Description

一种超声雾化体及制备方法、雾化芯及雾化器 技术领域
本发明属于电子烟技术领域，特别涉及一种超声雾化体及制备方法、雾化芯及雾化器。
背景技术
目前已有超声波电子烟，已有的高频超声波电子烟存在容易泡油不出雾、烟雾带出不够充分、空间利用率不高、且容易吸入大颗粒烟雾。
现有高频超声波电子烟所采用的雾化片都是圆片状压电陶瓷。
中国专利 CN201610145881.5公开了一种电子烟雾化器及电子烟，雾化器包括吸嘴和油杯，所述油杯与所述吸嘴之间设置有雾化腔连接；雾化腔由上盖和底座盖合形成；雾化腔内固定有第一发热体；第一发热体与储油片接触；储油片与油杯内的导油结构顶端接触；上盖上开设有至少一个与吸嘴腔连通的出气孔。第一发热体工作时，将液体雾化形成烟雾，与此同时雾化腔内的空气也被第一发热体加热使得雾化腔内的空气受热膨胀，此时雾化腔内形成一个高温高压的腔体，从而使烟雾与已经加热的空气在雾化腔内混合，之后进而从出烟油雾通道自动喷出；由于雾化腔内烟雾是与已经加热的空气混合雾化的，因此烟雾口感细腻。
中国专利 CN201610160216.3公开了一种超声波雾化器及电子烟，超声波雾化器包括雾化片和用于将液体导入到所述雾化片上表面的导液结构；所述导液结构与储液腔连通；所述雾化片上表面与气流通道相通；所述雾化片包括压电陶瓷层和用于驱动所述压电陶瓷层振动的导电体。该雾化片上不需要设置微孔喷出雾化气体，因此不会发生雾化气体颗粒较大堵塞微孔而无法喷出雾化气体的情况，同时可以更好地防止雾化器液体泄漏。
上述专利存在的问题如下：
1.油路不好控制，容易出现泡油不起雾现象；
2.气路只能从表面走，带出的烟雾不够充分；
3.径向占用尺寸空间比较大，使雾化器整体空间利用率不高，尺寸很难做小；
4.大颗粒烟雾会垂直雾化片表面方向往上喷，容易喷如使用者口 腔，严重时会烫伤口腔。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种超声雾化体及制备方法、雾化芯及雾化器，结构简单，能够对烟油超声雾化产生烟雾，烟雾口感好，烟雾量大，使用成本低；可以解决现有雾化器泡油不起雾、大颗粒直接喷入口腔、烟雾带出不充分、空间利用率不高的问题。
为解决上述技术问题，本发明所采用的技术方案是：
一种超声雾化体，其结构特点是包括超声雾化管，所述超声雾化管的内外侧面均涂覆导电层，超声雾化管的内侧面和/或超声雾化管的外侧面为雾化面。
借由上述结构，超声雾化管形成具有一定刚度的发热体和径向振荡体，超声雾化管径向的振荡会使得与其雾化面接触的导油棉上的烟油也产生高频振荡即生产烟雾供用户吸食。同时，由于超声雾化管自身存在阻抗，在通电时会产生热量，超声雾化管自身产生的热量会传导至烟油，从而也加热烟油并产生烟雾。再者，以高频振荡的声波形式将烟油内部的分子振碎，从而使烟油内部的分子更容易受热且受热更均匀，促使出烟速度更快。利用高频振荡方式对烟油进行超声雾化和加热，使烟油被超声雾化生产烟雾，同时也使烟油从内部到外壁加热充分、均匀，不会出现局部温度过高的现象，不会烧焦导油棉，烟雾口感好，烟雾量大，使用成本低，空间利用率高。
基于同一个发明构思，本发明还提供了一种超声雾化体的制备方法，其包括如下步骤：
S1、将坯料压制成超声雾化体的形状并烧结呈筒状的瓷体；
S2、在瓷体的表面上设置有导电电极使超声雾化体具有压电性能；
S3、从超声雾化体的外表层电极和超声雾化体的内表层电极各引出电子线或电极，该电子线或电极用于与外部电极电连接；优选在超声雾化体的内壁表面镀釉层。
优选地，步骤S1中，坯料为锆钛酸铅制成。
优选地，步骤S2中通过银层烧渗、化学沉积或真空镀膜在瓷体的表面上设置导电电极。由此，通过在与导油棉接触的电极表面上再镀一层釉层，可以防止该电极被烟油腐蚀。

