Description

Technical Field

[0001] The invention belongs to the technical field of nozzles, and in particular relates to a universal nozzle. Background Art

[0002] A universal sprinkler is a device that can flexibly adjust the spray direction. Its most notable feature is its flexible connection structure, such as a common ball joint, which allows the nozzle to be adjusted in multiple directions. Vertical adjustment is generally up to ±15 degrees, and the jet axis can also be adjusted by ±10 degrees. Types include universal concentrator direct-spray sprinklers, adjustable direct current sprinklers, and adjustable cannon sprinklers. Universal sprinklers have a wide range of applications.

[0003] In existing omnidirectional sprinkler applications, traditional omnidirectional sprinklers typically only have the function of adjusting the nozzle's direction. During the adjustment process, the internal filter components cannot be maintained. After long-term use, the filter components are prone to clogging due to impurity accumulation, affecting the nozzle's water output and service life. Furthermore, traditional omnidirectional sprinklers lack an effective fixing structure after adjusting the nozzle's direction, making it prone to displacement due to external forces and collisions, making it impossible to stably maintain the desired spray direction. Therefore, a omnidirectional sprinkler was proposed. Summary of the Invention

[0034] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example 1: Figure 1 - Figure 9 As shown, a universal sprinkler includes a sprinkler 1, a U-shaped frame 2, a shield 12 and a tee pipe 11: the tee pipe 11 is rotatably mounted on the U-shaped frame 2, the shield 12 is fixedly mounted on the U-shaped frame 2, a notch is provided on the shield 12, the sprinkler 1 is fixedly connected to the tee pipe 11, a tee pipe 2 5 is mounted on the U-shaped frame 2, the tee pipe 2 5 is connected to the tee pipe 11, both ends of the tee pipe 2 5 are fixedly passed through the U-shaped frame 2, a rotating joint 2 6 is rotatably connected to the tee pipe 2 5, and the rotating joint 2 6 is connected to the water source A tooth protrusion 61 is provided on the rotating joint 2 6, and a through opening 21 is opened on the U-shaped frame 2. The rotating joint 2 6 is rotatably set in the through opening 21. Such a structural design enables the nozzle 1 to be flexibly rotated on the U-shaped frame 2 through the three-way pipe 11, thereby realizing multi-angle adjustment of the water spray direction; the three-way pipe 2 5 is connected with the three-way pipe 11 and cooperates with the rotating joint 2 6, ensuring that the water flow can be smoothly introduced into the nozzle 1, and the through opening 21 provides a stable rotation space for the rotating joint 2 6, thereby improving the stability and reliability of the overall structure.

[0036] like Figure 4 - Figure 5As shown, a fixed pipe group 3 is provided between the tee pipe 2 5 and the tee pipe 1 11, and the fixed pipe group 3 includes an inlet pipe 31 and a backwash pipe 32. A rotating joint 111 is fixedly provided at both ends of the tee pipe 11. The inlet pipe 31 and the backwash pipe 32 are respectively rotatably provided on the rotating joint 111. The inlet pipe 31 is connected with an inlet branch pipe 311 and a sewage branch pipe 312. The sewage branch pipe 312 is staggered with the inlet branch pipe 311. The backwash pipe 32 is connected with a backwash branch pipe 321. A connecting elbow 51 is provided at both ends of the tee pipe 2 5. The tee pipe The second 5 is connected to the water inlet branch pipe 311 and the backwash branch pipe 321 respectively through the connecting elbow 51. The existence of the fixed pipe group 3 provides the basis for the water flow diversion and backwashing functions. The water inlet pipe 31 and the backwash pipe 32 are rotatably connected to the tee pipe 11 through the rotating joint 111, which does not affect the rotation adjustment of the tee pipe 11. The reasonable layout of the water inlet branch pipe 311, the sewage branch pipe 312 and the backwash branch pipe 321, combined with the connecting elbow 51, enables the normal water supply, sewage discharge and backwashing cleaning functions to be realized in an orderly manner, effectively improving the functionality and practicality of the nozzle.

