For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] refer to Figures 1-6 This embodiment provides a water path switching device 2, which is mounted on a pull-out shower head and is used to switch between different water paths of at least two sets of water outlet components inside the pull-out shower head.

[0036] like Figure 1 The shower body 1 of the pull-out shower head includes a water inlet end 5, a first water outlet component 3, and a second water outlet component 4. The first water outlet component 3 and the second water outlet component 4 are independent of each other and are arranged axially within the shower body 1. The water path switching device 2 is arranged axially within the shower body 1. The water path switching device 2 includes a press-to-switch mechanism 21 and a switching shaft 22 connected to the press-to-switch mechanism 21. In this embodiment, the press-to-switch mechanism 21 adopts a structure of hook 6 and guide groove 7 to achieve pressing. As the pressing end 211 of the press-to-switch mechanism 21 is pressed, the switching shaft 22 can automatically extend and retract during the pressing and releasing actions.

[0037] When the switching mechanism 21 is pressed, the switching shaft 22 can automatically extend and retract along the axial direction, and has a first position and a second position in the direction of movement. In the first position, the switching shaft 22 switches to correspond with the first water outlet component 3, connecting the water passage of the first water outlet component 3. At this time, water is discharged from the first water outlet component 3, and water is not discharged from the second water outlet component 4. In the second position, the switching shaft 22 switches to correspond with the second water outlet component 4, connecting the water passage of the second water outlet component 4. At this time, water is discharged from the second water outlet component 4, and water is not discharged from the first water outlet component 3.

[0038] In this embodiment, the pressing end 211 of the pressing switching mechanism 21 is assembled with the second water outlet component 4, and the second water outlet component 4 is configured to be pressable inward and outward along the cavity wall 11 of the shower body 1. The second water outlet component 4 serves as the button of the pressing switching mechanism 21. The pressing switching mechanism 21 is located at the front end along the water flow direction along the switching shaft 22, and the pressing end 211 is located at the front end of the pressing switching mechanism 21 along the water flow direction.

[0039] The second water outlet component 4 includes a water outlet 41. In conjunction with the pressing mechanism of the second water outlet component 4, the second water outlet component 4 is configured to extend or retract along the cavity wall 11 of the shower head body 1. When the second water outlet component 4 extends, water can flow from the water outlet 41. The pressing function is achieved by combining the hook 6 and guide groove 7 of the pressing switching mechanism 21 in this embodiment. To enable the second water outlet component 4 and the switching shaft 22 to be controlled to extend and retract through the same pressing action, a spring-loaded component is provided between the pressing switching mechanism 2 and the mouthwash water outlet structure 1. A hook block 8 is provided in the guide groove 7. In conjunction with the groove wall, the hook 6 moves downwards along the inclined side of the hook block 8 during the pressing process. Combined with the side inclined side of the guide groove, the spring-loaded component allows the hook 6 to either hook onto the hook block 8 (first position) or the groove wall (second position), ensuring that the second water outlet component 4 and the switching shaft 22 extend and retract synchronously. The linkage mechanism includes a hook 6 and a guide groove 7. The movement of the hook 6 within the guide groove 7 allows the second water outlet component 4 to switch between retracted and extended states when pressed. Figure 5 .

[0040] The synchronous extension and retraction of the second water outlet component 4 and the switching shaft 22 can reduce the change in the total length of the pull-out shower head. Furthermore, by hiding the button of the pressing switching mechanism 21 on the second water outlet component 4, the active structure specifically designed for the button can be reduced, thus simplifying the overall structure of the pull-out shower head and ensuring good consistency and aesthetic appeal.

[0041] like Figure 4In this embodiment, the different water path switching structure of the switching shaft 22 is configured such that a first water outlet chamber 23 and a second water outlet chamber 24 are provided on the switching shaft 22 along the axial direction, and the first water outlet chamber 23 and the second water outlet chamber 24 are not connected to each other. The first water outlet chamber 23 provides water outlet for the first water outlet component 3, and the second water outlet chamber 24 provides water outlet for the second water outlet component 4.

