Description

用于在洁牙用具中生成液滴的非加压系统
技术领域
本发明大体而言涉及液滴洁牙器,且更具体而言涉及一种用于生成液滴喷射来洁牙的非加压系统。
背景技术
使用液滴喷射来清洁牙齿的齿区(包括邻间区域)的洁牙器是已知的。在许多这样的用具中,当使液体与气流接触时,高速气流用于形成液滴,这诸如通过泵或其它布置来进行。
通常,高速气流使用诸如来自盛装筒源的压缩气体,以提供气流所需的能量。压缩气体用具通常有效地产生液滴用于清洁。但是,压缩气体确具有已知的局限性,包括安全性限制且某些使用者反对品尝所形成的液滴。用尽的气筒也必须要安全地且以适宜环境的方式来处置,这会不方便。
因此,期望具有一种液滴牙齿用具,其能利用非加压气体源来产生液滴进行清洁,特别地无需可消耗的压缩气体筒。
发明内容
因此,本发明是一种用于洁牙的流体滴用具,其包括:洁牙用具,其具有主体部分和喷嘴部分,喷嘴部分用于从其远端喷射出液滴;液体储存器,其中在操作中,液体从储存器移动到靠近其开口近端的喷嘴的区域内;以及系统,其用于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内,从而足以在移动空气与液体形成接触时生成液滴喷射。
附图说明
图1是非加压液滴用具的第一实施例的示意图。
图2是另一实施例的示意图。
图3是另一实施例的示意图。
具体实施方式
图1示出用具10,其使用机械弹簧驱动系统来生成液滴喷射以用于洁牙。该用具包括电机和齿轮系布置12,齿轮系布置12具有驱动齿轮13,该电机由电池14加电。控制单元15包含于电池与电机之间以用于控制该用具的操作。按钮或类似元件17用于致动该用具。齿轮系驱动柱塞/活塞构件16,其中驱动齿轮13接合位于柱塞/活塞16上的齿轮齿条18。随着驱动齿轮12旋转,柱塞/活塞16克服压缩弹簧24的作用而移动到该用具10的后部。同时,空气被抽到该用具中的腔室26内,腔室26可为该用具的内部,或者该用具内部内的单独体积。
该用具包括细长喷嘴30,细长喷嘴30从该用具向外延伸且通常在其远端具有弯曲部32,液滴喷射通过该弯曲部32被导向至牙齿的齿区以进行清洁动作。弯曲部32辅助使用者将喷嘴30方便地定位于口中。在喷嘴的近端,邻近该用具的主体27处是孔口36。孔口36的大小可不同,通常在0.5mm与10mm之间。如上文所示,当柱塞/活塞16由于电机和齿轮系12的作用而移动到后部时,空气通过孔口36或替代地通过与腔室26连通的用具主体27中的单向止回阀而抽到腔室26内。
水或其它液体的储存器28也存在于该用具中。储存器38中的液体在该喷嘴内移动到孔口36的附近,这通常由泵或通过无源抽吸或其它手段来进行。
所示实施例中的驱动齿轮13在其外围在选定位置处具有开放空间(齿缺失),使得当开放空间邻近该柱塞/活塞上的齿轮齿条18时,因为并无啮合的齿轮阻止柱塞,因此由于压缩弹簧24朝向其平衡(非压缩)位置移动的作用而使柱塞朝向孔口36以高速释放。此作用足够以高速驱动腔室26中的空气通过该孔口36。当快速移动的空气与邻近孔口36的液体形成接触时,产生液滴喷射。
液滴可具有各种大小且液滴速度可以从例如每秒10米的相对低速至每秒200米或甚至更大的高速进行变化。但通常,对于5微米至0.5mm大小范围的液滴,50m/秒液滴速度将提供有效的牙齿清洁。
图2示出通常被称作音圈驱动的另一非加压气体驱动实施例。该用具总体上以50示出。其包括主体部分52和喷嘴部分54,喷嘴部分54从主体部分向前延伸。主体部分52包括致动元件72。定位于主体部分52内的是水储存器56和电池与电路(电子器件)部分58。电池和电路部分58连接到音圈组件60,向其提供加电信号。电池和电路部分58包括电容器62。音圈60环绕磁体64。连接到磁体64且定位于磁体64与喷嘴部分54的近端之间的是活塞66。在喷嘴部分54的近端68,邻近主体部分52的是喷嘴孔口70。孔口70通常具有0.5mm至10mm的直径。
在一种布置中,在操作中,使用者操作按钮72。此对音圈60加电,这向后拉动磁体64,继而朝向该用具的后部拉动活塞66。当活塞向后移动时,空气通过孔口70或通过主体部分中的单向阀移动到主体部分52的内部。空气可移动到该用具内部或者到该用具内的腔室内。电容器62也开始充电。当充电到达特定预选水平时,电容器向音圈内放电,这向前驱动该磁体,以朝向该孔口推动活塞。
在另一布置中,在操作按钮72之前,音圈将磁体和活塞维持在后部位置。当操作按钮72时,电容器开始充电,直到其到达选定充电水平,在此点,电容器向音圈内放电,其向前驱动该磁体和活塞。
由每个布置中的活塞产生的充分的力来迫使空气以高速通过孔口70。被迫通过该孔口的空气接触液体,液体由泵或类似物通过管线73被导向至喷嘴下端。由快速移动的空气与液体的相互作用来形成液滴。所形成的液滴大小不同。在此布置中,液滴将(例如)在5微米至0.5mm之间。气流还将有助于移动液滴通过喷嘴且朝向牙齿喷出以进行清洁。
在另一实施例中,参看图3,用具80在主体部分81中包括泵82,泵82作用于缸86中的活塞84上,以在容积阀88中压缩空气到规定压力。操作由按钮87启动,电力由电池91提供。当到达规定压力时,释放阀,且压缩空气被迫通过孔口90以接触喷嘴部分92下部中的液体。由快速移动的气体与液体的相互作用来生成液滴且液滴移动通过喷嘴92的出口94。
因此,已经描述了若干实施例,其产生通过喷嘴的液滴喷射以用于洁牙,无需使用加压气体系统而使用大气。
尽管出于说明目的公开了本发明的优选实施例,应了解在不偏离在后权利要求书所限定的本发明的精神的情况下,各种变化、修改和替代可合并于实施例中。
