Description

一种超声波电子烟雾化器 技术领域
本发明属于电子烟技术领域，特别涉及一种超声波电子烟雾化器。
背景技术
现有的超声波电子烟雾化器包括超声雾化片、雾化棉、油腔、进气管、出气道和吸嘴，其中，雾化棉连通油腔并与超声雾化片的雾化面相接触，出气道的入口与超声雾化片的雾化区域相对，出气道的出口与吸嘴相连通。进气管、超声雾化片的雾化区域、出气道、吸嘴依次连通。
现有的超声波电子烟雾化器具有以下缺点：
第一，由于超声雾化片的雾化区域与出气道入口相对，因而超声雾化片雾化产生的大颗粒烟油珠容易顺着出气道侧壁或气流直接喷溅进入用户口腔，导致用户吸食到烟油，用户体验差。
第二，进气管为内径一致的圆柱形直管，气流流经进气管时速率均匀，气流在进气管出气端流出时对雾化棉不会有太大的冲击力，因而雾化棉中心区域积聚的烟油不会被冲击分散至边缘区域，超声雾化片在工作之初容易泡油，启动速度慢，抽吸之初烟雾量不稳定，甚至出现前几口没有烟雾的现象。
第三，为了使得雾化棉与超声雾化片紧密接触，通常设置压棉弹簧，将雾化棉压紧在超声雾化片上。在现有技术中，压棉弹簧的一端与雾化棉相抵接，压棉弹簧的另一端与出气管上的凸台相抵接，压棉弹簧与出气管的入口相对。当压棉弹簧上积有油珠时，油珠容易被气流经出气管带入用户口腔中，从而产生吸食到烟油的现象，容易烫伤口腔，烟雾口感差，影响用户体验。
第四，在超声雾化片高频振荡时，容易把雾化棉振烂或振出破孔，雾化棉的寿命低，影响导油和雾化效果，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，提供一种改进了的超声波电子烟雾化器，超声雾化片不易泡油，启动速度快，烟雾量稳定，用户不易吸食到烟油，烟雾口感好；能够防止雾化棉被振烂，提升雾化棉使用寿命，导油和雾化效果好，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：
一种超声波电子烟雾化器，包括超声雾化片、雾化棉、油腔、进气管、出气道和吸嘴，其中，雾化棉连通油腔并与超声雾化片的雾化面相接触，进气管的入口与外界相连通，进气管、超声雾化片的雾化区域、出气道、吸嘴依次连通，其结构特点是进气管的出口与超声雾化片的雾化区域相对。
由于进气管的出口与超声雾化片的雾化区域相对，因而进气管中的进气气流方向与超声雾化片雾化烟油形成烟雾喷出的方向相反，所以烟雾中的大颗粒烟油珠被气流带回至超声雾化片雾化区域进行再次雾化，含有细小颗粒的烟雾随气流流动供用户吸食，防止用户吸食大颗粒烟油珠并烫伤口腔，提高烟雾口感及烟油利用率和使用成本。
作为一种优选方式，进气管进气端的内径大于进气管出气端的内径。
借由上述结构，由于进气管进气端的内径大于进气管出气端的内径，因而当有气流流经进气管时，由于出气端的内径小，所以气流流速较快，所以快速流动的气流对超声雾化片有较大的冲击力，可以将雾化棉中心积累的烟油吹向边缘，避免超声雾化片出现泡油现象，有利于提高超声雾化片雾化烟油的速度，出烟速 度快且烟雾量稳定，避免出现因泡油现象而引起的抽吸前几口没有烟雾或烟雾量小的情况。
进一步地，所述进气管为锥形管。
进一步地，还包括上盖，上盖顶端与吸嘴相连，上盖底端与下盖相连，下盖底部连有底盖；超声雾化片通过底盖内的雾化座固定，上盖内设有油腔、内套管和外套管，雾化棉侧壁套设于内套管与外套管之间，进气管通过转换头与吸嘴相连。
