Description

360 degree air supply fan structure

The present invention relates to an electric fan structure, and more particularly to an electric fan structure that can blow wind power to 360 degrees at the same time.

In general, the use of electric fans is mostly to improve the convection effect in the space, so that people can stay in the fresh air and cool environment. Conventional electric fan products are mostly electric fans with a fan head and a swinging head function. The blowing direction of the fan is fixed toward the front. To increase the coverage angle of the blowing direction, the fan needs to be turned on. The oscillating function, however limited by the mechanical design, the fan head can only oscillate back and forth within a certain angle, so only users who are within this angle can feel the wind blowing, which is not conducive to most people. It is not ideal when the position is loose.

Another announcement No. M474079 has an electric fan structure with a full-circle air supply function, and an inverted cone type flow guiding cover body is arranged above the electric fan disposed on the upper side, and the flow guiding cover body has an arc wall surrounding the whole circumference. The center of the fan cover is arced upwards and outwards. According to this, the airflow of the electric fan is guided by the arc wall, and the radial flow is blown around the cover body, thereby achieving the effect of blowing the whole week. Although the structure can achieve the purpose of supplying 360 degrees to the surrounding air, the wind direction of the electric fan will be slightly depleted after the conversion process, and the wind strength is weakened. Therefore, the fan structure of the full-circle air supply should still be improved. space.

In view of this, the creator is thinking hard about the structure of the electric fan that can supply 360 degrees. After actively testing and testing, the author finally got the creation. This creative department wants to mention For a 360-degree air supply fan structure, the wind formed by the fan is directly radiated to the surroundings, so that the fan has the effect of supplying air all the way.

In order to achieve the above object, the technical means proposed by the present invention is to provide a 360-degree air supply fan structure, which has a centrifugal fan mounted on a fan seat, and has a supporting foot under the fan seat, surrounding the fan. An air outlet grille is arranged around the seat, and the air outlet grille is composed of a plurality of air outlet slots, and the air outlet slot is formed with a chamfer-shaped windward opening; an upper cover cover is coupled to the upper side of the air outlet grille. The upper cover has an air inlet, and the air inlet can further be provided with a filter.

According to this, the airflow generated by the operation of the centrifugal fan is directly blown outward through the airflow grille by 360 degrees.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic exploded view of a preferred embodiment of the present invention.

Figure 2 is a partial cross-sectional view showing the structure of a preferred embodiment of the present invention.

Figure 3 is a perspective view of the appearance of the preferred embodiment of the present invention.

Figure 4 is a schematic representation of the wind direction of the preferred embodiment of the present invention, directly from the inside to the outside.

To further clarify the structural features, functions, and other advantages of the present invention, the preferred embodiments and the drawings are described in detail below.

Referring to FIG. 1 and in conjunction with FIG. 2, the 360 degree air supply fan structure includes a centrifugal fan (10) mounted on a fan base (20) having a fan seat (20) underneath. a support foot (20), around the fan seat (20) is provided with an air outlet grille (30), the air outlet grille (30) is composed of a plurality of air outlet slots (31), The windward opening (32) of the air outlet groove (31) is formed in a chamfered shape to increase the opening area for receiving the air volume; an upper cover (40) is covered and coupled to the upper side of the air outlet grille (30), the upper cover (40) An air inlet (41) is formed, and the air inlet (41) can further be provided with a filter (42), which, in addition to increasing safety, also helps to keep the inside of the fan clean.

In the fan structure of the 360-degree air supply described above, the fan type of the present invention uses a centrifugal fan, so that when the fan is in operation, the fan can feel the wind in the radial direction all the way, which is different from the axial fan. The wind is blown in a specific direction; in addition, the wind generated by the centrifugal fan used in this creation is directly diverged 360 degrees in the direction of centrifugation. It is understandable that the wind strength of the creation is naturally uncompromised. It is necessary to cooperate with other components to change the wind direction of the fan structure. The above-mentioned filter (42) structure can be further detachable design, which is convenient for cleaning.

Please refer to Figure 3 again. After the above structure is assembled and implemented, the overall appearance can only be seen that a fan head with an air outlet grille (30) is placed on a foot (21). Fans and other components, so have a simple aesthetic and high security; when used, can be placed in the use of space, regardless of where the direction of fan blowing, it is understandable, personnel are free to be around the electric fan At one angle, the wind can be naturally felt, and the electric fan structure of the present invention can be used for 360 degree air supply.

It can be seen from the description of the above embodiments that the fan structure of the 360-degree air supply is simple and easy to produce, and the effect of full-circle air supply can be achieved without applying to a complicated swinging mechanism, and the wind generated by the blade is shown in FIG. It is the same as the direction of blowing, so the wind is directly sent out without the disadvantage of strength loss. It can be seen that this creation is indeed more effective than the conventional electric fan structure.

In summary, the 360-degree fan structure of the creation has actually reached the preset purpose, fully meets the needs of the industry, and has filed a patent application according to law. However, the above is only a preferred embodiment of the present creation. It is not intended to limit the creation of this work, and the scope of protection of this creation is subject to the definition of the scope of the patent application.
