Description

一种雾化器及电子烟 技术领域
本发明特别涉及一种雾化器及电子烟。
背景技术
现有的一种雾化器包括外壳和雾化芯，外壳内设有油仓和容纳腔，外壳上还开设可向油仓内注油的注油孔，外壳端部与可打开或关闭该注油孔的上盖相连；雾化芯设于所述容纳腔内，且雾化芯包括进油孔、导油机构及雾化件；外壳内还设有雾化套，雾化芯伸入该雾化套内，雾化套侧壁开设过油孔；油仓依次通过过油孔、进油孔、导油机构与雾化件相连通。
当通过上盖打开注油孔时，即可向油仓内注油。在向油仓注油的过程中，若油仓与雾化芯之间的油路始终导通，则由于注油时油仓内压强增大，油仓内的烟油容易通过过油孔及雾化芯漏出。
为避免在注油时出现漏油现象，现有的做法是将雾化套与上盖设计为联动旋转结构，即在旋转上盖打开注油孔的同时，雾化套也同步旋转并使得过油孔与进油孔错位，从而油路截断，在注油时可以防止烟油从雾化芯漏出。当注油完毕，旋转上盖关闭注油孔，雾化套也同步旋转直至过油孔与进油孔对位，油路导通，可正常使用雾化器。
上述这种旋转隔油结构所使用的零部件多，组装复杂。同时，由于雾化套多次转动后容易出现磨损，而更换雾化套非常不方便，带来的后果是用户将雾化套连同外壳等部件整体丢弃，导致使用成本增加，用户体验差。
此外，传统的雾化器中没有设置防止吸食到烟油珠的相应结构，因而雾化件雾化产生烟雾中的大颗粒烟油珠容易进入用户口腔，从而影响烟雾口感并易烫伤用户口腔，用户体验差。
为解决上述问题，出现了在靠近雾化件处设置防止吸食到烟油珠结构的雾化器。虽然可以阻挡雾化产生的烟雾中的大颗粒烟油珠，但由于在出气道中还是存在冷凝的烟雾，因而用户在使用雾化器时还是会有吸食到烟油珠的感觉，烟雾口感差，用户体验差。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种改进了的雾化器及电子烟。
现有技术中设计依靠上盖带动雾化套旋转的旋转隔油结构，结构复杂、成本高，为解决该技术问题，本发明所采用的技术方案是：
一种雾化器，包括外壳和雾化芯，外壳内设有油仓和容纳腔，外壳上还开设可向油仓内注油的注油孔，外壳端部与可绕外壳轴线转动并打开或关闭该注油孔的上盖相连；雾化芯可拆卸式设于所述容纳腔内，且雾化芯包括进油孔、导油机构及雾化件；外壳内还设有雾化套，雾化芯伸入该雾化套内，雾化套侧壁开设过油孔；油仓依次通过过油孔、进油孔、导油机构与雾化件相连通；其结构特点是所述上盖与所述雾化芯可拆卸相连，且上盖可带动雾化芯同步旋转。
借由上述结构，在注油孔关闭状态下，油仓的过油孔为打开状态，油仓与雾化芯的导油机构导通，此时雾化器通电后雾化件即可雾化烟油产生烟雾，满足用户吸烟的需求。当需要往油仓内注油时，旋转上盖至打开注油孔，由于上盖与所述雾化芯可拆卸相连，且上盖可带动雾化芯同步旋转，因此，在旋转上盖打开注油孔的同时，雾化芯在雾化套内腔转动，当注油孔打开时，雾化芯转动至过油孔与进油孔错位，从而关闭过油孔，油路截断，防止注油时因油仓压强变化而引起烟油被挤压到雾化芯上，在注油时可以防止烟油从雾化芯漏出。当注油完毕，旋转上盖至关闭注油孔，此时雾化芯同步旋转至过油孔与进油孔对位，油路导通，从而可以正常雾化产烟。
可见，本发明中，在旋转上盖打开注油孔的同时通过转动雾化芯截断油仓与雾化芯之间的油路，由于雾化芯拆卸方便(现有技术中已有多种成熟的雾化芯的可拆卸安装结构)，因而操作简单，更换方便，降低了使用成本。
作为一种优选方式，所述上盖具有向雾化套内腔延伸的连接环，所述连接环与雾化芯可 拆卸相连。
