Description

Technical Field

[0001] The utility model relates to the field of sprinkler heads, in particular to a sprinkler head for gardening and greening. Background Art

[0002] Gardening sprinklers usually extend a certain distance upward from the ground, and the water sprayed is sprayed all around. There are some problems in the actual use of this solution, because the area where the water is actually sprayed is a circle. If it is a little too far away, it cannot be fully watered, and watering a larger area cannot be achieved. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a watering nozzle for landscaping, which sprays water under the combined rotation of the rotating drum and the rotating head with different rotating axes. The movement of the spray hole relative to the main pipe is very complex, and the surrounding watering coverage is wider and relatively more uniform.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a watering nozzle for landscaping, comprising a main pipe, a rotating drum and a rotating head;

[0005] The upper end of the main pipe is rotatably engaged with the lower end of the rotating drum;

[0006] The interior of the drum is provided with propeller blades;

[0007] The upper end of the rotating drum is sealed, and the upper end side of the rotating drum is radially connected to a diameter pipe;

[0008] The outer end of the diameter tube is rotatably engaged with the rotating head, a water sprinkling channel is provided inside the rotating head, the inner end of the water sprinkling channel is connected to the diameter tube, and a spray hole is provided on the outer wall of the rotating head along the tangential direction, and the spray hole is connected to the outer end of the water sprinkling channel.

[0009] Beneficial effects of the utility model:

[0010] After the water flows out from the main pipe, it enters the drum and then into the diameter pipe, then into the rotating head, and then sprays water from the spray hole onto the ground to irrigate the lawn or other green plants on the ground.

[0011] Since propeller blades are provided inside the drum, the water flow will drive the drum to rotate as a whole, that is, the drum can rotate in the horizontal plane. At the same time, since water is sprayed from the nozzles set at the tangent, the rotating head will continue to rotate under the reaction force of the water sprayed from the nozzles. When the nozzles are facing downward, the water can water the nearby green plants. When the nozzles are facing obliquely upward, the water can water the green plants at a farther distance.

[0012] The entire water spray is sprayed out under the combined rotation of the drum and the rotating head with different rotating axes. The movement of the spray hole relative to the main pipe is very complex, and the surrounding watering coverage is wider and relatively more uniform.

[0013] Preferably, the lower end of the rotating drum is externally mounted on the upper end of the main pipe, an annular upper limit stop is provided outwardly from the upper end of the main pipe, and an annular lower limit stop is provided inwardly from the lower end of the rotating drum. A plane bearing is provided between the upper and lower limit stops, and a lower positioning ring is provided on the main pipe below the lower limit stop. This can define the relative position of the rotating drum and the main pipe to prevent them from separating, and the plane bearing can facilitate the rotation of the rotating drum.

[0014] Preferably, a fastening screw is provided on the side wall of the lower positioning ring, and the front end of the fastening screw abuts against the outer wall of the main pipe. The lower positioning ring can limit the position of the rotating drum moving downward, and the fastening screw makes it very simple to assemble.

[0015] Preferably, the upper end surface of the lower positioning ring is a sloped structure with a high inner side and a low outer side. In this solution, the rotating drum and the main pipe are not sealed together. There is a certain gap between them, and water can flow out from the gap. The outflowing water hits the sloped structure downward and splashes around the main pipe, thereby preventing excessive water from flowing under the main pipe.

[0016] Preferably, the rotating drum includes a barrel and a pulp barrel, the upper section of the barrel is provided with the diameter tube, the lower section of the barrel is rotatably matched with the main tube, the inner wall of the middle section of the barrel is provided with an inner spline section, the outer wall of the pulp barrel is provided with an outer spline adapted to the inner spline section, and the propeller blades are provided on the inner wall of the pulp barrel. The propeller blades are provided separately in the pulp barrel, which is easier to process and simpler to assemble.

[0017] Preferably, the outer end of the diameter tube is sealed, and a plurality of water outlets are disposed around the outer sidewall of the diameter tube. The rotating head is disposed around the outer periphery of the water outlets, and an inner cavity is disposed around the inner wall of the rotating head corresponding to the water outlets. The inner cavity is connected to the spray holes through the water sprinkling passage. This ensures that the rotating head can rotate more easily relative to the diameter tube, and that sufficient water can be sprayed from the spray holes regardless of the angle to which the rotating head is rotated.

