When the adjusting plate 3 moves towards the water outlet cover 2, each adjusting pin 31 is inserted into the corresponding water outlet hole 21 and is automatically centered with the water outlet hole 21, thereby forming uniform water outlet gaps.

[0024] It should be noted that in the present embodiment, the movable adjusting pins 31 are arranged on the adjusting plate 3, so that the adjusting pins 31 can be automatically centered when inserted into the water outlet holes 21, thereby avoiding the problem of poor concentricity between the adjusting pins 31 and the water outlet holes 21 caused by manufacturing and assembly errors, so that the water outlet gaps of each water outlet hole 21 are uniform, thereby forming uniform and consistent water spray and improving the water outlet effect.

[0025] In a preferred embodiment, the adjusting plate 3 is provided with mounting holes 32, the adjusting needle 31 is hung on the mounting holes 32 and is at least partially inserted into the mounting holes 32. The adjusting needle 31 is movably hung so as to be adjusted, the mounting holes 32 can limit the adjusting needle 31 so that the adjusting needle 31 can be inserted into the water outlet hole 21.

[0026] Further, the adjusting plate 3 is provided with a plurality of guide grooves 33, the water outlet cover 2 is provided with a plurality of first guide columns 22, and the body 1 is provided with a plurality of second guide columns 13, each first guide column 22 and second guide column 13 are in butt joint and are sleeved in the guide groove 33. The plurality of guide columns and guide grooves 33 are arranged to ensure the smooth movement of the adjusting plate 3 and prevent the adjusting needle 31 from swinging. In an embodiment, each guide groove 33 is arranged to be distributed in a plurality of circumferential directions from the center of the adjusting plate 3, which can reduce the weight of the adjusting plate 3, ensure the movement of the adjusting plate 3, and facilitate the structure arrangement for driving the adjusting plate 3 to move, and can avoid the deflection of the adjusting plate 3 during the movement, so that the movement of the adjusting plate 3 is more stable, and the stability of the water outlet is further ensured. The water outlet cover 2 and the body 1 can be fixed by welding, but are not limited thereto.

[0027] In another embodiment, the water flow can enter the water outlet hole 21 along the periphery of the adjusting plate 3 and each mounting hole 32 and guide groove 33, which can avoid the impact of unidirectional water flow on the adjusting needle 31. At the same time, when the body 1 is a top spray, the number of water outlet holes 21 is large, and the multi-directional water inlet can ensure uniform water inlet.

[0028] On the basis of the above-mentioned embodiments, in an optional embodiment of the utility model, the adjusting needle 31 is sequentially provided with a hanging part 311, an extension part 312, a limiting part 313, a guiding part 314 and a needle part 315 from top to bottom, wherein the hanging part 311 is clamped on the top surface of the mounting hole 32, the extension part 312 is inserted into the mounting hole 32 and is in clearance fit with the mounting hole 32, the limiting part 313 is located on the bottom surface of the mounting hole 32 and is used to limit the distance of the axial movement of the adjusting needle 31, the guiding part 314 is used to cooperate with the inner wall of the water outlet hole 21 to automatically center with the water outlet hole 21, and the needle part 315 is in an elongated shape and is arranged at the bottom of the adjusting needle 31. It needs to be mentioned that the hanging part 311 and the limiting part 313 are arranged to enable the adjusting needle 31 to have a certain distance of axial movement, and at the same time, the adjusting needle 31 can be prevented from being pulled out of the mounting hole 32 after installation. The hanging part 311 can be arranged as a buckle and is inserted into the mounting hole 32 from bottom to top and is clamped with the top surface of the mounting hole 32. The extension part 312 is in clearance fit with the mounting hole 32 to enable the adjusting needle 31 to have a certain ability of circumferential adjustment, so that when the guiding part 314 abuts against the inner wall of the water outlet hole 21, the needle part 315 can be automatically centered with the water outlet hole 21. Preferably, the adjusting needle 31 is integrally injection molded, which can reduce parts and assembly to save cost.

[0029] In another embodiment, the water outlet hole 21 has a guiding section 211 and a water outlet section 212, the guiding section 211 is a taper shape with gradually reduced cross section along the water outlet direction, and the water outlet section 212 is a straight hole vertically extending from the end of the guiding section 211. The needle part 315 is inserted into the straight hole, and the gap between the hole wall of the straight hole and the outer wall of the needle part 315 constitutes a water outlet gap. The guiding section 211 is arranged as a taper shape, and the guiding part 314 is arranged as a plurality of convex ribs arranged along the circumferential direction of the adjusting needle 31, the outer wall surface of each convex rib is similar to the wall surface of the guiding section 211, so that when the outer wall surface of the convex rib abuts against the guiding section 211, the convex rib can be automatically guided, and the needle part 315 is centered with the water outlet hole 21. The water flow enters the water outlet gap along the water inlet groove formed between two adjacent convex ribs. Exemplarily, the diameter of the water outlet section 212 is 1.2 mm, and the diameter of the needle part 315 is 0.8 mm, so that the water flow can be sprayed from the gap of 0.2 mm on one side to increase the water outlet pressure. The diameter of the water outlet section 212 is relatively large, which can be injection molded to reduce cost and assembly, and the needle part 315 is inserted into the water outlet section 212 to prevent the water outlet section 212 from being blocked, which is beneficial to the use of users.

[0030] In other embodiments, the adjusting plate 3 is provided with elastic members 4 between the adjusting plate 3 and the water outlet surface cover 2. When boiling water, the adjusting plate 3 compresses the elastic members 4 to move towards the water outlet surface cover 2 under the water flow pressure. After turning off the water, the adjusting plate 3 moves away from the water outlet surface cover 2 to reset under the elastic force of the elastic members 4. The elastic members 4 are preferably springs. Further, the adjusting plate 3 is provided with elastic members 4 around the shaft center of the adjusting plate 3, so that the adjusting plate 3 can be balanced in the moving process. In addition, the adjusting plate 3 drives the adjusting needle 31 to move in and out of the water outlet hole 21 in the moving process, which can play a descaling effect. Moreover, the water outlet cross section of the water outlet hole 21 is enlarged after turning off the water, so that air can enter the water outlet cavity and accelerate the discharge of residual water in the water outlet cavity.
