Description
Technical Field
[0001] The invention belongs to the technical field of tobacco, and in particular relates to a circumferential auxiliary heating 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 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 air flowing through the smoking device is heated 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 device has the advantages of high utilization of the cigarette core for granular cigarettes 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 heating 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 occurs when flowing through the core section, resulting in low core utilization. Therefore, bottom airflow heating smoking tools are only suitable for granular cigarettes, such as high-porosity cores, and have poor cigarette adaptability; at the same time, the condensate generated after the core section of the bottom airflow heating smoking tool is heated is easy to corrode the heating component, resulting in poor durability of the smoking tool.
[0004] The present invention is proposed for this purpose. Summary of the invention

[0015] The second aspect of the present invention discloses the use of the circumferential auxiliary hot air heating smoking device for heating non-combustion cigarettes.
[0016] Preferably, the method for using the circumferential auxiliary hot air to heat the smoking device comprises the following steps:
[0017] The heating temperature is set; a heat-not-burn cigarette is inserted into the cigarette cup 10 from the cigarette insertion hole 101, and the cigarette is radially positioned by the internal heating plate 1402 in the rectangular groove 1002 of the cigarette cup 10, while the outer periphery of the cigarette is not in direct contact with the external heating plate 1401 but in direct contact with the internal heating plate 1402; the bottom of the cigarette is axially limited by the limiting ring 11, so that there is a distance of 1mm-5mm between the bottom of the cigarette cup 10 and the upper end wall of the cigarette cup bottom plate 12; the starter battery 5 is energized, the tower electromagnetic coil 7 generates a high-frequency alternating magnetic field, the heating plate 14 and the annular heating strip 1202 heat up rapidly, and the internal heating plate 1402 preheats the cigarette circumference; after the preheating is completed, the consumer inhales, and cold air enters from the side wall of the cigarette, driving the hot air stored in the arc groove 1001 to flow to the bottom of the cigarette cup 10, and the hot air then enters the cigarette core section of the cigarette through the bottom of the cigarette for heating, and the generated smoke is inhaled into the mouth by the consumer.
[0018] Beneficial effects of the present invention:
[0019] In the circumferential auxiliary heating air heating smoking device of the present invention, an external heating plate 1401 is arranged in each arc-shaped groove 1001, and the plane of the external heating plate 1401 is lower than the groove plane of the arc-shaped groove 1001 and does not contact the cigarette; an internal heating plate 1402 is arranged in each rectangular groove 1002, and the inner wall surface of the internal heating plate 1402 is slightly higher than the groove plane of the rectangular groove 1002, and directly contacts the outer periphery of the cigarette. The heating principle of the smoking device of the present invention is that cold air enters from the side wall of the cigarette, passes through the external heating plate 1401 arranged on the side wall of the cigarette cup and the annular heating strip 1202 on the bottom plate of the cigarette cup, so that the airflow is heated to the highest temperature at the bottom of the cigarette cup. At the same time, the hot airflow on the side wall and the internal heating plate 1402 have a heat conduction effect on the cigarette from the circumference to the center, 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 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, and after heating, it enters from the bottom of the cigarette and is sucked out from the filter end, 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. The heat for heating the cigarette core section comes from two parts. One is that the hot air directly flowing through the cigarette core section heats the cigarette core, and the other is that the internal heating plate 1402 directly in contact with the outer periphery of the cigarette and the hot air flow heated by the external heating plate 1401 flowing through the side wall of the cigarette cup 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. This multi-dimensional heating method can enable the smoking device to better adapt to different types of cigarette core types, such as thin-sheet, granular, non-tobacco matrix and other types of cigarette cores. In order to better adapt to different types of cigarette core materials, the inner heating plate 1402, the outer heating plate 1401, and the annular heating strip 1202 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 1202 can be increased, and the heating temperatures of the inner heating plate 1402 and the outer heating plate 1401 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 such as thin-sheet cigarette cores and thin cigarette paper walls, the heating temperature of the annular heating strip 1202 can be appropriately reduced to enhance the heating temperature of the inner heating plate 1402 and the outer heating plate 1401 to enhance the heat conduction from the circumference of the cigarette core to the center, thereby improving the utilization rate of the cigarette core.
[0020] In the circumferential auxiliary heating air heating smoking device of the present invention, cold air enters from the side wall of the cigarette, enters from the bottom of the cigarette after being heated by the external heating sheet 1401 arranged on the side wall and the annular heating strip 1202 on the bottom plate of the cigarette cup, and is sucked out from the filter end. The cold 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 cooperation with the annular heating strip 1202 on the bottom plate of the cigarette cup. At the same time, the internal heating sheet 1402 arranged on the side wall directly contacts the cigarette to conduct heat conduction from the circumference to the center for auxiliary heating. The hot air flow generated by the external heating sheet 1401 cooperates with the vacuum insulation component to keep the cigarette in a preheating 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.
[0021] The circumferential auxiliary hot air 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 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 upper end of the tower electromagnetic coil is higher after power is turned on, so that the temperature at the upper end of the heating plate 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.

