Description

Heating components and heat-not-burn smoking devices Technical Field

The present application relates to the technical field of heated smoking articles, and in particular to a heating component and a heat-not-burn smoking article.

Background technique

Traditional tobacco needs to be ignited by open flames to produce tobacco smoke. During the high-temperature combustion process, tobacco releases thousands of harmful compounds, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), tar, etc. Heat-not-burn cigarettes have the characteristics of no open flames, no ash, no second-hand smoke, 90% harm reduction, and 90% of the taste of traditional cigarettes. Therefore, heat-not-burn electronic cigarettes are considered to be a good substitute for traditional cigarettes.

technical problem

According to the different heating methods, the current heat-not-burn tobacco devices are generally divided into circumferential heating type, central heating type and air heating type. Among them, the circumferential heating type non-burning electronic cigarettes generally have heating wires or heating circuits on the heating tube, and the cigarette is inserted into the heating tube. The heat is gradually transferred from the periphery of the cigarette to the inside of the cigarette to heat the cigarette circumferentially. The central heating type heat-not-burn tobacco devices generally have heating wires or heating circuits on ceramic sheets or ceramic needles, and the ceramic sheets or ceramic needles are inserted into the center of the cigarette. The heat is gradually transferred from the inside of the cigarette to the periphery of the cigarette to heat the center of the cigarette. The air heating type heat-not-burn tobacco devices generally have heating wires or heating circuits on the heating body, which first heats the air and then uses the heated air to heat the cigarette.

However, since the heating wire or heating circuit is generally made of metal (such as stainless steel, iron-chromium-aluminum, etc.), the heating efficiency of the heating wire or heating circuit is low, and the heat generated by the heating wire or heating circuit can generally only heat the cigarette through heat conduction (through contact heat conduction or air heat transfer), so there are problems such as low heating efficiency and poor heating uniformity. In addition, since the heating wire or heating circuit is generally exposed to the air and its operating temperature generally reaches 300℃~400℃, it is easy to oxidize, thus affecting its service life.

First embodiment

FIG1 is a schematic cross-sectional view of the heat-not-burn smoking device of the first embodiment of the present application. As shown in FIG1 , the heat-not-burn smoking device includes a heating component 1, which is used to heat an atomizable material (not shown) to make the atomizable material produce smoke; the atomizable material is, for example, tobacco material, herbal material, or other material that can be heated to produce aerosol. The heating component 1 includes a container 11 and a carbon fiber heating element 12 disposed in the container 11. The carbon fiber heating element 12 can generate heat (i.e., emit heat) and emit infrared waves after being powered on to heat the atomizable material. The carbon fiber heating element 12 heats the atomizable material in at least one of the following ways:

Method 1: The infrared waves emitted by the carbon fiber heating element 12 are directly radiated onto the atomizable material to heat the atomizable material (i.e., radiation heating);

Method 2: The heat emitted by the carbon fiber heating element 12 is conducted to the container 11, and the container 11 is in thermal contact with the atomizable material to heat the atomizable material (ie, contact heating);

Method three: The heat and infrared waves emitted by the carbon fiber heating element 12 heat the air around the container 11 (including the heat and infrared waves emitted by the carbon fiber heating element 12 directly heating the air, and the heat and infrared waves emitted by the carbon fiber heating element 12 first heating the container 11, and then the container 11 heats the air around it), and the heated air is used to heat the atomizable material (i.e., indirect air heating).

The heating component 1 provided in the embodiment of the present application adopts a carbon fiber heating element 12 as a heating component. Carbon fiber is a black body material with an electrothermal conversion efficiency of up to 98%. It heats up quickly and the carbon fiber will not corrode the current when it is heated. At the same time, the carbon fiber can emit infrared waves when it is heated and has the function of radiation heating. Therefore, the carbon fiber heating element 12 can not only heat the atomizable material by heat conduction, but also can perform radiation heating on the atomizable material, and has the advantages of high heating efficiency and good heating uniformity.

As shown in FIG1 , as an embodiment, a sealed cavity 110 is provided in the container 11, and the sealed cavity 110 is a vacuum cavity (vacuum means a gas state lower than one atmospheric pressure in a given space, that is, a rarefied gas space with a pressure in a given space less than 101.325 kilopascals (kPa)) or has a protective gas for protecting the carbon fiber heating element 12, and the carbon fiber heating element 12 is arranged in the sealed cavity 110; the protective gas is, for example, nitrogen or argon, but is not limited to this.

