Problems solved by technology

[0002] Traditional high-pressure, high-speed fans are generally oblique flow fans. There is a hub in the middle of the oblique flow fan blades, and the air can only enter from the outside of the hub. As a result, there are some invalid air intake areas in the oblique flow fan, which affects the air intake of the oblique flow fan. , and the air forms a turbulent flow in this area, which interferes with the normal air intake of the diagonal flow fan and affects the wind pressure and air output of the diagonal flow fan

Abstract

The invention discloses a combined fan blade and a combined air outlet device.The combined fan blade comprises a hub, oblique flow fan blades and centrifugal fan blades, a first air inlet is formed between the hub and a flow guide cover, the first end of the hub and the flow guide cover form a first air outlet, a second air inlet is formed in the first end of the hub, and the first air inlet is annularly formed in the outer side of the second air inlet; the second end of the hub is provided with a second air outlet, and the oblique flow fan blades and the centrifugal fan blades are connected to the two sides of the hub correspondingly. The combined air outlet device comprises the combined fan blade. According to the air outlet device, the air inlet area, on the air inlet side, of the hub can be fully utilized, the air inlet amount is increased, the oblique flow fan blades and the centrifugal fan blades can respectively form two paths of airflow, the two paths of airflow are converged after being discharged from the air outlet, and the air volume and the air pressure of the air outlet device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of air outlet structures, in particular to a combined fan blade and a combined air outlet device. Background technique [0002] Traditional high-pressure, high-speed fans are generally oblique flow fans. There is a hub in the middle of the oblique flow fan blades, and the air can only enter from the outside of the hub. As a result, there are some invalid air intake areas in the oblique flow fan, which affects the air intake of the oblique flow fan. , and the air forms a turbulent flow in this area, which interferes with the normal air intake of the diagonal flow fan and affects the wind pressure and air output of the diagonal flow fan. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a combined fan blade, which can make full use of the air inlet area of ​​the fan blade and incr...
