一种烟气量充足的气溶胶产生制品An aerosol-generating product with sufficient smoke volume

技术领域technical field

本发明涉及烟草行业的加热不燃烧烟草制品技术领域，具体涉及一种烟气量充足的气溶胶产生制品。The invention relates to the technical field of heat-not-burn tobacco products in the tobacco industry, in particular to an aerosol generating product with sufficient smoke volume.

背景技术Background technique

现有的加热不燃烧电子烟在加热时都需要使用特制的烟具，该烟具带有一个插入到烟支内部进行加热的加热体；通常情况下，市场上通配的烟具中的加热的长度为2cm左右，这就使得烟支结构中用于产生气溶胶的功能段的长度必须与之匹配，否则多出的长度部分则无法被加热，这对于需要充足的烟气抽吸量的用户来说，显然是不理想的。Existing heat-not-burn electronic cigarettes need to use a special smoking set when heating. The smoking set has a heating body inserted into the inside of the cigarette for heating; usually, the length of the heating in the common smoking set on the market is About 2cm, which makes the length of the functional section used to generate aerosol in the cigarette structure must match it, otherwise the extra length part cannot be heated, which is for users who need sufficient smoke suction , which is obviously not ideal.

同时，当采用颗粒状的气溶胶产生基材时，加热体插入的过程中，颗粒状的气溶胶产生基材容易掉落到加热器中损坏加热器，现有技术中，为了解决颗粒状气溶胶产生基材掉落的问题而选择在加热体插入的一端设置封口片材以阻止掉落。另一方面，由于颗粒容易滚动，在装填颗粒状的气溶胶产生基材之前首先需要在纸管中装填一个阻隔件来阻止其滚动。采用封口片材的形式使得整个烟支生产的成本明显增加，而采用阻隔件的方式不但导致生产成本增加，还会使烟支的整体吸阻增大，使得消费者无法抽吸到足量被加热的烟气。At the same time, when the granular aerosol is used to generate the substrate, the granular aerosol generated substrate is easy to fall into the heater and damage the heater during the insertion of the heating body. In the prior art, in order to solve the problem of granular aerosol The sol produces the problem of the base material falling, so a sealing sheet is set at the end where the heating body is inserted to prevent the falling. On the other hand, since the particles are easy to roll, it is first necessary to fill the paper tube with a barrier to prevent it from rolling before filling the granular aerosol generating substrate. The use of the sealing sheet significantly increases the production cost of the entire cigarette, while the use of barriers not only increases the production cost, but also increases the overall suction resistance of the cigarette, making it impossible for consumers to smoke a sufficient amount of cigarettes. Heated flue gas.

例如现有技术CN108433197A或CN109043654A公开了一种加热不燃烧香烟及其组件，第一成型纸包裹烟草段形成烟支，第二成型纸包裹第一过滤段和第二过滤段形成复合滤棒，接装纸将烟支和复合滤棒卷接在一起。但其是针对烟丝或梗丝才需要的包裹，且吸阻大，烟草段容易变形或损伤。例如现有技术CN112244351A、CN113662239A、CN214179111U、CN112120281A等。如何在使用颗粒状发烟材料的同时解决掉落和滚动的问题而不增加成本和吸阻，同时能够提供充足的烟气量，这是摆在加热不燃烧烟草领域的一个难题。For example, the prior art CN108433197A or CN109043654A discloses a heat-not-burn cigarette and its components. The first forming paper wraps the tobacco section to form a cigarette, and the second forming paper wraps the first filter section and the second filter section to form a composite filter rod. Paper is used to wrap cigarettes and composite filter rods together. However, it is only required for shredded tobacco or shredded stems, and has a large suction resistance, and the tobacco segment is easily deformed or damaged. For example the prior art CN112244351A, CN113662239A, CN214179111U, CN112120281A etc. How to solve the problems of falling and rolling while using granular smoking materials without increasing cost and drawing resistance, and at the same time provide sufficient smoke volume is a difficult problem in the field of heat-not-burn tobacco.

本发明的一种烟气量充足的气溶胶产生制品，与现有技术相比，具有如下有益效果：An aerosol-generating product with sufficient smoke volume of the present invention has the following beneficial effects compared with the prior art:

