Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1 and 2, the air circulation device according to the present invention includes a support frame 1, which is configured with a plurality of rod bodies and plate bodies to form a stable structure for fixing a fan motor 2. The top end of the support frame 1 is provided with a top plate 11, and the top plate 11 can be locked on the ceiling 7 by using fixing elements such as screws, so that the support frame 1 can be fixedly arranged.
Accordingly, the fan motor 2 extends downward to form a transmission shaft 21 and is connected to a fan 3, so that the fan 3 can be driven to rotate and generate an air flow. The transmission shaft 21 is further connected to a wind guiding plate 4 downward after passing through the fan 3, wherein the wind guiding plate 4 has a wind guiding surface 41 facing the fan 3, and is formed in an arc shape and has an area larger than that of the fan 3. In the present embodiment, a lamp 42 may be further disposed at the bottom of the air guiding plate 4 to increase functionality and decoration.
The fan 3 and the air guiding plate 4 are further provided with a cover body 5, the upper end of the cover body is provided with a straight cylinder part 51 covering the support frame 1 and the fan 3, the cover body is provided with a plurality of fence-shaped air suction openings 511 which are arranged at intervals, the lower end of the cover body is provided with an expanded skirt part 52, and the skirt part 52 extends to the periphery of the air guiding plate 4 and covers the upper part of the air guiding plate 4. An air guiding space 43 is formed between the skirt portion 52 and the air guiding surface 41, and an annular air outlet 44 is formed in a gap between the peripheral edge of the skirt portion 52 and the peripheral edge of the air guiding plate 4. When the fan 3 rotates, the air current that is rolled enters the cover 5 from the air suction opening 511, passes through the fan 3, is blocked by the air guiding disc 4 downwards, flows laterally along the air guiding surface 41 in the air guiding space 43, and is then discharged from the air outlet 44.
In this embodiment, the air guiding surface 41 of the air guiding plate 4 is provided with a plurality of guiding blocks 45, and each guiding block 45 extends outward from the center of the air guiding surface 41 in an arc shape. Accordingly, the airflow flowing on the air guide surface 41 forms a whirling cyclone according to the shape of each guide block 45, and the speed of the airflow output from the air outlet 44 can be increased.
Furthermore, a control motor 6 is further fixed on the support frame 1 above the fan motor 2, and is provided with an upwardly extending driving shaft 61, wherein the driving shaft 61 has a threaded section 62; on the other hand, a rib 512 is disposed in the straight body portion 51 of the cover body 5 in a transverse direction, the rib 512 has a screw hole 513, and the driving shaft 61 is screwed into the screw hole 513.
In the above structure, since the control motor 6, the fan motor 2 and the support frame 1 are fixed to the ceiling 7, when the control motor 6 drives the driving shaft 61 to rotate, the ribs 512 will generate relative vertical displacement by the spiral action, thereby driving the cover 5 to move synchronously. The cover 5 is moved relative to the air guide plate 4 to change the area and direction of the air outlet 44 by the position of the skirt 52; in detail, as shown in fig. 2, when the air guiding plate 4 is closer to the skirt portion 52, the area of the air outlet 44 is smaller, and the air outlet direction is downward, and when the skirt portion 52 is far away from the air guiding plate 4, as shown in fig. 3, the area of the air outlet 44 is larger, and the air outlet direction is changed into a lateral direction. Accordingly, the control motor 6 can be operated to move the cover 5, so as to change the area and direction of the air outlet 44, further adjust the air outlet amount and the air outlet direction, and improve the blowing range.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
