MPL-B420P-HJ74AA

这里对结构作出一个肯定，整个拆解过程没有一颗螺丝，真心觉得结构做的很棒，因为一想到我们公司产品结构都喜欢多加几颗螺丝，就让人觉得头疼。

1、电动牙刷外观

2、从下面拆开，需要用到平口螺丝刀

3、牙刷底部标注有品牌、型号，输入5V/1A，防水等级IPX7（防水等级比较高的一种，表示防短时间浸水影响）

4、拆开后（电路板一侧）

5、拆开后（电池一侧）

3、主要构成

内部主要由电机Motor，电路板PCBA和电池组成。

1、电机也是结构直接固定就好，拆装也很方便，没有一颗螺丝（个人比较痛恨螺丝较多的产品，可能是EMC摸底需要不停拆装，把人给伤透了）。

电机的转子安装了一个偏心块，由于不对称，在转动时重心偏离轴承，实现了牙刷全身的转动。

2、PCBA生产日期是20201226，两年以前的产品，具体功能及作用，我们在后进行分析。

3、电池用的18650 1500mAh 3.7V锂电池，电池充满后电压为4.2V（实测4.13V）感觉充一次电要用好几周时间（具体忘记了，反正电池挺的）。
