Description

TECHNICAL FIELD

[0001] The utility model relates to the faucet valve core equipment technical field more particularly, it is a kind of valve core structure of anti-falling. BACKGROUND

[0002] At present, the valve core of water faucet on the market is fixed in the elbow by threaded connection, the valve stem of valve core is connected with the handle at the top, and the handle can be pulled left and right to drive the valve core to open or close, realizing the opening and closing of water faucet. The threaded connection has the following disadvantages: under the condition of long-term use, the handle is pulled left and right, which can cause the ceramic piece at the bottom of valve stem and valve core to loosen, and the valve may fail, which is a common fault of most water faucets and needs to be replaced. In addition, when the water faucet is opened and closed, the abutting block at the bottom of valve stem continuously rubs against the ceramic piece, which can cause the gap between valve stem and ceramic piece to become larger after a long time, resulting in the phenomenon of tight closing and water leakage. Therefore, we propose a valve core structure that prevents falling, which sets a protective cover on the top of ceramic piece, the protective cover is made of copper material and abuts against the valve stem. Long-term use will not cause wear and tear, which can prevent the loosening between valve stem and ceramic piece and tooth loss, greatly prolonging the service life of water faucet.

[0003] In order to improve the fitting degree between valve stem and ceramic sleeve, improve the wear resistance of valve core, and prevent the falling between valve stem and ceramic sleeve, Chinese patent (grant announcement number: CN209414654U) discloses a high-strength anti-falling wear-resistant valve core, which comprises a shell, a valve stem, a valve stem seat, a ceramic fixed frame, a ceramic movable sleeve, a ceramic fixed sleeve and a valve seat. The upper end of the ceramic movable sleeve is provided with a sealing groove, and further comprises a sealing cover and a sealing ring. The opening of the sealing cover is arranged in the sealing groove, and the sealing ring is arranged between the end faces opposite to each other of the ceramic fixed frame and the ceramic movable sleeve. When the inner parts are loose or worn, the gap between the ceramic fixed frame and the ceramic movable sleeve can be eliminated by the elastic expansion of the sealing cover and the sealing ring, thereby improving the wear resistance of the valve core and preventing the falling between the ceramic fixed frame and the ceramic movable sleeve.

[0004] The scheme still has some deficiencies in application. Since the valve stem of valve core and the ceramic often rub against each other when the water faucet is opened and closed, good abutment needs to be achieved every time, otherwise it is easy to cause tight closing and water leakage. Although the rubber ring and the rubber sleeve have a certain sealing function, they can be easily worn out after a long time of friction, which also causes tight closing. At the same time, long-term friction between valve stem and ceramic can also easily cause the ceramic sleeve to wear out, and long-term wear can cause tooth loss with valve stem. Therefore, the structure of valve core needs to be improved to enable valve stem and ceramic sleeve to remain tightly fitted for a long time, so as to avoid wear and tear and gap, and prolong the service life of water faucet.
