Abstract

The utility model relates to a spray head for high pressure water gun, comprising a water supply connecting pipe, a sealing ring, a jet nozzle and a nozzle housing. A swirl plug for changing the direction of water flow is arranged between the water supply connecting pipe and the nozzle housing; a rotary spraying device is arranged in a swirl chamber surrounded by the swirl plug and the nozzle housing; the nozzle head of the rotary spraying device and a nozzle sheath positioned in the front-end of the swirl chamber are sliding contacted; an axial hammer is arranged in the back-end through-cavity of the rotary spraying device. High pressure water passes the water supply connecting pipe, and changes the flow direction via the swirl plug arranged in the rotary chamber into a radial flow, then sprays toward the inner wall of the nozzle housing to produce rotary water; the rotary water enables the water in the rotary chamber to rotate and drive the rotary device; then the high pressure water from the nozzle head is sprayed out in a form of spiral shape; when the high pressure spiral water is jetted to the snow or mud, the large area snow or mud is cleaned up. The washing efficiency is improved dramatically than that of the atmospheric pressure water gun; when washing the dirt in the tube, the rotary water column can wash the tube wall with high washing efficiency and save water.

Description

The giant injector head

Technical field

The utility model relates to a kind of water spraying structure of water pistol, the injector head that particularly a kind of giant is used.

Background technology

Water pistol is the instrument that people are used for cleaning dirt, carwash, pouring, along with the development and the living standards of the people of national economy constantly improve, this water spraying tool also improves constantly, CN97217974 proposes the water pistol that a kind of multisection type is regulated water spray water type, change water spray water type by multisection type spray pistol and nozzle boss movable connection structure, but it only is suitable for conventional hydraulic pressure, inapplicable giant.The rotary disk of water sprayer that CN00217701 proposes, the capstan surface is provided with inside loop and outside loop shape zone respectively, the hole for water spraying of water spray pore and multiple water spray water type is set on it, but it is still the sprinkler head of conventional hydraulic pressure, same inapplicable high hydraulic pressure, injector head are unable to bear that high hydraulic pressure impacts and badly damaged.Because giant is improving cleaning efficiency, using water wisely, particularly at the flushing main equipment, cleaning accumulated snow aspect is better than the normal pressure hydraulic giant, uses giant can save the water source, improves developing result, and its injector head improves and comes into one's own.

Summary of the invention

The utility model can not be used in the defective of giant at common water pistol injector head, designs a kind of hydraulic giant injector head that high hydraulic pressure impacts that tolerates, and reaches to improve impulsive force and not easy to wear, does not leak simultaneously, water-saving purpose.

Design of the present utility model is: the giant injector head, it comprises into water tube connector, sealing ring, jet blower and nozzle housing, it is characterized in that between water inlet tube connector and nozzle housing, establishing the eddy flow plug of changing the direction of a stream of water, in the eddy flow chamber of eddy flow plug and nozzle housing encirclement, establish a rotary-jet body, a plug hammer body is established in the nozzle cage sliding-contact of the nozzle head of rotary-jet body and eddy flow chamber front end in the accent of rotary-jet body rear end.

Above-mentioned design is that the water column of time ejection rotation of working for giant designs, because behind the water under high pressure process water inlet tube connector, flow to by changing in the eddy flow plug chamber in the middle of being located at, become radial flow, on the internal chamber wall of directive nozzle housing, producing eddy flow water makes the water rotation of eddy flow chamber drive the rotary fluid rotation, the water under high pressure shape ejection in the shape of a spiral that sprays through nozzle head again, when the spiral water flow directive accumulated snow of high pressure or mud, large tracts of land accumulated snow or mud can be rinsed well, than significantly improving, also reduce water consumption with normal pressure pistol flush efficiency.Effectively wash away tube chamber wall energy raising flush efficiency, conserve water with the rotation water column when being used to wash in the tube chamber dirt.

The specific embodiment

The utility model concrete structure is please referring to shown in Figure 1, water inlet tube connector 4 two ends outer walls are established connecting thread, wherein connecting thread 3 is connected with high-pressure water pipe with pressure-resistant seal circle 1 and tightens up in case sew, tighten up with being connected water pipe 4 connections by being located at nozzle housing 5, connecting thread 6 and pressure-resistant seal circle 19, with anti-leak.One end of eddy flow plug 7 is for aiming at the eddy flow plug tube chamber 20 of the intake antrum 2 that connects water inlet pipe, the other end is established eddy flow outlet pipe 8 for middle sealing along the tangential direction of tube chamber 20 inwalls, shown in Fig. 2-a and Fig. 2-b, eddy flow outlet pipe 8 is to be provided with along eddy flow plug inner chamber 20 wall tangential direction, and current penetrate and rotate near clockwise direction.The high-pressure water shot that this outlet pipe penetrates forms the helical form current and is full of the eddy flow chamber to the internal chamber wall of nozzle housing 5 in eddy flow chamber 9.Be rotary-jet body 10 in the eddy flow chamber 9 that is surrounded by jet blower shell 5 and eddy flow plug 7, rotary-jet body 10 is made up of the nozzle head 15 of front end, cone that the centre is cavity and the axle plug hammer body 18 of rear end.Nozzle body inner chamber 11 is the staged cavity, flexibly connects in the roomy chamber of staged cavity with the end plug that increases mobile hydraulic pressure, raising flushing mechanical axis plug hammer body 18.Because an axle plug hammer body is a metal, is generally copper material, the nozzle body cavity is a plastic cement, and when High-Pressure Water injected the eddy flow chamber, the high pressure water swelling of 60～70 MPas is opened nozzle body 10 chamber walls and in the flow nozzle body cavity 11, and was spouting in nozzle head cavity 16 again.Nozzle head 15 also has the staged tube chamber to run through, the lumen distal diameter is 0.95～1.5mm, this nozzle head is the round metal conical surface, the nozzle headgear 12 of nozzle head 15 relative fits is established the end of nozzle housing inner chamber therewith, the round metal conical surface of its indent is corresponding with the protruding taper seat of nozzle head 15, nozzle head 15 and nozzle headgear 12 are made by wear-resisting alloy, when being to slide to compress with the indent taper seat of the nozzle cage 12 that is located at eddy flow chamber front end, the outer conical surface of water under high pressure nozzle head 15 when nozzle head 15 ejects contacts, because the impetus of the rotational flow water in eddy flow chamber 9, nozzle body 10 rotates along its flow path direction of water, as shown in Figure 3, because the ratio of axle plug hammer body 18 is great, ejectisome 10 rotates along clockwise eddy flow chamber wall 9 as the rotation worm gear, and the water under high pressure of nozzle head 15 ejection also clockwise direction spray the water column of rotation, the rotary-jet water column is set by the injection subtended angle of nozzle cage and nozzle body end, the injection subtended angle 14 that generally is nozzle cage 12 is identical with the terminal subtended angle 13 of nozzle housing, between 90～100 degree.
