Description

A side-mounted heating device for heating cigarettes Technical Field

[0001] This invention belongs to the field of heated smoking device technology, and specifically relates to a side-type heated smoking device for heating cigarettes. Background Technology

[0002] Heated cigarettes are an important category of new tobacco products. They use an electric heating device to heat the atomizing matrix section to 200℃-400℃, thereby producing smoke similar to that of traditional cigarettes for consumers to inhale. By lowering the temperature, the harmful substances produced during the combustion of the cigarette are reduced, thus reducing harm to the human body.

[0003] In existing heated cigarette devices, two heating methods are generally used: 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 heat is transferred, the temperature gradually decreases. Whether central heating or circumferential heating is used, the distance relative to the transverse heating path of the cigarette is only the radius of the cigarette.

[0005] It is important to know that during the heating process of cigarettes, the atomizing matrix section releases different substances at different temperatures. However, the existing heating methods result in a short lateral heating path for cigarettes, which makes it impossible to form a larger temperature gradient in the diameter direction of the cigarette, thus leading to insufficient richness of smoke types released by the atomizing matrix section. Summary of the Invention

[0006] The purpose of this invention is to provide a side-mounted heating device for heating cigarettes. By placing the heating element on one side of the cigarette, the heating element heats the cigarette, resulting in a longer lateral heat transfer path within the cigarette. This creates a larger temperature gradient along the diameter of the cigarette, allowing the atomizing matrix section to release a wider variety of smokes, thus enhancing its practicality.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0008] A side-mounted cigarette heating device for heating cigarettes, comprising:

[0009] A heating element used to heat cigarettes;

[0010] The heating element is strip-shaped;

[0011] When the cigarette is inside the smoking device, the heating element is attached to the outside of the cigarette;

[0012] When the cigarette is in a vertical position, the arc length of the heating element that contacts the side wall of the cigarette at the same horizontal level is less than two-thirds of the circumference of the cigarette.

[0013] Furthermore, the heating element is an arc-shaped heating plate.

[0014] This structural design uses an arc-shaped heating element to heat the cigarette, resulting in a large heating area and strong practicality.

[0015] Further specifying, the heating element is a heating column.

[0016] This structural design uses a heating column as the heating element to heat the cigarette. It is simple in structure, easy to manufacture, and highly practical.

[0017] Furthermore, the central axis of the heating column is parallel to the central axis of the cigarette.

[0018] This structural design, by setting the heating column as a straight column parallel to the central axis of the cigarette, can further simplify the structure of the heating column, making it easier to manufacture and more practical.

[0019] Furthermore, the heating column is arranged in a spiral shape, and the minimum distance between two adjacent rings of the heating column is greater than the diameter of the cigarette.

[0020] This structural design, by twisting the heating column into a spiral shape and limiting the minimum distance between two adjacent rings of heating columns, ensures sufficient distance in the lateral heat transfer path of the heating element, thereby making full use of the cigarette and making it highly practical.

[0021] Furthermore, the operating temperature of the heating element is initially high and then decreases.

[0022] This structural design limits the temperature of the heating element during operation. The higher temperature allows the cigarette to release smoke quickly, and the temperature is lowered before the cigarette develops a burnt smell. This only keeps the cigarette warm, which shortens the preheating time of the device and prevents the burnt smell from affecting the taste of the cigarette. It is highly practical.

[0023] Further defined, the heating element includes a body and a heating wire, the heating wire is coiled on the body, and the density of the heating wire gradually decreases from top to bottom.

[0024] This structural design, by limiting the density of the heating wire, makes the temperature at the top of the heating body higher than that at the bottom, thus creating a temperature difference between the upper and lower ends of the heating body. This results in a temperature difference in the vertical direction of the cigarette, further enriching the types of smoke released after the atomizing matrix section is heated, making it highly practical.

[0025] Furthermore, there are multiple heating elements, and the multiple heating elements are located at different heights of the cigarette;

[0026] The multiple heating elements generate heat sequentially.

[0027] This structural design, by placing heating elements at different heights and controlling them to work sequentially, heats different parts of the cigarette at different times. This allows for rapid heating of the cigarette during the first few puffs, ensuring sufficient smoke release and reducing the preheating time of the smoking device. Simultaneously, it prevents the cigarette from losing moisture too quickly in the early stages, which could lead to excessively high smoke temperatures and insufficient moisture in the smoke later in the smoking process, affecting the smoking experience. This design is highly practical.

[0028] Furthermore, the heating elements are arranged in an alternating manner.

[0029] This structural design, through the staggered arrangement of heating elements, increases the distance between two adjacent heating elements on the same side, thus preserving a sufficient vertical heat transfer path when the heating elements heat up sequentially.

