Abstract

一种牙科喷嘴装置。一种空气‑水注射器装置，其具有围绕分离的水通道和空气通道的缸，该缸设计成允许空气通道被该装置的出口处的至少2个导向轮叶转向，以根据用户的需要引导水流。本发明公开了至少1个空气通道，该空气通道围绕装置的缸的整个内周。导向轮叶的倾斜度可以设计成所需的角度，但通常导向轮叶的倾斜度在46°和28°的范围内。该装置可以根据需要设计成具有柔性区段和手指抓握器。

Description

牙科喷嘴装置
背景技术
众所周知，市场上现有的空气-水注射器可使牙医在每次手术中为每个患者冲洗并干燥口腔。这些已知的装置以不同的方式配置和操作。所公开和要求保护的装置提供了一种新颖、更有效和更容易操作的一次性空气-水注射器设计。
发明内容
公开了包括双管设计的牙科喷嘴装置或空气-水注射器设计。水通道在装置的进口处被空气通道围绕。然后，通过装置的末端的导向轮叶将单个空气通道分成3个出口。导向轮叶的喷射角度和形状允许螺旋和圆锥形的喷射角度以及微小的雾气。柔性带区域允许牙医在不影响水和空气流动的情况下调节装置的角度。
附图说明
为了更好地理解本文描述的实施例并更清楚地示出它们如何实现，现在仅以举例的方式参考以下附图。
图1示出了用于适配器模型的空气-水注射器装置的立体图。
图2描绘了空气-水注射器装置的细长模型的立体图。
图3示出了空气-水注射器装置的侧视图。
图4示出了用于空气-水注射器装置的出口的图3的截面C-C。
图5示出了图3的截面A-A，示出了内部缸体。
图6示出了用于空气-水注射器装置的进口的图3的截面B-B。
图7示出了用于空气-水注射器装置的出口的图3的截面C-C的出口的放大图。
将理解的是，为了图示的简单和清楚起见，图中所示的元件未必按比例绘制。例如，为了清楚起见，一些元件的尺寸可能相对于其他元件被放大。

2.水通道
3.空气通道
4.出水口
5.导向轮叶
6.进水口

具体实施方式
如图1所示，用于适配器模型的空气-水注射器装置包括带有手指抓握器(7)的从进口端(11)延伸到出口/末端(12)的缸体(1)、以及在缸体(1)上的柔性区段(8)。图2描绘了空气-水注射器装置的细长模型的立体图。适配器和细长版本的工作原理相同。唯一的区别是它们的设计适合不同型号的手持件。适配器类型需要在手持件和空气注射器之间建立连接器。使用的方向是为了用户***和锁定手柄。
图3示出了空气-水注射器装置的侧视图。图4、5和6所示的空气-水注射器装置描绘了内部构造。图4示出了用于空气-水注射器装置的出口的图3的截面C-C，其包括出水口(4)、导向轮叶(5)和出气口(10)。图5示出了图3的截面A-A，其示出了具有水通道(2)、空气通道(3)、出水口(4)和出气口(10)的内部缸体。
图6示出了用于空气-水注射器装置的进口的图3的截面B-B，其描绘了进水口(6)和进气口(9)。水通道(2)通过一个出水口(4)到达装置的末端。空气流通过导向轮叶(5)在装置的末端(12)分成3个出口(10)。如图所示，空气通道(3)从进气口(9)开始，围绕从缸的进口端到出气口的轮叶处的导向轮叶的该通道的整个内周。在出气口(10)处，空气通道(3)中的空气被导向轮叶(5)转向，以在装置的末端(12)处的三个出口(10)中排出。该装置不仅限于需要3个出气口和1个内水管(2)。该装置可具有用于空气和用于水的多个通道/管。
图7示出了用于空气-水注射器装置的出口的图3的截面C-C的出口的放大图。它显示了46°和28°的喷射角，以及精确控制空气和水雾的装置的导向轮叶(5)。在设计实验期间，应选择导向轮叶(5)的这些角度和倾斜度，以获得最佳喷射效果。该装置不限于具有这些角度；该装置还可以采用46°和28°范围内的任何角度或导向轮叶倾角。
可以使用注塑成型将该装置制成一件，因此无需组装。该装置还可以具有需要组装的多件式设计。在一个实施例中，所使用的材料是白色聚丙烯(PP SM498)，并且质地是光滑的。但是可以根据特定的要求和偏好来选择所使用的材料、颜色和表面处理。
所公开的多通道注射器主要用于利用空气和水的牙科应用。但是，多通道设计可适用于其他应用以及其他类型的气体和液体。
图1和2还显示了柔性区段(8)。一种实现柔性弯曲的方法是在注模之后和材料冷却之前增加一个额外的步骤。该装置弯曲到可调角度。柔性来自于聚丙烯的物理性能及其在注塑后但完全冷却之前的温度。
本发明公开了一种空气-水注射器，其包括：具有进口端和出口端的缸；从进口端到出口端的至少1条水通道；从进口端到出口端的至少1条空气通道；在空气通道的位于缸的出口端处的一端的至少2个导向轮叶。
在一个实施例中，空气-水注射器的空气通道围绕从缸的进口端到缸的出口端处的至少2个导向轮叶的通道的整个内周。
公开的用于空气-水注射器的实施例可以包括至少1个空气通道，该空气通道由导向轮叶转向以在三个出口中离开。
已经描述了用于说明作为本专利主题的各种概念，结构和技术的优选实施例，对于本领域普通技术人员而言，现在可以显而易见的是，可以使用结合了这些概念、结构和技术的其他实施例。因此，提出专利的范围不应限于所描述的实施例，而应仅由所附权利要求的精神和范围来限定。