进一步地，所述连接环外壁具有两相对设置的第一驱动面，所述雾化芯内壁具有与所述第一驱动面对应配合的第二驱动面。
借由上述结构，当雾化芯组装在外壳内时，连接环的第一驱动面与雾化芯的第二驱动面相互配合，使得雾化芯与上盖一起转动，从而使得注油时油仓与雾化芯之间的油路截断，防止注油时漏油。此外，在往外壳内组装雾化芯时，第一驱动面与第二驱动面相配合起到安装对位作用，保证雾化芯与外壳组装后过油孔与进油孔对位连通，防止在吸烟时过油孔与进油孔对位不精准，避免供油不足而影响雾化效果；由于连接环的第一驱动面与雾化芯的第二驱动面相互配合是通过面与面配合，所以在更换雾化芯时只要拔出雾化芯即可，不需要对外壳或上盖做任何动作，因此操作简单，方便快捷。
进一步地，所述外壳上设有限位部，所述限位部与雾化芯端面之间设置固定环，该固定环套设于连接环外并与连接环过盈配合。
借由上述结构，上盖与外壳之间的连接关系，通过固定环来固定，使得上盖只能在外壳的上端面配合下转动，避免上盖轴向拔出而影响其对注油孔的封油效果。
作为一种优选方式，所述雾化套与外壳一体成型。
借由上述结构，外壳与雾化套一体成型，减少了物料成本及制造成本，同时雾化套的密封效果更好。
进一步地，外壳上设有用于引导上盖绕外壳轴线旋转的导槽，上盖上具有与该导槽相配合的导向部。
设置相互配合的导槽与导向部，从而使得上盖旋转更加平稳顺畅。
进一步地，所述外壳内设有第一密封垫，第一密封垫中心位置开设第一通孔，雾化芯上部穿过该第一通孔，雾化芯中段固设于该第一通孔内。
进一步地，所述第一通孔侧壁周向设有与雾化芯抵接的凸圈。
借由上述结构，在雾化芯通过第一通孔插入雾化套内时，凸圈可夹紧雾化芯外侧壁并起到密封作用；同时，凸圈还可以起到减小雾化芯在转动时受到的摩擦力的作用，使得上盖可带动雾化芯顺畅转动。
进一步地，所述外壳底部设有底盖，所述底盖中心位置开设第二通孔，雾化芯上部依次穿过第二通孔、第一通孔并伸入雾化套内腔中，雾化芯底部固设于所述第二通孔内；底盖上设有用于将雾化芯从容纳腔取出的扣手部。
设置拔出雾化芯的扣手部，方便更换雾化芯。
进一步地，所述雾化芯包括外套管和导电片，所述雾化件为超声波雾化片，雾化件与导电片均通过雾化座固设于外套管内，且雾化件的一电极层与导电片一侧面相抵接。
借由上述结构，超声波雾化片与导电片接触导电，超声波雾化片上不需要焊接电子线，使得超声波雾化片导电更加良好，同时可以避免高温焊接造成超声波雾化片性能减弱或破坏，还可以降低超声波雾化片的安装成本。
进一步地，还包括吸嘴盖，所述上盖与所述吸嘴盖固连，且吸嘴盖可带动上盖同步旋转。
通过吸嘴盖受力，带动上盖及雾化芯旋转，方便着力，操作方便省力。
现有技术在靠近雾化件处设置防止吸食到烟油珠结构，在出气道中还是存在冷凝的烟雾，用户在使用雾化器时还是会有吸食到烟油珠的感觉，烟雾口感差，为解决该技术问题，本发明所采用的技术方案是：
进一步地，所述外壳内设有出气道，外壳一端设有吸嘴盖，吸嘴盖上开设出气孔，进气孔、雾化件、出气道、出气孔依次相通；还包括设于出气孔处的阻油件，所述吸嘴盖上开设阻油腔，所述阻油件上开设连通所述阻油腔出气端与所述出气孔的第一过气孔，第一过气孔的孔径小于小于阻油腔的孔径。
借由上述结构，阻油腔主要用于收集出气道冷凝的烟油珠。由于阻油件与阻油腔之间形成台阶部，当倾斜电子烟吸烟时，出气道内冷凝烟雾形成的烟油珠受到台阶部的阻挡，因而 不易进入用户口腔、被用户吸食，烟雾口感好，用户体验好。
