It extend into water cavity leading portion and is inserted into the pilot hole of spray head, spring element is arranged in pilot hole and contact guide part.
Among one preferred embodiment: further including locating piece and card-bit part, the locating piece is connected on the side wall of spray head, institute
It states card-bit part to be fixed in casing, locating piece is located at the rear side of card-bit part, and spray head stops when locating piece is pressed against with card-bit part
Only move forward.
Among one preferred embodiment: further including mandrel, mandrel is arranged in casing, and mandrel is equipped with water passage, Guo Shuitong
Road is connected with water cavity.
Among one preferred embodiment: further include be arranged on mandrel for switch water passage by pressure valve.
Among one preferred embodiment: described by pressure valve includes sealing axis and spring, press sealing axis open water passage with
The connection of water cavity, spray gun are in water flowing state；Release sealing axis, spring promotion sealing axis reset closing water passage and water cavity
Connection, spray gun are in state of cutting off the water supply.
Among one preferred embodiment: casing is equipped with button, and button is abutted with sealing axis.
Among one preferred embodiment: when hydraulic pressure >=0.1MPA, water can push spray head to move forward stretching casing.
Among one preferred embodiment:
The technical program compared with the background art, it has the following advantages:
1. when not in use, spray head is pressed into casing by elastic component, apopore is hidden；In use, water enters spray head, hydraulic pressure
It acts on spray head and pushes spray head that the elastic force of elastic component is overcome to move forward and stretch out casing, apopore is covered as spray head stretches out
Pipe.Flexible spray gun of the invention cooperates hydraulic pressure to carry out automatic telescopic to spray head by elastic component, since apopore is arranged in spray head
Side, do not use spray gun in the state of, casing covers apopore, and apopore is prevented to be dirty.
Sprue is set to move backward closing water passing groove 2. when not in use, spring element applies elastic force to sprue；In use, water
Pressure acts on sprue, and sprue forward movement is gradually opened water passing groove, and due to the effect of sprue, apopore is stretching out sleeve
Before, water can be flowed out by the gap of spray head and casing, to achieve the purpose that automatic cleaning sprayer.Meanwhile the residual in water cavity
Water can the gap at first between spray head and casing spill out.While gap of the water flow between spray head and sleeve is flowed out,
Spray head gradually stretches out casing with apopore in the presence of hydraulic pressure；When spray head fully extended casing, water flow is just complete
It opens.Therefore, flexible spray gun of the invention has the advantages that self-cleaning.
3. spray head stops moving forward when locating piece and card-bit part are pressed against, the mobile excess of stroke of spray head is prevented.
4. spray head auto-extending can be made by opening water passage, and closing water passage can by pressure valve for switching water passage
Retract spray head automatically, it is easy to use.
