[0031] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0032] like Figure 1 As shown, it is a schematic diagram of an independent detachable gear rotating core involved in the present invention, when it is assembled together with the outer shell 60 and the inner core 70 in the valve core.

[0033] like Figures 2 to 5 As shown, it is an independent and detachable gear rotation core involved in the present invention, including a shell 10, a core body 20, a dividing plate 30, a marble 40 and a limiting plate 50.

[0034] The housing 10 has an axial hole 11 extending therethrough in the axial direction, a connecting groove 12 for the limiting piece 50 to pass through from outside to inside, and an annular receiving groove 13 for the marble 40 to be disposed.

[0035] The core body 20 has a shaft rod 21 inserted into the shaft hole 11 and a limiting groove 22 formed on the shaft rod 21 for cooperating with the limiting plate 50 . The limiting groove 22 is used to limit the axial displacement of the core body 20 relative to the housing 10 .

[0036] The indexing plate 30 is sleeved on the shaft 21 and is formed with a plurality of gear slots 31 . The marbles 40 abut against or are separated from the gear slots 31 when the housing 10 and the core 20 rotate relative to each other.

[0037] Thus, the present invention relates to an independently detachable gear rotating core, whose shell 10 can be assembled and connected with the outer shell 60 of the valve core, and whose core body 20 can be assembled and connected with the inner core 70 of the valve core, that is, the shell 10 and the outer shell 60 of the valve core can keep rotating synchronously, and the core body 20 and the inner core 70 of the valve core can keep rotating synchronously, and the "click" sound emitted when the internal marble 40 is facing the gear slot 31 on the dividing plate 30 is used as the gear prompt sound, thereby realizing the gear reminder function.

[0038] Compared with the prior art, the present invention makes the gear prompt function into an independent component, so that it can be assembled at any time according to the current needs of customers. For the original valve core, no changes are needed, that is, the two valve cores with and without the gear prompt function are integrated together, which greatly reduces the production cost and realizes personalized service for customers.

[0039] like Figures 1 to 3 As shown, as a specific embodiment, the housing 10 further has coupling teeth 14, and the coupling teeth 14 are used to engage with the outer shell 60 to allow the housing 10 and the outer shell 60 to rotate synchronously.

[0040] like Figures 2 to 5 As shown, the core body 20 also has a flange 23 and an elastic clamping point 24. The flange 23 is formed at one end of the shaft 21 and is used to be sealed and connected with the housing 10, and the elastic clamping point 24 is formed at the other end of the shaft 21 and is used to clamp with the inner core 70. In addition, in order to make it easier for the shaft 21 and the inner core 70 to rotate synchronously, the cross section of the shaft 21 is a hexagonal shape that matches the inner core 70, so that the shaft 21 can maintain synchronous rotation after being directly inserted into the inner core 70.

[0041] In order to achieve sealing effect, Figure 2 and Figure 3 As shown, the present invention at least includes a first sealing ring 25 and a second sealing ring 26 . The first sealing ring 25 is sleeved on the flange 23 , so as to seal the gap between the flange 23 and the housing 10 .

[0042] The second sealing ring 26 is used to seal the gap between the shaft 21 and the housing 10. It is sleeved on the shaft 21, specifically between the limiting groove 22 and the dividing plate 30. In this way, the first sealing ring 25 and the second sealing ring 26 can achieve a better sealing effect.

[0043] like Figure 2 and Figure 3As shown in the figure, as a specific embodiment of the indexing plate 30 and the core body 20 maintaining synchronous rotation, the indexing plate 30 is further formed with a locking groove 32, and the core body 20 is further provided with a locking tooth 27 formed on the shaft 21 for cooperating with the locking groove 32. In this way, the indexing plate 30 and the core body 20 are always kept in synchronous rotation by utilizing the locking connection between the locking tooth 27 and the locking groove 32.

[0044] like Figure 4 As shown, in order to reduce the noise generated by the water flow, a plurality of silencer grooves 28 are formed on the flange 23 .

[0045] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
