Description

Technical Field

[0001] This utility model relates to the technical field of heated non-combustible electronic cigarette devices, and more specifically, to an electronic cigarette device that can uniformly heat a cigarette. Background Technology

[0002] Heated tobacco products (HTMP) work by heating the tobacco inside a cigarette, causing a pyrolysis reaction. This heats the tobacco to a level sufficient to release its flavor and smoke without burning it, providing a similar satisfaction to smoking a cigarette while significantly reducing the production of harmful substances during cigarette combustion, thus avoiding the inhalation of these harmful substances.

[0003] Existing heated tobacco products are devices that utilize heated tobacco technology. They generally include a casing, a power supply component, and a heating component. The power supply component contains a battery that powers the heating component, which, when powered, heats the tobacco portion of the cigarette to produce smoke. The cigarette typically consists of a mouthpiece and a tobacco portion. The tobacco portion contains tobacco material that produces smoke, which is made by absorbing a portion of nicotine, e-liquid, or flavoring components.

[0004] Existing heated tobacco products on the market use heating elements such as heating tubes, induction plates, heating needles, and heating plates as heating sources. They employ resistance wire heating and electromagnetic induction coil heating, respectively, to directly heat the outer perimeter of the tobacco through the heating tube, or to heat the inside of the tobacco through the induction plate, heating needle, or heating plate located inside the tobacco. Both methods limit the heating of the tobacco to localized, concentrated areas, resulting in uneven heating. The tobacco near the heating source overheats and burns, producing a burnt taste, while the tobacco further away from the heating source is not fully heated, leading to waste. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0032] This utility model relates to an electronic cigarette device that can uniformly heat the cigarette. For ease of description, as follows: Figure 1 As shown, the electronic cigarette device of this utility model is placed vertically with the insertion port 110 facing upwards. If there are descriptions of the various parts of the electronic cigarette device such as "upper, lower, upper part, lower part, bottom, upper end, lower end, top end, bottom end, above, below, bottom surface, upward, downward, horizontal, vertical", etc., they all refer to the positional relationship of the various parts when the electronic cigarette device is placed vertically with the insertion port 110 facing upwards.

[0033] Example

[0034] This invention relates to an electronic cigarette device that can uniformly heat a cigarette stick, allowing for simultaneous heating and baking of both the outer wall and the interior of the cigarette stick.

[0035] like Figure 1 As shown, this utility model discloses an electronic cigarette device capable of uniformly heating a cigarette, comprising a housing 1 and a heating device 2, a circuit control device 3, and a battery 4 disposed within the housing 1. The heating device 2 is located at the upper part of the device, while the circuit control device 3 and the battery 4 are located at the lower part. The upper end of the device has an upper cover 11, and the lower end has a bottom cover 12. The upper cover 11 has an insertion port 110 for inserting a cigarette into the heating device 2. Next to the insertion port 110 is a sliding cover 111, which can slide parallel to the insertion port 110 to cover the insertion port 110 when the device is not in use, preventing debris from falling into the heating device. Additionally, a push-button switch 30 is provided on the side of the housing 1, which can turn the electronic cigarette device on or off. The push-button switch 30 is part of the circuit control device 3. A display screen 34 is also provided on the side of the housing 1 to display the control parameters of the device; the display screen 34 is also part of the circuit control device 3.

[0036] like Figure 2As shown, the cigarette stick 5, which is adapted to the electronic cigarette device of the present invention that can uniformly heat the cigarette stick, includes a mouthpiece section 51 and a tobacco section 52. The mouthpiece section 51 includes a filter material for filtering out impurities such as smoke, e-liquid, and condensate. The tobacco section 52 includes a material such as tobacco that can be baked, which is used to bake out cigarette smoke after heating.

[0037] like Figure 3 , Figure 4 , Figure 9 As shown, the baking device 2 includes a metal heat-conducting cup 22 and a heating plate 21 closely attached to the bottom of the metal heat-conducting cup 22. The metal heat-conducting cup 22 has an opening at the upper end and a bottom wall at the lower end. The metal heat-conducting cup 22 has a receiving cavity 220 adapted for inserting a cigarette. A first axial groove 221 is provided along the axial direction on the inner side wall of the metal heat-conducting cup 22. The first axial groove 221 can be configured as a straight line, a curved shape, or a spiral shape on the inner wall surface of the metal heat-conducting cup 22. The first axial groove 221 and the outer wall surface of the cigarette form an airflow channel 200. Except for the first axial groove 221, the inner side wall of the metal heat-conducting cup 22 is in contact with the outer wall of the cigarette. The bottom of the metal heat-conducting cup 22, i.e. the bottom of the receiving cavity 220, is provided with a bottom groove 222 that communicates with the first axial groove 221. The bottom groove 222 is not limited in shape, but mainly it can form a certain gap with the bottom of the inserted cigarette to form part of the airflow channel 200. The first axial groove 221 and the bottom groove 222 together with the cigarette form an air intake channel 200 that enters the bottom of the cigarette from top to bottom. When the user smokes through the mouthpiece section 51 of the cigarette, the outside air can flow through the air intake channel 200 and enter the bottom of the cigarette 5. After entering the interior of the cigarette at the bottom of the cigarette 5, it is inhaled into the user's mouth. When the heating plate 21 is powered on, it heats the metal heat-conducting cup 22, which is placed in close contact with it. The metal heat-conducting cup 22 conducts heat from bottom to top, and further conducts heat to the outer wall of the tobacco segment 52 of the cigarette 5 and the airflow flowing through the air intake channel 200. The outer wall of the tobacco segment 52 of the cigarette 5 is heated and further conducts heat radially inward. At the same time, the airflow in the air intake channel 200 is heated and enters the interior of the cigarette 5 from the bottom, further conducting heat axially to the interior of the tobacco segment 52 of the cigarette 5. This utility model of a heated non-combustible tobacco device with the above structure can simultaneously heat the outer wall and interior of the tobacco segment 52 of the cigarette 5, and can quickly and efficiently preheat and heat the tobacco components inside the cigarette, so that it can quickly produce a sufficient amount of smoke for the user to smoke.

