Abstract

The utility model relates to an adjustable air grate for an electric fan, belonging to the technical field of the air grate for the electric fan. The utility model is composed of a grate frame, a grate, and an adjustor. Each grate blade is surrounded at the center part of the grate and is separately positioned on the tangential directions of a circumference which uses the center of the grate and has different radii. When the electric fan lies in some gear, the adjustor which is arranged on the grate frame is rotated, each grate blade is rotated, and therefore, the dispersing and the collecting of the space scale of the airflow of the electric fan can be adjusted, and the purpose of the weakening or the reinforcing of the airflow can be achieved. The utility model has the advantages of artful design, novel structure, and good effect. Besides, the utility model can become the substitute of the traditional air grate.

Description

Electric fan with adjustable air grate

The utility model relates to electric fan air grid (fan cover) technical field.That existing electric fan has is fixed, head-swinging type, rotation air grid formula etc., and they are when work, and the power of its air-flow, poly-space range of loosing wind are to be regulated by the speed shelves of electric fan oneself motor.

The purpose of this utility model provides a kind of adjustable electric fan air grid, when fan motor is in a certain speed shelves operating mode, also can reach the requirement that the power that changes air-flow and the poly-space range of loosing of air-flow satisfy people.

The technical solution of the utility model is achieved in that this air grid is by the grid frame, grid leaf and regulator are formed, in the grid frame comprises, housing and connection former, each grid leaf is around grid frame center, form with grouping is distributed on the grid frame, and to be in grid frame center respectively be on the garden Zhou Fangxiang of different radii of the garden heart, regulator comprises a driving gear that is located in the grid frame inside casing, the some driven gears that have belt grooves that are distributed on the driving gear and are meshed with it, be located on the grid frame housing some belt pulleys and on driven gear and belt pulley and the chape that links to each other with each grid leaf, be parallel to each other between each grid leaf on the same group, rotate this regulator, synchronous rotation can take place in each grid leaf.

Adopt said structure, can accomplish: regulate on the basis of air-flow power with class at existing electric fan, the power of further regulating air-flow more fully satisfies the demand of user to the air-flow power; Can regulate as required, make air-flow diffusion, make people in space more widely wind-engaging simultaneously, overcome existing shake the head electric fan and rotation air grid electric fan and wanted certain hour at interval air-flow could be blown to the shortcoming of the same space position; And operate very convenient, need only along or rotate counterclockwise handle and just can achieve the goal.

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is the utility model surface structure front elevational schematic;

Fig. 2 is in structural representation in the inside casing for the utility model regulator;

Fig. 3 concerns schematic representation (double dot dash line is the imagination signal of handle, inside casing and former) for master, driven gear engagement and the position of the utility model regulator;

Fig. 4 drives the schematic representation of grid leaf rotation on the same group for the utility model belt;

Fig. 5 is the utility model grid leaf and grid frame former connecting relation schematic representation.

As Fig. 1, Fig. 2 and shown in Figure 3, air grid is made up of grid frame, grid leaf, regulator.The grid frame is the circular former 3 that comprises grid frame housing 1, inside casing 2, connection internal and external frames, each grid leaf 4 is divided into six groups around grid frame center and is distributed on the grid frame, and to be in grid frame center be garden week of each different radii of the garden heart on the tangent direction, and regulator includes: be in grid frame inside casing 2 hollow cavities active spiral gear 5, thereon uniform and six passive spiral gears 6 that have belt grooves of being meshed with it, be arranged on corresponding six belt pulleys 7 on the grid frame housing 1 and be enclosed within corresponding six roots of sensation chape 8 on passive spiral gear 6 and the belt pulley 7.As Fig. 4, Fig. 5, the two edges mid point of rectangular laminar grid leaf links to each other with chape, and the two ends spindle nose 10 of grid leaf is embedded in respectively in the groove of two adjacent formers 3, and Spielpassung with it, and the grid leaf is parallel to each other on the same group.When rotating the handle 9 that is connected mutually with active spiral gear 5, initiatively spiral gear drives corresponding passive spiral gear rotation, drives corresponding chape then and rotates, thereby make each grid leaf that synchronous the rotation be taken place.So just can reach the power and the scope poly-, the space of loosing that change air-flow.
