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
现有的雾化器包括外壳，外壳顶部设有吸嘴座，吸嘴座上连有吸嘴，吸嘴座上开设进气孔，外壳内设有进气通道、出气通道、产烟单元、用于雾化产烟单元以获得烟雾的雾化单元，进气孔、进气通道、产烟单元、出气通道、吸嘴依次相通。雾化器工作时，气流从进气孔进入，通过进气通道后带走产烟单元产生的烟雾，依次通过出气通道和吸嘴进入用户口腔。
为满足不同肺活量用户的需求，需要调节气流通道的气流量。通常的解决方案是在吸嘴座上与进气孔对应的位置套设一个调气环，调气环上开设调气孔，转动调气环，可以调节调节孔与进气孔之间的对位面积，从而实现对气流通道气流量的调节。
现有的这种结构的雾化器具有以下缺点：
第一，调气环的手持部面积较小，在旋转调气过程中，由于不好着力，因而不好把控调节力度，很难调节到合适的进气量，操作不方便，用户体验差。
第二，若吸嘴座兼用作注油盖，则调气过程容易误开注油盖，导致烟油漏出，同时由于油仓失去负压，导油棉导油速度过快，容易吸到烟油。
第三，进气通道和出气通道没有完全隔离，导致烟雾口感不够饱满细腻。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种雾化器及电子烟，旋转吸嘴即可调节进气量，操作简单方便，调节力度容易把控，用户体验好。
为解决上述技术问题，本发明所采用的技术方案是：
一种雾化器，包括外壳，外壳顶部设有吸嘴座，吸嘴座上连有吸嘴，吸嘴座上开设进气孔，外壳内设有气管，气管内设有进气通道，气管侧壁上开设用于连通进气孔与进气通道的第一过气孔，其结构特点是所述吸嘴顶端具有向吸嘴内腔延伸的延伸段，该延伸段底端面周向设有若干个高低不等的台阶部，所述气管顶端具有与任一台阶部相抵接的支撑部，吸嘴与吸嘴座间隙配合并可周向转动，雾化器还包括在吸嘴周向转动时引导气管轴向移动并限制气管周向转动的引导机构；气管轴向移动使得进气孔与第一过气孔的对位面积改变。
借由上述结构，当需要调节进气量时，旋转吸嘴，由于吸嘴延伸段底端面周向设有若干个高低不等的台阶部，所述气管顶端具有与任一台阶部相抵接的支撑部，引导机构在吸嘴周向转动时引导气管轴向移动并限制气管周向转动的，因而吸嘴旋转时，气管会轴向上下移动，从而改变进气孔与第一过气孔的对位面积，每个台阶部对应一个调节档位，从而实现进气量的多档调节。本发明中，由于调气时的着力处为吸嘴，因而操作简单方便，调节力度容易把控，用户体验好。
作为一种优选方式，所述引导机构包括套设于气管与吸嘴座之间的进气座，进气座上开设连通进气孔与第一过气孔的第二过气孔，气管外壁上设有第一限位平面，进气座内壁具有与第一限位平面相配合的第二限位平面。
通过第一限位平面与第二限位平面的配合限位作用，可以限制气管周向转动并在吸嘴转动时引导气管轴向上下移动。
进一步地，所述引导机构还包括套设于进气座与气管之间的密封座，进气座与密封座卡扣相连，密封座内壁具有与第一限位平面相配合的第三限位平面。
密封座的设置，可以保证气路的密封性，防止漏气。
进一步地，还包括转盘和压簧，转盘外壁与吸嘴内壁固连，吸嘴与吸嘴座外壁间隙配合，转盘与吸嘴座内壁间隙配合；压簧和转盘均套设于气管外，压簧底部设于转盘上的限位槽内，压簧顶部与气管底端的限位凸缘相抵接。
转盘与吸嘴固连并形成一个旋转体，吸嘴与吸嘴座外壁间隙配合，转盘与吸嘴座内壁间隙配合，从而旋转体可以绕吸嘴座轴线360°旋转。
压簧的设置，可以保证支撑部与台阶部的可靠抵接，保证调气功能能够实现。
作为一种优选方式，所述外壳内设有油仓，所述吸嘴座上开设用于向油仓内注油的注油孔。
由于吸嘴、转盘均与吸嘴座间隙配合，旋转体转动时不会带动吸嘴座转动。将吸嘴座兼用作注油盖，调气过程不会误开注油盖。
