透氣閥結構改良 Improved ventilation valve structure

本創作有關用於設備外殼的透氣閥，特別是一種兼具防水防塵功能之透氣閥結構改良。 This invention relates to a breathable valve used for equipment casing, especially an improvement in the structure of the breathable valve that has both waterproof and dustproof functions.

一般精密的設備往往會設置有外殼來提升防護效果，讓內部的本體能更保久地運用，而為了解決內外通風散熱、壓差調節等問題，以往多係在外殼開設有通風孔或留下可通風的間隙，但由於無法避免較小的塵埃與水珠進入內部損及設備本體，本案創作人早年開發有一種防水防塵透氣閥結構，並提出有中華民國專利申請號第100217832號專利，藉由此透氣閥達到讓進出的氣體均可透過該防水防塵透氣元件防止塵埃與水氣進入內部的效果。 Generally, precision equipment is often equipped with a shell to improve the protective effect and ensure that the internal body can be used longer. In order to solve problems such as internal and external ventilation, heat dissipation, and pressure difference adjustment, in the past, ventilation holes were often provided in the shell or left There is a gap for ventilation, but since it is unavoidable to prevent small dust and water droplets from entering the interior and damaging the device body, the author of this case developed a waterproof and dustproof breathable valve structure in the early years, and filed the Republic of China Patent Application No. 100217832. This breathable valve has the effect of allowing incoming and outgoing gases to pass through the waterproof, dustproof and breathable element to prevent dust and moisture from entering the interior.

然，創作人在近年來的實際應用中發現，前述之防水防塵透氣閥雖能幫助設備維持效能與提高壽命，但用以輔助防水防塵透氣元件固定的黏膠，在某些特殊的應用環境中不免會發生有脫膠的情形，諸如應用在油氣含量較高的環境，容易受油氣腐蝕而脫膠，進而影響其防水防塵效能，使得透氣閥未能達到預期的效果或使用期限；有鑑於此，創作人再行鑽研改進之道，經不斷嘗試與試驗，完成有本創作。 However, the creators have found in practical applications in recent years that although the aforementioned waterproof, dustproof and breathable valves can help the equipment maintain performance and extend its life, the adhesive used to assist in fixing the waterproof, dustproof and breathable components cannot be used in certain special application environments. Degumming will inevitably occur, such as when used in an environment with a high oil and gas content. It is easily corroded by oil and gas and degummed, which in turn affects its waterproof and dustproof performance, causing the breathable valve to fail to achieve the expected effect or service life. In view of this, the creation People continue to delve into ways of improvement, and through continuous attempts and experiments, they complete original creations.