[0037] like Figure 4 - Figure 6 As shown, a regulating tube group 4 is slidingly provided on the fixed tube group 3. By pressing the regulating tube group 4, the connection state of the regulating tube group 4 and the fixed tube group 3 is changed. The regulating tube group 4 includes a sliding tube 1 41 and a sliding tube 2 42. The sliding tube 1 41 and the sliding tube 2 42 are respectively sealed and slidably provided in the water inlet pipe 31 and the backwash pipe 32. A limiting plate 43 is fixedly provided on the sliding tube 1 41 and the sliding tube 2 42. A spring 44 is fixedly provided between the limiting plates 43. The spring 44 is sleeved on the sliding tube 1 41 and the sliding tube 2 42. A filter plate 45 is fixedly provided in the sliding tube 1 41. A water inlet 2 421 is provided on the sliding tube 2 42. After the sliding tube 2 42 is pressed and moved, the backwash branch pipe 321 is connected to the sliding tube 2 42 through the water inlet 2 421. There are a water inlet 411 and a sewage outlet 412. The water inlet branch pipe 311 is connected to the sliding pipe 1 41 through the water inlet 1 411. After the sliding pipe 1 41 is pressed and moved, the sewage branch pipe 312 is connected to the sliding pipe 1 41 through the sewage outlet 412. The regulating pipe group 4 realizes the switching of different working states through the sliding pipe 1 41 and the sliding pipe 2 42 on the fixed pipe group 3; the setting of the spring 44 and the limit plate 43 ensures that the sliding pipe 1 41 and the sliding pipe 2 42 can be stably reset when not subject to external force; the filter plate 45 can filter the water flow, and by changing the connection state of the water inlet 1 411, the water inlet 2 421, the sewage outlet 412 and the corresponding branch pipes, the backwash cleaning function can be conveniently realized, effectively preventing the filter plate 45 from being blocked and extending the service life of the nozzle.

[0038] like Figure 3 - Figure 4As shown, a limiting gear set 7 is provided on the three-way pipe 11, and the limiting gear set 7 includes a gear A71 and a gear B72. The gear A71 is rotatably set at both ends of the three-way pipe 5, and the gear B72 is fixedly set at both ends of the three-way pipe 11. The gear B72 is engaged with the gear A71. When the nozzle 1 is adjusted to a suitable angle, the rotation of the three-way pipe 11 can be limited by limiting the rotation of the gear A71, thereby stably fixing the nozzle 1 in the set position, avoiding the deviation of the nozzle 1 due to external force collision and other factors, and ensuring the stability and accuracy of the nozzle when in use.

[0039] like Figure 3 and Figure 7 As shown, a handle 8 is slidingly provided on the U-shaped frame 2, and mounting rods 81 are provided at both ends of the handle 8. The mounting rod 81 is slidingly provided on the U-shaped frame 2. A slide groove 811 is opened on the U-shaped frame 2, and the mounting rod 81 is slidingly provided on the U-shaped frame 2 through the slide groove 811. A ring 82 is provided between the mounting rods 81, and the ring 82 is sleeved on the rotating joint 6. The combination of the handle 8, the mounting rod 81 and the slide groove 811 provides the operator with a convenient operating component, making the adjustment process smoother. At the same time, the slide groove 811 and the ring 82 also play a certain limiting and guiding role, thereby improving the convenience of operation and the coordination of the structure.

[0040] like Figure 3 and Figure 7 As shown, a limiting plate 9 is slidingly provided on the U-shaped frame 2, and the limiting plate 9 limits the movement of the limiting gear group 7 and the rotating joint 2 6. The limiting plate 9 is fixedly set on the mounting rod 81, and an inclined groove 91 is opened on the limiting plate 9. A protrusion 92 is provided on the limiting plate 9, which can be embedded between the tooth protrusions 61. The limiting plate 9 can be embedded between the tooth grooves of the gear A71. The limiting plate 9 cooperates with the tooth protrusions 61 on the limiting gear group 7 and the rotating joint 2 6 to achieve the dual functions of rotating and fixing the nozzle 1. At the same time, the edges of the limiting plate 9 and the protrusion 92 are rounded to facilitate the limiting plate 9 and the protrusion 92 to enter the tooth groove of the gear A71 and between adjacent tooth protrusions 61.

