Description
本新型有關於一種溶氧感測裝置，特別是一種具自潔功能的溶氧感測裝置。The invention relates to a dissolved oxygen sensing device, in particular to a dissolved oxygen sensing device with self-cleaning function.
一般來說，為了計算出水中的氧濃度，使用者會將水質感測器置入於水中以感測並計算出水中的溶氧量。Generally, in order to calculate the oxygen concentration in the water, the user places the water quality sensor in the water to sense and calculate the dissolved oxygen in the water.
然而，由於水質感測器的探頭由於長時間浸於水中，容易附著藻類、微生物、蟲卵以及黏稠穢物等，因此水質感測器會逐漸受到環境汙染而導致水質感測器因數值衰減影響正確數值的量測，亦即感測精度會受到影響，其中又以光學溶氧感測器最容易因髒汙而失效。因此，水質傳感器仍有改善的空間。However, since the probe of the water quality sensor is easily immersed in water for a long time, it is easy to adhere to algae, microorganisms, eggs, and sticky sputum, so the water quality sensor is gradually polluted by the environment and the water quality sensor is affected by the numerical attenuation. The measurement of the correct value, that is, the sensing accuracy will be affected, and the optical dissolved oxygen sensor is most likely to fail due to contamination. Therefore, there is still room for improvement in water quality sensors.
有鑑於此，本新型提供一種具自潔功能的溶氧感測裝置，藉以有效地達到對光學薄膜的清潔效果，以增加溶氧感測的準確性、使用上的便利性及溶氧感測裝置的使用壽命。In view of this, the present invention provides a dissolved oxygen sensing device with self-cleaning function, thereby effectively achieving the cleaning effect on the optical film, thereby increasing the accuracy of the dissolved oxygen sensing, the convenience in use, and the dissolved oxygen sensing.

清潔模組160可拆卸地裝設於本體110，例如清潔模組160以旋轉的方式裝設於本體110，並與本體110連接。清潔模組160具有底部161與側壁162。其中，底部161與側壁162形成容置空間，並且本體110的第一部分111位於容置空間。底部161鄰近於光學薄膜120且設置有電極套件170。電極套件170產生電解效應，以對光學薄膜120進行清潔。The cleaning module 160 is detachably mounted on the body 110. For example, the cleaning module 160 is rotatably mounted on the body 110 and connected to the body 110. The cleaning module 160 has a bottom 161 and a side wall 162. The bottom portion 161 and the side wall 162 form an accommodating space, and the first portion 111 of the body 110 is located in the accommodating space. The bottom 161 is adjacent to the optical film 120 and is provided with an electrode package 170. Electrode kit 170 produces an electrolytic effect to clean optical film 120.
在一實施例中，電極套件170包括電極板171與172，如圖1和圖2所示。電極板171與172相互平行，且電極板171和172與底部161平行設置。其中，電極板171和172例如為網格狀的電極板。在本實施例中，電極板171為陰極電極板且電極板172為陽極電極板，或是電極板171為陽極電極板且電極板172為陰極電極板。並且，在圖1和圖2中，電極板171與172的數量是以2個為例，但本實施例不限於此，使用者亦可視其需求自行增加電極板的數量，例如增加為4個、6個或6個以上，都可達到類似的效果。In an embodiment, the electrode assembly 170 includes electrode plates 171 and 172, as shown in FIGS. 1 and 2. The electrode plates 171 and 172 are parallel to each other, and the electrode plates 171 and 172 are disposed in parallel with the bottom 161. Among them, the electrode plates 171 and 172 are, for example, grid-shaped electrode plates. In the present embodiment, the electrode plate 171 is a cathode electrode plate and the electrode plate 172 is an anode electrode plate, or the electrode plate 171 is an anode electrode plate and the electrode plate 172 is a cathode electrode plate. In addition, in FIG. 1 and FIG. 2, the number of the electrode plates 171 and 172 is exemplified by two, but the embodiment is not limited thereto, and the user may increase the number of the electrode plates by themselves, for example, by four. A similar effect can be achieved with six or more.
在另一實施例中，電極套件170包括電極板173與174，如圖3和4所示。電極板173與174互相平行，且電極板173和174與底部161垂直設置。在本實施例中，電極板173為陰極電極板且電極板174為陽極電極板，或是電極板173為陽極電極板且電極板174為陰極電極板。並且，在圖3和圖4中，電極板173與174的數量是以6個為例，但本實施例不限於此，使用者亦可視其需求自行增加電極板的數量，例如增加為2個、4個或6個以上，都可達到類似的效果。In another embodiment, electrode kit 170 includes electrode plates 173 and 174, as shown in Figures 3 and 4. The electrode plates 173 and 174 are parallel to each other, and the electrode plates 173 and 174 are disposed perpendicular to the bottom 161. In the present embodiment, the electrode plate 173 is a cathode electrode plate and the electrode plate 174 is an anode electrode plate, or the electrode plate 173 is an anode electrode plate and the electrode plate 174 is a cathode electrode plate. In addition, in FIG. 3 and FIG. 4, the number of the electrode plates 173 and 174 is exemplified by six, but the embodiment is not limited thereto, and the user can increase the number of the electrode plates by themselves, for example, by two. A similar effect can be achieved with 4 or more.
