Abstract
The utility model discloses a changeable fountain sprinkler head of water column thickness, its technical scheme main points are, include the first nozzle of big end down's hollow round platform form setting, first nozzle top an organic whole is connected with the transition portion that is the hollow cylinder form and sets up, and the threaded connection of transition portion has the second nozzle, and the discharge area of second nozzle is less than the discharge area of first nozzle, and just first nozzle is provided with the sealing mechanism who prevents the water logging hourglass with second nozzle junction. The utility model aims at providing a changeable fountain sprinkler head of water column thickness can freely change the discharge area of nozzle, and then alternaties the thickness condition of water column, and the flexibility is higher.
Description
Technical field
The utility model relates to the variable fountain nozzle of a kind of water column thickness.
Background technology
As everyone knows, fountain can the air of wetted perimeter, reduces dust, reduces temperature, and the molecules strike in the tiny globule of fountain ejection and surrounding air can produce negative oxygen ion.Therefore, people can build fountain on gardens or square, utilize fountain to spray the fountain view of various moulding, the spray sprayed by fountain, beautify the environment, improve ambient air quality.
Fountain is in course of injection, and the water column situation of formation is relevant with the discharge area of nozzle, and when exit area of nozzle is less, water column is thinner, the range of continuous segment is not high, and water column is dispersed too early, when exit area of nozzle is larger, water column is comparatively thick, and range is higher, but required flow is larger.At present, the fountain nozzle on market, its exit area of nozzle is all changeless, and the water column thickness therefore formed is also unadjustable, and flexibility is poor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the fountain nozzle providing a kind of water column thickness variable, freely can change the discharge area of nozzle, and then the thickness situation of conversion water column, and flexibility is higher.
For achieving the above object, the utility model provides following technical scheme: the fountain nozzle that a kind of water column thickness is variable, comprise the first jet that up-small and down-big shaped hollow round table is arranged, described first jet top is connected with the transition part arranged in hollow cylinder shape, described transition part has been threaded second nozzle, the discharge area of described second nozzle is less than the discharge area of described first jet, and described first jet and second nozzle junction are provided with the sealing mechanism preventing seepage.
Preferably, described sealing mechanism comprises the hollow lug boss and O type circle that are integrally connected to described second nozzle bottom, described transition part is provided with internal thread, described hollow lug boss is provided with the external screw thread cooperatively interacted with it, described transition part endoporus is provided with chamfering, described chamfering and described second nozzle Formation cross-section are leg-of-mutton confined space, and described O type circle is positioned at described seal cavity and conflicts mutually with chamfering and second nozzle.
Preferably, the external diameter of described second nozzle bottom is identical with described transition part external diameter.
Preferably, described first jet and second nozzle outer surface are provided with plastic coating.
This technical scheme compared with prior art has: be threaded above first jet the second nozzle less than its discharge area, and can free installing/dismounting, and then the discharge area changing nozzle changes the thickness of water column, and flexibility is higher.

In figure: 1, first jet; 2, second nozzle; 3, sealing mechanism; 11, transition part; 31, hollow lug boss; 32, O type circle; 111, internal thread; 112 chamferings; 311, external screw thread.
Detailed description of the invention
The fountain nozzle embodiment variable to a kind of water column of the utility model thickness referring to figs. 1 through Fig. 3 is described further.
As shown in Figure 1, the transition part 11(cylinder that first jet 1 top is connected with hollow cylinder shape can make threaded engagement convenient), be used for being threaded with second nozzle 2, second nozzle 2 discharge area is less than first jet 1, when wishing that water column is comparatively thick and then increase range, unload second nozzle 2, when wishing water column comparatively details being about flow, first jet 1 is threaded with second nozzle 2, reduce discharge area, and first jet 1 and second nozzle 2 junction are provided with sealing mechanism 3, seepage can be there is by anti-sealing from junction, flow loses.
Further, as shown in Figures 2 and 3, described sealing mechanism 3 comprises the hollow lug boss 31 and O type circle 32 that are integrally connected to described second nozzle 2 bottom, described transition part 11 is provided with internal thread 111, described hollow lug boss 31 is provided with the external screw thread 311 cooperatively interacted with it, described transition part 11 endoporus is provided with chamfering 112, described chamfering 112 is leg-of-mutton confined space with described second nozzle 2 Formation cross-section, and described O type circle 32 is positioned at described seal cavity and conflicts mutually with chamfering 112 and second nozzle 2.By adopting technique scheme, it is leg-of-mutton confined space that O type circle 32 is arranged in cross section, make O type circle 32 in the state of compression, conflict mutually in O type circle 32 and adjacent three faces, contact area is larger, second nozzle 2 and transition part 11 is impelled to fit together more closely, make sealing effectiveness better, and due to the special position of sealing ring, be placed in inside configuration completely, thus avoid the effect of ultraviolet irradiation and rainwater, prevent sealing ring generation natural aging, make sealing ring permanently effective play sealing function.
Further, the external diameter of described second nozzle 2 bottom is identical with described transition part 11 external diameter.By adopting technique scheme, can make second nozzle 2 and transition part 11 transition better, profile is more attractive in appearance.
Further, described first jet 1 is provided with plastic coating with second nozzle 2 outer surface, can make shower nozzle resistance to chemical attack more.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
