[0032] The present utility model provides a spray pipe 10.

[0033] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the spray pipe 10 has a closed end 120 and a water inlet end 110. The water inlet end 110 is used to connect to a water source. The spray pipe 10 is provided with spray openings 211. The spray openings 211 extend along the length direction of the spray pipe 10 and are arranged in an arc shape in the length direction of the spray pipe 10, so that the water flow in the spray pipe 10 can be sprayed out in an arc shape from the spray openings 211.

[0034] Specifically, the spray pipe 10, as a kind of spraying device, can be applied to the field of air purification, and can also be applied to fields such as agricultural irrigation, fire fighting, cooling systems or landscape beautification.

[0035] One end of the spray pipe 10 is the water inlet end 110, and the water inlet end 110 is connected to a water source, such as a water pump or a water supply pipe, to introduce water flow; the other end of the spray pipe 10 is closed to prevent the water flow from flowing away from this end during the spraying process, so as to ensure that the high-pressure water flow inside the spray pipe 10 can be sprayed out from the spray openings 211.

[0036] The water outlet holes of traditional spraying devices are distributed in a dot shape or a linear shape, and the sprayed water flow can only be sprayed out in a straight line along the radial direction of the water pipe, and the spraying coverage range is small. However, the spray openings 211 of the spray pipe 10 proposed by the present utility model extend along the length direction of the spray pipe 10 and are arranged in an arc shape in the length direction of the spray pipe 10. This arc-shaped spray opening 211 changes the spraying trajectory of the water flow, so that the water flow sprayed out from the spray openings 211 can form an arc spraying mode. The water flow naturally forms an arc coverage when sprayed out. Compared with straight or dot spraying, arc spraying can significantly increase the spraying coverage area. At the same time, due to the distribution of the spray openings 211 along the length direction of the spray pipe 10, the uniformity within the spraying range can also be ensured.

[0037] In addition, this design that the spray openings 211 extend along the length direction of the spray pipe 10 can not only increase the spraying coverage area in the length direction of the spray pipe 10, but also reduce the damage to the overall structural strength of the spray pipe 10. It can be understood that for a section of the pipe body in the length direction of the spray pipe 10, if the spray openings 211 extend along the circumferential direction of the spray pipe 10, in order to achieve the same spraying coverage range, multiple spray openings 211 need to be arranged on this section of the pipe body, thereby reducing the structural strength of the spray pipe 10. Moreover, the length that this kind of spray opening 211 extending along the circumferential direction of the spray pipe 10 can extend is restricted more, and its extending length is smaller, so the spraying coverage range is smaller. However, for the spray pipe 10 proposed by the present utility model, since the spray openings 211 extend along the length direction of the spray pipe 10, the spray pipe 10 is not easily broken; moreover, within this section of the pipe body, there is no need to arrange multiple spray openings 211, thereby being able to reduce the damage to the overall structural strength of the spray pipe 10.

[0038] The technical solution of the present utility model is to set the spray orifice 211 of the spray pipe 10 to extend along the length direction of the spray pipe 10 and be arc-shaped in the length direction of the spray pipe 10, so that the water flow in the spray pipe 10 can be sprayed in an arc shape at the spray orifice 211, thereby improving the spray range of the spray pipe 10 and increasing the covered area of the spray.

[0039] In one embodiment, please refer to Figure 1 and Figure 2 , the spray pipe 10 includes a pipe body 100 and a nozzle 200. The pipe body 100 is provided with an installation port 130, the nozzle 200 is arranged in the installation port 130, and the spray orifice 211 is arranged on the nozzle 200.

[0040] One end of the pipe body 100 is a water inlet end 110 for connecting to a water source, and the other end is a closed end 120. The pipe body 100 is provided with an installation port 130, and the function of the installation port 130 is to provide a fixed position for the nozzle 200. The water flow inside the pipe body 100 can be converted into a spray state and sprayed out through the spray orifice 211 on the nozzle 200. By separately arranging the pipe body 100 and the nozzle 200, the pipe body 100 and the nozzle 200 can be processed separately, thereby improving the flexibility of the installation of the pipe body 100 and the nozzle 200. Different nozzles 200 with different arcs and curvatures can be processed according to actual needs, and then the arc and curvature of the spray orifice 211 can be adjusted. In particular, nozzles 200 with an arc or curvature greater than that of the pipe body 100 can be selected, and the spray coverage range is larger. At the same time, different types of nozzles 200 can also be selected for replacement to adapt to different-sized spray areas or specific spray requirements. Moreover, the independence of the nozzle 200 also facilitates maintenance and replacement, reducing the maintenance cost. In addition, since the spray orifice 211 is arranged in an arc shape, its processing difficulty is greater. Processing the spray orifice 211 on a smaller-sized nozzle 200 reduces the processing difficulty. Even if there is an error in processing, it will not affect the structure of the pipe body 100, thereby reducing the risk of processing errors of the spray pipe 10.

[0041] In other embodiments, the spray orifice 211 can also be directly arranged on the pipe body 100, thereby reducing the assembly between components.

