Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, fig. 2 and fig. 3, the cyclone fan includes a body 20, an impeller 40 and a motor 10, wherein the body 20 is provided with an air cavity 21, and one end of the air cavity 21 is provided with an air inlet; the other end of the air cavity 21 is provided with an air outlet; the impeller 40 is pivoted to the air inlet; the motor 10 is installed on the machine body 20, and a rotating shaft of the motor 10 is synchronously connected with the impeller 40; the impeller 40 is provided with a plurality of blades 41, and the blades 41 extend spirally along the length direction thereof; a plurality of vanes 41 are spaced about the central axis of the impeller 40.

On the basis of the structure, when the cyclone fan of the utility model is used, the motor 10 can drive the impeller 40 to rotate, and the impeller 40 can rotate to enable the air to move along the spiral direction of the blade 41 to form a cyclone, so that the air moving along the spiral direction also rotates along the spiral direction, and the air can flow at high speed by one-time rotation of the impeller 40, thus improving the wind speed and leading the working efficiency of the fan to be higher; the power of the motor 10 does not need to be increased, and the energy consumption is reduced.

It should be noted that the impeller 40 may be pivotally connected in the air cavity 21 through a rotating shaft, and the rotating shaft may be connected to a rotating shaft of the motor 10 through a coupling in the prior art, so that the rotating structure is stable.

Furthermore, a flow guide surface can be arranged on the inner wall of the air cavity 21 and extends spirally along the air outlet direction, so that the swirling air led out by the blades 41 of the impeller 40 can move along the spiral extending direction of the flow guide surface to form swirling flow again, and the air speed is further improved.

More specifically, the inner wall of the air cavity 21 is gradually reduced from the end close to the air inlet to the end far away from the air outlet, so that the inner diameter of the air speed is reduced from the inlet to the outlet, the air pressure is increased, and the air speed at the air outlet is larger.

Preferably, the air outlet intercommunication has a tuber pipe 30, for the convenience of connecting, can with tuber pipe 30 with indoor or treat the equipment of air inlet communicate can, the tuber pipe 30 can be the welding in the air outlet department of organism 20, also can be through the air outlet department of screw assembly at organism 20.

Preferably, a sound absorbing material layer may be further provided on the inner wall of the air chamber 21, and the sound absorbing material layer may absorb sound during operation of the fan to reduce noise.

Further, can be equipped with a plurality of filling holes 21 on the inner wall of wind chamber 21, this a plurality of filling holes 21 can be around the central axis circumference interval distribution of wind chamber 21, are filled with the sound absorbing material layer in filling hole 21, and the installation on the sound absorbing material layer of being convenient for, certainly, the sound absorbing material layer can select for use the sound cotton of inhaling among the prior art to make, will inhale the sound cotton and fill to the filling hole 21 in can play the effect of inhaling the sound. Of course, the sound-absorbing cotton can also be made into a sheet structure and wrapped on the outer wall of the wind cavity 21 through screws.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
