Description

可伸缩型牙间刷 技术领域
本发明涉及一种口腔清洁用工具，特别是用于清洁牙齿间隙的牙间刷。
背景技术
由于年龄增长、病理性等原因，很容易造成牙龈萎缩、牙齿间隙扩大，极易造成食物的残留，如果不能及时清洁，一方面会产生口腔异味，另一方面容易导致各种牙病、口腔疾病，特别是牙周炎的发生。
针对这种情况，目前市场上研制了各种牙间刷，或称齿间刷，供使用者选择。虽然现在市场上存在各种结构、不同规格的产品，但现有产品普遍存在不易对准牙缝，不易观察牙缝的缺点。而且在外出时，携带不方便，使用完毕后收纳也不方便。尤其是在清洁第三磨牙与第二磨牙之间的牙缝、或第二磨牙与第一磨牙之间的牙缝、或第一磨牙与第二前磨牙之间的牙缝时，由于所需清洁牙缝位置处于口腔深处，现有技术的牙间刷的刷体分通常采用金属丝缆附着高分子材料纤维的毛刷结构，因此在凭感觉进行操作时，金属丝非常容易刺伤牙龈组织。
针对现有技术的牙间刷在清洁磨牙之间的牙缝时，存在牙间刷难以进入牙缝、易刺伤牙龈，外出携带和使用不便的缺点，因此，需要对现有的牙间刷进行改进。
发明内容
本发明之可伸缩型牙间刷通过伸缩机构的特别设计，牙间刷推出即可使用，收回后，牙间刷放置在手柄的纳物空间内，可形成一个小巧的器械盒，非常便于携带。尤其是本发明之可伸缩型牙间刷可以和内置式牙间刷配合使用，使用过程中，内置式牙间刷的递送器出口可以直接顶住牙缝，将牙间刷从递送器中推出即可直接进入牙缝内，尤其适合于对口腔深处磨牙的清洁，很好地解决了现有牙间刷容易刺伤牙龈组织的问题。

具体实施方式
实施例：含内置式牙间刷的本发明之可伸缩型牙间刷
参考图1至图4，本发明之可伸缩型牙间刷含牙间刷100、伸缩机构200及手柄300。
本实施例中，所述牙间刷100是内置式牙间刷101。
所述内置式牙间刷101含刷体11和递送器12，所述刷体11可运动地内置在所述递送器12前端的弯管12-1内。所述刷体11的工作部11-1在外力作用下可从所述弯管12-1内伸出或退回。
参考图2和图4，本实施例中，所述刷体11为直线型，采用弹性材料制造；所述刷体11在发生弹性变形后能安装在所述弯管12-1内，当所述刷体11从所述弯管12-1伸出后，所述刷体11又能恢复或基本恢复直线型。
所述弹性材料选自：弹性高分子材料、或弹性金属材料。如：采用弹性高分子材料制造所述刷体11的工作部11-1的纤维或凸起11-11，而采用弹性金属材料制造所述刷体11的连接体11-2，通过在金属模具中注塑成型的工艺，将弹性金属材料制造的连接体11-2与弹性高分子材料制造的纤维或凸起11-11组成一个整体，形成所述刷体11，这样复合结构的牙间刷既保证了所述刷体11的工作部11-1的柔软性，又保持了所述刷体11整体的弹性和适度的刚性，具有良好的力的传递性。
参考图5，所述刷体11也可以是弧线型。当所述刷体11从所述弯管12-1伸出后，所述刷体11呈弧线型，所述弧线型可以设计成与牙齿外部轮廓接近的弧形。
所述刷体11还可以是采用可塑形的材料制造，如利用细钢丝制造所述刷体11的连接体11-2，根据牙齿外部轮廓，可以预先对所述刷体11的连接体11-2进行一定程度的塑形，当所述刷体11的工作部11-1从所述弯管12-1中伸出后，可以基本保持预先设定的形状。
当然本领域的技术人员还可以根据需要设计不同类型的刷体，申请人在此不一一举例说明，但都不脱离本申请的保护范围。
本实施例中，所述伸缩机构200是滑动型伸缩机构201。所述滑动型伸缩机构201含滑槽21和滑块22。推动所述滑块22沿所述滑槽21往复运动，就可以将所述牙间刷100从所述手柄300内伸出或收回。
