Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Embodiment 1
A kind of Fan casing, as shown in Figure 1-2, including: Blower Housing 1 and base 2, the described dismountable company of Blower Housing 1
Being connected on base 2, have collecting driving means and the receiving space of impeller in described Blower Housing 1, described base 2 uses flexibility
Material is made, during to reduce fan operation with installed surface or earth shock produced by noise.Described Blower Housing 1 is also adopted by soft
Property material make, reduce further air-flow and the shock of Blower Housing 1 produced by described Fan casing inner accepting space and rub
Wipe, produced noise during reducing air-flow high-speed cruising.
Described Blower Housing 1 is spiral structure, and the opening of spiral structure is air outlet 12.The opening of described spiral structure
It is positioned at the side of Blower Housing 1, the discharge of air-flow in the setting of described air outlet 12 beneficially Blower Housing 1, and spiral structure
Air channel slow down the shock of air-flow and shell wall, reduces noise.
Being also associated with expanding air port 13 on described air outlet 12, described expansion air port 13 is more than the cylindric knot of import for outlet
Structure.The structure expanding air port 13 being arranged on air outlet 12, alleviates disorder and the shock of air-flow in Blower Housing 1 further,
Reduce the noise of high velocity air.
Described Blower Housing 1 be provided centrally with air inlet 11, the center of described Blower Housing 1 has upwardly extended one