在本實施例中，電極套件170設置鄰近於光學薄膜120，且電極套件170包括電解電壓的陰極電極板(例如電極板171或電極板173)及陽極電極板(例如電極板172或電極板174)，而陰極電極板及陽極電極板在通電後會產生電解效應，使得水中的水分子與Cl -離子會被電解。其中，陽極電極板吸附Cl -離子生成氯氣（Cl 2），也把水氧化成氧氣（O 2）和H +離子，後者和Cl -及OCl -結合成HCl或HOCl。陰極電極板吸附Na +離子，生成金屬鈉，鈉和水反應生成氫氣（H 2）和OH -離子，後者並與Na +結合成NaOH。 In the present embodiment, the electrode assembly 170 is disposed adjacent to the optical film 120, and the electrode assembly 170 includes a cathode electrode plate (eg, the electrode plate 171 or the electrode plate 173) that electrolyzes the voltage and an anode electrode plate (eg, the electrode plate 172 or the electrode plate 174). And the cathode electrode plate and the anode electrode plate generate an electrolytic effect after being energized, so that water molecules and Cl − ions in the water are electrolyzed. Among them, the anode electrode plate adsorbs Cl - ions to generate chlorine gas (Cl 2 ), and also oxidizes water into oxygen (O 2 ) and H + ions, and the latter combines with Cl - and OCl - to form HCl or HOCl. The cathode electrode plate adsorbs Na + ions to form sodium metal, which reacts with water to form hydrogen (H 2 ) and OH - ions, which combine with Na + to form NaOH.
接著，電極套件170利用電解產生的氣泡(O 2、H 2)來衝擊光學薄膜120，以藉由氣泡之動能來達到對光學薄膜120進行去汙的效果，使得感測模組130所感測的溶氧量更為準確，以增加使用的便利性。另外，電極套件170利用電解產生的HOCl來抑制水中的菌與藻類的滋長，達到抗污之效果。 Next, the electrode assembly 170 impacts the optical film 120 by using bubbles (O 2 , H 2 ) generated by electrolysis to achieve the effect of decontaminating the optical film 120 by the kinetic energy of the bubbles, so that the sensing module 130 senses The dissolved oxygen amount is more accurate to increase the convenience of use. In addition, the electrode kit 170 utilizes HOCl generated by electrolysis to suppress the growth of bacteria and algae in the water to achieve an antifouling effect.
進一步來說，具自潔功能的溶氧感測裝置100更包括濾光片140。濾光片140設置在光學薄膜120與感測模組130之間，以進行濾光的操作，進而增加溶氧感測的效果。Further, the dissolved oxygen sensing device 100 having a self-cleaning function further includes a filter 140. The filter 140 is disposed between the optical film 120 and the sensing module 130 to perform a filtering operation, thereby increasing the effect of dissolved oxygen sensing.
另外，具自潔功能的溶氧感測裝置100更包括電路板150。電路板150設置於本體110內且位於本體110的第二部分112。電路板150連接感測模組130(亦即電路板150連接第一發光二極體131、第二發光二極體132與光電二極體133)與電極套件170，提供電力給感測模組130與電極套件170，使得感測模組130與電極套件170可正常運作。並且，電路板150接收螢光強度與相位差資訊以計算其對應的溶氧量。也就是說，感測模組130的光電二極體133感測並收集光學薄膜120的螢光強度與相位差資訊，並傳送至電路板150，使得電路板150可據以比較螢光強度與相位差資訊，以計算出水中的溶氧量(即環境中的氧濃度)。In addition, the dissolved oxygen sensing device 100 having a self-cleaning function further includes a circuit board 150. The circuit board 150 is disposed within the body 110 and is located at the second portion 112 of the body 110. The circuit board 150 is connected to the sensing module 130 (that is, the circuit board 150 is connected to the first light emitting diode 131, the second light emitting diode 132 and the photodiode 133) and the electrode assembly 170 to provide power to the sensing module. The 130 and the electrode assembly 170 enable the sensing module 130 and the electrode assembly 170 to function normally. And, the circuit board 150 receives the fluorescence intensity and phase difference information to calculate its corresponding dissolved oxygen amount. That is, the photodiode 133 of the sensing module 130 senses and collects the fluorescence intensity and phase difference information of the optical film 120, and transmits the information to the circuit board 150, so that the circuit board 150 can compare the fluorescence intensity with Phase difference information to calculate the amount of dissolved oxygen in the water (ie, the concentration of oxygen in the environment).
此外，側壁162上還設置有多個孔洞163，以便於增加清潔模組160內的水的流動，進而增加清潔的效果。並且，本體110與清潔模組160的形狀例如為圓柱型。In addition, a plurality of holes 163 are defined in the side wall 162 to increase the flow of water in the cleaning module 160, thereby increasing the cleaning effect. Moreover, the shape of the body 110 and the cleaning module 160 is, for example, a cylindrical shape.
