Description

Technical Field

[0001] This utility model relates to the field of water-stop switching valve technology, specifically to a water-stop switching valve and a water outlet device. Background Technology

[0002] See Figure 1-3 As shown, the existing shower head has a stop valve including a valve seat 1', a push-button switch mounted on the valve seat 1', and a valve cover sleeved outside the valve seat 1'. The push-button switch includes a valve core 2', a valve core fixing part 3', and a button cap 4'. The valve core fixing part 3' is provided with an elastic buckle 31', and the valve seat 1' is provided with a limit buckle 11'. By pressing the valve core 2' and the valve core fixing part 3' downward together, the elastic buckle 31' and the limit buckle 11' are engaged and limited, thereby fixing the valve core 2' and the valve core fixing part 3' together onto the valve seat 1'.

[0003] To facilitate the installation and removal of the push-button switch, the valve cover must be designed as a split structure, consisting of an upper valve cover 5' and a lower valve cover 6'. When assembling the water-stop switching valve, the valve core 2' and valve core fixing part 3' of the push-button switch must be installed together on the valve seat 1' before the valve cover can be installed. When disassembling the water-stop switching valve, the valve cover must be removed first to create sufficient operating space before the operator can apply force to pry open the elastic buckle 31' and release the locking buckle 11'. Only then can the valve core 2' and valve core fixing part 3' of the push-button switch be pulled upwards from the valve seat 1'. This assembly and disassembly process is cumbersome and inconvenient. Furthermore, the split structure of the valve cover results in low structural strength of the shower head, making the valve cover prone to cracking. This can lead to the separation and ejection of various components inside the push-button switch, making it less sturdy and durable, and also less aesthetically pleasing. Utility Model Content

[0042] Example 1.

[0043] See Figure 4-15As shown in the figure, as an embodiment of this utility model, a water-stop switching valve is provided for installation on a shower head. It includes a valve seat 1, a push-button switch 2, and an integrated valve cover 3. The valve cover 3 is fitted over the valve seat 1, and the valve seat 1 has a receiving cavity 4. The valve cover 3 has a clearance hole 5. The push-button switch 2 includes a valve core 2.1, a valve core fixing member 2.2, and a button cap 2.3. The valve core 2.1 is elastically extended and retracted within the receiving cavity 4 via an elastic element, specifically a spring 6. The valve core fixing member 2.2 is mounted on the valve core 2.1 to achieve [the desired effect]. The button cap 2.3 is detachably mounted on the top of the valve core 2.1 through the clearance hole 5. The valve core fixing part 2.2 is provided with a lower limit part 2.24, and the valve seat 1 is provided with an upper limit part 7. By pressing and rotating the valve core fixing part 2.2, the upper limit part 7 and the lower limit part 2.24 are engaged in a vertical blocking and limiting cooperation, thereby fixing the valve core fixing part 2.2 on the valve seat 1. The valve core fixing part 2.2 is used to block and limit the valve core 2.1 in the upward direction to prevent the valve core 2.1 from popping upward out of the receiving cavity 4.

[0044] When assembling the water-stop switching valve: First, place the valve cover 3 over the valve seat 1. Then, assemble the valve core 2.1 and the valve core fixing part 2.2 together and insert them into the receiving cavity 4 of the valve seat 1 through the clearance hole 5. An elastic element is provided between the bottom end of the valve core 2.1 and the inner bottom wall of the receiving cavity 4, so that the valve core 2.1 elastically extends and retracts within the receiving cavity 4. By pressing and rotating the valve core fixing part 2.2, the lower limit part 2.24 moves downward past the upper limit part 7 and rotates to the upper limit part 7. At the directly below position, the upper limit part 7 and the lower limit part 2.24 are engaged in an upper and lower blocking and limiting cooperation, thereby fixing the valve core fixing part 2.2 on the valve seat 1. At this time, the valve core fixing part 2.2 blocks and limits the valve core 2.1 in the upward direction to prevent the elastic element from popping the valve core 2.1 out of the receiving cavity 4. The valve core 2.1 and the valve core fixing part 2.2 are assembled. Then, the button cap 2.3 is detachably installed on the top of the valve core 2.1 through the clearance hole 5, thereby completing the assembly process of the water-stop switching valve. When it is necessary to disassemble the push-button switch 2 of the water-stop switching valve: first, pull the button cap 2.3 upwards to push out the top of the valve core 2.1, so that the valve core 2.1 and the valve core fixing part 2.2 are exposed to the clearance hole 5. Then, rotate the valve core fixing part 2.2 with an external tool or by hand, so that the lower limit part 2.24 is rotated to the position directly below the upper limit part 7. The upper limit part 7 and the lower limit part 2.24 are released from the upper and lower blocking limit cooperation, and the valve core 2.1 and the valve core fixing part 2.2 can be removed from the valve seat 1 together. This structure makes the assembly and disassembly of the water-stop switching valve simple and convenient. Moreover, the valve cover 3 is an integral structure, which makes the shower head structurally strong. The valve cover 3 will not crack when dropped, and it can effectively prevent the various parts in the push-button switch 2 from separating and falling out, making it more robust and durable, with a better overall feel and a more harmonious and beautiful appearance.

