Description

Technical Field

[0001] The present application relates to the field of tobacco technology, and in particular to a heating element and a heating smoking device. Background Art

[0002] Currently, heated tobacco devices mainly use needle-type heating elements that are inserted into the cigarette for heating. The heating starts from the center of the cigarette and heats toward the periphery. In this inner core heating form, the heat is concentrated inside the tobacco, resulting in insufficient baking of the outer tobacco. In addition, since the heated inner core is in direct contact with the tobacco material, it is easy to stick together after heating, resulting in the carbonized tobacco scale easily falling into the heating device when the cigarette is pulled out.

[0003] At present, the industry also adopts the method of setting the heat source at the lower end of the cigarette. When the user draws, the external air flows through the heat source, and the heat source first heats the air. Then the hot air enters the cigarette, and the hot air heats the tobacco material to release smoke. This is the air heating technology. However, since there is no suction action in the preheating stage of air-heating smoking utensils, less hot air flows through the cigarette, resulting in insufficient preheating of the cigarette, insufficient atomization of the tobacco in the first two puffs, and insufficient smoke volume. Therefore, most of the currently designed air heating utensils adopt the form of peripheral auxiliary heating + air heating. In addition to the air heating element set at the end of the cigarette, the heating element is also set to wrap the tobacco segment. However, wrapping the heating element around the cigarette for heating makes it difficult to avoid the heating of the cigarette paper by the heating element, resulting in residual paper smell in the smoke.

[0004] Therefore, how to provide and design an air heating element that is convenient for taking out cigarettes and provides a good smoking experience is an urgent problem to be solved by technicians in the field of air heating. Utility Model Content

[0029] like Figures 1 to 3 As shown, the embodiment of the utility model provides a heating element for heating a cigarette inserted into a heated smoking device, comprising a heating inner core 1 and an airflow heating element 2. In this embodiment, the heating inner core 1 and the airflow heating element 2 are independent elements, and the heating inner core 1 is fixed to the middle of the airflow heating element 2. Of course, in other embodiments, the heating inner core 1 and the airflow heating element 2 may also be an integrated structure.

[0030] In this embodiment, the airflow heating element 2 is used to be arranged between the airflow channel of the heating tobacco device and the cigarette, and is made of high thermal conductivity and high heat capacity materials, such as aluminum oxide, zirconium oxide, graphite, etc. The airflow heating element 2 is in the shape of a round cake, and a fixing hole (unnumbered) is provided in the middle, so that the heating core 1 is tightly embedded in the fixing hole to fix the heating core 1 on the airflow heating element 2. In this embodiment, the fixing hole is a through hole, so that the heating core 1 runs through the entire airflow heating element 2 longitudinally, so that the heating is fast. A plurality of air-permeable through holes 21 are provided around the airflow heating element 2 to connect the airflow channel and the cigarette, and each air-permeable through hole 21 is respectively arranged around the heating core 1 and arranged in a honeycomb shape. This arrangement can make the air heating more sufficient and uniform.

[0031] In this embodiment, the heating inner core 1 is located in the middle of the airflow heating element 2, and is provided with an extension portion 11 extending out of the airflow heating element 2, and the extension portion 11 is used to insert into the tobacco of the cigarette to heat the tobacco. At the same time, after the heating inner core 1 is heated, it can transfer heat to the airflow heating element 2 to increase the temperature of the airflow heating element 2, so that the external air is heated and heated when it flows through the ventilation holes after inhalation, and then flows to the tobacco of the cigarette to heat the tobacco.

[0032] like Figure 4As shown, the embodiment of the utility model also provides a heating smoking device, including a body 3, a heating device (not shown) and the heating element as described above. The middle part of the body 3 is provided with a heating cavity 31 with an opening at one end for inserting a cigarette, and the body 3 is also provided with an air flow channel 32 connecting the outside with the bottom of the heating cavity 31 (the air flow during inhalation is as shown in FIG. Figure 4 As shown by the arrow, the heating element is located at the bottom of the heating chamber 31 (i.e., between the airflow channel of the heating device and the cigarette), and the heating device is used to heat the heating core 1 in the heating element. The body can also be provided with a power supply and an electrical system under the heating chamber, which can adopt a common structure and will not be described here.

[0033] In this embodiment, the heating device adopts electromagnetic induction heating, including an alternating current generating mechanism and an inductor coil 4 wound around the outside of the heating chamber. The heating core 1 adopts electromagnetic induction heating material. The alternating current generating mechanism is connected to the inductor coil 4 to generate an alternating current passing through the inductor coil 4, thereby generating an alternating magnetic field in the heating chamber. The surface of the heating core 1 cuts the alternating magnetic lines of force to generate eddy current effect and hysteresis loss effect. Eddy current and hysteresis loss cause metal atoms and magnetic molecules to move irregularly at high speed. The atoms collide and rub against each other to generate heat energy, thereby causing the heating core 1 to heat up.

[0034] In other embodiments, the heating device may also adopt a resistive heating method, including a power supply mechanism and a heating circuit arranged on the surface of the heating core 1 or a resistive heating wire arranged inside the heating core 1. The heating circuit or the resistive heating wire is connected to the power supply mechanism, and the power supply mechanism outputs current to the heating circuit or the resistive heating wire to make the heating core 1 heat up.

[0035] Compared with the prior art, the heating element and the heating smoking device of this embodiment have the following advantages:

[0036] 1. By setting a heating inner core and an airflow heating element, the heating inner core can transfer heat to the airflow heating element after heating to increase the temperature of the airflow heating element, so that the external air is heated and heated when it flows through the ventilation holes after inhalation, and then flows to the tobacco in the cigarette to heat the tobacco, thereby increasing the smoke volume in the first two puffs, providing a better inhalation experience and uniform heating; and the heat is directly transferred to the inside of the tobacco through the heating inner core, thereby improving the heating effect, accelerating the heating rate of the tobacco section of the cigarette and increasing the smoke volume heated by the cigarette. Compared with the existing air heating technology, it makes up for the problem of insufficient smoke volume in the initial smoking of the cigarette, and provides a better inhalation experience;

[0037] 2. Due to the superposition of the heating effect of the airflow heating element, when the user starts to smoke, the flow rate and temperature of the hot airflow entering the cigarette gradually increase. At this time, the temperature of the heating core can be appropriately reduced, which is also more conducive to reducing the adhesion between the heating core and tobacco substances, making it easier to take out the cigarette completely after smoking.

[0038] 3. The length of the extended part of the heating core is controlled to be half or less than the length of the tobacco section. After the heating core heats the tobacco, the adhesion between the heating core and the tobacco will be greatly reduced, which is convenient for the user to take out the cigarette completely after smoking, and will not cause tobacco materials to fall into the heating chamber.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
