1. Field of the Invention
The present invention relates to a misting nozzle, and more particularly to a misting nozzle that can effectively mist water.
2. Description of Related Art
A conventional misting nozzle in accordance with the prior art shown in
When misting water, the rotor (20) is rotated in a high speed when high-pressure water flows into the body (10) and passed through the inclined face (22). As a result, the high-pressure water is misted and sprayed from the spray hole (31) after passing through the two guide grooves (21).
However, the rotor (20) is moved in the through hole (12) due to a pressure of the water that flows through the body (10) such that the gap between the top of the rotor (20) and the cap (30) is changeable. As a result, the water may not be misted when the pressure has been lowed and the gap between the top of the rotor (20) and the cap (30) has been enlarged.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional misting nozzle.
The main objective of the present invention is to provide an improved misting nozzle that can effectively mist water when the water pressure is low.
To achieve the objective, the misting nozzle in accordance with the present invention comprises a body having a through hole longitudinally and centrally defined therein. A flange radially extends from the body to divide the body into a connecting section and a mounting section, wherein the connecting section is adapted to be inserted into a hose/pipe. A cap is longitudinally and airtightly mounted to the mounting section of the body. The cap includes a cavity centrally and longitudinally defined therein. The cavity has a smooth portion formed near a bottom thereof. The cap includes a funnel-shaped hole centrally defined in the bottom of the cavity. A guide element is airtightly received in the smooth portion of the cavity, wherein the guide element has a thickness smaller than a depth of the smooth portion. The guide element includes an abutment airtightly abutting against the bottom of the cavity and an outer periphery airtightly abutting against an inner periphery of the smooth portion of the cavity. The guide element includes multiple ditches equally longitudinally defined in the outer periphery of the guide element. A round recess is centrally defined in the abutment and communicating with the funnel-shaped hole. Multiple grooves are respectively defined in the abutment. Each groove is defined along a corresponding one of the tangents of the recess and having two opposite ends respectively communicating with the recess and a corresponding one of the ditches, wherein each groove has a width and a depth respectively smaller than that of the corresponding ditch for raising the water pressure when passing therethrough.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The body (40) has a through hole (41) longitudinally and centrally defined therein. The body (40) includes an annular flange (42) radially extending therefrom to divide the body (40) into a connecting section (43) and a mounting section (44). The connecting section (43) is provides to be inserted into a hose or a pipe (not shown). In the preferred embodiment of the present invention, the connection section (43) is inserted to the hose and has a series of annular ratchet structures (431) for promoting a friction force between the connecting section (43) and an inner periphery of the hose. The mounting section (44) includes an annular groove (441) defined therein near the annular flange (43) and a threaded portion (442) formed thereon. An O-ring (45) is received in the annular groove (441).
The cap (50) has a cavity (51) centrally and longitudinally defined therein. The cavity (51) is divided into a smooth portion (511) and a threaded portion (512), wherein the threaded portion (512) is screwed onto the threaded portion (442) of the body (40) to make the distal edge of the cap (50) airtightly abutting the O-ring (45), and the smooth portion (511) has a diameter smaller than that of threaded portion (512) of the cap (50). A funnel-shaped hole (52) is defined in a bottom of the cavity (51).
The guide element (60) is airtightly received in the smooth portion (511), wherein the guide element (60) has a thickness smaller than a depth of the smooth portion (511). The guide element (60) includes an abutment (61) airtightly abutting against the bottom of the cavity (51) and an outer periphery airtightly abutting against an inner periphery of the smooth portion (511) of the cavity (51). The guide element (60) includes multiple ditches (62) equally longitudinally defined in the outer periphery of the guide element. A round recess (611) is centrally defined in the abutment (61) and communicates with the funnel-shaped hole (52). Multiple grooves (612) respectively defined in the abutment (61). Each groove (612) is defined along a corresponding one of the tangents of the recess (611) and has two opposite ends respectively communicating with the recess (611) and a corresponding one of the ditches (62). Each groove (612) has a width and a depth respectively smaller than that of the corresponding ditch (62) for raising the water pressure when passing therethrough.
With reference to
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
