Description

一种风机模组的旋转供电结构 技术领域
本实用新型涉及一种风机领域，更具体地说，涉及一种风机模组的旋转供电结构。
 背景技术
现有的风机只能出冷风，暖风机是由通风机、电动机及空气加热器组合而成的联合机组，通过空气加热器生热，然后由风机将加热后空气从出风口吹出至室内，带来室内温度上升。这种传统的暖风机，既需要空气加热器，又需要风机，为了将热量从发热电阻元件传递给空气，还需要散热片。这就使得整个暖风机占用的空间较大，且散热性能有待进一步提升，同时，整个暖风机的生产制作成本偏高。
申请号为201910735526.7的中国发明专利申请文件，公开了一种扇叶及应用该扇叶的冷暖两用风扇，该扇叶包括以自恒温的PTC发热体构成扇叶的方式或者以自恒温的PTC发热体设置在扇叶体上的方式中的任一种方式形成热交换体，在通电旋转后以吹出热风。
目前，对于风机旋转式的负载，需要解决将电能从静止端（固定端）传送至旋转端的问题。解决这个问题当前有三种常用的方式，即无线供电、电刷供电、滑环供电。
采用无线供电的方式，存在以下问题：1.供电效率低下，电能的损耗过大；2.技术复杂，需要线圈的耦合，这导致需要额外空间放置耦合线圈，不利于产品的小型化。
采用电刷的方式，存在以下问题：接触摩擦大、电刷易磨损、噪音大、使用寿命短、需要频繁更换电刷。另外，对于高转速的应用不适应，因为转速过高会产生磨损使得电刷失效，难以稳定供电。
采用滑环的方式，会因为滑环的结构限制使得旋转速度较低，无法适应高速旋转的应用。
