Description
本揭露係關於一種浮球液位開關裝置,特別是可以偵測液位的浮球液位開關裝置。The disclosure relates to a float level switch device, especially a float level switch device capable of detecting liquid level.
在現代社會中,浮球液位開關裝置應用於溶液槽中,例如水塔、冷卻液槽、化學溶液槽等。浮球液位開關裝置通常僅用於偵測固定的液位,例如高液位、低液位等。舉例來說,當在溶液槽中的溶液量過低時,浮球液位開關裝置會發送低液位警報。當在溶液槽中的溶液量過高時,浮球液位開關裝置會發送高液位警報。In modern society, float level switch devices are used in solution tanks, such as water towers, cooling liquid tanks, and chemical solution tanks. The float level switch device is usually only used to detect a fixed level, such as high level, low level, etc. For example, when the amount of solution in the solution tank is too low, the float level switch device will send a low level alarm. When the amount of solution in the solution tank is too high, the float level switch device will send a high level alarm.
然而,習知的浮球液位開關裝置無法偵測其他液位,以通知使用者當前溶液槽的溶液液位。通常需要額外的液位偵測裝置以得到溶液槽的溶液液位,從而增加額外的成本。因此,需要一種改進的浮球液位開關裝置。However, the conventional floating ball liquid level switch device cannot detect other liquid levels to notify the user of the current liquid level of the solution tank. Usually, an additional liquid level detection device is required to obtain the solution level of the solution tank, thereby increasing additional costs. Therefore, there is a need for an improved float level switch device.

The first floating ball has at least one first magnetic element, wherein the first floating ball can slide on the first sensing section. The first circuit includes a plurality of first switches and a plurality of resistors. The first switch is arranged at intervals in the hollow area corresponding to the first sensing section. The resistors are arranged in the hollow area corresponding to the first sensing section, wherein both ends of each of the resistors are individually connected to one of the first switches. The detector is connected to the first circuit, wherein when the first float and one of the first switches are on the same level, so that one of the first switches is turned on, the detector determines according to which one of the first switches is turned on Liquid level.

In this way, the model word "below" will cover two ways of reading upward and downward. In addition, the device may be turned to different orientations (rotated by 90 degrees or other orientations), and the spatially related words used here can be interpreted in the same way.
第1圖是根據本揭露實施例之浮球液位開關裝置的示意圖。浮球液位開關裝置100包括桿體102、浮球104(包括浮球104-1至104-3)、環狀物106(包括環狀物106-1至106-5)。應了解在浮球液位開關裝置100中,亦可能採用其他配置以及不同物件或省略某此物件,並且浮球液位開關裝置100僅為一範例,並且不限制本揭露。Figure 1 is a schematic diagram of a float level switch device according to an embodiment of the disclosure. The float