[0041] like Figure 3 and Figure 8As shown, a pull rod 10 is slidably provided on the U-shaped frame 2, and the control tube group 4 and the limiting plate 9 are synchronized by the pull rod 10. A through groove 104 is provided on the U-shaped frame 2, and the pull rod 10 is slidably provided in the through groove 104. An avoidance groove 101 is provided on the pull rod 10, and the pull rod 10 is slidably provided on the limiting plate 9 through the avoidance groove 101. A roller 102 is rotatably provided in the avoidance groove 101, and the roller 102 is rollingly provided in the inclined groove 91. The roller 102 can move smoothly in the inclined groove 91, and the pull rod 10 is fixedly connected to the sliding tube 1 41 and the sliding tube 2 42 through the connecting plate 103 respectively. The pull rod 10 plays a key linkage role in the entire structure. It cooperates with the inclined groove 91 and the roller 102 on the limiting plate 9 to convert the movement of the limiting plate 9 into an extrusion action on the regulating tube group 4, thereby realizing the automatic cleaning of the filter plate 45 during the adjustment process of the nozzle 1; the through groove 104 provides a sliding track for the pull rod 10, ensuring the stability and accuracy of its movement, making the entire linkage process smoother and more reliable.

[0042] It should be noted that when the direction of the nozzle 1 needs to be adjusted, the operator pulls down on the handle 8, and the mounting rods 81 at both ends of the handle 8 slide downward along the slide grooves 811 on the U-shaped frame 2, thereby driving the limiting plate 9 fixed to the mounting rods 81 to move downward. The protrusion 92 on the limiting plate 9 disengages from the tooth protrusion 61 on the rotating joint 2 6, and the limiting plate 9 is separated from the gear A71. This allows the previously restricted tee pipe 11 to rotate freely on the U-shaped frame 2, and the rotating joint 2 6 can also rotate flexibly on the tee pipe 2 5. Because the nozzle 1 is fixedly connected to the tee pipe 11, the direction of the nozzle 1 can be adjusted by rotating the tee pipe 11.

[0043] During the downward movement of the limiting plate 9, the inclined groove 91 on the limiting plate 9 interacts with the roller 102 in the avoidance groove 101 on the pull rod 10, driving the pull rod 10 to slide inward along the through groove 104 on the U-shaped frame 2. The pull rod 10 is connected to the sliding tube 1 41 and the sliding tube 2 42 respectively through the connecting plate 103, so that the movement of the pull rod 10 will squeeze the sliding tube 1 41 and the sliding tube 2 42; the sliding tube 1 41 and the sliding tube 2 42 are respectively sealed and slidably arranged in the water inlet pipe 31 and the backwash pipe 32, and a spring 44 is provided between the two; under the squeezing of the pull rod 10, the sliding tube 1 41 and the sliding tube 2 42 overcome the elastic force of the spring 44 to connect with each other, and the originally connected water inlet 1 411 is separated from the water inlet branch pipe 311 and blocked. , and the second water inlet 421 is connected to the backwash branch pipe 321, and the sewage outlet 412 is connected to the sewage branch pipe 312; at this time, the water flows from the second tee pipe 5, passes through the connecting elbow 51 and the backwash branch pipe 321, enters the second sliding pipe 42 through the second water inlet 421, and then flows into the first sliding pipe 41, reversely flushing the filter plate 45 fixed in the first sliding pipe 41, and the sewage after flushing is discharged from the sewage outlet 412 and the sewage branch pipe 312, thereby completing the cleaning of the filter plate 45 in the process of adjusting the direction of the nozzle 1.

[0044] When the nozzle 1 is adjusted to the desired direction, release the handle 8. Under the elastic action of the spring 44, the sliding tube 1 41 and the sliding tube 2 42 return to their original positions. At the same time, the pull rod 10 drives the limiting plate 9 to move upward and reset. The limiting plate 9 again cooperates with the gear A71 and the tooth protrusion 61 to limit the movement of the gear A71 and the rotating joint 2 6, thereby fixing the direction of the nozzle 1. At this time, the backwash branch 321 is separated from the water inlet 2 421, and the water inlet 1 411 is reconnected with the water inlet branch 311. The water flows from the water inlet branch 311 through the water inlet 1 411 into the sliding tube 1 41, and after being filtered by the filter plate 45, it flows to the nozzle 1, resuming its normal water spraying working state. The entire process realizes the linkage operation of the nozzle direction adjustment and the filter plate cleaning, improving the practicality and convenience of the universal nozzle.

[0045] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
