Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiments are only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
Embodiment one
As shown in Fig. 1 to 7, a kind of high-pressure cleaning device, can prevent outlet from dripping, and the mode for realizing this purpose is to employ
A kind of antidrip high-low pressure combination nozzle, the combination nozzle include：High pressure nozzle（3）, it has a center spray road（302）, it is sliding
Dynamic valve（6）, it has a water hole（605）, head capsule（1）, it has one and penetrates through its front and back end to house the high pressure nozzle
（3）With the slide-valve（6）Cavity；Low-pressure nozzle（2）, it has center spray road described in a center face（302）Master go out
The mouth of a river（201）Be arranged at the main water outlet（201）At least one auxiliary water outlet of side（202）, and spring（4）.Institute
State slide-valve（6）It is slidably disposed in the high pressure nozzle（3）Rear；The slide-valve（6）Outer wall and the cavity
Cavity wall formed be slidingly sealed, the high pressure nozzle（3）Outer wall and the cavity cavity wall between form a bypass path
（101）, the slide-valve（6）Relatively described high pressure nozzle（3）It can make the bypass path when mobile（101）With the center
Spray road（302）It is connected or mutually closes.The low-pressure nozzle（2）It is slidably disposed in the head capsule（1）Cavity in and with
The head capsule（1）Formation is slidingly sealed, the low-pressure nozzle（2）Positioned at the high pressure nozzle（3）Front, the spring（4）
Positioned at the head capsule（1）Cavity in and abut the low-pressure nozzle（2）With the head capsule（1）, the low-pressure nozzle（2）
Can be with the high pressure nozzle（3）Contact forms sealing；The auxiliary water outlet（202）With the bypass path（101）It is connected.
The low-pressure nozzle 2 set by activity so that in the initial stage that high pressure is changed to low pressure, pass through bypass path
101 flow to current at low-pressure nozzle 2 and hydraulic pressure is smaller, and water, which flows through auxiliary water outlet 202 and forms shallow bid current, at this time outwards sprays
Go out, this strand of current finally rush at front so as to avoid it from directly dropping onto ground by the higher current of the pressure that water outlet 301 sprays
Face and the normal use for influencing equipment.When the current for flowing through bypass path 101 gradually increase, it gradually pushes away low-pressure nozzle 2
Forwards so that 2 rear end of low-pressure nozzle is connected with bypass path 101, current can directly pass through the master of low-pressure nozzle 2 at this time
Water outlet 201 sprays.
As a kind of typical high-low pressure conversion regime, the front end of slide-valve 6 has one can be formed with inner cylinder face 303
The external cylindrical surface 606 being slidingly sealed, external cylindrical surface 606 are equipped with least one axial cross section and accumulate linear or proximal line from the front to the back
Property becomes larger and extends to the dredging flow groove 601 of 606 front end of external cylindrical surface.As a typical structure, dredging flow groove 601 along parallel to
The direction extension of external cylindrical surface 606 forms.When 6 relatively high pressure nozzle 3 of slide-valve slides, bypass path is flowed into from water hole 605
101 water flow linearly changes to be converted so as to fulfill high-low pressure.

The water outlet direction place of intersecting is located at the inside of head capsule 1.
As shown in Figures 4 and 5, when the front end of slide-valve 6 extend into the bosom in center spray road 302 of high pressure nozzle 3, this
When dredging flow groove 601 completely enclosed by inner cylinder face 303, current are directly over water hole 605 and center spray road 302 from high pressure at this time
The front end of nozzle 3 sprays, and combines nozzle at this time and is in the state that sprays water with high pressure.
As shown in fig. 6, when slide-valve 6 is gradually moved rearwards the rearmost end for making the rear end of high pressure nozzle 3 exceed dredging flow groove 601
When, the rear end in center spray road 302 is connected by dredging flow groove 601 with bypass path 101, at this time the water in water hole 605 start through
Shunted by bypass path 101 so that inside water pressure diminishes, with gradual exposed, more water entrance bypass of dredging flow groove 601
In path 101, nozzle is combined at this time and is in high pressure to low pressure transition status.
As shown in fig. 7, when the front end of slide-valve 6 completely disengages high pressure nozzle 3, the rear end in the road of center spray at this time 302 is complete
It is full unblocked, nozzle is combined at this time is in low pressure water spray state.
As shown in figure 15, due to the axial cross section of dredging flow groove 601 occur with the movement of slide-valve 6 it is linear or close to line
Property change, therefore make hydraulic pressure also linear or close to linear transformation, so as to be unlikely to larger pressure oscillation occur.