[0030] Furthermore, the arc length of the heating element that adheres to the side wall of the cigarette at the same horizontal level is less than one-half of the circumference of the cigarette;

[0031] The top of the lower heating element is higher than the bottom of the upper heating element in terms of height.

[0032] This structural design, by limiting the position of the heating elements, allows different heating elements to be on the same horizontal plane and simultaneously cover the cigarette. As the heating elements heat up sequentially, when a later heating element works, the overlapping part of the cigarette corresponding to that later heating element can reach the smoking temperature in a shorter time under the combined action of the previous heating elements, thus shortening the preheating time and making it highly practical.

[0033] Further, it also includes a heat insulation sleeve, on which a hollow groove is formed, and the heating element is embedded in the hollow groove, with the inner wall of the heating element flush with the inner wall of the heat insulation sleeve.

[0034] This structural design, which uses a heat insulation sleeve to install the heating element and utilizes the fit between the inner wall of the heating element and the inner wall of the heat insulation sleeve, prevents the cigarette from pressing against the end of the heating element during insertion into the smoking device, thus avoiding the problem of difficult insertion. It is highly practical.

[0035] The invention employing the above technical solution has the following advantages:

[0036] 1. By heating the cigarette on one side with a heating element, the heat transfer path in the cigarette is longer, which in turn creates a larger temperature gradient in the diameter direction of the cigarette. This allows the atomizing matrix section to release a wider variety of smokes, making it highly practical.

[0037] 2. At the same time, by utilizing a larger temperature gradient along the diameter of the cigarette, the rate of moisture release from the cigarette can be reduced while ensuring the nicotine content in the smoke. This results in a relatively stable moisture content in the smoke throughout the entire smoking process, leading to a better smoking experience.

[0038] 3. By limiting the temperature of the heating element during operation, the cigarette can release smoke quickly at a higher temperature. Before the cigarette develops a burnt smell at a high temperature, the temperature is lowered and only the temperature is maintained. This shortens the preheating time of the smoking device and also prevents the burnt smell from affecting the taste of the cigarette. It is highly practical.

[0039] 4. By limiting the density of the heating wire, the temperature at the top of the heating body is higher than that at the bottom, thus creating a temperature difference between the upper and lower ends of the heating body. This results in a temperature difference in the vertical direction of the cigarette, further enriching the types of smoke released after the atomizing matrix section is heated, making it highly practical.

[0040] 5. By setting heating elements at different heights and controlling them to work sequentially, different parts of the cigarette are heated at different times. This allows for rapid heating of the cigarette during the first few puffs, ensuring sufficient smoke release and reducing the preheating time of the smoking device. Simultaneously, it avoids the problem of excessively high smoke temperature due to rapid moisture loss in the early stages, which could lead to insufficient moisture in the smoke later in the smoking process, affecting the smoking experience. This design is highly practical.

[0041] 6. By staggering the heating elements, the distance between two adjacent heating elements on the same side is increased, thus preserving a sufficient vertical heat transfer path when the heating elements heat up sequentially;

[0042] 7. By limiting the position of the heating elements, different heating elements can be placed on the same horizontal plane and simultaneously cover the cigarette. As the heating elements heat up in sequence, when a later heating element works, the overlapping part of the cigarette corresponding to the later heating element can reach the smoking temperature in a shorter time under the combined action of the previous heating element, thus shortening the preheating time and making it highly practical.

[0043] 8. The heating element is installed by means of a heat insulation sleeve, and the inner wall of the heating element fits against the inner wall of the heat insulation sleeve, so that the cigarette does not press against the end of the heating element when it is inserted into the smoking device, thus preventing the cigarette from being inserted too smoothly. This is highly practical. Attached Figure Description

[0051] The symbols for the main components are explained as follows: Cigarette 1, Heating wire 20, Arc-shaped heating element 21, Heating column 22, Heat insulation sleeve 3. Detailed Implementation

[0052] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0053] As shown in Figures 1 to 6, a side-type heating device for heating cigarettes according to the present invention includes:

[0054] A heating element for heating cigarette 1;

[0055] The heating element is strip-shaped;

[0056] When cigarette 1 is inside the smoking device, the heating element is attached to the outside of cigarette 1;

[0057] When cigarette 1 is in a vertical position, the arc length of the heating element that adheres to the side wall of cigarette 1 at the same horizontal level is less than two-thirds of the circumference of cigarette 1.

[0058] As shown in Figures 1-4, the heating element is an arc-shaped heating plate 21.

[0059] The cigarette 1 is heated by using an arc-shaped heating element 21 as the heating body. It has a large heating area and is highly practical.

[0060] As shown in Figure 5-6, the heating element is a heating column 22.

[0061] The cigarette 1 is heated by using the heating column 22 as the heating element. The structure is simple, easy to manufacture, and highly practical.

[0062] As shown in Figure 5, the central axis of the heating column 22 is parallel to the central axis of the cigarette 1.

