Description

一种雾化器及其电子烟 技术领域
本发明属于一种雾化器及其电子烟。
背景技术
目前已有的超声波高频雾化电子烟，其一般通过储油棉将油腔中的烟油传导至雾化片上，然后开设与雾化片的雾化表面相连通的进气通道和出气通道，通过高频振荡雾化烟油。但是现有的产品在实际应用过程中存在如下缺陷：
1.空气经过进气通道流至雾化表面后，由于空气是乱序进入，杂乱无章，并不是所有空气都流到雾化表面参与雾化了，大部分空气直接从出气通道流走，大大降低了雾化效率以及烟雾量。同时，冷空气夹杂着雾化的烟雾,将烟雾温度降低,使得入口温度低,口感差。
2.雾化片表面容易出现积油现象,特别是长时间不使用时，烟油会不断往下渗透，容易造成积油。积油会导致烟油难以雾化，出烟量少。
3.雾化片产生的热量很容易通过出气通道传导至外壳上，造成外壳发烫严重。
4.目前的出气通道一般是金属管，雾化后的烟雾在出气通道中流动一定距离后会产生冷凝现象，一定程度上减小了烟雾量，而且冷凝的烟油堆积多了会被吸入口中，影响用户体验。
发明内容
针对上述问题，本发明旨在提供一种雾化效率高、产生烟雾量大的雾化器及其电子烟。
本发明解决问题的技术方案是：一种雾化器,包括雾化器本体、安装在雾化器本体顶部的吸嘴组件、设置于雾化器本体上的进气口、设置于雾化器本体内的雾化片和油腔、可将油腔中的烟油导入雾化片的雾化面的导油体，雾化器本体内设有与进气口连通的第一进气道、以及与吸嘴组件连通的出气管道，所述导油体包括与雾化片的雾化面抵接的雾化棉，所述出气管道安装有导气结构，导气结构下端与雾化棉抵接，该导气结构包括紧贴雾化棉设置的导气通道，该导气通道同时与第一进气道和出气管道内腔连通。
上述方案中,导气通道的设计,使得从第一进气道进入的空气可以被引流,使 所有空气能够低空掠过雾化棉与雾化片接触的面,更充分的雾化,雾化效率更高,产生的烟雾更多,从而得到的烟雾浓度高，提升烟雾口感。
具体的，所述雾化器本体还包括壳体、安装在壳体底部的连接电极，所述吸嘴组件安装在壳体顶部，所述雾化片与连接电极之间电连接；
所述雾化棉为中空柱状结构，出气管道下端插入雾化棉的中空腔中。
一种优选的方案中，所述进气口设置于壳体下部、对应于雾化棉安装位置的区域段上，所述雾化棉下部设有与第一进气道连通的第一过气孔；
所述导气结构还包括设置于出气管道下端且带有中空腔的基体，该基体将雾化棉的中空腔封堵，基体下端从雾化棉内腔底部将雾化棉与雾化片抵紧，所述导气通道设置于基体下端，导气通道与第一过气孔及基体的中空腔相连通，所述基体的中空腔与出气管道连通。
进一步的，所述油腔底部通过第一密封座密封,第一密封座中间设有凹槽，凹槽内安装有第一隔油座；
所述第一隔油座为T字形，其包括第一竖直部、位于第一竖直部顶部的第一法兰边，所述第一竖直部插入凹槽中且与凹槽内壁之间留有第一间隙，所述第一间隙内设有储油棉，在第一法兰边上对应储油棉的位置开有与油腔连通的第一过油孔；
所述雾化棉包裹在第一竖直部的外壁，雾化棉外侧面与储油棉抵接；所述基体与第一竖直部固定连接。
所述导气通道的结构可以有多种：
一种具体的方案中，所述基体下端设有底部敞开的第一密封罩，第一密封罩的内腔设有底部敞开的第二密封罩，第一密封罩与第二密封罩之间留有间隙，第二密封罩的内腔与基体的中空腔连通；
