Abstract
The utility model discloses an axial flow fan comprising a stator outer frame and impellers. A gap is remained between the stator outer frame and each impeller, and a dirt-proof boot is arranged between the stator outer frame and each impeller. By using the dirt-proof boot, the axial flow fan prevents dust and batt from entering into the gap between the stator outer frame and each impeller, thereby protecting a motor form dust jamming or burning and prolonging the service life of the fan.

Blower fan is a kind of driven fluid machinery, and it relies on the mechanical energy of input, improves gas pressure and transfers out gas.Being of wide application of blower fan, as be used for ventilation, dust discharge and the cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and the domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
The equidirectional blower fan of axle of the flow direction of wind and blade is an axial-flow blower.As shown in Figure 1, axial-flow blower of the prior art comprises stator housing 101, impeller 102, several pieces blades 103 and motor 104, described stator housing 101 is supporting motor 104, base as motor 104, described several pieces blades 103 equidistantly are distributed in the outer wall of impeller 102, the diameter of described stator housing 101 has a gap 105 less than the diameter of impeller 102 between stator housing 101 and impeller 102.When this axial-flow blower is installed in the more rugged environment of dust (as spinning and weaving workshop), dust in air, cotton-wool easily enter the gap 105 between stator housing 101 and the impeller 102, and filling gap 105, after blower fan uses a period of time, dust, the cotton-wool of staying gap 105 between stator housing 101 and the impeller 102 block motor 104, motor 104 can't normally be rotated, even burn motor 104, thereby damage blower fan.
The model utility content
The purpose of this utility model is to provide a kind of axial-flow blower, uses dirt-proof boot to stop airborne dust to enter gap between stator housing and the impeller, prevents that dust from blocking or burn motor, prolongs the working life of blower fan.
To achieve the above object, the utility model provides a kind of axial-flow blower to comprise stator housing and impeller, and is gapped between described stator housing and the impeller, is provided with a dirt-proof boot between described stator housing and impeller.
Above-mentioned axial-flow blower, wherein, the outer wall of described stator housing is provided with a grooved ring.
Above-mentioned axial-flow blower, wherein, described dirt-proof boot comprises connecting ring and dust ring, and described dust ring is arranged on the outer wall of connecting ring, and described connecting ring is stuck in the grooved ring on the stator housing outer wall, and described dust ring is sealed the clearance aperture between stator housing and the impeller.
Above-mentioned axial-flow blower, wherein, described dust ring is perpendicular to the outer wall of connecting ring.
Above-mentioned axial-flow blower, wherein, described dust ring contacts with the end of impeller near the stator housing.
Above-mentioned axial-flow blower, wherein, described dust ring contacts with the inwall of impeller.
Above-mentioned axial-flow blower, wherein, described dirt-proof boot is made by silica gel.
The utility model axial-flow blower is owing to establish dirt-proof boot between stator housing and impeller, dirt-proof boot has been sealed the clearance aperture between stator housing and the impeller, prevent that effectively airborne dust, cotton-wool from entering the gap between stator housing and the impeller, thereby avoid motor to be blocked or burnt, prolonged the working life of axial-flow blower.