[0063] By setting 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 it easier to manufacture and more practical.

[0064] As shown in Figure 6, the heating column 22 is arranged in a spiral shape, and the minimum distance between two adjacent rings of heating column 22 is greater than the diameter of the cigarette 1.

[0065] By twisting the heating column 22 into a spiral shape and limiting the minimum distance between two adjacent heating columns 22, the cigarette 1 can be fully utilized while ensuring that the heating body has sufficient distance in the lateral heat transfer path, making it highly practical.

[0066] The operating temperature of the heating element is initially high and then decreases.

[0067] In practice, the heating element can also be kept at a constant temperature depending on the actual situation. In this embodiment, the temperature of the heating element during operation is limited. The higher temperature allows the cigarette 1 to release smoke quickly. Before the cigarette 1 develops a burnt smell at a higher temperature, the temperature is lowered and only heat is maintained. This shortens the preheating time of the smoking device and also avoids the burnt smell from affecting the taste of the cigarette. It is highly practical.

[0068] As shown in Figures 1-4, the heating element includes a body and a heating wire 20. The heating wire 20 is coiled on the body, and the density of the heating wire 20 gradually decreases from top to bottom.

[0069] In practice, the same density can be selected to install the heating wire 20 on the heating body, or a heating resistor can be used directly as the heating body. In this embodiment, by limiting the density of the heating wire 20, 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. This results in a temperature difference in the vertical direction of the cigarette 1, further enriching the types of smoke released after the atomizing matrix section is heated, which is highly practical.

[0070] As shown in Figure 2-4, there are multiple heating elements, which are located at different heights on cigarette 1.

[0071] Multiple heating elements generate heat sequentially.

[0072] In practice, depending on the actual situation, an integral heating element can be used to heat the cigarette 1. In this embodiment, by setting heating elements at different heights and controlling different heating elements to work sequentially, different positions of the cigarette 1 are heated at different times. This can quickly heat the cigarette 1 during the first few puffs, allowing the cigarette 1 to release sufficient smoke and reducing the preheating time of the smoking device. At the same time, it can also prevent the moisture in the cigarette 1 from being lost too quickly in the early stage, resulting in excessively high smoke temperature, and in the later stage of smoking, insufficient moisture in the smoke, which affects the smoking experience. This method is highly practical.

[0073] As shown in Figure 2-4, multiple heating elements are arranged in an alternating manner.

[0074] In practice, the heating elements can also be arranged in a vertical array according to the actual situation. In this embodiment, the distance between two adjacent heating elements on the same side is increased by staggering the heating elements, so that sufficient vertical heat transfer path is reserved when the heating elements heat up in sequence.

[0075] As shown in Figure 2-4, the length of the arc in which the heating element adheres to the side wall of cigarette 1 at the same horizontal level is less than half the circumference of cigarette 1.

[0076] The top of the lower heating element is higher than the bottom of the upper heating element in terms of height.

[0077] In practice, depending on the actual situation, the heating elements can be completely separated in the vertical direction. In this embodiment, by limiting the position of the heating elements, different heating elements are on the same horizontal plane and simultaneously cover the cigarette 1. As the heating elements heat up in sequence, when the next heating element works, the overlapping part of the cigarette 1 corresponding to the next heating element can reach the smoking temperature in a shorter time under the combined action of the previous heating element, thus shortening the preheating time and making it more practical.

[0078] As shown in Figures 1-6, it also includes a heat insulation sleeve 3, which has a hollowed-out groove. The heating element is embedded in the hollowed-out groove, and the inner wall of the heating element is flush with the inner wall of the heat insulation sleeve 3.

[0079] In practice, depending on the actual situation, a mounting bracket can be set in the smoking device to fix the heating element. In this embodiment, the heating element is installed by the heat insulation sleeve 3, and the fit between the inner wall of the heating element and the inner wall of the heat insulation sleeve 3 is used to prevent the cigarette 1 from pressing against the end of the heating element during the insertion of the smoking device, thus avoiding the problem of the cigarette 1 not being inserted smoothly. This is highly practical.

[0080] In this embodiment, when in use, the cigarette 1 is inserted into the heat insulation sleeve 3 so that the heating element is in contact with the side wall of the cigarette 1.

[0081] The heating wire 20 in the uppermost heating element operates, heating the side wall of the cigarette 1 through the main body of the heating element until the temperature of the part of the cigarette 1 that is in contact with the heating element rises to the point where a burnt smell appears. Then the temperature is lowered and maintained to continuously heat the cigarette 10.

[0082] After the first heating element has been heated for a certain period of time, the temperature of the first heating element is lowered again, and the second heating element is activated. The above steps are repeated until the suction is completed.

[0083] The foregoing has provided a detailed description of a side-type heating device for heating cigarettes provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
