Description

Technical Field

[0001] The invention belongs to the technical field of heated smoking articles, and in particular relates to a side-type heated smoking article used for heating cigarettes. Background Art

[0002] Heated cigarettes are one of the important categories of new tobacco products. The atomization matrix segment is heated to 200℃-400℃ through an electric heating device, thereby producing smoke similar to traditional cigarettes for consumers to inhale. By lowering the temperature, the harmful substances produced when the cigarette is burned are reduced, thereby reducing harm to the human body.

[0003] In the existing heated smoking devices, two heating methods are generally used, namely central heating and circumferential heating. Specifically, a heating needle is inserted into the heated cigarette to achieve central heating; a heating cylinder is used to cover the heated cigarette to achieve circumferential heating.

[0004] However, in actual use, as the heat is transferred, the temperature gradually decreases. Regardless of whether central heating or circumferential heating is used, the lateral heating path relative to the cigarette is only a distance equal to the radius of the cigarette.

[0005] What needs to be known is that during the heating process of cigarettes, the atomized matrix segment releases different substances at different temperatures, but the existing heating method will cause the lateral heating path of the cigarette to be shorter, making it impossible to form a larger temperature gradient in the diameter direction of the cigarette, resulting in insufficient richness of the types of smoke released by the atomized matrix segment. Summary of the invention

[0006] The purpose of the present invention is to provide a side-type heating smoking device for heating cigarettes, which heats the cigarette by placing a heating body on one side of the cigarette, so that the lateral heat transfer path of the heating body in the cigarette is longer, thereby forming a larger temperature gradient in the diameter direction of the cigarette, so that the atomization matrix section can release a richer variety of smoke, and the practicality is strong.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A side-type heating smoking device for heating cigarettes, comprising: A heating body for heating cigarettes; The heating body is in strip shape; When the cigarette is in the smoking device, the heating element is attached to the outer side of the cigarette; When the cigarette is in a vertical state, the length of the arc of the heating body in contact with the side wall of the cigarette at the same level is less than two-thirds of the circumference of the cigarette.

[0008] It is further defined that the heating body is an arc-shaped heating plate.

[0009] This structural design uses an arc-shaped heating plate as a heating body to heat cigarettes, has a large heating area, and is highly practical.

[0010] It is further defined that the heating body is a heating column.

[0011] Such a structural design uses the heating column as a heating body to heat the cigarette, has a simple structure, is easy to manufacture, and is highly practical.

[0012] It is further defined that the central axis of the heating column is parallel to the central axis of the cigarette.

[0013] Such a structural design can further simplify the structure of the heating column by setting the heating column as a straight column parallel to the central axis of the cigarette, making the manufacturing more convenient and more practical.

[0014] It is further defined that the heating columns are arranged in a spiral shape, and the minimum distance between two adjacent circles of the heating columns is greater than the diameter of the cigarette.

[0015] This structural design, by twisting the heating column into a spiral shape and limiting the minimum distance between two adjacent circles of heating columns, ensures that the heating body has a sufficient distance in the lateral heat transfer path, thereby fully utilizing the cigarettes and is highly practical.

[0016] It is further defined that the operating temperature of the heating body is first high and then low.

[0017] This structural design limits the working temperature of the heating body, allowing the cigarette to release smoke quickly at a higher temperature, and lowers the temperature before the cigarettes are baked at a higher temperature and develop a burnt smell, so that only the heat is kept warm. This shortens the preheating time of the smoking device and prevents the burnt smell from affecting the taste of the cigarette, making it very practical.

[0018] It is further defined that the heating body includes a main body and a heating wire, the heating wire is coiled on the main body, and the density of the heating wire gradually decreases from top to bottom.

[0019] This structural design, by limiting the density of the heating wire, makes the temperature of the upper part of the heating body higher than that of the lower part of the heating body, thereby forming a temperature difference between the upper and lower ends of the heating body, so that there is also a temperature difference in the vertical direction of the cigarette, further enriching the types of smoke released after the atomization matrix section is heated, and is more practical.

[0020] It is further defined that there are multiple heating bodies, and the multiple heating bodies are located at different heights of the cigarette; The plurality of heating bodies generate heat in sequence.

[0021] Such a structural design, by setting heating bodies at different heights and controlling different heating bodies to work in sequence, heats different positions of the cigarette at different times, and can achieve rapid heating of the cigarette during the first few puffs of the cigarette, allowing the cigarette to release sufficient smoke, thereby reducing the preheating time of the cigarette by the smoking device; at the same time, it can also avoid the problem of excessively high smoke temperature due to the rapid loss of moisture in the cigarette in the early stage, and insufficient moisture in the smoke in the later stage of smoking, which affects the smoking taste, and is highly practical.

[0022] It is further defined that the plurality of heating bodies are arranged in a staggered manner.

[0023] Such a structural design increases the distance between two adjacent heating bodies on the same side through the staggered arrangement of the heating bodies, and retains a sufficient vertical heat transfer path when the heating bodies generate heat in sequence.

