The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only directions referring to the additional drawings. Therefore, the directional terminology used is for the purpose of illustration and not limitation.
請參閱第1A圖、第1B圖、第2A圖及第2B圖，本實施例之防水裝置100可以是任何需要具有防水功能之裝置(例如，行動電話或相機等3C產品)，並且其主要包括有一殼體110、一真空檢測機構120、一單向排氣機構130、一第一金屬探測感測器141、一第二金屬探測感測器142及一控制器150。在此，為了方便說明防水裝置100之內部構造，與殼體110結合之一上蓋或一蓋體是被省略掉。 Referring to FIG. 1A, FIG. 1B, FIG. 2A and FIG. 2B, the waterproof device 100 of the present embodiment may be any device that requires a waterproof function (for example, a 3C product such as a mobile phone or a camera), and mainly includes There is a housing 110, a vacuum detecting mechanism 120, a one-way exhaust mechanism 130, a first metal detecting sensor 141, a second metal detecting sensor 142 and a controller 150. Here, in order to facilitate the description of the internal structure of the waterproof device 100, an upper cover or a cover combined with the housing 110 is omitted.
殼體110具有一凹入部111。在此，殼體110可以是由塑膠或金屬所製成，但其並不以此為限。換句話說，殼體110 亦可以是由其他的材料所製成。 The housing 110 has a recessed portion 111. Here, the housing 110 may be made of plastic or metal, but it is not limited thereto. In other words, the housing 110 It can also be made of other materials.
如第1B圖及第2B圖所示，真空檢測機構120是設置於殼體110之凹入部111之內，並且真空檢測機構120具有一按鈕121、一金屬板122及一彈性元件123。 As shown in FIGS. 1B and 2B, the vacuum detecting mechanism 120 is disposed in the recessed portion 111 of the housing 110, and the vacuum detecting mechanism 120 has a button 121, a metal plate 122, and an elastic member 123.
按鈕121是密合於凹入部111之上，並且按鈕121可相對於凹入部111移動於一第一位置(如第1A圖及第1B圖所示)與一第二位置(如第2A圖及第2B圖所示)之間。在此，為了達到使按鈕121密合於凹入部111之上的目的，按鈕121是由可稍微彈性變形之彈性材料所製成。 The button 121 is adhered to the recessed portion 111, and the button 121 is movable relative to the recessed portion 111 at a first position (as shown in FIGS. 1A and 1B) and a second position (such as FIG. 2A and Between Figure 2B). Here, in order to achieve the purpose of bringing the button 121 into close contact with the recessed portion 111, the button 121 is made of an elastic material which is slightly elastically deformable.
仍如第1B圖及第2B圖所示，金屬板122是連接於按鈕121。換言之，金屬板122可以隨著按鈕121之作動而移動。 Still as shown in FIGS. 1B and 2B, the metal plate 122 is connected to the button 121. In other words, the metal plate 122 can move as the button 121 moves.
彈性元件123是連接於凹入部111與按鈕121之間。在本實施例之中，彈性元件123可以是一彈簧之型式。此外，特別的是，彈性元件(或彈簧)123之選用可以依據防水裝置100所需的防水程度或等級而定。更詳細的來說，當彈性元件123處於最大之壓縮狀態時，其所提供之壓縮彈力即是與環境水壓對彈性元件123所產生之力相等。舉例來說，當防水裝置100之防水程度設定為水深1米時，則可以選用在最大壓縮狀態時所提供之壓縮彈力與水深1米時之環境水壓所產生之力相等的彈性元件123，依此類推。換言之，依據不同的防水程度或等級，不同彈性係數之彈性元件123可以被選用。 The elastic member 123 is connected between the recessed portion 111 and the button 121. In the present embodiment, the elastic member 123 may be of a spring type. Moreover, in particular, the selection of the elastic element (or spring) 123 may depend on the degree of waterproofing or grade required for the waterproof device 100. In more detail, when the elastic member 123 is in the maximum compressed state, the compressive elastic force it provides is equal to the force generated by the ambient water pressure on the elastic member 123. For example, when the waterproofing degree of the waterproof device 100 is set to a water depth of 1 m, the elastic member 123 which is provided in the maximum compression state and has the same compressive force as the environmental water pressure at a water depth of 1 m can be selected. So on and so forth. In other words, depending on the degree of waterproofing or grade, different elastic coefficients of the elastic element 123 can be selected.
