Specific embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality The limitation of type.

First below the impeller 100 according to the utility model first aspect embodiment is specifically described with reference to accompanying drawing 1 to Fig. 5.

Impeller 100 according to the utility model embodiment includes：Pedestal 10, multiple first blades 20 and at least one second Blade 30.

Specifically, pedestal 10 is that the outer peripheral face of disc and pedestal 10 is arc-shaped surface, multiple edges of first blade 20 Circumferentially-spaced the opening of pedestal 10 is evenly arranged on the outer peripheral face of pedestal 10, the outer wall of two neighboring first blade 20 and pedestal 10 Exhaust passage is limited between face, the one end of the first blade 20 on the axial direction of pedestal 10 is entrance point, and the other end is the port of export, at least one Individual second blade 30 is located in the outside wall surface of the first blade 20, and the one end of the second blade 30 on the axial direction of pedestal 10 is (in block body axis Upward lower end) it is concordant with the port of export of the first blade 20.

In other words, the impeller 100 is mainly made up of pedestal 10, multiple first blades 20 and multiple second blades 30, pedestal 10 distributions in disk form, the side wall of pedestal 10 is arc-shaped surface, along the outer peripheral face (outer peripheral sidewall of pedestal 10 of pedestal 10 Face) on be provided with multiple first blades 20 evenly and at intervals, i.e., multiple first blades 20 are spaced apart and are uniformly arranged in pedestal On a 10 circle outer peripheral face, respectively approximately along the axially extending of pedestal 10, multiple first blades 20 exist each first blade 20 It is distributed in swirl shape on the outer peripheral face of pedestal 10, is limited jointly with the periphery wall of pedestal 10 per two adjacent the first blades 20 Exhaust passage, the first blade 20 forms entrance point, lower end shape of first blade 20 in the axial direction of pedestal 10 in the upper end of the axial direction of pedestal 10 Into the port of export, the fluid (air-flow or current) entered from the import of impeller 100 can enter air channel by entrance point, then by port of export stream Go out.

Additionally, being provided with the second blade 30 at the port of export in the first blade 20, the second blade 30 is arranged in the first leaf In the outside wall surface of piece 20, and lower end of second blade 30 on the axial direction of pedestal 10 keeps flat with the port of export of the first blade 20 Together, i.e. the port of export of lower end of the second blade 30 on the axial direction of pedestal 10 and the first blade 20 is in the same horizontal line (such as Fig. 2 institutes Show), the setting of the second blade 30 can improve the distribution of fluid flow fields in air channel, and the fluid by the port of export out is drawn Lead.

Thus, the impeller 100 according to the utility model embodiment, second is set by the outside wall surface of the first blade 20 Blade 30, and make the port of export flush of lower end of second blade 30 in the axial direction of pedestal 10 and the first blade 20, fluid by The entrance point in the air channel that the first adjacent blade 20 is limited with the outside wall surface of pedestal 10 enters air channel, is reached via air channel and exported End, the second blade 30 can be guided to the fluid in air channel, optimize Flow Field Distribution, even if fluid when operating mode changes Blade will not be struck, reduces the Damage for Detention of fluid, improve the fluid angle of attack, be not susceptible to vortex and fluid is separated, and then drop The vibrating noise of low impeller 100, improves the performance of fluid in air channel, lifts the operating efficiency of impeller 100.The knot of the impeller 100 Structure is simple, can optimize Flow Field Distribution, so as to improve the performance of impeller 100, reduces the Damage for Detention of fluid, high working efficiency, noise It is low.

Alternatively, the second blade 30 includes multiple, and each second blade 30 is respectively provided at the port of export of the first blade 20 In outside wall surface, that is to say, that have multiple second blades 30 on impeller 100, each second blade 30 is separately positioned on correspondence In the outside wall surface of the port of export of the first blade 20, i.e., each second blade 30 is located at corresponding first blade 20 in pedestal 10 respectively In the outside wall surface of the lower end on axial direction, being arranged on the second blade 30 of the port of export of the first blade 20 can form drawing for guiding fluid Guide face, enters into drive device (not shown) with being conducive to the smooth fluid for flowing out impeller 100.
