【发明内容】  [Summary of the Invention]
本发明所要解决的技术问题是提供一种使用方便、 自带牙齿清洁介质的 牙刷。  The technical problem to be solved by the present invention is to provide a toothbrush which is easy to use and self-contained with a tooth cleaning medium.
为解决上述技术问题, 本发明提供一种一体式牙刷, 包括带刷毛的刷头 和用于抓握的刷柄, 刷头的一端和刷柄的一端连接; 刷头和刷柄上均设有空 腔; 刷头上的空腔开口于刷头装设刷毛的部位和刷头的与刷柄连接的部位; 刷柄的空腔开口于刷柄的与刷头连接的部位, 刷柄的空腔容纳有可被压縮的 容器和可被使用者推动以压縮容器的推块; 容器设有开口, 容器的开口只与 刷头的空腔连通。  In order to solve the above technical problem, the present invention provides an integrated toothbrush, comprising a brush head with a brush and a handle for gripping, one end of the brush head is connected with one end of the handle; and both the brush head and the handle are provided The cavity on the brush head is open to the portion where the brush head is provided with the bristles and the portion of the brush head that is connected with the handle; the cavity of the handle is opened at the portion of the handle connected to the brush head, and the handle is empty The chamber houses a container that can be compressed and a push block that can be pushed by a user to compress the container; the container is provided with an opening, the opening of the container being in communication only with the cavity of the brush head.
本发明牙刷中, 容纳在刷柄空腔内的容器中可装填清洁介质 (如牙膏、 牙液等),容器的开口只与刷头的空腔连通,刷头的空腔开口于刷头装设刷毛 的部位, 当使用者推动推块时容器被推块压縮, 容器内的清洁介质被挤入刷 头的空腔内、 并经由刷头的空腔设于刷头装设刷毛的部位的开口被挤出到刷 毛部位, 清洁介质可与刷毛一起对牙齿进行清洁。  In the toothbrush of the present invention, the container accommodated in the cavity of the handle can be filled with a cleaning medium (such as toothpaste, tooth liquid, etc.), the opening of the container only communicates with the cavity of the brush head, and the cavity of the brush head is opened to the brush head. Where the bristles are located, when the user pushes the push block, the container is compressed by the push block, and the cleaning medium in the container is squeezed into the cavity of the brush head, and is disposed in the bristles of the brush head through the cavity of the brush head. The opening is extruded into the bristle area, and the cleaning medium cleans the teeth together with the bristles.
可以使容器的开口端的外部尺寸与刷头上的空腔开口处的腔体尺寸相 适配以使容器的开口端可插入刷头上的空腔。 这样可以使清洁介质顺利地进 入刷头的空腔, 并避免泄漏。 为此, 可将容器的开口端设计成与刷头上的空 腔开口处的腔体尺寸相适配的长嘴结构。 The outer dimension of the open end of the container can be made to correspond to the size of the cavity at the cavity opening in the brush head Adapted so that the open end of the container can be inserted into the cavity on the brush head. This allows the cleaning medium to smoothly enter the cavity of the brush head and avoid leakage. To this end, the open end of the container can be designed as a long nozzle structure that is adapted to the size of the cavity at the cavity opening in the brush head.
容器的开口只与刷头的空腔连通这样实现: 容器上设有连续的折边, 折 边位于刷头和刷柄二者的相应连接部位之间并被刷头和刷柄二者的相应连接 部位压紧。  The opening of the container is only communicated with the cavity of the brush head. The container is provided with a continuous folded edge, and the folded edge is located between the corresponding connecting portion of the brush head and the handle and is corresponding to both the brush head and the handle. The joint is pressed.
作为本发明的改进, 刷头上设有控制刷头的空腔导通 /关闭状态的开关。 使用时, 开关打开, 刷头的空腔处于导通状态, 清洁介质可经由刷头的空腔 设于刷头装设刷毛的部位的开口被挤出到刷毛部位; 非使用状态下, 开关关 断, 刷头的空腔处于关闭状态, 清洁介质不会漏出。  As an improvement of the present invention, the brush head is provided with a switch for controlling the opening/closing state of the cavity of the brush head. When in use, the switch is opened, the cavity of the brush head is in a conducting state, and the cleaning medium can be extruded to the bristle part through the opening of the cavity of the brush head provided at the portion where the brush head is provided with the brush; in the non-use state, the switch is off Broken, the cavity of the brush head is closed, and the cleaning medium does not leak.
