背景技术
低温加热不燃烧作为新型雾化方式相较于传统燃烧雾化所产生有害物有大大的减少,因此近些年在国内外被用户所接受,而目前市面上加热不燃烧雾化大多采用的是类似加热体和雾化装置一体,而杆状雾化介质为一次性使用,但是在使用过程中还是存在一些问题,如插入式加热方式加热片上容易积碳脏污,加热片容易折断,不好清理。
而在杆状雾化介质外加热的方式存在着发热体和杆状雾化介质接触不好,受热不均匀,而且大多存在的问题是加热体和杆状雾化介质接触面小,发热体的热量传导到杆状雾化介质上速度较慢,而且靠近发热体的位置被烤焦而离发热体远的位置未被加热到,因此利用率低,用户等待时间长,因此需要做一些改进,来解决上述问题。

本发明的最佳实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本发明的具体实施方式。
如图1至3所示,本发明一个优选实施例中的气溶胶形成单元10包括由雾化组件11a卷绕形成的雾化单元11、在雾化单元11一端设置的过滤嘴12、在雾化单元11远离过滤嘴12的一端设置的过滤片13、以及包覆在雾化单元11和过滤嘴12外的支撑筒14,过滤嘴12部分主要和人体接触、过滤杂质和大颗粒以及降温,使得进入嘴部的烟气温度适中,过滤片13的作用可以防止一些大颗粒灰尘等物质进入,同时可以防止烟丝烟草等从气溶胶形成单元10内漏出来。
结合图4所示,支撑筒14可以将雾化单元11和过滤嘴12连接在一起,优选地,支撑筒14为卷设的支撑纸,支撑纸可以使得气溶胶形成单元10有一定的硬度,一是可以使得气溶胶形成单元10能顺利的插入到加热器20,还有就是可以支撑住雾化单元11,让雾化单元11的电极113得到定位,使得加热器20上弹性接触触点211和气溶胶形成单元10上的电极113接触良好。
结合图5、6所示,雾化组件11a包括固体气溶胶形成基质111、加热体112、电极113,固体气溶胶形成基质111为柔性片状,优选地,可以将草本植物的提取纤维,制成柔性可折弯的纸状或者片状固体气溶胶形成基质111,结合图7、8所示,可以卷曲或折叠,形成柱状、块状等特定形状的雾化单元11,并与过滤嘴12等组装成柱状、块状的气溶胶形成单元10插入到加热器20内。
雾化单元11的电极113外露,可以在气溶胶形成单元10插入到加热器20内后,电极113与加热器20内的触点接触导通,为雾化单元11供电加热进行雾化。当然,可以理解地,雾化组件11a也可弯折形成雾化单元11,或者同时结合卷绕和弯折,形成雾化单元11。
加热体112包括在固体气溶胶形成基质111上缝制的柔性第一线材1121,第一线材1121为导电材质,缝制后固定在片状的固体气溶胶形成基质111上。电极113包括两个与第一线材1121分别电性连接的导电电极1131,导电电极1131可以与加热器20上的触点接触导通,让加热器20为加热体112供电后,加热固体气溶胶形成基质111形成气溶胶。
结合图5、6所示,在一些实施例中,第一线材1121包括由第一侧A向与第一侧A相背的第二侧B穿插后返回至第一侧A的缝接部1122,缝接部1122可以让第一线材1121缝合到固体气溶胶形成基质111上,使第一线材1121与固体气溶胶形成基质111更好地贴合,结合稳定,不易松脱。根据第一线材1121的缝合长度,可以沿缝合的走线方向设置一个或其他数量的缝接部1122,将第一线材1121缝合到固体气溶胶形成基质111。
可以理解地,在一些实施例中,缝接部1122可包括依次连接的第一段1122a、第二段1122b,第一段1122a、第二段1122b位于同一缝制孔,即缝接部1122在从第一侧A向第二侧B穿设固体气溶胶形成基质111后,再从原缝制孔返回到第一侧A,让缝接部1122埋设在固体气溶胶形成基质111内,可以加热固体气溶胶形成基质111。
通常,第一线材1121按一定的路径缝制形成加热体112,会有若干缝接部1122,以保证与固体气溶胶形成基质111的连接稳定,也保证了足够的发热范围。进一步地,第一线材1121还包括位于第一侧A,且连接在两相邻缝接部1122之间的连接段1123,可以让加热体112沿第一侧A分布的长度更长,增加加热范围。当然,也可只设置一个缝接部1122,加热体112的两端通过电极113固定到固体气溶胶形成基质111上。