仍如第1B圖及第2B圖所示，單向排氣機構130是設置於殼體110之上，其可用來排出殼體110內之氣體。更具體而言，單向排氣機構130包括有一排氣孔121及一單向排氣橡膠 132。排氣孔131是成型於殼體110之上，而單向排氣橡膠132是從殼體110之內部包覆住排氣孔131。在此，由於單向排氣橡膠132之結構設計，氣體只能從殼體110內經由排氣孔131排出至殼體110之外部，而無法從殼體110之外部經由排氣孔131進入至殼體110之內。 Still as shown in FIGS. 1B and 2B, the one-way exhaust mechanism 130 is disposed above the housing 110 and can be used to exhaust gas within the housing 110. More specifically, the one-way exhaust mechanism 130 includes a venting opening 121 and a one-way venting rubber 132. The vent hole 131 is formed on the casing 110, and the unidirectional exhaust rubber 132 covers the vent hole 131 from the inside of the casing 110. Here, due to the structural design of the unidirectional exhaust rubber 132, the gas can only be discharged from the inside of the housing 110 through the vent hole 131 to the outside of the housing 110, and cannot enter from the outside of the housing 110 via the vent hole 131. Inside the housing 110.
第一金屬探測感測器141是設置於殼體110之內，其可用來選擇性地感測位於第一位置處之金屬板122。舉例來說，在本實施例之中，第一金屬探測感測器141可以是一極限感測器之形式。 The first metal detection sensor 141 is disposed within the housing 110 and is operable to selectively sense the metal plate 122 at the first location. For example, in the present embodiment, the first metal detecting sensor 141 may be in the form of a limit sensor.
第二金屬探測感測器142是設置於殼體110之內，其可用來選擇性地感測位於第二位置處之金屬板122。同樣地，在本實施例之中，第二金屬探測感測器141可以是一極限感測器之形式。 The second metal detection sensor 142 is disposed within the housing 110 and is operable to selectively sense the metal plate 122 at the second location. Similarly, in the present embodiment, the second metal detecting sensor 141 may be in the form of a limit sensor.
控制器150是電性連接於第一金屬探測感測器141及第二金屬探測感測器142，其可根據第一金屬探測感測器141及第二金屬探測感測器142之感測資訊而選擇性地發出警示(例如，聲音或光線)。 The controller 150 is electrically connected to the first metal detecting sensor 141 and the second metal detecting sensor 142, and can sense information according to the first metal detecting sensor 141 and the second metal detecting sensor 142. Instead, an alert (eg, sound or light) is selectively issued.
接下來說明防水裝置100之運作方式。 Next, the operation of the waterproof device 100 will be described.
首先，就防水裝置100於使用前之防水性能檢測而言，一使用者可以先反覆按壓真空檢測機構120之按鈕121，以迫使殼體110內之氣體經由單向排氣機構130排出。直到真空檢測機構120之彈性元件123處於最大之壓縮狀態且不會自然回復時，此即表示殼體110或防水裝置100內之真空吸力(或氣壓)與所選用之彈性元件123之最大壓縮彈力相等，亦即，防水裝 置100內之真空壓力(或內部壓力)已到達防水等級之環境壓力。此時，如第2B圖所示，金屬板122會隨著按鈕121而位於第二位置處，而第二金屬探測感測器142會感測得知位於第二位置處之金屬板122。在此，依據防水裝置100所定義之真空標準來決定一真空檢測時間。舉例來說，當控制器150得知第二金屬探測感測器142係長時間(例如，3秒鐘)感測到位於第二位置處之金屬板122時，控制器150便會啟動真空檢測模式。 First, in the waterproof performance detection of the waterproof device 100 before use, a user may first press the button 121 of the vacuum detecting mechanism 120 to force the gas in the housing 110 to be discharged through the one-way exhaust mechanism 130. Until the elastic member 123 of the vacuum detecting mechanism 120 is in the maximum compression state and does not naturally recover, this means the vacuum suction force (or air pressure) in the housing 110 or the waterproof device 100 and the maximum compressive elastic force of the selected elastic member 123. Equal, that is, waterproof The vacuum pressure (or internal pressure) within 100 has reached the ambient pressure of the waterproof rating. At this time, as shown in FIG. 2B, the metal plate 122 is located at the second position with the button 121, and the second metal detecting sensor 142 senses the metal plate 122 at the second position. Here, a vacuum detection time is determined according to the vacuum standard defined by the waterproof device 100. For example, when the controller 150 knows that the second metal detecting sensor 142 senses the metal plate 122 at the second position for a long time (for example, 3 seconds), the controller 150 activates the vacuum detecting mode. .
