Description

一种增强热交换效果的发烟装置Smoke generating device with enhanced heat exchange effect 技术领域Technical field
本发明属于新型卷烟烟具领域，具体涉及一种增强热交换效果的发烟装置。The invention belongs to the field of novel cigarette smoking appliances, and in particular relates to a smoking device with enhanced heat exchange effect.
背景技术Background technique
现有加热卷烟烟支由烟草段和滤棒两大部份组成，而滤棒又大多数都由靠近烟草段的支撑段、中部的降温段和消费者嘴唇接触的、末端的唇端三大部份组成。在加热卷烟烟支***现有对烟支加热的烟具中时，由于烟支的烟草段部份较短，多数仅为10～15mm，最多不会超过20mm，大多数烟具都需将烟草段和(或)滤棒的支撑段部份一起***烟具加热的腔体。此外，消费者在使用未针对某一品种(或品牌)烟支生产的通用型烟具时，会直接造成发热元件末端距离烟支滤棒的支撑段不足2mm，甚至已经深入到滤棒支撑段的头部的现象。在上述情况下，一旦对烟支进行正常加热抽吸时，就大概率会产生支撑段材料不耐受加热体高温而发生热缩或热塌陷现象。这不仅影响烟支后半段的抽吸(因支撑段热缩或热塌陷时，烟支变形或***)，还直接影响到烟支的吸味。Existing heated cigarettes are composed of two parts: a tobacco section and a filter rod, and most of the filter rods are composed of a support section near the tobacco section, a cooling section in the middle, and a lip at the end that is in contact with the consumer’s lips. Partial composition. When heating cigarettes are inserted into existing smoking devices that heat cigarettes, because the tobacco section of the cigarettes is relatively short, most of them are only 10-15mm, and no more than 20mm at most, most of the cigarettes need to be combined with the tobacco section. (Or) The supporting section of the filter rod is inserted into the heating cavity of the smoking device together. In addition, when consumers use general-purpose smoking utensils that are not produced for a certain variety (or brand) of cigarettes, they will directly cause the end of the heating element to be less than 2mm away from the support section of the cigarette filter rod, and even penetrate into the support section of the filter rod. Phenomenon of the head. Under the above circumstances, once the cigarette is normally heated and sucked, there is a high probability that the support section material cannot withstand the high temperature of the heating body and heat shrinkage or thermal collapse occurs. This not only affects the smoking of the second half of the cigarette (due to the heat shrinkage or thermal collapse of the support section, the cigarette deforms or becomes soft), but also directly affects the smoking taste of the cigarette.
申请人之前的设计了一种在折叠气道感应加热的发烟装置(申请号：2020110443853)通过设计了一种新型的烟支导入管减少烟具与烟支滤棒的接触面积以降低烟支滤棒上支撑段部份中材料的热缩现象。The applicant previously designed a smoking device with induction heating in the folded airway (application number: 2020110443853). By designing a new type of cigarette introduction tube to reduce the contact area between the smoking device and the cigarette filter rod to reduce the cigarette filter Heat shrinkage of the material in the supporting section of the rod.
本发明在上述专利(申请号：2020110443853)基础上进一步改进，期待进一步降低烟具对烟支滤棒上支撑段部份的热量传输，同时期待增强烟具的热交换效果，提高热量利用率。The present invention is further improved on the basis of the above-mentioned patent (application number: 2020110443853). It is expected to further reduce the heat transmission of the smoking set to the supporting section of the cigarette filter rod, and at the same time, it is expected to enhance the heat exchange effect of the smoking set and increase the heat utilization rate.
发明内容：Summary of the invention:
本发明仅对上述专利(申请号：2020110443853)的烟具烟支导入管1部分进行改进，烟具的其余零部件如加热部分等均与申请号：2020110443853专利相同。在此说明书中不再详细说明。The present invention only improves the first part of the smoking set and cigarette introduction tube of the above-mentioned patent (application number: 2020110443853), and the remaining parts of the smoking set, such as the heating part, are the same as the patent application number: 2020110443853.

为了使上导管1F和下导管1J联接配合紧密，对于圆柱形台优选导热性能差，热阻大的无机耐高温粘合剂联接，当然也可以用传统的螺钉联接，对锥形台则可利用锥体的自锁兼定位功能固定。In order to make the upper duct 1F and the lower duct 1J tightly connected, an inorganic high-temperature resistant adhesive with poor thermal conductivity and large thermal resistance is preferred for the cylindrical table. Of course, it can also be connected by traditional screws, and the conical table can be used. The self-locking and positioning function of the cone is fixed.
