The utility model relates to a wind hood for a power assembly of a low pressure dust collector, which comprises a shell and a cover body formed in one. The shell is a hollow cylinder, the front of the shell is connected with the cover body and the rear is opened, and the motor and impeller are opened from the rear opening to the inner cavity of the shell, the cover is a round platform, and the center of the cover is equipped with an inlet connecting with the inner chamber of the shell. The air outlet is arranged around the center axis of the shell, the shell is used to install the motor and the impeller, and the motor drives the impeller to rotate. The wind is discharged from the inlet of the hood and the inner heat of the shell is discharged from the outlet. Compared with the existing structure of the casing or the wind hood, the utility model wind shield improves the air duct structure. At the same time, the function of the motor shell and the wind hood can be realized at the same time, which can increase the suction, improve the efficiency of the assembly, reduce the noise, reduce the material cost, and make it easy to install and use.
【技术实现步骤摘要】
一种低压吸尘器动力总成的风罩
本技术涉及吸尘器领域,具体涉及一种低压吸尘器动力总成的风罩。
技术介绍
吸尘器是一种常见的家用电器,其工作原理是,利用马达带动叶片高速旋转,在密封的壳体内产生负压,空气吸取尘屑,现有技术中,吸尘器的动力总成一般由马达和叶片组成,马达都会在外周侧安装机壳,而叶片则会在外周侧安装风罩,机壳起保护固定马达内部的转子、换向器、定子的作用,风罩起保护叶片引导风流的作用,两者缺一不可,但机壳和风罩两个零件在生产使用时,单独制作、分开安装,材料成本负担较重,安装费时,且风罩采用传统结构,噪音比较大,不能满足生产需要。
技术实现思路
针对现有技术中所存在的缺陷,本技术提供了一种在低压吸尘器动力总成中集机壳与风罩功能于一体的风罩,具体技术方案如下:一种低压吸尘器动力总成的风罩,包括一体成型的壳体和罩体,壳体为中空圆柱体,壳体前方连接罩体而后方开口,马达和叶轮从后方开口进入安装于壳体内腔,罩体为圆台形,罩体中心处设有与壳体内腔相通的进风口,壳体外周侧设有出风口,出风口围绕壳体中心轴圆周排列。作为本技术的一种优选方案,所述罩体与壳体连接处圆弧过渡。本技术的有益效果:集合了马达机壳与风叶风罩的功能,壳体用于安装马达和叶轮,马达驱动叶轮转动,风从罩体的进风口进入后带走壳体内部热量从出风口排出,相对于现有的机壳或风罩结构,本技术风罩改善风道结构,一次安装就可同时实现马达机壳与风叶风罩的功能,增加吸力、提高总成装置效率,降低噪音,减少材料成本,安装使用方便。附图说明图1是本技术风罩的立体图;图2是本技术风罩的主视图;图3是本技术风罩的剖视图;图4是本技术风罩内部安 ...
