1results about How to "Guaranteed air intake efficiency" patented technology

This utility model provides a fan assembly and a range hood. The fan assembly includes a fan and a bracket assembly. The fan has a volute and an external rotor motor. The volute forms a mounting cavity, and the external rotor motor is at least partially located within the mounting cavity. The bracket assembly has a first bracket and a second bracket, which are staggered and overlapped. The first bracket has a first mating part, and the second bracket has a second mating part. The volute has an air inlet side, and the ends of both the first and second brackets are connected to the air inlet side. One end of the central shaft of the external rotor motor passes through the first and second mating parts sequentially to connect to the bracket assembly. This effectively improves the robustness and reliability of the connection between the external rotor motor and the volute. Furthermore, the simple structure of the bracket assembly effectively ensures the air intake efficiency of the external rotor motor. Moreover, the assembly process of the bracket assembly is simple, effectively improving the convenience and efficiency of fan assembly.
