实施例一
如图3所示,加热主体100(见图1)包括外壳120、加热组件和隔热组件。加热组件包括上盖130、基座140和加热元件150,外壳120的一端缩径形成折弯部121,折弯部121围合成插烟口101(见图1),折弯部121的一端连接有上盖130,加热元件150的一端插设在上盖130中,加热元件150的另一端与基座140连接。加热主体100还包括设置在加热元件150外侧的隔热组件,隔热组件包括上隔热座310、下隔热座320和隔热件330,上隔热座310设置在上盖130内,下隔热座320与基座140相连,隔热件330设置在上隔热座310和下隔热座320之间。在本实施例中,为了增强隔热效果,隔热件330包括第一隔热元件331、第二隔热元件332和第三隔热元件333。上盖130上设置有用于允许烟支插入的第四通孔(未图示)、第一安装凹位131和第二安装凹位132。由于图中第四通孔的位置被烟支遮挡,故未示出,但是从图中烟支穿过上盖130可知上盖130上设有第四通孔。第一安装凹位131靠近所述第四通孔,用于插设加热元件150的一端。第二安装凹位132与第一安装凹位131相邻,用于安装上隔热座310,图中由于上隔热座310与第二安装凹位132位置重叠,故将二者的位置标记在同一处。基座140包括第三通孔141、第一安装台阶142和第三安装凹位143,加热元件150的另一端套设在第一安装台阶142上。上隔热座310朝向下隔热座320的一侧在沿远离加热元件150的方向上依次设置有第一安装槽(未图示)、第二安装槽(未图示)和第三安装槽(未图示),下隔热座320朝向上隔热座310的一侧在沿远离加热元件150的方向上对应地依次设置有第五安装槽(未图示)、第六安装槽(未图示)和第七安装槽(未图示)。第一隔热元件331的两端分别安装在第一安装槽和第四安装槽内,第二隔热元件332的两端分别安装在第二安装槽和第五安装槽内,第三隔热元件333的两端分别安装在第三安装槽和第六安装槽内。由于上述安装槽的位置被各隔热元件遮挡,故未标出,从各隔热元件的端部设置在上隔热座310和下隔热座320的位置可以看出上述安装槽的相应位置。下隔热座320背离上隔热座310的一侧设置有安装凸起321和连接凹槽322,安装凸起321与基座140上的第三安装凹位143相配适,以完成基座140和下隔热座320之间的稳固连接。由于安装凸起321和第三安装凹位143的位置重合,故将二者标注在同一处。
所述固定组件220包括顶盖221和底座222;所述顶盖221的一端与所述加热主体100(见图1)相连,顶盖221的一端与隔热组件相连,所述顶盖221与远离所述隔热组件的一侧上连接有所述预热件230,所述预热件230远离所述顶盖221的一端上连接有底座222。具体地,顶盖221的一端设置有连接凸起2211,连接凸起2211与下隔热座320上的连接凹槽322相配适,以完成预热组件200和隔热组件之间的物理连接,进而完成加热主体100之间的物理连接,由于连接凸起2211和连接凹槽322的位置重叠,故将二者标记在同一处。
在本实施例中,所述预热件230为镂空的管状预热件,所述顶盖221的整个内腔为预热腔210。在本实施例中,预热件230的结构与加热元件150的结构相同,方便加工及装配。
顶盖221设置有第一通孔2215(详见图9),顶盖221朝向所述底座222的方向凸起形成第一凸起2212,所述第一通孔2215贯穿所述第一凸起2212,所述预热件230的一端套设在所述第一凸起2212外;所述底座222设置有第二通孔2221,所述底座222朝向顶盖221的方向凸起形成第二凸起2222,所述第二通孔2221贯穿所述第二凸起2222,所述预热件230的另一端套设在所述第二凸起2222外,使得预热件230可以加热整个预热腔210内的空气。底座底座所述顶盖221的侧壁上设置有进气孔2213,所述底座222的侧壁上设置有通气孔2223,所述进气孔2213、所述通气孔2223和预热腔210相连通。
