Description

本考案は、機器のシェルに使用される通気弁、特に防水防塵機能を備えた通気弁の構造改良に関する。 TECHNICAL FIELD The present invention relates to a structural improvement of a vent valve used in a device shell, particularly a vent valve with waterproof and dustproof functions.

一般に、精密機器は、往々にしてシェルを設けて保護効果を向上させており、内部の本体をより永続的に運用可能にさせ、内外の通気及び放熱、圧力差調整等の問題を解決するために、従来、多くは通気孔がシェルに開設されるか、通気可能な隙間が残されていたが、比較的小さな灰塵及び水滴が内部に進入して機器本体を損傷させることを回避できないため、本考案者は、初期に防水防塵の通気弁構造を開発し、中華民国特許出願第100217832号を提出しており、この通気弁によって出入りする気体が前記防水防塵の通気部材を介して灰塵及び水分が内部に進入することを防止する効果を達成している。 In general, precision equipment is often equipped with a shell to improve the protection effect, to make the internal body more permanently operable, and to solve problems such as internal and external ventilation, heat dissipation, pressure difference adjustment, etc. In the past, ventilation holes were often opened in the shell or gaps were left to allow ventilation, but this did not prevent relatively small ash dust and water droplets from entering the inside and damaging the main body of the device. The inventor of the present invention developed a waterproof and dustproof ventilation valve structure in the early stage, and filed Republic of China Patent Application No. 100217832. This has achieved the effect of preventing intrusion into the interior.

しかし、考案者は、近年の実際の応用において、前述の防水防塵通気弁は機器の性能維持や寿命向上に貢献するものの、防水防塵通気部材の固定を補助する接着剤は、一部の特殊な応用環境で脱ガムの状況の発生を免れず、例えば、油やガスの含有量が比較的高い環境に応用する場合、油やガスの腐食を受けて脱ガムを生じ易く、更にその防水防塵性能に影響を及ぼし、通気弁が予期する効果又は使用期限に到達できなくなる。これに鑑み、考案者は、更なる改良の道を研究し、試行錯誤を重ねて本考案を完成させている。 However, in recent years, the inventor has found that in actual applications, although the above-mentioned waterproof and dustproof ventilation valves contribute to maintaining the performance and extending the lifespan of equipment, the adhesives that assist in fixing waterproof and dustproof ventilation members are It is inevitable that degumming will occur in the application environment. For example, if the application is in an environment with a relatively high content of oil or gas, degumming will easily occur due to the corrosion of oil or gas, and its waterproof and dustproof performance will deteriorate. The vent valve may not reach its expected effectiveness or expiration date. In view of this, the inventor has researched ways of further improvement and has completed the present invention through repeated trial and error.
