Description

低温不燃烧烟具Low temperature non-burning smoking set 技术领域Technical field
本发明涉及烟具的技术领域,特别是涉及一种低温不燃烧烟具。The invention relates to the technical field of smoking articles, in particular to a low temperature non-burning smoking article.
背景技术Background technique
一般的低温不燃烧烟具采用加热不燃烧技术对烟草直接加热,加热过程中烟草不会燃烧产生烟雾。通过低温不燃烧烟具吸烟时既能获得吸食烟草的满足感,又可减少吸烟过程中有害物质的产生。The general low-temperature non-burning smoking article uses the heating non-combustion technology to directly heat the tobacco, and the tobacco does not burn to generate smoke during the heating process. By smoking at a low temperature, smoking can not only satisfy the satisfaction of smoking tobacco, but also reduce the generation of harmful substances during smoking.
低温不燃烧烟具内部一般开设有进气腔,进气腔用于引入空气。吸烟过程中,空气经由进气腔流入低温不燃烧烟具内,经加热后流入烟草中,再被吸入人体内。由于进气腔直接与环境空气接触,进气腔的内壁上易沉积灰尘、水汽、焦油与水汽混合物等,清洁难度大。The low temperature non-combustion smoking article is generally provided with an air inlet chamber for introducing air. During the smoking process, air flows into the low-temperature non-burning smoking article through the air inlet chamber, and after being heated, it flows into the tobacco and is then inhaled into the human body. Since the air inlet chamber is directly in contact with the ambient air, dust, water vapor, tar and water vapor mixture are easily deposited on the inner wall of the air inlet chamber, which is difficult to clean.

参考图1和图2,在一实施例中,低温不燃烧烟具10包括管口组件100、加热组件、套管300和底座400。同时参考图3和图4,管口组件100内开设有烟卷通道110和进气通道120,烟卷通道110与进气通道120连通,烟卷通道110用于插入烟卷20,且烟卷通道110的内径与烟卷20的外径相适配,进气通道120的延伸方向与烟卷20的延伸方向相同。加热组件200与管口组件100固定连接,加热组件200内开设有出气通道210,出气通道210与烟卷通道110连通,烟卷20能够穿过烟卷通道110并插入出气通道210内。当烟卷20收容于烟卷通道110内时,烟卷20的外壁能够将进气通道120与出气通道210隔开,即吸烟过程中,环境空气在烟卷20的外部的进气通道120内流动,烟卷20烘烤后产生的烟气混合物则在烟卷20的内部流动。套管300套设于加热组件200上并与管口组件100固定连接。套管300与加热组件200 围设成进气腔310,进气腔310分别与进气通道120和出气通道210连通。底座400分别与套管300和加热组件200固定连接,底座400用于封闭进气腔310,以使空气能够在低温不燃烧烟具10内流动。Referring to Figures 1 and 2, in one embodiment, the low temperature non-combustion smoking article 10 includes a spout assembly 100, a heating assembly, a sleeve 300, and a base 400. Referring to FIG. 3 and FIG. 4, the nozzle assembly 100 is provided with a cigarette passage 110 and an intake passage 120. The cigarette passage 110 is in communication with the intake passage 120, and the cigarette passage 110 is used for inserting the cigarette 20, and the inner diameter of the cigarette passage 110 is The outer diameter of the cigarette 20 is adapted, and the direction in which the intake passage 120 extends is the same as the direction in which the cigarette 20 extends. The heating assembly 200 is fixedly coupled to the nozzle assembly 100. The heating assembly 200 defines an outlet passage 210. The outlet passage 210 communicates with the cigarette passage 110, and the cigarette 20 can pass through the cigarette passage 110 and be inserted into the outlet passage 210. When the cigarette 20 is received in the cigarette channel 110, the outer wall of the cigarette 20 can separate the inlet passage 120 from the outlet passage 210, that is, the ambient air flows in the intake passage 120 outside the cigarette 20 during smoking, the cigarette 20 The smoke mixture produced after baking flows inside the cigarette 20. The sleeve 300 is sleeved on the heating assembly 200 and is fixedly coupled to the nozzle assembly 100. Casing 300 and heating assembly 200 Enclosed as an intake chamber 310, the intake chamber 310 is in communication with the intake passage 120 and the outlet passage 210, respectively. The base 400 is fixedly coupled to the sleeve 300 and the heating assembly 200, respectively, and the base 400 is used to close the intake chamber 310 to enable air to flow in the low temperature non-combustion smoking article 10.
