便携式冲牙器 技术领域
本发明涉及冲牙器技术领域，尤其涉及便携式冲牙器。
 背景技术
冲牙器是一种利用脉冲水流冲击的方式来清洁牙齿、牙缝的口腔清洁辅助工具。随着冲牙器技术的发展，出现了充电式的便携式冲牙器，其主机使用充电电池作为电源，使用的时候只需要充电，便可以使用一到两个星期左右，且其体积较小，机身不像台式冲牙器一样带有长长的电线，适合日常使用，也适合外出使用或者在没有电源的场所使用，使用起来更加方便，对于更多的用户来说，他们更喜欢便携式冲牙器。
现有的便携式冲牙器包括机身、水箱和喷嘴，喷嘴和水箱分别与机身相连，且喷嘴位于机身的一端。在实际使用中，申请人发现，现有的便携式冲牙器携带并不方便，因为喷嘴通常是细长结构，在用户携带时，需要给其安装一个保护罩，不然喷嘴容易出现损坏。而且，用户在携带时，现有的便携式冲牙器的长度等于保护罩的长度、机身长度及水箱高度三者之后，体积属实偏大。
因此，需要对现有的便携式冲牙器进行改进，以提高其便携性。

请结合图1至图4，所述座部7上设有限位件9，所述限位件9位于两个所述第一连接结构4之间，详细的，本实施例中，所述第一限位结构为沿所述座部7的周壁间隔设置的多个限位凸块，所述限位件9为沿所述座部7的周壁设置的限位凸环。具体的，两个所述第一连接结构4与所述限位凸环之间的间距相等，均等于所述水箱3中的第二连接结构5到所述水箱3开口端的端面的距离。换句话说，水箱3安装在机身1上后，水箱3的开口端是抵触所述限位凸环的，如此，可以避免水箱3出现意外晃动，利于提高便携式冲牙器的结构稳定性。
请结合图2、图5至图7，还包括分体设置的第一水管10及第二水管11，所述第一水管10与所述第二水管11配合导通，所述第一水管10设于所述机身1内，所述第二水管11设于所述水箱3内，这样，用户在携带便携式冲牙器时，第二水管11不会突兀的凸出于机身1，更方便用户携带。可选的，所述第二水管11与所述水箱3一体成型，容易理解的，所述第二水管11与所述水箱3一体成型的方式包括但不限于嵌件注塑成型和一体注塑成型。
但为方便清洁第二水管11，本实施例中，所述第二水管11与所述水箱3可拆卸连接，所述水箱3内设有用于安装所述第二水管11的安装件12，所述安装件12既可以是卡扣结构，也可以是套环结构，还可以是其他结构，本实施例中，所述安装件12为优弧卡扣。为防止用户在安装第二水管11时，将第二水管11抵触水箱3底部造成水流不畅，所述水箱3内还设有抵持所述第二水管11的端部的限位块13，所述限位块13与所述第二水管11的端面的部分区域抵触，达到架高第二水管11的效果，使得水箱3内的液体能够顺畅的流入第二水管11内。
需要说明的是，在其他实施例中，所述第一水管10与第二水管11还可以是一体的，此时，第二水管11为软管（如硅胶管），所述机身1的外壁上设有收容所述软管的限位腔，详细来说，当用户要携带便携式冲牙器时，先将喷嘴2从颈部8拆下并安装到座部7上，然后将水箱3拆下并安装到座部7上且令喷嘴2位于水箱3内，最后将第二水管11卡入限位腔内即可。
如图6所示，本实施例中，第一水管10的端部与第二水管11的端部并不是直接对接的，需要其他部件过渡，因此，第二水管11与机身1的连接处设置有硅胶制成的密封件14，便携式冲牙器在正常使用时，第二水管11顶压所述密封件14，容易理解的，所述密封件14的中部具有供液体通过的过孔。在其他实施例中，当第一水管10的端部与第二水管11的端部直接对接时，所述第一水管10与所述第二水管11的对接处设有密封环，此时，所述第一水管10及所述第二水管11分别抵持所述密封环。
如图2和图4所示，为方便用户操作，所述机身1上设有第一防呆结构15，所述水箱3上设有与所述第一防呆结构15相配合的第二防呆结构。本实施例中，所述第一防呆结构15为防呆凸起。
实施例二
请参照图8，本发明的实施例二是在实施例一的基础上做出的进一步改进，与实施例一的不同之处仅在于：便携式冲牙器还包括封盖16。
具体的，为避免用户在携带便携式冲牙器时，异物进入机身1内部，便携式冲牙器还包括与所述机身1可拆卸连接的封盖16，当水箱3在保护喷嘴的时候，封盖16与机身1安装以封闭机身1与水箱3的连通区域，为简化设计、节约成本，所述封盖16上设有所述第二连接结构，也就是说，用户在携带便携式冲牙器时，机身1上的一个所述第一连接结构4与水箱3上的第二连接结构配合，机身1上的另一个所述第一连接结构4与封盖16上的第二连接结构相配合。
可选的，所述水箱3上设有用于安装所述封盖16的第一连接结构4，如此，不管是在用户正常使用便携式冲牙器时，还是在用户携带便携式冲牙器时，封盖16均不易遗失，利于增强用户体验。
综上所述，本发明提供的便携式冲牙器，结构简单、新颖，制造容易，生产成本低；清洁方便、工作稳定，用户体验佳；收纳占用空间小，携带方便。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