[0023] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1 As shown, a watering nozzle for landscaping includes a main pipe 1, a rotating drum and a rotating head 4;

[0026] The upper end of the main pipe 1 is rotatably matched with the lower end of the rotating drum;

[0027] The interior of the drum is provided with propeller blades 7;

[0028] The upper end of the drum is sealed, and the upper end side of the drum is radially connected to a diameter pipe 3;

[0029] The outer end of the diameter tube 3 is rotatably matched with the rotating head 4, and a water sprinkling channel is provided inside the rotating head 4. The inner end of the water sprinkling channel is communicated with the diameter tube 3. Figure 2 As shown, a spray hole 8 is provided on the outer wall of the rotating head 4 along the tangential direction, and the spray hole 8 is communicated with the outer end of the water sprinkling channel.

[0030] Beneficial effects of the utility model:

[0031] After flowing out of the main pipe 1, the water flows into the drum, continues to enter the diameter pipe 3, enters the rotating head 4, and then sprays water from the spray hole 8 onto the ground to irrigate the lawn or other green plants on the ground.

[0032] Since propeller blades 7 are provided inside the drum, the water flow will drive the drum to rotate as a whole, that is, the drum can rotate in the horizontal plane. At the same time, since water is sprayed from the spray holes 8 set at the tangent, the rotating head 4 will continue to rotate under the reaction force of the water sprayed from the spray holes 8. When the spray holes 8 are facing downward, the water can water the nearby green plants. When the spray holes 8 are facing obliquely upward, the water can water the green plants at a farther distance.

[0033] The entire water spray is sprayed under the combined rotation of the drum and the rotating head 4 with different rotating axes. The movement of the spray hole 8 relative to the main pipe 1 is very complex, and its coverage of the surrounding glue is wider and relatively more uniform.

[0034] The lower end of the rotating drum is fitted over the upper end of the main pipe 1. An annular upper limit stop is provided outward from the upper end of the main pipe 1, while an annular lower limit stop is provided inward from the lower end of the rotating drum. A plane bearing is provided between the upper and lower limit stops. A lower positioning ring 5 is fitted over the main pipe 1 below the lower limit stop. This helps to define the relative position of the rotating drum and the main pipe 1, preventing them from separating. Furthermore, the plane bearing facilitates the rotation of the rotating drum.

[0035] The side wall of the lower positioning ring 5 is provided with a fastening screw, and the front end of the fastening screw abuts against the outer wall of the main pipe 1. The lower positioning ring 5 can limit the position of the downward movement of the drum, and the fastening screw makes it very simple to assemble.

[0036] The upper end surface of the lower positioning ring 5 is a slanted structure with a high inner side and a low outer side. In this solution, the rotating drum and the main pipe 1 are not sealed together. There is a certain gap between them, and water can flow out from the gap. The water flows down and hits the slanted structure and splashes around the main pipe 1, preventing excessive water from flowing under the main pipe 1.

[0037] Combine Figure 3 As shown, the rotating drum includes a barrel 2 and a pulp barrel 6. The upper section of the barrel 2 is provided with the diameter tube 3, and the lower section of the barrel 2 is rotatably matched with the main pipe 1. The inner wall of the middle section of the barrel 2 is provided with an internal spline section, and the outer wall of the pulp barrel 6 is provided with an external spline adapted to the internal spline section. The propeller blade 7 is provided on the inner wall of the pulp barrel 6. The propeller blade 7 is provided separately on the pulp barrel 6, which is easier to process and simple to assemble. The pulp barrel 6 and the propeller blade 7 are integrally formed by 3D printing.

[0038] The outer end of the diameter tube 3 is sealed, and the outer side wall of the diameter tube 3 is surrounded by a plurality of water outlets. The rotating head 4 is sleeved around the outer periphery of the water outlets. The inner wall of the rotating head 4 is surrounded by an inner cavity corresponding to the water outlets. The inner cavity is connected to the spray hole 8 through the water sprinkling. This ensures that the rotating head 4 can rotate more easily relative to the diameter tube 3, and no matter what angle the rotating head 4 is rotated to, sufficient water can be sprayed from the spray hole 8.

[0039] If it is desired to increase the spacing between the drum and the main pipe 1, the diameter pipe 3 and the rotary head 4, a sealing ring may be provided.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
