Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] A shower head switch valve core, such as Figures 1-7 As shown, it includes a base 1, a housing 2, a fixed ceramic plate 3, a moving ceramic plate 4, a linkage seat 5, a valve stem 6, an inlet channel 7, and an outlet channel 8.

[0029] The base 1 is connected to the housing 2. Specifically, the base 1 is provided with a connecting hook 17, and the side wall of the housing 2 is provided with a connecting hole 18. The connecting hook 17 is engaged with the connecting hole 18. In this embodiment, there are two connecting hooks 17 and they are arranged opposite each other, and there are two connecting holes 18 and they are arranged opposite each other. The connecting hooks 17 and the connecting holes 18 correspond to each other. It should be noted that by engaging the connecting hooks 17 and the connecting holes 18, not only can a stable connection between the base 1 and the housing 2 be achieved, but the assembly of the two is also simpler.

[0030] The base 1 is provided with an assembly protrusion 20, and the side wall of the housing 2 is provided with an assembly groove 21. The assembly protrusion 20 is inserted into the assembly groove 21. In this embodiment, there are two assembly protrusions 20 and they are arranged opposite to each other. There are two assembly grooves 21 and they are arranged opposite to each other. The assembly protrusions 20 and the assembly grooves 21 correspond to each other. The cooperation between the assembly protrusions 20 and the assembly grooves 21 can not only keep the base 1 and the housing 2 relatively stable, but also, during assembly, the relative positional relationship between the assembly protrusions 20 and the assembly grooves 21 can quickly engage the connecting hook 17 with the connecting hole 18, making the assembly more convenient and faster.

[0031] The ceramic tile 3 is circumferentially fixed on the base 1. Specifically, the base 1 is provided with a positioning block 10, and the side wall of the ceramic tile 3 is provided with a positioning groove 11. The positioning block 10 is inserted into the positioning groove 11. In this embodiment, there are several positioning blocks 10 distributed circumferentially, and there are also several corresponding positioning grooves 11. The positioning blocks 10 and the positioning grooves 11 are adapted to each other and correspond one-to-one. It should be noted that the positioning grooves 11 restrict the positioning blocks 10, thereby achieving circumferential fixation of the ceramic tile 3.

[0032] It should be further explained that during assembly, simply align the positioning block 10 with the positioning groove 11, and then place the ceramic plate 3 on the base 1 so that the positioning block 10 is inserted into the positioning groove 11. The operation is simple and the assembly is convenient.

[0033] The movable ceramic piece 4 is movably mounted on the fixed ceramic piece 3, and the linkage seat 5 is mounted on the movable ceramic piece 4. The movable ceramic piece 4 has a linkage groove 12, and the linkage seat 5 has a linkage protrusion 13. The linkage protrusion 13 is inserted into the linkage groove 12. In this embodiment, there are several linkage protrusions 13 distributed circumferentially, and there are also several corresponding linkage grooves 12. The linkage protrusions 13 and the linkage grooves 12 are adapted to each other and correspond one-to-one.

[0034] It should be noted that, through the cooperation of the linkage protrusion 13 and the linkage groove 12, the linkage seat 5 can drive the moving ceramic piece 4. During assembly, it is only necessary to align the linkage protrusion 13 with the linkage groove 12, and then place the linkage seat 5 on the moving ceramic piece 4 so that the linkage protrusion 13 is inserted into the linkage groove 12. The operation is simple and the assembly is convenient.

[0035] The end of the valve stem 6 is rotatably mounted inside the housing 2. Specifically, the housing 2 is provided with a rotating shaft 15, and the valve stem 6 is provided with a transition hole 16 that rotatably engages with the rotating shaft 15. Through the engagement of the rotating shaft 15 and the transition hole 16, the valve stem 6 can swing around the rotating shaft 15 as an axis.

[0036] The linkage seat 5 has a linkage hole 14. The end of the valve stem 6 is inserted into the linkage hole 14. When the valve stem 6 swings, it can drive the linkage seat 5 and the moving ceramic plate 4 to slide synchronously.

[0037] Both the inlet channel 7 and the outlet channel 8 pass through the base 1 and the fixed ceramic plate 3. The valve stem 6 can drive the moving ceramic plate 4 to slide through the linkage seat 5, thereby controlling the opening and closing of the inlet channel 7 and the outlet channel 8. A groove 9 is provided on the lower surface of the moving ceramic plate 4, and the groove 9 can connect the inlet channel 7 and the outlet channel 8.

[0038] The base 1 has a water inlet hole 71 and a water outlet hole 81. The fixed ceramic plate 3 has a water inlet through hole 72 and a water outlet through hole 82. The water inlet hole 71 and the water inlet through hole 72 cooperate to form a water inlet channel 7. The water outlet hole 81 and the water outlet through hole 82 cooperate to form a water outlet channel 8. The groove 9 is connected to the water outlet through hole 82. The movable ceramic plate 4 can slide to block the water inlet through hole 72 or make the groove 9 connected to the water inlet through hole 72.

[0039] It should be noted that when the valve stem 6 swings, it drives the moving ceramic plate 4 to slide through the linkage seat 5. When the moving ceramic plate 4 slides to block the water inlet hole 72, the water flowing in from the water inlet hole 71 enters the water inlet hole 72 and is blocked by the moving ceramic plate 4 and cannot pass through. Conversely, as the moving ceramic plate 4 slides, when the groove 9 is connected to the water inlet hole 72, the water flowing in from the water inlet hole 71 flows through the water inlet hole 72, the groove 9 and the water outlet hole 82 in sequence, and finally flows out from the water outlet hole 81.

[0040] Both the inlet hole 71 and the inlet through hole 72 are arc-shaped, while both the outlet hole 81 and the outlet through hole 82 are elliptical. It should be noted that, given the limited area of ​​the fixed ceramic plate 3, the arc-shaped inlet hole 71 and the inlet through hole 72, as well as the elliptical outlet hole 81 and the outlet through hole 82, can effectively increase the fluid flow area. Moreover, the arc-shaped structure can better disperse stress and reduce the risk of rupture caused by fluid pressure. The elliptical outlet hole 81 and the outlet through hole 82 can also reduce the fluid flow resistance.

[0041] The housing 2 is provided with a positioning protrusion 19. When the switch valve core is installed into the piano key shower head, the positioning protrusion 19 cooperates with the positioning groove in the piano key shower head to ensure the stability of the position of the switch valve core.

[0042] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