上述低温不燃烧烟具10,烟卷20可以插入低温不燃烧烟具10的管口组件100的烟卷通道110内,并在加热组件200的出气通道210内进行烘烤。由于烟卷通道110的内径与烟卷20的外径相适配,烟卷20收容于烟卷通道110内时,烟卷20的外壁能够将进气通道120与出气通道210隔开,环境空气就可以由低温不燃烧烟具10的顶部进入,流经进气通道120,继而进入进气腔310内,并在烟具本体内被加热,对烟卷20进行烘烤。由于烟卷20内流通的是加热的空气,因此可以利用烟卷20外表面的热量对进气通道120内的环境空气进行加热,使得环境空气中的水汽和易挥发物质及时蒸发掉,以防止水汽和易挥发物质进入进气腔310内,从而能够有效保持进气腔310的干燥和清洁。The low temperature non-combustion smoking article 10, the cigarette 20 can be inserted into the cigarette channel 110 of the nozzle assembly 100 of the low temperature non-burning smoking article 10, and baked in the outlet passage 210 of the heating assembly 200. Since the inner diameter of the cigarette passage 110 is adapted to the outer diameter of the cigarette 20, when the cigarette 20 is received in the cigarette passage 110, the outer wall of the cigarette 20 can separate the inlet passage 120 from the outlet passage 210, and the ambient air can be kept from low temperature. The top of the combustion smoking article 10 enters, flows through the intake passage 120, then enters the intake chamber 310, and is heated within the body of the smoking article to bake the cigarette 20. Since the heated air is circulated in the cigarette 20, the ambient air in the intake passage 120 can be heated by the heat of the outer surface of the cigarette 20, so that the water vapor and the volatile matter in the ambient air are evaporated in time to prevent the water vapor and the water vapor. The volatile matter enters the intake chamber 310, thereby effectively maintaining the drying and cleaning of the intake chamber 310.
同时参考图5和图6,在一实施例中,加热组件200包括第一加热筒220和第二加热筒230,第一加热筒220和第二加热筒230均沿套管300的延伸方向延伸。第一加热筒220的一端与底座400固定连接,第一加热筒220的另一端与第二加热筒230的一端固定连接,第二加热筒230的另一端与管口组件100固定连接。在一实施实例中,第一加热筒220和第二加热筒230采用铆接方式固定连接,在保证第一加热筒220和第二加热筒230连接稳固的同时还有利于第一加热筒220和第二加热筒230的拆卸。出气通道210位于第二加热筒230内,烟卷20能够插入第二加热筒230内,且第二加热筒230能够加热烟卷20。套管300套设于第一加热筒220和第二加热筒230外,套管300、第一加热筒220和第二加热筒230共同围设成大致呈环形的进气腔310,环境空气可由进气通道120流入进气腔310内。第一加热筒220和第二加热筒230通电后可以发热,因此第一加热筒220和第二加热筒230能够加热进气腔310内的气体。通过使进气腔310内的空气与加热组件200直接接触,由进气通道120流入进气腔310内的空气能够进一步升温,进而使得空 气内的水汽和易挥发物质被进一步加热蒸发,以保证进气腔310的干燥和清洁。5 and FIG. 6, in an embodiment, the heating assembly 200 includes a first heating cylinder 220 and a second heating cylinder 230, and both the first heating cylinder 220 and the second heating cylinder 230 extend along the extending direction of the sleeve 300. . One end of the first heating cylinder 220 is fixedly connected to the base 400, the other end of the first heating cylinder 220 is fixedly connected to one end of the second heating cylinder 230, and the other end of the second heating cylinder 230 is fixedly connected to the nozzle assembly 100. In an embodiment, the first heating cylinder 220 and the second