Dual-fan air supply device for fresh air purifier

Abstract

The invention relates to a dual-fan air supply device for a fresh air purifier and belongs to the field of ventilation system equipment. The dual-fan air supply device comprises fans and a shell. The shell is composed of a fan supporting shell and an air supply opening shell. The fan supporting shell is a triangular prismatic shell. Each of the two rectangular faces of the fan supporting shell is provided with a fan mounting opening. The rectangular faces where the two fan mounting openings are located form an included angle ranging from 100 degrees to 140 degrees. Each fan mounting opening is provided with one fan. The rectangular face without the fan mounting openings is connected with the air supply opening shell. The air supply opening shell is provided with an air supply opening. The air supply opening communicates with the two fan mounting openings. The structure is simple, the two fans are arranged, the effective air inlet area is increased, the air supply efficiency is high, and the whole set of device is small in noise and low in energy consumption.

Description

technical field [0001] The invention relates to a double fan air supply device for a fresh air purifier, which belongs to the field of ventilation system equipment. Background technique [0002] In existing buildings, fresh air purification system technology is more and more widely used, but the existing air supply devices usually have the following two problems. First, when the required air supply volume is large, the required fan The rated power of the control motor is large, so the noise generated by the fan is large and the energy consumption is high; secondly, there is only one fan in the air supply device, and the effective air intake area of ​​a fan is limited, thereby reducing the air supply efficiency of the blower. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide a fresh air air purifier dual-fan air supply device, which has a simple structure and is...
