Abstract
The present utility model provides an air fan, comprising: a main propeller (19); a main motor (24) operably connected to the main propeller (19), driving the main propeller (19) to rotate to generate air stream; characterized in that the air fan further comprises a wind guide device composed of a wind guard plate (35) and a wind reject plate (21) and surrounding the main propeller (19), a gap is provided between the wind guard plate (35) and the wind reject plate (21) for facilitating flowing out of air; an auxiliary motor (53) operably connected to the wind guide device via a rotation-oscillation shifting device, for driving the wind guide device to oscillate to change the wind direction.
Description
- The present utility model relates to an air fan, comprising a main propeller and a main motor operably connected to the main propeller, the main motor driving the main propeller to rotate to generate air stream.
- The prior art discloses various fans such as ground fans, table fans, ceiling fans, vane rotating fans, and transverse flow type fans, some examples of which can be seen in the patent documents U.S. Pat. No. 6,344,065B1, CN1063530C, CN1034043A and CN1147603A or in FS29-SW tower fan as shown in
FIG. 4 . These conventional air fans have the following drawbacks: - 1) As for conventional ground fans, table fans, ceiling fans and transverse flow type fans, wind direction is changed by allowing the whole fan head and the whole substantially cylindrical housing to oscillate. In this circumstance, the whole fan head and the whole substantially cylindrical housing are large in mass so the rotation inertia is relatively great, so more energy is consumed to change wind direction. With respect to the conventional vane rotating fans, the guide vanes in the front face are rotated to change wind direction. Under this circumstance, the radius of the guide vanes are relatively large so that the rotation inertia is relatively great, so more energy is consumed to change wind direction. In addition, the conventional fans with oscillating heads require a predetermined indoor space for oscillation of the fan head, which is particularly disadvantageous in a narrow environment. To sum up, one defect of the fans in the prior art is a greater consumption of energy and a larger occupation of space.
- 2) As the oscillating part (the whole fan head and the whole substantially cylindrical housing) or rotating part (guide vanes) for changing wind direction are exposed to the outside in the prior art, oscillation or rotation might injure by accident the ambient objects or human beings such as an operator, for example, when the juveniles operate the air fan, the oscillating head, housing or rotating vanes might injure his fingers by accident. In summary, another defect of fans in the prior art is a certain danger in operation.
- 3) in addition, the conventional fan with oscillating head, in operation, may shift its center of gravity due to oscillation of the head. Therefore, another defect of fans in the prior art is that the fan in operation is not stable and steady enough and is liable to overturn.
- In order to overcome the defects in the prior art, the present utility model provides an air fan adopting an internal oscillation technology, comprising: a main propeller and a main motor operably connected to the main propeller, the main motor driving the main propeller to rotate to generate air stream, characterized in that the air fan further comprises a wind guide device composed of a wind guard plate and a wind reject plate and surrounding the main propeller, a gap is provided between the wind guard plate and the wind reject plate for facilitating flowing out of air; an auxiliary motor operably connected to the wind guide device via a rotation-oscillation shifting device, for driving the wind guide device to oscillate to change the wind direction.
- In a preferred technical solution, the air fan further comprises an ion generator.
- In another preferred technical solution, the air fan further comprises a water filter.
- In a further preferred technical solution, the air fan further comprises an enclosure in which the main propeller and the wind guide device are both disposed.
- In a further preferred technical solution, the rotation-oscillation shifting device is a crank and rocker mechanism.
- As compared with the prior art, the present utility model is advantageous in the following points: 1) the rotation inertia of the oscillating member (i.e., the wind guard plate and the wind reject plate) is smaller, so the air fan according to the present utility model is energy saving; besides, no space needs to be reserved to facilitate oscillation of head of the air fan, which is particularly advantageous in a narrow environment; 2) the enclosure is stationary and encloses the oscillating wind guide device so that the air fan is pretty much safer; 3) the internal oscillation technology allows the center of gravity of the whole air fan to be stable and steady so that the center of gravity is not shifted any more as in the conventional fans due to oscillation of head. As a result, the air fan according to the present utility model is extremely stable and is not liable to overturn.
