Description

Technical Field

[0001] This utility model relates to a nozzle, specifically a near-end water sprayer suitable for irrigation spray guns. Background Technology

[0002] Due to the current structural limitations of irrigation spray guns, the water flow rate at the near end of the spray gun is much lower than that at the far end, resulting in the spray gun not achieving the desired irrigation effect at the near end.

[0003] Currently, utility model patent publication number CN201721202820.4 discloses a near-end sprinkler and a sprinkler gun, including a main connecting pipe seat, a secondary connecting pipe seat, and a nozzle assembly. The nozzle assembly includes a nozzle body with a blind hole bushing structure. The orifice end of the nozzle body is coaxially and tightly connected to the pipe end of the secondary connecting pipe seat through a sealing ring. The nozzle body is axially positioned relative to the pipe end of the secondary connecting pipe seat and is circumferentially rotatable. A nozzle body rotation angle locking structure is also provided between the nozzle body and the pipe end of the secondary connecting pipe seat. A nozzle orifice communicating with the inner cavity of the blind hole of the nozzle body is provided on the cylindrical outer surface of the nozzle body. This near-end sprinkler can be tightly connected to the pressure gauge mounting seat of the sprinkler gun through the mounting structure at the bottom of the main connecting pipe seat. It can achieve water spraying in the area near the sprinkler gun while allowing easy adjustment of the overall spray uniformity of the sprinkler operation area as needed. It is particularly suitable for fixed sprinkler irrigation systems or horizontal sprinkler irrigation machines.

[0004] As can be seen from the above-disclosed technical content, as existing technology, the utility model with announcement number CN214617301U achieves the adjustment of the spraying precipitation near the spray gun and the adjustment of the overall spraying uniformity of the spraying operation area through the installation structure at the bottom of the main connecting pipe seat and the pressure gauge mounting seat of the sprinkler gun in a sealed installation connection. However, the rotation of the nozzle body of this patent requires first loosening the nozzle body rotation angle locking structure, and then adjusting the nozzle body to rotate. After the rotation is completed, the nozzle body rotation angle locking structure must be tightened again, which is not very convenient to use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a near-end sprinkler suitable for irrigation spray guns, which allows the spraying range of the irrigation spray gun to completely cover the near-end position, effectively improving the coverage of the irrigation spray gun and making it easier to adjust the nozzle orientation.

[0006] To achieve the above objectives, this utility model is applicable to the near-end sprinkler of an irrigation spray gun, including a main sprinkler pipe and a horizontal pipe. The main sprinkler pipe and the horizontal pipe are cast as one piece and are cross-shaped. Rotatable nozzle assemblies are installed opposite each other at both ends of the horizontal pipe. The nozzle body of the rotatable nozzle assembly is fixedly connected to the handle tube part, which is inserted into the end of the horizontal pipe. A nozzle mounting groove and a rubber ring groove are sequentially opened on the surface of the handle tube part. A screw mounting seat is provided on the surface of the horizontal pipe, and a screw is screwed into the screw mounting seat and extends into the nozzle mounting groove.

[0007] In addition, the near-end sprinkler for irrigation spray guns proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the main water sprayer is equipped with a valve.

[0009] As a further improvement of this utility model, the end of the water sprayer main pipe is provided with a threaded port.

[0010] As a further improvement of this utility model, the outer surface of the nozzle body is provided with anti-slip texture.

[0011] As a further improvement of this utility model, two or three rubber ring grooves are provided on the handle tube.

[0012] By employing the above-described solution, this utility model possesses at least the following advantages: By installing a near-end sprinkler on the irrigation gun, the spraying range of the irrigation gun can completely cover the nearby area, effectively improving the coverage rate of the irrigation gun. A valve is installed on the main sprinkler pipe, allowing simultaneous control of the on / off state of two rotatable nozzle assemblies. Furthermore, the nozzle body and handle of the rotatable nozzle assembly can be rotated 360 degrees for adjustment without requiring the operation of other accessories. Additionally, the nozzle body is knurled for easier adjustment. The waist-shaped nozzle has a flat waist-shaped opening, resulting in an upper and lower fan-shaped water outlet, better balancing spraying at both near and far distances.

[0022] The following description, in conjunction with the accompanying drawings, describes the near-end water sprayer of this utility model, which is suitable for irrigation spray guns.

