Description

Technical Field

[0001] This utility model relates to a multifunctional water valve filter, belonging to the technical field of water purification equipment. Background Technology

[0002] Existing pre-filters include: a valve head, a filter bottle connected to the upper end of the valve head, and a drainage assembly connected to the lower end of the filter bottle. A filter screen frame is installed inside the filter bottle, and a filter screen is fitted onto the outer wall of the filter screen frame. During use, water flows from the inlet of the valve head into the gap between the filter bottle and the filter screen. After being filtered by the filter screen, water flows into the center of the filter screen frame, and then from the center of the filter screen frame to the outlet of the valve head.

[0003] A water valve, commonly known as a faucet, is used to control the flow of water and has water-saving properties. Water valves are rapidly evolving, and currently used valves have relatively simple functions, such as merely controlling the water flow. Furthermore, rust and large particles can easily accumulate in tap water pipes, affecting water quality. Many households install filters on their water valves, creating valves with built-in filters. However, most of these filters are installed at the valve's outlet. While this fulfills the filtration function, different water usage scenarios require switching between purified and tap water. Current water valve technology cannot efficiently and conveniently switch between purified and tap water, thus requiring a solution to this technical problem. In addition, filter elements can become clogged after prolonged use, requiring regular cleaning. Cleaning methods include flushing the outer wall of the filter element with raw water while discharging wastewater, and flushing the outer wall of the filter element from the inside out while discharging wastewater. Backwashing is currently the mainstream direction of technological development, offering high flushing efficiency. The backwashing structure is coaxially arranged with the filter mechanism, and its opening and closing are controlled by axial movement, resulting in its widespread application. However, this application has not been found in water valve filters, especially disc filter elements. This invention solves the aforementioned technical problems by providing a multifunctional water valve filter with a more optimized structure that is easy to industrialize. It integrates the functions of switching between purified water and raw water, backwashing disc filter elements, and adjusting the tightness of the filter elements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing water valves and provide a multifunctional water valve filter. This water valve filter integrates multiple functions, including manual switching between purified water and raw water channels to meet the needs of non-water usage scenarios.