heating cylinder 230 are fixedly connected by riveting, and the first heating cylinder 220 and the second heating cylinder 220 and the second heating cylinder 230 are connected to be stable, and the first heating cylinder 220 and the first The disassembly of the two heating cylinders 230. The outlet passage 210 is located in the second heating cylinder 230, the cigarette 20 can be inserted into the second heating cylinder 230, and the second heating cylinder 230 can heat the cigarette 20. The sleeve 300 is sleeved outside the first heating cylinder 220 and the second heating cylinder 230. The sleeve 300, the first heating cylinder 220 and the second heating cylinder 230 are collectively arranged as a substantially annular inlet chamber 310, and the ambient air can be The intake passage 120 flows into the intake chamber 310. The first heating cylinder 220 and the second heating cylinder 230 may generate heat after being energized, and thus the first heating cylinder 220 and the second heating cylinder 230 can heat the gas in the intake chamber 310. By bringing the air in the intake chamber 310 into direct contact with the heating assembly 200, the air flowing into the intake chamber 310 from the intake passage 120 can be further heated, thereby making it empty. The water vapor and volatile matter in the gas are further heated and evaporated to ensure drying and cleaning of the intake chamber 310.
在一实施例中,第一加热筒220的材质为金属,第一加热筒220连接电源后即可发热,并对第一加热筒220内的空气进行加热。在另一实施例中,第一加热筒220的材质为发热陶瓷,发热陶瓷在接通电源后能够发热,并对第一加热筒220内的空气进行加热。在一实施例中,第二加热筒230的材质可以为金属或发热陶瓷,第二加热筒230接通电源后可以发热,此处不再赘述。第一加热筒220和第二加热筒230的区别在于,第一加热筒220是直接对环境空气进行加热,第二加热筒230内则用于插入烟卷20,以对流入烟卷20内的加热的空气进一步加热,使得烟卷20在第二加热筒230内进行烘烤。In one embodiment, the first heating cylinder 220 is made of metal. When the first heating cylinder 220 is connected to the power source, it can generate heat and heat the air in the first heating cylinder 220. In another embodiment, the material of the first heating cylinder 220 is a heat generating ceramic, and the heat generating ceramic can generate heat after the power is turned on, and heat the air in the first heating cylinder 220. In an embodiment, the material of the second heating cylinder 230 may be metal or heat-generating ceramics, and the second heating cylinder 230 may generate heat after being powered on, and details are not described herein. The first heating cylinder 220 and the second heating cylinder 230 are different in that the first heating cylinder 220 directly heats the ambient air, and the second heating cylinder 230 is used to insert the cigarette 20 to heat the inflow into the cigarette 20. The air is further heated so that the cigarette 20 is baked in the second heating cylinder 230.
