Description

Technical Field

[0001] This utility model relates to a valve core, specifically a three-inlet, two-outlet switching valve core used for switching between purified water and running water output. Background Technology

[0002] The use of a faucet mainly involves operating a switch valve core via a handle to switch the water flow on and off. However, since a single switch valve core can only provide one water flow mode, if a water-using application requires two different water output functions (such as simultaneously providing purified water and fresh water), it is necessary to add another switch valve core to the faucet, or even install two faucets directly. This significantly increases the complexity and difficulty of the overall pipeline layout, resulting in high installation costs and inconvenience in use.

[0003] Therefore, how to develop and improve the existing structure to address its shortcomings in practical use is a goal that the relevant industry needs to strive for. In view of this, the creator came up with the idea of ​​creation and designed it based on many years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, this utility model was launched. Utility Model Content

[0004] Technical issues to be addressed:

[0005] The existing switching valve core can only be used for one water flow mode, which is the technical problem to be solved.

[0006] Technical characteristics of the problem-solving process:

[0007] This utility model provides a three-input, two-output switching valve core. The switching valve core comprises a rotating seat assembled within a valve housing. Below the rotating seat, inside the valve housing, are a movable valve plate and a fixed valve plate stacked sequentially. A valve stem extending upwards from the center of the rotating seat extends from the valve housing. The rotating seat engages the movable valve plate, allowing the movable valve plate to rotate via the rotating seat when the valve stem is operated. A valve seat below the valve housing prevents the fixed and movable valve plates from falling out. The valve housing contains… The valve body has a chamber with an upper port. The rotating seat, the movable valve plate, and the fixed valve plate are placed in the chamber of the valve body. The upper port allows the valve stem to pass through the valve body upwards. The bottom surface of the movable valve plate is recessed to form a first water passage chamber and a second water passage chamber. The first water passage chamber is Y-shaped. The fixed valve plate has a raw water outlet hole in its center. Outside the raw water outlet hole, there is a raw water inlet hole, a clean water inlet hole, a fresh water inlet hole, and a clean and fresh water outlet hole. The valve seat has multiple flow holes of the same number at the corresponding positions of the raw water outlet, raw water inlet, purified water inlet, fresh water inlet, and purified fresh water outlet. When the rotating seat, the movable valve plate, and the fixed valve plate, which are housed in the chamber, are stacked sequentially, the valve seat, through which the valve body and the valve seat are joined, provides support for the fixed valve plate, the movable valve plate, and the rotating seat. In addition to securing the fixed valve plate to the top surface of the valve seat, the flow holes also allow for connection of the pipe body. The raw water inlet and outlet of the fixed valve plate can be connected to a water source and a water purifier, respectively. By using two pipes, the purified water outlet and fresh water outlet of the water purifier can be smoothly reconnected to the purified water inlet and fresh water inlet, respectively. The purified and fresh water outlet of the fixed valve plate is connected to a water outlet device through the flow hole of the valve seat. The same switching valve core provides operation, and the water outlet device can switch between filtered water and fresh water. Thus, a three-inlet and two-outlet switching valve core is obtained.

[0008] Compared to the effectiveness of previous technologies:

[0009] This utility model provides a three-inlet, two-outlet switching valve core, which can achieve the switching between purified water and fresh water simultaneously with the same water outlet device using the switching valve core, making the installation and piping of the water outlet device simpler and less complicated, and more convenient to use.