在本实施例中,预热件230的内腔中设置有有分流组件500,即预热腔210内还设置有分流组件500。分流组件500的外壁与预热件230的内壁紧密贴合,使得预热件230的温度可以更快速均匀地传递到分流组件500中,加热分流组件500。分流组件500上设置有若干个沿着所述预热件230的轴向分布的分流孔510,分流孔510将空气分成了若干个细小气流,从而更容易被加热。分流组件500由导热材料制成,如,金属或者陶瓷等。预热件230发热后,将热量传导到分流组件500中,加热分流组件500,从而加热分流孔510中的细小气流。图3中的箭头示出了本实施例中的空气流动方向,即从进气孔2213进气,流向通气孔2223,然后进入分流孔510中,对空气进行分流和充分加热,然后再到达加热主体100(见图1)中,从而实现对将要进入加热主体100内的空气进行预加热的目的。在分流组件500中还可以放置香精香料,可以改善香烟口感,或者在分流件内放置活性炭等过滤材料,过滤异味。
所述分流组件500(见图3)包括第一分流件520和连接在所述第一分流件520的一端的第二分流件530,第一分流件520和第二分流件530中均设置有相对应设置的分流孔510(见图3)。第一分流件520的一端套设在第一通孔2215(详见图9)内,第一分流件520的另一端与第二分流件530的一端相连,第二分流件530的另一端套设在第二通孔2221内。
请结合图3,参见图4,所述第一分流件520的外周面上设置有第一限位凸起521,第一凸起2212远离顶盖221的一端抵持在所述第一限位凸起521上;所述第二分流件531的外周面上设置有第二限位凸起531,所述第二凸起2222远离所述底座222的一端抵持在所述第二限位凸起531上。通过设置第一限位凸起521和第二限位凸起531,避免在组装时,对分流件的压力过大,挤压过度导致分流件弯曲或者变形,影响分流孔510的形状,导致进气不畅。为了避免第一分流件520和第二分流件530之间的连接处有缝隙,导致漏气,所述分流组件500还包括用于连接所述第一分流件520和第二分流件530的连接件540,所述连接件540套设在所述第一分流件520和第二分流件530的外侧,所述连接件540的两端分别抵持在所述第一限位凸起521远离所述第一凸起2212的一侧和所述第二限位凸起531远离所述第二凸起2222的一侧上。第一分流件520和第二分流件530也可以直接以套设连接、过盈配合连接或者一体成型等连接方式连接,而不需要其他连接件540。
如图5所示,图5为本发明提供的烤烟装置的控制电路示意图。
烤烟装置还包括与预热件230和加热元件150电连接的控制电路600,用于分别控制所述加热主体100和所述预热组件200进行加热。
控制电路600有两种实施方案,第一种为加热主体100和所述预热组件200同时发热。如图6所示,在这种方案中,控制电路600包括电源(未示出);启动单元610,用于发送启动信号;处理单元620,与所述启动单元610相连,用于接受所述启动信号,并根据所述启动信号控制所述加热元件150和预热件320进行同时加热。在这一方案中,启动单元610可以为开关或气流传感器。
如图7所示,由于预热件230(见图3)需要先对分流组件500(见图2)进行加热,再有分流组件500对分流孔510(见图3)中的细小气流进行加热,为防止预热件230和加热元件150同时启动,分流组件500尚未被完全加热,在电路启动初期达不到预热空气的效果,因此,另一种控制电路600的设计中,预热件230和加热元件150不同时加热,加热存在先后顺序。优选地,预热件230先对流入烤烟装置的空气进行预热,然后再启动加热元件150加热。控制电路600包括第一启动单元611,用于控制预热件230对从烤烟装置外流入烤烟装置内的空气进行预热;第二启动单元612,用于在预热件230对流入烤烟装置内的空气进行预热后,发送第二启动信号;处理单元620,与所述所述第二启动单元612相连,用于接受所述第二启动信号,并根据所述第二启动信号控制所述加热主体100进行加热。
