Description

Technical Field

[0001] The present invention relates to the technical field of cigarette heating,

[0002] In particular, the present invention relates to a structure for uniform heating of cigarettes that enhances air flow disturbance. Background Art

[0003] With the increasing development of cigarette production technology, the types and appearances of cigarettes are more diversified, and cigarettes with unique shapes are more likely to be favored by people. Therefore, it is necessary to heat the cigarette sticks. Due to the high heating efficiency of electromagnetic heating technology, many tobacco companies have begun to apply electromagnetic heating technology in the field of low-temperature heating of cigarettes.

[0004] A common technical solution is to set an induction coil in the smoking device, and adjust the magnetic field strength by adjusting the density, cross-sectional shape and size, number of turns, etc. of the coil arrangement, or to achieve different heating functions through different structures or different materials of the susceptor. For example, Chinese Patent Invention Patent CN104095293A discloses an electromagnetic heating type suction device for heating non-combustible cigarettes, including an end cap, a heater and an electromagnetic induction system. The heater has a heating cavity for accommodating and placing non-combustible cigarettes. The end cap is detachably and combinably connected to the suction end of the heater; a filter tip is provided on the end cap, and the filter tip is in communication with the inner cavity of the heating cavity. The end cap has a round cap, and a plurality of air inlet holes are provided on the round cap, and the air inlet holes are in communication with the inner cavity of the heating cavity; the electromagnetic induction system includes a temperature control circuit and an induction coil electrically connected to the temperature control circuit, and the induction coil is spirally wound around the outside of the heating cavity. The above invention heats the inner liner heating element by means of electromagnetic heating of the electromagnetic induction system, and heats the tobacco product by the inner liner, which can improve the heating speed and has high thermal efficiency, fast heating speed, can achieve instantaneous heating, and meets the needs of the suction taste. And the heating is uniform, so that the tobacco product can be fully heated, preventing waste caused by insufficient heating of the tobacco product.

[0005] However, the above heating device has great defects: 1. The central heating method is adopted, and its heating needle only radiates a circle of tobacco shreds around the heating needle. The tobacco shreds near the heating needle are heated sufficiently and can release enough tobacco emissions. Among them, the outer tobacco shreds cannot fully release tobacco emissions because they do not obtain enough heat. 2. The heating needle adopted needs to be completely attached to the tobacco shreds to fully heat the tobacco shreds. The maximum heating temperature of the heating needle can reach 320 °C. After the heated flue gas passes through the filter section, there may be a problem of too high inlet temperature.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient structure for uniform heating of cigarettes that enhances air flow disturbance. Summary of the Invention

[0007] The object of the present invention is to provide a cigarette uniform heating structure with enhanced air flow disturbance, which has a simple structure. By generating an air flow inside the heated cigarette and making it flow to the peripheral tobacco part after being heated, the high-temperature air flow is transmitted to the peripheral tobacco part, so that the heated tobacco is uniformly heated. At the same time, external cold air flows in, effectively alleviating the problem of high inlet temperature.

[0008] To achieve the above object, the present invention is realized by adopting the following technical solutions:

[0009] A cigarette uniform heating structure with enhanced air flow disturbance includes a cigarette rod and a smoking device. The cigarette rod includes a suction section and a heating section. A plurality of cavity balls are arranged inside the end of the heating section far away from the suction section. The smoking device is provided with a heating cavity for conveniently inserting the cigarette rod. A heating needle is arranged in the heating cavity. When the cigarette rod is inserted into the heating cavity, the heating needle is inserted into the heating section, and the cavity balls are uniformly arranged around the heating needle. The cavity ball includes a cavity ball wall and an inner cavity covered by the cavity ball wall. A through hole for communicating with the heating cavity is arranged on the side wall of the smoking device.

[0010] As a preference of the present invention, the cavity ball wall is a heat-melting component.

[0011] As a preference of the present invention, a non-combustible and non-toxic gas after high-pressure treatment is arranged in the inner cavity.

[0012] As a preference of the present invention, a gas flow valve is arranged in the through hole, so that the gas outside the smoking device flows into the heating cavity unidirectionally.

[0013] As a preference of the present invention, the heating needle is a sensor, and an electromagnetic coil is arranged on the inner side wall of the heating cavity.

[0014] As a preference of the present invention, a power supply for supplying power to the electromagnetic coil and a control module for controlling the operation of the power supply are arranged in the smoking device.

[0015] As a preference of the present invention, a cooling section is arranged between the suction section and the heating section.

[0016] The present invention also provides a uniform heating method for a cigarette uniform heating structure with enhanced air flow disturbance, including the following steps:

[0017] S1: Add a plurality of cavity balls into the heating section of the cigarette rod;

[0018] S2: Insert the cigarette rod into the heating cavity, so that the heating needle in the heating cavity is inserted into the heating section of the cigarette rod;

[0019] S3: Start the heating needle to work to heat the heating section of the cigarette rod, and at the same time heat the cavity balls surrounding the heating needle;

[0020] S4: The high temperature generated by the working of the heating needle destroys the structure of the cavity ball wall, causing the heated gas in the inner cavity of the cavity ball wall to expand and release;

[0021] S5: The heated gas flows towards the peripheral tobacco shreds, heating the peripheral tobacco shreds far from the heating needle and releasing tobacco release substances;

[0022] S6: Gas flows into the heating cavity through the through holes on the side wall of the smoking device to supplement and mix with the heated flue gas in the heating cavity, thereby reducing the temperature of the flue gas entering the suction section.

