Abstract:
1. A spray gun structure, comprising a body equipped with an inlet duct and an assembling chamber extending on top of the inlet duct for the accommodation of a control valve therein wherein the control valve is equipped with water-sealing and water-influx areas and is synchronically actuated by an adjusting device to switch on/off water discharge thereby; besides, the body also includes a coupling end with a conjoining port therein extending forwards perpendicularly at one side of the assembling chamber for the accommodation of a coupling sleeve having a water-influx channel defining therein and a soft water-sealing sleeve mounted thereto; the water-sealing sleeve has one end defined by a concaved arcuate abutment surface to seal tight onto the protrusive arcuate surface of the water-sealing area of the control valve; the coupling sleeve also has protruding tracks extending at the internal surface thereon to fit to guide recesses of a water-guiding element equipped with an external-threaded portion thereon; the coupling end of the body thereof also has the external periphery equipped with a connecting section with protrusions extending thereon to match to a spray head thereby; the spray head has a central guide port with an internal-threaded portion extending at one side to secure to the external-threaded portion of the water-guiding element thereby; the water-guiding element has a water-guiding channel extending through the center therein and multiple water-outlet orifices annularly arranged at the outer periphery of one end to fluidly connect to the water-guiding channel for the transport of water flow thereby wherein both end sides of the water-outlet orifices thereof are respectively disposed a ringed groove for the accommodation of a watertight ring thereto so as to seal tight onto the internal surface of the guide port of the spray head thereby; the guide port of the spray head has one side equipped with water-guiding spaces with a larger-diameter receiving seat extending thereon to fit to a spray-varying plug mounted to the top end of the water-guiding element thereof; the guide port of the spray head also has the other side equipped with a conjoining end to which a water-sealing ring is mounted and a restrain collar is guided thereto; besides, the conjoining end of the spray head thereof is accommodated into the coupling end of the body to abut against the end edge of the coupling sleeve thereby, permitting the water-sealing ring to seal tight onto the internal surface of the coupling end thereof; the restrain collar has the internal surface symmetrically depressed with a set of resilient areas each equipped with a guide passage to form a restrain zone thereby wherein the restrain zones are respectively equipped with a restrain block defined by an oblique guide surface thereon to match to the protrusions of the body thereby; whereby, when the spray head is pivotally rotated to and forth in its own place, the water-guiding element can be synchronically actuated to move linearly forwards or backwards so as to adjust the location of the spray-varying plug and change the pattern of water spray thereby.
