Problems solved by technology

However, these diffuser surfaces were found to be noisy due to friction, unstable in performance, and required a large amount of material in their manufacture
[0003] In addition, these diffuser surfaces must be adjusted so that they rotate faster than the main fan blades, which will cause the fan to vibrate
To overcome these effects, the adjustment device should be tightened by the user, but this is not convenient
Also, if the motor speed is reduced, switched off and restarted in low wind speed mode, the diffuser surface will be difficult to rotate

Embodiment Construction

[0009] according to figure 1 , figure 2 with image 3 , according to the present invention, the mounting structure for the air diffuser surface includes: a cross-shaped plate 1, which is fixed to the front surface 2 of the box fan body by screws 3; the air diffuser surface 4 is equipped with an adapted bearing 5; an end A bolt 6 with a threaded portion 6.1 passes through said cross-shaped plate 1; the bolt 6 is fitted with a speed adjustment cap 7; This circular washer engages the corresponding hexagonal part 11 in the cross-shaped plate 1, an oil-impregnated felt ring 9 is mounted between the diffuser surface 4 and the circular washer 8, a spring 10 is inserted in the cylinder 7.1, This cylinder 7.1 is installed inside the speed adjustment cap 7.

[0010] according to image 3 , when the speed adjustment cap 7 is turned clockwise, the spring 10 will push the circular washer 8 against the air diffuser surface 4, which increases the friction between the air diffuser surfac...

Description

technical field [0001] The solution of the present invention relates to an installation structure for a diffuser surface in a box electric fan (box electric fans). Background technique [0002] Currently, most commercially available box fans use a diffuser system to disperse the wind to the surroundings. The principle of this system is to install the main fan blades on the main motor. When the motor is running, the main blades collect the wind and blow it straight forward. In order to disperse the wind to the surroundings, a kind of dispersing surface is attached to the fan body and placed in front of the main fan blades. The wind spreading surface receives wind from the main wind blade and rotates around the axis of the main wind blade. In order to control the wind speed, adjustment mechanisms of cylindrical or conical shape and combinations of these shapes are provided. However, these diffuser surfaces were found to be noisy due to friction, unstable in performance, an...