在一实施例中,第一加热筒220内开设有加热腔221,加热腔221与出气通道210连通。底座400内开设有滞气腔410,滞气腔410分别与进气腔310和加热腔221连通,进气腔310内的气体能够通过滞气腔410流入第一加热筒220内。具体地,在一实施例中,第一加热筒220大致呈圆筒状,第一加热筒220的靠近底座400的底端开设有第一进气槽223,滞气腔410通过第一进气槽223与加热腔221连通,进气腔310内的气体可以经由第一进气槽223流入加热腔221内。滞气腔410的作用在于,其能够存储一定量的空气,作为气流的缓冲区域,使得气流能够缓慢地流入加热组件200内。滞气腔410还可作为异物的收容腔,若某些异物进入了进气腔310内,在进气腔310内未被蒸发,异物就会落入滞气腔410内。由于进气腔310内的气流在滞气腔410内需要改变方向才能流入加热室内,继而流入出气通道210内,且出气通道210的口径小于滞气腔410的口径,易出现出气通道210内气流的流速大于进气腔310内气流的流速的现象,即滞气腔410内易于产生负压,因此在滞气腔410内的异物易被搅动的气流浮起并进入加热组件200内。加热组件200内部的温度较高,异物进入加热组件200内部后,容易被蒸发并进入出气通道210内,最后粘附与烟草上。经过上述过程,水汽或异物很难在低温不燃烧烟具10内部沉积,因此能够有效地保证低温不燃烧烟具10的 内部的清洁,从而可以避免经常拆卸低温不燃烧烟具10以清洁低温不燃烧烟具10内部,进而节省了使用者的时间。In an embodiment, the first heating cylinder 220 is provided with a heating chamber 221, and the heating chamber 221 is in communication with the outlet passage 210. A gas venting chamber 410 is disposed in the base 400. The gas venting chamber 410 communicates with the air inlet chamber 310 and the heating chamber 221, respectively. The gas in the air inlet chamber 310 can flow into the first heating tube 220 through the stagnation chamber 410. Specifically, in an embodiment, the first heating cylinder 220 is substantially cylindrical, and the bottom end of the first heating cylinder 220 near the base 400 is provided with a first air inlet slot 223, and the air holding chamber 410 passes through the first air inlet. The groove 223 is in communication with the heating chamber 221, and the gas in the intake chamber 310 can flow into the heating chamber 221 via the first intake groove 223. The function of the stagnation chamber 410 is that it can store a certain amount of air as a buffer zone for the airflow so that the airflow can slowly flow into the heating assembly 200. The stagnant air chamber 410 can also serve as a receiving cavity for the foreign matter. If some foreign matter enters the air intake chamber 310, the air is not evaporated in the air inlet chamber 310, and the foreign matter falls into the air holding chamber 410. Since the airflow in the air inlet chamber 310 needs to change direction in the air stagnation chamber 410 to flow into the heating chamber, and then into the air outlet passage 210, and the diameter of the air outlet passage 210 is smaller than the diameter of the air venting chamber 410, the airflow in the air outlet passage 210 is likely to occur. The flow rate is greater than the flow rate of the airflow in the intake chamber 310, that is, the negative pressure is easily generated in the air stagnation chamber 410, so that the foreign matter in the stagnation chamber 410 is easily floated by the airflow and enters the heating assembly 200. The temperature inside the heating assembly 200 is relatively high, and after the foreign matter enters the interior of the heating assembly 200, it is easily evaporated and enters the outlet passage 210, and finally adheres to the tobacco. Through the above process, water vapor or foreign matter is difficult to deposit inside the low temperature non-burning smoking article 10, so that the low temperature non-burning smoking article 10 can be effectively ensured. The internal cleaning can avoid frequent disassembly of the low temperature non-burning smoking article 10 to clean the interior of the low temperature non-burning smoking article 10, thereby saving the user's time.
可以理解的是,为使第一加热筒220和第二加热筒230的加热温度能够可控,在第一加热筒220和第二加热筒230的筒壁上可以设置温度传感器,以实时检测第一加热筒220或第二加热筒230的温度,并可结合控制器和程序对第一加热筒220和第二加热筒230的加热电流或加热时间进行控制,以保证烘烤烟卷20的效率和质量。It can be understood that, in order to enable the heating temperature of the first heating cylinder 220 and the second heating cylinder 230 to be controllable, a temperature sensor can be disposed on the wall of the first heating cylinder 220 and the second heating cylinder 230 to detect in real time. The temperature of a heating cylinder 220 or a second heating cylinder 230, and the heating current or heating time of the first heating cylinder 220 and the second heating cylinder 230 may be controlled in conjunction with a controller and a program to ensure the efficiency of the baking tobacco 20 and quality.
