PURPOSE: To prevent the return of the products to be diffused into a means for transporting the products by consisting a nozzle of a central duct and a head forming a hollow part and providing a side part duct having its end at nearly the same height as the height of a hole disposed at the hollow part. CONSTITUTION: This apparatus consists of a container 7 for contg. the products to be diffused, the means E for transporting fluid through the nozzle 5 and a means C for controlling the transporting means E. The nozzle 5 consists of the central duct 5b connected to a carrier fluid generator 3 and the head 5a for forming the hollow part 14 across part of the length of the duct 5b together with the duct 5b. The hollow part 14 is designed to allow the passage of the carrier fluid and has one hole 15. Further, the nozzle 5 is provided with the side part duct 6 which is installed in parallel with the duct 5b, is provided with the one end soaked into the fluid to be diffused and has the other end at nearly the same height as the height of the corresponding hole 15. Consequently, the return of the products to be diffused to the means E is prevented. |