所述滑槽21设置在所述手柄300的壳体32上，所述滑块22通过连接端22-1和所述 牙间刷100的连接部13连接，将所述牙间刷100和所述伸缩机构200连接成一个整体。
为保证所述牙间刷100伸出所述手柄300后能固定在所述手柄300外，所述滑槽21的上端部设有止锁块21-1，为保证所述牙间刷100收回所述手柄后能固定收纳在所述手柄300内，在所述滑槽的下端部设有限位块21-2。当向上推动所述滑块22时，所述滑块22越过所述止锁块21-1时，可将所述牙间刷100被固定在所述手柄300外，可以防止清洁过程中所述牙间刷100向所述手柄300内滑动。当向下推动所述滑块22时，所述滑块22越过所述限位块21-2时，所述牙间刷100就被固定在所述手柄300的纳物空间31内，防止携带过程中所述牙间刷100滑出所述手柄300。
所述伸缩机构200也可以是旋转型伸缩机构，如采用螺纹螺杆的运动方式，通过旋转所述伸缩机构200将所述牙间刷100从所述手柄300中推出或收回。当然，本领域的技术人员还可以根据需要设计出不同结构的所述伸缩机构200，都并不脱离本申请的保护范围。
本实施例中，所述内置式牙间刷101的递送器12通过所述连接部13以粘接的方式固定安装在所述伸缩机构200上，清洁完毕后只需要更换所述刷体11即可，既满足了定期更换工具，方便清洁的卫生要求，又可以防止在清洁过程中所述牙间刷100从所述伸缩机构200上脱落，使用过程非常安全。
所述牙间刷100还可以通过整体制造、超声焊接等各种方式固定连接在所述伸缩机构200上，申请人在此不一一列举，但都不脱离本申请的保护范围。
当使用普通牙间刷100时，为方便更换所述牙间刷100，所述牙间刷100可通过凹凸卡配合连接方式、或螺纹连接方式、或过盈配合连接方式等多种连接在所述伸缩机构200上，申请人在此不详细说明。
组装时，首先将所述手柄300的底盖33取下，将所述牙间刷100和所述伸缩机构200连接在一起，将所述牙间刷100和所述伸缩机构200一起从所述手柄300的底部置入所述纳物空间31内，将所述伸缩机构200的滑块22安装在所述滑槽21内，装上所述底盖33即可。
使用时，向上推动所述滑块22，将所述内置式牙间刷101从所述手柄300中推出。然后先将所述刷体11退回所述递送器12前端的弯管12-1内，将所述递送器12前端的弯管12-1出口顶住需要清洁的牙缝处，再推动所述刷体11，所述刷体11的工作部11-1从所述弯管12-1中伸出并进入牙缝，即可对牙缝进行清洁。这样，可以很好地解决现有牙间刷难以对准牙缝，容易刺伤牙龈组织的问题。
使用完毕后，只需向下推动所述滑块22，所述滑块22即可带动所述内置式牙间刷101向下运动，所述内置式牙间刷101被收回所述手柄300的纳物空间31内。所述手柄300 即可形成一个小巧的器械盒，非常便于携带和所述牙间刷100的收纳。
本实施例之可伸缩型牙间刷由于采用了内置式牙间刷，具有使用方便、安全，易于收纳、携带的多项优点。
应该注意，本文中公开和说明的结构可以用其它效果相同的结构代替，同时本发明所介绍的实施例并非实现本发明的唯一结构。虽然本发明的优先实施例已在本文中予以介绍和说明，但本领域内的技术人员都清楚知道这些实施例不过是举例说明而己，本领域内的技术人员可以做出无数的变化、改进和代替，而不会脱离本发明，因此，应按照本发明所附的权利要求书的精神和范围来的界定本发明的保护范围。