[0024] It is further defined that the length of the arc of the heating body in contact with the side wall of the cigarette at the same level is less than one half of the circumference of the cigarette; The top end of the heating body located at the bottom is higher in height than the bottom end of the heating body located at the top.

[0025] Such a structural design limits the position of the heating body so that different heating bodies are on the same horizontal plane and cover the cigarettes at the same time. As the heating bodies heat up in sequence, when the latter heating body is working, the overlapping part of the cigarette corresponding to the latter heating body can reach the smoking temperature in a shorter time under the joint action of the previous heating body, thereby shortening the preheating time and being more practical.

[0026] It is further defined that it also includes a heat insulation sleeve, the heat insulation sleeve is provided with a hollow groove, the heating body is embedded in the hollow groove, and the inner wall of the heating body is flush with the inner wall of the heat insulation sleeve.

[0027] This structural design installs the heating body through an insulating sleeve, and utilizes the fit between the inner wall of the heating body and the inner wall of the insulating sleeve, so that the cigarette will not be pressed against the end of the heating body during the insertion of the smoking device, thereby preventing the cigarette from being inserted smoothly. It is very practical.

[0028] The invention adopting the above technical solution has the following advantages: 1. The heating element heats the cigarette on one side of the cigarette, so that the heat transfer path of the heating element in the cigarette is longer, thereby forming a larger temperature gradient in the diameter direction of the cigarette, so that the atomized matrix section can release a richer variety of smoke, which is more practical; 2. At the same time, by utilizing a larger temperature gradient in the diameter direction of the cigarette, the nicotine content in the smoke can be guaranteed while reducing the moisture release rate in the cigarette, thereby keeping the moisture content in the smoke relatively stable during the entire smoking process of the cigarette, and making the smoking taste better; 3. By limiting the working temperature of the heating body, the cigarette can release smoke quickly at a higher temperature, and before the cigarettes are baked at a higher temperature and have a burnt smell, the temperature is lowered and only heat preservation is performed, which shortens the preheating time of the smoking device and prevents the burnt smell from affecting the taste of the cigarette, and is highly practical. 4. By limiting the density of the heating wire, the temperature of the upper part of the heating body is higher than that of the lower part of the heating body, thereby forming a temperature difference between the upper and lower ends of the heating body, so that the cigarette also has a temperature difference in the vertical direction, further enriching the types of smoke released after the atomization matrix section is heated, and having strong practicality; 5. By setting heating bodies at different heights and controlling different heating bodies to work in sequence, different positions of the cigarette can be heated at different times, so that the cigarette can be quickly heated at the beginning of the first few puffs of the cigarette, so that the cigarette releases enough smoke and the preheating time of the cigarette can be reduced; at the same time, it can also avoid the problem that the smoke temperature is too high after the moisture in the cigarette is quickly lost in the early stage, and the problem that the moisture in the smoke is insufficient in the later stage of smoking, which affects the smoking taste, and the practicality is strong; 6. By staggering the heating elements, the distance between two adjacent heating elements on the same side is increased, and sufficient vertical heat transfer paths are retained when the heating elements generate heat in sequence; 7. By limiting the position of the heating body, different heating bodies are on the same horizontal plane and cover the cigarettes at the same time. When the heating bodies heat up in sequence, when the latter heating body is working, the overlapping part of the cigarette corresponding to the latter heating body can reach the smoking temperature in a shorter time under the joint action of the previous heating body, thus shortening the preheating time and having strong practicality; 8. The heating body is installed through the insulation sleeve, and the inner wall of the heating body fits the inner wall of the insulation sleeve, so that the cigarette will not be pressed against the end of the heating body during the insertion of the smoking device, thereby preventing the cigarette from being inserted smoothly. This is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0031] like Figure 1 to Figure 6 As shown, a side-type heating smoking device for heating cigarettes of the present invention comprises: A heating body for heating the cigarette 1; The heating body is strip-shaped; When the cigarette 1 is in the smoking device, the heating element is attached to the outer side of the cigarette 1; When the cigarette 1 is in a vertical state, the length of the arc of the heating body fitting against the side wall of the cigarette 1 at the same level is less than two-thirds of the circumference of the cigarette 1 .

[0032] like Figure 1-4 As shown, the heating body is an arc-shaped heating plate 21.

[0033] The arc-shaped heating plate 21 is used as a heating body to heat the cigarette 1, with a large heating area and strong practicality.

[0034] like Figure 5-6 As shown, the heating body is a heating column 22 .

[0035] The cigarette 1 is heated by using the heating column 22 as a heating body, which has a simple structure, is easy to manufacture, and is highly practical.

[0036] like Figure 5 As shown, the central axis of the heating column 22 is parallel to the central axis of the cigarette 1 .

[0037] By arranging the heating column 22 as a straight column parallel to the central axis of the cigarette 1, the structure of the heating column 22 can be further simplified, making the manufacturing more convenient and more practical.