(1)本发明将颗粒状的气溶胶产生基质通过包裹袋包裹后再通过白乳胶胶合(粘贴)在纸管内壁上，通过无纺布材质的单一的包裹袋将颗粒状的气溶胶产生基质完全地包装成圆柱状的发烟条状，再将该发烟条装填到纸管中，发烟条的左端面与纸管左端面齐平，纸管的右端面与过滤嘴的右端面齐平；此种结构一方面将气溶胶产生基质严密包裹，在加热体插入本发明的气溶胶产生制品时，包裹袋会阻止颗粒状的气溶胶产生基质掉落，从而解决掉落的问题；另一方面，气溶胶产生基质在装填到纸管时是包裹在包裹袋中的，包裹袋可以限制气溶胶产生基质的滚动，故装填过程中颗粒状的气溶胶产生基质不会发生滚动，从而节约了设置阻隔件的成本，使得纸管内的吸阻进一步降低，提升了用户满意度。本发明的发烟条通过白乳胶粘贴在纸管内壁上，从而确保了发烟条在加热体插入的过程中不会发生移动或变形，使得产品的结构进一步得到了优化和提升。(1) In the present invention, the granular aerosol-generating matrix is wrapped by a wrapping bag and then glued (pasted) on the inner wall of the paper tube by white latex, and the granular aerosol-generating matrix is produced by a single wrapping bag of non-woven material Completely pack into a cylindrical smoking rod, and then fill the smoking rod into a paper tube, the left end of the smoking rod is flush with the left end of the paper tube, and the right end of the paper tube is flush with the right end of the filter On the one hand, this structure tightly wraps the aerosol-generating matrix, and when the heating body is inserted into the aerosol-generating product of the present invention, the wrapping bag will prevent the granular aerosol-generating matrix from falling, thereby solving the problem of falling; on the other hand On the one hand, the aerosol-generating matrix is wrapped in a wrapping bag when it is filled into the paper tube, and the wrapping bag can limit the rolling of the aerosol-generating matrix, so the granular aerosol-generating matrix will not roll during the filling process, thereby saving The cost of installing the barrier further reduces the suction resistance in the paper tube, improving user satisfaction. The smoking rod of the present invention is pasted on the inner wall of the paper tube through white latex, thereby ensuring that the smoking rod does not move or deform during the insertion of the heating body, and further optimizes and improves the structure of the product.

(2)本发明的包裹袋的长度为35mm，故装填在其中的气溶胶产生基质的长度为35mm，相较于现有技术中的烟具中的加热体，该气溶胶产生基质存在约15mm的死角无法被加热体加热；但是，本发明中在包裹袋内增加了加热延长片，正是由于加热延长片的存在，使得传统烟具中的加热体除了加热20mm长度的气溶胶产生基质外，还能够通过该加热延长片将热量传递到无法被加热体加热的死角中进一步对其中的气溶胶产生基质进行加热；在同等直径的情况下，本发明的气溶胶产生基质的长度更长，因而能产生充足的烟气量供使用者抽吸，从而满足需要充足的烟气抽吸量的用户的抽吸需求。(2) The length of the wrapping bag of the present invention is 35 mm, so the length of the aerosol generating substrate filled therein is 35 mm. Compared with the heating body in the smoking set in the prior art, the aerosol generating substrate has a gap of about 15 mm. The dead corner cannot be heated by the heating body; however, in the present invention, a heating extension piece is added in the wrapping bag. It is precisely because of the existence of the heating extension piece that the heating body in the traditional smoking set not only heats the aerosol-generating substrate with a length of 20 mm, but also The heating extension piece can transfer heat to the dead corner that cannot be heated by the heating body to further heat the aerosol-generating substrate therein; under the condition of the same diameter, the length of the aerosol-generating substrate of the present invention is longer, so it can A sufficient volume of smoke is generated for the user to inhale, thereby satisfying the suction needs of the user who needs a sufficient amount of smoke to be sucked.

(3)本发明还设有第一中空段和第二中空段，第一中空段的纸管壁上开设冷却进气孔，该冷却进气孔的作用是在抽吸过程中补入空气以降低气溶胶产生制品所产生的烟气的温度；第二中空段内装填载香颗粒可以进一步改善气溶胶产生基质所产生的烟气的口感，提升用户使用体验。当载香颗粒装填好后，其可能会在第一中空段和第二中空段之间通过烟气通道往复运动，此种情况并不影响其发挥功效。本发明通过设置圆台状/锥台状的降温元件，使得气溶胶产生基质所产生的烟气在经过降温元件时进一步被冷却，此时降温元件相当于一个文丘里管，降温效果尤为明显，以确保使用者抽吸时不会有烫嘴的感觉。(3) The present invention is also provided with the first hollow section and the second hollow section, and the paper tube wall of the first hollow section offers a cooling air inlet, and the effect of the cooling air inlet is to fill in air during the suction process to Lowering the temperature of the smoke generated by the aerosol-generating product; filling the second hollow section with flavor-loaded particles can further improve the taste of the smoke generated by the aerosol-generating substrate and enhance user experience. After the fragrance-carrying particles are filled, they may reciprocate between the first hollow section and the second hollow section through the smoke channel, which does not affect their function. In the present invention, by setting a truncated conical/conical cooling element, the flue gas generated by the aerosol generating substrate is further cooled when passing through the cooling element. At this time, the cooling element is equivalent to a Venturi tube, and the cooling effect is particularly obvious. Make sure that the user does not have a burning sensation when inhaling.

(4)本发明通过将加热延长片设置成“M”形，一方面可以使得该加热延长片的覆盖面积增加，从而提高其热传递的效率，另一方面便于设置接合口，防止加热体在插入到气溶胶产生制品时被加热延长片阻挡从而发生弯折；也能够避免加热体推动加热延长片戳破包裹袋造成气溶胶产生基质的泄漏。(4) In the present invention, by setting the heating extension sheet into an "M" shape, on the one hand, the coverage area of the heating extension sheet can be increased, thereby improving the efficiency of heat transfer, and on the other hand, it is convenient to set the joint to prevent the heating body from When inserted into the aerosol-generating product, it is blocked by the heating extension piece to cause bending; it can also prevent the heating body from pushing the heating extension piece to puncture the wrapping bag and cause leakage of the aerosol-generating substrate.

