Description

Technical Field

[0001] The invention relates to a horizontally placed laminated water valve filter and a control method thereof, belonging to the technical field of water purification equipment and control methods. Background Art

[0002] Conventional prefilters include a valve head, a filter bottle connected to the valve head at its upper end, and a drainage assembly connected to the lower end of the filter bottle. A filter screen frame is located within the filter bottle, and a filter screen is sheathed around the outer wall of the filter screen frame. During use, water flows from the valve head's water inlet into the gap between the filter bottle and the filter screen, is filtered by the filter screen, and then flows into the center of the filter screen frame. From there, it flows to the valve head's water outlet.

[0003] Water valves are commonly known as faucets, which are used to control the size of water flow and have the effect of saving water. Water valves are updated very quickly. The functions of the water valves currently used are relatively simple, such as only controlling the size of the water flow. At the same time, rust residue and large particles of impurities are easily generated in the tap water pipes, which affect the water quality. Many families will install filtering devices on the water valves, thus forming water valves with filtering functions. However, most of the filtering devices with filtering functions are installed at the water outlet of the water valve. Although it meets the filtering function of the water valve, different water use scenarios require switching between purified water and raw water. The water flow channel of the water valve in the existing technology cannot achieve efficient and convenient switching between purified water and raw water, so this technical problem needs to be solved. In addition, the filter element will become clogged after long-term use, so it needs to be cleaned regularly. The cleaning methods include flushing the outer wall of the filter element with raw water while draining the sewage, and backwashing the outer wall of the filter element from the inside to the outside while draining the sewage. Among them, backwashing is the mainstream direction of current technical research and development, with high flushing efficiency. The backwashing structure is coaxially arranged with the filter mechanism, and the opening and closing of the backwashing structure is controlled by axial movement. It has been well applied, but such application has not been found in the horizontal laminated water valve filter, especially the laminated filter element. The present invention solves the above-mentioned technical problems and provides a horizontal laminated water valve filter with a more optimized structure and easy industrialization. It integrates the switching of purified water and raw water, as well as the functions of backwashing the laminated filter element and adjusting the tightness of the filter element.