进一步地，还包括第一导气管和第二导气管，所述内套管内侧壁与进气管下段之间形成空腔，第一导气管上段与转换头相连，第二导气管上段与连接套相连，第一导气管的下段和第二导气管的下段均伸入在所述空腔内，第一导气管的下段和第二导气管的下段均不与空腔内壁接触；第一导气管外侧壁与第二导气管内侧壁之间形成过气道，空腔与过气道形成所述出气道。
借由上述结构，由于第一导气管下段与第二导气管下段均悬空伸入空腔内，第一导气管下段与第二导气管下段均不与空腔内壁相接触，所以能够阻挡冷凝在该空腔壁上的大颗粒烟油珠随第一导气管下段与第二导气管下段的外壁进入用户口腔，由于过气道的截面积小于空腔的截面积，所以在吸烟时经过该过气道的烟雾受到挤压，因此有部分烟雾中的大颗粒烟油珠被挤压撞击在空腔壁上形成冷凝烟油珠，从而也可以防止大颗粒烟油珠被吸食到用户口腔，用户体验好。
作为一种优选方式，所述雾化棉为杯状，雾化棉的侧壁套设于内套管与外套管之间，雾化棉的外底面与超声雾化片的雾化面相接触。
进一步地，还包括压棉弹簧，所述压棉弹簧的一端与雾化棉的内底面相抵接，压棉弹簧的另一端与内套管相抵接。
压棉弹簧可以使得雾化棉与超声雾化片接触紧密，提升雾化效果。
进一步地，还包括导油棉，所述导油棉套设于内套管与雾化棉之间。
雾化棉内侧壁与导油棉相接触，当油腔内烟油充足时，导油棉内储存一定量的烟油，所以导油棉内储存的烟油通过雾化棉导至超声雾化片加热雾化，用户在不方便添加烟油时也可以进行短时间的抽吸，防止超声雾化片干烧和提高使用的便利性。
进一步地，所述底盖底部设有螺纹盖封口，螺纹盖内设有下电极，螺纹盖与下电极之间通过绝缘环绝缘相连。
进一步地，所述吸嘴与上盖之间设有密封垫，所述下盖与上盖之间设有密封圈。
进一步地，所述进气管外侧壁底部设有用于阻挡大颗粒烟雾的阻挡部。
当超声雾化片高频振荡雾化烟油生产烟雾喷出时，阻挡部遮挡垂直超声雾化片喷出的烟雾，此时烟雾中的大颗粒烟油珠被阻挡部遮挡及凝结在遮挡部上，其他细小颗粒的烟油珠即烟雾随气流拐弯进入用户口腔，防止大颗粒烟雾进入用户口腔，提升用户吸食烟雾的口感。
进一步地，还包括压棉弹簧，所述压棉弹簧的一端与雾化棉相抵接并使雾化棉与超声雾化片紧密接触，压棉弹簧的另一端与进气管端部的凸台相抵接。
压棉弹簧设置在进气管端部，一方面，可用于压紧雾化棉，使雾化棉与超声雾化片紧密接触，导油连续，防止超声雾化片出现干烧的现象；另一方面，由于压棉弹簧设置在进气管出口端，因而凝聚在压棉弹簧上的由超声雾化片工作时喷出的大颗粒烟油珠会随气流掉落至超声雾化片上再次加热雾化，防止大颗粒烟油珠进入用户口腔，防止用户烫伤口腔，烟雾口感细腻，用户体验好，烟油利用率高。
进一步地，还包括用于防止雾化棉被振烂的垫网层。
垫网层可以加固或隔离雾化棉，防止雾化棉被超声雾化片的高频振荡振烂，延长雾化棉的使用寿命，导油和雾化效果好，防止用户吸食到被振碎的雾化棉碎絮而影响身体健康，用户体验好。
作为一种优选方式，所述雾化棉上与超声雾化片相对应的位置设有两层棉片，所述垫网层夹设于该两层棉片之间；
或者，所述雾化棉上与超声雾化片相对应的位置为单层棉片，所述垫网层内嵌于该单层棉片内。
