It is logical.The top of first push rod 21 and the bottom end of the second push rod 28 are fixedly connected to buffer unit 31, in the present embodiment, buffer part
Part 31 is rubber pad.First through hole and the second through hole are fixedly connected to waterproof washer 32.
Specific implementation process is as follows: in use, staff holds surge-chamber 6, road surface cleannes situation is observed, according to road
The number of amount of dust adjusts amount of water sprayed on face.When the dust on road surface is less, staff rotates counterclockwise threaded rod 22,
So that the length of the threaded rod 22 in first chamber 19, threaded rod 22 pushes 18 upward sliding of relief piston, is fixedly connected
The first push rod 21 on relief piston 18 moves up.
Meanwhile the volume of second chamber 20 reduces, hydraulic increase, the liquid in second chamber 20 flows into the 4th through pipeline 30
In chamber 27, the liquid of the 4th chamber 27 increases, and 25 slide downward of transformation piston, the second push rod 28 moves down.At this point, first
The distance between push rod 21 and the second push rod 28 reduce.
After the completion of staff adjusts threaded rod 22, water pump is opened, water is pumped into external water pipe by water pump, and water enters tune
It saves in chamber 8, the impact force that when water flowing generates makes overhead gage 4 occur to deflect clockwise, the bottom of overhead gage 4 and the second push rod 28
End offsets, also, lower baffle plate 5 and the top of the first push rod 21 offset at this time, and water can only be by between overhead gage 4 and lower baffle plate 5
Space flow into water outlet hard tube 2 left end.Before no adjusting threaded rod 22, in adjusting cavity 8, overhead gage 4, lower baffle plate
The space left between 5 becomes smaller, and after water flows through adjusting cavity 8, then flows into the amount reduction of the left end of water outlet hard tube 2, realizes on road surface
When dust is less, the water that water pistol sprays is less, realizes the cleaning of road pavement, while avoiding the waste of water resource.
Similarly, when staff has found that the dust on road surface is more, threaded rod 22 is rotated clockwise, so that the first chamber
The length of threaded rod 22 in room 19 shortens, and the liquid in first chamber 19 under the effect of gravity applies downwards relief piston 18
Pressure drive the first push rod 21 to move down so that 18 slide downward of relief piston, lower baffle plate 5 occurs counterclockwise inclined therewith
Turn.
Meanwhile the volume of second chamber 20 increases, the liquid in the 4th chamber 27 flows into second chamber 20 through pipeline 30,
25 upward sliding of transformation piston, the second push rod 28 move up.At this point, the distance between the first push rod 21 and the second push rod 28 increase
Greatly, the space left between overhead gage 4, lower baffle plate 5 becomes larger, and opens water pump, after water flows through adjusting cavity 8, then flows into water outlet hard tube 2
The amount of left end increase, realize when road dust is more, the water that water pistol sprays is more, guarantees road surface is clean.
In the above process, it is notable that staff rotates clockwise threaded rod 22, so that in first chamber 19
The length of threaded rod 22 shortens, and the top of threaded rod 22 moves down, may also although the meeting slide downward of relief piston 18
There are the tops of threaded rod 22 and the discontiguous phenomenon of relief piston 18.Water pistol is discharged however, this phenomenon has no effect on
The adjusting of amount: after opening water pump, when water is flowed into adjusting cavity 8, the impact force that when water flowing generates is applied to overhead gage 4 and lower block
On plate 5, so that overhead gage 4 and the bottom end of the second push rod 28 tightly abut against, the top tightly phase of lower baffle plate 5 and the first push rod 21
It supports, then, the first push rod 21 is moved down by active force, and 18 slide downward of relief piston is until relief piston 18 and threaded rod
22 top offsets, while the second push rod 28 is moved up, 25 upward sliding of transformation piston, the 4th chamber by upward power
Liquid in 27 flows into second chamber 20 through pipeline 30.Therefore, the space left between overhead gage 4 and lower baffle plate 5 becomes larger, water
After flowing through adjusting cavity 8, then flows into the amount of left end of water outlet hard tube 2 and increase.
Water-saving water pistol in the present embodiment, staff only need according to road surface cleannes situation, clockwise or
Rotate counterclockwise threaded rod 22, so that it may amount of water sprayed is adjusted, it is easy to operate, it is low to the operative skill requirement of staff, it is practical
Property is strong, is conducive to promote the use of.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and practicability of the invention.
