Description

Technical Field

[0001] The invention belongs to the technical field of valve cores, and in particular to a synchronous on-off bottom water inlet three-switch drainage valve core. Background Art

[0002] Thermostatic faucets are widely used in people's daily lives. Thermostatic faucets have the function of outputting cold water, hot water and mixed water. The valve core is an important component of the thermostatic faucet. The valve core is a valve part that the valve body uses its movement to achieve the basic functions of direction control, pressure control or flow control. Among them, the hot and cold water ceramic valve core is the most common valve core component on the market to control the water output status. Usually, the water output of the hot and cold water ceramic valve core is achieved by the user to toggle the joystick. The user toggles the joystick to one side to achieve water output, and toggling it in the opposite direction reduces the water output.

[0003] At present, the China Patent Network discloses a three-function water-dividing valve core ceramic piece with a synchronous switch [authorization announcement number: CN109027316B], including a ceramic moving piece and a ceramic fixed piece, the ceramic moving piece is connected to the rotating seat of the water-dividing valve core, the ceramic fixed piece is fixed to the base of the water-dividing valve core, the ceramic fixed piece is provided with three independent mixed water outlet holes, a cold water inlet hole, a cold water outlet hole and a blocking surface, a mixed water inlet hole is provided on the ceramic moving piece, the mixed water inlet hole is blocked by the blocking surface, and the ceramic moving piece is provided with a pair of The arc-shaped cold water inlet groove of the cold water inlet hole forms a closing block corresponding to the cold water outlet hole, and the ceramic plate is rotated. When the closing block of the ceramic movable plate blocks the cold water outlet hole of the ceramic stator, the sealing surface of the ceramic stator blocks the mixed water inlet hole of the ceramic movable plate, thereby cutting off the cold water path and the mixed water path. When the mixed water inlet hole of the ceramic movable plate is rotated to the position where the mixed water outlet hole of the ceramic stator is respectively connected to the mixed water outlet hole of the ceramic stator, the cold water inlet groove of the ceramic movable plate is always connected to the cold water inlet hole of the ceramic stator, thereby realizing the conduction of the cold water path and the conduction of the mixed water path.

[0004] The valve core is installed in a thermostatic faucet for use. The thermostatic faucet is generally installed in a shower product for use. During use, when the thermostatic faucet is closed, water accumulates in the entire faucet cavity and the shower product pipeline, so the following problems may occur: 1. The accumulated water in the faucet is used by other water outlets in the home. When the water in the pipeline flows, air is injected into the shower faucet with accumulated water. The accumulated water in the shower faucet cavity will drip onto the ground, making a sound and causing water to accumulate on the originally clean ground, which greatly reduces the user experience; 2. The longer the water accumulates in the faucet cavity and the shower product pipeline, the more likely it is that bacteria will breed in the accumulated water, metal parts will rust, the accumulated water will stink, and scale will be produced. When in use, the water with bacteria will be sprinkled on the user's skin, posing a great safety hazard to human health; 3. In northern regions, the accumulated water in the faucet cavity and the shower product pipeline is prone to freezing. After freezing, the accumulated water increases in volume, which in turn causes the faucet and pipeline to be cracked, causing damage to the faucet and shower product. Summary of the invention
