Abstract

The invention discloses an electric fan. The electric fan comprises a fan head assembly, an adjusting box and a fan body assembly. The fan head assembly is arranged on the adjusting box. The adjusting box is arranged on the fan body assembly in the mode of rotating around a horizontal rotating shaft. The horizontal rotating shaft is sleeved with an adjusting gear in a sliding mode. The adjusting gear is fixed to the fan body assembly in the circumferential direction. The first end face of the adjusting gear is provided with first end face teeth extending towards the adjusting box. The adjusting box is provided with second end face teeth matched with the first end face teeth. An adjusting spring is arranged between the second end face of the adjusting gear and the fan body assembly. One end of the adjusting spring abuts against the first end face of the adjusting gear. The second end of the adjusting spring abuts against the fan body assembly. According to the electric fan, the problems that due to frictional wear, frictional force between the adjusting box and the fan body assembly is reduced, and the fan head assembly droops can be effectively prevented.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an electric fan. Background technique [0002] The main body of electric fans currently on the market is as attached figure 1 As shown, the head assembly 1 and the adjustment box 2 are connected in a limited position by screws 3, the head assembly 1 and the fuselage assembly 9 are assembled mainly through the adjustment box 2, the balance spring 4, the positioning piece 5 and the adjustment spring assembly 6, and then through The nut 7 and the bolt 8 are assembled and fixed to realize the adjustment of the up / down shaking head angle, and finally achieve the user's ideal air supply angle. [0003] One end of the two mounting feet of the balance spring 4 is assembled with the adjustment box 2, and the other end is staggered with a certain angle along the circumferential direction with the locking slot of the fuselage assembly 9, so as to ensure that sufficient torque can be ge...
