具有可移动式电连接发热体的低温烟具Low temperature smoking set with movable electric connection heating element

技术领域technical field

本发明属于吸烟用品技术领域，尤其涉及一种具有可移动式电连接发热体的低温烟具。The invention belongs to the technical field of smoking articles, and in particular relates to a low-temperature smoking article with a movable electric connection heating body.

背景技术Background technique

与传统的卷烟相比，加热不燃烧抽吸装置(又称低温烟具)直接加热烟草或烟碱制品，加热温度在220-250℃间，经烘烤后，烟气逐渐挥发出来，可以减少通过传统卷烟中烟草的燃烧和热降解产生有害烟气成分。Compared with traditional cigarettes, heat-not-burn smoking devices (also known as low-temperature smoking devices) directly heat tobacco or nicotine products, and the heating temperature is between 220-250 °C. The combustion and thermal degradation of tobacco in conventional cigarettes produces harmful smoke constituents.

从加热烟支的技术方面来讲，低温烟具分为中心加热和包围加热，中心加热是指以棒状或片状发热体插入到烟支中对其进行加热。对于传统的中心加热的低温烟具，其再将烟支插入到低温烟具中时，烟支会同步被中心加热烟具的发热体从烟支的一端刺进烟支内部，此过程需要使用者自己把握插入的力度，容易出现用力过猛导致烟支受损，或者用力不足使发热体没有完全进入到烟支内，导致烟支难以被充分加热。另外，发热体通过导线直接与电路板连接，并通过程序控制开启，发热体移动过程中存在断线的风险。From the technical aspect of heating cigarettes, low-temperature cigarettes are divided into central heating and surrounding heating. Central heating refers to inserting a rod-shaped or sheet-shaped heating element into the cigarette to heat it. For the traditional centrally heated low-temperature smoking set, when the cigarette is inserted into the low-temperature smoking set, the cigarette will be simultaneously pierced into the interior of the cigarette from one end of the cigarette by the heating element of the centrally heated smoking set. This process requires the user to grasp it by himself. The insertion force may cause the cigarette to be damaged due to excessive force, or the heating element does not fully enter the cigarette due to insufficient force, making it difficult for the cigarette to be fully heated. In addition, the heating body is directly connected to the circuit board through wires, and is turned on through program control, and there is a risk of disconnection during the movement of the heating body.

The second end is the insertion end of the heating element, and the housing 1 is also provided with alinear driving mechanism 6 that drives theheating element 2 to move. Thelinear driving mechanism 6 is electrically connected with the circuit board 3 to form a movement control circuit for controlling the movement of the heating element.

参见图1和图2，该低温烟具还包括串接在加热控制电路上发热体2和电路板3之间的第一触发件7和第二触发件8，第二触发件8固定安装在壳体1中，第一触发件7可随发热体2同步运动，当发热体2处于第一位置时，第一触发件7与第二触发件8相接触，实现加热控制电路的连通，当第一触发件7随发热体2朝第二位置运动时，第一触发件7与第二触发件8相分离，实现加热控制电路的断开。1 and 2, the low-temperature smoking device also includes afirst trigger member 7 and asecond trigger member 8 connected in series between theheating element 2 and the circuit board 3 on the heating control circuit, and thesecond trigger member 8 is fixedly installed on the shell In the body 1, thefirst trigger member 7 can move synchronously with theheating body 2.

When atrigger member 7 moves toward the second position with theheating body 2, thefirst trigger member 7 and thesecond trigger member 8 are separated to realize the disconnection of the heating control circuit.

