    Abstract: An electric fan comprises a blower motor (10) and two oscillation motors (2,3) combined with a guide plate (5) and a support (14). The two oscillation motors (2,3) are disposed at the back of the blower motor(10). One motor (3) is mounted at the longitudinal board (2.36).The engaging post (33)of the crank arm (32) is connected with an end hole (351)of the connecting lever (35) and another end hole (352) of the connecting lever(35) is fix at the back seat (143) of the support(14) by screw. The front arm (140) of the support (14) at the two sides of the blower motor(10)is pivotd with the blower motor(10) and the pivot is the longitudinal oscillation shaft. Another motor (2) is mounted at the center of the horizontal board(2.35). Its transmiting shaft (21) extending downward is inserted into the transverse oscillating crank arm (21) and the another end shaft (23)of crank arm (22) is guided by the groove (590)of the guide plate (5) as the transverse oscillation shaft.The fan can oscillate in the transverse and longitudinal directions and blow air simultaneously.
