Description

Technical Field

[0001] The utility model belongs to the technical field of electric fans, and particularly relates to an installation structure of a fan head. Background Art

[0002] As one of the commonly used household appliances in the working and family environments, electric fans, especially wall-mounted electric fans, have the characteristics of low energy consumption, small volume, and easy placement, and play a very important role in people's lives. The wall-mounted electric fans in the prior art include a fan bracket, a fan head, a fan blade, and a fan grille. The fan head is assembled on the fan bracket, the fan blade is rotatably installed on the fan head, and the fan grille is assembled on the fan head. Therefore, its structure is relatively mature technically.

[0003] Patent Document No. CN205908498U discloses a fan with an improved shaking head structure, which includes a head and a grille. A motor is fixed in the head through a motor housing, and an output shaft of the motor passes through the head and extends into the grille to be connected with a fan blade. The feature is that a wall-mounted seat is installed on the head. The wall-mounted seat consists of a connecting seat and two support rods. One ends of the two support rods are connected with the connecting seat, and the other ends are respectively rotatably connected with the upper end and the lower end of the head through an upper connecting head and a lower connecting head. Upper and lower connecting shafts respectively extend from the upper end and the lower end of the motor housing. The upper connecting shaft is rotatably connected with the upper connecting head, and the lower connecting shaft is rotatably connected with the lower connecting head. A swinging motor is also installed on the motor housing. An output shaft of the swinging motor is connected with an eccentric sleeve, and a connecting rod is connected to the eccentric sleeve. The other end of the connecting rod is connected with the head. When assembling the fan, the motor needs to be fixedly installed in the motor housing first, and then the whole head is installed on the wall-mounted seat. The problem is that for the fan with the above structure, the motor and the motor housing are not detachable separately. When assembling the fan, the whole head needs to be installed on the wall-mounted seat. Due to the large weight and large volume of the whole head, it is not convenient for people to assemble the head on the wall-mounted seat. Moreover, assembling the head requires adding installation processes and installation personnel in the assembly process, increasing the assembly time of the fan, reducing the installation efficiency of the fan, increasing the installation personnel for assembling the fan, resulting in an increase in the assembly cost of the fan, which is not conducive to the cost control of the fan by the enterprise.

[0004] Therefore, further improvement is needed. Summary of the Utility Model