[0038] In this embodiment, the heating plate 21 is a disc-shaped ceramic heating element. The bottom of the heating plate 21 is also connected to an electrode lead 211, which is electrically connected to the circuit control device 3 so as to supply power to the heating plate 21 to make it heat up.

[0039] In this embodiment, to achieve better thermal conductivity, the metal heat-conducting cup 22 is made of aluminum or an aluminum alloy. The outer wall and / or bottom wall of the metal heat-conducting cup 22 are composed of an oxide layer. The oxide layer has good insulation properties, but because the oxide layer is very thin, it does not affect the thermal conductivity. In particular, when the metal heat-conducting cup 22 is made of aluminum or an aluminum alloy, the oxide layer is an aluminum oxide layer, which has excellent insulation and thermal conductivity properties.

[0040] like Figure 5 , Figures 7-9 As shown, in this embodiment, the baking device 2 further includes a cigarette guide tube 23 adapted for cigarette insertion. A metal heat-conducting cup 22 is coaxially fixedly connected to the lower part of the cigarette guide tube 23. The inner wall of the cigarette guide tube 23 is provided with a second axial groove 231 communicating with the first axial groove 221. The portion of the second axial groove 231 enclosed by the cigarette also constitutes part of the air intake channel 200. The upper part of the cigarette guide tube 23 is provided with a radially protruding support portion 232. The cigarette guide tube 23 serves to connect and fix the metal heat-conducting cup 22. The cigarette guide tube 23 is fixed in the mounting cylinder 20 described below by the support portion 232, avoiding direct contact and fixation between the heating plate 21, the metal heat-conducting cup 22 and the mounting cylinder 20, and preventing heat loss due to outward conduction. The cigarette guide tube 23 is made of heat-resistant PEEK material. The cigarette guide tube 23 also serves to guide the cigarette into the receiving cavity 220 of the metal heat-conducting cup 22, and its second axial groove 231 serves to guide the airflow downward into the metal heat-conducting cup 22.

[0041] like Figure 6 , Figures 7-9 As shown, in this embodiment, a sealing guide sleeve 24 is also fitted onto the upper part of the cigarette guide tube 23. The sealing guide sleeve 24 is made of high-temperature resistant silicone material. The center of the sealing guide sleeve 24 is provided with a sleeve hole 240 adapted for cigarette insertion. An air inlet hole 241 is radially provided at the connection between the sealing guide sleeve 24 and the cigarette guide tube 23. The air inlet hole 241 communicates with the second axial groove 231 and forms part of the air intake channel 200. The axial middle inner diameter of the sealing guide sleeve 24 is reduced to the sleeve hole 240, and the inner diameters at both ends are larger than the sleeve hole 240. In this way, the sealing guide sleeve 24 can stably clamp the cigarette 5. At the same time, after the cigarette 5 is inserted into the sleeve hole 240, there is no gap between the inner wall of the sleeve hole 240 and the cigarette, which can prevent the air intake channel 200 from being directly connected to the outside air. The air intake channel 200 is only connected to the air inlet hole 241, that is, the airflow entering the air intake channel 200 must first pass through the air inlet hole 241.

[0042] like Figure 7 , Figure 8As shown, in this embodiment, the outer walls of the cigarette tube 23 and the metal heat-conducting cup 22 are surrounded by a heat-insulating sleeve 25, and the bottom of the heating plate 21 is provided with a heat-insulating pad 26. Both the heat-insulating sleeve 25 and the heat-insulating pad 26 can greatly reduce heat radiation to the outside, so that the heat is more concentrated in the metal heat-conducting cup 22.