进一步地，所述第一过气孔的侧壁具有向阻油腔内延伸的第一延伸段，第一延伸段的外径小于阻油腔的内径，第一延伸段的长度小于阻油腔的长度。
借由上述结构，可进一步降低用户吸食到冷凝烟雾形成的烟油珠的概率。
进一步地，上盖与吸嘴盖相连，所述上盖上具有安装部，安装部固设于吸嘴盖上的安装槽内，所述安装部上开设连通阻油腔与出气道的第二过气孔，第二过气孔的孔径小于小于阻油腔的孔径。
进一步地，所述第二过气孔的侧壁具有向阻油腔内延伸的第二延伸段，第二延伸段的外径小于阻油腔的内径，第一延伸段与第二延伸段的长度之和小于阻油腔的长度。
借由上述结构，上盖的第二延伸段伸入阻油腔内，且第二延伸段的外径小于阻油腔的内径，从而避免阻油腔内的烟油珠掉落到出气道内而影响再次吸烟时的烟雾口感。
优选地，所述阻油件与吸嘴盖一体成型；或者，所述阻油件与吸嘴盖可拆卸相连。
阻油件与吸嘴盖一体成型时，减少了物料成本及制造成本。
阻油件与吸嘴盖可拆卸相连时，当吸烟时间比较久时，可以将阻油件从吸嘴盖上取下，然后将阻油腔内的烟油珠清理掉，进一步防止吸食到烟油珠。
基于同一个发明构思，本发明还提供了一种电子烟，其结构特点是包括所述的雾化器。
与现有技术相比，本发明具有以下有益效果：
第一，在旋转上盖打开注油孔的同时转动雾化芯，使得油仓的过油孔关闭，油路截断，防止注油时因油仓内压强增大而漏油；由于雾化芯可拆卸更换，因而操作简单，更换方便，降低了使用成本。
第二，在吸嘴盖上设置阻油珠结构，由于阻油珠结构靠近用户口腔，因而极大地减少用户吸食到冷凝烟雾形成的烟油珠的概率，烟雾口感好，用户体验好。

具体实施方式
实施例一
如图1至图7所示，本发明电子烟中的雾化器实施例一包括外壳1和雾化芯6，外壳1内设有油仓2和容纳腔106，外壳1上还开设可向油仓2内注油的注油孔101，外壳1端部与可绕外壳1轴线转动并打开或关闭该注油孔101的上盖3相连；雾化芯6可拆卸式设于所述容纳腔106内，且雾化芯6包括进油孔6011、导油机构602及雾化件612；外壳1内还设有雾化套7，雾化芯6伸入该雾化套7内，雾化套7侧壁开设过油孔701；油仓依次通过过油孔701、进油孔6011、导油机构602与雾化件612相连通；所述上盖3与所述雾化芯6可拆卸相连，且上盖3可带动雾化芯6同步旋转。
在注油孔101关闭状态下，油仓2的过油孔为打开状态，油仓2与雾化芯6的导油机构602导通，此时雾化器通电后雾化件612即可雾化烟油产生烟雾，满足用户吸烟的需求。如图1中箭头所示，在雾化器工作时，油仓2内的烟油依次通过过油孔701、进油孔6011达到导油机构602，再由导油机构602导致雾化件612上雾化产烟，供用户吸食。
当需要往油仓2内注油时，旋转上盖3至打开注油孔101，由于上盖3与所述雾化芯6可拆卸相连，且上盖3可带动雾化芯6同步旋转，因此，在旋转上盖3打开注油孔101的同时，雾化芯6在雾化套7内腔转动，当注油孔101打开时，雾化芯6转动至过油孔701与进油孔6011错位，从而关闭过油孔701，油路截断，防止注油时因油仓2压强变化而引起烟油被挤压到雾化芯6上，在注油时可以防止烟油从雾化芯6漏出。当注油完毕，旋转上盖3至关闭注油孔101，此时雾化芯6同步旋转至过油孔701与进油孔6011对位，油路导通，从而可以正常雾化产烟。
可见，本发明中，在旋转上盖3打开注油孔的同时通过转动雾化芯6截断油仓2与雾化芯6之间的油路，由于雾化芯6拆卸方便(现有技术中已有多种成熟的雾化芯6的可拆卸安装结构)，因而操作简单，更换方便，降低了使用成本。
