Abstract
The utility model discloses an air entraining water jet pulse water syringe, which can jet water jet with better erosion capability when water pressure is relatively low. The water jet technology is applied to cleaning, spraying, digging aquatic plant rhizome and the like. After entering the water syringe, water flow is prepared into water jet, oscillated into air entraining pulse water jet and then is jetted from the water syringe. The air entraining pulse water jet can cause the cavitation phenomenon, so the erosion capability of the water jet is improved. The erosion effect of the water jet can be the same as that generated by the known water syringe in higher water pressure. When the water syringe is applied to the aquatic plant rhizome digging, after the air entraining pulse water jet enters underwater mud, uprising air also plows and turns the underwater mud and pushes the dug rhizome to float, so the digging efficiency is obviously improved. The recoil of the water syringe is weak, so the labour intensity of an operator is obviously reduced.