进一步地，所述气管内还设有与吸嘴连通的出气通道，气管侧壁上开设用于连通进气通道与出气通道的第三过气孔，气管内具有将出气通道与进气通道隔离的隔离层。
借由上述结构，进气管内的进气通道和出气通道完全密封隔离，使气流流经进气通道、超声雾化片和出气通道及吸嘴，既可以将超声雾化片雾化出来的烟雾带走又可以使烟雾口感饱满细腻。
进一步地，各台阶部底面两侧具有与相邻台阶部底面平滑过度相连的倒斜角。
倒斜角的设置使得支撑部在各档位调气之间滑动更加顺畅。
作为一种优选方式，密封座内壁开设至少一个卡槽，进气座上具有与卡槽相配合的卡勾。
在组装时通过密封座上的卡槽和进气座上的卡勾相互卡接使得进气孔和进气通道连通性更好，同时也使密封座和进气座密封性好且形成一体，组装方便省时。
作为一种优选方式，所述吸嘴与转盘铆接。
作为一种优选方式，所述支撑部的高度取值范围为1mm～15mm，所述延伸段底端的厚度取值范围为3mm～8mm。
借由上述结构，气管顶端与延伸段底端之间形成一个空间容量较大的直径大于延伸段内径的空腔，从而烟雾在该空腔内的流速相对缓慢，导致烟雾中的大颗粒液滴容易冷凝在该空腔内，防止用户吸食到大颗粒烟油液滴，烟雾口感好且不会烫伤嘴部。冷凝在该空腔内的烟油液滴还会顺着转盘内壁流入转盘与气管之间的腔体内，当该腔体内的烟油液滴随着使用时间的增长而积存较多时，可以通过甩动吸嘴将积存的烟油液滴甩出。
基于同一个发明构思，本发明还提供了一种电子烟，其特点是包括所述的雾化器。
与现有技术相比，本发明旋转吸嘴即可调节进气量，操作简单方便，调节力度容易把控；调气过程不会误开注油盖；进气通道和出气通道完全隔离，气道密封性能好，烟雾口感饱满细腻，用户体验好。

具体实施方式
如图1至图9所示，本发明电子烟中的雾化器包括外壳1，外壳1顶部设有吸嘴座2，吸嘴座2上连有吸嘴3，吸嘴座2上开设进气孔201，外壳1内设有气管4，气管4内设有进气通道401，气管4侧壁上开设用于连通进气孔201与进气通道401的第一过气孔402，所述吸嘴3顶端具有向吸嘴3内腔延伸的延伸段301，该延伸段301底端面周向设有若干个高低不等的台阶部3011，所述气管4顶端具有与任一台阶部3011相抵接的支撑部403，吸嘴3与吸嘴座2间隙配合并可周向转动，雾化器还包括在吸嘴3周向转动时引导气管4轴向移动并限制气管4周向转动的引导机构5；气管4轴向移动使得进气孔201与第一过气孔402的对位面积改变。
当需要调节进气量时，旋转吸嘴3，由于吸嘴3延伸段301底端面周向设有若干个高低不等的台阶部3011，所述气管4顶端具有与任一台阶部3011相抵接的支撑部403，引导机构5在吸嘴3周向转动时引导气管4轴向移动并限制气管4周向转动的，因而吸嘴3旋转时，气管4会轴向上下移动，从而改变进气孔201与第一过气孔402的对位面积，每个台阶部3011对应一个调节档位，从而实现进气量的多档调节。本发明中，由于调气时的着力处为吸嘴3，因而操作简单方便，调节力度容易把控，用户体验好。
所述引导机构5包括套设于气管4与吸嘴座2之间的进气座501，进气座501上开设连通进气孔201与第一过气孔402的第二过气孔5011，气管4外壁上设有第一限位平面404，进气座501内壁具有与第一限位平面404相配合的第二限位平面5012。
通过第一限位平面404与第二限位平面5012的配合限位作用，可以限制气管4周向转动并在吸嘴3转动时引导气管4轴向上下移动。
所述引导机构5还包括套设于进气座501与气管4之间的密封座502，密封座502由硅胶制作而成。进气座501与密封座502卡扣相连，使得进气座501与密封座502密封连接且形成一体，方便组装；密封座502内壁具有与第一限位平面404相配合的第三限位平面5021。密封座502的设置，可以保证密封座502套接在气管4外部后进气座501和气管4组成的气路的密封性好，防止漏气。
