Specific embodiment
It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Figures 1 to 8, the utility model offer offer one kind subtracts sound nozzle arrangements, is to include：
One nozzle 10；Former nozzle 10 meets 11 and one outlet section of section, 12 system comprising one group and is made in a manner of being integrally formed, preceding
It states group and connects section 11 equipped with a groove 111,111 bottom surface 112 of aforementioned grooves immediately said outlet section 12, said outlet section 12 is by foregoing
It is formed at 111 bottom surface 112 of groove by nearly center flaring and uniform radial several entrances 113 outward, outside said outlet section 12