[0040] The method for using the circumferential auxiliary hot air heating smoking device of the present invention to heat non-burning cigarettes comprises the following steps:
[0041] The heating temperature is set; a heat-not-burn cigarette is inserted into the cigarette cup 10 from the cigarette insertion hole 101, and the cigarette is radially positioned by the inner heating plate 1402 in the rectangular groove 1002 of the cigarette cup 10, and the outer periphery of the cigarette is not in direct contact with the outer heating plate 1401, but in direct contact with the inner heating plate 1402; the bottom of the cigarette is axially limited by the limiting ring 11, and there is a distance of 1mm-5mm between the bottom of the cigarette cup 10 and the upper end wall of the cigarette cup bottom plate 12; the starting battery 5 is energized, the tower electromagnetic coil 7 generates a high-frequency alternating magnetic field, the heating plate 14 and the annular heating strip 1202 heat up rapidly, and the inner heating plate 1402 preheats the cigarette circumference; after the preheating is completed, the consumer takes a puff, and cold air enters from the side wall of the cigarette, driving the hot air stored in the arc groove 1001 to flow to the bottom of the cigarette cup 10, and the hot air then enters the cigarette core section of the cigarette through the bottom of the cigarette for heating, and the generated smoke is inhaled into the mouth by the consumer.
[0042] In the circumferential auxiliary heating air heating smoking device of the present invention, an external heating plate 1401 is arranged in each arc groove 1001, and the plane of the external heating plate 1401 is lower than the groove plane of the arc groove 1001, and does not contact the cigarette; an internal heating plate 1402 is arranged in each rectangular groove 1002, and the inner wall surface of the internal heating plate 1402 is slightly higher than the groove plane of the rectangular groove 1002, and directly contacts the outer periphery of the cigarette. The heating principle of the smoking device of the present invention is that cold air enters from the side wall of the cigarette, and after being heated by the external heating plate 1401 arranged on the side wall of the cigarette cup and the annular heating strip 1202 on the bottom plate of the cigarette cup, enters from the bottom of the cigarette, and is sucked out from the filter end; at the same time, the internal heating plate 1402 preheats the cigarette circumference to the center through heat conduction. The hot air flow generated by the external heating plate 1401 cooperates with the vacuum insulation component 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 the battery, circuit and electronic components, etc., which increases the life of the smoking device. The heat for heating the cigarette core section comes from two parts.

This multi-dimensional heating method can enable the smoking device to better adapt to different types of cigarette core types, such as thin slice type, granular type, non-tobacco matrix type and other types of cigarette cores. In order to better adapt to different types of cigarette core materials, the inner heating plate 1402, the outer heating plate 1401, and the annular heating strip 1202 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 1202 can be increased, and the heating temperatures of the inner heating plate 1402 and the outer heating plate 1401 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 adapting to cigarette core materials with lower porosity and thin cigarette paper walls such as sheet-type cigarette cores, the heating temperature of the annular heating strip 1202 can be appropriately reduced, and the heating temperatures of the inner heating plate 1402 and the outer heating plate 1401 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.
[0043] In the circumferential auxiliary heating air heating smoking device of the present invention, cold air enters from the side wall of the cigarette, enters from the bottom of the cigarette after being heated by the external heating sheet 1401 arranged on the side wall and the annular heating strip 1202 on the bottom plate of the cigarette cup, and is sucked out from the filter end. The cold 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 cooperation with the annular heating strip 1202 on the bottom plate of the cigarette cup. At the same time, the internal heating sheet 1402 arranged on the side wall directly contacts the cigarette to conduct heat conduction from the circumference to the center for auxiliary heating. The hot air flow generated by the external heating sheet 1401 cooperates with the vacuum insulation component to keep the cigarette in a preheating 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.
[0044] The circumferential auxiliary heat air heating smoking device of the present invention uses a tower-type electromagnetic coil; the energy density of the tower-type electromagnetic coil is different at different heights, and can be set according to actual conditions to improve the utilization rate of the cigarette core.
