Description

雾化扇喷雾口组件 技术领域
本发明涉及电器领域，具体而言，涉及一种雾化扇喷雾口组件。
背景技术
雾化扇是一种户外用或者在开放开阔式的室内使用的制冷系统，其通常是通过离心力或者高压方式产生雾滴，再通过强力风扇吹出的气流来推动雾滴流动，提高液体表面风速，加快空气分子的扩散，从而带来降温的效果。雾化扇广泛应用于酒店、会所、车间、户外等多种场合。但是，现有技术中的雾化扇喷雾口组件采用的是半开口方式，出雾不集中、出雾效果差，易发生积水和漏水等问题。
发明内容
本发明实施例中提供一种雾化扇喷雾口组件，以解决现有技术中出雾不集中、喷射距离近、易积水漏水的问题。
为实现上述目的，本发明实施例提供一种雾化扇喷雾口组件，包括壳体和挡筋，挡筋沿壳体的喷雾口的宽度方向设置并遮挡一部分喷雾口。
优选地，挡筋的截面呈U形。
优选地，壳体包括相互连接的第一壳体和第二壳体，第一壳体的本体的表面上突出地形成有两个并排设置的突筋，两个突筋之间形成连接槽。
优选地，两个突筋呈U形，挡筋位于U形的开口端。
优选地，挡筋突出地设置在第一壳体的朝向第二壳体一侧的表面上。
优选地，第二壳体包括本体和由本体的一侧向外突出的连接筋，连接筋与第一壳体的朝向第二壳体一侧的表面连接，第一壳体、连接 筋及第二壳体的本体之间形成喷雾口。
优选地，第一壳体包括本体和连接槽，连接筋的远离第二壳体的本体的一侧位于连接槽内。
优选地，挡筋的两端与U形的开口之间间隙配合。
优选地，连接筋与第一壳体的朝向第二壳体一侧通过超声波焊接的方式连接。
优选地，第一壳体还包括由第一壳体的本体的表面向第二壳体一侧突出的支撑筋。

具体实施方式
下面结合附图和具体实施例对本发明作进一步详细描述，但不作 为对本发明的限定。
请参考图1至图5，本发明提供了一种雾化扇喷雾口组件，包括壳体和挡筋1，挡筋1沿壳体的喷雾口2的宽度方向由喷雾口2的一端延伸至另一端，并遮挡一部分喷雾口2。在一个实施例中，挡筋1的宽度几乎大致上相当于喷雾口2的宽度。
由于本发明在喷雾口2处设置有挡筋1，使得气流在喷雾口2汇集成一股气流13，确保了气流的唯一性，可使出雾集中，不会出现多股气流而引起乱流，从而正前方不会出现因乱流引起的积水现象，确保了不会积水漏水。反之，如若无挡筋1，则气流14也会在喷雾口处出现，即有两股气流13和14从喷雾口2喷出，两股气流13和14会相互交叉产生乱流，以致使喷雾口2的前壳正面积水，水滴约积约大，最终出现漏水现象。可见，本发明中的挡筋1构成了一种内部挡水结构，该结构能够使出雾集中，并使出雾喷射得更远。
在一个优选实施例中，挡筋1的截面呈U形，其两端高、中间低，这样，中间部分可以起到使出雾集中的目的，而两端高的部分则构成位于喷雾口2的两侧的两片侧筋，其可防止气流往两边窜，避免两侧积水漏水。优选地，两端高的部分的高度在0-15mm之间，而中间部分的高度在1-10mm之间。
在本发明的优选实施例中，壳体由两个基本上平行设置的第一壳体3和第二壳体4相互连接而成，其中，挡筋1突出地设置在第一壳体3的表面上，且朝向第二壳体4。例如，挡筋1可与第一壳体3一体成型。
更优选地，第二壳体4包括本体5和连接筋6，其中，连接筋6由本体5的一侧向外突出(例如，本体5可以与连接筋6一体成型)，连接筋6与第一壳体3的朝向第二壳体4一侧的表面连接，这样，连接筋6位于第一壳体3与第二壳体4之间的间隙处，从而在第一壳体3、连接筋6及第二壳体4的本体5之间形成上述的喷雾口2。
请参考图1和图4，本发明中的第一壳体3包括本体7和连接槽8，其中，连接筋6的远离第二壳体4的本体5的一侧位于连接槽8内，从而实现更好地连接与密封。在一个优选实施例中，第一壳体3的本体7的表面上突出地形成有两个并排设置的突筋9，两个突筋9之间形 成连接槽8。更优选地，两个突筋9呈U形，挡筋1位于U形的开口端。优选地，挡筋1的两端与U形的开口之间间隙配合，例如，0～1mm。
现有技术中通常采用增加密封圈或涂胶水的装配方式来进行密封，但其密封效果差，且生产装配效率低下。为此，连接筋6与第一壳体3的朝向第二壳体4一侧通过超声波焊接的方式连接。具体地说，连接筋6可以通过超声波焊接的方式与连接槽8焊接起来，最终起到密封雾和水的作用，同时提高了装配效率。
优选地，第一壳体3还包括由第一壳体3的本体7的表面向第二壳体4一侧突出的支撑筋。当第一壳体3与第二壳体4连接起来时，支撑筋的一侧抵住第二壳体4的表面，起到支撑作用。例如，该支撑筋包括U形的第一筋10，第一筋10围绕连接槽8的外部设置。此外，该支撑筋还包括第二筋11，第一筋10的自由端处分别设置有一个第二筋11，第二筋11沿第一筋10的径向设置。第二筋11与第一筋10的端部连接并形成一个弯折结构，从而提高了支撑的强度。
如图1至图3所示，本发明中的第二壳体4的本体5的直径大于第一壳体3的本体7的直径，第一壳体3与第二壳体4同心地设置，且连接筋6的两个自由端均延伸至第二壳体4的边缘处，从而在第一壳体3和第二壳体4之间的环状间隙处形成一个限制气流方向的限制结构，以限定喷雾口的宽度。
优选地，第二壳体4上形成有进口12，连接筋6围绕在进口12的外侧。气流由进口12处流入壳体，然后进入第一壳体3、第二壳体4及连接筋6之间围成的腔体内，然后由喷雾口2喷出。
优选地，喷雾口的宽度为30-90毫米(更优选地为60毫米)，因此本发明的喷雾口比现有技术中的宽度要窄，故可保证出雾集中且喷射较远。
当然，以上是本发明的优选实施方式。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明基本原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
