Abstract

The invention discloses a left and right rotating adjusting mechanism for a fan and belongs to the technical field of fans. The mechanism comprises a base, wherein the base comprises an upper base and a lower base; the upper base is rotationally connected with the lower base; a motor is fixed on the upper base; an output shaft of the motor is fixed with one end of a connecting piece; the other end of the connecting piece is hinged with one end of a connecting rod; and the other end of the connecting rod is hinged on the lower base. The motor is subjected to reaction force of the connecting piece while driving the connecting piece to rotate, and the upper base is pushed to rotate relative to the lower base so as to rotate the fan left and right. The mechanism has a simple structure, and wind resistance is not formed during air exhaust of the fan.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a fan left and right rotation adjustment mechanism for adjusting the left and right rotation of the fan. Background technique [0002] There is a certain angle range for the fan to blow air, so when there are many people using the fan, some people will not be able to blow it. In order to solve this problem, the fan is generally equipped with a left and right rotation mechanism. The left and right rotation mechanism of the fan can drive the fan head to rotate back and forth, so that all people within a certain angle range can be blown to. At present, there is also a fan with a reversing piece installed on the air outlet side of the fan head. The reversing piece is provided with a baffle at a certain angle to the air outlet direction. There are openings between the baffles. Rotating with the fan blades, the airflow blown out by the fan passes through the port, is reversed by the reve...