所述上盖3具有向雾化套7内腔延伸的连接环304，所述连接环304与雾化芯6可拆卸相连。所述连接环304外壁具有两相对设置的第一驱动面3041，所述雾化芯6内壁具有与所述第一驱动面3041对应配合的第二驱动面6091。当雾化芯6组装在外壳1内时，连接环304的第一驱动面3041与雾化芯6的第二驱动面6091相互配合，使得雾化芯6与上盖3一起转动，从而使得注油时油仓2与雾化芯6之间的油路截断，防止注油时漏油。此外，在往外壳1内组装雾化芯6时，第一驱动面3041与第二驱动面6091相配合起到安装对位作用，保证雾化芯6与外壳1组装后过油孔701与进油孔6011对位连通，防止在吸烟时过油孔701与进油孔6011对位不精准，避免供油不足而影响雾化效果。
所述外壳1上设有限位部108，所述限位部108与雾化芯6端面之间设置固定环17，该固定环17套设于连接环304外并与连接环304过盈配合。上盖3与外壳1之间的连接关系，通过固定环17来固定，使得上盖3只能在外壳1的上端面配合下转动，避免上盖3轴向拔出而影响其对注油孔101的封油效果。
所述雾化套7与外壳1一体成型，减少了物料成本及制造成本，同时雾化套7的密封效果更好。
外壳1上设有用于引导上盖3绕外壳1轴线旋转的导槽107，上盖3上具有与该导槽107相配合的导向部303，从而使得上盖3旋转更加平稳顺畅。

所述第一通孔901侧壁周向设有与雾化芯6抵接的凸圈9011。在雾化芯6通过第一通孔901插入雾化套7内时，凸圈9011可夹紧雾化芯6外侧壁并起到密封作用；同时，凸圈9011还可以起到减小雾化芯6在转动时受到的摩擦力的作用，使得上盖3可带动雾化芯6顺畅转动。
所述外壳1底部设有底盖10，所述底盖10中心位置开设第二通孔1001，雾化芯6上 部依次穿过第二通孔1001、第一通孔901并伸入雾化套7内腔中，雾化芯6底部固设于所述第二通孔1001内；底盖10上设有用于将雾化芯6从容纳腔106取出的扣手部1002。设置拔出雾化芯6的扣手部1002，方便更换雾化芯6。
雾化芯6顶部与雾化套7内壁之间设有第一密封圈11，连接环304与外壳1之间设有第二密封圈12。
所述雾化芯6包括外套管601和导电片610，所述雾化件612为超声波雾化片，雾化件612与导电片610均通过雾化座605(由硅胶制成)固设于外套管601内，且雾化件612的一电极层与导电片610一侧面相抵接。超声波雾化片与导电片610接触导电，超声波雾化片上不需要焊接电子线，使得超声波雾化片导电更加良好，同时可以避免高温焊接造成超声波雾化片性能减弱或破坏，还可以降低超声波雾化片的安装成本。
雾化器还包括吸嘴盖4，所述上盖3与所述吸嘴盖4固连，且吸嘴盖4可带动上盖3同步旋转。通过吸嘴盖4受力，带动上盖3及雾化芯6旋转，方便着力，操作方便省力。
所述雾化芯6还包括密封套603(由硅胶制成)、压棉弹簧604、PCB板606、底环607、绝缘环608、内套管609、弹性电极611，导油机构602包括杯状导油棉；其中，内套管609与外套管601内外套接，杯状导油棉侧壁夹设于内套管609与外套管601之间，杯状导油棉外底面与超声雾化片的雾化面相接触。密封套603套设于外套管601外。所述进油孔6011开设于外套管601侧壁，密封套603上具有与所述进油孔6011相对的过油槽6031。压棉弹簧604一端与内套管609底部相抵接，压棉弹簧604另一端与杯状导油棉内底面相抵接。
所述第二驱动面6091设于所述内套管609内侧壁顶部。

雾化器还包括磁吸件13，磁吸件13固设于底盖10上，在雾化器与电子烟的供电组件相连时提供磁吸力。

