[0029] In this embodiment, by providing a mounting notch 12 and a positioning hole 13 on the periphery of the spray port 11, the extension block 22 on the spray plate is conveniently extended into the mounting notch 12, and the connecting bolt 23 penetrates the extension block 22 and the mounting notch 12, so that the entire spray mesh plate 21 is installed at the spray port 11, and during the installation process, by extending the positioning column 24 into the positioning hole 13, the spray mesh plate 21 is conveniently and quickly assembled, which greatly improves the installation efficiency of the staff. When the subsequent spray mesh plate 21 is damaged or the mesh surface needs to be disassembled and cleaned, it is also convenient for the staff to quickly disassemble it. While improving the installation efficiency of the staff, it ensures the normal use of the spray pipe 1, and greatly improves the working efficiency of the entire spray device.

[0030] In one embodiment, see Figure 2To facilitate the installation of the extension block 22 in the first notch 121, the installation notch 12 includes three first notches 121 and three first threaded holes 1211 corresponding to the first notches 121. A buffer end 14 is arranged in any first notch 121. An extension block 22 is provided in the first notch 121. A second threaded hole 221 matching the first threaded hole 1211 is opened on the extension block 22. One end of the connecting bolt 23 passes through the second threaded hole 221 and the first threaded hole 1211. The buffer end 14 includes a spring bar 141 and a force plate 142. A spring bar 141 is connected to any first notch 121, and the end of the spring bar 141 is connected to the force plate 142. One end of the extension block 22 abuts against the force plate 142.

[0031] In this embodiment, three first notches 121 are arranged in a triangular shape on the spray pipe 1, and a first threaded hole 1211 is opened in each first notch 121, and a spring bar 141 is connected to the inner wall of the first notch 121, and the end of the spring bar 141 is connected to the force plate 142. When the extension block 22 extends to the first notch 121, the end of the extension block 22 will abut against the force plate 142, and push the force plate 142 to squeeze the spring bar 141, causing the spring bar 141 to deform. When the second threaded hole 221 on the extension block 22 coincides with the first threaded hole 1211, the connecting bolt 23 penetrates the second threaded hole 221 and the first threaded hole 1211, and prompts the extension block 22 to be installed in the first notch 121, thereby prompting the spray mesh plate 21 to be installed at the spray port 11.

[0032] In one embodiment, see Figure 3 In order to further improve the installation efficiency of the spray screen 21, the installation gap 12 also includes three second gaps 122, and a connecting column 1221 is arranged in any second gap 122. The filtering mechanism also includes three plastic blocks 25, and any plastic block 25 is provided with a C-shaped snap-fitting opening 251, which is used to snap on the connecting column 1221.

[0033] In this embodiment, three of the second notches 122 are also arranged in a triangular shape on the periphery of the spray port 11, and the space of the second notch 122 is larger than the first notch 121. A connecting column 1221 is arranged in each second notch 122, and a plastic block 25 with a C-shaped snap-fitting opening 251 is provided on the spray mesh plate 21. The plastic block 25 has a certain deformation effect and can be snapped on the connecting column 1221, thereby further enhancing the connection efficiency between the entire spray mesh plate 21 and the spray port 11.

[0034] In one embodiment, see Figure 2-5In order to change the spray angle of the device, the lower end of the spray pipe 1 is connected to a carrier frame 3, and a water supply box 4 is arranged at the lower end of the carrier frame 3. The carrier frame 3 includes a frame body 31, a rotating shaft 32 and a rotating rod 33; the frame body 31 is a U-shaped frame, and the frame body 31 and the spray pipe 1 are rotatably connected through the rotating shaft 32, and a rotating rod 33 is fixed to the lower end of the frame body 31, and the rotating rod 33 is rotatably connected to the water supply box 4. The water supply box 4 is respectively provided with a water inlet and a drain, and the water inlet and the drain are both connected with a sealing plate. The water supply box 4 is connected to the spray pipe 1 through a water guide pipe 41, and a water pump is installed inside the water supply box 4 and on the water guide pipe 41.

[0035] A rotating rod 33 is provided on the water supply box 4, so that the rotating rod 33 can be used to drive the entire frame 31 to rotate circumferentially. Since the frame 31 is connected with the spray tube 1, when the frame 31 rotates, the spray tube 1 rotates circumferentially synchronously, and the spray tube 1 is rotatably connected to the frame 31 through the rotating shaft 32. Therefore, the spray angle of the spray tube 1 can be adjusted through the rotating shaft 32, thereby improving the adaptability of the device, and the water supply box 4 and the spray tube 1 are connected through the water pipe 41, so that liquid is provided to the inside of the spray tube 1. The water pipe 41 is a retractable tube body. When the spray tube 1 rotates circumferentially or adjusts the angle, the length of the water pipe 41 will change adaptively without breaking.

[0036] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail: when the staff needs to install the spray screen plate 21 at the spray port 11, the fixed position on the spray screen plate 21 is inserted into the positioning hole 13 on the outer periphery of the spray port 11, and the snap-fitting opening 251 on the plastic block 25 is snapped on the connecting column 1221 in the second notch 122. At this time, the extension block 22 enters the first notch 121 and abuts against the force-bearing plate 142. The spring bar 141 is pushed to deform through the force-bearing plate 142. When the spring bar 141 is deformed, the extension block 22 moves inward in the first notch 121. When the second threaded hole 221 on the extension block 22 coincides with the first threaded hole 1211, the connection The bolt 23 threadably connects the extension block 22 into the first notch 121, thereby facilitating the assembly of the spray mesh plate 21 at the spray port 11. When disassembly is required later, the staff only needs to remove the connecting bolt 23, and then bend the plastic block 25 to deform it, so that the engaging opening 251 is expanded and no longer engaged with the connecting column 1221. At this time, the elastic force of the spring bar 141 pushes the force-bearing plate 142 to push the extension block 22 outward, so that the spray mesh plate 21 can be quickly disassembled, which greatly improves the installation and disassembly efficiency of the staff, and facilitates the replacement of the spray mesh plate 21, thereby avoiding untimely replacement of the spray mesh plate 21 after damage, thereby affecting the working efficiency of the entire spray pipe 1.
