the plurality of air guide blades 120 are distributed along the height direction of the fan 100, and the air guide blades 120 are rotatably connected with the blade mounting frame along the width direction of the air sweeping opening, so that the inclination angle of the air guide blades 120 changes when the air guide blades rotate relative to the blade mounting frame, and the angle of the upper air guide and the lower air guide changes. The blade link 130 is rotatably connected to the rotation driving portion 126 of each wind guide blade 120, so that the blade link 130 can drive the rotation driving portions 126 to be linked. The driving assembly can drive one air guide blade 120 to rotate, and when one air guide blade 120 rotates, the blade connecting rod 130 drives the plurality of air guide blades 120 to be linked, so that synchronous adjustment of the vertical wind sweeping angles of the plurality of air guide blades 120 is realized, and the vertical wind sweeping angles are conveniently adjusted by outputting rotary driving force through the driving assembly.