在第一密封罩上与第一过气孔对应处开有第一导气槽，在第二密封罩上对应第一导气槽位置处开有第二导气槽；
第一导气槽、第二导气槽以及第一密封罩与第二密封罩之间的间隙形成导气通道；
所述第一密封罩和第二密封罩与雾化棉相抵接。
上述方案中，空气从第一进气道进入第一过气孔，然后流经第一导气槽、第 一密封罩与第二密封罩之间的间隙、第二导气槽，最终从基体的中空腔流出。第一导气槽和第二导气槽紧邻雾化棉与雾化片的接触部位，起到引流作用。
另一种具体的方案中，所述基体的中空腔直通基体底部，在基体底部设有将基体的中空腔封堵的封盖，该封盖上对应第一过气孔处设有第二过气孔，该第二过气孔即为导气通道；
所述封盖底部与雾化棉抵接，抵接位置处开有第三过气孔。
上述方案中，封盖在基体的中空腔底部，具有一定的弹性，使其抵接在雾化棉上时具有一定的变形空间，从而提高雾化棉与雾化片的接触效果，与此同时第二过气孔起到引流作用。
优选的，所述封盖为球形或倒锥形。
另一种优选的方案中，所述进气口设置于壳体上部，所述油腔中间设有容置腔,所述出气管道设置于容置腔内,且出气管道外壁与容置腔内壁之间留有间隙A,该间隙A与进气口连通,形成第一进气道；
所述出气管道下端靠近管口位置设有凸缘，所述导气结构包括套接于凸缘下方的出气管道管口处的柔性管，柔性管下端开有过气槽，柔性管的底部与雾化棉中空腔的底部相抵接；
所述出气管道插入雾化棉的中空腔后，凸缘上表面正对第一进气道的出口，且凸缘与第一进气道的出口之间留有第二间隙，所述凸缘侧面靠近雾化棉的中空腔内壁且与内壁之间留有第三间隙。
上述方案中，通过气路的设计，使得空气进入第一进气道之后，引导空气从第二间隙和第三间隙流过，从而保证空气能够沿着雾化棉的中空腔内壁流动，进而带走在雾化棉的拐角处产生的烟雾，避免烟雾的淤积，增加烟雾浓度。过气槽的设计,使得空气可以被引流,使所有空气能够低空掠过雾化棉与雾化片接触的面,更充分的雾化,雾化效率更高,产生的烟雾更多。
进一步的，所述油腔底部通过第二密封座密封,第二密封座中间设有凹槽，凹槽内安装有第二隔油座；
所述第二隔油座为T字形，其包括第二竖直部、位于第二竖直部顶部的第二法兰边，所述第二竖直部插入凹槽中且与凹槽内壁之间留有第四间隙，所述第四间隙内设有储油棉，在第二法兰边上对应储油棉的位置开有与油腔连通的第二过 油孔；
所述雾化棉侧面包裹在第二竖直部的外壁，该雾化棉侧面与储油棉抵接。
所述雾化棉底部开有第一出气孔。
为使得雾化棉与雾化片接触更紧密，所述第二竖直部下端套接有弹簧，该弹簧被雾化棉包裹，弹簧下端与雾化棉底部内表面抵接，所述出气管道下端穿过第二隔油座、插入弹簧的中心孔，且柔性管与第一出气孔连通。
进一步的，所述柔性管为玻纤管，其包括套装在出气管道下端的第一玻纤管、以及套装在第一玻纤管外壁上部的第二玻纤管；
所述第二玻纤管长度小于第一玻纤管长度，所述过气槽开设于第一玻纤管下端沿。
第二玻纤管主要是增强第一玻纤管的强度，防止在组装时被压弯。
进一步的，所述出气管道内腔下部设有滤网。该滤网用于阻挡雾化片在工作时烟油飞溅或大颗粒烟雾被吸入用户口中。
再一种优选的方案中，所述进气口设置于壳体上部，所述油腔中间设有隔油腔，隔油腔内设有容置腔,所述出气管道设置于容置腔内,且出气管道外壁与容置腔内壁之间留有间隙B,该间隙B与进气口连通,形成第一进气道；
