Abstract
Description
Technical Field
[0001] This patent belongs to the field of heated smoke appliance technology, specifically relating to a circumferentially heated smoke appliance. Background Technology
[0002] Existing heated non-combustible appliances can be divided into two categories from the perspective of heating technology: core heating and circumferential heating.
[0003] Inner core heating: This refers to the heating element being inserted inside the cigarette. Its disadvantages are relatively obvious: the tobacco is heated unevenly, the outer part of the cigarette is not heated, the utilization rate of the cigarette is low, and the inner core heating element can stick to the tobacco, causing the tobacco to fall into the heating device when the cigarette is pulled out, resulting in cleaning problems.
[0004] Circumferential heating: refers to a heat source that is cylindrical and wraps around the outer wall of the cigarette for heating. Existing peripheral heating devices generally have three problems: (1) relatively slow preheating (generally more than 25 seconds); (2) poor consistency before and after heating; (3) off-flavors on the first puff. The slow preheating is because the peripheral heating area is large, the tobacco has a large heating area, and the heat is transferred to the inside of the tobacco slowly, resulting in a relatively slow overall temperature rise; the poor consistency before and after heating is because the heat is transferred from the outside of the tobacco to the inside. During the entire heating process, the outer tobacco is constantly being baked. After a certain period of baking, the outer tobacco will carbonize. Continuing to bake the carbonized tobacco will affect the smoking taste. Therefore, the smoking taste in the later stages of peripheral heating is not as good as the smoking taste in the early stages, resulting in poor consistency. The off-flavors on the first puff are mainly because the peripheral heater bakes the cigarette paper on the outer wall of the cigarette, which will mix with the paper taste in the smoke, resulting in off-flavors.
[0005] Circumferential heating, because heat is conducted from the outer wall of the cigarette to the inside, essentially heats the paper first and then the tobacco. Therefore, to avoid the paper-like taste, the circumferential heating temperature cannot be set too high; a low temperature results in slow preheating, while a fast preheating requires a high temperature, making it difficult to avoid the paper-like taste.
[0006] Current methods for addressing the issue of off-flavors on the first puff in circumferential heating appliances often involve lowering the preheating temperature and extending the preheating time, employing a "slow and steady" heating approach to minimize this problem. However, addressing the slow preheating issue requires the circumferential heater to operate at full power during the preheating phase, increasing the heating rate and employing a "high-heat reduction" approach. This inevitably leads to off-flavors on the first puff. Therefore, circumferential heating appliances often present a trade-off between achieving rapid preheating and avoiding off-flavors on the first puff.
[0007] Meanwhile, circumferential heating, due to heat conduction from the outer wall of the cigarette to the center, essentially heats the outer tobacco first and then the central tobacco, with the outer tobacco always at a higher temperature than the central tobacco. During the entire heating process, the outer tobacco, after being baked for a period of time, will carbonize. To ensure the inner tobacco is also heated, it must continue to provide heat. However, continuing to heat the already carbonized outer tobacco will produce a burnt flavor, affecting the smoking experience and resulting in inconsistent smoking taste throughout the cigarette. Existing circumferential heating devices often address this issue by lowering the initial heating temperature, using a "slow and steady" heating method to prolong the time it takes for the outer tobacco to begin carbonizing. However, this method also introduces another problem: the first few puffs of smoke are not full-bodied. Utility Model Content
[0008] The purpose of this patent is to provide a circumferential heating smoking device to improve the preheating speed and avoid the problem of off-flavors on the first puff and poor consistency of taste between puffs.
[0009] To solve the above-mentioned technical problems, this patent adopts the following technical solution:
[0010] A circumferentially heated smoking device is disclosed, which contains heated cigarettes and can heat the cigarettes to generate an aerosol for inhalation. The heating device includes a circumferential heater, an airflow disturbance device, a circumferential heating upper support, and a circumferential heating lower support. The circumferential heating upper support, circumferential heater, circumferential heating lower support, and airflow disturbance device are arranged from top to bottom along the axial direction of the heated cigarettes. The circumferential heater includes a segmented circumferential structure, which includes an upper heating element and a lower heating element arranged symmetrically. The heated cigarettes pass through the upper heating element and the lower heating element in sequence and are fixed to the top of the airflow disturbance device for heating.
[0011] Furthermore, both the upper and lower heating elements are circumferentially extending, meandering curved structures.
