Description

一种洁牙器的水雾生成结构 技术领域
本发明涉及洗牙装置技术领域，特别指一种洁牙器的水雾生成结构。
 背景技术
市场上现有的使用水雾喷射来清洁牙齿的洁牙器，这种洁牙器原理是利用液体与气流接触时，高速气流作用于液体迫使其从喷嘴喷出形成水雾；高速气流来源于诸如盛装筒的压缩气体来提供气流所需的能量；这种盛装筒气源有安全上的局限性，需要频繁替换，使用不便也不环保。
中国专利CN102271661B公开了用于在洁牙用具中生成液滴的非加压系统，包括洁牙用具，其具有主体部分和喷嘴部分，液体储存器以及系统，系统利用充分的力朝向喷嘴近端驱动柱塞或活塞元件，使得由柱塞或活塞元件所作用的空气以高速率被驱入或被释放到喷嘴部分内，从而足以在移动空气与液体形成接触时产生液滴喷射。液体储存器中的液体通过泵或抽吸移动到孔口附近，驱动齿轮具有开放空间，使得当开放空间临近该柱塞或活塞上的齿轮齿条时，断开啮合连接释放柱塞，在压缩弹簧作用下驱动柱塞朝孔口高速释放，从而驱动腔室内的空气通过该孔口。这种生成液滴的非加压系统替代了盛装筒气源结构，从而避免替换和安全局限，但是需要输液和输气两套机构同步运作，且雾化生成效果受到喷嘴规格限制，无法独立使用喷液或喷气模式，且输出量不可调节。
因此，现有技术还有待于改进和发展。
