During machine operation, air enters from entering cover intake grill, by impeller intake grill, takes turns drive be pushed to inducer by movable vane, discharges, then enter subsequent structural from upper each derivation air channel of inducer.In prior art, the vertical section of deriving air channel is generally trapezoidal (as shown in Figure 3) or other shape, this is because, inducer is generally that plastics are injection molded, during mold, larger with die cavity surface of contact, the structure that aspect ratio is higher, generally all need pattern draft, gradient is larger, the easier demoulding, and the gradient exhaust outlet passage (derivation air channel) that just causes is in trapezium structure, air is in exhaust outlet channel flow process, and the resistance of trapezoidal surface to wind just adds, and reduces efficiency.And in the utility model, adopt the derivation air flue structure (modes such as slow wire feeding cutting, blade insert can be adopted during manufacture) of rectangular cross-section, make air at the overall efficiency of deriving the reduction of the overall drag in air channel, raising motor, and (go out wind resistance little, turbulent flow, sinuous flow also can correspondingly reduce can to promote the uniformity of air-out, air flow path maintains ability grow, and air flow uniformity can promote).
Described wind-guiding wheel blade is curved, and described inducer number of sheets order is 5 to 36, and all wind-guiding wheel blades are evenly periphery centered by wheel disc axis.According to the purposes, model etc. of motor, comparatively suitable inducer number of sheets value can be chosen, obtain higher wind-guiding efficiency and good air-out effect.
Described fan housing comprises main cover body 14, is located at the convex cap 15 of lower cover on main cover body and outwardly, described cover intake grill is located on the convex cap of lower cover, described movable vane wheel comprises ring edge 16 under impeller body, impeller, described impeller air inlet is under impeller in ring edge, the convex cap inwall of described lower cover is provided with wheel cover seal ring 17, and described wheel cover seal ring contacts with ring edge under impeller.The convex cap lower end of described lower cover inwardly curls into ring groove, described wheel cover seal ring is fixed in ring groove, described wheel cover seal ring is provided with annular seal groove 18, the axis of annular seal groove and the dead in line of wheel cover seal ring, under described impeller, ring edge lower end is stretched in annular seal groove, under impeller, the outer side wall of ring edge contacts with the cell wall of annular seal groove, and under impeller, the madial wall of ring edge contacts with the cell wall of annular seal groove.Under described impeller, ring edge lower end is provided with round and smooth incision head, and under described round and smooth incision head and impeller, ring edge is formed in one structure, has surplus gap between described round and smooth incision head and the bottom land of annular seal groove.
Impeller body is for sending, one of wind-guiding main body main body, need between ring edge and the fan housing of motor under impeller to seal, and ring edge to move (during machine operation under impeller, impeller body, under impeller, ring edge all will rotate), so will motive sealing be realized, and the seal ring that under impeller, the easy scratch in ring edge lower end is common, and at the present embodiment, adopt the mode designing annular seal groove on seal ring, thus, under impeller, ring edge lower end can be stretched in annular seal groove, under such impeller, ring edge lower end is not just direct sealing contact surface, sealing contact surface becomes two sides of ring edge under impeller, so can both not easily scratch wheel cover seal rings, good motive sealing effect can be ensured again.In addition, the design in round and smooth incision header structure, surplus gap, also can reduce the damage to wheel cover seal ring, and can promote press seal effect.
Embodiment 2: the basic structure of the present embodiment and mode of execution are with embodiment 1, its difference is, as Fig. 7, shown in Fig. 8, described wind-guiding wheel blade is provided with a strip, there is flexible even wind paillon foil 19, described even wind paillon foil is in derives in air channel, all even wind paillon foils are evenly periphery centered by wheel disc axis, the wind-guiding wheel blade at all even with this wind paillon foil place, two ends of any one even wind paillon foil is connected, in the middle part of even wind paillon foil, outwardly convex forms arch arc, the direction of an even wind paillon foil arch arc outwardly convex is contrary with the arc protrusion direction of the wind-guiding wheel blade at this even wind paillon foil place.When motor speed is lower, can not ensure in each derivation air channel to have enough air, as easy as rolling off a logly occur the state that wind-guiding is uneven.And the existence of even wind paillon foil, effectively can limit single or that minority derivation air channel volume is large, other derives air channel volume deficiency situation.When air reaches derivation air channel fast, if transient flow is excessive, then can oppress the arch arc adduction of even wind paillon foil, and make urgent even wind paillon foil outward-dipping, thus allow the actual circulation bore of deriving air channel become large, and even wind paillon foil can produce certain elastic resistance, actual circulation bore is temporarily stoped to become large, so, in inducer, overall air-flow towards the derivation duct flows of little other those deficiency of airs of comparative resistance, just can will complete automatically " even wind " in a short period of time.And when air quantity becomes large, " even wind " also can be carried out at the beginning, and after air-out is stable, because even wind paillon foil is light, thin, the characteristic of bullet, even wind paillon foil significantly can be pressed, outwards be toppled over, and also can ensure smooth air-out.
Described wind-guiding wheel blade comprises phyllopodium 20, outer leaf margin 21, described outer leaf margin and phyllopodium hinged, described phyllopodium is provided with the spacing prolongation edge 22 rotated for limiting outer leaf margin, described outer leaf margin is provided with leaf margin groove, top spring 23 is provided with in described leaf margin groove, spring two ends, top connect phyllopodium, outer leaf margin respectively, outer leaf margin top overlays and leans against on spacing prolongation edge by described top spring, described spacing prolongation edge and phyllopodium are formed in one structure, and the usable rotational direction of an outer leaf margin is identical with the arc protrusion direction of the wind-guiding wheel blade belonging to this outer leaf margin.
When turnover air-flow is not very large, under the effect of top spring, outer leaf margin can not move.When passing in and out air-flow and being very large, outer leaf margin can be promoted when the discharge air-flow of inducer (deriving in air channel) reaches outer leaf margin and outwards rotate (air quantity is large, so there is the trend expanding exhaust port) along articulating point.We know, no matter with or without even wind paillon foil, the air-flow of deriving in air channel has the trend towards the flowing of inducer leaf inner fovea part direction, this is because air-flow flows along curved channel, all the time velocity attitude is always towards tangential, and due to the stop of follow-up wind-guiding wheel blade, so air-flow can only continue to flow along the arc inner edge (recess) of wind-guiding wheel blade, and along the air that (convex place) outside the arc of wind-guiding wheel blade flows, owing to being also tangential flowing, so constantly have disengaging, away from the trend of wind-guiding wheel blade, this just causes, and said air is above concentrated to flow towards recess.So, although each outer leaf margin outwards rotates, the actual exhaust port expanded is limited (for a derivation air channel, an outer leaf margin is had outwards to rotate, another outer leaf margin is just had inwardly to rotate), but the air that the outer leaf margin outwards rotated goes out to discharge is more concentrated, so improve air draft ability (concentrated air flow energy leaves inducer quickly) comparatively speaking or effectively.
Be located at the two ends of the even wind paillon foil on a wind-guiding wheel blade, respectively be under the jurisdiction of the phyllopodium of this wind-guiding wheel blade, outer leaf margin is connected.When outer leaf margin rotates, explanation air quantity is large, now, the rotation of outer leaf margin can drive outside one end (outer end) of even wind paillon foil and move, be equivalent to elongate even wind paillon foil, so, the degree of convexity of even wind paillon foil arch arc just considerably reduces, so initial air draft bore automatically can be expanded when air quantity is large, be more conducive to smooth, uniform air draft.