[0023] As a preference of the present invention, when performing step S4, the cavity ball wall melts after being heated by the heating needle, releasing the non-combustible and non-toxic gas under high pressure and heat in the inner cavity.

[0024] As a preference of the present invention, when performing step S6, the gas flow valve in the through holes on the side wall of the smoking device allows the gas outside the smoking device to flow unidirectionally into the heating cavity.

[0025] The beneficial effect of a cigarette uniform heating structure with enhanced air flow disturbance of the present invention lies in: simple structure, generating air flow inside the heated cigarette and flowing to the peripheral tobacco shreds part after being heated, so that the high-temperature air flow is transmitted to the peripheral tobacco shreds part, making the heated tobacco shreds evenly heated, and at the same time allowing external cold air to flow in, effectively alleviating the problem of high inlet temperature.

Detailed Embodiments

[0030] The following are specific embodiments of the present invention, further describing the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements and steps of the modules and steps set forth in these embodiments do not limit the scope of the present invention.

[0032] Meanwhile, it should be understood that for the sake of convenience in description, the processes in the accompanying drawings do not solely proceed individually, but multiple steps are carried out crosswise with each other.

[0033] The following description of at least one exemplary embodiment is actually merely illustrative and in no way restricts the present invention and its application or use.

[0034] Technologies, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be regarded as part of the authorization specification.

[0035] Embodiment 1: As Figure 1 、 2 shown, it is merely one of the embodiments of the present invention. A cigarette uniform heating structure for enhancing air flow disturbance includes a cigarette rod 1 and a smoking device 2. The cigarette rod 1 includes a suction section 11 and a heating section 12. Inside the end of the heating section 12 away from the suction section 11, several cavity balls 13 are provided. On the smoking device 2, a heating cavity 21 for facilitating the insertion of the cigarette rod 1 is provided. Inside the heating cavity 21, a heating needle 22 is provided. When the cigarette rod 1 is inserted into the heating cavity 21, the heating needle 22 is inserted into the heating section 12 and the cavity balls 13 are evenly arranged around the heating needle 22. The cavity ball 13 includes a cavity ball wall 131 and an inner cavity 132 covered within the cavity ball wall 131. A through hole 23 for communicating with the heating cavity 21 is provided on the side wall of the smoking device 2.

[0036] In the present invention, the cigarette rod 1 includes a suction section 11 and a heating section 12. The heating section 12 is for being inserted into the heating cavity 21 of the smoking device 2 and being heated by the heating needle 22. The suction section 11 is the filter tip part. The smoker holds the suction section 11 and inhales the tobacco release released by the heating of the heating section 12 by the heating needle 22.

[0037] Here, in addition to the conventionally arranged tobacco shreds in the heating section 12, a lot of cavity balls 13, that is, hollow spherical objects, are added to the tobacco shreds. The cavity ball 13 includes a cavity ball wall 131 and an inner cavity 132. When the heating needle 22 is inserted into the heating section 12, the heating needle 22 not only heats the tobacco shreds but also heats the cavity balls 13. The high temperature will damage the cavity ball wall 131 of the cavity balls 13 and also cause the inner cavity 132 to expand due to heat. After reaching the critical point of the destruction of the cavity ball wall 131, the cavity ball wall 131 is damaged and the gas in the inner cavity 132 explodes, causing air flow disturbance in the heating cavity 21.

[0038] Of course, multiple cavity balls 13 should be evenly arranged near the axis of the heating section 12. Note that they should not be directly arranged at the axis, because the heating needle 22 may be inserted into the axis. This can prevent the cavity ball 13 from being damaged when the heating needle 22 is inserted. That is, after the heating needle 22 is inserted to the axis position of the heating section 12, multiple cavity balls 13 should be evenly arranged around the heating needle 22.

[0039] Then, when the heating needle 22 starts to work, causing the cavity ball wall 131 to be destroyed and the gas in the inner cavity 132 to burst out, the gas flow direction in the entire heating cavity 21 is from the center of the heating section 12 to the periphery.

[0040] In this way, when the heating gas in the inner cavity 132 flows, the surrounding tobacco shreds will obtain heat, so that the middle and the surrounding of the heating section 12 are heated synchronously, and the cigarette is heated more evenly during the smoking and heating process.

[0041] It should be noted that, in the present embodiment, a through hole 23 for communicating with the heating chamber 21 is provided on the side wall of the smoking device 2. When the airflow in the heating chamber 21 is disturbed, the air outside the smoking device 2 will flow into the heating chamber 21 and mix with the heated smoke in the heating chamber 21, thereby reducing the temperature of the smoke that passes through the suction section 11 and reaches the mouth of the smoker when the smoker inhales, thereby alleviating the problem of overheating of the inlet smoke in heated cigarettes.