如上所述，在真空檢測時間之內，倘若第一金屬探測感測器141並未感測到金屬板122(亦即，金屬板122並未隨著按鈕121返回至第一位置處)，則表示彈性元件123仍保持在(最大)壓縮狀態之下，而此即可判定防水裝置100於使用前之防水性能檢測過關。此時，控制器150不會發出任何的警示。 As described above, if the first metal detecting sensor 141 does not sense the metal plate 122 within the vacuum detecting time (that is, the metal plate 122 does not return to the first position with the button 121), then It indicates that the elastic member 123 is still kept under the (maximum) compression state, and it can be determined that the waterproof device 100 has passed the waterproof performance detection before use. At this time, the controller 150 does not issue any warning.
反之，在真空檢測時間之內，倘若第一金屬探測感測器141感測到金屬板122(亦即，金屬板122已隨著按鈕121返回至第一位置處)，則表示彈性元件123無法保持在壓縮狀態之下，而此即可判定防水裝置100於使用前之防水性能檢測未過關。此時，控制器150便會發出警示通知使用者防水裝置100已失去防水之功能。 On the contrary, within the vacuum detection time, if the first metal detecting sensor 141 senses the metal plate 122 (that is, the metal plate 122 has returned to the first position with the button 121), it means that the elastic member 123 cannot It is kept under the compressed state, and it can be determined that the waterproof performance of the waterproof device 100 before use is not passed. At this time, the controller 150 issues an alert to notify the user that the waterproof device 100 has lost the waterproof function.
在另一方面，就防水裝置100於到達防水極限時發出警示之運作而言，當防水裝置100處於水中或高壓環境中時，真空檢測機構120之按鈕121及金屬板122會因環境壓力而被壓入。接著，當環境壓力逐漸增加(例如，在水中逐漸下潛)而使得第二金屬探測感測器142感測到金屬板122時，如第2B圖所示，控制器150便會發出警示通知使用者防水裝置100已到 達防水的極限，而不可再下潛或是再加壓。 On the other hand, in terms of the operation of the waterproof device 100 when the waterproof device 100 reaches the waterproof limit, when the waterproof device 100 is in the water or high-pressure environment, the button 121 and the metal plate 122 of the vacuum detecting mechanism 120 are subjected to environmental pressure. push into. Then, when the ambient pressure is gradually increased (for example, gradually dive in the water) and the second metal detecting sensor 142 senses the metal plate 122, as shown in FIG. 2B, the controller 150 issues an alert notification to use. Waterproof device 100 has arrived Reach the limit of waterproofing, and no longer dive or repressurize.
綜上所述，本發明所揭露之防水裝置可在不需外接任何測試儀器之情況下提供使用前之防水性能檢測以及在到達防水極限時發出警示之功能，因而可有利於使用者之使用與操作判斷。 In summary, the waterproof device disclosed in the present invention can provide the waterproof performance detection before use and the function of warning when the waterproof limit is reached without any external test equipment, thereby facilitating the use of the user. Operational judgment.
雖然本發明已以較佳實施例揭露於上，然其並非用以限定本發明，此技術領域具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the scope of the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