(2)装填时，先将制备成型的加热延长片12装进包裹袋中，并确保其中轴线与包裹袋的中轴线重合，然后将气溶胶产生基质装填到包裹袋中，并通过无纺布材质的单一的包裹袋5将颗粒状的气溶胶产生基质完全地包装成圆柱状的发烟条状，装填密实后封口；在封口后的包裹袋的外壁上涂上白乳胶后迅速将其推入到纸管中装填，并确保包裹袋的端头与纸管端面平齐；(2) When filling, first put the preparedheating extension piece 12 into the wrapping bag, and ensure that the central axis coincides with the central axis of the wrapping bag, then fill the aerosol-generating matrix into the wrapping bag, and pass the non-woven fabric Thesingle wrapping bag 5 of material completely packs the granular aerosol generating matrix into a cylindrical smoking strip, and seals it after filling it tightly; after the outer wall of the sealed wrapping bag is coated with white latex, it is pushed quickly.

When the flue gas enters the second cavity, it mixes with the aroma components volatilized on the incense-carrying particles, and is mixed with the tube wall of the second hollow section. After further heat exchange, the temperature of the flue gas drops to a temperature that can be sucked; at this time, the flue gas enters the filter to filter out harmful impurities and is sucked by the user.

本发明的一种用于产生供抽吸烟气的装置，与现有技术相比，具有如下有益效果：A device for generating smoke for smoking of the present invention has the following beneficial effects compared with the prior art:

(1)本发明将颗粒状的气溶胶产生基质通过包裹袋包裹后再通过白乳胶胶合(粘贴)在纸管内壁上，通过无纺布材质的单一的包裹袋将颗粒状的气溶胶产生基质完全地包装成圆柱状的发烟条状，再将该发烟条装填到纸管中，发烟条的左端面与纸管左端面齐平，纸管的右端面与过滤嘴的右端面齐平；此种结构一方面将气溶胶产生基质严密包裹，在加热体插入本发明的气溶胶产生制品时，包裹袋会阻止颗粒状的气溶胶产生基质掉落，从而解决掉落的问题；另一方面，气溶胶产生基质在装填到纸管时是包裹在包裹袋中的，包裹袋可以限制气溶胶产生基质的滚动，故装填过程中颗粒状的气溶胶产生基质不会发生滚动，从而节约了设置阻隔件的成本，使得纸管内的吸阻进一步降低，提升了用户满意度。本发明的发烟条通过白乳胶粘贴在纸管内壁上，从而确保了发烟条在加热体插入的过程中不会发生移动或变形，使得产品的结构进一步得到了优化和提升。(1) In the present invention, the granular aerosol-generating matrix is wrapped by a wrapping bag and then glued (pasted) on the inner wall of the paper tube by white latex, and the granular aerosol-generating matrix is produced by a single wrapping bag of non-woven material Completely pack into a cylindrical smoking rod, and then fill the smoking rod into a paper tube, the left end of the smoking rod is flush with the left end of the paper tube, and the right end of the paper tube is flush with the right end of the filter On the one hand, this structure tightly wraps the aerosol-generating matrix, and when the heating body is inserted into the aerosol-generating product of the present invention, the wrapping bag will prevent the granular aerosol-generating matrix from falling, thereby solving the problem of falling; on the other hand On the one hand, the aerosol-generating matrix is wrapped in a wrapping bag when it is filled into the paper tube, and the wrapping bag can limit the rolling of the aerosol-generating matrix, so the granular aerosol-generating matrix will not roll during the filling process, thereby saving The cost of installing the barrier further reduces the suction resistance in the paper tube, improving user satisfaction.

After the fragrance-carrying particles are filled, they may reciprocate between the first hollow section and the second hollow section through the smoke channel, which does not affect their function. In the present invention, by setting a truncated conical/conical cooling element, the flue gas generated by the aerosol generating substrate is further cooled when passing through the cooling element. At this time, the cooling element is equivalent to a Venturi tube, and the cooling effect is particularly obvious. Make sure that the user does not have a burning sensation when inhaling.

(4)本发明通过将加热延长片设置成“M”形，一方面可以使得该加热延长片的覆盖面积增加，从而提高其热传递的效率，另一方面便于设置接合口，防止加热体在插入到气溶胶产生制品时被加热延长片阻挡从而发生弯折；也能够避免加热体推动加热延长片戳破包裹袋造成气溶胶产生基质的泄漏。(4) In the present invention, by setting the heating extension sheet into an "M" shape, on the one hand, the coverage area of the heating extension sheet can be increased, thereby improving the efficiency of heat transfer, and on the other hand, it is convenient to set the joint to prevent the heating body from When inserted into the aerosol-generating product, it is blocked by the heating extension piece to cause bending; it can also prevent the heating body from pushing the heating extension piece to puncture the wrapping bag and cause leakage of the aerosol-generating substrate.
