Description

Technical Field

[0001] The utility model relates to the field of bathroom equipment, in particular to a water diversion valve with bottom water inlet and a thermostatic faucet. Background Art

[0002] The valve core is an important component of bathroom products. The water diversion valve core and the thermostatic valve core are usually installed at both ends of the thermostatic faucet. The thermostatic valve core is used to mix cold water and hot water into warm water with a constant temperature. The water diversion valve core is then used to switch different water outlets to connect with the warm water outlet of the thermostatic valve core, so that the warm water flows out from the target water outlet of the thermostatic faucet.

[0003] The existing water-dividing valve core is shown in the Chinese utility model "A water-dividing valve core and water outlet device" with patent number CN202320428736.3 (authorization announcement number CN220134677U). The valve shell of the water-dividing valve core is divided into an upper shell body and a lower end cover. The upper valve shell is provided with a plurality of side water inlets, and the bottom of the lower end cover is provided with two symmetrical water outlet channels. The valve shell of the water-dividing valve core is provided with a moving plate and a static plate. The water inlet is connected with the notch of the moving plate. The static plate is provided with a closed area, a first water outlet and a second water outlet in sequence around the circumferential direction. The rotating moving plate can connect the water inlet with the first water outlet or the second water outlet by means of the notch of the moving plate, thereby realizing the switching of water outlet of the two water paths of the water-dividing valve core. Although the water diverter valve core can allow the fluid to flow out from the target water outlet of the thermostatic faucet, the water inlet of the water diverter valve core is arranged on the side wall of the valve housing, and the water outlet is arranged at the bottom of the valve housing, so that the water outlet of the thermostatic valve core needs to be connected to the water inlet on the side of the water diverter valve core, thereby making the spatial layout of the thermostatic faucet more complicated and inconvenient for the fluid to flow in the thermostatic faucet.

[0004] In addition, the water diversion valve core is also as shown in the Chinese utility model "A water diversion valve core" with patent number CN202121029156.4 (authorization announcement number CN215172469U), in which a second water guide cavity is provided in the shell of the water diversion valve core, and the second water guide cavity is located between the shell, the rotating seat and the movable valve plate, so that the first water guide cavity is connected with the second water guide cavity, and the first water guide cavity and the second water guide cavity are connected to form a water flow buffer space. However, the second water guide cavity of the water diversion valve core will not only occupy the internal space of the water diversion valve core and increase the volume of the water diversion valve core, but also cause the water flow to flush the internal parts of the water diversion valve core, thereby accumulating impurities brought by the water flow inside the water diversion valve core, thereby affecting the use effect of the water diversion valve core.