[0038] like Figure 6 As shown, the heating columns 22 are arranged in a spiral shape, and the minimum distance between two adjacent circles of heating columns 22 is greater than the diameter of the cigarette 1.

[0039] By twisting the heating column 22 into a spiral shape and limiting the minimum distance between two adjacent circles of heating columns 22, the cigarette 1 can be fully utilized while ensuring that the heating body has a sufficient distance in the lateral heat transfer path, which is highly practical.

[0040] The operating temperature of the heating body is high at first and then low.

[0041] In fact, the heating body can also be controlled at a constant temperature according to actual conditions. This embodiment limits the working temperature of the heating body. A higher temperature can be used to make the cigarette 1 release smoke quickly. Before the cigarette 1 is baked at a higher temperature and a burnt smell appears, the temperature is lowered and only insulation is performed. This shortens the preheating time of the smoking device and prevents the burnt smell from affecting the taste of the cigarette. It is very practical.

[0042] like Figure 1-4 As shown, the heating body includes a main body and a heating wire 20. The heating wire 20 is coiled on the main body, and the density of the heating wire 20 gradually decreases from top to bottom.

[0043] In fact, according to actual conditions, the same density can be selected to install the heating wire 20 on the heating body, or a heating resistor can be directly used as the heating body. In this embodiment, the density of the heating wire 20 is limited so that the temperature of the upper part of the heating body is higher than the temperature of the lower part of the heating body, thereby forming a temperature difference between the upper and lower ends of the heating body, so that the cigarette 1 also has a temperature difference in the vertical direction, further enriching the types of smoke released after the atomization matrix section is heated, and having strong practicality.

[0044] like Figure 2-4 As shown, there are multiple heating bodies, and the multiple heating bodies are located at different heights of the cigarette 1; Multiple heating elements generate heat in sequence.

[0045] In fact, according to actual conditions, an integral heating body can be used to heat the cigarette 1. This embodiment arranges heating bodies at different heights and controls different heating bodies to work in sequence, so as to heat different positions of the cigarette 1 at different times. This can achieve rapid heating of the cigarette 1 during the first few puffs of the cigarette 1, so that the cigarette 1 releases sufficient smoke, thereby reducing the preheating time of the cigarette 1 by the smoking device. At the same time, it can also avoid the problem that the smoke temperature is too high after the moisture in the cigarette 1 is quickly lost in the early stage, and the problem of insufficient moisture in the smoke in the later stage of smoking, which affects the smoking taste, and has strong practicality.

[0046] like Figure 2-4 As shown, multiple heating bodies are arranged in a staggered manner.

[0047] In fact, the heating bodies can also be arranged in a vertical array according to actual conditions. In this embodiment, the distance between two adjacent heating bodies on the same side is increased by staggered arrangement of the heating bodies, so that sufficient vertical heat transfer paths are retained when the heating bodies generate heat in sequence.

[0048] like Figure 2-4 As shown, the arc length of the heating body fitting the side wall of the cigarette 1 at the same level is less than half of the circumference of the cigarette 1; The top end of the heating body located below is higher in height than the bottom end of the heating body located above.

[0049] In fact, according to actual conditions, the heating bodies can be completely separated in the vertical direction. In this embodiment, the positions of the heating bodies are limited so that different heating bodies are on the same horizontal plane and cover the cigarette 1 at the same time. Then, when the heating bodies heat up in sequence, when the latter heating body is working, the overlapping part of the cigarette 1 corresponding to the latter heating body can reach the smoking temperature in a shorter time under the joint action of the previous heating body, thereby shortening the preheating time and having strong practicality.

[0050] like Figure 1-6 As shown, it also includes a heat insulating sleeve 3, which is provided with a hollow groove, and the heating body is embedded in the hollow groove, and the inner wall of the heating body is flush with the inner wall of the heat insulating sleeve 3.

[0051] In fact, according to actual conditions, a mounting bracket can be provided in the smoking device to fix the heating element in the form of the mounting bracket. In this embodiment, the heating element is installed by means of the heat-insulating sleeve 3, and the inner wall of the heating element fits the inner wall of the heat-insulating sleeve 3, so that the cigarette 1 will not be pressed against the end of the heating element during the insertion of the smoking device, thereby preventing the cigarette 1 from being inserted smoothly. This has strong practicality.

[0052] In this embodiment, when in use, the cigarette 1 is inserted into the heat-insulating sleeve 3 so that the heating element is close to the side wall of the cigarette 1; The heating wire 20 in the uppermost heating body starts working, heating the side wall of the cigarette 1 through the main body of the heating body, until the temperature of the contact part between the cigarette 1 and the heating body rises to a level before the smell of burning appears, then the temperature is lowered and maintained, and the cigarette 10 is continuously heated; After the first heating body is heated for a certain period of time, the temperature of the first heating body is lowered again, and the second heating body is activated for heating, and the above steps are repeated until the suction is completed.

[0053] The above is a detailed introduction to a side-type heating smoking device for heating cigarettes provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
