背景技术Background Art
电动牙刷是通过电动机芯的快速旋转或振动,使刷头产生高频振动,瞬间将牙膏分解成细微泡沫,深入清洁牙缝,与此同时,刷毛的颤动能促进口腔的血液循环,对牙龈组织有按摩效果,电动牙刷有两大类:旋转与振动,旋转类的牙刷原理简单,就是电动机驱动圆形刷头旋转,在执行普通刷牙动作的同时加强摩擦效果,旋转类的牙刷力度大,牙面清洗很干净,牙缝清洗相对较弱。An electric toothbrush uses the rapid rotation or vibration of the motor core to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth and have a massage effect on the gum tissue. There are two major types of electric toothbrushes: rotary and vibrating. The principle of a rotary toothbrush is simple, that is, the motor drives the round brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. A rotary toothbrush has great power and cleans the tooth surface very well, but the cleaning of the gaps between teeth is relatively weak.
通常使用的电动牙刷包括牙刷柄和牙刷头,牙刷柄可以循环使用,而牙刷头需要定期进行更换,生活中常用的电动牙刷,其可拆卸的牙刷头一般包括头部和颈部,二者一体式连接,安装时颈部与牙刷柄进行连接,在更换时需要将头部与颈部一同更换,作为消耗品的牙刷头耗材较多,造成资源的浪费。A commonly used electric toothbrush includes a toothbrush handle and a toothbrush head. The toothbrush handle can be recycled, while the toothbrush head needs to be replaced regularly. The detachable toothbrush head of an electric toothbrush commonly used in life generally includes a head and a neck, which are connected in one piece. The neck is connected to the toothbrush handle during installation, and the head and neck need to be replaced together during replacement. As consumables, the toothbrush head has many consumables, resulting in a waste of resources.