由此，本发明将通过超声雾化体对烟油进行雾化，进而改变其导油导气方式，工作时，超声雾化体工作时其内孔表面将烟油雾化形成烟雾，即烟雾向雾化内孔的径向方向喷射，同时气流穿过内孔将烟雾带出，烟雾带走的更加充分，使烟雾更加大，彻底解决了现有雾化器泡油不起雾、大颗粒直接喷入口腔、空间利用率不高、烟雾带出不充分等问题。

优选地，所述底座侧壁上开有进气口，该进气口与所述进气通道连通；优选所述进气口处装由调节进气量大小的调气环。

优选地，所述超声雾化体为中空圆柱管，所述出气通道的进气口延伸至超声雾化体的中空腔内。超声雾化体超声雾化烟油时所产生的烟雾经过所述超声雾化体的中空腔内，使得在中空腔中的烟雾受到超声雾化体工作时产生的热量再次加热，使得烟雾口感更加细腻，提升用户体验。

优选地，所述底座中部设有通孔，所述通孔内通过绝缘环固定有与超声雾化体电连接的内电极。
作为本装置的一种实施方式，所述超声雾化体的外侧面为雾化面，所述外管与超声雾化体雾化面之间设有第二间隙，所述第二间隙形成雾化腔，所述雾化腔的下端设有出气槽，所述出气槽的下方安装有固定座，所述固定座在出气槽下方开设有用于收集冷凝在所述雾化腔内壁烟液滴的凹槽，所述固定座的凹槽内设有第二储油层，所述导 油层的下端与第二储油层连接。在超声雾化体工作时，雾化导油层上的烟油喷出烟雾撞击在外管内壁上,烟雾和内壁发生撞击使烟雾分子进一步的打碎或打散，小分子烟雾被用户吸烟的气流带至用户口腔保证用户口感，同时在内壁上冷凝的烟油顺着内壁往下流至第二储油层上，第二储油层将冷凝后的烟油被导油层吸收再次超声雾化，同时也可以防止大颗粒烟雾或冷凝烟液滴被吸到用户口中，影响用户口感。
具体地，所述出气通道的进气口上设有朝下方延伸的进气管。也就是说出气通道的进气口端设置有延伸至超声雾化体的中空腔内的进气管，防止超声雾化体内侧形成的冷凝烟液滴顺着中空腔内壁在用户吸烟时往吸嘴组件移动，最后使用户容易吸到烟油，影响用户体验。
优选地，所述固定座凹槽的外边缘的垂直高度不低于所述出气槽的出气口的垂直高度，以使形成阶梯式气流通道，从而有利于冷凝烟油的存储。

作为本装置的另一种实施方式，所述超声雾化体的内外两侧均为雾化面。这样内壁和外壁均用于雾化烟油，可以生产更多的烟雾满足大烟雾量用户的需求。

2.超声超声雾化体的内孔设置有弹性件(弹簧)，该弹簧用于支撑导油棉，使导油棉与超声超声雾化体内孔的内壁接触，防止超声超声雾化体工作时与导油棉接触不良而产生烧焦或自身损坏的现象。
3.导油棉通过雾化芯外套管上的通孔吸收烟油仓内的烟油，导油棉沿着靠近吸嘴端的雾化芯弯折延伸至超声超声雾化体内孔，有效的防止烟油流动速度太快而影响雾化效果。
4.雾化器的底端处设置有储气腔，进气口设置在储气腔侧壁上并与大气连通，防止用户在使用电子烟时手指堵住进气口，也可以用于将储存在雾化芯遗漏下来的烟油，防止该烟油渗漏到电子烟的电源部分而损坏电源。
5.吸嘴上设置有喇叭形的气管结构，方便该气管更好的将冷凝烟油向下流动，也可以很好的防止用户吸到冷凝烟油。
6.油腔设置在超声雾化体上端，由于烟油的重力作用，使超声雾化体雾化烟油时导油层上的烟油充足，雾化效率更高。
7.超声雾化体为中空结构，超声雾化体下端设置有第二储油层，主要用于吸收冷凝在外管小端部内壁上的烟液滴，既可以回收重新利用冷凝烟油，又可以防止用户吸食到冷凝烟油，提升烟雾口感及用户体验。

S2、在瓷体的表面上设置有导电电极，即可以通过银层烧渗、化学沉积和真空镀膜等方法，同时高压极化使陶瓷具有压电性能。
S3、外表层电极2031和内表层电极2032各引出电子线或电极，使其与外部电极连接方便。另外用于与导油棉接触的电极表面上再镀一层釉层，防止该电极被烟油腐蚀。