图8为本实施例一优选的控制电路图。
如图8所示,第一启动单元611为开关S0,设置在外壳120(见图3)的外侧壁上;第二启动单元612为气流传感器,设置在顶盖221(见图3)靠近进气孔2213(见图3)的内侧壁上;控制单元620也设置在顶盖221(见图3)的内侧壁上;电源可以为与烤烟装置相连的电池组件也可以为外接电源,通过导线与控制单元620、预热件230和加热元件150相连。电源的正极与开关S0的一端相连,开关S0的另一端与预热件230的一端相连,预热件230的另一端与电源的负极相连,当打开开关S0时,预热件230开始发热,对分流组件500进行加热。开关S0的另一端还与气流传感器的第1端连接,气流传感器的第2端与控制单元620的一端连接,气流传感器的第3端与电源的负极相连。控制单元620的另一端与加热元件150的一端相连,加热元件150的另一端与电源的负极相连。当位于进气孔2213旁的气流传感器感应到进气气流后,将第二启动信号发送给处理单元620,处理单元620才控制加热元件150加热。当开关S0断开时,即使有气流流经进气孔2213,气流传感器在开关S0未接通的断电情况下,也无法向处理单元620发送第二启动信号,故加热元件150无法启动。该控制电路实现了预热件230的先启动,加热元件150的后启动,用户可以根据自己需要的预热时间和预热温度控制吸气的时间,启动加热元件150加热烟支,吸食烟雾。。但是,在此实施例中,预热件230的预热时间和预热温度无法保证,不善于控制预热时间和预热温度的用户有可能在开关S0开启时马上吸烟,这样可能造成分流组件500还未被完全加热,降低了空气的预热效果。
图9为本实施例另一优选的控制电路图
如图9所示,在本实施例中处理单元620包括微控制器和场效应晶体管(MOS管),第一启动单元611为开关S0,第二启动单元612为温度传感器T。开关S0的一端和电源正极连接,另一端分别和预热件230、MOS管源极和微控制器连接,MOS的漏极D和加热元件150的一端连接,栅极G和微控制器连接,微控制器还和与预热件230相邻的温度传感器T的一端连接,温度传感器T的另一端接地,加热元件150和预热件230的另一端均和电源负极连接,电源的负极还分别与微控制器、预热件230和加热元件150连接。在本电路图中,在微处理器中植入对应的程序,通过该程序,MOS管可以执行对应的工作。上述对应的程序为,当温度传感器T传递来的温度信号低于微处理器中的预设温度值的时候,微控制器控制MOS管断开;当温度传感器T传递来的温度信号高于微处理器中的预设温度值的时候,微控制器控制MOS管导通。开关S0开启后,预热件230发热,但是此时,MOS管尚未导通,因此,加热元件150尚未通电,无法发热。与预热件230相邻的温度传感器T将感应到的温度信号传递到微控制器,当温度超过预设温度时,如50℃,微控制器控制MOS管导通以接通加热元件150的电源,使加热元件150发热。该控制电路保证了预热件230的温度,保证了空气的预热效果。可以理解地,还可以将温度传感器T换成计时器,通过保证预热件230的预热时间来保证空气的预热效果。
上述微控制器和MOS管设置在顶盖221(见图3)的内侧壁上,温度传感器T设置在分流组件500(见图3)中,开关S0设置在外壳120(见图3)的外侧壁上,电源通过导线与微控制器、MOS管、预热件230和加热元件150相连接。优选地,还可以在外壳120(见图3)的外侧壁上设置指示灯,当达到预设温度时,微控制器控制指示灯亮起,提示用户预热完成。
实施例二
实施例二与实施例一的不同之处有以下几点:一、实施例二中没有设置分流组件500,二、底座222的结构不同,三、进气通路的设置方式不同。
