Description
Technical field
The present invention relates to a kind of rainers, and in particular to a kind of water injector.
Background technique
Garden lawn can be used for beautifying the environment, applied widely, and the existing general area coverage of garden lawn is big, just
It needs often to carry out water spray maintenance to it, especially during the broiling summer, regular water spray is even more needed to safeguard.Existing spray
Water maintenance work is generally divided into artificial watering and carries out automatic water jetting in installation sprinkler tip, in order to make the water spray model of sprinkler tip
It encloses more extensively, usual sprinkler tip includes water injector and rotating device, and rotating device mentions while water injector water spray for it
For the power of rotation, rotation that can be 360 °.But rotary device structure is complicated, is easy to happen failure damage, so that spray
Water installations can not rotate, and not be able to satisfy water spray maintenance work.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problems to be solved by the present invention are: how to provide a kind of structure letter
It is single, it can be to 360 ° of water injectors sprayed water around.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:
A kind of water injector, including water pipe, the outlet end of water pipe are fixedly connected with expansion pipe, and expansion pipe is what diameter was gradually increased
The reducer pipe and internal diameter of its smaller diameter end is consistent with water pipe internal diameter, the smaller diameter end for expanding pipe is fixedly connected on the outlet end of water pipe
And coaxially setting, the outlet end of water pipe are provided with spray head, spray head is integrally in conical structure, and the tapered end of spray head is inserted into
In expansion pipe and the center line of spray head and the center line of expansion pipe are coaxial, are fixedly connected on the tapered end of spray head with spray head in
The shaft of heart line setting, shaft are inserted into water pipe, limiting bracket are provided in water pipe and is fixedly connected with pipe inner wall, shaft
It is rotatably assorted across in limiting bracket and with it, limiting device is installed on shaft and the body of rod being located at below limiting bracket, when
When limiting device is connected to the lower surface of limiting bracket, clearance fit between the tapered surface of spray head and the inner wall for expanding pipe.
In the present invention, water flow flows in water pipe, in the outlet end of water pipe, by the tapered surface and expansion pipe of spray head
Gap between wall surface sprays, and the outlet end in this corresponding gap is in the structure expanded outwardly, therefore water flow can be simultaneously
It sprays water towards 360 ° of ranges of surrounding.In addition the spray head of conical structure and the expansion pipe of variable-diameter structure can guide water flow equal
Even ejection.Water flow can apply an outside active force to spray head during ejection, and limiting device is then to spray head
It is limited, make spray head and expands the gap for remaining water spray between pipe, this structure is simple, is hardly damaged, using simple
Reliably.
As optimization, be arranged with the fixing sleeve being firmly connected with it on the shaft of the shaft, with the set of fixing sleeve around
The axle center line uniform intervals are fixedly connected with multi-disc rotating vane, around the spray head center line on the bottom surface of the spray head
Be evenly spaced on it is multiple can be towards the nozzles that spray water on the outside of the spray head, around described on the tapered surface of the spray head
Multiple corresponding with nozzle and connection water inlet flow channel is distributed in spray head center line, and the one end of water inlet flow channel far from nozzle is along the spray
Projection on head centerline direction is located at the water pipe inner hole along the projection on its centerline direction.Water flow direction in water pipe
The Outlet-side flow of water pipe, when by rotating vane, by rotating vane drive shaft rotated, while water flow in addition to
It being sprayed by gap outer, additionally it is possible to water inlet flow channel outflow is sprayed finally by nozzle, since water flow drives spray head rotation,
360 ° of coverage area can also be reached by the water flow that nozzle sprays, the water flow and pass through gap ejection that such nozzle sprays
Water flow is formed upper layer and lower layer water spray layer, increases spray field.
As optimization, the water inlet flow channel includes the sluice way helically risen centered on the spray head center line, is drawn
