Abstract

本发明涉及可反转的空气辅助无空气喷头。装置(10)使用标准的可反转无空气喷头(12)。空气帽(18)设置有四个空气通道(20)，该空气通道与壳体(30)的中心线径向向内成45°的角度。通道(20)与垂直于组件(10)的纵向轴线(24)的平面成12°的角度。由这些通道提供的四个喷口(20)由位于壳体(30)表面中的四个沟槽(28)(也具有12°的倾斜角)进行导向，以将气流引导到硬质合金件(14)中的椭圆形喷孔(14a)的中心。两对相对的空气喷口(22)也位于空气帽(18)内，并垂直指向涂料或其他喷雾材料的扇形物(26)，并且这些喷口(22)相对于垂直于组件(10)的纵向轴线(24)的平面成大约20.5°的角度。每一对相互指向且相对于纵向轴线(24)横向间隔开，以有助于将尾部从图案移除。

Description

可反转的空气辅助无空气喷头
分案申请说明
本申请是申请日是2008年4月3日、申请号是200880011545.5且发明名称是“可反转的空气辅助无空气喷头”的中国发明专利申请的分案申请。
技术领域
本申请要求2007年4月10日提交的美国申请序号为60/911,011的利益。本发明涉及可反转的空气辅助无空气喷头。
背景技术
可反转的无空气喷嘴已为人们所熟知并广受欢迎。空气辅助的无空气喷射枪也广受欢迎，但由于沿需要的空气通道到喷头前端存在困难，因此该喷射枪一般不能反转喷头用来清洁。
发明内容
本发明的装置使用标准的可反转喷头，如Graco(格雷索)的FFT210。空气帽设置有四个径向向内的空气通道，且在优选实施例中，空气帽定位成与壳体的中心线成45°角度。所述通道与所述组件的纵向轴线的垂直方向成12°的角度。由这些通道提供的四个喷口由位于壳体的表面中的四个沟槽(也具有12°的倾斜角)进行导向，以将气流引导到硬质合金件中的椭圆形喷孔的中心。
两对相对的空气喷口也设置在空气帽中，并垂直指向涂料或其他喷雾材料的扇形物，并且这些喷口相对于垂直于所述组件的纵向轴线的平面成大约20.5°的角度。每一对相互指向并相对于所述纵向轴线横向间隔开，以有助于将尾部从图案移除。
通过以下结合附图的描述，本发明的上述及其他目的和优点将更明显，其中在几个视图中相同的附图标记表示相同或相似的部件。
附图说明
图1是本发明的喷头组件的正面透视图。
图2是本发明的空气帽的正面平面图。
图3是沿图2中的线3-3截取的剖面图。
图4是沿图2中的线4-4截取的剖面图。
图5是本发明的壳体的正面透视图。
图6是本发明的壳体的正面平面图。
图7是沿图6的线7-7截取的剖面图。
图8是本发明的喷头组件的替代实施例的正面透视图。
具体实施方式
在图1中空气辅助的无空气喷头组件被总体标记为10，并且该喷头组件包括具有硬质合金件14的常规可反转喷头12，其中猫眼形喷孔14a定位成使得其主要尺寸垂直于筒体16。图2-4详细示出了空气帽18，该空气帽18分别设置有第一组喷口20和第二组喷口22。倾斜喷口20径向向内指向组件10的纵向轴线24，且相对于垂直于组件10的纵向轴线24的平面稍向前成大约12°的角度。
所述第二组喷口22垂直指向扇形物26并从纵向轴线24横向间隔开。喷口24与垂直于组件10的纵向轴线24的平面成大约20.5°的角度。
倾斜喷口20被设置成用来沿位于壳体30前部的沟槽斜坡28引导气流，所述沟槽斜坡28同样相对于垂直于组件10的纵向轴线24的平面成大约12°的角度，从而将所述流引导到椭圆形或猫眼形的喷孔14a的中心。
图8示出了替代实施例，其中喷头组件30包括具有硬质合金件34的可反转喷头32，其中猫眼形喷孔34a设置成使得其主要尺寸平行于(而非现有技术中常见的垂直于)筒体36。一对喷口38在喷孔34a的主要尺寸的相对侧指向并垂直于喷雾扇形物40。
在不偏离由以下权利要求所限定的本发明的精神和范围的情况下，可以预期对所述喷头组件进行各种改变和变型。
