The centrifugal fan capable of reducing noise comprises a pushing frame, universal wheels are fixed to the four corners of the bottom end of the pushing frame, a pushing plate is fixed to one side of the upper surface of the pushing frame, sinking grooves are formed in the two sides of the upper surface of the pushing frame, and positive and negative screw rods are rotationally installed in the two sinking grooves through bearings; and motors are fixed in the upper surface of the push frame and located on the side edges of the two sinking grooves. According to the centrifugal fan capable of reducing noise provided by the invention, when a user needs to use the fan body, two motors can be started to drive two positive and negative screw rods to rotate, and when the positive and negative screw rods rotate, positive and negative threads outside the positive and negative screw rods drive positioning seats on two sides outside the positive and negative screw rods to be in threaded connection; and after the positioning seat is subjected to threaded translation, two X-shaped brackets formed by the four inclined supporting rods can rotate so as to jack up the top plate above, and at the moment, the user can adjust the height of the fan main body by controlling the rotation of the motor.

    本发明提供一种可降噪的离心风机,包括推架,所述推架的底端四角均固定有万向轮,所述推架的上表面一侧固定有推板,所述推架的上表面两侧均开设有沉槽,两个所述沉槽的内部均通过轴承转动安装有正反螺杆,所述推架的上表面内部且位于两个所述沉槽侧边均固定有电机。本发明提供的一种可降噪的离心风机使用者在需要使用风机主体时,可以通过启动两个电机,通过两个电机带动两根正反螺杆进行转动,而当正反螺杆转动其外部的正、反螺牙便会带动其外部两侧的定位座进行螺纹连接,而当定位座进行螺纹平移后则四根斜撑杆形成的两个X形支架便会进行转动从而将上方的顶板进行顶起,这时使用者可以通过控制电机的转动从而进行调节风机主体的高度。