吸嘴盖4上开设进气孔401和出气孔402，通气管15与内套管609之间形成出气道16，进气孔401、雾化件612、出气道16、出气孔402依次相通。气体从进气孔401进入，经过通气管15后到达杯状导油棉底面，将超声波雾化片雾化产生的烟雾依次经由出气道16、出气孔402带出，供用户吸食。
雾化器还包括设于出气孔402处的阻油件18，所述吸嘴盖4上开设阻油腔403，所述阻油件18上开设连通所述阻油腔403出气端与所述出气孔402的第一过气孔1801，第一过气孔1801的孔径小于小于阻油腔403的孔径。阻油腔403主要用于收集出气道16冷凝的烟油珠。由于阻油件18与阻油腔403之间形成台阶部，当倾斜电子烟吸烟时，出气道16内冷凝烟雾形成的烟油珠受到台阶部的阻挡，因而不易进入用户口腔、被用户吸食，烟雾口感好，用户体验好。
所述第一过气孔1801的侧壁具有向阻油腔403内延伸的第一延伸段18011，第一延伸段18011的外径小于阻油腔403的内径，第一延伸段18011的长度小于阻油腔403的长度，从而进一步降低用户吸食到冷凝烟雾形成的烟油珠的概率。

实施例二
如图8至图10所示，本发明电子烟中的雾化器实施例二包括包括外壳1，外壳1内设有雾化件612和出气道16，外壳1一端设有吸嘴盖4，吸嘴盖4上开设出气孔402，进气孔401、雾化件612、出气道16、出气孔402依次相通，还包括设于出气孔402处的阻油件18，所述吸嘴盖4上开设阻油腔403，所述阻油件18上开设连通所述阻油腔403出气端与所述出气孔401的第一过气孔1801，第一过气孔1801的孔径小于小于阻油腔403的孔径。
阻油腔403主要用于收集出气道16冷凝的烟油珠。由于阻油件18与阻油腔403之间形成台阶部，当倾斜电子烟吸烟时，出气道16内冷凝烟雾形成的烟油珠受到台阶部的阻挡，因而不易进入用户口腔、被用户吸食，烟雾口感好，用户体验好。
所述第一过气孔1801的侧壁具有向阻油腔403内延伸的第一延伸段18011，第一延伸段18011的外径小于阻油腔403的内径，第一延伸段18011的长度小于阻油腔403的长度，从而进一步降低用户吸食到冷凝烟雾形成的烟油珠的概率。
所述外壳1端部设有上盖3，该上盖3与吸嘴盖4相连，所述上盖3上具有安装部305，安装部305固设于吸嘴盖4上的安装槽内，所述安装部305上开设连通阻油腔403与出气道16的第二过气孔3051，第二过气孔3051的孔径小于小于阻油腔403的孔径。
所述第二过气孔3051的侧壁具有向阻油腔403内延伸的第二延伸段30511，第二延伸段30511的外径小于阻油腔403的内径，第一延伸段18011与第二延伸段30511的长度之和小于阻油腔403的长度。上盖3的第二延伸段30511伸入阻油腔403内，且第二延伸段30511的外径小于阻油腔403的内径，从而避免阻油腔403内的烟油珠掉落到出气道16内而影响再次吸烟时的烟雾口感。
所述阻油件18与吸嘴盖4一体成型，减少了物料成本及制造成本。
外壳1内设有雾化芯6、油仓2和容纳腔106，外壳1上还开设可向油仓2内注油的注油孔101，上盖3可绕外壳1轴线转动并打开或关闭该注油孔101，雾化芯6可拆卸式设于所述容纳腔106内，且雾化芯6包括进油孔6011、导油机构602，外壳1内还设有雾化套7，雾化芯6伸入该雾化套7内，雾化套7侧壁开设过油孔701；油仓依次通过过油孔701、进油孔6011、导油机构602与雾化件612相连通；所述上盖3与所述雾化芯6可拆卸相连，且上盖3可带动雾化芯6同步旋转。
