Title:
AIR SUCTION TYPE NOZZLE HAVING IMPROVED AIR SUCTIONING OR LIQUID BACK-FLOW PREVENTING FUNCTION AND CHEMICAL, BIOLOGICAL, AND RADIOLOGICAL DECONTAMINATION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/097675
Kind Code:
A3
Abstract:
The present invention provides an air suction type nozzle which has an improved air suctioning function and is for suctioning air to spray the air together with a liquid. The nozzle is characterized by including: a casing (100) having a hollow formed therein; and an inner pipe (200) inserted into the casing (100), wherein a coupled structure of the inner pipe (200) and the casing (100) is divided, from the top, into a liquid injection part (A); a Venturi part (B); a mixing part (C); and a nozzle tip (D), an air orifice (210) through which air is suctioned is formed in the inner pipe (200) disposed in the Venturi part (B), and the air orifice (210) uses centrifugal force to boost the suctioning of air and is formed to be eccentric (e) from the center of the inner pipe (200) on a horizontal cross-section to enable the air and the liquid to flow smoothly.