桿體102是筆直的桿狀物,並且桿體102是中空的(未顯示)。具體來說,在桿體102中具有中空區(未顯示),以在其中設置電路。桿體102可以是金屬管,金屬管的材料包括鐵、銅、不鏽鋼或其他合適金屬材料。如第1圖所示,桿體102垂直於在溶液槽114中的溶液116的液面(或桿體102的長軸垂直於溶液槽114中的溶液116的液面)並且浸入溶液116。The
如第1圖所示,在桿體102上有浮球104。具體來說,浮球104具有穿孔(亦可視為浮球104是環狀的),並且桿體102穿過浮球104。浮球104能夠在桿體102上下滑動(亦可視為浮球104在桿體102的外部,並且沿著桿體102滑動)。具體來說,浮球104-1能夠在桿體102的感測區段108上滑動;浮球104-2能夠在桿體102的感測區段110上滑動;浮球104-3能夠在桿體102的感測區段112上滑動。As shown in Figure 1, there is a
浮球104的材料可以是不鏽鋼、聚丙烯、聚氯乙烯、聚偏二氟乙烯或其他合適材料。在一些實施例中,浮球104的材料根據浮球液位開關裝置100將用於何種溶液來決定,以避免浮球104受到溶液的影響(侵蝕或破壞)。The material of the
第2A圖是根據本揭露實施例之浮球的剖面圖。浮球104有中空區202,使得浮球104整體構成一種低密度物體,並且可以浮於溶液116。因此,當浮球液位開關裝置100設置在溶液槽114時,浮球104會隨著溶液的液位高低而在桿體102上下移動。另外,如第2A圖所示,浮球104可更包括磁性元件204,設置在中空區202中。磁性元件204是環形的,並且用於桿體102的中空區中的電路(於後續說明)。在一些實施例中,浮球104包括多個磁性元件204,浮球104間隔地設置在中空區202中,如在第2B圖中的浮球104的俯視剖面圖。磁性元件204可以是磁鐵,其材料可以是鐵氧體、鋁鎳鈷合金或其他合適的鐵磁性材料。FIG. 2A is a cross-sectional view of a floating ball according to an embodiment of the disclosure. The
再參照第1圖,環狀物106設置在桿體102上。環狀物106用於將浮球104個別地限制在感測區段上(感測區段108至112)。具體來說,環狀物106-1和環狀物106-2設置在感測區段108的兩個末端,以將浮球104-1限制在感測區段108上移動;環狀物106-2和環狀物106-3設置在感測區段110的兩個末端,以將浮球104-2限制在感測區段110上移動;環狀物106-4和環狀物106-5設置在感測區段112的兩個末端,以將浮球104-3限制在感測區段112上移動。環狀物106可以是塑膠環、金屬環或橡膠環(O形環(O-ring))。在一些實施例中,環狀物106是桿體102的環形凸塊(即環狀物106是桿體102的一部分)。在另一些實施例中,桿體102僅凸起一部分(非環形凸塊)以替代環狀物106。Referring to FIG. 1 again, the ring 106 is provided on the
第3A圖至第3D圖是根據本揭露實施例之浮球液位開關裝置的剖面圖以及相關電路的示意圖。浮球液位開關裝置300浸入溶液槽302的溶液304中。浮球液位開關裝置300包括桿體306、浮球316(包括浮球316-1至316-3)、環狀物320(包括環狀物320-1至320-5)、電路322。浮球液位開關裝置300更包括中空區308、感測區段310至314。浮球316-1至316-3各自包括磁性元件318,磁性元件318與磁性元件204相似,此不再詳細描述。桿體306與桿體102相似、浮球316與浮球104相似、環狀物320與環狀物106相似,此不再詳細描述。

電路322包括開關324(包括開關324-1至324-8)和複數電阻326,並且電路322連接至電壓源330、電壓源332和偵測器328。開關324是磁簧開關,當浮球316的磁性元件318與開關324在同一水平面時,開關324會開啟(連接)。偵測器328可以是偵測晶片、電腦、計算系統等,並可包括處理器、記憶體等,以偵測各種訊號(電壓、電流等)或接收指令,並且執行各種指令、計算、軟體等。
The
如第3A圖至第3D圖所示,開關324-2至324-6由上而下間隔地設置在對應感測區段310的中空區308中(沿著桿體306的長軸),其中開關324-2至324-6的一端耦接至電壓源332,並且開關324-2至324-6的另一端耦接至偵測器328。每個電阻326的兩端個別地連接至一個開關324,並且每個電阻326耦接至電壓源332。這些耦接至電壓源332的開關324(開關324-2至324-6)和電阻326構成電路322的第一電路,其中電阻326構成分壓裝置,提供不同分壓至個別的開關324(開關324-2至324-6),當浮球316-1與開關324之一者實質上在同一水平面,使得開關324之一者開啟時,
偵測器328可以接收到所開啟的開關324連接的分壓。應理解,第一電路可以有更多的開關324和電阻326,本揭露不限於此。
As shown in FIGS. 3A to 3D, the switches 324-2 to 324-6 are arranged in the hollow area 308 (along the long axis of the rod 306) corresponding to the
開關324-1設置在對應感測區段310的中空區308中,並且在開關324-2至324-6的上方;開關324-7設置在對應感測區段312的中空區308中,並且在開關324-2至324-6的下方;開關324-8設置在對應感測區段314的中空區308中,並且在開關324-7的下方。開關324-1、開關324-7以及開關324-8的一端耦接至電壓源330,並且開關324-1、開關324-7以及開關324-8的另一端耦接至偵測器328。這些耦接至電壓源330的開關324(開關324-1、開關324-7以及開關324-8)構成電路322的第二電路。
The switch 324-1 is provided in the
由於浮球316在溶液304受到浮力,浮球316會隨著溶液304的液位移動。當浮球316的磁性元件318與開關324實質上在同一水平面上時,開關324會受到磁性元件318的磁場影響而開啟(連接),並且偵測器328可以根據所偵測的電壓(分壓)確定液位或發出警報訊號。