参见图4和图5，本实施例低温烟具的工作过程如下：Referring to Figure 4 and Figure 5, the working process of the low-temperature smoking device of the present embodiment is as follows:

当用户需要抽吸时，将烟支9从第一端插入烟支插置腔5中，移动加热控制电路控制线性驱动机构6带动发热体2朝向第二端运动插入烟支插置腔5内并刺入烟支9中，当发热体2运动至第一位置时，控制电路控制线性驱动机构6停止运动；相应的，发热体2停止继续插入，与此同时，第一触发件7与第二触发件8相接触，使得加热控制电路连通，加热控制电路控制电源为发热体2供电，发热体2通电发热加热烟支内发烟材料，进而形成供用户抽吸的烟雾。When the user needs to smoke, thecigarette 9 is inserted into the cigarette insertion cavity 5 from the first end, and the moving heating control circuit controls thelinear drive mechanism 6 to drive theheating element 2 to move toward the second end and insert it into the cigarette insertion cavity 5 And pierce into thecigarette 9, when theheating element 2 moves to the first position, the control circuit controls thelinear drive mechanism 6 to stop moving; correspondingly, theheating element 2 stops and continues to be inserted, and at the same time, thefirst trigger 7 and the The twotriggers 8 are in contact, so that the heating control circuit is connected, the heating control circuit controls the power supply to supply power to theheating body 2, and theheating body 2 is energized to generate heat to heat the smoking material in the cigarette, thereby forming smoke for the user to draw.

当用户抽吸完成后，加热控制电路控制线性驱动机构6带动发热体2反向移动，从烟支插置腔5内退出，与此同时，第一触发件7与第二触发件8相分离，加热控制电路的断开，发热体2停止发热。When the user finishes smoking, the heating control circuit controls thelinear drive mechanism 6 to drive theheating body 2 to move in the opposite direction and withdraw from the cigarette insertion cavity 5. At the same time, thefirst trigger member 7 and thesecond trigger member 8 are separated. , the heating control circuit is disconnected, and theheating element 2 stops heating.

本实施例低温烟具不仅很好的解决烟支在抽吸完后烟丝与发热体2的黏连问题，避免烟丝在发热体2上产生过多的残留，减轻清洗发热体的负担，同时可以有效防止发烟材料脱落在烟具内，此外通过发热体的带动控制第一触发件7和第二触发件8的分离和接触，即可实现加热控制电路的通断，加热控制电路的通断过程控制简单，有效降低了烟具的成本。The low-temperature smoking device of this embodiment not only solves the problem of adhesion between the shredded tobacco and theheating element 2 after smoking, but also avoids excessive residues of the shredded tobacco on theheating element 2, reduces the burden of cleaning the heating element, and can effectively To prevent the smoking material from falling off in the smoking device, in addition, the separation and contact of thefirst trigger member 7 and thesecond trigger member 8 are controlled by the driving of the heating body, so that the on-off of the heating control circuit can be realized, and the on-off process control of the heating control circuit can be realized. It is simple and effectively reduces the cost of smoking sets.

需要说明的是，在实际设计中，烟支9可以设计成滤嘴段901和烟草段902的两段式结构，烟草段中设有发烟材料，烟支9插入烟具时，滤嘴段901至少部分从壳体1中外露出，从而便于用户直接含住滤嘴段进行抽吸。当然，还可在滤嘴段901和烟草段902之间增设冷凝过渡段，通过冷凝过渡段对烟雾进行冷却降温，用户抽吸感好。It should be noted that, in the actual design, thecigarette 9 can be designed into a two-segment structure of afilter segment 901 and atobacco segment 902. The tobacco segment is provided with a smoking material. When thecigarette 9 is inserted into a smoking device, thefilter segment 901 At least part of it is exposed from the housing 1, so that it is convenient for the user to directly hold the filter segment for suction. Of course, a condensation transition section can also be added between thefilter section 901 and thetobacco section 902, and the smoke is cooled and cooled by the condensation transition section, so that the user has a good suction feeling.

至于烟具的整个气流通道，均可以采用现有结构，如本实施例中，在壳体1与烟支插装腔5之间设有进气通道(图中未示出)，外部空气经进气通道从第二端进入烟支插置腔5中并从烟草段底部进入烟支，最终从滤嘴段902流出。As for the entire airflow channel of the smoking device, the existing structure can be adopted. For example, in this embodiment, an air intake channel (not shown in the figure) is provided between the casing 1 and the cigarette insertion cavity 5, and the outside air passes through the air inlet. The air passage enters the cigarette insertion cavity 5 from the second end and enters the cigarette from the bottom of the tobacco section, and finally flows out from thefilter section 902 .

