Problems solved by technology

This will increase the cost, and in some special occasions, due to space constraints, multiple fans cannot be installed, which will affect production or use. In addition, the installation of external joints not only increases the cost but also greatly increases the air supply resistance, reducing the air volume. , the air supply efficiency is low, and the air supply volume of each joint cannot be controlled

Abstract

The invention provides a centrifugal fan. The centrifugal fan comprises a shell, a wind wheel, multiple wind door baffle plates, a rotating piece, and a transmission mechanism, wherein an intake space communicated with an intake port and multiple exhaust wind ways bent to extend are defined in the shell; the wind wheel is configured to accelerate air currents to flow in the shell from the intake port and to flow out of the shell by one or more of the multiple exhaust ports; the multiple wind door baffle plates respectively adjust the exhaust areas of the multiple exhaust ports or the exhaust wind ways; and the transmission mechanism is configured to transfer a rotating motion of the rotating piece to the multiple wind door baffle plates, so that the multiple wind door baffle plates move to respectively corresponding shielding positions. The centrifugal fan can drive the wind door baffle plates to rotate through rotation of the rotating piece to controllably shield the multiple exhaust ports so as to realize synchronous air supply in multiple directions, and can select the exhaust directions and adjust the exhaust quantities of all the exhaust ports to realize reasonable air supply.

Description

technical field [0001] The invention relates to the technical field of fan air supply, in particular to a centrifugal fan. Background technique [0002] Existing centrifugal fans are provided with only one air outlet. When it is necessary to supply air to two or more different directions or multiple positions, it is necessary to install multiple fans or add external joints matching the fans to meet the needs of different directions or locations. The demand for air supply in multiple locations. This will increase the cost, and in some special occasions, due to space constraints, multiple fans cannot be installed, which will affect production or use. In addition, the installation of external joints not only increases the cost but also greatly increases the air supply resistance, reducing the air volume. , the air supply efficiency is low, and the air supply volume of each joint cannot be controlled. Contents of the invention [0003] An object of the present invention is t...
