Above-mentioned guide plate is made up of the right angle fixed plate that four pieces are provided with an arc-shaped side edges and two straight shape sides, and the arc-shaped side edges of described four pieces of right angle fixed plates forms the circular air-guiding hole of guide plate.
Above-mentioned arc-shaped side edges is made up of the arc plate be located on right angle fixed plate one side.
Above-mentioned guide plate is gone up inside the shell by straight shape side is fixing.
Above-mentioned straight shape side is provided with and is fixedly connected with block, and described guide plate is fixed on shell by being fixedly connected with block.
Above-mentioned circular air-guiding hole is greater than the rotation external diameter 20-50mm of blower fan rotor blade.
Above-mentioned right angle fixed plate, arc-shaped side edges are integral type structure with being fixedly connected with block, the right angle fixed plate of this integral structure, arc-shaped side edges be fixedly connected with block by the disposable injection-compression molding of glass fibre reinforced plastic material.
The beneficial effects of the utility model:
1, be provided with the guide plate being with circular air-guiding hole in shell of the present utility model, this guide plate is located at inside outer cover body, is positioned at the outside of the rotation external diameter of blower fan rotor blade; The size of described air-guiding hole is corresponding with the rotation diameter of blower fan rotor blade, and blower fan rotor blade is rotated in air-guiding hole.Thus, the rotor blade that blower fan is driven can rotate in circular air-guiding hole, makes blade effectively can draw exogenous wind and sends into indoor, so effectively improve blower fan change wind efficiency.
2, guide plate of the present utility model is made up of the right angle fixed plate that four pieces are provided with an arc-shaped side edges and two straight shape sides, and the arc-shaped side edges of described four pieces of right angle fixed plates forms the circular air-guiding hole of guide plate, make its structure simple, simplify and produce.
3, arc-shaped side edges of the present utility model is made up of the arc plate be arranged on right angle type fixed plate one side, when can effectively avoid blower fan to drive blower fan rotor blade to rotate thus, and generation backflow in housing of blowing, and then effectively improve air-supply effect.
4, right angle of the present utility model fixed plate, arc-shaped side edges and to be fixedly connected with block be integral type structure, the right angle fixed plate of this integral structure, arc-shaped side edges be fixedly connected with block by the disposable injection-compression molding of glass fibre reinforced plastic material, effectively can improve the efficiency of production thus, reduce cost of production, improve guide plate, arc-shaped side edges simultaneously and be fixedly connected with block acid-fast alkali-proof strong, use can not produce fracture, uses the working life that all effectively can extend blower fan in any environment.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
There is the Blower Housing of good wind-guiding function as shown in Figure 1 to Figure 3, include shell 1, the square casing that this shell is combined by four blocks of side plates 11, the guide plate 3 being with circular air-guiding hole 2 is provided with in described shell 1, this guide plate 3 is located at inside shell 1, is positioned at the outside that blower fan rotor blade 4 rotates external diameter; It is corresponding that size and the blower fan rotor blade 4 of described circular air-guiding hole 2 rotate diameter, and blower fan rotor blade 4 is rotated in circular air-guiding hole 2.
In concrete enforcement, described circular air-guiding hole 2 is greater than the rotation external diameter 20-50mm of blower fan rotor blade 4.Described guide plate 3 is made up of the right angle fixed plate 31 that four pieces are provided with an arc-shaped side edges 32 and two straight shape sides 33, and the arc-shaped side edges 32 of described four pieces of right angle fixed plates 31 forms the circular air-guiding hole 2 of guide plate 3, forms air-guiding aisle.Concrete, be located at contiguous block 311 respectively at fixed plate 31 two ends, every block right angle, when two pieces of right angle fixed plates 31 are installed, adjacent right angle fixed plate 31 one end is interconnected and fixed by corresponding contiguous block 311, forms the guide plate 3 of the circular air-guiding hole 2 of band.This arc-shaped side edges 32 is made up of the arc plate be located on right angle fixed plate 31 1 side.Guide plate 3 is fixed on inside shell 1 by straight shape side 33.
Better be fixed on shell 1 to make right angle fixed plate 31, described straight shape side 33 is provided with and is fixedly connected with block 34, described guide plate 3 is fixed on shell 1 by being fixedly connected with block 34, concrete, guide plate 3 is by adopting the mode such as blind rivet or rivet to be fixed being fixedly connected with on block 34 and shell 1.Simultaneously, in order to better boost productivity and extend working life of product, described right angle fixed plate 31, arc-shaped side edges 32 be fixedly connected with block 34 for integral type structure, the right angle fixed plate 31 of this integral structure, arc-shaped side edges 43 be fixedly connected with block 34 by the disposable injection-compression molding of glass fibre reinforced plastic material.Same, four pieces of described right angle fixed plates 31 also can adopt the disposable injection-compression molding of one set of die, namely whole guide plate 3 can adopt the disposable injection-compression molding of one set of die, makes four pieces of right angle fixed plates 31 form integral structure, but the cost of the mould of the increase designing and making needed.