采用线材缝合的方式形成加热体112,利于采用更加细的发热丝,由于截面积可以做的更小,因此热启动速度快,散热也快,可以采用更低的功率去驱动固体气溶胶形成基质111,利于节能,采用线材缝合的方式形成加热体112还利于大批量大规模的生产;丝状线材的生产工艺一般采用模孔拉丝成型,尺寸控制精准,可以使得加热体112电阻更稳定。
线材的线径通常较细,一般截面积在φ0.2mm圆形丝,将线材缝制到固体气溶胶形成基质111后形成的加热体112和固体气溶胶形成基质111制成一个整体结构,将加热体112固定在固体气溶胶形成基质111上,这样固体气溶胶形成基质111可以作为加热体112的载体,可以起到防止线材形成的加热体112变形的作用,同时可以很好的保证了加热体112和固体气溶胶形成基质111的贴合问题,而且可以还方便大批量自动化生产。
第一线材1121的可以选的材料包括:镍基合金、不锈钢系列合金,含铬合金、含钛合金、含钨合金、含钼合金、含铁合金、含锡合金、等金属材料,或者包括碳纤维丝、石墨纤维丝等非金属导电材料,还可以是极细的导电金属丝、导电非金属丝中的一种或两种加捻扭合在一起的丝状,导电金属丝、导电非金属丝较细,可以是直径为几微米至几十微米直径的细丝,具体不做限定。
进一步地,如图9所示,在其他实施例中,缝接部1122包括依次连接的第一段1122a、第三段1122c、以及第二段1122b,第三段1122c位于第二侧B,第一段1122a、第二段1122b分别穿设固体气溶胶形成基质111。在缝制时,先从第一侧A穿过固体气溶胶形成基质111到第二侧B,第一线材1121沿第二侧B引出一段后再穿过固体气溶胶形成基质111到第一侧A,如此循环,将第一线材1121缝合到固体气溶胶形成基质111上,可以让固体气溶胶形成基质111的两侧均能被加热,在加热体112发热后对固体气溶胶形成基质111加热雾化。当然,也可将第三段1122c的长度做的较短,而且也可不在第二侧B走线,稍微露出第二侧B,并沿第一段1122a所在的缝制孔返回到第一侧A。
可以理解地,如图10所示,第一线材1121可以弯折设置,弯折的方式可以采用来回弯折的方式,也可采用波形图样式的弯折方式,另外,线材也可弯曲设置,弯曲的方式可以不做限定。
进一步地,如图11所示,为了让发热辐射的区域更大,加热体112包括位于固体气溶胶形成基质111同一侧的若干根第一线材1121,优选地,第一线材1121可以为两根或两根以上的数量,各第一线材1121可以交织设置,形成网状结构,或者,各第一线材1121也可并排设置,也可交织和并排的方式组合。
优选地,在一些实施例中,加热体112还包括在固体气溶胶形成基质111上缝制的柔性第二线材1124,第一线材1121、第二线材1124分别位于固体气溶胶形成基质111的两相对侧,第一线材1121、第二线材1124相互交织,让加热体112与固体气溶胶形成基质111的结合更稳定。通常,第二线材1124可以为绝缘材质,让加热体112的第一线材1121所在侧发热,减缓加热升温速度,受热均匀,避免了气溶胶形成单元10内局部的高温而产生有害物质。当然,第二线材1124也可为导电材质,可以选择电阻较小的第一线材1121、第二线材1124,避免升温过快和温度过高。
片状的固体气溶胶形成基质111是采用草本植物通过萃取风味植物纤维,通过造纸法等方法制成的如布或者类似纸的物质,其具有一定的吸湿性,其本身被加热会产生类似草本味道的气溶胶,还可以通过将一些具有产生烟雾的容易如丙二醇、丙三醇以及食用香精充分混合成可以被雾化的溶剂,溶剂等物质被吸附到其草本植物纤维内,当加热体112产生热量是达到溶剂雾化所需的温度时,产生气溶胶。
