Abstract

The utility model relates to a terminal device for cleaning or spraying liquid, particularly a 'washing gun' that can change the state of spray streams. The utility model is composed of a Bernoulli's spray pipe, a flow valve, a flaky stainless steel block that is provided with different shapes of holes, and circular tubes that are provided with chutes and sheathed outside of the spray pipes. The flaky stainless steel block is manipulated to make a certain hole aim at spraying mouth so as to select the relevant shapes of streams. The utility model is, therefore, has convenient use and high spraying speed.

Description

Liquid spraying device

The utility model relates to and is used for a kind ofly being used to clean or the terminal installation of spraying liquid, what is called " ejecting gun " that particularly can conversion liquid stream spray regime.

Usually the implementation of this class device is more, achieve the goal by the difform shower nozzle that changes the outfit during enforcement, another United States Patent (USP) then is provided with garden post in axial sliding in jet pipe, penetrate the converter of shape as garden column or ring, but its annular jet is not easy to spray and washing, because internal drag is bigger, columnar jets firing rate under normal pressure is lower.

The utility model purpose is to obtain one can set the arbitrary shape jet, and " water pistol " of firing rate greatly arranged under normal pressure.

The utility model is that following mode realizes: a block that can radially slide and can stop in some positions is set outside Bernoulli Jacob's jet pipe, this block is flat preferably, as metallic plate, has difform hole on the block, as annular aperture, long and narrow hole etc.Open a hole more bigger again, be used to spray the garden columnar jets, handle moving of block, liquid stream is penetrated from a certain hole, just conversion jet form easily than nozzle hole.In order to prevent that liquid stream from leaking available elastomeric material packing between block and nozzle tube.Obviously, when liquid stream penetrates from the hole more bigger than spout, because of without hindrance again, thus jet velocity higher with adapt in requisition for.

Use the utility model, because conversion jet form is carried out outside jet pipe.Thereby seal request is low, and is simple in structure, can keep the higher spray regime of a kind of firing rate in multiple jet form.

Further provide the utility model below in conjunction with embodiment:

Direction Line 4 indications are Bernoulli Jacob's jet pipes among Fig. 1, be the sheet block 1 made of corrosion resistant plate in its front, have rubber seal 3 to prevent to leak between them, jet pipe 4 is the garden tubulose, another garden pipe 5 is being overlapped in the outside, sheet stainless steel block 1 is installed in pipe 5 grooves that can radially slide of garden, because the garden pipe is circlips 6 with the connection of jet pipe 4, so they can relatively rotate 360 degree and can not deviate from.7 one-tenth whole shapes of the shell of jet pipe 4 and flow valve, turning knob 8 is used to regulate the flow size, is with flexible pipe 10 in the flow valve back, and handle 9 is enclosed within flow valve 7 jet pipes 4 assemblys outside so that grip.

Among Fig. 2, sheet stainless steel block 1 is being opened hole, a garden 11, and what link with it is slit 12.In the present embodiment, the longitudinal axis of sheet stainless steel block 1, hole, garden 11, slit 12 overlaps.Contrast Fig. 1 as can be known, when block 1 when radially sliding, the spout of jet pipe 4 can be aimed at hole, garden 11 or slit 12 respectively, thus conversion jet form.

Another selection scheme that also proposes among Fig. 2 is to have increased ring-type seam 13, and it is positioned at hole, garden one end in the scheme, also can be positioned at the slit opposite side, and effect is identical.

Claims

1, the liquid ejector of forming by jet pipe, flat block, garden pipe, flow valve, handle and flexible pipe, it is characterized in that: in jet pipe 4 fronts are flat blocks 1, hole, garden 11, slit 12 are arranged on the flat block 1, flat block 1 can radially slide make liquid stream from hole, garden 11 and slit 12 pass through.

2, injector according to claim 1 is characterized in that: flat block 1 is positioned at the groove on the garden pipe 5, and garden pipe 5 is enclosed within jet pipe 4 outsides and can rotates relative to the axis of jet pipe 4.

3, injector according to claim 1 is characterized in that: jet pipe 4 is with handle 9 in flow valve 7, flexible pipe 10 outsides with flow valve 7, link with flexible pipe 10 again.
