充电式手持电动喷枪
技术领域
本发明属于喷枪技术领域,特指一种充电式手持电动喷枪。
背景技术
目前,喷枪是一种对涂料进行雾化处理,进而对被涂装工件表面进行喷涂而获得美观、均匀的涂覆层的喷涂设备。喷枪的雾化效果对喷涂的工件表面的效果起到非常重要的效果。
专利号:200510076514.6公开的喷射枪,其结构是:喷射枪可以通过以枢转配置安装在套筒上的杆驱动,套筒容纳雾化喷嘴,并且气流可以通过对应于喷射枪的空气涡轮产生,空气涡轮及其马达在与载有雾化喷嘴的套筒相对的手柄的一侧上同轴或几乎同轴布置在喷射枪雾化喷嘴上,使得来自空气涡轮的气流以直线或几乎直线方向供应通过雾化喷嘴的套筒,在空气涡轮设置有消声器,以降低高速转动的空气涡轮产生的噪音,安装、维护复杂,生产、使用成本高。专利号:201110005569.3,公开的一种手持式喷枪,包括有枪体、喷壶,连接枪体和喷壶的基座以及壳体,所述枪体前端设置有一喷嘴,所述壳体上部成型有一腔体,壳体下部成型有一扳手,所述腔体与枪体联通连接,所述腔体内设置有电机。电机采用一种新型的电机结构,将定转子组件(定子和转子)设于风叶的进风面侧,也即将定转子组件设于进风口,对定转子组件进行冷风强制制冷,提高散热效果,这种散热结构比较复杂,噪音较大。同时,上述两个专利中均未设置单向阀,在停止喷射后,喷壶内的物料会出现倒流的现象,严重影响了产品的品质。传统的喷枪的电源都是通过插头插在插座上进行供电,这样使用范围具有很大的局限性,特别是在一些使用范围比较大的情况下,需要通过转接插座来实现电连接,使用不方便。
