Abstract

The invention provides a fan. The fan comprises a fan head and a body housing; the fan head is connected with the body housing through a regulating box; a stopping portion is arranged on the body housing; a limiting portion matched with the stopping portion for stopping is arranged on the regulating box so as to weaken or counteract a counter acting force of a torsional spring and / or a positioning spring of the fan on the regulating box. The fan of the present invention is used for solving the problem of great assembly difficulty of a fan in the prior art.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a fan. Background technique [0002] At present, the adjustment of the pitch angle of the traditional fan head is realized by the torsion spring at the joint of the head, and the positioning is realized by the positioning spring of the fuselage. During installation, it is necessary to manually overcome the reaction force of the torsion spring and the positioning spring to align the adjustment box with the bolt holes of the fuselage shell before fastening with bolts and nuts. [0003] Therefore, it is difficult to assemble the fan in the prior art, which leads to low production efficiency of the fan. Contents of the invention [0004] The main purpose of the present invention is to provide a fan to solve the problem that the fan in the prior art is difficult to assemble. [0005] In order to achieve the above object, the present invention provides a fan, which includes a fa...