[0042] The gas flow direction in the heating chamber 21 and the gas flow direction at the through hole 23 are as follows: Figure 2 shown.

[0043] The structure of the cigarette uniform heating structure with enhanced airflow disturbance of the present invention is simple. Airflow is generated inside the heated cigarette and flows to the peripheral tobacco part under heat, so that the high-temperature airflow is transferred to the peripheral tobacco part, so that the heated tobacco is heated evenly, and external cold air flows in at the same time, effectively alleviating the problem of high inlet temperature.

[0044] Embodiment 2, still as Figure 1 , 2 The figure shown is only one of the embodiments of the present invention. On the basis of the first embodiment, in a uniform heating structure of a cigarette with enhanced airflow disturbance of the present invention, the cavity ball wall 131 is a heat-melting material. The cavity ball wall 131 can be made of gelatin or other gelatin-like materials so that it can melt when heated to a certain temperature (slightly lower than the temperature of 300 degrees Celsius generated by the heating needle 22).

[0045] Of course, the inner cavity 132 is provided with non-flammable and non-toxic gas after high-pressure treatment, that is, in a non-heated state, the pressure in the inner cavity 132 of the cavity ball 13 is also greater than the atmospheric pressure outside the cavity ball 13. When the cavity ball wall 131 is damaged by heat, the amount of gas exploded is larger and the airflow disturbance intensity is higher.

[0046] Here, the non-combustible and non-toxic gases include nitrogen, carbon dioxide, etc. Since carbon dioxide has good compressibility, carbon dioxide is generally preferred for high-pressure treatment and placed in the inner cavity 132.

[0047] In addition, the cavity balls 13 should be microspheres, which can be spherical or quasi-spherical, and their maximum outer diameter is not greater than 2 mm.

[0048] Furthermore, a gas flow valve is provided in the through hole 23, so that the gas outside the smoking device 2 flows unidirectionally into the heating cavity 21, that is, the gas in the heating cavity 21 cannot flow back to the outside of the smoking device 2 through the through hole 23, and only allows the low-temperature gas outside to enter the heating cavity 21 for flue gas cooling.

[0049] Of course, the through hole 23 is actually a channel, and one end of the channel close to the heating cavity 21 communicates with the bottom of the heating cavity 21 as close to the middle position as possible, so that the low-temperature outside air can be supplemented to the middle position at the end of the heating section 12 of the cigarette rod 1 and enter the tobacco shreds to be mixed with the heated flue gas; and there are a plurality of through holes 23, which are evenly arranged on the outer side wall of the smoking device 2.

[0050] Moreover, a cooling section 14 is provided between the suction section 11 and the heating section 12 to further cool the heated flue gas entering the suction section 11.

[0051] Finally, the heating needle 22 is a sensor, an electromagnetic coil is provided on the inner side wall of the heating cavity 21, and a power supply 24 for supplying power to the electromagnetic coil and a control module 25 for controlling the operation of the power supply 24 are provided in the smoking device 2.

[0052] Embodiment 3, as Figure 3 shown, for the convenience of understanding, the present invention also provides a uniform heating method for a cigarette uniform heating structure with enhanced air flow disturbance in any of the above embodiments, including the following steps:

[0053] S1: Add a number of cavity balls in the heating section of the cigarette rod;

[0054] S2: Insert the cigarette rod into the heating cavity, so that the heating needle in the heating cavity is inserted into the heating section of the cigarette rod;

[0055] S3: Start the heating needle to work to heat the heating section of the cigarette rod, and at the same time heat the cavity balls surrounding the heating needle;

[0056] S4: The high temperature generated by the heating needle working destroys the cavity ball wall structure, so that the heated gas in the inner cavity of the cavity ball wall expands and is released;

[0057] S5: The heated gas flows towards the peripheral tobacco shreds, heats the peripheral tobacco shreds far from the heating needle, and separates out the tobacco release substances.

[0058] S6: Gas flows into the heating cavity through the through hole on the side wall of the smoking device and is mixed with the heated smoke in the heating cavity, thereby reducing the temperature of the smoke entering the suction section.

[0059] Certainly, when step S4 is executed, the cavity ball wall melts after being heated by the heating needle, and releases the high-pressure heated non-combustible and non-toxic gas in the inner cavity.

[0060] Moreover, when step S6 is executed, the gas flow valve in the through hole on the side wall of the smoking device enables the gas outside the smoking device to flow unidirectionally into the heating cavity.

[0061] The structure of a cigarette uniform heating structure with enhanced air flow disturbance according to the present invention is simple. By generating an air flow inside the heated cigarette and flowing it to the peripheral tobacco part after being heated, the high-temperature air flow is transmitted to the peripheral tobacco part, making the heated tobacco evenly heated. At the same time, external cold air flows in, effectively alleviating the problem of high inlet temperature.

[0062] The present invention is not limited to the specific embodiments described above, and the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made based on the technical essence of the present invention to the above embodiments shall be included in the protection scope of the present invention.
