The embodiments described in the embodiments are intended to explain the present invention and are not to be construed as limiting the present invention.

[0027] Reference in this specification to "one embodiment," "an example," or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0028] Example 1:

[0029] See also Figure 1-Figure 3 , an adjustable sprinkler, comprising a sprinkler body, the sprinkler body comprising a base 1, a nozzle 2 and a nozzle 3, the base 1 being provided with a nozzle 2, the water spraying end of the nozzle being connected to the nozzle 3; a sleeve 6 being provided on the outer periphery of the nozzle 3, the water spraying end of the nozzle 3 extending out of the sleeve 6; it is characterized in that a plurality of columnar adjusting members 4 are provided on the sleeve 6, and through holes corresponding to the columnar adjusting members 4 are formed on the side walls of the sleeve 6; the columnar adjusting member 4 passes through the through hole and abuts against the outer peripheral wall of the nozzle 3, and the columnar adjusting member 4 can be moved and fixed along the axial direction of the through hole, and the adjusting member 4 is used to adjust the angle of the nozzle 3 relative to the plane where the base 1 is located.

[0030] Specifically, the adjusting member 4 is an adjusting screw, and the through hole is a threaded hole; the external thread of the adjusting screw is adapted to the internal thread of the corresponding threaded hole, and the adjusting screw can move in the axial direction of the threaded hole by rotating in the threaded hole.

[0031] As a preferred embodiment, the number of the adjusting screws is four, the axis of the threaded hole is perpendicular to the axis of the nozzle 2, and the four adjusting screws are evenly spaced along the circumference of the nozzle 2. The threaded hole extends from the outer wall of the sleeve to the inner wall of the sleeve, and the threaded hole is located near the top surface of the sleeve.

[0032] In a preferred embodiment, the tail of the adjusting screw is flat, the nozzle 3 is cylindrical, and the tail of the adjusting screw abuts the outer peripheral wall of the nozzle. In other embodiments, the tail of the adjusting screw is spherical, and the four adjusting screws on the nozzle pipe 2 abut against the outer peripheral surface of the nozzle 3 to achieve stable support.

[0033] When debugging and installing the fountain, first check whether the mounting base is in place, and then start adjusting the angle of the nozzle. The specific operation method is to rotate the four adjustment screws to push the nozzle 3, gradually adjust the nozzle 3 to the correct angle, and then test whether the nozzle is running smoothly and whether the shape and direction of the water flow are accurate. In this embodiment, four adjustment screws are provided around the nozzle, and the direction of the nozzle 3 is adjusted by the adjustment screws. The direction of the nozzle 3 adjusted by the four adjustment screws is more accurate, and basically it can be adjusted during the operation and debugging of the fountain. After the nozzle angle is adjusted normally, the four adjustment screws can provide good support for the nozzle, and no deviation will occur during the subsequent operation of the fountain.

[0034] It should be noted that in this embodiment, the number of the adjusting screws can be four or more, and there is no limitation on the number of the adjusting screws.

[0035] Example 2:

[0036] See also Figure 4-Figure 6 In actual use, if the distance between adjacent nozzles is small, the adjustment space of the adjustment screw of the adjustable nozzle provided in Example 1 is small. In order to improve the above problem, Example 2 is provided. An adjustable nozzle, an adjustable nozzle, comprising a nozzle body, the nozzle body comprising a base 1, a nozzle 2 and a nozzle 3, the base 1 is provided with a nozzle 2, the water spraying end of the nozzle is connected to the nozzle 3; the outer periphery of the nozzle 3 is provided with a sleeve 6, the water spraying end of the nozzle 3 extends out of the sleeve 6; it is characterized in that a plurality of columnar adjustment members 4 are provided on the sleeve 6, and a through hole corresponding to the columnar adjustment member 4 is formed on the side wall of the sleeve 6; the columnar adjustment member 4 passes through the through hole and abuts against the outer peripheral wall of the nozzle 3, and the columnar adjustment member 4 can be moved and fixed along the axial direction of the through hole, and the adjustment member 4 is used to adjust the angle of the nozzle 3 relative to the plane where the base 1 is located.

[0037] Specifically, the adjusting member 4 is an adjusting screw, and the through hole is a threaded hole; the external thread of the adjusting screw is adapted to the internal thread of the corresponding threaded hole, and the adjusting screw can move in the axial direction of the threaded hole by rotating in the threaded hole.

[0038] As a preferred embodiment, Figure 6 As shown, there are three adjusting screws, the axes of the threaded holes are inclined relative to the axis of the nozzle 2, and the three adjusting screws are evenly spaced along the circumference of the nozzle 2. The threaded holes extend from the top surface of the sleeve to the inner wall of the sleeve, facilitating adjustment of the adjusting screws when the distance between adjacent nozzles is small.

[0039] In a preferred embodiment, the tail of the adjusting screw is flat, the nozzle 3 is cylindrical, and the tail of the adjusting screw abuts against the outer peripheral wall of the nozzle. In other embodiments, the tail of the adjusting screw is spherical, and the three adjusting screws on the nozzle pipe 2 abut against the outer peripheral surface of the nozzle 3 to achieve stable support.

[0040] During fountain commissioning and installation, or if the nozzle deflects and requires maintenance, simply rotate the three adjustment screws to gradually adjust the nozzle 3 to the correct angle. Then, test whether the nozzle is operating smoothly and the water flow pattern and direction are accurate. Because the threaded hole extends from the top of the sleeve to the inner wall, adjustments can be made diagonally downward from the top of the nozzle, eliminating the distance between nozzles and giving the operator more room for adjustment.

