The invention relates to an electric tool for environment care in daily life, in particular to a blowing and sucking machine. The blowing and sucking machine comprises a volute with an air inlet and an air outlet, an air outlet pipe connected with the air outlet in a sealed mode, an air duct communicated with the volute, a handle arranged outside the volute, a trigger, a motor, a power source component and a centrifugal fan arranged in the volute; and when the trigger is pulled by holding the handle with a hand, the motor is electrically communicated with the power supply component and drivesthe centrifugal fan to rotate, air enters the volute through the air inlet and is compressed to the air outlet pipe by the fan, the centrifugal fan is composed of a panel, a bottom plate and a plurality of spiral blades, and a sealing rib concentric with a panel and having an inner diameter larger than the diameter of the panel is arranged in the volute. Through the blowing and sucking machine, noise can be greatly reduced, and the compression efficiency is improved.
本发明涉及一种日常生活中环境护理的电动工具，尤其涉及一种吹吸机，包括具有进风口和出风口的蜗壳、与出风口密封连接的出风管、与蜗壳连通的风筒、设于蜗壳外的把手、扳机、电机、电源组件和蜗壳内的离心式风扇，当手握把手扣动扳机时，电机与电源组件电连通，并带动离心式风扇旋转，空气经由进风口进入蜗壳内，被风扇压缩至出风管，所述离心式风扇由面板、底板和若干螺旋状叶片构成，蜗壳内部设有与面板同圆心、内径大于面板直径的密封筋。本发明的吹吸机能使噪音大大降低并使压缩效率提高。
