Abstract
The invention discloses a fan with an effect of prolonging the service life of an impeller. The fan comprises an air chamber shell, the impeller and a motor. The impeller comprises an upper end plate and a lower end plate which are parallel to each other, an air inlet is formed in the upper end plate, a plurality of main blades are uniformly distributed between the upper end plate and the lower end plate around the axial directions of the upper end plate and the lower end plate, an auxiliary blade is arranged between each two adjacent main blades, the orientation of each of the main blades and the auxiliary blades is consistent with directions from the axes of the upper end plate and the lower end plate to the outer edges of the upper end plate and the lower end plate, two side edges of each of the main blades and the auxiliary blades are fixed onto the opposite inner surfaces of the upper end plate and the lower end plate, elongated air holes are formed in the inner edges of the main blades, and the linear distance from the inner edge to the outer edge of each main blade is larger than the linear distance from the inner edge to the outer edge of each auxiliary blade. According to the technical scheme, the fan has the advantages that resistance on the blades can be reduced, and the service lives of the blades prolonged.
Description
Technical field
The present invention relates to a kind of impeller blower fan in working life that extends.
Background technique
Flow blower casing on market generally adopts the mode of iron plate punching press, riveted, cast iron, cast aluminium and injection moulding etc. to manufacture now, first produce by the way the two halves sheet of flow blower casing, then two halves sheet is spliced, although the structure good rigidly of this flow blower casing, transportation process in easily receive collision and damage, be inconvenient to transport and packing cost high, the blower fan of these structures aborning, need more staff assembling, manufacturing efficiency is low, and manufacture cost is high.
Impeller is as a key component of blower fan, and whether its structure setting rationally directly affects the overall performance of blower fan.In the process of work, vane rotary, drives gas flow, thereby realizes the dispatch to gas.Impeller when rotated air-flow can produce very large resistance to blade, and this resistance not only can affect the working life that the efficiency of blower fan also can reduce blade greatly.
Summary of the invention
The invention provides a kind of impeller blower fan in working life that extends, extend the working life of draught fan impeller.
The technical solution adopted in the present invention is to achieve the above object of the invention: a kind of impeller blower fan in working life that extends, comprise air compartment housing, impeller, motor, described air compartment housing is for adopting the integrated hollow cavity of blow molding process, accommodating impeller in described cavity, impeller is fixedly connected in the rotating shaft of motor, air compartment housing is provided with intake grill along the axial direction of machine shaft, and air compartment housing is along being provided with exhaust outlet perpendicular to the direction of machine shaft;
Described impeller comprises the upper head plate and the lower end sheet that be arranged in parallel, on described upper head plate, there is intake grill, on described, between lower end sheet around its axial uniform multiple primary blades, between adjacent two described primary blades, be provided with back blades, the trend of described primary blades and described back blades is from described, the axis of lower end sheet is to its outward edge direction, two sides of described primary blades and described back blades be all fixed on described on, on the relative internal surface of lower end sheet, the inside edge of described primary blades has rectangular wind hole, described primary blades inward flange to its outer peripheral crow flight distance is greater than described back blades inward flange to its outer peripheral crow flight distance.
Further, have multiple indent air channels that extremely described primary blades outward edge direction is extended from described wind hole in described primary blades, every described indent air channel has aperture near the outer peripheral end of described primary blades.
Further, described indent air channel is parallel to each other.
Further, described primary blades and described back blades are the arc shaped blade to same lateral bend.
Further, the described arc shaped blade of described primary blades and described back blades extends rear intersection and all forms a cylindrical shape, the round coaxial line that the outward edge of described cylindrical shape and described primary blades forms.
The invention has the beneficial effects as follows: adopt the integrated air compartment shell construction of blow molding process to replace existing spliced air compartment shell construction, therefore make the structure of whole blower fan more firm, corrosion protection, thereby various physical properties and the chemical property of air compartment housing have been promoted, meanwhile, can better resist the damage of product causing in the process of transportation, air compartment housing is one-body molded, can be directly and miscellaneous part be mounted with, improved manufacturing efficiency.
Adopt technique scheme, reduced the suffered resistance of blade, increased the working life of blade.