Specifically, since carbon fiber will oxidize when heated in air, it will lose weight significantly when heated in air at 400°C, and its strength will be greatly reduced. Moreover, when the oxidation weight loss reaches 2-5%, the mechanical properties of the carbon fiber will decrease by 40%-50%, and its diameter will decrease. Therefore, it is necessary to perform anti-oxidation treatment on the carbon fiber heating element 12. The present application provides a sealed cavity 110 in the housing 11. The sealed cavity 110 is a vacuum cavity or has a protective gas to protect the carbon fiber heating element 12. This can effectively prevent the carbon fiber heating element 12 from being oxidized and extend the service life of the carbon fiber heating element 12.

As an implementation method, the sealed cavity 110 is a vacuum cavity, and the initial pressure in the sealed cavity 110 (i.e., the pressure in the sealed cavity 110 before the carbon fiber heating element 12 is heated) is a negative pressure, and the initial pressure in the sealed cavity 110 is -0.7atm to 0atm, preferably -0.7atm, -0.5atm, -0.2atm or 0atm, where atm is 1 standard atmospheric pressure unit. In this embodiment, since the sealed cavity 110 is a closed cavity, when the carbon fiber heating element 12 works at a high temperature, the container 11 expands due to heat, which causes the gas in the sealed cavity 110 to expand due to heat, resulting in an increase in internal pressure, thereby causing the sealed environment in the sealed cavity 110 to be destroyed by the expansion of the gas and fail, which is manifested as cracks or explosions in the container 11; on this basis, the pressure change of the air in the sealed cavity 110 as the temperature rises is calculated;

According to the ideal gas state equation: ,get ;

in, is the pressure ( ), is the gas volume ( ), is the temperature (K), is the amount of substance in the gas ( ), is the molar gas constant (8.31 J/( )）, is a constant value; since it is an ideal gas expansion in the sealed cavity 110, the gas volume in the sealed cavity 110 The molar mass of the gas in the closed cavity remains unchanged. unchanged, the molar gas constant is a constant, so is a constant, so When the gas temperature T in the sealed cavity 110 increases, the pressure (i.e., gas pressure) in the sealed cavity 110 also increases.

When the carbon fiber heating element 12 is not working, the gas in the sealed cavity 110 is at normal temperature and pressure, that is, , （ is 1 standard atmospheric pressure unit). At this time, the gas pressure in the sealed cavity 110 changes with temperature as shown in the following table: (the sealed cavity in the table refers to the sealed cavity 110)

Gas temperature in closed chamber ℃ Gas temperature in closed cavity K Absolute pressure of gas in closed cavity Pa The relative atmospheric pressure of the gas in the closed cavity Pa Relative atmospheric pressure of gas in closed cavity atm 20 293.15 101325 0 0.000 100 373.15 128976 27651 0.273 200 473.15 163541 62216 0.614 300 573.15 198105 96780 0.955 400 673.15 232669 131344 1.296 500 773.15 267233 165908 1.637 600 873.15 301797 200472 1.979

When the carbon fiber heating element 12 is not working, the gas in the sealed cavity 110 is at room temperature, and the gas in the sealed cavity 110 can be set to a negative pressure environment, that is, , (atm is 1 standard atmospheric pressure unit). At this time, the change of the gas pressure in the sealed cavity 110 with the temperature is as shown in the following table:

Gas temperature in closed chamber ℃ Gas temperature in closed cavity K Absolute pressure of gas in closed cavity Pa The relative atmospheric pressure of the gas in the closed cavity Pa Relative atmospheric pressure of gas in closed cavity atm 20 293.15 50663 -50662 -0.500 100 373.15 64488 -36836 -0.364 200 473.15 81770 -19554 -0.193 300 573.15 99052 -2272 -0.022 400 673.15 116335 15009 0.148 500 773.15 133617 32291 0.319 600 873.15 150899 49573 0.489

When the carbon fiber heating element 12 is working, the gas temperature in the sealed cavity 110 can reach 600°C. At this time, the gas in the sealed cavity 110 expands due to the increased temperature, which can easily cause the sealing failure of the container 11, and then cause the gas in the sealed cavity 110 to exchange with the gas outside the sealed cavity 110, thereby destroying the negative pressure environment of the sealed cavity 110, causing the carbon fiber heating element 12 to oxidize and reduce its reliability performance; when the carbon fiber heating element 12 is working, the gas temperature in the sealed cavity 110 is in the range of 200-400°C for a long time. When the heating component 1 is assembled, the initial pressure in the sealed cavity 110 is preferably set to -0.5atm. At this time, even if the heating component 1 works for a long time, the gas pressure in the sealed cavity 110 can basically reach a balance with the external atmospheric pressure, making the sealing effect more reliable.

