Description

一种具有扩容水箱的口腔护理设备 技术领域
本发明涉及一种个人用品，尤其涉及口腔护理设备。
背景技术
刷牙是最普遍的一种牙齿保健行为，然而，大多数的牙刷并不能让牙膏深入咬合面的缝隙、沟槽及裂缝中，因此需要冲牙器作为牙刷的辅助用具对牙齿进行清洁。冲牙器一般包括冲牙器主体以及与冲牙器主体可拆卸连接的喷嘴。冲牙器主体包括水泵，水泵能够抽吸清洗液，并将清洗液以一定的压力通过喷嘴喷出，从而对牙缝及牙龈沟等牙刷不易清洁的地方进行清洁。而且，冲牙器还能使清洗液进入咬合面的缝隙以中和里面的酸性物质，并使原本已经脱钙的牙釉质恢复钙含量。然而，目前的冲牙器，为了保证体积小巧，水箱容积都比较小，需要经常加水，使用不方便。
发明内容
本发明所要解决的主要技术问题是提供一种口腔护理设备，水箱的容积可变。
为了解决上述的技术问题，一种具有扩容水箱的口腔护理设备，包括：主机、出水嘴，水箱本体、柔性储水囊；
所述主机和水箱本体活动连接，所述水箱本体通过换向件连接所述柔性储水囊；所述换向件用于将主机相对于水箱本体的移动转换为柔性储水囊的展开或收缩；所述水箱本体设有与柔性储水囊连通的过 水口。
在一较佳实施例中：所述主机与水箱本体沿着水箱本体的高度方向活动连接，以使得主机在第一位置和第二位置之间移动；
所述主机位于第一位置时，所述柔性储水囊处于收缩状态，所述主机位于第二位置时，所述柔性储水囊处于展开状态。
在一较佳实施例中：所述水箱本体和主机设置有定位件和定位配合件，用于将主机定位在第一位置或第二位置。
在一较佳实施例中：所述定位件和定位配合件分为第一定位件和第一定位配合件，以及第二定位件和第二定位配合件；

在一较佳实施例中：所述主机内设置有电机和活塞泵组件；所述活塞泵组件的吸水端与所述水箱本体连通，出水端与所述出水嘴连通；所述电机用于驱动活塞泵组件中的活塞做往复运动。
在一较佳实施例中：所述柔性储水囊为两个，分别置于所述水箱本体的两侧。
在一较佳实施例中：所述换向件包括扭簧和连杆机构；所述扭簧的第二端为固定端，第一端与连杆机构连接；
所述主机处于第一位置时，所述主机挤压连杆机构以使得所述扭簧积累弹性复位力。
在一较佳实施例中：所述连杆机构包括置于柔性储水囊中的第一连杆和第二连杆；所述第一连杆的第一端和第二连杆的第二端活动连接，第一连杆的第二端与所述扭簧的第一端活动连接；所述第二连杆的第一端与所述水箱本体铰接。