控制刷头的空腔导通 /关闭状态的开关的优选设置位置设于刷头上的空 腔在刷头上的开口处。  A preferred position of the switch that controls the cavity on/off state of the brush head is provided at the opening in the head of the brush head.
作为优选, 控制刷头的空腔导通 /关闭状态的开关为单向开关, 单向开关 的导通方向为自刷头的空腔内部通向刷头外。 使用状态下, 当使用者推动推 块时容器被推块压縮, 容器内的清洁介质被挤入刷头的空腔内, 单向开关在 清洁介质的推力作用下被挤开而导通; 非使用状态下, 单向开关处于关闭状 态。  Preferably, the switch for controlling the on/off state of the cavity of the brush head is a one-way switch, and the conduction direction of the one-way switch is from the inside of the cavity of the brush head to the outside of the brush head. In the state of use, when the user pushes the push block, the container is compressed by the push block, the cleaning medium in the container is squeezed into the cavity of the brush head, and the one-way switch is squeezed and turned on under the thrust of the cleaning medium; In the non-use state, the one-way switch is off.
容器的优选结构形式为手风琴式折叠结构。 这样的结构便于推块对容器 进行推挤。  The preferred construction of the container is an accordion folding structure. Such a structure facilitates pushing the block to push the container.
作为一种具体形式, 刷柄上开设有长槽, 推块从长槽中露出。 推块从长 槽中露出的部分可供使用者手指推动推块, 便于使用。  As a specific form, the handle is provided with a long groove, and the push block is exposed from the long groove. The portion of the push block that emerges from the long slot allows the user to push the push block for easy access.
作为本发明进一歩的改进, 刷柄上长槽的一个或两个槽边为波浪形, 推 块的适当部位设有与波浪形槽边相适配的弹性卡头。 非使用状态下推块上的 弹性卡头位于槽边波浪相应位置的 "波谷" 中, 弹性卡头的弹力使得推块被 定位; 使用者推动推块时, 使用者的推力克服弹性卡头的弹力使弹性卡头发 生变形以越过槽边波浪相应位置的 "波峰", 推块的位置改变, 实现推块对容 器的推挤。 这样的结构可将推块定位, 便于使用者操作。  As a further improvement of the present invention, one or both of the groove sides of the long groove on the handle are undulating, and an appropriate portion of the push block is provided with an elastic chuck adapted to the undulating groove edge. In the non-use state, the elastic chuck on the push block is located in the "valley" of the corresponding position of the wave on the side of the groove, and the elastic force of the elastic chuck causes the push block to be positioned; when the user pushes the push block, the user's thrust overcomes the elastic chuck The elastic force deforms the elastic chuck to cross the "peak" of the corresponding position of the wave at the edge of the groove, and the position of the push block is changed to realize the pushing of the push block to the container. Such a structure can position the push block for user operation.
刷头的一端和刷柄的一端连接的方式可以为螺紋配合或卡式配合。 采用 螺紋配合是利用分别设于刷头和刷柄上的相适配的螺紋旋紧在一起而将刷头 的一端和刷柄的一端连接; 采用卡式配合是利用类似笔杆和笔帽之间的卡紧 配合方式将刷头的一端和刷柄的一端连接。 本发明的有益效果是: 清洁介质和牙刷一体, 不用另备清洁介质, 使用 方便, 结构简单, 容易实施。 本发明适用牙膏、 牙液等多种清洁介质。 装填 清洁介质的容器可一次性使用, 也可多次装填清洁介质重复使用。 One end of the brush head and one end of the handle can be connected in a threaded or carded manner. The threaded engagement is achieved by screwing one end of the brush head and one end of the handle with the matching threads respectively provided on the brush head and the handle; the use of the card fit is to use between the pen and the cap A clamping fit connects one end of the brush head to one end of the handle. The invention has the beneficial effects that: the cleaning medium and the toothbrush are integrated, no need for a separate cleaning medium, convenient to use, simple in structure and easy to implement. The invention is applicable to various cleaning media such as toothpaste and tooth liquid. Containers filled with cleaning media can be used at one time or repeatedly with cleaning media.