可以想到的是，发热体2安装在发热体基座10上，在发热体基座10上设有发热体电路板11，发热体2的连接电极两端焊接在发热体电路板11上，在发热体电路板11上对应每一连接电极均对应设有第一触发件7，将导线12一端焊接在发热体电路板11上，另一端与第一触发件7焊接，发热体电路板11将发热体2与第一触发件7电路连通。It is conceivable that theheating element 2 is installed on theheating element base 10, the heatingelement circuit board 11 is provided on theheating element base 10, and both ends of the connecting electrodes of theheating element 2 are welded on the heatingelement circuit board 11. The heatingbody circuit board 11 is provided with afirst trigger member 7 corresponding to each connection electrode. One end of thewire 12 is welded to the heatingbody circuit board 11, and the other end is welded to thefirst trigger member 7. The heatingbody circuit board 11 will Theheating element 2 is in circuit communication with thefirst trigger element 7 .

参见图6，在一实施例中，本实施例低温烟具，第一触发件7包括固定套701、电极销702以及弹性元件703，电极销702通过其上的配合部A匹配滑动安装在固定套701中且顶端从固定套701中伸出形成与第二触发件8接触的抵触部B，弹性元件703连接在固定套701与电极销702的内底面之间。具体的，弹性元件703可以采用螺旋弹簧或弹片等部件。Referring to FIG. 6 , in one embodiment, the low-temperature smoking device of this embodiment, thefirst trigger member 7 includes a fixingsleeve 701 , anelectrode pin 702 and anelastic element 703 , and theelectrode pin 702 is slidably installed on the fixing sleeve through the matching portion A on theelectrode pin 702 701 and the top end protrudes from the fixingsleeve 701 to form a contact portion B that contacts thesecond trigger member 8 , and theelastic element 703 is connected between the fixingsleeve 701 and the inner bottom surface of theelectrode pin 702 . Specifically, theelastic element 703 may adopt components such as a coil spring or an elastic sheet.

本实施例中，电极销702呈圆柱状同轴置于固定套701内部，通过限位环704与固定套701紧固，再通过置于固定套701与电极销702之间的弹性元件703，保证电极销702在固定套701内部实现位移，固定套702连接导线12，当电极销702接触通电后，加热控制电路的电流依次经过电极销702、弹性元件703、固定套701导线12以及发热体电路板11流至发热体2。上述结构的第一触发件7，因电极销702、弹性元件703、固定套701等零件处于串联状态，当通过的电流过大时，弹性元件703发热，阻抗升高，从而将导至有相当大的接触电阻从而拉低整个电路的功率。In this embodiment, theelectrode pin 702 is cylindrically placed inside the fixingsleeve 701 coaxially, and is fastened to the fixingsleeve 701 by thelimit ring 704, and then passes through theelastic element 703 placed between the fixingsleeve 701 and theelectrode pin 702, Ensure that theelectrode pin 702 is displaced inside the fixedsleeve 701, and the fixedsleeve 702 is connected to thewire 12. When theelectrode pin 702 is contacted and energized, the current of the heating control circuit sequentially passes through theelectrode pin 702, theelastic element 703, thewire 12 of the fixedsleeve 701 and the heating element. Thecircuit board 11 flows to theheating element 2 . In thefirst trigger 7 of the above structure, since the electrode pins 702, theelastic element 703, the fixingsleeve 701 and other parts are in a series state, when the passing current is too large, theelastic element 703 heats up and the impedance rises, which will lead to a considerable The large contact resistance thus pulls down the power of the entire circuit.