为了防止冷凝烟油被用户吸入，所述连接环2016具有上端口径大于下端口径的喇叭形通道。
为了防止用户堵住进气口，导致烟油雾化后无法被吸入，所述雾化座2010与底座2024之间形成储气腔2027。
所述底座2024下端装有电极环2013，该电极环2013通过装设在雾化座2010内的雾化芯电极环2012与所述至超声雾化体205电连接，且该雾化座2010与雾化芯电极环2012之间通过雾化芯绝缘环2011隔开。为了防止漏电，所述电极环2013外套装有绝缘环2025。

由此，本发明的超声波雾化器包括超声超声雾化体，雾化芯内设置有超声雾化体，该超声超声雾化体内孔表面用于雾化烟油，当该超声超声雾化体工作时内孔表面将烟油雾化形成烟雾，即烟雾向雾化内孔的径向方向喷射，同时气流穿过内孔将烟雾带出。气流的方向与超声喷出烟雾方向的垂直，以使质量轻颗粒小的烟雾被气流带至吸嘴处 供用户吸食，提高烟雾口感；同时可很好的杜绝大颗粒直接往上喷烫伤口腔的问题；
如图10所示，雾化芯的组装步骤为：首先将超声雾化体插入硅胶套内孔，使整个硅胶包裹超声雾化体，再将整个硅胶套组件插入雾化芯外套管内孔中，之后将导油棉中间柱状插入超声雾化体中间孔里，再将弹簧插入导油棉中间孔，将绝缘环装入雾化芯外套管底孔中，使超声雾化体一极电子线在绝缘环外侧,使其与内套管内壁卡紧，另一极在绝缘环内孔侧，再将电极环装入绝缘环内孔中，将超声雾化体一极电子线与绝缘环内控壁卡紧，将雾化芯外套管罩设在导油棉的表面上，最后通过雾化芯外套管涨紧配合后得到的雾化芯。
超声超声雾化体的内孔设置有弹性件(弹簧)，该弹簧用于支撑导油棉，使导油棉与超声超声雾化体内孔的内壁接触，防止超声超声雾化体工作时与导油棉接触不良而产生烧焦或自身损坏的现象。
导油棉通过雾化芯外套管上的通孔吸收烟油仓内的烟油，导油棉沿着靠近吸嘴端的雾化芯弯折延伸至超声超声雾化体内孔，有效的防止烟油流动速度太快而影响雾化效果。
雾化器的底端处设置有储气腔，进气口设置在储气腔侧壁上并与大气连通，防止用户在使用电子烟时手指堵住进气口，也可以用于将储存在雾化芯遗漏下来的烟油，防止该烟油渗漏到电子烟的电源部分而损坏电源。
吸嘴上设置有喇叭形的气管结构，方便该气管更好的将冷凝烟油向下流动，也可以很好的防止用户吸到冷凝烟油。
所述弹簧用于固定导油棉，确保导油棉与超声雾化体的内腔表面良好接触。
所述超声雾化体的内壁为主要电极，用于超声雾化烟油，另外，其中通结构可以将气流设为下进气，气流从底部进入，再从超声雾化体中通结构由下往上出气，可以更加充分的将烟雾带出，使烟雾更大。
所述硅胶套起到隔绝热量的作用，因为超声雾化体工作时会产生一定的热量，通过硅胶套可将热量隔绝，避免雾化器发烫。此外硅胶套起到密封烟油作用，避免超声雾化体外环面接触烟油，腐蚀银层。所述导油棉用于将烟油从雾化芯进油孔导到超声雾化体内环面。
由此，本发明的烟油经进油孔进入导油棉，往上导油，从硅胶套上方经过再往超声雾化体内壁往下导油，经过数次拐弯后，可以很好的防止超声雾化体渗油过快，造成泡油不出雾的问题。
本发明中气路可以从超声雾化体中间通孔进出，烟雾带走的更加充分，使烟雾更加大。
本发明的径向尺寸可做得更小巧，空间利用率更高。
由于雾化时主要雾化面在于超声雾化体内表面，可很好的杜绝大颗粒直接往上喷烫伤口腔的问题。
本发明的压电陶瓷雾化器为中通环状结构，截面可为圆形结构、如图15所示的椭圆形结构、如图16所示的方形结构。

1.超声雾化体采用椭圆形中通形状。
2.硅胶套2019与超声雾化体205只有首尾两处配合，中间一留有空间，有利于隔绝热量，避免温度导出到雾化器外壳2026，造成发烫。