[0043] The baking device 2 also includes a mounting cylinder 20, a heat insulation sleeve 25, a smoke pipe 23, a metal heat-conducting cup 22, a heating plate 21, and a heat insulation pad 26, all housed within the mounting cylinder 20. The smoke pipe 23 has a radially protruding support 232 at its upper part, which abuts against the inner wall of the mounting cylinder 20. The bottom of the heat insulation pad 26 abuts against the inner bottom of the mounting cylinder 20. Additionally, an external heat insulation sleeve 29 is fitted onto the outer wall of the mounting cylinder 20. This external heat insulation sleeve 29 also provides insulation, significantly reducing further heat radiation and preventing the outer casing 1 from becoming too hot to handle during use.

[0044] A support plate 27 is also fitted onto the outer wall of the sealing guide sleeve 24. A pressure plate 28 is provided on the support plate 27 to press down on the sealing guide sleeve 24 and expose the sleeve hole. The support plate 27 and pressure plate 28 are used to support and fix the sealing guide sleeve 24. The support plate 27 and pressure plate 28 are also provided with through holes coaxially arranged with the insertion port 110 of the upper cover and the sleeve hole 240 of the sealing guide sleeve 24.

[0045] An optical sensor 31 is installed on the support plate 27, aligned with the air inlet hole 241. The optical sensor 31 is used to detect whether the cigarette is inserted into the cigarette guide tube and the metal heat-conducting cup. At the same time, a pressure sensor 32 is also installed on the support plate 27, aligned with the air inlet hole, to detect the airflow. The optical sensor 31 and the pressure sensor 32 are part of the circuit control device 3.

[0046] In this embodiment, the circuit control device 3 includes a microprocessor (not shown in the figure) and a temperature sensor 33 disposed on the outer wall of the metal heat-conducting cup 22. The temperature sensor 33 is also part of the circuit control device 3. The temperature sensor 33 can be used to detect the temperature of the metal heat-conducting cup 22 and feed it back to the microprocessor to control the input power of the heating plate 21 so as to control the temperature of the metal heat-conducting cup 22, and thus control the heat generation, temperature and smoke volume of the smoking device for heating the cigarette.

[0047] like Figures 7-9As shown, the heating device 2 of this utility model's electronic cigarette device, when a cigarette 5 is inserted, the optical sensor 31 detects the insertion and triggers the heating device 2 to start, energizing the heating plate 21 for preheating. The heating plate 21 emits heat and conducts it upwards to the entire metal heat-conducting cup 22. The side wall of the metal heat-conducting cup 22, which is in direct contact with the cigarette 5, directly conducts heat to the outer wall of the cigarette 5. After receiving heat, the outer wall of the cigarette 5 conducts it radially towards the tobacco material inside the cigarette. Simultaneously, the heat from the metal heat-conducting cup 22 is conducted to the first axial groove 221 and the bottom groove 222, heating the air within them. After the preset preheating time is reached, the circuit control device 3 issues a preheating end indication, and the user can then begin smoking in the mouthpiece section 51 of the cigarette. When the user smokes, an upward airflow of smoke is generated inside the cigarette, which... Figure 9 As indicated by the continuous upward hollow arrows. At this time, a negative pressure is generated inside the cigarette 5 and the receiving cavity 220 inside the metal heat-conducting cup 22. Outside air can then enter the air intake channel 200 formed by the second axial groove 231, the first axial groove 221, the bottom groove 222, and the cigarette through the air intake hole 241, forming an intake airflow. This intake airflow is as follows: Figure 9 As indicated by the continuous solid arrow pointing downwards. At this time, the air pressure sensor 32 detects the inhaled airflow, which can trigger the heating plate 21 to continue heating. The outer wall of the cigarette 5 continues to receive heat, while the heated air in the first axial groove 221 and the bottom groove 222 continues to flow into the interior of the cigarette 5. The tobacco material inside the cigarette 5 simultaneously receives heat from the outer wall of the cigarette and the hot air from the bottom of the cigarette, so that the tobacco material inside the cigarette 5 is heated quickly and evenly, avoiding the problem of overheating and burning caused by uneven heating inside the cigarette, as well as the problem of insufficient heating and incomplete utilization of the tobacco.

[0048] In other embodiments, the heating plate 21 may also be a disc-shaped heating coil or a disc-shaped metal heating element.

[0049] In other embodiments, at least a portion of the bottom wall of the metal heat-conducting cup 22 is formed by a heating plate 21. This arrangement allows the heating plate 21 to directly contact the air in the bottom groove 222 for heating, which can heat the intake airflow in the air intake channel 200 more quickly, so that more heat can be conducted to the inside of the cigarette through the air.

[0050] In other embodiments, the circuit control device 3 further includes an accelerometer or gravity sensor for detecting the movement state of the smoking device, and a touch sensor for sensing human touch actions. The accelerometer or gravity sensor detects the movement state of the smoking device and can pre-calculate preheating or power-on / off procedures by detecting human smoking actions. The touch sensor can sense human touch actions and trigger power-on / off procedures, thus replacing the button switch.

[0051] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