参见图7和图8，在另一实施例中，本实施例低温烟具，第一触发件7包括固定套701、电极销702以及弹性元件703，电极销702通过其上的配合部A匹配滑动安装在固定套701中且两端从固定套701内伸出，电极销702的其中一端成为与第二触发件8接触的抵触部B，另一端通过导线12连接至发热体电路板11，弹性元件703套设在电极销702外且连接在配合部A与固定套701的内底面之间。与上述实施例所不同是，本实施例中，电极销702的非连接导线端受到压缩达到设计行程内的压缩量并接通发热控制电路时，加热控制电路的电流依次经过电极销702、导线12流至发热体2，不经过弹性元件703，从而可以保证较大电流通过时，避免过大接触电阻拉低功率。Referring to FIGS. 7 and 8 , in another embodiment, the low-temperature smoking device of this embodiment, thefirst trigger 7 includes a fixingsleeve 701 , anelectrode pin 702 and anelastic element 703 , and theelectrode pin 702 matches and slides through the matching portion A thereon Installed in the fixedsleeve 701 and both ends protrude from the fixedsleeve 701, one end of theelectrode pin 702 becomes the contact part B that contacts thesecond trigger 8, and the other end is connected to the heatingbody circuit board 11 through thewire 12, elastic Theelement 703 is sleeved outside theelectrode pin 702 and connected between the matching portion A and the inner bottom surface of the fixingsleeve 701 . The difference from the above embodiment is that in this embodiment, when the non-connected wire ends of the electrode pins 702 are compressed to the compression amount within the designed stroke and the heating control circuit is turned on, the current of the heating control circuit passes through the electrode pins 702 and the wires in sequence. 12 flows to theheating element 2 without passing through theelastic element 703, so as to ensure that when a large current passes, it can avoid excessive contact resistance to pull down the power.

参见图1和图2，在一实施例中，线性驱动机构6包括驱动电机601、主动件602、扭力传递件603、螺杆604和螺母605，驱动电机601的输出轴与主动件602固定连接，扭力传递件603滑动套接在主动件601上以实现扭力传递，螺杆604的两端分别与发热体基座10和扭力传递件603固定连接，螺母605固定设置在壳体1内并套接在螺杆604上。1 and 2, in one embodiment, thelinear drive mechanism 6 includes adrive motor 601, a drivingmember 602, atorque transmission member 603, ascrew 604 and anut 605, and the output shaft of the drivingmotor 601 is fixedly connected to the drivingmember 602, Thetorque transmission member 603 is slidably sleeved on the drivingmember 601 to realize the torque transmission, the two ends of thescrew 604 are respectively fixedly connected with theheating element base 10 and thetorque transmission member 603, and thenut 605 is fixedly arranged in the housing 1 and sleeved on theheating element base 10 and thetorque transmission member 603. on thescrew 604.

当用户需要吸烟时，将烟支9匹配插入烟支插置腔5中，按下壳体1上的按键，驱动电机601开始转动，主动件602跟随驱动电机601的输出轴同步运动，将动力传输至扭力传递件603，进而带动螺杆604作螺旋上升运动，使得发热体2从烟支插装腔5的第二端插入烟支插装腔5中并刺入烟支9中，接着，电极销702与第二触发件8接触，弹性元件703压缩，电极销702向固定套701内回收，移动控制电路导通，电池4对发热体2供电，发热体2发热将烟支内的烟草材料加热以产生用户抽吸的烟雾；当用户抽吸完成后需要退烟时，移动控制电路控制驱动电机901反向旋转，带动发热体2从烟支中退出的过程中，电极销702复位，直至电极销702与第二触发件8完全分离，加热控制电路断开，发热体2停止发热。When the user needs to smoke, insert thecigarette 9 into the cigarette insertion cavity 5, press the button on the casing 1, the drivingmotor 601 starts to rotate, the drivingpart 602 moves synchronously with the output shaft of the drivingmotor 601, and the power It is transmitted to thetorque transmission member 603, and then drives thescrew 604 to make a spiral upward movement, so that theheating element 2 is inserted into the cigarette insertion cavity 5 from the second end of the cigarette insertion cavity 5 and penetrated into thecigarette 9. Then, the electrode Thepin 702 is in contact with thesecond trigger 8, theelastic element 703 is compressed, theelectrode pin 702 is recovered into the fixedsleeve 701, the movement control circuit is turned on, thebattery 4 supplies power to theheating element 2, and theheating element 2 generates heat to remove the tobacco material in the cigarette. Heating to generate the smoke drawn by the user; when the user needs to withdraw the smoke after smoking, the movement control circuit controls the drivingmotor 901 to rotate in the reverse direction, and in the process of driving theheating element 2 to withdraw from the cigarette, theelectrode pin 702 resets until Theelectrode pin 702 is completely separated from thesecond trigger element 8, the heating control circuit is disconnected, and theheating element 2 stops heating.