所述导气结构包括套接于出气管道内腔并兼有隔热和吸油性能的内衬管，出气管道下端与雾化棉中空腔的底部之间留有间隙C，内衬管下端伸出出气管道下端并与雾化棉中空腔的底部抵接，内衬管下端边沿开有与第一进气道连通的过气孔F，所述过气孔F为导气通道。
上述方案中，过气孔F的设计,使得空气可以被引流,使所有空气能够低空掠过雾化棉与雾化片接触的面,更充分的雾化,雾化效率更高,产生的烟雾更多。
内衬管本身具有隔热功能，且气管下端不与雾化棉接触，可防止雾化片产生的热量经过气管传递到外壳。
另外，内衬管具有吸油性能，当烟雾流到气管上部发生冷凝时，可将冷凝的烟油吸附，并自上而下再次导入雾化棉进行二次雾化，避免冷凝的烟油被吸入口中导致影响口感。
进一步的，所述过气孔F孔高为0.2mm～0.7mm。所留的过气孔较小,使得空气可以被引流,使所有空气能够从这细小的缝隙中低空掠过雾化棉与雾化片接触 的面,更充分的雾化。
具体的，所述容置腔由外套管和套接在外套管内腔的内套管组成，所述外套管包括设置于油腔底部，用于密封油腔的中空的第三密封座、固定于第三密封座上的竖直管，所述内套管套接于竖直管的内腔，内套管的内腔即为容置腔；
所述第三密封座的中空腔中设有雾化片固定座，雾化片固定于雾化片固定座上；
所述雾化棉侧壁被夹持固定于内套管外壁和竖直管内壁之间；所述竖直管下端对应雾化棉侧壁处设有多个第三过油孔，所述第三过油孔与油腔相连通；
带有内衬管的出气管道从内套管的中空腔中插入直达雾化棉的中空腔。
进一步的，在竖直管的外壁上对应第三过油孔位置处套接有储油棉，该储油棉位于油腔内并将第三过油孔封盖住。储油棉的作用在于可以控制烟油传递速率,防止雾化棉吸油过多而产生积油。
为使得雾化棉与雾化片接触更紧密，所述内套管内腔下部套接有弹簧，该弹簧下端与雾化棉底部内表面抵接，带有内衬管的出气管道从内套管的中空腔中插入，并插入弹簧的中心孔中。
进一步的，所述出气管道与内衬管上端平齐，内衬管上端设有滤网。该滤网用于阻挡雾化片在工作时烟油飞溅或大颗粒烟雾被吸入用户口中。
进一步的，所述内衬管为玻纤管，其过气孔F为围绕内衬管下端边沿开设的锯齿形槽或波浪形槽。
为了更好的隔热，所述出气管道与雾化棉中空腔的底部之间的间隙C高度大于2mm。出气管道下端不与雾化棉接触，可防止雾化片产生的热量经过出气管道传递到外壳。
一种改进的方案中，所述内衬管上端伸出出气管道上端，并延伸至吸嘴组件内腔，内衬管外壁与吸嘴组件内腔壁之间留有间隙D；
所述吸嘴组件与壳体顶部之间可拆卸连接。
将内衬管直接向上延伸至吸嘴，吸嘴为塑胶或木材等其他非金属材质，这样整个出气通道可以大大减少冷凝现象的发生。设置间隙D的目的在于方便吸嘴拆装。
进一步的，所述雾化片下表面与连接电极之间设有隔热片。隔热片可以避免 雾化片的热量从下方传递到连接电极以及外壳。
优选的，所述雾化片为实心压电陶瓷片。
相应的，本发明还提供一种电子烟，包括外部电源，及上述方案所述的雾化器，外部电源与雾化器的连接电极连接。
本发明通过在现有技术的基础上增加导气通道结构，使得进入的空气能够被正确引流，从而使所有空气能够低空掠过雾化棉与雾化片接触的面,更充分的雾化,雾化效率更高,产生的烟雾更多。这样也避免了部分冷空气直接从气管流走而与烟雾混合后降低烟雾温度，避免了烟雾温度低影响口感的现象。
