[0002] Garden irrigation often uses irrigation nozzles, which discharge water from the liquid outlet pipe by the water pump. When irrigating a far position, a higher water flow pressure is needed to ensure that the water flow can reach a far distance, and the sprayed water droplets need to be larger so that the water droplets can fly farther. When irrigating a near position, a smaller water flow pressure is needed to avoid strong water flow from causing soil erosion or plant damage, and the sprayed water droplets need to be smaller to reduce the impact of the water droplets on the soil.
[0003] In the prior art, the angle of the liquid outlet pipe is generally fixed and cannot be adjusted, but in actual irrigation, there are situations where a far position needs to be irrigated, and there are also situations where a near position needs to be irrigated.

[0011] The pipe body is provided with a sliding groove, and the sliding column is fixedly connected with a sliding strip, and the sliding strip is in sliding cooperation with the sliding groove.
[0012] The pipe body and the sliding column are provided with a sealing ring, the sealing ring is fixedly connected with the sliding column, and the outer side of the sealing ring is attached to the inner wall of the pipe body.
[0013] The pipe body is provided with a limiting ring, and the limiting ring is located on the side, away from the sliding column, of the liquid passage.
[0014] The pipe body is provided with a thread on the end, away from the sliding column.
[0015] The technical effects achieved by the utility model are as follows:

[0025] It should be noted that the end of the pipe body 21 away from the slide column 23 is provided with a water pump (not shown in the figure), the output end of the water pump is communicated with the pipe body 21 through a water pipe (not shown in the figure), the input end of the water pump is communicated with a water tank (not shown in the figure), in the utility model, the output pressure of the water pump is preferably adjustable, the water pump monitors the water pressure in real time through the built-in pressure sensor, compares the detection value with the preset target value by the built-in control unit (such as PLC), and automatically adjusts in two directions (increases or reduces the pressure) according to the real-time pressure deviation, when the pressure needs to be increased, the output pressure is increased by increasing the rotating speed of the water pump motor through the frequency converter, when the pressure needs to be reduced, the rotating speed is reduced or the pressure is reduced through the linkage pressure relief valve, forming a closed-loop control, according to the actual situation on site, the control unit is loaded with a preset pressure target value before irrigation to realize automatic unattended operation, avoiding the case of manual adjustment by workers, the water pump adjusts the output pressure, which is a mature technology, and will not be described here, one end of the spring 24 is fixedly connected with the end of the pipe body 21 away from the liquid passage 211, the other end of the spring 24 is fixedly connected with the frame body 10, the inside of the multi-orifice plate 31 is attached to the end of the liquid outlet pipe 221, the aperture size of the water outlet 311 close to the upper end of the multi-orifice plate 31 is larger than that of the water outlet 311 close to the lower end of the multi-orifice plate 31, in the initial state, the slide column 23 shields the liquid passage 211, and the liquid outlet pipe 221 is inclined upward along the horizontal plane at a small angle.
[0026] It should be noted that the number of the perforated plate 31 is designed, the number of the water outlet hole 311 near the upper end of the perforated plate 31 is less than the number of the water outlet hole 311 near the lower end of the perforated plate 31, so that the number of the water outlet hole 311 near the upper end is less but the aperture size is larger, and the number of the water outlet hole 311 near the lower end is more but the aperture size is smaller, so that when the outlet pipe 221 rotates to the upper end or the lower end, the total area of the water outlet remains the same, the difference is that the water outlet area is different when the water passes through a single water outlet hole 311, which is used to reduce the influence of the water outlet hole 311 with different aperture sizes on the water pressure.
