Abstract

一种能够手动刷牙或电动刷牙的电动牙刷，它是在已有的刷毛、刷柄连接结构的牙刷中，设一电驱动装置。增加刷套与刷柄连接。将已有的刷毛植于刷杆一端，制成圆柱体刷毛，刷杆另一端接上刷杆齿轮，进入中空刷柄中，与驱动盒中的差速齿轮，电机齿轮连接。开关钮两端分别与电机的正、负极连接，通过开关钮，改变与电池正、负极接触，而变换电机顺、逆时针转向。人们手持刷柄，涂上牙膏，手动刷牙的同时，打开开关钮，转动刷套，实现电动刷牙。

Description

电动牙刷
本实用新型涉及一种牙刷刷毛存在的电动装置，尤其是能手动刷牙和电动刷牙的电动牙刷。
目前，公知的牙刷构造是有刷头、刷毛、刷柄组成。将刷毛涂上牙膏，手持刷柄，上牙从上往下刷，下牙从下往上刷，咬合面来回刷。但是刷牙全过程中，手动速度直接影响刷牙效果。人们使用普通牙刷在短时间内不能彻底清洁牙缝、牙龈与齿根结合部位的污垢，普通牙刷容易误导人们保持口腔清洁，长期因漱牙不净会引发口臭、蛀牙、色斑牙等疾病。
本实用新型的目的是提供一种电动牙刷，它不仅能涂上牙膏手动刷牙，而且能靠电驱动系统的设置，人们快速清洁牙齿、口腔。
本实用新型的目的是这样实现的：在空心塑料刷柄中，电动牙刷的刷毛植于刷杆的前端，刷毛排成圆柱体，刷杆的后端套刷杆齿轮，刷杆齿轮通过差速齿轮与电机齿轮连接。刷柄前端套一半敞口式刷套，套住刷毛，通过凹凸槽与刷柄连接。刷牙过程中，防止洗漱液进入驱动盒，人们可以转动刷套，使刷套敞口对要刷的牙面，而轻松刷牙。刷柄后端是长方体驱动盒，驱动盒内有电机，电池，开关钮。人们手持刷柄、驱动盒，将刷毛涂上牙膏，推动开关钮，可以改变电机齿轮顺、逆时针转向，带动刷毛，实现上牙从上往下刷，下牙从下往上刷，咬合面来回刷，不伤及牙龈。则能达到快速刷牙的目的。
由于采用上述方案，可以在刷牙同时，方便地提高刷牙速度，起到快速刷牙，洁齿的效果。牙刷体中，采用带刷毛的刷杆，刷套，空心刷柄，齿轮，电机，电池，驱动盒，结构简单。
下面结合附图和实施例对实用新型进一步说明。
(图一)是本实用新型的电路图。
(图二)是电动牙刷实施例的纵剖面构造图。
(图三)是(图二)的I-I剖视图。

在(图一)所示电路图中，5号电池(11)引出一个负极，二个正极。电机(8)的正、负极设置成开关钮(10)。开关钮向前推，电机逆时针转动。开关钮向后推与电池正、负极接触，电机顺时针转动。开关钮置于中间档为关闭状态。
在(图二)所示的实例中，刷杆(3)前端为刷毛(2)，刷毛长度为5-6毫米，刷毛由刷套(1)套住。刷杆，刷套要求用PP材质。刷杆后端为刷杆齿轮(5)，刷杆齿轮伸入中空刷柄(4)中，与驱动盒(12)中的差速齿轮(6)，电动齿轮(7)连接。如(图三)所示刷柄中设置的防护圈(15)，刷杆穿于其中，防护圈厚度为3毫米，刷柄截面直径为12毫米，刷杆截面直径为3毫米。刷柄下端有漏水孔(14)直径为4毫米，有效地防止水渗入驱动盒中。刷柄，驱动盒要求用卫生塑料制成。驱动盒中电机(8)与电池(11)，开关钮(10)，电池后盖(13)连接，通过电机的正、负极电极铜片(9)与电池的正、负极电极铜片变换接触，而实现电驱动。

Claims (2)