[0042] In one embodiment, please refer to Figure 5 , the opposite two inner sidewalls of the spray orifice 211 in the length direction of the pipe body 100 are arranged in a flared shape in the direction away from its axis along the radial direction of the pipe body 100.

[0043] The design of the flared spray port 211 can improve the spray effect of the water flow and form a more diffuse spray pattern. When the water flow is ejected from the spray port 211, the flared design can help the water flow to expand rapidly and form a wider coverage area. The flared design of the spray port 211 can also increase the spray distance of the water flow to a certain extent, because the flared port can help the water flow to obtain better momentum when leaving the spray port 211, so that it can fly a longer distance in the air. Compared with the straight-cylinder spray port 211, the flared design can also reduce the risk of blockage. When the water contains tiny impurities, the flared port can provide a larger passage space, reduce the possibility of impurities blocking the spray port 211, thereby ensuring that the spray pipe 10 can work normally.

[0044] In one embodiment, see Figure 5 The angle formed by the two opposite inner side walls of the spray port 211 in the length direction of the pipe body 100 is θ, 30°≤θ≤150°.

[0045] The angle formed by the spray port 211 relative to the two inner side walls in the length direction of the tube body 100 is θ. When θ is less than 30°, the opening of the spray port 211 will be relatively narrow, which may cause the sprayed water flow to be more concentrated. Although it has a longer spray distance, the spray coverage area is smaller. At the same time, a small-angle expansion design may be more likely to cause blockage. When θ is greater than 150°, the opening of the spray port 211 is wider and the spraying is more uniform, but it may cause the water flow to disperse, resulting in a reduction in the spray force and distance. At the same time, a large-angle design may cause the expansion design to fail. The size of θ can be selected based on the specific needs of the spray, from the coverage range, spray distance and uniformity of the spray.

[0046] In one embodiment, see Figure 2 , Figure 3 and Figure 6 The nozzle 200 includes a spray portion 210 and two connecting portions 220 . The two connecting portions 220 are disposed on opposite sides of the spray portion 210 . The connecting portions 220 are connected to the inner wall of the mounting opening 130 . The spray port 211 is opened in the spray portion 210 .

[0047] The two connecting parts 220 are respectively located on opposite sides of the spray part 210. The connecting parts 220 are connected to the inner wall of the mounting port 130, and are used to fix the nozzle 200 to the pipe body 100 and maintain good sealing to prevent water from leaking from the gap between the nozzle 200 and the mounting port 130, thereby affecting the spraying effect of the spray port 211.

[0048] In other embodiments, the two connecting portions 220 are circumferentially distributed along the circumferential direction of the spraying portion 210. The connecting portions 220 are evenly distributed on the circumference of the spraying portion 210, rather than concentrated on both sides. This can ensure that the nozzle 200 is more firmly installed on the installation opening 130, and at the same time, it can better disperse the pressure from the fluid, improving the stability and reliability of the entire spraying pipe 10. Of course, the number of the connecting portions 220 can also be increased to make them more evenly distributed along the circumferential direction of the entire spraying portion 210.

[0049] In one embodiment, refer to Figure 2 and Figure 4 , the two connecting portions 220 are circumferentially distributed along the circumferential direction of the pipe body 100.

[0050] The two connecting portions 220 are circumferentially distributed along the circumferential direction of the pipe body 100, which can reduce the occupied size of the nozzle 200 in the length direction of the pipe body 100, so that more nozzles 200 can be arranged in the length direction of the pipe body 100. In addition, the stability of the installation of the nozzle 200 can be enhanced, ensuring the uniform force of the nozzle 200 in the circumferential direction of the pipe body 100, thereby improving the firmness of the installation and the overall balance of the spraying pipe 10. Under the working conditions of high pressure or high flow rate of the spraying pipe 10, the connecting portions 220 circumferentially distributed along the pipe body 100 can also help to disperse the impact force generated by the water flow on the nozzle 200, reducing the risk of damage caused by excessive single-point force.

[0051] In other embodiments, the two connecting portions 220 can also be distributed along the length direction of the pipe body 100.

[0052] In one embodiment, refer to Figure 4 and Figure 6 , the connecting portion 220 includes an intersecting first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is connected to the spraying portion 210, and the second connecting portion 222 is connected to the inner wall of the installation opening 130.

[0053] The first connecting portion 221 and the second connecting portion 222 intersect, so that the two together form a complete connecting structure, which helps to improve the strength and stability of the connecting portion 220 itself. At the same time, one side surface of the first connecting portion 221 is in abutting fit with one side of the spraying portion 210, realizing the connection between the spraying portion 210 and the connecting portion 220; the second connecting portion 222 is in abutting fit with the inner wall of the installation opening 130, realizing the connection between the nozzle 200 and the installation opening 130, ensuring that the nozzle 200 can be firmly installed on the installation opening 130.