Since the float 316 is buoyant in the
舉例來說,如第3A圖所示,浮球316-1隨著溶液304的液位334移動至與開關324-3在同一水平面上,使得開關324-3受到浮球316-1的磁性元件318的磁場影響而開啟(連接),而偵測器328的埠口D接通至電壓源332。在此實施例中,電壓源332所輸出的電壓會因為電阻326(分壓裝置)而分壓,而偵測器328可以根據所開啟的開關324接到的分壓確定液位(在偵測器328中具有分壓與其對應液位的資料)。舉例來說,電壓源332的電壓被電阻326分壓,當開關324-3開啟,偵測器328會接收到電壓(分壓)V
2,偵測器328可以根據電壓V
2偵測到溶液304的液位334。當開關324-4開啟,偵測器328會接收到V
3的電壓(分壓),偵測器328可以根據電壓V
3偵測到溶液304的液位334,以此類推。在此實施例中,電壓源332的電壓被電阻326(分壓裝置)在每個開關324分壓成電壓V
1至V
20(部分未顯示)。
For example, as shown in Figure 3A, the float 316-1 moves with the
另外,偵測器328偵測到液位334後,會將溶液304的液位334顯示在顯示器(未顯示)。在一些實施例中,偵測器328會將溶液304的當前容量顯示在顯示器。在一些實施例中,電路322的第一電路可以透過電壓/電流轉換器連接至偵測器328。第一電路的輸出電壓(分壓)會轉換成電流輸入至偵測器328,偵測器328根據此電流確定液位。In addition, after the
如果溶液槽302的液位334過高(即溶液槽302的當前溶液304過多),偵測器328會發出高液位警報訊號。舉例來說,如第3B圖所示,溶液304的液位334過高,浮球316-1隨著溶液304的液位334移動至與開關324-1實質上在同一水平面上,使得開關324-1受到浮球316-1的磁性元件318的磁場影響而開啟(連接),而偵測器328的埠口H接通至電壓源330。埠口H亦可稱為高液位警報埠口,偵測器328透過埠口H接收到電壓源330的電壓(例如:24V)後,偵測器328會發出高液位警報訊號。高液位警報訊號可以藉由顯示器接收,使得顯示器顯示高液位警報。在一些實施例中,高液位警報訊號可以藉由蜂鳴器接收,使得蜂鳴器發出高液位警報聲。If the
如果溶液槽302的液位334過低(即溶液槽302的當前溶液304過低),偵測器328會發出低液位警報訊號。舉例來說,如第3C圖所示,溶液304的液位334過低,浮球316-2隨著溶液304的液位334移動至與開關324-7實質上在同一水平面上,使得開關324-7受到浮球316-2的磁性元件318的磁場影響而開啟(連接),而偵測器328的埠口L接通至電壓源330。埠口L亦可稱為低液位警報埠口,偵測器328透過埠口L接收到電壓源330的電壓後,偵測器328會發出低液位警報訊號。低液位警報訊號可以藉由顯示器接收,使得顯示器顯示低液位警報。在一些實施例中,低液位警報訊號可以藉由蜂鳴器接收,使得蜂鳴器發出低液位警報聲。If the
如果溶液槽302的液位334將接近溶液槽302的槽底(即溶液槽302的當前溶液304將耗盡),偵測器328會發出極限液位警報訊號。舉例來說,如第3D圖所示,溶液304的液位334將接近溶液槽302的槽底,浮球316-3隨著溶液304的液位334移動至與開關324-8在同一水平面上,使得開關324-8受到浮球316-3的磁性元件318的磁場影響而開啟(連接),而偵測器328的埠口LL接通至電壓源330。埠口LL亦可稱為極限液位警報埠口,偵測器328透過埠口LL接收到電壓源330的電壓後,偵測器328會發出極限液位警報訊號。極限液位警報訊號可以藉由顯示器接收,使得顯示器顯示極限液位警報。在一些實施例中,高液位警報訊號可以藉由蜂鳴器接收,使得蜂鳴器發出極限液位警報聲。If the
相較於現有技術,本發明之實施例提供多個優點,並應了解其他實施例可提供不同優點,於此不須討論全部優點,並且全部實施例無特定優點。Compared with the prior art, the embodiments of the present invention provide multiple advantages, and it should be understood that other embodiments can provide different advantages. It is not necessary to discuss all the advantages here, and all the embodiments have no specific advantages.
透過使用本揭露實施例,浮球液位開關裝置不僅可以在溶液槽的液位過高、過低或將接近槽底時發出警報通知使用者,更可以在通常使用浮球液位開關裝置時顯示溶液槽的當前液位或溶液容量。如此一來,溶液槽不需要設置額外的液位偵測裝置以得到溶液槽的溶液液位,從而增加額外的成本。Through the use of the disclosed embodiments, the float level switch device can not only issue an alarm to notify the user when the liquid level of the solution tank is too high, too low, or will approach the bottom of the tank, but also can be used when the float level switch device is usually used. Display the current level or solution capacity of the solution tank. In this way, the solution tank does not need to be provided with an additional level detection device to obtain the solution level of the solution tank, thereby increasing additional costs.
