Description

Technical Field

[0001] This utility model relates to a disc adjustment mechanism for a water valve filter and a horizontally stacked disc 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 only 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 horizontal disc water valve filters, especially disc filter elements. This invention solves the aforementioned technical problems by providing a more optimized structure and easily industrialized disc adjustment mechanism for a water valve filter, as well as a horizontal disc water valve filter, integrating the functions of switching between purified water and raw water, and backwashing the filter screen. Utility Model Content

This invention provides a disc adjustment mechanism for a water valve filter, which allows for manual switching between purified water and raw water channels to meet the needs of non-water use scenarios. Simultaneously, it can switch to a backwashing and sewage discharge mode to adjust the tightness of the filter element, achieving reverse flushing of the filter element, extending the service life of the water valve, and improving its performance.

[0005] The second objective of this invention is to address the shortcomings of existing technologies by providing a horizontally mounted disc water valve filter that employs the disc adjustment mechanism of the aforementioned water valve filter. This water valve filter allows for manual switching between purified water and raw water flow channels to meet the needs of non-water usage scenarios. It can also switch to a backwashing mode to adjust the tightness of the filter elements, enabling backwashing of the filter screen, extending the lifespan of the water valve, and improving its performance.
