Description

Technical Field

[0001] This utility model relates to the field of valve core technology, specifically to an automatic drainage side-inlet bottom-outlet water distribution valve core. Background Technology

[0002] The diverter valve core, a common accessory for faucets, is used to switch the faucet on and off; hence, it's also called a switching valve core or on / off valve core. However, with existing faucets, residual water doesn't drain from the pipes after the control valve is closed, leading to several problems: 1. Prolonged water retention in the pipes breeds bacteria, causing skin irritation and other adverse effects on skin health upon reuse. 2. In showerheads, when full of water, dripping can occur due to imbalance or air ingress, creating a rattling sound that disturbs the user's rest and results in unsanitary conditions like water accumulation on the bathroom floor. 3. Each time the faucet is turned on, a large amount of residual cold water in the pipes results in a chilly shower, especially in winter, leading to a poor user experience. 4. In cold northern regions, water pipes full of water are prone to freezing and cracking when the water freezes. Therefore, to avoid these shortcomings, 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 an automatic drainage side-inlet bottom-outlet water distribution valve core that is simple in structure, prevents bacterial growth, prevents dripping, prevents freezing and cracking, and provides a good user experience.

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

[0005] An automatic drainage side-inlet bottom-outlet water distribution valve core 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 rotating ceramic plate has a water inlet hole on its side. The fixed ceramic plate has a water outlet hole corresponding to the water inlet hole. The rotating ceramic plate has a water passage hole corresponding to the water outlet hole. The fixed ceramic plate has a drain hole corresponding to the water passage hole. The housing has a water inlet that communicates with the water inlet hole.

[0006] Furthermore, there are two water outlets, which are respectively located on the left and right sides of the drain hole.

[0007] 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.

[0008] Furthermore, the base plate is provided with a first through hole and a second through hole corresponding to the water outlet and the drain hole, respectively.

[0009] 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.

[0010] Furthermore, a lever sleeve is rotatably connected to the top of the outer casing, the lever sleeve is connected to a lever, and the lever sleeve is connected to the rotating ceramic plate.

[0011] Furthermore, the lever is connected to the lever sleeve via a fixing pin.

[0012] Furthermore, the bottom of the lever sleeve is provided with a connecting block, and the rotating ceramic plate is provided with a connecting groove corresponding to the connecting block.

[0013] Furthermore, a first O-ring is fitted on the outer side of the lever sleeve, and a second O-ring is fitted on the outer side of the outer shell.

[0014] Furthermore, the water inlet is funnel-shaped, the water outlet is fan-shaped, the water passage is fan-shaped, and the drain is circular.

[0015] Compared to existing technologies, this invention features a water inlet on the side of a rotating ceramic plate, a water outlet corresponding to the water inlet on a fixed ceramic plate, a water passage corresponding to the water outlet on the rotating ceramic plate, and a water drain corresponding to the water passage on the fixed ceramic plate. The outer casing has a water inlet connected to the water inlet. When the water inlet of the rotating ceramic plate and the water outlet of the fixed ceramic plate are connected, normal water flow occurs, simultaneously draining residual water from the other water outlet. When the water inlet of the rotating ceramic plate and the water outlet of the fixed ceramic plate are not connected, the system is closed. In this case, the water passage of the rotating ceramic plate and the water outlet of the fixed ceramic plate are connected. The ceramic tile's drain hole and two outlet holes are all interconnected. When in drainage mode, residual water in the pipes is automatically discharged due to gravity, achieving immediate drainage of residual water. This prevents residual water from lingering for extended periods, thus avoiding bacterial growth and skin irritation. It also prevents continuous dripping, avoiding unsanitary conditions like water accumulation on the bathroom floor, and prevents a poor initial user experience in winter due to large amounts of residual cold water in the pipes. Furthermore, it prevents the outlet pipes from freezing and cracking at extremely low temperatures, resulting in excellent performance. Attached Figure Description
