近些年来，中国飞速发展的经济使得人民生活条件和消费水平得到巨大提升，消费者消费开始转型和升级，人们倾向于追求更高品质的生活和更高端的产品体验，这提高了高端家电在大众消费者中的普及率。随着现代人生活节奏的加快，人们对吹风机也提出了更高的要求——低温、低噪、大风力，高速吹风机逐渐得到大众的青睐。

光耦于吹风筒中的应用

吹风机在我们日常生活中的应用非常广泛，也是我们日常生活必不可少的小家电之一。然而，在吹风机内部的电路板上，也需要使用到一些小巧而重要的元器件，比如光耦。光耦是一种能够将输入信号转换成输出信号的元器件，其作用在于将电气信号转换成光信号，从而实现电路的隔离和保护。

群芯微电子推出的光耦产品 QXM305X为随机相位600V高压可控硅光耦，在高速吹风机中主要实现低压侧控制端与220V（或110V）高压侧加热丝负载端的隔离和驱动。

推荐光耦型号如下