若垫网层夹设于两层棉片之间，使这两层棉片均得到加固作用，防止在超声雾化片高频振荡时对雾化棉产生冲击而使雾化棉破损。
若垫网层内嵌于单层棉片内，起到固定雾化棉的作用。
作为另一种优选方式，所述垫网层夹设于雾化棉与超声雾化片之间。
当垫网层夹设于雾化棉与超声雾化片之间时，雾化棉与超声雾化片间接接触，即雾化棉与超声雾化片之间有微小间隙，当超声雾化片高频振荡时所产生的冲击力先冲击垫网层，然后再通过垫网层传到雾化棉，此时雾化棉所受到的冲击力减少，使雾化棉不易破损，延长雾化棉的使用寿命。
作为一种优选方式，所述棉片的厚度为0.1～0.8mm。
棉片的厚度为0.1～0.8mm，优选为0.1～0.4mm，有利于导油量和出烟量，提高用户体验。
作为一种优选方式，所述垫网层的厚度为0.05～0.3mm。
与现有技术相比，本发明中的超声雾化片不易泡油，启动速度快，烟雾量稳定，用户不易吸食到烟油，烟雾口感好；又能够防止雾化棉被振烂，提升雾化棉使用寿命，导油和雾化效果好，提升烟雾口感，用户体验好。

具体实施方式
实施例一
如图1至图5所示，超声波电子烟雾化器实施例一包括超声雾化片1、雾化棉3、油腔2、进气管6、出气道7和吸嘴8，其中，雾化棉3连通油腔2并与超声雾化片1的雾化面相接触，进气管6的入口与外界相连通，进气管6、超声雾化片1的雾化区域、出气道7、吸嘴8依次连通，进气管6的出口与超声雾化片1的雾化区域相对，即超声雾化片1对烟油高频振荡生产烟雾喷出方向正对着进气管6的出口，所以在吸烟时进气气流克服烟雾喷出力使烟雾随气流一起流动。
本实施案例中，进气管6进气端的内径大于进气管6出气端的内径，使得进气管6进气端的气流流速小于进气管6出气端的气流流速。本实施案例的最优方案为所述进气管6为锥形管，进气管6内径过度顺滑，流速均匀变化，最后进气管6出气端的气流流速稳定，进而保证烟雾量的效果。超声雾化片1为压电陶 瓷式雾化片，且为实心的压电陶瓷式雾化片即烟油在该超声雾化片1表面被雾化；当通电后该压电陶瓷式雾化片产生高频振荡将表面上的烟油雾化生产烟雾，高频振荡的频率为2.2MHz—3.2MHz，优选为2.4MHz—2.6MHz。
本实施案例中，超声波电子烟雾化器还包括上盖10，上盖10顶端与吸嘴8相连，上盖10内设有油腔2，吸嘴8可以在上盖10上转动；可以转动吸嘴8将上盖10的注油孔(未标注)打开即可往油腔2内注射烟油。上盖10底端与下盖11顶部铆接相连以至于上盖10内的油腔2密封更好，同时下盖11底部连有底盖17；超声雾化片1通过底盖17内的雾化座19固定，上盖10内设有内套管15和外套管16，外套管16的侧壁上开设有进油孔(未标注)，雾化棉3套设于内套管15与外套管16之间，所以雾化棉3通过进油孔(未标注)与油腔2连通，雾化棉3的底端与超声雾化片1抵接；进气管6的一端通过转换头13与吸嘴8相连，进气管6的另一端插入内套管15的内腔，并且与超声雾化片1高频振荡雾化出来的烟雾接触，所以从进气管6进来的气流可以与烟雾混合。