[0045] In this embodiment, the valve seat 1 includes a valve seat body 1.1 and a water outlet 1.2 and a water inlet 1.3 disposed at the front and rear ends of the valve seat body 1.1. The receiving cavity 4 is disposed on the valve seat body 1.1. The valve seat body 1.1 is provided with a water inlet hole 12 and a water outlet hole 13. The water outlet 1.2 and the receiving cavity 4 are connected through the water outlet hole 13, and the water inlet 1.3 and the receiving cavity 4 are connected through the water inlet hole 12. A sealing element 2.4 is sleeved on the bottom of the valve core 2.1. The sealing element 2.4 is used to movably block the water inlet hole 12, thereby realizing the water stop or water flow switching of the shower head's water stop switching valve.

[0046] In this embodiment, the top of the valve seat body 1.1 is provided with a concave flat surface 14, and a tubular body 15 is provided protruding upward from the flat surface 14. The receiving cavity 4 is located inside the tubular body 15. The upper limit part 7 is respectively provided on the front and rear opposite sides of the outer wall of the tubular body 15. The valve core fixing member 2.2 includes a hollow column 2.21 and L-shaped cantilever arms respectively connected to the opposite sides of the hollow column 2.21. The L-shaped cantilever arm includes a transverse rod 2.22 and a longitudinal rod located at one end of the transverse rod 2.22 and extending downward. The bottom ends of the longitudinal rods 2.23 of the two L-shaped cantilever arms extend horizontally towards the opposite side to form the lower limiting part 2.24. The upper limiting part 7 and the lower limiting part 2.24 cooperate to block and limit each other, thereby fixing the valve core fixing part 2.2 on the valve seat 1, thereby blocking and limiting the valve core 2.1 in the upward direction to prevent the valve core 2.1 from popping out of the receiving cavity 4. This structure makes the space occupied by the valve core fixing part 2.2 smaller, and the assembly and disassembly operations more convenient and quick.

[0047] In this embodiment, the valve core 2.1 is provided with a receiving groove 10, and the upper part of the valve core 2.1 is provided with U-shaped sliding grooves 11 communicating with the receiving groove 10 on opposite sides. The hollow column 2.21 is installed in the receiving groove 10, and two L-shaped cantilevers 2.22 are respectively installed on the U-shaped sliding grooves 11 on both sides, so that the valve core fixing member 2.2 and the valve core 2.1 can rotate synchronously and cooperate, so that when the valve core 2.1 is fixed, the valve core fixing member 2.2 can be anti-rotation limited.

[0048] In this embodiment, buckles 9 are provided on both sides of the top of the valve core 2.1, and slots 2.31 are provided on both sides of the inner top of the button cap 2.3. The buckles 9 and the slots 2.31 engage to allow the button cap 2.3 to be detachably installed on the top of the valve core 2.1.

[0049] In this embodiment, slot holes 16 are respectively provided on the left and right sides of the valve seat 1 corresponding to the tubular body 15. The left and right sides of the button cap 2.3 are respectively provided with downwardly extending insertion parts 2.32. The insertion parts 2.32 are inserted into the slot holes 16 one by one, thereby preventing the button cap 2.3 from rotating horizontally on the valve seat 1, thereby preventing the valve core 2.1 and the valve core fixing part 2.2 from rotating, and ensuring the assembly stability of the button switch 2.

[0050] In this embodiment, the button cap 2.3 and the clearance hole 5 are elliptical shapes that correspond to each other, thereby providing a function of preventing rotation and limiting the button cap 2.3.

