Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Referring to figs. 1 through Fig. 6, a kind of spray gun of the present invention, comprise the rifle body 1 of a bending, rifle body 1 inside is provided with water stream channel, rifle body 1 two ends are respectively arranged with water inlet 11 and delivery port 12, water inlet 11 is for being connected with aqueduct, delivery port 12 is connected with nozzle 2, rifle body 1 upper end is also connected with the handle 3 for controlling water spraying mode, the recessed formation in rifle body 1 upper end fluted 13, handle 3 is provided with the base 31 suitable with groove 13, base 31 lower surface and handle 3 body are obliquely installed, handle 3 is rotatably installed in groove 13 by base 31, base 31 lower end is connected with valve core rod 4, valve core rod 4 slides and is arranged in water stream channel and is connected to nozzle 2 upper port by being connected with spring base 5, valve core rod 4 lower end sidewall is provided with the tank 41 allowing current pass through.This spray gun is provided with two kinds of water spraying modes, squeeze grip during general mode, handle grip movable valve plug bar lower end 4 departs from nozzle 2 upper port makes current enter nozzle 2 from tank 41, thus realize spray gun water spray, unclamp handle, valve core rod 4 resets and seals nozzle 2 thus make spray gun stop water spray under spring base 5 promotes, during permanent pattern, handle 3 pull-up upset is fixed in groove 13, valve core rod 4 is made to depart from nozzle 2 upper port, thus do not need user's Continued depression handle 3 can realize the lasting water spray of spray gun, reduce the exhausted sense of user operation during long-time water spray operation, improve the operating experience of user, this spray gun is by being provided with two kinds of water spraying modes, make people can select different water spraying modes according to actual needs, it is simple to operate, easy to use, improve the convenience that user uses.

Concrete, base 31 bottom is provided with mounting groove 310, mounting groove 310 sidewall is provided with hinge hole 311, the distance of hinge hole 311 central axis and base 31 lower surface is less than it respectively and base 31 is left, the distance of right side, valve core rod 4 upper end puts in mounting groove 310 and is interspersed in hinge hole 311 by jointed shaft and is hinged with base 31, when squeeze grip 3, the base 31 of handle 3 lower end and then overturns and then passes through jointed shaft pull-up valve core rod 4, valve core rod 4 lower end is made to depart from nozzle 2 upper port, thus realize water spray, when needs are sprayed water for a long time, only need pull-up handle 3, fitted in the upset of the left side of base 31 and mounting groove 310 bottom surface fixing, because hinge hole 311 and the distance of base 31 left side are greater than the distance of itself and base 31 lower surface, thus make the valve core rod 4 be articulated with on base 31 be departed from nozzle 2 upper port by lifting, achieve the lasting water spray of spray gun.

In the present invention, groove 13 sidewall stretches out and is formed with lead 130, base 31 is provided with the gathering sill 312 suitable with lead 130, by coordinating of lead 130 and gathering sill 312, before and after making base 31, both sides are limited, when press or pull-up handle 3 time, handle 3 can only spin upside down, when avoiding handle 3 to promote by external force, swing affects operation, and the setting of lead 130 and gathering sill 312 improves the operational stability of this spray gun, makes the operating experience of user better.

Better operating handle is obtained for making user, handle 3 lower surface indent is formed with Handheld Division 32, by being provided with the Handheld Division 32 of indent, when making user hold handle 3, part muscle is on hand absorbed in Handheld Division 32, increases the frictional force of user's hand and handle 3, improve the gripping sense of user, make user can pull-up or squeeze grip 3 easily, avoid user to be difficult to operate spray gun under hand such as to get wet at the situation that hand relatively slides, improve the convenience that user uses.

In the present invention, nozzle 2 is threaded delivery port 12 being sealed by seal, be threaded efficient and convenient, user can change rapidly dissimilar nozzle 2 as required, nozzle 2 is sealed by seal simultaneously, when avoiding spraying water, water leaks out from nozzle 2 and the junction of delivery port 12 clothes drenching user, improves the convenience that user uses.

Be connected with outside aqueduct for ease of spray gun, water inlet 11 outer wall is provided with connecting thread, connecting thread is preferably general GB screw thread, and to make this spray gun be connected with other aqueducts as far as possible, the nominal diameter injection flow rate according to actual needs of connecting thread is selected.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
