Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, specifically to a gas supply valve. Background Technology

[0002] Existing oxygen-supplying pillows typically employ a design with a single oxygen supply tube inside the pillow, utilizing the pillow's breathability to achieve diffused oxygen delivery. However, this single-tube oxygen supply method has significant technical limitations: firstly, because oxygen is output through only a single tube, the oxygen supply area is too concentrated, making it difficult to achieve zoned oxygen supply within the pillow; secondly, the single-tube oxygen supply mode easily leads to uneven oxygen distribution on the head and back surface of the pillow, affecting the user's breathing comfort.

[0003] To address the aforementioned issues, the industry has proposed a solution using multiple parallel oxygen supply lines. Theoretically, this design can achieve both zoned oxygen supply to the pillow and ensure uniform oxygen distribution across the headrest surface through the coordinated operation of multiple lines. However, the practical application of this technology faces a critical technical bottleneck: the lack of dedicated gas path control valves for multi-line systems means that existing valve structures cannot independently control the on / off state of multiple lines. This lack of valve technology severely restricts the functionality and clinical application of multi-line oxygen supply pillows. Therefore, there is an urgent need to design a valve capable of controlling the on / off state of multiple lines, allowing for flexible control of each line's flow and providing reliable technical support for oxygen supply pillows to achieve diverse functions such as zoned and uniform oxygen supply.