本实施案例中，超声波电子烟雾化器还包括第一导气管23和第二导气管24，所述内套管15内侧壁与进气管6下段之间形成空腔25，超声雾化片1设置在空腔25底部，当超声雾化片1高频振荡雾化烟油生产烟雾时，烟雾被喷射到该空腔25内；第一导气管23上段与转换头13相连，第二导气管24上段与连接套14相连，第一导气管23的下段和第二导气管24的下段均伸入在所述空腔25内，第一导气管23的下段和第二导气管24的下段均不与空腔25内壁接触；第一导气管23外侧壁与第二导气管24内侧壁之间形成过气道26，空腔25与过气道26连通且形成所述出气道7。在吸烟时，气流从进气管6进入到该空腔25内与烟雾混合，然后形成的烟雾气流从过气道26排出至用户口腔；因此在吸烟的过程中，超声雾化片1高频振荡飞溅出来的大颗粒烟油珠收到进气流的冲击而凝结或冷凝在该空腔25的内壁上，因此可以防止用户吸食到烟油珠的现象。图1中箭头所示方向为气流走向。
本实施案例中，为了组装方便快捷以及烟油导流至超声雾化片1的雾化面均匀且导油连续性更好，所以优选方案为所述雾化棉3为杯状，杯状雾化棉3的底部抵接于超声雾化片1的雾化面，所以雾化棉3将油腔2内的烟油引导至超声雾化片1的雾化面参与雾化；杯状雾化棉3的顶部套设于内套管15与外套管16之间，以此固定雾化棉3，且使雾化棉3与油腔2有效连通；雾化棉3的外底面与超声雾化片1的雾化面相接触，接触面积小于雾化面的面积，提高超声雾化片1的雾化速率。如图2结构所述及图2中箭头所示方向为油路走向。
本实施案例中，超声波电子烟雾化器还包括压棉弹簧5，所述压棉弹簧5的一端与雾化棉3的内底面相抵接，压棉弹簧5的另一端与内套管15相抵接，压棉弹簧5的形状也为杯状，有效的将压棉弹簧5设置在杯状雾化棉3的内壁且与杯状雾化棉3紧密相接，从而保证杯状雾化棉3底部与超声雾化片1的雾化面接触面积以及可以防止杯状雾化棉3在组装过程中发生变形的现象。
本实施案例中，超声波电子烟雾化器还包括导油棉9，所述导油棉9环形套设于内套管15与雾化棉3之间，以使雾化棉3缓存更多的烟油，防止在组装雾化棉3的过程中雾化棉3顶部褶皱而影响导油速率。
本实施案例中，所述底盖17底部设有螺纹盖20封口，螺纹盖20内设有下电极21，螺纹盖20与下电极21之间通过绝缘环22绝缘相连。
本实施案例中，所述吸嘴8与上盖10之间设有密封垫12，所述下盖11与上盖10之间设有密封圈18，以及其他部件连接之间均设置有密封圈用于密封。
实施例二
图6中示出超声波电子烟实施例二的结构，实施例二与实施例一结构类似，区间仅在于，所述进气管6外侧壁底部设有用于阻挡烟雾中大颗粒烟油珠的阻挡部62，在本实施例中，阻挡部62为设置在进气管6外侧壁下段的螺旋状挡板。
阻挡部62位于超声雾化片1雾化烟油产生烟雾喷出的方向，因此烟雾喷至该阻挡部62，从而使烟雾中大颗粒烟油珠被阻挡部62遮挡且凝结在该阻挡部62的表面上，最后积累足够多的大颗粒烟油珠集聚起来且在自身重力引导下沿螺旋状挡板向下流动，并最终滴落到雾化棉3上再次参与雾化；阻挡部62也可以改变气流方向，使其他烟雾随气流流动的方向发生了改变，以至降低烟雾中大颗粒烟油珠。
对于实施例二中与实施例一相同的结构，在此不做文字赘述，但并不影响本领域的技术人员对本发明的理解和实现。
实施例三
如图7和图8所示，在第三种结构中，超声波电子烟雾化器包括超声雾化片1、雾化棉3、油腔2、进气管6、出气道7和吸嘴8，其中，雾化棉3连通油腔2并与超声雾化片1的雾化面相接触，进气管6的入口与外界相连通，进气管6、超声雾化片1的雾化区域、出气道7、吸嘴8依次连通，进气管6的出口与超声雾化片1的雾化区域相对。
