Abstract

An integrated device for water streaming and spraying comprises a support base, a water inlet pipe mounted on the support base, a nozzle including an outer tube mounted on the water inlet pipe and an inner tube, an adjustment sleeve making sealing contact with the outer tube, and a position adjustment mechanism capable of adjusting a position of the adjustment sleeve along front and rear directions. The inner tube provided with a plurality of guide vanes is disposed in and protruding from the outer tube. A cavity of the inner tube is provided with a partition plate, the partition plate and an inner wall of the inner tube together encircle to form an opened diversion groove having a groove wall provided with at least one notch. The adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the opened diversion groove.

First claim

What is claimed is:

an adjustment sleeve, the adjustment sleeve being sleeved on an outer side of the outer tube;
a position adjustment mechanism capable of adjusting a position of the adjustment sleeve along the front and rear directions;
a rear end of the outer tube communicating with the front end of the water inlet pipe, the inner tube being disposed in a cavity of the outer tube;
a front end of the inner tube protruding from a front end opening of the outer tube;
a cavity of the inner tube being provided with a partition plate, the partition plate and an inner wall of the front end of the inner tube together encircling to form an opened diversion groove;
a groove wall of the opened diversion groove being provided with at least one notch;
an outer side surface of the inner tube being provided with a plurality of guide vanes arranged in a circumferential direction of the inner tube;
an outer edge of each of the guide vanes contacting and fitting with an inner side surface of the outer tube;
an inner side surface of the adjustment sleeve making sealing contact with an outer side surface of the outer tube;
