Description

一种喷雾机构 技术领域
本实用新型涉及喷雾设备领域，具体为一种喷雾机构。
背景技术
现有的喷雾机构，特别是用于扩香设备的喷雾机构大多通过垂直或以60-90°夹角布置的出液孔和出气孔使液体通过气体产生的负压而形成小液滴喷出。
对于粘度较低的液体，一般的喷雾机构都可以很好的将其形成雾状，但是对于粘度稍大的液体，通常有部分液滴的粒径会比较大，因此形成喷油现象。
实用新型内容
本实用新型的目的在于提供一种喷雾效果好、使用寿命长的喷雾机构。
为实现上述目的，本实用新型提供如下技术方案：一种喷雾机构，包括瓶体、设置在瓶体上的喷雾头和设置在喷雾头上方的导流盖，所述的导流盖上设喷雾出口，所述的导流盖上设有与大气相通的空气回流孔，所述的喷雾头和导流盖之间或导流盖内设有用于截留喷雾头中喷出的大于预设粒径的液滴的截留机构。
在上述的喷雾机构中，所述的截留机构为与喷雾头喷雾方向呈夹角布置的设置在导流盖上喷雾通道，所述的喷雾出口设置在喷雾通道的自由端。
在上述的喷雾机构中，所述的喷雾头包括与瓶体连接的盖体、设置在盖体上的一体成型的喷头；所述的盖体上设置有与瓶体相通的进液通道和与外设气源相通的进气通道，所述的喷头上设有与进液通道相通的出液孔和与进气通道相通的出气孔，所述的出液孔和出气孔之间形成夹角以使出液孔处形成足以使瓶体内的液体从出液孔排出的负压。
在上述的喷雾机构中，所述的出气孔和出液孔之间的夹角为90°。
在上述的喷雾机构中，所述的喷头包括基座、设置在基座上的出液座和出气座，所述的出液孔设置在出液座内，所述的出气孔设置在出气座内，所述的出气孔竖直向上布置； 所述的喷雾通道倾斜布置；所述的喷雾通道的底部位于出气孔的正上方。
在上述的喷雾机构中，所述的出气孔的部分被出液座遮蔽。
在上述的喷雾机构中，所述的出液座上方设有一个位于出液孔上方的导流斜面。
在上述的喷雾机构中，所述的中空导流柱倾斜的方向和导流斜面倾斜的方向相同。
在上述的喷雾机构中，所述的盖体和瓶体之间设有用于使盖体内积存的液体回流至瓶体内的回流孔。
在上述的喷雾机构中，所述的导流盖内部设有用于改变空气回流孔的空气流动方向的内环。
与现有技术相比，本实用新型的有益效果是：
本实用新型采用空气回流孔和截留机构的设置，可以达到两个效果，第一个效果是，空气回流孔会提高导流盖内的气体流动速度，在同样的功率的情况下，喷雾效果更好，可以有效延长机器使用寿命；第二个效果是，截留机构可以在喷雾效果提高的同时，降低雾中的大颗粒粒径的数量，是喷雾更为均匀。
本实用新型采用与喷雾头喷雾方向呈夹角布置的设置在导流盖上喷雾通道是一种独特的截留机构，其结构简单，无需额外的驱动即可实现大颗粒的粒径的截留。但是在本实用新型中，并不限定截留机构为以上结构，常用的，倾斜的导流板或者导流自驱动扇叶也是可行的。
本实用新型采用独特结构设计的一体成型的喷头，这样设计的好处在于，避免了在组装过程中产生的误差。安装工人只需要将一体成型的喷头安装到盖体上对应的进液通道和进气通道即可。
进一步地改进，出气孔竖直向上布置，且出气孔和出液孔之间的夹角为90°，这样可以较好的将液体向上喷出。并且进一步优选，与倾斜的中空导流柱配合，这样从喷雾头喷出的液体的方向和中空导流柱的导流方向有一定的夹角，使大颗粒液滴被拦截下，喷雾出来的液滴粒径更小，能够产生更为优益的雾化效果。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
实施例1
请参阅图1-3一种喷雾机构，包括瓶体1、设置在瓶体1上的喷雾头2和设置在喷雾头2上方的导流盖3，所述的导流盖3上设喷雾出口31，所述的导流盖3上设有与大气相通的空气回流孔32，所述的喷雾头2和导流盖3之间或导流盖3内设有用于截留喷雾头2中喷出的大于预设粒径的液滴的截留机构。
其工作原理在于：喷雾头2喷雾并形成负压，使外界的空气从空气回流孔32进入到导流盖3内进一步提高喷雾效果。在喷雾过程中，通过截留机构提高雾中液滴均匀性。
所述的截留机构为与喷雾头2喷雾方向呈夹角布置的设置在导流盖3上喷雾通道33，所述的喷雾出口31设置在喷雾通道33的自由端。本实施例采用与喷雾头2喷雾方向呈夹角布置的设置在导流盖3上喷雾通道33是一种独特的截留机构，其结构简单，无需额外的驱动即可实现大颗粒的粒径的截留。但是在本实用新型中，并不限定截留机构为以上结构，常用的，倾斜的导流板或者导流自驱动扇叶也是可行的。
在本实施例中，所述的喷雾头2包括与瓶体1连接的盖体21、设置在盖体21上的一体成型的喷头22；所述的盖体21上设置有与瓶体1相通的进液通道23和与外设气源相通 的进气通道24，所述的喷头22上设有与进液通道23相通的出液孔25和与进气通道24相通的出气孔26，所述的出液孔25和出气孔26之间形成夹角以使出液孔25处形成足以使瓶体1内的液体从出液孔25排出的负压，所述的出气孔26和出液孔25之间的夹角为90°。所述的喷头22包括基座27、设置在基座27上的出液座28和出气座29，所述的出液孔25设置在出液座28内，所述的出气孔26设置在出气座29内，所述的出气孔26竖直向上布置；所述的喷雾通道33倾斜布置；所述的喷雾通道33的底部位于出气孔26的正上方。
作为上述结构的进一步细化，所述的出气孔26和出液孔25之间的夹角为90°的设置优点在于利于在出液孔25的位置形成负压，提高液体排出效果，提高雾化效能。
优选地，所述的出气孔26的部分被出液座28遮蔽，所述的出液座28上方设有一个位于出液孔25上方的导流斜面20。这样设置的目的在于，使出气孔26的出气压力更大，并且出气流量更多集中在导流斜面20的位置，提高雾化效果。
所述的中空导流柱倾斜的方向和导流斜面20倾斜的方向相同。相同的设计的目的是提高导流效果，避免过多的小颗粒液滴被截留机构截留。
在本实施例中，所述的盖体21和瓶体1之间设有用于使盖体21内积存的液体回流至瓶体1内的回流孔，所述的导流盖3内部设有用于改变空气回流孔32的空气流动方向的内环34。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本实用新型的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