在一实施例中,加热组件200还包括加热芯240和过滤片250,过滤片250卡设于第一加热筒220和第二加热筒230之间。加热芯240收容于加热腔221内,加热芯240的一端与第一加热筒220抵接,加热芯240的另一端与过滤片250抵接。加热芯240的外表面上开设有螺旋流道241,第一加热筒220上开设有贯穿第一加热筒220的内外表面的第二进气槽225,进气腔310通过第二进气槽225与螺旋流道241连通,进气腔310内的气体可由第二进气槽225流入加热腔221内,并在螺旋流道241内流动。过滤片250上开设有过滤孔251,螺旋流道241通过过滤孔251与出气通道210连通。在一实施例中,加热芯240大致呈圆柱状,加热芯240的外径与第一加热筒220的内径大致相等。当加热芯240与第一加热筒220组装后,由滞气腔410流入加热腔221内的气体能够与由进气腔310流入加热腔221内的气体混合,并沿加热芯240的螺旋流道241上升。In an embodiment, the heating assembly 200 further includes a heating core 240 and a filter sheet 250. The filter sheet 250 is interposed between the first heating cylinder 220 and the second heating cylinder 230. The heating core 240 is housed in the heating chamber 221, and one end of the heating core 240 abuts against the first heating cylinder 220, and the other end of the heating core 240 abuts against the filter sheet 250. A spiral flow path 241 is defined in the outer surface of the heating core 240. The first heating cylinder 220 is provided with a second air inlet groove 225 extending through the inner and outer surfaces of the first heating tube 220. The air inlet chamber 310 passes through the second air inlet slot 225. In communication with the spiral flow path 241, the gas in the intake chamber 310 can flow into the heating chamber 221 through the second intake groove 225 and flow in the spiral flow path 241. A filter hole 251 is opened in the filter sheet 250, and the spiral flow path 241 communicates with the air outlet passage 210 through the filter hole 251. In one embodiment, the heating core 240 is substantially cylindrical, and the outer diameter of the heating core 240 is substantially equal to the inner diameter of the first heating cylinder 220.

在一实施例中,加热芯240由发热陶瓷制成,加热芯240接通电源时能够发热,从而可以对加热芯240周围的空气进行加热,以提高加热空气的效 率。在其他实施方式中,加热芯240的材质也可以为金属,由金属材料制成的加热芯240从进气腔310内进入的空气在螺旋流道241内沿螺旋流道241缓慢上升,从而减缓了气流流速,使得气流能够与第一加热筒220充分接触,以使空气被充分加热至需要的温度。在一实施例中,过滤片250为圆片状,过滤孔251贯穿过滤片250的上下表面,且过滤孔251的数量为多个,通过设置多个过滤孔251,一方面有利于空气进入第二加热筒230内,另一方面通过过滤片250可以防止烟卷20在烘烤过程产生的颗粒物落入第二加热筒230内,造成螺旋流道241的堵塞。In an embodiment, the heating core 240 is made of a heat generating ceramic, and the heating core 240 can generate heat when the power is turned on, so that the air around the heating core 240 can be heated to improve the effect of heating the air. rate. In other embodiments, the material of the heating core 240 may also be metal. The air entering from the air inlet chamber 310 by the heating core 240 made of a metal material slowly rises along the spiral flow path 241 in the spiral flow path 241, thereby slowing down. The flow rate of the gas stream is such that the gas stream can be in sufficient contact with the first heating cylinder 220 to allow the air to be sufficiently heated to the desired temperature. In one embodiment, the filter sheet 250 has a disk shape, and the filter holes 251 extend through the upper and lower surfaces of the filter sheet 250, and the number of the filter holes 251 is plural.

The inner flow passage 243 functions to enable the air in the air stagnation chamber 410 to directly flow into the air outlet passage 210 via the heating core 240, but since the cross-sectional area of the inner flow passage 243 is suddenly reduced, the gas has a larger cross-sectional area. The flow velocity in the inner flow passage 243 of the small portion suddenly increases, thereby facilitating the formation of a negative pressure, so that gas or foreign matter in the stagnant gas chamber 410 is carried into the heating core 240 to utilize the heat in the heating core 240 to make the water vapor or The foreign matter is evaporated.
