Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of tobacco, and in particular relates to a multi-adaptive heat flow heating smoking device and application thereof. 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 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 electronic circuits 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 multi-adaptive heat flow heating smoking device. The utilization rate of the cigarette core of the smoking device of the invention 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.
[0006] The technical solution of the present invention is as follows:

[0008] The electromagnetic coil assembly comprises: a tower-shaped electromagnetic coil 7 with a radius gradually increasing from top to bottom, an upper coil mounting plate 3 at the upper part thereof, and a lower coil mounting plate 4 at the lower part thereof;
[0009] The vacuum insulation heating module comprises: a cigarette cup 10 and an insulation sleeve 8 on its periphery, a vacuum space is formed between the outer wall of the cigarette cup 10 and the inner wall of the insulation sleeve 8; a plurality of arc grooves 1001 are axially opened on the inner wall of the cigarette cup 10, and a rectangular groove 1002 is opened between two arc grooves 1001; a heating plate 14 is arranged in each arc groove 1001; one side of the heating plate 14 is an arc surface that fits the inner surface of the arc groove 1001, and the opposite side of the arc surface of the heating plate 14 is a plane that is lower than the groove plane of the arc groove 1001;
[0010] The electromagnetic coil assembly is sleeved on the periphery of the vacuum insulation heating module.
[0011] Preferably, the bottom of the cigarette cup 10 is a cigarette cup bottom plate 12 , the upper surface of the cigarette cup bottom plate 12 is a conical surface 1201 , and an annular heating strip 1202 is arranged on the conical surface 1201 .
[0012] Preferably, the cigarette cup bottom plate 12 is installed on the threaded base 9 , and a limiting ring 11 is formed between the cigarette cup bottom plate 12 and the cigarette cup 10 .
[0013] Preferably, the heating plate 14 and the annular heating strip 1202 are made of ferromagnetic materials; 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 exactly the same in size and shape as the cigarette cup 10; a battery 5 is arranged in 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 application of the multi-adaptive heat flow heating smoking device for heating non-burning cigarettes.
[0016] Preferably, the method for using the multi-adaptive heat flow heating smoking device comprises the following steps:
[0017] The heating temperature of the smoking device is set; a heat-not-burn cigarette is inserted into the cigarette cup 10 from the cigarette insertion hole 101, and the non-arc groove 1001 and the rectangular groove 1002 of the cigarette cup 10 radially position the cigarette, and the cigarette does not directly contact the heating plate 14; the bottom of the cigarette is axially limited by the limiting ring 11, and 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 bottom plate 12 of the cigarette cup; the purpose is to leave sufficient space for the bottom of the cigarette and the bottom of the cigarette cup, so that the airflow can smoothly pass from the side of the cigarette cup 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 quickly, and the air inside the cigarette cup 10 is heated to preheat the cigarette; 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 and the rectangular groove 1002 on the side wall of the cigarette cup 10 to flow to the bottom of the cigarette cup 10. At this time, the air flow temperature at the bottom of the cigarette cup 10 is the highest, and the hot air flow enters the cigarette core section of the cigarette through the bottom of the cigarette to heat it, and the generated smoke is inhaled into the mouth by the consumer.
[0018] Beneficial effects of the present invention:
[0019] The multi-adaptive heat flow heating smoking device of the present invention has a heating principle that cold air enters from the side wall of the cigarette, enters from the bottom of the cigarette after being heated by the heating plate 14 arranged on the side wall of the cigarette cup 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 annular heating strip 1202 on the bottom plate of the cigarette cup is used to heat the air flow to the highest temperature at the bottom of the cigarette cup. At the same time, the hot air flow on the side wall has a heat conduction effect from the circumference to the center of the cigarette, and the vacuum insulation component is used 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 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 hot air flow 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. 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 device will not come into contact with batteries, circuits, and electronic components, thereby increasing the life of the smoking device. The opposite surface of the arc surface of the heating plate 14 is a plane, which is lower than the groove plane of the arc groove 1001. The cigarette does not directly contact the heating plate 14. The advantage of this setting is to avoid excessive circumferential temperature of the cigarette, which affects the smoking taste. A certain distance, such as 1mm-5mm, is maintained between the limiting ring 11 and the upper end wall of the cigarette cup bottom plate 12. 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 12 is designed as a conical surface 1201. 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.
[0020] The multi-adaptive 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 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 part of the cigarette core to be insufficiently heated. 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.
