Description

Technical Field

[0001] This utility model relates to a water valve filter head structure with flow channel switching and a horizontally placed 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 flow rate. Furthermore, rust and large particles easily accumulate in tap water pipes, affecting water quality. Many households install filters on their water valves, creating water 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 raw water. Existing water valve technology cannot efficiently and conveniently switch between purified and raw water, thus requiring a solution. This invention solves the aforementioned technical problem by providing a more optimized structure and an industrially feasible water valve filter head structure with flow channel switching, as well as a horizontally positioned water valve filter. Utility Model Content

[0004] One of the objectives of this invention is to address the shortcomings of existing water valves by providing a water valve filter head structure with flow channel switching. This head structure can efficiently and conveniently switch between purified water and raw water flow channels to meet the needs of water valve filters in non-water use scenarios.

[0005] The second objective of this invention is to address the shortcomings of existing water valves by providing a horizontally positioned water valve filter that employs the aforementioned valve head structure. This horizontally positioned water valve filter allows for manual switching between purified water and raw water flow channels, and its horizontal orientation optimizes the assembly layout, making it well-suited for different installation locations and saving vertical assembly space.

It switches between modes by rotating relative to each other. Rotating clockwise from the initial position switches to the second mode, and rotating counterclockwise from the initial position switches to the third mode.