[0051] In this embodiment, the valve cover 3 is a three-way tube, which includes a main sleeve 3.1 that runs through the front and back and a protruding tube 3.2 that is set on the top of the main sleeve 3.1 and extends upward. The clearance hole 5 is located inside the protruding tube 3.2. The main sleeve 3.1 enters through the water inlet pipe 8 port 1.3 and is sleeved on the outside of the valve seat body 1.1. Specifically, a limiting groove 17 is provided on the circumferential outer wall of the valve seat body 1.1 near the water inlet pipe 8 port 1.3, and a limiting insert 18 is provided on the circumferential inner wall of one end of the main sleeve 3.1. The limiting insert 18 and the limiting groove 17 are inserted and cooperated to limit the circumferential rotation of the main sleeve 3.1. Furthermore, a first limiting buckle 19 and a first blocking part 20 are provided on the inner wall of the main sleeve 3.1, and a second limiting buckle 21 and a second blocking part 22 are provided on the valve seat body 1.1. The first limiting buckle 19 and the second limiting buckle 21 are locked in a front-to-back locking fit, so that the valve cover 3 will not automatically move backward and exceed the designated assembly position after reaching the designated assembly position. The first blocking part 20 and the second blocking part 22 are locked in a front-to-back blocking fit, so that the valve cover 3 will not continue to move forward and exceed the designated assembly position after reaching the designated assembly position, ensuring the assembly accuracy and stable reliability of the valve cover 3. Among them, the first limiting buckle 19 and the second limiting buckle 21 are two oppositely arranged. The first blocking part 20 is located on the circumferential inner wall of the rear end of the main sleeve 3.1, and the second blocking part 22 is located on the circumferential outer wall of the valve seat body 1.1 near the end of the water inlet pipe 8 port 1.3.

[0052] Among them, a switching shaft assembly for realizing press switching is also installed between the receiving groove 10 of the valve core 2.1 and the hollow column 2.21. This is existing technology and will not be described in detail here.

[0053] This utility model also provides a water outlet device, specifically a shower head, which includes the water-stop switching valve, water inlet pipe 8, and shower head described in the above embodiment. The shower head is installed at the water outlet 1.2 of the water-stop switching valve, and the water inlet pipe 8 is installed at the water inlet 8 port 1.3 of the water-stop switching valve. The water inlet pipe 8 is installed at the water inlet 8 port 1.3 of the water-stop switching valve by means of threaded connection or snap-fit ​​9. The assembly and disassembly process of this shower head is relatively simple and convenient, and the valve cover 3 is an integral structure, which makes the structure of the shower head have high strength. The valve cover 3 will not crack when dropped, and it can effectively prevent the various parts in the button switch 2 from separating and falling out, making it more robust and durable, with a better overall feel and a more harmonious and beautiful appearance.

[0054] Example 2: For the sake of brevity, this example mainly describes the differences from Example 1.

[0055] See Figure 16-19 As shown in the figure, as an embodiment of the present invention, a water-stop switching valve is provided. The longitudinal rods 2.23 of the two L-shaped cantilever arms are respectively provided with grooves 23 on opposite sides. The valve seat 1 is provided with spring buckles 24 on opposite front and rear sides of the top. The spring buckles 24 can generate elastic deformation in the front and rear direction. The spring buckles 24 and the grooves 23 are elastically locked and limited. Specifically, the front and rear spring buckles 24 are respectively located in front of and behind the front and rear upper limit parts 7, so that when the spring buckles 24 and the grooves 23 are elastically locked and limited, the upper limit part 7 and the lower limit part 2.24 are also just locked and limited, realizing double fixed limiting, further improving the assembly stability of the valve core fixing part 2.2 on the valve seat 1, and thus ensuring the assembly stability of the push button switch 2.

[0056] In this embodiment, a blocking block 25 is provided on the top of the valve seat 1. The blocking block 25 is located on the flat cut surface 14 on one side between the spring buckle 24 and the upper limit part 7. The blocking block 25 is used to block and cooperate with the longitudinal rod 2.23 of the L-shaped cantilever to achieve anti-rotation positioning, prevent the valve core fixing part 2.2 from continuing to rotate after being assembled in place, further improve the assembly stability of the valve core fixing part 2.2 on the valve seat 1, and thus ensure the assembly stability of the push button switch 2.
