At present, the spherical blower fan of the mixed-flow on the market mainly comprises air intake lid, air-out lid, centrifugal fan and electric machine support.Its ubiquity noise is big, and air quantity does not increase, and manufacturing process is loaded down with trivial details, and the product cost height has seriously restricted the prospect of product on market.

The model utility content

The purpose of this utility model provides that a kind of noise is little, and air quantity is big, the spherical blower fan of a kind of mixed-flow that manufacturing process is simple, cost is low.

In order to achieve the above object, the utility model is achieved in that it is the spherical blower fan of a kind of mixed-flow, comprises air intake lid, the air-out lid that cooperates with the air intake lid, is located at the fan assembly between air intake lid and the air-out lid; It is characterized in that: on the inwall of described air-out lid, be provided with the guide plate more than three that the gas that fan assembly is extracted out plays guide functions.

One end of described guide plate extends to the air-out port of air-out lid, thereby the effect of strengthening is built in air-out.

Described fan assembly comprises motor, by the rotating disk of driven by motor, is fixed on the fan blade more than three on the rotating disk and is fixed on air guide hole on the fan blade; Center in the air-out lid is provided with mounting plate, and motor is fixed on the mounting plate; The section of rotating disk is " eight " font, is convenient to water conservancy diversion; It is horn-like that air guide hole is, and its wind inlet is facing to the intake grill of air intake lid.

The other end of described guide plate stretches out the air-out lid and is positioned at outside the fan blade, better the gas flow guiding that fan blade is extracted out.

The section of described guide plate is curved, and the scope of its Inlet cone angle a1, exit angle a2 is 30 ° to 60 °.

Described mounting plate is fixed on the guide plate.

The section of described fan blade is curved, and the scope b1 of its Inlet cone angle is 30 ° to 60 °, and the scope b2 of exit angle a is 30 ° to 60 °.

The scope of the total length L 1 of described air intake lid and air-out lid is the 210-270 millimeter, and the scope of the diameter D2 of the exhaust outlet of the diameter D1 of the intake grill of air intake lid and air-out lid is the 145-165 millimeter.

The exit width scope of described blade (32) is the 55-75 millimeter, and the throat width scope is the 65-85 millimeter.

The utility model advantage compared with prior art is, because the effect of guide plate is arranged, can effectively get rid of the vortex flow that gas forms in spiral case, thereby reduce noise greatly, improved air output, and rational in infrastructure, manufacturing process is simple, cost is low.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Shown in Fig. 1 to 11, it is the spherical blower fan of a kind of mixed-flow, comprises air intake lid 1, the air-out lid 2 that cooperates with the air intake lid, is located at the fan assembly 3 between air intake lid and the air-out lid.The scope of the total length L 1 of air intake lid and air-out lid is the 210-270 millimeter, and the scope of the diameter D2 of the exhaust outlet of the diameter D1 of the intake grill of air intake lid and air-out lid is the 145-165 millimeter.On the inwall of air-out lid, be provided with the guide plate more than three 4 that the gas that fan assembly is extracted out plays guide functions, in this example, be provided with five guide plates, the section of guide plate is curved, the scope of its Inlet cone angle a1, exit angle a2 is 30 ° to 60 °, one end 41 of all guide plates extends to the air-out port of air-out lid 2, thereby the effect of strengthening is built in air-out, makes its more reasonable structure.Fan assembly 3 comprises motor 31, by the rotating disk 34 of driven by motor, is fixed on the fan blade more than three 32 on the rotating disk and is fixed on air guide hole 33 on the fan blade; In the present embodiment, have nine fan blades, its section is curved, and the scope b1 of its Inlet cone angle is 30 ° to 60 °, is the scope b2 of exit angle a? 30 ° of exit width scopes to 45 ° of blades are the 55-75 millimeter, and the throat width scope is the 65-85 millimeter; The section of rotating disk 34 is " eight " font, is convenient to water conservancy diversion; It is horn-like that air guide hole is, and its wind inlet is facing to the intake grill of air intake lid 1.The other end 42 of guide plate 4 stretches out air-out lid 2 and is positioned at outside the fan blade 4, better the gas flow guiding that fan blade is extracted out.Center in air-out lid 2 is provided with mounting plate 5, and motor 31 is fixed on the mounting plate, and in the present embodiment, mounting plate is fixed on the guide plate 4.

During use, connect power supply, fan assembly 3 work, gas flows out from air-out lid 2 from the wind inlet suction of air intake lid 1 again.Because guide plate 4 is arranged, can effectively get rid of the vortex flow that gas forms in spiral case, reduced noise, improved gas output; Extend to the air-out port of air-out lid again owing to one proper 41 of guide plate, it has been played the use of strengthening, effectively reduced the cost of product.