Third embodiment

Fig. 3 is a schematic cross-sectional view of the heat-not-burn smoking device of the third embodiment of the present application, and Fig. 4 is a schematic view of the structure of the carbon fiber heating element in Fig. 3. As shown in Figs. 3 and 4, the heat-not-burn smoking device of this embodiment has substantially the same structure as the heat-not-burn smoking device of the first embodiment, and the main difference lies in the different structure of the carbon fiber heating element 12.

As shown in FIG. 3 and FIG. 4 , as an implementation mode, the carbon fiber heating element 12 is a mesh structure, and the carbon fiber heating element 12 is disposed on the outer wall of the heat conducting pipe 112 .

Specifically, the carbon fiber heating element 12 has a first electrode connection area 12A, a heating area 12B, and a second electrode connection area 12C connected in sequence along a first direction Y. The carbon fiber heating element 12 includes carbon fiber filaments 121, elastic filaments 122, first conductive filaments 123, and second conductive filaments 124. There are multiple carbon fiber filaments 121 and they extend along the first direction Y and are arranged in the first electrode connection area 12A, the heating area 12B, and the second electrode connection area 12C. The multiple carbon fiber filaments 121 are arranged at intervals along the second direction, and the second direction is perpendicular to the first direction Y; the elastic filaments 122 are arranged in the heating area 12B, the first conductive filaments 123 are arranged in the first electrode connection area 12A, and the second conductive filaments 124 are arranged in the second electrode connection area 12C. The elastic filaments 122, the first conductive filaments 123, and the second conductive filaments 124 are all interwoven and connected with the carbon fiber filaments 121.

As shown in FIG. 3 and FIG. 4 , as an embodiment, there are multiple elastic threads 122 extending along the second direction X, and the multiple elastic threads 122 are arranged at intervals along the first direction Y in the heating area 12B, and each elastic thread 122 and each carbon fiber thread 121 are interwoven up and down to form a first mesh structure;

There are a plurality of first conductive threads 123 extending along the second direction X. The plurality of first conductive threads 123 are spaced apart in the first electrode connection region 12A along the first direction Y. The first conductive threads 123 and the carbon fiber threads 121 are interwoven vertically to form a second mesh structure.

There are multiple second conductive threads 124 extending along the second direction X. The multiple second conductive threads 124 are spaced apart along the first direction Y in the second electrode connection region 12C. The second conductive threads 124 and the carbon fiber threads 121 are interwoven vertically to form a third mesh structure.

Specifically, the first mesh structure mainly plays a role of heating, the second mesh structure is mainly used to connect to one of the positive and negative electrodes of the power component 7, and the third mesh structure is mainly used to connect to the other of the positive and negative electrodes of the power component 7. Specifically, the power component 7 can be connected to the first conductive wire 123 in the second mesh structure and the second conductive wire 124 in the third mesh structure by welding through wires (not shown), so as to achieve electrical connection.

It should be noted that, taking the elastic wire 122 and the carbon fiber wire 121 as an example, the upper and lower interweaving specifically means that an elastic wire 122 contacts two surfaces located in relative positions at two adjacent carbon fiber wires 121. When the carbon fiber heating element 12 is sleeved on the heat pipe 112, the elastic wire 122 contacts one of the two adjacent carbon fiber wires 121 on the side away from the outer wall of the heat pipe 112, and the elastic wire 122 contacts the other of the two adjacent carbon fiber wires 121 on the side close to the outer wall of the heat pipe 112 (that is, the two sides of the elastic wire 122 contact the carbon fiber wire 121 and the heat pipe 112 at the same time). The elastic wire 122 forms a staggered contact with the opposite sides of the carbon fiber wire 121 during the interweaving process, which can be better woven into one. It can be understood that each elastic wire 122, the first conductive wire 123 and the second conductive wire 124 can be woven with the carbon fiber wire 121 by winding each carbon fiber wire 121 one circle or more in sequence.