[0012] Furthermore, the circumferential heating upper support includes a heater upper limit structure and a cigarette guide structure.
[0013] Furthermore, the heater's upper limit structure is located above the cigarette guide structure.
[0014] Furthermore, the diameter of the heater's upper limit structure is larger than the diameter of the cigarette guide structure, which creates a stepped structure at the junction of the two components as a stop, enabling the circumferential heater to engage with the heater's upper limit structure.
[0015] Furthermore, the lower heating support includes a lower heater limiting structure, which is arranged in a hollow groove shape so that the bottom of the circumferential heater is embedded and connected.
[0016] Furthermore, the heating fume also includes a fan bracket, and the airflow disturbance device is connected to the circumferential heating lower bracket through the fan bracket.
[0017] Furthermore, the fan bracket includes bracket limiting ribs, and the circumferential heating lower bracket includes a connecting column sleeve structure;
[0018] The support limiting rib is equipped with a lower support connecting column that is fixedly connected to the connecting column sleeve structure.
[0019] Furthermore, the airflow disturbance device is equipped with vents at the bottom.
[0020] Furthermore, the heating appliance also includes an insulation pipe, which wraps around the circumferential heating upper support, the circumferential heater, and the circumferential heating lower support. The insulation pipe is arranged in a double-layer hollow closed structure.
[0021] Furthermore, a heating protective shell is provided on the outer surface of the insulation pipe.
[0022] Furthermore, the inner surface of the heating protective shell is provided with a positioning port and a lower bracket fixing screw post.
[0023] Furthermore, the circumferential heating upper support is provided with a protective shell positioning protrusion, and the positioning port has a groove-shaped structure that adapts to the protective shell positioning protrusion.
[0024] Furthermore, the lower bracket fixing screw post is located at the lower part of the heating protective shell to connect the circumferential heating lower bracket.
[0025] Furthermore, the upper end of the circumferential heater should not extend beyond the upper end of the tobacco section to avoid heating the filter rod of the cigarette during the cigarette baking process, which could produce an off-flavor.
[0026] Furthermore, the airflow disturbance device is a fan located at the bottom.
[0027] Furthermore, the fan is fixedly connected to the fan bracket by fixing screws. The fan is located below the circumferential heater. When rotating in the forward direction, it can provide airflow from bottom to top, and when rotating in the reverse direction, it can exhaust flue gas from top to bottom.
[0028] Furthermore, the circumferential heating support is hollow, allowing the tobacco segments of the heated cigarette to pass through.
[0029] Furthermore, the circumferential heating lower support is hollow, allowing airflow to pass through along the axial direction.
[0030] Furthermore, a lower support coil receiving port is provided on the outer surface of the circumferential heating lower support, and the circuit coil is placed in the lower support coil receiving port.
[0031] Furthermore, a fan coil receiving port is provided on the outer surface of the fan bracket, and the circuit coil is placed in the fan coil receiving port.
[0032] Furthermore, the fan bracket is hollow and arc-shaped. Along the upward airflow direction, the diameter of the hollow structure is reduced, which facilitates increasing the speed of airflow disturbance and accelerating the flow of hot air.
[0033] This patent provides a circumferentially heated smoking device. By incorporating an airflow disturbance device to assist circumferential heating and accelerate hot air flow, it solves the problems of slow heat conduction and slow heating speed. Simultaneously, after preheating, the bottom airflow disturbance device performs reverse exhaust, expelling the first puff of smoke mixed with a papery taste, thus solving the problem of off-flavors on the first puff. Furthermore, the peripheral heating element can adopt a segmented heating method, with the peripheral heating divided into upper and lower sections along the axis. Initially, only the upper part of the tobacco is heated, resulting in a smaller heating area and faster heating of the tobacco; the lower part of the tobacco is heated later, solving the problem of inconsistent heating between the two sections.
[0034] The airflow disturbance device in this patent is a fan. Through a combination of a circumferential heater and a bottom fan, during the preheating stage of smoking, the fan rotates forward to accelerate the flow of hot air within the heating chamber, improving heat transfer efficiency and reducing preheating time. Within 2-3 seconds after preheating, the fan rotates in reverse to expel the first puff of smoke mixed with a papery taste. The fan then stops working, allowing the user to smoke normally. It can also be used with a segmented heater, initially heating only the upper part of the tobacco and later heating the lower part, further shortening preheating time while preventing carbonization of the outer tobacco and improving consistency before and after smoking.