所述上导管1F下端部和下导管1J上端部通过上下适配的定位配合台1H实现两者定位配合，或者所述上导管1F下端部一部分和下导管1J上端部一部分共同形成定位配合台1H。The lower end of the upper duct 1F and the upper end of the lower duct 1J are positioned and matched by a positioning and matching platform 1H that is adapted up and down, or a part of the lower end of the upper duct 1F and a part of the upper end of the lower duct 1J together form a positioning and matching platform 1H .
优选地，当所述定位配合台1H的形状为圆柱形台时，所述上导管1F下端部包括阶梯状圆台，所述下导管1J上端部包括与其匹配的阶梯状圆台，两者共同形成定位配合台1H。Preferably, when the positioning and matching platform 1H is a cylindrical platform, the lower end of the upper duct 1F includes a stepped truncated cone, and the upper end of the down duct 1J includes a stepped truncated cone matching it, and the two together form a positioning Cooperate with Taiwan 1H.

隔热垫的目的：隔热垫对所述上导管1F和下导管1J做相对隔热处理，使得从下导管1J传来的感应加热的热量更多地仅集中在下导管1J上，只有相对少的部份通过定位配合台1H和热阻相对较大的隔热垫，才能传到上导管1F中，因 此形成上导管1F的温度要稍低于下导管1J的温度。而上导管1F上的第一导入孔1B也仅是圆环的一部分须除去用于进气的多个导气槽1C对应的弧长，故与烟支滤棒中支撑段有直接接触的圆弧更少了，所以可以起到减少自烟具下部发热部份传来的热量，于是滤棒的支撑段部份受热收缩的现象可以比较明显的改善。The purpose of the heat insulation pad: The heat insulation pad performs relatively heat insulation treatment on the upper duct 1F and the lower duct 1J, so that the heat of induction heating from the lower duct 1J is more concentrated on the lower duct 1J, and only relatively less The part can be transferred to the upper duct 1F through the positioning and matching platform 1H and the thermal insulation pad with relatively large thermal resistance. Therefore, the temperature forming the upper duct 1F is slightly lower than the temperature of the lower duct 1J. The first introduction hole 1B on the upper duct 1F is only a part of the ring. The arc length corresponding to the multiple air guide grooves 1C for air intake must be removed, so there is a circle that directly contacts the support section of the cigarette filter rod. There are fewer arcs, so it can reduce the heat transferred from the lower part of the smoking device, so the phenomenon of heat shrinkage of the support section of the filter rod can be significantly improved.

外界空气在所述混气腔1D内的流通路径和热交换过程如下：The circulation path and heat exchange process of outside air in the air mixing chamber 1D are as follows:
当烟支***发烟装置抽吸时，外界空气从分布在第一导入孔1B周向的导气槽1C进入与烟支外壁的空隙之间，进入到混气腔1D底部的同时，外界常温空气对发烟装置的已加热抽吸的烟支滤棒的外壁进行相对冷却。这部份空气再通过所述第一导气管1M下端部与所述混气腔1D之间的气流通道进入所述第一导气管1M和所述第二导气管1N之间的空隙中、然后向上流动到所述第二导气管1N上端部与所述混气腔1D之间的气流通道，再向下通过所述第二导气管1N外壁与所述混气腔1D内壁之间的气流通道进入进气道1A。When the cigarette is inserted into the smoking device and sucked, the outside air enters the gap between the outer wall of the cigarette and the air guide groove 1C distributed in the circumferential direction of the first introduction hole 1B, and enters the bottom of the air mixing chamber 1D at the same time. The air relatively cools the outer wall of the heated and sucked cigarette filter rod of the smoking device. This part of air then enters the gap between the first air duct 1M and the second air duct 1N through the airflow channel between the lower end of the first air duct 1M and the air mixing chamber 1D, and then Flow upwards to the airflow channel between the upper end of the second air duct 1N and the air mixing chamber 1D, and then downwards through the airflow channel between the outer wall of the second air duct 1N and the inner wall of the air mixing chamber 1D Enter the intake port 1A.
