Description

一种新型电动牙刷 技术领域
本实用新型属于一种牙刷， 尤指一种新型的电动牙刷。
背景技术
牙刷已成为了人们日常生活中必不可少的牙齿清洁工具， 根据不同人群的使用习惯， 牙 刷被设置成不同的形状和样式， 比如刷部的刷毛就有波浪形的、 平整形的、 柔软的、 较硬的 说
等， 手柄就有弧形的、 波浪形的、 直棒形的等。 这些牙刷大都是手动牙刷， 使用起来不太方 便。 而对于一些电动牙刷， 由于其是由电机进行驱动， 牙刷震动速度慢， 耗电量大， 达不到 节能环保的目的。 书 技术方案
针对以上技术存在的不足， 本实用新型提供了一种新型电动牙刷， 该电动牙刷所具有的 摆动装置， 能有效解决上述问题。
本实用新型采取的技术方案如下：
一种新型电动牙刷， 包括刷部、 手柄外壳、 支架、 驱动电路和摆动装置。 所述摆动装置 包括摆动连接杆、 线圈、 模套、 硅钢片、 滚珠轴承和轴承支座， 其中， 摆动连接杆的一端为 永磁体， 另一端为扁平结构， 该端与刷部连接， 刷部可自由取出。 两片硅钢片竖立在线圈的 两侧， 用一模套将其固定在一起， 从而形成一槽， 永磁体就置于该槽内。 永磁体的两端各套 设一个滚珠轴承， 滚珠轴承则固定在轴承支座中。 通过螺钉把轴承支座和模套连接起来， 从 而把摆动连接杆、线圈和硅钢片固定在一起， 摆动连接杆以两个滚珠轴承为支点可进行摆动。
摆动装置置于支架内部， 驱动电路的输出端与线圈通过导线连接起来， 其输入端则连接 至电源， 电源也置于支架内。 手柄外壳包覆在支架外， 与刷部形成密闭连接。
驱动电路包括档位控制模块， 可对摆动装置的震动频率进行调整控制。
本实用新型的有益效果在于： 所采用的摆动装置， 其摆动速度快、 耗电量低； 驱动电路 设有的档位控制模块， 可实现不同的震动频率， 以适合不同的人使用； 刷部可自由取出， 更 换方便。

30 轴承支座， 40 硅钢片，
50 模套， 60 线圈，
70 驱动电路， 80 支架，
90 手柄外壳， 100 刷部，
101 永磁体。
具体实施方式
下面将结合附图对本实用新型作进一步描述：
如图 1所示的本实用新型的爆炸图， 图中， 一种新型电动牙刷， 包括刷部 100、手柄外壳 90、 支架 80、 驱动电路 70和摆动装置。 所述摆动装置包括摆动连接杆 10、 线圈 60、 模套 50、 硅钢片 40、 滚珠轴承 20和轴承支座 30。 其中， 摆动连接杆 10的一端为永磁体 101， 另一端为扁平结构， 该端与刷部 100连接， 刷部 100内设有与该扁平结构相适配的槽孔， 当摆动连接杆 10摆动时， 可带动刷部 100—起 摆动。 刷部 100可自由取出， 便于更换。 两片硅钢片 40竖立在线圈 60的两侧， 用一模套 50 将其固定在一起， 从而形成一槽， 永磁体 101就置于该槽内。 永磁体 101的两端各套设 水 滚珠轴承 20， 滚珠轴承 20则固定在轴承支座 30中。 通过螺钉把轴承支座 30和模套 50连接 起来， 从而把摆动连接杆 10、 线圈 60和硅钢片 40固定在一起， 摆动连接杆 10以两个滚珠轴 承 20为支点可进行摆动（参见图 2)。所述摆动装置置于支架 80内部， 驱动电路 70的输出端 与线圈 60通过导线连接起来，其输入端则连接至电源，电源可采用一节可充电的五号干电池， 也置于支架 80内。 手柄外壳 90包覆在支架 80外， 与刷部 100形成密闭连接， 防止刷牙时水 从连接的缝隙处渗入牙刷内部。驱动电路 70包括档位控制模块， 可对摆动装置的震动频率进 行调整控制。 通过软件设置， 可分为慢、 中、 快三个档位， 人们通过一个按键对所述档位进 行切换， 选择适合自己的震动频率， 再进行刷牙， 所以该电动牙刷能适用于不同的人。 驱动 电路 70中还包括充电模块和指示模块， 电源的电能快耗尽时， 指示模块显示相应电量不足的 信号， 用户只需把牙刷插入相应的充电插座内， 牙刷即可自行进行充电。 指示模块还能指示 当前的使用档位， 充电已满等情况。
下面就其工作原理进行描述：
打开开关， 电路导通， 电流流入驱动电路 70， 驱动电路 70把输入的直流电转换成高频 交变电流， 高频交变电流流入摆动装置中的线圈 60， 使线圈 60周围产生变化的磁场， 由电 磁感应的原理，摆动连接杆 10上的永磁体 101会受到不同的作用力而发生左右摇摆的高频震 动， 进而带动刷部 100进行左右摇摆的高频震动。 由于摆动装置的可控性较好， 摆动连接杆 10不用像电机那样进行一个圆周的转动， 只需进行小角度的左右摆动， 所以震动频率很高， 速度很快， 而且耗电量很低。 通过按下档位切换键， 改变驱动电路 70输入线圈 60的电流， 即可实现震动频率的改变。
当然， 以上的实施例只是在于说明而不是限制本实用新型， 以上所述仅是本实用新型的 较佳实施例， 故凡依本实用新型专利申请范围所述的方法所做的等效变化或修饰， 均包括于 本实用新型专利申请范围内。