在本实施案例中，超声波电子烟雾化器还包括压棉弹簧5，所述压棉弹簧5的一端与雾化棉3相抵接并使雾化棉3与超声雾化片1紧密接触，压棉弹簧5的另一端与进气管6端部的凸台61相抵接，在超声雾化片1工作时，烟油被超声雾化片1高频振荡雾化成烟雾，在此过程中有部分烟油飞溅至进气管6出口的内外侧壁，所以进气管6的内外侧壁和压棉弹簧5均粘附有烟油珠，当有气流从进气管6进入时，气流会将凝结在进气管6的内外侧壁和压棉弹簧5上的烟油珠以压棉弹簧5为导向吹向雾化棉3，重新被雾化棉3吸收，此过程中可以防止烟油珠飞溅到用户口腔而影响烟雾口感；进气管6的出口依次通过压棉弹簧5、出气道7与吸嘴8相连通，将烟雾带至用户口腔供其吸食。图7中箭头所示方向为气流走向。
在本实施案例中，所述雾化棉3为杯状，所述雾化棉3的外侧壁与油腔2相连通。
在本实施案例中，超声波电子烟雾化器还包括导油棉9，所述雾化棉3的内侧壁与导油棉9相接触，以使雾化棉3缓存更多的烟油，防止在组装雾化棉3的过程中雾化棉3顶部褶皱而影响导油速率。
在本实施案例中，超声波电子烟雾化器包括超声雾化片1和与油腔2相连通的雾化棉3，雾化棉3与超声雾化片1的一面相接触，由于在超声雾化片1高频振荡的过程中，对杯状雾化棉3的底部也产生高频振荡，所以杯状雾化棉3的底部很容易就被振烂，因此在杯状雾化棉3的底部垫上垫网层4，通过该垫网层4加固杯状雾化棉3的底部或将杯状雾化棉3的底部与超声雾化片1的接触面隔离(小间隙隔离)，以此保护杯状雾化棉3的底部被振烂的现象。
在本实施案例中，超声雾化片1为压电陶瓷式雾化片，且为实心的压电陶瓷式雾化片，即烟油在该超声雾化片1表面被雾化；当通电后该压电陶瓷式雾化片产生高频振荡将表面上的烟油雾化生产烟雾，高频振荡的频率为2.2MHz—3.2MHz，优选为2.4MHz—2.6MHz。
在本实施案例中，防止所述雾化棉3底部被振烂的一种优选方案为所述雾化棉3上与超声雾化片1相对应的位置设有两层棉片，所述垫网层4夹设于该两 层棉片之间。所述棉片的厚度为0.1～0.8mm，优选的厚度为0.1～0.4mm。所述垫网层4的厚度为0.05～0.3mm。
超声波电子烟雾化器包括相互连接的上盖10和下盖11，吸嘴8与上盖10顶端固连，吸嘴8与上盖10之间设有密封垫12。
进气管6顶端通过转换头13与吸嘴8固连。
上盖10内设有连接套14。连接套14内设有内外相互套接的内套管15和外套管16。雾化棉3侧壁与导油棉9夹设于内套管15与外套管16之间。
下盖11底端连有底盖17。下盖11与底盖17之间设有密封圈18。
超声雾化片1通过底盖17内的雾化座19固定。
底盖17底部设有螺纹盖20封口。
螺纹盖20内设有下电极21。下电极21与螺纹盖20之间通过绝缘环22绝缘相连。
在本实施案例中，防止所述雾化棉3底部被振烂的另一种优选方案为所述雾化棉3上与超声雾化片1相对应的位置为单层棉片，所述垫网层4内嵌于该单层棉片内。
如图9所示，在本实施案例中，防止所述雾化棉3底部被振烂的另一种优选方案为所述垫网层4夹设于雾化棉3与超声雾化片1之间。所述棉片的厚度为0.1～0.8mm，优选的厚度为0.1～0.4mm。所述垫网层4的厚度为0.05～0.3mm。
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。
