Fluid pulse spraying device

Abstract

The invention relates to a fluid pulse spraying device, which comprises a shell and a piston. The piston enables a shell cavity to be separated into a water inlet cavity and a compression cavity, the water inlet cavity is connected with a fluid-power pressure source such as a water pump through a water inlet channel, a compression cavity water replenishing check valve and an elastic water stopping ring are arranged on the piston, a compression spring, a tower-shaped spring, a spheroidal elastic valve body and a spraying hole are arranged in the compression cavity, the compression spring is sleeved outside the tower-shaped spring, one end of the compression spring abuts against the piston, the other end of the compression spring abuts against the inner wall of the shell adjacent to the spraying hole, the large head end of the tower-shaped spring is fixed on the piston, the small head end of the tower-shaped spring is fixed on the spheroidal elastic valve body, and the curved surface ofan water inlet of the spraying hole is coincided with that of the spheroidal elastic valve body. The fluid pulse spraying device is simple in structure, free of electric drive and control, low in cost, convenient to use and particularly suitable for a pulse micro spray irrigation system, substitutes for a pulse solenoid valve deashing device of a bag-type dust collector, and can overcome the defect that a pilot hole is easy to block and be out of order, membrane opening time is long and membrane is short in service life.

AI Technical Summary

Benefits of technology

This patented technology solves problems associated with existing pulsed liquid misting devices that have complicated structures or are expensive to operate because they rely heavily upon electrical power sources like batteries. However, this new design offers technical benefits including improved durability without requiring frequent maintenance by replacing worn out components rather than rebuilding them once damaged. Additionally, there're no issues related to air pollution caused when used during cleanup procedures where disposable filters may be discarded after each usage period.

Problems solved by technology

This patent describes different methods for improving the efficiency of mistless irradiation processes without causing damage to cropping areas caused by excessive evaporation rates during use. One solution involves adding an atomizer to reduce vapor pressure and increase coolant flow rate, resulting in less resistance when relying upon gravity flows due to reduced hydraulic pressure. Another approach involves designing a new liquid pulsing jet irrigator system based on interference patterns generated by multiple wires instead of single ones.
