Description

Technical Field

[0001] This utility model relates to the field of valve core technology, specifically to a bottom-inlet, bottom-outlet horizontally opening valve core that automatically discharges residual water. Background Technology

[0002] The swing valve core, a common accessory for faucets, is used to turn the faucet on and off, ensuring stable control of water flow. However, existing exposed shower faucets, concealed shower faucets, floor-standing bathtub faucets, and bathtub-side faucets suffer from problems such as residual water dripping from the pipes after the control valve is closed. This dripping continues until all the water in the pipes has drained, leading to issues like the pipes freezing and cracking at extremely low temperatures, and scaling on the silicone nozzles of overhead and handheld showerheads due to the retained water. These shortcomings result in unsatisfactory performance. Therefore, to avoid these drawbacks, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a bottom-inlet and bottom-outlet horizontal open valve core that is simple in structure, leak-proof, freeze-proof, and scale-proof, and can automatically discharge residual water.

[0004] This utility model is achieved through the following technical solution:

[0005] A bottom-inlet, bottom-outlet, horizontally open valve core for automatically discharging residual water includes a housing. A fixed ceramic plate and a rotating ceramic plate are installed sequentially from bottom to top on the inner side of the housing. The fixed ceramic plate has a water inlet hole, the rotating ceramic plate has a water passage hole corresponding to the water inlet hole, the fixed ceramic plate has a water outlet hole corresponding to the water passage hole, and the fixed ceramic plate has a drain hole corresponding to the water passage hole.

[0006] Furthermore, a base plate is installed at the bottom of the outer shell, and an inner water-sealing ring is provided at the connection between the base plate and the fixed ceramic sheet, and an outer water-sealing ring is provided at the bottom of the base plate.

[0007] Furthermore, the base plate is provided with a first through hole, a second through hole, and a third through hole corresponding to the water inlet hole, the water outlet hole, and the drain hole, respectively.

[0008] Furthermore, the top of the base plate is provided with a positioning post, the fixed ceramic plate is provided with a positioning groove corresponding to the positioning post, the top of the base plate is provided with a locking block, and the bottom of the outer shell is provided with a locking groove corresponding to the locking block.

[0009] Furthermore, a lever is installed on the top of the outer casing, the lever is connected to a dial, and the dial is connected to the rotating ceramic plate.

[0010] Furthermore, the lever is connected to the dial via a fixing pin.

[0011] Furthermore, the bottom of the actuating disc is provided with a connecting block, and the rotating ceramic plate is provided with a connecting groove corresponding to the connecting block.

[0012] Furthermore, a limiting block is provided on the outer side of the dial, and a limiting groove corresponding to the limiting block is provided on the inner side of the outer casing.

[0013] Furthermore, the water passage hole is elongated, and both ends of the water passage hole are fan-shaped.

[0014] Furthermore, the water inlet is arranged in a fan shape, the water outlet is arranged in a triangular shape, and the drain hole is arranged in a fan shape.

[0015] Compared to existing technologies, this invention features a rotating ceramic disc with a corresponding water inlet hole, a fixed ceramic disc with a corresponding water outlet hole, and a fixed ceramic disc with a corresponding drain hole. When the water inlet hole of the rotating ceramic disc is connected to the water inlet hole of the fixed ceramic disc, water flows normally, connecting the inlet and outlet holes. When the water inlet hole of the rotating ceramic disc is connected to the drain hole of the fixed ceramic disc, it is in a closed state. Simultaneously, the water inlet hole of the rotating ceramic disc and the water outlet hole of the fixed ceramic disc remain connected, automatically draining residual water from the water pipe. This rapid drainage prevents continuous dripping, avoids freezing and cracking of the water pipe at extremely low temperatures, and prevents scaling problems in the silicone water outlets of the overhead and handheld shower heads due to residual water. The overall performance is excellent. Attached Figure Description
