Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments to assist understanding of the invention. The method used in the utility model is a conventional method if no special regulation is provided; the raw materials and the apparatus used are, unless otherwise specified, conventional commercially available products.

Shown by fig. 1-3, the utility model provides a venetian blind formula distributor of admitting air, it includes upper plate 1, lower plate 2, curb plate 3 is located between upper plate 1 and the lower plate 2, curb plate 3 is four, locate the four corners of this venetian blind formula distributor of admitting air respectively, the one end of four curb plates 3 is connected with the both ends of two sides around upper plate 1 respectively promptly, the other end of four curb plates 3 is connected with the both ends of two sides around the lower plate 2 respectively, curb plate 3 plays the supporting role and links together upper and lower plate, middle cavity that forms. The left ends of the upper and lower bottom plates are also connected with a terminal sealing plate 5, the upper end of the terminal sealing plate 5 is connected with the left end of the upper bottom plate 1, and the lower end of the terminal sealing plate 5 is connected with the left end of the lower bottom plate 2.
