Description

Technical Field

[0001] The utility model relates to the technical field of fan net covers, in particular to a front net cover structure of a floor fan. Background Art

[0002] The currently used floor-standing electric fans supply air by rotating the fan blades driven by the rotation of the motor. Considering the safety issue in use, a mesh cover is provided to prevent injuries caused by being hit by the fan blades. However, the existing mesh cover has a fixed gap. When the gap is large, the air flow will not be greatly blocked, but small children's fingers can be inserted into the mesh cover, which is prone to accidents. When the mesh cover gap is small, although safety is guaranteed, the air flow will be greatly blocked, thereby affecting the blowing effect and failing to meet people's use needs.

[0005] A front mesh cover structure of a floor fan includes an outer mesh cover and an inner mesh cover arranged in front and back, a fixed plate and a rotating seat are respectively provided in the center of the outer mesh cover and the inner mesh cover, the rotating seat is arranged on the inner side of the fixed plate for rotation in contact, a first rotating shaft is provided on the front side of the rotating seat, and a first knob is provided after the first rotating shaft rotates through the fixed plate, and a positioning component is also provided between the fixed plate and the rotating seat for positioning the two.

[0006] In some embodiments, the positioning assembly includes a first groove provided on one end of the rotating seat close to the fixed disk, a first spring and a first positioning steel ball are provided in the first groove, and a first positioning groove and a second positioning groove are provided along the circumference of the inner side of the fixed disk that can cooperate with the first positioning steel ball.

[0007] In some embodiments, protective lines are provided on the outer wall of the first knob.

[0008] In some embodiments, a cavity is provided in the rotating base, an aromatherapy material bag is provided in the cavity, and a through hole communicating with the cavity is provided on the outer wall of the rotating base.

[0009] In some embodiments, a second rotating shaft is coaxially mounted in the first rotating shaft, one end of the second rotating shaft extends into the cavity and is provided with a baffle, which can follow the rotation of the second rotating shaft so that the baffle can close the through hole or expose the through hole.

[0010] In some embodiments, a second knob is provided at an outer end of the second rotating shaft.