[0054] The first connecting portion 221 can be connected to the spraying portion 210 by detachable connection means such as bolt fastening, snap and slot cooperation, etc., to achieve the quick installation and disassembly of the spraying portion 210 and the connecting portion 220; it can also be fixedly connected by means such as strong glue bonding, welding, etc., to ensure the stability and sealing performance of the connection between the connecting portion 220 and the spraying portion 210. The second connecting portion 222 can also be connected to the inner wall of the installation opening 130 by means such as bolt fastening, snap and slot cooperation, strong glue bonding, welding, etc., which will not be elaborated here.

[0055] In one embodiment, please refer to Figure 4 and Figure 6 , the connection between the first connecting portion 221 and the second connecting portion 222 is a fillet transition.

[0056] The fillet can effectively disperse stress concentration and prevent cracks or fractures from occurring at the connection between the first connecting portion 221 and the second connecting portion 222. When the connecting portion 220 is subjected to external forces, sharp corners are prone to form stress concentration points, while the fillet can evenly distribute these forces, increasing the strength and durability of the connecting portion 220. The fillet transition not only improves the aesthetics of the connecting portion 220, but also helps to disperse stress, reduce wear, increase safety, and facilitate manufacturing and assembly.

[0057] In one embodiment, the first connecting portion 221 is welded to the spraying portion 210. The first connecting portion 221 and the spraying portion 210 are fixedly connected by welding, which can improve the strength and stability of the nozzle 200. In other embodiments, the connecting portion 220 and the spraying portion 210 may also be integrally formed.

[0058] In one embodiment, the second connecting portion 222 is welded to the inner wall of the installation opening 130. The second connecting portion 222 and the inner wall of the installation opening 130 are fixedly connected by welding, which can improve the firmness and sealing performance of the connection between the second connecting portion 222 and the inner wall of the installation opening 130. At the same time, the gap between the nozzle 200 and the installation opening 130 will be filled during the welding process to ensure the firmness and sealing performance of the connection between the nozzle 200 and the edge of the installation opening 130, preventing water leakage from the installation opening 130, and thus ensuring the spraying effect of the spraying port 211. Welding can be achieved in various ways, which can be arc welding, laser welding, resistance welding, ultrasonic welding, etc.

[0059] In one embodiment, please refer to Figure 6 , the spraying portion 210 is configured as an arc-shaped plate.

[0060] By configuring the spraying portion 210 as an arc-shaped plate, the spraying port 211 can be directly opened on the arc-shaped plate, and the spraying port 211 can form an arc-shaped spraying port 211 along with the shape of the arc-shaped plate, so that the processing of the spraying port 211 is more convenient and fast.

[0061] In one embodiment, referring to Figure 3 , the spray pipe 10 further includes a plug 300 provided at the closed end 120. The plug 300 is detachably connected to the pipe body 100 to block or open the closed end 120.

[0062] During the spraying process of the spray pipe 10, the plug 300 is connected to the closed end 120 of the pipe body 100 to prevent water flow from flowing away from the closed end 120, so as to ensure that the high-pressure water flow inside the spray pipe 10 can be ejected from the spray orifice 211. The detachable design of the plug 300 facilitates the regular cleaning of the sediment inside the spray pipe 10; or during installation or maintenance, opening the plug 300 can check the water flow condition to ensure the normal operation of the system; or before shutdown or medium replacement, opening the plug 300 can discharge the residual liquid in the spray pipe 10 to avoid pollution or corrosion. The plug 300 can be connected to the pipe body 100 by means of threaded connection, snap connection, flange connection, etc. In order to facilitate the removal of the plug 300, a pull tab can also be provided on the outer surface of the plug 300.

[0063] In one embodiment, referring to Figure 1 and Figure 3 , a plurality of spray orifices 211 are provided at intervals along the length direction of the spray pipe 10.

[0064] The plurality of spray orifices 211 are arranged at intervals along the length direction of the spray pipe 10, so that water flow can be evenly ejected at multiple positions in the length direction of the spray pipe 10, thereby helping to improve the coverage area and uniformity of spraying in the length direction of the spray pipe 10. In addition, when an individual spray orifice 211 fails, the other spray orifices 211 can still maintain the normal operation of the spraying work of the spray pipe 10, reducing the risk of system shutdown caused by a single fault point.

[0065] In one embodiment, referring to Figure 3 and Figure 4 , a plurality of spray orifices 211 are provided at intervals along the circumferential direction of the spray pipe 10.

[0066] The spray orifices 211 arranged at circumferential intervals can cover more space around the spray pipe 10, reducing the dead angles or blind areas where the water flow cannot be sprayed, and helping to improve the coverage area and uniformity of spraying in the circumferential direction of the spray pipe 10. The design of the plurality of spray orifices 211 helps to balance the pressure in the circumferential direction of the spray pipe 10, reducing the pressure fluctuation caused by excessive flow rate of the spray orifices 211 on one side, thereby improving the stability and reliability of the entire spray pipe 10. In one embodiment, two spray orifices 211 are oppositely arranged in the circumferential direction of the spray pipe 10.

[0067] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
