tower electromagnetic coil; the tower electromagnetic coil is divided into three parts by the first isolation plate 7 and the second isolation plate 8: an upper tower electromagnetic coil 9, a middle tower electromagnetic coil 10 and a lower tower electromagnetic coil 11; the heating plate 18 is also divided into three sections: an upper heating plate 1801, a middle heating plate 1802 and a lower heating plate 1803; the lengths of the upper heating plate 1801, the middle heating plate 1802 and the lower heating plate 1803 are respectively the same as the heights of the upper tower electromagnetic coil 9, the middle tower electromagnetic coil 10 and the lower tower electromagnetic coil 11; the density of the coil turns of the upper tower electromagnetic coil 9, the middle tower electromagnetic coil 10 and the lower tower electromagnetic coil 11 is the same or different, and the energy density at different heights is different, which 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 the upper position of the cigarette core to be insufficiently heated. The tower electromagnetic coil can be set so that the coil radius increases from small to large from top to bottom, and the number of coil turns decreases from dense to sparse from top to bottom, so that the energy density at the upper end of the tower electromagnetic coil is higher after power is turned on, making the temperature at the upper end of the heating plate 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 smoke core section, so as to enhance the utilization rate of the smoke core.

[0049] The adjustment mode of the smoking device is to heat the middle and lower sections of the three-section heating plate 18 and the annular heating strip 1702; the heating temperature of the smoking device is set in advance; the consumer inserts the cigarette, and the heating plate (18) in the arc groove (1501) of the cigarette cup (15) radially positions the cigarette, and the cigarette is in direct contact with the heating plate 18; the bottom of the cigarette is axially limited by the limiting ring 16, and the limiting ring 16 makes the distance between the bottom of the cigarette cup 15 and the upper end wall of the cigarette cup bottom plate 17 be 1mm-5mm; the cigarette core is at the same height as the middle heating plate 1802 and the lower heating plate 1803 in the axial position; the starting battery 5 is powered on, and the middle tower type The electromagnetic coil 10 and the lower tower electromagnetic coil 11 generate an alternating magnetic field, so that the middle heating plate 1802 and the lower heating plate 1803 and the annular heating strip 1702 on the bottom plate 17 of the cigarette cup quickly heat up the air inside the cigarette cup to preheat the cigarette. The upper surface of the bottom plate 17 of the cigarette cup is a conical surface 1701. The advantage of this setting is that the vertex 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. After the preheating is completed, the consumer draws and drives the hot air stored in the side wall of the cigarette cup to flow to the bottom of the cigarette cup. At this time, the air flow temperature at the bottom of the cigarette cup is the highest, and the hot air flow enters the cigarette core section through the bottom of the cigarette and is sucked out by the filter section of the cigarette. At this time, the heat of 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 hot air heated by the middle heating plate 1802 and the lower heating plate 1803 on the side wall of the cigarette cup 15 conducts heat conduction from the circumference to the axis. This heating method will increase the utilization rate of the cigarette core and improve the consumer's smoking experience. In order to better adapt to different types of cigarette core materials, the heating plate 18 and the annular heating strip 1702 can be independently controlled; when adapting to cigarette core materials with higher porosity such as granular cigarette cores, the heating temperature of the annular heating strip 1702 can be increased, and the heating temperature of the heating plate 18 can be appropriately reduced to enhance the temperature of the airflow entering the bottom of the cigarette core, thereby improving the utilization rate of the cigarette core; when adapting to cigarette core materials with lower porosity and thin cigarette paper walls such as thin sheet cigarette cores, the heating temperature of the annular heating strip 1702 can be appropriately reduced, and the heating temperature of the heating plate 18 can be increased to enhance the heat conduction from the circumference to the center of the cigarette core, thereby improving the utilization rate of the cigarette core.
[0050] Example 2: A method for heating a cigarette without burning it using a susceptor-embedded cigarette core using the segmented air heating smoking device of the present invention:
[0051] When the type of cigarette core with built-in adaptor is used, this type of cigarette generally has a plug at the bottom of the cigarette core, which is not suitable for high-temperature airflow to enter from the bottom of the cigarette, so only the side wall heat conduction is used for heating. The adjustment mode of the smoking device is to heat the upper heating plate 1801 and the middle heating plate 1802 of the three-stage heating plate 18. Set the heating temperature of the smoking device in advance, insert the heated non-burning cigarette into the cigarette cup 15 from the cigarette insertion hole 101, and the heating plate 18 in the arc groove 1501 of the cigarette cup 15 radially positions the cigarette, and the bottom of the cigarette is axially limited by the limiting ring 16, so that the cigarette core is at the same height as the upper heating plate 1801 and the middle heating plate 1802 in the axial position. After starting the smoking device, the upper tower electromagnetic coil 9 and the middle tower electromagnetic coil 10 generate a high-frequency alternating magnetic field, so that the upper heating plate 1801 and the middle heating plate 1802 are heated and heated to preheat the cigarette. After the preheating is completed, the consumer draws and drives the hot air stored in the side wall of the cigarette cup 15 to flow to the bottom of the cigarette cup. At this time, the air flow temperature at the bottom of the cigarette cup is relatively low, and the hot air flow enters the cigarette core section through the bottom of the cigarette and is sucked out by the filter section of the cigarette. At this time, the heat for heating the cigarette core section mainly comes from two parts. One is the high-frequency alternating magnetic field heating of the built-in sensor of the cigarette core to heat the center of the cigarette core, and the other is the upper heating plate 1801 and the middle heating plate 1802 that are in direct contact with the cigarette to conduct heat conduction from the circumference to the axis of the cigarette core. This heating method will increase the utilization rate of the cigarette core and enhance the consumer's smoking experience.

Without departing from the basic principles of the present technology, equivalent modifications and changes made by those skilled in the art to the technology proposed by the present invention should be included in the scope of the claims of the present invention.
