[0012] The beneficial effects of the utility model are:

[0013] The utility model provides a square diffuser, comprising a first connecting member, a second connecting member and a plurality of square frames; the plurality of square frames are arranged at equal intervals from the inside to the outside, and the plurality of square frames are connected by the first connecting member and the second connecting member; a connecting portion is provided at each of the four top corners of the square frame; the first connecting member and the second connecting member are arranged crosswise, and the first connecting member and the second connecting member are connected to the connecting portion by rivets. By providing the connecting portion at the top corner of the square frame, the position of the square frame can be flexibly adjusted during installation, and at the same time, after the installation position is determined, the connecting portion is connected and locked with the first connecting member and the second connecting member by rivets. The utility model provides a connecting portion at the top corner of the square frame, and the first connecting member and the second connecting member are connected to the square frame by rivets, so that a separate structure is formed between each square frame. Compared with the existing square diffuser, the utility model crosses the first connecting member and the second connecting member to rivet, which is convenient for installation, more beautiful without welding points, more environmentally friendly and firm without electric welding, simple structure, and the airflow blown out is of an attached type, which can be made into a multi-faceted air outlet type. At the same time, the utility model can be formed at one time by punching the aluminum plate in a punching die, so the production, forming and assembly efficiency are higher.
