Problems solved by technology

[0003] The disadvantages of this structure are: 1. To press the straight buckle into the card hole, you need to slightly open the edge of the card hole with one hand, and press the buckle with the other hand, which makes assembly difficult, low work efficiency, and the broken card hole There will be a certain deformation, which will make it difficult for the buckle-card hole to fit together; 2. The clamping force between the straight buckle and the card hole is insufficient, and it is easy to fall off under external vibration, and the stability is not strong

Embodiment 1

[0031] The preferred embodiment discloses an electric fan head assembly, which includes a casing, a motor arranged in the casing, and a cover covering the opening end of the casing. There are card holes on the cover, such as Figure 1 to Figure 3 As shown, the cover 1 is provided with a U-shaped buckle 2 matching the card hole.

[0032] The U-shaped buckle 2 has a certain elastic deformation ability, the clamping force between the clamping hole and the clamping hole is stronger, and the fit is more stable. It is convenient, and the U-shaped buckle 2 can be pressed into the card hole with only one hand, and the work efficiency is high and the cost is low.

[0033] The number and position of the U-shaped buckles 2 provided on the cover 1 are not limited. In order to enhance the connection stability between the case and the cover, preferably, at least four U-shaped buckles 2 are arranged symmetrically on the center of the cover 1 .

[0034] The specific structure of the U-shap...

Embodiment 2

[0042] This preferred embodiment discloses an electric fan, including a bracket and various electric fan head assemblies in the first preferred embodiment.

Abstract

The invention discloses an electric fan machine head assembly and an electric fan and belongs to the field of electric fans and accessories of the electric fans. The electric fan machine head assembly and the electric fan are designed for solving the problems that an existing structure is low in assembling efficiency and the like. The electric fan machine head assembly comprises a case, a motor arranged in the case and a cover covering the opening end of the case. Clamping holes are formed in the case and U-shaped buckles matched with the clamping holes are arranged on the cover. The electric fan comprises the electric fan machine head assembly. When the electric fan machine head assembly is assembled, the guidance performance of the U-shaped buckles is used so that a worker can finish buckling work with one hand, and assembling efficiency is high; the U-shaped buckles have the elastic extruding effect, the case and the cover are not likely to fall after being assembled, and stability is high; and the assembling structure of the case and the cover of the electric fan is more stable, the service life is long, and noise is low.

Description

technical field [0001] The invention relates to the field of electric fans and accessories thereof, in particular to an electric fan head assembly and an electric fan including the head assembly. Background technique [0002] The electric fan head assembly usually includes a casing, a motor and a cover, the motor is placed in the casing, and the cover is covered at the open end of the casing. In order to simplify the installation process, usually a straight buckle is provided on the cover, and a clamping hole is provided on the cover, and the cover is covered on the cover after the buckle is pressed into the clamping hole. [0003] The disadvantages of this structure are: 1. To press the straight buckle into the card hole, you need to slightly open the edge of the card hole with one hand, and press the buckle with the other hand, which makes assembly difficult, low work efficiency, and the broken card hole There will be a certain deformation, which will make it difficult fo...
