The invention relates to an electric tool for environmental care in daily life, in particular to a blowing suction machine. The blowing suction machine comprises a volute with an air inlet and an airoutlet, an air outlet pipe in seal connection with the air outlet, an air tube communicating with the volute, a handle, a trigger, a motor, a power source component and a centrifugal air fan, whereinthe handle, the trigger, the motor and the power source component are arranged outside the volute, the centrifugal air fan is inside the volute, when the handle is held by hands to pull the trigger, the motor is electrically connected to the power source component, and the centrifugal air fan is driven to rotate, air enters the volute through the air inlet and is compressed to the air outlet pipeby the air fan, the centrifugal air fan is composed of a panel, a bottom plate and a plurality of spiral blades, and the volute is internally provided with a sealing rib with the circle center being same as the panel and the inner diameter being larger than the panel diameter. By means of the blowing suction 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。