此过程中，气流在所述混气腔1D内折返多次，发烟装置内部传导过来的热量通过上导管1F和下导管1J对穿流混气腔1D的常温空气进行热交换，直到这些流经的空气也在吸烟者的抽吸负压作用下，通过进气道1A将初步加热的空气(经发热元件6所在的气流通道)最后送入烟支容纳腔。During this process, the air flow is folded back in the air mixing chamber 1D many times, and the heat conducted from the inside of the smoking device exchanges heat with the room temperature air flowing through the air mixing chamber 1D through the upper duct 1F and the lower duct 1J, until these flows The passing air is also under the suction negative pressure of the smoker, and the preliminarily heated air (via the airflow channel where the heating element 6 is located) is finally sent into the cigarette accommodating cavity through the air inlet 1A.
与此同时，所述第一导气管1M和所述第二导气管1N也将从与其接触的烟支导入管1和发热元件的热辐射上获得最大的热量，当循环至此的空气穿行在所述第一导气管1M和所述第二导气管1N周围时，也对空气进行加热。At the same time, the first air guide tube 1M and the second air guide tube 1N will also obtain the maximum heat from the heat radiation of the cigarette introduction tube 1 and the heating element that are in contact with them. When surrounding the first air duct 1M and the second air duct 1N, the air is also heated.
本发明的另外一种设计方案是：将所述第二导气管1N替换为以过盈配合方式安装***所述进气道1A的环状分布的多个进气针1L。Another design solution of the present invention is to replace the second air duct 1N with a plurality of annularly distributed air intake needles 1L installed in the air intake passage 1A in an interference fit manner.
所述进气针1L上端部进气孔与所述烟支导入管1内壁之间存在空隙，作为气流通道。There is a gap between the air inlet hole at the upper end of the air inlet needle 1L and the inner wall of the cigarette introduction tube 1 as an air flow channel.
空气通过进气针1L内部的小孔将初步加热的空气送入加热腔，与此同时， 从进气道1A端部***的进气针1L也将从其下部的下导管1J的发热元件的热辐射和下导管1J上获得最大的热量，当循环至此的空气穿行其中时，也将发生对空气的加热。The air passes through the small holes inside the intake needle 1L to send the preliminarily heated air into the heating chamber. At the same time, the intake needle 1L inserted from the end of the intake duct 1A will also remove the heating element from the downcomer 1J at its lower part. The heat radiation and the downcomer 1J obtain the greatest amount of heat, and when the circulating air passes through it, heating of the air will also occur.
所述进气针1L内孔直径为0.1～0.9mm。The diameter of the inner hole of the air intake needle 1L is 0.1-0.9 mm.
优选的，所述进气针1L的上端部孔口为倾斜端面。这可以加速进气速率。也能防止安装时意外堵塞。Preferably, the upper end hole of the air intake needle 1L is an inclined end surface. This can accelerate the intake rate. It can also prevent accidental blockage during installation.
上述技术方案在不矛盾的前提下，可自由组合。The above technical solutions can be freely combined without contradiction.
本发明具有以下有益效果：The present invention has the following beneficial effects:
1、本发明设计了一种增强热交换效果的发烟装置，烟支导入管设计为上下可分离的部分，隔热垫对所述上导管和下导管做相对隔热处理，进一步起到了隔热作用，减少了下部加热杯和发热元件的热量向上部的传递。因此，与烟支滤棒接触的上导入管温度较低，极大减少与发烟装置烟支导入管接触的烟支滤棒支撑段材料不耐受加热体高温而发生热缩或热塌陷现象。1. The present invention designs a smoking device that enhances the heat exchange effect. The cigarette introduction pipe is designed as a part that can be separated from the top and bottom. The heat insulation pad performs relative heat insulation treatment on the upper duct and the lower duct, which further isolates the upper and lower ducts. The heat effect reduces the heat transfer from the lower heating cup and the heating element to the upper part. Therefore, the temperature of the upper inlet tube in contact with the cigarette filter is lower, which greatly reduces the material of the support section of the cigarette filter rod in contact with the cigarette inlet tube of the smoking device. .
2、优选的技术方案中，本发明在烟支导入管内部设计了引导空气循环的第一导气管1M和第二导气管1N，空气在混气腔1D内可以进行多次往返，以更充分地进行热交换。外界空气对烟支导入管部分起到降温作用，烟支导入管和发热元件对空气起到预热作用。2. In the preferred technical solution, the present invention designs a first air guide tube 1M and a second air guide tube 1N that guide air circulation inside the cigarette introduction tube, and the air can go back and forth multiple times in the air mixing chamber 1D to make it more adequate. Ground heat exchange. The outside air cools the part of the cigarette introduction pipe, and the cigarette introduction pipe and the heating element preheat the air.