[0094] like Figures 1-17As shown, this patent provides a circumferentially heated smoking device. The device houses a heated cigarette 9 and heats the cigarette 9 to generate an aerosol for inhalation. The device includes a circumferential heater 1, an airflow disturbance device 2, a circumferential heating upper support 3, and a circumferential heating lower support 4. These components are arranged from top to bottom along the axial direction of the heated cigarette 9. The circumferential heater 1 includes a segmented circumferential structure 11, which comprises an upper heating element 112 and a lower heating element 113 arranged symmetrically. The heated cigarette 9 passes sequentially through the upper heating element 112 and the lower heating element 113 and is fixed to the top of the airflow disturbance device 2 for heating. The airflow disturbance device 2 is a fan located at the bottom. The segmented structure of the circumferential heater 1 forms an upper heating element 112 and a lower heating element 113. During the initial smoking stage of the cigarette 9, the upper heating element 112 only heats the upper section of the tobacco, resulting in a small heating area, rapid temperature rise, and short preheating time. During the later smoking stage, the lower heating element 113 heats the lower section. This ensures that the heating time for each section of tobacco is only half the total time, preventing over-baking of the outer parts of each section and avoiding excessive carbonization that produces a burnt taste. The heating circuit of the segmented circumferential structure 11 is divided axially into upper and lower sections, forming the upper heating element 112 and the lower heating element 113, both of which can be heated independently.
[0095] More specifically, the heated cigarette 9 is heated in the heating chamber, and the circumferential heater 1, the airflow disturbance device 2, the circumferential heating upper support 3 and the circumferential heating lower support 4 are all located near the heating chamber, or even combined to form the heating chamber.
[0096] More specifically, the fan includes a fan connector 21 connected to an external power source, thereby supplying power to the fan to rotate the fan blades 23 and generate airflow. Preferably, the fan is fixedly connected to the fan bracket 5 by a fixing screw 22, and the fan is located below the circumferential heater 1. When rotating in the forward direction, the fan can provide upward airflow, and when rotating in the reverse direction, the fan can exhaust flue gas from top to bottom.
[0097] Specifically, the circumferential heater 1 has a segmented circumferential structure 11 inside, with the upper heating element 112 and the lower heating element 113 both arranged in a meandering curve extending along the circumference. Preferably, the upper heating element 112 and the lower heating element 113 are symmetrically distributed and connected to a power supply for heating via a common electrode 111.
[0098] Specifically, there are stops below the circumferential heating upper support 3 and above the circumferential heating lower support 4 to fix the circumferential heater 1 along the axial direction.
[0099] More specifically, the circumferential heating upper support 3 is hollow, which can accommodate the tobacco shreds 91 of the heated cigarette 9 through which it passes. It includes a heater upper limit structure 31 and a cigarette guide structure 32. The heater upper limit structure 31 is located above the cigarette guide structure 32. The diameter of the heater upper limit structure 31 is larger than the diameter of the cigarette guide structure 32, so that a stepped structure is formed at the junction of the two components as a stop, thereby enabling the circumferential heater 1 to be engaged with the heater upper limit structure 31.
[0100] More specifically, the circumferential heating lower support 4 is hollow, allowing airflow to pass through along the axial direction. It includes a heater lower limiting structure 41, which is arranged in a hollow groove shape as a stop to allow the bottom of the circumferential heater 1 to be embedded and connected. As one embodiment, the outer surface of the circumferential heating lower support 4 is provided with a lower support coil receiving port 43, in which a circuit coil is disposed. As a specific implementation, when the heating appliance uses electromagnetic heating, an electromagnetic induction coil can be placed in the lower support coil receiving port 43.
[0101] More specifically, the upper end of the circumferential heater 1 should not exceed the upper end of the tobacco section 91 to avoid heating the filter rod of the cigarette during the heating and baking process of the cigarette 9, which would produce an off-flavor.