所述上盖3与所述吸嘴盖4固连，且吸嘴盖4可带动上盖3同步旋转。通过吸嘴盖4受力，带动上盖3及雾化芯6旋转，方便着力，操作方便省力。
在注油孔101关闭状态下，油仓2的过油孔为打开状态，油仓2与雾化芯6的导油机构602导通，此时雾化器通电后雾化件612即可雾化烟油产生烟雾，满足用户吸烟的需求。
当需要往油仓2内注油时，通过吸嘴盖4旋转上盖3至打开注油孔101，由于上盖3与所述雾化芯6可拆卸相连，且上盖3可带动雾化芯6同步旋转，因此，在旋转上盖3打开注油孔101的同时，雾化芯6在雾化套7内腔转动，当注油孔101打开时，雾化芯6转动至过油孔701与进油孔6011错位，从而关闭过油孔701，油路截断，防止注油时因油仓2压强变化而引起烟油被挤压到雾化芯6上，在注油时可以防止烟油从雾化芯6漏出。
当注油完毕，旋转上盖3至关闭注油孔101，此时雾化芯6同步旋转至过油孔701与进油孔6011对位，油路导通，从而可以正常雾化产烟。
可见，本发明中，在旋转上盖3打开注油孔的同时通过转动雾化芯6截断油仓2与雾化芯6之间的油路，由于雾化芯6拆卸方便(现有技术中已有多种成熟的雾化芯6的可拆卸安装结构)，因而操作简单，更换方便，降低了使用成本。
所述上盖3具有向雾化套7内腔延伸的连接环304，所述连接环304与雾化芯6可拆卸相连。所述连接环304外壁具有两相对设置的第一驱动面3041，所述雾化芯6内壁具有与所述第一驱动面3041对应配合的第二驱动面6091。当雾化芯6组装在外壳1内时，连接环304的第一驱动面3041与雾化芯6的第二驱动面6091相互配合，使得雾化芯6与上盖3一起转动，从而使得注油时油仓2与雾化芯6之间的油路截断，防止注油时漏油。此外，在 往外壳1内组装雾化芯6时，第一驱动面3041与第二驱动面6091相配合起到安装对位作用，保证雾化芯6与外壳1组装后过油孔701与进油孔6011对位连通，防止在吸烟时过油孔701与进油孔6011对位不精准，避免供油不足而影响雾化效果。
所述外壳1上设有用于防止雾化芯6从外壳1顶部拔出的限位部108。
外壳1上设有用于引导上盖3绕外壳1轴线旋转的导槽107，上盖3上具有与该导槽107相配合的导向部303，从而使得上盖3旋转更加平稳顺畅。

所述第一通孔侧壁周向设有与雾化芯6抵接的凸圈。在雾化芯6通过第一通孔插入雾化套7内时，凸圈可夹紧雾化芯6外侧壁并起到密封作用；同时，凸圈还可以起到减小雾化芯6在转动时受到的摩擦力的作用，使得上盖3可带动雾化芯6顺畅转动。
所述外壳1底部设有底盖10，所述底盖10中心位置开设第二通孔，雾化芯6上部依次穿过第二通孔、第一通孔并伸入雾化套7内腔中，雾化芯6底部固设于所述第二通孔内；底盖10上设有用于将雾化芯6从容纳腔106取出的扣手部1002。设置拔出雾化芯6的扣手部1002，方便更换雾化芯6。

所述雾化芯6还包括密封套603(由硅胶制成)、压棉弹簧604、PCB板606、底环607、绝缘环608、内套管609、弹性电极611，导油机构602包括杯状导油棉；其中，内套管609与外套管601内外套接，杯状导油棉侧壁夹设于内套管609与外套管601之间，杯状导油棉外底面与超声雾化片的雾化面相接触。密封套603套设于外套管601外。所述进油孔6011开设于外套管601侧壁，密封套603上具有与所述进油孔6011相对的过油槽6031。压棉弹簧604一端与内套管609底部相抵接，压棉弹簧604另一端与杯状导油棉内底面相抵接。
