Description

一种电动牙刷 技术领域
本实用新型涉及牙刷制造的技术领域，尤其是涉及一种电动牙刷。
背景技术
电动牙刷是一种采用微型电机驱动刷头运动的牙刷，其刷头的运动通常有两种方式，一种是旋转方式刷牙，另一种是摆动方式刷牙。摆动方式通常结构较复杂、制造成本、售价高，因此，其市场销量受到一定局限。刷头旋转方式的电动牙刷，利用现有电子变速技术可做成结构简单的结构。
目前市面上所见到的刷头旋转的电动牙刷大部分采用刷毛“绕垂直轴线转动”的方式，但是这种刷毛绕垂直轴线转动的运转方式与口腔保健中正确的竖刷法不相符，因而其清洁牙齿的效果并不理想。而且，市面上销售的电动牙刷还没有见到具备有冲洗牙齿的功能的电动牙刷，还没有完全实现自动化，造成刷牙的舒适感差。
如果有一款电动牙刷能结合口腔保健液的冲洗，达到更好的牙齿清洁效果，那将会受到市场的青睐。
发明内容
为了解决上述问题，本实用新型提供了一种电动牙刷，包括刷柄、刷头和刷杆，这种电动牙刷采用刷毛绕水平轴线转动的运动方式，结合口腔保健液对牙齿的冲刷清洗，能够有效地清除牙齿上和牙间缝的异物，提高口腔保健和护理的质量。
为实现上述目的，本实用新型提供了如下技术方案：
一种电动牙刷，包括刷柄、连接件、刷头和刷杆，刷柄的表面设置有运行按键，刷柄内部设置有电源、电机和传动轮，电源和电机是电连接的；连接件则通过传动轮和电机连接，刷头又通过连接件和刷柄连接，刷头的刷毛为轮形螺旋状。运行按键上有开关按键，也设置有刷头正转和刷头反转的模式按键。刷毛设计成轮形螺旋状，实现了刷毛绕水平轴线转动的运转方式，在刷牙时可产生显著的竖刷效果，很好地清除牙齿上和牙间缝的异物。
电动牙刷的刷杆在内部设置有液体管道，刷杆在刷头的上方设置有护颊罩，所述的液体管道在护颊罩的内侧壁处开设有出液孔，所述的液体管道在刷杆的尾端设置有进液口，所述的进液口通过连接管和压力供液器或者家用水阀相连。进液口如和家用水阀，即水龙头相连接，则使用的是自来水；如和压力供液器相连，压力供液器向液体管道输送口腔保健液，通过调节供液器的供液压力，可以调整口腔保健液的冲洗力度。口腔保健液具有消毒、杀菌 和清洁牙齿等功能，比如漱口水、口腔消毒液和液体牙膏等。
作为上述的本实用新型的技术方案的进一步描述，所述的出液孔为30～50个，可以有效保证冲洗液体对牙齿的冲刷或者喷刷的清洁效果。
电动牙刷的刷头的刷毛可进行正向或者反向运转。使用者可以根据喜好，调整刷毛的运转方式。
作为上述的本实用新型的技术方案的进一步描述，所述的刷头的刷毛的长度为25.0～35.0mm，刷毛的刷毛旋数为4～6旋，所述的刷毛的毛旋间距为3.5～4.5mm。研究人员发现，按照本技术方案制作出来的刷毛，尤其是精心设计了毛旋间距和刷毛旋数，规范了排列空间和距离，使刷毛能自由地进入到其他牙刷无法刷到的牙间隙和牙缝隙。
作为上述的本实用新型的技术方案的进一步描述，所述的护颊罩的宽度为20～25mm，所述的护颊罩的长度为30～35mm，所述的出液孔的孔径为1.0～2.0mm。护颊罩由软质弹性材料制成，可遮挡旋转的刷头，避免对口腔壁的粘膜壁造成损伤，提高刷牙舒适感。
基于上述的技术方案，本实用新型取得的技术效果为：
(1)本实用新型提供的电动牙刷通过将刷毛设计成轮形螺旋状，实现了刷毛绕水平轴线转动的运转方式，在刷牙时可产生显著的竖刷效果，同时结合刷杆出液孔喷刷或冲刷出的口腔保健液，能很好地清除牙龈、牙齿上和牙间缝的异物。在具有消毒、抑菌和洁牙的口腔保健液的冲洗运用上，进一步提升了电动牙刷的自动化程度，使刷牙成为一种舒适的享受。
(2)本实用新型的电动牙刷的刷头通过连接件和刷柄连接，连接件固定在刷柄上，可轻易插拔更换刷头，而且不易造成连接的松动，这样就提高了电动牙刷的使用寿命和方便度。同时，该电动牙刷的成本和造价低，使用者乐于接受，更容易推广和普及应用。
