Abstract

The invention discloses an air blowing and suction conversion device and a corresponding air blowing and suction fan. The air blowing and suction conversion device comprises a main shell, a motor and a fan which are arranged in the main shell, and further comprises a conversion frame, and the conversion frame comprises a first channel, a second channel and a third channel; the main shell comprises an air inlet and an air outlet, the conversion frame is connected with the main shell, the conversion frame and the main shell can axially move under the condition that the connection is not disconnected, so that the switching between an air blowing mode and an air suction mode is carried out, in the air blowing mode, the air inlet is communicated with the first channel, and the air outlet is communicated with the second channel; and in the air suction mode, the air inlet is communicated with the second channel, and the air outlet is communicated with the third channel. Blowing and sucking function conversion is achieved in a translation mode, the structure is simple, operation is easy, and use difficulty is avoided.

Description

technical field [0001] The invention relates to the technical field of cleaning tools, in particular to a blowing and sucking wind converting device and a blowing and sucking fan. Background technique [0002] When cleaning dust, waste, leaves and other garbage, the fan structure with blowing and suction function is generally used for cleaning. The motor, the fan driven by the motor and the handle connected to the main casing, etc. The blowing and absorbing parts generally include the blowing pipe and the suction pipe connected to the air duct. The blowing and suctioning machine needs to have both blowing and suction functions. At present, in the axial flow In the structure of the fan blowing and sucking in the same pipe, one solution is to realize the forward and reverse rotation of the motor. The defect of this solution is that the performance of suction or suction is weak; the other solution is to realize the conversion of blowing and suction by rotating the motor assembl...