[0041] It should be noted that, in this embodiment, the number of the adjusting screws can be three or more, and there is no limitation on the number of the adjusting screws.

[0042] It is worth mentioning that different nozzles can be selected according to the overall design of the fountain. For example, when multiple nozzles are closely arranged, that is, when there is narrow adjustment space between adjacent nozzles, three or more adjusting screws tilted relative to the nozzles as described in Example 2 are selected. It is easier for operators to install and fix and adjust the angle position of the nozzle 3, so as to improve the convenience of nozzle debugging and installation or subsequent operation and maintenance. When a single nozzle or multiple nozzles are far apart, four or more adjusting screws perpendicular to the nozzles as described in Example 1 are selected to support the nozzle 3 more stably. The direction of the nozzle 3 adjusted by the screws is more accurate and can basically be adjusted during the operation and debugging of the fountain. After the nozzle angle is adjusted normally, it will no longer deviate during the subsequent operation of the fountain.

[0043] Example 3:

[0044] The adjustable nozzles provided in Examples 1 and 2 have a gap between their sleeves and nozzles. In actual use, some of the water sprayed from the nozzles falls into this gap, defined by the annular groove between the inner wall of the sleeve 6 and the outer wall of the nozzle 3. When this annular groove is full, water overflows, affecting the fountain's backflow. If water from each nozzle were to accumulate in the annular groove, the fountain's bottom would be insufficient.

[0045] To improve the above problem, Example 3 is set. Figures 1-6 Compared with Examples 1 and 2, the adjustable nozzle provided in Example 3 is provided with a sleeve 6 and a nozzle 2 as an integrated structure, and an annular groove is defined between the inner wall of the sleeve 6 and the outer wall of the nozzle 3. A plurality of water outlet holes 5 are formed at the bottom of the side wall of the annular groove, and the plurality of water outlet holes 5 are arranged at intervals along the circumference of the annular groove. The water sprayed by the nozzle 3 falls into the annular groove and is discharged to the bottom of the fountain through the water outlet holes 5. The four water outlet holes 5 are arranged at equal intervals along the circumference of the annular groove, and the water outlet holes 5 are waist-shaped holes or rectangular holes, which facilitate the discharge of water in the annular groove.

[0046] When in use, part of the water sprayed from the nozzle will fall into the annular groove, and the water accumulated in the annular groove will be discharged through the water outlet 5 and fall to the bottom of the fountain, and then the bottom of the fountain will supply water to the nozzle to form a cycle.

[0047] In some embodiments, see Figures 1-6 The base 1 is in the shape of a rectangular plate as a whole, and the nozzle 2 and the nozzle 3 are both columnar. The advantage of the rectangular base 1 is that multiple nozzles can be tightly combined together, thereby reducing the overall volume. A connecting ear plate is provided at each of the four corners of the base 1, and a mounting hole is provided on the connecting ear plate. The connecting ear plate can be used to connect to the bracket of the pumping assembly. A mounting cavity is formed in the center of the base 1, and the nozzle 2 is vertically arranged in the mounting cavity. Four reinforcing ribs are provided between the nozzle 2 and the mounting cavity, and the four reinforcing ribs are arranged at equal intervals along the circumference of the nozzle 2. The base 1, nozzle 2, nozzle 3 and reinforcing ribs are integrally injection molded from plastic material. The plastic nozzle can be widely used in water spraying equipment in various fountains, waterscapes and other places. It has the advantages of light weight, corrosion resistance, good insulation performance, etc. At the same time, the shape and size make the plastic nozzle better adaptable to different fountain shapes and water flow requirements.

[0048] In practical applications, the base 1 , the nozzle 2 and the nozzle 3 may also be connected in other ways, such as welding, threaded connection, etc.

[0049] The utility model has a simple structure and is easy to use. The angle of the nozzle can be adjusted by pushing the nozzle through the adjusting screw against the outer wall of the nozzle. The adjustment method is convenient and intuitive. The operator adjusts the angle of the nozzle to the correct angle according to the design requirements of the fountain, avoiding the situation where the nozzle angle cannot be adjusted before, and improving the convenience of installation, commissioning and later operation and maintenance.

[0050] Example 4:

[0051] A fountain module comprises an adjustable nozzle as in any one of Examples 1-3 and a pumping assembly connected to the water inlet end of the nozzle 2. Specifically, the pumping assembly comprises a bracket, a water pump and a protective shell. The top surface of the bracket is fixedly connected to the base 1. The specific connection method between the bracket and the base 1 is not limited in this embodiment. An installation cavity is formed in the bracket, the water pump is installed in the installation cavity of the bracket, and the water outlet end of the water pump is connected to the water inlet end of the nozzle 2; the protective shell is sleeved on the outside of the water pump and the bracket, and the pumping assembly is generally placed in the water of a river, lake, river, artificial viewing pool, etc. The protective shell is used to protect the pumping assembly, which pumps water from the river, lake, river, artificial viewing pool, transports it to the water inlet end of the nozzle 2, and then sprays it out from the water spraying end of the nozzle 3. In this embodiment, the water inlet end of the water pump is provided with a filter screen or filter cotton, and the filter screen filters larger impurities in the water, such as garbage, fallen leaves, driftwood, etc. Filter cotton can filter out smaller impurities in the water, such as dust, algae, insects, etc.

[0052] In fountain landscaping, multiple fountain modules can be combined in a certain arrangement to achieve a variety of effects. For example, multiple fountain modules can be arranged in a geometric shape, or multiple fountain modules can be arranged in multiple layers, with the nozzle modules on each layer arranged in a ring, to form a waterscape for people to enjoy, meeting the needs of various situations.

[0053] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