[0023] In Embodiment 1 of this application, as Figures 1 to 6 As shown, this near-end sprinkler for irrigation spray guns (hereinafter referred to as "the present invention") includes a main sprinkler pipe 1 and a horizontal pipe 2. The main sprinkler pipe 1 and the horizontal pipe 2 are cast as one piece and are cross-shaped. Rotatable nozzle assemblies 3 are installed opposite each other at both ends of the horizontal pipe 2. The nozzle body 31 of the rotatable nozzle assembly 3 is fixedly connected to a handle tube portion 34, which is inserted into the end of the horizontal pipe 2. A nozzle mounting groove 32 and a rubber ring groove 33 are sequentially formed on the surface of the handle tube portion 34. A screw mounting seat 21 is provided on the surface of the horizontal pipe 2. The screw is screwed into the screw mounting seat 21 and extends into the nozzle mounting groove 32, thus limiting the rotatable nozzle assembly 3. To facilitate the adjustment of the water volume, the main sprinkler pipe 1 is equipped with a valve 5.

[0024] The utility model patent CN201721202820.4 discloses a near-end sprinkler and irrigation gun (hereinafter referred to as "the patent"). The patent achieves the adjustment of the spraying precipitation near the spray gun and the adjustment of the overall spraying uniformity of the irrigation operation area through the installation structure at the bottom of the main connecting pipe seat and the pressure gauge mounting seat of the irrigation gun. However, the rotation of the nozzle body of the patent requires first loosening the nozzle body rotation angle locking structure, and then adjusting the nozzle body to rotate. After rotation, the nozzle body rotation angle locking structure must be tightened again, which is not very convenient to use. In contrast, the present invention allows the nozzle body 31 to be rotated 360 degrees without the need to operate other accessories by inserting the handle 34 of the rotatable nozzle assembly 3 into the horizontal tube 2.

[0025] To further optimize the working efficiency of this application and to facilitate connection to the pre-installed connecting pipe on the irrigation gun, a threaded port 6 is provided at the end of the main water jet 1. Figure 8 As shown, the near-end sprinkler connection pipe 7 on the irrigation nozzle is located above the root of the main nozzle, and the threaded port 6 of the near-end sprinkler is screwed onto the near-end sprinkler connection pipe 7. For easier adjustment, the outer surface of the nozzle body 31 is provided with anti-slip textures or knurling. To further prevent leakage, the handle portion 34 is provided with two or three rubber ring grooves 33.

[0026] When using, install the near-end sprinkler suitable for irrigation spray guns, such as Figure 7 and Figure 8 As shown, the near-end water sprayers can then be put into use.

[0027] When this utility model is used, its specific operation is as follows:

[0028] When using, such as Figure 7 and Figure 8 As shown, first adjust the opening of valve 5 as needed to control the water output. Then, rotate the nozzle body 31 as needed. When the nozzle body 31 rotates, it will drive the handle tube 34 to rotate within the horizontal tube 2. Since the nozzle mounting groove 32 is wrapped around the handle tube 34, the screws screwed into the screw mounting seat 21 can move back and forth in the nozzle mounting groove 32, preventing the rotatable nozzle assembly 3 from coming out, while not restricting the rotation of the rotatable nozzle assembly 3. When the handle tube 34 rotates, the rubber ring in the rubber ring groove 33 can effectively seal the gap between the handle tube 34 and the horizontal tube 2, preventing water from overflowing while allowing the handle tube 34 to be adjusted at any angle under the control of the nozzle body 31. Open the water supply valve of the irrigation spray gun, and the water supply pipe of the main nozzle can simultaneously supply water to the near-end sprayer through the near-end sprayer connecting pipe 7. Finally, the water flow can be sprayed out from the waist-shaped nozzle 4, so that the water outlet shape is an upper and lower fan shape, which better takes into account both long and short distance spraying.

[0029] In summary, the near-end sprinkler of this utility model embodiment, applicable to irrigation spray guns, allows the spraying range of the irrigation spray gun to completely cover the near-field location, effectively improving the coverage rate of the irrigation spray gun. A valve 5 is installed on the main sprinkler pipe 1, which can simultaneously control the on / off state of the two rotatable nozzle assemblies 3. The nozzle body 31 and handle 34 of the rotatable nozzle assembly 3 can be rotated 360 degrees for adjustment without the need for other accessories. The nozzle body 31 is knurled for easier adjustment. The waist-shaped nozzle 4 has a flat waist-shaped opening, resulting in an upper and lower fan-shaped water outlet, better balancing spraying at both near and far distances.