由于第一线材1121较为柔软,片状的固体气溶胶形成基质111相当于为线材提供了支撑强度,加热体112和气溶胶形成单元10为一体结构,加热体112的热利用率比较高,可以使得被加热的固体气溶胶形成基质111很好的被利用,被更加充分地加热;另外,气溶胶形成单元10用完丢弃,相比于刺穿式加热方式,避免清洁以及损坏供电的电源设备;同时,缝制的位置和深度更均匀让产生的热量更加均匀,被加热的气溶胶形成单元10受热均匀,避免了气溶胶形成单元10内局部的高温而产生有害物质。
优选地,如图13所示,第一线材1121的两端分别电性连接有导电电极1131,为了让加热体112分段导电发热,进一步地,如图14所示,电极113还可包括与第一线材1121的两端之间连接的一个或多个导电电极1131,连接不同位置的导电电极1131,可以让加热体112的不同段参与发热,比如可以将加热体112分为上段加热部分和下端加热部分,使用时控制电路实现逐段加热。
进一步地,如图15所示,导电电极1131还包括延伸出固体气溶胶形成基质111的延伸部1132,延伸部1132为片状导体,可以贴合在导电电极1131上向外延伸出,也可在缝制导电电极1131时将延伸部1132缝制固定。在固体气溶胶形成基质111卷曲、折叠成型后,延伸部1132可以绕设或弯折到雾化组件11a的外壁面上,便于与加热器20的触点导通。当然,也可将延伸部1132取消,在固体气溶胶形成基质111卷曲、折叠成型时,可以将导电电极1131所在的区域设置在外侧。
结合图3、16所示,当导电电极1131延伸出固体气溶胶形成基质111时,导电电极1131由气溶胶形成单元10侧壁面引出后沿气溶胶形成单元10的周向设置,可以在气溶胶形成单元10插入或放置到加热器20上时,任何转向都能与加热器20上的接触触点211接触。
当然,如图17、18所示,在其他实施例中,导电电极1131也可由气溶胶形成单元10的端部引出后设置在气溶胶形成单元10的端部,也可由端部引出后弯折到气溶胶形成单元10的侧壁面,与加热器20上对应位置的接触触点211接触导通。
优选地,再结合图13、14所示,在本实施例中,固体气溶胶形成基质111包括发热段1111、以及包覆段1112,加热体112设置在发热段1111,电极113位于包覆段1112,可以在卷绕或折叠时,包覆段1112位于最外层,包覆内部卷绕或折叠的发热段1111,内部发热段1111的热量可以传递到外面的包覆段1112,加热雾化包覆段1112,而不用加热体112直接加热包覆段1112,避免外侧温度过高。当然,在其他实施例中,也可不区分发热段1111、包覆段1112,加热体112在固体气溶胶形成基质111上各区域分布。
在一些实施例中,导电电极1131可以由第一线材1121缝制到固体气溶胶形成基质111上形成,利于雾化组件11a的批量化、自动化生产。可以理解地,也可为部分导电电极1131采用另外的导电线编织到固体气溶胶形成基质111上。
进一步地,两个导电电极1131位于固体气溶胶形成基质111的同一侧,优选地,导电电极1131与第一线材1121为同一条导电线,导电电极1131、加热体112可以由一根导电线一次缝制完成,提升了生产效率。
当然,在其他实施例中,也可为其中一个导电电极1131位于第一侧A,另一个导电电极1131位于第二侧B,位于第一侧A的导电电极1131可以与第一线材1121为同一条导电线,位于第二侧B的导电电极1131则单独缝制,与加热体112位于第二侧B的线材接触导通。
进一步地,缝制形成的导电电极1131上可以设有导电层,可以使电阻稳定,方便外接引线或触头。在一些实施例中,导电层由导电浆或导电胶形成,导电胶、导电浆可以涂覆或印刷上去。
可以理解地,在其他实施例中,导电层也可为金属片,贴合到导电电极1131上。金属片的材质可以是镍、不锈钢、铜、铝箔等,再通过缝纫方式穿刺金属片缝制到固体气溶胶形成基质111,使其固定复合在一起,这样做的好处是使导电电极1131会有一定的硬度支撑,可以更加方便地和加热器20内的触点连接。
结合图19、20所示,在一些实施例中,雾化组件11a还包括在固体气溶胶形成基质111的至少一侧设置、用于导热的导热层114,导热层114为绝缘材质。通过加热体112将导热层114与固体气溶胶形成基质111固定为一个整体,这样加热体112产生的热量可以通过导热层114均匀散开,而不是集中在靠近加热体112的部分,可以使得固体气溶胶形成基质111各部分受热均匀,避免局部被加热碳化,而另外部分未被加热被浪费的情况。
