Specific embodiment
To describe technology contents of the invention, structural features in detail, purpose and effect being realized, below in conjunction with embodiment And coordinate accompanying drawing to be explained in detail.
Referring to figs. 1 to Fig. 4, the invention discloses a kind of split impeller 100, including outer kuppe 10 and Inner guide cover 20, Several first blades 31 are provided with a determining deviation on the inwall 11 of the outer kuppe 10, on the outer wall 21 of the Inner guide cover 20 Several second blades 32 are provided with a determining deviation, the Inner guide cover 20 and outer kuppe 10 coordinate to be installed, so that described first The blade 32 of blade 31 and second is interspersed to form diversion air duct 30 with a determining deviation.
Wherein, with reference to Fig. 1 and Fig. 2, the outer kuppe 10, by injection moulding integrated molding, is inside led with first blade 31 Stream cover 20 passes through injection moulding integrated molding with second blade 32.The outer wall phase of first blade 31 and the Inner guide cover 20 Even, second blade 32 is connected with the inwall of the outer kuppe 10.Wherein, above-mentioned first blade 31 and the Inner guide cover 20 outer wall only contradicting or can be connected together, it is also possible to while fixed by glue, second blade 32 with it is described The inwall of outer kuppe 10 only contradicting or can be connected together, it is also possible to while being fixed by glue.
With reference to Fig. 3 and Fig. 4, the edge of second blade 32 is convexly equipped with the first holding section 321, the outer kuppe 10 Inwall is provided with and is arranged with the first slot 322 being connected together with first holding section 321, the side of first blade 31 Along the second holding section 311 is convexly equipped with, the outer wall of the Inner guide cover 20 is concavely provided with and is connected together with second holding section 311 The second slot 312.First slot 322 and the second slot 312 are capable of achieving the leaf of the second blade 32 and the first blade 31 Heel teeth closes weakening.Wherein, the holding section 321 of first holding section 311 and second is respectively and is convexly equipped in the He of the second blade 32 The raised line at the edge of the first blade 31, the slot 312 of first slot 322 and second is respectively recessed in the outer water conservancy diversion Strip groove on cover 20 and Inner guide cover 10.Certainly, first holding section and the second holding section can also be convex for several Point, first slot and the second slot can also be the groove of correspondingly-shaped.
With reference to Fig. 3 and Fig. 4, first blade 31 to the direction extension of adjacent first blade of either side is formed with synchronous arm 41, the outer wall 21 of the Inner guide cover 20 is located at the position between adjacent second blade 32 (with 31 pairs, first blade The position answered) it is formed with the synchronous groove 42 being connected together with the synchronous arm 41.Wherein, the synchronous groove 42 is formed at bar Second slot 312 of shape closes on the one end in axle center, and now, the synchronous groove 42 is connected with the strip groove 312, institute State synchronous arm 41 and be formed on first blade 31 one end for closing on the axle center of split impeller 100.
With continued reference to Fig. 3 and Fig. 4, the outer kuppe 10 closes on the position in the axle center of split impeller 100 and is provided with positioning Card column 51, the position that the Inner guide cover 20 closes on the axle center offer orientation draw-in groove 52, it is described positioning card column 51 with it is described Orientation draw-in groove card 52 closes connection so that the outer kuppe 10 and Inner guide cover 20 complete the assembling of preset direction.
Wherein, first blade 31 is thick with the leaf of second blade 32 and/or chamfering is different, first blade 31 Odd number is with the number of the second blade 32.Number of each group intra vane is odd number, it is to avoid symmetrically resonance is existing for even number As, the resonance of blade antithesis is reduced, the leaf thickness and/or chamfering of difference group blade is different so that flutter frequency between difference group blade Difference, blade does not resonate between group and group, effectively reduces the noise of resonance and blade vibration.In the present embodiment, per group Blade has 5.
Wherein, when split impeller of the present invention makes, the modes such as injection can be first passed through and makees kuppe out and interior respectively Kuppe, several first blades are provided with the inwall of the outer kuppe with a determining deviation, on the outer wall of the Inner guide cover with One determining deviation is provided with several second blades, then the Inner guide cover and outer kuppe are coordinated into installation, so that first blade It is interspersed to form diversion air duct with a determining deviation with the second blade.
Wherein, first blade and the second blade are helical blade, especially logarithmic spiral blade, the wind-force of impeller It is big and steady.
In the present embodiment, the number of the blade 32 of first blade 31 and second is equal.
Above disclosed is only the preferred embodiments of the present invention, can not limit the right of the present invention with this certainly Scope, therefore the equivalent variations made according to scope of the present invention patent, still belong to the scope that the present invention is covered.