[0027] In this embodiment, water enters the pipe body 21 through the end of the pipe body 21 away from the slide column 23, the water pushes the slide column 23 to move to the end close to the spring 24, so that the gap between the end of the slide column 23 away from the spring 24 and the liquid inlet 211 increases, the water enters the inside of the shell 22 through the gap, and is discharged through the outlet pipe 221, in this process, the shell 22 rotates after the slide column 23 moves, the shell 22 drives the outlet pipe 221 to rotate, so as to adjust the angle of the outlet pipe 221, when the water flow pushing force and the spring 24 elastic force remain balanced, the slide column 23 is in a static state, so that the angle position of the outlet pipe 221 remains fixed, when the far position needs to be irrigated, the water pump works to increase the water pressure, the water pushes the slide column 23 to move to the end close to the spring 24, so that the shell 22 drives the outlet pipe 221 to rotate upward, increasing the angle of the outlet pipe 221 inclined upward along the horizontal plane, facilitating irrigation of the far position, when the near position needs to be irrigated, the water pump works to reduce the water pressure, the spring 24 pushes the slide column 23 to move to the end away from the spring 24 under the elastic action, so that the shell 22 drives the outlet pipe 221 to rotate downward, reducing the angle of the outlet pipe 221 inclined upward along the horizontal plane, facilitating irrigation of the near position, compared with the outlet pipe 221 with a fixed angle in the traditional way, the applicability is improved, the angle of the liquid inlet 211 can be adjusted by changing the water pressure, which can be used for irrigation of the far place and the near place, and when the outlet pipe 221 rotates, the end part rotates along the perforated plate 31, so that the outlet pipe 221 is aligned with the water outlet hole 311 with different aperture sizes, when the outlet pipe 221 rotates upward to irrigate the far place, the aperture size of the water outlet hole 311 aligned with the outlet pipe 221 is larger, so that the size of the water droplets sprayed by the outlet pipe 221 increases to adapt to the irrigation of the far place, when the outlet pipe 221 rotates downward to irrigate the near place, the aperture size of the water outlet hole 311 aligned with the outlet pipe 221 is smaller, so that the size of the water droplets sprayed by the outlet pipe 221 decreases to adapt to the irrigation of the near place, compared with the nozzle with a fixed aperture size in the traditional way, the size of the sprayed water droplets can be adjusted, and the applicability is improved.
[0028] As Figure 2 and Figure 3As shown, a spiral groove 231 is provided on the sliding column 23, and a slider 222 is fixedly connected to the side of the housing 22 near the sliding column 23. The slider 222 slides in cooperation with the spiral groove 231.
[0029] It should be noted that the spiral groove 231 is spiral in shape.
[0030] In this embodiment, the slider 222 cooperates with the spiral groove 231, so that after the slider 23 moves along the axis, the slider 222 slides along the spiral groove 231. Since the housing 22 cannot move along the axis with the slider 23, the housing 22 rotates around the axis of the slider 23, so that the slider 23 moves and drives the housing 22 to rotate, so as to adjust the angle position of the liquid outlet pipe 221.
[0031] like Figure 2 and Figure 3 As shown, a sliding groove 212 is provided on the tube body 21, and a sliding strip 232 is fixedly connected to the sliding column 23. The sliding strip 232 and the sliding groove 212 are in sliding cooperation.
[0032] It should be noted that the slider 232 and the groove 212 slide in a sliding fit along the axial direction.
[0033] In this embodiment, the slide bar 232 cooperates with the slide groove 212 to prevent relative rotation between the slide column 23 and the tube body 21, making the sliding process of the slide column 23 along the tube body 21 more stable.
[0034] like Figure 3 As shown, a sealing ring 233 is provided between the tube body 21 and the sliding column 23. The sealing ring 233 is fixedly connected to the sliding column 23, and the outer side of the sealing ring 233 is in contact with the inner wall of the tube body 21.
[0035] In this embodiment, the sealing ring 233 prevents liquid from moving from the side near the liquid inlet 211 to the side near the spring 24, thus preventing water leakage and improving sealing performance.
[0036] like Figure 2 As shown, a limiting ring 213 is fixedly connected inside the tube body 21, and the limiting ring 213 is located on the side of the liquid inlet 211 away from the slide column 23.
[0037] It should be noted that the inner diameter of the limiting ring 213 is smaller than the diameter of the sliding column 23.
[0038] In this embodiment, the limiting ring 213 prevents the slide 23 from continuing to move away from the spring 24, thus preventing the slide 23 from separating from the housing 22.
[0039] like Figures 1 to 3 As shown, the end of the tube body 21 away from the slide 23 is provided with a thread 214.
[0040] In this embodiment, the thread 214 facilitates the connection between the pipe body 21 and the water pipe, improving the ease of installation and disassembly of the pipe body 21 and the water pipe.
[0041] The working principle of this utility model is as follows: When the water pressure increases, the water flow pushes the sliding column 23 to move closer to the spring 24. The sliding column 23 drives the outlet pipe 221 to rotate upward through the housing 22, which increases the angle at which the outlet pipe 221 sprays water upward along the horizontal plane. At this time, the end of the outlet pipe 221 is aligned with the outlet hole 311 with a larger diameter, resulting in larger water droplets that are easier to irrigate at a greater distance. When the water pressure decreases, the spring 24 pushes the sliding column 23 to move away from the spring 24. The sliding column 23 drives the outlet pipe 221 to rotate downward through the housing 22, which decreases the angle at which the outlet pipe 221 sprays water upward along the horizontal plane. At this time, the end of the outlet pipe 221 is aligned with the outlet hole 311 with a smaller diameter, resulting in smaller water droplets that are easier to irrigate at a greater distance, thereby improving its applicability.
[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
