All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0027] Reference Manual Attached Figure 1-3A four-function pull-out head switching structure includes a water outlet 12, a water divider 11, a fixed ceramic piece 10, a moving ceramic piece 8, a water splash regulator 7, a gear 4, a spring 3, a torsion spring 2, an external water channel 1 and a switching knob 5. The water outlet 12 is provided with four kinds of water splash outlet holes (corresponding to a soft water outlet hole 13, a shower water outlet hole 14, a blade water outlet hole 15 and a natural water outlet hole 16) from the middle to the outside. The water divider 11 is sleeved on the lower part of the water outlet 12 and is provided with a water outlet channel corresponding to the water outlet hole. The water inlet of the water divider is sleeved with the fixed ceramic piece 10. The fixed ceramic piece 10 and the moving ceramic piece 8 form a water diversion structure. The fixed ceramic piece 10 is fixed to the moving ceramic piece 8 by a connecting rod 9 to form the water diversion structure. The moving ceramic piece 8 can rotate around the connecting rod 9. The water distribution structure distributes water through the holes on the movable ceramic plate 8 corresponding to the holes on the fixed ceramic plate 10. The movable ceramic plate is clamped on the water splash regulator 7. Specifically, the outer edge of the three-hole ceramic plate is provided with multiple protrusions, and the water splash regulator is provided with a groove structure that is clamped with the protrusions. The middle part of the water splash regulator is provided with a water passage that matches the external waterway, and the water passage is connected to the external waterway. The lower part of the water splash regulator 7 is sleeved with the gear 4, and the water splash regulator 7 is provided with a rotating ratchet 71 at the corresponding position of the gear 4. The gear inner ring is clamped with the rotating ratchet 71 to realize that the gear drives the rotating ratchet 71 to rotate and then drives the water splash regulator 7 to rotate. The switching knob 5 has a toothed structure, and the outer ring of the gear cooperates with the toothed structure of the switching knob 5 to drive the gear 4 through the switching knob and then drive the moving porcelain piece 8 to rotate in the same direction. The gear outer sleeve is provided with a spring 3 and a torsion spring 4. An anti-reversal device is arranged between the splash regulator 7 and the gear 4. By turning the switching knob to drive the gear to rotate, the holes on the moving porcelain piece 8 are matched with different holes on the fixed porcelain piece 10, thereby realizing the switching of four different splashes through different water outlet holes in the water outlet head through the water distributor.

[0028] It is worth noting that the holes on the fixed ceramic sheet 10 (a total of 12 holes) and the fixed ceramic sheet 8 (corresponding to 3 holes) are shown in the appendix of the specification. Figure 1 The holes are symmetrically distributed around the center, and the holes separated by 3 lead to the water outlet holes with the same water outlet mode (corresponding to the four switching of the fixed tile). Figure 4-5When the switch knob is turned, the torsion spring 2 sleeved on the gear can drive the gear and the switch knob to reset, but the anti-reversal device can prevent the water splash regulator from resetting with the gear. The anti-reversal device is specifically configured as an anti-reversal pawl 72 arranged above the rotating ratchet 71. The anti-reversal pawl cooperates with the end of the torsion spring 2 to realize that the water splash regulator can only rotate in one direction (that is, it can only rotate in the opposite direction of the end of the torsion spring 2). Therefore, when resetting, the gear 4 will rotate back, but the water splash regulator 7 will not rotate with it. Therefore, the final effect of turning the switch knob to reset is that the moving ceramic piece 8 rotates 30o, and the hole corresponding to the fixed ceramic piece becomes the original adjacent hole. Therefore, the water splash mode corresponding to the water outlet hole is also different from the original one, so that the water splash mode can be switched once by turning the switch knob once. Since the holes separated by 3 each other lead to the water outlet with one water outlet mode, turning the switch knob four times can return to the original water outlet mode and realize the switching of four different water splashes.

[0029] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