如图10所示,在本实施例中,底座222还连接在顶盖221的一端上。在本实施例中,底座222套设在顶盖221的一端上,并与顶盖221过盈配合。顶盖221上设置有第一通孔2215,顶盖221朝向底座222的方向凸起形成第一凸起2212,第一通孔2215贯穿所述第一凸起2212;预热件230的一端套设在第一凸起2212上;底座222朝向顶盖221的方向凸起形成第二凸台2224,预热件230的另一端套设在所述第二凸台2224外,所述第二凸台2224延伸入所述预热件230的内腔内,所述第二凸台2224的外侧壁与所述预热件230的内壁之间形成分流通道511。
顶盖221的侧壁上设置有进气孔2213,进气孔2213与镂空的管状加热件的镂空部分和预热腔210相连通。进气通路如本图9中的箭头所示,烤烟装置外的空气通过进气孔2213进入到烤烟装置内,然后通过镂空的管状加热件的镂空部分进入到分流通道511内,进而进入到加热组件100中。
实施例三
实施例三与实施例一的不同之处在于预热组件200的结构。
如图11所示,预热组件200还包括预套设在所述预热件230外的预热套管231,预热套管231的内腔为所述预热腔210;顶盖221远离所述隔热组件的一侧上连接有所述预热套管231,所述预热套管231远离所述顶盖221的一端上连接有底座222。具体地,顶盖221上设置有第一通孔2215,所述顶盖221朝向所述底座222的方向凸起形成第一凸起2212,第一通孔2215贯穿第一凸起2212;预热套管231的一端套设在第一凸起2212上;底座222设置有第二通孔2221,底座3222朝向顶盖221的方向凸起形成第二凸起2222,第二通孔2221贯穿所述第二凸起2222,预热套管231的另一端套设在第二凸起2222上。
预热件230为盘旋抵持在所述预热套管231的内壁上的电热丝,其可以固定设置在预热套管231的内壁上,可以可拆卸地紧密贴合在所述预热套管的内壁上。在该实施例中,其他结构与实施例一相同,在此不再赘述。
实施例四
实施例四与实施例三的不同之处在于预热件230的结构。
如图12所示,所述预热件230为设置在所述预热套管231内壁上的镂空预热片或预热网,所述镂空预热片或预热网与所述预热套管231的轴向呈第一角度。优选地,所述第一角度为90度,即,镂空预热片或预热网垂直与所述预热套管231的轴向设置。该镂空预热片和预热网的数量可以为多个,在本实施例中为三个。
如图13所示,本发明涉及一种烤烟装置的烟草预热方法,包括以下步骤:
S100、发送启动信号;
S200、接收所述启动信号,并根据所述启动信号控制预热件230和加热元件150进行同时加热。
如图14所示,本发明另一实施例中还涉及一种烤烟装置的烟草预热方法,包括以下步骤:
S100、控制所述预热件230对从烤烟装置外流入烤烟装置内的空气进行加热;
S200、在所述预热件230开始加热后,发送第二启动信号;
S300、根据所述第二启动信号控制所述加热元件150进行加热。
结合图9参见图15,步骤S200进一步包括:
S210、通过与预热件230相邻的温度传感器T将感应到的温度信号传递到微控制器;
S220、当温度超过预设温度时,微控制器控制MOS管导通以接通加热元件150的电源,使加热元件150发热。
综上所述,本发明提供的烤烟装置能对将要进入加热主体的空气进行预热,提高空气温度,避免冷空气带走加热区域的热量,使加热温度降低,从而有利于蒸出烟草中的烟气。同时防止烟气遇冷凝结,导致口感损失或打湿烟草,从而提升烟气口感。第三,预热件和加热元件零件完全相同,方便加工及装配。第四,分流件内放置香精香料,可以改善香烟口感,或者在分流件内放置活性炭等过滤材料,过滤异味。
以上所述仅为本发明的较佳实施例,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
