Parallel type fan-powered variable-air-volume terminal device provided with air deflector structure

The utility model discloses a parallel type fan-powered variable-air-volume terminal device provided with an air deflector structure. The device comprises a box body, wherein a primary air inlet and a secondary air return port are formed in the front end of the box body, an air supply port is formed in the rear end of the box body, a primary air duct is arranged at the position of the air inlet, and a second air blower is obliquely arranged in the box body; a partition board isolating an air inlet of the secondary air blower from a primary air chamber and an air deflector isolating a primary air outlet and a secondary air outlet are arranged in the box body, and the internal space of the box body is divided into two independent cavities through the partition board, the tail end of the box body and the air deflector. According to the device, high static pressure is prevented from being generated on the lower side of a primary air valve when the secondary air blower is started, influence on primary air volume is reduced, and then primary air volume is effectively guaranteed.
