Description

Technical Field

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

[0002] The valve core, a common accessory in faucets, is used to turn the faucet on and off, ensuring stable control of water flow. However, in existing faucets, residual water remains in the pipes after the control valve is closed, leading to several problems: 1. Prolonged water retention in the pipes fosters bacterial growth, causing skin irritation and other adverse effects on skin health upon reuse. 2. In showerheads, when full of water, dripping can occur due to imbalances or air intake, 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, creating a poor 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 bottom-inlet and bottom-outlet side drain 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 valve core with bottom inlet and bottom outlet includes a lower shell. A fixed ceramic plate and a movable ceramic plate are installed sequentially from bottom to top on the inner side of the lower shell. The movable ceramic plate and the fixed ceramic plate are slidably connected. The fixed ceramic plate has a water inlet hole in the middle. The movable ceramic plate has a water passage hole corresponding to the water inlet hole. One side of the fixed ceramic plate has a water outlet hole corresponding to the water passage hole. The other side of the fixed ceramic plate has a drain hole corresponding to the water passage hole.

[0006] Furthermore, an upper shell is installed on the top of the lower shell, a lever is installed on the inner side of the upper shell, a lever sleeve is slidably connected to the bottom of the lever, the lever sleeve is connected to the movable ceramic plate, and the lever sleeve is slidably connected to the bottom of the upper shell.

[0007] Furthermore, the lower shell has a positioning block at its top, the upper shell has a positioning groove corresponding to the positioning block, the lower shell has a slot at its top, and the upper shell has a locking block corresponding to the slot.

[0008] Furthermore, the lever is rotatably connected to the upper shell via a fixing pin, the bottom of the lever is provided with a lever post, and the top of the lever sleeve is provided with a lever groove corresponding to the lever post.

[0015] Compared to existing technologies, this utility model features a movable ceramic plate with a water inlet corresponding to the water inlet, a fixed ceramic plate with a water outlet corresponding to the water inlet on one side, and a drain hole corresponding to the water inlet on the other side. When the water inlet of the movable ceramic plate is connected to both the water outlet and the water inlet of the fixed ceramic plate, water flows normally. When the water inlet of the movable ceramic plate is connected to both the water outlet and the drain hole of the fixed ceramic plate, it is in a closed state, which is also a draining state. Due to the gravity of the water, residual water in the pipe is automatically discharged, achieving immediate drainage of residual water.