雾化器还包括转盘6和压簧7，转盘6外壁与吸嘴3内壁固连，吸嘴3与转盘6铆接。吸嘴3与吸嘴座2外壁间隙配合，转盘6与吸嘴座2内壁间隙配合；压簧7和转盘6均套设于气管4外，压簧7底部设于转盘6上的限位槽601内， 压簧7顶部与气管4底端的限位凸缘405相抵接。
所述支撑部403的高度取值范围为1mm～15mm，所述延伸段301底端的厚度取值范围为3mm～8mm。借由该结构，气管4顶端与延伸段301底端之间形成一个空间容量较大的直径大于延伸段301内径的空腔31，从而烟雾在该空腔31内的流速相对缓慢，导致烟雾中的大颗粒液滴容易冷凝在该空腔31内，防止用户吸食到大颗粒烟油液滴，烟雾口感好且不会烫伤嘴部。冷凝在该空腔31内的烟油液滴还会顺着转盘6内壁流入转盘6与气管4之间的腔体32内，当该腔体32内的烟油液滴随着使用时间的增长而积存较多时，可以通过甩动吸嘴3将积存的烟油液滴甩出。
转盘6与吸嘴3固连并形成一个旋转体，吸嘴3与吸嘴座2外壁间隙配合，转盘6底部设置有凸台(未标注)，通过该凸台与吸嘴座2内壁卡接且间隙配合，从而可以保证旋转体绕吸嘴座2轴线360°旋转时不会脱落的现象。
压簧7的设置，可以保证支撑部403与台阶部3011的可靠抵接，保证调气功能能够实现。
所述外壳1内设有油仓8，所述吸嘴座2上开设用于向油仓8内注油的注油孔202。
由于吸嘴3、转盘6均与吸嘴座2间隙配合，旋转体转动时不会带动吸嘴座2转动。将吸嘴座2兼用作注油盖，调气过程不会误开注油盖。
所述气管4内还设有与吸嘴3连通的出气通道406，气管4侧壁上开设用于连通进气通道401与出气通道406的第三过气孔407，气管4内具有将出气通道406与进气通道401隔离的隔离层408，从而使得在气管4内的进气通道401和出气通道406完全密封隔离，烟雾被带出更加充分及烟雾口感饱满细腻。
各台阶部3011底面两侧具有与相邻台阶部3011底面平滑过度相连的倒斜角3012。倒斜角3012的设置使得支撑部403在调节进气各档位之间过度更加顺畅。
密封座502内壁开设四个卡槽5022，进气座501上具有与四个卡槽5022一一相配合的四个卡勾5013。
外壳1内还设有雾化套9，雾化套9顶端与进气座501固连。雾化套9与外壳1之间形成所述油仓8。
雾化套9内设有外套管10、杯状导油棉11与内套管12，导油棉11的侧壁套设于外套管10上段与内套管12下段之间。外套管10上开设连通油仓8与导油棉11的过油孔1001。
雾化器还包括超声雾化片13，超声雾化片13通过硅胶座30固设于外套管10下段内。导油棉11外底面与超声雾化片13的雾化面相接触。导油棉11内设有压棉弹簧14，压棉弹簧14的一端与内套管12相抵接，压棉弹簧14的另一端与导油棉11内底面相抵接，使得导油棉11与超声雾化片13接触可靠，保证导油顺畅。
外壳1底端通过底座15与底盖16相连。底盖16内设有螺纹环17，PCB18通过螺钉19固设于螺纹环17上。螺纹环17上还设有电极套20，电极套20通过弹性电极21与超声雾化片13电极层相抵接。弹性电极21通过导电片22与PCB18电连接。螺纹环17与电极套20之间通过绝缘环23绝缘连接。
内套管12与雾化套9之间设有第一密封圈24。外壳1与底座15之间设有第二密封圈25。外套管10与底座15之间设有第三密封圈26。雾化套9与外壳1之间设有第四密封圈27。吸嘴座2与油仓8之间设有密封垫28。底座15与底盖16之间设有压紧环29。
如图10所示，雾化器工作时，气流从进气孔201进入，依次通过第二过气孔5011、第一过气孔402、进气通道401达到导油棉11，将烟雾依次从第三过 气孔407、出气通道406和吸嘴3带入用户口腔。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是局限性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护范围之内。
