Description

Technical Field

[0001] The utility model belongs to the technical field of table fans, and particularly relates to a wind-dispersing fan cover for a table fan. Background Art

[0002] During the market research of electric fans by the applicant, it was learned that in hot seasons, some users have the habit of using table fans to blow continuously for a long time. Generally speaking, it is also unfavorable to the user's body for a table fan to blow continuously towards the user or a certain part of the user's body (such as the head, etc.) for a long time. For this reason, most of the existing table fans are equipped with a steering device. Through the steering device, the table fan can shake its head regularly to avoid blowing continuously towards a certain part of the user's body for a long time, which is relatively beneficial to the user's body. However, some users still reported to the applicant that when using a table fan to blow, they hope that all parts of their bodies can be blown continuously for a long time, but at the same time, they also hope that the airflow generated by the table fan is relatively gentle. However, the existing table fans are difficult to meet their requirements. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the airflow generated by the table fan is relatively gentle and can enable all parts of the user's body to be blown continuously for a long time, thereby overcoming the above-mentioned defects of the prior art. This purpose is achieved through the following technical solutions:

[0004] A wind-dispersing fan cover for a table fan includes a front cover body and a rear cover body. The front cover body and the rear cover body are fixedly connected in a detachable manner. The front cover body includes an annular frame and a middle circular plate. The middle circular plate is connected to the annular frame through two horizontally symmetric transverse support bars and two vertically symmetric longitudinal support bars. Taking the middle circular plate as the center, the two horizontally symmetric transverse support bars and the two vertically symmetric longitudinal support bars divide the front cover body into four functional areas: upper left, upper right, lower left, and lower right. In each functional area, there are multiple arc-shaped grid plates. The two ends of each arc-shaped grid plate are respectively connected to the transverse support bar and the longitudinal support bar. The space between adjacent arc-shaped grid plates forms an air flow channel. In the upper left functional area, each arc-shaped grid plate is inclined towards the upper left. In the upper right functional area, each arc-shaped grid plate is inclined towards the upper right. In the lower left functional area, each arc-shaped grid plate is inclined towards the lower left. In the lower right functional area, each arc-shaped grid plate is inclined towards the lower right.

[0005] Further, the front cover body is integrally formed.

[0006] Furthermore, four arc-shaped grille plates are provided in each functional area. The four arc-shaped grille plates in the upper left functional area are all inclined at 45 degrees to the upper left, the four arc-shaped grille plates in the upper right functional area are all inclined at 45 degrees to the upper right, the four arc-shaped grille plates in the lower left functional area are all inclined at 45 degrees to the lower left, and the four arc-shaped grille plates in the lower right functional area are all inclined at 45 degrees to the lower right.

[0007] Compared with the prior art, the present utility model has the following beneficial effects:

[0008] Through the blockage of the arc-shaped grille plates and the air flow channels in different directions formed between the adjacent arc-shaped grille plates in each functional area, the present utility model can make the table fan matched with it have a good effect of dispersing the fan air flow, thereby solving the technical problems that some users hope that all parts of the body can be continuously blown for a long time and the air flow generated by the table fan is relatively gentle. It should be noted that although the blockage of the arc-shaped grille plates will consume a part of the electric energy, since the table fan does not need to shake its head (which also consumes electric energy), the present utility model can generally reduce the energy consumption and simplify the structure of the table fan (omitting the steering device).

[0017] In order to more fully illustrate the technical solution of the present utility model, the following introduces an embodiment of the present utility model with reference to the accompanying drawings.

[0018] As Figure 1 , Figure 2 , Figure 3As shown, a wind-dispersing fan cover of a table fan includes a front cover body 1 and a rear cover body 2, and the front cover body 1 and the rear cover body 2 are fixedly connected in a detachable manner (for example, through screw holes and screws). The front cover body 1 includes an annular frame 11 and a middle circular plate 12. The middle circular plate 12 is connected to the annular frame 11 through two horizontally symmetric transverse support bars 13 and two vertically symmetric longitudinal support bars 14 (the so-called symmetry is with respect to the center of the middle circular plate). Centered on the middle circular plate, the two horizontally symmetric transverse support bars 13 and the two vertically symmetric longitudinal support bars 14 divide the front cover body into four functional areas: upper left, upper right, lower left, and lower right (the so-called upper left, upper right, lower left, and lower right are based on Figure 1 what is shown). In each functional area, there are multiple arc-shaped grid plates (the specific number of arc-shaped grid plates can be adjusted according to the specific size of the supporting table fan). The two ends of each arc-shaped grid plate are respectively connected to the transverse support bar and the longitudinal support bar. The space between adjacent arc-shaped grid plates forms an air flow channel. In the upper left functional area, each arc-shaped grid plate slopes upward to the left (the corresponding air flow channel slopes upward to the left). In the upper right functional area, each arc-shaped grid plate slopes upward to the right (the corresponding air flow channel slopes upward to the right). In the lower left functional area, each arc-shaped grid plate slopes downward to the left (the corresponding air flow channel slopes downward to the left). In the lower right functional area, each arc-shaped grid plate slopes downward to the right (the corresponding air flow channel slopes downward to the right).

[0019] In this embodiment, the front cover body is integrally formed. That is, during the production process, the annular frame 11, the middle circular plate 12, the two transverse support bars 13 and the two longitudinal support bars 14 are integrally formed using a mold, and the connection between each part is a seamless connection. Additionally, in this embodiment, each functional area is provided with 4 arc-shaped grid plates. The 4 arc-shaped grid plates in the upper left functional area all slope upward to the left by 45 degrees. The 4 arc-shaped grid plates in the upper right functional area all slope upward to the right by 45 degrees. The 4 arc-shaped grid plates in the lower left functional area all slope downward to the left by 45 degrees. The 4 arc-shaped grid plates in the lower right functional area all slope downward to the right by 45 degrees.