相较于现有技术，本发明的技术方案具备以下有益效果：
1.本发明提供了一种具有扩容水箱的口腔护理设备，将传统的伸缩冲牙器增加储水囊，在原有的容积上增加更大的储水空间。
2.本发明提供了一种具有扩容水箱的口腔护理设备，纵向扩容的口腔护理设备重心偏高，整体不稳的缺陷，而本款口腔护理设备为横向扩容，重心低，整体平稳。
3.本发明提供了一种具有扩容水箱的口腔护理设备，当进水口在主机顶部或水箱底部时，比水箱采用纵向扩容的产品更容易装水，因为大部分家庭水龙头与洗脸盆距离较近。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述；显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例，基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“内”、“外”、“顶/底端”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅用于描述 目的，而不能理解为指示或暗示相对重要性。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置有”、“套设/接”、“连接”等，应做广义理解，例如“连接”，可以是壁挂连接，也可以是可拆卸连接，或一体地连接，可以是机械连接，也可以是电连接，可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通，对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
参考图1-图10，本发明提供了一种具有扩容水箱的口腔护理设备，包括：主机1、出水嘴2，水箱本体3、柔性储水囊4；
所述主机1和水箱本体3活动连接，所述水箱本体3通过换向件5连接所述柔性储水囊4；所述换向件5用于将主机1相对于水箱本体3的移动转换为柔性储水囊4的展开或收缩；所述水箱本体3设有与柔性储水囊4连通的过水口31。
上述的口腔护理设备，用户通过主机1和水箱本体3之间的相对运动，就能够使得柔性储水囊4展开或者收缩，从而改变柔性储水囊4的容积，进而改变整个口腔护理设备的容积。实现了容积可变的目的，这样用户就无需在使用口腔护理设备时频繁加水，方便快捷。
本实施例中，所述主机1与水箱本体3沿着水箱本体3的高度方向活动连接，以使得主机1在第一位置和第二位置之间移动；所述主机1位于第一位置时，所述柔性储水囊4处于收缩状态，所述主机1位于第二位置时，所述柔性储水囊4处于展开状态。沿着高度方向的移动方式比较符合用户的使用习惯，并且主机1这样活动不会额外增加口腔护理设 备的整体宽度，用户使用感受比较好。
并且，所述柔性储水囊4为两个，分别置于所述水箱本体3的两侧。这样柔性储水囊4展开时只增加口腔护理装置的宽度，重心低，整体平稳。并且这种横向扩容的方式也比较容易装水，而纵向扩容的方式会使得口腔护理设备的高度增加太多，无法适配龙头与洗脸盆之间的距离。
本实施例中，为了实现柔性储水囊4的展开和收缩，所述换向件5包括扭簧51和连杆机构52；所述扭簧51的第二端为固定端，第一端与连杆机构52连接；所述主机1处于第一位置时，所述主机1挤压连杆机构52以使得所述扭簧51积累弹性复位力。
这样主机1对扭簧51施加的是沿着主机1运动方向上的作用力，而扭簧51复位时产生的是转动力，该转动力就可以驱动连杆机构52运动，使得连杆机构52向着靠近或者远离水箱主体的方向运动，连杆机构52朝着远离水箱主体的方向运动时，柔性储水囊4就会被连杆机构52撑开。而连杆机构52朝着靠近水箱主体的方向运动时，储水囊又会在自身弹性复位力的作用下收缩复位。
具体来说，所述连杆机构52包括置于柔性储水囊4中的第一连杆521和第二连杆522；所述第一连杆521的第一端和第二连杆522的第二端活动连接，第一连杆521的第二端与所述扭簧51的第一端活动连接；所述第二连杆522的第一端与所述水箱本体3铰接。本实施例中，所述第一连杆521的第一端设有滑块523，相应的第二连杆522的第二端设有滑槽254，所述滑块253限定在滑槽254内活动连接。
所述第一连杆521为L形，其第二端为短边沿着长度方向设置有让位槽，所述扭簧51的第一端置于所述让位槽内；所述第一连杆521长边和短边的连接处与所述水箱本体3铰接。让位槽的作用是让扭簧51在释放复位力转动时，扭簧51的第一端可以在让位槽内移动，这样整个装置就不会卡死。
本实施例中，所述主机1位于第一位置时，所述主机1沿着高度方向的下端面与所述第一连杆521的短边抵接。这样通过主机1挤压第一连杆521的短边，就可以带动扭簧51转动积累弹性复位力。
本实施例中，为了让所述水箱本体3和主机1设置有定位件和定位配合件，用于将主机1定位在第一位置或第二位置。这样可以确保用户在使用时，不会因为误操作导致柔性储水囊4展开或者收缩。
本实施例中由于是依靠扭簧51带动连杆结构运动，扭簧51的力比较小。用户如果既要将主机1向上移动，又不需要柔性储水囊4展开，只需要用手握住柔性储水囊4外侧的挡板即可抵消扭簧51的复位力，使得柔性储水囊4不会展开。
由于需要将主机1定位在第一位置或者第二位置，因此所述定位件和定位配合件分为第一定位件和第一定位配合件，以及第二定位件和第二定位配合件；所述第一定位件为设置在水箱本体3的底盖32内壁上的第一凸起33，所述第一定位配合件为设置在主机1侧壁的第一凹槽11；所述第二定位件为设置在主机1侧壁的第二凸起12，所述第二定位配合件为设置在水箱本体3侧壁内表面的第二凹槽34。通过凸起和凹槽即可实现定位配合，并且这种定位配合所需要的解锁力也不会太强，既可 以避免误操作，同时也不会对用户正常操作主机1上下移动造成太大的不便。
所述主机1内设置有电机13和活塞泵组件14；所述活塞泵组件14的吸水端与所述水箱本体3连通，出水端与所述出水嘴2连通；所述电机13用于驱动活塞泵组件14中的活塞做往复运动。
以上所述，仅为本发明较佳的具体实施方式，但本发明的设计构思并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，利用此构思对本发明进行非实质性的改动，均属于侵犯本发明保护范围的行为。
工业实用性
本发明一种具有扩容水箱的口腔护理设备，其水箱本体通过换向件连接所述柔性储水囊，将主机相对于水箱本体的移动转换为柔性储水囊的展开或收缩，从而改变柔性储水囊的容积，进而改变整个口腔护理设备的容积。本发明设计巧妙、使用方便，具有良好的工业实用性。