In the present embodiment, the carbon fiber filaments 121 are electrically connected with the first conductive filaments 123 and the second conductive filaments 124 by interweaving them up and down. When the carbon fiber heating element 12 is welded with the conductive wires, it is sufficient to weld the conductive wires with the first conductive wires 123 and the second conductive wires 124, thereby avoiding the problem that the carbon fiber filaments 121 themselves are difficult to weld. In other words, the carbon fiber heating element 12 provided in the present embodiment uses the carbon fiber filaments 121 as the main body for heat generation and radiation, and achieves electrical connection with the first conductive wires 123 and the second conductive wires 124 by interweaving them, thereby solving the problem that the carbon fiber filaments 121 are difficult to weld with metal wires to achieve electrical connection.

As shown in Figures 3 and 4, as an embodiment, the carbon fiber heating element 12 is rolled into a tubular structure. Since the elastic wire 122 is added to the carbon fiber wire 121 for mixed weaving, the carbon fiber heating element 12 can be sleeved on the outside of the heat pipe 112 of various shapes, and has good conformability; when the carbon fiber heating element 12 is rolled into a tubular structure, the above-mentioned first direction Y can be the axial direction of the carbon fiber heating element 12, and the above-mentioned second direction X can be the circumferential direction of the carbon fiber heating element 12. Of course, the carbon fiber heating element 12 can also be a rectangular sheet structure, and the specific shape of the carbon fiber heating element 12 is not limited and will not be repeated here. When the carbon fiber heating element 12 is a rectangular sheet structure, one of the above-mentioned first direction Y and the second direction X is the length direction of the carbon fiber heating element 12, and the other is the width direction of the carbon fiber heating element 12.

As an embodiment, the carbon fiber filament 121 may be a T300 unidirectional filament, and the diameter of the carbon fiber filament 121 may be 36 to 150 μm. It should be noted that those skilled in the art may set the diameter of the carbon fiber filament 121 to 36 μm, 40 μm, 42 μm, 46 μm, 50 μm, 54 μm, 58 μm, 66 μm, 70 μm, 74 μm, 80 μm, 90 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, etc. according to actual needs, and no sole limitation is made here.

As an embodiment, the distance between two adjacent elastic threads 122 is 3-20 mm. It should be noted that those skilled in the art can set the distance between two adjacent elastic threads 122 to 3 mm, 5 mm, 7 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, etc. according to actual needs, and this is not a sole limitation.

As an implementation manner, the material of the elastic thread 122 can be organic cotton, aramid, nylon, polypropylene, polybutylene terephthalate or polyphenylene sulfate.

As an implementation mode, the width of the first electrode connection area 12A and the second electrode connection area 12C along the first direction Y can be 3-8 mm. It should be noted that those skilled in the art can set the width of the first electrode connection area 12A along the first direction Y to 4 mm, 5 mm, 6 mm, 7 mm, etc., and the width of the second electrode connection area 12C along the first direction Y to 4 mm, 5 mm, 6 mm, 7 mm, etc. according to actual conditions, and no sole limitation is made here.

As an implementation method, the resistance value of the carbon fiber heating element 12 can be 0.3~2Ω.

As an embodiment, the first conductive wire 123 can be a gold wire, a silver wire, a copper wire, an aluminum wire or a platinum wire. It is understood that the second conductive wire 124 can also be a gold wire, a silver wire, a copper wire, an aluminum wire or a platinum wire. The first conductive wire 123 and the second conductive wire 124 can be made of the same or different materials.

As shown in FIG3 , the difference between this embodiment and the first embodiment also includes: the cavity formed between the outer tube 111 and the heat conducting tube 112 in this embodiment is not a sealed cavity, but an open cavity connected to the external environment (of course, the cavity formed between the outer tube 111 and the heat conducting tube 112 can also be set as a sealed cavity); at the same time, the power supply component 7 in this embodiment is fixedly arranged on the outer wall of the outer tube 111. The shell of the heat-not-burn smoking device in this embodiment is not shown.

When the atomizable material is inserted into the heating channel 1120, the infrared waves generated by the carbon fiber heating element 12 pass through the radiation-transmitting pipe wall 1122, or pass through the heat pipe wall 1121 and the radiation-transmitting pipe wall 1122 to radiate to the atomizable material, and at the same time, the heated heat pipe wall 1121 conducts heat to the atomizable material.

The first conical segment 111B and the second conical segment 111C are respectively connected to opposite ends of the heat conducting tube 112.

As an implementation manner, the ratio of the area of the radiation-transmitting tube wall 1122 to the area of the heat-conducting tube wall 1121 is 1/3 to 2/3.

As an implementation manner, the material of the heat-conducting tube wall 1121 is aluminum nitride; the material of the radiation-transmitting tube wall 1122 is one of silicon nitride, microcrystalline glass, and quartz tube.