本实施例，发热体2从烟支9中退出时，烟支9因无法克服与烟支插置腔5之间的静摩擦力而处于静止状态，使得发热体2与烟支9中的烟丝脱离，同时粘连在发热体2上的烟丝在离心力作用下脱离发热体2，从发热体2甩脱分离的烟丝因自身具有一定的粘接力重新与烟支内的其余烟丝粘连而不会沉积在烟支插置腔5的底部。此外，在烟支9拔出之前，发热体2相对烟支作分离运动，相当于给与粘连的烟丝一个轴向脱离力，粘连的烟丝进一步脱离发热体，将烟支从低温烟具中拔出时，可以更加有效的防止发烟材料脱落在烟具内。In this embodiment, when theheating element 2 is withdrawn from thecigarette 9, thecigarette 9 is in a static state because it cannot overcome the static friction force between the cigarette and the cigarette insertion cavity 5, so that theheating element 2 is separated from the shredded tobacco in thecigarette 9. At the same time, the shredded tobacco adhered to theheating body 2 is separated from theheating body 2 under the action of centrifugal force, and the shredded tobacco thrown off and separated from theheating body 2 is re-adhesive with the remaining shredded tobacco in the cigarette because of its own certain adhesive force and will not be deposited on the cigarette. The cigarette is inserted into the bottom of the cavity 5 . In addition, before thecigarette 9 is pulled out, theheating element 2 performs a separation movement relative to the cigarette, which is equivalent to giving an axial detachment force to the adhered shredded tobacco. The adhered shredded tobacco is further separated from the heating element, and the cigarette is pulled out from the low temperature smoking set It can more effectively prevent the smoking material from falling off in the smoking set.

当然，线性驱动机构6也可以采用以下结构：包括固定安装在壳体中的驱动电机、与驱动电机的驱动轴固定连接的连接座和连接轴，连接轴的一端与发热体基座固定连接，另一端与连接座螺旋连接，连接轴上穿装有与其螺旋连接且与壳体固定连接的螺纹卡座。驱动电机带动连接座同步旋转，连接座带动连接轴作螺旋顶升运动，进而带动发热体插入烟支插装腔中。Of course, thelinear drive mechanism 6 can also adopt the following structure: including a drive motor fixedly installed in the housing, a connecting seat and a connecting shaft fixedly connected with the drive shaft of the drive motor, and one end of the connecting shaft is fixedly connected with the heating body base, The other end is screwed with the connecting seat, and the connecting shaft is threaded with a threaded clamping seat which is screwed with the connecting seat and is fixedly connected with the housing. The driving motor drives the connecting seat to rotate synchronously, and the connecting seat drives the connecting shaft to perform a screw jacking motion, thereby driving the heating body to be inserted into the cigarette insertion cavity.

