Structure 2 and the second volute structure 3 are integrally formed with shell 1 respectively to be arranged.
As can be seen from the above description, the beneficial effects of the present invention are: first volute structure and the second volute structure point
It is not integrally formed and is arranged with shell, it is overall processing, rationally simple, it can integrated injection molding.Shell air-tightness after integrated molding
More preferably, intensity is higher.Meanwhile to replace or repairing blower unit, it is only necessary to take out or maintenance volute structure in wind wheel and
Motor is repaired and is safeguarded and is more convenient.
Further, the first opening 11, the first cover board 4, second opening 12 and the second cover board are respectively equipped on the shell 1
5；
First opening 11 is connected to the inner cavity of the first volute structure 2, and first cover board 4 detachably connects with shell 1
It connects and closes the first opening 11.
Second opening 12 is connected to the inner cavity of the second volute structure 3, and second cover board 5 detachably connects with shell 1
It connects and closes the second opening 12.
Seen from the above description, fan assembly by opening be placed in volute structure, then with cover board to volute structure into
Row sealing.
Further, first opening 11 and the second opening 12 are respectively arranged on the same side of shell 1.
Seen from the above description, two openings facilitate maintenance and installation personnel to make in the same side of shell positioned at the same side
Industry.
Further, first cover board 4, the second cover board 5 are threadedly coupled respectively with shell 1.
Seen from the above description, the connection type of threaded connection is convenient for disassembly and assembly.
Further, the side wall of first volute structure 2 is connected to the first opening 11, second volute structure 3
Side wall is connected to the second opening 12.
Seen from the above description, one of side wall when the first opening 11 of the first cover board 4 closing as the first volute structure 2
Point, the second cover board 5 closing second opening 12 when as the second volute structure 3 side wall a part, the opening on side wall can
It is larger with what is done, facilitate the installation of fan assembly.
Further, first volute structure 2 is close to one end of shell 1, and second volute structure 3 is close to shell 1
The other end.
Seen from the above description, two volute structures maintain a certain distance the generation that can reduce covibration, reduce whole
