Abstract

A mounting structure for the dissipating wind surface is provided. The mounting structure comprises: a cross-shaped plate (1) fixed to the front surface (2) of the box fan body by screw (3), the dissipating wind surface (4) provided with bearings (5), the cross-shaped plate (1) impaled by a bolt (6) with a threaded part (6.1) at the end, the bolt (6) fitted with speed adjusting cap (7), a round gasket (8) with the cut of hexagon form mounted to block in front of the disipating wind surface (4), the round gasket which is engaged in the corresponding hecxagon part (11) in the cross-shaped plate (1), oil soaked felt ring (9) that is mounted between the disipating wind surface (4) and the round gasket (8), a spring (10) that is inserted into the cylinder (7.1) mounted on the inside of the speed adjusting cap (7).

Description

The mounting structure that is used for the diffusing wind face of box electric fan
Technical field
The present invention program relates to the mounting structure of the diffusing wind face that is used for box electric fan (box electric fans).
Background technique
At present, most commercially available box electric fans use the wind system that looses that wind is loose towards periphery.The principle of this system is that main blade is installed on the main motor.When motor moved, main blade was collected wind and wind is gone ahead and blows.For wind is loose towards periphery, a kind of diffusing wind face is attached to fan body and is placed on the main blade front.The wind face that looses receives wind from main blade and rotates around the axis of main blade simultaneously.For controlled wind speed, provide the regulating mechanism of the combination of cylindrical or conical and these shapes.Yet, find these diffusing wind faces because there is noise in friction, unstable properties, and need lot of materials in the mill.
In addition, these diffusing wind faces must be adjusted and make them change also soon than main blade, and this will cause the electric fan vibrations of jolting.In order to overcome these influences, regulating device should be fastening by the user, but this is also inconvenient.In addition, if motor speed reduces, turns off and restarts under low wind speed pattern, the wind face that looses can be difficult to rotate.In above-mentioned situation, the user should become flexible (unfasten) velocity adjustment apparatus.
Summary of the invention
The invention provides a kind of mounting structure that is used for the diffusing wind face of box electric fan, this structure plays the effect of offsetting and overcoming above-mentioned shortcoming.
In order to realize this purpose, the mounting structure that is used for diffusing wind face according to the present invention comprises: a cross plate, by the front surface of screw fixings in box fan body; The wind face that looses is furnished with adaptive bearing; The bolt that end has the screw section passes described cross plate, and described bolt is furnished with speed and adjusts cap; Rounded washers with Hexagon otch is mounted retaining face in face of described diffusing wind.This rounded washers engages corresponding hexagonal part in the described cross plate; Oil immersion felt ring (collar (oil soaked felt ring) is loaded between described diffusing wind face and the described rounded washers; A spring inserts in the cylinder that is installed in described speed adjustment cap inboard.
Description of drawings
Fig. 1 is the three-dimensional exploded view of mounting structure that is used for the diffusing wind face of box electric fan, and described mounting structure prepares to be mounted to fan body;
Fig. 2 is the three-dimensional exploded view of mounting structure that is used for the diffusing wind face of box electric fan, and described mounting structure prepares to be mounted to fan body;
Fig. 3 is the sectional arrangement drawing of mounting structure that is used for the diffusing wind face of box electric fan, and described mounting structure has been mounted to fan body.
Embodiment
According to Fig. 1, Fig. 2 and Fig. 3, comprise according to the mounting structure of the wind face that is used for loosing according to the present invention: a cross plate 1, be fixed in the front surface 2 of box fan body by screw 3; Diffusing wind face 4 is furnished with adaptive bearing 5; The bolt 6 that end has screw section 6.1 passes described cross plate 1; Bolt 6 is furnished with speed and adjusts cap 7; Rounded washers 8 with Hexagon otch is mounted retaining in diffusing wind face 4 fronts.11, one oil immersion felt ring (collars 9 of corresponding hexagonal part that this rounded washers engages in the cross plate 1 are installed between diffusing wind face 4 and the rounded washers 8, and a spring 10 is inserted in the cylinder 7.1, and this cylinder 7.1 is installed in the inboard that speed is adjusted cap 7.
According to Fig. 3, when the speed that clockwise rotates is adjusted cap 7, spring 10 will promote rounded washers 8 and prop up the wind face 4 that looses, and this increases the frictional force of loosing between wind face 4 and the rounded washers 8, cause the rotating speed of the wind face 4 that looses to reduce.On the contrary, when speed is adjusted cap 7 then rotated counterclockwise, spring will stretch upwards, and make rounded washers 8 no longer prop up the wind face 4 that looses.At this moment, the frictional force of loosing between wind face 4 and the rounded washers 8 reduces, and causes the wind face 4 that looses according to the faster rotation of the speed of main blade.Because the accuracy of bearing 5 and the elasticity of spring 10 make diffusing wind face 4 keep necessary balance, this makes fan itself no longer rock.
