The utility model has the advantages of simple structure, low cost, and prolonged film opening; and the life of the mouth is suitable for the application of the membrane switch and the related fields of manufacture. [Prior Art] Since the membrane switch has the advantages of lightness and thinness, it is suitable for miniaturization and quantization requirements, so it is widely used in various electronic product instruments, communication slap machine tools, and devices controlled by microcomputer. A complete machine control system, such as a notebook computer, is one of the preferred applications. As shown in Figure 1 and Figure 2, the membrane switch 1 is formed by overlapping a plurality of membranes 1 and 12, and a backing glue is adhered between the membranes η and 12 to prevent moisture from penetrating into each other. The film η, 12 causes damage to the line or causes a new way. However, if the membrane switch 10 is completely sealed, the physical environment (such as air pressure, temperature, humidity, etc.) between the films 11 and 12 cannot be balanced with the external physical environment. The heat expansion and contraction phenomenon occurs, so that the film is changed, the pitch is changed, and the pressing or tightening is applied to cause a short circuit. Therefore, the general practitioner 1 sets the air passage 13 on the membrane switch 10, and the air passage 13 is at one end 132. Connected to the membrane switch 1 气 气 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 Ventilation at the edge of 15 • =31' (10) (four) _, 12 (four) balance with external pressure reduction to avoid heat ups and downs. As shown in FIG. 2, the membrane switch 1 is disposed in the casing 2 of the machine table: 'usually disposed in the casing 20 is a metal substrate u for carrying the membrane switch 10' and then the film The switch 1G is stacked with other components such as a button. The membrane switch 10 can convect the outside air through the vent 1312 of the air passage 13, but when the machine performs a waterproof test, or uses #, the water is inadvertently When liquid such as juice or coffee is poured on the machine table, or when it is exposed to rain and water when it is used outdoors, the liquid can easily flow into the bottom plate 21 and cannot be discharged, so that the membrane switch 1 is soaked in the pool, and the liquid is also The venting port 131 may be infiltrated into the air venting passage 13, causing the membrane switch 1 to be short-circuited or damaged. In order to solve the aforementioned problems, some operators are attached to the ventilating=two 31-adhesive waterproof and breathable tape, and after long-term immersion, The waterproof and breathable tape will still fall off and will not solve the waterproof problem at all. [New content] In view of the lack of the prior art, the main purpose of this creation is to propose a kind of membrane switch waterproof structure. The venting port has a certain height by a simple structure supporting the membrane switch, and its structure is simple. Low cost and extended membrane switch life and machine life. In order to achieve the above object, the present invention provides a membrane switch waterproof structure, comprising: a membrane switch comprising at least two layers of film, an air passage is provided between the membranes; M311110 a + to an air passage, is provided Between the membrane switch membranes, the middle end of the air passage has a venting one end of which is connected to the air passage of the membrane switch; the at least two layers of the air passage of the air passage are disposed in the air passage The peripheral vent is formed in a suspended state; the air passage and the spacer have at least one spacer disposed at the bottom of the air passage;

言月麥閱圖三及圖四所示，本創作提供之薄膜開關防水 結構，其包含一薄膜開關30，該薄膜開關30係由至少兩 層薄膜3卜32構成，該薄膜3卜32係藉由黏膠層打相互 黏合，且於該薄膜31、32之間設有氣道34 ;於該薄 關30之該溥膜3卜32間設有—通氣道33，該通氣道扣 之其中-端具有一通氣口 33卜該通氣道33之另一端咖 係連通於該之氣道34;於該通氣道犯之 設有透空部36，藉由該透空部36之設置，使得該通氣道 33與該通氣口 331形成可上下翻動之懸空狀態。As shown in Figure 3 and Figure 4, the membrane switch waterproof structure provided by the present invention comprises a membrane switch 30, which is composed of at least two layers of film 3, 32, which are The adhesive layer is bonded to each other, and an air passage 34 is disposed between the membranes 31 and 32. The air passage 33 is disposed between the diaphragms 3 and 32 of the thin seal 30, and the air passage buckle has a middle end thereof. The other end of the air passage 33 having a vent 33 is connected to the air passage 34; the air passage is provided with a venting portion 36, and the air passage 33 is provided by the venting portion 36. The vent 331 is formed in a suspended state that can be flipped up and down.
