[0002] The valve core is the main accessory of the faucet. By turning the valve core rod, the faucet water flow can be controlled to close and increase or decrease.

[0003] The sealing performance of the faucet valve core rotating rod, the valve core housing and the valve cover in the prior art is poor. After the valve core has been rotated for a period of time, leakage is prone to occur at the connection between the valve cover and the rotating rod, and at the connection between the valve core housing and the rotating rod, thereby affecting the service life of the valve core. Although the sealing performance of the existing valve core is increased by using a sealing ring, the sealing ring may fall off after the rotating rod is rotated multiple times. Therefore, the applicant has designed and proposed a faucet valve core with good sealing performance and anti-ring falling off. Summary of the invention

[0004] The utility model provides a faucet valve core with good sealing performance and an anti-ring disengagement function, aiming to improve the technical problem that after a period of rotation and use of the existing valve core, leakage is prone to occur at the connection between the valve cover and the rotary rod, and at the connection between the valve core housing and the rotary rod.

[0009] Furthermore, the static plate is symmetrically provided with second flow holes matching the first flow holes.

[0010] Beneficial effects:

[0011] After the valve core of the present utility model is assembled, the first annular sealing groove and the first annular sealing protrusion are mutually engaged, and the second annular sealing groove and the second annular sealing protrusion are mutually engaged, greatly increasing the sealing performance at the connection between the valve core housing and the rotating rod, solving the problem of easy leakage at the connection between the valve core housing and the rotating rod, and improving the service life of the valve core; at the same time, through the design that the connection between the rotating rod and the valve cover is provided with an annular fixing groove for fixing the feeler ring, the feeler ring is tightly fixed at the connection between the valve cover and the rotating rod, thereby increasing the sealing performance at the connection between the rotating rod and the valve cover, so as to achieve the effect of overall improvement of the valve core sealing performance and prevention of the feeler ring from falling off, and the feeler ring is made of polyvinyl chloride material, with a higher hardness than the rubber material of the sealing ring, making the opening and closing feel of the valve core lighter and smoother, protecting the faucet ceramic piece, thereby reducing the wear between the ceramic piece and the valve core.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0021] For the embodiments, please refer to Figures 1 to 6 , the first embodiment of the present utility model provides an anti - detachment faucet valve core with good sealing performance, and the structure includes a rotating rod main body 1, a valve core housing 2, a rotating piece 3, a static piece 4, a sealing base 5, a feeler ring 6 and a valve cover 7. It is characterized in that: at the internal connection of the rotating rod main body 1 and the valve core housing 2, there are a first annular sealing groove 102 and a second annular sealing groove 103. On the inner side of the valve core housing 2, there is a first annular sealing protrusion 201 that cooperates with the first annular sealing groove 102, and a second annular sealing protrusion 202 that cooperates with the second annular sealing groove 103. Specifically, at the lower end of the rotating rod main body 1, there are symmetrically arranged rotating protrusions 104 that cooperate with the rotating piece 3.

[0022] Meanwhile, at the cooperating connection of the rotating rod main body 1 and the valve cover 7, there is an annular fixing groove 101 for fixing the feeler ring 6. Through the design of the annular fixing groove and the feeler ring, the feel of the valve core switch is made lighter and smoother, protecting the faucet ceramic piece, thereby reducing the wear between the ceramic piece and the valve core.

[0023] Furthermore, on the rotating piece 3, there are symmetrically arranged rotating grooves 301 that cooperate with the rotating protrusions 104. On the rotating piece 3, there are also symmetrically arranged first flow holes 302. On the static piece 4, there are symmetrically arranged second flow holes 401 that cooperate with the first flow holes 302.

[0024] Specifically, the working principle of the good sealing performance of the valve core in this embodiment after assembly is as follows:

[0025] 1. By the mutual engagement of the first annular sealing groove 102 and the first annular sealing projection 201, and the mutual engagement of the second annular sealing groove 103 and the second annular sealing projection 202, the sealing performance at the connection between the valve core housing and the rotating rod is greatly enhanced, solving the problem of easy leakage at the connection between the valve core housing and the rotating rod, and improving the service life of the valve core.

[0026] 2. Through the design of the annular fixing groove 101 for fixing the feeler ring 6 provided at the connection between the rotating rod 1 and the valve cover 7, the feeler ring 6 is tightly fixed at the connection between the valve cover and the rotating rod, thereby increasing the sealing performance at the connection between the rotating rod and the valve cover 7. Moreover, since the feeler ring 6 is made of polyvinyl chloride and has a higher hardness than the rubber material of the sealing ring, the feel of opening and closing the valve core is made smoother and lighter, protecting the faucet ceramic chip, and thus reducing the wear between the ceramic chip and the valve core.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
