Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, a novel spray gun includes a first tube 1 and a second tube 2. The first tube 1 is horizontally mounted on the upper part of the second tube 2 and is connected to the second tube 2. A connection port is fixedly connected to the lower end of the second tube 2. A reversing valve 3 is provided inside the first tube 1. A water nozzle assembly is provided on one side of the first tube 1, and a rotating handle 23 is rotatably provided on the other side. The reversing valve 3 includes a valve body and a valve core. The valve body includes an inlet and at least two outlets. The valve core is rotatably mounted in the valve body. A valve cover 4 is connected between the end of the valve body near the rotating handle 23 and the inner wall of the first tube 1. The rotating handle 23 is connected to the valve core, and the rotating handle 23 drives the valve core to rotate, thereby causing one of the outlets to connect with the first tube 1. The inlet is connected, and a water outlet connector 7 is provided between the reversing valve 3 and the water nozzle assembly. The water outlet connector 7 has multiple water inlets corresponding to each water outlet. The water nozzle assembly includes a water spray replacement plate 5 and a direct spray connector 6. The direct spray connector 6 is installed in the middle of the water outlet connector 7. The water spray replacement plate 5 is slidably sleeved on the surface of the direct spray connector 6, and both the water spray replacement plate 5 and the direct spray connector 6 are embedded inside the first pipe body 1. Each water inlet is connected to the water spray replacement plate 5 and the direct spray connector 6 respectively. By rotating the rotating handle 23, the valve core is driven to rotate, thereby switching the connection between the inlet and different water outlets so that water flows into the direct spray connector 6 or the water spray replacement plate 5, thereby switching between the two modes of powerful cleaning and gentle care.

[0023] In this embodiment, the water spray replacement plate 5 includes an annular seat 8. The outer annular surface of the annular seat 8 has a first groove 9, and the inner annular surface of the annular seat 8 has a second groove 10. Both the first groove 9 and the second groove 10 are fitted with sealing rings 11. The end face of the annular seat 8 has a plurality of water spray outlet holes 12. The end of the first tube body 1 near the water nozzle assembly is threadedly connected to a limiting member 13. The middle part of the limiting member 13 has a through-hole 19 that matches the annular seat 8, and a filter screen 14 is provided on the through-hole 19.

[0024] The water spray replacement piece 5 is designed to be detachable. When the user needs water spray outlets 12 with different structures (different hole diameters, arrangements, or texture designs) to achieve a specific water flow pattern (such as columnar, spray, or pulse), simply unscrew the limiting member 13 to remove the annular seat 8. Then, insert another annular seat 8 with different water spray outlets 12 into the first tube body 1. Finally, screw the limiting member 13 back in and abut it against the annular seat 8 to ensure that the annular seat 8 will not move due to water flow impact. The sealing rings 11 in the first groove 9 and the second groove 10 can ensure that there will be no water leakage at the contact points between the annular seat 8 and the inner wall of the first tube body 1 and the direct spray connector 6.

[0025] In this embodiment, a receiving groove 15 is provided at one end of the second pipe body 2 near the water nozzle assembly. Several spray holes 16 are provided on the receiving groove 15, and the spray holes 16 communicate with the interior of the second pipe body 2. A partition 17 is provided inside the second pipe body 2, and a diverting valve 18 is provided at the bottom end of the partition 17. The partition 17 divides the interior of the second pipe body 2 into two independent spaces, one of which communicates with the first pipe body 1, and the other space communicates with the spray holes 16. A through-hole 19 is provided on one side of the diverting valve 18, and annular fixing seats 20 are installed at both the upper and lower ends of the diverting valve 18. The fixing seats 20 are connected to the inner wall of the second pipe body 2, and a rotating component 2 is rotatably mounted on the second pipe body 2. 4. The inner end of the rotating part 24 passes through the second pipe body 2 and is connected to the side wall of the diverting valve 18, so that the diverting valve 18 can be rotated by rotation. The cover 21 is slidably mounted on the receiving groove 15. The receiving groove 15 has a receiving cavity on the side for the cover 21 to enter. The bottom of the receiving groove 15 has a slide that extends through to the rotating part 24. The bottom of the cover 21 extends through the slide to connect with the inner end of the rotating part 24. The outer wall of the fixed seat 20 has a third groove. The third groove is embedded with a sealing strip 22. The bottom of the space communicating with the water spray hole 16 is provided with a diverting seat 25. The diverting seat 25 is provided with multiple diverting fins 26. The diverting fins 26 are used to uniformly distribute the water flow.

[0026] When the user uses this device for shower assistance or large-area bathroom surface rinsing, simply rotate the rotating component 24 to drive the diverting valve 18 to rotate, causing the inlet 19 to rotate to the space communicating with the spray hole 16. At this time, water flows into the space through the inlet 19 and sprays out from the spray hole 16 to form a large-area water curtain, which is particularly suitable for large-area rinsing of bathroom walls and shower room glass. When the rotating component 24 rotates to another space, allowing water to enter the first pipe body 1, the cover 21 will rotate synchronously with the rotation of the rotating component 24. At this time, the cover 21 covers the receiving groove 15, making it convenient for the user to hold and also preventing stains from adhering to the spray hole 16 when it is not in use.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