结合图5、6所示,本申请另一实施例中还公开了一种雾化组件11a的制作工艺,包括以下步骤:
S11、提供柔性的固体气溶胶形成基质111、以及柔性的第一线材1121,第一线材1121为导电材质;
S12、将第一线材1121缝制在固体气溶胶形成基质111上,第一线材1121缝合到固体气溶胶形成基质111,形成加热体112;
S13、在固体气溶胶形成基质111上设置与加热体112电性连接的导电电极1131。
在步骤S12中,缝制第一线材1121时,将第一线材1121由第一侧A穿至第二侧B后由同一缝制孔返回至第一侧A,让第一线材1121形成嵌设在固体气溶胶形成基质111内的缝制部。
缝制第一线材1121时形成至少一个由第一侧A向与第一侧A相背的第二侧B穿插后返回至第一侧A的缝接部1122。
当然,结合图9所示,缝制第一线材1121时,第一线材1121也可由第一侧A穿至第二侧B后沿第二侧B走线后再穿至第一侧A。第一线材1121在固体气溶胶形成基质111上的缝制方式不做限定,能让第一线材1121与固体气溶胶形成基质111结合固定即可。
进一步地,结合图12所示,在一些实施例中,步骤S12还包括:提供柔性的第二线材1124,将第一线材1121、第二线材1124分别从固体气溶胶形成基质111的两侧缝制,让第一线材1121、第二线材1124交织到固体气溶胶形成基质111,形成加热体112,第一线材1121、第二线材1124交织后的加热体112与固体气溶胶形成基质111结合更稳定。
在一些实施例中,步骤S13中,可以将一个导电电极1131缝制形成,也可将两个导电电极1131都缝制形成。另外,并在缝制形成的导电电极1131上设置导电层。
进一步地,结合图13、14所示,固体气溶胶形成基质111包括发热段1111、以及包覆段1112,在步骤S12中,在发热段1111设置加热体112,在步骤S13中,在包覆段1112设置电极113。
优选地,固体气溶胶形成基质111由导液原材分切形成,为了提升生产效率,可以先在导液原材上按固体气溶胶形成基质111的排布方式缝制形成加热体112、以及设置导电电极1131后,再分切形成雾化组件11a。多个雾化组件11a的加热体112、电极113可以一次制作完成,适合大批量生产,效率高。
结合图7、8所示,本申请另一实施例中还公开了一种上述气溶胶形成单元10的制作工艺,包括以下步骤:
将上述制作的雾化组件11a采用卷绕、弯折,或者卷绕、弯折结合的方式形成雾化单元11,且导电电极1131外露。
进一步地,结合图1至3所示,还包括步骤:在雾化单元11一端设置的过滤嘴12。
进一步地,电极113位于包覆段1112,让包覆段1112包覆在雾化单元11外周。
当部分或全部导电电极1131包括延伸出固体气溶胶形成基质111的延伸部1132时,制作工艺还包括以下步骤:
结合图16至18所示,让延伸部1132沿气溶胶形成单元10的周向绕设,或由加热体112的端部引出后设置在加热体112的端部或侧壁面,让延伸部1132位于气溶胶形成单元10的外侧,利用与加热器20的触点导通。
如图4所示,本申请另一实施例中还公开了一种加热器20,包括供气溶胶形成单元10放置的工作位21,工作位21设有与导电电极1131位置对应的接触触点211,以向加热体112通电后让加热体112发热。
加热器20的工作位21为插孔,供气溶胶形成单元10插接,在其他实施例中,工作位21也可为卡口,供气溶胶形成单元10卡合后固定。
加热器20内可以设置电池22,也可设置给电池22充电的充电板23,同时,控制板24可以控制电池22向接触触点211的供电,以控制加热气溶胶形成单元10。
可以理解地,上述各技术特征可以任意组合使用而不受限制。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
