The invention discloses an electric fan machine head positioning structure and an electric fan. The electric fan machine head positioning structure is connected between a machine head and a bracket, and further comprises a rotary part and a second rotary part, wherein the first rotary part is fixedly connected on the machine head; the second rotary part is fixedly connected on the bracket; the first rotary part is rotatably arranged relative to the second rotary part; and a concave and convex positioning structure for limiting a plurality of peripheral rotary positions, relative to the first rotary part, of the second rotary part is formed between the first rotary part and the second rotary part. According to the electric fan machine head positioning structure disclosed by the invention, the problem that the machine head positioning structure is inconvenient in mounting operation and complex in structure in the prior art can be avoided.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to an electric fan head positioning structure and the electric fan. Background technique [0002] At present, the positioning structure of the electric fan head on the market is composed of a spring, a steel ball and an angle limiter. During assembly, the adjusting steel ball is first loaded into the top of the spring, and then pressed into the angle limiter. When it is difficult to control, it is easy to cause the steel ball to be lifted or difficult to press into the angle limit piece. [0003] A utility model patent with Chinese patent number 200820202851.4 discloses a swing adjustment structure for an electric fan. The swing adjustment structure for an electric fan is composed of an angle positioning piece, a ball, and an adjustment spring. The head pitch adjustment is inconvenient to operate and install, and the adjustable angles that can be realized are limited. In addition, Ch...