…請參閱圖四所示，若該薄膜3卜32之硬度適當，可將 該懸空之通氣道33向上翻折，使該通氣口 331上仰一角度 Θ，如此可使該通氣口 331免於浸泡於容置該薄膜開關$ 之底板21可能積存之水或其他液體中。 然為避免該通氣道33因重力作用或受外力壓迫而下 沉，因此，請參閱圖五所示，於該通氣道33底部設置—墊 片38,用以撐托該通氣道33,該墊片肋係設置於該底柘 21與該通氣道33之間。使該通氣口 331具有一定高度， 可維持上仰狀態；為達到確實撐托該通氣道33之目:，該 墊片38必須具有一定厚度及硬度，該墊片38之厚度D2必 須大於該薄膜開關3〇之厚度D1，以確保該通氣口 331可 被上抬至少脫離該薄膜開關30之上表面；而該墊片38之 硬度則必須大於該薄膜開關3 〇之硬度’以確保不致因該通 氣道3 3之重力壓迫而—划 卜， 墊片38移位，可於該墊片38與該通氣二=^致: ==膠_物，以使_38確實附著= ^逼33底部，亦可於該墊片38與該通氣道33及 間’同時設置黏膠或雙面膠等黏著物 使 墊片％確實定位之目的;至於該墊片38::== ，需要採用塑膠、金屬材質或泡棉其t之-或1組人二 數量或尺柯料⑽軌道33讀量或財 登片按托_開關之通氣道，使其通氣口 一 構簡單、成本低’並可延長薄膜開關以及機台：：用 ^ ’適用於_f制及製造相_域，確 步性、新穎性與實用性。 /、有/、進 处惟以上所述者’僅為本創作之最佳實補而已，當 之限疋本創作所實施之範圍。即大凡依本創作申於專 :二圍=之=變化與修飾’皆應仍屬於本創作專利涵 ^之祀圍内，謹請貴審查委員明鑑，並祈惠准，是所至 【圏式簡單說明】 圖一係習知薄膜開關之結構示意圖。 圖二係f知薄膜關設置於機台殼體内之剖面結構 〇 圖三係本創作通氣道較佳實施例之結構示意圖。 M311110 …圖四係本創作通氣道較佳實施例之剖面結構示意圖。 圖五係本創作通氣道配合墊片較佳實施利之剖面結構 示意圖。 【主要元件符號說明】 30-薄膜開關 31、32-薄膜 33- 通氣道 331- 通氣口 332- 通氣道之另一端 34- 氣道 36- 透空部 37- 黏膠層 38- 墊片 D1-薄膜開關之厚度 D2-墊片之厚度 角度 10As shown in FIG. 4, if the hardness of the film 3 is 32, the floating air passage 33 can be folded upwards, so that the air vent 331 is tilted up by an angle, so that the air vent 331 can be prevented from being Soaked in water or other liquid that may be accumulated in the bottom plate 21 in which the membrane switch $ is housed. Therefore, in order to prevent the air passage 33 from sinking due to gravity or being pressed by an external force, a spacer 38 is disposed at the bottom of the air passage 33 to support the air passage 33, as shown in FIG. A rib line is disposed between the bottom cymbal 21 and the air passage 33. The vent 331 has a certain height to maintain the up state; to achieve the purpose of supporting the air passage 33: the gasket 38 must have a certain thickness and hardness, and the thickness D2 of the gasket 38 must be larger than the film. The thickness D1 of the switch 3〇 ensures that the vent 331 can be lifted at least from the upper surface of the membrane switch 30; and the hardness of the gasket 38 must be greater than the hardness of the membrane switch 3 以 to ensure that The gravity of the air passage 3 3 is pressed, and the spacer 38 is displaced.