[0102] Specifically, the heating appliance also includes a fan bracket 5, which is located below the circumferential heating lower bracket 4 and fixed together with the circumferential heater 1. The fan bracket 5 has a hollow arc shape. (See reference...) Figure 17 Along the upward airflow direction, the diameter of the hollow structure decreases, which facilitates increasing the speed of airflow disturbance and accelerating the flow of hot air. The airflow disturbance device 2 is connected to the circumferential heating lower support 4 via the fan bracket 5, facilitating airflow guidance. It can be understood that the fan is located below the fan bracket 5 and is fixed to the fan bracket 5 as a combined structure, jointly achieving airflow guidance. As one embodiment, the outer surface of the fan bracket 5 is provided with a fan coil receiving port 51, and the circuit coil is disposed in the fan coil receiving port 51. As a specific implementation, when the heating appliance uses electromagnetic heating, an electromagnetic induction coil can be placed in the fan coil receiving port 51.
[0103] Specifically, the fan bracket 5 includes a bracket limiting rib 52, and the circumferential heating lower bracket 4 includes a connecting column sleeve structure 42; the bracket limiting rib 52 is provided with a lower bracket connecting column 53 that is fixedly connected to the connecting column sleeve structure 42. As one embodiment, the bracket limiting rib 52 simultaneously accommodates the lower bracket connecting column 53 and the fixing screw 22, so that the circumferential heating lower bracket 4, the fan bracket 5, and the airflow disturbance device 2 are tightly connected and combined. As a specific embodiment, the fan bracket 5 is provided with four external limiting structures, which are interference-fitted with the heating appliance housing, thereby fixing the combined components of the circumferential heater 1, airflow disturbance device 2, circumferential heating upper bracket 3, circumferential heating lower bracket 4, fan bracket 5, heat insulation pipe 6, and heating protective shell 7 of this patent in the heating appliance housing.
[0104] Specifically, the airflow disturbance device 2 has a vent 8 at its bottom. More specifically, a controllable vent 8 is provided at the lower part of the fan bracket 5, which can be connected to the outside air and is controlled by an electric drive device.
[0105] Specifically, the heating appliance also includes an insulation pipe 6, which surrounds the circumferential heating upper support 3, the circumferential heater 1, and the circumferential heating lower support 4. Preferably, the insulation pipe 6 is arranged as a double-layer hollow closed structure with an internal vacuum, the main function of which is to lock the temperature of the circumferential heater 1 inside the insulation pipe 6.
[0106] Specifically, the outer surface of the insulation pipe 6 is provided with a heating protection shell 7, which is located outside the insulation pipe 6 and is locked in the axial direction by the circumferential heating lower support 4.
[0107] Specifically, the inner surface of the heating protective shell 7 is provided with a positioning port 71 and a lower bracket fixing screw post 72, and the outer surface of the circumferential heating upper bracket 3 is provided with a protective shell positioning protrusion 33. The positioning port 71 is arranged as a groove structure to fit the protective shell positioning protrusion 33.
[0108] More specifically, the circumferential heating lower bracket 4 is provided with protective shell fixing screw holes 44, and the lower bracket fixing screw post 72 is located at the lower part of the heating protective shell 7 to connect the circumferential heating lower bracket 4.
[0109] The heating control process of this patent is as follows:
[0110] (1) During the preheating stage, the circumferential heater is at full power output and the vent is closed. At this time, the heating chamber is in a closed state, and the fan is turned on to rotate in the forward direction to accelerate the flow of hot air, so that the heat can be quickly conducted to the inside of the tobacco.
[0111] (2) After the preheating is completed, open the vent within 2-3 seconds. At this time, control the fan to rotate in the opposite direction to discharge the smoke mixed with the paper smell from the bottom vent in the heating chamber.
[0112] (3) During the suction stage, the fan stops working, and the electronic control system controls the upper and lower heating elements of the circumferential heater to work at the set working temperature by outputting power. At this time, the user can perform normal suction.
[0113] This patent has the following beneficial effects:
[0114] (1) The present invention has a simple structure. With the help of the fan to drive the airflow, the temperature conduction speed is accelerated, and the problem of excessive heat accumulation on the outer wall of the cigarette is avoided, which causes the paper taste to be too strong. At the same time, after the preheating is completed, the fan exhausts the air in the opposite direction, which can also discharge the smoke mixed with the paper taste through the bottom air hole. This solves the problem that the two cannot be achieved at the same time: fast circumferential heating and avoiding the first puff of smoke with a bad taste.
[0115] (2) At the same time, the preheating time can be further shortened by using the idea of segmented heating, which involves heating only the upper part of the tobacco in the early stage and the lower part of the tobacco in the later stage. This also avoids carbonization of the outer tobacco, solves the problem of long circumferential heating preheating time, and improves the problem of poor heating consistency before and after the cigarette.
