TECHNICAL FIELD

[0001] The utility model relates to a water outlet valve, in particular to an improved bounce valve core of water outlet valve, belong to sanitary fittings technical field. BACKGROUND

[0002] The bottom of wash basin and bathtub and other sanitary wares is provided with a water outlet hole, and a water outlet valve is arranged in the water outlet hole. The simplest structure of the existing water outlet valve is a valve, and a sealing ring is embedded in the valve. The sealing ring cooperates with the water outlet hole. The valve is manually operated to open and close the water outlet hole. The valve structure is simple, and the cost is low. However, the sealing ring is easy to wear and tear, the sealing performance is poor, the water outlet hole is not completely closed, and water seepage may occur. Another type of water outlet valve is a press-type bounce valve core. For example, a utility model patent CN215166206U with the patent name of "a water outlet and its bounce valve core" is provided. The bounce valve core includes a bounce shell and a bounce core. The bounce shell and the elastic core slide relative to each other. The bounce valve core also includes a pull rod hook. The pull rod hook is hinged to the bounce shell. The bounce core is provided with a sliding groove. The pull rod hook is hooked on the upper end of the bounce shell and is limited by a locking spring that is sleeved on the upper end of the bounce shell. The end of the pull rod hook that is away from the hinge axis is embedded in the sliding groove and cooperates with the sliding groove to adjust the total length between the bounce shell and the bounce core. The end of the bounce shell that is close to the bounce core is fixed with a permanent magnet one. The end of the bounce core that is close to the bounce shell is fixed with a permanent magnet two. The end faces of the permanent magnet one and the permanent magnet two that are close to each other have the same magnetic pole. The existing structure has the following disadvantages: the pull rod hook is hooked on the upper end of the bounce shell and is limited by the locking spring that is sleeved on the upper end of the bounce shell. When the water outlet is used for a long time or is pressed quickly for many times, the locking spring is easy to fall off. The limiting reliability of the pull rod hook is poor. Once the locking spring falls off, the pull rod hook will be pulled out of the water outlet, which shortens the service life.