参见图9，因上述结构的低温烟具，发热体2在烟具内的运动为螺旋升降运动，因而第一接触件7也是作螺旋升降运动，为保证第一接触件7旋转至任何位置时，均能实现与第二接触件8的接触，在壳体1中还固定设有连接板13，在连接板13上面向第一接触件7的端面上设有正对抵触部的环形触环，环形触环构成第二接触件8，环形触环的中心轴与发热体2旋转轴线重合，环形触环与烟具的电路板3导通，上述结构的第二接触件8，可以保证电极销702总在环形触环的某一点与电路板3实现电气连接，在连接过程中，电路板3保证位移距离实现电极销902与环形触环接触具备可靠稳定性。Referring to Fig. 9, due to the low-temperature smoking device of the above structure, the movement of theheating element 2 in the smoking device is a spiral up and down movement, so thefirst contact piece 7 also performs a spiral up and down movement, in order to ensure that when thefirst contact piece 7 rotates to any position, all Contact with thesecond contact piece 8 can be achieved. A connectingplate 13 is also fixedly arranged in the housing 1. On the end face of the connectingplate 13 facing thefirst contact piece 7, there is an annular contact ring facing the abutting part. The contact ring constitutes thesecond contact piece 8, the central axis of the annular contact ring coincides with the rotation axis of theheating element 2, and the annular contact ring is connected to the circuit board 3 of the smoking device. A certain point of the annular contact ring is electrically connected to the circuit board 3. During the connection process, the circuit board 3 ensures a displacement distance so that the contact between the electrode pins 902 and the annular contact ring has reliable stability.

因本实施例中，第一触发件7的数量为两个，因此在连接板13上设有两个同心排布的环形触环，每个环形触环都对应与一个发热体电极且每个环形触环对应连接一个电极销702。Because in this embodiment, the number of thefirst trigger members 7 is two, two concentrically arranged annular contact rings are provided on the connectingplate 13, each annular contact ring corresponds to a heating body electrode and each The annular contact ring is connected to oneelectrode pin 702 correspondingly.

对于本领域技术人员来说，线性驱动机构6还可以采用线性电机、液压缸或气动缸，这种形式的线性驱动机构6，发热体2仅仅只能在壳体1中作轴向移动，而不能作螺旋运动，发热体2在退烟时，与螺旋退烟的方式，此种方式退烟，发热体2上粘连的烟丝相对来说会多一点。For those skilled in the art, thelinear drive mechanism 6 can also use a linear motor, a hydraulic cylinder or a pneumatic cylinder. In this form of thelinear drive mechanism 6, theheating element 2 can only move axially in the housing 1, while The spiral motion cannot be performed. When theheating element 2 exits the smoke, it is the same as the spiral smoke exiting method. In this way, the shredded tobacco adhered to theheating element 2 will be relatively more.

为防止热量向壳体1传递，造成烫手等问题，在烟支插置腔5与壳体1之间还可以设置隔热构件(图中未示出)，该隔热构件可以选择真空管、隔热棉等现有结构，也可以直接设置成空气隔热。In order to prevent heat transfer to the casing 1, causing problems such as hot hands, a heat insulating member (not shown in the figure) can also be arranged between the cigarette insertion cavity 5 and the casing 1. Existing structures such as thermal cotton can also be directly set to be air-insulated.

为方便发热刺入烟支9，发热体2设计呈棒状且面向烟支插置腔第二端的前端设计成圆锥形，圆锥形的外周表面上形成有螺旋凸起(图中未示出)，为便于加工，螺旋凸起与圆锥形的外周表一体成型。采用该发热体加热的烟具，在完成抽烟后，发热体与螺旋旋转插入烟支时相反的方向螺旋旋转退出脱离烟支，相较于垂直直接退出脱离烟支，旋转退出的力臂更长更省力，并将导致加热附着在发热体上的烟草残留附着物更少。In order to facilitate heating to penetrate thecigarette 9, theheating element 2 is designed in a rod shape and the front end facing the second end of the cigarette insertion cavity is designed into a conical shape, and a spiral protrusion (not shown in the figure) is formed on the outer peripheral surface of the conical shape, For the convenience of processing, the spiral protrusion is integrally formed with the conical outer peripheral surface. Using the smoking article heated by the heating element, after the smoking is completed, the heating element rotates in the opposite direction to the spiral rotation when it is inserted into the cigarette and exits the cigarette. It saves effort and will result in less tobacco residue adhered to the heating element.
