[0016] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0017] See also Figure 1-4The utility model provides an embodiment: a new water-dividing switch valve core, comprising a valve seat 7 and a valve cover 1 installed on the valve seat 7; a driving part 4 is also provided between the valve cover 1 and the valve seat 7; one end of the driving part 4 is linked with a valve stem 2, and the other end of the valve stem 2 passes through the valve cover 1 and is exposed outside the valve cover 1; a plug hole 11 with a polygonal cross section is provided on a side of the valve stem 2 facing the driving part 4, and a latch 5 matched with the plug hole 11 is provided on a side of the driving part 4 facing the valve stem 2.

[0018] In summary, since the device utilizes the matching connection between the plug 5 and the socket 11, the valve stem 2 and the driving part 4 can be directly linked, so that the power between the valve stem 2 and the driving part 4 can be reliably transmitted, and the number of parts between the valve stem 2 and the driving part 4 can be reduced, which is conducive to reducing the production cost of the device. In particular, the valve stem 2 can be directly sleeved on the driving part 4 through the socket 11, so that not only the assembly efficiency between the valve stem 2 and the driving part 4 is further improved, but also the assembly process and assembly steps are greatly optimized.

[0019] In addition, in order to prevent the valve stem 2 from axially sliding in the valve cover 1, that is, sliding upward or downward along the central axis of the valve cover 1, a support ring 12 is further provided on the side of the valve stem 2 facing the driving part 4, and the support ring 12 extends radially outwardly along the valve stem 2. Therefore, the support ring 12 can be used to expand the outer diameter of the valve stem 2, and when the valve cover 1 is connected to the valve seat 7, the support ring 12 contacts the inner bottom surface of the valve cover 1 to prevent the valve stem 2 from sliding.

[0020] Furthermore, since a support pad 3 is provided between the facing surfaces of the support ring 12 and the valve cover 1, the support pad 3 can be used to pad the connection between the support ring 12 and the valve cover 1, which can further prevent the valve stem 2 from sliding; and can also be used to fill the gap between the two to improve the sealing of the device. The support pad 3 is preferably a sealing ring.

[0021] On the basis of the above solution, in order to improve the feel of the device when in use, the drive part 4 is further provided with a mounting cavity 6, and a pin 9 is provided in the mounting cavity 6. Therefore, the pin 9 is in contact with the inner wall of the valve cover 1 to enhance the rotation resistance of the drive part 4, thereby improving the feel of the device when it is opened. At the same time, the increase in resistance can avoid the problem of the valve core opening due to accidental contact.

[0022] Furthermore, since a spring 8 is also provided in the installation cavity 6, and the spring 8 causes one end of the pin 9 to contact the valve cover 1, the resistance between the pin 9 and the inner wall of the valve cover 1 is greater, which can further reduce the problem of the valve core opening due to accidental contact.

[0023] At the same time, since the inner wall surface of the valve cover 1 is also provided with a plurality of retaining grooves 10 with the same structure, when the pin 9 is inserted into the retaining groove 10, the phenomenon of the device opening due to accidental contact can be completely prevented. In addition, the end of the pin 9 is a spherical surface, and the setting of the spring 8 allows the pin 9 to freely expand and contract in the installation cavity 6. When the valve stem 2 is manually rotated, the pin 9 can slide out of the retaining groove 10. When the valve stem 2 continues to rotate and the pin 9 contacts another retaining groove 10, the spring 8 prompts the pin 9 to hit the valve cover 1, and the device can make a "da da da" sound when in use, which can not only improve the feel of the device when in use, but also make a sound.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
