Problems solved by technology

[0002] Three-dimensional flow fans usually include series motors, three-dimensional flow impellers, three-dimensional flow fixed impellers, and air-collecting blades. The negative pressure generated by them can be used in vacuum cleaners and other places that require negative pressure. The air flow and pressure can be simultaneously Cool the series-excited motor, and the form of the impeller directly affects the size of the air flow and the efficiency of the three-dimensional flow fan, and also affects the temperature rise of the motor. Important, the conventional seal is fixed with screws, which not only has a complicated structure, but also causes air leakage and deformation of the air collection blade due to poor sealing, resulting in serious loss of air volume, generally high temperature rise, and low efficiency

Embodiment 1

[0021] see Figure 1-Figure 5 , as shown in the legend therein, a three-way flow fan includes a series excitation motor 1, a three-way flow impeller 4 connected to the series excitation motor 1, and a three-way flow impeller 4 located between the series excitation motor 1 and the three-way flow impeller 4 A three-dimensional flow fixed impeller 3 between them and the wind collecting vane 2 connecting the series motor 1 and the three-dimensional flow fixed impeller 3 .

[0022] The ternary flow fixed impeller 3 includes a disc 31, a number of blades 32 arranged spirally on the surface of the disc 31, an annular hub 33 connected to the outside of the blade 32, and two positioning columns 34 arranged on the disc 31, The positioning post 34 is also provided with a positioning portion 342 and a positioning post connecting hole 341 ; and the inner edge of the annular hub 33 is provided with four protrusions 331 .

[0023] The series-excited motor 1 includes a stator and a rotor, an...

Embodiment 2

[0035] The rest is the same as the first embodiment, except that the second connecting portion protrudes from the positioning portion and is sealingly attached to the end of the stator core.

[0036] The stator core 1 can be closely attached to the air collecting blades B2 and the fixed impeller 3, and then combined with the three-dimensional flow impeller 4 to achieve energy-saving and high-efficiency effects.

[0037] The beneficial effects of adopting the above technical solutions are: 1. The two materials are welded and fixed by the ultrasonic method. The welded product not only greatly increases the strength, but also significantly improves the phenomenon of air volume loss, and simplifies the processing procedure. At the same time, it can also improve the reliability and performance of the product; at the same time, it can save the cost increase caused by four screws; and the temperature rise is 10% lower than before the improvement, and the noise is also significantly im...

Abstract

The invention discloses a wind collecting sheet of a three-dimensional flow fan. The three-dimensional flow fan comprises a series excited machine, a three-dimensional flow moving impeller and a three-dimensional flow fixed impeller, wherein the three-dimensional flow moving impeller is in transmission connection with the series excited machine; the three-dimensional flow fixed impeller is arranged between the series excited machine and the three-dimensional flow moving impeller; the wind collecting sheet comprises a cone tubular wind collecting part, a first connecting part and a second connecting part, wherein the first connecting part is connected with the outer side of the port of the large end of the wind collecting part, and the second connecting part is connected with the outer side of the port of the small end of the wind collecting part; the first connecting part is ultrasonically welded to the three-dimensional flow fixed impeller; the second connecting part is hermetically connected with the series excited machine. Two materials are welded for fixation by adopting an ultrasonic method, so that not only is the strength of a welded product greatly improved but also the phenomenon of air volume loss can be obviously improved. The invention also discloses the three-dimensional flow fan.
