Description
Technical Field
The utility model relates to a diffuser based on air-blower.
Background
The air-blower is a commonly used pressure boost air supply oxygenation mode, and the bigger the motor power of drive air-blower, the higher is the wind pressure of air supply and the flow of air supply, but also has this drawback simultaneously: firstly, the higher the power of the blower is, the higher the working noise is; and secondly, the higher the power of the blower is, the higher the energy efficiency consumption is. Therefore, although a sufficient selection is often adopted when selecting a blower, it is difficult to solve the problem by replacing the blower even when the wind pressure and the flow rate of the blown air are insufficient in practical use.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a diffuser based on an air blower, wherein the left and right connecting ends of an inner air duct of a tubular inner air duct are respectively provided with a first hollow supporting plate and a second hollow supporting plate, both ends of the inner air duct are provided with flanges, both sides of the outer circumference of the inner air duct are provided with a plurality of outwards extending supporting connecting strips, the other ends of the supporting connecting strips are fixed with the inner wall of a diffusion air duct in a cone, the inner air duct and the cone form a fixed whole, both sides of the outer circumference of the cone are evenly provided with a plurality of connecting blocks, both sides of the lower end are provided with brackets, the air inlet at the right end of the cone is a big end, the air outlet at the left end is a small end, the air inlet space volume at the right end of the diffusion air duct is larger than the air outlet at the left end, and the air outlet at the left end of a space volume component at the right end of the diffusion air duct is reduced, the, the pressure and the wind speed of the air blower can be further increased, and the practical efficiency of the air blower is improved.
In order to achieve the above purpose, the technical scheme of the utility model is that: a fan capable of forming an oblique air duct comprises a fan shell, an inner air duct, a first hollow supporting plate and a second hollow supporting plate are respectively arranged at the left connecting end and the right connecting end of the inner air duct of the tubular inner air duct, a first inner flange is arranged at the left end of the inner air duct, and a second inner flange is arranged at the left side of the second supporting plate;
a plurality of outwards extending supporting connecting strips are symmetrically and uniformly distributed at two sides of the outer circumference of the inner air duct, and the other ends of the supporting connecting strips are fixed with the inner wall of the diffusion air duct in the conical duct to form a fixed whole body of the inner air duct and the conical duct;
a plurality of connecting blocks are uniformly distributed at two sides of the outer circumference of the conical cylinder, and the connecting blocks are provided with through connecting holes;
brackets are arranged on two sides of the lower end of the conical cylinder;
the air inlet at the right end of the conical cylinder is a large end, and the air outlet at the left end of the conical cylinder is a small end.
The space volume of the air inlet at the right end of the diffusion air duct is larger than that of the air outlet at the left end, and the space volume component at the right end of the diffusion air duct is reduced towards the air outlet at the left end.
The utility model has the advantages that: the utility model discloses establish two wind channels, interior wind channel is main wind channel to be equipped with the endocentric diffusion wind channel in main wind channel, can further the pressure wind speed of too big air-blower, improve the practical efficiency of air-blower.
Drawings
Fig. 1 is a schematic view of the present invention.
In the figure: the device comprises a first inner flange 1, a first support plate 2, a second support plate 3, a support connecting strip 4, a second inner flange 5, a connecting block 6, a connecting hole 61, a bracket 7, a conical cylinder 8, a diffusion air duct 9, an inner air duct 10 and an inner air duct 11.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
As shown in fig. 1, in a diffuser based on a blower, a hollow support plate I2 and a hollow support plate II 3 are respectively arranged at the left and right connecting ends of an inner air duct 10 of a tubular inner air duct 11, an inner flange I1 is arranged at the left end of the inner air duct 11, and an inner flange II 5 is arranged at the left side of the support plate II 3; a plurality of outwards extending supporting connecting strips 4 are symmetrically and uniformly distributed at two sides of the outer circumference of the inner air duct 11, and the other ends of the supporting connecting strips 4 are fixed with the inner wall of a diffusion air duct 9 in the conical tube 8 to form a fixed whole body of the inner air duct 11 and the conical tube 8; the two sides of the outer circumference of the conical cylinder 8 are evenly distributed with a plurality of connecting blocks 6, the air inlet at the right end of the conical cylinder 8 is a big end, and the air outlet at the left end of the conical cylinder 8 is a small end.
In practical application, the diffuser is installed at the air outlet end of the air blower, the air volume of the air blower is synchronously fed from the inner air duct 10 and the diffusion air duct 9, the air pressure of the straight-through inner air duct 10 is the air outlet pressure of the air blower, the air volume entering the right end of the diffusion air duct 9 is larger than the air outlet at the left end due to the space volume of the air inlet at the right end of the diffusion air duct 9, and the space volume component at the right end of the diffusion air duct 9 is reduced towards the air outlet at the left end, so that the air pressure is gradually enlarged and increased when pressure air advances in the diffusion air duct 9, under the condition that the power of the air blower is unchanged, the air pressure of the whole.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