[0042] The first water outlet assembly 3 has a side outlet 25 on its side wall, and the second water outlet chamber 24 has a side inlet 26 on its side wall. A side water flow channel 29 is provided between the side outlet 25 and the side inlet 26. The switching mechanism 21 can control the flow or blockage of the side water flow channel 29, controlling the first water outlet chamber 23 to supply water to the first water outlet assembly 3 or to the second water outlet chamber 24 through the side water flow channel 29. The second water outlet chamber 24 is directly connected to the second water outlet assembly 4, and water can directly exit from the second water outlet assembly 4 after entering the second water outlet chamber 24.

[0043] A first blocking section 27 is provided at the junction of the first water outlet chamber 23 and the second water outlet chamber 24. As the switching shaft 22 moves axially, the first blocking section 27 opens or closes the water flow channel 29. To ensure that the water flow is unidirectional when the first water outlet chamber 23 discharges water into the second water outlet chamber 24, a second blocking section 28 is provided at the rear end of the first water outlet chamber 23 opposite to the water flow direction. When the first water outlet chamber 23 discharges water into the second water outlet chamber 24, the second blocking section 28 closes the inlet 31 of the first water outlet device.

[0044] To ensure water tightness, sealing rings 20 are fitted on both the first blocking section 27 and the second blocking section 28. Hollow water channels are provided inside the switching shaft 22 to fit the first water outlet chamber 23 and the second water outlet chamber 24. The first blocking section 27 and the second blocking section 28 are located on the outer wall of the switching shaft 22. The blocking function is achieved by the outer wall of the switching shaft 22 and the sealing rings 20 working together with the shower body 1 and the cavity wall of the switching shaft 22, which are adapted to each other in diameter, to form an airtight fit.

[0045] In this embodiment, the water path switching operation for the first water outlet component 3 and the second water outlet component 4 is as follows:

[0046] like Figure 2When the first water outlet component 3 is pressed, the second water outlet component 4 is pressed. With the cooperation of the hook 6 and the guide groove 7, the hook 6 moves inward and hooks onto the hook block 8. The second water outlet component 4 retracts inward into the cavity wall 11 of the shower body 1 and maintains the retracted state. When the second water outlet component 4 is pressed, the switching shaft 22 moves backward in the opposite direction of water flow. At this time, the switching shaft 22 is located at the first position. The side outlet 25 of the first water outlet cavity 23 corresponds to the inlet 31 of the first water outlet component 3. The first blocking section 27 moves backward in the opposite direction of water flow and is misaligned with the side water flow channel 29. Under the action of the sealing ring 20, it forms a seal with the cavity wall 11 of the shower body 1 at this position, thereby closing the flow of the side water flow channel 29. The water flows in from the inlet end 5, flows to the first water outlet cavity 23 of the switching shaft 22, and flows into the inlet 31 of the first water outlet component 3 from the side outlet 25, realizing the water supply of the first water outlet component 3.

[0047] like Figure 3 When the second water outlet component 4 is pressed, with the cooperation of the hook 6 and the guide groove 7, the hook 6 extends outward and hooks onto the groove wall of the guide groove 7. The second water outlet component 4 extends outward from the cavity wall 11 of the shower body 1 and remains extended. The water outlet 41 of the second water outlet component 4 is in a water-discharging state. When the second water outlet component 4 is pressed, the switching shaft 22 moves forward synchronously along the water flow direction. At this time, the switching shaft 22 is in the second position. The side water outlet 25 of the first water outlet cavity 23 is misaligned with the water inlet 31 of the first water outlet component 3. The inlet 31 of component 3 is blocked by the second blocking section 28; the first blocking section 27 moves forward along the water flow direction to be opposite to the side water flow channel 29, thereby opening the flow of the side water flow channel 29. The water flows in from the inlet end 5, flows to the first outlet chamber 23 of the switching shaft 22, and flows into the side water flow channel 29 through the side outlet 25. It then flows through the side water flow channel 29 to the side inlet 26 of the second outlet chamber 24, thus supplying water to the second outlet chamber 24. The water flows from the second outlet chamber 24 to the second outlet assembly 4, and is discharged from the outlet 41 of the second outlet assembly 4.

[0048] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
