Abstract

The invention discloses a fan. The fan comprises a base, a connecting head, a fan head and an adjusting piece, wherein a connecting head mounting groove is formed in the base; at least one part of the connecting head is rotationally matched in the connecting head mounting groove, and the rotating axis is oriented in the horizontal direction; the fan head is arranged on the connecting head; the adjusting piece is rotationally arranged on the connecting head; one of the adjusting piece and the connecting head is provided with multiple rotary positioning grooves, and the other end is provided with rotary positioning projections; along with rotation of the adjusting piece, the rotary positioning projections are matched in the different rotary positioning grooves; one of the adjusting piece and the inner wall of the connecting head mounting groove is provided with a peripheral positioning groove, and the other end is provided with a peripheral positioning boss; and the peripheral positioning boss is matched in the peripheral positioning groove. The fan can adjust the the pitching angle, and has such advantages as convenience for operation, high production efficiency and high reliability.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a fan. Background technique [0002] The fans in the related art use springs and positioning beads to adjust the pitch angle of the fan. There are many parts to assemble, the assembly failure rate is high, and the production efficiency is low. The pitch angle is fixed by a fixed knob, and the user needs to Manually operate the knob to adjust, which is inconvenient to operate. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, the present invention proposes a fan, which can adjust the pitch angle and has the advantages of convenient operation, high production efficiency, and high reliability. [0004] In order to achieve the above object, a fan is proposed according to an embodiment of the present invention, and the fan includes: ...
